Integrated energy‐efficient optimization for urban rail transit timetable
Authors: Deng Lianbo , Chen Ming , Duan Keyi , Li Ouyang , Shi Fengshou 
Published: May 2023

AbstractThe energy‐efficient optimization of the train timetable should be carried out on the basis of meeting passenger demand and determining the train operation plan. This paper proposes an integrated energy‐efficient optimization framework for the train timetable. Firstly, two energy‐efficient optimization strategies for this problem are proposed: inter‐station running time allocation and regenerative braking energy utilization. The first strategy aims to reduce the traction energy consumption, realized by selecting the profile based on a given set of speed profiles for each inter‐station sector when ensuring a stable travel time of train routing. The second strategy is intended to fully utilize the regenerative energy feedback from braking trains, realized by setting the departure time of trains based on a small‐range headway adjustment. Then, an integrated energy‐efficient optimization model of the timetable is developed and solved using the genetic algorithm. Finally, a case study of the Guangzhou Metro Line 8 is presented to verify the effectiveness of the method. The results show that the utilization rate of regenerative braking energy in the optimized timetable increases by 8.60%, and the total energy consumption decreases by 9.52%. Regenerative energy utilized roughly doubles during peak hours and increases more than twice as much during off‐peak hours.
Improved radar range and velocity resolution using the fast orthogonal search
Authors: Lloyd John , Korenberg Michael 
Published: May 2023

AbstractThe authors show improved radar range and velocity resolution is achieved using fast orthogonal search in place of the standard fast Fourier transform. The method reliably detects targets that are close either in range or in velocity, which is relevant today given recent advances in target swarms. The method presented also allows radars to detect slower targets closer to the zero‐Doppler region, like uncrewed aerial systems (drones) moving slowly to escape detection. The authors also show a novel method for estimating the velocity spectrum of a pulse‐Doppler radar using the in‐phase and quadrature samples directly by presenting unique terms to the fast orthogonal search. This eliminates the need to convert into complex samples for processing. The authors compared the performance of the new fast orthogonal search method against the fast Fourier transform using both simulated pulse‐Doppler radar data and real frequency‐modulated continuous wave radar data taken in an anechoic chamber. The simulated pulse‐Doppler scenarios included targets closely spaced in velocity and targets near the zero‐Doppler null, all at a variety of signal‐to‐interference ratios. In all cases, the fast orthogonal search method was shown capable of detecting both the closely‐spaced and near‐zero‐Doppler targets a greater percentage of time compared to the fast Fourier transform. Furthermore, when the methods were compared using real frequency‐modulated continuous wave radar data, the stationary targets were resolved at 0.4 m using the fast orthogonal search as compared to 0.6 m for the fast Fourier transform. Thus, this new method is capable of greater radar range and velocity resolution than the fast Fourier transform.

Transition-Metal-Free Cross-Coupling of Acetals and Grignard Reagents To Form Diarylmethyl Alkyl Ethers and Triarylmethanes
Authors: Shi Shi-Liang , Qin Yang , Liu Sheng 
Published: May 2023

AbstractWe herein report a transition-metal-free cross-coupling reaction of acetals and Grignard reagents. The method provides a modular preparation of diarylmethyl alkyl ethers, triarylmethanes, and 1,1-diarylalkanes that constitute the core structures of many bioactive molecules and synthetic motifs. A series of readily accessible acetals bearing aryl, alkenyl, and alkyl substituents efficiently coupled with commercially available aryl, alkyl, and allylic magnesium bromides to give the products in high yields. In addition to acyclic and cyclic acetals, ketal and orthoester also serve as viable substrates to afford sterically hindered tertiary ether and ketal respectively. A sequential difunctionalization of acetals led to the rapid synthesis of triarylmethanes and diarylalkanes.

Published: May 2023

AbstractTamoxifen is a selective estrogen receptor modulator and forms the mainstay of endocrine therapy in premenopausal women with breast cancer in both adjuvant and metastatic setting. Common adverse effects are menopausal symptoms with venous thrombosis and endometrial carcinoma being rarer but more sinister complications. Vasculitis is a rarely reported reaction to tamoxifen. We report a case of a 38-year-old woman with locally advanced breast cancer, who received neoadjuvant chemotherapy followed by modified radical mastectomy and adjuvant paclitaxel. She was on maintenance tamoxifen and leuprolide for 3 months, when she presented with pruritic bilateral maculopapular rash over all her limbs, legs more than hands. A skin biopsy from the left lower limb confirmed the diagnosis of vasculitis. Tamoxifen was stopped, and patient was switched to letrozole and leuprolide. She was given antihistamines, antibiotics, fusidic acid, vitamin C, and topical steroids. The lesions resolved completely in 1 month after stoppage of tamoxifen. We report this rare side effect of tamoxifen so that oncologists can effectively diagnose and treat this distressing but reversible condition.

Published: May 2023

AbstractIntroduction Epilepsy is a neurological disorder that causes neurobiological, cognitive, and psychosocial consequences. Such impairments lead to substantial social influence on women across their life cycle stages, mostly connected with stigma, the severity of illness, quality of life, and other psychosocial issues in adding to reproductive decision-making associated to risk perception. This study aimed to assess the knowledge, risk perception, and reproductive decision-making factors among women with epilepsy.Materials and Methods A cross-sectional descriptive study was carried out to assess the knowledge, risk perception, and reproductive decision-making factors among women with epilepsy. A semistructured questionnaire was prepared to collect the sociodemographic and clinical characteristics of 49 women who sought treatment for epilepsy from a national tertiary referral care center for neuropsychiatry in South India. The researcher developed a 24-item questionnaire, including three open-ended questions to assess the knowledge about reproductive health issues and epilepsy.Results The participants' mean age was 24.67 ± 3.72, where 51% had secondary education, 63.3% were married, and 46.9% were homemakers. Women with epilepsy have reported lower knowledge about the illness and about the pregnancy, childbearing practices, breastfeeding, and epilepsy-related factors. Content analysis of responses to open-ended questions brought out the presence of marriage-related concerns, epilepsy and pregnancy, misconceptions about the pregnancy outcomes, and general misconceptions about the illness factors that play a role in reproductive decision-making among women living with epilepsy.Conclusion The study reveals that women with poor knowledge about epilepsy and pregnancy have difficulty in reproductive decision-making, thereby increasing risk perception of childbearing. This places interest on the necessity for health care professionals to address the above psychosocial problems as part of their intervention plan.

Published: May 2023

AbstractThe overall outcome of head and neck cancer (HNC) patients undergoing any treatment modality may significantly depend upon their general nutritional condition. Poor nutritional status leading to sarcopenia may be a negative prognostic factor in determining the outcome of HNC patients. PubMed database was searched to identify studies published between 2015 and 2022. All studies reporting the index for sarcopenia as well as its effect on HNC were included. This narrative review was conducted to specifically evaluate the impact of sarcopenia on HNC patients undergoing surgery/ free flap reconstruction/ adjuvant treatment. In oncology, computed tomography assessment of skeletal mass at C3 and L3 is the most suitable index to detect sarcopenia. From the articles yielded, the prevalence rate of sarcopenia ranges from 6 to 70% worldwide. Indian population presents with a significantly higher rate of 31.5% sarcopenia HNC patients. Sarcopenic patients have an increased propensity for surgical site infections, as high as 24.6% owing to the reduced skeletal muscle mass. These patients are also prone to have frequent breaks during radiation treatment of more than 1 week and increased chemotherapy-related toxicities. Further, sarcopenic individuals tend to have higher Ryle's tube dependency of more than 90 days. Sarcopenic patients undergoing surgery have a poor overall survival (OS) and disease-free survival (DFS). In terms of hazards ratio, sarcopenic patients have 1.96 times poor OS and 2.00 times poor DFS when compared to normal individuals who undergo HNC surgery. Sarcopenia is an indispensable part of cancer ailment and it is an independent factor negatively influencing DFS and OS. Thus, nutritional strategy needs to be developed to mitigate sarcopenic effects, especially in the Indian population in preoperative setting.
Identifying personal physiological data risks to the Internet of Everything: the case of facial data breach risks

Published: May 2023

AbstractPersonal physiological data is the digital representation of physical features that identify individuals in the Internet of Everything environment. Such data includes characteristics of uniqueness, identification, replicability, irreversibility of damage, and relevance of information, and this data can be collected, shared, and used in a wide range of applications. As facial recognition technology has become prevalent and smarter over time, facial data associated with critical personal information poses a potential security and privacy risk of being leaked in the Internet of Everything application platform. However, current research has not identified a systematic and effective method for identifying these risks. Thus, in this study, we adopted the fault tree analysis method to identify risks. Based on the risks identified, we then listed intermediate events and basic events according to the causal logic, and drew a complete fault tree diagram of facial data breaches. The study determined that personal factors, data management and supervision absence are the three intermediate events. Furthermore, the lack of laws and regulations and the immaturity of facial recognition technology are the two major basic events leading to facial data breaches. We anticipate that this study will explain the manageability and traceability of personal physiological data during its lifecycle. In addition, this study contributes to an understanding of what risks physiological data faces in order to inform individuals of how to manage their data carefully and to guide management parties on how to formulate robust policies and regulations that can ensure data security.

AbstractThe present multi-study article investigates the subjective experience of professional football (a.k.a. soccer) referees and players during the COVID-19 pandemic and the so-called ghost games (i.e., games without supporters). Referees from the Austrian Football Association completed questionnaires inquiring about self-efficacy, motivation, and general personal observations and perceptions (e.g., arousal or confidence). In addition, two players and one referee in the Austrian Football Bundesliga were interviewed retrospectively regarding their subjective experience during ghost games and the effects of emotions on behavior and performance using semi-structured, video-taped interviews. Results of the referee survey indicate that the most profound differences between regular games and ghost games lie in the domain of intrinsic motivation and multiple aspects of subjective experience. Specifically, the experience in ghost games compared with regular games was reported by referees as being significantly less motivating, less excited/tense, less emotional, less focused, and overall, more negative, despite being easier to referee and the players behaving more positively. Qualitative analyses of the video-taped interview footage indicated (i) substantial inter-individual variability regarding the extent of the effect of the empty stadiums on the subjective experience of emotions, (ii) consequently, different strategies to regulate emotions and arousal from suboptimal to optimal levels, both before and during competition, and (iii) interactions between reported emotions, arousal, motivation, self-confidence, behavior and performance on the pitch. In addition, non-verbal expressions of emotion were captured using fully automated AI-software that coded facial movements during interviews. The results of this exploratory facial expression analysis revealed varying degrees of arousal and valence in relation to the content of the statements during the interviews, demonstrating the convergent validity of our findings. Our findings contribute to the growing literature on the effects of football games without fans during the COVID-19 pandemic and provide insights into the subjective experience of professional football referees. Concerning referees and players alike, emotions are investigated as potential processes related to home-field advantage and performance in professional football by means of a multi-methods approach. Further, the combination of qualitative and quantitative measures—as well as verbal and non-verbal communication channels—can deepen our understanding of the emotional influence of (missing) spectators on the subjective experience and the behavior of sports professionals is discussed.
A wind tunnel investigation of the unsteady aerodynamic characteristics of bionic flapping wings with three-dimensional complex motion
Authors: Li Lun , Wang Wencheng , Wu Xiaojin 
Published: May 2023

The bionic flapping wing aircraft realizes flight by imitating the structure and flapping mode of birds. In this paper, a three-dimensional composite motion aerodynamic analysis model of a bionic flapping wing is established. The diverting field and flapping wing grid are divided up using dynamic hybrid grid technology. The flow field of the flapping wing is analyzed by solving the Navier–Stokes (N–S) equation combined with the Boussinesq hypothesis. The lift of the flapping wing under different flutter frequencies and incoming wind speeds is studied under the asymmetric flutter condition. In order to verify the accuracy of the aerodynamic simulation results, a flapping-wing shrinking-ratio model prototype is made, and low-speed wind tunnel experiments are carried out to test the changes in the flight lift of the wing at different flutter frequencies and angles of attack. A comparative analysis of the wind tunnel experiment and the aerodynamic simulation results shows that when the flapping frequency (1–5 Hz) and incoming wind speed (1–5 m/s) increase, the lift force generated by the wing flapping increases. Due to the deviation between the experimental sample airfoil area and the simulated airfoil area, as well as the wing-driven fuselage vibration during the experiment, a sensor error is produced, resulting in a deviation of about 1 N between the experimental result curve and the simulation result curve. However, the aerodynamic characteristics obtained from the aerodynamic simulation analysis are basically consistent with the aerodynamic change law measured in the wind tunnel experiment.

In 2021, the World Health Organization reclassified glioblastoma, the most common form of adult brain cancer, into isocitrate dehydrogenase (IDH)-wild-type glioblastomas and grade IV IDH mutant (G4 IDHm) astrocytomas. For both tumor types, intratumoral heterogeneity is a key contributor to therapeutic failure. To better define this heterogeneity, genome-wide chromatin accessibility and transcription profiles of clinical samples of glioblastomas and G4 IDHm astrocytomas were analyzed at single-cell resolution. These profiles afforded resolution of intratumoral genetic heterogeneity, including delineation of cell-to-cell variations in distinct cell states, focal gene amplifications, as well as extrachromosomal circular DNAs. Despite differences in IDH mutation status and significant intratumoral heterogeneity, the profiled tumor cells shared a common chromatin structure defined by open regions enriched for nuclear factor 1 transcription factors (NFIA and NFIB). Silencing of
NFIA
or
NFIB
suppressed in vitro and in vivo growths of patient-derived glioblastomas and G4 IDHm astrocytoma models. These findings suggest that despite distinct genotypes and cell states, glioblastoma/G4 astrocytoma cells share dependency on core transcriptional programs, yielding an attractive platform for addressing therapeutic challenges associated with intratumoral heterogeneity.

Abstract
Gold mining land has a low level of soil fertility. One of the to increase soil fertility is the addition of micro-compost and biochar. Mycotrichocompost contains organic material enriched with microbes in the form of mycorrhizal fungi and Trichoderma therefore the organic compounds can bind to metal content. Biochar and together with organic matter can increase soil productivity as well as the retention and availability of nutrients for plants. The purpose of this study was to obtain the dose composition of mycotrichocompost and biochar in the binding of lead Pb content in ex-gold mine soil for corn planting. This research was carried out from June to September 2022. The study used a randomized group design which consisted of 2 treatments, mycotrichocompost treatment (0 tons ha−1, 5 tons ha−1, and 10 tons ha−1) and Biochar treatment (0 tons ha−1, 4 tons ha−1, 8 tons ha−1and 12 tons ha−1). The observed variables were Pb content, plant height, leaf length, number of leaves, leaf area index, and chlorophyll content. The results showed that mycotrichocompost and biochar addition showed an effect on Pb concentration, leaf length, and chlorophyll content. However, there was no relation between plant height and Leaf Area Index. This study concludes that the best treatment combination for Pb content is A3B2, leaf length is A3B2, and chlorophyll content is A3B2.

Abstract
Sugar palm is a type of palm plant, which can grow at various altitudes with different soil types. Sugar palm plants have high prospects because all parts of the plant can be used as traditional medicine, building materials, ingredients for making brown sugar, vinegar, starch, or flour, and as ingredients for various foods. In the cultivation of sugar palm plants, there are several problems found, one of which is the seeds that have a period of dormancy. The reason is the hard and impermeable seed coat that prevents water imbibition. This study aims to determine the structure and germination pattern of sugar palm seeds. This research was conducted at the Seed Technology Laboratory of the Faculty of Agriculture, Campus 3 Dharmasraya Universitas Andalas from April until September 2022. The observations obtained were the structure of the sugar palm seed consists of parts namely tip cap, testa, perisperm, endosperm, embryonic chamber, and embryo. The outer coat of the sugar palm seed is black and slippery. Each sugar palm seed has a small circle that spreads outside the seed coat where the small circle is the embryo. The duration of the sugar palm seeds’ germination from the beginning of germination until the leaves are fully open takes up to 120 days after planting.

Abstract
Peat soil has been exposed to drought so it cannot bind water (irreversible drying) and loses its function as soil. Peat soil will be dry organic soil cannot provide water to plants. In addition, drought stress as abiotic stress decreased the ability of the soil to hold roots so that plants can fall easily which is impacted by changing the physical and chemical properties of peat soil. The goal of this research was to acquire biofertilizer components that are optimized for increasing corn in drought-stress land and the sustainability of peat soils. This study was conducted inside the experimental land of Universitas Bina Insan, Lubuklinggau. The layout used in this study became a factorial randomized block design with two elements. The first element has been the biofertilizer method (F) with four stages, specifically: F0 = without mycorrhizae, F1 = Mycorrhiza + Petrobio, F2 = Mycorrhiza + Agrozeabiochar, F3 = Mycorrhiza + Pugam. The second element was the intensity of watering (P) includes 4 ranges, particularly: watering once a day, P2 = watering every three days, P3 = watering every five days, and P4 = watering every seven days. The results showed that the biofertilizer formula with mycorrhizal+petrobio (F1) treatment has significant effects in increasing plant height, plant dry weight, and nutrient uptake. Enhancement of nutrient uptake correlated with increasing the growth of corn plants on drought stress in peat soil, The intensity of watering, was significantly different in all treatments except for K nutrients uptake.
