H-GA-PSO Method for Tuning of a PID Controller for a Buck-Boost Converter Modeled with a New Method of Signal Flow Graph Technique

In this paper, a new method of signal flow graph technique and Mason’s gain formula are applied for extracting the model and transfer functions from control to output and from input to output of a buck-boost converter. In order to investigate necessity of a controller for the converter with assumed parameters, the frequency and time domain analysis is done and the open loop system characteristics are verified. In addition, the needed closed loop controlled system specifications are determined. Moreover, designing a controller for the mentioned converter system based on the extracted model is discussed. For this purpose, a proportional-integral-derivative (PID) controller is designed and the hybrid of genetic algorithm (GA) and particle swarm optimization (PSO), called H-GA-PSO method is used for tuning of the PID controller. Finally, the simulation results are used to show the performance of the proposed modeling and regulation methods

Simethicone for the Preparation before Esophagogastroduodenoscopy

Aim. The presence of air bubbles and foam in stomach and duodenum is a common problem during esophagogastroduodenoscopy (EGD). Methods. Candidates of elective EGD received 40 mg chewable tablet of simethicone (n = 90) or placebo (n = 83), with 30 mL water, 15–30 min before the EGD. Foam/air bubbles during endoscopy were assessed and graded on a 4-point scale, and patients' satisfaction with the endoscopy was scored from 0 to 10. Results. The amount of gastric but not duodenal foam/air bubbles was significantly lower in the simethicone group compared with the placebo group (P = 0.002). Duration of endoscopy was, on average, one minute shorter in the simethicone group compared with the placebo group (P < 0.001). Patients' satisfaction with the procedure was the same in the two groups. Conclusion. Administration of simethicone prior to EGD reduces the amount of gastric foam and bubbles and provides better visibility for evaluating the mucosa. It also decreases the duration of endoscopy. Further trials are required to find the final effect of the drug on diagnosis of pathological lesions

The Effect of Non-nutritive Sucking on Mother's Finger on Feeding Tolerance and Attainment of Independent Oral Feeding in Preterm Infants: A Randomized Trial

Background Non-nutritive sucking is part of the initial development process in preterm infants that may speed up the transition from the tube to oral feeding. The aim of this study was to evaluate the effect of non-nutritive sucking on mother's finger on feeding tolerance and attainment of independent oral feeding in preterm infants. Materials and Methods This single blind clinical trial was conducted on 40 preterm infants admitted to the NICU of Imam Reza Hospital, Kermanshah in 2017. In the intervention group, non-nutritive sucking was performed on the mother's finger three times a day for 10 days during the first 10 minutes of gavage. Then, the gastric residual volume, time to achieve independent oral feeding, length of hospitalization, and weight at discharge were measured. The data was analyzed using SPSS software version 24.0. Results: According to the results, the mean of gastric residual volume was less in the intervention group (0.65±0.33) compared to the control group (2.30±0.71) (

The effectiveness of short-term dynamic/interpersonal group therapy on perfectionism; assessment of anxiety, depression and interpersonal problems

Introduction: Perfectionism is acknowledged as a core vulnerability and a perpetuating factor in several psychopathologies. The purpose of the present study was to investigate the effectiveness of short-term dynamic/interpersonal group therapy on perfectionism and perfectionism-related distress such as anxiety, depression, and interpersonal problems. Method: This study is a quasi-experimental study applying clinical trial method and contains pre-test, post-test, follow-up periods and control group. The study population included students and the sample consisted of 30 people with extreme perfectionism, who were assigned in two groups of 15 people, experimental and waiting list groups using randomized block design. Research instruments included TMPS, PSPS, PCI, BDI-II, BAI and IIP-32 scales. In order to analyze the collected data, mixed analysis of variance and Repeated Measures Analysis of Variance were used in SPSS software version 22. Findings: The results show that the intervention in the experimental group compared to the waiting list group caused a clinically and statistically significant decrease in the mean scores. This result is observable and evident in all levels of perfectionism and psychological distress (anxiety, depression and interpersonal problems), except for the subscale of non-display of imperfection from the PSPS scale. These results were preserved through the follow-up periods. Discussion: These results show that short-term dynamic/interpersonal group therapy is effective in treating most of the components of perfectionism, and concerning its effectiveness; it reduced psychological distress and showed that the components pertaining to perfectionism are factors of vulnerability in this regard.

Conjugation of R-Phycoerythrin to a Polyclonal Antibody and F (ab&apos;)2 Fragment of a Polyclonal Antibody by Two Different Methods

Abstract R-Phycoerythrin (R-PE), a fluorescent protein from phycobiliprotein family, is isolated from red algae. Conjugation of antibodies to R-PE facilitates multiple fluorescent staining methods. In the present study polyclonal antibodies and polyclonal F(ab&apos;)2 fragment antibodies were conjugated to R-PE by two different methods. The efficiency of the methods was evaluated using Immunocytochemistry (ICC) and Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE). In the first conjugation method, PE was attached to SMCC linker followed by conjugation of antibody to PE-SMCC. In the second method, SH groups were added onto R-PE molecule, while the antibody was attached to SPDP linker. Then, the antibody-SPDP molecule was conjugated to R-PE. Our results showed that the two conjugation methods did not have any abrogative effects on the antibody binding activity

Global, regional, and national burden of disorders affecting the nervous system, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

BackgroundDisorders affecting the nervous system are diverse and include neurodevelopmental disorders, late-life neurodegeneration, and newly emergent conditions, such as cognitive impairment following COVID-19. Previous publications from the Global Burden of Disease, Injuries, and Risk Factor Study estimated the burden of 15 neurological conditions in 2015 and 2016, but these analyses did not include neurodevelopmental disorders, as defined by the International Classification of Diseases (ICD)-11, or a subset of cases of congenital, neonatal, and infectious conditions that cause neurological damage. Here, we estimate nervous system health loss caused by 37 unique conditions and their associated risk factors globally, regionally, and nationally from 1990 to 2021.MethodsWe estimated mortality, prevalence, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs), with corresponding 95% uncertainty intervals (UIs), by age and sex in 204 countries and territories, from 1990 to 2021. We included morbidity and deaths due to neurological conditions, for which health loss is directly due to damage to the CNS or peripheral nervous system. We also isolated neurological health loss from conditions for which nervous system morbidity is a consequence, but not the primary feature, including a subset of congenital conditions (ie, chromosomal anomalies and congenital birth defects), neonatal conditions (ie, jaundice, preterm birth, and sepsis), infectious diseases (ie, COVID-19, cystic echinococcosis, malaria, syphilis, and Zika virus disease), and diabetic neuropathy. By conducting a sequela-level analysis of the health outcomes for these conditions, only cases where nervous system damage occurred were included, and YLDs were recalculated to isolate the non-fatal burden directly attributable to nervous system health loss. A comorbidity correction was used to calculate total prevalence of all conditions that affect the nervous system combined.FindingsGlobally, the 37 conditions affecting the nervous system were collectively ranked as the leading group cause of DALYs in 2021 (443 million, 95% UI 378–521), affecting 3·40 billion (3·20–3·62) individuals (43·1%, 40·5–45·9 of the global population); global DALY counts attributed to these conditions increased by 18·2% (8·7–26·7) between 1990 and 2021. Age-standardised rates of deaths per 100 000 people attributed to these conditions decreased from 1990 to 2021 by 33·6% (27·6–38·8), and age-standardised rates of DALYs attributed to these conditions decreased by 27·0% (21·5–32·4). Age-standardised prevalence was almost stable, with a change of 1·5% (0·7–2·4). The ten conditions with the highest age-standardised DALYs in 2021 were stroke, neonatal encephalopathy, migraine, Alzheimer's disease and other dementias, diabetic neuropathy, meningitis, epilepsy, neurological complications due to preterm birth, autism spectrum disorder, and nervous system cancer.InterpretationAs the leading cause of overall disease burden in the world, with increasing global DALY counts, effective prevention, treatment, and rehabilitation strategies for disorders affecting the nervous system are needed
