text: 'A constrained pseudorandom function F: K × X → Y for a family T ⊆ 2X of subsets
of X is a function where for any key k ∈ K and set S ∈ T one can efficiently compute
a constrained key kS which allows to evaluate F (k, ·) on all inputs x ∈ S, while
even given this key, the outputs on all inputs x ∉ S look random. At Asiacrypt’13
Boneh and Waters gave a construction which supports the most general set family
so far. Its keys kc are defined for sets decided by boolean circuits C and enable
evaluation of the PRF on any x ∈ X where C(x) = 1. In their construction the PRF
input length and the size of the circuits C for which constrained keys can be
computed must be fixed beforehand during key generation. We construct a constrained
PRF that has an unbounded input length and whose constrained keys can be defined
for any set recognized by a Turing machine. The only a priori bound we make is
on the description size of the machines. We prove our construction secure assuming
publiccoin differing-input obfuscation. As applications of our constrained PRF
we build a broadcast encryption scheme where the number of potential receivers
need not be fixed at setup (in particular, the length of the keys is independent
of the number of parties) and the first identity-based non-interactive key exchange
protocol with no bound on the number of parties that can agree on a shared key.'

text: 'Bitmap images of arbitrary dimension may be formally perceived as unions
of m-dimensional boxes aligned with respect to a rectangular grid in ℝm. Cohomology
and homology groups are well known topological invariants of such sets. Cohomological
operations, such as the cup product, provide higher-order algebraic topological
invariants, especially important for digital images of dimension higher than 3.
If such an operation is determined at the level of simplicial chains [see e.g.
González-Díaz, Real, Homology, Homotopy Appl, 2003, 83-93], then it is effectively
computable. However, decomposing a cubical complex into a simplicial one deleteriously
affects the efficiency of such an approach. In order to avoid this overhead, a
direct cubical approach was applied in [Pilarczyk, Real, Adv. Comput. Math., 2015,
253-275] for the cup product in cohomology, and implemented in the ChainCon software
package [http://www.pawelpilarczyk.com/chaincon/]. We establish a formula for
the Steenrod square operations [see Steenrod, Annals of Mathematics. Second Series,
1947, 290-320] directly at the level of cubical chains, and we prove the correctness
of this formula. An implementation of this formula is programmed in C++ within
the ChainCon software framework. We provide a few examples and discuss the effectiveness
of this approach. One specific application follows from the fact that Steenrod
squares yield tests for the topological extension problem: Can a given map A →
Sd to a sphere Sd be extended to a given super-complex X of A? In particular,
the ROB-SAT problem, which is to decide for a given function f: X → ℝm and a value
r > 0 whether every g: X → ℝm with ∥g - f ∥∞ ≤ r has a root, reduces to the
extension problem.'

text: The dynamic localization of endosomal compartments labeled with targeted fluorescent
protein tags is routinely followed by time lapse fluorescence microscopy approaches
and single particle tracking algorithms. In this way trajectories of individual
endosomes can be mapped and linked to physiological processes as cell growth.
However, other aspects of dynamic behavior including endosomal interactions are
difficult to follow in this manner. Therefore, we characterized the localization
and dynamic properties of early and late endosomes throughout the entire course
of root hair formation by means of spinning disc time lapse imaging and post-acquisition
automated multitracking and quantitative analysis. Our results show differential
motile behavior of early and late endosomes and interactions of late endosomes
that may be specified to particular root hair domains. Detailed data analysis
revealed a particular transient interaction between late endosomes—termed herein
as dancing-endosomes—which is not concluding to vesicular fusion. Endosomes preferentially
located in the root hair tip interacted as dancing-endosomes and traveled short
distances during this interaction. Finally, sizes of early and late endosomes
were addressed by means of super-resolution structured illumination microscopy
(SIM) to corroborate measurements on the spinning disc. This is a first study
providing quantitative microscopic data on dynamic spatio-temporal interactions
of endosomes during root hair tip growth.

text: Nonadherent polarized cells have been observed to have a pearlike, elongated
shape. Using a minimal model that describes the cell cortex as a thin layer of
contractile active gel, we show that the anisotropy of active stresses, controlled
by cortical viscosity and filament ordering, can account for this morphology.
The predicted shapes can be determined from the flow pattern only; they prove
to be independent of the mechanism at the origin of the cortical flow, and are
only weakly sensitive to the cytoplasmic rheology. In the case of actin flows
resulting from a contractile instability, we propose a phase diagram of three-dimensional
cell shapes that encompasses nonpolarized spherical, elongated, as well as oblate
shapes, all of which have been observed in experiment.

text: 'Background: Long non-coding RNAs (lncRNAs) are increasingly implicated as
gene regulators and may ultimately be more numerous than protein-coding genes
in the human genome. Despite large numbers of reported lncRNAs, reference annotations
are likely incomplete due to their lower and tighter tissue-specific expression
compared to mRNAs. An unexplored factor potentially confounding lncRNA identification
is inter-individual expression variability. Here, we characterize lncRNA natural
expression variability in human primary granulocytes. Results: We annotate granulocyte
lncRNAs and mRNAs in RNA-seq data from 10 healthy individuals, identifying multiple
lncRNAs absent from reference annotations, and use this to investigate three known
features (higher tissue-specificity, lower expression, and reduced splicing efficiency)
of lncRNAs relative to mRNAs. Expression variability was examined in seven individuals
sampled three times at 1- or more than 1-month intervals. We show that lncRNAs
display significantly more inter-individual expression variability compared to
mRNAs. We confirm this finding in two independent human datasets by analyzing
multiple tissues from the GTEx project and lymphoblastoid cell lines from the
GEUVADIS project. Using the latter dataset we also show that including more human
donors into the transcriptome annotation pipeline allows identification of an
increasing number of lncRNAs, but minimally affects mRNA gene number. Conclusions:
A comprehensive annotation of lncRNAs is known to require an approach that is
sensitive to low and tight tissue-specific expression. Here we show that increased
inter-individual expression variability is an additional general lncRNA feature
to consider when creating a comprehensive annotation of human lncRNAs or proposing
their use as prognostic or disease markers.'

text: 'How likely is it that a population escapes extinction through adaptive evolution?
The answer to this question is of great relevance in conservation biology, where
we aim at species’ rescue and the maintenance of biodiversity, and in agriculture
and medicine, where we seek to hamper the emergence of pesticide or drug resistance.
By reshuffling the genome, recombination has two antagonistic effects on the probability
of evolutionary rescue: It generates and it breaks up favorable gene combinations.
Which of the two effects prevails depends on the fitness effects of mutations
and on the impact of stochasticity on the allele frequencies. In this article,
we analyze a mathematical model for rescue after a sudden environmental change
when adaptation is contingent on mutations at two loci. The analysis reveals a
complex nonlinear dependence of population survival on recombination. We moreover
find that, counterintuitively, a fast eradication of the wild type can promote
rescue in the presence of recombination. The model also shows that two-step rescue
is not unlikely to happen and can even be more likely than single-step rescue
(where adaptation relies on a single mutation), depending on the circumstances.'

text: A crucial step in the regulation of gene expression is binding of transcription
factor (TF) proteins to regulatory sites along the DNA. But transcription factors
act at nanomolar concentrations, and noise due to random arrival of these molecules
at their binding sites can severely limit the precision of regulation. Recent
work on the optimization of information flow through regulatory networks indicates
that the lower end of the dynamic range of concentrations is simply inaccessible,
overwhelmed by the impact of this noise. Motivated by the behavior of homeodomain
proteins, such as the maternal morphogen Bicoid in the fruit fly embryo, we suggest
a scheme in which transcription factors also act as indirect translational regulators,
binding to the mRNA of other regulatory proteins. Intuitively, each mRNA molecule
acts as an independent sensor of the input concentration, and averaging over these
multiple sensors reduces the noise. We analyze information flow through this scheme
and identify conditions under which it outperforms direct transcriptional regulation.
Our results suggest that the dual role of homeodomain proteins is not just a historical
accident, but a solution to a crucial physics problem in the regulation of gene
expression.

text: Restriction-modification (RM) systems represent a minimal and ubiquitous biological
system of self/non-self discrimination in prokaryotes [1], which protects hosts
from exogenous DNA [2]. The mechanism is based on the balance between methyltransferase
(M) and cognate restriction endonuclease (R). M tags endogenous DNA as self by
methylating short specific DNA sequences called restriction sites, whereas R recognizes
unmethylated restriction sites as non-self and introduces a double-stranded DNA
break [3]. Restriction sites are significantly underrepresented in prokaryotic
genomes [4-7], suggesting that the discrimination mechanism is imperfect and occasionally
leads to autoimmunity due to self-DNA cleavage (self-restriction) [8]. Furthermore,
RM systems can promote DNA recombination [9] and contribute to genetic variation
in microbial populations, thus facilitating adaptive evolution [10]. However,
cleavage of self-DNA by RM systems as elements shaping prokaryotic genomes has
not been directly detected, and its cause, frequency, and outcome are unknown.
We quantify self-restriction caused by two RM systems of Escherichia coli and
find that, in agreement with levels of restriction site avoidance, EcoRI, but
not EcoRV, cleaves self-DNA at a measurable rate. Self-restriction is a stochastic
process, which temporarily induces the SOS response, and is followed by DNA repair,
maintaining cell viability. We find that RM systems with higher restriction efficiency
against bacteriophage infections exhibit a higher rate of self-restriction, and
that this rate can be further increased by stochastic imbalance between R and
M. Our results identify molecular noise in RM systems as a factor shaping prokaryotic
genomes.

text: Cell polarity refers to a functional spatial organization of proteins that
is crucial for the control of essential cellular processes such as growth and
division. To establish polarity, cells rely on elaborate regulation networks that
control the distribution of proteins at the cell membrane. In fission yeast cells,
a microtubule-dependent network has been identified that polarizes the distribution
of signaling proteins that restricts growth to cell ends and targets the cytokinetic
machinery to the middle of the cell. Although many molecular components have been
shown to play a role in this network, it remains unknown which molecular functionalities
are minimally required to establish a polarized protein distribution in this system.
Here we show that a membrane-binding protein fragment, which distributes homogeneously
in wild-type fission yeast cells, can be made to concentrate at cell ends by attaching
it to a cytoplasmic microtubule end-binding protein. This concentration results
in a polarized pattern of chimera proteins with a spatial extension that is very
reminiscent of natural polarity patterns in fission yeast. However, chimera levels
fluctuate in response to microtubule dynamics, and disruption of microtubules
leads to disappearance of the pattern. Numerical simulations confirm that the
combined functionality of membrane anchoring and microtubule tip affinity is in
principle sufficient to create polarized patterns. Our chimera protein may thus
represent a simple molecular functionality that is able to polarize the membrane,
onto which additional layers of molecular complexity may be built to provide the
temporal robustness that is typical of natural polarity patterns.

text: 'To facilitate collaboration in massive online classrooms, instructors must
make many decisions. For instance, the following parameters need to be decided
when designing a peer-feedback system where students review each others'' essays:
the number of students each student must provide feedback to, an algorithm to
map feedback providers to receivers, constraints that ensure students do not become
free-riders (receiving feedback but not providing it), the best times to receive
feedback to improve learning etc. While instructors can answer these questions
by running experiments or invoking past experience, game-theoretic models with
data from online learning platforms can identify better initial designs for further
improvements. As an example, we explore the design space of a peer feedback system
by modeling it using game theory. Our simulations show that incentivizing students
to provide feedback requires the value obtained from receiving a feedback to exceed
the cost of providing it by a large factor (greater than 7). Furthermore, hiding
feedback from low-effort students incentivizes them to provide more feedback.'

text: Near-field imaging is a powerful tool to investigate the complex structure
of light at the nanoscale. Recent advances in near-field imaging have indicated
the possibility for the complete reconstruction of both electric and magnetic
components of the evanescent field. Here we study the electro-magnetic field structure
of surface plasmon polariton waves propagating along subwavelength gold nanowires
by performing phase- and polarization-resolved near-field microscopy in collection
mode. By applying the optical reciprocity theorem, we describe the signal collected
by the probe as an overlap integral of the nanowire's evanescent field and the
probe's response function. As a result, we find that the probe's sensitivity to
the magnetic field is approximately equal to its sensitivity to the electric field.
Through rigorous modeling of the nanowire mode as well as the aperture probe response
function, we obtain a good agreement between experimentally measured signals and
a numerical model. Our findings provide a better understanding of aperture-based
near-field imaging of the nanoscopic plasmonic and photonic structures and are
helpful for the interpretation of future near-field experiments.

text: The shaping of organs in plants depends on the intercellular flow of the phytohormone
auxin, of which the directional signaling is determined by the polar subcellular
localization of PIN-FORMED (PIN) auxin transport proteins. Phosphorylation dynamics
of PIN proteins are affected by the protein phosphatase 2A (PP2A) and the PINOID
kinase, which act antagonistically to mediate their apical-basal polar delivery.
Here, we identified the ROTUNDA3 (RON3) protein as a regulator of the PP2A phosphatase
activity in Arabidopsis thaliana. The RON3 gene was map-based cloned starting
from the ron3-1 leaf mutant and found to be a unique, plant-specific gene coding
for a protein with high and dispersed proline content. The ron3-1 and ron3-2 mutant
phenotypes [i.e., reduced apical dominance, primary root length, lateral root
emergence, and growth; increased ectopic stages II, IV, and V lateral root primordia;
decreased auxin maxima in indole-3-acetic acid (IAA)-treated root apical meristems;
hypergravitropic root growth and response; increased IAA levels in shoot apices;
and reduced auxin accumulation in root meristems] support a role for RON3 in auxin
biology. The affinity-purified PP2A complex with RON3 as bait suggested that RON3
might act in PIN transporter trafficking. Indeed, pharmacological interference
with vesicle trafficking processes revealed that single ron3-2 and double ron3-2
rcn1 mutants have altered PIN polarity and endocytosis in specific cells. Our
data indicate that RON3 contributes to auxin-mediated development by playing a
role in PIN recycling and polarity establishment through regulation of the PP2A
complex activity.

text: Life depends as much on the flow of information as on the flow of energy.
Here we review the many efforts to make this intuition precise. Starting with
the building blocks of information theory, we explore examples where it has been
possible to measure, directly, the flow of information in biological networks,
or more generally where information-theoretic ideas have been used to guide the
analysis of experiments. Systems of interest range from single molecules (the
sequence diversity in families of proteins) to groups of organisms (the distribution
of velocities in flocks of birds), and all scales in between. Many of these analyses
are motivated by the idea that biological systems may have evolved to optimize
the gathering and representation of information, and we review the experimental
evidence for this optimization, again across a wide range of scales.

text: 'Actin and myosin assemble into a thin layer of a highly dynamic network underneath
the membrane of eukaryotic cells. This network generates the forces that drive
cell- and tissue-scale morphogenetic processes. The effective material properties
of this active network determine large-scale deformations and other morphogenetic
events. For example, the characteristic time of stress relaxation (the Maxwell
time τM) in the actomyosin sets the timescale of large-scale deformation of the
cortex. Similarly, the characteristic length of stress propagation (the hydrodynamic
length λ) sets the length scale of slow deformations, and a large hydrodynamic
length is a prerequisite for long-ranged cortical flows. Here we introduce a method
to determine physical parameters of the actomyosin cortical layer in vivo directly
from laser ablation experiments. For this we investigate the cortical response
to laser ablation in the one-cell-stage Caenorhabditis elegans embryo and in the
gastrulating zebrafish embryo. These responses can be interpreted using a coarse-grained
physical description of the cortex in terms of a two-dimensional thin film of
an active viscoelastic gel. To determine the Maxwell time τM, the hydrodynamic
length λ, the ratio of active stress ζΔμ, and per-area friction γ, we evaluated
the response to laser ablation in two different ways: by quantifying flow and
density fields as a function of space and time, and by determining the time evolution
of the shape of the ablated region. Importantly, both methods provide best-fit
physical parameters that are in close agreement with each other and that are similar
to previous estimates in the two systems. Our method provides an accurate and
robust means for measuring physical parameters of the actomyosin cortical layer.
It can be useful for investigations of actomyosin mechanics at the cellular-scale,
but also for providing insights into the active mechanics processes that govern
tissue-scale morphogenesis.'

text: In bacteria, replicative aging manifests as a difference in growth or survival
between the two cells emerging from division. One cell can be regarded as an aging
mother with a decreased potential for future survival and division, the other
as a rejuvenated daughter. Here, we aimed at investigating some of the processes
involved in aging in the bacterium Escherichia coli, where the two types of cells
can be distinguished by the age of their cell poles. We found that certain changes
in the regulation of the carbohydrate metabolism can affect aging. A mutation
in the carbon storage regulator gene, csrA, leads to a dramatically shorter replicative
lifespan; csrA mutants stop dividing once their pole exceeds an age of about five
divisions. These old-pole cells accumulate glycogen at their old cell poles; after
their last division, they do not contain a chromosome, presumably because of spatial
exclusion by the glycogen aggregates. The new-pole daughters produced by these
aging mothers are born young; they only express the deleterious phenotype once
their pole is old. These results demonstrate how manipulations of nutrient allocation
can lead to the exclusion of the chromosome and limit replicative lifespan in
E. coli, and illustrate how mutations can have phenotypic effects that are specific
for cells with old poles. This raises the question how bacteria can avoid the
accumulation of such mutations in their genomes over evolutionary times, and how
they can achieve the long replicative lifespans that have recently been reported.

text: Plant growth and architecture is regulated by the polar distribution of the
hormone auxin. Polarity and flexibility of this process is provided by constant
cycling of auxin transporter vesicles along actin filaments, coordinated by a
positive auxinactin feedback loop. Both polar auxin transport and vesicle cycling
are inhibited by synthetic auxin transport inhibitors, such as 1-Nnaphthylphthalamic
acid (NPA), counteracting the effect of auxin; however, underlying targets and
mechanisms are unclear. Using NMR, we map the NPA binding surface on the Arabidopsis
thaliana ABCB chaperone TWISTED DWARF1 (TWD1).We identify ACTIN7 as a relevant,
although likely indirect, TWD1 interactor, and show TWD1-dependent regulation
of actin filament organization and dynamics and that TWD1 is required for NPA-mediated
actin cytoskeleton remodeling. The TWD1-ACTIN7 axis controls plasma membrane presence
of efflux transporters, and as a consequence act7 and twd1 share developmental
and physiological phenotypes indicative of defects in auxin transport. These can
be phenocopied by NPA treatment or by chemical actin (de)stabilization. We provide
evidence that TWD1 determines downstreamlocations of auxin efflux transporters
by adjusting actin filament debundling and dynamizing processes and mediating
NPA action on the latter. This function appears to be evolutionary conserved since
TWD1 expression in budding yeast alters actin polarization and cell polarity and
provides NPA sensitivity.

text: We study the homomorphism induced in homology by a closed correspondence between
topological spaces, using projections from the graph of the correspondence to
its domain and codomain. We provide assumptions under which the homomorphism induced
by an outer approximation of a continuous map coincides with the homomorphism
induced in homology by the map. In contrast to more classical results we do not
require that the projection to the domain have acyclic preimages. Moreover, we
show that it is possible to retrieve correct homological information from a correspondence
even if some data is missing or perturbed. Finally, we describe an application
to combinatorial maps that are either outer approximations of continuous maps
or reconstructions of such maps from a finite set of data points.

text: We use rigorous numerical techniques to compute a lower bound for the exponent
of expansivity outside a neighborhood of the critical point for thousands of intervals
of parameter values in the quadratic family. We first compute a radius of the
critical neighborhood outside which the map is uniformly expanding. This radius
is taken as small as possible, yet large enough for our numerical procedure to
succeed in proving that the expansivity exponent outside this neighborhood is
positive. Then, for each of the intervals, we compute a lower bound for this expansivity
exponent, valid for all the parameters in that interval. We illustrate and study
the distribution of the radii and the expansivity exponents. The results of our
computations are mathematically rigorous. The source code of the software and
the results of the computations are made publicly available at http://www.pawelpilarczyk.com/quadratic/.

text: Down syndrome cell adhesion molecule 1 (Dscam1) has widereaching and vital
neuronal functions although the role it plays in insect and crustacean immunity
is less well understood. In this study, we combine different approaches to understand
the roles that Dscam1 plays in fitness-related contexts in two model insect species.
Contrary to our expectations, we found no short-term modulation of Dscam1 gene
expression after haemocoelic or oral bacterial exposure in Tribolium castaneum,
or after haemocoelic bacterial exposure in Drosophila melanogaster. Furthermore,
RNAi-mediated Dscam1 knockdown and subsequent bacterial exposure did not reduce
T. castaneum survival. However, Dscam1 knockdown in larvae resulted in adult locomotion
defects, as well as dramatically reduced fecundity in males and females. We suggest
that Dscam1 does not always play a straightforward role in immunity, but strongly
influences behaviour and fecundity. This study takes a step towards understanding
more about the role of this intriguing gene from different phenotypic perspectives.
