text: 'Social insects (i.e., ants, termites and the social bees and wasps) protect
their colonies from disease using a combination of individual immunity and collectively
performed defenses, termed social immunity. The first line of social immune defense
is sanitary care, which is performed by colony members to protect their pathogen-exposed
nestmates from developing an infection. If sanitary care fails and an infection
becomes established, a second line of social immune defense is deployed to stop
disease transmission within the colony and to protect the valuable queens, which
together with the males are the reproductive individuals of the colony. Insect
colonies are separated into these reproductive individuals and the sterile worker
force, forming a superorganismal reproductive unit reminiscent of the differentiated
germline and soma in a multicellular organism. Ultimately, the social immune response
preserves the germline of the superorganism insect colony and increases overall
fitness of the colony in case of disease. '

text: 'Bending-active structures are able to efficiently produce complex curved
shapes starting from flat panels. The desired deformation of the panels derives
from the proper selection of their elastic properties. Optimized panels, called
FlexMaps, are designed such that, once they are bent and assembled, the resulting
static equilibrium configuration matches a desired input 3D shape. The FlexMaps
elastic properties are controlled by locally varying spiraling geometric mesostructures,
which are optimized in size and shape to match the global curvature (i.e., bending
requests) of the target shape. The design pipeline starts from a quad mesh representing
the input 3D shape, which defines the edge size and the total amount of spirals:
every quad will embed one spiral. Then, an optimization algorithm tunes the geometry
of the spirals by using a simplified pre-computed rod model. This rod model is
derived from a non-linear regression algorithm which approximates the non-linear
behavior of solid FEM spiral models subject to hundreds of load combinations.
This innovative pipeline has been applied to the project of a lightweight plywood
pavilion named FlexMaps Pavilion, which is a single-layer piecewise twisted arc
that fits a bounding box of 3.90x3.96x3.25 meters.'

text: We propose a new model for detecting visual relationships, such as "person
riding motorcycle" or "bottle on table". This task is an important step towards
comprehensive structured mage understanding, going beyond detecting individual
objects. Our main novelty is a Box Attention mechanism that allows to model pairwise
interactions between objects using standard object detection pipelines. The resulting
model is conceptually clean, expressive and relies on well-justified training
and prediction procedures. Moreover, unlike previously proposed approaches, our
model does not introduce any additional complex components or hyperparameters
on top of those already required by the underlying detection model. We conduct
an experimental evaluation on two datasets, V-COCO and Open Images, demonstrating
strong quantitative and qualitative results.

text: Deep neural networks (DNNs) have become increasingly important due to their
excellent empirical performance on a wide range of problems. However, regularization
is generally achieved by indirect means, largely due to the complex set of functions
defined by a network and the difficulty in measuring function complexity. There
exists no method in the literature for additive regularization based on a norm
of the function, as is classically considered in statistical learning theory.
In this work, we study the tractability of function norms for deep neural networks
with ReLU activations. We provide, to the best of our knowledge, the first proof
in the literature of the NP-hardness of computing function norms of DNNs of 3
or more layers. We also highlight a fundamental difference between shallow and
deep networks. In the light on these results, we propose a new regularization
strategy based on approximate function norms, and show its efficiency on a segmentation
task with a DNN.

text: We review the history of population genetics, starting with its origins a
century ago from the synthesis between Mendel and Darwin's ideas, through to the
recent development of sophisticated schemes of inference from sequence data, based
on the coalescent. We explain the close relation between the coalescent and a
diffusion process, which we illustrate by their application to understand spatial
structure. We summarise the powerful methods available for analysis of multiple
loci, when linkage equilibrium can be assumed, and then discuss approaches to
the more challenging case, where associations between alleles require that we
follow genotype, rather than allele, frequencies. Though we can hardly cover the
whole of population genetics, we give an overview of the current state of the
subject, and future challenges to it.

text: "Denote by ∆N the N-dimensional simplex. A map f : ∆N → Rd is an almost r-embedding
if fσ1∩. . .∩fσr = ∅ whenever σ1, . . . , σr are pairwise disjoint faces. A counterexample
to the topological Tverberg conjecture asserts that if r is not a prime power
and d ≥ 2r + 1, then there is an almost r-embedding ∆(d+1)(r−1) → Rd. This was
improved by Blagojevi´c–Frick–Ziegler using a simple construction of higher-dimensional
counterexamples by taking k-fold join power of lower-dimensional ones. We improve
this further (for d large compared to r): If r is not a prime power and N := (d+
1)r−r l\r\nd + 2 r + 1 m−2, then there is an almost r-embedding ∆N → Rd. For the
r-fold van Kampen–Flores conjecture we also produce counterexamples which are
stronger than previously known. Our proof is based on generalizations of the Mabillard–Wagner
theorem on construction of almost r-embeddings from equivariant maps, and of the
Ozaydin theorem on existence of equivariant maps. "

text: "A proxy re-encryption (PRE) scheme is a public-key encryption scheme that
allows the holder of a key pk to derive a re-encryption key for any other key
\U0001D45D\U0001D458′. This re-encryption key lets anyone transform ciphertexts
under pk into ciphertexts under \U0001D45D\U0001D458′ without having to know the
underlying message, while transformations from \U0001D45D\U0001D458′ to pk should
not be possible (unidirectional). Security is defined in a multi-user setting
against an adversary that gets the users’ public keys and can ask for re-encryption
keys and can corrupt users by requesting their secret keys. Any ciphertext that
the adversary cannot trivially decrypt given the obtained secret and re-encryption
keys should be secure.\r\n\r\nAll existing security proofs for PRE only show selective
security, where the adversary must first declare the users it wants to corrupt.
This can be lifted to more meaningful adaptive security by guessing the set of
corrupted users among the n users, which loses a factor exponential in Open image
in new window , rendering the result meaningless already for moderate Open image
in new window .\r\n\r\nJafargholi et al. (CRYPTO’17) proposed a framework that
in some cases allows to give adaptive security proofs for schemes which were previously
only known to be selectively secure, while avoiding the exponential loss that
results from guessing the adaptive choices made by an adversary. We apply their
framework to PREs that satisfy some natural additional properties. Concretely,
we give a more fine-grained reduction for several unidirectional PREs, proving
adaptive security at a much smaller loss. The loss depends on the graph of users
whose edges represent the re-encryption keys queried by the adversary. For trees
and chains the loss is quasi-polynomial in the size and for general graphs it
is exponential in their depth and indegree (instead of their size as for previous
reductions). Fortunately, trees and low-depth graphs cover many, if not most,
interesting applications.\r\n\r\nOur results apply e.g. to the bilinear-map based
PRE schemes by Ateniese et al. (NDSS’05 and CT-RSA’09), Gentry’s FHE-based scheme
(STOC’09) and the LWE-based scheme by Chandran et al. (PKC’14)."

text: Electron transport in two-dimensional conducting materials such as graphene,
with dominant electron–electron interaction, exhibits unusual vortex flow that
leads to a nonlocal current-field relation (negative resistance), distinct from
the classical Ohm’s law. The transport behavior of these materials is best described
by low Reynolds number hydrodynamics, where the constitutive pressure–speed relation
is Stoke’s law. Here we report evidence of such vortices observed in a viscous
flow of Newtonian fluid in a microfluidic device consisting of a rectangular cavity—analogous
to the electronic system. We extend our experimental observations to elliptic
cavities of different eccentricities, and validate them by numerically solving
bi-harmonic equation obtained for the viscous flow with no-slip boundary conditions.
We verify the existence of a predicted threshold at which vortices appear. Strikingly,
we find that a two-dimensional theoretical model captures the essential features
of three-dimensional Stokes flow in experiments.

text: Speed of sound waves in gases and liquids are governed by the compressibility
of the medium. There exists another type of non-dispersive wave where the wave
speed depends on stress instead of elasticity of the medium. A well-known example
is the Alfven wave, which propagates through plasma permeated by a magnetic field
with the speed determined by magnetic tension. An elastic analogue of Alfven waves
has been predicted in a flow of dilute polymer solution where the elastic stress
of the stretching polymers determines the elastic wave speed. Here we present
quantitative evidence of elastic Alfven waves in elastic turbulence of a viscoelastic
creeping flow between two obstacles in channel flow. The key finding in the experimental
proof is a nonlinear dependence of the elastic wave speed cel on the Weissenberg
number Wi, which deviates from predictions based on a model of linear polymer
elasticity.

text: Epidermal growth factor receptor (EGFR) signaling controls skin development
and homeostasis inmice and humans, and its deficiency causes severe skin inflammation,
which might affect epidermalstem cell behavior. Here, we describe the inflammation-independent
effects of EGFR deficiency dur-ing skin morphogenesis and in adult hair follicle
stem cells. Expression and alternative splicing analysisof RNA sequencing data
from interfollicular epidermis and outer root sheath indicate that EGFR con-trols
genes involved in epidermal differentiation and also in centrosome function, DNA
damage, cellcycle, and apoptosis. Genetic experiments employingp53deletion in
EGFR-deficient epidermis revealthat EGFR signaling exhibitsp53-dependent functions
in proliferative epidermal compartments, aswell asp53-independent functions in
differentiated hair shaft keratinocytes. Loss of EGFR leads toabsence of LEF1
protein specifically in the innermost epithelial hair layers, resulting in disorganizationof
medulla cells. Thus, our results uncover important spatial and temporal features
of cell-autonomousEGFR functions in the epidermis.
