摘要: In this study, we present two new regularity criteria for three-dimensional
nematic liquid crystal flows. More precisely, we show that if delta(3)u is an element
of L-beta(0,T;L-alpha(R-3)) with 2/beta + 3/alpha <= 3(alpha+2)/4 alpha (alpha >
2), or u(3), del d is an element of L-beta/(0, T; L-alpha(R-3)) with 2/beta + 3/alpha
<= 3/4 + 1/2 alpha (alpha > 10/3), then the corresponding weak solution (u, d) can
be extended beyond T. (C) 2014 Elsevier Inc. All rights reserved.

摘要: A novel adaptive control approach is presented using extended fuzzy logic
systems without any rules. First, the extended fuzzy logic systems without any rules
are used to approximate the uncertainties. Then the sliding mode controllers via
the proposed extended fuzzy logic systems without any rules are proposed for
uniformly ultimately bounded (UUB) nonlinear systems. The adaptive laws are used
for estimating the approximation accuracies of fuzzy logic systems without any
rules, Lipschitz constants of uncertain functions and scalar factor, respectively,
which are not directly to estimate the coefficients of basis functions. Finally,
a compared simulation example is utilized to demonstrate the effectiveness of the
approach proposed in this paper.

摘要: In magnetic resonance (MR) imaging, image spatial resolution is determined
by various instrumental limitations and physical considerations. This paper
presents a new algorithm for producing a high-resolution version of a low-resolution
MR image. The proposed method consists of two consecutive steps: (1) reconstructs
a high-resolution MR image from a given low-resolution observation via solving a
joint sparse representation and nonlocal similarity L1-norm minimization problem;
and (2) applies a sparse derivative prior based post-processing to suppress blurring
effects. Extensive experiments on simulated brain MR images and two real clinical
MR image datasets validate that the proposed method achieves much better results
than many state-of-the-art algorithms in terms of both quantitative measures and
visual perception. (C) 2015 Elsevier Ltd. All rights reserved.

摘要: With the dramatically increasing prevalence of obesity and type 2 diabetes
mellitus (T2DM) worldwide, there is an urgent need for new strategies to combat
the growing epidemic of these metabolic diseases. Diet is an essential factor
affecting the development of and risk for obesity and T2DM and it can either help
or hurt. In searching for preventative and therapeutic strategies, it is therefore
advantageous to consider the potential of certain foods and their bioactive
compounds to reverse or prevent the pathogenic processes associated with metabolic
disease. Anthocyanins are naturally occurring polyphenolic compounds abundant in
dark-colored fruits, vegetables and grains. Epidemiological studies suggest that
increased consumption of anthocyanins lowers the risk of T2DM. Many in vitro and
in vivo studies also reveal an array of mechanisms through which anthocyanins could
prevent or reverse obesity- and T2DM-related pathologies including promotion of
antioxidant and anti-inflammatory activities, improvement of insulin resistance,
and hypolipidemic and hypoglycemic actions. Here, we summarize the data on
anthocyanin-mediated protection against obesity and T2DM and the underlying
mechanisms. Further population-based and long-term human intervention studies are
necessary to ultimately evaluate the use of anthocyanins for protection/prevention
against the development of obesity and T2DM.

摘要: Quantum correlations of a qutrit pair in Werner states undergoing local and
nonlocal unitary operations are quantified in terms of two different methods, i.e.,
quantum discord (Ollivier and Zurek in Phys Rev Lett 88:017901, 2001) and
measurement-induced disturbance (Luo in Phys Rev A 77:022301, 2008). Analytic
expressions of the two kinds of quantum correlations in the system are worked on
and found to be completely the same. By virtue of investigations and discussions,
we expose some distinct features of the correlations and their underlying physics.
More importantly, we found that both local and nonlocal unitary operations cannot
increase quantum correlation in a qutrit Werner state for the two quantifiers which
are concerned.

摘要: Quantum correlations (QCs), including quantum entanglement and those
different, are important quantum resources and have attracted much attention
recently. Quantum entanglement swapping as a kernel technique has already been
applied to quantum repeaters for successfully generating long-distance shared
maximally entangled qubit states. Long-distance shared QCs containing shared
entanglements are useful and important for some quantum information processing in
future quantum networks. In this paper, the concept of quantum entanglement repeater
is extended to that of QC repeater by generalizing quantum entanglement swapping
to QC swapping. Specifically, the swapping of QCs in a pair of Werner states through
a local bipartite von Neumann measurement is treated. Four different QC measures,
i.e., entanglement of formation (William in Phys Rev Lett 80:2245, 1998), quantum
discord (Ollivier and Zurek in Phys Rev Lett 88:017901, 2001), measurement-induced
disturbance (MID) (Luo in Phys Rev A 77:022301, 2008) and ameliorated MID (Girolami
et al. in J Phys A 44:352002, 2011), are employed to characterize and quantify QCs.
Properties and thresholds of all QCs which occur in the swapping process are
revealed, and two different phenomena are exposed and explained. It is found that
a long-distance shared QC can be generated from two short-distance ones via QC
swapping indeed; however, its amount cannot exceed the minimum one among the QCs
in the two initial states and in the measuring state as far as the four quantifiers
are concerned.

摘要: The berries of bilberry and black currant are a rich source of anthocyanins,
which are thought to have favorable effects on nonalcoholic steatohepatitis (NASH).
This study was designed to examine whether purified anthocyanins from bilberry and
black currant are able to limit the disorders related to NASH induced by a
methionine-choline-deficient (MCD) diet in mice. The results showed that treatment
with anthocyanins not only alleviated inflammation, oxidative stress, steatosis,
and even fibrosis but also improved depletion of mitochondrial content and damage
of mitochondrial biogenesis and electron transfer chain developed concomitantly
in the liver of mice fed the MCD diet. Furthermore, anthocyanins treatment promoted
activation of AMP-activated protein kinase (AMPK) and expression of peroxisome
proliferator-activated receptor-gamma coactivator-1a (PGC-1a). These data provide
evidence that anthocyanins possess significant protective effects against NASH and
mitochondrial defects in response to a MCD diet, with a mechanism maybe through
affecting the AMPK/PGC-1 alpha signaling pathways.

摘要: A probabilistic tripartite single-qubit operation sharing scheme is put
forward by utilizing a two-qubit and a three-qubit non-maximally entangled state
as quantum channels. Some specific comparisons between our scheme and another
probabilistic scheme are made. It is found that, if the product of the two minimal
coefficients characterizing channel entanglements is greater than 3/16, our scheme
is more superior than the other one. Nonetheless, the price is that more classical
and quantum resources are consumed, and the operation difficulty is rather
increased. Moreover, some important features of the scheme, such as its security,
probability and sharer symmetry, are revealed through concrete discussions.
Additionally, the experimental feasibility of our scheme is analyzed and
subsequently confirmed according to the current experimental techniques.

标题: Nonparametric VSS-APA based on precise background noise power estimate

摘要: The adaptive algorithm used for echo cancellation (EC) system needs to provide
1) low misadjustment and 2) high convergence rate. The affine projection algorithm
(APA) is a better alternative than normalized least mean square (NLMS) algorithm
in EC applications where the input signal is highly correlated. Since the APA with
a constant step-size has to make compromise between the performance criteria 1)
and 2), a variable step-size APA (VSS-APA) provides a more reliable solution. A
nonparametric VSS-APA (NPVSS-APA) is proposed by recovering the background noise
within the error signal instead of cancelling the a posteriori errors. The most
problematic term of its variable step-size formula is the value of background noise
power (BNP). The power difference between the desired signal and output signal,
which equals the power of error signal statistically, has been considered the BNP
estimate in a rough manner. Considering that the error signal consists of background
noise and misalignment noise, a precise BNP estimate is achieved by multiplying
the rough estimate with a corrective factor. After the analysis on the power ratio
of misalignment noise to background noise of APA, the corrective factor is
formulated depending on the projection order and the latest value of variable
step-size. The new algorithm which does not require any a priori knowledge of EC
environment has the advantage of easier controllability in practical application.
The simulation results in the EC context indicate the accuracy of the proposed BNP
estimate and the more effective behavior of the proposed algorithm compared with
other versions of APA class.

摘要: By using the bifurcation method of dynamical systems and numerical simulation
approach of differential equations, we investigate generalized KdV equation . Two
types of bounded traveling wave solutions are found, that is, the kink-like wave
and compacton-like wave solutions. The planar graphs of these solutions are
simulated by using software Mathematica; meanwhile, some interesting phenomena are
revealed, that is, under some conditions, the periodic wave can become the kink-like
wave and compacton-like wave, respectively, and the solitary wave can become the
kink-like wave. The exact kink-like wave and compacton-like wave solutions with
implicit or parameter expressions are given.

摘要: The effects of plasma environments on energies, oscillator strengths,
polarizabilities and hyperpolarizabilities for lithium atom have been calculated
by combining the I-dependent model potential of free lithium atom and linear
variation method based on B-spline basis functions. The influence of plasma on
lithium atom is represented by the Debye screened potential, which describes
effectively the averaged effect of the plasma environment on atomic spectra. The
results are in agreement with other reported ones.

摘要: Dietary therapy is the mainstay of treatment for diabetes. This study examined
the effect of a low glycemic index (GI) multi-nutrient supplement, consumed in place
of breakfast, on glycemic control in patients with type 2 diabetes mellitus (T2DM).
A total of 71 participants were randomized at a 2: 1 ratio into either a breakfast
replacement group or a normal breakfast group for a 12-week interventional study.
The primary outcome measure was change in hemoglobin A1c (HbA1c). Nutrition status
and somatometry were studied as secondary outcomes. The breakfast replacement group
displayed a -0.2% absolute reduction in HbA1c (95% CI (confidence interval), -0.38%
to -0.07%, p = 0.004), while the HbA1c of the control group increased 0.3% (95%
CI, 0.1% to 0.5%, p = 0.005). The baseline Mini Nutritional Assessment score for
both groups was 26.0 and no significant changes occurred following intervention.
However, there was a statistically significant difference in body mass index between
the treatment and control groups (p = 0.032) due to the weight gain in the control
group (increased 0.5 kg, 95% CI was 0.2 to 0.9, p = 0.007). These data suggest that
breakfast replacement with a low GI multi-nutrient supplement can improve glycemic
and weight control in T2DM.

摘要: Influences of two collective noises, i.e., the dephasing noise and the
rotating noise, on quantum correlations in Werner states are considered in this
note. It is found that the collective noises do not alter the correlations as far
as quantum discord and geometry discord as quantifiers are concerned.
Alternatively, quantum correlations in Werner states are robust against the noises.

摘要: A potentially practical scheme is proposed to realize optical quantum
simulation of artificial Abelian gauge field in a scalable architecture consisting
of cold atomic ensembles with optical cavities. In the present model, the collective
excitations of cold atomic ensembles can be converted to the bosonic modes within
the low-excitation limit, where the structure of two-dimension (2D) square
plaquette enables the polaritons to move like a charged particle subjected to an
external magnetic field. We find that the energy spectrum of this hybrid system
exhibits a shape of Hofstadter buttery. Our work provides a different perspective
to the quantum simulation of condensed matter and many-body physics in the context
of cavity quantum electrodynamics. The experimental feasibility are justified using
the existing techniques.

摘要: We propose a potentially practical scheme for generating the controllable
photonic Fock state in a cavity by using the bichromatic adiabatic passage technique
in the atom-cavity-laser system under dissipative environment. By numerically
simulating the quantum dynamics of the whole system, we demonstrate quantitatively
that the maximal probabilities of the Fock state can be achieved by elaborately
adjusting the peak amplitudes of the laser's Rabi frequency and the detuning between
the laser frequency and the atomic transition frequency. In addition, we have also
shown that the atomic and cavity dissipations play different roles in the
preparation of the Fock state inside the cavity. The experimental feasibility and
challenge are justified using currently available technology. (C) 2014 Optical

the initial authentication key for reuse. The security of the proposed scheme is
extensively analyzed and accordingly confirmed in the case of general individual
attacks. The present scheme owns high efficiency due to the use of single-particle
states in a two-way quantum channel. Moreover, the scheme is economical and feasible

摘要: A hybrid quantum architecture was proposed to engineer a
localization-delocalization phase transition of light in a two-dimension square
lattices of superconducting coplanar waveguide resonators, which are
interconnected by current-biased Josephson junction phase qubits. We find that the
competition between the on-site repulsion and the nonlocal photonic hopping leads
to the Mott insulator-superfluid transition. By using the mean-field approach and
the quantum master equation, the phase boundary between these two different phases
could be obtained when the dissipative effects of superconducting resonators and
phase qubit are considered. The good tunability of the effective on-site repulsion
and photon-hopping strengths enable quantum simulation on condensed matter physics
and many-body models using such a superconducting resonator lattice system. The
experimental feasibility is discussed using the currently available technology in
the circuit QED.

摘要: Wet deposition is an effective and important mechanism for removal of
atmospheric pollutants, particularly in urban regions. To examine the effectiveness
of natural and anthropogenic factors in such removal mechanisms, we conducted a
study in Guangzhou, a mega metropolitan center in South China. Rainwater and dry
particle deposition samples were simultaneously collected from Guangzhou during
the entire year of 2010, and analyzed for polybrominated diphenyl ethers (PBDEs),
a group of pollutants mainly derived from industrial and household consumer
products. Concentrations of SPBDE (sum of the 21 congeners of PBDEs) and BDE-209
in wet deposition samples ranged from 0.11 to 640 (average: 23 +/- 36 ng L-1) and
0.071 to 420 (average: 20 +/- 31 ng L-1), respectively. Assessed by conditional
inference tree, particulate matter was recognized as the most important factor
controlling concentration levels of PBDEs. The combined wet and dry deposition flux
of SPBDE (1.4 (+/-1.2) x 10(4) ng m(-2) quarter(-1)) in the first quarter of 2010
was not significantly different from that (1.3 (+/-0.46) x 10(4) ng m(-2)
quarter(-1)) in the fourth quarter, indicating that source control measures
implemented by local governments for the 16th Asian Games and 10th Asian Para Games
(held in November and December 2010, respectively) were ineffective in reducing
the loadings of atmospheric PBDEs. In addition, the lower removal efficiency of
SPBDE was found in the fourth quarter compared to other quarters. This result
suggested that rain interventions conducted to maintain clear weather conditions
for the Asian Games turned out to lower the efficacy for removal of PBDEs by wet
deposition.

摘要: The invasion of Ambrosia artemisiifolia and Ambrosia trifida from their native
range to occupy large areas in China has raised considerable concern. Using the
maximum entropy (Maxent) method, we developed models for each Ambrosia species,
based on occurrence records from both native ranges (North America) and their
invaded ranges (e.g. northern and south-western Europe) to predict the availability
and distribution of suitable habitats for these two species in China. For each
species, we also assessed potential shifts in habitat suitability for the year 2050,
using three general circulation models (GCMs) and two emission scenarios. Elevation
and average mean precipitation in October contributed most to model development
for both species. Potential distribution projections under future climatic change
scenarios suggested an averaged percentage of suitable area (2.21%) and habitat
gain (1.49%) in A.artemisiifolia distribution, with further expansion to
environmentally favourable locations in south-east coastal regions, northern
Taiwan and the Beijing-Tianjin-Tangshan area in northern China. Future predicted
percentage of suitable area for A.trifida was 0.03% with a very limited suitable
habitat gain of <1% although this species had the potential to continue to spread
in northern China. Our findings suggest that management priorities should be focused
on A.artemisiifolia, whilst effective control strategies for A.trifida may be
optimised by concentrating efforts on those relatively fewer regions of China where
the species is currently abundant.

摘要: Broilers in four groups were fed a basal diet supplemented with 60 mg/kg zinc
oxide (60-ZnO; control), or 20, 60, or 100 mg/kg ZnO nanoparticles (20-, 60-, and
100-nano-ZnO, respectively). Compared with the controls, after 14 days, birds in
the 20- and 60-nano-ZnO groups had significantly greater weight gains and better
feed conversion ratios. However, the body weight of birds in the 100-nano-ZnO group
was dramatically reduced after 28 days. Relative to the control group, the total
antioxidant capability (T-AOC) in serum and liver tissue was significantly higher
in the 20-nano-ZnO group at all time points and also significantly higher in the
60- and 100-nano-ZnO groups in serum on days 28 and 35 and in liver tissues on days
21 and 28. Compared with the controls, the activity of copper-zinc superoxide
dismutase (Cu-Zn-SOD) was significantly greater in the 60- and 100-nano-ZnO groups
in serum on days 28 and 35 and in liver tissues after 21 days. Catalase activity
in serum samples was significantly higher in the 20- and 60-nano-ZnO groups relative
to the control and 100-nano-ZnO birds, but catalase activity in liver tissue was
not affected by different nano-ZnO levels. Malondialdehyde content in serum and
liver tissues was significantly reduced in the 20-, 60-, and 100-nano-ZnO groups
compared with that in the control group at all time points except day 42. Taken
together, our data indicate that appropriate concentration of dietary ZnO
nanoparticles improves growth performance and antioxidative capabilities in
broilers, and 20 mg/kg nano-ZnO is the optimal concentration.

摘要: First, the Cauchy problem for KdV equation with 2n +1 order dispersion is
studied, and the local well-posedness result for the initial data in Sobolev spaces
H-S (R) with s > -n + 1/4 is established via the Fourier restriction norm method.
Second, we prove 4 that the KdV equation with 2n + 1 order dispersion is ill-posed
for the initial data in H-s (R) with s < -n + 1/4, n >= 2, n is an element of N+
if the flow map is C-2 differentiable at zero form H-s(R) to C([0,T]; H-s(R)).
Finally, we obtain the sharp regularity requirement for the KdV equation with 2n
+ 1 order dispersion s > -n + 1/4. (C) 2014 Elsevier Inc. All rights reserved.

摘要: The global asymptotical synchronization problem is discussed for a general
class of uncertain stochastic discrete-time neural networks with time delay in this
paper. Time delays include time-varying delay and distributed delay. Based on the
drive-response concept and the Lyapunov stability theorem, a linear matrix
inequality (LMI) approach is given to establish sufficient conditions under which
the considered neural networks are globally asymptotically synchronized in the mean
square. Therefore, the global asymptotical synchronization of the stochastic
discrete-time neural networks can easily be checked by utilizing the numerically
efficient Matlab LMI toolbox. Moreover, the obtained results are dependent not only
on the lower bound but also on the upper bound of the time-varying delays, that
is, they are delay-dependent. And finally, a simulation example is given to
illustrate the effectiveness of the proposed synchronization scheme.

摘要: A design is proposed for scalable solid-state quantum computing, which is
based on collectively enhanced magnetic coupling between nitrogen-vacancy center
ensembles and superconducting transmission line resonators interconnected by
current-biased Josephson junction superconducting phase qubit. In this hybrid
system, we realize distant multi-qubit controlled phase gate operations and
generate distant multi-qubit entangled W-like states, being indispensable resource
to quantum computation. Our proposed architecture consists of solid-state spin
ensembles and circuit QED, and could achieve quantum computing in a solid-state
environment with high-fidelity and scalable way. The experimental feasibility is
discussed, and the implementation efficiency is demonstrated numerically.

摘要: Tripartite remote sharing of any single-qubit operation with two asymmetric
three-qubit W states is amply treated. Five schemes are put forward with the W states
in five different entanglement structures corresponding to five different
distributions of two identical qubit trios in three locations. For all schemes,
two features about the security and the agent symmetry are analyzed and confirmed.
Moreover, resource consumption, necessary-operation complexity, success
probability and efficiency are also worked out and compared mutually. For all
schemes, quantum resource consumption and necessary-operation complexity are same.
The last scheme needs to cost two additional classical bits than the former four
schemes. Nonetheless, the last scheme is deterministic and has the highest
efficiency in contrast to the other four probabilistic schemes with lower
efficiencies. Through some analyses, it is found that both success probability and
intrinsic efficiency of each scheme are completely determined by the corresponding
entanglement structure of the two W states. The underlying physics of this feature
is revealed. In addition, the implementation feasibility of all the schemes is
analyzed and thus confirmed according to the current experimental techniques.

摘要: Apoptosis is an early event of steatohepatitis in non-alcoholic fatty liver
disease (NAFLD), and an increase in oxidative stress induced by hyperglycemia has
been linked to an acceleration of apoptosis in hepatocytes.
Cyanidin-3-O-beta-glucoside (C3G), a classic anthocyanin, has been reported to
reduce oxidative stress and attenuate non-alcoholic steatohepatitis in mice. In
this study, we evaluated the toxicity of high glucose in primary hepatocytes of
mice fed with a high fat diet and amelioration of this toxicity by C3G. Incubation
of hepatocytes with 35 mM glucose for 12 h resulted in a significant decrease in
cell viability and increase in apoptotic cell death. Furthermore,
hyperglycemia-induced mitochondrial depolarization was accompanied by the release
of cytochrome c and altered expression of Bax and BcI-2, suggesting a
mitochondria-mediated apoptotic mode of cell death. Pre-incubation with 50 mu M
C3G induced changes associated with better cell survival and function, including
a reduction in reactive species generation, improvement of mitochondrial membrane
potential, inactivation of caspase-3 and 9, and down-regulation of the
pro-apoptotic Bax protein. We further investigated the role of the
phosphatidylinositol 3-kinase (PI3K)/Akt and mitogen-activated protein kinases
(MAPKs) pathways with respect to the anti-apoptotic action of C3G, and our results
showed that C3G could activate Akt. Additionally, C3G inactivated c-Jun N-terminal
protein kinase (JNK), but not extracellular signal-regulated kinase or p38 MAPK,
in glucose-stressed cells. Interestingly, JNK inhibitor enhanced the protective
effect of C3G on cell survival. Our results suggest that anthocyanin C3G may exhibit
hepatoprotective potential against NAFLD by promoting functional integrity and
survival of hepatocytes. (C) 2014 Elsevier Inc. All rights reserved.

摘要: The chemical differences of panax notoginseng before and after processing were
analyzed by Fourier transform Infrared spectroscopy (FTIR) combined with
two-dimensionalcorrelation spectroscopy (2D-IR). Compared with conventional IR
spectra of the samples, the FTIR spectra of panax notoginseng and its processed
products were similar in the range of 1 200 similar to 400 cm(-1). The difference
was that prepared panax notoginseng had strong and characteristic peaks at 2 925,
2 855, 1 746, 1 460, 1 376 and 1 158 cm-1, which all arose from the characteristic
vibration of peanut oil. This was because there was some peanut oil left in the
panax notoginseng, when panax notoginseng after processing. Obvious differences
were observed between 2D-IR spectra of them, in the range of 1 400 similar to 1
700 cm(-1), there was only one auto peaks at 1 650 cm(-1) in the spectra of panax
notoginseng, but there were auto peaks at 1 469 and 1 640 cm(-1) in the spectra
of prepared panax notoginseng. In the range of 1 400 similar to 1 700 cm(-1), the
2D-IR spectra of panax notoginseng and its processed product present characterstic
peaks at 1 139 (1 137), 1 194(1 196), 1 121(1 221) cm respectively, but the relative
intensities of auto peaks were changed. For example, auto peak around 1 139 cm(-1)
was enhanced, but auto peak around 1 194 cm(-1) was weakened. The results of 2D-IR
correlation spectroscopy indicated the decomposition of flavonoids, saccharides
and saponins. This method can track dynamically the processing-procedure of panax
notoginseng and reveal the main tansformations, so it can explain the pharmacology
of panax notoginseng and its processed product by FTIR and 2D-IR.

摘要: Werner derivatives are a special kind of mixing states transformed from Werner
states by unitary operations (Hiroshima and Ishizaka in Phys Rev A 62:044302, 2000).
In this paper, the inherent quantum correlations in Werner derivatives are
quantified by two different quantifiers, i.e., quantum discord and geometric
discord. Different analytic expressions of the two discords in Werner derivatives
are derived out. Some distinct features of the discords and their underlying physics
are exposed via discussions and analyses. Moreover, it is found that the amount
of quantum correlations quantified by either quantifier in each derivative cannot
exceed that in the original Werner state. In other words, no unitary operation can
increase quantum correlation in a Werner state as far as the two quantifiers are
concerned.

摘要: Two three-party schemes are put forward for sharing quantum operations on a
remote qutrit with local operation and classical communication as well as shared
entanglements. The first scheme uses a two-qutrit and three-qutrit non-maximally
entangled states as quantum channels, while the second replaces the three-qutrit
non-maximally entangled state with a two-qutrit. Both schemes are treated and
compared from the four aspects of quantum and classical resource consumption,
necessary-operation complexity, success probability and efficiency. It is found
that the latter is overall more optimal than the former as far as a restricted set
of operations is concerned. In addition, comparisons of both schemes with other
four relevant ones are also made to show their two features, including degree
generalization and channel-state generalization. Furthermore, some concrete
discussions on both schemes are made to expose their important features of security,
symmetry and experimental feasibility. Particularly, it is revealed that the
success probabilities and intrinsic efficiencies in both schemes are completely
determined by the shared entanglement.

摘要: An adaptive synchronization of uncertain chaotic system is presented using
partition of unity method. First, the uncertainties of chaotic systems are
approximate by the linear combination of partition of unity. Subsequently, the
sliding mode adaptive controllers are proposed for synchronization of the uncertain
chaotic systems. The proposed approach offers a systematic design procedure for
adaptive synchronization of a class of uncertain chaotic system in the chaos
research literature. We also illustrate examples of chaotic systems such as Chen
and Lorenz chaotic systems to show the effectiveness of the approach.

摘要: This work focused on the effect of glycosylation on the gelation ability of
-conglycinin induced by microbial transglutaminase (MTGase). Rheological results
indicated that the gels of -conglycinin-dextran conjugate products exhibited higher
G value (172.2 +/- 8.6Pa) compared with those of dry-heated -conglycinin (75.2 +/5.1Pa), -conglycinin (53.3 +/- 4.0Pa) and -conglycinin-dextran mixture (38.6 +/2.6Pa) after 4h incubation with MTGase. The gels prepared from -conglycinin-dextran
conjugate products had higher hardness, fracturability, springiness and
cohesiveness values determined by textural profile analysis. The turbidity of
-conglycinin-dextran conjugate products solution incubated with MTGase increased
faster than those of the other three protein samples. The conjugated dextran in
-conglycinin-dextran conjugate products could inhibit extensive protein-protein
interactions which might result in the formation of more ordered and stronger gel
network structures during MTGase cross-linking process. A compact and homogeneous
gel networks in -conglycinin-dextran conjugate products gels were also observed
by scanning electron microscopy.

摘要: In this paper, on the basis of the Laypunov stability and the cascade
synchronization approach, an effectual scroll controller and improving cascade
synchronization approach are derived. The chaotic attractor can be displayed to
be lopsided, till to be 1-scroll and periodic via the different scroll controller.
And the proposed synchronization technique is applied to the new system, which the
synchronization controller obtained by improving cascade method and adaptive
functions. Numerical results are used to verify the effectiveness of the scheme.

摘要: Reaction of CdCl2 with mixed-ligands of imidazole-4,5-dicarboxylic acid
(H3IDC) and 1,4-benzenedicarboxylic acid (H2BDC) under hydrothermal condition,
yielded a new 3D cadmium(II) coordination polymer of [Cd-2(HIDC)(BDC)(H2O)](n) (1),
which was structurally characterized by elemental analysis, infrared spectroscopy,
powder X-ray diffraction, and single-crystal X-ray diffraction. The result of
single-crystal X-ray diffraction analysis reveals that complex 1 crystallizes in
the monoclinic crystal system with P2(1)/n, space group, a=0.884 34 (2) nm, b=1.577
50(3) nm, c=1.071 58(3) nm, beta=97.227(2), V=1.483 03(6) nm(3), Z=4, D-c=2.513
g.cm(-3), F(000)=1 072, the final R-1=0.031 5, wR(2)=0.053 1 for 2 674 observed
reflections with I>2 sigma-(I). In complex 1, the interconnection of Cd(II) ions
by carboxylate oxygen atoms from BDC2- ligands result in an infinite 10 polymeric
chain of {[Cd-2(CO2)](2)(CO2)(2)}(n) along a axis. The polymeric chains are further
connected by HIDC2- and BDC2- bridging ligands to form a complicated 3D
metal-organic framework architecture. Furthermore, its thermal stability and
luminescent property at room temperature in the solid state were also investigated.

摘要: Using a bifurcation method and a numerical simulation approach of dynamical
systems, we study the generalized KP-MEW(2, 2) equation (u(t) + (u(2))(x) +
(u(2))(xxt))(x) + u(yy) = 0. Two types of bounded traveling waves are found, that
is, a compacton-like wave and a kink-like wave. The planar graphs of the
compacton-like and kink-like waves are simulated using the software Maple. Exact
implicit or parameter expressions of these solutions are given.

摘要: Microstructures, phase structures, and dielectric properties of Li and Sc
co-doped NiO ceramics were systematically investigated. A high epsilon' (similar
to 10(4)) is observed in a wide temperature (200-420 K) and frequency (100-10 kHz)
range. The increase of epsilon' with Li concentration is related to the increase
of grain size. With increasing temperature, epsilon' enhances and the epsilon
aEuro(3) peak shifts to higher frequency, indicating a thermally activated
relaxation process. The activation energy for relaxation is nearly comparable to
that for grain conduction, implying the polarization process depends on the
conducting of the charge in the grain interior. Complex impedance spectroscopy
analysis shows the dielectric behavior is attributed to the boundary-layer
capacitor mechanism and existing huge polarization.

摘要: A series of Sb-doped CaCu3Ti4O12 ceramics were fabricated by the conventional
solid state method, and their crystalline structures, microstructures and
dielectric properties were investigated systematically. All the ceramic samples
exhibited perovskite-related structures in space group Im . The grain size decreased
slightly as Sb concentration increased; whereas the dielectric permittivity of the
ceramics increased slightly. The giant dielectric response was considered to be
closely related with a reduction in the potential barrier height at grain boundaries
(GBs). The activation energy for the dc conduction process is comparable to that
for conduction at GBs, indicating that the dc conduction process is associated with
the electrical response of GBs.

摘要: Linear discriminant analysis (LDA) is one of the most popular supervised
feature extraction techniques used in machine learning and pattern classification.
However, LDA only captures global geometrical structure information of the data
and ignores the geometrical structure information of local data points. Though many
articles have been published to address this issue, most of them are incomplete
in the sense that only part of the local information is used. We show here that
there are total three kinds of local information, namely, local similarity
information, local intra-class pattern variation, and local interclass pattern
variation. We first propose a new method called enhanced within-class LDA (EWLDA)
algorithm to incorporate the local similarity information, and then propose a
complete framework called complete global-local LDA (CGLDA) algorithm to
incorporate all these three kinds of local information. Experimental results on
two image databases demonstrate the effectiveness of our algorithms. (C) 2013

摘要: Many practical engineering applications require various types of fuzzy logic
systems (FLSs) to design adaptive controllers for nonlinear systems with
uncertainties. In this article, we will consider a fundamental theoretical
question: is it possible to find a unified adaptive control design method suited
to various types of FLSs? In order to solve this problem, we will introduce scalers
and saturators at the input and output terminals of FLSs to form the extended FLSs
(EFLS). The scalers and saturators have adjustable parameters. By designing the
updated laws of these parameters and the estimate values of the fuzzy approximate
accuracies, stable adaptive fuzzy controllers can be realised for a class of
nonlinear systems with unknown homogeneous drift functions and gains. The proposed
design method is only dependent on the outputs of EFLS and the above updated laws,
thus increasing its adaptability. The fuzzy control scheme introduced in this
article is suitable for all fuzzy systems with or without fuzzy rules. Simulations
will also be used to show the validity of the method proposed in this article.

摘要: Obestatin, originally identified and purified from rat stomach extracts, was
reported to bind to orphan G protein-coupled receptor, GPR39, and inhibit appetite
and gastric motility. This study was conducted to investigate the effects of porcine
obestatin on proliferation, differentiation and apoptosis of porcine preadipocytes
isolated from subcutaneous fat of piglets. At indicated times of culture, morphology
of preadipocytes and accumulated lipid droplets within the cells were identified
by invert microscope. After treating with obestatin (0, 0.1, 1, 10 and 100 nM),
cell proliferation was measured by MTT method and protein expression of
CCAAT/enhancer binding protein-alpha (C/EBP alpha), peroxisome
proliferator-activated receptor-gamma (PPAR gamma), Caspase-7 and Caspase-9 was
determined by Western Blot, mRNA expression of GPR39 and Caspase-3 was analyzed
by RT-PCR, and the activity of Caspase-3 was measured by spectrophotometric method.
The results showed that obestatin had no effect on GPR39 expression, while promotes
the optical density (OD) value of cells, enhanced protein expression of PPAR gamma
and C/EBPa, decreased mRNA expression and activity of Caspase-3, and inhibited
protein expression of Caspase-7 and Caspase-9 in a dose-dependent manner. These
results suggested that obestatin enhance proliferation and differentiation of
preadipocytes promoting PPAR gamma and C/EBPa expression, and inhibiting
preadipocyte apoptosis by decreasing expression of Caspase-3, Caspase-7 and
Caspase-9. (C) 2013 Elsevier Masson SAS. All rights reserved.

摘要: Chiral analysis is one of the most important/challenging analytical tasks due
to the necessity for differentiation of very slight differences in the molecular
configurations between chiral isomers. It consists of two processes, chiral
recognition and signal transduction. Quartz crystal microbalance (QCM) holds a
great promise for the next-generation sensors, due to its remarkable mass
sensitivity, fast response, capable of online detection and low cost. It has been
the focus of academic and practical research on chiral analysis during the last
two decades. This review provides a detailed overview of recent advances made in
chiral analysis based on QCM detection with regard to the recognition elements,
which include synthetic macromolecules, molecular imprinting polymers (MIPs),
proteins, amino acids and their derivatives, etc. The prospects of using QCM for
chiral analysis are also put forward.

摘要: A general similarity projective solution to the generalized Korteweg-de Vries
(KdV) system with varying coefficients is derived with the aid of direct similarity
projective approach. All the allowed exact solutions of the standard KdV equation
can be converted into the corresponding exact solutions of the generalized KdV
system. In terms of the known exact solution of the KdV equation, some typical
localized excitations with self-similar behaviors and similaritons are revealed
by prescribing appropriate system parameters.

摘要: Objective: Oxidative stress and inflammation are involved in the pathogenesis
of non-alcoholic fatty liver disease (NAFLD). Bayberries contain high levels of
polyphenols that possess anti-oxidative and anti-inflammatory properties in vitro.
The purpose of this study was to investigate whether the consumption of bayberry
juice beneficially alters the levels of oxidative, inflammatory, and apoptotic
biomarkers in young individuals with features of NAFLD.
Methods: In this randomized, placebo-controlled, double-blind, crossover study,
44 participants (ages 18-25 y) were given 250 mL of either bayberry juice or placebo
twice daily for 4 wk. Several anthropometric characteristics were measured, and
fasting blood samples were drawn before and after each intervention period. The
levels of plasma glucose, insulin, lipids, and some NAFLD-related biomarkers were
determined.
Results: No significant effects on the anthropometric parameters and the
homeostasis model assessment for insulin resistance were observed. Compared with
placebo, the consumption of bayberry juice significantly decreased the plasma
levels of protein carbonyl groups (P = 0.038), tumor necrosis factor-a (P < 0.001),
and interleukin-8 (P = 0.022). The apoptosis markers analysis revealed significant
differences between the treatment and the placebo in the levels of tissue
polypeptide-specific antigen (P < 0.001) and cytokeratin-18 fragment M30 (P <
0.001).
Conclusion: The consumption of bayberry juice for a period of 4 wk can protect
against NAFLD in young adults by improving the plasma antioxidant status and
inhibiting the inflammatory and apoptotic responses that are involved in this
disease. (C) 2014 Elsevier Inc. All rights reserved.

摘要: Hydrophobic coatings for practical applications demand good durability of
hydrophobicity and excellent adhesion. Therefore, the preparation of crosslinked
crystalline polymers with perfluoroalkyl side-chains and long alkyl side-chains
were proposed. In this paper, the influence of the crosslinking on the
crystallization of fluorinated acrylate copolymers was investigated through
experimental and molecular dynamic simulation results. According to the FT-IR
spectroscopy, XRD data and DSC curves, P(SA-co-HEMA-co-FOEMA) was amorphous, while
P(SA-co-FOEMA) and the cured resin formed crystalline polymers with hexagonal
packing of alkyl side-chains, and the degree of crystallinity in the cured resin
is larger than that in P(SA-co-FOEMA). These phenomenons were further interpreted
through the snapshots of the equilibrated systems, the radial distribution
function, and the concentration profiles. Intramolecular hydrogen bonds and
arrangement of main-chains, corresponding to the embedding of N3300, were
considered to contribute to these phenomenons. These findings could be expanded
to other comb-shape crystalline polymers for preparing functional surfaces and
smart materials.

摘要: Porous magnetic polymer microspheres (PMPMs) were used as an adsorbent to
removal of methyl violet (MV) from wastewater. Ethanol/water co-solvent mixtures
in combination with various inorganic salts were used as eluents to regenerate
PMPMs. The desorption capacity of the eluents were systematically investigated.
The results showed that when ethanol/water co-solvents were used as the eluent,
the desorption efficiency increased with the ethanol concentration. Incorporation
of inorganic salts into the co-solvents greatly improved the desorption efficiency
of the eluents. Among the eluents, a mixture of ethanol/water (8/2, v/v) in
combination with 0.1M KCl exhibited excellent ability for recovering cationic dyes
and regenerating PMPMs, which was again demonstrated during treatment of wastewater
containing cationic golden yellow. Furthermore, the adsorption kinetics of methyl
violet by PMPMs was also studied. It was found that the adsorption capacity depended
on the initial concentration of dyes, and the pseudo-second-order model was more
suitable to describe adsorption kinetics of methyl violet than the
pseudo-first-order model.

摘要: In this paper, we investigate the modified Boussinesq equation
u(tt) - u(xx) - epsilon u(xxxx) - 3(u(2))(xx) + 3(u(2)u(x))(x) = 0.
Firstly, we give a property of the solutions of the equation, that is, if 1 + u(x,
t) is a solution, so is 1 - u(x, t). Secondly, by using the bifurcation method of
dynamical systems we obtain some explicit expressions of solutions for the equation,
which include kink-shaped solutions, blow-up solutions, periodic blow-up solutions
and solitary wave solutions. Some previous results are extended.

摘要: By a pH value controlled synthesis strategy, hydrothermal reactions of Cd(NO3)(2)center
dot 4H(2)O with mixed-ligands of 5-amino-tetrazole (Hatz) and 1,2,4,5-benzenetetracarboxylic
acid (H(4)btec) yielded two 3D cadmium(II) coordination polymers (CPs) of
{K[Cd-2(atz)(btec)(H2O)(2)]}(n) (1) and [Cd-3(OH)(atz)(btec)(H2O)(2)](n)center dot nH(2)O
(2). Their structures were determined by elemental analysis (EA), infrared spectra (IR),
thermogravimetric analysis (TGA) and single-crystal/powder X-ray diffraction. The results reveal
that both 1 and 2 are 3D architectures. In 1, the Cd(II) ions are connected together by mu(2)-atz
and mu(6)-btec(4-), generating a rare (4,6)-connected anion framework. The anti-cation K+ ions
locate the micropores and weakly interact with the carboxyl oxygen of the mu(6)-btec(4-) ligands.
In 2, six Cd(II) ions are linked together through two mu(3)-OH- and two mu(3)-atz(-) to form a
[Cd-6(mu(3)-OH)(2)(mu(3)-atz)(2)](8+) unit, which is further connected with other equivalent
units by mu(9)-btec(4-) spacers, resulting in a rare (5,10)-connected porous framework. The
photoluminescent investigation illustrates that 1 and 2 show strong emissions at 470 and 457 nm
upon excitation at 350 and 370 nm, respectively.

摘要: (K0.5Na0.5)(1-x)LixNb0.84Ta0.1Sb0.06O3 (KNLNTS) lead free ceramics with different
Li concentration were fabricated by conventional solid-state reaction method. By increasing Li
ions in KNLNTS, the grains grow up and the crystal structure changes from orthorhombic to
tetragonal. When 0.03 <= x <= 0.05, the ceramics structure lays in PPT region. Polarization
versus electric field (P-E) hysteresis loops at room temperature show good ferroelectric properties
and the remnant polarization decreases by increasing Li content while coercive electric keeps
almost unchanged. In PPT region, taking x = 0.04 as an example, the sample shows excellent
dielectric properties: the dielectric constant is 1159 and loss tangent is 0.04, while the
piezoelectric constant d(33) is 245 pC/N and kp is 0.44 at room temperature, it is promising for
(K0.5Na0.5)(1-x)LixNb0.84Ta0.1Sb0.06O3 with 4 at. % Li to substitute PZT. (C) 2014
