text: Mechanical unfolding of single bacteriorhodopsins from a membrane bilayer
is studied using molecular dynamics simulations. The initial conformation of the
lipid membrane is determined through all-atom simulations and then its coarse-grained
representation is used in the studies of stretching. A Go-like model with a realistic
contact map and with Lennard–Jones contact interactions is applied to model the
protein–membrane system. The model qualitatively reproduces the experimentally
observed differences between force-extension patterns obtained on bacteriorhodopsin
at different temperatures and predicts a lack of symmetry in the choice of the
terminus to pull by. It also illustrates the decisive role of the interactions
of the protein with the membrane in determining the force pattern and thus the
stability of transmembrane proteins.

text: Measuring the visco-elastic properties of biological macromolecules constitutes
an important step towards the understanding of dynamic biological processes, such
as cell adhesion, muscle function, or plant cell wall stability. Force spectroscopy
techniques based on the atomic force microscope (AFM) are increasingly used to
study the complex visco-elastic response of (bio-)molecules on a single-molecule
level. These experiments either require that the AFM cantilever is actively oscillated
or that the molecule is clamped at constant force to monitor thermal cantilever
motion. Here we demonstrate that the visco-elasticity of single bio-molecules
can readily be extracted from the Brownian cantilever motion during conventional
force-extension measurements. It is shown that the characteristics of the cantilever
determine the signal-to-noise (S/N) ratio and time resolution. Using a small cantilever,
the visco-elastic properties of single dextran molecules were resolved with a
time resolution of 8.3 ms. The presented approach can be directly applied to probe
the dynamic response of complex bio-molecular systems or proteins in force-extension
experiments.

text: We applied a single-cell assay to characterize how transcription dynamics
affects protein expression levels of a tetracycline-inducible gene expression
system. Transcriptional activity of the tetracycline promoter in response to a
steady level of inducer is steady in ΔacrAB efflux mutant but pulsating in wildtype
Escherichia coli cells. We found that the expression level of the green fluorescent
protein is several folds higher in ΔacrAB efflux mutant than in wildtype cells.

text: A primitive example of adaptation in gene expression is the balance between
the rate of synthesis and degradation of cellular RNA, which allows rapid responses
to environmental signals. Here, we investigate how multidrug efflux pump systems
mediate the dynamics of a simple drug-inducible system in response to a steady
level of inducer. Using fluorescence correlation spectroscopy, we measured in
real time within a single bacterium the transcription activity at the RNA level
of the acrAB-TolC multidrug efflux pump system. When cells are exposed to constant
level of anhydrotetracycline inducer and are adsorbed onto a poly-L-lysine-coated
surface, we found that the acrAB-TolC promoter is steadily active. We also monitored
the activity of the tet promoter to characterize the effect of this efflux system
on the dynamics of drug-inducible transcription. We found that the transcriptional
response of the tet promoter to a steady level of aTc rises and then falls back
to its preinduction level. The rate of RNA degradation was constant throughout
the transcriptional pulse, indicating that the modulation of intracellular inducer
concentration alone can produce this pulsating response. Single-cell experiments
together with numerical simulations suggest that such pulsating response in drug-inducible
genetic systems is a property emerging from the dependence of drug-inducible transcription
on multidrug efflux systems.

text: Control of physical simulation has become a popular topic in the field of
computer graphics. Keyframe control has been applied to simulations of rigid bodies,
smoke, liquid, flocks, and finite element-based elastic bodies. In this paper,
we create a framework for controlling systems of interacting particles -- paying
special attention to simulations of cloth and flocking behavior. We introduce
a novel integrator-swapping approximation in order to apply the adjoint method
to linearized implicit schemes appropriate for cloth simulation. This allows the
control of cloth while avoiding computationally infeasible derivative calculations.
Meanwhile, flocking control using the adjoint method is significantly more efficient
than currently-used methods for constraining group behaviors, allowing the controlled
simulation of greater numbers of agents in fewer optimization iterations.

text: Models of RNA secondary structure folding are widely used to study evolution
in theory and simulation. However, systematic studies of the parameters involved
are rare. In this paper, we study by simulation how RNA evolution is influenced
by three different factors, namely the mutation rate, scaling of the fitness function,
and distance measure. We found that for low mutation rates the qualitative evolutionary
behavior is robust with respect to the scaling of the fitness function. For efficient
mutation rates, which are close to the error threshold, scaling and distance measure
have a strong influence on the evolutionary behavior. A global distance measure
that takes sequence information additively into account lowers the error threshold.
When using a local sequence-structure alignment for the distance, we observed
a smoother evolution of the fitness over time. Finally, in addition to the well
known error threshold, we identify another threshold of the mutation rate, called
divergence threshold, where the qualitative transient behavior changes from a
localized to an exploratory search.

text: Networks of GABAergic neurons are key elements in the generation of gamma
oscillations in the brain. Computational studies suggested that the emergence
of coherent oscillations requires hyperpolarizing inhibition. Here, we show that
GABA(A) receptor-mediated inhibition in mature interneurons of the hippocampal
dentate gyrus is shunting rather than hyperpolarizing. Unexpectedly, when shunting
inhibition is incorporated into a structured interneuron network model with fast
and strong synapses, coherent oscillations emerge. In comparison to hyperpolarizing
inhibition, networks with shunting inhibition show several advantages. First,
oscillations are generated with smaller tonic excitatory drive. Second, network
frequencies are tuned to the gamma band. Finally, robustness against heterogeneity
in the excitatory drive is markedly improved. In single interneurons, shunting
inhibition shortens the interspike interval for low levels of drive but prolongs
it for high levels, leading to homogenization of neuronal firing rates. Thus,
shunting inhibition may confer increased robustness to gamma oscillations in the
brain.

text: Hyperpolarization-activated channels (Ih or HCN channels) are widely expressed
in principal neurons in the central nervous system. However, Ih in inhibitory
GABAergic interneurons is less well characterized. We examined the functional
properties of Ih in fast-spiking basket cells (BCs) of the dentate gyrus, using
hippocampal slices from 17- to 21-day-old rats. Bath application of the Ih channel
blocker ZD 7288 at a concentration of 30 microm induced a hyperpolarization of
5.7 +/- 1.5 mV, an increase in input resistance and a correlated increase in apparent
membrane time constant. ZD 7288 blocked a hyperpolarization-activated current
in a concentration-dependent manner (IC50, 1.4 microm). The effects of ZD 7288
were mimicked by external Cs+. The reversal potential of Ih was -27.4 mV, corresponding
to a Na+ to K+ permeability ratio (PNa/PK) of 0.36. The midpoint potential of
the activation curve of Ih was -83.9 mV, and the activation time constant at -120
mV was 190 ms. Single-cell expression analysis using reverse transcription followed
by quantitative polymerase chain reaction revealed that BCs coexpress HCN1 and
HCN2 subunit mRNA, suggesting the formation of heteromeric HCN1/2 channels. ZD
7288 increased the current threshold for evoking antidromic action potentials
by extracellular stimulation, consistent with the expression of Ih in BC axons.
Finally, ZD 7288 decreased the frequency of miniature inhibitory postsynaptic
currents (mIPSCs) in hippocampal granule cells, the main target cells of BCs,
to 70 +/- 4% of the control value. In contrast, the amplitude of mIPSCs was unchanged,
consistent with the presence of Ih in inhibitory terminals. In conclusion, our
results suggest that Ih channels are expressed in the somatodendritic region,
axon and presynaptic elements of fast-spiking BCs in the hippocampus.

text: The axon terminals (mossy fibers) of hippocampal dentate granule cells form
characteristic synaptic connections with large spines or excrescences of both
hilar mossy cells and CA3 pyramidal neurons. Interneurons of the hilar region
and area CA3 are also prominent targets of mossy fibers. The tracing of biocytin-filled
mossy fibers and immunolabeling of target cells with interneuron markers has revealed
that the majority of mossy fiber synapses project to gamma aminobutyric acid (GABA)-ergic
inhibitory interneurons rather than to excitatory principal cells, although the
functional implications of these quantitative differences are unclear. Following
a brief description of the "classical" mossy fiber synapse on excrescences
of CA3 pyramidal cells, the present review focuses on the contacts formed between
granule cells and GABAergic interneurons, both normally and after synaptic reorganization.
In response to deafferentation of mossy cell target cells, which include both
granule cells and interneurons, mossy fibers "sprout" new axon collaterals
that form a band of supragranular mossy fibers in the inner molecular layer of
the dentate gyrus. Although most newly formed recurrent mossy fibers establish
synapses with granule cells, there is an apparently convergent input of new mossy
fibers onto GABA-immunoreactive interneuron dendrites that traverse the inner
molecular layer. These mossy fiber-interneuron synapses in the dentate gyrus are
observed in chronically epileptic rats and may be the structural correlate of
the granule cell hyperinhibition observed in these animals in vivo. Together,
the findings reviewed here establish mossy fiber synapses as an important component
of inhibitory circuits in the hippocampus.

text: It is widely accepted that the hippocampus plays a major role in learning
and memory. The mossy fiber synapse between granule cells in the dentate gyrus
and pyramidal neurons in the CA3 region is a key component of the hippocampal
trisynaptic circuit. Recent work, partially based on direct presynaptic patch-clamp
recordings from hippocampal mossy fiber boutons, sheds light on the mechanisms
of synaptic transmission and plasticity at mossy fiber synapses. A high Na(+)
channel density in mossy fiber boutons leads to a large amplitude of the presynaptic
action potential. Together with the fast gating of presynaptic Ca(2+) channels,
this generates a large and brief presynaptic Ca(2+) influx, which can trigger
transmitter release with high efficiency and temporal precision. The large number
of release sites, the large size of the releasable pool of vesicles, and the huge
extent of presynaptic plasticity confer unique strength to this synapse, suggesting
a large impact onto the CA3 pyramidal cell network under specific behavioral conditions.
The characteristic properties of the hippocampal mossy fiber synapse may be important
for pattern separation and information storage in the dentate gyrus-CA3 cell network.

text: Rigorous analysis of synaptic transmission in the central nervous system requires
access to presynaptic terminals. However, cortical terminals have been largely
inaccessible to presynaptic patch-clamp recording, due to their small size. Using
improved patch-clamp techniques in brain slices, we recorded from mossy fiber
terminals in the CA3 region of the hippocampus, which have a diameter of 2-5 microm.
The major steps of improvement were the enhanced visibility provided by high-numerical
aperture objectives and infrared illumination, the development of vibratomes with
minimal vertical blade vibrations and the use of sucrose-based solutions for storage
and cutting. Based on these improvements, we describe a protocol that allows us
to routinely record from hippocampal mossy fiber boutons. Presynaptic recordings
can be obtained in slices from both rats and mice. Presynaptic recordings can
be also obtained in slices from transgenic mice in which terminals are labeled
with enhanced green fluorescent protein.

text: A stochastic graph game is played by two players on a game graph with probabilistic
transitions. We consider stochastic graph games with omega-regular winning conditions
specified as Rabin or Streett objectives. These games are NP-complete and coNP-complete,
respectively. The value of the game for a player at a state s given an objective
Phi is the maximal probability with which the player can guarantee the satisfaction
of Phi from s. We present a strategy-improvement algorithm to compute values in
stochastic Rabin games, where an improvement step involves solving Markov decision
processes (MDPs) and nonstochastic Rabin games. The algorithm also computes values
for stochastic Streett games but does not directly yield an optimal strategy for
Streett objectives. We then show how to obtain an optimal strategy for Streett
objectives by solving certain nonstochastic Streett games.

text: We study observation-based strategies for two-player turn-based games on graphs
with omega-regular objectives. An observation-based strategy relies on imperfect
information about the history of a play, namely, on the past sequence of observations.
Such games occur in the synthesis of a controller that does not see the private
state of the plant. Our main results are twofold. First, we give a fixed-point
algorithm for computing the set of states from which a player can win with a deterministic
observation-based strategy for any omega-regular objective. The fixed point is
computed in the lattice of antichains of state sets. This algorithm has the advantages
of being directed by the objective and of avoiding an explicit subset construction
on the game graph. Second, we give an algorithm for computing the set of states
from which a player can win with probability 1 with a randomized observation-based
strategy for a Buchi objective. This set is of interest because in the absence
of perfect information, randomized strategies are more powerful than deterministic

text: We consider two-player infinite games played on graphs. The games are concurrent,
in that at each state the players choose their moves simultaneously and independently,
and stochastic, in that the moves determine a probability distribution for the
successor state. The value of a game is the maximal probability with which a player
can guarantee the satisfaction of her objective. We show that the values of concurrent
games with w-regular objectives expressed as parity conditions can be decided
in NP boolean AND coNP. This result substantially improves the best known previous
bound of 3EXPTIME. It also shows that the full class of concurrent parity games
is no harder than the special case of turn-based stochastic reachability games,
for which NP boolean AND coNP is the best known bound. While the previous, more
restricted NP boolean AND coNP results for graph games relied on the existence
of particularly simple (pure memoryless) optimal strategies, in concurrent games
with parity objectives optimal strategies may not exist, and epsilon-optimal strategies
(which achieve the value of the game within a parameter epsilon > 0) require
in general both randomization and infinite memory. Hence our proof must rely on
a more detailed analysis of strategies and, in addition to the main result, yields
two results that are interesting on their own. First, we show that there exist
epsilon-optimal strategies that in the limit coincide with memoryless strategies;
this parallels the celebrated result of Mertens-Neyman for concurrent games with
limit-average objectives. Second, we complete the characterization of the memory
requirements for epsilon-optimal strategies for concurrent games with parity conditions,
by showing that memoryless strategies suffice for epsilon-optimality for coBachi
conditions.

text: 'We study infinite stochastic games played by two-players over a finite state
space, with objectives specified by sets of infinite traces. The games are concurrent
(players make moves simultaneously and independently), stochastic (the next state
is determined by a probability distribution that depends on the current state
and chosen moves of the players) and infinite (proceeds for infinite number of
rounds). The analysis of concurrent stochastic games can be classified into: quantitative
analysis, analyzing the optimum value of the game; and qualitative analysis, analyzing
the set of states with optimum value 1. We consider concurrent games with tail
objectives, i.e., objectives that are independent of the finite-prefix of traces,
and show that the class of tail objectives are strictly richer than the omega-regular
objectives. We develop new proof techniques to extend several properties of concurrent
games with omega-regular objectives to concurrent games with tail objectives.
We prove the positive limit-one property for tail objectives, that states for
all concurrent games if the optimum value for a player is positive for a tail
objective Phi at some state, then there is a state where the optimum value is
1 for Phi, for the player. We also show that the optimum values of zero-sum (strictly
conflicting objectives) games with tail objectives can be related to equilibrium
values of nonzero-sum (not strictly conflicting objectives) games with simpler
reachability objectives. A consequence of our analysis presents a polynomial time
reduction of the quantitative analysis of tail objectives to the qualitative analysis
for the sub-class of one-player stochastic games (Markov decision processes).'

text: 'It is commonly believed that both the average length and the frequency of
microsatellites correlate with genome size. We have estimated the frequency and
the average length for 69 perfect dinucleotide microsatellites in an insect with
an exceptionally large genome: Chorthippus biguttulus (Orthoptera, Acrididae).
Dinucleotide microsatellites are not more frequent in C. biguttulus, but repeat
arrays are 1.4 to 2 times longer than in other insect species. The average repeat
number in C. biguttulus lies in the range of higher vertebrates. Natural populations
are highly variable. At least 30 alleles per locus were found and the expected
heterozygosity is above 0.95 at all three loci studied. In contrast, the observed
heterozygosity is much lower (≤0.51), which could be caused by long null alleles.'

text: Invasive species often dramatically change native species communities by directly
and indirectly out-competing native species. We studied the direct interference
abilities of the invasive garden ant, Lasius neglectus VAN LOON, BOOMSMA &
ANDRÁSFALVY, 1990, by performing one-to-one aggression tests of L. neglectus workers
towards three native Lasius ant species that occur at the edge of a L. neglectus
supercolony in Seva, Spain. Our results show that L. neglectus is highly aggressive
against all three native Lasius species tested (L. grandis FOREL, 1909, L. emarginatus
(OLIVIER, 1792), and L. cinereus SEIFERT, 1992), expressed as a higher attack
rate of L. neglectus and behavioural dominance throughout the aggressive encounters.
Attacks of L. neglectus were performed fastest and most frequent against L. grandis,
and also the highest antennation frequencies were observed in encounters between
these two species. This could be due to the largest difference in body size, or
due to a greater overlap in ecological niche between L. neglectus and L. grandis
compared to the other two native species. There was only weak support for L. neglectus
workers from the periphery of the supercolony to be more aggressive relative to
workers from the centre, even though the former encounter native ant species on
a daily basis at the edge of the supercolony.

text: Many invasive ant species, such as the Argentine ant or the red imported fire
ant, have huge colonies with thousands of mass-foraging workers, which quickly
monopolise resources and therefore represent a considerable threat to the native
ant fauna. Cardiocondyla obscurior and several other species of this myrmicine
genus have similarly been transferred throughout the tropics by human activities.
However, because their colonies are tiny and workers forage solitarily, Cardiocondyla
are often not recognized as successful invaders. Here, we document that the life
history of Cardiocondyla closely resembles that of the more conspicuous tramp
species, with polygyny, intranidal mating, budding, worker sterility, low genetic
variability, and possibly also unicoloniality. Given that introduced Cardiocondyla
may locally reach a very high population density, the effects of these stealthy
invaders on the native arthropod fauna should receive more attention.

text: We compare the performances of established means of character selection for
discriminant analysis in species distinction with a combination procedure for
finding the optimal character combination (minimum classification error, minimum
number of required characters), using morphometric data sets from the ant genera
Cardiocondyla, Lasius and Tetramorium. The established methods are empirical character
selection as well as forward selection, backward elimination and stepwise selection
of discriminant analysis. The combination procedure is clearly superior to the
established methods of character selection, and is widely applicable.
