Published: May 2024

AbstractPhonon anharmonicity plays a crucial role in determining the stability and vibrational properties of high-pressure hydrides. Furthermore, strong anharmonicity can render phonon quasiparticle picture obsolete questioning standard approaches for modeling superconductivity in these material systems. In this work, we show the effects of non-Lorentzian phonon lineshapes on the superconductivity of high-pressure solid hydrogen. We calculate the superconducting critical temperature TC ab initio considering the full phonon spectral function and show that it overall enhances the TC estimate. The anharmonicity-induced phonon softening exhibited in spectral functions increases the estimate of the critical temperature, while the broadening of phonon lines due to phonon-phonon interaction decreases it. Our calculations also reveal that superconductivity emerges in hydrogen in the Cmca − 12 molecular phase VI at pressures between 450 and 500 GPa and explain the disagreement between the previous theoretical results and experiments.

AbstractSalmonella enterica causes severe food-borne infections through contamination of the food supply chain. Its evolution has been associated with human activities, especially animal husbandry. Advances in intensive farming and global transportation have substantially reshaped the pig industry, but their impact on the evolution of associated zoonotic pathogens such as S. enterica remains unresolved. Here we investigated the population fluctuation, accumulation of antimicrobial resistance genes and international serovar Choleraesuis transmission of nine pig-enriched S. enterica populations comprising more than 9,000 genomes. Most changes were found to be attributable to the developments of the modern pig industry. All pig-enriched salmonellae experienced host transfers in pigs and/or population expansions over the past century, with pigs and pork having become the main sources of S. enterica transmissions to other hosts. Overall, our analysis revealed strong associations between the transmission of pig-enriched salmonellae and the global pork trade.

AbstractDue to climate change the pathogenic bacterium Vibrio vulnificus proliferates along brackish coastlines, posing risks to public health, tourism, and aquaculture. Here we investigated previously suggested regulation measures to reduce the prevalence of V. vulnificus, locally through seagrass and regionally through the reduction of eutrophication and consequential formation of algal blooms. Field samples collected in the summer of 2021 covered the salinity and eutrophication gradients of the Baltic Sea, one of the largest brackish areas worldwide. Physico-, biological- and hydrochemical parameters were measured and variables explaining V. vulnificus occurrence were identified by machine learning. The best V. vulnificus predictors were eutrophication-related features, such as particulate organic carbon and nitrogen, as well as occurrence of potential phytoplankton blooms and associated species. V. vulnificus abundance did not vary significantly between vegetated and non-vegetated areas. Thus, reducing nutrient inputs could be an effective method to control V. vulnificus populations in eutrophied brackish coasts.

AbstractThe prediction of suicidal thought and behavior has met with mixed results. This study of 3,476 de-identified participants (4,019 before data exclusion) quantified the prediction of four suicidal thought and behavior (STB) variables using a short reward/aversion judgment task and a limited set of demographic and mental health surveys. The focus was to produce a simple, quick and objective framework for assessing STB that might be automatable, without the use of big data. A balanced random forest classifier performed better than a Gaussian mixture model and four standard machine learning classifiers for predicting passive suicide ideation, active suicide ideation, suicide planning and planning for safety. Accuracies ranged from 78% to 92% (optimal area under the curve between 0.80 and 0.95) without overfitting, and peak performance was observed for predicting suicide planning. The relative importance of features for prediction showed distinct weighting across judgment variables, contributing between 40% and 64% to prediction per Gini scores. Mediation/moderation analyses showed that depression, anxiety, loneliness and age variables moderated the judgment variables, indicating that the interaction of judgment with mental health and demographic indices is fundamental for the high-accuracy prediction of STB. These findings suggest the feasibility of an efficient and highly scalable system for suicide assessment, without requiring psychiatric records or neural measures. The findings suggest that STB might be understood within a cognitive framework for judgment with quantitative variables whose unique constellation separates passive and active suicidal thought (ideation) from suicide planning and planning for safety.

Published: May 2024

AbstractThe emergence of topological magnetism in two-dimensional (2D) van der Waals (vdW) magnetic materials and their heterostructures is an essential ingredient for next-generation information technology devices. Here, we demonstrate the all-electric switching of the topological nature of individual magnetic objects emerging in 2D vdW heterobilayers. We show from the first principles that an external electric field modifies the vdW gap between CrTe2 and (Rh, Ti)Te2 layers and alters the underlying magnetic interactions. This enables switching between ferromagnetic skyrmions and meron pairs in the CrTe2/RhTe2 heterobilayer while it enhances the stability of frustrated antiferromagnetic merons in the CrTe2/TiTe2 heterobilayer. We envision that the electrical engineering of distinct topological magnetic solitons in a single device could pave the way for novel energy-efficient mechanisms to store and transmit information with applications in spintronics.

Published: May 2024

AbstractMore than 500 kinases are implicated in the control of most cellular process in mammals, and deregulation of their activity is linked to cancer and inflammatory disorders. 80 clinical kinase inhibitors (CKIs) have been approved for clinical use and hundreds are in various stages of development. However, CKIs inhibit other kinases in addition to the intended target(s), causing both enhanced clinical effects and undesired side effects that are only partially predictable based on in vitro selectivity profiling. Here, we report an integrative approach grounded on the use of chromatin modifications as unbiased, information-rich readouts of the functional effects of CKIs on macrophage activation. This approach exceeded the performance of transcriptome-based approaches and allowed us to identify similarities and differences among CKIs with identical intended targets, to recognize novel CKI specificities and to pinpoint CKIs that may be repurposed to control inflammation, thus supporting the utility of this strategy to improve selection and use of CKIs in clinical settings.

Published: May 2024

AbstractThis letter, proposes and experimentally demonstrates a simple and efficient estimating method for high‐voltage floating field ring (FFR). Four rings in FFR are used to determine the influence of rings’ distance (d) on the voltage drops of the highest voltage to the third ring (Vn+1) and the third to the second ring (Vn). Then, two voltage curves (curves for Vn+1 and Vn) based on d are drawn. For a target breakdown voltage, by iterating between the curves for Vn+1 and Vn, the number of FFRs and corresponding distances can be found. Based on this method, an 8.0 kV PN diode with 111 FFRs is designed and fabricated. The measured breakdown voltage is 7840 V, which reaches 98% of the designed value. This method provides a simple and efficient design for high‐voltage SiC devices, especially for ultra‐high voltage applications where the number of rings exceeds dozens.

Published: May 2024

AbstractAs the power source of the engine, the Fuel Pump(FP) plays a vital role in the safe operation of the aircraft. Due to the complexity of the working mechanism of Aviation Fuel Pumps (AFP) and the strong correlation between the components, the assessment model cannot reflect the health state of the FPs better, while the initial parameters in the assessment model will affect the assessment effect of the model. Therefore, this paper proposes a health status assessment model that can fully integrate monitoring data. To improve the accuracy of the model parameters, the Random Forest algorithm is used to give the feature weights to make up for the limitation of relying on expert knowledge, and the model parameters are optimized by the Covariance Matrix Adaptive Evolutionary Strategy algorithm, which achieves an accurate assessment of the state. Finally, the AFP test bed was built and the AFP was tested. Compared with other methods, the accuracy of the proposed method in this question reaches 96%, which is greatly superior to other methods and verifies the effectiveness of the proposed method. It also provides an outlook on future research directions for health state assessment.
A novel joint depth sensor calibration method without fixture for mobile robots’ navigation
Authors: Lu Yiming , Yuan Rupeng , Xue Tiegang 
Published: May 2024

AbstractCommercial mobile robots are usually equipped with multiple depth sensors that can measure the point cloud information around the robot's environment. The installation process of these sensors contains assembly error and sensor measurement error, so it is necessary to calibrate each sensor to align the point cloud. In order to obtain the sensor calibration results of commercial robots under normal working conditions, this study proposes a fixture free multi depth sensor joint calibration method that can be deployed on low‐cost embedded computing units, which efficiently aligns the point clouds of each sensor. During the calibration process, the robot is placed in the center of three upright thin plates perpendicular to the ground. 2D LIDAR depicts high‐precision contours of the upright thin plates. In the calibration process of each depth sensor, the roll angle and pitch angle of the sensor point cloud are first calibrated to make it perpendicular to the ground, and then the yaw angle and position of the point cloud are calibrated to fit the high‐precision contour of the upright thin plate. The results show that this method can be deployed on low‐cost embedded computing units, with real‐time and accurate calibration results. The convergence of calibration results can be achieved through up to 5 iterations, and the average running time is less than 120 ms. This research achievement provides a reference for multi‐sensor calibration of commercial robots.

Published: May 2024

AbstractWith the rising prevalence of extreme obesity, their perioperative neurosurgical management demands special attention. We report the case of an acromegalic male with a body mass index as high as 64.12 kg/m2 who presented for craniotomy and resection of a pituitary tumor under general anesthesia. Through this report, we introduce the readers to this newer concept of the highest grade of obesity in the context of neurosurgery, explain the perioperative concerns, and reiterate the need for careful drug dosing, ventilation targets, positioning requirements, thorough cardiac and airway evaluation, and preparedness for adverse events. This report also highlights the fact that a well-planned and managed case can still turn out uneventful in the presence of multiple comorbidities like diabetes mellitus, adrenocortical insufficiency, hypothyroidism, and acromegaly. Advances in airway management, regional anesthesia, and perioperative point-of-care ultrasound have made it possible to formulate a safe anesthetic plan tailored to the patient's needs.

Abstract
Introduction Hidradenitis suppurativa (HS) is a multifactorial chronic inflammatory follicular disorder affecting apocrine gland-bearing areas of the body. We conducted an observational study to assess the ultrasonography (USG) findings in suspected HS patients at a tertiary care center in North India over 6 months.
Aim The aim of this article was to study the USG findings in HS and correlate clinical and USG findings and scoring systems in HS with stage wise treatments.
Materials and Methods All patients with a clinical suspicion of HS underwent an USG examination after clinical examination with a probe of 18 Hz frequency. Hurley's staging of patients was used to stage clinically, and the HS-SOS scoring and Doppler changes were assessed on USG. The treatment was revised in case of a change in the USG grading of severity.
Results A total of 23 patients suspected of HS underwent USG evaluation, of which 12 (52%) were male and 9 (48%) were females, with the mean age being 25.3 years (range: 14–40 years). Based on the HS clinical grading, eleven patients (47.8%) were Hurley's stage I, six patients (26%) were stage II, and six patients (26%) were stage III. USG demonstrated that three patients had been misdiagnosed and had folliculitis (8.6%) and Crohn's disease (4.3%). Out of the remaining twenty patients with USG features of HS, based on HS SOS grading, three patients (15%) were grade I, seven (35%) were grade II, and ten (50%) were grade III. Of these, nineteen patients (95%) had axillary involvement, which was bilateral in 84% of cases. The other region affected was the groin in five patients (26.3%), while two had inframammary involvement (10.5%). On further characterization of the type of lesion, nodules (41; 40.6%) were the most common type of lesion by sinuses and thickened hair follicles in 31 (30.6%) patients. Based on USG findings, the management of 26% of patients was changed from medical to surgical intervention.
Conclusion USG and Doppler are noninvasive bedside tools for the examination of HS, which helps to rule out differentials and delineate the extent and depth of the disease better by picking up subclinical lesions and help in determining disease activity by Doppler, which in turn helps in planning appropriate medical and surgical management of patients. It also identifies radiological parameters that help identify patients who could fail medical management.
The Downing Street Chief-of-Staff: a case study in political management
Authors: Stafford Max W. 
Published: May 2024

AbstractThe role of Downing Street Chief-of-Staff has been neglected by examinations of British Politics, prime ministers, and political leadership and management. This is despite the role having existed since 1997. This article is a “first move” in correcting this omission. The Chief’s responsibilities are difficult to define but cover oversight of the political operation within 10 Downing Street. This includes Human Resources; “gatekeeping”; being the PM’s closest adviser; institutional reforms; and other related functions. The article uses a theoretical framework drawn from the emerging literature on political management (Lees-Marshment, in Political management: the dance of government and politics, Routledge, Abingdon, 2021) to provide an understanding of what the Chief does and why it is important that we comprehend it better. It focuses upon how chiefs have undertaken the four “D’s” (deliberating, designing, doing, and dancing) of political management and what insights can be gleaned from this evidence. Application of this framework helps to reveal key developments of chiefs’ work in a structured and detailed manner.
The moderating effect of physical exercises on job stress, emotional intelligence, and teaching satisfaction among Chinese University teachers
Authors: Zhao Mao , Yu Yating , Sin Kuen Fung 
Published: May 2024

AbstractThis study presents a conceptual model that investigates teaching satisfaction as an outcome variable in mainland China. The model incorporates the mediating mechanism of emotional intelligence and the moderating role of physical activity. The results of a survey of 2500 university teachers from 25 public institutions, which tested teaching satisfaction, demonstrate that job stress is negatively related to teaching satisfaction and indirectly related to emotional intelligence. Physical exercise acts as a moderating factor that alleviates the negative correlation between job stress and emotional intelligence. Overall, our findings indicate that enhancing the frequency of physical exercises can potentially alleviate stress, regulate emotional intelligence, and ultimately contribute to a positive enhancement in teaching satisfaction. These outcomes undeniably hold practical significance for teachers and educational administrators in the realm of higher education.
A synthesis of Kantian ethics and Rousseauvian General Will in justifying the moral ground of political laws
Authors: Lin Shuyang 
Published: May 2024

AbstractThis article explores the Kantian and Rousseauvian solutions to the conflict between autonomy and authority. First, I discuss how the categorical imperatives (CI) are the supreme source of the legitimate authority of a limited number of political laws. By extending the synthetic a priori nature of the CI, I demonstrate how Rousseau’s General Will (GW) can justify political laws in a broader sense. I also refer to the theory of H.L.A. Hart and John Rawls to show that all political laws are binding if they are within the limits of injustice and have some moral foundation. I discussed the limits of authority of on debatable laws such as banning abortion. I analyzed the possibility of GW by using Condorcet’s theorem. I conclude that GW cannot fully justify political laws based on majoritarian direct democracy, owing to problematic assumptions, although it may be an improvement to the current legislative procedure of the U.S.
Friction models of one-dimensional earthquakes
Authors: Denny Mark 
Published: May 2024

Abstract
A number of fundamental characteristics of earthquake physics are reproduced by simple stick-slip friction models. These include creep motion, stick/slip periodic earthquakes, reduced frequency of occurrence for more energetic quakes, ground velocity proportional to slip duration, and ground displacement proportional to fault length. By confining attention to one dimension, these results are obtained analytically. Though many earthquake characteristics cannot be reproduced in a one-dimensional model, our simple approach nevertheless has pedagogical value in providing insight into some of the complicated dynamics of earthquakes.

Published: May 2024

Abstract
In this paper, we address the topological characterization of the wave equation solutions in continuous two-dimensional (2D) periodic geometries with Neumann or Dirichlet boundary conditions. This characterization is relevant in the context of 2D vibrating membranes and our approach allows one to understand the topological behavior recently observed in acoustic three-dimensional artificial lattices. In particular, the dependence of the topological behavior on the experimental positioning of the coupling channels is explained using simple arguments and a simple method of construction of an equivalent effective tight-binding Hamiltonian is presented.

Abstract
According to International Commission of Radiological Protection, the equivalent dose limit for the eye lens for occupational exposure is recommended to be 20 mSv yr−1, averaged over 5 years, with no single year above 50 mSv. Some studies reported the measurement of assistant’s lens exposure in diagnostic computed tomography (CT) examinations, but further investigation is still required in the association between the lens dose for assistants and various dose parameters. Therefore, we measured the assistant’s lens exposure using small optically stimulated luminescence dosimeters. The type of occupation, type of assistance, total scan time, total mAs, total scan length, and dose-length product (DLP) were recorded and analyzed in association with air kerma at the lens position. The assistance was classified into four types: ‘assisted ventilation,’ ‘head holding,’ ‘body holding,’ and ‘raising patient’s arm.’ The air kerma of lens position was not significantly different for each assistance type (p < 0.05, Kruskal–Wallis test). Further, the lens doses for assistants correlated with DLP, but with various strengths of correlation with the assistance type and were influenced by the distance from the CT gantry. In conclusion, lens dose during assistance and DLP demonstrated the strongest correlation. ‘Raising patient’s arm’ and ‘head holding’ exhibited stronger correlations, which required less table movement during the CT scan than ‘assisted ventilation’ and ‘body holding’.
