text: Multielectron spin qubits are demonstrated, and performance examined by comparing
coherent exchange oscillations in coupled single-electron and multielectron quantum
dots, measured in the same device. Fast (>1 GHz) exchange oscillations with
a quality factor Q∼15 are found for the multielectron case, compared to Q∼2 for
the single-electron case, the latter consistent with experiments in the literature.
A model of dephasing that includes voltage and hyperfine noise is developed that
is in good agreement with both single- and multielectron data, though in both
cases additional exchange-independent dephasing is needed to obtain quantitative
agreement across a broad parameter range.

text: Correlative microscopy incorporates the specificity of fluorescent protein
labeling into high-resolution electron micrographs. Several approaches exist for
correlative microscopy, most of which have used the green fluorescent protein
(GFP) as the label for light microscopy. Here we use chemical tagging and synthetic
fluorophores instead, in order to achieve protein-specific labeling, and to perform
multicolor imaging. We show that synthetic fluorophores preserve their post-embedding
fluorescence in the presence of uranyl acetate. Post-embedding fluorescence is
of such quality that the specimen can be prepared with identical protocols for
scanning electron microscopy (SEM) and transmission electron microscopy (TEM);
this is particularly valuable when singular or otherwise difficult samples are
examined. We show that synthetic fluorophores give bright, well-resolved signals
in super-resolution light microscopy, enabling us to superimpose light microscopic
images with a precision of up to 25 nm in the x–y plane on electron micrographs.
To exemplify the preservation quality of our new method we visualize the molecular
arrangement of cadherins in adherens junctions of mouse epithelial cells.

text: Fractionation of isotopes among distinct molecules or phases is a quantum
effect which is often exploited to obtain insights on reaction mechanisms, biochemical,
geochemical, and atmospheric phenomena. Accurate evaluation of isotope ratios
in atomistic simulations is challenging, because one needs to perform a thermodynamic
integration with respect to the isotope mass, along with time-consuming path integral
calculations. By re-formulating the problem as a particle exchange in the ring
polymer partition function, we derive new estimators giving direct access to the
differential partitioning of isotopes, which can simplify the calculations by
avoiding thermodynamic integration. We demonstrate the efficiency of these estimators
by applying them to investigate the isotope fractionation ratios in the gas-phase
Zundel cation, and in a few simple hydrocarbons.

text: It is well known that ultrasonic vibration can soften metals, and this phenomenon
has been widely exploited in industrial applications concerning metal forming
and bonding. Recent experiments show that the simultaneous application of oscillatory
stresses from audible to ultrasonic frequency ranges can lead to not only softening
but also significant dislocation annihilation and subgrain formation in metal
samples from the nano- to macro-size range. These findings indicate that the existing
understanding of ultrasound softening – that the vibrations either impose additional
stress waves to augment the quasi-static applied load, or cause heating of the
metal, whereas the metal’s intrinsic deformation resistance or mechanism remains
unaltered – is far from complete. To understand the softening and the associated
enhanced subgrain formation and dislocation annihilation, a new simulator based
on the dynamics of dislocation-density functions is employed. This new simulator
considers the flux, production and annihilation, as well as the Taylor and elastic
interactions between dislocation densities. Softening during vibrations as well
as enhanced cell formation is predicted. The simulations reveal the main mechanism
for subcell formation under oscillatory loadings to be the enhanced elimination
of statistically stored dislocations (SSDs) by the oscillatory stress, leaving
behind geometrically necessary dislocations with low Schmid factors which then
form the subgrain walls. The oscillatory stress helps the depletion of the SSDs,
because the chance for them to meet up and annihilate is increased with reversals
of dislocation motions. This is the first simulation effort to successfully predict
the cell formation phenomenon under vibratory loadings.

text: 'Protein oligomers have been implicated as toxic agents in a wide range of
amyloid-related diseases. However, it has remained unsolved whether the oligomers
are a necessary step in the formation of amyloid fibrils or just a dangerous byproduct.
Analogously, it has not been resolved if the amyloid nucleation process is a classical
one-step nucleation process or a two-step process involving prenucleation clusters.
We use coarse-grained computer simulations to study the effect of nonspecific
attractions between peptides on the primary nucleation process underlying amyloid
fibrillization. We find that, for peptides that do not attract, the classical
one-step nucleation mechanism is possible but only at nonphysiologically high
peptide concentrations. At low peptide concentrations, which mimic the physiologically
relevant regime, attractive interpeptide interactions are essential for fibril
formation. Nucleation then inevitably takes place through a two-step mechanism
involving prefibrillar oligomers. We show that oligomers not only help peptides
meet each other but also, create an environment that facilitates the conversion
of monomers into the β-sheet–rich form characteristic of fibrils. Nucleation typically
does not proceed through the most prevalent oligomers but through an oligomer
size that is only observed in rare fluctuations, which is why such aggregates
might be hard to capture experimentally. Finally, we find that the nucleation
of amyloid fibrils cannot be described by classical nucleation theory: in the
two-step mechanism, the critical nucleus size increases with increases in both
concentration and interpeptide interactions, which is in direct contrast with
predictions from classical nucleation theory.'

text: We use numerical simulations to compute the equation of state of a suspension
of spherical self-propelled nanoparticles in two and three dimensions. We study
in detail the effect of excluded volume interactions and confinement as a function
of the system's temperature, concentration, and strength of the propulsion. We
find a striking nonmonotonic dependence of the pressure on the temperature and
provide simple scaling arguments to predict and explain the occurrence of such
anomalous behavior. We explicitly show how our results have important implications
for the effective forces on passive components suspended in a bath of active particles.

text: Diffraction-unlimited far-field super-resolution fluorescence (nanoscopy)
methods typically rely on transiently transferring fluorophores between two states,
whereby this transfer is usually laid out as a switch. However, depending on whether
this is induced in a spatially controlled manner using a pattern of light (coordinate-targeted)
or stochastically on a single-molecule basis, specific requirements on the fluorophores
are imposed. Therefore, the fluorophores are usually utilized just for one class
of methods only. In this study we demonstrate that the reversibly switchable fluorescent
protein Dreiklang enables live-cell recordings in both spatially controlled and
stochastic modes. We show that the Dreiklang chromophore entails three different
light-induced switching mechanisms, namely a reversible photochemical one, off-switching
by stimulated emission, and a reversible transfer to a long-lived dark state from
the S1 state, all of which can be utilized to overcome the diffraction barrier.
We also find that for the single-molecule- based stochastic GSDIM approach (ground-state
depletion followed by individual molecule return), Dreiklang provides a larger
number of on-off localization events as compared to its progenitor Citrine. Altogether,
Dreiklang is a versatile probe for essentially all popular forms of live-cell
fluorescence nanoscopy.

text: While the penetration of objects into granular media is well-studied, there
is little understanding of how objects settle in gravities, geff, different from
that of Earth - a scenario potentially relevant to the geomorphology of planets
and asteroids and also to their exploration using man-made devices. By conducting
experiments in an accelerating frame, we explore geff ranging from 0.4 g to 1.2
g. Surprisingly, we find that the rest depth is independent of geff and also that
the time required for the object to come to rest scales like geff-1/2. With discrete
element modeling simulations, we reproduce the experimental results and extend
the range of geff to objects as small as asteroids and as large as Jupiter. Our
results shed light on the initial stage of sedimentation into dry granular media
across a range of celestial bodies and also have implications for the design of
man-made, extraterrestrial vehicles and structures. Key Points The settling depth
in granular media is independent of gravity The settling time scales like g-1/2
Layering driven by granular sedimentation should be similar.

text: 'The decremental single-source shortest paths (SSSP) problem concerns maintaining
the distances between a given source node s to every node in an n-node m-edge
graph G undergoing edge deletions. While its static counterpart can be easily
solved in near-linear time, this decremental problem is much more challenging
even in the undirected unweighted case. In this case, the classic O(mn) total
update time of Even and Shiloach (JACM 1981) has been the fastest known algorithm
for three decades. With the loss of a (1 + ε)-approximation factor, the running
time was recently improved to O(n 2+o(1) ) by Bernstein and Roditty (SODA 2011),
and more recently to O(n 1.8+o(1) + m 1+o(1) ) by Henzinger, Krinninger, and Nanongkai
(SODA 2014). In this paper, we finally bring the running time of this case down
to near-linear: We give a (1 + ε)-approximation algorithm with O(m 1+o(1) ) total
update time, thus obtaining near-linear time. Moreover, we obtain O(m 1+o(1) log
W) time for the weighted case, where the edge weights are integers from 1 to W.
The only prior work on weighted graphs in o(mn log W) time is the O(mn 0.986 log
W)-time algorithm by Henzinger, Krinninger, and Nanongkai (STOC 2014) which works
for the general weighted directed case. In contrast to the previous results which
rely on maintaining a sparse emulator, our algorithm relies on maintaining a so-called
sparse (d, ε)-hop set introduced by Cohen (JACM 2000) in the PRAM literature.
A (d, ε)-hop set of a graph G = (V, E) is a set E'' of weighted edges such that
the distance between any pair of nodes in G can be (1 + ε)-approximated by their
d-hop distance (given by a path containing at most d edges) on G''=(V, E∪E'').
Our algorithm can maintain an (n o(1) , ε)-hop set of near-linear size in near-linear
time under edge deletions. It is the first of its kind to the best of our knowledge.
To maintain the distances on this hop set, we develop a monotone bounded-hop Even-Shiloach
tree. It results from extending and combining the monotone Even-Shiloach tree
of Henzinger, Krinninger, and Nanongkai (FOCS 2013) with the bounded-hop SSSP
technique of Bernstein (STOC 2013). These two new tools might be of independent
interest.'

text: "We consider dynamic algorithms for maintaining Single-Source Reachability
(SSR) and approximate Single-Source Shortest Paths (SSSP) on n-node m-edge directed
graphs under edge deletions (decremental algorithms). The previous fastest algorithm
for SSR and SSSP goes back three decades to Even and Shiloach (JACM 1981); it
has O(1) query time and O(mn) total update time (i.e., linear amortized update
time if all edges are deleted). This algorithm serves as a building block for
several other dynamic algorithms. The question whether its total update time can
be improved is a major, long standing, open problem.\r\n\r\nIn this paper, we
answer this question affirmatively. We obtain a randomized algorithm which, in
a simplified form, achieves an Õ(mn0.984) expected total update time for SSR and
(1 + ε)-approximate SSSP, where Õ(·) hides poly log n. We also extend our algorithm
to achieve roughly the same running time for Strongly Connected Components (SCC),
improving the algorithm of Roditty and Zwick (FOCS 2002), and an algorithm that
improves the Õ (mn log W)-time algorithm of Bernstein (STOC 2013) for approximating
SSSP on weighted directed graphs, where the edge weights are integers from 1 to
W. All our algorithms have constant query time in the worst case."

text: We present the first deterministic data structures for maintaining approximate
minimum vertex cover and maximum matching in a fully dynamic graph in time per
update. In particular, for minimum vertex cover we provide deterministic data
structures for maintaining a (2 + ε) approximation in O(log n/ε2) amortized time
per update. For maximum matching, we show how to maintain a (3 + e) approximation
in O(m1/3/ε2) amortized time per update, and a (4 + ε) approximation in O(m1/3/ε2)
worst-case time per update. Our data structure for fully dynamic minimum vertex
cover is essentially near-optimal and settles an open problem by Onak and Rubinfeld
[13].

text: "We study dynamic (1 + ∊)-approximation algorithms for the single-source shortest
paths problem in an unweighted undirected n-node m-edge graph under edge deletions.
The fastest algorithm for this problem is an algorithm with O(n2+o(1)) total update
time and constant query time by Bernstein and Roditty (SODA 2011). In this paper,
we improve the total update time to O(n1.8+o(1) + m1+o(1)) while keeping the query
time constant. This running time is essentially tight when m = Ω(n1.8) since we
need Ω(m) time even in the static setting. For smaller values of m, the running
time of our algorithm is subquadratic, and is the first that breaks through the
quadratic time barrier.\r\n\r\nIn obtaining this result, we develop a fast algorithm
for what we call center cover data structure. We also make non-trivial extensions
to our previous techniques called lazy-update and monotone Even-Shiloach trees
(ICALP 2013 and FOCS 2013). As by-products of our new techniques, we obtain two
new results for the decremental all-pairs shortest-paths problem. Our first result
is the first approximation algorithm whose total update time is faster than Õ(mn)
for all values of m. Our second result is a new trade-off between the total update
time and the additive approximation guarantee."

text: Observations of flowing granular matter have suggested that same-material
tribocharging depends on particle size, typically rendering large grains positive
and small ones negative. Models assuming the transfer of trapped electrons can
account for this trend, but have not been validated. Tracking individual grains
in an electric field, we show quantitatively that charge is transferred based
on size between materially identical grains. However, the surface density of trapped
electrons, measured independently by thermoluminescence techniques, is orders
of magnitude too small to account for the scale of charge transferred. This reveals
that trapped electrons are not a necessary ingredient for same-material tribocharging.

text: An experimentally easy to perform method for the generation of alumina-supported
Fe3O4 nanoparticles [(6±1) nm size, 0.67 wt %]and the use of this material in
hydrazine-mediated heterogeneously catalyzed reductions of nitroarenes to anilines
under batch and continuous-flow conditions is presented. The bench-stable, reusable
nano-Fe3O4@Al2O3 catalyst can selectively reduce functionalized nitroarenes at
1 mol % catalyst loading by using a 20 mol % excess of hydrazine hydrate in an
elevated temperature regime (150 °C, reaction time 2–6 min in batch). For continuous-flow
processing, the catalyst material is packed into dedicated cartridges and used
in a commercially available high-temperature/-pressure flow device. In continuous
mode, reaction times can be reduced to less than 1 min at 150 °C (30 bar back
pressure) in a highly intensified process. The nano-Fe3O4@Al2O3 catalyst demonstrated
stable reduction of nitrobenzene (0.5 M in MeOH) for more than 10 h on stream
at a productivity of 30 mmol h−1 (0.72 mol per day). Importantly, virtually no
leaching of the catalytically active material could be observed by inductively
coupled plasma MS monitoring.

text: 'Membrane phospholipids typically contain fatty acids (FAs) of 16 and 18 carbon
atoms. This particular chain length is evolutionarily highly conserved and presumably
provides maximum stability and dynamic properties to biological membranes in response
to nutritional or environmental cues. Here, we show that the relative proportion
of C16 versus C18 FAs is regulated by the activity of acetyl-CoA carboxylase (Acc1),
the first and rate-limiting enzyme of FA de novo synthesis. Acc1 activity is attenuated
by AMPK/Snf1-dependent phosphorylation, which is required to maintain an appropriate
acyl-chain length distribution. Moreover, we find that the transcriptional repressor
Opi1 preferentially binds to C16 over C18 phosphatidic acid (PA) species: thus,
C16-chain containing PA sequesters Opi1 more effectively to the ER, enabling AMPK/Snf1
control of PA acyl-chain length to determine the degree of derepression of Opi1
target genes. These findings reveal an unexpected regulatory link between the
major energy-sensing kinase, membrane lipid composition, and transcription.'

text: We investigate the performance of five glacier melt models over a multi-decadal
period in order to assess their ability to model future glacier response. The
models range from a simple degree-day model, based solely on air temperature,
to more-sophisticated models, including the full shortwave radiation balance.
In addition to the empirical models, the performance of a physically based energy-balance
(EB) model is examined. The melt models are coupled to an accumulation and a surface
evolution model and applied in a distributed manner to Rhonegletscher, Switzerland,
over the period 1929–2012 at hourly resolution. For calibration, seasonal mass-balance
measurements (2006–12) are used. Decadal ice volume changes for six periods in
the years 1929–2012 serve for model validation. Over the period 2006–12, there
are almost no differences in performance between the models, except for EB, which
is less consistent with observations, likely due to lack of meteorological in
situ data. However, simulations over the long term (1929–2012) reveal that models
which include a separate term for shortwave radiation agree best with the observed
ice volume changes, indicating that their melt relationships are robust in time
and thus suitable for long-term modelling, in contrast to more empirical approaches
that are oversensitive to temperature fluctuations.

text: 'Glaciers in the Andes of Chile seem to be shrinking and possibly loosing
mass, but the number and types of studies conducted, constrained mainly by data
availability, are not sufficient to provide a synopsis of glacier changes for
the past or future or explain in an explicit way causes of the observed changes.
In this paper, we provide a systematic review of changes in glaciers for the entire
country, followed by a discussion of the studies that have provided evidence of
such changes. We identify a missing type of work in distributed, physically-oriented
modelling studies that are needed to bridge the gap between the numerous remote
sensing studies and the specific, point scale works focused on process understanding.
We use an advanced mass balance model applied to one of the best monitored glaciers
in the region to investigate four main research issues that should be addressed
in modelling studies for a sound assessment of glacier changes: 1) the use of
physically-based models of glacier ablation (energy balance models) versus more
empirical models (enhanced temperature index approaches); 2) the importance of
the correct extrapolation of air temperature forcing on glaciers and in high elevation
areas and the large uncertainty in model outputs associated with it; 3) the role
played by snow gravitational redistribution; and 4) the uncertainty associated
with future climate scenarios. We quantify differences in model outputs associated
with each of these choices, and conclude with suggestions for future work directions.'

text: 'Switzerland is one of the countries with some of the longest and best glaciological
data sets. Its glaciers and their changes in response to climate have been extensively
investigated, and the number and quality of related studies are notable. However,
a comprehensive review of glacier changes and their impact on the hydrology of
glacierised catchments for Switzerland is missing and we use the opportunity provided
by the EU-FP7 ACQWA project to review the current state of knowledge about past
changes and future projections. We examine the type of models that have been applied
to infer glacier evolution and identify knowledge gaps that should be addressed
in future research in addition to those indicated in previous publications. Common
characteristics in long-term series of projected future glacier runoff are an
initial peak followed by a decline, associated with shifts in seasonality, earlier
melt onset and reduced summer runoff. However, the quantitative predictions are
difficult to compare, as studies differ in terms of model structure, calibration
strategies, input data, temporal and spatial resolution as well as future scenarios
used for impact studies. We identify two sources of uncertainties among those
emerging from recent research, and use simulations over four glaciers to: i) quantify
the importance of the correct extrapolation of air temperature, and ii) point
at the key role played by debris cover in modulating glacier response.'

text: Himalayan glacier tongues are commonly debris covered and they are an important
source of melt water. However, they remain relatively unstudied because of the
inaccessibility of the terrain and the difficulties in field work caused by the
thick debris mantles. Observations of debris-covered glaciers are therefore scarce
and airborne remote sensing may bridge the gap between scarce field observations
and coarse resolution space-borne remote sensing. In this study we deploy an Unmanned
Aerial Vehicle (UAV) before and after the melt and monsoon season (May and October
2013) over the debris-covered tongue of the Lirung Glacier in Nepal. Based on
stereo-imaging and the structure for motion algorithm we derive highly detailed
ortho-mosaics and digital elevation models (DEMs), which we geometrically correct
using differential GPS observations collected in the field. Based on DEM differencing
and manual feature tracking we derive the mass loss and the surface velocity of
the glacier at a high spatial accuracy. On average, mass loss is limited and the
surface velocity is very small. However, the spatial variability of melt rates
is very high, and ice cliffs and supra-glacial ponds show mass losses that can
be an order of magnitude higher than the average. We suggest that future research
should focus on the interaction between supra-glacial ponds, ice cliffs and englacial
hydrology to further understand the dynamics of debris-covered glaciers. Finally,
we conclude that UAV deployment has large potential in glaciology and it may revolutionize
methods currently applied in studying glacier surface features.
