Research on Surge Suppression of Timing Fuze Timing Starting Point Based on NMOSFET Device
Authors: Yang Chang Qing , Ma Shao Jie , Li Fei Yin , Tang Tong , Gui Di , Zhang Ying Zhong 
Published: March 2023

Abstract
When the timing fuze verification equipment simulates the timing fuze starting signal, the transient surge will interfere with the starting signal, resulting in inaccurate timing starting signal detection and time error. Through the Multisim process simulation of the timing starting point signal simulation module in the device, combined with the 'Miller platform' effect of the NMOSFET device, the value of the parallel capacitor CGD’ of the designed transient surge suppression circuit is studied. When CGD’ is 0.2uf, it can effectively suppress the surge, thus ensuring the accuracy of the timing starting point of the timing fuze.
A New Design of the 3D Deployable Space Antenna Structure
Authors: Du Yuwen 
Published: March 2023

Abstract
Communication and energy supply are critical in different sophisticated space missions in the aerospace industry. However, rockets have limited launch space and cannot carry such a massive support system. A space antenna deployable structure based on the scissor element and ring truss structure is proposed to overcome this challenge. This research studies the basic unit and its connection structure separately to investigate the mobility of the deployable structure. The connection structure and the basic units have one degree of freedom. Subsequently, a deployable ring truss system for satellite antennas is demonstrated. The kinematic models of the basic units and common deployment mechanisms have been constructed to demonstrate the mechanism deployment performance. The designed deployable structure can further increase the mechanism’s deployment area by splicing multiple basic ring deployable structures. This newly designed space antenna deployable structure has greater flexibility and can effectively increase the deployment area of the ring truss.
Study on the effect of magnetic needle grinding on the surface integrity and service performance of medical Mg-0.8Ca alloy
Authors: Lv Shenjin , Wei Wei , Qiao Yang 
Published: March 2023

Abstract
Medical magnesium alloys as biodegradable medical materials are regarded as the third generation of biomedical materials with good biocompatibility and degradability. Still, their application is greatly limited due to their excessive corrosion rate and low mechanical strength. This paper investigates the effect of surface integrity, wettability, and corrosion resistance of Mg-0.8Ca alloy milled surfaces and further magnetic needle magnetic grinding treated surfaces. The test results show that the surface roughness increases after grinding due to the change in surface morphology and work hardening. Still, microhardness, residual compressive stress, wettability, and corrosion resistance are all improved, and the surface is more conducive to cell adhesion and growth. Comparative tests have shown that magnetic pin grinding can effectively enhance magnesium alloy’s application strength and serviceability.

Published: March 2023

Abstract
Recycling waste materials, such as partial replacement of WCA for natural aggregates in hot-mix asphalt, could be an option for addressing problems such as environmental pollution and the increasing demand for natural resources. Due to continual development and renovation in the construction industry, the generation of concrete waste has become one of the major challenges. Consequently, the purpose of this study was to develop an asphalt mix design utilizing waste concrete aggregate (WCA) as a partial substitute for natural aggregates (NA). The ratios of WCA10:NA90 and WCA30:NA70 are utilised to design the asphalt mixtures. In this study, asphalt mixtures containing 10 and 30 percent WCA are referred as WCA10 and WCA30, respectively. The density-voids analysis enables the determination of the optimum asphalt content that satisfies the criteria of the Malaysian Public Works Department (PWD). Results indicates that the criteria and design parameters of both mix conforms to the PWD specifications. The optimum asphalt content determined for both WCA10 and WCA30 asphalt mix is 5.7 and 5.8 percent respectively. The moisture sensitivity test is then performed on both WCA10 and WCA30 asphalt mixtures to determine how susceptible these mixtures are to moisture-induced damage. The tensile strength ratio (TSR) for WCA10 and WCA30 asphalt mixtures is 83.6 and 97.4 percent, respectively, which is greater than the minimal requirement of 80%. This investigation revealed that the use of WCA in hot-mix asphalt satisfies the moisture susceptibility requirements.
Comparison of Solute and Multicomponent Geothermometry: a Study Case of Mount Rajabasa Geothermal Field
Authors: Kusumasari B A , Iqbal M , Herdianita N R 
Published: March 2023

Abstract
Geothermometry has always been a preferred method to estimate reservoir temperature in a relatively quick process at minimum cost. Among several types of geothermometry, solute geothermometry is the most common to be used due to its relatively uncomplicated calculation. However, it often involves high uncertainties thus the estimated temperature is occasionally rather inaccurate. This research aims at applying a new statistical approach to geothermometry to yield a more reliable reservoir temperature estimation. The new approach is called multicomponent geothermometry. This method uses the iGeoT code with a simple automatization for estimating unknown or poorly unknown constrained parameters. This method is applied to the Mount Rajabasa Geothermal Field in Lampung Province, Indonesia, and later validated against reservoir temperature from solute geothermometry. Results indicate both methods yield similar values close to 260°. Despite the similarity, multicomponent geothermometry is believed to offer better quality results since it takes into consideration of full chemical analysis and mineral saturation indices to obtain optimization. The application of multicomponent geothermometry jointly with solute geothermometry in the research area has proved to significantly increase accuracy and reliability in estimating reservoir temperature. The methods presented in this research may be advantageous for easy-to-handle analysis of other geothermal fields with standard geochemical data without the need for a sophisticated analysis yet earning more accurate results.
A General Condition of Structural Distinguisher
Authors: Yang Yang , Liu Wenhao , Zeng Guang 
Published: March 2023

Abstract
This paper proposes a general construction method for structural distinguishers, based on the recently proposed ‘multiple-of-n property’ of a subspace trail. The multiple-of-n property refers to the fact that by appropriate choices of difference for a number of input pairs, it is possible to make sure that the number of times that the difference of the resulting output pairs lie in a particular subspace is always a multiple of n. We weaken the condition for constructing the structural distinguisher from the exact subspace trail to the general subspace trail and this general condition is applied to the SPN cryptographic algorithm, allowing a six-round structural distinguisher to be obtained for the first time. In this way, the best six-round Midori-64 distinguisher is constructed, with its data complexity being identical to Midori’s five-round structural distinguisher. We also applied this new condition to the SKINNY algorithm, extending its structural distinguisher from five to six rounds.

Published: March 2023

Abstract

Background
The incidence of inflammatory bowel disease (IBD) is rising worldwide, though the differences in health care utilization among different races and ethnicities remains uncertain. We aimed to better define this through a systematic review and meta-analysis.

Methods
We explored the impact of race or ethnicity on the likelihood of needing an IBD-related surgery, hospitalization, and emergency department visit. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated with I2 values reporting heterogeneity. Differences in IBD phenotype and treatment between racial and ethnic groups of IBD were reported.

Results
Fifty-eight studies were included. Compared with White patients, Black patients were less likely to undergo a Crohn’s disease (CD; OR, 0.69; 95% CI, 0.50-0.95; I2 = 68.0%) or ulcerative colitis (OR, 0.58; 95% CI, 0.40-0.83; I2 = 85.0%) surgery, more likely to have an IBD-hospitalization (OR, 1.54; 95% CI, 1.06-2.24; I2 = 77.0%), and more likely to visit the emergency department (OR, 1.74; 95% CI, 1.32-2.30; I2 = 0%). There were no significant differences in disease behavior or biologic exposure between Black and White patients. Hispanic patients were less likely to undergo a CD surgery (OR, 0.57; 95% CI, 0.48-0.68; I2 = 0%) but more likely to be hospitalized (OR, 1.38; 95% CI, 1.01-1.88; I2 = 37.0%) compared with White patients. There were no differences in health care utilization between White and Asian or South Asian patients with IBD.

Conclusions
There remain significant differences in health care utilization among races and ethnicities in IBD. Future research is required to determine factors behind these differences to achieve equitable care for persons living with IBD.
Emphasis of Diversity, Equity, and Inclusion on US Adult Infectious Disease Fellowship Program Websites in the Era of Virtual Recruitment
Authors: Tischendorf Jessica S , Filipiak Rachel , Zelenski Amy , Osman Fauzia , Siraj Dawd 
Published: March 2023

Abstract
Women and underrepresented-in-medicine applicants value a climate for diversity when selecting graduate medical education training programs. Climate may not be accurately represented during virtual recruitment. Optimizing program websites may help overcome this barrier. We reviewed websites for adult infectious disease fellowships that participated in the 2022 National Resident Matching Program for emphasis on diversity, equity, and inclusion (DEI). Fewer than half expressed DEI language in their mission statement or had a dedicated DEI statement or webpage. Programs should consider emphasizing their commitment to DEI prominently on their websites, which may help recruit candidates from diverse backgrounds.

Published: March 2023

Abstract
The widespread adoption of virtual care technologies has quickly reshaped healthcare operations and delivery, particularly in the context of community medicine. In this paper, we use the virtual care landscape as a point of departure to envision the promises and challenges of artificial intelligence (AI) in healthcare. Our analysis is directed towards community care practitioners interested in learning more about how AI can change their practice along with the critical considerations required to integrate AI into their practice. We highlight examples of how AI can enable access to new sources of clinical data while augmenting clinical workflows and healthcare delivery. AI can help optimize how and when care is delivered by community practitioners while also improving practice efficiency, accessibility, and the overall quality of care. Unlike virtual care, however, AI is still missing many of the key enablers required to facilitate adoption into the community care landscape and there are challenges we must consider and resolve for AI to successfully improve healthcare delivery. We discuss several critical considerations, including data governance in the clinic setting, healthcare practitioner education, regulation of AI in healthcare, clinician reimbursement, and access to both technology and the internet.
Absence of SICKLE triggers programed cell death by disturbing alternative splicing and decay of mRNAs
Authors: Wu Chengyun , Zhen Weibo , Wang Xingsong , Li Yan , Wang Wei , Hu Zhubing 
Published: March 2023

AbstractProgramed cell death (PCD) plays fundamental roles in plant development and responses to environmental stresses. Here, we report a protein, SICKLE (SIC), which represses PCD. In Arabidopsis (Arabidopsis thaliana), the loss-of-function mutant of SIC, sic-4, hyperaccumulated lariat intronic RNAs (lariRNAs) and exhibited PCD. The gene encoding an RNA debranching enzyme 1 (DBR1), a rate-limiting enzyme for lariRNAs decay, was overexpressed to reduce the level of lariRNAs in the sic-4 mutant, which led to suppression of PCD. Meanwhile, another lariRNAs hyper-accumulating mutant, dbr1-2, also exhibited PCD, further indicating that sic-4 PCD is caused by hyper-accumulation of lariRNAs. Transcriptional profiling analyses revealed that the sic-4 mutation disturbed alternative splicing and decay of mRNAs associated with salicylic acid (SA) homeostasis, a well-known molecule functioning in PCD regulation. Moreover, SA is dramatically increased in sic-4 and the disruption of SA biosynthesis and signaling suppressed PCD in the mutant, demonstrating that SA functions downstream of sic-4. Taken together, our results demonstrate that SIC is involved in regulating SA-triggered PCD.
The 2020 derecho revealed limited overlap between maize genes associated with root lodging and root system architecture

Published: March 2023

AbstractRoots anchor plants in soil, and the failure of anchorage (i.e. root lodging) is a major cause of crop yield loss. Anchorage is often assumed to be driven by root system architecture (RSA). We made use of a natural experiment to measure the overlap between the genetic regulation of RSA and anchorage. After one of the most devastating derechos ever recorded in August 2020, we phenotyped root lodging in a maize (Zea mays) diversity panel consisting of 369 genotypes grown in 6 environments affected by the derecho. Genome-wide and transcriptome-wide association studies identified 118 candidate genes associated with root lodging. Thirty-four percent (40/118) of these were homologs of genes from Arabidopsis (Arabidopsis thaliana) that affect traits such as root morphology and lignin content, expected to affect root lodging. Finally, gene ontology enrichment analysis of the candidate genes and their predicted interaction partners at the transcriptional and translational levels revealed the complex regulatory networks of physiological and biochemical pathways underlying root lodging in maize. Limited overlap between genes associated with lodging resistance and RSA in this diversity panel suggests that anchorage depends in part on factors other than the gross characteristics of RSA.
RHO OF PLANT proteins are essential for pollen germination in Arabidopsis

Published: March 2023

Abstract
Pollen germination is a process of polarity establishment, through which a single and unique growth axis is established. Although most of the intracellular activities associated with pollen germination are controlled by RHO OF PLANTs (ROPs) and increased ROP activation accompanies pollen germination, a critical role of ROPs in this process has not yet been demonstrated. Here, by genomic editing of all 4 Arabidopsis (Arabidopsis thaliana) ROPs that are preferentially expressed in pollen, we showed that ROPs are essential for polarity establishment during pollen germination. We further identified and characterized 2 ROP effectors in pollen germination (REGs) through genome-wide interactor screening, boundary of ROP domain (BDR) members BDR8 and BDR9, whose functional loss also resulted in no pollen germination. BDR8 and BDR9 were distributed in the cytosol and the vegetative nucleus of mature pollen grains but redistributed to the plasma membrane (PM) of the germination site and to the apical PM of growing pollen tubes. We demonstrated that the PM redistribution of BDR8 and BDR9 during pollen germination relies on ROPs but not vice versa. Furthermore, enhanced expression of BDR8 partially restored germination of rop1 pollen but had no effects on that of the quadruple rop pollen, supporting their genetic epistasis. Results presented here demonstrate an ROP signaling route essential for pollen germination, which supports evolutionarily conserved roles of Rho GTPases in polarity establishment.
EVALUATION OF ACCURACY AND INTRINSIC UNCERTAINTY OF AUTOMATED IMAGE REGISTRATION FOR A 6D KV-CBCT IMAGE GUIDANCE SYSTEM: A CONCURRENT ANALYSIS WITH A MACHINE PERFORMANCE CHECK

Published: March 2023

Abstract
The accuracy and uncertainty of the automated image registration (AIR) algorithm in a six-dimensional (6D) kilovoltage cone-beam computed tomography (kV-CBCT) image-guided radiation therapy (IGRT) system were evaluated with a concurrent analysis of machine performance check (MPC). The MPC was performed before (MPCpre) and after (MPCpost) each accuracy and intrinsic uncertainty measurement. The accuracy was evaluated for 25 sets of the known shifts applied to the Catphan-504 phantom through a 6D robotic couch in the head, thorax, and pelvis CBCT acquisition modes. The uncertainty was evaluated for the intensity range, soft tissue, and bone matching filters in the head, thorax and pelvis CBCT acquisition modes. The mean ΔMPC (MPCpost–MPCpre) for all test parameters was within 0.02 ± 0.08 mm and 0.00 ± 0.02°. The overall average accuracy in AIR of 6D kV-CBCT IGRT in all translational and rotational axes was within 0.05 ± 0.76 mm and 0.02 ± 0.07°, respectively, for all CBCT modes. The overall mean population (Mpop), systematic (Σ) and random (σ) errors were within 0.47, 0.53 and 0.24 mm and within 0.03, 0.08 and 0.07° in translational and rotational axes, respectively, for all matching filters in all CBCT modes. The accuracy and intrinsic uncertainty in the AIR of the 6D kV-CBCT IGRT were within acceptable limits for clinical use.
Clitoral adhesions: a review of the literature
Authors: Romanello Jennifer P , Myers Monica C , Nico Elsa , Rubin Rachel S 
Published: March 2023

Abstract

Introduction
Clitoral adhesions occur when the prepuce adheres to the glans. These adhesions have been found in up to 22% of women seeking evaluation for sexual dysfunction. The etiology of clitoral adhesions remains largely unclear. Studies published to date on the presentation and management of clitoral adhesions are relatively recent and raise questions for future research.

Objectives
We sought to provide a background of existing knowledge on the prevalence, presentation, etiology, associated conditions, and management of clitoral adhesions and to identify areas for future research.

Methods
A review of literature was performed for studies that investigate clitoral adhesions.

Results
Conditions associated with chronic clitoral scarring appear to have a role in the development of clitoral adhesions. Symptoms include clitoral pain (clitorodynia), discomfort, hypersensitivity, hyposensitivity, difficulty with arousal, and muted or absent orgasm. Complications include inflammation, infection, and the development of keratin pearls and smegmatic pseudocysts. There are surgical and nonsurgical interventions to manage clitoral adhesions. Additionally, topical agents can be included in conservative and/or postprocedural management. Although many studies on clitoral adhesions are limited to patients with lichen sclerosus (LS), clitoral adhesions are not confined to this population.

Conclusion
Areas for future research include etiologies of clitoral adhesion; such knowledge is imperative to improve prevention and management. Also, in previous studies, patients were instructed to apply various topical agents and manually retract the prepuce for conservative management or postlysis care. However, the efficacy of these interventions has not been investigated. Surgical and nonsurgical lysis procedures have been described for the management of pain and difficulties with arousal and orgasm that are causes of the sexual dysfunction associated with clitoral adhesion. Although previous studies have assessed efficacy and patient satisfaction, many of these studies were limited to small sample sizes and focused solely on patients with LS. Future studies are needed to inform a standard of care for the management of clitoral adhesions.
