text: We present ABC, a software tool for automatically computing symbolic upper
bounds on the number of iterations of nested program loops. The system combines
static analysis of programs with symbolic summation techniques to derive loop
invariant relations between program variables. Iteration bounds are obtained from
the inferred invariants, by replacing variables with bounds on their greatest
values. We have successfully applied ABC to a large number of examples. The derived
symbolic bounds express non-trivial polynomial relations over loop variables.
We also report on results to automatically infer symbolic expressions over harmonic
numbers as upper bounds on loop iteration counts.

text: We address the problem of localizing homology classes, namely, finding the
cycle representing a given class with the most concise geometric measure. We focus
on the volume measure, that is, the 1-norm of a cycle. Two main results are presented.
First, we prove the problem is NP-hard to approximate within any constant factor.
Second, we prove that for homology of dimension two or higher, the problem is
NP-hard to approximate even when the Betti number is O(1). A side effect is the
inapproximability of the problem of computing the nonbounding cycle with the smallest
volume, and computing cycles representing a homology basis with the minimal total
volume. We also discuss other geometric measures (diameter and radius) and show
their disadvantages in homology localization. Our work is restricted to homology
over the ℤ2 field.

text: "Background: The availability of many gene alignments with overlapping taxon
sets raises the question of which strategy is the best to infer species phylogenies
from multiple gene information. Methods and programs abound that use the gene
alignment in different ways to reconstruct the species tree. In particular, different
methods combine the original data at different points along the way from the underlying
sequences to the final tree. Accordingly, they are classified into superalignment,
supertree and medium-level approaches. Here, we present a simulation study to
compare different methods from each of these three approaches.\r\n\r\nResults:
We observe that superalignment methods usually outperform the other approaches
over a wide range of parameters including sparse data and gene-specific evolutionary
parameters. In the presence of high incongruency among gene trees, however, other
combination methods show better performance than the superalignment approach.
Surprisingly, some supertree and medium-level methods exhibit, on average, worse
results than a single gene phylogeny with complete taxon information.\r\n\r\nConclusions:
For some methods, using the reconstructed gene tree as an estimation of the species
tree is superior to the combination of incomplete information. Superalignment
usually performs best since it is less susceptible to stochastic error. Supertree
methods can outperform superalignment in the presence of gene-tree conflict."

text: 'Classical models of gene flow fail in three ways: they cannot explain large-scale
patterns; they predict much more genetic diversity than is observed; and they
assume that loosely linked genetic loci evolve independently. We propose a new
model that deals with these problems. Extinction events kill some fraction of
individuals in a region. These are replaced by offspring from a small number of
parents, drawn from the preexisting population. This model of evolution forwards
in time corresponds to a backwards model, in which ancestral lineages jump to
a new location if they are hit by an event, and may coalesce with other lineages
that are hit by the same event. We derive an expression for the identity in allelic
state, and show that, over scales much larger than the largest event, this converges
to the classical value derived by Wright and Malécot. However, rare events that
cover large areas cause low genetic diversity, large-scale patterns, and correlations
in ancestry between unlinked loci.'

text: 'Streaming string transducers [1] define (partial) functions from input strings
to output strings. A streaming string transducer makes a single pass through the
input string and uses a finite set of variables that range over strings from the
output alphabet. At every step, the transducer processes an input symbol, and
updates all the variables in parallel using assignments whose right-hand-sides
are concatenations of output symbols and variables with the restriction that a
variable can be used at most once in a right-hand-side expression. It has been
shown that streaming string transducers operating on strings over infinite data
domains are of interest in algorithmic verification of list-processing programs,
as they lead to PSPACE decision procedures for checking pre/post conditions and
for checking semantic equivalence, for a well-defined class of heap-manipulating
programs. In order to understand the theoretical expressiveness of streaming transducers,
we focus on streaming transducers processing strings over finite alphabets, given
the existence of a robust and well-studied class of "regular" transductions
for this case. Such regular transductions can be defined either by two-way deterministic
finite-state transducers, or using a logical MSO-based characterization. Our main
result is that the expressiveness of streaming string transducers coincides exactly
with this class of regular transductions. '

text: Any programming error that can be revealed before compiling a program saves
precious time for the programmer. While integrated development environments already
do a good job by detecting, e.g., data-flow abnormalities, current static analysis
tools suffer from false positives ("noise") or require strong user interaction.
We propose to avoid this deficiency by defining a new class of errors. A program
fragment is doomed if its execution will inevitably fail, regardless of which
state it is started in. We use a formal verification method to identify such errors
fully automatically and, most significantly, without producing noise. We report
on experiments with a prototype tool.

text: "We present an algorithmic method for the synthesis of concurrent programs
that are optimal with respect to quantitative performance measures. The input
consists of a sequential sketch, that is, a program that does not contain synchronization
constructs, and of a parametric performance model that assigns costs to actions
such as locking, context switching, and idling. The quantitative synthesis problem
is to automatically introduce synchronization constructs into the sequential sketch
so that both correctness is guaranteed and worst-case (or average-case) performance
is optimized. Correctness is formalized as race freedom or linearizability.\r\n\r\nWe
show that for worst-case performance, the problem can be modeled\r\nas a 2-player
graph game with quantitative (limit-average) objectives, and\r\nfor average-case
performance, as a 2 1/2 -player graph game (with probabilistic transitions). In
both cases, the optimal correct program is derived from an optimal strategy in
the corresponding quantitative game. We prove that the respective game problems
are computationally expensive (NP-complete), and present several techniques that
overcome the theoretical difficulty in cases of concurrent programs of practical
interest.\r\n\r\nWe have implemented a prototype tool and used it for the automatic
syn- thesis of programs that access a concurrent list. For certain parameter val-
ues, our method automatically synthesizes various classical synchronization schemes
for implementing a concurrent list, such as fine-grained locking or a lazy algorithm.
For other parameter values, a new, hybrid synchronization style is synthesized,
which uses both the lazy approach and coarse-grained locks (instead of standard
fine-grained locks). The trade-off occurs because while fine-grained locking tends
to decrease the cost that is due to waiting for locks, it increases cache size
requirements."

text: The class of ω regular languages provide a robust specification language in
verification. Every ω-regular condition can be decomposed into a safety part and
a liveness part. The liveness part ensures that something good happens “eventually.”
Two main strengths of the classical, infinite-limit formulation of liveness are
robustness (independence from the granularity of transitions) and simplicity (abstraction
of complicated time bounds). However, the classical liveness formulation suffers
from the drawback that the time until something good happens may be unbounded.
A stronger formulation of liveness, so-called finitary liveness, overcomes this
drawback, while still retaining robustness and simplicity. Finitary liveness requires
that there exists an unknown, fixed bound b such that something good happens within
b transitions. In this work we consider the finitary parity and Streett (fairness)
conditions. We present the topological, automata-theoretic and logical characterization
of finitary languages defined by finitary parity and Streett conditions. We (a)
show that the finitary parity and Streett languages are Σ2-complete; (b) present
a complete characterization of the expressive power of various classes of automata
with finitary and infinitary conditions (in particular we show that non-deterministic
finitary parity and Streett automata cannot be determinized to deterministic finitary
parity or Streett automata); and (c) show that the languages defined by non-deterministic
finitary parity automata exactly characterize the star-free fragment of ωB-regular
languages.

text: Concurrent data structures with fine-grained synchronization are notoriously
difficult to implement correctly. The difficulty of reasoning about these implementations
does not stem from the number of variables or the program size, but rather from
the large number of possible interleavings. These implementations are therefore
prime candidates for model checking. We introduce an algorithm for verifying linearizability
of singly-linked heap-based concurrent data structures. We consider a model consisting
of an unbounded heap where each node consists an element from an unbounded data
domain, with a restricted set of operations for testing and updating pointers
and data elements. Our main result is that linearizability is decidable for programs
that invoke a fixed number of methods, possibly in parallel. This decidable fragment
covers many of the common implementation techniques — fine-grained locking, lazy
synchronization, and lock-free synchronization. We also show how the technique
can be used to verify optimistic implementations with the help of programmer annotations.
We developed a verification tool CoLT and evaluated it on a representative sample
of Java implementations of the concurrent set data structure. The tool verified
linearizability of a number of implementations, found a known error in a lock-free
imple- mentation and proved that the corrected version is linearizable.

text: "Purpose\r\nCalcifying tendinitis is a common condition of the shoulder. In
many cases, arthroscopic reduction in the deposit is indicated. The localization
of the deposit is sometimes challenging and time-consuming. Pre-operative ultrasound
(US)-guided needle placement in the deposit and pre-operative US marking of the
deposit at the skin with a ballpoint are described and recommended methods to
alleviate the procedure without using ionizing radiation by fluoroscopy.\r\nMethods\r\nIntra-operative
sonography of the shoulder is introduced as a new method to localize the calcific
deposit with high accuracy. After standard arthroscopic buresectomy, the surgeon
performs an ultrasound examination under sterile conditions to localize the deposits.
A ventral longitudinal US section is recommended, and the upper arm is rotated
until the deposit is visible. Subsequently, perpendicular to the skin at the position
of the transducer, a needle is introduced under arthroscopic and ultrasound visualization
to puncture the deposit.\r\nResults\r\nThe presence of snow-white crystals at
the tip of the needle proves the exact localization. Consecutively, the curettage
can be accomplished. Another intra-operative sonography evaluates possible calcific
remnants and the tendon structure.\r\nConclusion\r\nThis new technique may alleviate
arthroscopic calcific deposit curettage by visualizing the deposit without using
ionizing radiation. Additionally, soft tissue damage due to decreased number of
punctures to detect the deposit may be achieved. Both factors may contribute to
reduced operation time."

text: We investigated temporal changes in hybridization and introgression between
native red deer (Cervus elaphus) and invasive Japanese sika (Cervus nippon) on
the Kintyre Peninsula, Scotland, over 15 years, through analysis of 1513 samples
of deer at 20 microsatellite loci and a mtDNA marker. We found no evidence that
either the proportion of recent hybrids, or the levels of introgression had changed
over the study period. Nevertheless, in one population where the two species have
been in contact since ∼1970, 44% of individuals sampled during the study were
hybrids. This suggests that hybridization between these species can proceed fairly
rapidly. By analysing the number of alleles that have introgressed from polymorphic
red deer into the genetically homogenous sika population, we reconstructed the
haplotypes of red deer alleles introduced by backcrossing. Five separate hybridization
events could account for all the recently hybridized sika-like individuals found
across a large section of the Peninsula. Although we demonstrate that low rates
of F1 hybridization can lead to substantial introgression, the progress of hybridization
and introgression appears to be unpredictable over the short timescales.

text: Long-term depression (LTD) is a form of synaptic plasticity that may contribute
to information storage in the central nervous system. Here we report that LTD
can be elicited in layer 5 pyramidal neurons of the rat prefrontal cortex by pairing
low frequency stimulation with a modest postsynaptic depolarization. The induction
of LTD required the activation of both metabotropic glutamate receptors of the
mGlu1 subtype and voltage-sensitive Ca(2+) channels (VSCCs) of the T/R, P/Q and
N types, leading to the stimulation of intracellular inositol trisphosphate (IP3)
receptors by IP3 and Ca(2+). The subsequent release of Ca(2+) from intracellular
stores activated the protein phosphatase cascade involving calcineurin and protein
phosphatase 1. The activation of purinergic P2Y(1) receptors blocked LTD. This
effect was prevented by P2Y(1) receptor antagonists and was absent in mice lacking
P2Y(1) but not P2Y(2) receptors. We also found that activation of P2Y(1) receptors
inhibits Ca(2+) transients via VSCCs in the apical dendrites and spines of pyramidal
neurons. In addition, we show that the release of ATP under hypoxia is able to
inhibit LTD by acting on postsynaptic P2Y(1) receptors. In conclusion, these data
suggest that the reduction of Ca(2+) influx via VSCCs caused by the activation
of P2Y(1) receptors by ATP is the possible mechanism for the inhibition of LTD
in prefrontal cortex.

text: If distinct biological species are to coexist in sympatry, they must be reproductively
isolated and must exploit different limiting resources. A two-niche Levene model
is analysed, in which habitat preference and survival depend on underlying additive
traits. The population genetics of preference and viability are equivalent. However,
there is a linear trade-off between the chances of settling in either niche, whereas
viabilities may be constrained arbitrarily. With a convex trade-off, a sexual
population evolves a single generalist genotype, whereas with a concave trade-off,
disruptive selection favours maximal variance. A pure habitat preference evolves
to global linkage equilibrium if mating occurs in a single pool, but remarkably,
evolves to pairwise linkage equilibrium within niches if mating is within those
niches--independent of the genetics. With a concave trade-off, the population
shifts sharply between a unimodal distribution with high gene flow and a bimodal
distribution with strong isolation, as the underlying genetic variance increases.
However, these alternative states are only simultaneously stable for a narrow
parameter range. A sharp threshold is only seen if survival in the 'wrong' niche
is low; otherwise, strong isolation is impossible. Gene flow from divergent demes
makes speciation much easier in parapatry than in sympatry.

text: 1. Hybridisation with an invasive species has the potential to alter the phenotype
and hence the ecology of a native counterpart. 2. Here data from populations of
native red deer Cervus elaphus and invasive sika deer Cervus nippon in Scotland
is used to assess the extent to which hybridisation between them is causing phenotypic
change. This is done by regression of phenotypic traits against genetic hybrid
scores. 3. Hybridisation is causing increases in the body weight of sika-like
deer and decreases in the body weight of red-like females. Hybridisation is causing
increases in jaw length and increases in incisor arcade breadth in sika-like females.
Hybridisation is also causing decreases in incisor arcade breadth in red-like
females. 4. There is currently no evidence that hybridisation is causing changes
in the kidney fat weight or pregnancy rates of either population. 5. Increased
phenotypic similarity between the two species is likely to lead to further hybridisation.
The ecological consequences of this are difficult to predict.

questions in biology. The most compelling general explanation is that recombination
facilitates selection by breaking down the negative associations generated by
random drift (i.e. Hill-Robertson interference, HRI). I classify the effects of
HRI owing to: deleterious mutation, balancing selection and selective sweeps on:
neutral diversity, rates of adaptation and the mutation load. These effects are
mediated primarily by the density of deleterious mutations and of selective sweeps.
Sequence polymorphism and divergence suggest that these rates may be high enough
to cause significant interference even in genomic regions of high recombination.
However, neither seems able to generate enough variance in fitness to select strongly
for high rates of recombination. It is plausible that spatial and temporal fluctuations
in selection generate much more fitness variance, and hence selection for recombination,
than can be explained by uniformly deleterious mutations or species-wide selective
sweeps.'

text: 'Under the classical view, selection depends more or less directly on mutation:
standing genetic variance is maintained by a balance between selection and mutation,
and adaptation is fuelled by new favourable mutations. Recombination is favoured
if it breaks negative associations among selected alleles, which interfere with
adaptation. Such associations may be generated by negative epistasis, or by random
drift (leading to the Hill-Robertson effect). Both deterministic and stochastic
explanations depend primarily on the genomic mutation rate, U. This may be large
enough to explain high recombination rates in some organisms, but seems unlikely
to be so in general. Random drift is a more general source of negative linkage
disequilibria, and can cause selection for recombination even in large populations,
through the chance loss of new favourable mutations. The rate of species-wide
substitutions is much too low to drive this mechanism, but local fluctuations
in selection, combined with gene flow, may suffice. These arguments are illustrated
by comparing the interaction between good and bad mutations at unlinked loci under
the infinitesimal model.'

text: Crosses between closely related species give two contrasting results. One
result is that species hybrids may be inferior to their parents, for example,
being less fertile [1]. The other is that F1 hybrids may display superior performance
(heterosis), for example with increased vigour [2]. Although various hypotheses
have been proposed to account for these two aspects of hybridisation, their biological
basis is still poorly understood [3]. To gain further insights into this issue,
we analysed the role that variation in gene expression may play. We took a conserved
trait, flower asymmetry in Antirrhinum, and determined the extent to which the
underlying regulatory genes varied in expression among closely related species.
We show that expression of both genes analysed, CYC and RAD, varies significantly
between species because of cis-acting differences. By making a quantitative genotype-phenotype
map, using a range of mutant alleles, we demonstrate that the species lie on a
plateau in gene expression-morphology space, so that the variation has no detectable
phenotypic effect. However, phenotypic differences can be revealed by shifting
genotypes off the plateau through genetic crosses. Our results can be readily
explained if genomes are free to evolve within an effectively neutral zone in
gene expression space. The consequences of this drift will be negligible for individual
loci, but when multiple loci across the genome are considered, we show that the
variation may have significant effects on phenotype and fitness, causing a significant
drift load. By considering these consequences for various gene-expression-fitness
landscapes, we conclude that F1 hybrids might be expected to show increased performance
with regard to conserved traits, such as basic physiology, but reduced performance
with regard to others. Thus, our study provides a new way of explaining how various
aspects of hybrid performance may arise through natural variation in gene activity.

text: In cortex surface segmentation, the extracted surface is required to have
a particular topology, namely, a two-sphere. We present a new method for removing
topology noise of a curve or surface within the level set framework, and thus
produce a cortical surface with correct topology. We define a new energy term
which quantifies topology noise. We then show how to minimize this term by computing
its functional derivative with respect to the level set function. This method
differs from existing methods in that it is inherently continuous and not digital;
and in the way that our energy directly relates to the topology of the underlying
curve or surface, versus existing knot-based measures which are related in a more
indirect fashion. The proposed flow is validated empirically.
