text: Arabidopsis thaliana endosperm, a transient tissue that nourishes the embryo,
exhibits extensive localized DNA demethylation on maternally inherited chromosomes.
Demethylation mediates parent-of-origin–specific (imprinted) gene expression but
is apparently unnecessary for the extensive accumulation of maternally biased
small RNA (sRNA) molecules detected in seeds. Endosperm DNA in the distantly related
monocots rice and maize is likewise locally hypomethylated, but whether this hypomethylation
is generally parent-of-origin specific is unknown. Imprinted expression of sRNA
also remains uninvestigated in monocot seeds. Here, we report high-coverage sequencing
of the Kitaake rice cultivar that enabled us to show that localized hypomethylation
in rice endosperm occurs solely on the maternal genome, preferring regions of
high DNA accessibility. Maternally expressed imprinted genes are enriched for
hypomethylation at putative promoter regions and transcriptional termini and paternally
expressed genes at promoters and gene bodies, mirroring our recent results in
A. thaliana. However, unlike in A. thaliana, rice endosperm sRNA populations are
dominated by specific strong sRNA-producing loci, and imprinted 24-nt sRNAs are
expressed from both parental genomes and correlate with hypomethylation. Overlaps
between imprinted sRNA loci and imprinted genes expressed from opposite alleles
suggest that sRNAs may regulate genomic imprinting. Whereas sRNAs in seedling
tissues primarily originate from small class II (cut-and-paste) transposable elements,
those in endosperm are more uniformly derived, including sequences from other
transposon classes, as well as genic and intergenic regions. Our data indicate
that the endosperm exhibits a unique pattern of sRNA expression and suggest that
localized hypomethylation of maternal endosperm DNA is conserved in flowering
plants.

text: Plants undergo alternation of generation in which reproductive cells develop
in the plant body ("sporophytic generation") and then differentiate into a multicellular
gamete-forming "gametophytic generation." Different populations of helper cells
assist in this transgenerational journey, with somatic tissues supporting early
development and single nurse cells supporting gametogenesis. New data reveal a
two-way relationship between early reproductive cells and their helpers involving
complex epigenetic and signaling networks determining cell number and fate. Later,
the egg cell plays a central role in specifying accessory cells, whereas in both
gametophytes, companion cells contribute non-cell-autonomously to the epigenetic
landscape of the gamete genomes.

text: 'Molecular dynamics simulations of small Cu nanoparticles using three different
interatomic potentials at rising temperature indicate that small nanoparticles
can undergo solid-solid structural transitions through a direct geometrical conversion
route. The direct geometrical conversion can happen for cuboctahedral nanoparticles,
which turn into an icosahedra shape: one diagonal of the square faces contracts,
and the faces are folded along the diagonal to give rise to two equilateral triangles.
The transition is a kinetic process that cannot be fully explained through an
energetic point of view. It has low activation energy and fast reaction time in
the simulations. The transition mechanism is via the transmission of shear waves
initiated from the particle surface and does not involve dislocation activity.'

text: The coalescence of nano-crystals during sintering is often found to result
in interesting crystalline structures such as multi-fold twins, and yet the plasticity
mechanism accompanying their formation is unclear. In this work, the sintering
behavior of two unsupported copper nanoparticles initially at room temperature
is investigated by molecular dynamics simulations under the constant-energy ensemble.
The results reveal that once the two nanoparticles are brought into contact, they
often go through drastic structural changes with the inter-particle grain boundary
quickly eliminated, and single- and multi-fold twinning occurs frequently in the
coalesced product. Whereas the formation of single twins is found to be via the
more usual mechanism of emission of Shockley partials on {1 1 1} planes, the formation
of fivefold twins, however, takes place via a novel dislocation-free mechanism
involving a series of shear and rigid-body rotation processes caused by elastic
waves with amplitudes not corresponding to any allowable Burgers vector in the
fcc lattice. Such a lattice-wave, dislocation-free twinning mechanism has never
been reported before.

text: Despite its relevance to a range of technological applications including nanocrystalline
material fabrication, the sintering mechanisms of nanoparticles have not been
well understood. It has been recognized that extrapolation from understanding
of macro-particle sintering is unreliable for the nano-particle size regime. In
this work, the sintering behaviour of copper nanoparticles under periodic boundary
conditions at different temperatures and pressures was investigated by Molecular
Dynamics simulations. It was found that smaller particle sizes, higher temperature
and higher external pressure facilitate densification. Through a comparison with
a two-sphere model, the governing mechanisms for many nanoparticles sintered at
low temperature (T⩽900K) were identified to be a variety of plasticity processes
including dislocation, twinning and even amorphization at the contact neck regions,
due to the presence of high stresses.

text: In this work, we simulate the response of two Cu nanoparticles colliding at
different approaching rates at room temperature by MD. For small nanospheres,
the formation of single twins is favored at high approach rates, whereas larger
nanospheres mainly deform by dislocation slip. For small nanocubes with large
{100} flat surfaces, however, a dislocation-free direct geometrical conversion
process that leads to five-fold twinning dominates except at highly retarded approaching
rates. For larger nanocubes, single twin formation is the governing plasticity
mechanism. The probability for plastic deformation by dislocation slip or twinning
is attributed to the abundance of surface steps, which act as sites for dislocation
nucleation.

in three dimensions. We study two systems: self-propelled particles interacting
via a generic attractive potential and colloids that can move toward each other
as a result of active agents (e.g., by molecular motors). In both cases, fluidlike
“living” clusters form. We explain this general feature in terms of the balance
between active forces and regression to thermodynamic equilibrium. This balance
can be quantified in terms of a dimensionless number that allows us to collapse
the observed clustering behavior onto a universal curve. We also discuss how active
motion affects the kinetics of crystal formation.'

text: We show how self-assembly of sticky nanoparticles can drive radial collapse
of thin-walled nanotubes. Using numerical simulations, we study the transition
as a function of the geometric and elastic parameters of the nanotube and the
binding strength of the nanoparticles. We find that it is possible to derive a
simple scaling law relating all these parameters, and estimate bounds for the
onset conditions leading to the collapse of the nanotube. We also study the reverse
process – the nanoparticle release from the folded state – and find that the stability
of the collapsed state can be greatly improved by increasing the bending rigidity
of the nanotubes. Our results suggest ways to strengthen the mechanical properties
of nanotubes, but also indicate that the control of nanoparticle self-assembly
on these nanotubes can lead to nanoparticle-laden responsive materials.

text: In this paper we review recent numerical and theoretical developments of particle
self-assembly on fluid and elastic membranes and compare them to available experimental
realizations. We discuss the problem and its applications in biology and materials
science, and give an overview of numerical models and strategies to study these
systems across all length-scales. As this is a very broad field, this review focuses
exclusively on surface-driven aggregation of nanoparticles that are at least one
order of magnitude larger than the surface thickness and are adsorbed onto it.
In this regime, all chemical details of the surface can be ignored in favor of
a coarse-grained representation, and the collective behavior of many particles
can be monitored and analyzed. We review the existing literature on how the mechanical
properties and the geometry of the surface affect the structure of the particle
aggregates and how these can drive shape deformation on the surface.

text: 'We study dynamic (1 + ϵ)-approximation algorithms for the all-pairs shortest
paths problem in unweighted undirected n-node m-edge graphs under edge deletions.
The fastest algorithm for this problem is a randomized algorithm with a total
update time of Ȏ(mn) and constant query time by Roditty and Zwick (FOCS 2004).
The fastest deterministic algorithm is from a 1981 paper by Even and Shiloach
(JACM 1981); it has a total update time of O(mn 2 ) and constant query time. We
improve these results as follows: (1) We present an algorithm with a total update
time of Ȏ(n 5/2 ) and constant query time that has an additive error of two in
addition to the 1 + ϵ multiplicative error. This beats the previous Ȏ(mn) time
when m = Ω(n 3/2 ). Note that the additive error is unavoidable since, even in
the static case, an O(n 3-δ )-time (a so-called truly sub cubic) combinatorial
algorithm with 1 + ϵ multiplicative error cannot have an additive error less than
2 - ϵ, unless we make a major breakthrough for Boolean matrix multiplication (Dor,
Halperin and Zwick FOCS 1996) and many other long-standing problems (Vassilevska
Williams and Williams FOCS 2010). The algorithm can also be turned into a (2 +
ϵ)-approximation algorithm (without an additive error) with the same time guarantees,
improving the recent (3 + ϵ)-approximation algorithm with Ȏ(n 5/2+O(1√(log n))
) running time of Bernstein and Roditty (SODA 2011) in terms of both approximation
and time guarantees. (2) We present a deterministic algorithm with a total update
time of Ȏ(mn) and a query time of O(log log n). The algorithm has a multiplicative
error of 1 + ϵ and gives the first improved deterministic algorithm since 1981.
It also answers an open question raised by Bernstein in his STOC 2013 paper. In
order to achieve our results, we introduce two new techniques: (1) A lazy Even-Shiloach
tree algorithm which maintains a bounded-distance shortest-paths tree on a certain
type of emulator called locally persevering emulator. (2) A derandomization technique
based on moving Even-Shiloach trees as a way to derandomize the standard random
set argument. These techniques might be of independent interest.'

text: "We study the problem of matching bidders to items where each bidder i has
general, strictly monotonic utility functions ui,j(pj) expressing his utility
of being matched to item j at price pj. For this setting we prove that a bidder
optimal outcome always exists, even when the utility functions are non-linear
and non-continuous. We give sufficient conditions under\r\nwhich every mechanism
that finds a bidder optimal outcome is incentive compatible. We also give a mechanism
that finds a bidder optimal outcome if the conditions for incentive compatibility
are satisfied. The running time of this mechanism is exponential in the number
of items, but polynomial in the number of bidders."

text: No catalyst required! A highly efficient, catalyst-free process to generate
diimide in situ from hydrazine monohydrate and molecular oxygen for the selective
reduction of alkenes has been developed. The use of a gas–liquid segmented flow
system allowed safe operating conditions and dramatically enhanced this atom-economical
reaction, resulting in short processing times.

text: We use two hydrological models of varying complexity to study the Juncal River
Basin in the Central Andes of Chile with the aim to understand the degree of conceptualization
and the spatial structure that are needed to model present and future streamflows.
We use a conceptual semi-distributed model based on elevation bands [Water Evaluation
and Planning (WEAP)], frequently used for water management, and a physically oriented,
fully distributed model [Topographic Kinematic Wave Approximation and Integration
ETH Zurich (TOPKAPI-ETH)] developed for research purposes mainly. We evaluate
the ability of the two models to reproduce the key hydrological processes in the
basin with emphasis on snow accumulation and melt, streamflow and the relationships
between internal processes. Both models are capable of reproducing observed runoff
and the evolution of Moderate-resolution Imaging Spectroradiometer snow cover
adequately. In spite of WEAP's simple and conceptual approach for modelling snowmelt
and its lack of glacier representation and snow gravitational redistribution as
well as a proper routing algorithm, this model can reproduce historical data with
a similar goodness of fit as the more complex TOPKAPI-ETH. We show that the performance
of both models can be improved by using measured precipitation gradients of higher
temporal resolution. In contrast to the good performance of the conceptual model
for the present climate, however, we demonstrate that the simplifications in WEAP
lead to error compensation, which results in different predictions in simulated
melt and runoff for a potentially warmer future climate. TOPKAPI-ETH, using a
more physical representation of processes, depends less on calibration and thus
is less subject to a compensation of errors through different model components.
Our results show that data obtained locally in ad hoc short-term field campaigns
are needed to complement data extrapolated from long-term records for simulating
changes in the water cycle of high-elevation catchments but that these data can
only be efficiently used by a model applying a spatially distributed physical
representation of hydrological processes.

text: Central Asian water resources largely depend on melt water generated in the
Pamir and Tien Shan mountain ranges. To estimate future water availability in
this region, it is necessary to use climate projections to estimate the future
glacier extent and volume. In this study, we evaluate the impact of uncertainty
in climate change projections on the future glacier extent in the Amu and Syr
Darya river basins. To this end we use the latest climate change projections generated
for the upcoming IPCC report (CMIP5) and, for comparison, projections used in
the fourth IPCC assessment (CMIP3). With these projections we force a regionalized
glacier mass balance model, and estimate changes in the basins' glacier extent
as a function of the glacier size distribution in the basins and projected temperature
and precipitation. This glacier mass balance model is specifically developed for
implementation in large scale hydrological models, where the spatial resolution
does not allow for simulating individual glaciers and data scarcity is an issue.
Although the CMIP5 ensemble results in greater regional warming than the CMIP3
ensemble and the range in projections for temperature as well as precipitation
is wider for the CMIP5 than for the CMIP3, the spread in projections of future
glacier extent in Central Asia is similar for both ensembles. This is because
differences in temperature rise are small during periods of maximum melt (July–September)
while differences in precipitation change are small during the period of maximum
accumulation (October–February). However, the model uncertainty due to parameter
uncertainty is high, and has roughly the same importance as uncertainty in the
climate projections. Uncertainty about the size of the decline in glacier extent
remains large, making estimates of future Central Asian glacier evolution and
downstream water availability uncertain.

text: 'In the headwater catchments of the main Asian rivers, glaciohydrological
models are a useful tool to anticipate impacts of climatic changes. However, the
reliability of their projections strongly depends on the quality and quantity
of data that are available for parameter estimation, model calibration and validation,
as well as on the accuracy of climate change projections. In this study the physically
oriented, glaciohydrological model TOPKAPI-ETH is used to simulate future changes
in snow, glacier, and runoff from the Hunza River Basin in northern Pakistan.
Three key sources of model uncertainty in future runoff projections are compared:
model parameters, climate projections, and natural climate variability. A novel
approach, applicable also to ungauged catchments, is used to determine which model
parameters and model components significantly affect the overall model uncertainty.
We show that the model is capable of reproducing streamflow and glacier mass balances,
but that all analyzed sources of uncertainty significantly affect the reliability
of future projections, and that their effect is variable in time and in space.
The effect of parametric uncertainty often exceeds the impact of climate uncertainty
and natural climate variability, especially in heavily glacierized subcatchments.
The results of the uncertainty analysis allow detailed recommendations on network
design and the timing and location of field measurements, which could efficiently
help to reduce model uncertainty in the future.'

text: Greater Himalayan glaciers are retreating and losing mass at rates comparable
to glaciers in other regions of the world1,2,3,4,5. Assessments of future changes
and their associated hydrological impacts are scarce, oversimplify glacier dynamics
or include a limited number of climate models6,7,8,9. Here, we use results from
the latest ensemble of climate models in combination with a high-resolution glacio-hydrological
model to assess the hydrological impact of climate change on two climatically
contrasting watersheds in the Greater Himalaya, the Baltoro and Langtang watersheds
that drain into the Indus and Ganges rivers, respectively. We show that the largest
uncertainty in future runoff is a result of variations in projected precipitation
between climate models. In both watersheds, strong, but highly variable, increases
in future runoff are projected and, despite the different characteristics of the
watersheds, their responses are surprisingly similar. In both cases, glaciers
will recede but net glacier melt runoff is on a rising limb at least until 2050.
In combination with a positive change in precipitation, water availability during
this century is not likely to decline. We conclude that river basins that depend
on monsoon rains and glacier melt will continue to sustain the increasing water
demands expected in these areas10.

text: We investigate the sensitivity of a distributed enhanced temperature-index
(ETI) melt model, in order to understand which parameters have the largest influence
on model outputs and thus need to be accurately known. We use melt and meteorological
data from two Alpine glaciers and one glacier in the Andes of Chile. Sensitivity
analysis is conducted in a systematic way in terms of parameters and the different
conditions (day, night, clear-sky, overcast), melt seasons and glaciers examined.
The sensitivity of total melt to changes in individual parameters is calculated
using a local method around the optimal value of the parameters. We verify that
the parameters are optimal at the distributed scale and assess the model uncertainty
induced by uncertainty in the parameters using a Monte Carlo technique. Model
sensitivity to parameters is consistent across melt seasons, glaciers, different
conditions and the daily statistics examined. The parameters to which the model
is most sensitive are the shortwave-radiation factor, the temperature lapse rate
for extrapolation of air temperature, the albedo parameters, the temperature threshold
and the cloud transmittance factor parameters. A parameter uncertainty of 5% results
in a model uncertainty of 5.6% of mean melt on Haut Glacier d’Arolla, Switzerland.
