Published: March 2022

Abstract
We study the role of disorder in the vibration spectra of molecules and atoms in solids. This disorder may be described phenomenologically by a fractional generalization of ordinary quantum-mechanical oscillator problem. To be specific, this is accomplished by the introduction of a so-called fractional Laplacian (Riesz fractional derivative) to the Scrödinger equation with three-dimensional (3D) quadratic potential. To solve the 1 obtained 3D spectral problem, we pass to the momentum space, where the problem simplifies greatly as fractional Laplacian becomes simply k µ , k is a modulus of the momentum vector and µ is Lévy index, characterizing the degree of disorder. In this case, µ → 0 corresponds to the strongest disorder, while µ → 2 to the weakest so that the case µ = 2 corresponds to ”ordinary” (i.e. that without fractional derivatives) 3D quantum harmonic oscillator. Combining analytical (variational) and numerical methods, we have shown that in the fractional (disordered) 3D oscillator problem, the famous orbital momentum degeneracy is lifted so that its energy starts to depend on orbital quantum number l. These features can have a strong impact on the physical properties of many solids, ranging from multiferroics to oxide heterostructures, which, in turn, are usable in modern microelectronic devices.

Abstract
With increasing awareness of the importance of non-cystic fibrosis bronchiectasis, many patients seen will have modest changes on CT chest despite significant symptoms related to their disease. Variability in recognition of the CT changes has implications for the timely recognition of the disease and follow-up. Though very little data is published on longitudinal follow-up of patients with modest bronchiectasis and identifying factors which lead to progression of disease, there clearly are sub-groups of patients who require close follow from early in their disease trajectory. This study looks at whether a Web-based training improves recognition of bronchiectasis in a cohort with mild to moderate bronchiectasis.

Abstract
Bangladesh is still meaningfully needful on agriculture, and agriculture has an important connection with climate. Food security of Bangladesh is endangered by climate change. Forecasting future climatic condition is extremely vital for smart agricultural planning and familiarizing to climate change. Rabi (October-November to April-May), is one of the crop seasons of Bangladesh, many crops production depend on precipitation especially rice crops. In this study, we attempted to generate a precipitation map of Bangladesh divided into three phases: past (1970-2000), present (2000-2018), and future (2040-2060 or 2050) for January to April by forecasted precipitation results from GCMs of CMIP5 and CMIP6 and figure out possible change of precipitation. To assemble and analyze climate data and generate precipitation maps for January to April, we use GIS techniques such as raster statistics, raster extraction, and zonal statistics. In all month’s precipitation will be increased in compare to present condition, except April month. Like the present situation in 2050 eastern side of Bangladesh will have the highest precipitation area and the lowest precipitation area will be the north-western side of Bangladesh.

Abstract
Despite the discovery of vaccines, control and prevention efforts relied on non-pharmaceutical interventions (NPIs) for the novel Coronavirus disease 2019 (COVID-19). This article describes the process of development and application of the public health law in prevention and control of the COVID-19 pandemic in Uganda.Methods: A process evaluation of Uganda’s experience with enacting COVID-19 Rules. Briefly, the Public Health Act Chapter 281 (1935) was reviewed each time there was a revision of the NPIs during the COVID-19 outbreak. The study assessed how and what rules were developed, their influence on the outbreak progress and cases of litigation. The data sources were applicable laws and policies, Presidential speeches, cabinet resolutions, statutory instruments, the COVID-19 situation reports and registry of court cases that contributed to a triangulated analysis.Results: Uganda applied four of COVID-19 broad Rules for the period March to October 2021. These Rules were amended twenty–one (21) times realigned along the pandemic curve, had an expiry period, and were preceded by Presidential pronouncements and directives. The Minister of Health enacted the Rules which were followed by response teams, enforcement agencies, and the general population. The enactment of COVID-19 Rules was necessary but not sufficient to control the pandemic, hence other laws came into play, specifically the Uganda Peoples Defense Forces Act No. 7 of 2005, the Public Finance Management Act No. 3 of 2015, and the National Policy for Disaster Preparedness and Management. Enacting COVID-19 Rules attracted specific litigation arising from perceived infringement on certain human rights provisions.Conclusions: It is possible for low-income countries to enact supportive legislation within the course of a COVID-19 outbreak. The balance of human rights infringements would be an important consideration in future studies.

Abstract
Purpose: Pregnancy is a period in a woman’s life which has important consequences on oral health, particularly for gingival health. The present study aimed to evaluate the way in which periodontal disease (gingivitis and periodontitis) evolves during pregnancy and to identify women at higher risk of developing gingivitis and periodontitis during late pregnancy.Methods: A prospective cohort study was conducted in southern Spain, with 147 pregnant women who were assessed during the first and third trimesters of gestation in a public hospital. Data regarding gingival and periodontal health, oral hygiene and overall health status (obesity and diabetes mellitus) were collected. Reporting followed STROBE checklist.Results: A significantly higher number of women had periodontal and gingival disease in the third trimester of gestation compared with in early pregnancy. In the third trimester of gestation, 42 (28.6%) and 63 (42.9%) of women presented symptoms of periodontal disease and gingival disease, respectively. Obesity (OR: 2.834; 95%CI 0.919-8.741), worse oral hygiene during the first trimester of gestation (OR: 4.031; 95%CI: 2.12-7.65) and periodontal disease during early pregnancy (OR: 15.104; 95%CI: 3.60-63.36) most effectively predicted periodontal disease during late pregnancy.Conclusions: Pregnancy is associated with exacerbated periodontal and gingival disease symptoms throughout the different trimesters of gestation. Obesity and oral hygiene during early pregnancy were the risk factors that most contributed to the aforementioned changes in periodontal disease.
Nonparametric approximation of conditional risk in nonstationary geostatistical processes
Authors: Fernández-Casal Rubén , Castillo-Páez Sergio , Francisco-Fernández Mario 
Published: March 2022

Abstract
A nonparametric procedure to estimate the conditional probability that a geostatistical process exceeds a certain threshold value is proposed. The method consists of a bootstrap algorithm that combines conditional simulation techniques with nonparametric estimations of the trend and the variogram. The nonparametric local linear estimator, considering a bandwidth matrix selected by a method that takes the spatial dependence into account, is used to estimate the trend. The variogram is approximated by a flexible bias-corrected estimator based on the residuals. The proposed method allows to obtain estimates of the conditional exceedance risk in non-observed spatial locations. The performance of the approach is analyzed by simulation and illustrated with the application to a real data set.

Published: March 2022

Abstract
Background: A meta-analysis was conducted to study the efficacy of sexual stimulation during the conservative treatment of distal ureteral stones. Methods: All randomized controlled trials (RCTs) devoted to comparing the efficacy of sexual stimulus and placebo in treatment of distal ureteral stones were searched from PubMed, Web of Science, Cochrane Library and Google Scholar. The retrieval time ranged from the inception to December 31, 2021. RevMan 5.3 software was used to conduct the statistical analysis. Clinical efficacy was evaluated by the stone passage rate and time and analgesic use. Results: A total of 6 RCTs comprising 535 cases of distal ureteral stones were included. 273 cases were associated with sexual intercourse or masturbation 3-4 times a week, and 262 cases received only conventional medical treatment. The pooled results showed that the 2-week (RR = 1.77, 95% CI [1.34, 2.33]) and 4-week (RR = 1.48, 95% CI [1.29, 1.69]) expulsion rates of the intervention group were significantly higher than in the control group (ps<0.01). Additionally, sexual stimulation was associated with a shorter expulsion time (WMD = -3.74, 95% CI [-6.27, -1.22], p<0.01) and a decreased prevalence of renal colic attacks (WMD = -0.61, 95% CI [-1.01, -0.22], p<0.01). Conclusion: Proper sexual stimulation, such as sexual intercourse or masturbation 3-4 times weekly, can enhance the spontaneous expulsion of distal ureteral stones in patients presenting tolerable pain.
Spatial transformation dynamics of urbanization and refugees’ settlements in Bangladesh: A mixed approach in case of new Rohingya camps in Cox’s Bazar

Published: March 2022

Abstract
New human settlement has a robust inter-linkage to the spatial dynamics in local and regional contexts. This study aims to explore the spatial dimension of urbanization in a regional transition context focusing on the newly built refugee camp in the south-eastern coastal area of Bangladesh. For locational proximity and comparatively easy escape from Myanmar, over one million Rohingya have settled in the rural/forest area in Cox’s Bazar. However, ⁓80% of refugees live in ⁓745 hectares. Many organizations’ employees work for refugee crises, live near the camps area. Analysis openly available data sources from historical built-up expansion from 1975 to 2021 suggests that refugee settlements impact spatial development and population dimensions, which have a transition (rural-to-urban) of a greater regional scale than local urbanization. Results from an expert-based key informant study have broad agreement with the quantitative findings. However, environmental, socio-economic, and cultural impacts are more local than GIS findings. Therefore, local development policies need an urgent adjustment to comply with the local and regional balances in the above factors. Further investigations in scenario-based urbanization dynamics are required to avoid an urban-desert initiated in the absence or relocation of refugee settlement, one of the priorities policies of the Bangladesh’s Government.

Abstract
Diabetic wound is the leading cause of non-traumatic amputations in which oxidative stress and chronic inflammation are main factors affecting wound healing. Although conventional mesenchymal stem cells (MSCs) living material can promote skin regeneration, they are still vulnerable to oxidative stress which limits their clinical applications. Here, we have prepared (lactic-co-glycolic acid) (PLGA) nanofibers electrospun with LPS/IFN-γ activated macrophage cell membrane with the capacity to immunostimulate bone marrow derived mesenchymal stem cells (BMMSCs) and investigated the effects of this living material on diabetic wound healing. After defining the physic-chemical properties of LPS/IFN-γ activated RAW264.7 cell(a mouse M1 macrophage cell line model) membrane modified nanofibers (RCM-fibers), including surface molecule, diameter, hydrophilicity and degradation rate, we demonstrated that the RCM-fibers not only improved BMMSC proliferation and keratinocyte migration upon oxidative stress in vitro, but also accelerated BMMSCs-mediated wound closure with rapid re-epithelialization, collagen remodeling, immunoregulation, antioxidant stress and angiogenesis in experimental diabetic wound healing in vivo. Transcriptome analysis revealed the up-regulation of genes related to wound healing in BMMSCs upon RCM-fiber immune-stimulation. Enhanced healing capacity of RCM-fiber-BMMSCs living material was partially mediated through CD200-CD200R interaction. Similarly, LPS/IFN-γ activated THP-1 cell(a human M1 macrophage cell line model) membrane coated nanofibers (TCM-fibers) exhibited the similar improvement of human BMMSCs (hBMMSCs) on the diabetic wound healing in vivo. Our results thus demonstrate that LPS/IFN-γ activated macrophage cell membrane-modified nanofibers can in situ promote the biofunction of BMMSCs, making this novel living material promising in wound repair for human diabetes.
Data Replay Method for Detecting Fraud Concept Drift in Online Transactions

Published: March 2022

Abstract
The methods of online transaction fraud have never-ending changes and improvement. The classification accuracy of the static fraud detection model is reduced and the generalization ability of the model cannot be guaranteed. The focus of online transaction fraud detection is to make the classifier adapt to the new and old fraud concepts at the same time and to fully learn enough fraud characteristics. Therefore, this paper proposes a data stream classification algorithm based on cosine similarity to replay data (CSDR). Compare the cosine similarity between the data distribution after replaying the fraud concept data and the currently known data distribution to determine the amount of replay data at each moment of concept drift. Retain as much of the data distribution of the fraud concept as possible. To solve the problem of imbalance within the class, use the clustering over-sampling method to balance the dataset. Experiments on the credit card transaction data set show that the CSDR algorithm uses a single classifier to adapt to sudden and recurring concept drift. It has a higher average accuracy rate, lower replay data volume and model update time.
Here and there a trophoblast, a transcriptional evaluation of trophoblast cell models.
Authors: Cox Brian Joseph , Naismith Kendra 
Published: March 2022

Abstract
A recent explosion of methods to produce human trophoblasts and stem cells (hTSC) is fuelling a renewed interest in this tissue. The trophoblast is critical to reproduction by facilitating implantation, maternal physiological adaptations to pregnancy and the growth of the fetus through transport of nutrients between the mother and fetus. More broadly, the trophoblast has phenotypic properties that make it of interest to other fields. Its angiogenic and invasive properties are similar to tumours and could identify novel drug targets, and its ability to regulate immunological tolerance of the allogenic fetus could lead to improvements in transplantations. Within this review, we integrate and assess transcriptomic data of cell-based models of hTSC alongside in vivo samples to identify the utility and applicability of these models. We also integrate single-cell RNA sequencing data sets of human blastoids, stem cells and embryos to identify how these models may recapitulate early trophoblast development.
Effects of elevated temperatures and health status of the crustose coralline algae Hydrolithon boergesenii (Corallinales: Mastophoroideae) on the larval settlement of Diploria labyrinthiformis (Scleractinia: Faviinae)

Published: March 2022

Abstract
Crustose Coralline Algae (CCA) is a well-known settlement inducer for stony corals and, ultimately, recruitment, a vital component for reef growth and resilience. However, potential impacts of diseased CCA on larval settlement are not fully understood, especially on particular coral species. As oceans continue to warm, coral larvae need to be able to respond to settlement cues in elevated temperatures, yet the combined effects of thermal stress and CCA health status on larval behavior is not well known for most coral species. Here we assessed the effect of elevated temperatures and disease on the ability of the CCA Hydrolithon boergesenii to induce settlement of Diploria labyrinthiformis larvae. D. labyrinthiformis planulae were exposed to 4 substrate combinations (healthy CCA, diseased CCA, bare substratum, and bare tissue culture plate) and three temperatures (27.5°C, 29°C, and 31°C). Overall, settlement started earlier and was 1.5-3x higher at 31°C, regardless of CCA health status, but at this temperature, larval mortality increased two-fold in diseased CCA. Settlement differences between healthy and diseased H. boergesenii were only observed at 29°C, with healthy CCA facilitating twice as much settlement and having 3x lower mortality than diseased. Our findings suggest that, even though larvae can settle in both healthy and diseased CCA, temperature plays an important role in whether larvae will settle or perish. This study highlights the importance of healthy CCA to maintain and increase settlement and the ability of larvae to adapt to a warming ocean, contributing to the knowledge of D. labyrinthiformis larval ecology, valuable for larval rearing for restoration purposes.

Abstract
The purpose of this research was to develop an ecological risk based on effects of nano based toxicity on fish species posed by nanoparticles. Hardly few studies have reported the toxicity on Xiphophorus maculates. Therefore, the aim of this research is acute toxicity, accumulation and biochemical parameters (protein, carbohydrates and lipids) of green synthesized iron oxide nanoparticles on Xiphophorus maculates. Synthesized iron oxide nanoparticles were characterized by UV-Visible spectrophotometer, Scanning Electron Microscope, Energy Dispersive X-Ray Spectroscopy, Fourier Transform Infrared Spectroscopy and X-Ray Diffraction. LC50 (0, 10, 100, 500, 750 and 1000 ppm) of green synthesized iron oxide nanoparticles for 96 hrs and sub-lethal studies, platy was exposed to different concentrations (0, 100, 200, 300 and 400 ppm) of biosynthesized iron oxide nanoparticles for 7 days. Accumulation of iron oxide nanoparticles in gills increased based on concentration and biochemical parameters ( protein, carbohydrate and lipids) in muscle and gill platy were gradually abated with increased concentration of iron oxide nanoparticles. In conclusion, both acute and sub-lethal toxicity of green synthesized iron oxide nanoparticles more pronounced at higher concentration with two different periods. This is the first report on green synthesized iron oxide nanoparticles toxicity, accumulation and biochemical parameters using Xiphophorus maculates as a bioindicators.
Biosynthesis and Characterization of Silver Nanoparticles
Authors: Kah Glory , Njobeh Patrick 
Published: March 2022

Abstract
In this study, a quick, simple, cost-efficient, and green procedure for silver nanoparticles (AgNPs) biosynthesis was executed at 25°C using 5 easily accessible plants from Cameroon including Carica papaya, Achillea millefolium, Perilla frutescens, Ocimum gratissimum, and Garcinia kola. These plants served as capping and reducing agents, while the AgNO3 salt was the precursor. Initially, bioreduction of metallic Ag+ to Ag0 nanoparticles was established via a reduction in pH. Biosynthesis of AgNPs was primarily affirmed visually via a color change of the reaction mixtures with the ultraviolet–visible (UV-Vis) spectroscopy absorption peaks demonstrating that the synthesized particles were indeed AgNPs. X-ray diffractometry (XRD) showed the nanoparticles were crystalline in nature and had negative zeta potential (ζ-potential) values, which indicate they could be naturally stable. The phytochemical and Fourier transform infrared (FTIR) spectroscopic analyses revealed the possible phytochemicals in each aqueous plant extract responsible for reducing the Ag+ metallic ions to nanoparticles followed by capping and stabilization of the nanoparticles. The high-resolution transmission electrons microscopy (HRTEM) micrographs revealed nanoparticles of varying shapes and sizes. Also, micrographs from the scanning electron microscopy (SEM) showed clouds of polydispersed nanoparticles, which were confirmed by energy dispersive X-ray (EDX) spectroscopy to be highly composed of Ag, with strong optical peaks around 3 kV. The results thus validate that these AgNPs can be efficiently formulated using easily available tropical plants for safe applications in various sectors such as medicine and agriculture.
Recent Change in Summer Rainfall over the Tibetan Plateau: the Roles of External Forcing and Internal Variability
Authors: Ding Zhaomin , Zhai Panmao , Wu Renguang 
Published: March 2022

Abstract
During the recent decades, summer precipitation has increased over the western and northeastern Tibetan Plateau (TP) and decreased over the southeastern TP. This study investigates the effects of external forcing and internal variability on summer rainfall changes over the TP during 1979-2013. It is shown that the variations in atmospheric circulation and precipitation over the TP are largely contributed by the anthropogenic forcing and oceanic boundary conditions and that the Interdecadal Pacific Oscillation (IPO) plays an important role in TP summer rainfall changes on decadal time scales. The sea surface temperature (SST) anomalies in the tropical central-eastern Pacific induce a wave train consisting of anomalous cyclones and anticyclones over Eurasia. The anomalous anticyclone to the northeast TP weakens westerlies, facilitating the convergence of water vapor over the TP. Further analysis indicates that the IPO-related SST anomalies contribute partly to the uncertainty in simulations of summer rainfall changes over the TP in recent decades using a 40-member ensemble of the Community Earth System Model (CESM). Consequently, the IPO can be used as one of the predictive factors of TP summer rainfall on decadal time scales.
