text: A method of automatic conversion of a physical object into a three-dimensional
digital model. The method acquires a set of measured data points on the surface
of a physical model. From the measured data points, the method reconstructs a
digital model of the physical object using a Delaunay complex of the points, a
flow strcuture of the simplicies in the Delaunay complex and retracting the Delaunay
complex into a digital model of the physical object using the flow structure.
The method then outputs the digital model of the physical object.

text: 'Information in neuronal networks is thought to be represented by the rate
of discharge and the temporal relationship between the discharging neurons. The
discharge frequency of neurons is affected by their afferents and intrinsic properties,
and shows great individual variability. The temporal coordination of neurons is
greatly facilitated by network oscillations. In the hippocampus, population synchrony
fluctuates during theta and gamma oscillations (10-100 ms scale) and can increase
almost 10-fold during sharp wave bursts. Despite these large changes in excitability
in the sub-second scale, longer-term (minute-scale) firing rates of individual
neurons are relatively constant in an unchanging environment. As a result, mean
hippocampal output remains stable over time. To understand the mechanisms responsible
for this homeostasis, we address the following issues: (i) Can firing rates of
single cells be modified? (ii) Once modified, what mechanism(s) can maintain the
changes? We show that firing rates of hippocampal pyramidal cells can be altered
in a novel environment and by Hebbian pairing of physiological input patterns
with postsynaptic burst discharge. We also illustrate a competition between single
spikes and the occurrence of spike bursts. Since spike-inducing (suprathreshold)
inputs decrease the ability of strong (''teaching'') inputs to induce a burst
discharge, we propose that the single spike versus burst competition presents
a homeostatic regulatory mechanism to maintain synaptic strength and, consequently,
firing rate in pyramidal cells.'

text: In 1991, Barton and Turelli developed recursions to describe the evolution
of multilocus systems under arbitrary forms of selection. This article generalizes
their approach to allow for arbitrary modes of inheritance, including diploidy,
polyploidy, sex linkage, cytoplasmic inheritance, and genomic imprinting. The
framework is also extended to allow for other deterministic evolutionary forces,
including migration and mutation. Exact recursions that fully describe the state
of the population are presented; these are implemented in a computer algebra package
(available on the Web at http://helios.bto.ed.ac.uk/evolgen). Despite the generality
of our framework, it can describe evolutionary dynamics exactly by just two equations.
These recursions can be further simplified using a "quasi-linkage equilibrium"
(QLE) approximation. We illustrate the methods by finding the effect of natural
selection, sexual selection, mutation, and migration on the genetic composition
of a population.

text: A central problem in biology is determining how genes interact as parts of
functional networks. Creation and analysis of synthetic networks, composed of
well-characterized genetic elements, provide a framework for theoretical modeling.
Here, with the use of a combinatorial method, a library of networks with varying
connectivity was generated in Escherichia coli. These networks were composed of
genes encoding the transcriptional regulators Lacl, TetR, and lambda Cl, as well
as the corresponding promoters. They displayed phenotypic behaviors resembling
binary logical circuits, with two chemical “inputs” and a fluorescent protein
“output.” Within this simple system, diverse computational functions arose through
changes in network connectivity. Combinatorial synthesis provides an alternative
approach for studying biological networks, as well as an efficient method for
producing diverse phenotypes in vivo.

text: 'GABAergic interneurones are diverse in their morphological and functional
properties. Perisomatic inhibitory cells show fast spiking during sustained current
injection, whereas dendritic inhibitory cells fire action potentials with lower
frequency. We examined functional and molecular properties of K(+) channels in
interneurones with horizontal dendrites in stratum oriens-alveus (OA) of the hippocampal
CA1 region, which mainly comprise somatostatin-positive dendritic inhibitory cells.
Voltage-gated K(+) currents in nucleated patches isolated from OA interneurones
consisted of three major components: a fast delayed rectifier K(+) current component
that was highly sensitive to external 4-aminopyridine (4-AP) and tetraethylammonium
(TEA) (half-maximal inhibitory concentrations < 0.1 mM for both blockers),
a slow delayed rectifier K(+) current component that was sensitive to high concentrations
of TEA, but insensitive to 4-AP, and a rapidly inactivating A-type K(+) current
component that was blocked by high concentrations of 4-AP, but resistant to TEA.
The relative contributions of these components to the macroscopic K(+) current
were estimated as 57 +/- 5, 25 +/- 6, and 19 +/- 2 %, respectively. Dendrotoxin,
a selective blocker of Kv1 channels had only minimal effects on K(+) currents
in nucleated patches. Coapplication of the membrane-permeant cAMP analogue 8-(4-chlorophenylthio)-adenosine
3'':5''-cyclic monophosphate (cpt-cAMP) and the phosphodiesterase blocker isobutyl-methylxanthine
(IBMX) resulted in a selective inhibition of the fast delayed rectifier K(+) current
component. This inhibition was absent in the presence of the protein kinase A
(PKA) inhibitor H-89, implying the involvement of PKA-mediated phosphorylation.
Single-cell reverse transcription-polymerase chain reaction (RT-PCR) analysis
revealed a high abundance of Kv3.2 mRNA in OA interneurones, whereas the expression
level of Kv3.1 mRNA was markedly lower. Similarly, RT-PCR analysis showed a high
abundance of Kv4.3 mRNA, whereas Kv4.2 mRNA was undetectable. This suggests that
the fast delayed rectifier K(+) current and the A-type K(+) current component
are mediated predominantly by homomeric Kv3.2 and Kv4.3 channels. Selective modulation
of Kv3.2 channels in OA interneurones by cAMP is likely to be an important factor
regulating the activity of dendritic inhibitory cells in principal neurone-interneurone
microcircuits.'

text: Networks of GABAergic interneurons are of critical importance for the generation
of gamma frequency oscillations in the brain. To examine the underlying synaptic
mechanisms, we made paired recordings from "basket cells" (BCs) in different
subfields of hippocampal slices, using transgenic mice that express enhanced green
fluorescent protein (EGFP) under the control of the parvalbumin promoter. Unitary
inhibitory postsynaptic currents (IPSCs) showed large amplitude and fast time
course with mean amplitude-weighted decay time constants of 2.5, 1.2, and 1.8
ms in the dentate gyrus, and the cornu ammonis area 3 (CA3) and 1 (CA1), respectively
(33-34 degrees C). The decay of unitary IPSCs at BC-BC synapses was significantly
faster than that at BC-principal cell synapses, indicating target cell-specific
differences in IPSC kinetics. In addition, electrical coupling was found in a
subset of BC-BC pairs. To examine whether an interneuron network with fast inhibitory
synapses can act as a gamma frequency oscillator, we developed an interneuron
network model based on experimentally determined properties. In comparison to
previous interneuron network models, our model was able to generate oscillatory
activity with higher coherence over a broad range of frequencies (20-110 Hz).
In this model, high coherence and flexibility in frequency control emerge from
the combination of synaptic properties, network structure, and electrical coupling.

text: 'To examine possible interactions between fast depression and modulation of
inhibitory synaptic transmission in the hippocampus, we recorded from pairs of
synaptically connected basket cells (BCs) and granule cells (GCs) in the dentate
gyrus of rat brain slices at 34 degrees C. Multiple-pulse depression (MPD) was
examined in trains of 5 or 10 inhibitory postsynaptic currents (IPSCs) evoked
at frequencies of 10-100 Hz under several conditions that inhibit transmitter
release: block of voltage-dependent Ca2+ channels by Cd2+ (10 microM), activation
of gamma-amino-butyric acid type B receptors (GABA(B)Rs) by baclofen (10 microM)
and activation of muscarinic acetylcholine receptors (mAchRs) by carbachol (2
microM). All manipulations led to a substantial inhibition of synaptic transmission,
reducing the amplitude of the first IPSC in the train (IPSC1) by 72%, 61% and
29%, respectively. However, MPD was largely preserved under these conditions (0.34
in control versus 0.31, 0.50 and 0.47 in the respective conditions at 50 Hz).
Similarly, a theta burst stimulation (TBS) protocol reduced IPSC1 by 54%, but
left MPD unchanged (0.40 in control and 0.39 during TBS). Analysis of both fractions
of transmission failures and coefficients of variation (CV) of IPSC peak amplitudes
suggested that MPD had a presynaptic expression site, independent of release probability.
In conclusion, different types of presynaptic modulation of inhibitory synaptic
transmission converge on a reduction of synaptic strength, while short-term dynamics
are largely unchanged.'

text: The presynaptic Ca2+ signal is a key determinant of transmitter release at
chemical synapses. In cortical synaptic terminals, however, little is known about
the kinetic properties of the presynaptic Ca2+ channels. To investigate the timing
and magnitude of the presynaptic Ca2+ inflow, we performed whole-cell patch-clamp
recordings from mossy fiber boutons (MFBs) in rat hippocampus. MFBs showed large
high-voltage-activated Ca(2+) currents, with a maximal amplitude of approximately
100 pA at a membrane potential of 0 mV. Both activation and deactivation were
fast, with time constants in the submillisecond range at a temperature of approximately
23 degrees C. An MFB action potential (AP) applied as a voltage-clamp command
evoked a transient Ca2+ current with an average amplitude of approximately 170
pA and a half-duration of 580 microsec. A prepulse to +40 mV had only minimal
effects on the AP-evoked Ca2+ current, indicating that presynaptic APs open the
voltage-gated Ca2+ channels very effectively. On the basis of the experimental
data, we developed a kinetic model with four closed states and one open state,
linked by voltage-dependent rate constants. Simulations of the Ca2+ current could
reproduce the experimental data, including the large amplitude and rapid time
course of the current evoked by MFB APs. Furthermore, the simulations indicate
that the shape of the presynaptic AP and the gating kinetics of the Ca2+ channels
are tuned to produce a maximal Ca2+ influx during a minimal period of time. The
precise timing and high efficacy of Ca2+ channel activation at this cortical glutamatergic
synapse may be important for synchronous transmitter release and temporal information
processing.

text: Mossy fiber (MF) synapses are key stations for flow of information through
the hippocampal formation. A major component of the output of the MF system is
directed towards inhibitory interneurons. Recent studies have revealed that the
functional properties of MF-interneuron synapses differ substantially from those
of MF-CA3 pyramidal neuron synapses. Mossy-fiber-interneuron synapses in the stratum
lucidum represent a continuum of functional subtypes, in which the subunit composition
of postsynaptic AMPA receptors and NMDA receptors appears to be regulated in a
coordinated manner.

text: Hamilton's concept of local mate competition (LMC) is the standard model to
explain female-biased sex ratios in solitary Hymenoptera. In social Hymenoptera,
however, LMC has remained controversial, mainly because manipulation of sex allocation
by workers in response to relatedness asymmetries is an additional powerful mechanism
of female bias. Furthermore, the predominant mating systems in the social insects
are thought to make LMC unlikely. Nevertheless, several species exist in which
dispersal of males is limited and mating occurs in the nest. Some of these species,
such as the ant Cardiocondyla obscurior, have evolved dimorphic males, with one
morph being specialized for dispersal and the other for fighting with nest-mate
males over access to females. Such life history, combining sociality and alternative
reproductive tactics in males, provides a unique opportunity to test the power
of LMC as a selective force leading to female-biased sex ratios in social Hymenoptera.
We show that, in concordance with LMC predictions, an experimental increase in
queen number leads to a shift in sex allocation in favour of non-dispersing males,
but does not influence the proportion of disperser males. Furthermore, we can
assign this change in sex allocation at the colony level to the queens and rule
out worker manipulation.

text: 'Males of the ant Cardiocondyla show a dispersal dimorphism of a winged and
wingless morph. The loss of flight has lead to morphological reductions in the
wingless (ergatoid) males and also affected body size, eye size and pigmentation.
As ergatoid males mate exclusively inside the maternal nest, they underlie increased
male-male competition and therefore have also evolved additional changes in behaviour
and physiology: in contrast to winged males, ergatoid males are highly aggressive
towards each other and their spermatogenesis is prolonged compared to all other
hymenopteran males. In addition to these two male morphs, we found males with
an intermediate appearance. These "intermorphic" males provide a transitional
stage between normal males in most investigated morphological and physiological
parameters. As they are produced extremely rarely and only in colonies that switch
between pure ergatoid to mixed male production, we argue that they likely represent
a developmental mistake. Parallels between the determination of male morphs and
female castes (queen-worker dimorphism and worker polymorphism) might help to
understand how the large potential of phenotypic plasticity in both sexes of social
insects is realised during development.'

winged males and S. Buchhauser for help with the photographs. This study was funded

text: Males of the tropical ant Cardiocondyla obscurior are either wingless and
aggressive or winged and docile, and both compete for access to virgin queens
in the nest1, 2. Although the fighter males (ergatoids) attack and kill other
ergatoids, they tolerate and even attempt to mate with their winged rivals. Here
we show that the winged males avoid the aggression of wingless males by mimicking
the chemical bouquet of virgin queens, but that their mating success is not reduced
as a result. This example of female mimicry by vigorous males is surprising, as
in other species it is typically used as a protective strategy by weaker males,
and may explain the coexistence and equal mating success of two male morphs.

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
lifetime or persistence within the filtration. We give fast algorithms for computing
persistence and experimental evidence for their speed and utility.

Delaunay triangulations. The first step refines the triangulation by inserting
sinks and eliminates tetrahedra with large circumradius over shortest edge length

experimental findings provide evidence for the practical effectiveness of sliver

and switches to simpler algorithms for low numbers of boxes. We use our implementations
as engines to solve problems about geometric primitives. We look at two such problems
in the category of quality analysis of surface triangulations.

text: The writhing number measures the global geometry of a closed space curve or
knot. We show that this measure is related to the average winding number of its
Gauss map. Using this relationship, we give an algorithm for computing the writhing
number for a polygonal knot with n edges in time roughly proportional to n(1.6).
We also implement a different, simple algorithm and provide experimental evidence
for its practical efficiency.

text: Pilot studies in England by Stopka and Macdonald revealed that allogrooming
in the Old World wood mouse, Apodemus sylvaticus, is a commodity that males can
trade for reproductive benefits with females. This study, which used a combination
of field study and observations in experimental enclosures, revealed that specific
experimental conditions such as group-size and sex-ratio manipulations have a
significant effect on the pattern of allogrooming exchanged between individuals.
Furthermore, females from the Czech population were more likely to associate with
each other as revealed by the clustering of activity centers of females (i.e.,
as opposed to almost exclusive ranges in English populations), and also by the
higher intensity of allogrooming exchanged between females (i.e., virtually lacking
in the previous experiment with English mice). Therefore, geographic variation
and specific social conditions seem to be important driving factors for allogrooming
behavior. Together with changes in overall grooming patterns, allogrooming between
males and females remained invariably asymmetrical over all four experimental
groups (i.e., two conditions for each sex) in that males provided more allogrooming
to females than they received from them.

text: Members of the Wnt family have been implicated in a variety of developmental
processes including axis formation, Patterning of the central nervous system and
tissue morphogenesis. Recent studies have shown that a Wnt signalling pathway
similar to that involved in the establishment of planar cell polarity in Drosophila
regulates convergent extension movements during zebrafish and Xenopus gastrulation.
This finding provides a good starting point to dissect the complex cell biology
and genetic regulation of vertebrate gastrulation movements.
