Fish Injury and Mortality During Passage Through Pumping Stations

An unwanted side effect of pumping stations is that fish suffer from injury and mortality when passing through the pumps and that fish migration is hampered. In recent years, the development of so-called fish-friendly pumping stations has received increasing attention from European governmental institutions and pump manufacturers. In the Netherlands, many field studies have been conducted over the last decade to assess the chances of survival for fish passing through pumps. A clear correlation between observed injury or mortality and, for example, flow rate, shaft speed, or pump type could not be established. This paper presents a new analysis of these field studies. It uses American studies on the biological criteria for fish injury, the most important of which are pressure changes, shear forces, and mechanical injury. A blade strike model is adapted to fish passing through centrifugal pumps of radial, mixed-flow, and axial type. It reveals the relation between fish injury and the type of pump, its size, shaft speed, and pressure head. The results correlate fairly well with experiments. The flow through a typical mixed-flow pump is calculated using computational fluid dynamics (CFD). The results show that pressure fluctuations and shear forces are not likely to add much to fish mortality. Guidelines for the design and selection of fish-friendly pumps are given with the introduction of two new dimensionless numbers: the blade strike probability factor and the blade strike velocity factor. It shows that fish-friendliness of pumps decreases with increasing specific speed value.

Purpose One of the hospital management issues that has not been studied much during the COVID-19 Pandemic is the relationship between health workers’ performance, job satisfaction and remuneration. This study aims to examine the relationship between remuneration, job satisfaction and the employee performance during 2019–2021. Materials and Methods This study applied an employee satisfaction survey at a General Academic Hospital between 2019–2021. The population and samples were 716 employees. The data collection were based on the personnel database, remuneration database, and the annual Employee Satisfaction Survey Database for the period 2019–2021 at General Academic Hospital of Dr. Soetomo, Surabaya, Indonesia. Results The results of the correlation test between Employee Satisfaction, Remuneration, and Performance based on employee performance objectives showed an insignificant positive correlation between the remuneration variable and satisfaction based on The Job Itself; very weak significant positive correlation between remuneration variable and Satisfaction based on Pay; a very weak significant positive correlation between the remuneration variable and Satisfaction based on Promotion; very weak significant positive correlation between remuneration variable and satisfaction based on supervision; significant positive correlation between remuneration variable and satisfaction based on coworkers; There is a significant positive correlation between remuneration and performance variables. Conclusion The correlation between remuneration and employee satisfaction based on the Job Description Index shows that the components of the job itself, and coworkers have a positive but not significant relationship, while the components of pay, promotion, and supervision have a positive and significant relationship. Employees satisfaction with performance achievement have a positive and significant relationship, especially job satisfaction based on pay and supervision, but there is also a positive and insignificant relationship related to job satisfaction based on the job itself, promotion, and co-workers.
Topology-Based Machine Learning: Predicting Power Line Communication Quality in Smart Grids

Smart Grids (SG) envision the exchange of both power and data, enabling system and customers to generate and transfer energy in a more efficient and balanced way. Among the relevant communication technologies, we find Power-Line Communications (PLC), which allow for data transmission on the electrical cables used for power delivery. Despite the hostile medium, PLC offer reliability and data rates to support exchange of control traffic, smart metering and sensor network applications. The distribution portion of the power delivery network, which we focus on in this work, is topologically complex, which makes channel prediction complicated. We show how random realistic topologies can be generated and then used to train a Machine Learning (ML) algorithm to infer PLC link quality (based on channel response) exploiting solely topology descriptors. We eventually show how precisely the communication quality can be inferred from the SG topology through ML. In doing so, we also discuss how the ML approach offers the common ground between top-down and bottom-up approaches for network characterization and how it enables smart decision making in the SG.
Emotional Intelligence and School Bullying Victimization in Children and Youth Students: A Meta-Analysis

School victimization among children and youth is a global public health issue that has long-term adverse effects on the victims’ mental health and behavioral development. Theories and research suggest that emotional intelligence may operate as a buffer against school bullying victimization. However, the strength of the association between emotional intelligence and bullying victimization is controversial. Therefore, we aimed to conduct a meta-analysis to evaluate the exact association between Emotional intelligence and school bullying victimization. We conducted a systematic search in PubMed, Web of Science, ProQuest Dissertations, Google Scholar, and China National Knowledge Infrastructure (CNKI) from inception to March 2022 for relevant studies that examine the association between emotional intelligence and school bullying victimization without a language limit. Twenty-four articles were included in our meta-analysis (n = 27,438). There was a small, negative, and significant association between emotional intelligence and school victimization among children and youth students. Sex and emotional intelligence measurement tools were variables that significantly moderated the link between emotional intelligence and bullying victimization. The findings indicated that improving students’ emotional intelligence could be a crucial strategy to lower the students’ risk of being bullied in school and online. It would be more effective among male students.
Nonequilibrium many body theory for quantum transport in terahertz quantum cascade lasers

This paper presents a predictive Keldysh nonequilibrium many body Green’s functions theory for quantum transport including high order electron-electron, electron-phonon, electron-impurity, and interface roughness scattering processes. Our approach is fully frequency and momentum dependent including nondiagonal dephasing terms in both frequency and k-space. A detailed balance between coherent and scattering processes leads to local current conservation even if a small number of states is considered. Good agreement with experiments is obtained for a terahertz quantum cascade laser.
On viscous beads flowing down a vertical fibre

The vertical flow of a fluid, under the influence of gravity, down the exterior of a rigid fibre is a flow accompanied by rich dynamics manifested via the formation of droplets, or beads, driven by a Rayleigh mechanism modulated by the presence of gravity. These droplets propagate down the fibre and undergo coalescence with preceding droplets. Different flow regimes are possible depending on system parameters such as the fibre radius, liquid flow rate and physical properties. We derive an evolution equation for the interface in the long-wavelength approximation, which captures the flow characteristics of the system; this model is similar to those previously used to investigate the dynamics of slender viscous threads in the absence of the fibre. Analytical and numerical solutions of the evolution equation yield information regarding the shape and propagation speeds of the droplets, which is in good agreement with available experimental data as well as those obtained as part of the present work. Connections with models already available in the literature are also established.
Non-standard neutrino interactions in IceCube

Neutrinos interact weakly with matter mediated by the W and Z bosons. For example, neutrino interactions with electrons in the earth interferes with the propagation of neutrinos, producing a measurable effect called the “MSW effect” [2]. These types of interactions are the “standard interactions” of neutrinos in standard matter. Some non-standard model theories predict the existence of heavy TeV-scale bosons. Recent ATLAS results have 3.4 sigma significance for a resonance in the diboson channel around 2 TeV [1], which could be caused by non-standard bosons interacting with matter. The neutrino interaction rate in matter would then fluctuate from the standard prediction due to interactions with these bosons in addition to the standard W and Z. Like the MSW effect, the fluctuation of neutrinos detected compared to those produced on the opposite side of the earth would be measurable. This analysis aims to measure this effect in the IceCube experiment using the event selection from the DeepCore three-year muon disappearance result. Because of the wide range of neutrino energies it can observe IceCube has the potential to set world leading limits for this measurement. The limits that can be set on the NSI parameters from interactions of muon neutrinos with non-standard bosons will be discussed.
Challenges with Online Teaching and Learning of English Vocabulary

This article aims to examine the challenges facing secondary school teachers and students in English vocabulary online classes in Amman, Jordan. It also aims to propose the most effective ways to overcome the encountered challenges. To this end, qualitative semi-structured interviews were conducted with thirty teachers and twenty students to understand their experiences related to the online learningteaching process. Based on these interviews, several challenges that might obstruct this process were identified, with some of the challenges reported by teachers being similar to those reported by students. Teaching and learning challenges included poor class management, poor Internet connection, and large class sizes. Moreover, the findings of this study highlighted that one of the most important challenges that teachers encountered in teaching English vocabulary online was the impossibility of using realia. The study concludes with some solutions from both teachers and students to overcome these difficulties, such as using more advanced online platforms, e.g., Google Meet, World Word, and Microsoft Teams, as well as splitting students into small online rooms, and using games/plays.
Menopause Is Associated with Obstructive Sleep Apnea in a Population-Based Sample from Mecklenburg–Western Pomerania, Germany

Objective: Menopause is associated with multiple health risks. In several studies, a higher incidence or a higher risk for obstructive sleep apnea (OSA) in post-menopausal than pre-menopausal women is reported. This study was designed to verify such a connection between menopause and OSA in a population-based sample. Methods: For a subsample (N = 1209) of the Study of Health in Pomerania (N = 4420), complete polysomnography data was available. Of these, 559 females completed a structured interview about their menstrual cycle. Splines and ordinal regression analysis were used to analyze the resulting data. Results: In the ordinal regression analysis, a significant association between the apnea–hypopnea index (AHI) and menopause indicated that post-menopausal women had a substantially higher risk of OSA. In accordance with previous studies, risk indicators such as body mass index (BMI), age, and the influence of hysterectomies or total oophorectomies were included in the model. Conclusions: Our results clearly confirmed the assumed connection between menopause and OSA. This is important because OSA is most often associated with male patients, and it warrants further research into the underlying mechanisms.
Multiple changepoints problem-nonparmetric procedures for estimation of the points of change

In this paper we consider several procedures for estimating the sites of multiple changepoints in the distribution of a sequence of independent, continuous observations. Each of these estimation schemes is based on the statistic proposed by Schechtman (1982) for testing hypotheses about a single change-point, in conjunction with a variety of techniques for detecting local maxima in a sequence of data. The results of an extensive Monte Carlo investigation are presented and used to provide guidelines for selecting a particular estimation procedure for a specific application.
A deep learning model to detect foggy images for vision enhancement

ABSTRACT Fog limits meteorological visibility, posing a significant danger to road safety. Poor visibility is considered as a significant contributor to road accidents in foggy weather conditions. Regardless, image defogging techniques can only work with foggy images. In a real-time system, however, defogging foggy images becomes difficult if they are not identified as foggy or clear. Because we cannot rely on human vision to distinguish between foggy and clear pictures, we need a robust model that classifies the input image as foggy or clear based on some features. This paper proposes a robust Deep Learning (DL) model based on Convolutional Neural Network (CNN) for classifying the input as foggy and clear. The proposed Deep Neural Network (DNN) architecture is efficient and precise enough to classify images as foggy or clear, with a training time complexity of and a prediction time complexity of . The experimental results reveal promising results in both qualitative and quantitative assessments. The model has an accuracy of 94.8%, precision of 91.8%, recall of 75.8% and F1 score of 80.3% when evaluated on the SOTS dataset, indicating that it might be utilized to mitigate the safety risk in vision enhancement systems.
A Singular Theta Lift and the Shimura Correspondence

Modular forms play a central and critical role in the study of modern number theory. These remarkable and beautiful functions have led to many spectacular results including, most famously, the proof of Fermat's Last Theorem. In this thesis we find connections between these enigmatic objects. In particular, we describe the construction and properties of a singular theta lift, closely related to the well known Shimura correspondence. We first define a (twisted) lift of harmonic weak Maass forms of weight 3/2-k, by integrating against a well chosen kernel Siegel theta function. Using this, we obtain a new class of automorphic objects in the upper-half plane of weight 2-2k for the group Gamma_{0}(N). We reveal these objects have intriguing singularities along a collection of geodesics. These singularities divide the upper-half plane into Weyl chambers with associated wall crossing formulas. We show our lift is harmonic away from the singularities and so is an example of a locally harmonic Maass form. We also find an explicit Fourier expansion. The Shimura/Shintani lifts provided very important correspondences between half-integral and even weight modular forms. Using a natural differential operator we link our lift to these. This connection then allows us to derive the properties of the Shimura lift. The nature of the singularities suggests we formulate all of these ideas as distributions and finally we consider the current equation encompassing them. This work provides extensions of the theta lifts considered by Borcherds (1998), Bruinier (2002), Bruinier and Funke (2004), Hovel (2012) and Bringmann, Kane and Viazovska (2013).
Ameliorative Effect of Posidonia oceanica on High Glucose-Related Stress in Human Hepatoma HepG2 Cells

Metabolic disorders characterized by elevated blood glucose levels are a recognized risk factor for hepatocellular carcinoma (HCC). Lipid dysregulation is critically involved in the HCC progression, regulating energy storage, metabolism, and cell signaling. There is a clear link between de novo lipogenesis in the liver and activation of the NF-κB pathway, which is involved in cancer metastasis via regulation of metalloproteinases MMP-2/9. As conventional therapies for HCC reach their limits, new effective and safe drugs need to be found for the prevention and/or adjuvant therapy of HCC. The marine plant Posidonia oceanica (L.) Delile is endemic to the Mediterranean and has traditionally been used to treat diabetes and other health disorders. The phenol-rich leaf extract of Posidonia oceanica (POE) is known to have cell-safe bioactivities. Here, high glucose (HG) conditions were used to study lipid accumulation and fatty acid synthase (FASN) expression in human HepG2 hepatoma cells using Oil Red O and Western blot assays. Under HG conditions, the activation status of MAPKs/NF-κB axis and MMP-2/9 activity were determined by Western blot and gelatin zymography assays. The potential ameliorative role of POE against HG-related stress in HepG2 cells was then investigated. POE reduced lipid accumulation and FASN expression with an impact on de novo lipogenesis. Moreover, POE inhibited the MAPKs/NF-κB axis and, consequently, MMP-2/9 activity. Overall, these results suggest that P. oceanica may be a potential weapon in the HCC additional treatment.
Retinal fluid is associated with cytokines of aqueous humor in age-related macular degeneration using automatic 3-dimensional quantification

Background: To explain the biological role of cytokines in the eye and the possible role of cytokines in the pathogenesis of neovascular age-related macular degeneration (nAMD) by comparing the correlation between cytokine of aqueous humor concentration and optical coherence tomography (OCT) retinal fluid. Methods: Spectral-domain OCT (SD-OCT) images and aqueous humor samples were collected from 20 nAMD patient’s three clinical visits. Retinal fluid volume in OCT was automatically quantified using deep learning--Deeplabv3+. Eighteen cytokines were detected in aqueous humor using the Luminex technology. OCT fluid volume measurements were correlated with changes in aqueous humor cytokine levels using Pearson’s correlation coefficient (PCC). Results: The patients with intraretinal fluid (IRF) showed significantly lower levels of cytokines, such as C-X-C motif chemokine ligand 2 (CXCL2) (p = 0.03) and CXCL11 (p = 0.009), compared with the patients without IRF. And the IRF volume was negatively correlated with CXCL2 (r = −0.407, p = 0.048) and CXCL11 (r = −0.410, p = 0.046) concentration in the patients with IRF. Meanwhile, the subretinal fluid (SRF) volume was positively correlated with vascular endothelial growth factor (VEGF) concentration (r = 0.299, p = 0.027) and negatively correlated with interleukin (IL)-36β concentration (r = −0.295, p = 0.029) in the patients with SRF. Conclusion: Decreased level of VEGF was associated with decreased OCT-based retinal fluid volume in nAMD patients, while increased levels of CXCL2, CXCL11, and IL-36β were associated with decreased OCT-based retinal fluid volume in nAMD patients, which may suggest a role for inflammatory cytokines in retinal morphological changes and pathogenesis of nAMD patients.
Does the Disparity Patterning Differ between Diagnosed and Undiagnosed Hypertension among Adults? Evidence from Indonesia

Background: Healthcare systems in many low- and middle-income countries (LMICs) are not yet designed to tackle the high and increasing burden of non-communicable diseases (NCDs), including hypertension. As a result, a large proportion of people with disease or risk factors are undiagnosed. Policymakers need to understand the disparity better to act. However, previous analyses on the disparity in undiagnosed hypertension, especially from LMICs, are lacking. Our study assessed the geographic and socioeconomic disparity in undiagnosed hypertension and compared it with diagnosed hypertension. Methods: We used the Basic Health Survey (Riskesdas) 2018 and performed geospatial and quantitative analyses across 514 districts in Indonesia. Dependent variables included diagnosed and undiagnosed hypertension among adults (18+ years) and by gender. Results: A high prevalence of undiagnosed hypertension at 76.3% was found, with different patterns of disparity observed between diagnosed and undiagnosed hypertension. Diagnosed hypertension was 1.87 times higher in females compared with males, while undiagnosed hypertension rates were similar between genders. Urban areas had up to 22.6% higher rates of diagnosed hypertension, while undiagnosed hypertension was 11.4% more prevalent among females in rural areas. Districts with higher education rates had up to 25% higher diagnosed hypertension rates, while districts with lower education rates had 6% higher rates of undiagnosed hypertension among females. The most developed regions had up to 76% and 40% higher prevalence of both diagnosed and undiagnosed hypertension compared with the least developed regions. Conclusion: The disparity patterning differs between diagnosed and undiagnosed hypertension among adults in Indonesia. This highlights the need for effective measures, including healthcare system reforms to tackle NCDs in LMICs.
The Effect of STEAM Learning on Improving Each Indicator of Students' Creative Thinking in Physics Learning

The research aims to analyze the effectiveness toward which STEAM learning improves each indication of students' creative thinking ability in physics learning. This research used a quantitative approach with a quasi-experimental design and a non-equivalent pretest-posttest control group design. In this research, the Class XI science students of SMA Negeri 1 Mentaya Hilir Utara during the 2022-2023 school year would present as the population. Class XI IPA I was selected as the experimental class, while class XI IPA II was presented as the control class in the sample. The collected research data will be analyzed using the Willcoxon test, the Mann-Whitney difference test, and the N-gain test. The improvement (N-Gain) of all indicators has reached the moderate category. Indications in the element of elaboration increased the highest, while indicators in the aspect of originality increased the lowest. Based on the improvement in each indicator and the results of regression tests on each indicator, it is demonstrated that STEAM learning has a very favorable effect on students' creative thinking abilities. STEAM-based learning is recommended for usage as an innovation in physics learning in schools in order to develop creative thinking.
