text: We evaluate the usefulness of persistent homology in the analysis of heart
rate variability. In our approach we extract several topological descriptors characterising
datasets of RR-intervals, which are later used in classical machine learning algorithms.
By this method we are able to differentiate the group of patients with the history
of transient ischemic attack and the group of hypertensive patients.

text: Glioblastoma is the most malignant cancer in the brain and currently incurable.
It is urgent to identify effective targets for this lethal disease. Inhibition
of such targets should suppress the growth of cancer cells and, ideally also precancerous
cells for early prevention, but minimally affect their normal counterparts. Using
genetic mouse models with neural stem cells (NSCs) or oligodendrocyte precursor
cells (OPCs) as the cells‐of‐origin/mutation, it is shown that the susceptibility
of cells within the development hierarchy of glioma to the knockout of insulin‐like
growth factor I receptor (IGF1R) is determined not only by their oncogenic states,
but also by their cell identities/states. Knockout of IGF1R selectively disrupts
the growth of mutant and transformed, but not normal OPCs, or NSCs. The desirable
outcome of IGF1R knockout on cell growth requires the mutant cells to commit to
the OPC identity regardless of its development hierarchical status. At the molecular
level, oncogenic mutations reprogram the cellular network of OPCs and force them
to depend more on IGF1R for their growth. A new‐generation brain‐penetrable, orally
available IGF1R inhibitor harnessing tumor OPCs in the brain is also developed.
The findings reveal the cellular window of IGF1R targeting and establish IGF1R
as an effective target for the prevention and treatment of glioblastoma.

text: Aqueous iodine based electrochemical energy storage is considered a potential
candidate to improve sustainability and performance of current battery and supercapacitor
technology. It harnesses the redox activity of iodide, iodine, and polyiodide
species in the confined geometry of nanoporous carbon electrodes. However, current
descriptions of the electrochemical reaction mechanism to interconvert these species
are elusive. Here we show that electrochemical oxidation of iodide in nanoporous
carbons forms persistent solid iodine deposits. Confinement slows down dissolution
into triiodide and pentaiodide, responsible for otherwise significant self-discharge
via shuttling. The main tools for these insights are in situ Raman spectroscopy
and in situ small and wide-angle X-ray scattering (in situ SAXS/WAXS). In situ
Raman confirms the reversible formation of triiodide and pentaiodide. In situ
SAXS/WAXS indicates remarkable amounts of solid iodine deposited in the carbon
nanopores. Combined with stochastic modeling, in situ SAXS allows quantifying
the solid iodine volume fraction and visualizing the iodine structure on 3D lattice
models at the sub-nanometer scale. Based on the derived mechanism, we demonstrate
strategies for improved iodine pore filling capacity and prevention of self-discharge,
applicable to hybrid supercapacitors and batteries.

text: The parabigeminal nucleus (PBG) is the mammalian homologue to the isthmic
complex of other vertebrates. Optogenetic stimulation of the PBG induces freezing
and escape in mice, a result thought to be caused by a PBG projection to the central
nucleus of the amygdala. However, the isthmic complex, including the PBG, has
been classically considered satellite nuclei of the Superior Colliculus (SC),
which upon stimulation of its medial part also triggers fear and avoidance reactions.
As the PBG-SC connectivity is not well characterized, we investigated whether
the topology of the PBG projection to the SC could be related to the behavioral
consequences of PBG stimulation. To that end, we performed immunohistochemistry,
in situ hybridization and neural tracer injections in the SC and PBG in a diurnal
rodent, the Octodon degus. We found that all PBG neurons expressed both glutamatergic
and cholinergic markers and were distributed in clearly defined anterior (aPBG)
and posterior (pPBG) subdivisions. The pPBG is connected reciprocally and topographically
to the ipsilateral SC, whereas the aPBG receives afferent axons from the ipsilateral
SC and projected exclusively to the contralateral SC. This contralateral projection
forms a dense field of terminals that is restricted to the medial SC, in correspondence
with the SC representation of the aerial binocular field which, we also found,
in O. degus prompted escape reactions upon looming stimulation. Therefore, this
specialized topography allows binocular interactions in the SC region controlling
responses to aerial predators, suggesting a link between the mechanisms by which
the SC and PBG produce defensive behaviors.

text: 'Epistasis, the context-dependence of the contribution of an amino acid substitution
to fitness, is common in evolution. To detect epistasis, fitness must be measured
for at least four genotypes: the reference genotype, two different single mutants
and a double mutant with both of the single mutations. For higher-order epistasis
of the order n, fitness has to be measured for all 2n genotypes of an n-dimensional
hypercube in genotype space forming a ‘combinatorially complete dataset’. So far,
only a handful of such datasets have been produced by manual curation. Concurrently,
random mutagenesis experiments have produced measurements of fitness and other
phenotypes in a high-throughput manner, potentially containing a number of combinatorially
complete datasets. We present an effective recursive algorithm for finding all
hypercube structures in random mutagenesis experimental data. To test the algorithm,
we applied it to the data from a recent HIS3 protein dataset and found all 199
847 053 unique combinatorially complete genotype combinations of dimensionality
ranging from 2 to 12. The algorithm may be useful for researchers looking for
higher-order epistasis in their high-throughput experimental data.'

text: Error analysis and data visualization of positive COVID-19 cases in 27 countries
have been performed up to August 8, 2020. This survey generally observes a progression
from early exponential growth transitioning to an intermediate power-law growth
phase, as recently suggested by Ziff and Ziff. The occurrence of logistic growth
after the power-law phase with lockdowns or social distancing may be described
as an effect of avoidance. A visualization of the power-law growth exponent over
short time windows is qualitatively similar to the Bhatia visualization for pandemic
progression. Visualizations like these can indicate the onset of second waves
and may influence social policy.

text: 'Extrasynaptic actions of glutamate are limited by high-affinity transporters
expressed by perisynaptic astroglial processes (PAPs): this helps maintain point-to-point
transmission in excitatory circuits. Memory formation in the brain is associated
with synaptic remodeling, but how this affects PAPs and therefore extrasynaptic
glutamate actions is poorly understood. Here, we used advanced imaging methods,
in situ and in vivo, to find that a classical synaptic memory mechanism, long-term
potentiation (LTP), triggers withdrawal of PAPs from potentiated synapses. Optical
glutamate sensors combined with patch-clamp and 3D molecular localization reveal
that LTP induction thus prompts spatial retreat of astroglial glutamate transporters,
boosting glutamate spillover and NMDA-receptor-mediated inter-synaptic cross-talk.
The LTP-triggered PAP withdrawal involves NKCC1 transporters and the actin-controlling
protein cofilin but does not depend on major Ca2+-dependent cascades in astrocytes.
We have therefore uncovered a mechanism by which a memory trace at one synapse
could alter signal handling by multiple neighboring connections.'

text: Nature creates electrons with two values of the spin projection quantum number.
In certain applications, it is important to filter electrons with one spin projection
from the rest. Such filtering is not trivial, since spin-dependent interactions
are often weak, and cannot lead to any substantial effect. Here we propose an
efficient spin filter based upon scattering from a two-dimensional crystal, which
is made of aligned point magnets. The polarization of the outgoing electron flux
is controlled by the crystal, and reaches maximum at specific values of the parameters.
In our scheme, polarization increase is accompanied by higher reflectivity of
the crystal. High transmission is feasible in scattering from a quantum cavity
made of two crystals. Our findings can be used for studies of low-energy spin-dependent
scattering from two-dimensional ordered structures made of magnetic atoms or aligned
chiral molecules.

text: Pancreatic islets play an essential role in regulating blood glucose level.
Although the molecular pathways underlying islet cell differentiation are beginning
to be resolved, the cellular basis of islet morphogenesis and fate allocation
remain unclear. By combining unbiased and targeted lineage tracing, we address
the events leading to islet formation in the mouse. From the statistical analysis
of clones induced at multiple embryonic timepoints, here we show that, during
the secondary transition, islet formation involves the aggregation of multiple
equipotent endocrine progenitors that transition from a phase of stochastic amplification
by cell division into a phase of sublineage restriction and limited islet fission.
Together, these results explain quantitatively the heterogeneous size distribution
and degree of polyclonality of maturing islets, as well as dispersion of progenitors
within and between islets. Further, our results show that, during the secondary
transition, α- and β-cells are generated in a contemporary manner. Together, these
findings provide insight into the cellular basis of islet development.

text: Cell fate transitions are key to development and homeostasis. It is thus essential
to understand the cellular mechanisms controlling fate transitions. Cell division
has been implicated in fate decisions in many stem cell types, including neuronal
and epithelial progenitors. In other stem cells, such as embryonic stem (ES) cells,
the role of division remains unclear. Here, we show that exit from naive pluripotency
in mouse ES cells generally occurs after a division. We further show that exit
timing is strongly correlated between sister cells, which remain connected by
cytoplasmic bridges long after division, and that bridge abscission progressively
accelerates as cells exit naive pluripotency. Finally, interfering with abscission
impairs naive pluripotency exit, and artificially inducing abscission accelerates
it. Altogether, our data indicate that a switch in the division machinery leading
to faster abscission regulates pluripotency exit. Our study identifies abscission
as a key cellular process coupling cell division to fate transitions.
