Abstract: Several Markov chain methods are available for sampling from a posterior
distribution. Two important examples are the Gibbs sampler and the Metropolis algorithm.
In addition, several strategies are available for constructing hybrid algorithms. This paper
outlines some of the basic methods and strategies and discusses some related theoretical
and practical issues. On the theoretical side, results from the theory of general state space
Markov chains can be used to obtain convergence rates, laws of large numbers and central
limit theorems for estimates obtained from Markov chain methods. These theoretical
results can be used to guide the construction of more efficient algorithms. For the
practical use of Markov chain methods, standard simulation methodology provides
several Variance reduction techniques and also gives guidance on the choice of sample
size and allocation.

Title: ANALYSIS OF POPULATION GENETIC-STRUCTURE WITH RAPD MARKERS
Source: MOLECULAR ECOLOGY, 3 (2): 91-99 APR 1994《分子生态学》英国
Abstract: Recent advances in the application of the polymerase chain reaction make it
possible to score individuals at a large number of loci. The RAPD (random amplified
polymorphic DNA) method is one such technique that has attracted widespread interest.
The analysis of population structure with RAPD data is hampered by the lack of complete
genotypic information resulting from dominance, since this enhances the sampling
variance associated with single loci as well as induces bias in parameter estimation. We
present estimators for several population-genetic parameters (gene and genotype
frequencies, within- and between-population heterozygosities, degree of inbreeding and
population subdivision, and degree of individual relatedness) along with expressions for
their sampling variances. Although completely unbiased estimators do not appear to be
possible with RAPDs, several steps are suggested that will insure that the bias in
parameter estimates is negligible. To achieve the same degree of statistical power, on the
order of 2 to 10 times more individuals need to be sampled per locus when dominant
markers are relied upon, as compared to codominant (RFLP, isozyme) markers. Moreover,
to avoid bias in parameter estimation, the marker alleles for most of these loci should be
in relatively low frequency. Due to the need for pruning loci with low-frequency null
alleles, more loci also need to be sampled with RAPDs than with more conventional
markers, and sole problems of bias cannot be completely eliminated.

Abstract: In this study, we describe a psychobiological model of the structure and
development of personality that accounts for dimensions of both temperament and
character. Previous research has confirmed four dimensions of temperament: novelty
seeking, harm avoidance, reward dependence, and persistence, which are independently
heritable, manifest early in life, and involve preconceptual biases in perceptual memory
and habit formation. For the first time, we describe three dimensions of character that
mature in adulthood and influence personal and social effectiveness by insight learning
about self-concepts. Self-concepts vary according to the extent to which a person
identifies the self as (1) an autonomous individual, (2) an integral part of humanity, and (3)
an integral part of the universe as a whole. Each aspect of self-concept corresponds to one
of three character dimensions called self-directedness, cooperativeness, and
self-transcendence, respectively. We also describe the conceptual background and
development of a self-report measure of these dimensions, the Temperament and
Character Inventory. Data on 300 individuals from the general population support the
reliability and structure of these seven personality dimensions. We discuss the
implications for studies of information processing, inheritance, development, diagnosis,
and treatment.

• Source: JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION, 90 (432):
1200-1224 DEC 1995 《美国统计学会志》 被引用 429 次
• Abstract: We attempt to recover a function of unknown smoothness from noisy sampled
data. We introduce a procedure, SureShrink, that suppresses noise by thresholding the
empirical wavelet coefficients. The thresholding is adaptive: A threshold level is assigned
to each dyadic resolution level by the principle of minimizing the Stein unbiased estimate
of risk (Sure) for threshold estimates. The computational effort of the overall procedure is
order N.log(N) as a function of the sample size N. SureShrink is smoothness adaptive: If
the unknown function contains jumps, then the reconstruction (essentially) does also; if
the unknown function has a smooth piece, then the reconstruction is (essentially) as
smooth as the mother wavelet will allow. The procedure is in a sense optimally
smoothness adaptive: It is near minimax simultaneously over a whole interval of the
Besov scale; the size of this interval depends on the choice of mother wavelet. We know
from a previous paper by the authors that traditional smoothing methods-kernels, splines,
and orthogonal series estimates-even with optimal choices of the smoothing parameter,
would be unable to perform in a near-minimax way over many spaces in the Besov scale.
Examples of SureShrink are given. The advantages of the method are particularly evident
when the underlying function has jump discontinuities on a smooth background

• Abstract: Bcl-2 protein is able to repress a number of apoptotic death programs. To
investigate the mechanism of Bcl-2's effect, we examined whether Bcl-2 interacted with
other proteins. We identified an associated 21 kd protein partner, Bax, that has extensive
amino acid homology with Bcl-2, focused within highly conserved domains I and II. Bax
is encoded by six exons and demonstrates a complex pattern of alternative RNA splicing
that predicts a 21 kd membrane (alpha) and two forms of cytosolic protein (beta and
gamma). Bax homodimerizes and forms heterodimers with Bcl-2 in vivo. Overexpressed
Bax accelerates apoptotic death induced by cytokine deprivation in an IL-3-dependent
cell line. Overexpressed Bax also counters the death repressor activity of Bcl-2. These
data suggest a model in which the ratio of Bcl-2 to Bax determines survival or death
following an apoptotic stimulus.

• Abstract: For more than two decades the astrophysics community has depended on
opacity tables produced at Los Alamos. In the present work we offer new radiative
Rosseland mean opacity tables calculated with the OPAL code developed independently
at LLNL. We give extensive results for the recent Anders-Grevesse mixture which allow
accurate interpolation in temperature, density, hydrogen mass fraction, as well as metal
mass fraction. The tables are organized differently from previous work. Instead of rows
and columns of constant temperature and density, we use temperature and follow tracks of
constant R, where R = density/(temperature)3. The range of R and temperature are such
as to cover typical stellar conditions from the interior through the envelope and the hotter
atmospheres. Cool atmospheres are not considered since photoabsorption by molecules is
neglected. Only radiative processes are taken into account so that electron conduction is
not included. For comparison purposes we present some opacity tables for the Ross-Aller
and Cox-Tabor metal abundances. Although in many regions the OPAL opacities are
similar to previous work, large differences are reported. For example, factors of 2-3
opacity enhancements are found in stellar envelop conditions.

Abstract: With the aim to provide observational constraints on the evolution of the
galactic disk, we have derived abundances of 0, Na, Mg, Al, Si, Ca, Ti, Fe, Ni, Y, Zr, Ba
and Nd, as well as individual photometric ages, for 189 nearby field F and G disk dwarfs.
The galactic orbital properties of all stars have been derived from accurate kinematic data,
enabling estimates to be made of the distances from the galactic center of the
stars‘ birthplaces. 结构式摘要
Our extensive high resolution, high S/N, spectroscopic observations of carefully selected
northern and southern stars provide accurate equivalent widths of up to 86 unblended
absorption lines per star between 5000 and 9000 angstrom. The abundance analysis was
made with greatly improved theoretical LTE model atmospheres. Through the inclusion
of a great number of iron-peak element absorption lines the model fluxes reproduce the
observed UV and visual fluxes with good accuracy. A new theoretical calibration of T(eff)
as a function of Stromgren b - y for solar-type dwarfs has been established. The new
models and T(eff) scale are shown to yield good agreement between photometric and
spectroscopic measurements of effective temperatures and surface gravities, but the
photometrically derived very high overall metallicities for the most metal rich stars are
not supported by the spectroscopic analysis of weak spectral lines.

Abstract: This paper presents a detailed analysis of several hundred plant carbon

determined over the past 10 years. It demonstrates that the percentage increase in plant
growth produced by raising the air's CO2 content is generally not reduced by less than
optimal levels of light, water or soil nutrients, nor by high temperatures, salinity or
gaseous air pollution. More often than not, in fact, the data show the relative
growth-enhancing effects of atmospheric CO2 enrichment to be greatest when resource
limitations and environmental stresses are most severe.

SCI 被引用 296 次
Abstract: Markov chain Monte Carlo (MCMC) methods have been used extensively in
statistical physics over the last 40 years, in spatial statistics for the past 20 and in
Bayesian image analysis over the last decade. In the last five years, MCMC has been
introduced into significance testing, general Bayesian inference and maximum likelihood
estimation. This paper presents basic methodology of MCMC, emphasizing the
Bayesian paradigm, conditional probability and the intimate relationship with Markov
random fields in spatial statistics. Hastings algorithms are discussed, including Gibbs,
Metropolis and some other variations. Pairwise difference priors are described and are
used subsequently in three Bayesian applications, in each of which there is a pronounced
spatial or temporal aspect to the modeling. The examples involve logistic regression in
the presence of unobserved covariates and ordinal factors; the analysis of agricultural
field experiments, with adjustment for fertility gradients; and processing of

issues arise in each of these applications and in the Appendices. The paper lays particular
emphasis on the calculation of posterior probabilities and concurs with others in its view
that MCMC facilitates a fundamental breakthrough in applied Bayesian modeling.

time dependence of marine reservoir ages, and evaluate decadal vs. single-year C-14
results. Changes in oceanic deepwater circulation, especially for the 16,000-11,000 cal sp

primary interest, recapture or resighting rates that are nuisance parameters. 结构式摘要
This paper synthesizes, using a common framework, these recent developments together
with new ones, with an emphasis on flexibility in modeling, model selection, and the
analysis of multiple data sets. The effects on survival and capture rates of time, age, and
categorical variables characterizing the individuals (e.g., sex) can be considered, as well
as interactions between such effects. This "analysis of variance" philosophy emphasizes
the structure of the survival and capture process rather than the technical characteristics of
any particular model. The flexible array of models encompassed in this synthesis uses a
common notation. As a result of the great level of flexibility and relevance achieved, the
focus is changed from fitting a particular model to model building and model selection.

Abstract: The low-temperature formation of liquid-crystal-like arrays made up of
molecular complexes formed between molecular inorganic species and amphiphilic
organic molecules is a convenient approach for the synthesis of mesostructure materials.
This paper examines how the molecular shapes of covalent organosilanes, quaternary
ammonium surfactants, and mixed surfactants in various reaction conditions can be used
to synthesize silica-based mesophase configurations, MCM-41 (2d hexagonal, p6m),
MCM-48 (cubic Ia3d), MCM-50 (lamellar), SBA-1 (cubic Pm3n), SBA-2 (3d hexagonal
P6(3)/mmc), and SBA-3 (hexagonal p6m from acidic synthesis media). The structural
function of surfactants in mesophase formation can to a first approximation be related to
that of classical surfactants in water or other solvents with parallel roles for organic
additives. The effective surfactant ion pair packing parameter, g = V/alpha(0)l, remains a
useful molecular structure-directing index to characterize the geometry of the mesophase
products, and phase transitions may be viewed as a variation of g in the
liquid-crystal-Like solid phase. Solvent and cosolvent structure direction can be
effectively used by varying polarity, hydrophobic/hydrophilic properties and
functionalizing the surfactant molecule, for example with hydroxy group or variable
charge. Surfactants and synthesis conditions can be chosen and controlled to obtain
predicted silica-based mesophase products. A room-temperature synthesis of the
bicontinuous cubic phase, MCM-48, is presented. A low-temperature (100 degrees C) and
low-pH (7-10) treatment approach that can be used to give MCM-41 with high-quality,
large pores (up to 60 Angstrom), and pore volumes as large as 1.6 cm(3)/g is described.

Abstract: Background: This study presents estimates of lifetime and 12-month
prevalence of 14 DSM-III-R psychiatric disorders from the National Comorbidity Survey,
the first survey to administer a structured psychiatric interview to a national probability
sample in the United States. Methods: The DSM-III-R psychiatric disorders among
persons aged 15 to 54 years in the noninstitutionalized civilian population of the United
States were assessed with data collected by lay interviewers using a revised version of the
Composite International Diagnostic Interview. Results: Nearly 50% of respondents
reported at least one lifetime disorder, and close to 30% reported at least one 12-month
disorder. The most common disorders were major depressive episode, alcohol dependence,
social phobia, and simple phobia. More than half of all lifetime disorders occurred in the
14% of the population who had a history of three or more comorbid disorders. These
highly comorbid people also included the vast majority of people with severe disorders.
Less than 40% of those with a lifetime disorder had ever received professional treatment,

and less than 20% of those with a recent disorder had been in treatment during the past 12
months. Consistent with previous risk factor research, it was found that women had
elevated rates of affective disorders and anxiety disorders, that men had elevated rates of
substance use disorders and antisocial personality disorder, and that most disorders
declined with age and with higher socioeconomic status. Conclusions: The prevalence of
psychiatric disorders is greater than previously thought to be the case. Furthermore, this
morbidity is more highly concentrated than previously recognized in roughly one sixth of
the population who have a history of three or more comorbid disorders. This suggests that
the causes and consequences of high comorbidity should be the focus of research
attention. The majority of people with psychiatric disorders fail to obtain professional
treatment. Even among people with a lifetime history of three or more comorbid disorders,
the proportion who ever obtain specialty sector mental health treatment is less than 50%.
These results argue for the importance of more outreach and more research on barriers to
professional help-seeking

The primary use of these maps is likely to be as a new estimator of Galactic extinction. To
calibrate our maps, we assume a standard reddening law and use the colors of elliptical
galaxies to measure the reddening per unit flux density of 100 mu m emission. We find
consistent calibration using the B-R color distribution of a sample of the 106 brightest
cluster ellipticals, as well as a sample of 384 ellipticals with B-V and Mg line strength
measurements. For the latter sample, we use the correlation of intrinsic B-V versus Mg,
index to tighten the power of the test greatly. We demonstrate that the new maps are twice
as accurate as the older Burstein-Heiles reddening estimates in regions of low and
moderate reddening. The maps are expected to be significantly more accurate in regions
of high reddening. These dust maps will also be useful for estimating millimeter emission
that contaminates cosmic microwave background radiation experiments and for
estimating soft X-ray absorption. We describe how to access our maps readily for general
use.

algorithm that reconstructs a close approximation of 1-D and 2-D signals from their
multiscale edges. For images, the reconstruction errors are below our visual sensitivity. As
an application, we implement a compact image coding algorithm that selects important
edges and compresses the image data by factors over 30.

Abstract: We derive a new self-organizing learning algorithm that maximizes the
information transferred in a network of nonlinear units. The algorithm does not assume
any knowledge of the input distributions, and is defined here for the zero-noise limit.
Under these conditions, information maximization has extra properties not found in the
linear case (Linsker 1989). The nonlinearities in the transfer function are able to pick up
higher-order moments of the input distributions and perform something akin to true
redundancy reduction between units in the output representation. This enables the
network to separate statistically independent components in the inputs: a higher-order
generalization of principal components analysis. We apply the network to the source
separation (or cocktail party) problem, successfully separating unknown mixtures of up to
10 speakers. We also show that a variant on the network architecture is able to perform
blind deconvolution (cancellation of unknown echoes and reverberation in a speech
signal). Finally, we derive dependencies of information transfer on time delays. We
suggest that information maximization provides a unifying framework for problems in
''blind'' signal processing.

Abstract: PYTHIA and JETSETare the two main components of the ''Lund Monte Carlo''
program suite. They can be used to generate high-energy-physics ''events'', i.e. sets of
outgoing particles produced in the interactions between two incoming particles. Ideally
these events should have the same average behaviour and the same fluctuations as real
data. The underlying physics is not understood well enough to give an exact description,
the programs therefore contain a combination of analytical results and various models.
Several event classes are considered, within and beyond the standard model. We give a

radiation, multiple interactions, beam remnants. fragmentation and decays. A brief outline
is also given of some programming aspects. A detailed physics description and manual is

• Abstract: Generalized gradient approximations (GGA's) for the exchange-correlation
energy improve upon the local spin density (LSD) description of atoms, molecules, and
solids. We present a simple derivation of a simple GGA, in which all parameters (other
than those in LSD) are fundamental constants. Only general features of the detailed
construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.
Improvements over PW91 include an accurate description of the linear response of the
uniform electron gas, correct behavior under uniform scaling, and a smoother potential.

• Abstract: We present the derivation of a new molecular mechanical force field for
simulating the structures, conformational energies, and interaction energies of proteins,
nucleic acids, and many related organic molecules in condensed phases. This effective
two-body force field is the successor to the Weiner et al, force field and was developed
with some of the same philosophies, such as the use of a simple diagonal potential
function and electrostatic potential fit atom centered charges. The need for a 10-12
function for representing hydrogen bonds is no longer necessary due to the improved
performance of the new charge model and new van der Waals parameters. These new
charges are determined using a 6-31G basis set and restrained electrostatic potential
(RESP) fitting and have been shown to reproduce interaction energies, free energies of
solvation, and conformational energies of simple small molecules to a good degree of
accuracy. Furthermore, the new RESP charges exhibit less variability as a function of the
molecular conformation used in the charge determination. The new van der Waals
parameters have been derived from liquid simulations and include hydrogen parameters

which take into account the effects of any geminal electronegative atoms. The bonded
parameters developed by Weiner et al. were modified as necessary to reproduce
experimental vibrational frequencies and structures. Most of the simple dihedral
parameters have been retained from Weiner et. al., but a complex set of phi and psi
parameters which do a good job of reproducing the energies of the low-energy
conformations of glycyl and alanyl dipeptides has been developed for the peptide
backbone.

• Abstract: THE increase in the number of reports of abnormalities in male sex
development in wildlife and humans coincided with the introduction of 'oestrogenic'
chemicals such as DDT (1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane) into the
environment, Although these phenotypic alterations are thought to be mediated by the
oestrogen receptor, they are also consistent with inhibition of androgen receptor-mediated
events, Here we report that the major and persistent DDT metabolite, p,p'-DDE
(1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene), has little ability to bind the oestrogen
receptor, but inhibits androgen binding to the androgen receptor, androgen-induced
transcriptional activity, and androgen action in developing, pubertal and adult male rats,
The results suggest that abnormalities in male sex development induced by p,p'-DDE and
related environmental chemicals may be mediated at the level of the androgen receptor

ANTISOCIAL-BEHAVIOR - A DEVELOPMENTAL TAXONOMY
Source: PSYCHOLOGICAL REVIEW, 100 (4): 674-701 OCT 1993《心理学评论》美国
SCI 被引用 1340
Abstract: A dual taxonomy is presented to reconcile 2 incongruous facts about antisocial
behavior (a) It shows impressive continuity over age, but (b) its prevalence changes
dramatically over age, increasing almost 10-fold temporarily during adolescence. This
article suggests that delinquency conceals 2 distinct categories of individuals, each with a
unique natural history and etiology: A small group engages in antisocial behavior of 1 sort
or another at every life stage, whereas a larger group is antisocial only during adolescence.
According to the theory of life-course-persistent antisocial behavior, children's
neuropsychological problems interact cumulatively with their criminogenic environments
across development, culminating in a pathological personality. According to the theory of
adolescence-limited antisocial behavior, a contemporary maturity gap encourages teens to
mimic antisocial behavior in ways that are normative and adjustive.

This revision supersedes the four previous updates in which a nomenclature system,
based on divergent evolution of the superfamily, has been described. For the gene, we
recommend that the italicized root symbol 'CYP' for human ('Cyp' for mouse and
Drosophila), representing 'cytochrome P450', be followed by an Arabic number denoting
the family, a letter designating the subfamily (when two or more exist), and an Arabic
numeral representing the individual gene within the subfamily. A hyphen is no longer
recommended in mouse gene nomenclature. 'P' ('ps' in mouse and Drosophila) after the
gene number denotes a pseudogene; 'X' after the gene number means its use has been
discontinued. If a gene is the sole member of a family, the subfamily letter and gene
number would be helpful but need not be included. The human nomenclature system
should be used for all species other than mouse and Drosophila. The cDNAs, mRNAs and
enzymes in all species (including mouse) should include all capital letters, and without
italics or hyphens. This nomenclature system is similar to that proposed in our previous
updates.

calculation show that the mesoporous silica film is SBA-16 with Im3m space group
symmetry, and SBA-16 powder with unit cell parameters (a) of 193 Å and 186 Å for
calcined SBA-16 film.
The N2 adsportion-desorption experiment indicates that SBA -16 has BET
surface areas of 534.45m2/g, a mean pore sizes of 160Å and the total pore volume
of 0.376cm3/g.
Fe nanowire paralleling in arrays have been prepared by direct current
electrodeposition in highly ordered SBA-16 films. Homogenerous filling of all the
pores of the SBA-16 films is achieved. And the diameter of Fe nanowires can be
varied between 100-300Å, which corresponds to the diameters of the pores of the

• 最后一句给人的印象是作者通过加一种有机物来调节介孔分子筛的孔道大小,从而
调控铁纳米线的粗细。事实上,作者并没有做这件事,而是凭想象写下这段文字的。
实验结果表明,氧化铁的纳米线粗细和孔道大小没有直接的关系。
