text: Meiotic crossover frequency varies within genomes, which influences genetic
diversity and adaptation. In turn, genetic variation within populations can act
to modify crossover frequency in cis and trans. To identify genetic variation
that controls meiotic crossover frequency, we screened Arabidopsis accessions
using fluorescent recombination reporters. We mapped a genetic modifier of crossover
frequency in Col × Bur populations of Arabidopsis to a premature stop codon within
TBP-ASSOCIATED FACTOR 4b (TAF4b), which encodes a subunit of the RNA polymerase
II general transcription factor TFIID. The Arabidopsis taf4b mutation is a rare
variant found in the British Isles, originating in South-West Ireland. Using genetics,
genomics, and immunocytology, we demonstrate a genome-wide decrease in taf4b crossovers,
with strongest reduction in the sub-telomeric regions. Using RNA sequencing (RNA-seq)
from purified meiocytes, we show that TAF4b expression is meiocyte enriched, whereas
its paralog TAF4 is broadly expressed. Consistent with the role of TFIID in promoting
gene expression, RNA-seq of wild-type and taf4b meiocytes identified widespread
transcriptional changes, including in genes that regulate the meiotic cell cycle
and recombination. Therefore, TAF4b duplication is associated with acquisition
of meiocyte-specific expression and promotion of germline transcription, which
act directly or indirectly to elevate crossovers. This identifies a novel mode
of meiotic recombination control via a general transcription factor.

text: Transposable elements (TEs), the movement of which can damage the genome,
are epigenetically silenced in eukaryotes. Intriguingly, TEs are activated in
the sperm companion cell – vegetative cell (VC) – of the flowering plant Arabidopsis
thaliana. However, the extent and mechanism of this activation are unknown. Here
we show that about 100 heterochromatic TEs are activated in VCs, mostly by DEMETER-catalyzed
DNA demethylation. We further demonstrate that DEMETER access to some of these
TEs is permitted by the natural depletion of linker histone H1 in VCs. Ectopically
expressed H1 suppresses TEs in VCs by reducing DNA demethylation and via a methylation-independent
mechanism. We demonstrate that H1 is required for heterochromatin condensation
in plant cells and show that H1 overexpression creates heterochromatic foci in
the VC progenitor cell. Taken together, our results demonstrate that the natural
depletion of H1 during male gametogenesis facilitates DEMETER-directed DNA demethylation,
heterochromatin relaxation, and TE activation.

text: Genetic incompatibilities contribute to reproductive isolation between many
diverging populations, but it is still unclear to what extent they play a role
if divergence happens with gene flow. In contact zones between the "Crab" and
"Wave" ecotypes of the snail Littorina saxatilis divergent selection forms strong
barriers to gene flow, while the role of postzygotic barriers due to selection
against hybrids remains unclear. High embryo abortion rates in this species could
indicate the presence of such barriers. Postzygotic barriers might include genetic
incompatibilities (e.g. Dobzhansky-Muller incompatibilities) but also maladaptation,
both expected to be most pronounced in contact zones. In addition, embryo abortion
might reflect physiological stress on females and embryos independent of any genetic
stress. We examined all embryos of >500 females sampled outside and inside
contact zones of three populations in Sweden. Females' clutch size ranged from
0 to 1011 embryos (mean 130±123) and abortion rates varied between 0 and100% (mean
12%). We described female genotypes by using a hybrid index based on hundreds
of SNPs differentiated between ecotypes with which we characterised female genotypes.
We also calculated female SNP heterozygosity and inversion karyotype. Clutch size
did not vary with female hybrid index and abortion rates were only weakly related
to hybrid index in two sites but not at all in a third site. No additional variation
in abortion rate was explained by female SNP heterozygosity, but increased female
inversion heterozygosity added slightly to increased abortion. Our results show
only weak and probably biologically insignificant postzygotic barriers contributing
to ecotype divergence and the high and variable abortion rates were marginally,
if at all, explained by hybrid index of females.

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: 'This report presents the results of a friendly competition for formal verification
of continuous and hybrid systems with linear continuous dynamics. The friendly
competition took place as part of the workshop Applied Verification for Continuous
and Hybrid Systems (ARCH) in 2019. In its third edition, seven tools have been
applied to solve six different benchmark problems in the category for linear continuous
dynamics (in alphabetical order): CORA, CORA/SX, HyDRA, Hylaa, JuliaReach, SpaceEx,
and XSpeed. This report is a snapshot of the current landscape of tools and the
types of benchmarks they are particularly suited for. Due to the diversity of
problems, we are not ranking tools, yet the presented results provide one of the
most complete assessments of tools for the safety verification of continuous and
hybrid systems with linear continuous dynamics up to this date.'

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: "Consider a distributed system with n processors out of which f can be Byzantine
faulty. In the\r\napproximate agreement task, each processor i receives an input
value xi and has to decide on an\r\noutput value yi such that\r\n1. the output
values are in the convex hull of the non-faulty processors’ input values,\r\n2.
the output values are within distance d of each other.\r\n\r\n\r\nClassically,
the values are assumed to be from an m-dimensional Euclidean space, where m ≥
1.\r\nIn this work, we study the task in a discrete setting, where input values
with some structure\r\nexpressible as a graph. Namely, the input values are vertices
of a finite graph G and the goal is to\r\noutput vertices that are within distance
d of each other in G, but still remain in the graph-induced\r\nconvex hull of
the input values. For d = 0, the task reduces to consensus and cannot be solved
with\r\na deterministic algorithm in an asynchronous system even with a single
crash fault. For any d ≥ 1,\r\nwe show that the task is solvable in asynchronous
systems when G is chordal and n > (ω + 1)f,\r\nwhere ω is the clique number of
G. In addition, we give the first Byzantine-tolerant algorithm for a\r\nvariant
of lattice agreement. For synchronous systems, we show tight resilience bounds
for the exact\r\nvariants of these and related tasks over a large class of combinatorial
structures."

all-pairs shortest paths problem in O(log²n / ε) rounds on unweighted undirected
graphs. With a small additional additive factor, this also applies for weighted
graphs. This is the first sub-polynomial constant-factor approximation for APSP
in this model.\r\n - A (1+ε)-approximation for multi-source shortest paths problem
from O(√n) sources in O(log² n / ε) rounds on weighted undirected graphs. This
is the first sub-polynomial algorithm obtaining this approximation for a set of
sources of polynomial size.\r\n\r\nOur main techniques are new distance tools
that are obtained via improved algorithms for sparse matrix multiplication, which
we leverage to construct efficient hopsets and shortest paths. Furthermore, our
techniques extend to additional distance problems for which we improve upon the
state-of-the-art, including diameter approximation, and an exact single-source
shortest paths algorithm for weighted undirected graphs in Õ(n^{1/6}) rounds."

text: "This paper investigates the power of preprocessing in the CONGEST model.
Schmid and Suomela (ACM HotSDN 2013) introduced the SUPPORTED CONGEST model to
study the application of distributed algorithms in Software-Defined Networks (SDNs).
In this paper, we show that a large class of lower bounds in the CONGEST model
still hold in the SUPPORTED model, highlighting the robustness of these bounds.
This also raises the question how much does\r\npreprocessing help in the CONGEST
model."

text: "A key challenge for community ecology is to understand to what extent observational
data can be used to infer the underlying community assembly processes. As different
processes can lead to similar or even identical patterns, statistical analyses
of non‐manipulative observational data never yield undisputable causal inference
on the underlying processes. Still, most empirical studies in community ecology
are based on observational data, and hence understanding under which circumstances
such data can shed light on assembly processes is a central concern for community
ecologists. We simulated a spatial agent‐based model that generates variation
in metacommunity dynamics across multiple axes, including the four classic metacommunity
paradigms as special cases. We further simulated a virtual ecologist who analysed
snapshot data sampled from the simulations using eighteen output metrics derived
from beta‐diversity and habitat variation indices, variation partitioning and
joint species distribution modelling. Our results indicated two main axes of variation
in the output metrics. The first axis of variation described whether the landscape
has patchy or continuous variation, and thus was essentially independent of the
properties of the species community. The second axis of variation related to the
level of predictability of the metacommunity. The most predictable communities
were niche‐based metacommunities inhabiting static landscapes with marked environmental
heterogeneity, such as metacommunities following the species sorting paradigm
or the mass effects paradigm. The most unpredictable communities were neutral‐based
metacommunities inhabiting dynamics landscapes with little spatial heterogeneity,
such as metacommunities following the neutral or patch sorting paradigms. The
output metrics from joint species distribution modelling yielded generally the
highest resolution to disentangle among the simulated scenarios. Yet, the different
types of statistical approaches utilized in this study carried complementary information,
and thus our results suggest that the most comprehensive evaluation of metacommunity
structure can be obtained by combining them.\r\n"

text: "We study the effect of a linear tunneling coupling between two-dimensional
systems, each separately\r\nexhibiting the topological Berezinskii-Kosterlitz-Thouless
(BKT) transition. In the uncoupled limit, there\r\nare two phases: one where the
one-body correlation functions are algebraically decaying and the other with\r\nexponential
decay. When the linear coupling is turned on, a third BKT-paired phase emerges,
in which one-body correlations are exponentially decaying, while two-body correlation
functions exhibit power-law\r\ndecay. We perform numerical simulations in the
paradigmatic case of two coupled XY models at finite\r\ntemperature, finding evidences
that for any finite value of the interlayer coupling, the BKT-paired phase is\r\npresent.
We provide a picture of the phase diagram using a renormalization group approach."

text: "Graph games and Markov decision processes (MDPs) are standard models in reactive
synthesis and verification of probabilistic systems with nondeterminism. The class
of \U0001D714 -regular winning conditions; e.g., safety, reachability, liveness,
parity conditions; provides a robust and expressive specification formalism for
properties that arise in analysis of reactive systems. The resolutions of nondeterminism
in games and MDPs are represented as strategies, and we consider succinct representation
of such strategies. The decision-tree data structure from machine learning retains
the flavor of decisions of strategies and allows entropy-based minimization to
obtain succinct trees. However, in contrast to traditional machine-learning problems
where small errors are allowed, for winning strategies in graph games and MDPs
no error is allowed, and the decision tree must represent the entire strategy.
In this work we propose decision trees with linear classifiers for representation
of strategies in graph games and MDPs. We have implemented strategy representation
using this data structure and we present experimental results for problems on
graph games and MDPs, which show that this new data structure presents a much
more efficient strategy representation as compared to standard decision trees."

text: Plants as sessile organisms are constantly under attack by herbivores, rough
environmental situations, or mechanical pressure. These challenges often lead
to the induction of wounds or destruction of already specified and developed tissues.
Additionally, wounding makes plants vulnerable to invasion by pathogens, which
is why wound signalling often triggers specific defence responses. To stay competitive
or, eventually, survive under these circumstances, plants need to regenerate efficiently,
which in rigid, tissue migration-incompatible plant tissues requires post-embryonic
patterning and organogenesis. Now, several studies used laser-assisted single
cell ablation in the Arabidopsis root tip as a minimal wounding proxy. Here, we
discuss their findings and put them into context of a broader spectrum of wound
signalling, pathogen responses and tissue as well as organ regeneration.

text: Lymph nodes are es s ential organs of the immune s ys tem where adaptive
immune responses originate, and consist of various leukocyte populations and a
stromal backbone. Fibroblastic reticular cells (FRCs) are the main stromal cells
and form a sponge-like extracellular matrix network, called conduits , which they thems
elves enwrap and contract. Lymph, containing s oluble antigens , arrive
in lymph nodes via afferent lymphatic vessels that connect to the s ubcaps
ular s inus and conduit network. According to the current paradigm, the conduit network dis
tributes afferent lymph through lymph nodes and thus provides acces
s for immune cells to lymph-borne antigens. An elas tic caps ule s urrounds the organ and confines the
immune cells and FRC network. Lymph nodes are completely packed with lymphocytes and lymphocyte numbers directly dictates the
size of the organ. Although lymphocytes cons tantly enter and leave the lymph node, its s
ize remains remarkedly s table under homeostatic conditions. It is only
partly known how the cellularity and s ize of the lymph node is regulated and how the lymph node is
able to swell in inflammation. The role of the FRC network in lymph node s
welling and trans fer of fluids are inves tigated in this thes is. Furthermore, we s
tudied what trafficking routes are us ed by cancer cells in lymph nodes to form distal
metastases.We examined the role of a mechanical feedback in regulation of lymph node
swelling. Using parallel plate compression and UV-las er cutting experiments we dis
s ected the mechanical force dynamics of the whole lymph node, and individually
for FRCs and the caps ule. Physical forces generated by packed lymphocytes directly affect the tens
ion on the FRC network and capsule, which increases its resistance to swelling. This implies a feedback mechanism between tis
s ue pres s ure and ability of lymphocytes to enter the organ. Following inflammation, the lymph node swells
∼10 fold in two weeks . Yet, what is the role for tens ion on the FRC network and caps
ule, and how are lymphocytes able to enter in conditions that resist
swelling remain open ques tions . We s how that tens ion on the FRC network is important
to limit the swelling rate of the organ so that the FRC network can grow in a coordinated fashion.
This is illustrated by interfering with FRC contractility, which leads to faster
swelling rates and a dis organized FRC network in the inflamed lymph node.
Growth of the FRC network in turn is expected to releas e tens ion on thes
e s tructures and lowers the res is tance to swelling, thereby allowing
more lymphocytes to enter the organ and drive more swelling. Halt of swelling
coincides with a thickening of the caps ule, which forms a thick res
is tant band around the organ and lowers tens ion on the FRC network to form
a new force equilibrium.The FRC and conduit network are further believed to be a privileged s
ite of s oluble information within the lymph node, although many details remain uns
olved. We s how by 3D ultra-recons truction that FRCs and antigen pres
enting cells cover the s urface of conduit s ys tem for more than 99%
and we dis cus s the implications for s oluble information exchangeat the conduit
level.Finally, there is an ongoing debate in the cancer field whether and how
cancer cells in lymph nodes s eed dis tal metas tas es . We s how that cancer cells infus
ed into the lymph node can utilize trafficking routes of immune cells and rapidly migrate to blood vessels.
Once in the blood circulation, these cells are able to form metastases in
distal tissues.

text: We study few-body bound states of charged particles subject to attractive
zero-range/short-range plus repulsive Coulomb interparticle forces. The characteristic
length scales of the system at zero energy are set by the Coulomb length scale
D and the Coulomb-modified effective range r eff. We study shallow bound states
of charged particles with D >> r eff and show that these systems obey universal
scaling laws different from neutral particles. An accurate description of these
states requires both the Coulomb-modified scattering length and the effective
range unless the Coulomb interaction is very weak (D -> ). Our findings are relevant
for bound states whose spatial extent is significantly larger than the range of
the attractive potential. These states enjoy universality – their character is
independent of the shape of the short-range potential.

text: "In many shear flows like pipe flow, plane Couette flow, plane Poiseuille
flow, etc. turbulence emerges subcritically. Here, when subjected to strong enough
perturbations, the flow becomes turbulent in spite of the laminar base flow being
linearly stable. The nature of this instability has puzzled the scientific community
for decades. At onset, turbulence appears in localized patches and flows are spatio-temporally
intermittent. In pipe flow the localized turbulent structures are referred to
as puffs and in planar flows like plane Couette and channel flow, patches arise
in the form of localized oblique bands. In this thesis, we study the onset of
turbulence in channel flow in direct numerical simulations from a dynamical system
theory perspective, as well as by performing experiments in a large aspect ratio
channel.\r\n\r\nThe aim of the experimental work is to determine the critical
Reynolds number where turbulence first becomes sustained. Recently, the onset
of turbulence has been described in analogy to absorbing state phase transition
(i.e. directed percolation). In particular, it has been shown that the critical
point can be estimated from the competition between spreading and decay processes.
Here, by performing experiments, we identify the mechanisms underlying turbulence
proliferation in channel flow and find the critical Reynolds number, above which
turbulence becomes sustained. Above the critical point, the continuous growth
at the tip of the stripes outweighs the stochastic shedding of turbulent patches
at the tail and the stripes expand. For growing stripes, the probability to decay
decreases while the probability of stripe splitting increases. Consequently, and
unlike for the puffs in pipe flow, neither of these two processes is time-independent
i.e. memoryless. Coupling between stripe expansion and creation of new stripes
via splitting leads to a significantly lower critical point ($Re_c=670+/-10$)
than most earlier studies suggest. \r\n\r\nWhile the above approach sheds light
on how turbulence first becomes sustained, it provides no insight into the origin
of the stripes themselves. In the numerical part of the thesis we investigate
how turbulent stripes form from invariant solutions of the Navier-Stokes equations.
The origin of these turbulent stripes can be identified by applying concepts from
the dynamical system theory. In doing so, we identify the exact coherent structures
underlying stripes and their bifurcations and how they give rise to the turbulent
attractor in phase space. We first report a family of localized nonlinear traveling
wave solutions of the Navier-Stokes equations in channel flow. These solutions
show structural similarities with turbulent stripes in experiments like obliqueness,
quasi-streamwise streaks and vortices, etc. A parametric study of these traveling
wave solution is performed, with parameters like Reynolds number, stripe tilt
angle and domain size, including the stability of the solutions. These solutions
emerge through saddle-node bifurcations and form a phase space skeleton for the
turbulent stripes observed in the experiments. The lower branches of these TW
solutions at different tilt angles undergo Hopf bifurcation and new solutions
branches of relative periodic orbits emerge. These RPO solutions do not belong
to the same family and therefore the routes to chaos for different angles are
different. \r\n\r\nIn shear flows, turbulence at onset is transient in nature.
\ Consequently,turbulence can not be tracked to lower Reynolds numbers, where
the dynamics may simplify. Before this happens, turbulence becomes short-lived
and laminarizes. In the last part of the thesis, we show that using numerical
simulations we can continue turbulent stripes in channel flow past the 'relaminarization
barrier' all the way to their origin. Here, turbulent stripe dynamics simplifies
and the fluctuations are no longer stochastic and the stripe settles down to a
relative periodic orbit. This relative periodic orbit originates from the aforementioned
traveling wave solutions. Starting from the relative periodic orbit, a small increase
in speed i.e. Reynolds number gives rise to chaos and the attractor dimension
sharply increases in contrast to the classical transition scenario where the instabilities
affect the flow globally and give rise to much more gradual route to turbulence."

text: 'We give fault-tolerant algorithms for establishing synchrony in distributed
systems in which each of thennodes has its own clock. Our algorithms operate in
a very strong fault model: we require self-stabilisation, i.e.,the initial state
of the system may be arbitrary, and there can be up to fJournal of the ACM. 2019;66(5). doi:10.1145/3339471
