Authors: Chávez-Ventura Gina , Santa-Cruz-Espinoza Henry , Vásquez-Olcese César , Molina-Alvarado Janeth
Published: October 2021

Para evitar la propagación de la COVID-19, muchos países ―entre ellos Perú― cerraron sus fronteras, imposibilitando el retorno de peruanos que tenían previsto volver al país y ya no contaban con recursos económicos para su manutención al haber concluido sus contratos laborales. Por ello, el propósito del estudio es caracterizar los modos de afrontamiento a la incertidumbre que experimentaron jóvenes peruanos cuando se encontraban imposibilitados de regresar a su país debido a la pandemia por COVID-19. Se diseñó un cuestionario con preguntas abiertas y cerradas, se obtuvo la validez de contenido (V= 1 [.90, 1]) y se aplicó, mediante formularios Google, a 39 jóvenes entre 19 y 26 años (M= 20.9, DE= 1.6), que cumplían su cuarentena, tras ser repatriados por el gobierno peruano. Los resultados reportan que los jóvenes se sintieron especialmente agobiados o angustiados (64.10 %) y tensos (56.41 %). Sus principales temores eran no poder regresar a Perú (43.8 %) y

contagiarse de la COVID-19 (25 %). Afrontaban el malestar durmiendo (22.81 %), realizando actividades físicas para relajarse (21.03%), recibiendo apoyo emocional de personas que recién conocían (79.49 %), y también proporcionaron apoyo a otras personas (80.95 %). Casi la totalidad de los participantes (92.31 %) realizaron acciones para intentar solucionar el problema, y el 100 % buscaba estar informado de las noticias. La mayoría (74.36 %) valoró como excitante la experiencia vivida de estar imposibilitados de poder retornar a su país. Se concluye que las principales acciones realizadas han sido para afrontar la incertidumbre emocional, cognitiva y de deseo de cambio.
Revisiting Pedagogical Variations in Service-Learning and Student Outcomes
Authors: Dahan Thomas A.
Published: October 2021

This article presents results from a quasi‐experimental replication study that extended Mabry’s 1998 correlational study by introducing a counterfactual (using psychometrically defensible measures) and controlling for academic motivation and relationships among students, faculty, and staff. The study offered evidence of the effectiveness of frequency of contact, reflection, and service duration in influencing civic and academic outcomes. Though the study’s quasi- experimental approach posed modest limitations, the measured effects were similar to those identified in Mabry’s study, thus improving confidence around findings related to the impacts of service-learning pedagogical variations and their implications for

instructional design.

Authors: Cook Amy L. , Hayden Laura A. , Bryan Julia , Belford Pamela
Published: October 2021

School counselors frequently partner with families and community organizations to promote youth development and achievement. However, challenges to implementing school-family-community partnerships often preclude developing and sustaining such relationships. In this article, the authors document the implementation of a school-family-community partnership model, which was applied across two years of collaborative counseling programming for two groups of Latina youth. Semi-structured interviews with participants, parents, and educators were conducted and analyzed using qualitative content analysis to evaluate the effectiveness of the partnership and program implementation. The authors describe the outcomes of the partnership work and counseling programming as revealed by the findings, and offer reflections and lessons learned regarding the process, including implications for school counselors.

Cellular Automaton for Kidney Branching Morphogenesis
Authors: Poorkhanalikoudehi Afshin , Zimmermann Karl-Heinz
Published: October 2021

Epithelium is a complex component in the mammalian kidney that has a highly branched duct system. Branching morphogenesis has a hierarchy structure in the ureteric bud and produces the collecting duct tree through repetitive processes. Epithelial and mesenchymal cells surround the tips of growing branches, and their cellular reactions adjust the ureteric bud branching. Mesenchymal cells produce a small protein called glial cellline derived neurotrophic factor (GDNF) that connects to te Rearranged in Transfection (RET) receptors on the surface of epithelial cells. The identified reactions are a necessity for the normal branching growth and their roles exist for using biological features in the proposed model. This paper presents an agent-based model based on cellular automaton for kidney branching in ex-vivo using the features that are expressed as artificial patterns in algorithms. This model extending the groundbreaking approach of Lambert et al. is flexible in features and high compatibility with experimental data. Mesenchymal cells and RET receptors are also expressed as mathematical patterns in the algorithms. The growth mechanism is determined by the growth factor, which indicates the epithelial cell branch when its cell division depends on the local concentration growth factor. Cell division occurs when the level of stimulus growth factor exceeds the threshold. Comparison shows that the model mimics experimental data with high consistency and reveals the dependence between growth factor parameters and features. Results indicate the superiority of compatibility with nature when compared with the model mentioned above.

In the article, the author discusses the importance of using methods of proof in an administrative case that has its own legal nature and, thus, differs from civil proof. An algorithm for proving a specific type of administrative case has been developed for the law enforcement officer, which clearly shows both the subject and the limits of proof.
Exit of the Court Beyond the Stated Requirements when Considering Cases from Civil, Family and Labor Relations
Authors:   North-West Branch of the Russian State University of Justice (St. Petersburg), O. Yu. Malkin , L. A. Smolina
Published: October 2021

The article considers the grounds for the court to go beyond the stated requirements when resolving cases from civil, family and labor relations. It is shown that going beyond the stated requirements is possible both in the civil and in the arbitration process. At the same time, non-fulfillment or improper fulfillment by the court of the obligation assigned to it to resolve certain issues may lead to a violation of the rights and interests of the parties to the dispute, to the annulment of the court order. The aim of the study was to develop recommendations for improving the practice of applying the provisions of the law on the court going beyond the stated requirements. The objectives of the study were to differentiate the grounds for the court to go beyond the stated requirements with related situations; classification of cases of non-application or improper application by the court of going beyond the stated requirements; identifying ways to eliminate the violations if the court goes beyond the stated requirements. The consideration of problems associated with going beyond the stated requirements is based on general scientific research methods (formal logic method) involving industry methods (comparative study methods of arbitration and civil processes, system analysis of positive legal material), which together ensured the reliability of the results of the work. In order to correctly use the mechanism by the court to go beyond the stated requirements, to prevent and eliminate violations of the rights and interests of the parties to the dispute in such situations, the authors proposed: 2. to differentiate between the court’s withdrawal beyond the stated requirements and the situation when the court changes the wording of the claimed claim in the operative part of the decision, brings it into line with the law, and also satisfies the interest of the defendant in the court when the plaintiff’s claim itself implied this; 3. the Supreme Court of the Russian Federation to clarify in the decisions of the Plenum, in reviews of judicial practice, cases of a court going beyond the stated requirements when considering civil, family and labor disputes, limiting the arbitrary discretion of lower courts; 4. the ways to eliminate violations of the rights and interests of the parties to the dispute when the court goes beyond the stated requirements are the adoption of an additional decision, appeal of the court decision, as well as an independent claim.
Continuity of Justice: COVID-19 Judicial Isolation Lessons
Authors:   Russian State University of Justice (Moscow), Burdina E. V. , Chizhov M. V.
Published: October 2021

Formulation of the Problem. COVID-19 has changed the legal being and functioning of the justice system. The main purpose of the judiciary was threatened – to provide everyone with a means to protect their rights, to be available to protect justice. The formulation of promising tasks of the judicial system is possible both taking into account the outcome of judicial isolation, and in the context of radically changed economic and social realities after the epidemic. Purpose of the Work: on the basis of the analysis of the activity of courts of different law and order under the restrictions associated with COVID-19, to formulate theoretical and practical conclusions aimed at maintaining the uninterrupted administration of justice and judicial activity in the modern conditions of the information society. Methods. The methodological base consists of traditional techniques and methods of scientific knowledge (dialectical, logical, system analysis, comparative legal, etc.). Results, Brief Conclusions. Classic legal perceptions of justice and the judiciary are undergoing paradigm shifts as a result of recognition of the value of the outcome of the Fourth Industrial Revolution and digital technology. The present period is the period of the methodological search for the balance and stability of judicial institutions in the changed realities. In the framework of theoretical and legal modeling of the justice system, the terminological apparatus of the judiciary needs to rethink, since many traditional concepts, under the influence of digitalization and social grounds, transform or expand their content. The author offers a look at the problems of defining the term «e-justice», the problems of increasing demand for justice and the adaptation of digital technologies to the needs of the judiciary.
Some Problematic Issues of Judicial Protection of Copyright and Related Rights Violated in the Information and Telecommunications Network
Authors:   Russian State University of Justice (Moscow), N. V. Buzova
Published: October 2021

Russian legislation provides for measures of civil protection of infringed intellectual property rights. Protection measures include, for example, restricting access or deleting materials that are used in information and telecommunication networks, including the Internet, if such use violates copyright or related rights. During the period of application of the legislation concerning the protection of copyright and related rights violated in information and telecommunication networks, certain judicial practice has already been formed and certain approaches have been developed. But the introduction of new technologies, the use of new services in information and telecommunication networks creates new uncertainties. The purpose of this article is to identify problematic aspects that require not only additional theoretical research, but also, possibly, changes in legislation. Based on the analysis of the legislation on intellectual property and information protection, as well as judicial practice, some problematic issues have been identified that arise in judicial consideration of cases related to copyright and related rights infringement. Problematic issues include, in particular, the use without the permission of the copyright holder of copyright and related rights objects placed in cloud services, indication in judicial decisions of the domain name of the website or other network resource, the possibility of an unlimited ban on placement on a certain website or other network resource of the object copyright and related rights.

Combined (Visual-Verbal) Investigative Actions: Legal Nature and Significance for Proof
Authors:   Ural Law Institute of the Ministry of the Interior of Russia (Yekaterinburg), V. Yu. Stel'makh
Published: October 2021

Russian criminal procedure legislation provides for investigative actions based on a combined combination of visual and verbal perception. At the theoretical level, to date, some problems of the evidentiary significance of the results of these investigative actions and their place in evidence in a criminal case have not been solved. The aim of the study is to develop an optimal theoretical model for using combined investigative actions in proving the results. The objectives of the study are: to analyze the legal nature of these actions, to distinguish elements of visual and verbal perception in their structure, to identify the possibility of removing material objects during the investigative actions under consideration, to establish the possibility of announcing the protocols of investigative actions in a court hearing. The study is based on the dialectical-materialistic general method, which involves the study of phenomena in systemic communication and totality, as well as on general scientific methods of analysis and synthesis, induction and deduction, and private-legal methods. Results of the Study. A distinction was made between the ratio of visual and verbal components in various investigative actions. Based on this, it was concluded that material objects could be removed as part of the verification of evidence on the spot, and this was impossible during the investigative experiment and verification of evidence on the spot. It is stated that the information provided in the course of conducting the investigated investigative actions verbally does not relate to the testimony. The results of all the indicated investigative actions in terms of the types of evidence are minutes and are subject to announcement at the court hearing, regardless of the existence of conditions established by law for the announcement of evidence. The results of combined investigative actions have important evidentiary significance in the paradigm of a mixed type of criminal process. The author believes that this type of proceedings is optimal, which requires an improvement in the regulatory design of combined investigative actions.

This article aims to explore the theology of minjung. It is an accumulation and articulation of theological reflections on the political experience of Christian students, laborers, the press, professors, farmers, writers, and intellectuals as well as theologians in Korea in the 1970s. Minjung theology of Korea has been known as a branch of liberation theology. However, minjung theology was born in a special situation in Korea and has distinctive features from liberation theology. Through this research, I examine the definition, background, and characteristics of minjung theology, and attempts to research reconciliation, an important topic of modern theology, from the perspective of minjung theology. Minjung is economically poor, politically weak, socially deprived, but culturally and historically rich and powerful. Also, minjung, the poor, can think. They can do theology. There is no need for them to depend upon their oppressors to tell them what the gospel is.

Published: October 2021

Background: We studied whether musclin function in humans is related to glycemic control, body composition, and cardiorespiratory capacity.Methods: A cross-sectional study was performed in sedentary adults with or without metabolic syndrome (MS). Serum musclin was measured by enzyme-linked immunosorbent assay. Insulin resistance (IR) was evaluated by the homeostatic model assessment (HOMA-IR). Body composition was determined by dual-energy X-ray absorptiometry and muscle composition by measuring carnosine in the thigh, a surrogate of fiber types, through proton magnetic resonance spectroscopy. Cardiorespiratory capacity was assessed through direct ergospirometry.Results: The control (n=29) and MS (n=61) groups were comparable in age (51.5±6.5 years old vs. 50.7±6.1 years old), sex (72.4% vs. 70.5% women), total lean mass (58.5%±7.4% vs. 57.3%±6.8%), and peak oxygen consumption (VOpeak) (31.0±5.8 mL O2./kg.min vs. 29.2±6.3 mL O2/kg.min). Individuals with MS had higher body mass index (BMI) (30.6±4.0 kg/m2 vs. 27.4± 3.6 kg/m2), HOMA-IR (3.5 [95% confidence interval, CI, 2.9 to 4.6] vs. 1.7 [95% CI, 1.1 to 2.0]), and musclin (206.7 pg/mL [95% CI, 122.7 to 387.8] vs. 111.1 pg/mL [95% CI, 63.2 to 218.5]) values than controls (P˂0.05). Musclin showed a significant relationship with HOMA-IR (β=0.23; 95% CI, 0.12 to 0.33; P˂0.01), but not with VOpeak, in multiple linear regression models adjusted for age, sex, fat mass, lean mass, and physical activity. Musclin was significantly associated with insulin, glycemia, visceral fat, and regional muscle mass, but not with BMI, VCO2peak, maximum heart rate, maximum time of work, or carnosine.Conclusion: In humans, musclin positively correlates with insulinemia, IR, and a body composition profile with high visceral adiposity and lean mass, but low body fat percentage. Musclin is not related to BMI or cardiorespiratory capacity.

Published: October 2021

Background: Conventional diagnostic approaches for adrenal tumors require multi-step processes, including imaging studies and dynamic hormone tests. Therefore, this study aimed to discriminate adrenal tumors from a single blood sample based on the combination of liquid chromatography-mass spectrometry (LC-MS) and machine learning algorithms in serum profiling of adrenal steroids.Methods: The LC-MS-based steroid profiling was applied to serum samples obtained from patients with nonfunctioning adenoma (NFA, n=73), Cushing’s syndrome (CS, n=30), and primary aldosteronism (PA, n=40) in a prospective multicenter study of adrenal disease. The decision tree (DT), random forest (RF), and extreme gradient boost (XGBoost) were performed to categorize the subtypes of adrenal tumors.Results: The CS group showed higher serum levels of 11-deoxycortisol than the NFA group, and increased levels of tetrahydrocortisone (THE), 20α-dihydrocortisol, and 6β-hydroxycortisol were found in the PA group. However, the CS group showed lower levels of dehydroepiandrosterone (DHEA) and its sulfate derivative (DHEA-S) than both the NFA and PA groups. Patients with PA expressed higher serum 18-hydroxycortisol and DHEA but lower THE than NFA patients. The balanced accuracies of DT, RF, and XGBoost for classifying each type were 78%, 96%, and 97%, respectively. In receiver operating characteristics (ROC) analysis for CS, XGBoost, and RF showed a significantly greater diagnostic power than the DT. However, in ROC analysis for PA, only RF exhibited better diagnostic performance than DT.Conclusion: The combination of LC-MS-based steroid profiling with machine learning algorithms could be a promising one-step diagnostic approach for the classification of adrenal tumor subtypes.

Published: October 2021

It has been suggested that the coronavirus disease 2019 (COVID-19) pandemic has had a negative impact on glycemic control in patients with type 2 diabetes mellitus (T2DM). However, no study has examined yearly trends in glycated hemoglobin (HbA1c) levels after the start of the COVID-19 outbreak. Here, we performed a retrospective analysis of HbA1c concentrations during the early period of the COVID-19 outbreak (COVID-19 cohort) and then compared the yearly trend in the mean HbA1c level, along with fluctuations in HbA1c levels, with those during previous years (non-COVID-19 cohorts). We observed that the mean HbA1c level in patients with T2DM increased during the first 6 months of the COVID-19 outbreak. After 6 months, HbA1c levels in the COVID-19 cohort returned to levels seen in the non-COVID-19 cohorts. The data suggest that vulnerable patients with T2DM should be monitored closely during the early period of a pandemic to ensure they receive appropriate care.

Authors: Kim Ki-Hun , Lee Juhui , Ahn Chang Ho , Yu Hyeong Won , Choi June Young , Lee Ho-Young , Lee Won Woo , Moon Jae Hoon
Published: October 2021

Background: Heart rate (HR) monitored by a wearable device (WD) has demonstrated its clinical feasibility for thyrotoxicosis subjects. However, the association of HR monitored by wearables with hypothyroidism has not been examined. We assessed the association between serum thyroid hormone concentration and three WD-HR parameters in hypothyroid subjects.Methods: Forty-four subjects scheduled for radioactive iodine therapy (RAI Tx) after thyroid cancer surgery were included. Thirty subjects were prepared for RAI Tx by thyroid hormone withdrawal (hypothyroidism group) and 14 subjects by recombinant human thyrotropin (control group). Three WD-HR parameters were calculated from the HR data collected during rest, during sleep, and from 2:00 AM to 6:00 AM, respectively. We analyzed the changes in conventionally measured resting HR (On-site rHR) and WDHR parameters relative to thyroid hormone levels.Results: Serum free thyroxine (T4) levels, On-site rHR, and WD-HR parameters were lower in the hypothyroid group than in the control group at the time of RAI Tx. WD-HR parameters also reflected minute changes in free T4 levels. A decrease in On-site rHR and WD-HR parameters by one standard deviation (On-site rHR, approximately 12 bpm; WD-HR parameters, approximately 8 bpm) was associated with a 0.2 ng/dL decrease in free T4 levels (P<0.01) and a 2-fold increase of the odds ratio of hypothyroidism (P<0.01). WD-HR parameters displayed a better goodness-of-fit measure (lower quasi-information criterion value) than On-site rHR in predicting the hypothyroidism.Conclusion: This study identified WD-HR parameters as informative and easy-to-measure biomarkers to predict hypothyroidism.
Frequency of Exposure to Impaired Fasting Glucose and Risk of Mortality and Cardiovascular Outcomes
Authors: Lee Seung-Hwan , Han Kyungdo , Kwon Hyuk-Sang , Kim Mee Kyoung
Published: October 2021

Background: Metabolic abnormalities, such as impaired fasting glucose (IFG), are dynamic phenomena; however, it is unclear whether the timing of IFG exposure and cumulative exposure to IFG are related to cardiovascular disease (CVD) and mortality risk.Methods: Data were extracted from a nationwide population-based cohort in South Korea for adults (n=2,206,679) who were free of diabetes and had 4 years of consecutive health examination data. Fasting blood glucose levels of 100 to 125 mg/dL were defined as IFG, and the number of IFG diagnoses for each adult in the 4-year period was tabulated as the IFG exposure score (range, 0 to 4). Adults with persistent IFG for the 4-year period received a score of 4.Results: The median follow-up was 8.2 years. There were 24,820 deaths, 13,502 cases of stroke, and 13,057 cases of myocardial infarction (MI). IFG exposure scores of 1, 2, 3, and 4 were associated with all-cause mortality (multivariable-adjusted hazard ratio [aHR], 1.11; 95% confidence interval [CI], 1.08 to 1.15; aHR, 1.16; 95% CI, 1.12 to 1.20; aHR, 1.20; 95% CI, 1.15 to 1.25; aHR, 1.18; 95% CI, 1.11 to 1.25, respectively) compared with an IFG exposure score of 0. Adjusting for hypertension and dyslipidemia attenuated the slightly increased risk of MI or stroke associated with high IFG exposure scores, but significant associations for allcause mortality remained.Conclusion: The intensity of IFG exposure was associated with an elevated risk of all-cause mortality, independent of cardiovascular risk factors. The association between IFG exposure and CVD risk was largely mediated by the coexistence of dyslipidemia and hypertension.

Agri-food export and its development are an important area of economic policy in our country. In recent years, its dynamics have been impressive. In this regard, the main factors providing its positive dynamics are of interest. It is also important to assess the impact of the pandemic shock, including changes in migration processes, as well as export restrictions that were introduced in 2020. They remain in effect in the current period. How these factors can affect in the short and long term and what alternative solutions exist is of practical and theoretical interest.
Relation of Microstreams in the Polar Solar Wind to Switchbacks and Coronal X-Ray Jets
Authors: Neugebauer Marcia , Sterling Alphonse C.
Published: October 2021

Ulysses data obtained at high solar latitudes during periods of minimum solar activity in 1994 and 2007 are examined to determine the relation between velocity structures called microstreams and folds in the magnetic field called switchbacks. A high correlation is found. The possibility of velocity peaks in microstreams originating from coronal X-ray jets is reexamined; we now suggest that microstreams are the consequence of the alternation of patches of switchbacks and quiet periods, where the switchbacks could be generated by minifilament/flux rope eruptions that cause coronal jets.
Investigating Protoplanetary Disk Cooling through Kinematics: Analytical GI Wiggle
Authors: Longarini Cristiano , Lodato Giuseppe , Toci Claudia , Veronesi Benedetta , Hall Cassandra , Dong Ruobing , Patrick Terry Jason
Published: October 2021

It is likely that young protostellar disks undergo a self-gravitating phase. Such systems are characterized by the presence of a spiral pattern that can be either in a quasi-steady state or in a nonlinear unstable condition. This spiral wave affects both the gas dynamics and kinematics, resulting in deviations from the Keplerian rotation. Recently, a lot of attention has been devoted to kinematic studies of planet-forming environments, and we are now able to measure even small perturbations of velocity field (≲1% of the Keplerian speed) thanks to high spatial and spectral resolution observations of protostellar disks. In this work, we investigate the kinematic signatures of gravitational instability: we perform an analytical study of the linear response of a self-gravitating disk to a spiral-like perturbation, focusing our attention on the velocity field perturbations. We show that unstable disks have clear kinematic imprints into the gas component across the entire disk extent, due to the GI spiral wave perturbation, resulting in deviations from Keplerian rotation. The shape of these signatures depends on several parameters, but they are significantly affected by the cooling factor: by detecting these features, we can put constraints on protoplanetary disk cooling.
The Exploration of Antenatal Education Method and its Problems in Denpasar Regency, Indonesia: A Qualitative Study
Authors: Wayan Ariyani , Ady Wirawan I. Made , Indraguna Pinatih Gede Ngurah , Jaya Kusuma Anak Agung Ngurah
Published: October 2021

BACKGROUND: Antenatal education is a process giving health information to pregnant women as a part of antenatal care. Antenatal education influences knowledge and behavior which indirectly give impact to the health of mothers and children. In implementing several antenatal education methods, several countries have experienced some obstacles.

AIM: The present study aimed to explore the implementation and problems of antenatal education in Denpasar Bali.

METHODS: Descriptive qualitative exploration design was used in the study. The respondents were ten midwives in primary health-care clinics and private midwifery clinics in all districts of Denpasar city. The sample was selected using purposive sampling. Data analysis was using thematic approach by QSR Nvivo 12 Plus.

RESULTS: The result of this study found two main themes; those were maternity class method and individual/face to face method. Midwives reported that on maternity class method the delivered information was felt more complete since it was in accordance with curriculum, pregnant women could hare with each other, and they could integrate with other professions. However, its weakness was low participation of pregnant women due to busyness. Meanwhile, face-to-face method had advantages since pregnant women felt free to express their personal problems and midwives could offer solutions for the identified problems during antenatal visits. Nevertheless, it has many disadvantages such as, very limited information was provided, problem with human resource management, time management, and pregnant women visitation management.

CONCLUSION: In conclusion, both of antenatal education methods have advantages and disadvantges. Maternity class method is considered as a better method yet pregnant women participation to the class is relatively low. Face-to-face method is considered not comprehensive in delivering antenatal information as its problem with time management, human resource management, and patient management.

Published: October 2021

The current mixed methods, exploratory study aimed to develop and determine the psychometrics of a scale to assess the spiritual needs of patients with coronavirus disease 2019 (COVID-19). The study was performed in two stages: qualitative and quantitative. Through 14 interviews with patients with COVID-19, three themes, including
Composure
,
Meaning in Life
, and
Global Responsibility
, were formed. In the quantitative stage, content validity was achieved through the comments of 10 experts and patients. A total of 330 participants completed the instrument to assess construct validity. Exploratory factor analysis with 29 items and four subscales was performed, indicating a 6-point Likert scale. Cronbach's alpha coefficients ranged from 0.82 for the whole scale and 0.85, 0.81, 0.79, and 0.72 for the Composure, Communication, Meaning in Life, and Global Responsibility subscales, respectively. Intraclass correlation coefficient (test–retest analysis) was 0.79 and showed acceptable stability for the scale. The “Spiritual Needs Assessment Scale for COVID-19 Patients” is a 29-item multi-dimensional scale with robust psychometric properties, which can measure various aspects regarding the spiritual needs of patients with COVID-19.

Trajectory statistical solutions for the Cahn-Hilliard-Navier-Stokes system with moving contact lines
Authors: You Bo
Published: October 2021

The objective of this paper is to consider the long-time behavior of solutions for the Cahn-Hilliard-Navier-Stokes system with moving contact lines. As we know, it is very difficult to obtain the uniqueness of an energy solution for this system even in two dimensions caused by the presence of the strong coupling at the boundary. Thus, we first prove the existence of a trajectory attractor for such system, which is a minimal compact trajectory attracting set for the natural translation semigroup defined on the trajectory space. Furthermore, based on the abstract results (trajectory attractor approach) developed in [38], we construct trajectory statistical solutions for the Cahn-Hilliard-Navier-Stokes system with moving contact lines.
A new data-driven robust optimization approach to multi-item newsboy problems
Authors: Kou Ying , Wan Zhong
Published: October 2021

A newsboy problem is a typical stochastic inventory management problem and has extensive applications in the fields of operational research, management sciences and marketing sciences. One of the challenges underlying such problems is to handle the uncertainty of demands. In the existing results, it is often to assume that the demand distribution is given to facilitate solution of the problems. In this paper, a novel data-driven robust optimization model for solving multi-item newsboy problems is proposed by combining the absolute robust optimization with a data-driven uncertainty set, and the latter is leveraged to address the uncertainty of demands. For the single-item situation, a closed-form solution is obtained and influences of parameters on the optimal solutions are analyzed. Owing to complexity of the multi-item situation, a uniform smoothing function is leveraged to smooth the proposed model. Then, an algorithm, called a modified Frank-Wolfe feasible direction algorithm, is developed to solve a series of smooth subproblems. Numerical simulation demonstrates that the proposed model in this paper can reduce over-conservation of robust optimization methods and is more robust than other similar well-established methods in the literature. By numerical simulation and sensitivity analysis, it is concluded that: (1) The proposed method can provide more stable optimal order policy and profits than the existing ones; (2) For a product with a higher unit purchase price, the optimal order quantities are more sensitive to its change; (3) In view of profitability, the newsboy should not to be too risk-averse.

This paper studies the pricing and recycling decision problems in a closed-loop supply chain (CLSC) containing a manufacturer, a downstream retailer, and a third-party recycling left. The manufacturer is subjected to the cap-and-trade regulation and determines the wholesale price of products and carbon emission reduction rate. The retailer determines its resale price to meet customer demands. The third-party recycling left determines the collection rate of recycling and remanufacturing used products. The new product demands, total carbon emissions, and recovery of these products are characterized as uncertain variables due to lack of historical data or insufficient data collected for research. By constructing three decentralized game models, we explore the equilibrium solutions under the corresponding decision-making situation and the corresponding analytical solutions. Finally, numerical experiments are performed to show the total profit of supply chain members for each structure and some special insights are drawn.

The localized method of fundamental solutions belongs to the family of meshless collocation methods and now has been successfully tried for many kinds of engineering problems. In the method, the whole computational domain is divided into a set of overlapping local subdomains where the classical method of fundamental solutions and the moving least square method are applied. The method produces sparse and banded stiffness matrix which makes it possible to perform large-scale simulations on a desktop computer. In this paper, we document the first attempt to apply the method for the stress analysis of two-dimensional elastic bi-materials. The multi-domain technique is employed to handle the non-homogeneity of the bi-materials. Along the interface of the bi-material, the displacement continuity and traction equilibrium conditions are applied. Several representative numerical examples are presented and discussed to illustrate the accuracy and efficiency of the present approach.

Let $ \omega $ belong to the weight class $ \mathcal{W} $, the large Fock space $ \mathcal{F}_{\omega}^{p} $ consists of all holomorphic functions $ f $ on $ \mathbb{C}^{n} $ such that the function $ f(\cdot)\omega(\cdot)^{1/2} $ is in $ L^p(\mathbb{C}^{n}, dv) $. In this paper, given a positive Borel measure $ \mu $ on $ {\mathbb C}^n $, we characterize the boundedness and compactness of Toeplitz operator $ T_\mu $ between two large Fock spaces $ F^{p}_\omega $ and $ F^{q}_\omega $ for all possible $ 0 < p, q < \infty $.

Objectives: Previous studies have shown that participation in social activities (SA) can prevent cognitive decline (CD) and that living arrangements (LA) can affect cognitive function. This study aimed to evaluate the effects of SA and LA on CD, as well as their interactions, using longitudinal data.Methods: Data were used from the 2006-2018 Korean Longitudinal Study for Aging, which followed 10 254 adults older than 45 years over a 12-year period. CD was defined as a ≥4-point score decrease in the Mini-Mental Status Exam over 2 years. We developed an extended Cox proportional hazards model for time-dependent covariates to estimate the hazard ratio (HR) of CD in 4 groups: (1) socially active and living with others, (2) socially active and living alone, (3) socially inactive and living with others (SILO), and (4) socially inactive and living alone (SILA). The model was stratified by gender and adjusted for important confounders.Results: The HR of CD was significantly higher in the SILO group in men (HR,1.36; 95% confidence interval [CI], 1.08 to 1.78) and in the SILA group in women (HR, 1.72; 95% CI, 1.08 to 2.75). However, the interaction term for gender was not significant.Conclusions: Among socially inactive elderly adults, the HR of CD was elevated in men who lived with others and in women who lived alone, although the interaction term for gender was not significant. Socially inactive men who live with others and socially inactive women who live alone are particularly encouraged to participate in SA to prevent CD.

Objectives: Pregnant women are especially vulnerable to respiratory infections such as coronavirus disease 2019 (COVID-19), but insufficient research has investigated pregnancy and its outcomes in women with COVID-19. This cross-sectional study compared birth outcomes related to COVID-19 between Bangladeshi pregnant women with and without COVID-19.Methods: The study was conducted at 3 tertiary referral hospitals in Dhaka, Bangladesh, from March to August 2020. Pregnant women admitted for delivery at these hospitals with laboratory results (reverse-transcription polymerase chain reaction) were analyzed. Using convenience sampling, we included 70 COVID-19-positive and 140 COVID-19-negative pregnant women. Trained and experienced midwives conducted the interviews. Data were analyzed using the t-test, the chi-square test, and univariate and multivariable linear and logistic regression.Results: Pregnant women with COVID-19 were more likely to give birth to a preterm baby (adjusted odds ratio [aOR], 2.15; 95% confidence interval [CI], 1.06 to 4.37) and undergo a cesarean section (aOR, 3.27; 95% CI, 1.51 to 7.07). There were no significant differences in birth weight, premature rupture of membranes, and the Apgar score at 1 minute or 5 minutes post-delivery between women with and without COVID-19. All the newborn babies who were born to COVID-19-positive women were COVID-19-negative.Conclusions: Our study suggests that pregnant women with COVID-19 were more likely to give birth to a preterm baby and undergo a cesarean section. For this reason, physicians should be particularly cautious to minimize adverse birth outcomes among pregnant women with COVID-19 and their newborn babies.
