Safety-critical Policy Iteration Algorithm for Control under Model Uncertainty

Safety is an important aim in designing safe-critical systems. To design such systems, many policy iterative algorithms are introduced to find safe optimal controllers. Due to the fact that in most practical systems, finding accurate information from the system is rather impossible, a new online training method is presented in this paper to perform an iterative reinforcement learning based algorithm using real data instead of identifying system dynamics. Also, in this paper the impact of model uncertainty is examined on control Lyapunov functions (CLF) and control barrier functions (CBF) dynamic limitations. The Sum of Square program is used to iteratively find an optimal safe control solution. The simulation results which are applied on a quarter car model show the efficiency of the proposed method in the fields of optimality and robustness

Evaluation of bone density and its relation with radiographic stage in knee osteoarthritis, 2016-2017

Background: Osteoarthritis (OA) is the most common arthritis and its incidence is directly related to age. According to the related research in the last 30 years, a relationship is reported between severity of osteoarthritis and bone density. The aim of this study was to investigate the bone density and its relation with radiographic stage in knee OA.Methods: In this descriptive cross-sectional study, 123 patients with knee OA diagnosis who referred to rheumatology clinic at Imam Khomeini hospital in Ardabil, were selected to participate in our study. Age, sex, weight, height and other variables were collected and analyzed with SPSS version 21.Results: A significant correlation was found between T-score and age of the patients (r=-0.38, p=0.001). A significant correlation was found between T-score and BMI. The correlation of T-score and radiographic stage of patients with osteoarthritis was indirect and non-significant (r=-0.22, p=0.06). Multivariate regression models showed that among variables, only two variables BMI and age had significant relation with T-score.Conclusions: Results showed that the relation between radiographic stage and T-score was significant and BMI and age had a significant effect on T- score

Predicting microRNAs as Anti-viral Agents in SARS-CoV-2 Infection Based on the Bioinformatics Approach: A Systematic Review

Purpose: The beginning of 2020, the World health organization (WHO) declared severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as responsible for the coronavirus disease 2019 (COVID-19) outbreak. Previous studies showed that microRNAs (miRNAs) are able to inhibit pathogenesis of DNA or RNA viruses by binding the genome. The purpose of the current study is an overview of the anti-viral role of cellular miRNAs against the COVID-19 infection. Methods: Our search was limited to all published original papers in the English language from 2019 to 2021 using several databases including PubMed, Google scholar, Scopus, and Science Direct. A manual search of references for included articled was also performed. Among 66 electronically searched citations, 17 papers met the inclusion criteria. Results: The presence of miRNAs during the COVID-19 infection, reported by several studies, predicts the possibility of using miRNAs as potential tools to eradicate the SARS-CoV-2 infection. In some studies, miRNAs have presented as a tool for targeting SARS-CoV-2 encoded genes which are essential in viral biogenesis, entrance, replication, and infection. Conclusion: The comparison of miRNA between SARS-CoV-2 with other human coronaviruses will help the better understanding of distinct clinical characteristics of them

Acute Myocardial Infarction Due to Dissection of the Coronary Arteries Associated with Premature Atherosclerosis in Late Postpartum: A Case Report of Maternal Death

AbstractIntroduction: Atherosclerotic coronary artery disease is the most common form of heart disease that is associated with high rates of acute myocardial infarction (AMI) and death in young people.Methods: Given the importance of pregnancy and the postpartum period and the fact that AMI is associated with poor maternal outcomes in postpartum, the present study reports acute myocardial infarction due to dissection of the coronary arteries associated with premature atherosclerosis in late postpartum.Results: The case was the maternal death of a 34-year-old woman at 42 days postpartum without any history of underlying diseases or symptoms, whose autopsy report read AMI due to coronary artery dissection associated with atherosclerosis.Conclusions: This report emphasizes the importance of postpartum care and attention to any symptoms witnessed during this period

The role of adverse childhood experiences and attachment style in predicting pain perception in women with breast cancer; the mediating role of perceived social support

Introduction: Breast cancer is the most common malignancy among diseases which is the leading cause of death in women with more than two million deaths per year. Pain in cancer patients has a complex relationship with adverse childhood experiences, attachment and social support, the multiple relationships of which has not been studied to date. The present study was conducted aimed to investigate the multiple dimensions of this relationship. Methods: In a cross-sectional study in the form of a structural equation modeling, during the period from July to September 2021, 360 participants diagnosed with breast cancer who referred to three chemotherapy centers in Tehran were selected using purposeful sampling method and entered into the study process after obtaining informed consent and fulfilling the assumed criteria. Four indicators of adverse childhood experiences, attachment style, pain, and perceived social support were completed by participants over a period of time. Data were analyzed using SPSS and Amos software version 25. Results: Data analysis showed that adverse childhood experiences mediated by perceived social support was associated with the perception of pain in women with breast cancer (P<0.05). But the relationship between avoidant (β = 0.015), safe (β = -0.023) and ambivalent (β = 0.026) attachment styles with pain perception was not significant and attachment styles through perceived social support could not have a significant effect on pain perception (P >0.05). Conclusion: some parts of the findings of this study, in line with the research background, indicate the relationship between adverse childhood experiences and pain perception and highlight the role of perceived social support. However, the relationship between attachment styles and pain perception is a complex one that requires further study

Determination of flood extend using OLI data (case study: Dezful 2016 flood)

Among the various natural hazards, floods may be considered as the most devastating factor that inflicts great damage on human societies. Therefore, the importance of estimating flood damage and its scope in planning to reduce damages and determine points with high risk is very important. The aim of this study is to determine the extent of flood hazard using OLI satellite data. For this reason, a window of OLI satellite images of Landsat 8 was acquired before and after the Dezful flood of April 25, 2016. First, preprocessing operations include radiometric and atmospheric corrections of images were done, and the principal component analysis was then used to reduce the correlation of the data. Data processing was performed using a Support Vector Machine algorithm with linear and polynomial kernels. In order to train the Support Vector Machine algorithm, training samples for each class (agricultural land, flood extent, water resources, settlement areas, and recreational areas along the river boundary) were harvested at the user level. In order to evaluate the similarity of the classes and the degree of correlation between the samples, the quantitative assessment method of the Jeffries Matusita was performed. The results showed that the flood area was 11593.26 ha, the highest damage was due to agricultural land with a destruction of 8467.45 ha and recreational and tourist areas along the riverbank with a destruction of 2659.14 ha
