text: Although studies on laboratory species and natural populations of vertebrates
have shown reproduction to impair later performance, little is known of the age‐specific
associations between reproduction and survival, and how such findings apply to
the ageing of large, long‐lived species. Herein we develop a framework to examine
population‐level patterns of reproduction and survival across lifespan in long‐lived
organisms, and decompose those changes into individual‐level effects, and the
effects of age‐specific trade‐offs between fitness components. We apply this to
an extensive longitudinal dataset on female semi‐captive Asian timber elephants
(Elephas maximus) and report the first evidence of age‐specific fitness declines
that are driven by age‐specific associations between fitness components in a long‐lived
mammal. Associations between reproduction and survival are positive in early life,
but negative in later life with up to 71% of later‐life survival declines associated
with investing in the production of offspring within this population of this critically
endangered species.

text: We present an analysis of finite-size effects in jammed packings of N soft,
frictionless spheres at zero temperature. There is a 1/N correction to the discrete
jump in the contact number at the transition so that jammed packings exist only
above isostaticity. As a result, the canonical power-law scalings of the contact
number and elastic moduli break down at low pressure. These quantities exhibit
scaling collapse with a nontrivial scaling function, demonstrating that the jamming
transition can be considered a phase transition. Scaling is achieved as a function
of N in both two and three dimensions, indicating an upper critical dimension
of 2.

text: Fungal cell walls frequently contain a polymer of mannose and galactose called
galactomannan. In the pathogenic filamentous fungus Aspergillus fumigatus, this
polysaccharide is made of a linear mannan backbone with side chains of galactofuran
and is anchored to the plasma membrane via a glycosylphosphatidylinositol or is
covalently linked to the cell wall. To date, the biosynthesis and significance
of this polysaccharide are unknown. The present data demonstrate that deletion
of the Golgi UDP-galactofuranose transporter GlfB or the GDP-mannose transporter
GmtA leads to the absence of galactofuran or galactomannan, respectively. This
indicates that the biosynthesis of galactomannan probably occurs in the lumen
of the Golgi apparatus and thus contrasts with the biosynthesis of other fungal
cell wall polysaccharides studied to date that takes place at the plasma membrane.
Transglycosylation of galactomannan from the membrane to the cell wall is hypothesized
because both the cell wall-bound and membrane-bound polysaccharide forms are affected
in the generated mutants. Considering the severe growth defect of the A. fumigatus
GmtA-deficient mutant, proving this paradigm might provide new targets for antifungal
therapy.

text: In dynamical models of cortical networks, the recurrent connectivity can amplify
the input given to the network in two distinct ways. One is induced by the presence
of near-critical eigenvalues in the connectivity matrix W, producing large but
slow activity fluctuations along the corresponding eigenvectors (dynamical slowing).
The other relies on W not being normal, which allows the network activity to make
large but fast excursions along specific directions. Here we investigate the trade-off
between non-normal amplification and dynamical slowing in the spontaneous activity
of large random neuronal networks composed of excitatory and inhibitory neurons.
We use a Schur decomposition of W to separate the two amplification mechanisms.
Assuming linear stochastic dynamics, we derive an exact expression for the expected
amount of purely non-normal amplification. We find that amplification is very
limited if dynamical slowing must be kept weak. We conclude that, to achieve strong
transient amplification with little slowing, the connectivity must be structured.
We show that unidirectional connections between neurons of the same type together
with reciprocal connections between neurons of different types, allow for amplification
already in the fast dynamical regime. Finally, our results also shed light on
the differences between balanced networks in which inhibition exactly cancels
excitation and those where inhibition dominates.

text: Using correlated live-cell imaging and electron tomography we found that actin
branch junctions in protruding and treadmilling lamellipodia are not concentrated
at the front as previously supposed, but link actin filament subsets in which
there is a continuum of distances from a junction to the filament plus ends, for
up to at least 1 mm. When branch sites were observed closely spaced on the same
filament their separation was commonly a multiple of the actin helical repeat
of 36 nm. Image averaging of branch junctions in the tomograms yielded a model
for the in vivo branch at 2.9 nm resolution, which was comparable with that derived
for the in vitro actin- Arp2/3 complex. Lamellipodium initiation was monitored
in an intracellular wound-healing model and was found to involve branching from
the sides of actin filaments oriented parallel to the plasmalemma. Many filament
plus ends, presumably capped, terminated behind the lamellipodium tip and localized
on the dorsal and ventral surfaces of the actin network. These findings reveal
how branching events initiate and maintain a network of actin filaments of variable
length, and provide the first structural model of the branch junction in vivo.
A possible role of filament capping in generating the lamellipodium leaflet is
discussed and a mathematical model of protrusion is also presented.

text: The spatial organization of cell fates during development involves the interpretation
of morphogen gradients by cellular signaling cascades and transcriptional networks.
Recent studies use biophysical models, genetics, and quantitative imaging to unravel
how tissue-level morphogen behavior arises from subcellular events. Moreover,
data from several systems show that morphogen gradients, downstream signaling,
and the activity of cell-intrinsic transcriptional networks change dynamically
during pattern formation. Studies from Drosophila and now also vertebrates suggest
that transcriptional network dynamics are central to the generation of gene expression
patterns. Together, this leads to the view that pattern formation is an emergent
behavior that results from the coordination of events occurring across molecular,
cellular, and tissue scales. The development of novel approaches to study this
complex process remains a challenge.

text: We report on the electronic transport properties of multiple-gate devices
fabricated from undoped silicon nanowires. Understanding and control of the relevant
transport mechanisms was achieved by means of local electrostatic gating and temperature-dependent
measurements. The roles of the source/drain contacts and of the silicon channel
could be independently evaluated and tuned. Wrap gates surrounding the silicide-silicon
contact interfaces were proved to be effective in inducing a full suppression
of the contact Schottky barriers, thereby enabling carrier injection down to liquid
helium temperature. By independently tuning the effective Schottky barrier heights,
a variety of reconfigurable device functionalities could be obtained. In particular,
the same nanowire device could be configured to work as a Schottky barrier transistor,
a Schottky diode, or a p-n diode with tunable polarities. This versatility was
eventually exploited to realize a NAND logic gate with gain well above one.

text: Self-assembled Ge wires with a height of only 3 unit cells and a length of
up to 2 micrometers were grown on Si(001) by means of a catalyst-free method based
on molecular beam epitaxy. The wires grow horizontally along either the [100]
or the [010] direction. On atomically flat surfaces, they exhibit a highly uniform,
triangular cross section. A simple thermodynamic model accounts for the existence
of a preferential base width for longitudinal expansion, in quantitative agreement
with the experimental findings. Despite the absence of intentional doping, the
first transistor-type devices made from single wires show low-resistive electrical
contacts and single-hole transport at sub-Kelvin temperatures. In view of their
exceptionally small and self-defined cross section, these Ge wires hold promise
for the realization of hole systems with exotic properties and provide a new development
route for silicon-based nanoelectronics.

text: We studied the low-energy states of spin-1/2 quantum dots defined in InAs/InP
nanowires and coupled to aluminum superconducting leads. By varying the superconducting
gap Δ with a magnetic field B we investigated the transition from strong coupling
Δ≪T K to weak-coupling Δ≫T K, where T K is the Kondo temperature. Below the critical
field, we observe a persisting zero-bias Kondo resonance that vanishes only for
low B or higher temperatures, leaving the room to more robust subgap structures
at bias voltages between Δ and 2Δ. For strong and approximately symmetric tunnel
couplings, a Josephson supercurrent is observed in addition to the Kondo peak.
We ascribe the coexistence of a Kondo resonance and a superconducting gap to a
significant density of intragap quasiparticle states, and the finite-bias subgap
structures to tunneling through Shiba states. Our results, supported by numerical
calculations, own relevance also in relation to tunnel-spectroscopy experiments
aiming at the observation of Majorana fermions in hybrid nanostructures.

text: Steering a quantum harmonic oscillator state along cyclic trajectories leads
to a path-dependent geometric phase. Here we describe its experimental observation
in an electronic harmonic oscillator. We use a superconducting qubit as a nonlinear
probe of the phase, which is otherwise unobservable due to the linearity of the
oscillator. We show that the geometric phase is, for a variety of cyclic paths,
proportional to the area enclosed in the quadrature plane. At the transition to
the nonadiabatic regime, we study corrections to the phase and dephasing of the
qubit caused by qubit-resonator entanglement. In particular, we identify parameters
for which this dephasing mechanism is negligible even in the nonadiabatic regime.
The demonstrated controllability makes our system a versatile tool to study geometric
phases in open quantum systems and to investigate their potential for quantum
information processing.

text: Nonlinearity and entanglement are two important properties by which physical
systems can be identified as nonclassical. We study the dynamics of the resonant
interaction of up to N=3 two-level systems and a single mode of the electromagnetic
field sharing a single excitation dynamically. We observe coherent vacuum Rabi
oscillations and their nonlinear √N speedup by tracking the populations of all
qubits and the resonator in time. We use quantum state tomography to show explicitly
that the dynamics generates maximally entangled states of the W class in a time
limited only by the collective interaction rate. We use an entanglement witness
and the 3-tangle to characterize the state whose fidelity F=78% is limited in
our experiments by crosstalk arising during the simultaneous qubit manipulations
which is absent in a sequential approach with F=91%.

text: A localized qubit entangled with a propagating quantum field is well suited
to study nonlocal aspects of quantum mechanics and may also provide a channel
to communicate between spatially separated nodes in a quantum network. Here, we
report the on-demand generation and characterization of Bell-type entangled states
between a superconducting qubit and propagating microwave fields composed of zero-,
one-, and two-photon Fock states. Using low noise linear amplification and efficient
data acquisition we extract all relevant correlations between the qubit and the
photon states and demonstrate entanglement with high fidelity.

text: Brain circuits are assembled from a large variety of morphologically and functionally
diverse cell types. It is not known how the intermingled cell types of an individual
adult brain region differ in their expressed genomes. Here we describe an atlas
of cell type transcriptomes in one brain region, the mouse retina. We found that
each adult cell type expressed a specific set of genes, including a unique set
of transcription factors, forming a 'barcode' for cell identity. Cell type transcriptomes
carried enough information to categorize cells into morphological classes and
types. Several genes that were specifically expressed in particular retinal circuit
elements, such as inhibitory neuron types, are associated with eye diseases. The
resource described here allows gene expression to be compared across adult retinal
cell types, experimenting with specific transcription factors to differentiate
stem or somatic cells to retinal cell types, and predicting cellular targets of
newly discovered disease-associated genes.

text: Outer membrane protein F, a major component of the Escherichia coli outer
membrane, was crystallized for the first time in lipidic mesophase of monoolein
in novel space groups, P1 and H32. Due to ease of its purification and crystallization
OmpF can be used as a benchmark protein for establishing membrane protein crystallization
in meso, as a "membrane lyzozyme" The packing of porin trimers in the
crystals of space group H32 is similar to natural outer membranes, providing the
first high-resolution insight into the close to native packing of OmpF. Surprisingly,
interaction between trimers is mediated exclusively by lipids, without direct
protein-protein contacts. Multiple ordered lipids are observed and many of them
occupy identical positions independently of the space group, identifying preferential
interaction sites of lipid acyl chains. Presence of ordered aliphatic chains close
to a positively charged area on the porin surface suggests a position for a lipopolysaccharide
binding site on the surface of the major E. coli porins.

text: 'Complex I is a key enzyme of the respiratory chain in many organisms. This
multi-protein complex with an intricate evolutionary history originated from the
unification of prebuilt modules of hydrogenases and transporters. Using recently
determined crystallographic structures of complex I we reanalyzed evolutionarily
related complexes that couple oxidoreduction to trans-membrane ion translocation.
Our analysis points to the previously unnoticed structural homology of the electron
input module of formate dehydrogenlyases and subunit NuoG of complex I. We also
show that all related to complex I hydrogenases likely operate via a conformation
driven mechanism with structural changes generated in the conserved coupling site
located at the interface of subunits NuoB/D/H. The coupling apparently originated
once in evolutionary history, together with subunit NuoH joining hydrogenase and
transport modules. Analysis of quinone oxidoreduction properties and the structure
of complex I allows us to suggest a fully reversible coupling mechanism. Our model
predicts that: 1) proton access to the ketone groups of the bound quinone is rigorously
controlled by the protein, 2) the negative electric charge of the anionic ubiquinol
head group is a major driving force for conformational changes.'

In the living cell, proteins are able to organize space much larger than their dimensions. In return, changes of intracellular space can influence biochemical reactions, allowing cells to sense their size and shape. Despite the possibility to reconstitute protein self-organization with only a few purified components, we still lack knowledge of how geometrical boundaries affect spatiotemporal protein patterns. Following a minimal systems approach, we used purified proteins and photolithographically patterned membranes to study the influence of spatial confinement on the self-organization of the Min system, a spatial regulator of bacterial cytokinesis, in vitro. We found that the emerging protein pattern responds even to the lateral, two-dimensional geometry of the membrane such that, as in the three-dimensional cell, Min protein waves travel along the longest axis of the membrane patch. This shows that for spatial sensing the Min system does not need to be enclosed in a three-dimensional compartment. Using a computational model we quantitatively analyzed our experimental findings and identified persistent binding of MinE to the membrane as requirement for the Min system to sense geometry. Our results give insight into the interplay between geometrical confinement and biochemical patterns emerging from a nonlinear reaction-diffusion system.

text: Leakage resilient cryptography attempts to incorporate side-channel leakage
into the black-box security model and designs cryptographic schemes that are provably
secure within it. Informally, a scheme is leakage-resilient if it remains secure
even if an adversary learns a bounded amount of arbitrary information about the
schemes internal state. Unfortunately, most leakage resilient schemes are unnecessarily
complicated in order to achieve strong provable security guarantees. As advocated
by Yu et al. [CCS’10], this mostly is an artefact of the security proof and in
practice much simpler construction may already suffice to protect against realistic
side-channel attacks. In this paper, we show that indeed for simpler constructions
leakage-resilience can be obtained when we aim for relaxed security notions where
the leakage-functions and/or the inputs to the primitive are chosen non-adaptively.
For example, we show that a three round Feistel network instantiated with a leakage
resilient PRF yields a leakage resilient PRP if the inputs are chosen non-adaptively
(This complements the result of Dodis and Pietrzak [CRYPTO’10] who show that if
a adaptive queries are allowed, a superlogarithmic number of rounds is necessary.)
We also show that a minor variation of the classical GGM construction gives a
leakage resilient PRF if both, the leakage-function and the inputs, are chosen
non-adaptively.

text: "We propose a new authentication protocol that is provably secure based on
a ring variant of the learning parity with noise (LPN) problem. The protocol follows
the design principle of the LPN-based protocol from Eurocrypt’11 (Kiltz et al.),
and like it, is a two round protocol secure against active attacks. Moreover,
our protocol has small communication complexity and a very small footprint which
makes it applicable in scenarios that involve low-cost, resource-constrained devices.\r\n\r\nPerformance-wise,
our protocol is more efficient than previous LPN-based schemes, such as the many
variants of the Hopper-Blum (HB) protocol and the aforementioned protocol from
Eurocrypt’11. Our implementation results show that it is even comparable to the
standard challenge-and-response protocols based on the AES block-cipher. Our basic
protocol is roughly 20 times slower than AES, but with the advantage of having
10 times smaller code size. Furthermore, if a few hundred bytes of non-volatile
memory are available to allow the storage of some off-line pre-computations, then
the online phase of our protocols is only twice as slow as AES.\r\n"
acknowledgement: "Supported by the European Research Council / ERC Starting Grant
(259668- PSPC)\r\nWe would like to thank the anonymous referees of this confer-
ence and those of the ECRYPT Workshop on Lightweight Cryptography for very useful
comments, and in particular for the suggestion that the scheme is somewhat vulnerable
to a man-in-the-middle attack whenever an adversary observes two reader challenges
that are the same. We hope that the attack we described in Appendix A corresponds
to what the reviewer had in mind. We also thank Tanja Lange for pointing us to the
pa- per of [Kir11] and for discussions of some of her recent work. "

text: We show that diamagnetic particles can be remotely manipulated by a magnet
by the reversible adsorption of dual-responsive, light-switchable/superparamagnetic
nanoparticles down to their surface. Adsorption occurs upon exposure to UV light,
and can be reversed thermally or by ambient light. The dynamic self-assembly of
thin films of the dual-responsive nanoparticles induces attractive interactions
between diamagnetic particles. We demonstrate that catalytic amounts of the dual-responsive
nanoparticles are sufficient to magnetically guide and deliver the diamagnetic
particles to desired locations, where they can then be released by disassembling
the dynamic layers of superparamagnetic nanoparticles with visible light.
