text: Given a symmetric variety Y defined over Q and a non-zero polynomial with
integer coefficients, we use techniques from homogeneous dynamics to establish
conditions under which the polynomial can be made r-free for a Zariski dense set
of integral points on Y . We also establish an asymptotic counting formula for
this set. In the special case that Y is a quadric hypersurface, we give explicit
bounds on the size of r by combining the argument with a uniform upper bound for
the density of integral points on general affine quadrics defined over Q.

text: Given a number field K/Q and a polynomial P ε Q [t], all of whose roots are
Q, let X be the variety defined by the equation NK (x) = P (t). Combining additive
combinatiorics with descent we show that the Brauer-Manin obstruction is the only
obstruction to the Hesse principle and weak approximation on any smooth and projective

text: We consider the problem of estimating the partition function Z(β)=∑xexp(−β(H(x))
of a Gibbs distribution with a Hamilton H(⋅), or more precisely the logarithm
of the ratio q=lnZ(0)/Z(β). It has been recently shown how to approximate q with
high probability assuming the existence of an oracle that produces samples from
the Gibbs distribution for a given parameter value in [0,β]. The current best
known approach due to Huber [9] uses O(qlnn⋅[lnq+lnlnn+ε−2]) oracle calls on average
where ε is the desired accuracy of approximation and H(⋅) is assumed to lie in
{0}∪[1,n]. We improve the complexity to O(qlnn⋅ε−2) oracle calls. We also show
that the same complexity can be achieved if exact oracles are replaced with approximate
sampling oracles that are within O(ε2qlnn) variation distance from exact oracles.
Finally, we prove a lower bound of Ω(q⋅ε−2) oracle calls under a natural model
of computation.

text: DNA methylation regulates eukaryotic gene expression and is extensively reprogrammed
during animal development. However, whether developmental methylation reprogramming
during the sporophytic life cycle of flowering plants regulates genes is presently
unknown. Here we report a distinctive gene-targeted RNA-directed DNA methylation
(RdDM) activity in the Arabidopsis thaliana male sexual lineage that regulates
gene expression in meiocytes. Loss of sexual-lineage-specific RdDM causes mis-splicing
of the MPS1 gene (also known as PRD2), thereby disrupting meiosis. Our results
establish a regulatory paradigm in which de novo methylation creates a cell-lineage-specific
epigenetic signature that controls gene expression and contributes to cellular
function in flowering plants.

text: Since 2006, reprogrammed cells have increasingly been used as a biomedical
research technique in addition to neuro-psychiatric methods. These rapidly evolving
techniques allow for the generation of neuronal sub-populations, and have sparked
interest not only in monogenetic neuro-psychiatric diseases, but also in poly-genetic
and poly-aetiological disorders such as schizophrenia (SCZ) and bipolar disorder
(BPD). This review provides a summary of 19 publications on reprogrammed adult
somatic cells derived from patients with SCZ, and five publications using this
technique in patients with BPD. As both disorders are complex and heterogeneous,
there is a plurality of hypotheses to be tested in vitro. In SCZ, data on alterations
of dopaminergic transmission in vitro are sparse, despite the great explanatory
power of the so-called DA hypothesis of SCZ. Some findings correspond to perturbations
of cell energy metabolism, and observations in reprogrammed cells suggest neuro-developmental
alterations. Some studies also report on the efficacy of medicinal compounds to
revert alterations observed in cellular models. However, due to the paucity of
replication studies, no comprehensive conclusions can be drawn from studies using
reprogrammed cells at the present time. In the future, findings from cell culture
methods need to be integrated with clinical, epidemiological, pharmacological
and imaging data in order to generate a more comprehensive picture of SCZ and
BPD.

text: The Leidenfrost effect occurs when an object near a hot surface vaporizes
rapidly enough to lift itself up and hover. Although well understood for liquids
and stiff sublimable solids, nothing is known about the effect with materials
whose stiffness lies between these extremes. Here we introduce a new phenomenon
that occurs with vaporizable soft solids - the elastic Leidenfrost effect. By
dropping hydrogel spheres onto hot surfaces we find that, rather than hovering,
they energetically bounce several times their diameter for minutes at a time.
With high-speed video during a single impact, we uncover high-frequency microscopic
gap dynamics at the sphere/substrate interface. We show how these otherwise-hidden
agitations constitute work cycles that harvest mechanical energy from the vapour
and sustain the bouncing. Our findings suggest a new strategy for injecting mechanical
energy into a widely used class of soft materials, with potential relevance to
fields such as active matter, soft robotics and microfluidics.

text: We consider the problems of maintaining approximate maximum matching and minimum
vertex cover in a dynamic graph. Starting with the seminal work of Onak and Rubinfeld
[STOC 2010], this problem has received significant attention in recent years.
Very recently, extending the framework of Baswana, Gupta and Sen [FOCS 2011],
Solomon [FOCS 2016] gave a randomized 2-approximation dynamic algorithm for this
problem that has amortized update time of O(1) with high probability. We consider
the natural open question of derandomizing this result. We present a new deterministic
fully dynamic algorithm that maintains a O(1)-approximate minimum vertex cover
and maximum fractional matching, with an amortized update time of O(1). Previously,
the best deterministic algorithm for this problem was due to Bhattacharya, Henzinger
and Italiano [SODA 2015]; it had an approximation ratio of (2+ϵ) and an amortized
update time of O(logn/ϵ2). Our result can be generalized to give a fully dynamic
O(f3)-approximation algorithm with O(f2) amortized update time for the hypergraph
vertex cover and fractional matching problems, where every hyperedge has at most
f vertices.

text: The spatio-temporal distribution of air temperature over mountain glaciers
can demonstrate complex patterns, yet it is often represented simplistically using
linear vertical temperature gradients (VTGs) extrapolated from off-glacier locations.
We analyse a network of centreline and lateral air temperature observations at
Tsanteleina Glacier, Italy, during summer 2015. On average, VTGs are steep (<−0.0065
°C m−1), but they are shallow under warm ambient conditions
when the correlation between air temperature and elevation becomes weaker. Published
along-flowline temperature distribution methods explain centreline observations
well, including warming on the lower glacier tongue, but cannot estimate lateral
temperature variability. Application of temperature distribution methods improves
simulation of melt rates (RMSE) in an energy-balance model by up to 36% compared
to the environmental lapse rate extrapolated from an off-glacier station. However,
results suggest that model parameters are not easily transferable to glaciers
with a small fetch without recalibration. Such methods have potential to improve
estimates of temperature across a glacier, but their parameter transferability
should be further linked to the glacier and atmospheric characteristics. Furthermore,
‘cold spots’, which can be >2°C cooler than expected for their elevation, whose
occurrence is not predicted by the temperature distribution models, are identified
at one-quarter of the measurement sites.

text: Previous estimates of melt and surface sublimation on glaciers of the subtropical
semiarid Andes (29–34°S) have been obtained at few specific locations, but it
is not clear how ablation components vary across the entire extent of a glacier
in this dry environment. Here, we simulate the distributed energy and mass balance
of Juncal Norte Glacier (33°S) during a 2-month summer period. Forcing fields
of near-surface air temperature and wind speed are generated using two methods
accounting for the main physical processes that shape their spatial variations.
Simulated meteorological variables and ablation agree well with observations on
the glacier tongue and reveal complex patterns of energy and mass fluxes. Ablation
decreases from 70 mm w.e. d−1 at the low-albedo glacier terminus
(~3000 m), where almost 100% of total ablation corresponds to melt, to <5 mm
w.e. d−1 at wind-exposed, strong-radiated sites above 5500
m, where surface sublimation represents >75% of total ablation. Our simulations
provide the first glacier-scale estimates of ablation components on a glacier
in the study region and better reproduce the observed and expected spatial variations
of melt and surface sublimation, in comparison with more simple assumptions, such
as linear gradients and uniform wind speeds.

text: The hydrological systems of heavily-downwasted debris-covered glaciers differ
from those of clean-ice glaciers due to the hummocky surface and debris mantle
of such glaciers, leading to a relatively limited understanding of drainage pathways.
Supraglacial ponds represent sinks within the discontinuous supraglacial drainage
system, and occasionally drain englacially. To assess pond dynamics, we made pond
water level measurements on Lirung Glacier, Nepal, during May and October of 2013
and 2014. Simultaneously, aerial, satellite, and terrestrial orthoimages and digital
elevation models were obtained, providing snapshots of the ponds and their surroundings.
We performed a DEM-based analysis of the glacier's closed surface catchments to
identify surface drainage pathways and englacial drainage points, and compared
this to field observations of surface and near-surface water flow. The total ponded
area was higher in the pre-monsoon than post-monsoon, with individual ponds filling
and draining seasonally associated with the surface exposure of englacial conduit
segments. We recorded four pond drainage events, all of which occurred gradually
(duration of weeks), observed diurnal fluctuations indicative of varying water
supply and outflow discharge, and we documented instances of interaction between
distant ponds. The DEM drainage analysis identified numerous sinks >3 m in depth
across the glacier surface, few of which exhibited ponds (23%), while the field
survey highlighted instances of surface water only explicable via englacial routes.
Taken together, our observations provide evidence for widespread supraglacial-englacial
connectivity of meltwater drainage paths. Results suggest that successive englacial
conduit collapse events, themselves likely driven by supraglacial pond drainage,
cause the glacier surface drainage system to evolve into a configuration following
relict englacial conduit systems. Within this system, ponds form in depressions
of reduced drainage efficiency and link the supraglacial and englacial drainage
networks.

text: 'We investigate the energy balance and ablation regimes of glaciers in high-elevation,
dry environments using glaciometeorological data collected on six glaciers in
the semiarid Andes of North-Central Chile (29–34°S, 3127–5324 m). We use a point-scale
physically based energy balance (EB) model and an enhanced Temperature-Index (ETI)
model that calculates melt rates only as a function of air temperature and net
shortwave radiation. At all sites, the largest energy inputs are net shortwave
and incoming longwave radiation, which are controlled by surface albedo and elevation,
respectively. Turbulent fluxes cancel each other out at the lower sites, but as
elevation increases, cold, dry and wind-exposed conditions increase the magnitude
of negative latent heat fluxes, associated with large surface sublimation rates.
In midsummer (January), ablation rates vary from 67.9 mm w.e. d−1 at the lowest
site (∼100% corresponding to melt), to 2.3 mm w.e. d−1 at the highest site (>85%
corresponding to surface sublimation). At low-elevation, low-albedo, melt-dominated
sites, the ETI model correctly reproduces melt using a large range of possible
parameters, but both the performance and parameter transferability decrease with
elevation for two main reasons: (i) the air temperature threshold approach for
melt onset does not capture the diurnal variability of melt in cold and strong
irradiated environments and (ii) energy losses decrease the correlation between
melt and net shortwave radiation. We summarize our results by means of an elevation
profile of ablation components that can be used as reference in future studies
of glacier ablation in the semiarid Andes.'

text: Supraglacial ponds play a key role in absorbing atmospheric energy and directing
it to the ice of debris-covered glaciers, but the spatial and temporal distribution
of these features is not well documented. We analyse 172 Landsat TM/ETM+ scenes
for the period 1999–2013 to identify thawed supraglacial ponds for the debris-covered
tongues of five glaciers in the Langtang Valley of Nepal. We apply an advanced
atmospheric correction routine (Landcor/6S) and use band ratio and image morphological
techniques to identify ponds and validate our results with 2.5 m Cartosat-1 observations.
We then characterize the spatial, seasonal and interannual patterns of ponds.
We find high variability in pond incidence between glaciers (May–October means
of 0.08–1.69% of debris area), with ponds most frequent in zones of low surface
gradient and velocity. The ponds show pronounced seasonality, appearing in the
pre-monsoon as snow melts, peaking at the monsoon onset at 2% of debris-covered
area, then declining in the post-monsoon as ponds drain or freeze. Ponds are highly
recurrent and persistent, with 40.5% of pond locations occurring for multiple
years. Rather than a trend in pond cover over the study period, we find high interannual
variability for each glacier after controlling for seasonality.

text: We study controller synthesis problems for finite-state Markov decision processes,
where the objective is to optimize the expected mean-payoff performance and stability
(also known as variability in the literature). We argue that the basic notion
of expressing the stability using the statistical variance of the mean payoff
is sometimes insufficient, and propose an alternative definition. We show that
a strategy ensuring both the expected mean payoff and the variance below given
bounds requires randomization and memory, under both the above definitions. We
then show that the problem of finding such a strategy can be expressed as a set
of constraints.

text: "Transforming deterministic ω\r\n-automata into deterministic parity automata
is traditionally done using variants of appearance records. We present a more
efficient variant of this approach, tailored to Rabin automata, and several optimizations
applicable to all appearance records. We compare the methods experimentally and
find out that our method produces smaller automata than previous approaches. Moreover,
the experiments demonstrate the potential of our method for LTL synthesis, using
LTL-to-Rabin translators. It leads to significantly smaller parity automata when
compared to state-of-the-art approaches on complex formulae."

text: The growth of crystals of aromatic compounds from water much depends on the
nature of the water solubilizing functions that they carry. Rationalizing crystallization
from water, and structure elucidation, of aromatic molecular and supramolecular
systems is of general value across various fields of chemistry. Taking helical
aromatic foldamers as a test case, we have validated several short polar side
chains as efficient substituents to provide both solubility in, and crystal growth
ability from, water. New 8-amino-2-quinolinecarboxylic acids bearing charged or
neutral aminomethyl, carboxymethyl, sulfonic acid, or bis(hydroxymethyl)-methoxy
side chains in position 4 or 5, were prepared on a multi gram scale. Fmoc protection
of the main chain amine and suitable protections of the side chains ensured compatibility
with solid phase synthesis. One tetrameric and five octameric oligoamides displaying
these side chains were synthesized and shown to be soluble in water. In all cases
but one, crystals were obtained using the hanging drop method, thus validating
the initial design principle to combine polarity and rigidity. The only case that
resisted crystallization appeared to be due to exceedingly high water solubility
endowed by eight sulfonic acid functions. The neutral side chain did provide crystal
growth ability from water but contributed poorly to solubility.

text: The crystal structure of the tetradecanucleotide d(CCCCGGTACCGGGG)2 has previously
been reported as an A-type double helix at a resolution of 2.5 Å in space group
P41. Here, the structure of this sequence was determined at a significantly higher
resolution of 1.65 Å in space group P41212. The differences in crystal packing
between the former and latter are described. The crystallographic asymmetric unit
consists of one tetradecanucleotide duplex that spans more than one full turn
of the A-helix. This structure allowed the unambiguous identification of solvent
interactions.

text: We present here a comparison of three different X-ray crystal structures of
DNA tetradecamer sequence d(CCCGGGTACCCGGG)2 all at about 1.7 Å resolution. The
sequence was designed as an attempt to form a DNA four-way junction with A-type
helical arms. However, in the presence of zinc, magnesium, and in the absence
of any metal ion, it does not take up the junction structure, but forms an A-type
double helix. This allowed us to study possible conformational changes in the
double helix due to the presence of metal ions. Upon addition of the zinc ion,
there is a change in the space group from P41212 to P41. The overall conformation
of the duplex remains the same. There are small changes in the interaction of
the metal ions with the DNA. In the zinc-bound structure, there are two zinc ions
that show direct interaction with the N7 atoms of terminal G13 bases at either
end of the molecule. There are small changes in the interhelical contacts. The
consequence of these differences is to break some of the symmetry and change the
space group.

text: The Smith-Purcell effect, observed when an electron beam passes in the vicinity
of a periodic structure, is a promising platform for the generation of electromagnetic
radiation in previously unreachable spectral ranges. However, most of the studies
of this radiation were performed on simple periodic gratings, whose radiation
spectrum exhibits a single peak and its higher harmonics predicted by a well-established
dispersion relation. Here, we propose a method to shape the spatial and spectral
far-field distribution of the radiation using complex periodic and aperiodic gratings.
We show, theoretically and experimentally, that engineering multiple peak spectra
with controlled widths located at desired wavelengths is achievable using Smith-Purcell
radiation. Our method opens the way to free-electron-driven sources with tailored
angular and spectral responses, and gives rise to focusing functionality for spectral
ranges where lenses are unavailable or inefficient.
