text: Multidimensional Scaling (MDS) is one of the most popular methods for dimensionality
reduction and visualization of high dimensional data. Apart from these tasks,
it also found applications in the field of geometry processing for the analysis
and reconstruction of non-rigid shapes. In this regard, MDS can be thought of
as a shape from metric algorithm, consisting of finding a configuration of points
in the Euclidean space that realize, as isometrically as possible, some given
distance structure. In the present work we cast the least squares variant of MDS
(LS-MDS) in the spectral domain. This uncovers a multiresolution property of distance
scaling which speeds up the optimization by a significant amount, while producing
comparable, and sometimes even better, embeddings.

text: With increasingly sophisticated Diffusion Weighted MRI acquisition methods
and modeling techniques, very large sets of streamlines (fibers) are presently
generated per imaged brain. These reconstructions of white matter architecture,
which are important for human brain research and pre-surgical planning, require
a large amount of storage and are often unwieldy and difficult to manipulate and
analyze. This work proposes a novel continuous parsimonious framework in which
signals are sparsely represented in a dictionary with continuous atoms. The significant
innovation in our new methodology is the ability to train such continuous dictionaries,
unlike previous approaches that either used pre-fixed continuous transforms or
training with finite atoms. This leads to an innovative fiber representation method,
which uses Continuous Dictionary Learning to sparsely code each fiber with high
accuracy. This method is tested on numerous tractograms produced from the Human
Connectome Project data and achieves state-of-the-art performances in compression
ratio and reconstruction error.

text: We present ASIST, a technique for transforming point clouds by replacing objects
with their semantically equivalent counterparts. Transformations of this kind
have applications in virtual reality, repair of fused scans, and robotics. ASIST
is based on a unified formulation of semantic labeling and object replacement;
both result from minimizing a single objective. We present numerical tools for
the efficient solution of this optimization problem. The method is experimentally
assessed on new datasets of both synthetic and real point clouds, and is additionally
compared to two recent works on object replacement on data from the corresponding
papers.

text: The sliding clamp, PCNA, plays a central role in DNA replication and repair.
In the moving replication fork, PCNA is present at the leading strand and at each
of the Okazaki fragments that are formed on the lagging strand. PCNA enhances
the processivity of the replicative polymerases and provides a landing platform
for other proteins and enzymes. The loading of the clamp onto DNA is performed
by the Replication Factor C (RFC) complex, whereas its unloading can be carried
out by an RFC-like complex containing Elg1. Mutations in ELG1 lead to DNA damage
sensitivity and genome instability. To characterize the role of Elg1 in maintaining
genomic integrity, we used homology modeling to generate a number of site-specific
mutations in ELG1 that exhibit different PCNA unloading capabilities. We show
that the sensitivity to DNA damaging agents and hyper-recombination of these alleles
correlate with their ability to unload PCNA from the chromatin. Our results indicate
that retention of modified and unmodified PCNA on the chromatin causes genomic
instability. We also show, using purified proteins, that the Elg1 complex inhibits
DNA synthesis by unloading SUMOylated PCNA from the DNA. Additionally, we find
that mutations in ELG1 suppress the sensitivity of rad5Δ mutants to DNA damage
by allowing trans-lesion synthesis to take place. Taken together, the data indicate
that the Elg1–RLC complex plays an important role in the maintenance of genomic
stability by unloading PCNA from the chromatin.

text: Recent studies validated the feasibility of estimating heart rate from human
faces in RGB video. However, test subjects are often recorded under controlled
conditions, as illumination variations significantly affect the RGB-based heart
rate estimation accuracy. Intel newly-announced low-cost RealSense 3D (RGBD) camera
is becoming ubiquitous in laptops and mobile devices starting this year, opening
the door to new and more robust computer vision. RealSense cameras produce RGB
images with extra depth information inferred from a latent near-infrared (NIR)
channel. In this paper, we experimentally demonstrate, for the first time, that
heart rate can be reliably estimated from RealSense near-infrared images. This
enables illumination invariant heart rate estimation, extending the heart rate
from video feasibility to low-light applications, such as night driving. With
the (coming) ubiquitous presence of RealSense devices, the proposed method not
only utilizes its near-infrared channel, designed originally to be hidden from
consumers; but also exploits the associated depth information for improved robustness
to head pose.

correspondence between deformable shapes performed entirely in the spectral domain.
Our technique relies on the recently introduced partial functional maps formalism
and on the joint approximate diagonalization (JAD) of the Laplace-Beltrami operators
previously introduced for matching non-isometric shapes. We show that a variant
of the JAD problem with an appropriately modified coupling term (surprisingly)
allows to construct quasi-harmonic bases localized on the latent corresponding
parts. This circumvents the need to explicitly compute the unknown parts by means
of the cumbersome alternating minimization used in the previous approaches, and
allows performing all the calculations in the spectral domain with constant complexity
independent of the number of shape vertices. We provide an extensive evaluation
of the proposed technique on standard non-rigid correspondence benchmarks and
show state-of-the-art performance in various settings, including partiality and
the presence of topological noise.

text: "Notions of similarity and correspondence between geometric shapes and images
are central to many tasks in geometry processing, computer vision, and computer
graphics. The goal of this course is to familiarize the audience with a set of
recent techniques that greatly facilitate the computation of mappings or correspondences
between geometric datasets, such as 3D shapes or 2D images by formulating them
as mappings between functions rather than points or triangles.\r\nMethods based
on the functional map framework have recently led to state-of-the-art results
in problems as diverse as non-rigid shape matching, image co-segmentation and
even some aspects of tangent vector field design. One challenge in adopting these
methods in practice, however, is that their exposition often assumes a significant
amount of background in geometry processing, spectral methods and functional analysis,
which can make it difficult to gain an intuition about their performance or about
their applicability to real-life problems. In this course, we try to provide all
the tools necessary to appreciate and use these techniques, while assuming very
little background knowledge. We also give a unifying treatment of these techniques,
which may be difficult to extract from the individual publications and, at the
same time, hint at the generality of this point of view, which can help tackle
many problems in the analysis and creation of visual content.\r\nThis course is
structured as a half day course. We will assume that the participants have knowledge
of basic linear algebra and some knowledge of differential geometry, to the extent
of being familiar with the concepts of a manifold and a tangent vector space.
We will discuss in detail the functional approach to finding correspondences between
non-rigid shapes, the design and analysis of tangent vector fields on surfaces,
consistent map estimation in networks of shapes and applications to shape and
image segmentation, shape variability analysis, and other areas."

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: Engineering and enhancing the breaking of inversion symmetry in solids—that
is, allowing electrons to differentiate between ‘up’ and ‘down’—is a key goal
in condensed-matter physics and materials science because it can be used to stabilize
states that are of fundamental interest and also have potential practical applications.
Examples include improved ferroelectrics for memory devices and materials that
host Majorana zero modes for quantum computing1,2. Although inversion symmetry
is naturally broken in several crystalline environments, such as at surfaces and
interfaces, maximizing the influence of this effect on the electronic states of
interest remains a challenge. Here we present a mechanism for realizing a much
larger coupling of inversion-symmetry breaking to itinerant surface electrons
than is typically achieved. The key element is a pronounced asymmetry of surface
hopping energies—that is, a kinetic-energy-coupled inversion-symmetry breaking,
the energy scale of which is a substantial fraction of the bandwidth. Using spin-
and angle-resolved photoemission spectroscopy, we demonstrate that such a strong
inversion-symmetry breaking, when combined with spin–orbit interactions, can mediate
Rashba-like3,4 spin splittings that are much larger than would typically be expected.
The energy scale of the inversion-symmetry breaking that we achieve is so large
that the spin splitting in the CoO2- and RhO2-derived surface states of delafossite
oxides becomes controlled by the full atomic spin–orbit coupling of the 3d and
4d transition metals, resulting in some of the largest known Rashba-like3,4 spin
splittings. The core structural building blocks that facilitate the bandwidth-scaled
inversion-symmetry breaking are common to numerous materials. Our findings therefore
provide opportunities for creating spin-textured states and suggest routes to
interfacial control of inversion-symmetry breaking in designer heterostructures
of oxides and other material classes.
