Published: May 2023

AbstractSystematic reviews and meta-analysis are the cornerstones of evidence-based decision making and priority setting. However, traditional systematic reviews are time and labour intensive, limiting their feasibility to comprehensively evaluate the latest evidence in research-intensive areas. Recent developments in automation, machine learning and systematic review technologies have enabled efficiency gains. Building upon these advances, we developed Systematic Online Living Evidence Summaries (SOLES) to accelerate evidence synthesis. In this approach, we integrate automated processes to continuously gather, synthesise and summarise all existing evidence from a research domain, and report the resulting current curated content as interrogatable databases via interactive web applications. SOLES can benefit various stakeholders by (i) providing a systematic overview of current evidence to identify knowledge gaps, (ii) providing an accelerated starting point for a more detailed systematic review, and (iii) facilitating collaboration and coordination in evidence synthesis.
Cooperative hybrid beamforming design in Multi‐UAV MmWave MIMO systems

Published: May 2023

AbstractDue to the limitation of mobility and cost, it is inappropriate to utilize ground base station (GBS) to provide service in emergency scenarios or harsh environments. Unmanned aerial vehicle (UAV) is considered as a feasible way to solve the problem. Millimetre wave communication and UAV can be used together to offer wireless communications flexibly and rapidly for target area. However, fuselage jittering and energy supply would affect the quality and reliability of UAV communication seriously. To overcome the weakness of UAV, the authors prefer to use multiple UAVs to provide wireless communication service simultaneously. This paper investigates the design of hybrid beamforming in the scenarios including multiple UAVs and one end user. Cooperation strategy and alternating optimization method are applied in this design. The distributed UAV base stations are regarded as an entirety and the reference beamforming scheme obtained. Then, the beamforming problem for each UAV is formulated. Moreover, residual error minimization (REM) algorithm is proposed to find the solution of hybrid beamformers at UAV side. Finally, the beamformer of the receiver is optimized with the assist of effective channel, which includes the gain of both channel and beamformers of the transmitters. Simulation results show that the proposed algorithm can achieve near‐optimal spectral efficiency in different scenarios.
The optimal triangulation method is not really optimal

AbstractTriangulation refers to the problem of finding a 3D point from its 2D projections on multiple images taken at different camera poses. For solving this problem, it is a common practice to use the so‐called optimal triangulation method. But, the method can be optimal only if we assume no uncertainty in the camera parameters. In this paper, an extensive comparison between various existing methods for the calibrated cameras is performed, in which different poses are considered. Furthermore, uncertainty sensitivity analysis is conducted for extrinsic parameters of cameras. The results show that the optimal triangulation method is actually not the best choice when there is uncertainty in extrinsic parameters. Interestingly, it can be observed that the simple midpoint method works equally well or outperforms the optimal triangulation and many other methods. Apart from its high performance, the midpoint method has a simple closed form solution for multiple views while the optimal triangulation method is hard to be used for more than two views. Therefore, in contrast to the common practice, we argue that the simple midpoint method can be a good choice in the structure‐from‐motion process where there is uncertainty in extrinsic camera parameters.

Published: May 2023

Context. Radio astronomy is currently thriving with new large ground-based radio telescopes coming online in preparation for the upcoming Square Kilometre Array (SKA). Facilities like LOFAR, MeerKAT/SKA, ASKAP/SKA, and the future SKA-LOW bring tremendous sensitivity in time and frequency, improved angular resolution, and also high-rate data streams that need to be processed. They enable advanced studies of radio transients, volatile by nature, that can be detected or missed in the data. These transients are markers of high-energy accelerations of electrons and manifest in a wide range of temporal scales (e.g., from milliseconds for pulsars or fast radio bursts to several hours or days for accreting systems). Usually studied with dynamic spectroscopy of time series analysis, there is a motivation to search for such sources in large interferometric datasets. This requires efficient and robust signal reconstruction algorithms.Aims. To correctly account for the temporal dependency of the data, we improve the classical image deconvolution inverse problem by adding the temporal dependency in the reconstruction problem, and we propose a solution based on deep learning.Methods. We introduce two novel neural network architectures that can do both spatial and temporal modeling of the data and the instrumental response. Then, we simulate representative time-dependent image cubes of point source distributions and realistic telescope pointings of MeerKAT to generate toy models to build the training, validation, and test datasets. Finally, based on the test data, we evaluate the source profile reconstruction performance of the proposed methods and classical image deconvolution algorithm CLEAN applied frame-by-frame.Results. In the presence of increasing noise level in data frame, the proposed methods display a high level of robustness compared to frame-by-frame imaging with CLEAN. The deconvolved image cubes bring a factor of 3 improvement in fidelity of the recovered temporal profiles and a factor of 2 improvement in background denoising.Conclusions. The proposed neural networks are not iterative and can benefit from efficient GPU-based architectures. Consequently, they could unlock the development of real-time data processing at the initial cost of learning the behavior of the telescope. Radio observatories are performing sky surveys to produce deep images in ever larger fields of view, increasing the transient source access window both spatially and temporally. Our method can effectively capture the temporal structures that are present in such survey data.
WHIM-hunting through cross-correlations between optical and SZ effect data in the Virgo cluster filaments
Authors: Erciyes Cagri , Basu Kaustuv , Kim Suk , Rey Soo-Chang 
Published: May 2023

Context. The physical state of most of the baryonic matter in the local universe is unknown, commonly referred to as the “missing baryon problem”. It has been theorized that at least half of these missing baryons are in a warm-hot, low-density phase, outside of the virialized dark-matter halos.
Aims. We attempted to find the signature of this warm-hot intergalactic medium (WHIM) phase in the filaments of the nearby Virgo cluster by using optical and Sunyaev-Zeldovich effect data.
Methods. Specifically, we used a filament-galaxy catalog created from the HyperLeda database and an all-sky Compton-y map extracted from the Planck satellite data for two-dimensional cross-correlation analysis by applying a spherical harmonics transform. The significance test is based on the null-test simulations, which exploits advanced cut-sky analysis tools for a proper map reconstruction. To place upper limits on the WHIM density in the Virgo filaments, realistic baryonic density modeling within the cosmic filaments was done based on state-of-the-art hydro-simulations, within the signal-boosting routine.
Results. The cross-correlation signal is found to be too dim compared to the noise level in the Plancky-map. At a 3 σ confidence level, the upper limit on volume-average WHIM density turns out to be ⟨ ne ⟩< 4 × 10−4 cm−3, which is indeed consistent with the WHIM parameter space, as predicted from simulations.

Abstract
Introduction Endometriosis significantly reduces patientsʼ quality of life and is additionally a burden on healthcare and social security systems. There are currently no quality
indicators for the treatment of endometriosis. The care of patients with endometriosis must be considered inadequate. QS ENDO aims to record the quality of care available in the DACH region
and to introduce quality indicators for the diagnosis and treatment of endometriosis as part of providing quality assurance in endometriosis care. The first phase, QS ENDO Real, recorded the
reality of current care using a questionnaire. The second phase, QS ENDO Pilot, investigated the treatment of 435 patients who underwent surgical treatment within a defined one month period
in certified endometriosis centers.
Material and Methods An online tool was used to gather information about 9 points which covered both prior patient history and the process of clinical diagnosis. Surgery reports were
reviewed to obtain information about the surgical approach, the investigated sites, findings of any histological examinations, the use of classification systems, and information about
resection status.
Results 85.3% of patients were asked all 4 questions about their prior medical history. All 5 diagnostic steps were carried out in 34.5% of patients. The 3 areas needed to describe
potential sites of disease were recorded in 67.1% of patients. Samples for histological examination were taken in 84.1% of patients. The endometriosis stage was classified in 94.7% of
surgeries. A combination of the rASRM and the ENZIAN classifications, which is needed for complex cases, was used in 46.1% of patients. Complete resection was achieved in 81.6% of surgical
procedures.
Conclusion For the first time, the quality of care in certified endometriosis centers has been recorded using QS ENDO Pilot. Despite the high certification standards, a substantial
number of required indicators were omitted.

Of particular interest are the purely organic CP-RTPs, as they offer excellent biocompatibility, versatile tunability, and cost-effectiveness. These materials show promising applications in fields including biological imaging, photodiodes, intelligent sensing, information storage, and three-dimensional displays. To deepen our understanding of the luminescence mechanism and broaden the envisioned scope, herein, we summarize them based on chirality character, including point, axial, planar, and other chiral systems.

Abstract
Objective In this study, we aimed to evaluate the efficacy and safety of combination therapy, consisting of intravenous immunoglobulin (IVIg) and corticosteroids, in comparison to respective monotherapies in the treatment of relapsed immune thrombocytopenia (ITP) in adults.
Methods A retrospective analysis of clinical data was conducted on 205 adult patients with relapsed ITP who received first-line combination therapy or monotherapy in multiple centers across China from January 2010 to December 2022. The study evaluated the patients' clinical characteristics, efficacy, and safety.
Results We found that the proportion of patients with platelet counts in complete response was significantly higher in the combination group (71.83%) compared with the IVIg group (43.48%) and the corticosteroids group (23.08%). The mean PLTmax in the combination group (178 × 109/L) was significantly higher than that in the IVIg group (109 × 109/L) and the corticosteroids group (76 × 109/L). Additionally, the average time for platelet counts to reach 30 × 109/L, 50 × 109/L, and 100 × 109/L in the combination group was significantly shorter than in the monotherapy groups. The proportion curves for reaching these platelet counts during treatment were also significantly different from those in the monotherapy groups. However, there were no significant differences in the effective rate, clinical characteristics, and adverse events among the three groups.
Conclusion We concluded that combining IVIg and corticosteroids was a more effective and faster treatment for relapsed ITP in adults than using either therapy alone. The findings of this study provided clinical evidence and reference for the use of first-line combination therapy in the treatment of relapsed ITP in adults.

The accurate and precise determination of the compositions of silicate glasses formed from melts containing volatile components H2O and CO2 recovered from high-pressure, high-temperature experiments is essential to our understanding of geodynamic processes taking place within the planet. Silicate melts are often difficult to analyze chemically because the formation of quench crystals and overgrowths on silicate phases is rapid and widespread upon quenching of experiments, preventing the formation of glasses in low-SiO2 and volatile-rich compositions. Here, we present experiments conducted in a novel rapid quench piston cylinder apparatus on a series of partially molten low-silica alkaline rock compositions (lamproite, basanite, and calk-alkaline basalt) with a range of water contents between 3.5 and 10 wt %. Quench modification of the volatile-bearing silicate glasses is significantly reduced compared to those produced in older piston cylinder apparatuses. The recovered glasses are almost completely free of quench modification and facilitate the determination of precise chemical compositions. We illustrate significantly improved quench textures and provide an analytical protocol that recovers accurate chemical compositions from both poorly quenched and well-quenched silicate glasses.
Simulation study on the influence of metal contact and MOS interface trap states on the electrical characteristics of SiC IGBT

Published: May 2023

A 13 kV class n-channel 4H–SiC trench gate insulated gate bipolar transistor (IGBT) structure is designed based on Silvaco TCAD device simulator tool. The influence of metal/SiC and SiC MOS interface trap states on the static and dynamic characteristics of SiC IGBT devices are systematically studied. It is found that the electrical properties of SiC IGBTs are insensitive to the donor or acceptor traps at the interface of metal/SiC and the donor traps at the SiC/SiO2 interface. However, the acceptor traps at the SiC/SiO2 interface affect the electrical properties of SiC IGBTs greatly. When the acceptor trap density at the SiC/SiO2 interface (Dita) is up to the level of 1012 cm−2·eV−1, the turn-on voltage drop (VCEON) is increased gradually with the augmentation of Dita. The breakdown voltage (VBR) of the device is increased slightly. Further study of the device’s turn-off characteristics shows that the turn-off loss (EOFF) is decreased with the increase in Dita but a large tail current is formed. The mechanism may be that when the electrons are injected from the N+ source region into the N− drift region, the SiC/SiO2 interfacial acceptor traps at the side wall of trench gate capture a large number of electrons. As a result, the minority carrier concentration is decreased, and the conductance modulation effect on the N− drift region is weakened.
Investigations of point defect and interface in cg-N under high-pressure

Published: May 2023

The properties of cg-N with point defects and an interface are investigated based on the first-principles method. Our results show that at 0 GPa, the stability of cavities depends on their size. A smaller cavity has higher stability than the larger case. The decomposition of N2 molecules mainly occurs on the (110) surface of the cavity. However, the decomposition process will be suppressed by applying high-pressure. For the interface constructed by (110) surfaces, N2 molecules will be released at low pressure, and polymerization of N2 molecules with surfaces is triggered by loading pressures of 80–100 Gpa, giving rise to a stable polymerized interface, which is also stable after decreasing the pressure to 0 GPa. The results indicate that the existence of polymeric nitrogen networks can enhance the polymerization of N2 molecules at low-temperature.
Elevating the energy efficiency for the power-to-ammonia conversion: Role of oxygen evolution reaction kinetics
Authors: Biswas Ashmita , Dey Ramendra Sundar 
Published: May 2023

Electrochemical nitrogen reduction reaction (NRR) is imperatively countered with the oxygen evolution reaction (OER) on a conventional Pt counter electrode. Upon focusing on the development of suitable cathode catalysts, it is usually overseen that OER on Pt seeks a significant energy input to overcome the slow reaction kinetics, regardless of the efficiency of the NRR catalyst. Here, we unveil an out-of-the-box concept with state-of-the-art catalysts that, on pursuing OER with RuO2 in KOH, the NRR process reinforces thermodynamically. In this work, it has been shown how both the electrode and electrolyte simultaneously help to elevate a reaction mechanism in terms of Gibbs’ energy and equilibrium constant. As a proof of concept, we assembled RuO2 with an NRR catalyst, iron phthalocyanine (FePc), in an electrolyzer, preferably in a two-electrode setup, where the catholyte consisted of 0.5M NaBF4. This system achieved selective cathodic conversion of N2 to NH3 with 67.6% Faradaic efficiency at 0.0 V (vs reversible hydrogen electrode) and simultaneous anodic water oxidation to O2 with a high electricity-to-chemical energy conversion efficiency of 46.7%. The electrolyzer forecasted a full cell voltage of 2.04 V, which demands only 603 mV overpotential to attain 0.5 mA current to drive forward the chemical equilibrium of the overall cell reaction. This study not only emphasized the importance of electrode–electrolyte improvisation but also provided a wider outlook in terms of different thermodynamic parameters to be considered to determine the efficiency of the overall NRR coupled OER process.
