Multi-objective allocation optimization of soil conservation measures under data uncertainty
Authors: Hildemann Moritz , Pebesma Edzer , Verstegen Judith Anne 
Published: June 2022

Abstract
Many regions worldwide face soil loss rates that endanger future food supply. The installation of soil and water conservation measures reduces soil loss rates but comes with high labor costs. A multi-objective optimization allows considering both soil loss rates and labor costs, but required spatial data contains uncertainties. Yet, spatial data uncertainty has not been considered in research for allocating soil and water conservation measures. We aim to overcome that research gap by optimizing conservation measure allocations despite spatial data uncertainties. We propose a multi-objective genetic algorithm that creates optimal solutions that indicate which watersheds should be conserved. Stochastic objective values are computed from uncertain soil and precipitation variables to evaluate and compare solutions. The study is conducted in three rural areas in Ethiopia. The highest soil loss rate uncertainties result in objective values ranging up to 14%. The associated yield loss ranges with soil loss rates under uncertainties are comparable to reported yield loss risks from droughts. The uncertainty of labor requirement objective values is localised to less then 5% of the area in all three study areas. However, ranges in labor requirement estimations become up to 15 labor days per hectare in areas where labor requirements are uncertain. Upon further analysis of common characteristics and patterns in optimal solutions, we also conclude that the results can be used to define a temporal order for planning and implementing conservation measures.
Dual-Polarized MIMO Antenna System for 5G Indoor base Station Applications
Authors: Surendra Loya , khan Habihulla 
Published: June 2022

Abstract
In this paper a dual-polarized multiple-input multiple-output (MIMO) antenna system for fifth-generation (5G) indoor base station applications resonating at 3.5 GHz has been proposed. The initial design is a conventional patch antenna, and characteristic mode analysis (CMA) is used to determine its dual-polarized characteristics. Both orthogonal modes are excited using the full-wave approach with a 50 Ohm dual-port coaxial feed line, and operated at 3.5 GHz. The non-contact feed method is used to improve isolation between ports. Inserting an air gap between the antenna substrate and the ground metal sheet improves gain and bandwidth. Further 2x2 MIMO antenna with 8-port is designed on low cost FR4 dielectric material with 120*120*5.17 mm3 compact volume. The MIMO antenna’s performance are examined by simulation and experimental. For the proposed MIMO, high isolation, high efficiency, and appropriate gain-level characteristics have been obtained. Furthermore, throughout the whole band of interest, the calculated total active reflection coefficient (TARC) and envelope correlation coefficient (ECC) of the antenna components are very low, indicating that the proposed multi-antenna systems are capable of enormous MIMO and diversity applications. Furthermore, the antenna avoids the use of complex feeding mechanisms such as baluns or directional couplers.

Published: June 2022

Abstract
Background
Whiles challenges associated with menstrual hygiene management among adolescents are universal, some sub-populations, such as deaf girls, have peculiar challenges that requires special attention. Although there have been numerous studies on menstrual hygiene management among adolescents in the school setting in Ghana, the experiences of students with disabilities, particularly, deaf girls have not attracted adequate scholarly attention.
Objective
The objective of the study was to generate new empirical evidence on menstrual hygiene management challenges of deaf adolescent girls in the special schools for the deaf in Ghana. The goal was to obtain data that could be used to improve menstrual hygiene practices among the target population, and, to bridge the gap in the existing literature regarding menstrual hygiene management experiences of in-school adolescent deaf girls in Ghana.
Method
This study adopted a mixed method approach to investigate the menstrual hygiene management challenges of in-school deaf adolescent girls in Ghana. A total of 152 participants comprising 118 schoolgirls, 15 boys, seven school heads, six teachers, and six school housemothers from seven special schools were involved in the study. Since the students were living in a boarding house or a residential school setting, in accordance with the ethical principles of the Ghana Education Service, informed consent was sought from the Special Education Division of the Ghana Education Service and the management of the schools.
Results
The findings identified five challenges facing the girls. These are inadequate access to sanitary pads, inappropriate school Water, Sanitation, and Hygiene (WASH) facilities, health related problems, negative attitude of male colleagues, and academic related challenges.
Conclusion
The findings indicate that the quality of WASH facilities in the schools require improvement. We recommend that access to sanitary kits for underprivileged girls in the schools should be made a priority issue of the school hygiene programme of the Ghana Education Service, boys and male teachers should be included in all menstrual hygiene management awareness programs, whiles the capacity of school housemothers on menstrual hygiene management should be enhanced.
Influence of perception on service satisfaction of community health centers among older adults or their families in Chongqing, China: a path analysis
Authors: Luo Jing , Sha Zhihui , Wu Tiantian , Liu Chen , Wang Chenghu , Luo Jing 
Published: June 2022

Abstract
Background
Community health centers (CHCs) have now served as the primary healthcare facilities especially for older adults in China. There is a paucity in current literature about public satisfaction with CHC services from the perspective of subjective perception. We aimed to identify the perception factors influencing satisfaction with CHC services among older adults or their families, and explore the influence paths, in Banan district of Chongqing, China.
Methods
A sample survey was conducted among 879 households in 32 communities in Banan district in March 2019 to obtain the basic data. The hypothetical service satisfaction model, the degree of the influence of each perception factor on final satisfaction, and influence paths were analyzed using the Smart PLS 3.0 software.
Results
A total of 800 households with older adult(s) aged 60 years and over were included in the study. Service expectation (-0.191), perceived quality (0.508) and perceived value (0.441) were the three direct factors influencing the satisfaction with CHC services. Both perceived quality and service expectation could indirectly affect public satisfaction by way of influencing perceived value (0.224 and -0.087, respectively).
Conclusions
Service expectation, service quality and value recognition are the main factors affecting satisfaction with CHC services. Service quality and accessibility should be improved along with the incremental construction of rational service expectation towards CHCs. Policy and financial inputs and the introduction of well-trained health providers are of great importance. Furthermore, equal access to CHC services should be gradually promoted especially for older adults.

Published: June 2022

The objective: to study prevalence and evaluate the eﬃcacy of therapy and prevention of nonspeciﬁc urinary tract infection (NUTI) in tuberculosis patients as well as the possibility of combining them with anti-tuberculosis therapy.Subjects and Methods. 936 patients with various localizations of tuberculosis at the age from 18 to 96 years old were examined. Men made 447 (47.8%), and women – 489 (52.2%). NUTI was diagnosed based on the following criteria: the presence of typical symptoms, leukocyturia and bacteriuria detected by urine microscopy, positive results of urine culture for nonspeciﬁc bacterial population, and negative urine tests for tuberculous mycobacteria.Results. The prevalence of NUTI among tuberculosis patients made 174 (18.6%) out of 936 patients, it was found among all forms of TB but most frequently in urogenital tuberculosis (74.1%). Prophylactic treatment tactic (antibacterial therapy and the herbal formulation of Kanefron N) was oﬀered. Treatment eﬃcacy made 94.6%, while patients received anti-tuberculosis therapy, and the combination of drugs caused no adverse reaction in any patient. When choosing a therapeutic tactic, it is necessary to take into account the presence of structural and functional changes in the urinary tract which reduce treatment eﬃcacy.
Effect of large scale roughness of block ramps on dissolved oxygen efficiency in water
Authors: Esmaeili Varaki Mahdi , Kamakoli Masomeh , Biabani Roya , Navabian Maryam 
Published: June 2022

Abstract
Block ramps are generally characterized by super critical flow over the ramps, and the presence of roughness lying on the surface of the block ramps induces excessive turbulence, which causes some turbulent energy dissipation and air entrainment. Aeration in a block ramp is caused by the intensity of turbulence created in the water flow by surface roughness of the block ramp and hydraulic jump downstream of block ramp. Macro or large-scale roughness like boulders, as a protruding element on surface of block ramp, could increase intensify turbulence and flow aeration along block ramps. This paper presents an experimental investigation of the dissolved oxygen efficiency in block ramps with slopes of 1:3, 1:5 and 1:7, on which large-scale granular materials with different arrangement patterns were glued. Comparison of results indicated that, for both free and ramp hydraulic jumps, the block ramps with a slope of 1:3 and large-scale roughness increase the dissolved oxygen efficiency almost 20% above that of the similar smooth block ramps. By reducing of the slope of block ramps to 1:5, the dissolved oxygen efficiency of the block ramps with large surface roughness became 3 and 19% for free and ramp hydraulic jumps, respectively. However, the block ramps with 1:7 slope had corresponding dissolved oxygen efficiency of 19 and 32%, respectively. Furthermore, installation of large scale roughness with the structured arrangement have better performance to increase dissolved oxygen (DO) in comparison with the interlocked large-scale roughness.
Experimental study of cavitation index in an ogee spillway by considering convergence angle of sidewalls
Authors: Foroudi Ali , Barati Reza 
Published: June 2022

Abstract
Cavitation is among the most complex and common damage occurring in spillway structures, which is one of the most expensive parts of a dam. The cavitation index, as the one of the most efficient approaches, can be used to analyze this important hydraulic phenomenon. The present study examines the changes in the cavitation index caused by changes in the convergence angle of an ogee spillway's sidewalls with an arc in the plan. To this end, a spillway was constructed on the 1:50 scale. Then, it was tested with four different convergence angles, including 0°, 60°, 90°, and 120°, relative to the spillway's sidewalls and six different flow rates per unit width ranging from 6.74 to 48.42 (l/s)/m. The results indicated that as the flow rate increased, the cavitation index relatively declined at both crest and chute of the spillway while growing at its toe. It was observed that the lowest cavitation index was found to be 1.54 in.X/Hd = 2.42 at an angle of 0° and a flow rate per unit width of 40.52 (L/s)/m.

Authors: Devi Geeta , Kumar Munendra 
Published: June 2022

Abstract
The scour around the bridge piers has been estimated using conventional empirical formulae; however, these formulae are unable to predict the scour depth precisely. The present study is conducted in two parts (a) experimental investigation for evaluating the behaviour of local scour around twin piers positioned in the transverse direction of flow and (b) an empirical equation to estimating scour depth is proposed utilising new evolutionary artificial intelligence technique gene expression programming (GEP). Experimental results for the present study demonstrate the influence of the rate of flow and clear spacing between the piers on the scour depth. Additionally the results of the soft computing technique GEP during testing and training of proposed modelling, fitness function root mean square error is observed as 0.00133 and 0.00113, with the coefficient of determination as 0.950 and 0.955, respectively. Furthermore, in order to find out the role of each variable for scour depth sensitivity, analysis has been conducted. The findings of the sensitivity analysis show that the pier spacing and rate of flow play the most significant role in scour depth estimation. Results of this study demonstrate a good agreement with the proposed GEP model and conclude that it is a better approach for forecasting scour depth.
Investigation of nitrite accumulation by hydrogenotrophic denitrification in a moving bed biofilm reactor for partial denitrification and anammox process

Published: June 2022

Abstract
The partial denitrification and anammox (PDA) process has received attention for its ability to optimize treatment of wastewater containing a low -N concentration. This study investigated the suitable operational conditions for -N accumulation by hydrogenotrophic denitrification (HD) in operation of a laboratory-scale moving bed biofilm reactor, for future application in the PDA process. -N accumulation was achieved by minimizing the H2 flow rate under optimized conditions (i.e., 15 mL/min H2 flow rate, 40 mg-N/L influent -N, 7.0 h hydraulic retention time, and 2 L working volume). Hydrogenophaga comprised 39.2% of the bacterial abundance after -N accumulated, indicating its contribution to the -N accumulation. In addition, an intermittent H2 supply maintained the -N accumulation rate (NAR) and maximized the nitrite accumulation efficiency (NAE). A H2 supply ratio of 0.7 (i.e., ON: 7 min, OFF: 3 min) was optimal, which induced increases in NAR, NAE, and the -N removal efficiency that reached 0.07±0.01 kg-N/m3/d, 64.4±14.5%, and 89.2±8.9%, respectively. The ratio of H2 supply rate to the -N loading rate was calculated as 4.3 in this experiment, which may represent the optimal balance for maximization of -N accumulation by HD.
Online Partner Seeking and Sexual Behaviors Among Men Who Have Sex With Men From Small and Midsized Towns: Cross-sectional Study
Authors: Pravosud Vira , Ballard April M , Holloway Ian W , Young April M 
Published: June 2022

Background
Men who have sex with men (MSM) residing outside of large urban areas are underrepresented in research on online partner seeking and sexual behaviors related to transmission of HIV.

Objective
We aimed to determine associations between the use of the internet or social networking apps (online tools) to meet partners for sex, dating, or for both purposes (online partner seeking) and sexual behaviors among MSM residing in small and midsized towns in Kentucky, United States.

Methods
Using peer-referral sampling and online self-administered questionnaires, data were collected from 252 men, aged 18 to 34 years, who had recently (past 6 months) engaged in anal sex with another man and resided in Central Kentucky. Using multivariable logistic regression models, we assessed associations of online partner seeking and HIV-related sexual behaviors.

Results
Most (181/252, 71.8%) of the participants reported using online tools for partner seeking. Of these 181 respondents, 166 (91.7%) had used online tools to meet partners for sex (n=45, 27.1% for sex only; and n=121, 72.9% for sex and dating) and 136 (75.1%) had used online tools to meet partners for dating (n=15, 11% for dating only; and n=121, 89% for sex and dating). Adjusted analyses revealed that MSM who had engaged in condomless insertive and receptive anal intercourse were less likely to report online partner seeking (adjusted odds ratio [aOR] 0.22, 95% CI 0.07-0.68; P=.009 and aOR 0.25, 95% CI 0.10-0.66; P=.005, respectively). Increased number of insertive and receptive anal sex partners and substance use before or during sex were associated with higher odds of online partner seeking (aOR 1.31, 95% CI 1.11-1.55; P=.001; aOR 1.20, 95% CI 1.05-1.39; P=.008; and aOR 2.50, 95% CI 1.41-4.44; P=.002, respectively).

Conclusions
Among MSM who reside outside of large urban areas and practice online partner seeking, HIV risk-reduction interventions should address safer sex practices, including the risks for HIV transmission associated with alcohol or drug use before or during sex. MSM who do not practice online partner seeking are in need of continued outreach to reduce condomless anal sex.
Time-Varying Associations Between Device-Based and Ecological Momentary Assessment–Reported Sedentary Behaviors and the Concurrent Affective States Among Adolescents: Proof-of-Concept Study
Authors: Zink Jennifer , Yang Chih-Hsiang , Alves Jasmin M , McAlister Kelsey L , Huh Jimi , Pentz Mary Ann , Page Kathleen A , Dunton Genevieve F , Belcher Britni R 
Published: June 2022

Background
Previous studies on affective state–sedentary behavior (SB) associations have not accounted for their potentially time-varying nature and have used inconsistent SB measurement modalities. We investigated whether the strength of the associations between affective states and SB varied as a function of the time of day and by SB measurement modality (device-measured SB vs ecological momentary assessment–reported screen-based SB) in youth.

Objective
This study aimed to establish a proof of concept that SB–affective state associations may not be static during the day. In addition, we aimed to inform the methodology of future work, which may need to model associations as functions of the time of day and carefully consider how SB is operationalized or measured.

Methods
A total of 15 adolescents (age: mean 13.07, SD 1.03 years; 10/15, 67% female; 6/15, 40% Hispanic; 10/15, 67% healthy weight) wore thigh-mounted activPAL accelerometers and simultaneously reported their screen-based SBs and concurrent positive and negative affective states via ecological momentary assessment for 7 to 14 days (N=636 occasions). Time-varying effect models (varying slopes) examined how each measure of SB was associated with concurrent affective states from 7 AM to 8 PM.

Results
Time-varying effect model plots revealed that these associations varied in strength throughout the day. Specifically, device-based SB was related to greater concurrent negative affect only after approximately 5 PM and was unrelated to concurrent positive affect. Screen-based SB was related to greater concurrent negative affect only from 7 AM to approximately 9 AM. This was also related to greater concurrent positive affect from 7 AM to approximately 9:30 AM and from approximately 3 PM to approximately 7 PM.

Conclusions
We provide preliminary evidence to suggest that future confirmatory studies investigating the SB–affective state relationship should consider the time-varying nature of these associations and SB measurement modality. There may be critical time windows when specific types of SBs co-occur with affect, suggesting that interventions may need tailoring to the time of day and type of SB if future studies using similar methodologies can replicate our findings.
Exploiting Intersentence Information for Better Question-Driven Abstractive Summarization: Algorithm Development and Validation
Authors: Wang Xin , Wang Jian , Xu Bo , Lin Hongfei , Zhang Bo , Yang Zhihao 
Published: June 2022

Background
Question-driven summarization has become a practical and accurate approach to summarizing the source document. The generated summary should be concise and consistent with the concerned question, and thus, it could be regarded as the answer to the nonfactoid question. Existing methods do not fully exploit question information over documents and dependencies across sentences. Besides, most existing summarization evaluation tools like recall-oriented understudy for gisting evaluation (ROUGE) calculate N-gram overlaps between the generated summary and the reference summary while neglecting the factual consistency problem.

Objective
This paper proposes a novel question-driven abstractive summarization model based on transformer, including a two-step attention mechanism and an overall integration mechanism, which can generate concise and consistent summaries for nonfactoid question answering.

Methods
Specifically, the two-step attention mechanism is proposed to exploit the mutual information both of question to context and sentence over other sentences. We further introduced an overall integration mechanism and a novel pointer network for information integration. We conducted a question-answering task to evaluate the factual consistency between the generated summary and the reference summary.

Results
The experimental results of question-driven summarization on the PubMedQA data set showed that our model achieved ROUGE-1, ROUGE-2, and ROUGE-L measures of 36.01, 15.59, and 30.22, respectively, which is superior to the state-of-the-art methods with a gain of 0.79 (absolute) in the ROUGE-2 score. The question-answering task demonstrates that the generated summaries of our model have better factual constancy. Our method achieved 94.2% accuracy and a 77.57% F1 score.

Conclusions
Our proposed question-driven summarization model effectively exploits the mutual information among the question, document, and summary to generate concise and consistent summaries.
