Glyphosate and Aminomethylphosphonic Acid (AMPA) Modulate Glutathione S-Transferase in Non-Tumorigenic Prostate Cells

Glyphosate (GLY) was developed in the early 1970s and has become the most used broad-spectrum herbicide in the world so far. Its main metabolite is aminomethylphosphonic acid (AMPA), and the accumulation of GLY and its derivative compounds raises some concerns regarding possible health outcomes. In this study, we aimed to evaluate the effects of GLY and AMPA on prostate cell lines by evaluating cell viability, proliferation, gene and protein expression, and cellular pathways involved in the response to oxidative stress. Our results indicated that GLY and AMPA reduced the cell viability of tumorigenic and non-tumorigenic prostate cell lines only at higher concentrations (10 mM GLY and 20 mM AMPA). In contrast, both compounds increased the clonogenicity of non-tumorigenic PNT2 cells, mainly at concentrations below the IC50 (5 mM GLY and 10 mM AMPA). Moreover, treatment of non-tumorigenic cells with low concentrations of GLY or AMPA for 48 h increased GSTM3 expression at both mRNA and protein levels. In contrast, the treatments decrease the GST activity and induced an increase in oxidative stress, mainly at lower concentrations. Therefore, both compounds can cause cellular damage even at lower concentrations in non-tumorigenic PNT2 cells, mainly affecting cell proliferation and oxidative stress.
AN ANALYSIS OF THE FACTORS THAT IMPACT THE CUSTOMERS’ SATISFACTION ON ONLINE FOOD DELIVERY SERVICES IN PETALING JAYA, SELANGOR, MALAYSIA

Gender equality in education has been an issue of interest in developing strategies for This research focuses on customer satisfaction with Malaysia's online food delivery (OFD) services. In this decade, the number of individuals who frequently purchased meals online climbed dramatically. People nowadays prefer their meals to be delivered instead of dining in a restaurant. Hence, it is crucial to understand the customers' expectations to manage a successful meal delivery business. People used to have to dine at restaurants or order takeout, but today OFD businesses provide convenience and have transformed customer behavior. This study also investigates the intrinsic and extrinsic factors influencing Malaysian's meal delivery satisfaction. Questionnaires were distributed to consumers in Petaling Jaya metropolitan area to collect and analyze data for this study. 384 respondents contributed to this study's findings, discussion, and conclusion. This study tested three independent variables that influence customers' satisfaction: hedonic motivation, price-saving orientation, and time-saving orientation. As a result, this study's three independent variables were statistically significant in satisfying customers. In conclusion, this study can be used to increase the usage of OFD services in the future. However, there are many factors to consider, as it was proven that the three independent factors positively contribute to customer satisfaction. Thus, the OFD service developers must create a solid impression that using OFD services is engaging and intriguing. Additionally, marketers must foster the idea that OFD services are integral to the user's lifestyle. Article visualizations:
Assessing Global Efforts in the Selection of Vertebrates as Umbrella Species for Conservation

Simple Summary Conservation funds and resources have long been globally inadequate, and methods that could maximize conservation outcomes with limited investment, such as umbrella-species strategies, are thus needed to address the current biodiversity crisis. In this study, we summarized 242 published scientific articles and found 213 terrestrial vertebrates that were recommended as umbrella species. We summarized global trends in umbrella species selection and research during the past four decades, with North America, Europe, and Asia over-representing umbrella-related studies, and thus, more umbrella species recommendations have occurred in the Northern Hemisphere. Generally, there has been a bias toward recommending bird and mammal species, wide-ranging species, and non-threatened species, such as umbrellas, and grouses (order Galliformes) and large carnivores have often been recommended as umbrellas across different continents by multiple studies. Given observed biases and trends, we raise concerns about neglecting amphibians and reptiles, the over-preference for wide-ranging and non-threatened species, and recommend little-known species. We argue that conservation umbrella strategies can be cost-effective and successful given that appropriate species are chosen in the right location, and our findings could inform future conservation research and practices using conservation umbrella strategies. Abstract The umbrella-species strategy has been proposed as an attainable tool to achieve multi-species and community conservation with limited investment. There have been many umbrella-related studies since the concept’s inception; thus, a summary of global study efforts and recommended umbrella species is important for understanding advances in the field and facilitating conservation applications. Here, we collated 213 recommended umbrella species of terrestrial vertebrates from 242 scientific articles published during 1984–2021 and analyzed their geographic patterns, biological features, and conservation statuses to identify global trends in the selection of umbrella species. We found a considerable geographic bias: most studies and, consequently, recommended umbrella species are from the Northern Hemisphere. There is also a strong taxonomic bias, with grouses (order Galliformes) and large carnivores being the most popular umbrella species and amphibians and reptiles being largely overlooked. In addition, wide-ranging and non-threatened species were frequently recommended as umbrella species. Given the observed biases and trends, we caution that appropriate species need to be chosen for each location, and it is important to confirm that popular, wide-ranging species are effective umbrella species. Moreover, amphibians and reptiles should be investigated for their potential as umbrella species. The umbrella-species strategy has many strengths and, if applied appropriately, may be one of the best options in today’s conservation research and funding landscape.
A semi‐Lagrangian level set method for incompressible Navier–Stokes equations with free surface

In this paper, we formulate a level set method in the framework of finite elements‐semi‐Lagrangian methods to compute the solution of the incompressible Navier–Stokes equations with free surface. In our formulation, we use a quasi‐monotone semi‐Lagrangian scheme, which is both unconditionally stable and essentially non oscillatory, to compute the advective terms in the Navier–Stokes equations, the transport equation and the equation of the reinitialization stage for the level set function. The method we propose is quite robust and flexible with regard to the mesh and the geometry of the domain, as well as the magnitude of the Reynolds number. We illustrate the performance of the method in several examples, which range from a benchmark problem to test the volume conservation property of the method to the flow past a NACA0012 foil at high Reynolds number.

Buoyancy-driven convection with a uniform magnetic field. Part 1. Asymptotic analysis

We study the convection of an electrically conducting liquid in a horizontal cylinder (horizontal Bridgman configuration). A uniform steady vertical magnetic field is externally imposed. The thermal and magnetic Prandtl numbers are assumed equal to zero. The thermal field is obtained assuming pure conduction and certain conditions at the boundaries, so that the heat flux is axial and uniform. The influence of the cylinder's cross-sectional shape is examined. In the high Hartmann number limit (Ha [Gt ] 1), an analytical solution is found for the fully established flow. With electrically insulating walls, the magnetically damped convective velocity varies as Ha-2 when the cross-section has a horizontal plane of symmetry, while it varies as Ha-1 for non-symmetrical shapes. When the walls are perfectly conducting, the damped velocity always varies as Ha-2.
A qualitative study of women care professionals’ experiences in social service non-profit organizations in Israel

ABSTRACT Although women play a significant role in non-profit organizations as employees, volunteers, and clients, there is insufficient knowledge about these women and their unique work experiences in the current era, which is characterized by outsourcing of social services. This study explored work experiences among women in professional care settings of social service non-profit organizations (SSNPOs). Forty in-depth interviews were conducted with women with postsecondary education working as care professionals (such as social workers and occupational therapists) in Israeli SSNPOs. The sample reflected Israel’s geographical, religious, ethnic, and job (full-time and part-time) diversity. Interviewees were asked about their employment experiences, struggles, and challenges. Thematic analysis was used. The findings shed light on how care work in SSNPOs enters the private sphere and is internalized, i.e. boundaries between home and work that are continuously blurred and endanger employees’ well-being. Our study suggests that women working in care professions in contracted SSNPOs are more vulnerable due to their working conditions, despite their postsecondary education and defined professions. Negative psychosocial outcomes are the major challenge for this population.
Role of the edge orbits in the semiclassical quantization of the stadium billiard

In the periodic orbit quantization of the stadium billiard, we show that important contributions may be due to the edge orbits, i.e. to orbits bouncing between points where the curvature of the boundary is discontinuous. We explicitly show that these edge orbits are necessary to reproduce several amplitudes of the length spectrum defined by the Fourier transform of the staircase function. In this way, we explain some features overlooked in recent experiments on microwave cavities.
Impact of pre-illumination in PVK-based photorefractive polymers for holographic imaging applications

A poly(N-vinylcarbazole) (PVK) based photorefractive (PR) composite has been used as recording medium in a holographic setup designed for time gated holographic imaging (TGHI). A loss of sensitivity is observed when the performance of the material is probed with a femtosecond (fs) laser and a superluminescence diode (SLD) as short coherence light sources. It is known that the reduction in sensitivity can be compensated by different chemical and physical approaches. Here we report on a first step of a comprehensive pre-illumination (PI) series experiments with red and near infrared (NIR) laser light to gain deeper insight into the microscopic mechanism of the PI effect and to overcome the loss of sensitivity. PI with red laser light increases the recording time while simultaneous PI with one of the write beams affects the response time only slightly.
ON THE FABER-KRAHN INEQUALITY FOR THE DIRICHLET p-LAPLACIAN ∗

A famous conjecture made by Lord Rayleigh is the following: “The first eigenvalue of the Laplacian on an open domain of given measure with Dirichlet boundary conditions is minimum when the domain is a ball and only when it is a ball”. This conjecture was proved simultaneously and independently by Faber [G. Faber, Beweiss dass unter allen homogenen Membranen von gleicher Flache und gleicher Spannung die kreisforfegige den leifsten Grundton gibt. Sitz. bayer Acad. Wiss. (1923) 169–172] and Krahn [E. Krahn, Uber eine von Rayleigh formulierte Minimaleigenschaftdes Kreises. Math. Ann. 94 (1924) 97–100. ]. We shall deal with the p -Laplacian version of this theorem.
A Survey of Weighted Polynomial Approximation with Exponential Weights

Let W : R → (0,1] be continuous. Bernstein’s approximation problem, posed in 1924, deals with approximation by polynomials in the weighted uniform norm f → k fW k L1(R). The qualitative form of this problem was solved by Achieser, Mergelyan, and Pollard, in the 1950’s. Quantitative forms of the problem were actively investigated starting from the 1960’s. We survey old and recent aspects of this topic, including the Bernstein problem, weighted Jackson and Bernstein Theorems, Markov–Bernstein and Nikolskii inequalities, orthogonal expansions and Lagrange interpolation. We present the main ideas used in many of the proofs, and different techniques of proof, though not the full proofs. The class of weights we consider is typically even, and supported on the whole real line, so we exclude Laguerre type weights on [0, ∞). Nor do we discuss Saff’s weighted approximation problem, nor the asymptotics of orthogonal polynomials.
First complete seasonal variation study of the 3D optical turbulence above San Pedro Martir Observatory

The first complete seasonal variation study extended over 1 year (~80 nights uniformly distributed along twelve months) of all the principal astroclimatic parameters (CN2, seeing ε, wavefront coherence time τO, isoplanatic angle θ0, scintillation rate σI2, isoplanatic angle for the MCAO θM - where M is the number of the deformable mirrors DMs - M=1,2,3,.) simulated with an atmospherical model (Meso-Nh) above the San Pedro Martir Observatory is presented. The atmospherical model run in an autonomous way to simulate CN2 and wind speed vertical profiles (over ~20 km) related to the 80 nights after it has been calibrated with the support of a few CN2 measurements. All the integrated parameters are calculated using these two basic elements and general seasonal trends are put in evidence. The impact of our results on the adaptive optics techniques (AO) is discussed as well as the potentialities of the numerical simulations as a new tool for the climatologic analysis of the optical turbulence above astronomical sites.
Formation of Leading Vortex Pair in Two-Dimensional Starting Jets

The vortex formation process in a two-dimensional starting jet at Reynolds numbers ranging from 1500 to 3400 has been investigated experimentally. The present results show that the formation of leading vortex pair can be restricted by the growth of secondary vortices from trailing shear-layer instability. The detachment of the leading vortex pair is found to be analogous to the pinchoff process of an axisymmetric vortex ring formation. The critical formation number F for the vortex pair is identified to be around 7, higher than the value of 4 for the vortex ring formation. Because of the nonsaturated state of the vortex pair, the main mechanisms responsible for the vortex ring pinchoff (i.e., the Kelvin–Benjamin variational principle) may not be applicable in the two-dimensional cases. As such, the vortex pair pinchoff at higher Reynolds number can be attributed largely to the roll-up and growth of the secondary vortices in the trailing shear layer. The present results suggest that the shear-layer instabi.
STRUCTURE AND STABILITY OF A SPHERICAL SHOCK WAVE IN A VAN DER WAALS GAS

Strong spherical shock waves are studied for an imperfect gas, here modelled by a van der Waals equation of state. Similarity solutions of Guderley type are shown to exist, in which the radius of the shock is proportional to (-t) α , where t is time measured from the moment at which the shock focuses. The exponent a depends on both the ratio of specific heats, γ, and on the van der Waals excluded volume, b. For small b, the solution resembles the Guderley solution and is well described by the Chester-Chisnell-Whitham (CCW) approximation. A new branch of solutions, which the CCW approximation fails to locate, is shown to exist for larger b. The linear stability of the similarity solutions is examined directly, without the use of the CCW approximation. Normal modes grow (Re (β) 0) as (-t) αβ , where the 'growth rate', β, is a function of γ, b and n, the spherical harmonic wavenumber. No physically meaningful, discrete, spherically symmetric (n = 0) modes were found. This case was examined numerically and nonlinearly for shocks launched by a spherical 'piston'; no evidence of instability was discovered.
Deep Learning-Based Univariate Prediction of Daily Rainfall: Application to a Flood-Prone, Data-Deficient Country

There are several attempts to model rainfall time series which have been explored by members of the hydrological research communities. Rainfall, being one of the defining factors for a flooding event, is rarely modeled singularly in deep learning, as it is usually performed in multivariate analysis. This study will attempt to explore a time series modeling method in four subcatchments located in Samar, Philippines. In this study, the rainfall time series was treated as a signal and was reconstructed into a combination of a ‘smoothened’ or ‘denoised’ signal, and a ‘detailed’ or noise signal. The discrete wavelet transform (DWT) method was used as a reconstruction technique, in combination with the univariate long short-term memory (LSTM) network method. The combination of the two methods showed consistently high values of performance indicators, such as Nash–Sutcliffe efficiency (NSE), correlation coefficient (CC), Kling–Gupta efficiency (KGE), index of agreement (IA), and Legates–McCabe index (LMI), with mean average percentage error (MAPE) values at almost zero, and consistently low values for both residual mean square error (RMSE) and RMSE-observations standard deviation ratio (RSR). The authors believe that the proposed method can give efficient, time-bound results to flood-prone countries such as the Philippines, where hydrological data are deficient.
On combining multiple classifiers by fuzzy templates

The authors study classifier fusion using the fuzzy template (FT) technique. Given an object to be classified, each classifier from the pool yields a vector with degrees of "support" for the classes, thereby forming a decision profile. A fuzzy template is associated with each class as the averaged decision profile over the training samples from this class. A new object is then labeled with the class whose fuzzy template is closest to the objects' decision profile. They give a brief overview of the field to place the FT approach in a proper group of classifier combination techniques. Experiments with two data sets (satimage and phoneme) from the ELENA database demonstrate the superior performance of FT over a version of majority voting, aggregation by fuzzy connectives (minimum, maximum, and product), and (unweighted) average.
The Impact of Government Performance Evaluation on Environmental Performance in Organizations

Abstract Using GPE performance gaps (the difference between actual and standard levels of performance), this article explores the relationship between the GPE outcomes of public organizations and their environmental performance (EP). We utilize Korean GPE data related to qualitative/quantitative and financial/non-financial performance indicators that the government uses to evaluate public organizations. The GPE does not cover every important environmental activity in which public organizations may engage; the EP measure can incorporate results from all environmental activities, even those excluded from the GPE. Our investigation revealed that the EP of public organizations varied according to their GPE performance gaps. Low GPE performers favored GPE-included environmental activities over GPE-excluded environmental activities, but high GPE performers engaged in environmental activities were excluded from the GPE. A negativity bias occurs when public organizations adjust their environmental activities in response to GPE performance gaps. For environmental activities excluded from the GPE, low GPE performers avoided them more than high GPE performers engaged in them. These findings indicate the importance of a well-designed organizational performance evaluation for balanced engagement in environmental initiatives. This article is of theoretical interest to academics and has practical value for practitioners.
Robust non-parametric smoothing of non-stationary time series

Motivated by the need of extracting local trends and low frequency components in non-stationary time series, this paper discusses methods of robust non-parametric smoothing. Basic approach is the combination of the parametric M-estimation with kernel and local polynomial regression methods. The result is an iterative estimator that retains a linear structure, but has kernel weights also in the direction of the prediction errors. The design of smoothing coefficients is carried out with robust cross-validation criteria and rules of thumb. The method works well both to remove the influence of patches of outliers and to detect the local breaks and persistent structural change in time series.
Clinical Usefulness of Right Ventricle–Pulmonary Artery Coupling in Cardiovascular Disease

Right ventricular–pulmonary artery coupling (RV-PA coupling) refers to the relationship between RV contractility and RV afterload. Normal RV-PA coupling is maintained only when RV function and pulmonary vascular resistance are appropriately matched. RV-PA uncoupling occurs when RV contractility cannot increase to match RV afterload, resulting in RV dysfunction and right heart failure. RV-PA coupling plays an important role in the pathophysiology and progression of cardiovascular diseases. Therefore, early and accurate evaluation of RV-PA coupling is of great significance for a patient’s condition assessment, clinical decision making, risk stratification, and prognosis judgment. RV-PA coupling can be assessed by using invasive or noninvasive approaches. The aim of this review was to summarize the pathological mechanism and evaluation methods of RV-PA coupling, the advantages and disadvantages of each method, and the application value of RV-PA coupling in various cardiovascular diseases.
Circle of success—An interpretative phenomenological analysis of how Black engineering students experience success

Though minoritized undergraduate engineering students earn less than 25% of engineering bachelor's degrees, minority‐serving institutions (MSIs) are leading the way in producing a large percentage of those underrepresented engineering bachelor's degree holders. However, much of the published research about the experiences of underrepresented engineering students occurs within the context of predominantly White institutions. Upon deeper inspection into the apparent success of some MSIs, graduation rates of specific minoritized populations (e.g., Black students) remain critically low. This suggests that there is more to be learned about how to better support Black engineering students' success.
