text: We have observed a sample of typical z ∼ 1 star-forming galaxies, selected
from the HiZELS survey, with the new K-band Multi-Object Spectrograph (KMOS) near-infrared,
multi-integral field unit instrument on the Very Large Telescope (VLT), in order
to obtain their dynamics and metallicity gradients. The majority of our galaxies
have a metallicity gradient consistent with being flat or negative (i.e. higher
metallicity cores than outskirts). Intriguingly, we find a trend between metallicity
gradient and specific star formation rate (sSFR), such that galaxies with a high
sSFR tend to have relatively metal poor centres, a result which is strengthened
when combined with data sets from the literature. This result appears to explain
the discrepancies reported between different high-redshift studies and varying
claims for evolution. From a galaxy evolution perspective, the trend we see would
mean that a galaxy's sSFR is governed by the amount of metal-poor gas that can
be funnelled into its core, triggered either by merging or through efficient accretion.
In fact, merging may play a significant role as it is the starburst galaxies at
all epochs, which have the more positive metallicity gradients. Our results may
help to explain the origin of the fundamental metallicity relation, in which galaxies
at a fixed mass are observed to have lower metallicities at higher star formation
rates, especially if the metallicity is measured in an aperture encompassing only
the central regions of the galaxy. Finally, we note that this study demonstrates
the power of KMOS as an efficient instrument for large-scale resolved galaxy surveys.

text: 'Candidate galaxies at redshifts of z ∼ 10 are now being found in extremely
deep surveys, probing very small areas. As a consequence, candidates are very
faint, making spectroscopic confirmation practically impossible. In order to overcome
such limitations, we have undertaken the CF-HiZELS survey, which is a large-area,
medium-depth near-infrared narrow-band survey targeted at z = 8.8 Lyman α (Lyα)
emitters (LAEs) and covering 10 deg2 in part of the SSA22 field with the Canada–France–Hawaii
Telescope (CFHT). We surveyed a comoving volume of 4.7 × 106 Mpc3 to a Lyα luminosity
limit of 6.3 × 1043舁erg舁s−1. We look for Lyα candidates by applying the following
criteria: (i) clear emission-line source, (ii) no optical detections (ugriz from
CFHTLS), (iii) no visible detection in the optical stack (ugriz > 27), (iv) visually
checked reliable NBJ and J detections and (v) J − K ≤ 0. We compute photometric
redshifts and remove a significant amount of dusty lower redshift line-emitters
at z ∼ 1.4 or 2.2. A total of 13 Lyα candidates were found, of which two are marked
as strong candidates, but the majority have very weak constraints on their spectral
energy distributions. Using follow-up observations with SINFONI/VLT, we are able
to exclude the most robust candidates as LAEs. We put a strong constraint on the
Lyα luminosity function at z ∼ 9 and make realistic predictions for ongoing and
future surveys. Our results show that surveys for the highest redshift LAEs are
susceptible of multiple contaminations and that spectroscopic follow-up is absolutely
necessary.'

text: We report on the magnetic properties of a hot-pressed FeSb 2 sample. We find
a significant increase in the magnetic susceptibility in our sample when compared
with the values previously reported for the polycrystalline sample. The pronounced
Curie tail at low temperature corresponds to 0.2% of Fe 2+ impurities per mole.
In the intrinsic conductivity region, the susceptibility due to free carriers
shows thermally activated behavior and is consistent with the data reported for
single crystal FeSb 2 . Based on our data and analysis, while the enhanced magnetic
susceptibility in our sample comes mainly from a small amount of unreacted Fe,
the contribution from the enhanced carrier density due to lattice and strain defects
arising from the ball milling process is also significant. Existence of an unreacted
Fe phase is evidenced by small coercivity values of ~100 observed at 50 and 300
K.

text: "We study a weighted online bipartite matching problem: G(V 1, V 2, E) is
a weighted bipartite graph where V 1 is known beforehand and the vertices of V
2 arrive online. The goal is to match vertices of V 2 as they arrive to vertices
in V 1, so as to maximize the sum of weights of edges in the matching. If assignments
to V 1 cannot be changed, no bounded competitive ratio is achievable. We study
the weighted online matching problem with free disposal, where vertices in V 1
can be assigned multiple times, but only get credit for the maximum weight edge
assigned to them over the course of the algorithm. For this problem, the greedy
algorithm is 0.5-competitive and determining whether a better competitive ratio
is achievable is a well known open problem.\r\n\r\nWe identify an interesting
special case where the edge weights are decomposable as the product of two factors,
one corresponding to each end point of the edge. This is analogous to the well
studied related machines model in the scheduling literature, although the objective
functions are different. For this case of decomposable edge weights, we design
a 0.5664 competitive randomized algorithm in complete bipartite graphs. We show
that such instances with decomposable weights are non-trivial by establishing
upper bounds of 0.618 for deterministic and 0.8 for randomized algorithms.\r\n\r\nA
tight competitive ratio of 1 − 1/e ≈ 0.632 was known previously for both the 0-1
case as well as the case where edge weights depend on the offline vertices only,
but for these cases, reassignments cannot change the quality of the solution.
Beating 0.5 for weighted matching where reassignments are necessary has been a
significant challenge. We thus give the first online algorithm with competitive
ratio strictly better than 0.5 for a non-trivial case of weighted matching with
free disposal."

text: "Assume a seller wants to sell a digital product in a social network where
a buyer’s valuation of the item has positive network externalities from her neighbors
that already have the item. The goal of the seller is to maximize his revenue.
Previous work on this problem [7] studies the case where clients are offered the
item in sequence and have to pay personalized prices. This is highly infeasible
in large scale networks such as the Facebook graph: (1) Offering items to the
clients one after the other consumes a large amount of time, and (2) price-discrimination
of clients could appear unfair to them and result in negative client reaction
or could conflict with legal requirements.\r\n\r\nWe study a setting dealing with
these issues. Specifically, the item is offered in parallel to multiple clients
at the same time and at the same price. This is called a round. We show that with
O(logn) rounds, where n is the number of clients, a constant factor of the revenue
with price discrimination can be achieved and that this is not possible with o(logn)
rounds. Moreover we show that it is APX-hard to maximize the revenue and we give
constant factor approximation algorithms for various further settings of limited
price discrimination."

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: Multi-dimensional mean-payoff and energy games provide the mathematical foundation
for the quantitative study of reactive systems, and play a central role in the
emerging quantitative theory of verification and synthesis. In this work, we study
the strategy synthesis problem for games with such multi-dimensional objectives
along with a parity condition, a canonical way to express ω ω -regular conditions.
While in general, the winning strategies in such games may require infinite memory,
for synthesis the most relevant problem is the construction of a finite-memory
winning strategy (if one exists). Our main contributions are as follows. First,
we show a tight exponential bound (matching upper and lower bounds) on the memory
required for finite-memory winning strategies in both multi-dimensional mean-payoff
and energy games along with parity objectives. This significantly improves the
triple exponential upper bound for multi energy games (without parity) that could
be derived from results in literature for games on vector addition systems with
states. Second, we present an optimal symbolic and incremental algorithm to compute
a finite-memory winning strategy (if one exists) in such games. Finally, we give
a complete characterization of when finite memory of strategies can be traded
off for randomness. In particular, we show that for one-dimension mean-payoff
parity games, randomized memoryless strategies are as powerful as their pure finite-memory
counterparts.

text: A robust combiner for hash functions takes two candidate implementations and
constructs a hash function which is secure as long as at least one of the candidates
is secure. So far, hash function combiners only aim at preserving a single property
such as collision-resistance or pseudorandomness. However, when hash functions
are used in protocols like TLS they are often required to provide several properties
simultaneously. We therefore put forward the notion of robust multi-property combiners
and elaborate on different definitions for such combiners. We then propose a combiner
that provably preserves (target) collision-resistance, pseudorandomness, and being
a secure message authentication code. This combiner satisfies the strongest notion
we propose, which requires that the combined function satisfies every security
property which is satisfied by at least one of the underlying hash function. If
the underlying hash functions have output length n, the combiner has output length
2 n. This basically matches a known lower bound for black-box combiners for collision-resistance
only, thus the other properties can be achieved without penalizing the length
of the hash values. We then propose a combiner which also preserves the property
of being indifferentiable from a random oracle, slightly increasing the output
length to 2 n+ω(log n). Moreover, we show how to augment our constructions in
order to make them also robust for the one-wayness property, but in this case
require an a priory upper bound on the input length.

text: Adaptation in the retina is thought to optimize the encoding of natural light
signals into sequences of spikes sent to the brain. While adaptive changes in
retinal processing to the variations of the mean luminance level and second-order
stimulus statistics have been documented before, no such measurements have been
performed when higher-order moments of the light distribution change. We therefore
measured the ganglion cell responses in the tiger salamander retina to controlled
changes in the second (contrast), third (skew) and fourth (kurtosis) moments of
the light intensity distribution of spatially uniform temporally independent stimuli.
The skew and kurtosis of the stimuli were chosen to cover the range observed in
natural scenes. We quantified adaptation in ganglion cells by studying linear-nonlinear
models that capture well the retinal encoding properties across all stimuli. We
found that the encoding properties of retinal ganglion cells change only marginally
when higher-order statistics change, compared to the changes observed in response
to the variation in contrast. By analyzing optimal coding in LN-type models, we
showed that neurons can maintain a high information rate without large dynamic
adaptation to changes in skew or kurtosis. This is because, for uncorrelated stimuli,
spatio-temporal summation within the receptive field averages away non-gaussian
aspects of the light intensity distribution.
