Abstract
Metal-organic framework (MOF) nanomaterials are emerging porous coordinative polymers with large surface area and high porosity. Their application scenarios highly depend on adsorption/desorption dynamics of guest molecules in the framework. For representative ZIF-8 with framework flexibility, the study of molecule transportation in the pore channels of ZIF-8 will address the ambiguity of unclear application scenarios. In this study, the integration of lab-on-fiber technology and nanotechnology are demonstrated for real-time monitoring of adsorption/desorption dynamics of heterocyclic volatile compounds (VOCs) with kinetic diameters larger than the window aperture of ZIF-8. The in-line fiber interferometer with cascaded long-period gratings is used to monitor the real-time refractive index change of VOC adsorption/desorption. The structure-effect relationship between guest VOCs and framework flexibility is analyzed. It shows that the adsorption dynamics is highly related to the molecular geometry and kinetic diameter. The framework flexibility results in the trapping of guest VOCs toluene, pyridine, and tetrahydrofuran in the frameworks. The methanol adsorption/desorption is an effective strategy for the fast desorption of trapped residual VOCs in the framework. Finally, we conceptually demonstrated the real-time monitoring of trace toluene enrichment using ZIF-8 for indoor air purification. This study paves the way for the in-depth understanding of framework flexibility for MOF’s application.

Abstract
This study aimed to analyze the effect of tuck and miss stitch structures of regenerated cellulose fabrics like viscose, modal, Tencel, and bamboo. The fabrics were developed with the same stitch length and tightness factor and analyzed for their geometrical properties after dry and wet relaxation. The study results revealed that wet relaxation treatment showed more significant changes in the geometrical constant values (K) than the dry relaxation process. The highest wale density change was noted with cross miss stitch fabric and a maximum course density change noted for cross tuck samples after dry and wet relaxation. The differences in wale and course density were noted as statistically insignificant for the aforementioned structure after dry and wet relaxation (p &gt; 0.05). However, in the case of stitch density, there is a statistical significance noted for the tested samples (p &lt; 0.05). The maximum changes were noted in plain fabric followed by twill structure. The loop shape factor (Kr) value suggests higher distortion in the cross tuck fabric and after wet relaxation over dry relaxed samples followed by plain, twill, and miss stitch structures, and we also noted the relaxation process did not alter the loop shape factor (Kr) significantly between the dry and wet process (p &gt; 0.05).

Abstract
A simple HPLC-UV procedure is described in our paper which is suitable for the rapid and cost-efficient determination of prochloraz in mushrooms. Prochloraz is the only fungicide in EU which use is allowed in mushroom production. The aim of our work was the development of a simple method that is suitable for the control of this pesticide in everyday analyses during mushroom production. The procedure involves a simple sample preparation method based on solid-liquid extraction (modified QuEChERS extraction method EN 15662) followed by an HPLC-UV determination (recovery: 97–99%; limit of detection LOD: 0.01 mg/kg; limit of quantification LOQ: 0.05 mg/kg).
Social-networks-related stimuli interferes decision making under ambiguity: Interactions with cue-induced craving and problematic social-networks use

Published: July 2021

AbstractBackground and aimsSocial-networks-use disorder is discussed as a potential further type of disorders due to addictive behaviors. Theoretical models assume cue-induced craving and disadvantageous decision making to be relevant mechanisms. This study investigates if the presentation of social-networks-related cues interferes with decision making under ambiguity.MethodsCraving was induced with a cue-reactivity paradigm and assessed with a visual analogue scale. Participants (N = 146) played a modified Iowa Gambling Task with social-networks-related cues and neutral cues presented on the advantageous and disadvantageous decks respectively, or vice versa. Symptoms of social-networks-use disorder were measured with a modified version of the short Internet Addiction Test.ResultsOverall, participants chose options with neutral cues more often than those with social-networks-related cues, even if it was disadvantageous. There was a significant interaction between decision-making performance and Iowa Gambling Task condition in predicting symptom severity. The results indicate that choosing decks with social-networks-related cues even if it was disadvantageous is associated with higher tendencies towards a social-networks-use disorder. The interaction with cue-induced craving did not explain further variance.Discussion and ConclusionsThe results highlight the relevance of cue reactivity, decision making, and their interaction as potential mechanisms explaining tendencies towards a social-networks-use disorder. Decision making was influenced by affective responses, which could result in a higher risk of a potential addictive behavior. This is consistent with the findings from addiction research and with theoretical approaches assuming an imbalance between affective and cognitive processes in addictive behaviors.

Knowledge, Attitude, and Practice towards Dengue: A Study among the Inhabitants of Malibagh of Dhaka city, Bangladesh
Authors: Sharmila Nowshin , Habib Shah Ehsan 
Published: July 2021

Background: Dengue remains a major public health challenge causing death among many people in Bangladesh. The magnitude of dengue-related illness and death has significantly increased over recent years. Study was conducted to assess the level of knowledge, attitudes, and practices related to Dengue fever.
Methods: A cross-sectional study was conducted among a total of 193 males and females who consented to participate in the study. Respondents were included purposively from selected areas in Malibagh an area classified as a stable dengue-prone region of the capital city. The survey was carried out by face-to-face interview using a pre-tested standardized and structured questionnaire.
Results: The results reveal that dengue infection occurred in 20.2% of residents. Only 27.5% had a good knowledge score (8 out of 11 items), and 83.9% had a positive attitude, while 34.2% had a good compliance practice. Knowledge was significantly associated with education, income, and age (p < 0.05). Misconceptions existed about the transmission of dengue – more than one-third (36.8%) reported that the Aedes aegypti mosquito could only breed in clean water, and 32.1% were aware of the biting time of the mosquito. Most participants (55.4%) strongly agreed that dengue is a serious illness, and over half (65.3%) reported that it could be prevented with coverage of vector control interventions. The majority (64.2%) used mosquito nets as a preventive measure, while over one-third (35.2%) reported they discarded waste, containers, and non-used bottles across their yards that hold water. Although the respondents had quite positive attitude of preventive measures regarding dengue (83.9%), a sizeable number (34.2%) did not put this attitude into practice.
Conclusion: Poorly planned urbanization combined with an explosive urban population in the capital city has brought the mosquito and the human host into close proximity. The government should launch health education programs on dengue prevention to educate the community members, addressing misconceptions about their preventive measures and on how they could eliminate the risk factors related to practices.

Published: July 2021

Background: In in vitro culture systems IGF-I was known to promote follicular maturation, granulosa cell proliferation and increase overall cellular function. The expression patterns of developmentally important markers for IGF-I are expressed differentially during the transition of preantral follicles to the ovulatory stage. Therefore, we aimed to investigate the influence of time specific addition of Insulin like growth factor-I (IGF-I) on in vitro development of sheep preantral follicles (PFs’). Methods: Mechanically isolated sheep preantral follicles were cultured for six days either in TCM 199B or standard medium supplemented with IGF-I at different points during the culture period and were subsequently subjected to in vitro maturation (IVM) for additional 24hrs to evaluate different follicular development parameters. Conclusion: Based on the results, it is concluded that: 1) IGF-I supplementation was needed during early rather than later stages of culture period, therefore, role of IGF-I in time/stage specific manner in cultured preantral follicles is confirmed. 2) Supplementation of TCM 199B with IGF-I simultaneously for the first two days followed by TCM 199B alone without any growth factor (s) in later days (Treatment 1) supported better development of PFs’ in vitro.

EVENT-CANCELLING SEMANTICS OF THE ENGLISH ASPECTUALIZER START AND ITS SERBIAN EQUIVALENT KRENUTI
Authors: Milivojević Nataša 
Published: July 2021

The paper revisits the issue of semantic equivalency of two aspectual verbs, start and krenuti, which is proposed by xxx (2021a, 2021b). The present analysis focuses on the causative and dynamic semantic features of start and krenuti, with the aim of a contrastive analysis of the aspectual constructions headed by these two verbs. It is shown that both start and krenuti, provided that the necessary linguistic conditions are met, have the ability to “cancel” the event initiated via constructional phase modification. The conditions for such event-cancelling result from the lexical semantics of start and krenuti, as well as from the semantic co-composition on the level of the aspectual construction as a whole. The theoretical frame of the analysis is the presupposition and consequence account by A. Freed (1979). The contrastive analysis and presented theoretical conclusions are backed by a parallel corpus of 200 English and Serbian sentences compiled from the Corpus of Global Web-Based English (GlowBE 2013) and the Corpus of Contemporary Serbian Language (SrpKor 2013).

Published: July 2021

Abstract
Objective Ethiopia is one of the countries with high endemicity of hepatitis B infection. In Ethiopia, the current vaccine coverage among health care workers accounts for around 14%. Most health workforce (241,250) of Ethiopia was first considered as susceptible with a probability of getting Hepatitis B Virus acutely and 5–10% chance of progressing to chronic Hepatitis B. Hence, examining cost-utility analysis of hepatitis B vaccination coverage among healthcare workers in Ethiopia was found the most essential work.Method Markov model for expanding vaccination coverage (3 doses of hepatitis B vaccine) was simulated based on the data obtained both primary and secondary data. A secondary data particularly cost and effectiveness data were obtained from published articles, World Health Organization (WHO) guidelines and Ethiopian Federal Ministry of Health (FMOH) documents. Moreover, cost related data for vaccination and chronic hepatitis B treatment were also gathered by interviewing expertise from Tikur Anbesa Specialized Hospital (TASH). This study was conducted from a healthcare payer perspective, with 3% discount rate of cost and health outcome as WHO recommendation. Primarily health outcome was measured by Quality Adjusted Life Year (QALY) gain and Incremental Cost-Effectiveness Ratio (ICER). Deterministic analysis and tornado diagrams were employed to manage parameter uncertainty and show a plausible range of cost and effectiveness of variables.Result Current vaccination program is more expensive (USD 29.99) with a positive incremental cost of USD 1.32 and less effective that have negative incremental effectiveness of -0.08 and total life year gains of 28.54 than Expanded Hepatitis B vaccination strategy which costs USD 28.67 and gives relatively high total life-year gain of 28.62. The resulting ICER was USD 16.23 per QALY gained. However, the ICER was a negative for the current vaccination strategy that could show, it was dominated by the Expanded Hepatitis B vaccination strategy. One-way sensitivity analysis also provided that the current vaccine coverage was dominated for an increase in the risk of infection among unvaccinated individuals.Conclusion Increasing current vaccine coverage from 14% to no less than 80% across Ethiopian healthcare workforces would be the most cost-effective strategy.

Abstract
Monitoring temporal variation of streamflow is necessary for many water resources management plans, yet, such practices are constrained by the absence or paucity of data in many rivers around the world. Using a permanent river in the north of Iran as a test site, a machine learning framework was proposed to model the streamflow data in the three periods of growing seasons based on tree-rings and vessel features of the Zelkova carpinifolia species. First, full-disc samples were taken from 30 trees near the river, and the samples went through preprocessing, cross-dating, standardization, and time series analysis. Two machine learning algorithms, namely random forest (RF) and extreme gradient boosting (XGB), were used to model the relationships between dendrochronology variables (tree-rings and vessel features in the three periods of growing seasons) and the corresponding streamflow rates. The performance of each model was evaluated using statistical coefficients (coefficient of determination (R-squared), Nash-Sutcliffe efficiency (NSE), and root-mean-square error (NRMSE)). Findings demonstrate that consideration should be given to the XGB model in streamflow modeling given its apparent enhanced performance (R-squared: 0.87; NSE: 0.81; and NRMSE: 0.43) over the RF model (R-squared: 0.82; NSE: 0.71; and NRMSE: 0.52). Further, the results showed that the models perform better in modeling the normal and low flows compared to extremely high flows. Finally, the tested models were used to reconstruct the temporal streamflow during the past decades (1970–1981).

Published: July 2021

Abstract
Metaheuristic algorithms such as simulated annealing (SA) has been implemented for optimization in combinatorial problems, especially for discreet problems. SA employs a stochastic search, where high-energy transitions (“hill-climbing”) are allowed with a temperature-dependent probability to escape local optima. Ising spin glass systems have properties such as spin disorder and “frustration” and provide a discreet combinatorial problem with high number of metastable states and ground-state degeneracy. In this work, we exploit subthreshold Boltzmann transport in complementary two-dimensional (2D) field effect transistors (p-type WSe2 and n-type MoS2) integrated with analog, non-volatile, and programmable floating-gate memory stack to develop in-memory computing primitives necessary for energy and area efficient hardware acceleration of SA for the Ising spin systems. We experimentally demonstrate > 800X search acceleration for 4×4 ferromagnetic, antiferromagnetic, and a spin glass system using SA compared to an exhaustive search using brute force trial at miniscule total energy expenditure of ~120 nJ. Our hardware realistic numerical simulations further highlight the astounding benefits of SA in accelerating the search for larger spin lattices.

Abstract
BackgroundMetabolomics is a promising approach that can be used to understand pathophysiological pathways of Alzheimer disease (AD). However, the relationships between metabolism and AD are poorly understood. The aim of this study is to investigate the causal association between circulating metabolites and risk of AD by combining metabolomics with genomics through two-sample Mendelian randomization (MR) approach.MethodsGenetic associations with 123 circulating metabolic traits were utilized as exposures. A large summary statistics data from International Genomics of Alzheimer’s Project was used in primary analysis, including 21,982 AD cases and 41,944 controls. Validation was further performed using family history of AD data from UK Biobank (27,696 cases of maternal AD, 14,338 cases of paternal AD and 272,244 controls). We utilized the inverse-variance weighted method as primary analysis and four additional MR methods (MR-Egger, weighted median, weighted mode, and MR pleiotropy residual sum and outlier) for sensitivity analyses.ResultsWe found one-fold increased risk of developing AD per standard deviation increase in the levels of circulating ApoB (odd ratio (OR)=3.18; 95% confidence interval (CI): 1.52–6.66, P=0.0022) and glycoprotein acetyls (OR=1.21; 95% CI: 1.05–1.39, P=0.0093), serum total cholesterol (OR=2.73; 95% CI: 1.41-5.30, P=0.0030), and low-density lipoprotein (LDL) cholesterol (OR=2.34; 95% CI: 1.53-3.57, P=0.0001). Whereas glutamine (OR=0.81; 95% CI: 0.71-0.92, P=0.0011) were significantly associated with lower risk of AD. We also detected causal effects of several different composition of LDL fractions on increased AD risk, which has been verified in validation. However, we found no association between circulating high-density lipoprotein cholesterol and AD.ConclusionsOur findings provided robust evidence supporting causal effects of circulating glycoprotein acetyls, ApoB, LDL cholesterol, and serum total cholesterol on higher risk of AD, whereas glutamine showed the protective effect. Further research is required to decipher the biological pathways underpinning associations.
Retroperitoneal Mass: Lymphoma as Differential Diagnosis To Retroperitoneal Fibrosis. Case Report.
Authors: Nussberger Madalina , Kim Olaf , Cogliatti Sergio , Neumann Thomas 
Published: July 2021

Abstract
Background The nature of a solid retroperitoneal mass can either be autoimmune or neoplastic and should be investigated by imaging and histology. The spectrum of differential diagnoses includes primarily retroperitoneal fibrosis and retroperitoneal tumors. Because treatments of retroperitoneal fibrosis and retroperitoneal tumors vary substantially, accurate and early diagnosis is highly relevant. Case presentation We present a case of a fifty-four-year old woman that was admitted to our hospital with stroke like symptoms. Suspecting a vasculitis, magnet resonance imaging of the head and abdomen were done, which revealed a circular enhancement of a cranial vessel as well as retroperitoneal and peri-aortic masses. Concerning this specific radiographic patterns, an autoimmune process like retroperitoneal fibrosis was hypothesized. Steroid treatment did not lead to significant remission though. On re-evaluation of the mass because of refractory disease, fine needle aspiration did not show malignant cells while surgery and histologic assessment revealed neoplastic lymphoproliferation. The final diagnosis was a non- Hodgkin B- Cell Lymphoma. Chemo- and Immunotherapy was initiated. A control abdominal computer tomography was performed which revealed a significant remission of the retroperitoneal mass. Conclusion Initially, the retroperitoneal mass was highly suspicious for RF. The results of imaging can be useful, however, histology should always be taken into consideration when there is an uncertain clinical presentation. Without histology we would have missed a non-Hodgkin B-Cell Lymphoma in this case. Minimal invasive techniques like fine needle aspiration may be practical but can demonstrate false negative results.
