ISLAMIC REPUBLIC OF IRAN TOWARDS CENTRAL AND EASTERN EUROPE UPON THE BACKGROUND OF THE WAR IN UKRAINE
The article attempts to analyze the politics of the Islamic Republic of Iran towards the Central and Eastern Europe during the war conflict in Ukraine, 2022. The aim of the study is to describe the tactic and strategic approach of the IRI to the abovementioned problem in order to answer the question about the power shift in Central Asia. An additional aim is to show the image of the USA and NATO as created by the IRI, and to point to the role of Poland in the IRI’s tactical actions to sustain positive relations with Europe. The role of Russia, one of the most influential actors both in the European and in the Eurasian areas cannot be omitted.
The Katyń Forest Massacre
Authors: Beshenich Caroline 
Published: April 2024

This article explores the relationship between political expediency, perception management, and governmental goals. The subject matter forms the research question of “How a tool such as perception management can be used to politically expedite a government’s interests and goals?” It is understood that these ends can be achieved through the usage of perception management by constructing them from a given audience’s interests and values. The concept of perception management is introduced to the reader and illustrated by the example of the United States government’s knowledge of the Katyń Forest Massacre. This article is presented in two parts – the United States’ initial conclusion that the Nazi party was responsible for the massacre and its later reassignment of fault to the Soviet Union. The first instance which involved the reconstruction of truth, was used to politically advance the United States’ cooperation with the Soviet Union in fighting Hitler’s Germany. The second instance also involved the revelation of truth and was used to justify its fight against the North Korean communists. This article should effectively demonstrate how the practice of perception management has been used historically by the United States government to expediate its political goals. The instrumentalization of Katyń is important as it may inspire the reader to consider why certain events take hold of the media’s attention versus others, and how these events specifically may relate to domestic and international political issues.
Optimal Contracts for Time-Inconsistent Consumers with Heterogeneous Beliefs
Authors: Gao Buqu , Guo Liang 
Published: April 2024

In many markets (e.g., cell phones, video games), firms offer menus of contracts that include some tariffs charging per-use prices above marginal cost and others below marginal cost. We term this puzzling phenomenon as two-sided deviations from marginal cost pricing and present a potential explanation based on two well-recognized consumer characteristics. The first one is that consumers’ actual consumptions may depart systematically from their initial plans (i.e., time-inconsistent preferences). In addition, consumers can be either sophisticated or naive in their beliefs about their time inconsistency (i.e., heterogenous beliefs). We characterize properties of the optimal contracts for a firm to screen the time-inconsistent consumers with heterogeneous beliefs. We articulate the conditions under which the optimal menu may account for two-sided deviations from marginal cost pricing. We also show that, contrary to intuition, a higher degree of time inconsistency may reduce firm profit and increase social welfare. Meanwhile, reducing consumer naivete may harm the society. Moreover, we confirm that our main results are robust to the presence of time-consistent consumers. This paper was accepted by Dmitri Kuksov, marketing.

A service evaluation of a new regional integrated stroke service in the NHS
Authors: Buckley Amy 
Published: April 2024

Background: Stroke is the UK's leading cause of disability and contributes to numerous deaths. In response, centralised stroke care is on the rise, both globally and in the UK. A local trust has formed a regional stroke centre to provide efficient and timely emergency treatment. Aims: This article evaluates hyperacute performance in a new service, identifying areas for improvement and monitoring standards. It also aims to address and minimise shortfalls in preparation for the upcoming opening of a designated stroke hub, which will admit patients directly to the stroke team, bypassing the emergency department. Methods: Data were extracted from the Sentential Stroke National Audit Programme (SSNAP) database from 26 September 2022 to 26 January 2023. Comparison was made to national quarterly SSNAP data from October 2022 to December 2022, due to the corresponding publication dates. Literature was sourced from the Cumulative Index to Nursing & Allied Health database. The main targets within SSNAP based on the first 4 hours of patient care were identified and analysed. Findings: From admission, 64% of patients underwent computer tomography scanning under 1 hour from admission, compared to a national average of 56.6%; 76% of patients underwent a swallow screening under 4 hours from admission, compared to a national average of 71.5%; and 37% of patients achieved admission to the hyperacute stroke unit under 4 hours from admission, compared to a national average of 39.5%. National average data were taken directly from SSNAP national averages from the report spanning October 2022 to December 2022. Conclusion: In comparison to national averages in many areas, the current service is performing well; however, there are many areas for improvement to address. Although the outlook for stroke care looks more promising as newer technologies emerge, stroke prevalence is increasing simultaneously. Stroke continues to cost the UK upwards of 26 billion pounds per year and causes significant detriment to survivors. Therefore, healthcare has a duty of care to continue to improve standards and innovate to improve outcomes.

Published: April 2024

Abstract
Measurement invariance (MI) is a psychometric property of an instrument indicating the degree to which scores from an instrument are comparable across groups. In recent years, there has been a marked uptick in publications using MI in intellectual and developmental disability (IDD) samples. Our goal here is to provide an overview of why MI is important to IDD researchers and to describe some challenges to evaluating it, with an eye towards nudging our subfield into a more thoughtful and measured interpretation of studies using MI.
Reduction in time to viral suppression among persons living with HIV in Jamaica between 2017–2019
Authors: Cushnie Anya , Reintjes Ralf , Artama Miia , Figueroa J. Peter 
Published: April 2024

Introduction
HIV viral suppression is important for effective treatment and for reducing new infections. In 2019, only 66% of persons on antiretroviral treatment (ART) in Jamaica were virally suppressed. We aim to compare time to viral suppression by ART initiation year and type of treatment site to understand the implications for programming.

Methods
We assessed time to viral suppression among 4560 persons who received viral load testing either pre or post ART initiation from 2017–2019. We used descriptive statistics and Kaplan-Meier estimates to compare survival curves by ART year (2017, 2018, 2019), sex and type of treatment site (public and non-governmental organizations). Persons were censored if suppression was not achieved. Mixed effects Cox regression was used to determine the effect of covariates on the likelihood of viral suppression. We report hazard ratios and 95% confidence intervals.

Results
Pre-ART viral load testing decreased from 36% in 2017 to 30% in 2019. For post-ART viral load tests, approximately 78% (n = 1589) of persons achieved suppression, 51% (n = 809) were female and 86% (n = 1341) used a public treatment site. The median time to suppression decreased by 3 months from 2017 to 2019. The likelihood of suppression was almost 2 times greater in 2018 (HR = 1.56, CI = 1.39–1.75) and 3 times greater in 2019 (HR = 3.17, CI = 2.76–3.64) compared to 2017. NGO treatment sites were also significantly associated with the likelihood of viral suppression compared to public sites.

Conclusion
Pre-ART viral load testing and the time to viral suppression decreased over three years. Initiating ART after 2017 and early use of NGO treatment sites were found to significantly increase the likelihood of achieving suppression. This demonstrates improvements in the national HIV response but there is need to increase the number of persons on ART and achieving viral suppression.
Prevalence and predictors of prenatal depression during the COVID-19 pandemic: A multistage observational study in Beijing, China
Authors: WANG Jin , HU Libin , ZHANG Tianyi , LIU Jiajia , YU Chuan , ZHAO Ningxin , QI Jianlin , LIU Lihua 
Published: April 2024

Objective
While growing psychological health issues among pregnant women during the COVID-19 pandemic have been clearly validated, most research was conducted in countries with relatively lax quarantine measures. This study aimed to compare the prevalence of prenatal depression among pre-, peak-, and post-COVID-19 in Beijing, the region with a stringent response policy in China. We also explore predictors of prenatal depression throughout the outbreak.

Methods
We investigated prenatal depression among 742 pregnant women who received antenatal checkups in Beijing from March 28, 2019 to May 07, 2021 using the Edinburgh Postnatal Depression Scale and associative demographic, pregnancy-related, and psychosocial characteristics were measured. The phase was divided into pre-, peak-, and post-COVID-19 in light of the trajectory of COVID-19. Pearson’s Chi-square test was used after the examination of confounders homogeneity. The bivariable and multivariable logistic regression was conducted to explore predictors.

Results
The pooled prevalence of prenatal depression was 11.9% throughout the COVID-19 pandemic. Rates at different phases were 10.6%, 15.2%, and 11.1% respectively and no significant difference was observed. Multivariable logistic regression revealed that history of mental illness, number of boy-preference from both pregnant women and husband’s family, social support, occupation, and living space were independent predictors of prenatal depression in Beijing.

Conclusion
Our data suggested that the impact of this pandemic on prenatal depression in Beijing appears to be not significant, which will strengthen confidence in adhering to current policy for decision-makers and provide important guidance for the development of major outbreak control and management policies in the future. Our findings may also provide a more efficient measure to identify high-risk pregnant women for professionals and help raise gender equity awareness of pregnant women and their husbands’ families. Future studies should focus on the value of targeted care and family relations on the mental health of pregnant women.
Systemic immune-inflammatory indicators and bone mineral density in chronic kidney disease patients: A cross-sectional research from NHANES 2011 to 2018
Authors: Jiang Yuying , Bao Xiaorong 
Published: April 2024

Background
The purpose of this study was to look at the relationship between the Systemic Immune Inflammatory Index (SII) and bone mineral density (BMD) in the pelvis, left upper and lower limbs, lumbar spine, thoracic spine, and trunk in a chronic kidney disease (CKD) population in the United States.

Methods
The National Health and Nutrition Examination Survey (2011–2016) yielded 2302 people with CKD aged >18 years. CKD was defined as eGFR less than 90 ml/min/1.73 m2 or eGFR greater than 90 ml/min/1.73 m2 with urine ACR greater than 30 mg/L.SII was calculated as PC * (NC / LC) from platelet count (PC), neutrophil count (NC), and lymphocyte count (LC). Multiple logistic regression was used to examine the relationship between BMD and SII at different sites in CKD patients, smoothed curve-fitting and generalized weighting models were used to investigate non-linear relationships, and a two-tailed linear regression model was used to find potential inflection points in the model.

Results
We discovered a negative correlation between SII and pelvic BMD among 2302 participants after controlling for gender, age, and race [β = -0.008; 95% confidence value -0.008; 95% confidence interval (CI) -0.014, -0.002]. Lower PEBMD was related to increasing SII (trend p = 0.01125). After additional correction, only pelvic BMD remained adversely linked with SII [value -0.006; 95% CI -0.012, -0.000, p = 0.03368]. Smoothed curve fitting revealed a consistent inverse relationship between SII and pelvic BMD. Further stratified analyses revealed a substantial positive negative connection between SII and pelvic BMD in individuals who did not have hypertension, diabetes, a BMI of more than 30 kg/m2, or stage 2 CKD. The connection between SII and PEBMD in people without diabetes revealed a strong inverted U-shaped curve.

Conclusion
In individuals with CKD in the United States, there was a negative connection between the systemic immunoinflammatory index (SII) and pelvic BMD. The SII might be a low-cost and simple test for CKD-related BMD loss.

INTRODUCTION:
Diabetes (T3cDM) secondary to chronic pancreatitis (CP) arises due to endocrine dysfunction and metabolic dysregulations. Currently, diagnostic tests are not available to identify patients who may progress from normoglycemia to hyperglycemia in CP. We conducted plasma metabolomic profiling to diagnose glycemic alterations early in the course of disease.

METHODS:
Liquid chromatography-tandem mass spectrometry was used to generate untargeted, targeted plasma metabolomic profiles in patients with CP, controls (n = 445) following TRIPOD guidelines. Patients were stratified based on glucose tolerance tests following ADA guidelines. Multivariate analysis was performed using partial least squares discriminant analysis to assess discriminatory ability of metabolites among stratified groups. COMBIROC and logistic regression were used to derive biomarker signatures. AI-ML tool (Rapidminer) was used to verify these preliminary results.

RESULTS:
Ceramide, lysophosphatidylethanolamine, phosphatidylcholine, lysophosphatidic acid (LPA), phosphatidylethanolamine, carnitine, and lysophosphatidylcholine discriminated T3cDM CP patients from healthy controls with AUC 93% (95% CI 0.81–0.98, P < 0.0001), and integration with pancreatic morphology improved AUC to 100% (95% CI 0.93–1.00, P < 0.0001). LPA, phosphatidylinositol, and ceramide discriminated nondiabetic CP with glycemic alterations (pre-diabetic CP); AUC 66% (95% CI 0.55–0.76, P = 0.1), and integration enhanced AUC to 74% (95% CI 0.55–0.88, P = 0.86). T3cDM was distinguished from prediabetic by LPA, phosphatidylinositol, and sphinganine (AUC 70%; 95% CI 0.54–0.83, P = 0.08), and integration improved AUC to 83% (95% CI 0.68–0.93, P = 0.05). CombiROC cutoff identified 75% and 78% prediabetes in validation 1 and 2 cohorts. Random forest algorithm assessed performance of integrated panel demonstrating AUC of 72% in predicting glycemic alterations.

DISCUSSION:
We report for the first time that a panel of metabolites integrated with pancreatic morphology detects glycemia progression before HbA1c in patients with CP.
Shale hydraulic fracture morphology and inter-well interference rule under multi-wellbore test
Authors: Ma Yulin , Du Yupeng , Lu Dandan 
Published: April 2024

Abstract
This study conducted a series of true triaxial hydraulic fracturing experiments on Longmaxi Formation shale. We investigated the interaction between internal factors and external factors on the inter-well interference of 400 mm cubic porous specimens. During dual wellbore fracturing at different formations, forming inter-well interference through secondary hydraulic fractures lead to a lower interference intensity and larger stimulated rock area. When adopting a three-layer well layout during three-wellbore fracturing, the vertical distance between the wells is shortened, activating more bedding planes. Regardless of a horizontal well placement with two wellbores or a three-dimensional two-layer well placement with three wellbores, increasing the vertical stress leads to more potent inter-well interference. There is no absolute positive correlation between the stimulated rock area and inter-well interference. It can be influenced by the presence of natural fractures within the formation that can even lead to a reduction in the stimulated area. When the well placement changes from two horizontal wellbores to three-dimensional two-layer sites with three wellbores and the vertical stress increases, the inter-well interference becomes stronger, but the stimulated rock area only increases by 22.6%. These findings provide crucial guidance for the hydraulic fracturing design of shale reservoirs.
Effect of recrystallization degree on properties of passive film of super ferritic stainless steel S44660

Published: April 2024

Abstract
The effect of the recrystallization degree on the properties of passive films formed in 0.1 M HNO3 solution for super ferritic stainless steel S44660 was examined in this study. The initial specimens, in their cold-rolled state, showed a high dislocation density, as observed through electron backscatter diffraction (EBSD) experiments. Analysis of potentiodynamic polarization (PDP) curves and electrochemical impedance spectroscopy (EIS) measurements suggested that with the increase of recrystallization degree, the corrosion current density reduced and the corrosion potential increased. As revealed by Mott–Schottky analysis, the passive film showed a dual structure of n-type and p-type semiconductors, with the carrier density of the passive film decreasing as the recrystallization degree increased. X-ray photoelectron spectroscopy (XPS) provided insights into the film composition, indicating that the Fe2O3 and Cr2O3 content, which improved the stability of the passive film, increased with the degree of recrystallization. In summary, the increase in recrystallization degree reduced the number of defects in the microstructure, thereby creating favorable conditions for the formation of highly protective passive films. The passive film formed after complete recrystallization exhibited enhanced corrosion resistance.

Analysis of 1-year energy data of a 5 kW and a 122 kW rooftop photovoltaic installation in Dhaka
Authors: Hossion Mohammad Abul 
Published: April 2024

Abstract
Since 2010, rooftop photovoltaic (PV) systems have been extensively used in Bangladesh. This PV system contributes 2–3% to the country's energy demand. In recent years (2020–2024), at least ten large-scale 20–100 MW PV power plants are coming into operation. However, the growth rate of the new PV system is limited by a few factors, such as sustainable energy output over a long time, financial return on investment, and reliability of the energy. To maintain a steady growth of the electrical energy produced from the PV system, research on the performance of the older installations is required. This study analyzes the various data (generated dc power from sunlight, transmitted ac power to the grid) of a 5 kW (March 2021–February 2022) and a 122.4 kW (January 2022–December 2022) rooftop grid-connected solar installation for 12 months. The polycrystalline silicon PV systems are 8 and 4 years old, respectively. The yearly average performance ratio of the 5 and 122.4 kW systems is 17% and 79%, respectively. The results of the study will encourage the investors and community to achieve a 10% share in the national energy demand in the context of Bangladesh.
