Abstract
Research into practical applications of magnetic skyrmions, nanoscale solitons with interesting topological and transport properties [1,2], has traditionally focused on two dimensional (2D) thin-film systems[3,4]. However, the recent observation of novel three dimensional (3D) skyrmion-like structures, such as hopfions [5], skyrmion strings (SkS) [6-9], skyrmion bundles [11] and skyrmion braids [12], motivates the investigation of new designs, aiming to exploit the third spatial dimension for more compact and higher performance spintronic devices in 3D or curvilinear geometries [13-15]. A crucial requirement of such device schemes is the control of the 3D magnetic structures via charge or spin currents, which has yet to be experimentally observed. In this work, we utilise real-space imaging to investigate the dynamics of a 3D SkS within a nanowire of Co8Zn9Mn3 at room temperature. Utilising single, nanoscale current pulses, we demonstrate current-induced nucleation of a single SkS, and a toggle-like positional switching of an individual Bloch point at the end of a SkS. The observations highlight the possibility to locally manipulate 3D topological spin textures, opening up a range of design concepts for future 3D spintronic devices.
CSO and Media Contributions to the Fight Against Corruption in Ghana’s Extractive Sector: A Political Economy Analysis
Authors: Ofosu-Peasah Gideon 
Published: January 2022

Abstract
Estimates show that Ghana losses approximately 30 percent of domestic revenue to corruption. Although losses due to corruption in Ghana’s extractive sector have not yet been quantified, the sector is plagued with incidents of corruption despite the country's commitment to international conventions, transparency mechanisms and best practices. A concerted efforts by state and non-actors is key to ease this canker. Understanding the role of CSOs and media in exposing corruption, promoting oversight and identifying the enablers and obstacles to their work is key to informing practise in the development space. This study examines the role of CSOs and media in the fight against extractive sector corruption. It identifies political economy factors that enable or hinder them in exposing corruption. Lastly, it identifies practical suggestions for surmounting the identified adverse political and economic factors. The research examines two cases of corruption, based on a desktop review and a survey of 11 state and non-state actors. A direct association between the role of CSOs and media and the level of corruption were established. Coalition building, using legal suits, sustaining advocacy, collaborations between media and CSOs are some enabling political economy factors identified. Inadequate resources to sustain advocacy, excessive duplicity of roles amongst oversight institutions, vested interests in extractive sector, inadequate prosecution of offenders by the legal system, inadequate evidence-based policy solutions by government, inadequate political will, limited access to information; little or no funding for legal action, increasing CSO and media employee turnover rates, are identified as some key political economy factors militating against efforts towards stemming corruption in Ghana’s extractive sector. These findings provide reliable information for CSOs and media in development practice, informs advocacy design, evaluates and improves media and CSO effectiveness in ridding the extractive sector of corruption.

Published: January 2022

Abstract
Introduction: Nutrition and exposure to various chemicals, including environmental pollution, insecticides, and plant phytoestrogens (having oestrogen-like effects), are environmental factors that affect puberty onset. We aimed to identify the effects of propolis on precocious puberty and the reproductive system in prepubertal female rats (ovary, endometrium, breast).Methods: Thirty-four 25-day-old prepubertal female Sprague-Dawley rats were included in the study. Rats were randomly divided into the propolis (n 17) and control groups (n 17). The primary endpoint was the number of rats that developed vaginal opening (It's a sign of puberty) at 12-day follow-up. In addition, the effect of propolis on ovary, uterus and breast tissue was evaluated.Results: Vaginal patency occurred earlier in the propolis group. At the same time, a greater number of rats developed vaginal opening. The number of ovarian follicles (in all follicles), endometrial thickness, and mammary gland secretory gland area were significantly higher in the propolis group than in the control group (p-values <0.001, <0.001, <0.001, respectively). In addition, Ki-67 activity in the endometrium, breast tissue and ovary was more intense in the propolis group compared to the control group (p-values <0.001, <0.001, <0.001, respectively).Conclusion: Propolis triggers precocious puberty in female rats, possibly by interacting with the oestrogen receptor. The mechanism of action of propolis should be considered before prescribing it. In addition, further studies are needed to explore the mechanism of action of propolis and to determine the component of propolis that triggers puberty.
Effect of Temperature and Germania on the Performance of Germania Doped Silica Fiber Raman Scattering Amplifier
Authors: El-den B. M. , zaghloul Adel 
Published: January 2022

Abstract
The Raman gain coefficient, the attenuations at signal and pump wavelengths and the refractive indices of both core and cladding of silica doped Germania optical fiber are functions of the Germania ratio, temperature and wavelengths. The Raman amplifier gain increases with Germania ratio but it decreases with temperature. Also, Raman gain either increases or decreases with signal wavelength. As the fiber core radius increases, the Raman gain decreases. The gain distribution through the amplifier length of dual pumps with power divided ratio (S=0.5) is better than that for the forward pump amplifier and the backward pump amplifier. The forward pump has a maximized gain but the backward pump has a minimized gain, while the dual pumps have both the maximum and minimized gains. The final amplifier gain for the three kinds of pumps with the same pump power (Pp) is equally.The pump wavelength (λp=1.4553μm) gives the biggest Raman gain at the center of wideband signal wavelength (λs=1.50 to 1.60μm). With λp =1.48μm, the gain increases with λs until λs=1.57μm and after that the gain decreases with λs and so with the above three kinds of pumps, gain fluctuations over the band wavelength of signal. The threshold pump power and gain saturation are studied.

Abstract
Background

Early diagnosis of malaria and treatment seeking behavior play key role in controlling and preventing further complication related to malaria disease. Aim of this study was to determine the responses on early malaria diagnosis and treatment seeking behavior among outpatient clients attending at Sekou toure regional referral hospital in Mwanza, Tanzania.
Methods

A cross-sectional study was conducted among outpatient client at Sekou-Touré regional referral hospital, convenient simple random sampling used and self-administered questionnaire were used to collect data and data was entered into Microsoft excel and then exported to SPSS version 25.0 for further analysis and presented on the percentages and table. The analysis of strength of relationships between categorical variables was conducted using the Chi-square test. A p-value of ≤ 0.05 was considered to be statistically significant.
Results

A total of 192 respondents completed the study with a response rate of 97.6%. The study revealed that Most of the respondents about 90.6% stated they would seek treatment from health facility when symptoms appear. However, only 6.3% seek treatment within 24 hours of onset of illness (p= 0.017). Half of respondents (50.5%) experienced malaria symptoms in the past six months and only 30% seek for treatment at health facility. Preference of health facility, (51%) respondents were going direct to pharmacy to buy medicine for self-treatment. Overall, cost of service, time consumed and distance of health facility especially health center shows significant with such delay.
Conclusion

A low proportion of malaria-suspected patients sought treatment within 24 h of fever onset compared to the national target. Distance from the health facility, cost of service and time consumed were found to be predictors of early treatment-seeking behavior for malaria. Strengthening strategies tailored to increasing awareness for communities about malaria, importance of going hospital and early treatment-seeking behavior is essential.

Abstract
Background

Nonalcoholic fatty liver disease (NAFLD) poses a substantial socioeconomic burden and is becoming the fastest-growing driver of chronic liver disease, potentially accompanied by a poor prognosis. We aim to elucidate the global and regional epidemiologic changes in NAFLD during the past thirty years and explore the relevant causes.
Methods

Data on NAFLD incidence, prevalence, death, and disability-adjusted life-years (DALYs) were extracted from the Global Burden of Disease Study 2019. In addition, we also investigated the correlation between the NAFLD burden and the social development degree. Finally, the associations of the three common comorbidities with NAFLD were determined.
Results

Globally, the incidence and prevalence of NAFLD both increased drastically from 1990 to 2019, mainly affecting young adults. Meanwhile, the deaths and DALYs increased significantly as well, dominating the aged group. However, the overall age-standardized death rate (ASDR) and DALY rate presented decreasing trends. Moreover, the sociodemographic index (SDI) appeared to have obvious negative associations with the age-standardized prevalence rate (ASPR), ASDR and age-standardized DALYs, indicating a more serious NAFLD burden in less developed regions. Finally, we found that the incidence and prevalence of NAFLD were positively related to those of diabetes mellitus type 2 (DM2), stroke and ischaemic heart disease (IHD).
Conclusions

NAFLD is leading to increasingly serious health challenges worldwide. Comprehensive acquisition of the epidemiologic pattern for NAFLD and the identification of high-risk comorbidities may help policy-makers and clinical physicians develop cost-effective prevention and control strategies, especially in countries with a high NAFLD burden.

Authors: Mokrani Khaoula , Kühn Christina , Tarchoun Neji 
Published: January 2022

Abstract
The main objective of this study was to assess responses of mid-early (Spunta) and mid-late (Bellini) potato cultivars to different temperature regimes during subsequent stages of potato growth. The impact of high temperature (25/22°C day/night), low temperature (18/16°C day/night) and intermediate temperature (20/18°C day/night) was evaluated for different growth stages. Data were obtained for photosynthesis, carbohydrates in leaves, stems and tubers as well as production parameters. Enzyme activities were determined for sucrose-phosphate synthase in leaves, acid invertase in stems and acid and neutral invertases in tubers. Gene expression levels of relevant sugar metabolizing enzymes was quantified.A detailed correlation analysis revealed a strong impact of the expression level of sugar metabolizing enzymes in leaves on the final number of tubers per plant.Whereas total tuber yield increases with temperature, the number of tubers per plant was highest under low temperature conditions. Our data suggest an important role of the temperature on the length of the different growth stages.

Published: January 2022

Abstract
Background
In this retrospective study we analyzed a consecutive series of patients affected by isolated radial head Mason III fractures and treated with an on-table reconstruction technique combined with miniplate internal fixation or prosthesis.
Methods
This study included 42 patients affected by isolated radial head Mason III fractures and treated between Jan 2012 and Jan 2019. Twenty-four patients (average age 45.6 years) were treated with an on-table reconstruction technique combined with miniplate internal fixation. The remaining 18 (average age 44.5 years) were treated with prosthesis. From a clinical point of view, we evaluated the patients according to the Broberg–Morrey scoring system and the (disabilities of the arm, shoulder, and hand) DASH questionnaire for parameters.
Results
We found similar results in both the groups according to Broberg–Morrey score system and the DASH questionnaire at the last follow-up. The scores of the prosthesis group were better than those of the internal fixation group at the 1st, 3rd, and 6th month follow-up post-operation.
Conclusion
Both the on-table reconstruction technique combined with the miniplate internal fixation and prosthesis can be effective in treating patients with isolated Mason III radial head fractures. There was no difference in elbow function between the two groups at the last follow-up; however, a prosthesis favors early functional recovery of the elbow.

Abstract
This paper proposes using a WiFi-based identification system, Wi-ID, to identify users from their unique hand gestures. Hand gestures from the popular game rock-paper-scissors are utilized for the system’s user authentication commands. The whole feature of three hand gestures is extracted instead of the single gesture feature extracted by the existing methods. Dynamic time warping (DTW) is utilized to analyze the amplitude information in the time domain based on linear discriminant analysis (LDA), while extract amplitude kurtosis (AP-KU) and shape skewness (SP-SK) are utilized to analyze the Wi-Fi signals energy distribution in the frequency domain. Based on the contributions of the extracted features, the random forests algorithm is utilized for weight inputs in the LSTM model. The experiment is conducted on a computer installed with an Intel 5300 wireless networking card to evaluate the effectiveness and robustness of the Wi-ID system. The experiment results showed the accuracy of the proposed Wi-ID system has a personal differentiation accuracy rate over 92%, and with an average accuracy of 96%. Authorized persons who performed incomplete hand gestures are identified with an accuracy of 92% and hostile intruders can be identified with a probability of 90%. Such performance demonstrates that the Wi-ID system achieved the aim of user authentication.
Large-Scale Background and the Role of Quasi-Biweekly Moisture Transport in the Extreme Yangtze River Rainfall in Summer 2020
Authors: Qi Yanjun , Zhang Renhe , Wang Zhuo 
Published: January 2022

Abstract
A severe flooding hit southern China along the Yangtze River in summer 2020. The floods were induced by heavy rains, and the associated dynamic and thermodynamic conditions are investigated using daily gridded rainfall data of China and NCEP-NCAR reanalysis. It is found that the summer rainfall over the Yangtze River Basin (YRB) experienced pronounced subseasonal variation in 2020, dominated by a quasi-biweekly oscillation (QBWO) mode. The southwestward-moving anomalous QBWO circulation was essentially the fluctuation of cold air mass related to the tropospheric polar vortex or trough-ridge activities over the mid-high latitude Eurasian in boreal summer. The large-scale southwestward-transport of cold air mass from mid-high latitudes and the northeastward-transport of warm and moist air by the strong anomalous anticyclone over the western North Pacific provided important circulation support for the heavy rainfall in the YRB. The quasi-biweekly anomalies of potential and divergent component of vertically integrated water vapor flux played a major role in maintaining the moisture during summer 2020. The diagnosis of moisture budget shows that the enhanced moisture associated with the quasi-biweekly fluctuation rainfall was primarily attributed to the moisture convergence. The convergence of QBWO specific humidity by the background mean flow and convergence of mean specific humidity by QBWO flow played dominant roles in contributing to the positive moisture tendency. In combination with an adiabatic ascent induced by the warm temperature advection, the boundary layer moisture convergence strengthens the upward transport of moisture from lower troposphere. The vertical moisture transport associated with boundary layer convergence was of critical importance in causing low-level tropospheric moistening, whereas the horizontal advection of moisture showed a negative effect during the anomalous quasi-biweekly summer rainfall in 2020.

Published: January 2022

Abstract
A comprehensive study was conducted to explore the concentration and distribution of heavy metals in farm soils and river sediments around a gold mining area in Fiji with particular emphasis on ecological and human health risks. Representative samples were acquired from farm sites in Matanagata Village and the Nasivi river, both situated around the Vatukoula gold mine limited (VGML), the largest operational gold mine in Fiji. Following aqua regia digestion and analysis by AAS, the average soil concentrations for Cu (110.4 mg kg–1), Cr (136.2 mg kg–1) and Cd (1.7 mg kg–1), and sediment concentrations for Pb (69.31 mg kg–1), Cd (1.82 mg kg–1), Cu (88.95 mg kg–1) and Cr (143.12 mg kg–1) were found to exceed the recommended guideline values. Based on the geo–accumulation index (Igeo) and enrichments factor (EF), the farm soils were moderately contaminated with Cd while the and sediments showed moderate to significant contamination with Pb, Ni and Cr. Ecological risk assessment confirmed moderate to considerable ecological risk in the metal–contaminated samples, with Cd and Pb generally presenting greater risk compared to other metals. Multivariate analyses including principal component analysis pointed to gold mining activities as a potential source for heavy metals in the area. Furthermore, human health risk assessment (HRA) indicated that while adults faced no significant carcinogenic or non–carcinogenic risks from metal exposure (HI < 1), children were at more risk from Co, Mn, Cr and Fe exposure, as well as potential carcinogenic risk from Cd (ILCR = 1.46E–04).
