On Super Strong ETH
Authors: Vyas Nikhil , Williams Ryan 
Published: January 2021

Multiple known algorithmic paradigms (backtracking, local search and the polynomial method) only yield a 2n(1-1/O(k)) time algorithm for k-SAT in the worst case. For this reason, it has been hypothesized that the worst-case k-SAT problem cannot be solved in 2n(1-f(k)/k) time for any unbounded function f. This hypothesis has been called the "Super-Strong ETH", modelled after the ETH and the Strong ETH.
It has also been hypothesized that k-SAT is hard to solve for randomly chosen instances near the "critical threshold", where the clause-to-variable ratio is such that randomly chosen instances are satisfiable with probability 1/2. We give a randomized algorithm which refutes the Super-Strong ETH for the case of random k-SAT and planted k-SAT for any clause-to-variable ratio. For example, given any random k-SAT instance F with n variables and m clauses, our algorithm decides satisfiability for F in 2n(1-c*log(k)/k) time with high probability (over the choice of the formula and the randomness of the algorithm). It turns out that a well-known algorithm from the literature on SAT algorithms does the job: the PPZ algorithm of Paturi, Pudlak, and Zane (1999).
The Unique k-SAT problem is the special case where there is at most one satisfying assignment. Improving prior reductions, we show that the Super-Strong ETHs for Unique k-SAT and k-SAT are equivalent. More precisely, we show the time complexities of Unique k-SAT and k-SAT are very tightly correlated: if Unique k-SAT is in 2n(1-f(k)/k) time for an unbounded f, then k-SAT is in 2n(1-f(k)/(2k)) time.

Published: January 2021

Background: Stem cells are undifferentiated cells with a potential for self- renewal and differentiation into multiple mature cell types. PRP is blood plasma that has been enriched with platelets and multiple growth factors that can stimulate cellular processes and activate multi-potent stem cells to generate new, younger tissue and new blood vessels relevant to ovarian rejuvenation and endometrial regeneration.Methods: This study was to evaluate the effectiveness of ABMDSC and PRP application in patients with thin endometrium refractory to treatment, premature ovarian failure, infertility and menopause. 37 symptomatic women between age group 18 years to 56 years were selected for ABMDSC and PRP instillation in endometrium and/ or ovaries. PRP was instilled in endometrium in 8 patients, in ovaries in 5 patients and in both endometrium and ovaries in 24 patients.Results: There was significant improvement in endometrial thickness, along with improved blood flow to both endometrium and ovaries. FSH levels decreased and ovarian volume increased. There were three confirmed pregnancies with one delivery. Menopausal symptoms decreased in 2 patients and spontaneous resumption of menses was seen in 1 patient of POF.Conclusions: Stem cell therapy serves as a game changer with their unique properties, offering solutions for scores of women suffering from POF, poor oocyte quality, endometrial degeneration/ damage or menopausal symptoms.

Placental mesenchymal dysplasia (PMD) is a rare vascular anomaly which is characterized by mesenchymal stem villous hyperplasia and placentomegaly. Since the modality of treatment changes it is necessary to distinguish PMD from molar pregnancy, placenta mosaicism, chorioangioma, twin pregnancy with co-existent molar pregnancy. On reviewing cases of abnormal placental villus proliferation having features of placental mesenchymal hyperplasia placentomegaly and cystic appearance of placenta in database of our hospital from 2015-2019, we reported 4 cases of abnormal placental villous proliferation. And performed systematic review of existing literature. Provisional diagnosis of PMD was made as USG and placental morphology showed 30-60% of the placenta with cystic vesicles, placentomegaly with a normal growing fetus. PMD an uncommon vascular anomaly which resembles molar pregnancy but prognosis is different. The fetus was normal in majority of the cases. This clinical entity should be kept in mind to avoid unnecessary termination of pregnancy.

Published: January 2021

The outbreak of coronavirus disease 2019(COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is spreading globally at an accelerated rate. A serious public health threat, it has caused a major impact on health care systems with a significantly high mortality and morbidity. Physiological changes and immuno-compromised state make pregnant women vulnerable during infectious disease outbreaks and hence need a more cautious approach. With this report we aim to share our experience regarding clinical characteristics, management and outcomes of 10 diagnosed COVID-19 pregnant women undergoing cesarean section at Medicover hospital, a tertiary-care center in Hyderabad, India between July to September 2020. All 10 pregnant women were referred in their third trimester with diagnosis of COVID-19. 2 out of 10 patients had severe COVID-19 and were managed in the ICU. All patients underwent emergency cesarean sections and none of the infants were infected with COVID-19. At discharge, all patients and the newborns were in a clinically stable condition. Effective management strategies incorporating integrated team approach, early cesarean section and low-threshold for mechanical ventilation has been shown to be associated with favorable outcomes for mothers diagnosed with COVID-19 and their infants. Also, the present data does not support any evidence of vertical transmission of SARS-CoV-2 virus in those manifesting during the third trimester of pregnancy.

Published: January 2021

Purpose: The purpose of this study is to provide a model of hospital information system acceptance owned by the Social Security Organization.
Methodology: This study was performed Cross-sectional – applied and descriptively and analytically. This study had two stages. The study population was in the first stage (qualitative), information technology experts in the Social Security Organization (6 people) and the second stage (quantitative), users of the hospital information system in medical centres owned by the Social Security Organization (375 people). The first stage of this study was based on interviews with IT experts. The second stage of the study was based on the results of interviews with experts using the design of a researcher-made questionnaire. The validity of the questionnaire was measured by using the opinion of experts in the field of information technology and health information technology and by calculating the CVR index. Cronbach's alpha coefficient (0.941) was used to assess the reliability of the questionnaire. The questionnaire consisted of 12 axis and 46 questions with a five-point Likert scale with a score of 5-1. The interviews were analyzed qualitatively (content analysis) and the questionnaires were analyzed descriptively, analytically (correlation) and structural equation method is done with the help of SPSS software.
Main Findings: Evaluation of direct relationships between model factors and hypotheses showed that the relationships between habit with intent to use, intention to use with actual use, increase motivation to use, increase management support, meet user expectations in achieving the expected performance of the system, value the cost to the system and the social impact of co-workers significantly increases the intention to use the system. Also, the coefficient of determination R2 for the target variables, which is the intention of use and actual use, were equal to 0.774 and 0.448, respectively. The goodness of fit (GoF) was equal to 0.671. The study of the effect of demographic factors on the target variables (intention to use and actual use) showed that none of the demographic variables has a significant effect on the intention to use and actual use. By considering these factors, the managers of the Social Security Organization can increase the rate of HIS admission in the hospitals and clinics of this organization.
Application of Study: One of the technologies used in the healthcare sector is the hospital information system. It is less developed than other information systems that use information technology and apply quality standards for customer satisfaction. The IT acceptance model is one of the most valid models available that examines the acceptance factors of technology at different levels, including the individual level.
Novelty/Originality: The novelty of this research is giving a model of clinic data framework acknowledgement claimed by the Social Security Organization.
