Investigation of commuting Hamiltonian in quantum Markov network

Graphical Models have various applications in science and engineering which include physics, bioinformatics, telecommunication and etc. Usage of graphical models needs complex computations in order to evaluation of marginal functions,so there are some powerful methods including mean field approximation, belief propagation algorithm and etc. Quantum graphical models have been recently developed in context of quantum information and computation, and quantum statistical physics, which is possible by generalization of classical probability theory to quantum theory. The main goal of this paper is preparing a primary generalization of Markov network, as a type of graphical models, to quantum case and applying in quantum statistical physics.We have investigated the Markov network and the role of commuting Hamiltonian terms in conditional independence with simple examples of quantum statistical physics.Comment: 11 pages, 8 figure

Education’s effect on the empowerment of volunteers about couples communication skills in East Tehran’s Health Center

Background and Aims: Communication and relationship skills in people’s lives, especially in the context of marriage are important as the other aspects of the marriage are over. Previous studies have shown that couples improve communication skills, increase intimacy in their marriage and will reduce conflicts. The main objective of this program is to use an active education system to upgrade the knowledge and strengthenskills of health Volunteers. This study aimed to determine the effect of education on couples’ communication skills ability in East Tehran Health Center volunteers.Materials and Methods: This research is a quasi-experimental study in which 112 people from the health care facility in East Tehran Center were selected randomly and studied as a sample in two different test and control groups. At the first meeting the questionnaires were distributed and completed between both groups. The results were analyzed based on experimental programs using methods including role playing,and group discussion for 4-weeks training. A month after the questionnaires were completed and returned byboth groups the results were analyzed using descriptive and experimental methods including Wilcoxon and Mann-Whitney tests at a significance level (p <0.05).Results: Statistical analysis showed a significant difference in the mean scores of empowerment before and after in group. Also significant differences were found in empowerment scores in the area of cognitive distortions, listening, anger management and problem solving(p<0.001) and the problem solving skillsshowed the greatest increase. Conclusion: Holding communication skills trainings would have potential impacts on health and is desirable, therefore, it is recommended to perform educational programs to empower volunteers’ ability.Key words: Education, Empowerment, Health volunteers, Couples’ communication skill

Accrual-based accounting system versus cash-based accounting: An empirical study in municipality organization

There are many cases, where we may wish to choose a good accounting system and would like to learn how they work and the advantages and disadvantages of each so we can choose the better one for a business. In this paper, we present an empirical survey to understand whether we can choose accrual or cash accounting system. The proposed study designs a questionnaire among 220 experts in area of accounting affairs. The survey considers four sub hypotheses and one main hypothesis to see whether there are reliable rules and regulations in accrual-based accounting compared with cash accounting or not. Similarly, the survey investigates whether accrual-based accounting is more informative, comprehensive and provides better comparative results compared with cash accounting. The results indicate that accrual-based account performs better in terms of all mentioned criteria and it is a better method for managing accounting affairs compared with cash accounting systems

In vivo identification of novel TGIF2LX target genes in colorectal adenocarcinoma using the cDNA-AFLP method

Background and study aims: Homeobox-containing genes are composed of a group of regulatory genes encoding transcription factors involved in the control of developmental processes. The homeodomain proteins could activate or repress the expression of downstream target genes. This study was conducted to in vivo identify the potential target gene(s) of TGIF2LX in colorectal adenocarcinoma. Methods: A human colorectal adenocarcinoma cell line, SW48, was transfected with the recombinant pEGFPN1-TGIF2LX. The cells were injected subcutaneously into the flank of the three groups of 6-week-old female athymic C56BL/6 nude mice (n = 6 per group). The transcript profiles in the developed tumours were investigated using the cDNA amplified fragment length polymorphism (cDNA-AFLP) technique. Results: The real-time RT-PCR and DNA sequencing data for the identified genes indicated that the N-terminal domain-interacting receptor 1 (Nir1) gene was suppressed whereas Nir2 and fragile histidine triad (FHIT) genes were upregulated followed by the overexpression of TGIF2LX gene. Conclusion: Downregulation of Nir1 and upregulation of Nir2 and FHIT genes due to the overexpression of TGIF2LX suggests that the gene plays an important role as a suppressor in colorectal adenocarcinoma. � 2018 Pan-Arab Association of Gastroenterology.

Platelet kinetics after slow versus standard transfusions: A pilot study

Background. Platelet transfusion is required in the acute phase of some thrombocytopenic disorders in order to prevent potentially dangerous hemorrhages. The purpose of this study was to assess the increase in platelet count following a slow platelet transfusion. Methods. Patients suffering from thrombocytopenia due to various underlying diseases were enrolled in the prospective pilot feasibility trial and were randomly divided into two groups. Standard platelet transfusion was administered in one group, while slow transfusion was used in the other. The platelet count was examined at 1 hour, 24 hours, and 1 week following the transfusions. Results. Although the platelet count was higher following 1 hour after transfusion via the standard method, the count tended to be higher 1 week after the transfusion in the slow transfusion group. This difference, however, only turned out to be statistically significant amongst females. Conclusion. A therapy of slow platelet transfusion might be more effective for the prevention of platelet loss. Further studies will be required to strengthen this hypothesis

Targeting host calcium channels and viroporins: a promising strategy for SARS-CoV-2 therapy

Despite passing the pandemic phase of the COVID-19, researchers are still investigating various drugs. Previous evidence suggests that blocking the calcium channels may be a suitable treatment option. Ca2+ is required to enhance the fusion process of SARS-CoV-2. Also, some important inflammatory factors during SARS-CoV-2 infection are dependent on Ca2+ level. On the other hand, viroporins have emerged as attractive targets for antiviral therapy due to their essential role in viral replication and pathogenesis. By inhibiting the host calcium channels and viroporins, it is possible to limit the spread of infection. Therefore, calcium channel blockers (CCBs) and drugs targeting viroporins can be considered an effective option in the fight against SARS-CoV-2
