text: 'Gene expression is regulated by the set of transcription factors (TFs) that
bind to the promoter. The ensuing regulating function is often represented as
a combinational logic circuit, where output (gene expression) is determined by
current input values (promoter bound TFs) only. However, the simultaneous arrival
of TFs is a strong assumption, since transcription and translation of genes introduce
intrinsic time delays and there is no global synchronisation among the arrival
times of different molecular species at their targets. We present an experimentally
implementable genetic circuit with two inputs and one output, which in the presence
of small delays in input arrival, exhibits qualitatively distinct population-level
phenotypes, over timescales that are longer than typical cell doubling times.
From a dynamical systems point of view, these phenotypes represent long-lived
transients: although they converge to the same value eventually, they do so after
a very long time span. The key feature of this toy model genetic circuit is that,
despite having only two inputs and one output, it is regulated by twenty-three
distinct DNA-TF configurations, two of which are more stable than others (DNA
looped states), one promoting and another blocking the expression of the output
gene. Small delays in input arrival time result in a majority of cells in the
population quickly reaching the stable state associated with the first input,
while exiting of this stable state occurs at a slow timescale. In order to mechanistically
model the behaviour of this genetic circuit, we used a rule-based modelling language,
and implemented a grid-search to find parameter combinations giving rise to long-lived
transients. Our analysis shows that in the absence of feedback, there exist path-dependent
gene regulatory mechanisms based on the long timescale of transients. The behaviour
of this toy model circuit suggests that gene regulatory networks can exploit event
timing to create phenotypes, and it opens the possibility that they could use
event timing to memorise events, without regulatory feedback. The model reveals
the importance of (i) mechanistically modelling the transitions between the different
DNA-TF states, and (ii) employing transient analysis thereof.'

text: Tropisms, growth responses to environmental stimuli such as light or gravity,
are spectacular examples of adaptive plant development. The plant hormone auxin
serves as a major coordinative signal. The PIN auxin exporters, through their
dynamic polar subcellular localizations, redirect auxin fluxes in response to
environmental stimuli and the resulting auxin gradients across organs underly
differential cell elongation and bending. In this review, we discuss recent advances
concerning regulations of PIN polarity during tropisms, focusing on PIN phosphorylation
and trafficking. We also cover how environmental cues regulate PIN actions during
tropisms, and a crucial role of auxin feedback on PIN polarity during bending
termination. Finally, the interactions between different tropisms are reviewed
to understand plant adaptive growth in the natural environment.

text: To overcome nitrogen deficiency, legume roots establish symbiotic interactions
with nitrogen-fixing rhizobia that is fostered in specialized organs (nodules).
Similar to other organs, nodule formation is determined by a local maximum of
the phytohormone auxin at the primordium site. However, how auxin regulates nodule
development remains poorly understood. Here, we found that in soybean, (Glycine
max), dynamic auxin transport driven by PIN-FORMED (PIN) transporter GmPIN1 is
involved in nodule primordium formation. GmPIN1 was specifically expressed in
nodule primordium cells and GmPIN1 was polarly localized in these cells. Two nodulation
regulators, (iso)flavonoids trigger expanded distribution of GmPIN1b to root cortical
cells, and cytokinin rearranges GmPIN1b polarity. Gmpin1abc triple mutants generated
with CRISPR-Cas9 showed impaired establishment of auxin maxima in nodule meristems
and aberrant divisions in the nodule primordium cells. Moreover, overexpression
of GmPIN1 suppressed nodule primordium initiation. GmPIN9d, an ortholog of Arabidopsis
thaliana PIN2, acts together with GmPIN1 later in nodule development to acropetally
transport auxin in vascular bundles, fine-tuning the auxin supply for nodule enlargement.
Our findings reveal how PIN-dependent auxin transport modulates different aspects
of soybean nodule development and suggest that establishment of auxin gradient
is a prerequisite for the proper interaction between legumes and rhizobia.

text: The set of known stable phases of water may not be complete, and some of the
phase boundaries between them are fuzzy. Starting from liquid water and a comprehensive
set of 50 ice structures, we compute the phase diagram at three hybrid density-functional-theory
levels of approximation, accounting for thermal and nuclear fluctuations as well
as proton disorder. Such calculations are only made tractable because we combine
machine-learning methods and advanced free-energy techniques. The computed phase
diagram is in qualitative agreement with experiment, particularly at pressures ≲ 8000
bar, and the discrepancy in chemical potential is comparable with the subtle uncertainties
introduced by proton disorder and the spread between the three hybrid functionals.
None of the hypothetical ice phases considered is thermodynamically stable in
our calculations, suggesting the completeness of the experimental water phase
diagram in the region considered. Our work demonstrates the feasibility of predicting
the phase diagram of a polymorphic system from first principles and provides a
thermodynamic way of testing the limits of quantum-mechanical calculations.

text: The relative motion of three impenetrable particles on a ring, in our case
two identical fermions and one impurity, is isomorphic to a triangular quantum
billiard. Depending on the ratio κ of the impurity and fermion masses, the billiards
can be integrable or non-integrable (also referred to in the main text as chaotic).
To set the stage, we first investigate the energy level distributions of the billiards
as a function of 1/κ ∈ [0, 1] and find no evidence of integrable cases beyond
the limiting values 1/κ = 1 and 1/κ = 0. Then, we use machine learning tools to
analyze properties of probability distributions of individual quantum states.
We find that convolutional neural networks can correctly classify integrable and
non-integrable states. The decisive features of the wave functions are the normalization
and a large number of zero elements, corresponding to the existence of a nodal
line. The network achieves typical accuracies of 97%, suggesting that machine
learning tools can be used to analyze and classify the morphology of probability
densities obtained in theory or experiment.

text: Most water in the universe may be superionic, and its thermodynamic and transport
properties are crucial for planetary science but difficult to probe experimentally
or theoretically. We use machine learning and free energy methods to overcome
the limitations of quantum mechanical simulations, and characterize hydrogen diffusion,
superionic transitions, and phase behaviors of water at extreme conditions. We
predict that a close-packed superionic phase with mixed stacking is stable over
a wide temperature and pressure range, while a body-centered cubic phase is only
thermodynamically stable in a small window but is kinetically favored. Our phase
boundaries, which are consistent with the existing-albeit scarce-experimental
observations, help resolve the fractions of insulating ice, different superionic
phases, and liquid water inside of ice giants.

text: Machine learning models are poised to make a transformative impact on chemical
sciences by dramatically accelerating computational algorithms and amplifying
insights available from computational chemistry methods. However, achieving this
requires a confluence and coaction of expertise in computer science and physical
sciences. This review is written for new and experienced researchers working at
the intersection of both fields. We first provide concise tutorials of computational
chemistry and machine learning methods, showing how insights involving both can
be achieved. We then follow with a critical review of noteworthy applications
that demonstrate how computational chemistry and machine learning can be used
together to provide insightful (and useful) predictions in molecular and materials
modeling, retrosyntheses, catalysis, and drug design.

text: Evolutionary adaptation is a major source of antibiotic resistance in bacterial
pathogens. Evolution-informed therapy aims to constrain resistance by accounting
for bacterial evolvability. Sequential treatments with antibiotics that target
different bacterial processes were previously shown to limit adaptation through
genetic resistance trade-offs and negative hysteresis. Treatment with homogeneous
sets of antibiotics is generally viewed to be disadvantageous, as it should rapidly
lead to cross-resistance. We here challenged this assumption by determining the
evolutionary response of Pseudomonas aeruginosa to experimental sequential treatments
involving both heterogenous and homogeneous antibiotic sets. To our surprise,
we found that fast switching between only β-lactam antibiotics resulted in increased
extinction of bacterial populations. We demonstrate that extinction is favored
by low rates of spontaneous resistance emergence and low levels of spontaneous
cross-resistance among the antibiotics in sequence. The uncovered principles may
help to guide the optimized use of available antibiotics in highly potent, evolution-informed
treatment designs.

text: 'The important roles of mitochondrial function and dysfunction in the process
of neurodegeneration are widely acknowledged. Retinal ganglion cells (RGCs) appear
to be a highly vulnerable neuronal cell type in the central nervous system with
respect to mitochondrial dysfunction but the actual reasons for this are still
incompletely understood. These cells have a unique circumstance where unmyelinated
axons must bend nearly 90° to exit the eye and then cross a translaminar pressure
gradient before becoming myelinated in the optic nerve. This region, the optic
nerve head, contains some of the highest density of mitochondria present in these
cells. Glaucoma represents a perfect storm of events occurring at this location,
with a combination of changes in the translaminar pressure gradient and reassignment
of the metabolic support functions of supporting glia, which appears to apply
increased metabolic stress to the RGC axons leading to a failure of axonal transport
mechanisms. However, RGCs themselves are also extremely sensitive to genetic mutations,
particularly in genes affecting mitochondrial dynamics and mitochondrial clearance.
These mutations, which systemically affect the mitochondria in every cell, often
lead to an optic neuropathy as the sole pathologic defect in affected patients.
This review summarizes knowledge of mitochondrial structure and function, the
known energy demands of neurons in general, and places these in the context of
normal and pathological characteristics of mitochondria attributed to RGCs. '

text: A few years ago, flow equations were introduced as a technique for calculating
the ground-state energies of cold Bose gases with and without impurities. In this
paper, we extend this approach to compute observables other than the energy. As
an example, we calculate the densities, and phase fluctuations of one-dimensional
Bose gases with one and two impurities. For a single mobile impurity, we use flow
equations to validate the mean-field results obtained upon the Lee-Low-Pines transformation.
We show that the mean-field approximation is accurate for all values of the boson-impurity
interaction strength as long as the phase coherence length is much larger than
the healing length of the condensate. For two static impurities, we calculate
impurity-impurity interactions induced by the Bose gas. We find that leading order
perturbation theory fails when boson-impurity interactions are stronger than boson-boson
interactions. The mean-field approximation reproduces the flow equation results
for all values of the boson-impurity interaction strength as long as boson-boson
interactions are weak.

text: We study an effective one-dimensional quantum model that includes friction
and spin-orbit coupling (SOC), and show that the model exhibits spin polarization
when both terms are finite. Most important, strong spin polarization can be observed
even for moderate SOC, provided that the friction is strong. Our findings might
help to explain the pronounced effect of chirality on spin distribution and transport
in chiral molecules. In particular, our model implies static magnetic properties
of a chiral molecule, which lead to Shiba-like states when a molecule is placed
on a superconductor, in accordance with recent experimental data.

text: The hippocampal mossy fiber synapse is a key synapse of the trisynaptic circuit.
Post-tetanic potentiation (PTP) is the most powerful form of plasticity at this
synaptic connection. It is widely believed that mossy fiber PTP is an entirely
presynaptic phenomenon, implying that PTP induction is input-specific, and requires
neither activity of multiple inputs nor stimulation of postsynaptic neurons. To
directly test cooperativity and associativity, we made paired recordings between
single mossy fiber terminals and postsynaptic CA3 pyramidal neurons in rat brain
slices. By stimulating non-overlapping mossy fiber inputs converging onto single
CA3 neurons, we confirm that PTP is input-specific and non-cooperative. Unexpectedly,
mossy fiber PTP exhibits anti-associative induction properties. EPSCs show only
minimal PTP after combined pre- and postsynaptic high-frequency stimulation with
intact postsynaptic Ca2+ signaling, but marked PTP in the absence of postsynaptic
spiking and after suppression of postsynaptic Ca2+ signaling (10 mM EGTA). PTP
is largely recovered by inhibitors of voltage-gated R- and L-type Ca2+ channels,
group II mGluRs, and vacuolar-type H+-ATPase, suggesting the involvement of retrograde
vesicular glutamate signaling. Transsynaptic regulation of PTP extends the repertoire
of synaptic computations, implementing a brake on mossy fiber detonation and a
“smart teacher” function of hippocampal mossy fiber synapses.

text: We investigate the Fröhlich polaron model on a three-dimensional torus, and
give a proof of the second-order quantum corrections to its ground-state energy
in the strong-coupling limit. Compared to previous work in the confined case,
the translational symmetry (and its breaking in the Pekar approximation) makes
the analysis substantially more challenging.

text: We provide a definition of the effective mass for the classical polaron described
by the Landau-Pekar equations. It is based on a novel variational principle, minimizing
the energy functional over states with given (initial) velocity. The resulting
formula for the polaron's effective mass agrees with the prediction by Landau
and Pekar.

text: 'This paper establishes new connections between many-body quantum systems,
One-body Reduced Density Matrices Functional Theory (1RDMFT) and Optimal Transport
(OT), by interpreting the problem of computing the ground-state energy of a finite
dimensional composite quantum system at positive temperature as a non-commutative
entropy regularized Optimal Transport problem. We develop a new approach to fully
characterize the dual-primal solutions in such non-commutative setting. The mathematical
formalism is particularly relevant in quantum chemistry: numerical realizations
of the many-electron ground state energy can be computed via a non-commutative
version of Sinkhorn algorithm. Our approach allows to prove convergence and robustness
of this algorithm, which, to our best knowledge, were unknown even in the two
marginal case. Our methods are based on careful a priori estimates in the dual
problem, which we believe to be of independent interest. Finally, the above results
are extended in 1RDMFT setting, where bosonic or fermionic symmetry conditions
are enforced on the problem.'

text: The quantum bits (qubits) on which superconducting quantum computers are based
have energy scales corresponding to photons with GHz frequencies. The energy of
photons in the gigahertz domain is too low to allow transmission through the noisy
room-temperature environment, where the signal would be lost in thermal noise.
Optical photons, on the other hand, have much higher energies, and signals can
be detected using highly efficient single-photon detectors. Transduction from
microwave to optical frequencies is therefore a potential enabling technology
for quantum devices. However, in such a device the optical pump can be a source
of thermal noise and thus degrade the fidelity; the similarity of input microwave
state to the output optical state. In order to investigate the magnitude of this
effect we model the sub-Kelvin thermal behavior of an electro-optic transducer
based on a lithium niobate whispering gallery mode resonator. We find that there
is an optimum power level for a continuous pump, whilst pulsed operation of the
pump increases the fidelity of the conversion.

text: "Aims: Mass antigen testing programs have been challenged because of an alleged
insufficient specificity, leading to a large number of false positives. The objective
of this study is to derive a lower bound of the specificity of the SD Biosensor
Standard Q Ag-Test in large scale practical use.\r\nMethods: Based on county data
from the nationwide tests for SARS-CoV-2 in Slovakia between 31.10.–1.11. 2020
we calculate a lower confidence bound for the specificity. As positive test results
were not systematically verified by PCR tests, we base the lower bound on a worst
case assumption, assuming all positives to be false positives.\r\nResults: 3,625,332
persons from 79 counties were tested. The lowest positivity rate was observed
in the county of Rožňava where 100 out of 34307 (0.29%) tests were positive. This
implies a test specificity of at least 99.6% (97.5% one-sided lower confidence
bound, adjusted for multiplicity).\r\nConclusion: The obtained lower bound suggests
a higher specificity compared to earlier studies in spite of the underlying worst
case assumption and the application in a mass testing setting. The actual specificity
is expected to exceed 99.6% if the prevalence in the respective regions was non-negligible
at the time of testing. To our knowledge, this estimate constitutes the first
bound obtained from large scale practical use of an antigen test."

text: Triangle mesh-based simulations are able to produce satisfying animations
of knitted and woven cloth; however, they lack the rich geometric detail of yarn-level
simulations. Naive texturing approaches do not consider yarn-level physics, while
full yarn-level simulations may become prohibitively expensive for large garments.
We propose a method to animate yarn-level cloth geometry on top of an underlying
deforming mesh in a mechanics-aware fashion. Using triangle strains to interpolate
precomputed yarn geometry, we are able to reproduce effects such as knit loops
tightening under stretching. In combination with precomputed mesh animation or
real-time mesh simulation, our method is able to animate yarn-level cloth in real-time
at large scales.

text: Photorealistic editing of head portraits is a challenging task as humans are
very sensitive to inconsistencies in faces. We present an approach for high-quality
intuitive editing of the camera viewpoint and scene illumination (parameterised
with an environment map) in a portrait image. This requires our method to capture
and control the full reflectance field of the person in the image. Most editing
approaches rely on supervised learning using training data captured with setups
such as light and camera stages. Such datasets are expensive to acquire, not readily
available and do not capture all the rich variations of in-the-wild portrait images.
In addition, most supervised approaches only focus on relighting, and do not allow
camera viewpoint editing. Thus, they only capture and control a subset of the
reflectance field. Recently, portrait editing has been demonstrated by operating
in the generative model space of StyleGAN. While such approaches do not require
direct supervision, there is a significant loss of quality when compared to the
supervised approaches. In this paper, we present a method which learns from limited
supervised training data. The training images only include people in a fixed neutral
expression with eyes closed, without much hair or background variations. Each
person is captured under 150 one-light-at-a-time conditions and under 8 camera
poses. Instead of training directly in the image space, we design a supervised
problem which learns transformations in the latent space of StyleGAN. This combines
the best of supervised learning and generative adversarial modeling. We show that
the StyleGAN prior allows for generalisation to different expressions, hairstyles
and backgrounds. This produces high-quality photorealistic results for in-the-wild
images and significantly outperforms existing methods. Our approach can edit the
illumination and pose simultaneously, and runs at interactive rates.
