General Veterinary - Abstract
As an important organ that coordinates the neuroendocrine system, the hypothalamus synthesizes and secretes reproductive hormones that act on the goat organism, thereby precisely regulating follicular development and reproductive processes in goats. However, it is still elusive to explore the mechanism of hypothalamic effects on goat fertility alone. Therefore, RNA-seq was used to analyze the gene expression in hypothalamic tissues of goats in high fertility group (HFG: litter size per litter ≥2) and low fertility group (LFG: litter size per litter = 1), and identified the differential lncRNAs and mRNAs and their associated pathways related to their fertility. The results showed that a total of 23 lncRNAs and 57 mRNAs were differentially expressed in the hypothalamic tissue of high and low fertility goats. GO terms and KEGG functional annotation suggest that DE lncRNAs and DE mRNAs were significantly enriched in hormone-related pathways regulating ovarian development, hormone synthesis and secretion, regulation of reproductive processes, Estrogen signaling pathway, Oxytocin signaling pathway and GnRH signaling pathway. And we constructed a co-expression network of lncRNAs and target genes, and identified reproduction-related genes such as NMUR2, FEZF1, and WT1. The sequencing results of the hypothalamic transcriptome have broadened our understanding of lncRNA and mRNA in goat hypothalamic tissue and provided some new insights into the molecular mechanisms of follicle development and regulation of its fertility in goats.

Clinical Practice - Abstract
Gastric cancer is one of the most common malignancies of the digestive system, and the number of deaths continues to increase. The standardized management of the diagnosis and treatment of gastric cancer is challenging due to the great differences in the diagnosis and treatment of gastric cancer in different regions. The Gastric Cancer Expert Committee of the National Cancer Quality Control Center (NCQCC) identified a lack of authoritative quality control standards as an opportunity to utilize its multidisciplinary membership to improve the standardized diagnosis and treatment of gastric cancer. The Gastric Cancer Expert Committee of the NCQCC aims to promote quality control and national standardization, uniformity, and normalization of gastric cancer diagnosis and treatment, which ultimately improved the survival rate and quality of life of gastric cancer patients. A panel of experts with gastrointestinal cancer surgery, gastrointestinal cancer medicine, medical imaging, pathology and radiotherapy were drawn together and determined the quality control standards for the standardized diagnosis and treatment of gastric cancer. The authors then utilized a modified Delphi approach to generate consensus recommendations.

Recently, abundant transport phenomena characterizing the surface states of Weyl semimetals (WSMs) have been reported. To generate these phenomena, electrons have to complete a closed intersurface orbit. Due to the unavoidable impurities in real materials, this orbit would be destroyed by the impurity scattering, which limits the detection of the surface states in WSMs. Here, we investigate the RKKY interaction between magnetic impurities, solely mediated by a single surface band, in semi-infinite WSMs. It is found that peculiar oscillations and slowly decaying laws of the RKKY interaction can act as the signals to capture the dispersive nature of the surface states of WSMs. The underlying physics is attributed to two effects: the band-edge effect and the bending effect of the surface band, which can control the RKKY interaction individually or compete with each other to produce more complex magnetic behaviors. In addition, the band-edge effect together with the finite Fermi energy would result in another interesting oscillation with battering pattern. All the results are significantly different from that in previous literatures where surface states have to couple with bulk states (or other surface states of different spins) to generate nonzero magnetic interaction. Compared to the previous models of surface states, the model here is more practical and is helpful for the deeper understanding of the surface magnetic properties in WSMs., 12 pages, 9 figures

Seismic data plays a vital role in oil and gas exploration and geological exploration.Accurate and detailed seismic data can help to provide accurate guidance for oil and gas exploration,reduce the risk of exploration,and generate huge social and economic benefits.In terms of improving the resolution of seismic data,the existing methods are difficult to recover detailed geolo-gical information when facing large amounts of data,and have poor results in high-resolution recovery,denoising performance and efficiency,and it is difficult to meet the actual needs.Seismic data can reflect the composition of geological structures and strata,and have the characteristics of high local correlation and low global correlation.At the same time,the high frequency part of seismic data usually contain important geological exploration information such as layering,chasm,etc.In view of the characteristics of seismic data,this paper innovatively transforms the problem of seismic data reconstruction into the problem of image super-resolution,and proposes a method for super-resolution of seismic data based on the generative adversarial networks.In view of the characteristics of high local correlation and low global correlation of seismic data distribution,a residual attention module is designed to mine the inherent correlation of seismic data,so as to recover more refined seismic data.By training a generative adversarial network model with a relative generative adversarial loss function,the generative network is used to perform super-resolution recovery of the seismic data to recover more refined seismic data.In this paper,experimental verification is carried out on real seismic data,and the experimental results show that the proposed method has a good effect on super-resolution of seismic data and has strong practicability.

In this study, silage Pennisetum sinese Roxb-based diet was replaced with fermented pineapple residue (FPR) at the replacement ratio of 0% (CON), 25% (T25), and 50% (T50) in fattening Simmental bulls for 30 days to evaluate the effects of FPR on growth performance, serum indexes, and ruminal characteristics. A total of 30 Simmental bulls (546 ± 44 kg initial BW) were allocated to three groups according to a completely randomized design. On day 30, the slaughter performance and meat quality were determined. Rumen fluids were collected for analyzing the rumen fermentation parameters and microbiota composition on day 30. The results showed that the average daily weight gain increased (P < 0.05) as the proportion of FPR rose. Within treatments, the T25 group reached more profit (5.34 RMB per day per bull) than CON while T50 was 3.69. The content of crude fat, cysteine, and proline in the muscle of T50 increased significantly (P < 0.05). The amounts of tyrosine, proline, and phenylalanine were significantly increased in the T25 (P < 0.05). The beta diversity analysis showed significant differences among the rumen bacterial flora of each group (P < 0.05). In the T25 group, the relative abundance of Spirochaetes decreased significantly (P < 0.05). The relative abundance of Lachnospiraceae_bacterium_RM44 was significantly lower (P < 0.05). Thus, FPR could improve the growth performance, economic benefits, and meat quality without adverse effects on ruminal characteristics.

Nano-SiO2 particles have been incorporated into high-performance poly(ether ketone ketone) (PEKK) polymers to prepare satisfactory nanocomposite substrates for fifth-generation (5G) communication. Significantly lower dielectric constant (er), dielectric loss (tan δ), and linear coefficient of thermal expansion (CTE) were found for each PEKKaxSiO2y nanocomposite film series incorporated with proper loadings of nano-SiO2 particles. The dielectric characteristics measured for each PEKKaxSiO2y nanocomposite film series decreased to a minimum as the nano-SiO2 loading approached an optimum value. Satisfactory er (2.74 at 1 MHz), tan δ (0.00309 at 1 MHz), and linear CTE (~ 37 × 10−6/°C) for 5G high-speed communication were found for the nanocomposite film modified with the optimum nano-SiO2 loading of 10 wt.%. The porosity values measured for each PEKKaxSiO2y film series remained nearly zero then increased abruptly as the nano-SiO2 loading exceeded 10 wt.%. The free volume characteristics evaluated for each PEKKaxSiO2y film series increased to a maximum as the nano-SiO2 loading reached the optimum value of 10 wt.%. Possible explanations for the noticeably reduced dielectric and linear CTE characteristics found for PEKKaxSiO2y composite films are proposed.

Aqueous supercapacitor shows a narrow operating voltage range because of the limitation of the water electrolysis, resulting in low energy density. In this work, a nanoporous MnO2 entangled hierarchical porous carbon skeleton (simplified to MHPC) has been successfully prepared. Aqueous asymmetric supercapacitor has been assembled by employing the MHPC as a positive electrode, a hierarchical porous carbon skeleton (HPC) as a negative electrode, and a neutral Na2SO4 aqueous solution as electrolyte. The assembled asymmetric supercapacitor can be stably charged in an aqueous medium in a wide voltage range of 0–2.5 V and delivers a maximum energy density of 20.8Wh/kg at a power density of 0.25 kW/kg and 25 kW/kg at an energy density of 11.1 Wh/kg in a 1 M Na2SO4 aqueous solution. This strategy provides a new idea for developing high-energy supercapacitor.

We demonstrated a simple and environment-friendly method in the preparation of N-doped carbon/PANI (NCP) composite without binder. The structure and the property of NCP have been characterized by XPS, IR, XRD, SEM, CV, GCD and EIS. The results reveal that NCP has high capacitance performance of up to 615 F·g−1 at 0.6 A·g−1. Additionally, the asymmetric NCP300//carbon supercapacitor delivers a high capacitance (111 F·g−1 at 1 A·g−1) and a capacity retention rate of 82% after 1200 cycles at 2 A·g−1. The ASC cell could deliver a high energy density of 39.1 W·h·kg−1 at a power density of 792.6 W·kg−1.

To investigate the significance of peripheral blood lymphocyte to monocyte ratio (LMR) and corrected levels of serum calcium (cCa) as prognostic markers for the newly diagnosed multiple myeloma (MM) patients.The clinical data of 114 newly diagnosed MM patients in the Second Affiliated Hospital of Kunming Medical University from January 2013 to March 2020 were retrospectively analyzed. Receiver operating characteristic (ROC) curve analysis was used to identify the optimal cutoff value, and the patients were divided into high LMR group and low LMR group (LMR≥3.35 and LMR3.35). Moreover, the patients were divided into four groups according to initial diagnosis LMR and LMR after four courses of treatment (LMR4): Group A (LMR≥3.35, LMR4≥3.35), Group B (LMR≥3.35, LMR43.35), Group C (LMR3.35, LMR4≥3.35), and group D (LMR3.35, LMR43.35). The simple prognosis model was established by combined with LMR and cCa, the patients were divided into Group a (no risk factor), group b (1 risk factor) and Group c (2 risk factors). Independent sample T-test, Pearson Chi-square test or Mann-Whitney U test were used to evaluate the differences between various parameters, and Kaplan-Meier method and Cox regression were used for survival analysis.The median follow-up time was 13.05(0.1-72.5)months. Survival analysis showed that the patients with low LMR predicted poor prognosis, the overall survival (OS) time of the patients with low LMR was significantly shorter (17 vs 50.5 months, P=0.006) than the patients with high LMR, the difference was also significant between group A and Group D (56.5 vs 30.5 months, P=0.043). The OS of the patients was also significantly shorter in the high cCa group (≥2.75 mmol/L) compared with normal group (8.5 vs 34 months, P=0.006). Multivariate survival analysis showed that LMR3.35 (P=0.028) and cCa≥2.75 mmol/L (P=0.036) were the independent risk factors affecting prognosis of MM patients. The comparison of risk factors showed that the median OS of Group a, b and c was 50, 20, and 8.5 months, respectively. The prognosis of the patients without risk factors was better than that of patients with 1-2 risk factors (Group a vs Group b, P0.0001; Group a vs Group c, P=0.002).LMR and cCa are the independent risk factors affecting the prognosis of newly diagnosed MM patients, and the development of a simple prognosis system combining them can quickly identify the prognosis of newly diagnosed MM patients.淋巴细胞/单核细胞比率与校正血钙作为新诊断多发性骨髓瘤预后标志物的意义.探讨外周血淋巴细胞与单核细胞比率(LMR)和校正后血清钙(cCa)作为新诊断多发性骨髓瘤(MM)患者预后标志物的意义.回顾性分析2013年1月至2020年3月昆明医科大学第二附属医院114例初诊MM患者的临床资料,采用ROC曲线确定变量的最佳临界值,将患者划分为高LMR和低LMR(LMR≥3.35和LMR3.35)两组,根据初诊及4个疗程治疗的LMR(LMR4)将患者分为A(LMR≥3.35,LMR4≥3.35)、B(LMR≥3.35,LMR43.35)、C(LMR3.35,LMR4≥3.35)和D(LMR3.35,LMR43.35)这4组。结合LMR和cCa制定简易预后模型,将患者划分为a(无危险因素)、b(1个危险因素)和c(2个危险因素)这3组。采用独立样本t检验和Pearson卡方检验或Mann-Whitney U检验评估各种参数的差异性,Kaplan-Meier法及Cox回归进行生存分析.中位随访时间13.05(0.1-72.5)个月。生存分析显示,初诊时较低的LMR能够预示更差的结局,其中低LMR组与高LMR组比较,总体生存时间(OS)明显缩短(17 vs 50.5个月,P=0.006)。同样可以观察到A与D组之间OS的差异(56.5 vs 30.5个月,P=0.043),高cCa(≥2.75 mmol/L)组与正常组比较,OS也明显缩短(8.5 vs 34个月,P=0.006)。多因素生存分析显示,LMR3.35(P=0.028)和cCa≥2.75 mmol/L(P=0.036)是MM患者的独立预后因素,危险因素分组比较显示,a、b及c组中位OS分别为50、20和8.5个月,无危险因素者预后均优于合并1-2个危险因素者(a vs b组,P0.0001;a vs c组,P=0.002).对于初诊MM患者,LMR和cCa是影响预后的独立风险因素,结合两者制定简易预后系统能够快速判断初诊MM患者的预后.

Patients suffering from cardiovascular disease lack suitable stent. In this study, a new polymeric composite material was prepared by incorporating various concentrations of gamma-glycidoxypropyltrimethoxysilane (GPTMS) into silk fibroin (SF), aiming at achieving a novel composite film with superior mechanical and biological properties, in order to match the requirement of cardiovascular tissue engineering stents. Fourier transform infrared spectroscopy (FTIR) analysis showed that GPTM could promote SF to transform from the original alpha helix and random coil/extension chain conformation to the beta-folded conformation. Tensile experiment indicated tensile strength and breaking elongation of SF/GPTMS hybrid film reach the maximum with 20% GPTMS content. Within a certain range, the water drop contact angle of SF/GPTMS hybrid film is positively correlated with the content of GPTMS. Endothelial cells (ECs) are best grown on hybrid SF/GPTMS hybrid film with 20% GPTMS content.

A dehydrative cross-coupling of 2H-chromene hemiacetals with ketones is described. Without the derivatization of 2H-chromene hemiacetals to 2H-chromene acetals, the direct C–OH/C–H coupling reaction has been accomplished with water as the only by-product. With the use of Sn(OTf)2 as the promoter, the reaction goes smoothly under mild conditions.

The aim of this trial was to assess whether the supplementation of vitamin E (VE) in high-concentrate diets could improve the fermentation and blood metabolism in the rumen of dairy cows, thereby modulating the degree of the subacute ruminal acidosis (SARA) response and improving the performance. Seven Holstein cows (four fitted with ruminal cannulas) were fed three diets (total mixed rations) during three successive periods (each lasted for 18 d): (1) the control diet (CON); (2) a high-grain (HG) diet, which was the control diet supplied with a 15% finely ground wheat diet (FGW); and (3) a high-VE diet (HGE), which was the control diet provided with a 15% FGW and 12,000 IU of VE/head per day. The results indicated that VE was able to alleviate the reduction in the dry matter intake (DMI) and milk fat yield in cows caused by HG diets. The supplementation of VE significantly reduced the levels of lipopolysaccharide (LPS), histamine (HIS), and the total volatile fatty acid (TVFA) in the rumen. The supplementation of VE observably increased the antioxidant capacity of the milk and plasma. In addition, VE markedly reduced the plasma levels of endotoxin, HIS, and pro-inflammatory factors. The supplementation of VE significantly enriched the differential metabolites of the purine metabolism, cysteine, methionine metabolism, and ABC transporter synthesis pathway in the serum. The supplementation of VE also significantly increased the relative abundance of Succiniclasticum and decreased the relative abundance of Treponema, thus reducing the production of TVFA in the rumen. In conclusion, considering that the cows in this trial had high ketone levels (BHBA > 2.3 mmol/L), we found that VE could improve the rumen fermentation and blood metabolism by modulating the relative abundance of rumen microorganisms, thereby mitigating a range of adverse effects caused by SARA.

In the three closed-loop servo system, the position loop is the key consideration object, and the transfer function directly reflects the relationship between the position instruction signal and the feedback signal. Because the servo system contains controller, motor, mechanism, control algorithm, and so on, the whole system is more complex, and all kinds of coefficient constant cannot be obtained accurately, so it is difficult to obtained transfer function accurately by modeling and simulation method. In order to improve the identification accuracy of the system transfer function, the amplitude-frequency and phase-frequency data are obtained by experimental method, and the algorithm program is written by MATLAB. The algorithm can identify the system transfer function quickly and accurately, and can achieve the identification accuracy that the absolute error of amplitude-frequency characteristic and phase-frequency characteristic is very small. It has great practical value for the research of servo control system.

We experimentally demonstrate a novel optical fiber chemosensor for trace Cu2+ ions detection that is implemented by using an in-line optical fiber Mach–Zehnder interferometer (MZI) in conjunction with an optoelectronic oscillator (OEO). The MZI is fabricated by lateral offset splicing a section of D-shaped fiber between two single-mode fibers. It splices the broadband optical source into a sinusoidal-shaped light, which can form a single passband microwave photonic filter (MPF) by combining the Mach–Zehnder modulator, a segment of fiber and a photodetector. The center frequency of the MPF, determined by the free spectra range of MZI, is affected by the solution concentration. Incorporating the MPF in the OEO sensor, the oscillation frequency is determined by the solution concentration. Therefore, we can estimate the solution concentration by measuring the microwave frequency change. We carry out a proof to concept experiment. High sensitivity Cu2+ ions concentration sensing with sensitivity of 13 Hz/(μM/L) is achieved. The maximum measurement error of concentration obtained is within 1.38 μM/L. The proposed sensor has merits of high interrogation speed, simple operation, high sensitivity and accuracy, offering the potentials in a wide range of biological application scenarios.

Article - Abstract
This chapter describes the clinical symptoms and signs of AECHB and HBV ACLF, classification, grading of HBV ACLF and their features, diagnostic principles and standards in liver pathology, biochemistry, and virology of HBV ACLF.Liver failure is defined as serious damage to the liver cause by a variety of etiologies, leading to liver function disorder or even decompensation, and clinical syndromes with coagulopathy, jaundice, hepatic encephalopathy, and ascites.Severe hepatitis B can be indicated pathologically by apparent hepatocellular necrosis, including extensive multifocal, confluent, bridging, sub-massive or massive necrosis.Laboratory tests during the course of severe exacerbation of chronic hepatitis B can reflect pathological changes and liver function in a timely manner, providing objective and informative reference data for evaluation of disease severity and treatment efficacy. Among the most important laboratory tests are those for prothrombin activity, international normalized ratio, and increases in total bilirubin concentration.Severe hepatitis B is associated with interactions between the virus and host factors. Detection of HBV DNA, HBV genotype, quasispecies and HBV mutation can provide important theoretical bases for the prevention, control or mitigation of the progress of severe hepatitis B.Noninvasive imaging modalities can be used to visualize the entire liver and parts of it. Measuring liver volume to evaluate liver size and liver reserve capacity is regarded as important in diagnosis, surgical approach and prognostic evaluation of patients with severe exacerbation of chronic hepatitis B and liver failure.Model for End-Stage Liver Disease (MELD) is the first quantitative method developed to assess whether a patient with liver failure requires a liver transplant. The predictive value of the MELD model has been improved by the MELD-Na, iMELD, and MESO models. Several other valuable prognostic models have been developed. For example, for patients with HBV-ACLF, the established TPPM scoring system was found to be more predictive than MELD score.

A highly efficient and regioselective self-coupling of C8-methylol catechin derivatives is developed for the synthesis of dimeric flavanol analogues under metal-free and mild conditions. Its applicability is showcased by the efficient synthesis of bisflavanol-type natural products bis-8,8′-catechinylmethane, bis-8,8′-epicatechinylmethane, talienbisflavan A, and oolonghomobisflavan A. The novel self-coupling mechanism sheds new light on the classical Friedel–Crafts alkylation mechanism in acid-catalyzed catechin–formaldehyde condensation.

Visual interfaces and wireless monitoring have played significant roles in the application of electromagnetic transmitters. Therefore, we have designed a wireless monitoring system that is based on the Visual Studio 2015 Windows form application by using C# language and multi-threading technology. The system can effectively implement many functions, including time monitoring via a real-time clock, switching of the transmitting frequency, changing of transmission mode, and the storage and verification of the transmitter condition information. These things allow the wireless monitoring system to support condition monitoring and operation control of the transmitter. The results of several field tests confirm that the proposed wireless monitoring system provides a user-friendly interface and convenient and stable operation. The system is able to satisfy the wireless monitoring and multifunctional demands for transmitters implemented in land electromagnetic exploration and act as a reference for scientific researchers pursuing instrument development and electromagnetic prospecting.

Codebooks with small maximum cross-correlation amplitudes are used to distinguish the signals from different users in CDMA communication systems. In this paper, we first study the Jacobi sums over Galois rings of arbitrary characteristics and completely determine their absolute values, which extends the work in [34], where the Jacobi sums over Galois rings with characteristics of a square of a prime number were discussed. Then, the deterministic construction of codebooks based on the Jacobi sums over Galois rings of arbitrary characteristics is presented, which produces asymptotically optimal codebooks with respect to the Welch bound. In addition, the parameters of the codebooks provided in this paper are new., Comment: arXiv admin note: substantial text overlap with arXiv:2001.04028

Codebooks with small maximum cross-correlation amplitudes are used to distinguish the signals from different users in code division multiple access communication systems. In this paper, several classes of codebooks are introduced, whose maximum cross-correlation amplitudes asymptotically achieve the corresponding Welch bound and Levenshtein bound. Specially, a class of optimal codebooks with respect to the Levenshtein bound is obtained. These classes of codebooks are constructed by selecting certain rows deterministically from circulant matrices, Fourier matrices and Hadamard matrices, respectively. The construction methods and parameters of some codebooks provided in this paper are new.

Fe(III)-oxyhydroxide composites are efficient adsorption materials, however, their detailed geometrical structures and adsorption mechanisms in a broad pH range are still unclear. In this study, the structures of arsenic(V) adsorbed on Fe(III)-oxyhydroxide adsorption complexes were investigated using hybrid density functional theory calculations together with experimental Fourier transform infrared (FT–IR) spectroscopy. Adsorption experiments showed higher arsenic(V) removal rates in the range of pH 5.0–10.0. FT–IR and X-ray diffraction (XRD) revealed that arsenic(V) is stably adsorbed by Fe(III)-oxyhydroxide complexes. The formation of monomeric As(V) appears to be favored in the 1.0–4.0 pH range, while dimeric and trimeric As(V)-Fe(III) oxyhydroxide complexes are preferably formed at higher pH (4.0–10.0). Namely, dimeric and trimeric Fe(III)-oxyhydroxides exhibited good removal efficiencies for arsenic(V) over a wide pH range. Interestingly, the stabilities of the complexes formed between As(V) and monomeric, dimeric and trimeric Fe(III)-oxyhydroxides follow the orders: As(V) trimer > As(V) dimer > As(V) monomer; these complexes are also interconvertible.

Monolayer WTe2 is predicted to be a quantum spin Hall insulator (QSHI) and electron transport along its edges has been experimentally observed. However, the 'smoking gun' of QSHI, spin momentum locking of the edge electrons, has not been experimentally demonstrated. We propose a model to establish the relationship between the anisotropic magnetoresistance (AMR) and spin orientation of the helical electrons in WTe2. Based on the predictions of the model, angular dependent magnetoresistance measurements were carried out. The experimental results fully supported the model and the spin orientation of the helical edge electrons was determined. Our results not only demonstrate that WTe2 is indeed a QSHI, but also suggest a convenient method to determine the spin orientation of other QSHIs., 32 pages, 11 figures

Objective: We aimed to evaluate the quantitative parameters of CT scans performed on pregnant women with COVID-19 who had different reverse transcription-polymerase chain reaction (RT-PCR) results.Methods: Pregnant women with suspected cases of COVID-19 pneumonia (confirmed by next-generation sequencing or RT-PCR) who underwent high-resolution lung CT scans were retrospectively enrolled. Patients were grouped based on the results of the RT-PCR and the first CT scan: group 1 (double positive patients; positive RT-PCR and CT scan) and group 2 (negative RT-PCR and positive CT scan). The imaging features and their distributions were extracted and compared between the two groups.Results: Seventy-eight patients were admitted to the hospital between Dec 20, 2019, and Feb 29, 2020. The mean age of the patients was 31.82 years (SD 4.1, ranged from 21 to 46 years). The cohort included 14 (17.95%) patients with a positive RT-PCR test and 64 (82.05%) with a negative RT-PCR test, there were 37 (47.44%) patients with a positive CT scan, and 41 (52.56%) patients with a negative CT scan. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CT-based diagnosis of COVID-19 were 85.71%, 60.94%, 32.40%, 95.12% and 65.38%, respectively. COVID-19 pneumonia mainly involved the right lower lobe of the lung. There were 53 semi-quantitative and 59 quantitative parameters, which were compared between the two groups. There were no significant differences in the quantitative parameters. However, the Hellinger distance was significantly different between the two groups, albeit with a limited diagnostic value (AUC=0.63).Conclusions: Pregnant women with pneumonia usually present with typical abnormal signs on CT. Although multidimensional CT quantitative parameters are somewhat different between groups of patients with different RT-PCR results, it is still impossible to accurately predict whether the RT-PCR will be positive, which would allow for the earlier detection of SARS-CoV-2 infection.

Increased meningitis caused by extensively drug-resistant bacillary presents a significant challenge in antibiotic selection. The aim of our study was to evaluate the efficacy and safety of polymyxin in the treatment of post-neurosurgical meningitis due to the extensively drug-resistant bacillary in children.We performed a retrospective study on post-neurosurgical meningitis caused by the extensively drug-resistant bacillary in children, who were treated with polymyxin for ≥ 3 days.Among five post-neurosurgical meningitis cases that were included, the children were infected by Acinetobacter baumannii (n = 3), Klebsiella pneumonia (n = 1), and Pseudomonas aeruginosa (n = 1). The drug susceptibility test showed that they were extensively drug-resistant bacillary. Two patients received intravenous polymyxin E. Three children received intravenous combined with intraventricular injection of polymyxin B. One patient infected by Klebsiella pneumonia eventually died of septic shock. No serious adverse effects of polymyxin were observed.Polymyxin is a safe and effective therapy for post-neurosurgical, multidrug-resistant bacillary meningitis in children.

In order to meet the requirements of the angular position accuracy of the high-precision brushless servo assembly, it is necessary to analyze the factors affecting the position accuracy of the turntable. The study found that the axial pulsation, radial displacement and angular slew of the shafting system are the key factors affecting the accuracy of the mechanism. The paper analyzes the rotary error caused by these factors. Through the analysis of the positioning accuracy of the shafting system, this paper uses the error compensation method to correct the accuracy of the angular position. The result satisfies the requirement of the design index and shows the rationality of the design method.

The Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction has been extensively explored in isotropic Dirac systems with linear dispersion, which typically follows an exponent decaying rate with the impurity distance $R$, i.e., $J\propto 1/R^d$ ($1/R^{2d-1}$) in $d$-dimensional systems at finite (zero) Fermi energy. This fast decay makes it rather difficult to be detected and limits its application in spintronics. Here, we theoretically investigate the influence of anisotropic dispersion on the RKKY interaction, and find that the introduction of non-relativistic dispersion in semi-Dirac semimetals (S-DSMs) can significantly prolong the decay of the RKKY interaction and can remarkably enhance the Dzyaloshinskii-Moriya interaction around the relativistic direction. The underlying physics is attributed to the highly increased density of states in the linear-momentum direction as a result of the interplay of relativistic and non-relativistic electrons. Furthermore, we propose a general formula to determine the decaying rate of the RKKY interaction, extending the typical formula for isotropic DSMs. Our results suggest that the S-DSM materials are a powerful platform to detect and control the magnetic exchange interaction, superior to extensively adopted isotropic Dirac systems., Comment: 6 pages, 3 figures

As the condensed matter analog of Majorana fermion, Majorana zero-mode is well known as a building block of fault-tolerant topological quantum computing. In this review, we focus on the recent progress of Majorana experiments, especially experiments about semiconductor-superconductor hybrid devices. We first sketch Majorana zero-mode formation from a bottom-up view, which is more suitable for beginners and experimentalist. Then, we survey the status of zero-energy state signatures reported recently, from zero-energy conductance peaks, the oscillations, the quantization, and the interactions with extra-degrees of freedom. This paper also gives prospects on future experiments for advancing one-dimensional semiconductor nanowire-superconductor hybrid materials and devices., Comment: 14 pages, 8 figures
