ISIS's “Khorasan Project” in Afghanistan: New Challenges and Threats
Authors: Yashlavskii A.
Published: March 2023

Attempts to penetrate and consolidate in new territories made by supporters of the terrorist organization “Islamic State”* led to the creation of a “branch” of this international extremist network, acting under the banner of “global jihad”, in Afghanistan. The proclamation of the so-called “Khorasan province” was engendered by the confrontation of this militant group not only with the Western coalition, led by the US and the pro-American Afghan government that existed until August 15, 2021, but also with the Islamist Taliban movement. Moreover, the confrontation between IS-Khorasan Province (ISKP) and the Taliban* continued even after the latter returned to power. The supporters of the self-proclaimed “caliphate” managed to regain their strength after the withdrawal of foreign troops from the Afghan soil and now pose a quite tangible threat, carrying out bloody terrorist acts against the Taliban, representatives of ethnic and confessional minorities, and even against foreign objects. The article analyzes the features of the emergence of the “Khorasan project” of ISIS*, as well as the reasons for the enmity of this group towards the Taliban. The author also examines the prospects for the destructive activities of ISKP and its impact on the security situation both in Afghanistan itself and in the neighboring countries. The author concludes that ISKP does not have any sufficient potential to overthrow the Taliban* regime and come to power in Afghanistan. However, the activities of the terrorist group pose a great danger not only to this country, but to the entire region. *the organization is banned on the territory of the Russian Federation

Background: Sleeping Sickness, Human African Trypanosomiasis (HAT) is a vector- borne disease caused by Trypanosoma brucei (T.b). Sleeping sickness in Ethiopia was reported in 1967 for the first time. Recently in Southern parts of Ethiopia, in August 2022, five (5) cases of sleeping sickness (T. b. rhodesiense) were confirmed. Following this outbreak, the current investigation was aimed to identify the entomological and epidemiological drivers for the reemergence of HAT outbreak and recommend appropriate interventions.
Methods: A cross sectional study design with descriptive data analysis was used. Tsetse fly collection and blood samples from cattle animals were taken. NGU and bio-conical traps were used to determine the distribution (density and abundance) of the vector. About 10μl of blood was collected from the marginal ear vein of 301 cattle animals using the heparinized microhematocrit capillary. The parasite detection was carried out through vector dissection under binocular stereo-microscope (magnification of 60X) and microscopic examination from serum of Animals using the Buffy coat method.
Results: A total of 329 tsetse flies were captured and identified to Glosina (G.) pallidipes 259 (60.4%) and Glossina fuscipes 70 (16.3%). 188 (51.1%) of tsetse flies were collected from Dembagofa with 94 apparent density. Among all captured Tsetse flies, 39 (11.8%) of Tsetse were fed with high female apparent density in each ecological variation: wood land (51), Bush land (20) and grassland (11). Overall, the apparent density of tsetse fly was high in Wood land (93): G. pallidipes (76.5) and Bush land (36.5). Among all examined cattles for the presence of parasite, 9 cattles were detected positive with an overall prevalence of 3%. T. congolense 6 (2%) and T. vivax 1 (0.3%) with 2 (0.7%) suspected brucei. The parasite prevalence Trypanosoma was 4 (4.6%) in poor body condition (Bcs) cattle. The animals in the age range 5 - 9 years were infected high with 7 (5.3%) prevalence.
Conclusion: The current study revealed that there are high-risk factors that predispose the community to Human African Trypanosomiasis (HAT) due to the presence of two different species of Tsetse flies and many animal reservoirs. The transmissions of Human African trypanosomiasis (HAT) are related to environmental, Vector, and human factors. Further geographically expanded investigation should be conducted throughout the country.

Authors: Lin Wei-Kang , Tang Xiao-Wu , Zou Yuan , Liang Jia-Xin , Li Ke-Yi
Published: March 2023

To further explore the bearing capacity and sustainable construction of vacuum drainage pipe (VDP) piles, field tests were carried out to compare and analyze the ultimate single pile bearing capacity, pile side friction and pile end resistance of ordinary piles and vacuum drainage pipe piles. The effect of the VDP pile on energy conservation and emission reduction in practical projects is discussed. The results shows that the VDP pile basically eliminated the soil squeeze and did not cause excessive relative displacement of pile and soil after vacuum consolidation. The VDP pile enhances pile side friction resistance, resulting in a 17.6% increase in ultimate bearing capacity compared to traditional piles. The VDP pile method can reduce carbon emissions by 31.4% compared to traditional methods. This study provides guidance for the production and design of VDP piles in the future and demonstrates their potential for energy conservation and emission reduction benefits compared to traditional methods.
Memoryless Property of the Income Distribution as an Indication for Testing the Equality of Opportunity: Evidence from China (1978-2015)
Authors: Tao Yong
Published: March 2023

It has been well known that the exponential distribution is the only continuous distribution that has the memoryless property. Here, we observe that, if the exponential distribution dominates an economy as a probability distribution of income acquisition, then the memoryless property imposes equal opportunities on agents in this economy to acquire earnings. Based on this observation, we propose to identify the emergence of an exponential income distribution as a potential necessary condition for guaranteeing the equality of opportunity. Together with other conditions (such as social and economic mobility), it would promote equal opportunities for income acquisition among citizens. Empirically, we employ the latest data available from four representative market-economy countries (the United Kingdom, the United States, Canada, and China) to demonstrate that the exponential distribution is a stylized feature of the income structure of the low- and middle-income class, which occupies the great majority of populations. By contrast, the top income classes in these countries obey the Pareto distribution. To validate the relationship between exponential distribution and equal opportunity, we empirically show how the income structure of the low- and middle-income class in China (from 1978 to 2015) evolved towards an exponential distribution after the market-oriented economic reformation.

“Ashamed” to Put His Name to It: Monsanto, Industrial Bio-Test Laboratories, and the Use of Fraudulent Science, 1969–1985
Authors: Rosner David , Markowitz Gerald
Published: March 2023

One of the most well-documented episodes of scientific manipulation and overt fraud was the scandal involving Industrial Bio-Test Laboratories (IBT) in the 1970s and the chronic toxicity tests it conducted on behalf of Monsanto that ultimately led to the indictment and conviction of employees of IBT and the Monsanto Corporation. IBT, at the time the nation’s largest private laboratory, served a range of industries and government agencies. IBT conducted about 22 000 toxicology studies for scores of corporations, representing between 35% and 40% of all tests conducted in private labs in the country. IBT has been justly condemned for its fraudulent activities in the 1970s, but no one has looked at the relationship between the corporate funders of IBT’s research and its fraudulent practices. We use previously secret corporate documents that detail the role of IBT’s largest customer, Monsanto, which used fraudulent data to influence government. This material, revealed through legal discovery proceedings now under way regarding polychlorinated biphenyls (PCBs) and Roundup, show the long-lasting impact of Monsanto’s behavior on efforts to regulate large corporations as well as on the long-term effects on human health.

Análisis técnico-económico en la aplicación de celdas de combustible microbiana a escala industrial para el tratamiento de aguas residuales y producción de energía eléctrica
Authors:   , Mamani Zevallos Edson Raúl
Published: March 2023

Las celdas de combustible microbianos (CCM) son dispositivos con la capacidad de degradar compuestos orgánicos y en este proceso generar energía eléctrica, así demuestran ser una de las tecnologías más destacables para mitigar la demanda de agua tratada y energía eléctrica, así contribuyendo en la protección de medio ambiente. Los principales beneficios económicos de la implementación de esta a gran escala son la disminución en costos de energía usada en el tratamiento de AR, además el valor agregado (energía eléctrica), también se destaca la significativa disminución de biomasa y lodos a diferencia de tratamientos aeróbicos, logrando también la disminución de costos en tratamientos y disposición de estos. No para llegar a su práctica a gran escala aún se deben superar dificultades, entre estas destacan es el costo de los materiales, los ánodos y cátodos los cuales representan un 70% del costo total de implementación de la CCM, para ser llevados a gran escala deben estar basados en materiales moderadamente baratos y con un alto rendimiento energético, entre estos se destacarían los nanotubos de carbono y las esponjas de grafeno, ya que debido a sus grandes superficies específicas, excelente estabilidad y conductividad se perfilan como los materiales idóneos para la escalabilidad. Por otro lado, si bien el aumento de las dimensiones de la CCM provoca una disminución de la densidad de potencia, la conexión en serie y en paralelo de varias CCM sería la forma más eficiente de generar grandes cantidades de densidad de potencia y buena opción en el escalamiento.

Boosting human capacities: How vaccination behavior and intention relates to attitudes toward vaccination, Human Enhancement, and naturalness
Authors: Döbler Niklas Alexander , Carbon Claus-Christian
Published: March 2023

Background: Even if vaccinations are widely available, a considerable number of people reject them. As sophisticated biotechnologies capable of augmenting the human body's capacities, vaccinations are an instance of Human Enhancement (HE): The effort to use technologies to improve humans. Global vaccination efforts against SARS-CoV-2 evoke public concerns similar to those in the general HE debate, namely, naturalness and invasiveness. We explore these variables and their connection to vaccination behavior in the context of the COVID-19 pandemic.
Methods: We conducted an online survey (N = 314 persons) with 256 participants (81.5%) vaccinated against SARS-CoV-2 and n = 58 (18.5%) not vaccinated. Participants answered questions concerning their attitudes on nature and naturalness, willingness to use cognitive enhancement methods, HE, psychological effects of vaccination, and planned vaccination. Several Bayesian regression models were constructed to predict the willingness to use cognitive enhancement, attitudes toward vaccinations and HE, and whether people plan for further vaccination doses.
Results: Participants were more willing to use methods to improve cognitive abilities if considered natural, non-invasive, and not used frequently. A less affirmative attitude toward naturalness was also associated with more willingness to use. Effects were primarily moderated by vaccination status. Vaccinated and unvaccinated participants differed substantially, especially in measures that reflected the attitude toward naturalness and related phenomena. Participants did not assess vaccinations as a prime example of HE. Rating of vaccination as enhancement did not reliably predict attitude on vaccination nor HE. More affirmative attitudes toward naturalness and not being vaccinated were negatively associated with the attitude toward vaccinations and HE. A positive attitude toward HE predicted a more positive attitude toward vaccinations. Support of disease control measures and attitude toward vaccinations positively predicted vaccination intention. Receiving the vaccination led to psychological relief.
Conclusions: Motives of vaccination and HE refusal appear to be linked. Interventions considered unnatural and invasive are deemed unfavorable. These reasons seem more pronounced for unvaccinated participants. If HE, e.g., vaccination, constitutes an essential public health measure, concerns about the human relationship to nature, perceived naturalness, and sanctity of the human body must be sufficiently and thoughtfully addressed.
Non-contact human presence sensing technology based on WiFi signal
Authors: Xuechun Wang , Jinghao Wen
Published: March 2023

With the rapid development of Internet of things technology, people’s demand for adaptive non-contact sensing is growing. Aiming at the problems of traditional human perception technologies such as vision-based, poor sensor universality, and low accuracy, this paper proposes a new non-contact human presence perception technology based on WiFi, which sequentially preprocesses, extracts features, and classifies the collected channel state information, and establishes signal models corresponding to different states to realize human perception and recognition. Experiments show that the sensing accuracy of this method is high, up to 99 % , and it can be well applied in smart homes, medical care, and other life scenes.
Feminization of the health workforce in China: exploring gendered composition from 2002 to 2020
Authors: Li Mingyue , Raven Joanna , Liu Xiaoyun
Published: March 2023

Background
Feminization and gender diversity of the health workforce has been global documented and has stimulated wide discussion, but it has not been investigated in China. This study aims to analyze the change of the gendered composition of health workforce, and explore the trend in different professions and different health organizations within China’s hierarchical health system.
Methods
The data were collected from China Health Statistical Yearbook from 2002 to 2020. We focused on health professionals, doctors, nurses, pharmacists, and management staff in health organizations. Trend analysis was employed to examine the change in the ratio of female health workforce over 18 years. The estimated average annual percent change (AAPC) was estimated, and the reciprocals of variances for the female ratios were used as weights.
Results
The number of health professionals in China increased from 4.7 million in 2002 to 10.68 million in 2020. The number of health professionals per 1000 population increased from 3.41 in 2002 to 7.57 in 2020. The ratio of female health professionals significantly increased from 63.85% in 2002 to 72.4% in 2020 (AAPC=1.04%, 95%CI 0.96%-1.11%, P<0.001). Female doctors, pharmacists, and management staff increased 4.7, 7.9 and 3.5 percentage points from 2002 to 2020, respectively. Female health workers at township health centers, village clinics, centers for disease control and prevention had higher annual increase rate (AAPC=1.67%, 2.25% and 1.33% respectively) than those at hospital (0.70%) and community health center (0.5%). Female doctors in traditional Chinese medicine, dentistry and public health had higher annual increase rate (AAPC=1.82%, 1.53% and 1.91% respectively) than female clinical doctor (0.64%).
Conclusions
China’s health workforce is mainly composed of women, and has been feminizing steadily over the last 18 years. Health workforce in rural areas has been feminizing faster than urban areas. Marginalized professions like doctors in public health and traditional Chinese medicine have been feminizing at a faster speed than the prominent professions in clinical medicine. Gender equity， especially on pay gaps, should be considered in policies over the career course for health workforce to foster a more supportive environment to improve gender diversity.
Impulse Noise Suppression by Deep Learning-Based Receivers in OFDM System
Authors: Tseng Der-Feng , Lin Che-Shien , Tseng Shu-Ming
Published: March 2023

Due to inevitable corruption on signals across all subcarriers, strong and frequently occurring impulses pose a grim threat to Orthogonal Frequency Division Multiplexing (OFDM) systems, where system performance is likely to be further degraded by multipath fading phenomenon. Recently, a deep neural network (DNN) receiver is shown to be capable of not only implicitly estimating channel state information but also explicitly recovering the transmitted symbols without assuming the signal-to-noise ratio (SNR) level. In principle, the DNN model is trained using data generated from computer simulations–according to WINNER II channel model as fading channels, and the additive white Gaussian noise (AWGN) as background noise. As with its conventional peers which assume the inter- fering source from AWGN only, the aforementioned DNN receiver is prone to substantial performance loss when subject to impulse noise. To address this obstacle, this paper incor- porates the fine-tuning notion into the DNN model–by substituting impulse noise-laced data samples for succeeding training data–with an aim at enhancing representation learning. To attest the efficacy of the proposed DNN receiver, the bit error rate (BER) result derived from a compressive sensing-based receiver, enabled by consensus alternating direction method of multipliers (ADMM), is used as a benchmark for performance comparison. Noteworthily, the induced BER performance is comparable to that of the clipping-featured receiver, the threshold of which however solicits the knowledge of the SNR value, an assumption that is otherwise relaxed by the proposed DNN receiver. Furthermore, through extensive simulations, the deep learning based approach demonstrates promising robustness against impulse noise model mismatch between training and testing counterparts.

Background: Resistance training is recommended for post coronary by-pass artery graft (CABG) patients in addition to aerobic training as part of secondary prevention. However, there is a lack of studies that investigate the impact of resistance training on proprotein convertase subtilisin kexin 9 (PCSK9).
Aim: This study aims to assess the impact of intensive resistance training on PCSK9 level in post-CABG patients undergoing phase II cardiac rehabilitation.
Methods: In this randomized, prospective, open label trial, 87 post­CABG patients were assigned to moderate to high intensity resistance training and aerobic training (n=44) and aerobic training only (n=43) for 3­4 weeks. The primary endpoint was change of PCSK9 levels after cardiac rehabilitation program. Secondary endpoints include change of six-minute walk test (6-MWT) result, aerobic capacity, WHO­5 well­being index, fasting blood glucose and lipid profile. Intention-to-treat analysis was performed in both groups.
Results: After completion of phase II cardiac rehabilitation, mean PCSK9 levels in intervention group decreased significantly compared to control group (β=­55 ng/ml, 95%CI ­6.7 to ­103.3, p=0.026). This reduction was followed by significant improvement of 6-MWT result (β=28.2 m, 95%CI 2.4-53.9, p=0.033), aerobic capacity (β=0.9 Mets, 95%CI 0.1-1.7, p=0.021), and WHO­5 well­being index (β=8.1, 95%CI 2.0-14.4, p=0.011) in patients who performed resistance training in addition to aerobic training. There are no significant changes in fasting blood glucose, cholesterol, LDL­C, HDL-C, and triglyceride.
Conclusion: The addition of resistance training to aerobic training components in phase II cardiac rehabilitation significantly reduces PCSK­9 levels and increases patient’s functional capacity and quality of life. (NCT02674659)

There is a scarcity of large randomized clinical trials on the efficacy and safety of high-dose amino acid supplementation (AAS) in patients with gastrointestinal tumors undergoing surgical treatment. To investigate the effect of high-dose amino acid supplementation on the incidence of infection within 30 days after major surgery in patients with gastrointestinal tumors. In this randomized clinical trial, we randomly assigned patients with gastrointestinal tumors to receive either AAS or standard care (SC). The primary outcome was the 30-day postoperative incidence of infection; secondary outcomes included amino acid treatment-related adverse events, in-hospital infectious complications, postoperative hospital stay, other complications, and laboratory test results. We included 407 patients in the intention-to-treat analysis for the primary outcome (AAS group, 204; SC group, 203). During the intervention, the actual mean daily energy intake did not differ significantly between the AAS and SC groups (25.53 vs 25.16 kcal/kg daily, P = .493). However, the actual mean daily amino acid intake was significantly higher in the AAS group than in the SC group (1.81 vs. 0.94 g/kg daily, P < .001). The infection incidence within 30 days of surgery was significantly lower in the AAS group than in the SC group (P = .025). The incidence of amino acid treatment-related adverse events and other complications 30 days postoperatively did not significantly differ between the two groups. The infection incidence during hospitalization was significantly lower in the AAS group than in the SC group (P = .033). Compared to the SC group, the AAS group had significantly shorter postoperative hospital stays (P < .001). AAS is associated with a reduced infection incidence within 30 days of major surgery in patients with gastrointestinal tumors and can be a promising strategy.

Tuberculosis (TB) is a disease with a high burden, with most patients in low and middle income countries (LMIC). In Western countries however, this disease is rare, but with the increasing number of migrants it becomes more relevant. Especially in women with fertility issues, TB is not the most likely diagnosis and therefore difficult to discover and treat. If TB is not detected at an early stage, it can have major consequences for fertility and pregnancy outcomes. Screening should be suggested in women originated from high endemic countries with unexplained fertility loss, or during first trimester screening. QuantiFERON testing and PCR sampling for TB should be the golden standard. This case report describes fertility issues and an immature delivery in a young woman caused by extrapulmonary TB in the genital tract. With this case report, we hope to draw attention to this disease so that early detection can take place and serious outcome can be prevented.

With the rapid development of cities, the problem of environmental sustainability has become increasingly prominent, and it is increasingly important to build a socially resilient city. This research focuses on white pollution-the recycling of waste plastics in concrete in the city and the comfort of the urban living environment, from the perspective of concrete materials. Firstly, the proportion of recycled plastics, natural aggregate, water-cement ratio, and other parameters were optimized, and then the heat resistance, sound insulation, economic and environmental protection performance of the optimized concrete were studied. The results showed that the optimal proportion of recycled plastic concrete was obtained, and the strength deterioration mechanism was revealed. The maximum suitable use temperature of recycled plastic concrete is around 75 ℃. Recycled plastic concrete has better sound insulation performance for unsteady sound, human sound and mechanical sound. In terms of economic and environmental performance, the cost of raw materials of recycled plastic concrete is not dominant, and the water-soluble extracts have little impact on the environment. The research results are expected to provide a theoretical basis for the realization of urban environmental sustainable development.

Background
Community Mental Health Centers (CMHCs) provide mental health services to patients at low cost, with less stigma, in a domiciliary. This is the first study to describe demographic characteristics, common mental disorders, referral status, and treatment discontinuation in patients at the only CMHC of Mashhad, northeastern Iran.
Methods
This cross-sectional study enrolled 662 patients who contacted this center between January 2014 and December 2021. We completed a checklist that included information on demographics, diagnosed mental disorders, referral status, and the number of psychiatric visits, all of which psychiatrists fully completed clinical records. The frequency distributions of all variables were carried out with SPSS11.5. In addition, the association between epidemiological findings and patient referral (referral system or self-referral) and the association between epidemiological findings and the number of psychiatric visits were examined by the Chi-square test.
Results
Of 662 patients, 472 (71%) women and 190 (29%) men were enrolled, and the mean age of all patients was 29 years. Among the 475 adult patients, 367 (77.3%) patients were married and had primary or secondary education (40.4%), and the majority of them were housewives (56.4%). Major Depression Disorder (32%), Generalized Anxiety Disorder (18.3%) were the two most common mental illnesses in patients. Large proportions of the patients (70.7%) were referred to this center via the referral system. Moreover, non-working patients (housewives and unemployed patients) and the female gender were associated with more referrals to this center through the referral system. 431 patients (65.1%) did not return for a second visit, and the higher number of psychiatric visits was associated with a lower level of education.
Conclusions
Based on the results of this study, most of the patients in this center had a low socioeconomic level. Most of them were referred through the referral system, and gender and employment significantly contributed to referral via the referral system. The majority of patients discontinued treatment after the first psychiatric visit, and this was associated with the level of education.
