Authors: Liu Xiaohua , Huang Ding , Landon Mark B. , Cheng Weiwei , Chen Yan 
Published: March 2020

Abstract
Objective We aimed to describe changes in cesarean delivery (CD) rates after the change of the one-child policy in China by using the Robson classification in a large Chinese population.
Study Design This retrospective cohort study included 91,015 women who delivered at ≥24 weeks of gestation at a large tertiary obstetric center in Shanghai, China from 2011 to 2016. We analyzed CD rate trend and CD contribution trend in each Robson group. Logistic regression was used to calculate the odds of CD while adjusting for confounding variables.
Results The overall CD rate decreased from 49.0% in 2011 to 40.6% in 2016. In nulliparous women with singleton cephalic term pregnancy and planned CD, the CD contribution rate was reduced significantly from 29.3% in 2011 to 16.4% in 2016 (p < 0.001). In multiparous with a scarred uterus, the CD contribution rate began to increase from 3.8% in 2011 to 9.1% in 2016 (p < 0.001). Compared with delivery in 2011, delivery in 2016 was associated with a 37% (adjusted odds ratio [aOR]: 0.63; 95% confidence interval [CI]: 0.60–0.66) reduction in CD. This reduction was observed in both nulliparous women with singleton cephalic term pregnancy (aOR: 0.57; 95% CI: 0.54–0.60), and multiparous women with singleton cephalic term pregnancy without scar (aOR: 0.41; 95% CI: 0.30–0.55).
Conclusion The rate of cesarean delivery in our Chinese population has declined significantly in the past few years.

Published: March 2020

Abstract
Objective Pulmonary hypertension (PH) has been described in the neonatal omphalocele population. This study was aimed to describe cardiac function and PH severity using echocardiography in newborns with giant omphalocele (GO) and with non-GO and determine if right ventricular (RV) dysfunction is associated with mortality.
Study Design Retrospective, single-center analysis of first echocardiography among neonatal omphalocele patients born between 2004 and 2017 was conducted. Multivariate logistic and univariate Cox's regression was constructed to measure hazard ratio (HR) for death outcome.
Results There were 32 newborns, of whom 18 were GO and 7 died. GO had increased systolic pulmonary arterial to systolic systemic blood pressure ratio (97% [isosystemic] vs. 73% [three-fourths systemic] p = 0.03). RV performance parameters (tricuspid annular plane excursion, HR = 0.40; fractional area change, HR = 0.90; and RV peak global longitudinal strain, HR = 1.39) were associated with mortality. These RV performance parameters remained associated in a multiple logistic regression accounting for gestational age and GO status. The overall population had abnormal eccentricity index and pulmonary artery acceleration time to RV ejection time ratio, two markers of PH.
Conclusion Patients with omphalocele have increased pulmonary pressure, with GO being worse than non-GO. RV dysfunction at initial echocardiography was significantly associated with mortality.

Published: March 2020

Abstract
Aim NIH3T3 cell line with expression of human receptor for advanced glycation end-products (hRAGE) transduced with lentivirus vectors was used to analyze affinity, biological activity, and/or molecular mechanisms of molecules targeting the hRAGE pathway.
Method The DNA fragment coding for hRAGE gene was integrated into the genome of NIH3T3 cells using lentivirus transduction. Cells expressing hRAGE were selected with puromycin, and the level of hRAGE expression was analyzed by Western blot. To establish a stable cell line, colonies of hRAGE-expressing cells were generated, and the level of RAGE expression in each engineered cell line was analyzed within 20 generations. Flow cytometry assay was used to verify affinity of anti-hRAGE antibody binding to hRAGE on the surface of engineered cells. The engineered NIH3T3 cell line was applied to assess effects of anti-hRAGE blocking antibody on amyloid β-induced cells apoptosis by CCK-8 assay.
Results The engineered NIH3T3 cell line (hRAGE-NIH3T3) could stably express human RAGE. Commercial anti-RAGE polyclonal antibody could recognize and bind to human RAGE on the surface of hRAGE-NIH3T3 but not original NIH3T3 cells. In addition, hRAGE-NIH3T3 was more sensitive to RAGE pathway-dependent stimulation. Our data show that the hRAGE-NIH3T3 cell line established is an excellent tool in the study of RAGE-targeting molecules based on the cellular level, biological function, and RAGE-mediated molecular mechanisms.
The eye or the ear?

Published: March 2020

Abstract
In the current study we set out to investigate source language interference in the visual modality (in sight
translation – ST) and in the auditory modality (in simultaneous interpreting – SI). We probed interpretations of cognates,
interlingual homographs and passive structures in single sentence contexts as performed from English to Polish by 47 advanced
interpreting trainees. We also analysed temporal measures: ear-voice span (in SI) or eye-voice span (in ST) as well as total
translation time. The results showed a higher level of interference in ST in the case of homographs and a mixed pattern of results
for the remaining measures. We also obtained interesting task-independent results, namely an 80% rate of global passive retention
testifying to a high level of syntactic priming in both modes of interpreting. We discuss these results in the context of
different types of interference occurring in interpreting and conclude that there might be a similar global level of interference
in the two tasks, however with differing underlying patterns. This is the first study to date to directly compare interference
levels between ST and SI in such controlled conditions. Our results contribute to the understanding of complex linguistic
processes occurring across modalities in interpreting tasks.
Cross-linguistic influence in word order
Authors: Bosch Jasmijn E. , Unsworth Sharon 
Published: March 2020

Abstract
The present study investigated cross-linguistic influence (CLI) in the word order of Dutch-English bilingual children, using elicited production and acceptability judgment tasks. The goal was to examine whether monolingual and bilingual children produced and/or accepted V2 word orders in English, as in * Yesterday painted she an apple. We investigated whether the likelihood of CLI was related to language dominance, age at testing, and the degree of surface overlap (i.e., V2 word orders with auxiliaries versus main verbs).
Even though none of the participants produced V2 word orders in English, in the acceptability judgment task bilingual children were more likely to accept V2 word orders than monolingual peers. Whilst monolinguals sometimes accepted V2 word orders with auxiliaries, bilinguals did so significantly more often (constituting a quantitative difference) and with main verbs, too (implying a qualitative difference). Therefore, we conclude that CLI can occur independently of surface overlap and that it can lead to both quantitative and qualitative differences between bilinguals and monolinguals. The likelihood of CLI was predicted by language dominance, but not by age. Some bilinguals still accepted V2 word orders at age ten, suggesting that in some cases CLI may be more persistent than previously thought.

Abstract

Reactive oxygen species and nitric oxide (NO•) concomitantly play essential roles in guard cell signaling. Studies using catalase mutants have revealed that the inducible and constitutive elevations of intracellular hydrogen peroxide (H2O2) have different roles: only the inducible H2O2 production transduces the abscisic acid (ABA) signal leading stomatal closure. However, the involvement of inducible or constitutive NO• productions, if exists, in this process remains unknown. We studied H2O2 and NO• mobilization in guard cells of catalase mutants. Constitutive H2O2 level was higher in the mutants than that in wild type, but constitutive NO• level was not different among lines. Induced NO• and H2O2 levels elicited by ABA showed a high correlation with each other in all lines. Furthermore, NO• levels increased by exogenous H2O2 also showed a high correlation with stomatal aperture size. Our results demonstrate that ABA-induced intracellular H2O2 accumulation triggers NO• production leading stomatal closure.

Recent bounds on graviton mass using galaxy clusters
Authors: Desai Shantanu , Gupta Sajal 
Published: March 2020

Abstract
Although galaxy clusters have proved to be wonderful laboratories for testing a plethora of modified gravity theories and other exotic alternatives to ΛCDM, until a few years ago, there was only one paper (from 1974), which obtained a limit on graviton mass (of

O

(10−29) eV) with clusters. To rectify this, in the last few years multiple works have obtained different bounds on graviton mass using single cluster data as well as stacking galaxy catalogs. We review these recent limits on graviton mass using galaxy clusters obtained using disparate methods.

Abstract
POLARBEAR is a Cosmic Microwave Background radiation (CMB) polarization experiment that is located in the Atacama Desert in Chile. The scientific goals of the experiment are to characterize the B-mode signal from gravitational lensing, as well as to search for B-mode signals created by primordial gravitational waves (PGWs). Polarbear started observations in 2012 and has published a series of results. These include the first measurement of a nonzero B-mode angular auto-power spectrum at sub-degree scales where the dominant signal is gravitational lensing of the CMB. In addition, we have achieved the first measurement of crosscorrelation between the lensing potential, which was reconstructed from the CMB polarization data alone by Polarbear, and the cosmic shear field from galaxy shapes by the Subaru Hyper Suprime-Cam (HSC) survey. In 2014, we installed a continuously rotating half-wave plate (CRHWP) at the focus of the primary mirror to search for PGWs and demonstrated the control of low-frequency noise. We have found that the low-frequency B-mode power in the combined dataset with the Planck high-frequency maps is consistent with Galactic dust foreground, thus placing an upper limit on the tensor-to-scalar ratio of r < 0.90 at the 95% confidence level after marginalizing over the foregrounds.
Dark matter signals on laser interferometer

Published: March 2020

Abstract
WIMPs are promising dark matter candidates. When WIMPs collide with a mirror equipped with interferometric gravitational wave detectors, we expect that characteristic motions of the pendulum and mirror are excited, and those signals could be extracted by highly sophisticated sensors developed for gravitational wave detection. We analyze the motions of the pendulum and mirror, and estimate the detectability of these motions. For the “Thin-ET” detector, the signal to noise ratio may be

DM = 0.2 GeV.

We compute the WIMP-nucleon cross section in leptoquark portal and the relic density mediated by inert doublet components, leptoquark and the new Z′ boson. We constrain the parameter space consistent with Planck limit on relic density, PIC0-60 and LUX bounds on spin-dependent direct detection cross section. We also discuss about the neutrino mass generation at one-loop level and the viable parameter region to explain current neutrino oscillation data. The Z′ gauge boson of extended U(1) symmetry and the SLQ play an important role in settling the known issues of flavor sector.

Dark Matter searches through cross-correlations of gamma rays with neutral-hydrogen intensity mapping
Authors: Pinetti Elena 
Published: March 2020

Abstract
In this work we derive the first theoretical prediction of the cross-correlation signal between the unresolved gamma-ray background and the 21-cm line originated by the spin-flip transition of neutral hydrogen atoms, by taking as benchmark experiment the space telescope Fermi-LAT for gamma rays and the next-generation radio telescope Square Kilometer Array (SKA) as well as its precursor MeerKAT for the 21-cm emission. The attainable bounds in the dark matter (DM) parameter space are envisioned to be competitive already with the combination Fermi-LAT × MeerKAT, but SKA will allow to go deeper and probe a thermal DM particle up to masses of 130 GeV. A future gamma-ray detector with better angular resolution and larger exposure together with an ungraded radio telescope will have the potentiality to probe a DM candidate with thermal annihilation cross-section and masses up to the TeV scale.
Study of luminescence mechanism by neutral bremsstrahlung in gaseous argon
Authors: Takeda T , Tanaka M , Yorita K 
Published: March 2020

Abstract
Secondary scintillation light (S2 signal) has been used for direct dark matter search in two-phase detectors because of its appealing characters. In general, electrons extracted from the liquid phase of two-phase detectors produce excimers in the gaseous phase that emit a VUV (vacuum ultraviolet) S2 signal. However, recent research suggests that the S2 signal in argon has another luminescence mechanism called "neutral bremsstrahlung". In this work, detailed measurements of neutral-bremsstrahlung-induced -S2 -signal (and also VUV S2 signal) in argon are reported.
Local shower age and segmented slope parameters of lateral density distributions of cosmic ray shower particles
Authors: Dey Rajat K. 
Published: March 2020

Abstract
The paper describes lateral density distributions of electrons and muons of cosmic ray extensive air showers (EAS) in the energy regime of the KASCADE experiment. Potential EAS observables are extracted while some suitable lateral distribution functions are introduced to describe these lateral density distributions of simulated/observed cosmic ray showers. Mass-sensitivity of these parameters are demonstrated particularly for the KASCADE electron and muon distributions data. Our studies indicate that the KASCADE data favours an idea of gradual change of cosmic ray mass composition from lighter concentration to heavier concentration in terms of these parameters.
Equation of state for quark matter with strong magnetic field and hybrid stars
Authors: Endo Tomoki , Sotani Hajime , Tatsumi Toshitaka 
Published: March 2020

Abstract
Our previous studies indicate that quark matter in the states of the lowest Landau level of a strong magnetic field must be described by a stiffer equation of state and a mass for the hybrid star that easily rises above 2M⊙. In contrast, the inclusion of higher Landau levels may permit a softer equation of state. Because this general scenario seems to be complex, as a first step, we look into introducing only the second Landau level to elicit trends. We find that to sustain a heavy star of mass 2M⊙, the equation of state must remain sufficiently stiff. We also discuss the mass-radius relation for these hybrid stars in the light of recent observations.
Diffusive shock acceleration of cosmic rays in low-Mach galaxy cluster shocks.
Authors: Marle Allard Jan van 
Published: March 2020

Abstract
Astrophysical shocks are known to accelerate particles to high relativistic velocities. This process requires the particles to repeatedly cross the shock, a process that can only occur if the particle is reflected by the local magnetic field. Such particles are observed on Earth as cosmic rays. This phenomenon has been studied in considerable detail for high-Mach shocks, such as the shocks that occur in colliding stellar winds and supernova explosions, but remains relatively unexplored for low-Mach shocks, such as the shocks of colliding clusters of galaxies. Recent simulations using the particle-in-cell (PIC) method have shown that, depending on the exact Mach number, even low-Mach shocks can accelerate charged particles to the point where they start to deviate from the thermal velocity distribution. However, the computationally intensive nature of the PIC calculations makes it difficult to continue the simulations to determine whether the particles can reach relativistic speeds. We now present new simulations, using a combined PIC and magnetohydrodynamics (MHD) technique. This model, which takes advantage of the computational efficiency of MHD, allows us to simulate a much larger physical volume and study the behaviour of the particles over a longer period of time in order to determine to what extent the acceleration process continues and whether these shocks are capable of contributing to the cosmic ray spectrum.

A new neutrinoless double beta decay experiment: R2D2
Authors: Jollet Cécile 
Published: March 2020

Abstract
The search for neutrinoless double beta decay could cast light on one critical piece missing in our knowledge i.e. the nature of the neutrino mass. Its observation is indeed the most sensitive experimental way to prove that neutrino is a Majorana particle. The observation of such a potentially rare process demands a detector with an excellent energy resolution, an extremely low radioactivity and a large mass of emitter isotope. Nowadays many techniques are pursued but none of them meets all the requirements at the same time. The goal of R2D2 is to prove that a spherical high pressure TPC could meet all the requirements and provide an ideal detector for the 0vββ decay search. In the presented talk the R2D2 goal and preliminary results are presented as well as the project roadmap.
