text: Systems such as fluid flows in channels and pipes or the complex Ginzburg–Landau
system, defined over periodic domains, exhibit both continuous symmetries, translational
and rotational, as well as discrete symmetries under spatial reflections or complex
conjugation. The simplest, and very common symmetry of this type is the equivariance
of the defining equations under the orthogonal group O(2). We formulate a novel
symmetry reduction scheme for such systems by combining the method of slices with
invariant polynomial methods, and show how it works by applying it to the Kuramoto–Sivashinsky
system in one spatial dimension. As an example, we track a relative periodic orbit
through a sequence of bifurcations to the onset of chaos. Within the symmetry-reduced
state space we are able to compute and visualize the unstable manifolds of relative
periodic orbits, their torus bifurcations, a transition to chaos via torus breakdown,
and heteroclinic connections between various relative periodic orbits. It would
be very hard to carry through such analysis in the full state space, without a
symmetry reduction such as the one we present here.

text: Bacterial cytokinesis is commonly initiated by the Z-ring, a dynamic cytoskeletal
structure that assembles at the site of division. Its primary component is FtsZ,
a tubulin-like GTPase, that like its eukaryotic relative forms protein filaments
in the presence of GTP. Since the discovery of the Z-ring 25 years ago, various
models for the role of FtsZ have been suggested. However, important information
about the architecture and dynamics of FtsZ filaments during cytokinesis is still
missing. One reason for this lack of knowledge has been the small size of bacteria,
which has made it difficult to resolve the orientation and dynamics of individual
FtsZ filaments in the Z-ring. While superresolution microscopy experiments have
helped to gain more information about the organization of the Z-ring in the dividing
cell, they were not yet able to elucidate a mechanism of how FtsZ filaments reorganize
during assembly and disassembly of the Z-ring. In this chapter, we explain how
to use an in vitro reconstitution approach to investigate the self-organization
of FtsZ filaments recruited to a biomimetic lipid bilayer by its membrane anchor
FtsA. We show how to perform single-molecule experiments to study the behavior
of individual FtsZ monomers during the constant reorganization of the FtsZ-FtsA
filament network. We describe how to analyze the dynamics of single molecules
and explain why this information can help to shed light onto possible mechanism
of Z-ring constriction. We believe that similar experimental approaches will be
useful to study the mechanism of membrane-based polymerization of other cytoskeletal
systems, not only from prokaryotic but also eukaryotic origin.

text: We establish the dimension and irreducibility of the moduli space of rational
curves (of fixed degree) on arbitrary smooth hypersurfaces of sufficiently low
degree. A spreading out argument reduces the problem to hypersurfaces defined
over finite fields of large cardinality, which can then be tackled using a function
field version of the Hardy-Littlewood circle method, in which particular care
is taken to ensure uniformity in the size of the underlying finite field.

text: We generalise Birch's seminal work on forms in many variables to handle a
system of forms in which the degrees need not all be the same. This allows us
to prove the Hasse principle, weak approximation, and the Manin-Peyre conjecture
for a smooth and geometrically integral variety X Pm, provided only that its dimension
is large enough in terms of its degree.

text: We show that any subset of the squares of positive relative upper density
contains nontrivial solutions to a translation-invariant linear equation in five
or more variables, with explicit quantitative bounds. As a consequence, we establish
the partition regularity of any diagonal quadric in five or more variables whose
coefficients sum to zero. Unlike previous approaches, which are limited to equations
in seven or more variables, we employ transference technology of Green to import
bounds from the linear setting.

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.

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.
