text: Recent studies suggest that unstable, nonchaotic solutions of the Navier-Stokes
equation may provide deep insights into fluid turbulence. In this article, we
present a combined experimental and numerical study exploring the dynamical role
of unstable equilibrium solutions and their invariant manifolds in a weakly turbulent,
electromagnetically driven, shallow fluid layer. Identifying instants when turbulent
evolution slows down, we compute 31 unstable equilibria of a realistic two-dimensional
model of the flow. We establish the dynamical relevance of these unstable equilibria
by showing that they are closely visited by the turbulent flow. We also establish
the dynamical relevance of unstable manifolds by verifying that they are shadowed
by turbulent trajectories departing from the neighborhoods of unstable equilibria
over large distances in state space.

text: "Background: Transport protein particle (TRAPP) is a multisubunit complex
that regulates membrane trafficking through the Golgi apparatus. The clinical
phenotype associated with mutations in various TRAPP subunits has allowed elucidation
of their functions in specific tissues. The role of some subunits in human disease,
however, has not been fully established, and their functions remain uncertain.\r\n\r\nObjective:
We aimed to expand the range of neurodevelopmental disorders associated with mutations
in TRAPP subunits by exome sequencing of consanguineous families.\r\n\r\nMethods:
Linkage and homozygosity mapping and candidate gene analysis were used to identify
homozygous mutations in families. Patient fibroblasts were used to study splicing
defect and zebrafish to model the disease.\r\n\r\nResults: We identified six individuals
from three unrelated families with a founder homozygous splice mutation in TRAPPC6B,
encoding a core subunit of the complex TRAPP I. Patients manifested a neurodevelopmental
disorder characterised by microcephaly, epilepsy and autistic features, and showed
splicing defect. Zebrafish trappc6b morphants replicated the human phenotype,
displaying decreased head size and neuronal hyperexcitability, leading to a lower
seizure threshold.\r\n\r\nConclusion: This study provides clinical and functional
evidence of the role of TRAPPC6B in brain development and function."

text: "Borel probability measures living on metric spaces are fundamental\r\nmathematical
objects. There are several meaningful distance functions that make the collection
of the probability measures living on a certain space a metric space. We are interested
in the description of the structure of the isometries of such metric spaces. We
overview some of the recent results of the topic and we also provide some new
ones concerning the Wasserstein distance. More specifically, we consider the space
of all Borel probability measures on the unit sphere of a Euclidean space endowed
with the Wasserstein metric W_p for arbitrary p >= 1, and we show that the
action of a Wasserstein isometry on the set of Dirac measures is induced by an
isometry of the underlying unit sphere."

text: In this paper we define and study the classical Uniform Electron Gas (UEG),
a system of infinitely many electrons whose density is constant everywhere in
space. The UEG is defined differently from Jellium, which has a positive constant
background but no constraint on the density. We prove that the UEG arises in Density
Functional Theory in the limit of a slowly varying density, minimizing the indirect
Coulomb energy. We also construct the quantum UEG and compare it to the classical
UEG at low density.

text: For ultrafast fixation of biological samples to avoid artifacts, high-pressure
freezing (HPF) followed by freeze substitution (FS) is preferred over chemical
fixation at room temperature. After HPF, samples are maintained at low temperature
during dehydration and fixation, while avoiding damaging recrystallization. This
is a notoriously slow process. McDonald and Webb demonstrated, in 2011, that sample
agitation during FS dramatically reduces the necessary time. Then, in 2015, we
(H.G. and S.R.) introduced an agitation module into the cryochamber of an automated
FS unit and demonstrated that the preparation of algae could be shortened from
days to a couple of hours. We argued that variability in the processing, reproducibility,
and safety issues are better addressed using automated FS units. For dissemination,
we started low-cost manufacturing of agitation modules for two of the most widely
used FS units, the Automatic Freeze Substitution Systems, AFS(1) and AFS2, from
Leica Microsystems, using three dimensional (3D)-printing of the major components.
To test them, several labs independently used the modules on a wide variety of
specimens that had previously been processed by manual agitation, or without agitation.
We demonstrate that automated processing with sample agitation saves time, increases
flexibility with respect to sample requirements and protocols, and produces data
of at least as good quality as other approaches.
