text: Different distance metrics produce Voronoi diagrams with different properties.
It is a well-known that on the (real) 2D plane or even on any 3D plane, a Voronoi
diagram (VD) based on the Euclidean distance metric produces convex Voronoi regions.
In this paper, we first show that this metric produces a persistent VD on the
2D digital plane, as it comprises digitally convex Voronoi regions and hence correctly
approximates the corresponding VD on the 2D real plane. Next, we show that on
a 3D digital plane D, the Euclidean metric spanning over its voxel set does not
guarantee a digital VD which is persistent with the real-space VD. As a solution,
we introduce a novel concept of functional-plane-convexity, which is ensured by
the Euclidean metric spanning over the pedal set of D. Necessary proofs and some
visual result have been provided to adjudge the merit and usefulness of the proposed
concept.

text: Bell correlations, indicating nonlocality in composite quantum systems, were
until recently only seen in small systems. Here, we demonstrate Bell correlations
in squeezed states of 5×105 Rb87 atoms. The correlations are inferred using collective
measurements as witnesses and are statistically significant to 124 standard deviations.
The states are both generated and characterized using optical-cavity aided measurements.

text: Transcription initiation at the ribosomal RNA promoter requires RNA polymerase
(Pol) I and the initiation factors Rrn3 and core factor (CF). Here, we combine
X-ray crystallography and cryo-electron microscopy (cryo-EM) to obtain a molecular
model for basal Pol I initiation. The three-subunit CF binds upstream promoter
DNA, docks to the Pol I-Rrn3 complex, and loads DNA into the expanded active center
cleft of the polymerase. DNA unwinding between the Pol I protrusion and clamp
domains enables cleft contraction, resulting in an active Pol I conformation and
RNA synthesis. Comparison with the Pol II system suggests that promoter specificity
relies on a distinct “bendability” and “meltability” of the promoter sequence
that enables contacts between initiation factors, DNA, and polymerase.

text: 'The conserved polymerase-Associated factor 1 complex (Paf1C) plays multiple
roles in chromatin transcription and genomic regulation. Paf1C comprises the five
subunits Paf1, Leo1, Ctr9, Cdc73 and Rtf1, and binds to the RNA polymerase II
(Pol II) transcription elongation complex (EC). Here we report the reconstitution
of Paf1C from Saccharomyces cerevisiae, and a structural analysis of Paf1C bound
to a Pol II EC containing the elongation factor TFIIS. Cryo-electron microscopy
and crosslinking data reveal that Paf1C is highly mobile and extends over the
outer Pol II surface from the Rpb2 to the Rpb3 subunit. The Paf1-Leo1 heterodimer
and Cdc73 form opposite ends of Paf1C, whereas Ctr9 bridges between them. Consistent
with the structural observations, the initiation factor TFIIF impairs Paf1C binding
to Pol II, whereas the elongation factor TFIIS enhances it. We further show that
Paf1C is globally required for normal mRNA transcription in yeast. These results
provide a three-dimensional framework for further analysis of Paf1C function in
transcription through chromatin. '

text: The first hundred attoseconds of the electron dynamics during strong field
tunneling ionization are investigated. We quantify theoretically how the electron’s
classical trajectories in the continuum emerge from the tunneling process and
test the results with those achieved in parallel from attoclock measurements.
An especially high sensitivity on the tunneling barrier is accomplished here by
comparing the momentum distributions of two atomic species of slightly deviating
atomic potentials (argon and krypton) being ionized under absolutely identical
conditions with near-infrared laser pulses (1300 nm). The agreement between experiment
and theory provides clear evidence for a nonzero tunneling time delay and a nonvanishing
longitudinal momentum of the electron at the “tunnel exit.”

text: During transcription, RNA polymerase II (Pol II) associates with the conserved
elongation factor DSIF. DSIF renders the elongation complex stable and functions
during Pol II pausing and RNA processing. We combined cryo-EM and X-ray crystallography
to determine the structure of the mammalian Pol II-DSIF elongation complex at
a nominal resolution of 3.4. Human DSIF has a modular structure with two domains
forming a DNA clamp, two domains forming an RNA clamp, and one domain buttressing
the RNA clamp. The clamps maintain the transcription bubble, position upstream
DNA, and retain the RNA transcript in the exit tunnel. The mobile C-terminal region
of DSIF is located near exiting RNA, where it can recruit factors for RNA processing.
The structure provides insight into the roles of DSIF during mRNA synthesis.

text: In several settings of physics and chemistry one has to deal with molecules
interacting with some kind of an external environment, be it a gas, a solution,
or a crystal surface. Understanding molecular processes in the presence of such
a many-particle bath is inherently challenging, and usually requires large-scale
numerical computations. Here, we present an alternative approach to the problem,
based on the notion of the angulon quasiparticle. We show that molecules rotating
inside superfluid helium nanodroplets and Bose–Einstein condensates form angulons,
and therefore can be described by straightforward solutions of a simple microscopic
Hamiltonian. Casting the problem in the language of angulons allows us not only
to greatly simplify it, but also to gain insights into the origins of the observed
phenomena and to make predictions for future experimental studies.

text: 'Position based cryptography (PBC), proposed in the seminal work of Chandran,
Goyal, Moriarty, and Ostrovsky (SIAM J. Computing, 2014), aims at constructing
cryptographic schemes in which the identity of the user is his geographic position.
Chandran et al. construct PBC schemes for secure positioning and position-based
key agreement in the bounded-storage model (Maurer, J. Cryptology, 1992). Apart
from bounded memory, their security proofs need a strong additional restriction
on the power of the adversary: he cannot compute joint functions of his inputs.
Removing this assumption is left as an open problem. We show that an answer to
this question would resolve a long standing open problem in multiparty communication
complexity: finding a function that is hard to compute with low communication
complexity in the simultaneous message model, but easy to compute in the fully
adaptive model. On a more positive side: we also show some implications in the
other direction, i.e.: we prove that lower bounds on the communication complexity
of certain multiparty problems imply existence of PBC primitives. Using this result
we then show two attractive ways to “bypass” our hardness result: the first uses
the random oracle model, the second weakens the locality requirement in the bounded-storage
model to online computability. The random oracle construction is arguably one
of the simplest proposed so far in this area. Our results indicate that constructing
improved provably secure protocols for PBC requires a better understanding of
multiparty communication complexity. This is yet another example where negative
results in one area (in our case: lower bounds in multiparty communication complexity)
can be used to construct secure cryptographic schemes.'

text: Neutrophils or polymorphonuclear cells (PMN) eliminate bacteria via phagocytosis
and/or NETosis. Apartfrom these conventional roles, PMN also have immune-regulatory
functions. They can transdifferentiateand upregulate MHCII as well as ligands
for costimulatory receptors which enables them to behave asantigen presenting
cells (APC). The initial step for activating T-cells is the formation of an immunesynapse
between T-cells and antigen-presenting cells. However, the immune synapse that
develops atthe PMN/T-cell contact zone is as yet hardly investigated due to the
non-availability of methods foranalysis of large number of PMN interactions. In
order to overcome these obstacles, we introduce herea workflow to analyse the
immune synapse of primary human PMN and T-cells using multispectral imag-ing flow
cytometry (InFlow microscopy) and super-resolution microscopy. For that purpose,
we used CD3and CD66b as the lineage markers for T-cells and PMN, respectively.
Thereafter, we applied and criticallydiscussed various ‘‘masks” for identification
of T-cell PMN interactions. Using this approach, we foundthat a small fraction
of transdifferentiated PMN (CD66b+CD86high) formed stable PMN/T-cell conjugates.Interestingly,
while both CD3 and CD66b accumulation in the immune synapse was dependent on thematuration
state of the PMN, only CD3 accumulation was greatly enhanced by the presence of
superanti-gen. The actin cytoskeleton was weakly rearranged at the PMN side on
the immune synapse upon contactwith a T-cell in the presence of superantigen.
A more detailed analysis using super-resolution microscopy(structured-illumination
microscopy, SIM) confirmed this finding. Together, we present an InFlow micro-scopy
based approach for the large scale analysis of PMN/T-cell interactions and – combined
with SIM – apossibility for an in-depth analysis of protein translocation at the
site of interactions.

text: Several cryptographic schemes and applications are based on functions that
are both reasonably efficient to compute and moderately hard to invert, including
client puzzles for Denial-of-Service protection, password protection via salted
hashes, or recent proof-of-work blockchain systems. Despite their wide use, a
definition of this concept has not yet been distilled and formalized explicitly.
Instead, either the applications are proven directly based on the assumptions
underlying the function, or some property of the function is proven, but the security
of the application is argued only informally. The goal of this work is to provide
a (universal) definition that decouples the efforts of designing new moderately
hard functions and of building protocols based on them, serving as an interface
between the two. On a technical level, beyond the mentioned definitions, we instantiate
the model for four different notions of hardness. We extend the work of Alwen
and Serbinenko (STOC 2015) by providing a general tool for proving security for
the first notion of memory-hard functions that allows for provably secure applications.
The tool allows us to recover all of the graph-theoretic techniques developed
for proving security under the older, non-composable, notion of security used
by Alwen and Serbinenko. As an application of our definition of moderately hard
functions, we prove the security of two different schemes for proofs of effort
(PoE). We also formalize and instantiate the concept of a non-interactive proof
of effort (niPoE), in which the proof is not bound to a particular communication
context but rather any bit-string chosen by the prover.

text: 'The fact that the complete graph K5 does not embed in the plane has been
generalized in two independent directions. On the one hand, the solution of the
classical Heawood problem for graphs on surfaces established that the complete
graph Kn embeds in a closed surface M (other than the Klein bottle) if and only
if (n−3)(n−4) ≤ 6b1(M), where b1(M) is the first Z2-Betti number of M. On the
other hand, van Kampen and Flores proved that the k-skeleton of the n-dimensional
simplex (the higher-dimensional analogue of Kn+1) embeds in R2k if and only if
n ≤ 2k + 1. Two decades ago, Kühnel conjectured that the k-skeleton of the n-simplex
embeds in a compact, (k − 1)-connected 2k-manifold with kth Z2-Betti number bk
only if the following generalized Heawood inequality holds: (k+1 n−k−1) ≤ (k+1
2k+1)bk. This is a common generalization of the case of graphs on surfaces as
well as the van Kampen–Flores theorem. In the spirit of Kühnel’s conjecture, we
prove that if the k-skeleton of the n-simplex embeds in a compact 2k-manifold
with kth Z2-Betti number bk, then n ≤ 2bk(k 2k+2)+2k+4. This bound is weaker than
the generalized Heawood inequality, but does not require the assumption that M
is (k−1)-connected. Our results generalize to maps without q-covered points, in
the spirit of Tverberg’s theorem, for q a prime power. Our proof uses a result
of Volovikov about maps that satisfy a certain homological triviality condition.'

text: Small RNAs (sRNAs) regulate genes in plants and animals. Here, we show that
population-wide differences in color patterns in snapdragon flowers are caused
by an inverted duplication that generates sRNAs. The complexity and size of the
transcripts indicate that the duplication represents an intermediate on the pathway
to microRNA evolution. The sRNAs repress a pigment biosynthesis gene, creating
a yellow highlight at the site of pollinator entry. The inverted duplication exhibits
steep clines in allele frequency in a natural hybrid zone, showing that the allele
is under selection. Thus, regulatory interactions of evolutionarily recent sRNAs
can be acted upon by selection and contribute to the evolution of phenotypic diversity.

text: Animals adjust their behavioral priorities according to momentary needs and
prior experience. We show that Caenorhabditis elegans changes how it processes
sensory information according to the oxygen environment it experienced recently.
C. elegans acclimated to 7% O2 are aroused by CO2 and repelled by pheromones that
attract animals acclimated to 21% O2. This behavioral plasticity arises from prolonged
activity differences in a circuit that continuously signals O2 levels. A sustained
change in the activity of O2-sensing neurons reprograms the properties of their
postsynaptic partners, the RMG hub interneurons. RMG is gap-junctionally coupled
to the ASK and ADL pheromone sensors that respectively drive pheromone attraction
and repulsion. Prior O2 experience has opposite effects on the pheromone responsiveness
of these neurons. These circuit changes provide a physiological correlate of altered
pheromone valence. Our results suggest C. elegans stores a memory of recent O2
experience in the RMG circuit and illustrate how a circuit is flexibly sculpted
to guide behavioral decisions in a context-dependent manner.

text: 'Interleukin-17 (IL-17) is a major pro-inflammatory cytokine: it mediates
responses to pathogens or tissue damage, and drives autoimmune diseases. Little
is known about its role in the nervous system. Here we show that IL-17 has neuromodulator-like
properties in Caenorhabditis elegans. IL-17 can act directly on neurons to alter
their response properties and contribution to behaviour. Using unbiased genetic
screens, we delineate an IL-17 signalling pathway and show that it acts in the
RMG hub interneurons. Disrupting IL-17 signalling reduces RMG responsiveness to
input from oxygen sensors, and renders sustained escape from 21% oxygen transient
and contingent on additional stimuli. Over-activating IL-17 receptors abnormally
heightens responses to 21% oxygen in RMG neurons and whole animals. IL-17 deficiency
can be bypassed by optogenetic stimulation of RMG. Inducing IL-17 expression in
adults can rescue mutant defects within 6 h. These findings reveal a non-immunological
role of IL-17 modulating circuit function and behaviour.'

text: 'Bacteria in groups vary individually, and interact with other bacteria and
the environment to produce population-level patterns of gene expression. Investigating
such behavior in detail requires measuring and controlling populations at the
single-cell level alongside precisely specified interactions and environmental
characteristics. Here we present an automated, programmable platform that combines
image-based gene expression and growth measurements with on-line optogenetic expression
control for hundreds of individual Escherichia coli cells over days, in a dynamically
adjustable environment. This integrated platform broadly enables experiments that
bridge individual and population behaviors. We demonstrate: (i) population structuring
by independent closed-loop control of gene expression in many individual cells,
(ii) cell-cell variation control during antibiotic perturbation, (iii) hybrid
bio-digital circuits in single cells, and freely specifiable digital communication
between individual bacteria. These examples showcase the potential for real-time
integration of theoretical models with measurement and control of many individual
cells to investigate and engineer microbial population behavior.'

text: 'Moths and butterflies (Lepidoptera) usually have a pair of differentiated
WZ sex chromosomes. However, in most lineages outside of the division Ditrysia,
as well as in the sister order Trichoptera, females lack a W chromosome. The W
is therefore thought to have been acquired secondarily. Here we compare the genomes
of three Lepidoptera species (one Dytrisia and two non-Dytrisia) to test three
models accounting for the origin of the W: (1) a Z-autosome fusion; (2) a sex
chromosome turnover; and (3) a non-canonical mechanism (e.g., through the recruitment
of a B chromosome). We show that the gene content of the Z is highly conserved
across Lepidoptera (rejecting a sex chromosome turnover) and that very few genes
moved onto the Z in the common ancestor of the Ditrysia (arguing against a Z-autosome
fusion). Our comparative genomics analysis therefore supports the secondary acquisition
of the Lepidoptera W by a non-canonical mechanism, and it confirms the extreme
stability of well-differentiated sex chromosomes.'

text: We show that the Dyson Brownian Motion exhibits local universality after a
very short time assuming that local rigidity and level repulsion of the eigenvalues
hold. These conditions are verified, hence bulk spectral universality is proven,
for a large class of Wigner-like matrices, including deformed Wigner ensembles
and ensembles with non-stochastic variance matrices whose limiting densities differ
from Wigner's semicircle law.

text: 'Background: Increasing temperatures are predicted to strongly impact host-parasite
interactions, but empirical tests are rare. Host species that are naturally exposed
to a broad temperature spectrum offer the possibility to investigate the effects
of elevated temperatures on hosts and parasites. Using three-spined sticklebacks,
Gasterosteus aculeatus L., and tapeworms, Schistocephalus solidus (Müller, 1776),
originating from a cold and a warm water site of a volcanic lake, we subjected
sympatric and allopatric host-parasite combinations to cold and warm conditions
in a fully crossed design. We predicted that warm temperatures would promote the
development of the parasites, while the hosts might benefit from cooler temperatures.
We further expected adaptations to the local temperature and mutual adaptations
of local host-parasite pairs. Results: Overall, S. solidus parasites grew faster
at warm temperatures and stickleback hosts at cold temperatures. On a finer scale,
we observed that parasites were able to exploit their hosts more efficiently at
the parasite’s temperature of origin. In contrast, host tolerance towards parasite
infection was higher when sticklebacks were infected with parasites at the parasite’s
‘foreign’ temperature. Cold-origin sticklebacks tended to grow faster and parasite
infection induced a stronger immune response. Conclusions: Our results suggest
that increasing environmental temperatures promote the parasite rather than the
host and that host tolerance is dependent on the interaction between parasite
infection and temperature. Sticklebacks might use tolerance mechanisms towards
parasite infection in combination with their high plasticity towards temperature
changes to cope with increasing parasite infection pressures and rising temperatures.'

text: PMAC is a simple and parallel block-cipher mode of operation, which was introduced
by Black and Rogaway at Eurocrypt 2002. If instantiated with a (pseudo)random
permutation over n-bit strings, PMAC constitutes a provably secure variable input-length
(pseudo)random function. For adversaries making q queries, each of length at most
l (in n-bit blocks), and of total length σ ≤ ql, the original paper proves an
upper bound on the distinguishing advantage of Ο(σ2/2n), while the currently
best bound is Ο (qσ/2n).In this work we show that this bound is tight by giving
an attack with advantage Ω (q2l/2n). In the PMAC construction one initially XORs
a mask to every message block, where the mask for the ith block is computed as
τi := γi·L, where L is a (secret) random value, and γi is the i-th codeword of
the Gray code. Our attack applies more generally to any sequence of γi’s which
contains a large coset of a subgroup of GF(2n). We then investigate if the security
of PMAC can be further improved by using τi’s that are k-wise independent, for
k > 1 (the original distribution is only 1-wise independent). We observe that
the security of PMAC will not increase in general, even if the masks are chosen
from a 2-wise independent distribution, and then prove that the security increases
to O(q<2/2n), if the τi are 4-wise independent. Due to simple extension attacks,
this is the best bound one can hope for, using any distribution on the masks.
Whether 3-wise independence is already sufficient to get this level of security
is left as an open problem.
