A survey of accepted authors in computer systems conferences
Authors: Frachtenberg Eitan , Koster Noah 
Published: September 2020

Computer Science researchers rely on peer-reviewed conferences to publish their work and to receive feedback. The impact of these peer-reviewed papers on researchers’ careers can hardly be overstated. Yet conference organizers can make inconsistent choices for their review process, even in the same subfield. These choices are rarely reviewed critically, and when they are, the emphasis centers on the effects on the technical program, not the authors. In particular, the effects of conference policies on author experience and diversity are still not well understood. To help address this knowledge gap, this paper presents a cross-sectional study of 56 conferences from one large subfield of computer science, namely computer systems. We introduce a large author survey (n = 918), representing 809 unique papers. The goal of this paper is to expose this data and present an initial analysis of its findings. We primarily focus on quantitative comparisons between different survey questions and comparisons to external information we collected on author demographics, conference policies, and paper statistics. Another focal point of this study is author diversity. We found poor balance in the gender and geographical distributions of authors, but a more balanced spread across sector, experience, and English proficiency. For the most part, women and nonnative English speakers exhibit no differences in their experience of the peer-review process, suggesting no specific evidence of bias against these accepted authors. We also found strong support for author rebuttal to reviewers’ comments, especially among students and less experienced researchers.

Published: September 2020

BackgroundGlioma is the most common form of primary malignant intracranial tumor.MethodsIn the current study, miRNA matrix were obtained from the Chinese Glioma Genome Atlas (CGGA), and then univariate Cox regression analysis and Lasso regression analysis were utilized to select candidate miRNAs and multivariate Cox regression analysis was applied to establish a miRNA signature for predicting overall survival (OS) of glioma. The signature was assessed with the area under the curve (AUC) of the receiver operating characteristic curve (ROC) and validated by data from Gene Expression Omnibus (GEO).ResultsEight miRNAs (miR-1246, miR-148a, miR-150, miR-196a, miR-338-3p, miR-342-5p, miR-548h and miR-645) were included in the miRNA signature. The AUC of ROC analysis for 1- and 3-year OS in the CGGA dataset was 0.747 and 0.905, respectively. In the GEO dataset, The AUC for 1- and 3-year was 0.736 and 0.809, respectively. The AUC in both the CGGA and GEO datasets was similar to that based on WHO 2007 classification (0.736 and 0.799) and WHO 2016 classification (0.663 and 0.807). Additionally, Kaplan–Meier plot revealed that high-risk score patients had a poorer clinical outcome. Multivariate Cox regression analysis suggested that the miRNA signature was an independent prognosis-related factor [HR: 6.579, 95% CI [1.227−35.268],p = 0.028].ConclusionOn the whole, in the present study, based on eight miRNAs, a novel prognostic signature was developed for predicting the 1- and 3- year survival rate in glioma. The results may be conducive to predict the precise prognosis of glioma and to elucidate the underlying molecular mechanisms. However, further experimental researches of miRNAs are needed to validate the findings of this study.

Published: September 2020

Background and Aims: Women in the childbearing period on hemodialysis (HD) have decreased fertility when compared with the general population. However, pregnancy in this patients’ population is still possible. The aim of the current study was to assess the conception rate in Egyptian HD females.
Methods: The study comprises 2 phases: phase one studied the frequency of conception in HD females in Egypt, while phase two studied the live birth frequency and factors affecting it in 22 hemodialysis units (HDUs) including 211 females with sexually active partner in their childbearing period comprising 33 females with HD coincidental pregnancies.
Results: 5-year conception rate was 5.2%, and was associated with higher planned dialysis dose (higher blood flow rate, larger dialyzer size, and session length), better control of blood pressure, as well as a lower level of serum ferritin. Live birth frequency was 33.3% and was statistically significantly associated with younger age of the pregnant lady, higher length of dialysis sessions, lower serum phosphorus level, and suggested better nutrition. There was no maternal mortality associated with HD coincidental pregnancies. There was a better neonatal outcome observed with the caesarian section.
Conclusion: Fertility is possible and safe in Egyptian HD female with a sexually active partner as there is no maternal mortality but not as such for the fetal outcome. Better conception potentials and the outcome are related to better-planned dialysis dosing and adequate control of phosphate and inflammation.

Published: September 2020

Aims: Knowledge is currently low about composition, richness and abundance of native plant species from secondary forests in traditional communities in the Tapajós River Basin, Western Amazon. These forests are of great importance to indigenous populations being niches of resistance to the advances of monocultures. The objective of this work was to evaluate the floristic composition of a secondary forest with typical indigenous extractive interventions.
Study Design: The secondary forest studied located in indigenous Village. This forest had 15 years of natural regeneration and was therefore an anthropized forest, where the indigenous people removed wood, fibers, oils and fruits, thus characterizing the agroextractivism on this environment and a very particular floristic composition always in evolution.
Place and Duration of Study: The research was in Santarem city, Pará state, in Ipaupixuna Village (02°32´46” S, 54°20'15” W) between June 2019 to December 2019.
Methodology: The research had a descriptive approach for floristic study, but in the same time had a quantitative point of view with the use of regression analysis. The parameters evaluated were: 1. Species abundance, 2. Floristic Richness; 3. Plant diversity measured by the Jentsch Mixing Coefficient; 4. Relations between Circumference & Height of trees. The size of the sampled area was 1 (one) hectare of secondary forest.
Results: A high abundance was found for Tapirira guianensis Aubl followed by Buchenavia huberi Ducke and Bellucia grossularioides (L.) Triana. Fabaceae was the family of greatest quantitative expression in this 15-year-old secondary forest in indigenous landscapes followed by Arecaceae.
Conclusion: The secondary forest studied of 15 years of natural regeneration and random anthropogenic interventions by agroextractivists activities of Munduruku Indigenous people showed medium floristic richness and low floristic diversity. Interventions to enrich this secondary forest with plant species with high economic potential can bring environmental and economic benefits to these indigenous people.

Published: September 2020

Aims: The health risk assessment of some toxic metals in groundwater in four selected towns of Delta State, Nigeria was confirmed by this study.
Methodology: Ninety six groundwater samples were obtained from sixty four hand-dug wells and thirty two boreholes between December 2016 and May 2017. Samples were analyzed for heavy metals using standard procedures. Data collected was subjected to descriptive and inferential statistics using the Statistical Package for Social Sciences (SPSS) for Windows version 22.0. Health Risk Assessment for Non cancer hazard and carcinogenic effects were determined.
Results: The HQ of Cr, Mn and Ni were below 1.0 indicating no threat to the water consumers while the HQ values for Pb, Cd and Cu were above 1.0 indicating risk to human health. The HI value was found to be greater than 1.0, indicating noncarcinogenic adverse effects. The estimated Lifetime of Carcinogenic Risks (LTCR) for Pb, Cr, Cd and Ni exceeded the predicted lifetime risk for carcinogens of 10−6 from ingestion pathway. The groundwater had higher risks of Cr and Cd as LTCR value in most sites were >10−4. The high LTCR should be given high priority as public health is concerned.
Conclusions: This study indicated possible non-carcinogenic and carcinogenic human health hazard from groundwater consumption in study area through oral consumption.

Published: September 2020

Optimum design and selection of storage type electric water heaters were analyzed for energy conservation. The thermal performance of a single tank electric water heater is compared with that of partitioned electric water heater for the same average domestic hourly hot water use pattern according to Becker’s profile. Both water heaters have the same volume capacity and total power rating while the temperature of the hot water was kept between 60 and 65oC. It is concluded that a partitioned electric water heater provides more hot water and reduces energy consumption whereas the upper part of the tank has 25% of the total volume and 75% of the total power rating.
To evaluate single tank and partitioned electric water heaters transient energy balance equations have been derived and solved. Some assumptions made and thermodynamic properties received to use the evaluate differential equations. To represent water heater models equations required data obtained from literature.

Published: September 2020

On account of evaluating and mapping the spatial distribution of some selected physicochemical attributes of soil including the percentage of sand, silt and clay, textural class, soil reaction (pH), electrical conductivity (EC), and organic matter contents over a period of last 20 years, an investigation was carried out at cyclone-afflicted Shyamnagar sub-district, Satkhira, Bangladesh. Particle size analysis was examined by following the hydrometer method, whereas pH and EC were determined instrumentally. The carbon content of the soils was examined volumetrically by the wet-oxidation method. The amount of sand was less than the silt and clay fractions in the studied sites. Silt contents were significantly increased for over 20 years. Consequently, siltation has been taken place for the last two decades. Soil salinity was associated with the development of silt texture, altered from clay loam texture. The field moisture contents were observed to be increased (52%) which attributed to the increase of clay content with depth. Investigation revealed a very slow to moderate soil permeability class. An incremental trend (4.55% to 27.27%) of pH and EC (12.25 to 46.40 mS/cm) was noticed in the present study in contrast to the study of 1996. Alongside, corresponding spatial variability maps of the selected chemical soil properties were plotted by applying the Inverse distance weighting (IDW) interpolation method. Results demonstrated the southern, southeastern, and southwestern corners of the study area were experienced greater clay content, alkalinity, and significant depletion of organic matter. This situation might become worsened in near future. Moreover, the adoption of several effective countermeasures should be taken in this cyclone-affected soil to alleviate the soil salinity, improve soil health, and thereby deal with a more variable climate.

Published: September 2020

Aims: To evaluate the effect of a video educational intervention, on the knowledge of physicians and pharmacists with respect to their awareness of the difference between local bush medicines (bush) and imported herbal medicines (herb); and, their uses, side effects, contraindications and drug interactions. Also, to determine if there was exposure to and an interest in formal training on Complementary, Alternative and Bush Medicine (CABM).
Study Design: A cross-sectional study of registered pharmacists and physicians in Guyana, attending their annual conferences, was carried out with a self-administered survey questionnaire on medicinal plants.
Methodology: Participants completed the Pre-Questionnaire; then were shown a video and subsequently given a similar Post-Questionnaire. The impact of the video was investigated using Confirmatory Factor Analysis (CFA), Wilcoxon Sign Rank tests and logistic and multinomial regression models.
Results: A total of 274 (134 pharmacists and 140 doctors) persons participated. The bush which most were aware of, was corilla/bitter melon, both in the pre-questionnaire (60%) and in the post-questionnaire (83%). Cranberry (pre-score 48%, post-score 51%) was the most identified herb. A comparison of the pre and post scores using the paired t-test (t=2.528, df=175, P=0.005) indicated improved awareness. Most persons were able to identify one use of corilla/bitter melon (pre-score 61%, post-score 70%). However, for the other bush/herbs, and for the side effects, contraindications and drug interactions, knowledge was lacking although there were significant improvements after the intervention. 44% indicated that CABM was part of their formal training and pharmacists were more likely to have had formal training. 88% were interested in further training.
Conclusion: The study found a paucity of knowledge about medicinal plants and therefore strongly recommends implementing formal education on CABM in university curricula and in future Continuing Education (CE) sessions. The video intervention had a significant impact and should be used as a template.

Cardiac sympathetic innervation and vesicular storage in pure autonomic failure
Authors: Goldstein David S. , Isonaka Risa , Holmes Courtney , Ding Yu‐Shin , Sharabi Yehonatan 
Published: September 2020

AbstractObjectivePure autonomic failure (PAF) is a rare disease characterized by neurogenic orthostatic hypotension (nOH), absence of signs of central neurodegeneration, and profound deficiency of the sympathetic neurotransmitter norepinephrine. Reports have disagreed about mechanisms of the noradrenergic lesion. Neuropathological studies have highlighted denervation, while functional studies have emphasized deficient vesicular sequestration of cytoplasmic catecholamines in extant neurons. We examined both aspects by a combined positron emission tomographic (PET) neuroimaging approach using 11C‐methylreboxetine (11C‐MRB), a selective ligand for the cell membrane norepinephrine transporter, to quantify interventricular septal myocardial noradrenergic innervation and using 18F‐dopamine (18F‐DA) to assess intraneuronal vesicular storage in the same subjects.MethodsSeven comprehensively tested PAF patients and 11 controls underwent 11C‐MRB PET scanning for 45 minutes (dynamic 5X1’, 3X5’, 1X10’, static 15 minutes) and 18F‐DA scanning for 30 minutes (same dynamic imaging sequence) after 3‐minute infusions of the tracers on separate days.ResultsIn the PAF group septal 11C‐MRB‐derived radioactivity in the static frame was decreased by 26.7% from control (p = 0.012). After adjustment for nonspecific binding of 11C‐MRB, the PAF group had a 41.1% mean decrease in myocardial 11C‐MRB‐derived radioactivity (p = 0.015). The PAF patients had five times faster postinfusion loss of 18F‐DA‐derived radioactivity (70 ± 3% vs. 14 ± 8% by 30 minutes, p < 0.0001). At all time points after infusion of 18F‐DA and 11C‐MRB mean 18F/11C ratios in septal myocardium were lower in the PAF than control group.InterpretationPAF entails moderately decreased cardiac sympathetic innervation and a substantial vesicular storage defect in residual nerves.

AbstractSolar‐thermal materials have been intensively studied in the context of production and localization of thermal energy, targeting an industry level application. Although photonic and optical strategies for enhancing light absorption have increased the efficiency of photo excitation/conversion into thermal energy, most of them have several limitations such as large area fabrication, thermal stability and broadband/omnidirectional light absorption. In this study, a gold‐coated hierarchical nanoturf membrane (Au/h‐Nanoturf membrane) incorporated with randomly distributed high aspect ratio (AR) nanostructures and micro‐through holes is proposed. The Au/h‐Nanoturf has peculiar black structures that provide advantages in forming a membrane with a large area and in absorbing broadband solar light spectrum. Furthermore, the membrane is combined with micro‐cone array which makes it exhibit exceptionally omnidirectional light absorption properties. Using computational analysis, it is confirmed that the micro‐cone array substantially contributes to the omnidirectional solar absorption irrespective of the wavelength. The optimized structural parameters for the maximum efficiency of the solar‐thermal materials are also found. The prepared solar‐vapor generator with the optimized structural features exhibits 91% average conversion efficiency under one sun condition. The efficiency is sustainable for up to four weeks. The highly efficient and omnidirectional broadband‐absorbing solar‐thermal membrane can be readily employed, targeting an industry level application.
