Metabolic Syndrome and Clinical Outcomes of Patients with Gastric
Cancer: A Meta-Analysis
Authors: Huang Zhiyang , Zhou Jianwei , Chen Long , Zhang Yibing 
Published: April 2023

AbstractMetabolic syndrome (MetS) is suggested to participate in the pathogenesis and
progress of some cancers via inducing low-grade systemic inflammation. However,
the influence of MetS on patients with gastric cancer (GC) remains not fully
determined. A systematic review and meta-analysis was therefore performed to
evaluate the influence of MetS on clinical outcomes of patients with GC. A
search of PubMed, Embase, Web of Science, Wanfang, and CNKI retrieved relevant
cohort studies from the inception of the databases to October 11, 2022. We
pooled the results using a random-effects model that incorporates heterogeneity.
In the meta-analysis, 6649 patients with GC were included, and all of them
received gastrectomy. A total of 1248 (18.8%) patients had MetS at
baseline. Pooled results showed that MetS was associated with higher risks of
postoperative complications [risk ratio (RR): 2.41, 95% confidence
interval (CI): 1.85 to 3.14, p<0.001; I2=55%], overall
mortality (RR: 1.73, 95% CI: 1.85 to 3.14, p<0.001;
I2=77%), and recurrence of GC (RR: 2.00, 95% CI: 1.10 to
3.63, p=0.02; I2=39%). Subgroup analyses showed similar
results in prospective and retrospective cohort studies and in studies with MetS
diagnosed with the Chinese Diabetes Society criteria and the National
Cholesterol Education Program Adult Treatment Panel III criteria (p for subgroup
difference all>0.05). In patients with GC after gastrectomy, MetS may be
a predictor of high incidence of postoperative complications, cancer recurrence,
and overall mortality.

Abstract
Background and study aims An important therapeutic aim in ulcerative colitis (UC) is endoscopic remission. Although an endoscopic score with white light imaging (WLI) is mainly used to evaluate endoscopic findings, the usefulness of linked color imaging (LCI) has been reported. We evaluated the relationship between LCI and histopathological findings and attempted to establish a new LCI endoscopic evaluation index for UC.
Patients and methods This study was conducted at Kyorin University, Kyoto Prefectural University, and Fukuoka University Chikushi Hospital. Ninety-two patients with a Mayo endoscopic subscore (MES) ≤ 1 who underwent colonoscopy for UC in clinical remission were included. LCI index was defined as redness (R) (Grade 0–2), area of inflammation (A) (Grade 0–3), and lymphoid follicles (L) (Grade 0–3). Histological healing was defined as Geboes score < 2B.1. Endoscopic and histopathological scores were determined by central judgment.
Results In 92 patients, 85 biopsies from the sigmoid colon and 84 biopsies from the rectum (total 169 biopsies) were evaluated. There were 22, 117, and 30 cases of Grades 0, 1, and 2, respectively in LCI index-R; 113, 34, 17, and five cases of Grades 0, 1, 2, and 3, respectively, in LCI index-A; and 124, 27, 14, and four cases of Grades 0, 1, 2, and 3, respectively, in LCI index-L. Histological healing was achieved in 84.0 % of the cases (142 of 169), and there were significant associations with histological healing or non-healing in LCI index-R (P = 0.013) and A (P = 0.0014).
Conclusions A new LCI index is useful for predicting histological healing in UC patients with MES ≤ 1 and clinical remission.

A Rare Patient with Hereditary Spastic Paraparesis with Parkinsonism
Authors: Onder Halil , Comoglu Selcuk 
Published: April 2023

AbstractHerein, we present a rare patient with hereditary spastic paraparesis (HSP) in whom significant parkinsonism was involved in the clinic. Besides, the dopamine transport single-photon emission computed tomography scan also showed decreased tracer uptake in the bilateral striatum. Via the presentation of this patient, we discuss the parkinsonian findings in patients with HSP. We think that the observations of dopaminergic neuron vulnerability in HSP patients raise the possibility that degeneration of central dopaminergic neurons may contribute to the phenotype of HSP. The documentation of these rare variants will aid to understand the unknown pathophysiology of the disease course.

Published: April 2023

We report the continuous Si doping in β-Ga2O3 epitaxial films grown by plasma-assisted molecular beam epitaxy through the use of a valved effusion cell for the Si source. Secondary ion mass spectroscopy results exhibit that the Si doping profiles in β-Ga2O3 are flat and have sharp turn-on/off depth profiles. The Si doping concentration was able to be controlled by either varying the cell temperatures or changing the aperture of the valve of the Si effusion cell. High crystal quality and smooth surface morphologies were confirmed on Si-doped β-Ga2O3 epitaxial films grown on (010) and (001) substrates. The electronic properties of Si-doped (001) β-Ga2O3 epitaxial film showed an electron mobility of 67 cm2/Vs at the Hall concentration of 3 × 1018 cm−3.

We report the use of suboxide molecular-beam epitaxy (S-MBE) to grow β-Ga2O3 at a growth rate of ∼1 µm/h with control of the silicon doping concentration from 5 × 1016 to 1019 cm−3. In S-MBE, pre-oxidized gallium in the form of a molecular beam that is 99.98% Ga2O, i.e., gallium suboxide, is supplied. Directly supplying Ga2O to the growth surface bypasses the rate-limiting first step of the two-step reaction mechanism involved in the growth of β-Ga2O3 by conventional MBE. As a result, a growth rate of ∼1 µm/h is readily achieved at a relatively low growth temperature (Tsub ≈ 525 °C), resulting in films with high structural perfection and smooth surfaces (rms roughness of &lt;2 nm on ∼1 µm thick films). Silicon-containing oxide sources (SiO and SiO2) producing an SiO suboxide molecular beam are used to dope the β-Ga2O3 layers. Temperature-dependent Hall effect measurements on a 1 µm thick film with a mobile carrier concentration of 2.7 × 1017 cm−3 reveal a room-temperature mobility of 124 cm2 V−1 s−1 that increases to 627 cm2 V−1 s−1 at 76 K; the silicon dopants are found to exhibit an activation energy of 27 meV. We also demonstrate working metal–semiconductor field-effect transistors made from these silicon-doped β-Ga2O3 films grown by S-MBE at growth rates of ∼1 µm/h.

Published: April 2023

Many applications that could benefit from the underwater optical wireless communication technique face challenges in using this technology due to the substantial, varying attenuation that affects optical signal transmission through waterbodies. This research demonstrated that convolutional neural networks (CNNs) could readily address these problems. A modified CNN model was proposed to recover the original data of a non-return to zero on–off keying modulated signal transmitted optically through a tank full of Gulf seawater. A comparison between the proposed CNN model and a conventional fixed-threshold decoder (FTD) demonstrates the excellent performance of the proposed CNN model, which improved the bit error ratio (BER), signal-to-noise ratio (SNR), and effective channel length. The BER of the optical signals that are transmitted at powers of 24, 26, and 27 dBm and a bit rate of 10 Mbit/s at a distance of 3 m from the transmitter when FTD is used is 7.826 × 10−7, 5.049 × 10−8, and 8.38 × 10−10, respectively. When the CNN decoder is used at the same distance and powers, the BER is 6.23 × 10−14, 1.44 × 10−16, and 2.69 × 10−18, respectively. In conclusion, the BER decreased by about seven orders of magnitude, the effective channel length increased by four times, and the SNR decreased by about 20 dB. The simplicity of the proposed CNN decoder is independent of the prior knowledge of the channel conditions. Furthermore, the magnificent obtained results make the proposed CNN decoder an ideal substitute for ordinary underwater optical wireless communication decoders.

Context L-citrulline (L-Cit) does not degrade in the rumen and has the ability to form peptide bonds in the body; however, it does not participate in protein synthesis. Aims This study aimed to evaluate the effects of L-Cit on the reproductive performance of Hu ewes. Methods In total, 30 ewes were randomly categorised into five groups. The control group was fed with a basic diet, whereas the Experimental Groups I, II, III, and IV were provided feed supplemented with 5, 10, 15, and 20 g/day of L-Cit respectively. Blood samples of ewes were collected 4 h after feeding on Day 21 of the experiment and before feeding on Day 30. The optimal supplementary feeding dose was selected on the basis of blood biochemical indexes. Overall, ninety 2-year-old ewes were classified into two groups. The control group was fed with a basic diet and the experimental group was fed with a diet supplemented with 10 g/day of L-Cit. After 30 days of supplementary feeding, reproductive performance of ewes was determined. Key results The plasma concentrations of Cit, ornithine, and arginine in ewes increased linearly with an increase in the level of L-Cit supplementation. The plasma concentrations of gonadotropin-releasing hormone, luteinising hormone, and follicle-stimulating hormone in the experimental group increased significantly compared with those in the control group. The plasma total antioxidant capacity and catalase, superoxide dismutase, and glutathione peroxidase in the experimental group were significantly higher than those in the control group, whereas the concentrations of malondialdehyde in all experimental groups were significantly lower than those in the control group. The conception, lambing, and double lambing rates of the experimental group were increased by 28.76%, 15.90%, and 40.21% respectively. Conclusions Supplementation with different doses of L-Cit can improve the concentrations of some plasma amino acids and reproductive hormones as well as antioxidant capacity of ewes. Supplementary feeding with 10 g/day of L-Cit could increase the lambing and double lambing rates of ewes. Implication L-Cit can improve the reproductive performance of ewes.
Rhetorical strategies for the construction of a corporate identity

Published: April 2023

AbstractUsing Huawei annual reports as data sources, this study examines rhetorical strategies in business discourse for the construction of corporate identity. A socio-pragmatic framework is proposed for analysing such strategies, incorporating a textual analysis of rhetorical strategies, a discourse analysis of pragmatic functions and discursive tendencies, and a social analysis of the construction of corporate identity. The research concludes that, among other strategies, allusion and reference demonstrate the discursive tendency of commodification, while parody and metaphor highlight the discursive tendency of democratisation. In terms of the constructive functions, allusion, reference, parody, and metaphor are used to construct the commerciality, legitimacy, approachability, and entrepreneurship of an enterprise, respectively. This study highlights the importance of rhetorical strategies for the construction of corporate identity and the necessity for annual report writers to employ rhetorical strategies for better corporate communication.
Homogeneous dielectric barrier discharge in CO2

Published: April 2023

Abstract
This study investigates dielectric barrier discharges generated in CO2 at atmospheric pressure. According to the literature, under these conditions, discharges usually work in the filamentary regime. On the contrary, the experimental results reported in the present study demonstrate for the very first time that it is also possible to obtain a diffuse CO2 discharge under these conditions. The diffuse regime appears to be related to a memory effect mechanism occurring at the dielectric surface. Both the filamentary and diffuse regimes were compared in this work based on electrical measurements coupled with intensified charged coupled device (iCCD) imaging and optical emission spectroscopy. The clear difference between both regimes is discussed.

Published: April 2023

Abstract
Liquid Nitrogen (LN2) has good insulation and arc-quenching properties. It can minimize the switchgear losses to a low level due to its cryogenic nature. Optical observation of LN2-arcs is very important for the future design of the Liquid Nitrogen Insulated metal enclosed Switchgear (LNIS). It would help in determining the spacers sizing, and the clearance distances between the LN2 Switch and the other equipment inside the LNIS system. Until now, no one has ever done the optical analysis of high-luminance arcs in the LN2 environment. The objective of this work was to determine the shape, size and current-density effects of arc plasmas in LN2. One type of electrode geometry and three types of electrode materials were used to study the LN2-arc characteristics. The influence of cryogenic environment on the arcs were thoroughly studied. Results showed that the arcs in LN2 have a direct relationship with the applied voltages, interrupting currents and the magnetic fields. The higher the interrupting current, the larger is the size of the arc. It was also observed that different electrodes materials have different shapes of arc plasmas. Magnetic fields can significantly influence the LN2-arc by increasing its size, patterning its shape and reducing its arcing time.

Published: April 2023

Abstract
A flexible transparent composite metamaterial structure compatible with microwave absorption in the radar band and low emissivity in the infrared is proposed. The radar wave absorber and infrared shield layers, which can control microwave absorption and infrared emission respectively, are designed and fabricated on a transparent substrate using indium tin oxide material. It achieves 90% absorption over a wide frequency range of 2.12–15.87 GHz, wide incidence angle stability over a range of 50° and maintains absorption of more than 90% over a polarisation range of 70°. The emissivity of the metamaterial structure in the infrared band is approximately 0.25. The current distribution of the structure is analysed and the equivalent circuit model is developed to reveal the absorption mechanism. The test results are in general agreement with the simulation results, and the design has application value for multi-spectral stealth and transparent electromagnetic shielding.

Measurements have shown that capacitance and conductivity are highly frequency dependent. At low frequencies, the surface states have increased, but as the frequency increased, the values became too low to pin the Fermi level.

Abstract
Recent advancements in high-dose-rate brachytherapy have led to remarkable clinical outcomes. However, these new developments can cause unknown uncertainties with respect to actual dose delivery, which are yet to be clarified. Therefore, an accurate dose verification system is required. Currently, procedures for image-guided adaptive brachytherapy are constrained by the following limitations: (1) patient transportation between the treatment room and CT/MR (computerized tomography/magnetic resonance) imaging room can displace the application position, (2) the physiological and anatomical changes in the patient’s body cannot be observed during the treatment schedule involving 3–10 fraction, and (3) the movement of the radioactive source inside the body is impossible to track. This study proposes a concept of an integrated online imaging system, which is based on integrated CT and single-photon emission computed tomography (SPECT), namely, the C-arm CT/SPECT system—a combination of a C-arm fluoroscopic x-ray imaging system and an attachable parallel-hole collimator over the imaging detector. The Geant4 software is used to simulate the application of the C-arm CT/SPECT system for 192Ir-based brachytherapy in a pelvis-like phantom. To improve the image quality of C-arm CT/SPECT acquired with limited-angle information, we utilized an adaptive-steepest-descent-projection-onto-convex-sets framework that incorporates additional prior information for the proposed system. Furthermore, we confirmed that SPECT images can be obtained using a parallel-hole collimator and estimated the dose distribution in the medium and CT/SPECT fusion imaging during treatment. This strategy is expected to be effectively implemented in online image-guided adaptive brachytherapy and patient-dose verification.

Abstract
For the High-Luminosity upgrade of the LHC, the current ATLAS inner detector will be replaced with a new silicon charged-particle tracker, the ITk, which consists of the ITk Pixel and the ITk Strip subdetector. The high voltage multiplexing (HV-Mux) GaNFETs are radiation-tolerant transistors that permit switching off high voltage to malfunctioning sensors on the ITk Strip modules. To ensure the reliability of the GaNFETs in the high radiation environment expected at the HL-LHC, a sample of the production batch was exposed to gamma radiation. The GaNFETs were characterized pre-irradiation and post-irradiation, and monitored during irradiation.
Comment on ‘The central role of forests in the 2021 European floods’
Authors: Staal Arie , Koren Gerbrand 
Published: April 2023

Abstract
In July 2021, parts of Germany and Belgium were hit by severe floods. In ‘The central role of forests in the 2021 European floods’, published in Environmental Research Letters (2022 Environ. Res. Lett.
17 064053), Insua-Costa et al reported that ‘moisture from North American forests was a more important source [of the rainfall contributing to the event] than evaporation over nearby seas’. This suggests that the event was (partly) caused by anomalous contributions from North America. In this comment, we show that this is a misleading interpretation, as: (1) the relative contribution of North American land was below average for the time of year; and (2) rather, the anomalous moisture that contributed to the floods originated mainly from European land. However, consistent with Insua-Costa et al, we find no enhanced evaporation from Europe prior to the event and we therefore conclude that there is a lack of evidence for the ‘central role’ of forests in the 2021 European floods.
Investigation of the effect of welding and rotational speed on strain and temperature during friction stir welding of AA5083 and AA7075 using the CEL approach
Authors: Akbari Mostafa , Asiabaraki Hossein Rahimi , Aliha MRM 
Published: April 2023

Abstract
In this study, the friction stir welding between AA5083 and AA7075 is modeled using numerical methods, and the role of parameters affecting the process, such as welding speed and rotation speed on material flow, temperature, and strain, is studied. The temperature, strain, and material mixing were analyzed while welding AA7075 to AA5083 alloys using a Coupled Eulerian-Lagrangian (CEL) approach. It was discovered that the CEL approach had accurately anticipated the mixing of materials in the stir zone (SZ) by comparing the SZ of the samples fabricated experimentally and modeled by simulation. Results show that the temperature and strain increase dramatically as the rotation speed increases from 500 to 900 rev min−1. The material flow obtained from the simulation shows that with increasing rotational speed or decreasing welding speed, AA7075 is more stretched towards AA5083 in the sheet’s higher surfaces, indicating an increase in material flow intensity. Better material mixing and increased material flow allowed for the achievement of the maximum tensile strength at the welding and rotation speeds of 36 mm min−1 and 900 rev min−1.
