text: 'The question whether RM codes are capacity-achieving is a long-standing open
problem in coding theory that was recently answered in the affirmative for transmission
over erasure channels [1], [2]. Remarkably, the proof does not rely on specific
properties of RM codes, apart from their symmetry. Indeed, the main technical
result consists in showing that any sequence of linear codes, with doubly-transitive
permutation groups, achieves capacity on the memoryless erasure channel under
bit-MAP decoding. Thus, a natural question is what happens under block-MAP decoding.
In [1], [2], by exploiting further symmetries of the code, the bit-MAP threshold
was shown to be sharp enough so that the block erasure probability also converges
to 0. However, this technique relies heavily on the fact that the transmission
is over an erasure channel. We present an alternative approach to strengthen results
regarding the bit-MAP threshold to block-MAP thresholds. This approach is based
on a careful analysis of the weight distribution of RM codes. In particular, the
flavor of the main result is the following: assume that the bit-MAP error probability
decays as N -δ , for some δ > 0. Then, the block-MAP error probability also converges
to 0. This technique applies to transmission over any binary memoryless symmetric
channel. Thus, it can be thought of as a first step in extending the proof that
RM codes are capacity-achieving to the general case.'

text: We introduce a scheme for preparation, manipulation, and read out of Majorana
zero modes in semiconducting wires with mesoscopic superconducting islands. Our
approach synthesizes recent advances in materials growth with tools commonly used
in quantum-dot experiments, including gate control of tunnel barriers and Coulomb
effects, charge sensing, and charge pumping. We outline a sequence of milestones
interpolating between zero-mode detection and quantum computing that includes
(1) detection of fusion rules for non-Abelian anyons using either proximal charge
sensors or pumped current, (2) validation of a prototype topological qubit, and
(3) demonstration of non-Abelian statistics by braiding in a branched geometry.
The first two milestones require only a single wire with two islands, and additionally
enable sensitive measurements of the system\'s excitation gap, quasiparticle poisoning
rates, residual Majorana zero-mode splittings, and topological-qubit coherence
times. These pre-braiding experiments can be adapted to other manipulation and
read out schemes as well.

text: Majorana zero modes are quasiparticle excitations in condensed matter systems
that have been proposed as building blocks of fault-tolerant quantum computers.
They are expected to exhibit non-Abelian particle statistics, in contrast to the
usual statistics of fermions and bosons, enabling quantum operations to be performed
by braiding isolated modes around one another. Quantum braiding operations are
topologically protected insofar as these modes are pinned near zero energy, with
the departure from zero expected to be exponentially small as the modes become
spatially separated. Following theoretical proposals, several experiments have
identified signatures of Majorana modes in nanowires with proximity-induced superconductivity
and atomic chains, with small amounts of mode splitting potentially explained
by hybridization of Majorana modes. Here, we use Coulomb-blockade spectroscopy
in an InAs nanowire segment with epitaxial aluminium, which forms a proximity-induced
superconducting Coulomb island (a â ∼ Majorana islandâ (tm)) that is isolated
from normal-metal leads by tunnel barriers, to measure the splitting of near-zero-energy
Majorana modes. We observe exponential suppression of energy splitting with increasing
wire length. For short devices of a few hundred nanometres, sub-gap state energies
oscillate as the magnetic field is varied, as is expected for hybridized Majorana
modes. Splitting decreases by a factor of about ten for each half a micrometre
of increased wire length. For devices longer than about one micrometre, transport
in strong magnetic fields occurs through a zero-energy state that is energetically
isolated from a continuum, yielding uniformly spaced Coulomb-blockade conductance
peaks, consistent with teleportation via Majorana modes. Our results help to explain
the trivial-to-topological transition in finite systems and to quantify the scaling
of topological protection with end-mode separation.

text: 'Recent experiments have produced mounting evidence of Majorana zero modes
in nanowire-superconductor hybrids. Signatures of an expected topological phase
transition accompanying the onset of these modes nevertheless remain elusive.
We investigate a fundamental question concerning this issue: Do well-formed Majorana
modes necessarily entail a sharp phase transition in these setups? Assuming reasonable
parameters, we argue that finite-size effects can dramatically smooth this putative
transition into a crossover, even in systems large enough to support well-localized
Majorana modes. We propose overcoming such finite-size effects by examining the
behavior of low-lying excited states through tunneling spectroscopy. In particular,
the excited-state energies exhibit characteristic field and density dependence,
and scaling with system size, that expose an approaching topological phase transition.
We suggest several experiments for extracting the predicted behavior. As a useful
byproduct, the protocols also allow one to measure the wire''s spin-orbit coupling
directly in its superconducting environment.'

text: Nucleation processes are at the heart of a large number of phenomena, from
cloud formation to protein crystallization. A recently emerging area where nucleation
is highly relevant is the initiation of filamentous protein self-assembly, a process
that has broad implications in many research areas ranging from medicine to nanotechnology.
As such, spontaneous nucleation of protein fibrils has received much attention
in recent years with many theoretical and experimental studies focusing on the
underlying physical principles. In this paper we make a step forward in this direction
and explore the early time behaviour of filamentous protein growth in the context
of nucleation theory. We first provide an overview of the thermodynamics and kinetics
of spontaneous nucleation of protein filaments in the presence of one relevant
degree of freedom, namely the cluster size. In this case, we review how key kinetic
observables, such as the reaction order of spontaneous nucleation, are directly
related to the physical size of the critical nucleus. We then focus on the increasingly
prominent case of filament nucleation that includes a conformational conversion
of the nucleating building-block as an additional slow step in the nucleation
process. Using computer simulations, we study the concentration dependence of
the nucleation rate. We find that, under these circumstances, the reaction order
of spontaneous nucleation with respect to the free monomer does no longer relate
to the overall physical size of the nucleating aggregate but rather to the portion
of the aggregate that actively participates in the conformational conversion.
Our results thus provide a novel interpretation of the common kinetic descriptors
of protein filament formation, including the reaction order of the nucleation
step or the scaling exponent of lag times, and put into perspective current theoretical
descriptions of protein aggregation.

text: The interplay of membrane proteins is vital for many biological processes,
such as cellular transport, cell division, and signal transduction between nerve
cells. Theoretical considerations have led to the idea that the membrane itself
mediates protein self-organization in these processes through minimization of
membrane curvature energy. Here, we present a combined experimental and numerical
study in which we quantify these interactions directly for the first time. In
our experimental model system we control the deformation of a lipid membrane by
adhering colloidal particles. Using confocal microscopy, we establish that these
membrane deformations cause an attractive interaction force leading to reversible
binding. The attraction extends over 2.5 times the particle diameter and has a
strength of three times the thermal energy (−3.3 kBT). Coarse-grained Monte-Carlo
simulations of the system are in excellent agreement with the experimental results
and prove that the measured interaction is independent of length scale. Our combined
experimental and numerical results reveal membrane curvature as a common physical
origin for interactions between any membrane-deforming objects, from nanometre-sized
proteins to micrometre-sized particles.

text: The ability of biological molecules to replicate themselves is the foundation
of life, requiring a complex cellular machinery. However, a range of aberrant
processes involve the self-replication of pathological protein structures without
any additional assistance. One example is the autocatalytic generation of pathological
protein aggregates, including amyloid fibrils, involved in neurodegenerative disorders.
Here, we use computer simulations to identify the necessary requirements for the
self-replication of fibrillar assemblies of proteins. We establish that a key
physical determinant for this process is the affinity of proteins for the surfaces
of fibrils. We find that self-replication can take place only in a very narrow
regime of inter-protein interactions, implying a high level of sensitivity to
system parameters and experimental conditions. We then compare our theoretical
predictions with kinetic and biosensor measurements of fibrils formed from the
Aβ peptide associated with Alzheimer’s disease. Our results show a quantitative
connection between the kinetics of self-replication and the surface coverage of
fibrils by monomeric proteins. These findings reveal the fundamental physical
requirements for the formation of supra-molecular structures able to replicate
themselves, and shed light on mechanisms in play in the proliferation of protein
aggregates in nature.

text: Using non-equilibrium molecular dynamics simulations, it has been recently
demonstrated that water molecules align in response to an imposed temperature
gradient, resulting in an effective electric field. Here, we investigate how thermally
induced fields depend on the underlying treatment of long-ranged interactions.
For the short-ranged Wolf method and Ewald summation, we find the peak strength
of the field to range between 2 × 107 and 5 × 107 V/m for a temperature gradient
of 5.2 K/Å. Our value for the Wolf method is therefore an order of magnitude lower
than the literature value [J. A. Armstrong and F. Bresme, J. Chem. Phys. 139,
014504 (2013); J. Armstrong et al., J. Chem. Phys. 143, 036101 (2015)]. We show
that this discrepancy can be traced back to the use of an incorrect kernel in
the calculation of the electrostatic field. More seriously, we find that the Wolf
method fails to predict correct molecular orientations, resulting in dipole densities
with opposite sign to those computed using Ewald summation. By considering two
different multipole expansions, we show that, for inhomogeneous polarisations,
the quadrupole contribution can be significant and even outweigh the dipole contribution
to the field. Finally, we propose a more accurate way of calculating the electrostatic
potential and the field. In particular, we show that averaging the microscopic
field analytically to obtain the macroscopic Maxwell field reduces the error bars
by up to an order of magnitude. As a consequence, the simulation times required
to reach a given statistical accuracy decrease by up to two orders of magnitude.

text: We study phase behaviour of lipid-bilayer vesicles functionalised by ligand–receptor
complexes made of synthetic DNA by introducing a modelling framework and a dedicated
experimental platform. In particular, we perform Monte Carlo simulations that
combine a coarse grained description of the lipid bilayer with state of art analytical
models for multivalent ligand–receptor interactions. Using density of state calculations,
we derive the partition function in pairs of vesicles and compute the number of
ligand–receptor bonds as a function of temperature. Numerical results are compared
to microscopy and fluorimetry experiments on large unilamellar vesicles decorated
by DNA linkers carrying complementary overhangs. We find that vesicle aggregation
is suppressed when the total number of linkers falls below a threshold value.
Within the model proposed here, this is due to the higher configurational costs
required to form inter-vesicle bridges as compared to intra-vesicle loops, which
are in turn related to membrane deformability. Our findings and our numerical/experimental
methodologies are applicable to the rational design of liposomes used as functional
materials and drug delivery applications, as well as to study inter-membrane interactions
in living systems, such as cell adhesion.

text: 'Games on graphs provide the appropriate framework to study several central
problems in computer science, such as verification and synthesis of reactive systems.
One of the most basic objectives for games on graphs is the liveness (or Büchi)
objective that given a target set of vertices requires that some vertex in the
target set is visited infinitely often. We study generalized Büchi objectives
(i.e., conjunction of liveness objectives), and implications between two generalized
Büchi objectives (known as GR(1) objectives), that arise in numerous applications
in computer-aided verification. We present improved algorithms and conditional
super-linear lower bounds based on widely believed assumptions about the complexity
of (A1) combinatorial Boolean matrix multiplication and (A2) CNF-SAT. We consider
graph games with n vertices, m edges, and generalized Büchi objectives with k
conjunctions. First, we present an algorithm with running time O(k*n^2), improving
the previously known O(k*n*m) and O(k^2*n^2) worst-case bounds. Our algorithm
is optimal for dense graphs under (A1). Second, we show that the basic algorithm
for the problem is optimal for sparse graphs when the target sets have constant
size under (A2). Finally, we consider GR(1) objectives, with k_1 conjunctions
in the antecedent and k_2 conjunctions in the consequent, and present an O(k_1
k_2 n^{2.5})-time algorithm, improving the previously known O(k_1*k_2*n*m)-time

text: "The Continuous Skolem Problem asks whether a real-valued function satisfying
a linear differen-\r\ntial equation has a zero in a given interval of real numbers.
This is a fundamental reachability\r\nproblem for continuous linear dynamical
systems, such as linear hybrid automata and continuous-\r\ntime Markov chains.
Decidability of the problem is currently open – indeed decidability is open\r\neven
for the sub-problem in which a zero is sought in a bounded interval. In this paper
we show\r\ndecidability of the bounded problem subject to Schanuel’s Conjecture,
a unifying conjecture in\r\ntranscendental number theory. We furthermore analyse
the unbounded problem in terms of the\r\nfrequencies of the differential equation,
that is, the imaginary parts of the characteristic roots.\r\nWe show that the
unbounded problem can be reduced to the bounded problem if there is at most\r\none
rationally linearly independent frequency, or if there are two rationally linearly
independent\r\nfrequencies and all characteristic roots are simple. We complete
the picture by showing that de-\r\ncidability of the unbounded problem in the
case of two (or more) rationally linearly independent\r\nfrequencies would entail
a major new effectiveness result in Diophantine approximation, namely\r\ncomputability
of the Diophantine-approximation types of all real algebraic numbers."

text: 'We present a logic that extends CTL (Computation Tree Logic) with operators
that express synchronization properties. A property is synchronized in a system
if it holds in all paths of a certain length. The new logic is obtained by using
the same path quantifiers and temporal operators as in CTL, but allowing a different
order of the quantifiers. This small syntactic variation induces a logic that
can express non-regular properties for which known extensions of MSO with equality
of path length are undecidable. We show that our variant of CTL is decidable and
that the model-checking problem is in Delta_3^P = P^{NP^NP}, and is DP-hard. We
analogously consider quantifier exchange in extensions of CTL, and we present
operators defined using basic operators of CTL* that express the occurrence of
infinitely many synchronization points. We show that the model-checking problem
remains in Delta_3^P. The distinguishing power of CTL and of our new logic coincide
if the Next operator is allowed in the logics, thus the classical bisimulation
quotient can be used for state-space reduction before model checking. '

text: 'We consider data-structures for answering reachability and distance queries
on constant-treewidth graphs with n nodes, on the standard RAM computational model
with wordsize W=Theta(log n). Our first contribution is a data-structure that
after O(n) preprocessing time, allows (1) pair reachability queries in O(1) time;
and (2) single-source reachability queries in O(n/log n) time. This is (asymptotically)
optimal and is faster than DFS/BFS when answering more than a constant number
of single-source queries. The data-structure uses at all times O(n) space. Our
second contribution is a space-time tradeoff data-structure for distance queries.
For any epsilon in [1/2,1], we provide a data-structure with polynomial preprocessing
time that allows pair queries in O(n^{1-\epsilon} alpha(n)) time, where alpha
is the inverse of the Ackermann function, and at all times uses O(n^epsilon) space.
The input graph G is not considered in the space complexity. '

text: Vortex states in superconducting (SC) structures, their dynamics and ways
to manipulate them are topics of great interest. We report a new method of magnetic
force microscopy (MFM) that allows the study of vortex states in mesoscopic SC
samples. For the case of a SC ring, which is biased to a half-integer flux quantum,
the flux modulation through the ring caused by the motion of the magnetic tip
drives the ring between two consecutive fluxoid states. The corresponding current
switching in the ring produces strong position-dependent forces on the cantilever.
In the regime where the frequency of the thermally activated jumps between fluxoid
states is close to the frequency of the cantilever, large changes in the cantilever
frequency and dissipation are observed. This effect may be understood as a stochastic
resonance (SR) process. These changes in the cantilever’s mechanical properties
are used to “image” the barrier energies between fluxoid states. Additionally,
SR imaging of the barrier energies are used to study the effect of the locally
applied magnetic field from the MFM tip on the barrier heights. We report the
results of measurements for Al rings. Further, the same imaging technique can
be applied to more sophisticated SC structures such as arrays of Josephson junctions.

text: Vortex interactions are key to explaining the behavior of many two dimensional
superconducting systems. We report on the development of a technique to locally
probe vortex interactions in a 2D array of Josephson junctions. Scanning a magnetic
tip attached to an ultra-soft cantilever over the array produces changes in the
frequency of the cantilever along certain lines, forming geometric patterns in
the scans. Different tip-surface separations and external magnetic fields produce
a number of different patterns. These patterns correspond to tip locations in
which two configurations of vortices in the lattice have degenerate energies.
By imaging the locations of these degeneracies, information on the local vortex
interactions may be obtained.

text: The asymmetric localization of proteins in the plasma membrane domains of
eukaryotic cells is a fundamental manifestation of cell polarity that is central
to multicellular organization and developmental patterning. In plants, the mechanisms
underlying the polar localization of cargo proteins are still largely unknown
and appear to be fundamentally distinct from those operating in mammals. Here,
we present a systematic, quantitative comparative analysis of the polar delivery
and subcellular localization of proteins that characterize distinct polar plasma
membrane domains in plant cells. The combination of microscopic analyses and computational
modeling revealed a mechanistic framework common to diverse polar cargos and underlying
the establishment and maintenance of apical, basal, and lateral polar domains
in plant cells. This mechanism depends on the polar secretion, constitutive endocytic
recycling, and restricted lateral diffusion of cargos within the plasma membrane.
Moreover, our observations suggest that polar cargo distribution involves the
individual protein potential to form clusters within the plasma membrane and interact
with the extracellular matrix. Our observations provide insights into the shared
cellular mechanisms of polar cargo delivery and polarity maintenance in plant
cells.

text: "The main goal of the SCP-ECG standard is to address ECG data and related
metadata structuring, semantics and syntax, with the objective of facilitating
interoperability and thus supporting and promoting the exchange of the relevant
information for unary and serial ECG diagnosis. Starting with version V3.0, the
standard now also provides support for the storage of continuous, long-term ECG
recordings and affords a repository for selected ECG sequences and the related
metadata to accommodate stress tests, drug trials and protocol-based ECG recordings.
The global and per-lead measurements sections have been extended and three new
sections have been introduced for storing beat-by-beat and/or spike-by-spike measurements\r\nand
annotations. The used terminology and the provided measurements and annotations
have been harmonized with the ISO/IEEE 11073-10102 Annotated ECG standard. Emphasis
has also been put on harmonizing the Universal Statement Codes with the CDISC
and the categorized AHA statement codes and similarly the drug and implanted devices
codes with the ATC and NASPE/BPEG codes. "

text: The discovery of introns four decades ago was one of the most unexpected findings
in molecular biology. Introns are sequences interrupting genes that must be removed
as part of messenger RNA production. Genome sequencing projects have shown that
most eukaryotic genes contain at least one intron, and frequently many. Comparison
of these genomes reveals a history of long evolutionary periods during which few
introns were gained, punctuated by episodes of rapid, extensive gain. However,
although several detailed mechanisms for such episodic intron generation have
been proposed, none has been empirically supported on a genomic scale. Here we
show how short, non-autonomous DNA transposons independently generated hundreds
to thousands of introns in the prasinophyte Micromonas pusilla and the pelagophyte
Aureococcus anophagefferens. Each transposon carries one splice site. The other
splice site is co-opted from the gene sequence that is duplicated upon transposon
insertion, allowing perfect splicing out of the RNA. The distributions of sequences
that can be co-opted are biased with respect to codons, and phasing of transposon-generated
introns is similarly biased. These transposons insert between pre-existing nucleosomes,
so that multiple nearby insertions generate nucleosome-sized intervening segments.
Thus, transposon insertion and sequence co-option may explain the intron phase
biases and prevalence of nucleosome-sized exons observed in eukaryotes. Overall,
the two independent examples of proliferating elements illustrate a general DNA
transposon mechanism that can plausibly account for episodes of rapid, extensive
intron gain during eukaryotic evolution.

text: Cytosine DNA methylation regulates the expression of eukaryotic genes and
transposons. Methylation is copied by methyltransferases after DNA replication,
which results in faithful transmission of methylation patterns during cell division
and, at least in flowering plants, across generations. Transgenerational inheritance
is mediated by a small group of cells that includes gametes and their progenitors.
However, methylation is usually analyzed in somatic tissues that do not contribute
to the next generation, and the mechanisms of transgenerational inheritance are
inferred from such studies. To gain a better understanding of how DNA methylation
is inherited, we analyzed purified Arabidopsis thaliana sperm and vegetative cells-the
cell types that comprise pollen-with mutations in the DRM, CMT2, and CMT3 methyltransferases.
We find that DNA methylation dependency on these enzymes is similar in sperm,
vegetative cells, and somatic tissues, although DRM activity extends into heterochromatin
in vegetative cells, likely reflecting transcription of heterochromatic transposons
in this cell type. We also show that lack of histone H1, which elevates heterochromatic
DNA methylation in somatic tissues, does not have this effect in pollen. Instead,
levels of CG methylation in wild-type sperm and vegetative cells, as well as in
wild-type microspores from which both pollen cell types originate, are substantially
higher than in wild-type somatic tissues and similar to those of H1-depleted roots.
Our results demonstrate that the mechanisms of methylation maintenance are similar
between pollen and somatic cells, but the efficiency of CG methylation is higher
in pollen, allowing methylation patterns to be accurately inherited across generations.

text: Cytosine methylation is a DNA modification with important regulatory functions
in eukaryotes. In flowering plants, sexual reproduction is accompanied by extensive
DNA demethylation, which is required for proper gene expression in the endosperm,
a nutritive extraembryonic seed tissue. Endosperm arises from a fusion of a sperm
cell carried in the pollen and a female central cell. Endosperm DNA demethylation
is observed specifically on the chromosomes inherited from the central cell in
Arabidopsis thaliana, rice, and maize, and requires the DEMETER DNA demethylase
in Arabidopsis. DEMETER is expressed in the central cell before fertilization,
suggesting that endosperm demethylation patterns are inherited from the central
cell. Down-regulation of the MET1 DNA methyltransferase has also been proposed
to contribute to central cell demethylation. However, with the exception of three
maize genes, central cell DNA methylation has not been directly measured, leaving
the origin and mechanism of endosperm demethylation uncertain. Here, we report
genome-wide analysis of DNA methylation in the central cells of Arabidopsis and
rice—species that diverged 150 million years ago—as well as in rice egg cells.
We find that DNA demethylation in both species is initiated in central cells,
which requires DEMETER in Arabidopsis. However, we do not observe a global reduction
of CG methylation that would be indicative of lowered MET1 activity; on the contrary,
CG methylation efficiency is elevated in female gametes compared with nonsexual
tissues. Our results demonstrate that locus-specific, active DNA demethylation
in the central cell is the origin of maternal chromosome hypomethylation in the
endosperm.
