Simultaneous Retrieval of Atmospheric Parameters Using Parallel Processing
Authors: Sparks L. , Patterson J. E. , Fanselow J. L. 
Published: February 2023

Remote sensing instruments to be flown on planned NASA missions will generate unprecedented quantities of data. It is essential that these data be processed rapidly and the results conveyed quickly to the scientific community. Such considerations mandate substantial advances in current techniques for analyzing data. In particular major improvements in both computation technology and numerical analysis methods are necessary. We examine the extent to which sequential parameter estimation can be used to automate and expedite the retrieval of atmospheric parameters from remote sensing data.
Our algorithm utilizes a square root information filter to retrieve the vertical profiles of trace gases from spectroscopic data. The algorithm permits simultaneous retrieval of many atmospheric parameters such as species abundance, atmospheric temperature, atmospheric pressure, and water vapor profiles. Implementation of this algorithm in a parallel processing environment should result in dramatic increases in the rate at which data can be analyzed.

Published: February 2023

Stratospheric aerosols resulting from the volcanic eruption of Mount Pinatubo have been observed in lidar measurements at Table Mountain, California (34.4° N, -117.7° W). Two separate lidar systems have been used to make measurements at four different wavelengths; 308 nm, 352 nm, 532 nm, and 1064 nm. A record of the evolution of the stratospheric aerosol loading, in terms of the backscatter ratio, as a function of time and altitude will be presented. The first evidence of the volcanic aerosols was on July 4, 1991, when increased backscattering, centered at approximately 17 km altitude, was observed. Until July 29, 1991, there was no indication of aerosols above 20 km altitude but since then there has been substantial variation and the stratosphere is sometimes essentially clear but on other occasions scattering ratios up to 10 (at 532 nm) have been observed. Large variations in the aerosol scattering have been observed, even on short time scales (10 min).
The presence of these aerosols has a profound effect on the ongoing measurements of stratospheric ozone profiles using the DIAL technique. Corrections for aerosol effects, which have generally been ignored for stratospheric measurements, should be included in the DIAL analysis. It would be useful at this point to obtain as much experimental information as possible concerning the differential scattering and extinction properties of this aerosol for the ozone DIAL wavelengths, otherwise the corrections can only be as good as the model used. Examples of recent results will be used to illustrate the effects. However, even though the ozone measurements are affected in the regions of the aerosol layers they appear to be unaffected in clear regions and ozone measurements up to 50 km altitude are still possible.

People living with HIV (PLHIV) admitted to hospital have a high risk of death. We systematically appraised evidence for interventions to reduce mortality among hospitalised PLHIV in low- and middle-income countries (LMICs). Using a broad search strategy with terms for HIV, hospitals, and clinical trials, we searched for reports published between 1 Jan 2003 and 23 August 2021. Studies of interventions among adult HIV positive inpatients in LMICs were included if there was a comparator group and death was an outcome. We excluded studies restricted only to inpatients with a specific diagnosis (e.g. cryptococcal meningitis). Of 19,970 unique studies identified in search, ten were eligible for inclusion with 7,531 participants in total: nine randomised trials, and one before-after study. Three trials investigated systematic screening for tuberculosis; two showed survival benefit for urine TB screening vs. no urine screening, and one which compared Xpert MTB/RIF versus smear microscopy showed no difference in survival. One before-after study implemented 2007 WHO guidelines to improve management of smear negative tuberculosis in severely ill PLHIV, and showed survival benefit but with high risk of bias. Two trials evaluated complex interventions aimed at overcoming barriers to ART initiation in newly diagnosed PLHIV, one of which showed survival benefit and the other no difference. Two small trials evaluated early inpatient ART start, with no difference in survival. Two trials investigated protocol-driven fluid resuscitation for emergency-room attendees meeting case-definitions for sepsis, and showed increased mortality with use of a protocol for fluid administration. In conclusion, ten studies published since 2003 investigated interventions that aimed to reduce mortality in hospitalised adults with HIV, and weren’t restricted to people with a defined disease diagnosis. Inpatient trials of diagnostics, therapeutics or a package of interventions to reduce mortality should be a research priority.

Progestogens for maintenance tocolysis in symptomatic women. A systematic review and meta-analysis
Authors: Ferrari Francesca , Minozzi Silvia , Basile Laura , Chiossi Giuseppe , Facchinetti Fabio 
Published: February 2023

Objective
Prevention of preterm birth (PTB) with progestogens after an episode of threatened preterm labour is still controversial. As different progestogens have distinct molecular structures and biological effects, we conducted a systematic review and pairwise meta-analysis to investigate the individual role played by 17-alpha-hydroxyprogesterone caproate (17-HP), vaginal progesterone (Vaginal P) and oral progesterone (Oral P).

Methods
The search was performed in MEDLINE, ClinicalTrials.gov and the Cochrane Central Register of Controlled Trials (CENTRAL) up to 31 October 2021. Published RCTs comparing progestogens to placebo or no treatment for maintenance tocolysis were considered. We included women with singleton gestations, excluding quasi-randomized trials, studies on women with preterm premature rupture of membrane, or receiving maintenance tocolysis with other drugs. Primary outcomes were preterm birth (PTB) < 37 weeks’ and < 34 weeks’. We assessed risk of bias and evaluated certainty of evidence with the GRADE approach.

Results
Seventeen RCTs including 2152 women with singleton gestations were included. Twelve studies tested vaginal P, five 17-HP, and only 1 oral P. PTB < 34 weeks’ did not differ among women receiving vaginal P (RR 1.21, 95%CI 0.91 to 1.61, 1077 participants, moderate certainty of evidence), or oral P (RR 0.89, 95%CI 0.38 to 2.10, 90 participants, low certainty of evidence) as opposed to placebo. Instead, 17-HP significantly reduced the outcome (RR 0.72, 95% CI 0.54 to 0.95, 450 participants, moderate certainty of evidence). PTB < 37 weeks’ did not differ among women receiving vaginal P (RR 0.95, 95%CI 0.72 to 1.26, 8 studies, 1231 participants, moderate certainty of evidence) or 17-HP (RR 0.86, 95%CI 0.60 to 1.21, 450 participants, low certainty of evidence) when compared to placebo/no treatment. Instead, oral P significantly reduced the outcome (RR 0.58, 95% CI 0.36 to 0.93, 90 participants, low certainty of evidence).

Conclusions
With a moderate certainty of evidence, 17-HP prevents PTB < 34 weeks’ gestation among women that remained undelivered after an episode of threatened preterm labour. However, data are insufficient to generate recommendations in clinical practice. In the same women, both 17-HP and vaginal P are ineffective in the prevention of PTB < 37 weeks’.

Published: February 2023

Objective
We evaluated the effect of moderate-intensity exercise intervention in children and summarized the optimal exercise intervention program.

Methods
Five significant databases, namely, Web of Science, PubMed, and China National Knowledge Infrastructure, were searched, and the literature was screened strictly according to the inclusion and exclusion criteria and analyzed using Stata 15.1 software.

Results
There were 25 studies from 22 articles, with a total of 2118 subjects included in the results. According to the meta-analysis, exercise intervention effectively improved children’s working memory [SMD = -1.05, 95% CI (-1.26, -0.84)] and cognitive flexibility [SMD = -0.86, 95% CI (-1.04, -0.69)], with a minor improvement in inhibitory control [SMD = -0.55, 95% CI (-0.68, -0.42)].

Conclusion
a) Improvements in children’s working memory and cognitive flexibility by moderate-intensity exercise interventions reached large effect sizes, and improvements in inhibitory control obtained moderate effect sizes. b) Better improvement in working memory for children aged 10 to 12 years than for children aged 6 to 9 years and better cognitive flexibility for children aged 6 to 9 years than for children aged 10 to 12 years. c) Exercise intervention programs lasting 8 to 12 weeks, 3 to 4 times/week, and 30 min/time are most effective in improving executive function in children.
Evaluating the feasibility and efficacy of a home-based combined high intensity interval and moderate intensity training program for increasing physical activity among low-active adults: A randomized pilot trial
Authors: Lewis Beth A. , Schuver Katie , Dunsiger Shira 
Published: February 2023

Background
High intensity interval training (HIIT), which includes short bursts of high-intensity physical activity (PA) followed by recovery, can increase PA by addressing time barriers and improving PA enjoyment. The purpose of this pilot study was to examine the feasibility and preliminary efficacy of a home-based HIIT intervention on PA.

Methods
Low active adults (n = 47) were randomly assigned to a home-based HIIT intervention or wait-list control lasting 12 weeks. Participants in the HIIT intervention received motivational phone sessions based on Self-Determination Theory and accessed a website that included workout instructions and videos demonstrating proper form.

Results
The HIIT intervention appears feasible based on retention, recruitment, adherence to the counseling sessions, follow-up rates, and the consumer satisfaction survey. HIIT participants reported more minutes of vigorous intensity PA at six weeks relative to control (no differences at 12 weeks). HIIT participants reported higher levels of self-efficacy for PA, enjoyment of PA, outcome expectations related to PA, and positive engagement with PA than the control.

Conclusions
This study provides evidence for feasibility and possible efficacy of a home-based HIIT intervention for vigorous intensity PA; however, additional studies are needed with larger samples sizes to confirm efficacy of home-based HIIT interventions.

Published: February 2023

Background
Food contamination by Staphylococcus spp. enterotoxigenic strains is quite common and despite underreporting caused by the short duration of clinical symptoms and lack of medical care, staphylococcal food poisoning is one of the most common Foodborne Diseases (FBD) in the world. This study describes a systematic review protocol with meta-analysis on the prevalence and types of staphylococcal enterotoxins in food, and the profile of contaminated foods.

Methods
The research will be conducted through the selection of studies reporting the analysis of staphylococcal enterotoxins in food contaminated by Staphylococcus spp. Searches will happen on the following databases: Medline (OVID), GALE, Science Direct, CAB Direct (CABI), Google Scholar, in addition to manual search in the list of references of articles, directory of theses and dissertations, and countries’ health agencies. Reports will be imported into the application Rayyan. Two researchers will independently select studies and extract data, and a third reviewer will solve conflicting decisions. The primary outcome will be the identification of staphylococcal enterotoxins in food, and the secondary outcomes will include staphylococcal enterotoxin types and foods involved. To assess the risk of bias in the studies, the tool developed by the Joanna Briggs Institute (JBI) will be used. For data synthesis, a meta-analysis will be performed. However, in case that is not possible, a narrative synthesis of the most relevant results will be carried out.

Discussion
This protocol will serve as the basis for a systematic review that aims to relate the results of existing studies on the staphylococcal enterotoxin prevalence and types in food, and the profile of the contaminated foods. The results will broaden the perception of food safety risks, highlight existing literature gaps, contribute to the study of the epidemiological profile and may guide the allocation of health resources for the development of preventive measures related.

Authors: Nitszke Agnieszka 
Published: February 2023

Po sześciu latach od zawiązania Inicjatywy Trójmorza można podjąć próbę określenia jej ról i funkcji, a także znaczenia, jakie ten proces ma dla integracji europejskiej, w szczególności dla Unii Europejskiej. Celem artykułu jest przedstawienie współpracy 3SI z perspektywy integralności polityki Unii Europejskiej oraz określenia, na jakie korzyści liczą państwa tworzące ten format w kontekście polityki unijnej. Zbadaniu zostanie poddana hipoteza mówiąca, że Inicjatywa Trójmorza nie stanowi wartości dodanej integracji europejskiej i jest forum realizacji interesów narodowych poszczególnych państw, a nie całej grupy. Aby rozstrzygnąć hipotezę postawiono następujące pytania badawcze: P1: Jakie były powody ustanowienia 3SI?; P2: które państwo lub państwa jest/są liderem grupy?; P3: Jakie państwa trzecie angażują się we wspieranie współpracy 3SI i jakie są ich motywacje?; P4: Jakie deklarowane i faktyczne role i funkcje w systemie UE wypełnia 3SI?
Analiza zostanie poprowadzona z perspektywy teorii europeizacji. W badaniu zastosowano metody jakościowe, w tym metodę instytucjonalno-prawną, systemową oraz komparatystyczną.

Feasibility assessment of injection molding online monitoring based on oil pressure/nozzle pressure/cavity pressure
Authors: Tsou Hao-Hsuan , Huang Chung-Ching , Wang Zhi-Hao , Zhao Ting-Wei 
Published: February 2023

Abstract
This study produced a box-like product through injection molding, and pressure sensors were installed at the nozzle in the injection molding machine and mold cavity. Injection molding experiments were conducted with various process parameters to understand the correlations between the pressure of the cavity, nozzle, and oil pump. A high correlation (R > 0.95) between oil pressure and nozzle pressure could be found in the study. The oil pressure in the injection molding machine could fully describe the pressure variation of the molten plastic at the nozzle. However, the correlation between nozzle pressure and cavity pressure was slightly reduced due to changes in injection speed, melting temperature, and packing time. Thus, a suitable molding window can improve the correlation between oil pressure, nozzle pressure, and cavity pressure. This study provides a correlation between the three pressures and a reference for the future selection of process variables, an essential pretreatment for online monitoring.
Two-dimensional EMD with shape-preserving spline interpolation
Authors: Brown Wesley G. , van der Walt Maria D. 
Published: February 2023

Abstract
Empirical mode decomposition (EMD) is a popular, user-friendly, data-driven algorithm to decompose a given (non-stationary) signal into its constituting components, utilizing spline interpolation. This algorithm was first proposed in 1998 in the one-dimensional setting, and it employed standard cubic spline interpolation. Since then, different two-dimensional extensions of EMD have been proposed. In this paper, we consider one of these two-dimensional extensions and adapt it to use a shape-preserving interpolation scheme based on quadratic B-splines, ensuring that monotonicity and concavity in the input data are preserved. Using multiple numerical experiments, we show that this new scheme outperforms the original EMD, both qualitatively and quantitatively.
Community-wide collaboration is a must to reinstall trust in bioinformatics solutions and biomedical interpretation
Authors: Takan Savaş , Allmer Jens 
Published: February 2023

Abstract
Science has become a highly competitive undertaking concerning, for example, resources, positions, students, and publications. At the same time, the number of journals presenting scientific findings skyrockets while the knowledge increase per manuscript seems to be diminishing. Science has also become ever more dependent on computational analyses. For example, virtually all biomedical applications involve computational data analysis. The science community develops many computational tools, and there are numerous alternatives for many computational tasks. The same is true for workflow management systems, leading to a tremendous duplication of efforts. Software quality is often of low concern, and typically, a small dataset is used as a proof of principle to support rapid publication. Installation and usage of such tools are complicated, so virtual machine images, containers, and package managers are employed more frequently. These simplify installation and ease of use but do not solve the software quality issue and duplication of effort. We believe that a community-wide collaboration is needed to (a) ensure software quality, (b) increase reuse of code, (c) force proper software review, (c) increase testing, and (d) make interoperability more seamless. Such a science software ecosystem will overcome current issues and increase trust in current data analyses.
Efficient mutual authentication using Kerberos for resource constraint smart meter in advanced metering infrastructure
Authors: Hasan Md Mehedi , Ariffin Noor Afiza Mohd , Sani Nor Fazlida Mohd 
Published: February 2023

Abstract
The continuous development of information communication technology facilitates the conventional grid in transforming into an automated modern system. Internet-of-Things solutions are used along with the evolving services of end-users to the electricity service provider for smart grid applications. In terms of various devices and machine integration, adequate authentication is the key to an accurate source and destination in advanced metering infrastructure (AMI). Various protocols are deployed to lead the identification between two parties, which require high computation time and communicational bit operations for system development. Therefore, Kerberos-based authentication protocols were designed in this study with the assistance of elliptic curve cryptography to manage the mutual authentication between two parties and reduce the time and bit operations. The protocols were evaluated in a widely adopted tool, AVISPA, which builds an understanding of the proposed protocol and ensures mutual authentication without unauthorized knowledge. In addition, upon comparing security and performance assessments to the current schemes, it was found that the protocol in this study required less time and bits to transmit information. Consequently, it effectively provides multiple security features making it suitable for resource constraint smart meters in AMI.
