Authors: Nguyen Thi My Linh , Nguyen Cong Khanh , Vu Ngoc Ha , Nguyen Thi Hue
Published: April 2023

This study presents the survey results of 781 students of high schools in Hanoi on social cognitive competence, which is one of the four components of social intelligence. The survey results on the current situation of social cognitive capacity show that the majority of students have correct and appropriate awareness. The majority of students rated their own social cognitive performance (graded by scores) from average to good. However, there is still a significant part of high school students with incorrect and inappropriate perceptions, belonging to the group of low social-cognitive ability (14.6%). The survey results also found a number of factors that significantly affect the level of this ability of students. This result contributes to providing useful information in the development of educational programs and is a reliable database when providing educational solutions to improve the social cognitive capacity of high school students.

Authors: Nguyen Phan Lam Quyen
Published: April 2023

According to the 2018 general education program, at the primary level, the organization of experiential activities in teaching subjects plays an important role in developing students' qualities and capacities. However, in fact, the organization of experiential activities in teaching subjects in primary schools still has many shortcomings. In order for the organization of experiential activities in teaching subjects to be effective, primary school teachers must have good skills in organizing experiential activities. Because of that, the central task of the university of pedagogy is to train students' skills in organizing experiential activities in teaching subjects in order to help teachers better understand the nature of organizing activities. Experience in teaching subjects contributes to improving pedagogical capacity. This article has outlined some core theoretical issues about training skills in organizing experiential activities in teaching for students of primary education at pedagogical schools, including the issue of organizing experiential activities. in teaching, skills to organize experiential activities in teaching, and practice skills in organizing experiential activities in teaching as a scientific basis to propose activities to practice this skill to meet requirements current educational reform.

Purple corn is a cereal plant that has health benefits. Purple corn contains anthocyanins, which are useful as anticancer and antioxidants, and has high nutritional value. Improving the quality of corn production can be done through plant breeding. This study aimed to determine the value of variability, heritability and expected genetic advance of F3 purple corn from open-pollinated hybridization. The research was conducted from December 2020 to April 2021 at Universitas Bangka Belitung. The study used a single plant design experimental method. The selection used was ear to row. The results showed that the color of the seeds of the F3 line was dominated by orange. The lines have different quantitative characters. The lines that have the most purple color were F3-PXU-11-25, F3-PXU-6-16, and F3-PXU-11-20. The value of phenotypic variability and genotypic variability of the broad criteria was found in the weight of corn cob with husk and without husk. The broad heritability was high on the weight corn cob with and without husk. The value of the expected genetic advance progress of the high criteria was on the characters of cob length, the weight of 100 seeds, the weight of corn cob with husk, and the weight of corn cob without husk.

Neste artigo, fruto de pesquisa teórica, tem-se como finalidade analisar a ascensão do conceito de personalidade na Teoria da Atividade de Estudo (TAE), ao longo da história de constituição do sistema didático soviético Elkonin–Davidov–Repkin, realçando as abordagens das escolas de Moscou e de Kharkiv, com foco para as contribuições de D. B. Elkonin e V. V. Davidov para a primeira escola; e de V. V. Repkin e A. K. Dusavitskii para a segunda. O grupo de Moscou inaugura o trabalho experimental dentro dessa abordagem tendo como eixo central a compreensão do papel da escola na promoção do desenvolvimento do pensamento teórico. A personalidade não protagonizou os estudos nesta escola que avançou na investigação acerca da formação do conceito científico e das ações mentais como produto da atividade de estudo (AE), realçando a dimensão cognitiva da aprendizagem desenvolvimental. O grupo de Kharkiv, por sua vez, assume o sujeito e a personalidade como premissas e finalidades da AE e traz contribuições fundamentais para a estrutura e objetivo dessa atividade, tendo em vista levar o aluno da condição de “executor” da tarefa de estudo colocada pelo professor à condição de sujeito que pensa e coloca para si próprio a tarefa. O trabalho realizado por V. V. Repkin, A. K. Dusavitskii e os vários colaboradores que compuseram com eles a escola de Kharkiv foi crucial e representa uma importante contribuição para o estudo da personalidade na relação com a AE no contexto deste sistema didático.
LEARNING TASK AS THE HEART OF LEARNING ACTIVITY
Authors: Zuckerman Galina
Published: April 2023

A learning task introduces a situation that encourages children to search for general ways to solve a wide class of similar practical problems. The formulation and solution of the learning task involves the following actions of educators before they meet their students: 1) to perform a logical analysis of the concepts to be learned highlighting the “germ cells” - key general concepts from which the entire system of concepts describing the subject of study is derived; 2) to find a system of objects and actions with these objects, which would provide the child with a prospect to notice the essential properties of reality depicted by the concept; 3) to construct signs or symbols as the means of acting with this concept in the absence of real objects; 4) to design a situation that can lead children to posing a question, the answer to which will resolve into a new concept. When meeting with students, the teacher seeks after: 1) encouraging children for independent search for ways to solve a new problem, instead of presenting a ready-made pattern for solving such problems; 2) rousing, and then maintaining, children's initiatives aimed at the issue of their research: questions, assumptions, observations; 3) creating conditions for children’s motivation and ability to interact with their classmates so that they understand and develop each other’s suggestions about the ways to solve a new problem. When the teacher succeeds with learning tasks in the elementary school, a learning community emerges, capable and inclined to set and solve new learning tasks on their own initiative. Then later, in the middle school, most students who grew in such a community develop the learning to learn ability and the sustained drive for lifelong learning.
ORIGINS OF NATURAL SCIENCES: A TECHNOLOGICAL QUEST AS THE FIRST STEP
Authors: Vysotskaya Elena , Lobanova Anastasia D. , Yanishevskaya Maria A.
Published: April 2023

The general idea of an educational design is to deliver basic concepts (and pre-concepts) of future sciences to students, thus they will become students’ actual thinking instruments. According to Davydov, for this purpose we have to reconstruct the situation of the concept's origin and provide students’ work within this context with special modelling means (which can be, sometimes, extracted from the history of concept’s actual development). In this paper we present an overview of the introductory module of natural sciences developed according to the principles of Developmental Instruction. According to our analysis, “Nature laws” were introduced as the requirements towards human purposeful operations with “reluctant” natural material, which was transformed to special “things” (instruments, materials, supplies…) to suit human needs. As we remove the “contemporary coating” from well-known modern technologies and techniques, we will find traits of their ancient origins. Hence, we have made testing ancient technologies the foundation of our course. The whole discourse was changed: from the history of nature to the history of culture, from the actions of observing, describing and classifying to purposeful transformation and verification of hypotheses. Students’ work within the educational module includes: working over special texts, testing some fragments of technologies in hands-on experiments and constructing models. We will provide examples of students’ work over texts and labs, mediated by a special modelling tool – the technological chart.
THE MODELLING IN DEVELOPMENTAL EDUCATION: A CONDITION FOR THEORETICAL ABSTRACTION AND GENERALIZATION
Authors: Broman Anna , Waermö Mimmi , Chudinova Elena V.
Published: April 2023

The aim of the study is to explore how the modelling, as a condition for theoretical abstraction and generalization, takes shape in a certain sequence of a biology instruction based on the El’konin-Davydov Program. Research questions are: How are the students’ diagrams handled in the modelling process? What is the character and the function of the teacher’s questions and actions during the modelling process? The data consists of teachers’ lesson plans and fieldnotes related to a certain modelling carried out in several classes. Based on the results of the analysis we conclude that the students’ diagrams are used as means of the collective process of abstraction towards the generalized model. The teacher organizes and leads the modelling process so that theoretical abstraction becomes possible; thus, the students discern the general in the specific case and begin developing a theoretical concept.

Authors: Sınıcı Şükrü , Eroğlu Selma , Dündar Ümit
Published: April 2023

OBJECTIVE: Balneotherapy is a non-pharmacological method recommended and used in knee osteoarthritis. The aim of this study is to evaluate the early-term effectiveness of the physical therapy program applied together with balneotherapy in patients with knee osteoarthritis.
MATERIAL AND METHODS: Sixty patients diagnosed with primary knee osteoarthritis were included in the study. Randomization was carried out as a balneotherapy group (n=30) and a control group (n =30) by simple randomization method. In Both groups, all of the patients were treated with a fifteen sessions physical therapy program consisting of a hot pack, transcutaneous electrical stimulation, and ultrasound (1 MHz, 1,5 Watt/cm2). Patients in the balneotherapy group were also treated for fifteen sessions balneotherapy program lasting 20 min/day in addition to the physical therapy program. Patients were assessed by Visual Analogue Scale (VAS), WOMAC, and isokinetic muscle testing at the beginning and end of the therapies.
RESULTS: A statistically significant improvement was observed in the mean scores of VAS, all WOMAC scores, and isokinetic test measurements after treatment in both groups (p<0.001). Comparison of the groups by percent changes showed that; VAS (p=0.047), WOMAC pain (p=0.002), WOMAC stiffness (p=0.004), WOMAC function (p=0.001), WOMAC total (p=0.001) differed significantly in favor of balneotherapy group, no significant difference was found in isokinetic muscle strength measurements (p>0.05).
CONCLUSIONS: Balneotherapy combined with a physical therapy program in patients with knee osteoarthritis is effective in reducing pain and increasing physical function in the early period.
COVİD-19 HASTALARINDA NÖTROFİL / LENFOSİT ORANI VE VİTAMİN D DÜZEYLERİ İLE MORTALİTENİN İLİŞKİSİ
Authors: Arslan Şenol , Akın Şen İrem
Published: April 2023

AMAÇ: Koronavirüs Hastalığı 2019 (COVID-19) akut solunum yetmezliğinin eşlik ettiği ve ölümle sonuçlanabilen bir klinik tabloya yol açabilir. Her ne kadar Polimeraz Zincir Reaksiyon (PCR) testi COVID-19’un teşhisinde altın standart olsa da, hastalığın teşhisini koymak için daha hızlı ve düşük maliyetli teknikler araştırılmaktadır. Tedavi açısından ise hastaların immün sistemlerini güçlendirmeyi amaçlayan tedavi yöntemlerinin, COVID-19'un klinik seyrini hafifletmede etkili olabileceği ileri sürülmektedir. Çalışmadaki ana amacımız COVID-19 hastalarında vitamin D düzeyleri ile nötrofil/lenfosit oranı(NLR) oranlarını araştırmak ve karşılaştırmaktır. Ayrıca çalışmada COVID-19 hastalarında vitamin D ve NLR'nin mortalite için öngörücü olup olamayacağını da araştırmayı hedefliyoruz.
GEREÇ VE YÖNTEM: Retrospektif olarak yapılan bu çalışmaya acil servise başvuran, daha sonrasında yoğun bakım yatış kararı verilen 317 COVID-19 hastası alındı. Her hasta için hastadan sorumlu hekim tarafından kaydedilen bir demografik bilgi formu oluşturuldu. Hastalara ait kaydedilen verilerin hepsi vitamin D ve NLR oranları ile karşılaştırıldı.
BULGULAR: Çalışmada vitamin D düzeyleri ile COVID-19 hastalarının hastanede kalış süreleri, bilgisayarlı tomografi (BT) bulguları ve mortalitesi arasındaki ilişki incelendi. Analiz sonucunda vitamin D düzeyleri ve yukarıda bahsedilen parametreler arasında bir ilişki bulunamamıştır. Benzer şekilde NLR ile hastalarının hastanede kalış süreleri, BT bulguları ve mortalitesi arasındaki ilişki incelenmiş olup, anlamlı bir ilişki saptanmamıştır.
SONUÇ: Bu çalışmanın sonuçlarına baktığımızda vitamin D ve NLR düzeylerinin COVID-19 tanısı alan hastaların hastanede yatış süresini veya hastane içi mortalitesini öngörmede yardımcı olmadığı söylenebilir. Ancak hem vitamin D hem de NLR düzeylerinin hastanede yatış süresi ve hastane içi mortalite ile ilişkili olduğunu gösteren çalışmalarda vardır. Bu nedenle bu hipotezleri test etmek için daha fazla randomize kontrollü çalışmalar ve büyük ölçekli kohort çalışmalarının gerekli olduğunu düşünmekteyiz.

Authors: Gerik Celebi Hamıde Betul , Çam Sırrı
Published: April 2023

OBJECTIVE: Skeletal dysplasias is a complex disease group characterized by disproportionate short stature and various orthopedic complications. X-Linked Spondyloepiphyseal Dysplasia Tarda is an X-linked inherited skeletal dysplasia accompanied by progressive spondyloepi(meta)physeal dysplasia and premature osteoartritis. The gene related to the disorder is trafficking protein particle complex 2 (TRAPPC2). Progressive pseudorheumatoid dysplasia (PPRD) is characterized by enlargement of the elbow joints and arthritis-like findings. It is an autosomal recessive subtype of skeletal dysplasia caused by mutations in cellular communication network factor 6 (CCN6) gene located on chrosomal region 6q21. In this study, it was aimed to diagnose five male individuals with an X-linked or autosomal recessive inheritance pattern, who have not been diagnosed for years, to identify possible treatments and to offer prenatal pmreimplantation genetic testing.
MATERIAL AND METHODS: Five male siblings with skeletal dysplasia with an uncertain inheritance either X-linked or autosomal recessive pattern were included in this study, Whole Exome Sequencing (WES) was applied to the four affected cases. Sanger Sequencing was performed in one affected case and four healthy individuals.
RESULTS: Homozygous c.210C>A (p.Cys70Ter) and homozygous c.302G>A (p.Gly101Glu) mutations in the CCN6 gene were found in all affected siblings. Thus, the final diagnosis after WES was autosomal recessive PPRD despite the possibility of an X-linked recessive pattern.
CONCLUSIONS: This study presents a series of the oldest patients diagnosed with Progressive pseudorheumatoid dysplasia, normally a childhood disease, with an average age of 54.6. The p.Cys70Ter alteration is the most frequent pathogenic variant in Turkish patients. This study is also important in terms of showing that Progressive pseudorheumatoid dysplasia has no significant effect on life expectancy. At the same time, this study shows the progression of this disease and clinical findings that may accompany lifetime.

AMAÇ: İnfertilite tanısı almış ve karyotip analizi yapılmış 391 vaka (178 kadın, 213 erkek) grubu ve 40 çiftten oluşan kontrol grubunun kromozomal polimorfizmler açısından karşılaştırılması amaçlandı.
GEREÇ VE YÖNTEM: Vaka grubunun kromozom polimorfizmleri, arşivdeki dosyalar ve preparatlar kullanılarak retrospektif değerlendirildi. Kontrol grubuna ait kan örneklerinden kapalı lenfosit kültürü yapılarak karyotip analizi yapıldı.
BULGULAR: Toplam satellit polimorfizmleri (13 ps+,14 ps+, 15 ps+, 21 ps+ ve 22 ps+) kadın vaka grubunda kontrole göre önemli düzeyde yüksek bulundu. Vaka grubunda 1qh+, 9qh-, inv(9), 13ps+, 14ps+, 15ps+, 16qh+, 21ps+ ve 22ps+ polimorfizmlerinin dağılımlarında cinsiyetle ilişkili bir farklılık belirlenmedi. İnfertil kadınlarda en sık 9qh+ (%14,04) varyantına rastlandı. Polimorfizm 9qh+ oranı, kontrol grubuna göre vaka grubunda yüksek olmasına rağmen fark anlamsız bulundu.
SONUÇ: İnfertilite ve kromozom polimorfizmleri arasında olası bir ilişkinin varlığına dair bulgular elde edilmiş olmasına rağmen, bu ilişkinin daha net ortaya konabilmesi için örneklem sayısının artırılması ve geniş kapasiteli yeni teknolojilerin kullanıldığı çalışmaların yapılması gereklidir.
Possible Neuropathological Mechanisms Underlying the Increased Complexity of Brain Electrical Activity in Schizophrenia: A Computational Study
Authors: Khaleghi Ali , Mohammadi Mohammad Reza , Shahi Kian , Nasrabadi Ali Motie
Published: April 2023

Objective: Schizophrenia is a complex neurodevelopmental illness that is associated with different deficits in the cerebral cortex and neural networks, resulting in irregularity of brain waves. Various neuropathological hypotheses have been proposed for this irregularity that we intend to examine in this computational study.
Method: We used a mathematical model of a neuronal population based on cellular automata to examine two hypotheses about the neuropathology of schizophrenia: first, reducing neuronal stimulation thresholds to increase neuronal excitability; and second, increasing the percentage of excitatory neurons and decreasing the percentage of inhibitory neurons to increase the excitation to inhibition ratio in the neuronal population. Then, we compare the complexity of the output signals produced by the model in both cases with real healthy resting-state electroencephalogram (EEG) signals using the Lempel-Ziv complexity measure and see if these changes alter (increase or decrease) the complexity of the neuronal population dynamics.
Results: By lowering the neuronal stimulation threshold (i.e., the first hypothesis), no significant change in the pattern and amplitude of the network complexity was observed, and the model complexity was very similar to the complexity of real EEG signals (P > 0.05). However, increasing the excitation to inhibition ratio (i.e., the second hypothesis) led to significant changes in the complexity pattern of the designed network (P < 0.05). More interestingly, in this case, the complexity of the output signals of the model increased significantly compared to real healthy EEGs (P = 0.002) and the model output of the unchanged condition (P = 0.028) and the first hypothesis (P = 0.001).
Conclusion: Our computational model suggests that imbalances in the excitation to inhibition ratio in the neural network are probably the source of abnormal neuronal firing patterns and thus the cause of increased complexity of brain electrical activity in schizophrenia.

Published: April 2023

Objective: The aim of this study was to determine the role played by psychological distress in the relation between personality dimensions and pregnancy outcome of women undergoing in vitro fertilization/Intra-Cytoplasmic Injections (IVF/ICSI) treatment.
Method: This prospective cohort study was conducted for 12 months on 154 infertile women who were receiving IVF/ICSI assisted reproductive treatment for the first time. Research instruments for measuring psychological distress included the Fertility Problem Inventory (FPI) and the Depression, Anxiety, and Stress Scale (DASS-21). One of these was completed prior to ovarian stimulation and the other during the embryo transfer stage. The temperament and Character Inventory-Revised (TCI-R 125) was employed once to assess personality dimensions prior to the ovarian stimulation stage. Independent t-test, Mann Whitney test, Repeated Measures and path analysis were performed for statistical analysis of data.
Results: The results of this study showed no significant difference between the pregnant and non-pregnant groups in personality traits (Harm avoidance and self-directness) and psychological distress (FPI and DASS scores). Repeated measures showed a significant difference in stress, anxiety, and depression levels between the two stages of ovarian stimulation and embryo transfer (P < 0.01). Path analysis showed no significant direct and indirect effect for harm avoidance on the pregnancy outcome when psychological distress was mediated.
Conclusion: The effect of psychological factors on IVF outcomes is more complicated than is generally assumed and more studies are mandatory to clarify the relationship between personality traits and infertility treatments.
Uncovering Negative Interpretation Bias in Remitted/Recovered Depression with Laboratory Task
Authors: Dolatshahi Behrooz , Naderi Rajeh Yazdan , Pourshahbaz Abbas , Zarghami Mehran
Published: April 2023

Objective: Research has demonstrated that individuals with a history of depression engage in complicated strategies (e.g., thought suppression) that may mask the possible existence of major depression. Increasing the mental strain, such as retrieving a six-digit number, may reveal depressive thinking in previously depressed individuals. This study examined the hypothesis that thought suppression could mask a cognitive vulnerability to depression and illustrated how cognitive tasks disrupt mind control.
Method: This case-control study recruited 255 participants with a convenience sampling method conducted at the Razi Educational and Therapeutic Psychiatric Center (Tehran, Iran) in 2021. Participants were divided into five groups, then they were evaluated by a scrambled sentence test (SST) after random assignment to either mental load or no mental load conditions. The number of negative unscrambled statements was used as an index of negative interpretation bias. After gathering data, analysis of variance (ANOVA) for different group factors and conditions was carried out to test the main hypotheses.
Results: The effect of the intervention provided to each group on the score of the Hamilton Depression Rating Scale (HRDS) was signiﬁcant (F (4, 208) = 511.77, P < 0.001). A significant correlation (r = 0.36, P < 0.01) was found between depression (HDRS) and negative interpretive bias (SST). Analysis of ANOVA has revealed a signiﬁcant effect on the group (F (4, 412) = 14.94, P < 0.001). The effect of the mental load was not signiﬁcant (F (4, 412) = 0.09, P = 0.75), but the group × load interaction was signiﬁcant (F (4, 412) = 5.03, P < 0.001). Post hoc test was used to draw multiple comparisons between the five groups.
Conclusion: The results revealed that people who are vulnerable to depressive disorders are predominantly engaged in thought suppression, which can conceal their depressogenic thinking until cognitive requests consume their mind control efforts.

Published: April 2023

Objective: The burden on caregivers of patients with severe mental disorders is significantly higher than the care burden of patients with other medical conditions. Substance use disorder is also one of the most common psychiatric disorders that has negative effects on people's quality of life. This study was designed to investigate caregiver burden in severe mental disorders versus substance use disorder.
Method: First-degree relatives of patients admitted to the Razi Psychiatric Hospital of Tehran with a diagnosis of schizophrenia, bipolar disorder type1, schizoaffective disorder, or substance use disorder entered this study. They completed the sociodemographic questionnaire for patients and caregivers and the Zarit burden interview for caregivers.
Results: Our study shows that caregiver burden in substance use disorder has no significant difference with that in severe mental disorders (P > 0.05). In both groups, the highest spectrum of burden was moderate to severe. To find caregiver burden related factors, a general linear regression model with multiple predictor variables was fitted. In this model, caregivers’ burden was significantly higher in patients with comorbidity (P = 0.007), poor compliance (P < 0.001), and in female caregivers (P = 0.013).
Conclusion: Statistically speaking, the caregiver burden in substance use disorders is as severe as other mental disorders. The considerable burden on both groups necessitates serious efforts to minimize its negative effects.

Published: April 2023

Social stress resulting from substance abuse is a growing global concern. It is linked to mental health with psychosocial challenges faced by a large number of the populace in Nigeria. It is worrisome, especially among students in senior secondary schools in Port-Harcourt Metropolis. Thus, this research examined ‘Dialectic Behaviour Therapy and Assertiveness Training’ in managing psychosocial mental health problems of senior secondary school students who abuse substances in the Port-Harcourt metropolis. Tests before and after the study had a population of 9.650 students and employed quasi-experimental procedures. For the study, a 75-student sample from senior secondary school 2, comprised of 37 males and 38 females, was selected utilizing a multistage selection approach. Car, Relax, Alone, Forget, Family/Friends Trouble, Edinburg Mental well-being scale, and Social Phobia Inventory were the instruments utilized to collect the data. Findings revealed significant differences in the psychosocial problems of adolescents in senior secondary schools because of the interventions, however, dialectic behaviour therapy made more impact in the reduction of adolescents’ social stress though both treatments had a significant impact.

On generalized composed properties of generalized product graphs
Authors: Pleanmani Nopparat , Panma Sayan
Published: April 2023

A property ℘ is defined to be a nonempty isomorphism-closed subclass of the class of all finite simple graphs. A nonempty set S of vertices of a graph G is said to be a ℘-set of G if G[S]∈ ℘. The maximum and minimum cardinalities of a ℘-set of G are denoted by M℘(G) and m℘(G), respectively. If S is a ℘-set such that its cardinality equals M℘(G) or m℘(G), we say that S is an M℘-set or an m℘-set of G, respectively. In this paper, we not only define six types of property ℘ by the using concepts of graph product and generalized graph product, but we also obtain M℘ and m℘ of product graphs in each type and characterize its M℘-set.

Purpose — The study examines the nexus between financial liberalization and the economic growth of ECOWAS member states.Method — The longitudinal and latitudinal survey research design (expo-facto) is used in this study. Data are sourced from the World Bank and IMF Data Set for 2012-2020 and employed panel co-integration and system GMM for analyses.Result — We found that financial liberalization significantly impacts the economic growth of selected ECOWAS member countries. Similarly, the domestic economy's openness significantly impacts economic growth. While financial development exerts a positive impact, exchange rate and inflation negatively impact economic growth, the impact of interest rate is positive but insignificant.Contribution — The study provides cross-country evidence on the empirical nexus between financial liberalization and the economic growth from ECOWAS member states. To the best of authors’ knowledge, the study is one of the few studies on cross-country financial liberalization and the economic growth and used the panel data regression analysis. By this, the study covers a methodological gap, using a technique that can account for endogeneity and omitted variable problem.

Authors: Khadiev Kamil Ravilevich , Remidovsky Vladislav Sergeevich
Published: April 2023

In the framework of this work, we consider the problem of finding the largest square in a 0-1 matrix consisting of ones. The task is considered with point of view of quantum algorithms. For the problem of finding a square of the largest size on a two-dimensional map, there is a quantum algorithm with running time O(n1.5log n) and error probability at most 0.1. At the same time, any classical algorithm (probabilistic or deterministic) has a lower bound on the running time Omega(n2).
Typical metric properties of n-vertex graphs of given diameter
Authors: Fedoryaeva Tatyana Ivanovna
Published: April 2023

When studying a given class of graphs that admit the concept of dimension, i.e., a measure of their number (often, the dimension of a graph is understood as the number of its vertices; of course, there are other approaches), questions of an asymptotic nature naturally arise. In the asymptotic study of the class Ωn of graphs of dimension n, special attention is drawn to the topics around the following three questions. The first one is computing the asymptotically exact value of the number of such graphs (or obtaining good estimates for it). This makes it quite easy to calculate, as a rule, the hard-to-calculate number Ωn with a specified accuracy. The second issue is isolating or subclassing generic graphs Ωn* ⊆ Ωn for the given Ωn class. And the third is the study of general, typical properties (valid for almost all) of the graphs under consideration. This approach significantly helps to understand the structure of graphs of the entire class, especially with a large number of vertices. The report discusses the designated topic for the class of n-vertex graphs of a given diameter. We study the typical metric properties of these graphs related to the variety of metric balls, the graph radius, diametrical and central vertices, the graph center and its spectrum (the cardinality set of graph centers), etc., as well as the classes of typical graphs that arise here.

From Boolean circuits to cellular automata with locators
Authors: Gasanov Elyar Eldarovich
Published: April 2023

The report will present a new class of control systems - cellular automata with locators. The difference between cellular automata with locators and cellular automata is that cellular automata with locators can send signals on the air and receive total signals from the air. This feature allows the communication of machines, which can be arbitrarily far apart. It will be shown how such automata can be implemented as physical devices. A number of problems will be presented that can be solved fundamentally faster in a new class of control systems.

New constructions and lower bound of number of self-dual bent functions
Authors: Kutsenko Alexander Vladimirovich
Published: April 2023

The paper considers maximally non-linear Boolean functions of even number of variables - bent functions. These functions have a number applications in coding theory and cryptography. For each bent function, the dual to it bent functions. A bent function is called self-dual if it coincides with its dual. Characteristic vectors of self-dual bent functions are eigenvectors of the matrix Sylvester-Hadamard, which has applications in combinatorics, theory signals and quantum computing. The paper proposes a number of new iterative constructions of self-dual bent functions of n variables, in within which the vectors of values of bent functions from n-4 variables. Based on the analysis of sets of functions generated by data constructions, as well as previously known iterative constructions, a new iterative lower bound for the number of self-dual bent functions.

Clarification of convergence rate of distributions of quasigroup "sums" of finite random variables
Authors: Yashunsky Alexey Dmitrievich
Published: April 2023

One of the possible generalizations of sums of independent random quantities for the case of operations in a finite set -- quasi-group "sums" in which instead of the operation summation, quasi-group operations are used on a given finite set. For quasi-group "sums" containing n independent identically distributed random variables, it is proved exponential in n rate of convergence of distributions to uniform distribution.

Major depressive disorder (MDD) in adolescence seriously endangers their mental and physical health and is associated with poor social and scholastic function. However, the diagnosis and therapeutic biomarkers for adolescent with MDD remain unclear. Differential expressions of lncRNAs and mRNAs of plasma exosome were screened from 10 adolescent MDD patients and 10 healthy controls by microarray, lncRNAs-miRNAs-mRNAs networks had been generated by bioinformatic analysis, especially, 3752 differential expressions of lncRNAs and 1789 differential expression of mRNAs were included. 2 sets of axes such as AC156455.1/miR-126-5p/AAK1 and CCDC18AS1/miR-6835-5p/CCND2 were picked from networks. Candidate lncRNAs, miRNAs and mRNAs were verified in 64 adolescent MDD patients (MDD group) and 30 healthy controls (HC group) using qRT-PCR. We found that six candidate genes were differential expression between MDD group and HC group, or before and after antidepressant treatment of MDD group. The expression levels of AAK1, CCDC18AS1 and miR6835 varied in efficacy after 8-week sertraline treatment. We also found that the expression of CCDC18AS1/miR-6835-5p/CCND2 axis at baseline could predicted sertraline efficacy, which may be mediated through reducing suicidal ideation and improving cognitive function. Our study identified and validated the plasma exosome- derived lncRNAs, miRNAs and mRNAs altered in adolescent with MDD, our findings provided potential diagnosis and therapeutic biomarkers for adolescent with MDD.

Authors: Cui Xiao
Published: April 2023

The rapid development of network science and technology has promoted the popularity of streaming media technology, which makes the audio image real-time system get a rapid development. For example, it plays a great role in video monitoring and conference, and also provides a lot of support for remote assistance and other technologies, in order to realize the synchronization of teaching in music and other directions when audio can be carried out in many different scenes. At the same time, we combined with some practical projects, in this paper; we carried out the research on the implementation of cloud system for music teaching. In this process, we use asp.net platform to develop the corresponding software functions. In the process of development, the user interface and business logic analysis are designed in a systematic way. After we have initially completed the design functions of the system, we will carry out the trial run part, and then try to run again. After that, we will carry out various tests to ensure that it has perfect functions and complete codes. All the ten deployments have been sorted out and improved by the corresponding system, so as to ensure that the system platform can be used normally and give users corresponding experience. This system uses a new B / S mode, MVC mode, and SQL sever2008 as the database. Then we process the data according to the application situation and demand information of cloud system education, and find that these data give the user's needs, including the collection of various functional blocks into specific system modules.

Published: April 2023

Despite surging interest in space travel in recent decades, the impacts of prolonged, elevated exposure to galactic cosmic radiation (GCR) on human health remain poorly understood. This form of ionizing radiation causes significant changes to biological systems including damage to DNA structure by altering epigenetic phenotype with emphasis on DNA methylation. Building on previous work by Kennedy et al. (2018), we evaluated spatial DNA methylation patterns triggered by high-LET (56Fe, 28Si) and low-LET (X rays) and the influence of chromosome positioning and epigenetic architecture in distinct radial layers of cell nucleus. Next, we validated our results using gene expression data of mice and JAXA astronauts. We showed that primarily 56Fe induces a persistent DNA methylation increase whereas 28Si and X rays induce a decrease DNA methylation which is not persistent with time. Moreover, we highlighted the role of heterochromatin-associated histone modifications in absorbing GCR and protecting euchromatin-associated DNA fragments localized in inner parts of nucleus. In summary, our study provides novel insights towards epigenetic nuclear architecture and its role in limiting external radiation damage.
State-dependent auditory-reward network connectivity predicts degree of pleasure to music
Authors: Mori Kazuma , Zatorre Robert
Published: April 2023

Music can evoke pleasurable and rewarding experiences. Past studies that examined task-related brain activity revealed individual differences in musical reward sensitivity traits, and linked them to interactions between the auditory and reward systems. However, state-dependent fluctuations in spontaneous neural activity in relation to music-driven rewarding experiences have not been studied. Here, we used functional MRI (N=49) to examine whether the coupling of auditory-reward networks during a silent period immediately before music listening can predict the degree of musical rewarding experience. We used machine learning models and showed that the functional connectivity between auditory and reward networks, but not others, could robustly predict subjective, physiological, and neurobiological aspects of the strong musical reward of chills. Specifically, the right auditory cortex-striatum/orbitofrontal connections were related to neural positive arousal responses, whereas the auditory-amygdala connection was associated with physiological arousal. Moreover, the predictive model of auditory-reward network derived from one sample of individuals replicated in an independent dataset using different music samples. The current study reveals the role of pre-task brain state in efficiently connecting sensory and reward systems leading to an intensely rewarding experience.
