text: Over 2,000 stars were observed for 1 month with a high enough cadence in order
to look for acoustic modes during the survey phase of the Kepler mission. Solar-like
oscillations have been detected in about 540 stars. The question of why no oscillations
were detected in the remaining stars is still open. Previous works explained the
non-detection of modes with the high level of magnetic activity of the stars.
However, the sample of stars studied contained some classical pulsators and red
giants that could have biased the results. In this work, we revisit this analysis
on a cleaner sample of main-sequence solar-like stars that consists of 1,014 stars.
First we compute the predicted amplitude of the modes of that sample and for the
stars with detected oscillation and compare it to the noise at high frequency
in the power spectrum. We find that the stars with detected modes have an amplitude
to noise ratio larger than 0.94. We measure reliable rotation periods and the
associated photometric magnetic index for 684 stars out of the full sample and
in particular for 323 stars where the amplitude of the modes is predicted to be
high enough to be detected. We find that among these 323 stars 32% of them have
a level of magnetic activity larger than the Sun during its maximum activity,
explaining the non-detection of acoustic modes. Interestingly, magnetic activity
cannot be the primary reason responsible for the absence of detectable modes in
the remaining 68% of the stars without acoustic modes detected and with reliable
rotation periods. Thus, we investigate metallicity, inclination angle of the rotation
axis, and binarity as possible causes of low mode amplitudes. Using spectroscopic
observations for a subsample, we find that a low metallicity could be the reason
for suppressed modes. No clear correlation with binarity nor inclination is found.
We also derive the lower limit for our photometric activity index (of 20–30 ppm)
below which rotation and magnetic activity are not detected. Finally, with our
analysis we conclude that stars with a photometric activity index larger than
2,000 ppm have 98.3% probability of not having oscillations detected.

text: The NASA Transiting Exoplanet Survey Satellite (TESS) is about to provide
full-frame images of almost the entire sky. The amount of stellar data to be analysed
represents hundreds of millions stars, which is several orders of magnitude more
than the number of stars observed by the Convection, Rotation and planetary Transits
satellite (CoRoT), and NASA Kepler and K2 missions. We aim at automatically classifying
the newly observed stars with near real-time algorithms to better guide the subsequent
detailed studies. In this paper, we present a classification algorithm built to
recognise solar-like pulsators among classical pulsators. This algorithm relies
on the global amount of power contained in the power spectral density (PSD), also
known as the flicker in spectral power density (FliPer). Because each type of
pulsating star has a characteristic background or pulsation pattern, the shape
of the PSD at different frequencies can be used to characterise the type of pulsating
star. The FliPer classifier (FliPerClass) uses different FliPer parameters along
with the effective temperature as input parameters to feed a ML algorithm in order
to automatically classify the pulsating stars observed by TESS. Using noisy TESS-simulated
data from the TESS Asteroseismic Science Consortium (TASC), we classify pulsators
with a 98% accuracy. Among them, solar-like pulsating stars are recognised with
a 99% accuracy, which is of great interest for a further seismic analysis of these
stars, which are like our Sun. Similar results are obtained when we trained our
classifier and applied it to 27-day subsets of real Kepler data. FliPerClass is
part of the large TASC classification pipeline developed by the TESS Data for
Asteroseismology (T’DA) classification working group.

text: The recently published Kepler mission Data Release 25 (DR25) reported on ∼197 000
targets observed during the mission. Despite this, no wide search for red giants
showing solar-like oscillations have been made across all stars observed in Kepler’s
long-cadence mode. In this work, we perform this task using custom apertures on
the Kepler pixel files and detect oscillations in 21 914 stars, representing the
largest sample of solar-like oscillating stars to date. We measure their frequency
at maximum power, νmax, down to νmax≃4μHz and obtain log (g) estimates with a
typical uncertainty below 0.05 dex, which is superior to typical measurements
from spectroscopy. Additionally, the νmax distribution of our detections show
good agreement with results from a simulated model of the Milky Way, with a ratio
of observed to predicted stars of 0.992 for stars with 10<νmax<270μHz. Among our
red giant detections, we find 909 to be dwarf/subgiant stars whose flux signal
is polluted by a neighbouring giant as a result of using larger photometric apertures
than those used by the NASA Kepler science processing pipeline. We further find
that only 293 of the polluting giants are known Kepler targets. The remainder
comprises over 600 newly identified oscillating red giants, with many expected
to belong to the Galactic halo, serendipitously falling within the Kepler pixel
files of targeted stars.

text: We present the discovery of HD 221416 b, the first transiting planet identified
by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology
of the host star is possible. HD 221416 b (HIP 116158, TOI-197) is a bright (V
= 8.2 mag), spectroscopically classified subgiant that oscillates with an average
frequency of about 430 μHz and displays a clear signature of mixed modes. The
oscillation amplitude confirms that the redder TESS bandpass compared to Kepler
has a small effect on the oscillations, supporting the expected yield of thousands
of solar-like oscillators with TESS 2 minute cadence observations. Asteroseismic
modeling yields a robust determination of the host star radius (R⋆ = 2.943 ± 0.064
R⊙), mass (M⋆ = 1.212 ± 0.074 M⊙), and age (4.9 ± 1.1 Gyr), and demonstrates that
it has just started ascending the red-giant branch. Combining asteroseismology
with transit modeling and radial-velocity observations, we show that the planet
is a "hot Saturn" (Rp = 9.17 ± 0.33 R⊕) with an orbital period of ∼14.3 days,
irradiance of F = 343 ± 24 F⊕, and moderate mass (Mp = 60.5 ± 5.7 M⊕) and density
(ρp = 0.431 ± 0.062 g cm−3). The properties of HD 221416 b show that the host-star
metallicity–planet mass correlation found in sub-Saturns (4–8 R⊕) does not extend
to larger radii, indicating that planets in the transition between sub-Saturns
and Jupiters follow a relatively narrow range of densities. With a density measured
to ∼15%, HD 221416 b is one of the best characterized Saturn-size planets to date,
augmenting the small number of known transiting planets around evolved stars and
demonstrating the power of TESS to characterize exoplanets and their host stars
using asteroseismology.

text: Brightness variations due to dark spots on the stellar surface encode information
about stellar surface rotation and magnetic activity. In this work, we analyze
the Kepler long-cadence data of 26,521 main-sequence stars of spectral types M
and K in order to measure their surface rotation and photometric activity level.
Rotation-period estimates are obtained by the combination of a wavelet analysis
and autocorrelation function of the light curves. Reliable rotation estimates
are determined by comparing the results from the different rotation diagnostics
and four data sets. We also measure the photometric activity proxy Sph using the
amplitude of the flux variations on an appropriate timescale. We report rotation
periods and photometric activity proxies for about 60% of the sample, including
4431 targets for which McQuillan et al. did not report a rotation period. For
the common targets with rotation estimates in this study and in McQuillan et al.,
our rotation periods agree within 99%. In this work, we also identify potential
polluters, such as misclassified red giants and classical pulsator candidates.
Within the parameter range we study, there is a mild tendency for hotter stars
to have shorter rotation periods. The photometric activity proxy spans a wider
range of values with increasing effective temperature. The rotation period and
photometric activity proxy are also related, with Sph being larger for fast rotators.
Similar to McQuillan et al., we find a bimodal distribution of rotation periods.

text: 'For a solar-like star, the surface rotation evolves with time, allowing in
principle to estimate the age of a star from its surface rotation period. Here
we are interested in measuring surface rotation periods of solar-like stars observed
by the NASA mission Kepler. Different methods have been developed to track rotation
signals in Kepler photometric light curves: time-frequency analysis based on wavelet
techniques, autocorrelation and composite spectrum. We use the learning abilities
of random forest classifiers to take decisions during two crucial steps of the
analysis. First, given some input parameters, we discriminate the considered Kepler

text: 'The second mission of NASA’s Kepler satellite, K2, has collected hundreds
of thousands of lightcurves for stars close to the ecliptic plane. This new sample
could increase the number of known pulsating stars and then improve our understanding
of those stars. For the moment only a few stars have been properly classified
and published. In this work, we present a method to automaticly classify K2 pulsating
stars using a Machine Learning technique called Random Forest. The objective is
to sort out the stars in four classes: red giant (RG), main-sequence Solar-like
stars (SL), classical pulsators (PULS) and Other. To do this we use the effective
temperatures and the luminosities of the stars as well as the FliPer features,
that measures the amount of power contained in the power spectral density. The
classifier now retrieves the right classification for more than 80% of the stars.'

text: As genome-wide association studies (GWAS) increased in size, numerous gene-environment
interactions (GxE) have been discovered, many of which however explore only one
environment at a time and may suffer from statistical artefacts leading to biased
interaction estimates. Here we propose a maximum likelihood method to estimate
the contribution of GxE to complex traits taking into account all interacting
environmental variables at the same time, without the need to measure any. This
is possible because GxE induces fluctuations in the conditional trait variance,
the extent of which depends on the strength of GxE. The approach can be applied
to continuous outcomes and for single SNPs or genetic risk scores (GRS). Extensive
simulations demonstrated that our method yields unbiased interaction estimates
and excellent confidence interval coverage. We also offer a strategy to distinguish
specific GxE from general heteroscedasticity (scale effects). Applying our method
to 32 complex traits in the UK Biobank reveals that for body mass index (BMI)
the GRSxE explains an additional 1.9% variance on top of the 5.2% GRS contribution.
However, this interaction is not specific to the GRS and holds for any variable
similarly correlated with BMI. On the contrary, the GRSxE interaction effect for
leg impedance Embedded Image is significantly (P < 10−56) larger than it would
be expected for a similarly correlated variable Embedded Image. We showed that
our method could robustly detect the global contribution of GxE to complex traits,
which turned out to be substantial for certain obesity measures.

text: "The input to the token swapping problem is a graph with vertices v1, v2,
. . . , vn, and n tokens with labels 1,2, . . . , n, one on each vertex. The
goal is to get token i to vertex vi for all i= 1, . . . , n using a minimum number
of swaps, where a swap exchanges the tokens on the endpoints of an edge.Token
swapping on a tree, also known as “sorting with a transposition tree,” is not
known to be in P nor NP-complete. We present some partial results:\r\n1. An
optimum swap sequence may need to perform a swap on a leaf vertex that has the
correct token (a “happy leaf”), disproving a conjecture of Vaughan.\r\n2. Any
algorithm that fixes happy leaves—as all known approximation algorithms for the
problem do—has approximation factor at least 4/3. Furthermore, the two best-known
2-approximation algorithms have approximation factor exactly 2.\r\n3. A generalized
problem—weighted coloured token swapping—is NP-complete on trees, but solvable
in polynomial time on paths and stars. In this version, tokens and vertices
\ have colours, and colours have weights. The goal is to get every
token to a vertex of the same colour, and the cost of a swap is the sum of the
weights of the two tokens involved."

text: Despite their different origins, Drosophila glia and hemocytes are related
cell populations that provide an immune function. Drosophila hemocytes patrol
the body cavity and act as macrophages outside the nervous system whereas glia
originate from the neuroepithelium and provide the scavenger population of the
nervous system. Drosophila glia are hence the functional orthologs of vertebrate
microglia, even though the latter are cells of immune origin that subsequently
move into the brain during development. Interestingly, the Drosophila immune cells
within (glia) and outside the nervous system (hemocytes) require the same transcription
factor Glide/Gcm for their development. This raises the issue of how do glia specifically
differentiate in the nervous system and hemocytes in the procephalic mesoderm.
The Repo homeodomain transcription factor and pan-glial direct target of Glide/Gcm
is known to ensure glial terminal differentiation. Here we show that Repo also
takes center stage in the process that discriminates between glia and hemocytes.
First, Repo expression is repressed in the hemocyte anlagen by mesoderm-specific
factors. Second, Repo ectopic activation in the procephalic mesoderm is sufficient
to repress the expression of hemocyte-specific genes. Third, the lack of Repo
triggers the expression of hemocyte markers in glia. Thus, a complex network of
tissue-specific cues biases the potential of Glide/Gcm. These data allow us to
revise the concept of fate determinants and help us understand the bases of cell
specification. Both sexes were analyzed.SIGNIFICANCE STATEMENTDistinct cell types
often require the same pioneer transcription factor, raising the issue of how
does one factor trigger different fates. In Drosophila, glia and hemocytes provide
a scavenger activity within and outside the nervous system, respectively. While
they both require the Glide/Gcm transcription factor, glia originate from the
ectoderm, hemocytes from the mesoderm. Here we show that tissue-specific factors
inhibit the gliogenic potential of Glide/Gcm in the mesoderm by repressing the
expression of the homeodomain protein Repo, a major glial-specific target of Glide/Gcm.
Repo expression in turn inhibits the expression of hemocyte-specific genes in
the nervous system. These cell-specific networks secure the establishment of the
glial fate only in the nervous system and allow cell diversification.

and a Gross–Pitaevskii (GP) limit where the trap frequency ω, the temperature
T, and the particle number N are related by N∼ (T/ ω) 3→ ∞ while the scattering
length is so small that the interaction energy per particle around the center
of the trap is of the same order of magnitude as the spectral gap in the trap.
We prove that the difference between the canonical free energy of the interacting
gas and the one of the noninteracting system can be obtained by minimizing the
GP energy functional. We also prove Bose–Einstein condensation in the following
sense: The one-particle density matrix of any approximate minimizer of the canonical
free energy functional is to leading order given by that of the noninteracting
gas but with the free condensate wavefunction replaced by the GP minimizer.'

text: 'Working memory, the ability to keep recently accessed information available
for immediate manipulation, has been proposed to rely on two mechanisms that appear
difficult to reconcile: self-sustained neural firing, or the opposite—activity-silent
synaptic traces. Here we review and contrast models of these two mechanisms, and
then show that both phenomena can co-exist within a unified system in which neurons
hold information in both activity and synapses. Rapid plasticity in flexibly-coding
neurons allows features to be bound together into objects, with an important emergent
property being the focus of attention. One memory item is held by persistent activity
in an attended or “focused” state, and is thus remembered better than other items.
Other, previously attended items can remain in memory but in the background, encoded
in activity-silent synaptic traces. This dual functional architecture provides
a unified common mechanism accounting for a diversity of perplexing attention
and memory effects that have been hitherto difficult to explain in a single theoretical
framework.'

text: We study edge asymptotics of poissonized Plancherel-type measures on skew
Young diagrams (integer partitions). These measures can be seen as generalizations
of those studied by Baik--Deift--Johansson and Baik--Rains in resolving Ulam's
problem on longest increasing subsequences of random permutations and the last
passage percolation (corner growth) discrete versions thereof. Moreover they interpolate
between said measures and the uniform measure on partitions. In the new KPZ-like
1/3 exponent edge scaling limit with logarithmic corrections, we find new probability
distributions generalizing the classical Tracy--Widom GUE, GOE and GSE distributions
from the theory of random matrices.

text: "Suppose that $n\\neq p^k$ and $n\\neq 2p^k$ for all $k$ and all primes $p$.
We prove that for any Hausdorff compactum $X$ with a free action of the symmetric
group $\\mathfrak S_n$ there exists an $\\mathfrak S_n$-equivariant map $X \\to\r\n{\\mathbb
R}^n$ whose image avoids the diagonal $\\{(x,x\\dots,x)\\in {\\mathbb R}^n|x\\in
{\\mathbb R}\\}$.\r\n Previously, the special cases of this statement for certain
$X$ were usually proved using the equivartiant obstruction theory. Such calculations
are difficult and may become infeasible past the first (primary) obstruction.
We\r\ntake a different approach which allows us to prove the vanishing of all
obstructions simultaneously. The essential step in the proof is classifying the
possible degrees of $\\mathfrak S_n$-equivariant maps from the boundary\r\n$\\partial\\Delta^{n-1}$
of $(n-1)$-simplex to itself. Existence of equivariant maps between spaces is
important for many questions arising from discrete mathematics and geometry, such
as Kneser's conjecture, the Square Peg conjecture, the Splitting Necklace problem,
and the Topological Tverberg conjecture, etc. We demonstrate the utility of our
result applying it to one such question, a specific instance of envy-free division
problem."

text: "Denote by ∆N the N-dimensional simplex. A map f : ∆N → Rd is an almost r-embedding
if fσ1∩. . .∩fσr = ∅ whenever σ1, . . . , σr are pairwise disjoint faces. A counterexample
to the topological Tverberg conjecture asserts that if r is not a prime power
and d ≥ 2r + 1, then there is an almost r-embedding ∆(d+1)(r−1) → Rd. This was
improved by Blagojevi´c–Frick–Ziegler using a simple construction of higher-dimensional
counterexamples by taking k-fold join power of lower-dimensional ones. We improve
this further (for d large compared to r): If r is not a prime power and N := (d+
1)r−r l\r\nd + 2 r + 1 m−2, then there is an almost r-embedding ∆N → Rd. For the
r-fold van Kampen–Flores conjecture we also produce counterexamples which are
stronger than previously known. Our proof is based on generalizations of the Mabillard–Wagner
theorem on construction of almost r-embeddings from equivariant maps, and of the
Ozaydin theorem on existence of equivariant maps. "

text: "In this paper we study envy-free division problems. The classical approach
to some of such problems, used by David Gale, reduces to considering continuous
maps of a simplex to itself and finding sufficient conditions when this map hits
the center of the simplex. The mere continuity is not sufficient for such a conclusion,
the usual assumption (for example, in the Knaster--Kuratowski--Mazurkiewicz and
the Gale theorem) is a certain boundary condition.\r\n We follow Erel Segal-Halevi,
Fr\\'ed\\'eric Meunier, and Shira Zerbib, and replace the boundary condition by
another assumption, which has the economic meaning of possibility for a player
to prefer an empty part in the segment\r\npartition problem. We solve the problem
positively when $n$, the number of players that divide the segment, is a prime
power, and we provide counterexamples for every $n$ which is not a prime power.
We also provide counterexamples relevant to a wider class of fair or envy-free
partition problems when $n$ is odd and not a prime power."

text: "Background: Atopics have a lower risk for malignancies, and IgE targeted
to tumors is superior to IgG in fighting cancer. Whether IgE-mediated innate or
adaptive immune surveillance can confer protection against tumors remains unclear.\r\nObjective:
We aimed to investigate the effects of active and passive immunotherapy to the
tumor-associated antigen HER-2 in three murine models differing in Epsilon-B-cell-receptor
expression affecting the levels of expressed IgE.\r\nMethods: We compared the
levels of several serum specific anti-HER-2 antibodies (IgE, IgG1, IgG2a, IgG2b,
IgA) and the survival rates in low-IgE ΔM1M2 mice lacking the transmembrane/cytoplasmic
domain of Epsilon-B-cell-receptors expressing reduced IgE levels, high-IgE KN1
mice expressing chimeric Epsilon-Gamma1-B-cell receptors with 4-6-fold elevated
serum IgE levels, and wild type (WT) BALB/c. Prior engrafting mice with D2F2/E2
mammary tumors overexpressing HER-2, mice were vaccinated with HER-2 or vehicle
control PBS using the Th2-adjuvant Al(OH)3 (active immunotherapy), or treated
with the murine anti-HER-2 IgG1 antibody 4D5 (passive immunotherapy).\r\nResults:
Overall, among the three strains of mice, HER-2 vaccination induced significantly
higher levels of HER-2 specific IgE and IgG1 in high-IgE KN1, while low-IgE ΔM1M2
mice had higher IgG2a levels. HER-2 vaccination and passive immunotherapy prolonged
the survival in tumor-grafted WT and low-IgE ΔM1M2 strains compared with treatment
controls; active vaccination provided the highest benefit. Notably, untreated
high-IgE KN1 mice displayed the longest survival of all strains, which could not
be further extended by active or passive immunotherapy.\r\nConclusion: Active
and passive immunotherapies prolong survival in wild type and low-IgE ΔM1M2 mice
engrafted with mammary tumors. High-IgE KN1 mice have an innate survival benefit
following tumor challenge."

text: Food proteins may get nitrated by various exogenous or endogenous mechanisms.
As individuals might get recurrently exposed to nitrated proteins via daily diet,
we aimed to investigate the effect of repeatedly ingested nitrated food proteins
on the subsequent immune response in non-allergic and allergic mice using the
milk allergen beta-lactoglobulin (BLG) as model food protein in a mouse model.
Evaluating the presence of nitrated proteins in food, we could detect 3-nitrotyrosine
(3-NT) in extracts of different foods and in stomach content extracts of non-allergic
mice under physiological conditions. Chemically nitrated BLG (BLGn) exhibited
enhanced susceptibility to degradation in simulated gastric fluid experiments
compared to untreated BLG (BLGu). Gavage of BLGn to non-allergic animals increased
interferon-γ and interleukin-10 release of stimulated spleen cells and led to
the formation of BLG-specific serum IgA. Allergic mice receiving three oral gavages
of BLGn had higher levels of mouse mast cell protease-1 (mMCP-1) compared to allergic
mice receiving BLGu. Regardless of the preceding immune status, non-allergic or
allergic, repeatedly ingested nitrated food proteins seem to considerably influence
the subsequent immune response.
