Published: May 2021

Objective: The purpose of this study was to explore the value of 18F-FDG PET/CT in monitoring the disease activity and predicting the prognosis of the Adult-onset Still's disease (AOSD).Methods: We retrospectively analyzed the electronic medical records of 45 AOSD patients who underwent 18F-FDG PET/CT in the Second Xiangya Hospital. PET/CT imaging and clinical information were retrospectively reviewed and analyzed. 18F-FDG uptake was assessed by measuring standard uptake value (SUV) in the spleen, liver, bone marrow, and lymph nodes. The spleen-to-liver ratio of the SUVmax (SLRmax) and SUVmean (SLRmean), the bone-to-liver ratio of the SUVmax (BLRmax), and SUVmean (BLRmean), and the lymph nodes-to-liver ratio of the SUVmax (LyLRmax) were calculated. Clinical and laboratory information were collected and evaluated for association with metabolic parameters of 18F-FDG PET/CT. The influencing factors for recurrence within 1 year were analyzed to determine whether 18F-FDG PET/CT can predict the prognosis of AOSD patients.Results: Elevated 18F-FDG uptake could be observed in bone marrow, spleen, and lymph nodes of AOSD patients. Correlation analysis between 18F-FDG uptake of organs and laboratory examinations showed that SLRmean positively correlated with LDH, AST, ferritin, and the systemic score (r = 0.572, 0.353, 0.586, and 0.424, P &lt; 0.05). The SLRmean had the highest correlation with ferritin (r = 0586, P &lt; 0.001). All metabolic parameters in spleen, including SUVmax, SUVmean, SLRmax, and SLRmean, are positively correlated with LDH level (r = 0.405, 0.539, 0.481, and 0.572, P &lt; 0.05). Bone marrow SUVmax, BLRmax, and BLRmean were correlated with C-reactive protein (CRP) level (r = 0.395, 0.437, and 0.469, P &lt; 0.05). Analysis of the influencing factors of recurrence within 1 year showed that the spleen SUVmax, spleen SUVmean, SLRmax, SLRmean, ferritin, and the systemic score of the recurrence group was significantly higher than the non-recurrence group (P &lt; 0.05). The SLRmean cutoff of 1.66 with a sensitivity of 72.7% and specificity of 80.0% had the highest performance in predicting recurrence.Conclusion: The glucose metabolism of the liver, spleen, and bone marrow of AOSD patients were correlated with laboratory inflammatory indicators and system score, suggesting that 18F-FDG PET/CT could be applied to evaluate disease activity. Moreover, spleen 18F-FDG uptake may be a potential biomarker for predicting clinical prognosis of AOSD patients.
Intermittent Theta-Burst Stimulation Transcranial Magnetic Stimulation Increases GABA in the Medial Prefrontal Cortex: A Preliminary Sham-Controlled Magnetic Resonance Spectroscopy Study in Acute Bipolar Depression

Published: May 2021

Background: Magnetic resonance spectroscopy (MRS) has been used to identify gamma-aminobutyric acid (GABA) alterations in mood disorders, particularly in the medial prefrontal cortex (mPFC) where decreased concentrations have been associated with anhedonia. In major depressive disorder (MDD), prior work suggests that repetitive transcranial magnetic stimulation (rTMS) increases mPFC GABA concentrations proportional to antidepressant response. To our knowledge, this has not been examined in acute bipolar depression.Methods: As part of a multicentre 4-week randomized, double-blind, sham-controlled trial using intermittent theta-burst stimulation (iTBS) of the left dorsolateral prefrontal cortex (DLPFC) in individuals with acute bipolar depression, we quantified mPFC GABA and Glx (glutamate+glutamine) concentrations using a 3T MRS scan at baseline and after the intervention. Depressive symptoms were measured using the Montgomery-Asberg Depression Rating Scale (MADRS) and the Hamilton Depression Rating Scale-17 (HRDS-17), and anhedonia was measured using the Snaith-Hamilton Pleasure Scale (SHAPS).Results: The trial was terminated for futility and magnetic resonance spectroscopy data was acquired for 18 participants. At baseline, there were no associations between GABA or Glx concentrations and anhedonia, however GABA was negative correlated with depressive symptom severity on the HRDS-17. Compared to the sham-iTBS group, participants receiving active-iTBS had a significant increase in mPFC GABA concentrations. This was unrelated to antidepressant outcomes or improvements in anhedonia.Conclusion: Our data suggests that iTBS targeting the DLPFC is associated with physiological changes in the mPFC. In acute bipolar depression, our preliminary data suggests that mPFC GABA is dissociated from antidepressant iTBS treatment outcomes and anhedonia.

The efficacy of two formulations (Foray® 76B AVIO and Rapax® AS AIR) containing different Bacillus thuringiensis kurstaki (Btk) strains (ABTS-351 and EG-2348, respectively) was evaluated against Lymantria dispar larval populations in cork oak forests in Sardinia (Italy), in 2018 and 2019. The experimental design involved the following treatments: (I) untreated control; (II) Foray® 76B at the dose of 2.0 L/ha; (III) Foray® 76B at the dose of 2.5 L/ha; (IV) Rapax® AS AIR at the dose of 2.0 L/ha. Aerial applications were carried out using a helicopter equipped with four electronic rotary atomizers adjusted to sprinkle 160 micron-sized drops. Btk efficacy was evaluated by assessing the larval density reduction 7, 14, and 21 days after the application in each experimental plot in comparison with an untreated check. In addition to field surveys, the mortality of second and third instar larval samples, randomly collected from each plot after treatment and fed with foliage from the same plot, was determined in the laboratory. All Btk treatments were similarly effective, and no differences in larval density reduction among Btk strains and doses were found in either year. Twenty-one days after application, the average larval density reduction in the field was approximately 70% in all treated plots in 2018, whereas in 2019 it reached 80% only in areas treated with Foray 76B at 2.5 L/ha. Laboratory observations showed that all Btk-based products were effective against gypsy moth larvae, with significant differences in mortality between untreated control and the different Btk treatments. Our results shed light on the possibility of alternating different Btk strains for resistance management purposes and of applying lower doses than labeled, in order to achieve cost savings for product shipment and distribution and to reduce the environmental impact.

Published: May 2021

Abstract
We systematically study geometries and band structures of two-dimensional group-V bilayer materials, i.e. phosphorene, arsenene and antimonene. Among the four stacking structures (AA, AB, AC, and AD), the AB stacking structures are found to be the largest band gaps and to be the most energetically stable. We find novel band structures on the whole Brillouin zone edges: four bands have close energies and two of the four bands have the same energy in many cases. We analyze the characteristic features of the band structures based on the group theory and clarify that the features depend on the space group of each stacking structure. We also find that the band splits due to the interlayer interaction is very small and this interaction becomes large as atoms become heavy.

Abstract
We demonstrated room-temperature pulsed-operations of GaN-based blue edge-emitting laser diodes (LDs) with both the top and bottom AlInN cladding layers by using GaN tunnel junctions (TJs) grown by metalorganic vapor phase epitaxy. The LDs with a 1.2 mm cavity length and a 15 μm ridge width were fabricated. We obtained a low threshold current density of 0.9 kA cm−2 with facet coating. We found that while an optical absorption loss in the waveguiding layer was reduced with a low Mg concentration (3 × 1018 cm−3), that in a highly doped TJ could be an obstacle to obtain further improvements of the laser characteristics.
Cranberry tree (Viburnum opulus L.) аccessions of the L.P. Symyrenko pomology experimental station of the institute of horticulture in the forest-steppe of Ukraine
Authors: Tyhyi Т.I. 
Published: May 2021

Aim. To determine economic and biological indicators (yield, average weight, palatability) of Viburnum opulus accessions under the conditions of the central forest-steppe of Ukraine.
Results and Discussion. V. opulus accessions were studied at the L.P. Symyrenko Experimental Station of Pomology of the Institute of Horticulture of NAAS in 2015-2019. Five cultivars were studied: Koralova, Velykoplidna, Rubinova, Ukrainochka, and Bahriaana. In addition, 21 elite hybrid forms, which had been planted in plots of 4 m x1.5 m in 1998, were investigated. The number of recorded plants per plot was 15 in 3 replications.	Measurements and monitoring were performed according to conventional methods. Multi-year breeding resulted in the following cranberry tree cultivars: Koralova, Velykoplidna, Rubinova, Ukrainochka, and Bahriana. Pomological characteristics of the cultivars are given for basic economic and biological features under the conditions of the forest-steppe of Ukraine. The yield capacity is the main criterion in economic evaluation of V. opulus. It to a large extent depends on characteristics of a cultivar, soil and climatic factors, and farming techniques. The fruit size and palatability are major components of the performance determining the fruit quality. Large and uniform berries are more attractive both as fresh and as frozen products. In 2015-2019, the V. opulus yield ranged 6.52 to 9.37 kg per bush and 10.9 to 15.6 tons per hectare. The average berry weight was 0.8 - 1.25 g. Cultivar Bahriana and hybrid form Ch-19500 were the most productive: 9.37 kg and 9.19 kg per bush, respectively. Velykoplidna, Rubinova and Bahriana were distinguished due to the average berry weight: 1.25 g, 1.2 g and 1.2 g, respectively. We built up a working collection of V. opulus accessions by yield capacity and quality. The collection comprises 20 cultivars. All the cultivars are of local origin. The collection is formed by the following traits: yield level, berry size, berry shape, berry after colour, berry hardness, palatability, and the berry number per corymb.
Conclusions. The 2015-2019 studies showed that the highest yields were obtained from Bahriana (15.6 t/ha), elite hybrid form Ch-19500 (15.3 t/ha) and elite hybrid form P-19503 (15 t/ha); the highest fruit weight was recorded in Velykoplidna (1.25 g), Rubinova (1.2 g), Bahriana (1.2 g), Ukrainochka (1.15 g), and elite hybrid form P-19503 (1.16 g); the best palatability scores were intrinsic to Koralova (8.5 points), Rubinova (8.5), Ukrainochka (8.3), Bahriana (8.3), elite hybrid form K-19501 (8.3).
Processing cataphors: Active antecedent search is persistent
Authors: Giskes Anna , Kush Dave 
Published: May 2021

AbstractCataphors precede their antecedents, so they cannot be fully interpreted until those antecedents are encountered. Some researchers propose that cataphors trigger an active search during incremental processing in which the parser predictively posits potential antecedents in upcoming syntactic positions (Kazanina et al., Journal of Memory and Language, 56[3], 384–409, 2007). One characteristic of active search is that it is persistent: If a prediction is disconfirmed in an earlier position, the parser should iteratively search later positions until the predicted element is found. Previous research has assumed, but not established, that antecedent search is persistent. In four experiments in English and Norwegian, we test this hypothesis. Two sentence completion experiments show a strong off-line preference for coreference between a fronted cataphor and the first available argument position (the main subject). When the main subject cannot be the antecedent, participants posit the antecedent in the next closest position: object position. Two self-paced reading studies demonstrate that comprehenders actively expect the antecedent of a fronted cataphor to appear in the main clause subject position, and then successively in object position if the subject does not match the cataphor in gender. Our results therefore support the claim that antecedent search is active and persistent.

Se concluyó que el tabaco y el alcohol son las sustancias de mayor prevalencia, la mayor parte de ellos presentan una alta resiliencia, se observa que no existe relación significativa entre las mismas, salvo entre funcionalidad psicosocial y resiliencia.
Real-time Likelihood-free Inference of Roman Binary Microlensing Events with Amortized Neural Posterior Estimation

Published: May 2021

Abstract
Fast and automated inference of binary-lens, single-source (2L1S) microlensing events with sampling-based Bayesian algorithms (e.g., Markov Chain Monte Carlo, MCMC) is challenged on two fronts: the high computational cost of likelihood evaluations with microlensing simulation codes, and a pathological parameter space where the negative-log-likelihood surface can contain a multitude of local minima that are narrow and deep. Analysis of 2L1S events usually involves grid searches over some parameters to locate approximate solutions as a prerequisite to posterior sampling, an expensive process that often requires human-in-the-loop domain expertise. As the next-generation, space-based microlensing survey with the Roman Space Telescope is expected to yield thousands of binary microlensing events, a new fast and automated method is desirable. Here, we present a likelihood-free inference approach named amortized neural posterior estimation, where a neural density estimator (NDE) learns a surrogate posterior

as an observation-parameterized conditional probability distribution, from pre-computed simulations over the full prior space. Trained on 291,012 simulated Roman-like 2L1S simulations, the NDE produces accurate and precise posteriors within seconds for any observation within the prior support without requiring a domain expert in the loop, thus allowing for real-time and automated inference. We show that the NDE also captures expected posterior degeneracies. The NDE posterior could then be refined into the exact posterior with a downstream MCMC sampler with minimal burn-in steps.
Properties of Highly Rotationally Excited H2 in Photodissociation Regions

Published: May 2021

Abstract
Molecular hydrogen (H2) is the dominant molecular species in the vast majority of interstellar environments and it plays a crucial role as a radiative coolant. In photodissociation regions (PDRs), it is one of the primary emitters in the near- to mid-infrared, which is due to lines originating from highly excited levels. The sparseness of H2 collisional data for rotational levels J ≥ 9, particularly for H2–H2 collisions, has limited nonlocal thermal equilibrium (NLTE) studies in ultraviolet-irradiated regions. Utilizing new calculations for para- and ortho-H2 high rotational collisional rate coefficients colliding with H2 (up to the maximum value for v = 0: J = 31), existing data for H2–H and H2–He collisions, and approximate scaling relations for missing collisional data, we investigate the excitation properties of H2 in a range of astrophysical environments, with the focus on PDRs (including benchmark PDR models and the Orion Bar). In these NLTE models, H2 emission is illustrated and shown as a diagnostic for physical conditions, such as temperature and density. Furthermore, we demonstrated the effect of updates in the collisional rates on the modeling results of H2 excitation. The resulting data sets of H2 collisional data should find wide application to other molecular environments.

Abstract
A classical paradox in high-mass star formation is that powerful radiation pressure can halt accretion, preventing further growth of a central star. Disk accretion has been proposed to solve this problem, but the disks and the accretion process in high-mass star formation are poorly understood. We executed high-resolution (R = 35,000–70,000) iSHELL spectroscopy in K-band for 11 high-mass protostars. Br-γ emission was observed toward eight sources, and the line profiles for most of these sources are similar to those of low-mass PMS stars. Using an empirical relationship between the Br-γ and accretion luminosities, we tentatively estimate disk accretion rates ranging from ≲10−8 and ∼10−4
M
⊙ yr−1. These low-mass-accretion rates suggest that high-mass protostars gain more mass via episodic accretion as proposed for low-mass protostars. Given the detection limits, CO overtone emission (v = 2−0 and 3−1), likely associated with the inner disk region (r ≪ 100 au), was found toward two sources. This low-detection rate compared with Br-γ emission is consistent with previous observations. Ten out of the 11 sources show absorption at the v = 0–2 R(7) − R(14) CO R-branch. Most of them are either blueshifted or redshifted, indicating that the absorption is associated with an outflow or an inflow with a velocity of up to ∼50 km s−1. Our analysis indicates that the absorption layer is well thermalized (and therefore

cm−3) at a single temperature of typically 100–200 K, and located within 200–600 au of the star.

Abstract
Using a sample of 96,201 primary red clump stars selected from the LAMOST and Gaia surveys, we investigate the stellar structure of the Galactic disk. The sample stars show two separated sequences of high-[α/Fe] and low-[α/Fe] in the [α/Fe]–[Fe/H] plane. We divide the sample stars into five mono-abundance populations (MAPs) with different ranges of [α/Fe] and [Fe/H], named as the high-[α/Fe], high-[α/Fe] and high-[Fe/H], low-[Fe/H], solar, high-[Fe/H] MAPs, respectively. We present the stellar number density distributions in the R–Z plane, and the scale heights and scale lengths of the individual MAPs by fitting their vertical and radial density profiles. The vertical profiles, the variation trend of scale height with the Galactocentric radius, indicate that there is a clear disk flare in the outer disk both for the low-[α/Fe] and the high-[α/Fe] MAPs. While the radial surface-density profiles show a peak radius of 7 kpc and 8 kpc for the high-[α/Fe] and low-[α/Fe] MAPs, respectively. We also investigate the correlation between the mean rotation velocity and metallicity of the individual MAPs, and find that the mean rotation velocities are well separated and show different trends between the high-[α/Fe] and the low-[α/Fe] MAPs. Finally, we discuss the character of the high-[α/Fe] and high-[Fe/H] MAP and find that it is more similar to the high-[α/Fe] MAP either in the radial and vertical density profiles or in the rotation velocity.
