text: 'Cytokinin is a phytohormone that is well known for its roles in numerous
plant growth and developmental processes, yet it has also been linked to abiotic
stress response in a less defined manner. Arabidopsis (Arabidopsis thaliana) Cytokinin
Response Factor 6 (CRF6) is a cytokinin-responsive AP2/ERF-family transcription
factor that, through the cytokinin signaling pathway, plays a key role in the
inhibition of dark-induced senescence. CRF6 expression is also induced by oxidative
stress, and here we show a novel function for CRF6 in relation to oxidative stress
and identify downstream transcriptional targets of CRF6 that are repressed in
response to oxidative stress. Analysis of transcriptomic changes in wild-type
and crf6 mutant plants treated with H2O2 identified CRF6-dependent differentially
expressed transcripts, many of which were repressed rather than induced. Moreover,
many repressed genes also show decreased expression in 35S:CRF6 overexpressing
plants. Together, these findings suggest that CRF6 functions largely as a transcriptional
repressor. Interestingly, among the H2O2 repressed CRF6-dependent transcripts
was a set of five genes associated with cytokinin processes: (signaling) ARR6,
ARR9, ARR11, (biosynthesis) LOG7, and (transport) ABCG14. We have examined mutants
of these cytokinin-associated target genes to reveal novel connections to oxidative
stress. Further examination of CRF6-DNA interactions indicated that CRF6 may regulate
its targets both directly and indirectly. Together, this shows that CRF6 functions
during oxidative stress as a negative regulator to control this cytokinin-associated
module of CRF6- dependent genes and establishes a novel connection between cytokinin
and oxidative stress response.'

text: Antibiotic-sensitive and -resistant bacteria coexist in natural environments
with low, if detectable, antibiotic concentrations. Except possibly around localized
antibiotic sources, where resistance can provide a strong advantage, bacterial
fitness is dominated by stresses unaffected by resistance to the antibiotic. How
do such mixed and heterogeneous conditions influence the selective advantage or
disadvantage of antibiotic resistance? Here we find that sub-inhibitory levels
of tetracyclines potentiate selection for or against tetracycline resistance around
localized sources of almost any toxin or stress. Furthermore, certain stresses
generate alternating rings of selection for and against resistance around a localized
source of the antibiotic. In these conditions, localized antibiotic sources, even
at high strengths, can actually produce a net selection against resistance to
the antibiotic. Our results show that interactions between the effects of an antibiotic
and other stresses in inhomogeneous environments can generate pervasive, complex
patterns of selection both for and against antibiotic resistance.

text: Social dilemmas force players to balance between personal and collective gain.
In many dilemmas, such as elected governments negotiating climate-change mitigation
measures, the decisions are made not by individual players but by their representatives.
However, the behaviour of representatives in social dilemmas has not been investigated
experimentally. Here inspired by the negotiations for greenhouse-gas emissions
reductions, we experimentally study a collective-risk social dilemma that involves
representatives deciding on behalf of their fellow group members. Representatives
can be re-elected or voted out after each consecutive collective-risk game. Selfish
players are preferentially elected and are hence found most frequently in the
"representatives" treatment. Across all treatments, we identify the
selfish players as extortioners. As predicted by our mathematical model, their
steadfast strategies enforce cooperation from fair players who finally compensate
almost completely the deficit caused by the extortionate co-players. Everybody
gains, but the extortionate representatives and their groups gain the most.

text: Hippocampal neurons encode a cognitive map of space. These maps are thought
to be updated during learning and in response to changes in the environment through
activity-dependent synaptic plasticity. Here we examine how changes in activity
influence spatial coding in rats using halorhodopsin-mediated, spatially selective
optogenetic silencing. Halorhoposin stimulation leads to light-induced suppression
in many place cells and interneurons; some place cells increase their firing through
disinhibition, whereas some show no effect. We find that place fields of the unaffected
subpopulation remain stable. On the other hand, place fields of suppressed place
cells were unstable, showing remapping across sessions before and after optogenetic
inhibition. Disinhibited place cells had stable maps but sustained an elevated
firing rate. These findings suggest that place representation in the hippocampus
is constantly governed by activity-dependent processes, and that disinhibition
may provide a mechanism for rate remapping.

text: In this paper we review various automata-theoretic formalisms for expressing
quantitative properties. We start with finite-state Boolean automata that express
the traditional regular properties. We then consider weighted ω-automata that
can measure the average density of events, which finite-state Boolean automata
cannot. However, even weighted ω-automata cannot express basic performance properties
like average response time. We finally consider two formalisms of weighted ω-automata
with monitors, where the monitors are either (a) counters or (b) weighted automata
themselves. We present a translation result to establish that these two formalisms
are equivalent. Weighted ω-automata with monitors generalize weighted ω-automata,
and can express average response time property. They present a natural, robust,
and expressive framework for quantitative specifications, with important decidable
properties.

text: 'Background: Anticancer vaccines could represent a valuable complementary
strategy to established therapies, especially in settings of early stage and minimal
residual disease. HER-2 is an important target for immunotherapy and addressed
by the monoclonal antibody trastuzumab. We have previously generated HER-2 mimotope
peptides from phage display libraries. The synthesized peptides were coupled to
carriers and applied for epitope-specific induction of trastuzumab-like IgG. For
simplification and to avoid methodological limitations of synthesis and coupling
chemistry, we herewith present a novel and optimized approach by using adeno-associated
viruses (AAV) as effective and high-density mimotope-display system, which can
be directly used for vaccination. Methods: An AAV capsid display library was constructed
by genetically incorporating random peptides in a plasmid encoding the wild-type
AAV2 capsid protein. AAV clones, expressing peptides specifically reactive to
trastuzumab, were employed to immunize BALB/c mice. Antibody titers against human
HER-2 were determined, and the isotype composition and functional properties of
these were tested. Finally, prophylactically immunized mice were challenged with
human HER-2 transfected mouse D2F2/E2 cells. Results: HER-2 mimotope AAV-vaccines
induced antibodies specific to human HER-2. Two clones were selected for immunization
of mice, which were subsequently grafted D2F2/E2 cells. Both mimotope AAV clones
delayed the growth of tumors significantly, as compared to controls. Conclusion:
In this study, a novel mimotope AAV-based platform was created allowing the isolation
of mimotopes, which can be directly used as anticancer vaccines. The example of
trastuzumab AAV-mimotopes demonstrates that this vaccine strategy could help to
establish active immunotherapy for breast-cancer patients.'

text: The integration of social networking concepts into Internet of Things systems
is a burgeoning topic of research that promises to support novel and more powerful
applications. In this paper we focus on the design and implementation of a highly
scalable Trust and Reputation Model for the Internet of Things based on the social
approach that the COSMOS project introduces, as part of its final results. We
create our model by combining popular solutions proposed for Peer-to-Peer and
mobile ad-hoc networks and adapting them on the Internet of Things concept. Each
Thing can compute the Trust index of another Thing based on its own experiences,
while it has the capability of determining its Reputation Index either by consulting
its other “friends” (Followees) or referring to the Platform, a management system
used in COSMOS. The model is tested through simulations of the proposed social
system, demonstrating the ability of TRM-SIoT to achieve the Social Exclusion
of malicious nodes and collectives from the network, with low computational overhead
and high scalability. Furthermore, due to the adaptive nature of the system, Social
Reintegration of these nodes is also possible.

text: While showing great promise, Bitcoin requires users to wait tens of minutes
for transactions to commit, and even then, offering only probabilistic guarantees.
This paper introduces ByzCoin, a novel Byzantine consensus protocol that leverages
scalable collective signing to commit Bitcoin transactions irreversibly within
seconds. ByzCoin achieves Byzantine consensus while preserving Bitcoin’s open
membership by dynamically forming hash power-proportionate consensus groups that
represent recently-successful block miners. ByzCoin employs communication trees
to optimize transaction commitment and verification under normal operation while
guaranteeing safety and liveness under Byzantine faults, up to a near-optimal
tolerance of f faulty group members among 3f + 2 total. ByzCoin mitigates double
spending and selfish mining attacks by producing collectively signed transaction
blocks within one minute of transaction submission. Tree-structured communication
further reduces this latency to less than 30 seconds. Due to these optimizations,
ByzCoin achieves a throughput higher than Paypal currently handles, with a confirmation
latency of 15-20 seconds.

text: During spore formation in Bacillus subtilis a transenvelope complex is assembled
across the double membrane that separates the mother cell and forespore. This
complex (called the “A–Q complex”) is required to maintain forespore development
and is composed of proteins with remote homology to components of type II, III,
and IV secretion systems found in Gram-negative bacteria. Here, we show that one
of these proteins, SpoIIIAG, which has remote homology to ring-forming proteins
found in type III secretion systems, assembles into an oligomeric ring in the
periplasmic-like space between the two membranes. Three-dimensional reconstruction
of images generated by cryo-electron microscopy indicates that the SpoIIIAG ring
has a cup-and-saucer architecture with a 6-nm central pore. Structural modeling
of SpoIIIAG generated a 24-member ring with dimensions similar to those of the
EM-derived saucer. Point mutations in the predicted oligomeric interface disrupted
ring formation in vitro and impaired forespore gene expression and efficient spore
formation in vivo. Taken together, our data provide strong support for the model
in which the A–Q transenvelope complex contains a conduit that connects the mother
cell and forespore. We propose that a set of stacked rings spans the intermembrane
space, as has been found for type III secretion systems.

text: Transverse relaxation rate measurements in magic-angle spinning solid-state
nuclear magnetic resonance provide information about molecular motions occurring
on nanosecond-to-millisecond (ns–ms) time scales. The measurement of heteronuclear
(13C, 15N) relaxation rate constants in the presence of a spin-lock radiofrequency
field (R1ρ relaxation) provides access to such motions, and an increasing number
of studies involving R1ρ relaxation in proteins have been reported. However, two
factors that influence the observed relaxation rate constants have so far been
neglected, namely, (1) the role of CSA/dipolar cross-correlated relaxation (CCR)
and (2) the impact of fast proton spin flips (i.e., proton spin diffusion and
relaxation). We show that CSA/D CCR in R1ρ experiments is measurable and that
the CCR rate constant depends on ns–ms motions; it can thus provide insight into
dynamics. We find that proton spin diffusion attenuates this CCR due to its decoupling
effect on the doublet components. For measurements of dynamics, the use of R1ρ
rate constants has practical advantages over the use of CCR rates, and this article
reveals factors that have so far been disregarded and which are important for
accurate measurements and interpretation.

text: Magic-angle spinning solid-state NMR spectroscopy is an important technique
to study molecular structure, dynamics and interactions, and is rapidly gaining
importance in biomolecular sciences. Here we provide an overview of experimental
approaches to study molecular dynamics by MAS solid-state NMR, with an emphasis
on the underlying theoretical concepts and differences of MAS solid-state NMR
compared to solution-state NMR. The theoretical foundations of nuclear spin relaxation
are revisited, focusing on the particularities of spin relaxation in solid samples
under magic-angle spinning. We discuss the range of validity of Redfield theory,
as well as the inherent multi-exponential behavior of relaxation in solids. Experimental
challenges for measuring relaxation parameters in MAS solid-state NMR and a few
recently proposed relaxation approaches are discussed, which provide information
about time scales and amplitudes of motions ranging from picoseconds to milliseconds.
We also discuss the theoretical basis and experimental measurements of anisotropic
interactions (chemical-shift anisotropies, dipolar and quadrupolar couplings),
which give direct information about the amplitude of motions. The potential of
combining relaxation data with such measurements of dynamically-averaged anisotropic
interactions is discussed. Although the focus of this review is on the theoretical
foundations of dynamics studies rather than their application, we close by discussing
a small number of recent dynamics studies, where the dynamic properties of proteins
in crystals are compared to those in solution.

text: Solid-state NMR spectroscopy allows the characterization of the structure,
interactions and dynamics of insoluble and/or very large proteins. Sensitivity
and resolution are often major challenges for obtaining atomic-resolution information,
in particular for very large protein complexes. Here we show that the use of deuterated,
specifically CH3-labelled proteins result in significant sensitivity gains compared
to previously employed CHD2 labelling, while line widths increase only marginally.
We apply this labelling strategy to a 468 kDa-large dodecameric aminopeptidase,
TET2, and the 1.6 MDa-large 50S ribosome subunit of Thermus thermophilus.

text: Understanding the principles that led to the current complexity of the genetic
code is a central question in evolution. Expansion of the genetic code required
the selection of new transfer RNAs (tRNAs) with specific recognition signals that
allowed them to be matured, modified, aminoacylated, and processed by the ribosome
without compromising the fidelity or efficiency of protein synthesis. We show
that saturation of recognition signals blocks the emergence of new tRNA identities
and that the rate of nucleotide substitutions in tRNAs is higher in species with
fewer tRNA genes. We propose that the growth of the genetic code stalled because
a limit was reached in the number of identity elements that can be effectively
used in the tRNA structure.

text: In this paper we study a so-called separatrix map introduced by Zaslavskii–Filonenko
(Sov Phys JETP 27:851–857, 1968) and studied by Treschev (Physica D 116(1–2):21–43,
1998; J Nonlinear Sci 12(1):27–58, 2002), Piftankin (Nonlinearity (19):2617–2644,
2006) Piftankin and Treshchëv (Uspekhi Mat Nauk 62(2(374)):3–108, 2007). We derive
a second order expansion of this map for trigonometric perturbations. In Castejon
et al. (Random iteration of maps of a cylinder and diffusive behavior. Preprint
available at arXiv:1501.03319, 2015), Guardia and Kaloshin (Stochastic diffusive

and Kaloshin et al. (Normally Hyperbolic Invariant Laminations and diffusive behavior
for the generalized Arnold example away from resonances. Preprint available at
http://www.terpconnect.umd.edu/vkaloshi/, 2015), applying the results of the present
paper, we describe a class of nearly integrable deterministic systems with stochastic
diffusive behavior.

text: "We prove a form of Arnold diffusion in the a-priori stable case. Let\r\nH0(p)+ϵH1(θ,p,t),θ∈Tn,p∈Bn,t∈T=R/T,\r\nbe
a nearly integrable system of arbitrary degrees of freedom n⩾2 with a strictly
convex H0. We show that for a “generic” ϵH1, there exists an orbit (θ,p) satisfying\r\n∥p(t)−p(0)∥>l(H1)>0,\r\nwhere
l(H1) is independent of ϵ. The diffusion orbit travels along a codimension-1 resonance,
and the only obstruction to our construction is a finite set of additional resonances.\r\n\r\nFor
the proof we use a combination of geometric and variational methods, and manage
to adapt tools which have recently been developed in the a-priori unstable case."

text: "We study the dynamics of the restricted planar three-body problem near mean
motion resonances, i.e. a resonance involving the Keplerian periods of the two
lighter bodies revolving around the most massive one. This problem is often used
to model Sun–Jupiter–asteroid systems. For the primaries (Sun and Jupiter), we
pick a realistic mass ratio μ=10−3 and a small eccentricity e0>0. The main result
is a construction of a variety of non local diffusing orbits which show a drastic
change of the osculating (instant) eccentricity of the asteroid, while the osculating
semi major axis is kept almost constant. The proof relies on the careful analysis
of the circular problem, which has a hyperbolic structure, but for which diffusion
is prevented by KAM tori. In the proof we verify certain non-degeneracy conditions
numerically.\r\n\r\nBased on the work of Treschev, it is natural to conjecture
that the time of diffusion for this problem is ∼−ln(μe0)μ3/2e0. We expect our
instability mechanism to apply to realistic values of e0 and we give heuristic
arguments in its favor. If so, the applicability of Nekhoroshev theory to the
three-body problem as well as the long time stability become questionable.\r\n\r\nIt
is well known that, in the Asteroid Belt, located between the orbits of Mars and
Jupiter, the distribution of asteroids has the so-called Kirkwood gaps exactly
at mean motion resonances of low order. Our mechanism gives a possible explanation
of their existence. To relate the existence of Kirkwood gaps with Arnol'd diffusion,
we also state a conjecture on its existence for a typical ϵ-perturbation of the
product of the pendulum and the rotator. Namely, we predict that a positive conditional
measure of initial conditions concentrated in the main resonance exhibits Arnol’d
diffusion on time scales −lnϵϵ2."

text: Fitness landscapes depict how genotypes manifest at the phenotypic level and
form the basis of our understanding of many areas of biology, yet their properties
remain elusive. Previous studies have analysed specific genes, often using their
function as a proxy for fitness, experimentally assessing the effect on function
of single mutations and their combinations in a specific sequence or in different
sequences. However, systematic high-throughput studies of the local fitness landscape
of an entire protein have not yet been reported. Here we visualize an extensive
region of the local fitness landscape of the green fluorescent protein from Aequorea
Victoria (avGFP) by measuring the native function (fluorescence) of tens of thousands
of derivative genotypes of avGFP. We show that the fitness landscape of avGFP
is narrow, with 3/4 of the derivatives with a single mutation showing reduced
fluorescence and half of the derivatives with four mutations being completely
non-fluorescent. The narrowness is enhanced by epistasis, which was detected in
up to 30% of genotypes with multiple mutations and mostly occurred through the
cumulative effect of slightly deleterious mutations causing a threshold-like decrease
in protein stability and a concomitant loss of fluorescence. A model of orthologous
sequence divergence spanning hundreds of millions of years predicted the extent
of epistasis in our data, indicating congruence between the fitness landscape
properties at the local and global scales. The characterization of the local fitness
landscape of avGFP has important implications for several fields including molecular
evolution, population genetics and protein design.

text: A comparative analysis of the metagenomes from two 30 000-year-old permafrost
samples, one of lake-alluvial origin and the other from late Pleistocene Ice Complex
sediments, revealed significant differences within microbial communities. The
late Pleistocene Ice Complex sediments (which have been characterized by the absence
of methane with lower values of redox potential and Fe2+ content) showed a low
abundance of methanogenic archaea and enzymes from both the carbon and nitrogen
cycles, but a higher abundance of enzymes associated with the sulfur cycle. The
metagenomic and geochemical analyses described in the paper provide evidence that
the formation of the sampled late Pleistocene Ice Complex sediments likely took
place under much more aerobic conditions than lake-alluvial sediments.

text: Multicellular eukaryotes have evolved a range of mechanisms for immune recognition.
A widespread family involved in innate immunity are the NACHT-domain and leucine-rich-repeat-containing
(NLR) proteins.Mammals have small numbers of NLR proteins, whereas in some species,
mostly those without adaptive immune systems, NLRs have expanded into very large
families.We describe a family of nearly 400NLR proteins encoded in the zebrafish
genome. The proteins share a defining overall structure, which arose in fishes
after a fusion of the core NLR domains with a B30.2 domain, but can be subdivided
into four groups based on their NACHT domains. Gene conversion acting differentially
on the NACHT and B30.2 domains has shaped the family and created the groups. Evidence
of positive selection in the B30.2 domain indicates that this domain rather than
the leucine-rich repeats acts as the pathogen recognition module. In an unusual
chromosomal organization, the majority of the genes are located on one chromosome
arm, interspersed with other large multigene families, including a new family
encoding zinc-finger proteins. The NLR-B30.2 proteins represent a new family with
diversity in the specific recognition module that is present in fishes in spite
of the parallel existence of an adaptive immune system.
