text: A sliver is a tetrahedron whose four vertices lie close to a plane and whose
perpendicular projection to that plane is a convex quadrilateral with no short
edge. Slivers are both undesirable and ubiquitous in 3-dimensional Delaunay triangulations.
Even when the point-set is well-spaced, slivers may result. This paper shows that
such a point set permits a small perturbation whose Delaunay triangulation contains
no slivers. It also gives deterministic algorithms that compute the perturbation
of n points in time O(n log n) with one processor and in time O(log n) with O(n)
processors.

text: The Delaunay triangulation of a finite point set is a central theme in computational
geometry. It finds its major application in the generation of meshes used in the
simulation of physical processes. This paper connects the predominantly combinatorial
work in classical computational geometry with the numerical interest in mesh generation.
It focuses on the two- and three-dimensional case and covers results obtained
during the twentieth century.

text: 'We present the theoretical background to a new method for measuring genetic
variation for total fitness in Drosophila. The method allows heterozygous effects
on total fitness of whole wild-type chromosomes to be measured under normal demography
with overlapping generations. The wild-type chromosomes are competed against two
balancer chromosomes (B1, B2, say), providing a standard genotype B1/B2 against
which variation in the fitness effects of the wild-type chromosomes can be assessed.
Fitness can be assessed in two ways: (i) at equilibrium of all three chromosomes
under heterozygote advantage, and (ii) during displacement of one balancer by
the other. Equilibrium with all three chromosomes present will be achieved only
if the wild-type homozygote is not too fit, and if the fitnesses of the three
heterozygotes are not too unequal. These conditions were not satisfied for any
of a sample of 12 lethal-bearing chromosomes isolated from a random-bred laboratory
population of Drosophila. At equilibrium, genotypic frequencies show low sensitivity
to changes in genotypic fitness. Furthermore, where all four genotypes are viable
and fertile, supplementary information from cages with only two chromosomes present
and from direct measurements of pre-adult viability are required to estimate fitnesses
from frequencies. The invasion method has the advantages of a greater sensitivity
and of not requiring further data to estimate fitnesses if the wild-type homozygote
is fertile. However, it requires that multiple samples be taken as the invasion
progresses. In a discrete generation model, generation time influences fitness
estimates from this method and is difficult to estimate accurately from the data.
A full age-structured model can also be applied to the data from both types of
experiment. For the invasion method, this gives fitness estimates close to those
from the discrete generation model.'

text: 'The state of a diploid population segregating for two alleles at each of
n loci is described by 22(n) genotype frequencies, or equivalently, by allele
frequencies and by multilocus moments or cumulants of various orders. These measures
of linkage disequilibrium cannot usually be determined, both because one cannot
tell whether a gene came from the maternal or paternal gamete, and because such
a large number of parameters cannot be estimated even from large samples. Simplifying
assumptions must therefore be made. This paper sets out methods for estimating
multilocus genotype frequencies which are appropriate for unlinked neutral loci,
and for populations that are ultimately derived by mixing of two source populations.
In such a hybrid population, all multilocus associations depend primarily on the
number of loci involved that derive from the maternal genome, and the number derived
from the paternal genome Allele frequencies may differ across loci, and the contribution
of each locus to multilocus associations may be scaled by the difference in allele
frequency between source populations for that locus (δp ≤ 1). For example, the
cumulant describing the association between genes i, j, k from the maternal genome,
and genes i, l from the paternal genome is K(tJ,k,iλ*), = δp(i)/2 δp(J) δp(k)
δp(l) κ3,2. The state of the population is described by n allele frequencies;
n divergences, δp; and by a symmetric matrix of cumulants, κ(J,K) (J = 0 ,...,
n, K = 0 ,..., n). Expressions for these cumulants under short- and long-range
migration are given. Two methods for estimating the cumulants are described: a
simple method based on multivariate moments, and a maximum likelihood procedure,
which uses the Metropolis algorithm. Both methods perform well when tested against
simulations with two or four loci.'

text: Glutamate is the main excitatory transmitter in the mammalian CNS, mediating
fast synaptic transmission primarily by activation of AMPA-type glutamate receptor
channels. Both synaptic structure and a cell-specific molecular switch in the
AMPA receptor subunit expression are involved in the regulation of the synaptic
signaling time course.

text: In this paper we introduce the abacus model of a simplex and use it to subdivide
a d-simplex into k(d) d-simplices all of the same volume and shape characteristics.
The construction is an extension of the subdivision method of Freudenthal [3]
and has been used by Goodman and Peters [4] to design smooth manifolds.

text: We formalize a notion of topological simplification within the framework of
a filtration, which is the history of a growing complex. We classify a topological
change that happens during growth as either a feature or noise depending on its
life-time or persistence within the filtration. We give fast algorithms for computing
persistence and experimental evidence for their speed and utility.

text: We study the maintenance of a simplicial grid or complex under changing density
requirements. The proposed method works in any fixed dimension and generates grids
by projecting cross-sections of a monotone simplicial complex that lives in one
dimension higher than the grid. The density of the grid is adapted by locally
moving the cross-section up or down along the extra dimension.

text: A sliver is a tetrahedron whose four vertices lie close to a plane and whose
orthogonal projection to that plane is a convex quadrilateral with no short edge.
Slivers are notoriously common in 3-dimensional Delaunay triangulations even for
well-spaced point sets. We show that, if the Delaunay triangulation has the ratio
property introduced in Miller et al. [1995], then there is an assignment of weights
so the weighted Delaunay triangulation contains no slivers. We also give an algorithm
to compute such a weight assignment.

text: We have developed a protocol to perform a genetic screen for zygotic mutations
affecting embryogenesis on the protochordate Ciona intestinalis. The choice of
this taxon, whose phylogenetic position places it at the basis of the chordates
as one the most primitive vertebrate relatives, could allow to address several
evolutionary questions. The protochordates share many morphological features with
the vertebrates, in primis the presence of a notochord. Ciona intestinalis shows
several ideal features for a mutational analysis, such as external development
and larvae made of a limited number of cells and cell types. Detailed cell lineage
studies are available. The haploid genome size is comparable to the size of the
Drosophila haploid genome. We have optimised conditions for chemical mutagenesis
studying the efficiency at which different concentration of N-ethyl-N-nitrosourea
(ENU) can induce mutations. Because the adult Ciona are hermaphrodites, we are
performing a one-generation screen. The induced mutations are identified by visual
inspection of developmental stages. We report the preliminary results from our
screen including examples of the different classes of mutant phenotypes found
so far.

text: Vertebrate gastrulation involves the specification and coordinated movement
of large populations of cells that give rise to the ectodermal, mesodermal and
endodermal germ layers. Although many of the genes involved in the specification
of cell identity during this process have been identified, little is known of
the genes that coordinate cell movement. Here we show that the zebrafish silberblick
(slb) locus(1) encodes Wnt11 and that Slb/Wnt11 activity is required for cells
to undergo correct convergent extension movements during gastrulation. In the
absence of Slb/Wnt11 function, abnormal extension of axial tissue results in cyclopia
and other midline defects in the head(2). The requirement for Slb/Wnt11 is cell
non-autonomous, and our results indicate that the correct extension of axial tissue
is at least partly dependent on medio-lateral cell intercalation in paraxial tissue.
We also show that the slb phenotype is rescued by a truncated form of Dishevelled
that does not signal through the canonical Wnt pathway(3), suggesting that, as
in flies(4), Wnt signalling might mediate morphogenetic events through a divergent
signal transduction cascade. Our results provide genetic and experimental evidence
that Wnt activity in lateral tissues has a crucial role in driving the convergent
extension movements underlying vertebrate gastrulation.

text: 'A coalescence-based maximum-likelihood method is presented that aims to (i)
detect diversity-reducing events in the recent history of a population and (ii)
distinguish between demographic (e.g., bottlenecks) and selective causes (selective
sweep) of a recent reduction of genetic variability. The former goal is achieved
by taking account of the distortion in the shape of gene genealogies generated
by diversity-reducing events: gene trees tend to be more star-like than under
the standard coalescent. The latter issue is addressed by comparing patterns between
loci: demographic events apply to the whole genome whereas selective events affect
distinct regions of the genome to a varying extent. The maximum-likelihood approach
allows one to estimate the time and strength of diversity-reducing events and
to choose among competing hypotheses. An application to sequence data from an
African population of Drosophila melanogaster shows that the bottleneck hypothesis
is unlikely and that one or several selective sweeps probably occurred in the
recent history of this population.'

text: "Within hybrid zones that are maintained by a balance between selection and
dispersal, linkage disequilibrium is generated by the mixing of divergent populations.
This linkage disequilibrium causes selection on each locus to act on all other
loci, thereby steepening dines, and generating a barrier to gene flow. Diffusion
models predict simple relations between the strength of linkage disequilibrium
and the dispersal rate, σ, and between the barrier to gene flow, B, and the reduction
in mean fitness, W̄. The aim of this paper is to test the accuracy of these predictions
by comparison with an exact deterministic model of unlinked loci (r = 0.5). Disruptive
selection acts on the proportion of alleles from the parental populations (p,
q): W = exp[-S(4pq)(β)], such that the least fit genotype has fitness e(-S). Where
β << 1, fitness is reduced for a wide range of intermediate genotypes; where
β >> 1, fitness is only reduced for those genotypes close to p = 0.5. Even
with strong epistasis, linkage disequilibria are close to σ2p'(i)p'(j)/r(ij),
where p'(i), p'(j) are the gradients in allele frequency at loci i, j. The barrier
to gene flow, which is reflected in the steepening of neutral dines, is given
by B = ∫(-∞)(∞) (W̄(1/r̄)-1) dx, where r̄, the harmonic mean recombination rate
between the neural and selected loci, is here 0.5. This is a close approximation
for weak selection, but underestimates B for strong selection. The barrier is
stronger for small β, because hybrid fitness is then reduced over a wider range
of p. The widths of the selected dines are harder to predict: though simple approximations
are accurate for β = 1, they become inaccurate for extreme β because, then, fitness
changes sharply with p. Estimates of gene number, made from neutral dines on the
assumption that selection acts against heterozygotes, are accurate for weak selection
when β = 1; however, for strong selection, gene number is overestimated. For β
> 1, gene number is systematically overestimated and, conversely, when β <
1, it is underestimated.\r\n"

text: 'Analysis of multilocus evolution is usually intractable for more than n ~
10 genes, because the frequencies of very large numbers of genotypes must be followed.
An exact analysis of up to n ~ 100 loci is feasible for a symmetrical model, in
which a set of unlinked loci segregate for two alleles (labeled ''0'' and ''1'')
with interchangeable effects on fitness. All haploid genotypes with the same number
of 1 alleles can then remain equally frequent. However, such a symmetrical solution
may be unstable: for example, under stabilizing selection, populations tend to
fix any one genotype which approaches the optimum. Here, we show how the 2'' x
2'' stability matrix can be decomposed into a set of matrices, each no larger
than n x n. This allows the stability of symmetrical solutions to be determined.
We apply the method to stabilizing and disruptive selection in a single deme and
to selection against heterozygotes in a linear cline. (C) 2000 Academic Press.'

text: We review the various factors that limit adaptation by natural selection.
Recent discussion of constraints on selection and, conversely, of the factors
that enhance 'evolvability', have concentrated on the kinds of variation that
can be produced. Here, we emphasise that adaptation depends on how the various
evolutionary processes shape variation in populations. We survey the limits that
population genetics places on adaptive evolution, and discuss the relationship
between disparate literatures. BioEssays 22:1075-1084, 2000. (C) 2000 John Wiley

text: Selection on one or more genes inevitably perturbs other genes, even when
those genes have no direct effect on fitness. This article reviews the theory
of such genetic hitchhiking, concentrating on effects on neutral loci. Maynard
Smith and Haigh introduced the classical case where the perturbation is due to
a single favourable mutation. This is contrasted with the apparently distinct
effects of inherited variation in fitness due to loosely linked loci. A model
of fluctuating selection is analysed which bridges these alternative treatments.
When alleles sweep between extreme frequencies at a rate λ, the rate of drift
is increased by a factor (1 + E[1/pq]λ/(2(2λ + r))), where the recombination rate
r is much smaller than the strength of selection. In spatially structured populations,
the effects of any one substitution are weaker, and only cause a local increase
in the frequency of a neutral allele. This increase depends primarily on the rate
of recombination relative to selection (r/s), and more weakly, on the neighbourhood
size, Nb = 4πρσ2. Spatial subdivision may allow local selective sweeps to occur
more frequently than is indicated by the overall rate of molecular evolution.
However, it seems unlikely that such sweeps can be sufficiently frequent to increase
significantly the drift of neutral alleles.
