Authors: Аллахвердиева А.А. , Аллахвердиев А.Р. 
Published: July 2023

В настоящем труде представлен персонифицированный и общий групповой анализ биоэлектрической активности головного мозга (ЭЭГ) женщин 50-60 лет в геомагнитно спокойные дни и периоды гелиогеомагнитных флуктуаций. Анализировались десятисекундные лишенные артефактов отрезки электроэнцефалограмм, правой и левой гемисфер с закрытыми глазами в расслабленном состоянии и при психическом напряжении – счет в уме. Предъявляя женщинам решение арифметической задачи, мы создавали психическое напряжение. Таким образом прослеживаемая при психическом напряжении как в геомагнитно спокойные, так и периоды геомагнитных бурь перестройка показателей ЭЭГ, на смещение находящихся в балансе в покое синхронизирующих и десинхронизирующих механизмов неспецифических систем мозга в направлении активационных механизмов. В спокойные дни процессы активации высокочастотного бета ритма характеризуются локальностью, затрагивая лобные и височные отведения, в периоды с гелиогеомагнитными флуктуациями активация диффузная, затрагивающая бета-1 и бета-2 диапазоны. Диффузное уменьшение индекса и урежение частоты тета-ритма в периоды геомагнитных бурь в отличии от повышения индекса тета-ритма в дни без бурь свидетельствуют о меньшей успешности решения задачи. Ключевые слова: электроэнцефалография, частотно-амплитудный анализ, индексный анализ, психическое напряжение, женский пол, спокойные дни, слабые магнитные бури.
In the present work personalized and total group analysis of the bioelectric activity of the brain (EEG) of 50-60-year-old women on geomagnetically quiet days and periods of heliogeomagnetic fluctuations. 10-second EEG segments of the right and left hemispheres with closed eyes in a relaxed state, and with mental stress created by counting in the mind were analyzed. Mental stress was created by presenting to women an arithmetic problem to solve in the mind. Thus, the rearrangement of EEG indicators, traced under mental stress both in geomagnetically calm and periods of geomagnetic storms, indicates a shift in the synchronizing and desynchronizing mechanisms of nonspecific brain systems that are in balance at rest in the direction of activation mechanisms. On calm days, the processes of activation of the high-frequency beta rhythm are characterized by locality, affecting the frontal and temporal leads; during periods with heliogeomagnetic fluctuations, the activation is diffuse, affecting the beta-1 and beta-2 ranges. Diffuse reduction of the index and a slowing in the frequency of the theta rhythm during periods of geomagnetic storms, in contrast to the increase of the theta rhythm index on days without storms, indicate less extent of successful solution of the task.
Last mile delivery Optimisation model for drone-enabled Vehicle Routing Problem
Authors: Tausif Ismail 
Published: July 2023

In light of e-commerce's exponential growth trajectory over recent years, it has never been more critical to evaluate the last-mile delivery segment for its efficiency and cost-effectiveness. Autonomous vehicles (drones) offer considerable promise as potential solutions with ongoing investigations into emerging technologies in this context. To address problems related to last mile-delivery in logistics operations, the practicality of adopting a hybrid truck-drone delivery system is examined through this study. The researchers utilized Mixed-integer linear programming (MILP)and Gurobi optimization solvers both for optimizing performance as well as facilitating execution. While testing a drone dataset of a well-known logistics company as part of their research using an optimization model, the findings suggested that were remarkable competitive advantages including significant gains in reduction of timing. Nevertheless, there are several constraints like maintenance, recharging, difficult weather conditions & traffic congestion-necessitating focused innovative AI-based approaches. In spite of these impediments, a hybrid truck-drone’s potential applicability can remarkably boost the efficiency of last-mile delivery operations.

Language Teaching: Refashioning the Role of the English Teacher
Authors: John Smita 
Published: July 2023

Language is the unique phenomenon that man uses to communicate various life experiences, information, feelings, moods or ideas. The system of morphemes and phonemes within it make an utterance meaningful. Debates over the strategies to be implemented in the acquisition of a language have reached its zenith during the modern times. Language learning should be a natural process and proficiency in the different skills of the language is significant. Language acquisition device (LAD) and the age of the learner is significant in language learning. Proficiency in a language can vary according to the need of the learner- Second language (L2) or foreign language (FL). Different genres of literature can be used as a means to imbibe language. The role of the teacher in teaching a foreign language like English at different levels is highly demanding. Progressive modern teaching is activity based, skill oriented and demonstrative giving emphasis to uniqueness and creativity of the learner. The recent developments in Stylistics and language proposes the emergence of a new discipline. In this technologically advanced world, the role of the teacher has to be refashioned to suit the scenario. Innovative strategies should be implemented to engage the learner at graduate level so as to arouse his/her creativity to emerge successful in practical life.
Beyond the Concept of Method: Up-to-date School Language Teachers
Authors: Al-Jamal Ameen Ali Mohammed 
Published: July 2023

Prospective teachers are crammed with a good number of teaching methods while doing their courses in colleges or universities. All these methods theoretically valid. However, once teachers commence their journeys and get a room in practical classrooms, one can observe that no particular method is executed wholly, and in some circumstances these methods are not functioning well in one particular classroom or on a particular learner as every classroom is unique and every learner is unique. Teachers need to develop their own theories to be practised in classrooms as most of the proposed widespread theories and methods of teaching have been developed by professionals in their labs or universities settings, and who might never pay a visit to a classroom, especially at school level. The present paper is in response to the current affairs caused by the pandemic, Covid-19 and urges teachers in their classrooms to adopt a holistic approach to successfully manage what is happening in their classrooms or online teaching. The Covid-19 (January through September 2020) was an evaluative test to many teachers and institutes. Upon the announcement of spread of this particular pandemic, almost all schools and universities in many countries felt like paralysed, shut their classrooms and halls and even suspended the exams. Technology as a medium of teaching should have been employed from the very beginning of Covid-19 period, but teachers and institutes were not well-prepared for such a case and many could not dare to teach using online platforms. Succeeding to deliver smooth and fruitful classes in this period of time will have a positive effect in the post-covid-19 time in which a perfect blend between classroom and online learning-teaching will be practiced with ease and maximise the outcomes among learners.
KaTa Model of Learning for English Education at Higher Secondary Level in Kerala: Perspectives of a Teacher, Trainer and Curriculum Developer
Authors: Shukkoor Sajeena 
Published: July 2023

Learning English is compulsory at the higher secondary level in the State of Kerala ever since its inception. As a practising higher secondary school teacher in English, the author is replenished with the first-hand experiences of the problems of learners in classroom while learning English. The various theories of language acquisition have taken into consideration the aspects of cognitive and affective factors, natural instinct, cultural influence, etc. Though English has been compulsorily taught right from the primary level, the standards attained when they reach the higher secondary level are not up to the expectations. The author has postulated the theory of KARATE after an experimental training in Karate. Based on the results derived from this study, the author investigated the benefits of T’ai Chi another martial art, on the psycho linguistic aspects of language teachers. The author established a positive link between this martial art and language teaching. The paper examines the present conditions of English education at higher secondary level within the author’s perspective of a teacher, trainer and curriculum developer. The paper presents a KaTa model of language learning and teaching based on the findings of both studies.

Published: July 2023

A ring R is said to be strongly π-regular if for every aR there exist a positive integers n, bR such that an = an+1b. In this paper it has been proved that an abalian ring R is strongly π-regular if and only the set of all nilpotent element of R coincide with the Jacobson radical and R/J(R) is strongly-regular. In this study, some other characterizations of this kind of rings have been investigated and explored.

Authors: Li Manman , Zhang Xueqi , Zhang Tianxiang , Bai Yan , Chen Chao , Guo Donglin , Guo Changhong , Shu Yongjun 
Published: July 2023

Background
White clover (Trifolium repens L) is a high-quality forage grass with a high protein content, but it is vulnerable to cold stress, which can negatively affect its growth and development. WRKY transcription factor is a family of plant transcription factors found mainly in higher plants and plays an important role in plant growth, development, and stress response. Although WRKY transcription factors have been studied extensively in other plants, it has been less studied in white clover.

Methods and Results
In the present research, we have performed a genome-wide analysis of the WRKY gene family of white clover, in total, there were 145 members of WRKY transcription factors identified in white clover. The characterization of the TrWRKY genes was detailed, including conserved motif analysis, phylogenetic analysis, and gene duplication analysis, which have provided a better understanding of the structure and evolution of the TrWRKY genes in white clover. Meanwhile, the genetic regulation network (GRN) containing TrWRKY genes was reconstructed, and Gene Ontology (GO) annotation analysis of these function genes showed they contributed to regulation of transcription process, response to wounding, and phosphorylay signal transduction system, all of which were important processes in response to abiotic stress. To determine the TrWRKY genes function under cold stress, the RNA-seq dataset was analyzed; most of TrWRKY genes were highly upregulated in response to cold stress, particularly in the early stages of cold stress. These results were validated by qRT-PCR experiment, implying they are involved in various gene regulation pathways in response to cold stress.

Conclusion
The results of this study provide insights that will be useful for further functional analyses of TrWRKY genes in response to biotic or abiotic stresses in white clover. These findings are likely to be useful for further research on the functions of TrWRKY genes and their role in response to cold stress, which is important to understand the molecular mechanism of cold tolerance in white clover and improve its cold tolerance.

Published: July 2023

Background and aim
Efficacy of Helicobacter pylori (H. pylori) eradication is related to the local antimicrobial resistance epidemiology. We aimed to investigate the antibiotic resistance of H. pylori in Fujian, China.

Methods
H. pylori-infected patients in four centers were enrolled in the study from Oct 2019 to Jan 2022. The bacteria were isolated, cultured and identified from the biopsy of patients’ gastric mucosa samples. Antimicrobial susceptibility testing was performed by a modified broth microdilution method for H. pylori to seven guideline-recommended antibiotics and seven potential choices for H. pylori eradication.

Results
A total of 205 H. pylori strains were isolated. The resistance rates of amoxicillin (AMX), amoxicillin and clavulanate potassium (AMC), cefixime (CFM), gentamicin (GEN), tetracycline (TET), doxycycline (DOX), azithromycin (AZM), clarithromycin (CLR), levofloxacin (LVFX), sparfloxacin (SPFX), metronidazole (MTZ), tinidazole (TID), rifampicin (RFP) and furazolidone (FZD) were 11.22%, 12.20%, 7.32%, 12.20%, 4.88%, 4.39%, 44.39%, 43.90%, 30.24%, 21.46%, 40.98%, 45.85%, 5.37% and 10.24%, respectively. The rates of pan-sensitivity, single, double, triple and multiple resistance for seven guideline-recommended antibiotics were 32.68%, 30.24%, 13.17%, 7.76%, and 14.15%, respectively. The main double-resistance patterns were CLR+MTZ (10/205, 5%) and CLR+LVFX (9/205, 4%). The main triple-resistance pattern was CLR+MTZ+ LVFX (15/205, 7%).

Conclusions
In Fujian, the prevalence of H. pylori resistance to AZM, CLR, LVFX, SPFX, MTZ, and TID was high, whereas that to AMX, AMC, GEN, CFM, TET, DOX, RFP and FZD was relatively low. CFM and DOX are promising new choices for H. pylori eradication.

Published: July 2023

ImportanceInsurance coverage for patients with end-stage kidney disease has shifted toward more commercially insured patients at dialysis facilities. The associations among insurance status, facility-level payer mix, and access to kidney transplantation are unclear.ObjectiveTo determine the association of dialysis facility commercial payer mix and 1-year incidence of wait-listing for kidney transplantation, and to delineate the association of commercial insurance at the patient vs facility level.Design, Setting, and ParticipantsThis retrospective population-based cohort study used data from the United States Renal Data System from 2013 to 2018. Participants included patients aged 18 to 75 years initiating chronic dialysis between 2013 and 2017, excluding patients with a prior kidney transplant or with major contraindications to kidney transplant. Data were analyzed from August 2021 and May 2023.ExposureDialysis facility commercial payer mix, calculated as the proportion of patients with commercial insurance per facility.Main Outcomes and MeasuresThe primary outcome was patients added to a waiting list for kidney transplant within 1 year of dialysis initiation. Multivariable Cox regression, censoring for death, was used to adjust for patient-level (demographic, socioeconomic, and medical) and facility-level factors.ResultsA total of 233 003 patients (97 617 [41.9%] female patients; mean [SD] age, 58.0 [12.1] years) across 6565 facilities met inclusion criteria. Participants included 70 062 Black patients (30.1%), 42 820 Hispanic patients (18.4%), 105 368 White patients (45.2%), and 14 753 patients (6.3%) who identified as another race or ethnicity (eg, American Indian or Alaskan Native, Asian, Native Hawaiian or Pacific Islander, and multiracial). Of 6565 dialysis facilities, the mean (SD) commercial payer mix was 21.2% (15.6 percentage points). Patient-level commercial insurance was associated with increased incidence of wait-listing (adjusted hazard ratio [aHR], 1.86; 95% CI, 1.80-1.93; P &amp;lt; .001). At the facility-level and before covariate adjustment, higher commercial payer mix was associated with increased wait-listing (fourth vs first payer mix quartile [Q]: HR, 1.79; 95% CI, 1.67-1.91; P &amp;lt; .001). However, after covariate-adjustment, including adjusting for patient-level insurance status, commercial payer mix was not significantly associated with outcome (Q4 vs Q1: aHR, 1.02; 95% CI, 0.95-1.09; P = .60).Conclusions and RelevanceIn this national cohort study of patients newly initiated on chronic dialysis, although patient-level commercial insurance was associated with higher access to the kidney transplant waiting lists, there was no independent association of facility-level commercial payer mix with patients being added to waiting lists for transplant. As the landscape of insurance coverage for dialysis evolves, the potential downstream impact on access to kidney transplant should be monitored.
Comparison of dynamic tumor tracking error measurement methods for robotic radiosurgery
Authors: Okawa Kohei 
Published: July 2023

AbstractBackgroundDynamic tumor motion tracking is used in robotic radiosurgery for targets subject to respiratory motion, such as lung and liver cancers. Different methods of measuring tracking error have been reported, but the differences among these methods have not been studied, and the optimal method is unknown.PurposeThe purpose of this study was to assess and compare tracking errors encountered with individual patients using different evaluation methods for method optimization.MethodsWe compared the beam's eye view (BEV), machine learning (ML), log (addition error: AE), and log (root sum square: RSS) methods. Log (AE) and log (RSS) were calculated from log files. These tracking errors were compared, and the optimal evaluation method was ascertained. A t‐test was performed to evaluate statistically significant differences. Here, the significance level was set at 5%.ResultsThe mean values of BEV, log (AE), log (RSS), and ML were 2.87, 3.91, 2.91, and 3.74 mm, respectively. The log (AE) and ML were higher than BEV (p < 0.001), and log (RSS) was equivalent to the BEV, suggesting that the log (RSS) calculated with the log file method can substitute for the BEV calculated with the BEV method. As RSS error calculation is simpler than BEV calculation, using it may improve clinical practice throughput.ConclusionThis study clarified differences among three tracking error evaluation methods for dynamic tumor tracking radiotherapy using a robotic radiosurgery system. The log (RSS) calculated by the log file method was found to be the best alternative to BEV method, as it can calculate tracking errors more easily than the BEV method.

Published: July 2023

AbstractIn this study, novel molecular structure encoding descriptors composed of feature encoding and one‐hot encoding was developed and then convolutional autoencoder was used to denoise based on the structure of ionic liquids (ILs). It could be used to predict the CO2 solubility in ILs at different temperatures and pressures, when combined with three different machine learning algorithms (multilayer perceptron [MLP], random forest [RF], and support vector machine [SVM]). Statistics of the prediction results show that the newly proposed molecular structure‐based coding has better regression prediction performance than the conventional molecular cheminformatics descriptors. SE‐MLP model with R2 of 0.9873 and mean square error of 0.0007 has the best performance in predicting the CO2 solubility in ILs. In addition, the relationship between features and dissolved CO2 capacity was analyzed through model interpretation to retrieve physical insights for the underlying system. This work provided a new predictive tool for enriching and refining data on CO2 solubility in ILs and for solving phase equilibrium problems.
