Abstract
Antiballistics are used as personal protective equipment required by military and police personnel. They have been mentioned frequently in recent decades due to the increasing cases of war. Several studies have reviewed the development of antiballistic technology. However, there needs to be more discussion on and systematic reviews of the current milestones of antiballistic materials, testing, and procedures. In addition, compared to other fields, antiballistic studies are rarely carried out by public researchers because research on weapons is still a sensitive topic. Researchers who want to discuss antiballistics must cooperate with the country's defense and security agencies. This article aims to present a summary on and the development of scientific research on the theoretical concept of impact, the experimental approach for ballistic tests on advanced materials, the idealization of ballistic tests in computational mechanic simulations, and milestones of technical apparatus for ballistic performance measurement, over a period of more than 500 years. Thus, this analysis makes an excellent contribution to the field of antiballistics. This article review is based on hundreds of international journals and websites that are still active and can be accounted for legally. The results show that research related to antiballistics will continue to grow yearly.
Simulation evaluation of underwater robot structure and control system based on ADAMS
Authors: Tang Donglin , Li Long 
Published: June 2023

Abstract
The twenty-first century is the century of marine resources. The ocean is a treasure of biological resources, energy, water resources and mineral resources, and it would gradually become the “second space” of mankind. In the next few years, it would be more and more relevant to human life. Many scholars have realized the importance of the ocean and began to vigorously develop and use the ocean. Underwater robot is a means for human beings to explore and develop the ocean, and it would be widely used in this field. The development and promotion of underwater vehicles are of great significance to resource development, economic development, and national security. With the increasing shortage of land resources, the development and utilization of marine resources have received increasing attention. The direct exploitation of marine resources by humans would have adverse effects, so the underwater robot technology has developed rapidly in recent years. However, at present, most underwater robots are driven by electric turbines. The underwater working environment requires that the underwater motor has good sealing performance, so its structure is complex and expensive, and it is rarely used in ordinary underwater operations. In recent years, intelligent robots have been used more and more, but because of the complexity and uncertainty of the underwater working environment, there are many uncertain factors. Therefore, it is very meaningful to carry out stability control for it. The research results showed that the displacement, stability, and other corresponding test curves of each component can be obtained by establishing a simple model with software and through ADAMS (Automatic Dynamic Analysis of Mechanical Systems) simulation analysis. This can simulate the movement of real objects in the real environment and find the existing problems, so as to provide a reference for the actual underwater robot design. In this way, the development cycle and production costs can be reduced. This article analyzed the structure and control system of the underwater vehicle based on ADAMS simulation. The results showed that the dynamic stability of the underwater vehicle based on ADAMS simulation analysis was improved by 4.67% compared with the underwater vehicle before optimization.
The Family Effect: A Compass for Research on Heterogeneity of Family Businesses in Embedded Contexts
Authors: Labaki Rania , Mustafa Michael J. 
Published: June 2023

Abstract
We highlight recent research on the intertwinement of family, entrepreneurship, and strategy with a particular focus on entrepreneurial and business families. Our efforts lead us to untangle the nodal points by suggesting an interpretative framework of their main dimensions, motivators, and impacts. The family logic transcends entrepreneurial, strategic, and psychological decisions and dimensions by shaping in different ways their processes from the motivations to the outcomes. It appears, therefore, as an essential unit of study that ought to inform future research of family businesses in embedded contexts. Towards this direction, we suggest a series of theoretical and empirical route(s) along with methodological recommendations.
How Brexit Damaged the United Kingdom and the City of London
Authors: Ryan John Martin Timothy 
Published: June 2023

Abstract
This paper examines the economic cost of Brexit for the City of London. Even though the Covid pandemic may have delayed some plans for relocations by financial firms from London to the EU, the EU’s finance hubs are growing. Paris has become the bloc’s top trading hub, while Frankfurt, Dublin and Amsterdam are also emerging as hubs for different financial services specialisms. There were three drivers behind the UK government’s stance on Brexit which have been largely detrimental to City of London interests: First, Getting Brexit Done by concluding a boilerplate agreement on goods, while neglecting financial services; second, leaving the single market and ending freedom of movement making a deal on financial services impossible, and third, the false and arrogant mantra that ‘the EU needed the City more than the City needed the EU’. Prime Ministers Johnson, Truss and Sunak have led the UK into further self-inflicted economic and political decline and regulatory uncertainty. Brexit will over the next few years have a negative impact on jobs and tax receipts. The City of London will have to adapt to the harsh realities of a hard Brexit, perennial tensions with Brussels and growing competition from European financial centres and from New York.
Preventing fiber–fiber adhesion of lignin–cellulose precursors and carbon fibers with spin finish application
Authors: Bengtsson Jenny , Bengtsson Andreas , Ulmefors Hanna , Sedin Maria , Jedvert Kerstin 
Published: June 2023

AbstractAdhesion of fibers within a spun tow, including carbon fibers and precursors, is undesirable as it may interrupt the manufacturing process and entail inferior fiber properties. In this work, softwood kraft lignin was used together with a dissolving pulp to spin carbon fiber precursors. Lignin–cellulose precursors have previously been found to be prone to fiber fusion, both post-spinning and during carbon fiber conversion. In this study, the efficiency of applying different kinds of spin finishes, with respect to rendering separable precursors and carbon fibers, has been investigated. It was found that applying a cationic surfactant, and to a similar extent a nonionic surfactant, resulted in well separated lignin–cellulose precursor tows. Furthermore, the fiber separability after carbon fiber conversion was evaluated, and notably, precursors treated with a silicone-based spin finish generated the most well-separated carbon fibers. The underlying mechanism of fiber fusion post-spinning and converted carbon fibers is discussed.
Individualization of Training Based on Sprint Force-Velocity Profiles: A Conceptual Framework for Biomechanical and Technical Training Recommendations
Authors: Hicks Dylan S. , Drummond Claire , Williams Kym J. , Pickering Craig , van den Tillaar Roland 
Published: June 2023

ABSTRACT
The purpose of this article is to provide practitioners with a system to categorize and individualize training prescription from sprint force-velocity (F-v) profiles to enhance performance in team and individual sport athletes. Despite F-v variables presenting key information about the underpinning mechanisms contributing to sprint performance, the overall data interpretation may be limited for the practitioner to implement applied training interventions compared with the researcher. Therefore, this article provides a conceptual framework for appropriate training prescriptions based on individual biomechanical and technical characteristics contributing to sprint performance.

AbstractBRCA1 expression is highly regulated to prevent genomic instability and tumorigenesis. Dysregulation of BRCA1 expression correlates closely with sporadic basal‐like breast cancer and ovarian cancer. The most significant characteristic of BRCA1 regulation is periodic expression fluctuation throughout the cell cycle, which is important for the orderly progression of different DNA repair pathways throughout the various cell cycle phases and for further genomic stability. However, the underlying mechanism driving this phenomenon is poorly understood. Here, we demonstrate that RBM10‐mediated RNA alternative splicing coupled to nonsense‐mediated mRNA decay (AS‐NMD), rather than transcription, determines the periodic fluctuations in G1/S‐phase BRCA1 expression. Furthermore, AS‐NMD broadly regulates the expression of period genes, such as DNA replication‐related genes, in an uneconomical but more rapid manner. In summary, we identified an unexpected posttranscriptional mechanism distinct from canonical processes that mediates the rapid regulation of BRCA1 as well as other period gene expression during the G1/S‐phase transition and provided insights into potential targets for cancer therapy.

The purpose of this study is to analyze how user education has been carried out, and how to use the service as well as what obstacles are encountered in implementing user education in the Padangsidimpuan IAIN Library Center environment to be studied in research. This type of research is qualitative with a descriptive approach by presenting the data obtained by paying attention to the translation sentence by sentence according to the information obtained from the results of interviews, observations and documentation. The results obtained after carrying out research and analysis of the data obtained are; librarian education carried out at UPT Padangsidimpuan IAIN Library Center until the time the research was conducted was in the good category. Utilization of library services increased in the range of 40.9% after librarian education was carried out for new students. The constraints faced when carrying out librarian education included; direct visits cannot be enforced for students because the number of students is not proportional to the availability of time. Users cannot immediately browse non-printed collections because of ma'had regulations which do not allow android for new students while living in the dormitory. Inadequate infrastructure and insufficient funding for activities are separate obstacles that should be taken into consideration.Tujuan penelitian ini menganalisis bagaimana pendidikan pemustaka yang telah dilakukan, dan bagaimana pemanfaatan layanan sekaligus apa kendala yang dihadapi dalam pelaksanaan pendidikan pemustaka di lingkungan UPT Pusat Perpustakaan IAIN Padangsidimpuan menjadi kajian dalam penelitian. Jenis penelitian ini kualitatif dengan pendekatan deskriptif dengan menyajikan data yang diperoleh dengan memperhatikan penjabaran kalimat demi kalimat yang sesuai dengan informasi yang diperoleh dari hasil wawancara, observasi serta dokumentasi. Hasil yang diperoleh setelah melaksanakan penelitian dan analisis terhadap data yang diperoleh yaitu; pendidikan pemustaka yang dilaksanakan di UPT Pusat Perpustakaan IAIN Padangsidimpuan sampai pada saat penelitian dilakukan berada pada kategori baik. Pemanfaatan layanan perpustakaan meningkat pada rentang 40,9 % setelah dilaksanakan pendidikan pemustaka bagi mahasiswa baru, Kendala yang dihadapi pada saat melaksanakan pendidikan pemustaka antara lain; tidak dapat diberlakukannya kunjungan langsung bagi mahasiswa disebabkan jumlah mahasiswa tidak sebanding dengan kesediaan waktu. User tidak dapat serta merta menelusur koleksi non tercetak karena peraturan ma’had yang tidak memperbolehkan android bagi mahasiswa baru selama tinggal di asrama. Sarana prasana yang kurang memadai dan pembiayaan kegiatan yang masih kurang mencukupi menjadi kendala tersendiri yang patut jadi pertimbangan.
The paradigm shift in the later fourth millennium BC. •
Authors: Bondár Mária 
Published: June 2023

AbstractThe fourth millennium BC, particularly its second half, saw the advent of major innovations that still affect our life today, sometimes as artefacts still used in a virtually unchanged form. Among these, the most important are wheels and wheeled vehicles, the innovations introduced as part of the Secondary Products Revolution, and the new technologies of metalworking. Initially surrounded by an aura of mystique and reverence, these innovations gradually became part of everyday life and their benefits, such as a more secure livelihood engendering new subsistence strategies, were enjoyed by a growing number of communities. Better life circumstances stimulated population growth, which in turn sparked an increase in the number of settlements as well as an incipient socio-economic hierarchy between them. Improving life circumstances, receptiveness to new ideas and increasingly dynamic contacts with distant regions brought a change in previous norms and social values. This paradigm shift can be best traced in the mortuary realm: various objects signalling the status and/or prestige of a community's prominent members began to be deposited in burials. Daily life became more predictable and was accompanied by a certain measure of wealth accumulation, which, however, also stimulated frugality. Hard-to-obtain exotic commodities were highly prized and usually only their down-scaled versions fashioned from clay accompanied the dead instead of the real-life animal or prestige item. Described and briefly discussed in the present study are certain aspects of this complex process.
Raw glass and glassworking practices beyond the Roman limes: A case study of the late Roman workshop in Komarov (Middle Dniester, Western Ukraine)
Authors: Rumyantseva Olga , Trifonov Alexander , Khanin Dmitry , Chervyakovskaya Maria , Chervyakovskiy Vasiliy 
Published: June 2023

AbstractThe chemical composition of 42 samples of raw glass from the Komarov settlement on the Middle Dniester was studied by means of SEM-EDS, EPMA and LA-ICP-MS analyses. We singled out groups of colourless glass of Levantine and Egyptian origin, the chronology of which indicates that the workshop could be dated to the 4th – early 5th century. The data on the chemical composition of the raw glass do not confirm that glassmaking industry existed here in an earlier period, as was previously believed. The manufacturing in Komarov combines the use of high-quality perfectly decolourized raw glass with intensive use of cullet, which might point out either different levels of the glassware manufactured here, or selective recycling. The characteristic features of the workshop's raw glass supply are the absence of the HIMT glass and late spread of antimony-decolourized glass.
György Cziffra's Life in Hungary (1921–1956)
Authors: Cselényi Máté 
Published: June 2023

AbstractGeorges Cziffra (1921–1994) was one of the outstanding figures of Hungarian and international performing arts in the twentieth century. His adventurous life, career, fate, the virtuosity of his technical skills and his international fame have created a cult of his own, especially in recent years. However, his professional career and general biography have not yet been studied, and little to no literature has been written in the two and a half decades since his death. Thus, the reader/researcher can rely almost exclusively on his autobiography (Cannons and Flowers) and on personal reminiscences and anecdotes, which, as my research has shown, resemble a very limited extent of reality. My aim is to reconstruct and present an objective, fact-based biography in the current study, relying on the material of archives and other institutions and libraries I have collected, as well as on the complete contemporary digitized press material.
Performance Perspectives in Jenő Hubay's Violin Concertos
Authors: Pu Lihua 
Published: June 2023

AbstractJenő Hubay (1858–1937) attained his greatest stature as the founder of the Hungarian Violin School. Although Hubay's name is mostly mentioned in violin pedagogy, he was also a popular composer during his lifetime. He composed over 300 violin works, and his role as composer is underestimated unlike those of contemporaries such as Eugène Ysaÿe. The present paper focuses on the performance perspectives in Hubay's violin concertos, by examining the historical background of each concerto, followed by a systematic approach to violin and musical techniques. This includes guidelines for determining tempo, dynamics/dynamic planning, bowing/articulation, tempo rubato, and portamenti/vibrato to create a style of performance appropriate to Hubay's works.
ASYNCHRONOUS ELECTRIC MOTOR WITH SINGLE-PHASE STATOR WINDING
Authors: Байдак Юрій Вікторович 
Published: June 2023

The current standard considers the efficiency of electric motors only in terms of power efficiency and does not pay attention to the so-called economic efficiency - the power factor that affects the loss of electricity in the motor supply network and depends on its energy excellence.This ill-considered approach to establishing the energy efficiency class is a significant shortcoming of the European standard and requires its refinement. The single-phase power supply network in housing and communal services has led to the fact that modern motor compressor units of refrigerators, air conditioners, etc. are equipped with single-phase asynchronous electric motors. An innovative single-phase asynchronous AC motor for motor-compressor units of household appliances is considered in the paper. The stator winding of it is composed of two identical series-connected coils enclosed in half-slots of the stator with a spacious offset of 900.The phase shift of the currents in the coils is provided by a capacitor connected in parallel to one of the coils. The proposed motor is technological in production, has higher specific power and energy efficiency than existing models and meets the IE-3 class energy efficiency. Equivalent electrical circuit and vector diagram of currents for this motor have been developed and shown. They are intended for its mathematical simulation, calculation of static operating characteristics, analysis of dynamic properties at operation in the electric drive system, and also at the level of design work.
Quantitative sensory testing in a large cohort of neuropathy patients
Authors: Lizarraga Alexis , Bhai Salman , Wolfe Gil , Herbelin Laura , Nations Sharon , McCreary Morgan , Saperstein David , Barohn Richard 
Published: June 2023

Background:
Quantitative sensory testing (QST) is a subjective but reliable and quantifiable method to detect patient thresholds to different sensory stimuli. QST is used to measure small- and large-fiber nerve function and can be used in conjunction with other diagnostic modalities in the evaluation of peripheral neuropathy (PN). The utility of QST to distinguish among different types of PN, however, has not been explored. The objective of the study was to evaluate if different patterns of QST abnormalities could distinguish between PN types.
Methods:
This single-center retrospective cohort study evaluated the frequency of QST abnormalities to vibratory, cold and heat detection thresholds in a large population of PN cases evaluated at the University of Texas Southwestern Medical Center peripheral neuropathy clinic between 1995-2000. PN was categorized by etiology.
Results:
A total of 559 QST studies were performed in this study. The average age of patients (n=557) was 60 years with a male-to-female ratio of 1:1. The most common diagnosis was cryptogenic sensory polyneuropathy (CSPN, n=294), followed by Charcot–Marie–Tooth disease (n=84)). Meta-regression of vibration and cold indicate that the expected proportion of abnormal responses is less for the vibration test (p = 0.0002), relative to the cold test. However, no differences were observed between diagnoses.
Conclusions:
Though abnormal QST thresholds were seen in most patients with PN, patterns of QST abnormalities do not distinguish between different types of PN. The routine clinical utility of QST is likely limited.
NON-MEDICAL USE OF METHYLPHENIDATE IN MEDICAL STUDENTS IN THE MEDITERRANEAN REGION OF TÜRKİYE: A QUALITATIVE RESEARCH
Authors: YAKUT İPEKOĞLU Hilal , KOLCU Giray 
Published: June 2023

Objective
he misuse of methylphenidate is an important issue
in the relevant literature. The abuse of these drugs
for success, especially by high school and university
students, is quite common at the international level.
Young people consider these drugs as a savior in
order to be successful in the exams and to sustain
with their social life. It is possible that medical
education is very hard and stressful for students in
the world. The students feel too much pressure to
succeed. So, this situation directs students towards
alternatives that will reduce the pressure, stay awake
and focus more. This study aims to understand the
process and usage habits that direct medical students
to methylphenidate.
Material and Method
The study was designed as a qualitative research
method with an anthropological perspective. Medical
students' experiences, thoughts, and observations
on the illicit use of methylphenidate were collected
by researcher, using the in-depth interviews. The
study started with face-to-face interviews at the
end of 2019. Due to the coronavirus pandemic, the
negotiations were completed in February 2022, after
a long break. The opinions of 17 volunteer students
who participated in the study were evaluated with a
descriptive approach.
Results
According to our research findings, medical
students are positive about the non-medical use of
methylphenidate to save the day, despite its side
effects. The use of the drug increases especially
during exam periods. It is seen that drugs are as
an easy alternative for students. The medicines are
mostly provided from other friends who still use them.
In addition, the drug is also used for weight loss. It is
a fact that its effects are exaggerated and advertised
among non-prescription users. The results of our
research are similar with international ones.
Conclusion
There are very few studies on the illicit use of
psychomotor stimulants in our country. The findings
prove that medical students need healthy and
sustainable alternatives to cope with the stress and
pressure on them. It is thought that this study will be
a basis for determining the long-term negative effects
of misuse of the drugs and taking precautions. The
research is a preliminary assessment to explore the
current situation. It is clear that there is a need for
more information, quantitative and qualitative data in
the field.
