The life impact of mindfulness training on employees with mental anxiety disorders
Authors: Han Tao , Kang Dongwei , Han Ying , Liu Yuxuan 
Published: October 2023

BackgroundMindfulness training helps employees better cope with work and life stress by enhancing individual attention and self-awareness. At the same time, mindfulness training can help employees accept and tolerate their emotions and experiences, improve their self-efficacy and self-acceptance ability, and thus reduce anxiety.Subjects and MethodsA survey was conducted on 20 employees of a listed company in a specific city, and 20 questionnaires were collected, including 13 males and seven females. There were 6 cases with obvious anxiety symptoms, ten subjects with mild anxiety, and four without anxiety symptoms. Sixteen employees with anxiety symptoms were selected as the experimental group and received psychological intervention treatment using mindfulness training. Three months later, they were re-evaluated using the Anxiety Self Rating Scale. The effectiveness of the intervention treatment was statistically analyzed using SPSS23.0 software.ResultsAfter treatment, the experimental group of employees showed significant improvement in anxiety levels, with six recovered, eight significantly improved, and two not recovered. There was a statistically significant difference between the control and patient groups, with P values less than 0.05.ConclusionsThe overall education level of the company’s employees is relatively high, accompanied by work pressure, interpersonal relationships, and family relationships, leading to anxiety symptoms among employees. Mindfulness training can improve employees’ emotional regulation and coping abilities and promote positive emotions and psychological states.AcknowledgementSocial Science Foundation of Hebei Province (No.HB22GL037); New Liberal Arts Research and Reform Practice Project of the Ministry of Education (No.2021120010); National Natural Science Foundation of China (No.71862013).
National music culture inheritance and music education on college students’ anxiety
Authors: Huo Weiyi 
Published: October 2023

BackgroundThis study examines the impact of ethnic music culture inheritance and music education on anxiety levels among college students. Anxiety is a prevalent issue affecting college students. Exploring the potential influence of ethnic music culture and music education could provide insights into effective interventions to address anxiety among this population.Subjects and MethodsThe study involved a sample of 200 college students from different ethnic backgrounds, aged 18 to 25, studying at a university. Participants were divided into two groups: the experimental group (n=100) and the control group (n=100). The experimental group received ethnic music culture inheritance classes and music education programs, while the control group proceeded with their regular curriculum. Assessments of anxiety levels were conducted using standardized psychological scales, including the State-Trait Anxiety Inventory (STAI) and the Depression, Anxiety, and Stress Scale (DASS). The intervention period lasted for one academic semester.Results
Analysis using SPSS23.0 showed that the experimental group, which received ethnic music culture inheritance and music education, exhibited significantly lower anxiety levels compared to the control group (P<0.001). Both the STAI and DASS scores demonstrated a 30% reduction in anxiety symptoms among the experimental group, indicating the positive impact of ethnic music culture inheritance and music education on reducing anxiety among college students.Conclusions
The results show that incorporating ethnic music cultural inheritance and music education into university curricula can effectively reduce students’ anxiety levels. The integration of cultural elements and music education not only promotes the preservation of national music culture but also contributes to the mental health of students.

Published: October 2023

BackgroundAnxiety disorder is a common psychological disorder, manifested as excessive worry, fear, fear and other emotions, seriously affect the quality of life of patients. The therapeutic methods of psychological counseling include cognitive behavior therapy, interpersonal therapy, psychodynamic therapy and so on. Compared with drug treatment, psychological counseling does not produce drug dependence, fewer side effects, and good long-term effects. This study is based on psychological counseling to explore the anxiety of technical personnel in strategic emerging industries in Fujian province, China.Subjects and MethodsIn this study, 338 technical personnel in strategic emerging industries in Fujian Province were selected as the research subjects and divided into experimental groups and control groups with same number. The control group did not take any intervention measures, and the experimental group received psychological counseling. The scores of Self-rating Anxiety Scale (SAS), self-rating Depression Scale (SDS), Wechsler Adult Intelligence Test (WAIS-RC) and Health Survey Summary Form (SF-36) were compared between the two groups. T-test was performed on the measurement data.ResultsBefore the experiment, there was no significant difference in SAS and SDS scores between the two groups (P > 0.05). After the experiment, SAS and SDS scores of the experimental group were significantly lower than those of the control group (P < 0.05). The scores of verbal comprehension, memory and attention in the experimental group were significantly higher than those in the control group (P < 0.05). The scores of physiological function, mental function, mental health and vitality of the experimental group were significantly higher than those of the control group (P < 0.05).Reply: Thank you for pointing out this issue. We have rewritten the methods and results section of another article.ConclusionsPsychological counseling can effectively alleviate the anxiety of technical personnel in strategic emerging industries in Fujian Province and improve their quality of life.AcknowledgementXiamen Institute of Technology 2023 University-level Research Fund Project (No.KYZX2023028); The 2022 “I contribute good ideas to the construction of A New Fujian” (No.JAT22128).
FAITHFULNESS OF THE 2-BRAID GROUP VIA ZIGZAG ALGEBRA IN TYPE B
Authors: HENG EDMUND , NGE KIE SENG 
Published: October 2023

AbstractWe show that a certain category of bimodules over a finite-dimensional quiver algebra known as a type B zigzag algebra is a quotient category of the category of type B Soergel bimodules. This leads to an alternate proof of Rouquier’s conjecture on the faithfulness of the 2-braid groups for type B.
Freeing Chinese Men on the María Luz: Gender and the Latin American Coolie Trade
Authors: Tinsman Heidi 
Published: October 2023

AbstractThis essay analyzes a Japanese court’s criminal conviction of a Peruvian shipmaster for abusing Chinese contract workers and the subsequent release of all Chinese passengers except a lone girl. Using the case as a lens onto gender dynamics within the coolie trade to Latin America, I argue that overlapping patriarchal practices made Chinese contract labor overwhelming male and prioritized men in debates over freedom. The María Luz trials upheld women’s domestic sexual bondage while condemning men’s enslavement.
The Next American Edition of the Book of Common Prayer
Authors: Prichard Robert W. 
Published: October 2023

Abstract
The Episcopal Church has been engaged in efforts to revise its Book of Common Prayer since the mid-1990s, but a completed revision is still nowhere in sight. This essay explains the process for revision in the Episcopal Church, the working of that process leading up to the adoption of the Book of Common Prayer 1979 and the optimism about a further revision in the 1990s. It then seeks to understand the inability of the Episcopal Church to follow through on the hope of revision in the first two decades of the twenty-first century, despite considerable work on liturgical texts and the involvement of a growing number of task forces and special committees. It follows with discussion of the issues related to revision before the 2022 and the upcoming 2024 conventions and concludes with reflections on the obstacles to a completed revision.

I have accepted with pleasure the Chairman’s request to introduce our lecturer this afternoon It is twelve years ago since MR SQUIRE proved himself to be a worthy successor to the late MR H GLAUERT at the Royal Aircraft Establishment in analysing the basic aerodynamic problems of the helicopter The work of GLAUERT had been confined to vertical flight and to horizontal flight with the rotor axis vertical (like that of the Gyrodyne) MR SQUIRE extended the analysis to the flight of a helicopter in which the propulsive force for horizontal flight was obtained by a forward inclination of the rotor axis The classic report by MR SQUIRE on this subject was studied closely by the Sikorsky organisation and was put into practical effect a few years later in the well-known Sikorsky designsMR SQUIRE is recognised as the leading aerodynamicist on helicopters in this country and is Chairman of the Helicopter Committee of the Aeronautical Research Council We are all looking forward to hearing from him this afternoon on certain aerodynamic problems of the helicopter which have remained a mystery to most of us until now
The Structural Airworthiness of Helicopters with particular reference to Fatigue Failure
Authors: Garraway D R 
Published: October 2023

The importance of reliable airworthiness criteria is stressed in an introductory paragraph Practice in aeroplane design is reviewed briefly, noting particularly the current tendency to permit increasingly severe fatigue loads The principal loads on the elements of a helicopter are enumerated, and consideration of their repetitive nature leads to an extended discussion of fatigue failure and methods of correlating fatigue loads Suggestions are offered for a rationale of provisional strength requirements and the amendments desirable following the establishment of additional data The need in this connection for extensive V-g and blade stress records taken in operation is emphasisedMany people in Great Britain are now confident that helicopters will shortly be in general use for a variety of commercial purposes Some of these anticipated functions are not new to air transport undertakings—certain feeder-line services within the British Isles, for example, may well be operated by helicopters—but the fundamental ability of the helicopter to take-off and land in confined spaces gives it an additional scope in circumstances which preclude the use of fixed-wing aircraft

The Cierva “Air Horse”
Authors: Shapiro J S 
Published: October 2023

As my contribution to this afternoon’s proceedings, it is my task to give you a brief account of the Cierva “Air Horse” This machine has the distinction of being the world’s largest helicopter undergoing flight testingFollowing the recent S B A C exhibition at Farnborough, I have heard many kind and unkind expressions of expert and inexpert opinion, but the lowest common denominator seems to be that it is an “astounding contraption” Faced with this challenge, my purpose this afternoon is somewhat apologetic, namely, to show that it is neither astounding nor a contraption In fact, we, in the Cierva Autogiro Company, have persuaded ourselves that God decreed three rotor helicopters All others are merely attempts by men to cheat His divine lawsThe “Air Horse” design arose primarily as an answer to the demand for large loads It was realized that difficulties in helicopter construction increased in proportion to rotor diameter and nothing was therefore more natural than to increase the number of rotors

A theory of airflow through rotors and its application to some helicopter problems
Authors: Meijer Drees J 
Published: October 2023

The knowledge of the flow through a rotor of a rotary-wing aircraft is essential for the study of many helicopter problems The behaviour of a helicopter with respect to stability, region of roughness, etc, depends in many cases on the airflow through the disc Most existing stability or performance theories fail when they concern low forward speed and vertical descent because of some simplifying assumptionsAn attempt has been made to find a rather simple expression to describe the variations in axial velocity through a rotor as a function of the azimuth angleFurther, a chart is produced giving the average axial flow through the disc for all possible combinations of forward and vertical velocities, valid for all kinds of one-rotor aircraftThe results are used to improve the theory of some problems as mentioned above and are applied, where possible, to the Sikorsky S51 helicopter, to compare the theory with experimental data

A Regime View of ENSO Flavors Through Clustering in CMIP6 Models
Authors: Vaittinada Ayar Pradeebane , Battisti David S. , Li Camille , King Martin , Vrac Mathieu , Tjiputra Jerry 
Published: October 2023

AbstractEl Niño‐Southern Oscillation (ENSO) flavors in the tropical Pacific are studied from a regime perspective. Five recurring spatial patterns or regimes characterizing the diversity of ENSO are established using a clustering approach applied to the HadISST sea surface temperature (SST) anomalies. Compared to previous studies, our approach gives a monthly characterization of the diversity of the warm and cold phases of ENSO established from observations but commonly applied to models and observations. Two warm (eastern and central El Niño), two cold (basin wide and central La Niña) and a neutral reference regimes are found. Simulated SST anomalies by the models from the latest Coupled Model Intercomparison Project Phase 6 are then matched to these reference regimes. This allows for a consistent assessment of the skill of the models in reproducing the reference regimes over the historical period and the change in these regimes under the high‐warming Shared Socio‐economic Pathway (SSP5.8.5) scenario. Results over the historical period show that models simulate well the reference regimes with some discrepancies. Models simulate more intense and spatially extended ENSO patterns and have issues in capturing the correct regime seasonality, persistence, and transition between regimes. Some models also have difficulty simulating the frequency of regimes, the eastern El Niño regime in particular. In the future, both El Niño and central La Niña regimes are expected to be more frequent accompanied with a less frequent neutral regime. The central Pacific El Niño and La Niña regimes are projected to increase in amplitude and variability.
A Joint Perspective on North American and Euro‐Atlantic Weather Regimes
Authors: Messori Gabriele , Dorrington Joshua 
Published: October 2023

AbstractWeather regimes are recurrent and quasi‐stationary large‐scale atmospheric circulation patterns, typically linking to surface weather. Two commonly used sets of weather regimes are wintertime North American and Euro‐Atlantic regimes. Notwithstanding recent evidence pointing to a connection between winter weather in North America and Europe, there is little knowledge on the possible relation between North American and Euro‐Atlantic regimes. Here, we find that specific pairs of North American and Euro‐Atlantic regimes show a close visual and statistical correspondence. Moreover, the joint analysis of the two sets of regimes can provide medium‐range statistical predictability for anomalies in their occurrence frequencies. Conditioning on North American weather regimes also results in anomalies in both the large‐scale circulation during specific Euro‐Atlantic regimes, and the associated European surface weather. We conclude that there is a benefit in conducting joint analyses of North American and European weather regimes, as opposed to considering the two in isolation.
Generation Mechanisms of Hiss‐Like Chorus in the Earth's Magnetosphere

Published: October 2023

AbstractWhistler mode chorus waves appear either as a series of discrete elements (rising or falling tones) or as banded hiss‐like emissions in the dynamic spectrogram. Although the generation of rising‐tone chorus waves has been extensively studied, few studies have focused on the generation of hiss‐like emissions. In this paper, using the one‐dimensional (1‐D) general curvilinear particle‐in‐cell (gcPIC) simulation model, we have thoroughly studied the generation mechanisms of hiss‐like emissions. Based on the spectrogram, we first classify hiss‐like emissions into four types (I, II, III, and IV). We find that the type I hiss‐like waves are linearly excited by the anisotropic electrons, while other types are excited through the nonlinear process. For the type I waves, they do not undergo a frequency chirping process and have a relatively broadband spectrum. The high proportion of hot electrons or the large temperature anisotropy of hot electrons will decrease the threshold for nonlinear growth and cause the wave amplitudes to exceed the threshold, leading to the nonlinear generation of type II hiss‐like waves. The fresh hot electrons continually injected into the system with a large drift velocity significantly reduces the time interval between the rising tone elements to form a continuous spectrum, which are the type III waves. The intense and long‐lasting hiss‐like emissions, that is, type IV, which are the most frequently observed, should be generated due to the combined effect of the rapid injection and the high proportion of hot electrons (or the large temperature anisotropy). Our findings provide a comprehensive understanding of the generation of hiss‐like chorus waves in the Earth's magnetosphere.
Increased Population Exposure to Heat and Wet Extremes Moving From Chinese to Global 1.5 or 2.0°C Warming
Authors: Qin Peihua , Xie Zhenghui 
Published: October 2023

AbstractThe Paris Agreement proposed two global warming levels relative to the preindustrial period, with the ideal objective of 1.5°C warming and an upper boundary of 2.0 °C. However, the years when the temperature will first reach 1.5 or 2.0°C vary in different regions. Therefore, climate extremes and their population exposure are still not clear at regional or global warming levels. This study investigated climate extremes in China at different Chinese and global warming with 16 CMIP6 models under the middle SSP245 scenario. In China, the year when 1.5°C warming is projected to occur is 2020 and 2035 for 2.0°C warming. These values are more than 10 years earlier than the corresponding global warming levels of 2030 and 2049. Population exposure to percentile‐based heat extremes at global 1.5°C warming is projected to greatly increase relative to those when 1.5°C warming occurs in China due to increases in climate extremes, and exposure to absolute heat extreme indices is projected to decrease from Chinese to global 2.0°C warming under the joint impacts of increases in extremes and population decreases. Furthermore, from Chinese to global 1.5°C warming, about 344 million people will experience increased exposure to heat, wet and dry extremes, and around 468 and 371 million people will be affected by increased exposure to heat–wet and heat–dry extremes, respectively. Thus, a more adaptive strategy should be proposed to cope with the future possible natural hazards caused by heat–wet and heat–dry extremes.
