Spontaneous Scalarization in Proto-neutron Stars

Proto-neutron stars are born when a highly evolved and massive star collapses under gravity. In this paper, we investigate the spontaneous scalarization in proto-neutron stars. Based on the scalar tensor theory of gravity as well as the physical conditions in proto-neutron star, we examine the structure of proto-neutron star. To describe the fluid in proto-neutron star, we utilize $SU(2)$ chiral sigma model and the finite temperature extension of the Brueckner-Bethe-Goldstone quantum many-body theory in the Brueckner-Hartree-Fock approximation. Here, we apply the equation of state of proto-neutron stars considering different cases i.e. hot pure neutron matter and hot $\beta$-stable neutron star matter without neutrino trapping as well as with neutrino trapping. The effects of temperature and entropy of proto-neutron stars on the star structure are also studied. Our results confirm that the spontaneous scalarization is affected by different physical conditions in proto-neutron stars.Comment: 16 pages, 9 figures.

Investigating the Effect and Immunity of Tissue Plasminogen Activator in the Treatment of Acute Ischemic Stroke

Background and Objective: Although current evidence has demonstrated the efficacy and immunity of Alteplase, further studies are needed to evaluate its functioning in the therapeutic system. This study aims to assess the effect and immunity of tissue plasminogen activator (tPA) in the treatment of acute ischemic stroke (AIS).Methods: This study was conducted as a retrospective observational study on patients with AIS referred to Ahvaz Golestan Hospital in 2017-2018. By using the hospital database, demographic information, the cause of lack of thrombolytic therapy, the onset of symptoms and admission were extracted. The National Institutes of Health Stroke Scale (NIHSS) at the time of referral, 24 hours after treatment, and at the time of discharge, the modified Rankin Scale (mRS) scores at discharge time and 3 months after discharge, complications and mortality at the time of admission and 3 months after discharge were recorded.Results: The mean of the event to needle (hrs) was significantly lower in the tPA group (P <0.0001), and delay in visiting time and loss of golden time were of the main reasons for not receiving tPA in the control group. The mean difference and the decrease in NIHSS score 24 hours after admission and discharge in the tPA group was significantly higher (P <0.0001). At the time of discharge, the mean score of mRS in the two groups was not significantly different. Three months after treatment, the mean score of mRS in the tPA group was significantly lower than that in the control group (P <0.05). The percentage of patients with bleeding complications was higher in the tPA group (7.27%) than that in the control group (4.89%). The percentage of deaths during the hospital stay in the tPA group (3.64%) was higher than that in the control group (1.63%).Conclusion: Patients with AIS under intravenous thrombolytic therapy with tPA showed improvement in functional measurements and neurological outcomes compared with the control group. Lack of significant difference in the rate of complications and mortality between the two groups indicated the safety and high efficacy of thrombolytic therapy in patients with AIS

Persian Causality Corpus (PerCause) and the Causality Detection Benchmark

Recognizing causal elements and causal relations in the text is among the challenging issues in natural language processing (NLP), specifically in low-resource languages such as Persian. In this research, we prepare a causality human-annotated corpus for the Persian language. This corpus consists of 4446 sentences and 5128 causal relations. Three labels of Cause, Effect, and Causal mark are specified to each relation, if possible. We used this corpus to train a system for detecting causal elements’ boundaries.Also, we present a causality detection benchmark for three machine-learning methods and two deep learning systems based on this corpus. Performance evaluations indicate that our best total result is obtained through the CRF classifier, which provides an F-measure of 0.76. In addition, the best accuracy (91.4) is obtained through the BiLSTM-CRF deep learning metho

A Neuro Symbolic Approach for Contradiction Detection in Persian Text

Detection of semantic contradictory sentences is a challenging and fundamental issue for some NLP applications, such as textual entailments recognition. In this study, contradiction means different types of semantic confrontation, such as negation, antonymy, and numerical. Due to the lack of sufficient data to apply precise machine learning and, specifically, deep learning methods to Persian and other low-resource languages, rule-based approaches are of great interest. Also, recently, the emergence of new methods such as transfer learning has opened up the possibility of deep learning for low-resource languages. This paper introduces a hybrid contradiction detection approach for detecting seven categories of contradictions in Persian texts: Antonymy, negation, numerical, factive, structural, lexical and world knowledge. The proposed method consists of 1) a novel data mining method and 2) a transformer-based deep neural method for contradiction detection . Also, a simple baseline is presented for comparison. The data mining method uses frequent rule mining to extract appropriate contradiction detection rules employing a development set. Extracted rules are tested for different categories of contradictory sentences. In the first step, a classifier checks whether the rules work for an input sentence pair. Then, according to the result, rules are used for three categories of negation, numerical, and antonym. In this part, the highest F-measure is obtained for detecting the negation category (90%), the average F-measure for these three categories is 86%, and for the other four categories, in which the rules have a lower F-measure of 62%, the transformer-based method achieved 76%. The proposed hybrid approach has an overall f-measure of higher than 80%.&nbsp

Comparison of operation room staffs and patients perspectives from “patient privacy” in the operating room

Background and aims: Privacy is one of the fundamental human rights and its consideration during health care is required and caused to maintain dignity and trust between the nurse and patient. This study was performed with the aim of investigateing the privacy of patients in the hospital operating room of Shahrekord University of Medical Sciences from the view of the staff and patients. Methods: This research was a decscriptive-analytic study. 38 operating room personnel and 88 patients who had surgery were selected by census and simple random sampling. Data were collected by a questionaire made by researcher. Data were analyzed using SPSS software with chi-square and t- test. Results: The results showed paying respect to privacy in physical dimention was considered from the standpoints of operating room personnel 62.9, the researcher's observations 60.7 and patients 78.9. Paying respect to privacy has been estimated in social dimension from the view of staff and patients’and the researcher's observation 4, 11, and 5.3, respectively. Paying respect to privacy was considered from informational dimension, from the staff, patients’, and researcher's observations views 54.2 and 79.5, respectively. In total, the results showed there was significant relationship between paying respect to privacy and gender so that more precent of patients stated having no paying respect privacy in physical dimension (P=0.022). Conclusion: Therapy personel and researcher’s observations due to awareness of legal and ethical rules in this regard evaluated paying respect patient’s privacy in the low level. It is obvious to pay more attention personnel and authorities to moral standards in patient care

How much lowering of blood pressure is required to prevent cardiovascular disease in patients with and without previous cardiovascular disease?

Purpose of Review To review the recent large-scale randomised evidence on pharmacologic reduction in blood pressure for the primary and secondary prevention of cardiovascular disease. Recent Findings Based on findings of the meta-analysis of individual participant-level data from 48 randomised clinical trials and involving 344,716 participants with mean age of 65 years, the relative reduction in the risk of developing major cardiovascular events was proportional to the magnitude of achieved reduction in blood pressure. For each 5-mmHg reduction in systolic blood pressure, the risk of developing cardiovascular events fell by 10% (hazard ratio [HR] (95% confidence interval [CI], 0.90 [0.88 to 0.92]). When participants were stratified by their history of cardiovascular disease, the HRs (95% CI) in those with and without previous cardiovascular disease were 0.89 (0.86 to 0.92) and 0.91 (0.89 to 0.94), respectively, with no significant heterogeneity in these effects (adjusted P for interaction = 1.0). When these patient groups were further stratified by their baseline systolic blood pressure in increments of 10 mmHg from  Summary Pharmacologic lowering of blood pressure was effective in preventing major cardiovascular disease events both in people with or without previous cardiovascular disease, which was not modified by their baseline blood pressure level. Treatment effects were shown to be proportional to the intensity of blood pressure reduction, but even modest blood pressure reduction, on average, can lead to meaningful gains in the prevention of incident or recurrent cardiovascular disease

Teaching Reading with a Critical Attitude: Using Critical Discourse Analysis (CDA) to Raise EFL University Students’ Critical Language Awareness (CLA)

This study was planned to investigate the importance of raising students’ critical thinking through explicit teaching of some techniques of critical discourse analysis (CDA). This study aimed to detect any change in the English BA students’ abilities in revealing the hidden layers of meaning implied in the texts. There was an attempt in this study to investigate any change both in students’ views toward learning English language and in their critical language awareness (CLA) before and after teaching critical reading (CR) through CDA techniques. To this end, three paired news articles were provided from different online news sources. Each pair of the first two pairs of news articles dealt with the same subject. Two articles of each pair were selected from two different news sources; online editions of Press TV and BBC. These news sources usually have different perspectives on different issues. The third pair of news reports which had similar subjects was selected from the English newspaper of New York Times. The participants were 60 BA English students studying in University of Kashan. They studied in the fifth and seventh terms. Before teaching CDA techniques, students were asked to analyze these articles critically. After teaching these techniques, they analyzed the same texts for the second time. Then they responded to a questionnaire to reveal any change in their attitudes toward English language learning or any increase in their motivation to learn it. After the examination of students’ analyses and the investigation of their answers given to the questionnaire, it was revealed that CLA of about 90٪ of students increased. Their motivation also increased in learning English language after becoming familiar with the field of CDA

Effect of audio-visual education on self-efficacy toward marriage in single people with type 1 diabetes

People with diabetes report that diabetes affects particular aspects of their marital life and leads to other problems in their lives. Moreover, the self-efficacy of diabetic patients is affected by their disease in various respects. There is a significant relationship between self-efficacy and health behaviors. Objectives: This study was conducted to determine the effect of audio-visual education on self-efficacy toward marriage in single people with type 1 diabetes. Methods: This randomized, controlled trial study was carried out on 100 unmarried patients with type 1 diabetes visiting Iran’s diabetes society in 2015 - 2016. The convenient sampling method was used in this study. Samples were divided into two groups (50 patients in each group) with a simple, randomized sampling method. The data collecting tool was a researcher-made questionnaire that patients completed before the intervention and eight weeks afterwards. The intervention was an educational CD about improving self-efficacy toward marriage in diabetics. Using descriptive statistics, inferential statistics (i.e., chi-square, t-test, paired t, Fisher, and co-variance tests), and SPSS software version 16, the self-efficacy toward marriage in both the intervention and control groups was compared. A significant level was considered less than 0.05. Results: The mean of the self-efficacy score improved significantly in the intervention group (84.14 ± 16.29 to 105.82 ± 5.49, P < 0.001). However, this score decreased in the control group (92.92 ± 12.33 to 86.48 ± 11.54, P < 0.001). In addition, the self-efficacy in the control group was higher than in the intervention group before the study (P = 0.003), although the score of the intervention group significantly increased after the study (P < 0.001). Conclusions: This study showed that audio-visual training can have a significant effect on the self-efficacy of people with type 1 diabetes. Providing audio-visual equipment to referral centers of type 1 diabetics, such as hospitals, health centers, and clinics, as well as informing related officials, can be of benefit to managers
