text: Transcription factors are central to sustaining pluripotency, yet little is
known about transcription factor dynamics in defining pluripotency in the early
mammalian embryo. Here, we establish a fluorescence decay after photoactivation
(FDAP) assay to quantitatively study the kinetic behaviour of Oct4, a key transcription
factor controlling pre-implantation development in the mouse embryo. FDAP measurements
reveal that each cell in a developing embryo shows one of two distinct Oct4 kinetics,
before there are any morphologically distinguishable differences or outward signs
of lineage patterning. The differences revealed by FDAP are due to differences
in the accessibility of Oct4 to its DNA binding sites in the nucleus. Lineage
tracing of the cells in the two distinct sub-populations demonstrates that the
Oct4 kinetics predict lineages of the early embryo. Cells with slower Oct4 kinetics
are more likely to give rise to the pluripotent cell lineage that contributes
to the inner cell mass. Those with faster Oct4 kinetics contribute mostly to the
extra-embryonic lineage. Our findings identify Oct4 kinetics, rather than differences
in total transcription factor expression levels, as a predictive measure of developmental
cell lineage patterning in the early mouse embryo.

text: Cell migration on two-dimensional (2D) substrates follows entirely different
rules than cell migration in three-dimensional (3D) environments. This is especially
relevant for leukocytes that are able to migrate in the absence of adhesion receptors
within the confined geometry of artificial 3D extracellular matrix scaffolds and
within the interstitial space in vivo. Here, we describe in detail a simple and
economical protocol to visualize dendritic cell migration in 3D collagen scaffolds
along chemotactic gradients. This method can be adapted to other cell types and
may serve as a physiologically relevant paradigm for the directed locomotion of
most amoeboid cells.

text: 'Small photochromic molecules are widespread in nature and serve as switches
for a plethora of light-controlled processes. In a typical photoreceptor, the
different geometries and polarities of the photochrome isomers are tightly coupled
to functionally relevant conformational changes in the proteins. The past decade
has seen extensive efforts to mimic nature and create proteins controlled by synthetic
photochromes in the laboratory. Here, we discuss the role of molecular modeling
to gain a structural understanding of photochromes and to design light-controlled
peptides and proteins. We address several fundamental questions: What are the
molecular structures of photochromes, particularly for metastable isomers that
cannot be addressed experimentally? How are the structures of bistable photoisomers
coupled to the conformational states of peptides and proteins? Can we design light-controlled
proteins rapidly and reliably? After an introduction to the principles of molecular
modeling, we answer these questions by examining systems that range from the size
of isolated photochromes, to that of peptides and large cell surface receptors,
each from its unique computational perspective.'

text: 'The pink dolphin (Inia geoffrensis) is widely distributed along the Amazon
and Orinoco basins, covering an area of approximately 7 million km2. Previous
morphological and genetic studies have proposed the existence of at least two
evolutionary significant units: one distributed across the Orinoco and Amazon
basins and another confined to the Bolivian Amazon. The presence of barriers in
the riverine environment has been suggested to play a significant role in shaping
present-day patterns of ecological and genetic structure for this species. In
the present study, we examined the phylogeographic structure, lineage divergence
time and historical demography using mitochondrial (mt)DNA sequences in different
pink dolphin populations distributed in large and small spatial scales, including
two neighbouring Brazilian Amazon populations. mtDNA control region (CR) analysis
revealed that the Brazilian haplotypes occupy an intermediate position compared
to three previously studied geographic locations: the Colombian Amazon, the Colombian
Orinoco, and the Bolivian Amazon. On a local scale, we have identified a pattern
of maternal isolation between two neighbouring populations from Brazil. Six mtDNA
CR haplotypes were identified in Brazil with no sharing between the two populations,
as well as specific cytochrome b (cyt b) haplotypes identified in each locality.
In addition, we analyzed autosomal microsatellites to investigate male-mediated
gene flow and demographic changes within the study area in Brazil. Data analysis
of 14 microsatellite loci failed to detect significant population subdivision,
suggesting that male-mediated gene flow may maintain homogeneity between these
two locations. Moreover, both mtDNA and microsatellite data indicate a major demographic
collapse within Brazil in the late Pleistocene. Bayesian skyline plots (BSP) of
mtDNA data revealed a stable population for Colombian and Brazilian Amazon lineages
through time, whereas a population decline was demonstrated in the Colombian Orinoco
lineage. Moreover, BSP and Tajima''s D and Fu''s Fs tests revealed a recent population
expansion exclusively in the Bolivian sample. Finally, we estimated that the diversification
of the Inia sp. lineage began in the Late Pliocene (approximately 3.1 Mya) and
continued throughout the Pleistocene.'

text: The small-sized frugivorous bat Carollia perspicillata is an understory specialist
and occurs in a wide range of lowland habitats, tending to be more common in tropical
dry or moist forests of South and Central America. Its sister species, Carollia
brevicauda, occurs almost exclusively in the Amazon rainforest. A recent phylogeographic
study proposed a hypothesis of origin and subsequent diversification for C. perspicillata
along the Atlantic coastal forest of Brazil. Additionally, it also found two allopatric
clades for C. brevicauda separated by the Amazon Basin. We used cytochrome b gene
sequences and a more extensive sampling to test hypotheses related to the origin
and diversification of C. perspicillata plus C. brevicauda clade in South America.
The results obtained indicate that there are two sympatric evolutionary lineages
within each species. In C. perspicillata, one lineage is limited to the Southern
Atlantic Forest, whereas the other is widely distributed. Coalescent analysis
points to a simultaneous origin for C. perspicillata and C. brevicauda, although
no place for the diversification of each species can be firmly suggested. The
phylogeographic pattern shown by C. perspicillata is also congruent with the Pleistocene
refugia hypothesis as a likely vicariant phenomenon shaping the present distribution
of its intraspecific lineages.

text: We bound the difference in length of two curves in terms of their total curvatures
and the Fréchet distance. The bound is independent of the dimension of the ambient
Euclidean space, it improves upon a bound by Cohen-Steiner and Edelsbrunner, and
it generalizes a result by Fáry and Chakerian.

text: Advanced stages of Scyllarus phyllosoma larvae were collected by demersal
trawling during fishery research surveys in the western Mediterranean Sea in 2003–2005.
Nucleotide sequence analysis of the mitochondrial 16S rDNA gene allowed the final-stage
phyllosoma of Scyllarus arctus to be identified among these larvae. Its morphology
is described and illustrated. This constitutes the second complete description
of a Scyllaridae phyllosoma with its specific identity being validated by molecular
techniques (the first was S. pygmaeus). These results also solved a long lasting
taxonomic anomaly of several species assigned to the ancient genus Phyllosoma
Leach, 1814. Detailed examination indicated that the final-stage phyllosoma of
S. arctus shows closer affinities with the American scyllarid Scyllarus depressus
or with the Australian Scyllarus sp. b (sensu Phillips et al., 1981) than to its
sympatric species S. pygmaeus.

text: During the development of multicellular organisms, cell fate specification
is followed by the sorting of different cell types into distinct domains from
where the different tissues and organs are formed. Cell sorting involves both
the segregation of a mixed population of cells with different fates and properties
into distinct domains, and the active maintenance of their segregated state. Because
of its biological importance and apparent resemblance to fluid segregation in
physics, cell sorting was extensively studied by both biologists and physicists
over the last decades. Different theories were developed that try to explain cell
sorting on the basis of the physical properties of the constituent cells. However,
only recently the molecular and cellular mechanisms that control the physical
properties driving cell sorting, have begun to be unraveled. In this review, we
will provide an overview of different cell-sorting processes in development and
discuss how these processes can be explained by the different sorting theories,
and how these theories in turn can be connected to the molecular and cellular
mechanisms driving these processes.

text: We address the problem of covering ℝ n with congruent balls, while minimizing
the number of balls that contain an average point. Considering the 1-parameter
family of lattices defined by stretching or compressing the integer grid in diagonal
direction, we give a closed formula for the covering density that depends on the
distortion parameter. We observe that our family contains the thinnest lattice
coverings in dimensions 2 to 5. We also consider the problem of packing congruent
balls in ℝ n , for which we give a closed formula for the packing density as well.
Again we observe that our family contains optimal configurations, this time densest
packings in dimensions 2 and 3.

text: 'We present a detailed study of the local density of states (LDOS) associated
with the surface-state band near a step edge of the strong topological insulator
Bi2Te3 and reveal a one-dimensional bound state that runs parallel to the step
edge and is bound to it at some characteristic distance. This bound state is clearly
observed in the bulk gap region, while it becomes entangled with the oscillations
of the warped surface band at high energy, and with the valence-band states near
the Dirac point. We obtain excellent fits to theoretical predictions [Alpichshev,
2011] that properly incorporate the three-dimensional nature of the problem to
the surface state. Fitting the data at different energies, we can recalculate
the LDOS originating from the Dirac band without the contribution of the bulk
bands or incoherent tunneling effects. '

text: The elevation function on a smoothly embedded 2-manifold in R-3 reflects the
multiscale topography of cavities and protrusions as local maxima. The function
has been useful in identifying coarse docking configurations for protein pairs.
Transporting the concept from the smooth to the piecewise linear category, this
paper describes an algorithm for finding all local maxima. While its worst-case
running time is the same as of the algorithm used in prior work, its performance
in practice is orders of magnitudes superior. We cast light on this improvement
by relating the running time to the total absolute Gaussian curvature of the 2-manifold.

text: 'Spontaneous release of glutamate is important for maintaining synaptic strength
and controlling spike timing in the brain. Mechanisms regulating spontaneous exocytosis
remain poorly understood. Extracellular calcium concentration ([Ca2+]o) regulates
Ca2+ entry through voltage-activated calcium channels (VACCs) and consequently
is a pivotal determinant of action potential-evoked vesicle fusion. Extracellular
Ca 2+ also enhances spontaneous release, but via unknown mechanisms. Here we report
that external Ca2+ triggers spontaneous glutamate release more weakly than evoked
release in mouse neocortical neurons. Blockade of VACCs has no effect on the spontaneous
release rate or its dependence on [Ca2+]o. Intracellular [Ca2+] slowly increases
in a minority of neurons following increases in [Ca2+]o. Furthermore, the enhancement
of spontaneous release by extracellular calcium is insensitive to chelation of
intracellular calcium by BAPTA. Activation of the calcium-sensing receptor (CaSR),
a G-protein-coupled receptor present in nerve terminals, by several specific agonists
increased spontaneous glutamate release. The frequency of spontaneous synaptic
transmission was decreased in CaSR mutant neurons. The concentration-effect relationship
for extracellular calcium regulation of spontaneous release was well described
by a combination of CaSR-dependent and CaSR-independent mechanisms. Overall these
results indicate that extracellular Ca2+ does not trigger spontaneous glutamate
release by simply increasing calcium influx but stimulates CaSR and thereby promotes
resting spontaneous glutamate release. '

text: In their search for antigens, lymphocytes continuously shuttle among blood
vessels, lymph vessels, and lymphatic tissues. Chemokines mediate entry of lymphocytes
into lymphatic tissues, and sphingosine 1-phosphate (S1P) promotes localization
of lymphocytes to the vasculature. Both signals are sensed through G protein-coupled
receptors (GPCRs). Most GPCRs undergo ligand-dependent homologous receptor desensitization,
a process that decreases their signaling output after previous exposure to high
ligand concentration. Such desensitization can explain why lymphocytes do not
take an intermediate position between two signals but rather oscillate between
them. The desensitization of S1P receptor 1 (S1PR1) is mediated by GPCR kinase
2 (GRK2). Deletion of GRK2 in lymphocytes compromises desensitization by high
vascular S1P concentrations, thereby reducing responsiveness to the chemokine
signal and trapping the cells in the vascular compartment. The desensitization
kinetics of S1PR1 allows lymphocytes to dynamically shuttle between vasculature
and lymphatic tissue, although the positional information in both compartments
is static.

text: Cancer stem cells or cancer initiating cells are believed to contribute to
cancer recurrence after therapy. MicroRNAs (miRNAs) are short RNA molecules with
fundamental roles in gene regulation. The role of miRNAs in cancer stem cells
is only poorly understood. Here, we report miRNA expression profiles of glioblastoma
stem cell-containing CD133 + cell populations. We find that miR-9, miR-9 * (referred
to as miR-9/9 *), miR-17 and miR-106b are highly abundant in CD133 + cells. Furthermore,
inhibition of miR-9/9 * or miR-17 leads to reduced neurosphere formation and stimulates
cell differentiation. Calmodulin-binding transcription activator 1 (CAMTA1) is
a putative transcription factor, which induces the expression of the anti-proliferative
cardiac hormone natriuretic peptide A (NPPA). We identify CAMTA1 as an miR-9/9
* and miR-17 target. CAMTA1 expression leads to reduced neurosphere formation
and tumour growth in nude mice, suggesting that CAMTA1 can function as tumour
suppressor. Consistently, CAMTA1 and NPPA expression correlate with patient survival.
Our findings could provide a basis for novel strategies of glioblastoma therapy.

text: Software transactional memories (STM) are described in the literature with
assumptions of sequentially consistent program execution and atomicity of high
level operations like read, write, and abort. However, in a realistic setting,
processors use relaxed memory models to optimize hardware performance. Moreover,
the atomicity of operations depends on the underlying hardware. This paper presents
the first approach to verify STMs under relaxed memory models with atomicity of
32 bit loads and stores, and read-modify-write operations. We describe RML, a
simple language for expressing concurrent programs. We develop a semantics of
RML parametrized by a relaxed memory model. We then present our tool, FOIL, which
takes as input the RML description of an STM algorithm restricted to two threads
and two variables, and the description of a memory model, and automatically determines
the locations of fences, which if inserted, ensure the correctness of the restricted
STM algorithm under the given memory model. We use FOIL to verify DSTM, TL2, and
McRT STM under the memory models of sequential consistency, total store order,
partial store order, and relaxed memory order for two threads and two variables.
Finally, we extend the verification results for DSTM and TL2 to an arbitrary number
of threads and variables by manually proving that the structural properties of
STMs are satisfied at the hardware level of atomicity under the considered relaxed
memory models.

text: Computing the winning set for Büchi objectives in alternating games on graphs
is a central problem in computer aided verification with a large number of applications.
The long standing best known upper bound for solving the problem is ̃O(n·m), where
n is the number of vertices and m is the number of edges in the graph. We are
the first to break the ̃O(n·m) boundary by presenting a new technique that reduces
the running time to O(n2). This bound also leads to O(n2) time algorithms for
computing the set of almost-sure winning vertices for Büchi objectives (1) in
alternating games with probabilistic transitions (improving an earlier bound of
O(n·m)), (2) in concurrent graph games with constant actions (improving an earlier
bound of O(n3)), and (3) in Markov decision processes (improving for m > n4/3
an earlier bound of O(min(m1.5, m·n2/3)). We also show that the same technique
can be used to compute the maximal end-component decomposition of a graph in time
O(n2), which is an improvement over earlier bounds for m > n4/3. Finally, we show
how to maintain the winning set for Büchi objectives in alternating games under
a sequence of edge insertions or a sequence of edge deletions in O(n) amortized
time per operation. This is the first dynamic algorithm for this problem.

text: 'We consider 2-player games played on a finite state space for an infinite
number of rounds. The games are concurrent: in each round, the two players (player
1 and player 2) choose their moves independently and simultaneously; the current
state and the two moves determine the successor state. We study concurrent games
with ω-regular winning conditions specified as parity objectives. We consider
the qualitative analysis problems: the computation of the almost-sure and limit-sure
winning set of states, where player 1 can ensure to win with probability 1 and
with probability arbitrarily close to 1, respectively. In general the almost-sure
and limit-sure winning strategies require both infinite-memory as well as infinite-precision
(to describe probabilities). We study the bounded-rationality problem for qualitative
analysis of concurrent parity games, where the strategy set for player 1 is restricted
to bounded-resource strategies. In terms of precision, strategies can be deterministic,
uniform, finite-precision or infinite-precision; and in terms of memory, strategies
can be memoryless, finite-memory or infinite-memory. We present a precise and
complete characterization of the qualitative winning sets for all combinations
of classes of strategies. In particular, we show that uniform memoryless strategies
are as powerful as finite-precision infinite-memory strategies, and infinite-precision
memoryless strategies are as powerful as infinite-precision finite-memory strategies. We
show that the winning sets can be computed in O(n2d+3) time, where n is the size
of the game structure and 2d is the number of priorities (or colors), and our
algorithms are symbolic. The membership problem of whether a state belongs to
a winning set can be decided in NP ∩ coNP. While this complexity is the same as
for the simpler class of turn-based parity games, where in each state only one
of the two players has a choice of moves, our algorithms,that are obtained by
characterization of the winning sets as μ-calculus formulas, are considerably
more involved than those for turn-based games.'

text: "In two-player finite-state stochastic games of partial obser- vation on graphs,
in every state of the graph, the players simultaneously choose an action, and
their joint actions determine a probability distri- bution over the successor
states. The game is played for infinitely many rounds and thus the players construct
an infinite path in the graph. We consider reachability objectives where the first
player tries to ensure a target state to be visited almost-surely (i.e., with
probability 1) or pos- itively (i.e., with positive probability), no matter the
strategy of the second player.\r\n\r\nWe classify such games according to the
information and to the power of randomization available to the players. On the
basis of information, the game can be one-sided with either (a) player 1, or (b)
player 2 having partial observation (and the other player has perfect observation),
or two- sided with (c) both players having partial observation. On the basis of
randomization, (a) the players may not be allowed to use randomization (pure strategies),
or (b) they may choose a probability distribution over actions but the actual
random choice is external and not visible to the player (actions invisible), or
(c) they may use full randomization.\r\n\r\nOur main results for pure strategies
are as follows: (1) For one-sided games with player 2 perfect observation we show
that (in contrast to full randomized strategies) belief-based (subset-construction
based) strate- gies are not sufficient, and present an exponential upper bound
on mem- ory both for almost-sure and positive winning strategies; we show that
the problem of deciding the existence of almost-sure and positive winning strategies
for player 1 is EXPTIME-complete and present symbolic algo- rithms that avoid
the explicit exponential construction. (2) For one-sided games with player 1 perfect
observation we show that non-elementary memory is both necessary and sufficient
for both almost-sure and posi- tive winning strategies. (3) We show that for the
general (two-sided) case finite-memory strategies are sufficient for both positive
and almost-sure winning, and at least non-elementary memory is required. We establish
the equivalence of the almost-sure winning problems for pure strategies and for
randomized strategies with actions invisible. Our equivalence re- sult exhibit
serious flaws in previous results in the literature: we show a non-elementary
memory lower bound for almost-sure winning whereas an exponential upper bound
was previously claimed."
