Authors: Cui Jinrong , Mei Hao , Sun Haosen , Jingqi Ye , Hu Wei , Xu Yong 
Published: January 2023

AbstractCompared with the space on the ground, if there is a fire in the urban complex underground space, the loss will be greatly harmful. In addition, the complex underground space is usually connected with other large space areas and densely populated. Once a fire occurs in the complex underground space, it will cause huge property losses and casualties. In order to reduce the risk of fire, it is necessary to deeply understand the development rules and characteristics of fire in the complex underground space of the city. This article has mainly carried on the following work: (I) A particularly complex model of the multi‐storey subway station was built. On this basis, three groups of comparative experiments were conducted to study the effects of fire power, fire location and smoke control system on fire development, and the conclusion that fire location is the most important factor for fire development was obtained; (II) In order to explore the entire space fire and the local space fire, CFD (Computational Fluid Dynamics) is used to build a large‐size fire model and a small‐size fire model respectively; (III) Multiple detector data as temperature slices were built, and it is expected to make full use of the simulation data to deduce the important index of fire location in the early stage of fire. All of the works in this paper will provide reference experimental data for the prevention and firefighting of a sudden fire in the complex underground space.
Pattern synthesis of dual‐polarised conformal array based on adaptive iterative convex optimisation

Published: January 2023

AbstractThis study focuses on the shaped beam pattern synthesis based on the convex optimisation method for conformal arrays. First, the original pattern synthesis problem is transformed into a constrained optimisation problem for the power pattern. Then, it is rewritten as a convex optimisation problem through a linear approximation of weight vector. In order to enhance the resiliency of the algorithm, a robust linear approximate method is proposed with an adaptive upper bound of step size. The loss between the obtained and desired pattern is defined to dynamically adjust the upper bound. Benefiting from the flexible constraint, the proposed method can achieve the arbitrary beam pattern with fast convergence and robustness. Finally, numerous typical examples are provided to demonstrate the validity of the proposed method.

Published: January 2023

AbstractThe rapid development of Open‐Source Software (OSS) has resulted in a significant demand for code changes to maintain OSS. Symptoms of poor design and implementation choices in code changes often occur, thus heavily hindering code reviewers to verify correctness and soundness of code changes. Researchers have investigated how to learn meaningful code changes to assist developers in anticipating changes that code reviewers may suggest for the submitted code. However, there are two main limitations to be addressed, including the limitation of long‐range dependencies of the source code and the missing syntactic structural information of the source code. To solve these limitations, a novel method is proposed, named Graph Transformer for learning meaningful Code Transformations (GTCT), to provide developers with preliminary and quick feedback when developers submit code changes, which can improve the quality of code changes and improve the efficiency of code review. GTCT comprises two components: code graph embedding and code transformation learning. To address the missing syntactic structural information of the source code limitation, the code graph embedding component captures the types and patterns of code changes by encoding the source code into a code graph structure from the lexical and syntactic representations of the source code. Subsequently, the code transformation learning component uses the multi‐head attention mechanism and positional encoding mechanism to address the long‐range dependencies limitation. Extensive experiments are conducted to evaluate the performance of GTCT by both quantitative and qualitative analyses. For the quantitative analysis, GTCT relatively outperforms the baseline on six datasets by 210%, 342.86%, 135%, 29.41%, 109.09%, and 91.67% in terms of perfect prediction. Meanwhile, the qualitative analysis shows that each type of code change by GTCT outperforms that of the baseline method in terms of bug fixed, refactoring code and others' taxonomy of code changes.

Serial Subtraction Alters Lateral Step-down Tibiofemoral Kinematics
in Healthy Adults
Authors: Thomas Jacob , Weiss Samantha , Bliss Rebecca , Guess Trent 
Published: January 2023

AbstractThis study evaluated the effects of two types of cognitive dual-tasking on
three-dimensional knee kinematics during the lateral step-down. 19 healthy
individuals (22.05±1.61 yrs., 173.92±9.21 cm,
67.99±12.65 kg) participated in this study. Participants
completed 5 repetitions of a lateral step-down task for each leg and each
testing condition (control, Stroop, and serial subtraction by seven). An
electromagnetic motion sensor was attached to the femur via compression clamp
placed about the medial and lateral epicondyles. Another sensor was attached
2 cm below the ipsilateral tibial tuberosity. A custom MATLAB algorithm
located the knee joint axis of rotation from dynamic knee flexion and extension.
Discrete kinematics at peak flexion were used in this study. Paired samples
t-tests were used to compare average frontal, transverse, and sagittal plane
knee position at maximum flexion between conditions for each leg. No significant
differences were found for either limb between control and Stroop conditions.
Comparisons revealed significant differences in frontal and transverse plane
knee angles at peak flexion between the control and serial subtraction by seven
conditions. These findings indicate serial subtraction by seven requires
different cognitive processing abilities which may cause greater interference
with some aspects of motor control.
The Impact of Information About COVID-19 on the Endocrine Stress
System and Cognitive Distortions

Published: January 2023

AbstractThe coronavirus disease 2019 (COVID-19) pandemic is one of the major health
concerns worldwide affecting not only human physical health but also
contributing to the development of many mental disorders including
impairment of the cognitive function. It is highly conceivable that
elevation of the stress hormones, i.e., glucocorticoids and catecholamines,
due to the infection, as well as the presence of psychosocial stressors,
such as COVID-19 information, play a critical role in the development of
these disorders. In the present study, the potential impact of exposure to
COVID-19 information on the cognitive distortion and stress levels was
analyzed in a population of 32 first-year medical sciences students using
the stress assessment questionnaire (SAQ) and the posttraumatic cognitions
inventory (PTCI) surveys. Both surveys demonstrated no acute change in the
stress and post-traumatic cognition levels between medical sciences students
who were either exposed or not to information about COVID-19. Interestingly,
analysis of the stress and cognition points across the first and second
measurements of the SAQ categories revealed a significant change in the
control group but not in the experimental group. In addition, there was no
significant difference among groups when considering the time*group
factor. To conclude, we found that exposure to information about COVID-19
did not contribute acutely to cognitive distortion and stress levels among
participating students. The previous exposure to COVID-19-related
information from media and living during the COVID-19 pandemic era might
have enhanced the awareness of the students to the situation.
A Prescription for Internet: Feasibility of a Tablet Loaner Program to Address Digital Health Inequities
Authors: Brewster Ryan C.L. , Zhang Jessica , Stewart Melissa , Kaur Ravneet , Arellano Marlíse , Bourgeois Fabienne 
Published: January 2023

Abstract
Objective The coronavirus disease 2019 pandemic accelerated the adoption of telehealth technologies. Persistent disparities in telecommunication devices, internet connectivity, and digital literacy, however, undermine the potential for telemedicine to reduce barriers to health care access. Health systems may have a role in addressing these structural inequities. We describe the operationalization and feasibility of an internet-enabled tablet loaner program at a freestanding children's hospital.
Methods Between October 2020 and October 2021, pediatricians enrolled families through ambulatory clinics at an academic urban freestanding children's hospital. Eligibility criteria included difficulty accessing virtual care due to lack of stable internet or device. Tablets featured an unlimited data package, access to the patient portal, and virtual visit platform. A private technology company managed device configuration and distribution. To characterize program impact, we compared the proportion of completed clinical encounters during the intervention compared with a preintervention period (March 2020–October 2020) and conducted a qualitative survey with program participants. Participant and visit characteristics were obtained from the electronic medical record and summarized with descriptive statistics.
Results A total of 111 families participated in the tablet loaner program, the majority of whom were Hispanic (51.4%) and black, non-Hispanic (26.1%), and publicly insured (64.9%). Between the preintervention and intervention periods, there was a significant increase in completed video- and phone-based virtual visits (75.3 vs. 79.1%, p = 0.038). The proportion of video-based only visits increased from 82.9 to 88.9%. p < 0.001. Families reported that the tablet improved the patient's ability to receive medical care (93.7%) and was easy to use (93.9%).
Conclusion The tablet loaner initiative was associated with an improvement in markers of virtual visit engagement and health care experience. Efforts to expand telemedicine equity must consider technological access and digital literacy as well as broad coalitions across industry, government, and community organizations.
Enantioselective Formal Total Synthesis of Damsin
Authors: Nakada Masahisa , Sugiyama Ryoji 
Published: January 2023

AbstractEnantioselective formal total synthesis of damsin, which was isolated from Compositae Ambrosia maritima L., is described. The highly enantio- and diastereoselective catalytic Mukaiyama–Michael reaction and subsequent highly stereoselective epimerization shorten the synthetic steps. It is also reported that the enolate, which was formed by the reaction of β-keto sulfone with lithium naphthalenide, reacted with methyl cyanoformate to form a quaternary stereogenic center in high yield with high stereoselectivity. This finding extends the synthetic chemistry starting from β-keto sulfones.
Left Ventricular Diastolic Dysfunction in Patients with Subclinical Hypothyroidism: A Single South Indian Tertiary Care Centre Study
Authors: Kuchulakanti Anurag S. , Sharma Raghava , Utagi Basavaraj 
Published: January 2023

Abstract
Context Subclinical hypothyroidism (SCH) has been implicated in left ventricular diastolic dysfunction (LVDD).
Aims To study the association between SCH and LVDD.
Objectives To analyze the association between SCH and LVDD. To correlate the amount of LVDD with the serum thyroid-stimulating hormone (TSH) levels.
Settings and Design Single-center case–control study.
Methods and Material A case–control study was conducted between January 2020 and June 2021. A total of 36 cases of SCH were enrolled in the study and 36 age- and gender-matched euthyroid controls were included. Each individual's LV diastolic functioning was assessed by 2D echocardiography. LVDD was graded and compared between cases and controls.
Statistical Analysis Used The sample size was calculated to be 72 based on previous studies. Statistical analysis was performed using the IBM SPSS software version 20. A p-value of less than 0.05 was considered significant.
Results SCH was more commonly seen among females (75%) as compared with males (25%). Among cases, a majority of them (75%) had grade 1 SCH (i.e., TSH < 10 mU/L) and 25% of them had grade 2 SCH (i.e., TSH ≥ 10 mU/L). Among all the parameters assessed for LV diastolic function, the isovolumetric relaxation time and septal E/e' ratio was found to be significantly higher in cases than in controls and mitral E wave deceleration time (DT) significantly lower in cases. A statistically significant majority (72.2%) of the patients with SCH had some form of LVDD as compared with controls (30.5%)
Conclusions Walk-in outpatient department patients who opt for health check-up packages should be screened for SCH. SCH is statistically significantly associated with higher grades of LVDD as compared with age- and gender-matched euthyroid controls.
Locked Distal Ulna Volar Dislocation Associated with a Malunited Fracture of the Distal Radius
Authors: Krishna Sathya Vamsi , Fernandez Diego L. 
Published: January 2023

Abstract
Background The volar dislocation of the distal ulna is an uncommon injury and often missed due to its rarity. If diagnosed early, it can be managed with a simple closed reduction followed by immobilization. Open reduction is recommended in case of any interposition preventing reduction.
Case Description In this case report, we present a rare case of neglected volar distal ulna dislocation associated with a distal radius fracture presenting with a fixed supination deformity that was managed successfully with a Sauvé- Kapandji procedure using a modified approach to restore forearm rotation. At 10 months, the patient had a good union at the distal radio ulnar joint (DRUJ) with improved forearm rotations.
Literature Review To our knowledge no previous cases of neglected volar distal ulna dislocation with distal radius fracture has been reported in the literature.
Clinical Relevance If DRUJ stability cannot be restored after closed reduction of distal radius fracture, open reduction and internal fixation of the fracture should always be performed to avoid subsequent DRUJ subluxation/dislocations.

Abstract
Objective The aim of this study was to employ artificial intelligence (AI) via convolutional neural network (CNN) for the separation of oral lichen planus (OLP) and non-OLP in biopsy-proven clinical cases of OLP and non-OLP.
Materials and Methods Data comprised of clinical photographs of 609 OLP and 480 non-OLP which diagnosis has been confirmed histopathologically. Fifty-five photographs from the OLP and non-OLP groups were randomly selected for use as the test dataset, while the remaining were used as training and validation datasets. Data augmentation was performed on the training dataset to increase the number and variation of photographs. Performance metrics for the CNN model performance included accuracy, positive predictive value, negative predictive value, sensitivity, specificity, and F1-score. Gradient-weighted class activation mapping was also used to visualize the important regions associated with discriminative clinical features on which the model relies.
Results All the selected CNN models were able to diagnose OLP and non-OLP lesions using photographs. The performance of the Xception model was significantly higher than that of the other models in terms of overall accuracy and F1-score.
Conclusions Our demonstration shows that CNN models can achieve an accuracy of 82 to 88%. Xception model performed the best in terms of both accuracy and F1-score.
