text: AbstractLow socio-economic status is associated
with higher SARS-CoV-2 incidences. In this paper we study whether this is a result
of differences in (1) the frequency, (2) intensity, and/or (3) duration of local
SARS-CoV-2 outbreaks depending on the local housing situations. So far, there
is not clear evidence which of the three factors dominates. Using small-scale
data from neighborhoods in the German city Essen and a flexible estimation approach
which does not require prior knowledge about specific transmission characteristics
of SARS-CoV-2, behavioral responses or other potential model parameters, we find
evidence for the last of the three hypotheses. Outbreaks do not happen more often
in less well-off areas or are more severe (in terms of the number of cases), but
they last longer. This indicates that the socio-economic gradient in infection
levels is at least in parts a result of a more sustained spread of infections
in neighborhoods with worse housing conditions after local outbreaks and suggests
that in case of an epidemic allocating scarce resources in containment measures
to areas with poor housing conditions might have the greatest benefit.

text: "AbstractThe interaction of acute exercise
and the central nervous system evokes increasing interest in interdisciplinary
research fields of neuroscience. Novel approaches allow to monitor large-scale
brain networks from mobile electroencephalography (EEG) applying graph theory,
but it is yet uncertain whether brain graphs extracted after exercise are reliable.
We therefore aimed to investigate brain graph reliability extracted from resting
state EEG data before and after submaximal exercise twice within one week in male
participants. To obtain graph measures, we extracted global small-world-index
(SWI), clustering coefficient (CC) and characteristic path length (PL) based on
weighted phase leg index (wPLI) and spectral coherence (Coh) calculation. For
reliability analysis, Intraclass-Correlation-Coefficient (ICC) and Coefficient
of Variation (CoV) were computed for graph measures before (REST) and after POST)
exercise. Overall results revealed poor to excellent measures at PRE and good
to excellent ICCs at POST in the theta, alpha-1 and alpha-2, beta-1 and beta-2
frequency band. Based on bootstrap-analysis, a positive effect of exercise on
reliability of wPLI based measures was observed, while exercise induced a negative
effect on reliability of Coh-based graph measures. Findings indicate that brain
graphs are a reliable tool to analyze brain networks in exercise contexts, which
might be related to the neuroregulating effect of exercise inducing functional
connections within the connectome. Relative and absolute reliability demonstrated
good to excellent reliability after exercise. Chosen graph measures may not only
allow analysis of acute, but also longitudinal studies in exercise-scientific
contexts.\r\n"

text: AbstractAnorexia nervosa (AN) is a severe
eating disorder and often associated with altered humoral immune responses. However,
distinct B cell maturation stages in peripheral blood in adolescents with AN have
not been characterized. Treatment effects and the relationship between clinical
and B cell parameters are also not fully understood. Here we investigated the
phenotype of circulating B cell subsets and the relationship with body composition
in adolescents with AN before (T0, n = 24) and after 6 weeks (T1, n = 20) of treatment.
Using multi-parameter flow cytometry, we found increased percentages of antigen-experienced
B cells and plasmablasts in patients with AN compared to healthy controls (n = 20).
In contrast, percentages of CD1d+CD5+
B cells and transitional B cells with immunoregulatory roles were reduced at T0
and T1. These B cell frequencies correlated positively with fat mass, fat mass
index (FMI), free fat mass index, and body mass index standard deviation score.
In addition, scavenger-like receptor CD5 expression levels were downregulated
on transitional B cells and correlated with fat mass and FMI in AN. Our findings
that regulatory B cell subgroups were reduced in AN and their strong relationship
with body composition parameters point toward an impact of immunoregulatory B
cells in the pathogenesis of AN.

text: AbstractVibrational sum-frequency generation
(vSFG) spectroscopy allows the study of the structure and dynamics of interfacial
systems. In the present work, we provide a simple recipe, based on a narrowband
IR pump and broadband vSFG probe technique, to computationally obtain the two-dimensional
vSFG spectrum of water molecules at the air–water interface. Using this technique,
to study the time-dependent spectral evolution of hydrogen-bonded and free water
molecules, we demonstrate that at the interface, the vibrational spectral dynamics
of the free OH bond is faster than that of the bonded OH mode.

text: AbstractA detailed investigation of the energy
levels of perylene-3,4,9,10-tetracarboxylic tetraethylester as a representative
compound for the whole family of perylene esters was performed. It was revealed
via electrochemical measurements that one oxidation and two reductions take place.
The bandgaps determined via the electrochemical approach are in good agreement
with the optical bandgap obtained from the absorption spectra via a Tauc plot.
In addition, absorption spectra in dependence of the electrochemical potential
were the basis for extensive quantum-chemical calculations of the neutral, monoanionic,
and dianionic molecules. For this purpose, calculations based on density functional
theory were compared with post-Hartree–Fock methods and the CAM-B3LYP functional
proved to be the most reliable choice for the calculation of absorption spectra.
Furthermore, spectral features found experimentally could be reproduced with vibronic
calculations and allowed to understand their origins. In particular, the two lowest
energy absorption bands of the anion are not caused by absorption of two distinct
electronic states, which might have been expected from vertical excitation calculations,
but both states exhibit a strong vibronic progression resulting in contributions
to both bands.

have been extensively used for the realization of a wide range of optical and
electronic devices. Exploiting their potential for further improvement and development
requires a fundamental understanding of their electronic structure. So far, the
most commonly used experimental techniques for this purpose have been all-optical
spectroscopy methods that, however, are generally averaging in momentum space.
Additional information can be gained by angle-resolved photoelectron spectroscopy
(ARPES), which measures the electronic structure with momentum resolution. Here
we report on the use of extremely low-energy ARPES (photon energy ~ 7 eV) to increase
depth sensitivity and access buried QW states, located at 3 nm and 6 nm below
the surface of cubic-GaN/AlN and GaAs/AlGaAs heterostructures, respectively. We
find that the QW states in cubic-GaN/AlN can indeed be observed, but not their
energy dispersion, because of the high surface roughness. The GaAs/AlGaAs QW states,
on the other hand, are buried too deep to be detected by extremely low-energy
ARPES. Since the sample surface is much flatter, the ARPES spectra of the GaAs/AlGaAs
show distinct features in momentum space, which can be reconducted to the band
structure of the topmost surface layer of the QW structure. Our results provide
important information about the samples’ properties required to perform extremely
low-energy ARPES experiments on electronic states buried in semiconductor heterostructures.

text: 'AbstractIn three experiments, we investigated
the effect of unconscious social priming on human behavior in a choice reaction
time task. Photographs of a basketball player passing a ball to the left/right
were used as target stimuli. Participants had to respond to the pass direction
either by a whole-body (complex) response or a button-press (simple) response.
Visually masked stimuli, showing both a task-relevant cue (pass direction) and
a task-irrelevant, social cue (gaze direction), were used as primes. Subliminal
social priming was found for kinematic (center of pressure) and chronometric measures
(response times): gaze direction in the primes affected responses to the pass
direction in the targets. The social priming effect diminished when gaze information
was unhelpful or even detrimental to the task. Social priming of a complex behavior
does not require awareness or intentionality, indicating automatic processing.
Nevertheless, it can be controlled by top-down, strategic processes.'

text: "Dodecyl amine edge functionalized few-layer graphene oxide quantum dots were
synthesized in good\r\nyields. The covalent functionalization was demonstrated
with NMR and AFM-IR. The resulting structure\r\nand particle size was measured
with AFM and HRTEM. The thermal stability of the compound was\r\ninvestigated
and showed a stability of up to 220 °C. The modified graphene oxide quantum dots
showed\r\nexcellent solubility in various organic solvents, including ethers,
methanol, toluene, n-hexane, heptane,\r\nxylene, dichloromethane and toluene.
The stability of a resulting toluene solution was also proven by\r\nstatic light
scattering measurements over several days. The excellent solubility gives the
possibility of an\r\nefficient and fast spray application of the functionalized
graphene oxide quantum dots to steel surfaces.\r\nHence, the macroscopic friction
behavior was investigated with a Thwing-Albert FP-2250 friction tester. A\r\nthin
film of the dodecyl amine functionalized graphene oxide quantum dots on steel
lowered the friction\r\ncoefficient from 0.17 to 0.11 and revealed a significant
corrosion inhibition effect."
