Relationships between spirituality and mental stress in people living with HIV in China: a cross-sectional study

ABSTRACT There are limited reports on the relationship between spirituality and mental stress in People living with HIV (PLWH) in China, who may be subject to anti-religious pressures from the government. In this study, we aimed to understand whether spirituality influences Chinese PLWH’s mental stress and, if so, at what level. We recruited 200 PLWHs from Beijing’s Ditan Hospital to complete a cross-sectional survey inquiring about their practice of spirituality as well as their level of mental stress. The study found that PLWH who presented with a mid-level of spirituality have the highest mental stress when compared to those who have a low level of spiritual beliefs or a high level of spiritual beliefs. This study points to the utility of healthcare providers taking PLWH’s potential spirituality into consideration, perhaps in particular for those with a moderate level of spirituality, in order to provide the most comprehensive care possible.
On the convergence of the point repeated symmetric single-step procedure for simultaneous estimation of polynomial zeros

The point symmetric single-step procedure established by Monsi (2012) has R-order of convergence at least 3. This procedure is modified by repeating the steps in the procedure �� times without involving function evaluations. This modified procedure is called the point repeated symmetric single-step PRSS1. The R-order of convergence of PRSS1 is at least (2��+1) (��≥ 1). Computational experiences in the implementation of the interval version of PRSS1 (see Monsi and Wolfe, 1988) showed that the repeated symmetric single-step procedure is more efficient than the total step (Kerner, 1966) and the single-step (Alefeld and Herzberger, 1974) methods.
On Software Infrastructure: Develop, Prove, Profit?

Having infrastructure survive over very long stretches of time is a non-trivial task. This is because such infrastructure either needs to be built extremely well from the outset, or because it requires ongoing maintenance. The former may require prohibitively large initial investment. The latter requires ongoing investment from public agencies over the span of decades or centuries despite the pendulum swings of those governments from contrasting political aims. Without either the very high initial or ongoing investment, infrastructure can fail. Physical infrastructure failure is not inevitable — consider railways in Japan, the Panama Canal, and the U.S. Interstate Highway System. Infrastructure challenges in the physical world has also led me to think more about the software infrastructure that facilities our society. I am not the first to refer to software as infrastructure, of course — we have long had the term cyberinfrastructure to encompass the numerous elements of hardware and software involved in computing, and software maintenance has been well established as a critical problem [1]. Nor am I the first to draw parallels between software development and bridge design [2]. Nonetheless, the problem persists. Ozment and Schechter’s wonderful “Milk or Wine: Does Software Security Improve with Age? ” [3] showed essentially that code that continues to be mostly just refined over time, like OpenBSD, ages (improves) like wine, whereas software that prioritizes adding features to refining functionality will age (sour) like milk. Of course most software vendors do prioritize adding features. Would today’s software be even be as robust as it is today if roughly 20 years ago, Bill Gates had not issued his “Trustworthy Computing” memo? Even aside from bugs introduced through unsound software deveopment practices, IEEE Security & Privacy Editorial Board members recently wrote on the subject of software supply chains and the degree to which we can trust developers to do the “right technical thing” [4] — inspired by the node-ipc sabotage.

Antibacterial Structure Design of Porous Ti6Al4V by 3D Printing and Anodic Oxidation

Titanium alloy Ti6Al4V is a commonly used bone implant material, primarily prepared as a porous material to better match the elastic modulus of human bone. However, titanium alloy is biologically inert and does not have antibacterial properties. At the same time, the porous structure with a large specific surface area also increases the risk of infection, leading to surgical failure. In this paper, we prepared three porous samples with different porosities of 60%, 75%, and 85%, respectively (for short, 3D-60, 3D-75, and 3D-85) using 3D printing technology and clarified the mechanical properties. Through tensile experiments, when the porosity was 60%, the compressive modulus was within the elastic modulus of human bone. Anodic oxidation technology carried out the surface modification of a 3D-printed porous titanium alloy with 60% porosity. Through change, the different voltages and times on the TiO2 oxide layer on the 3D-printed porous titanium alloy are different, and it reveals the growth mechanism of the TiO2 oxide layer on a 3D-printed unique titanium alloy. The surface hydrophilic and antibacterial properties of 3D-printed porous titanium alloy were significantly improved after modification by anodic oxidation.
Banach spaces in an analytic model of synthetic differential geometry

Les modeles bien adaptes de Geometrie Differentielle Synthetique [5] se construisent comme des topos de faisceaux sur des sites ou tous les objets sont de dimension finie. Pourtant, quand on applique a des objets representables des constructions importantes dans le topos, comme les exponentiels et les objets des parties, on obtient des objets de dimension infinie. Pour etudier ces objets il faut considerer le calcul differentiel dans les Espaces de Banach, comme l'amis en evidence Douady dans sa these [4]. Dans cet article nous construisons une immersion de la categorie des ensembles ouverts des Espaces de Banach complexes et des fonctions holomorphiques dans le modele analytique bien adapte de GDS introduit dans [7], et nous prouvons ainsi quelques proprietes importantes de cette immersion. En particulier, qu'elle preserve les produits et qu'elle est consistante avec le calcul differentiel, dans le sens que le calcul differentiel intrinseque synthetique dans le topos correspond aux constructions classiques de la theorie de I'holomorphie de dimension infinie. Ce faisant nous avons trouve et resolu quelques problemes interessants dans la theorie des. ideaux des fonctions analytiques de (plusieurs) variables complexes developpee par Cartan dans [2] et [3].
Pushing the Potential of Probe Microscopy

Musing over the most important scientific “sound bite” to pass onto future civilizations, Richard Feynman opted for: “All things are made of atoms—little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another. ” [1]. It is perhaps no wonder then that Feynman said that it was akin to a “religious experience” when he saw atoms for the first time with a scanning tunneling microscope (STM) [2]. We can only guess, but he would probably have been just as impressed with STM’s sibling technique, atomic force microscopy, which allows us to probe the atomic forces he found so elemental to our scientific understanding. Now, Christian Wagner from the Julich Research Center (Forschungszentrum Julich) in Germany and his coworkers have pushed the capabilities of force microscopy to a new level by attaching a single molecule at the sharp end of an STM probe and exploiting it as a quantum dot capable of sensing electrostatic fields [3]. The molecular quantum dot terminating the tip allows the electrostatic potential to be mapped out around a target atom or molecule, thus giving even deeper insights into the atomic-scale forces which so fascinated Feynman. The increased sensitivity offered by this technique could be used to characterize rough surfaces, adsorbed materials on semiconductors, or artificial nanostructures.
The Schur decomposition of the velocity gradient tensor for turbulent flows

The velocity gradient tensor for turbulent flow contains crucial information on the topology of turbulence, vortex stretching and the dissipation of energy. A Schur decomposition of the velocity gradient tensor (VGT) is introduced to supplement the standard decomposition into rotation and strain tensors. Thus, the normal parts of the tensor (represented by the eigenvalues) are separated explicitly from non-normality. Using a direct numerical simulation of homogeneous isotropic turbulence, it is shown that the norm of the non-normal part of the tensor is of a similar magnitude to the normal part. It is common to examine the second and third invariants of the characteristic equation of the tensor simultaneously (the $\unicode[STIX]{x1D64C}{-}\unicode[STIX]{x1D64D}$ diagram). With the Schur approach, the discriminant function separating real and complex eigenvalues of the VGT has an explicit form in terms of strain and enstrophy: where eigenvalues are all real, enstrophy arises from the non-normal term only. Re-deriving the evolution equations for enstrophy and total strain highlights the production of non-normality and interaction production (normal straining of non-normality). These cancel when considering the evolution of the VGT in terms of its eigenvalues but are important for the full dynamics. Their properties as a function of location in $\unicode[STIX]{x1D64C}{-}\unicode[STIX]{x1D64D}$ space are characterized. The Schur framework is then used to explain two properties of the VGT: the preference to form disc-like rather than rod-like flow structures, and the vorticity vector and strain alignments. In both cases, non-normality is critical for explaining behaviour in vortical regions.
The Role of Light Quality in Regulating Early Seedling Development

It is well−established that plants are sessile and photoautotrophic organisms that rely on light throughout their entire life cycle. Light quality (spectral composition) is especially important as it provides energy for photosynthesis and influences signaling pathways that regulate plant development in the complex process of photomorphogenesis. During previous years, significant progress has been made in light quality’s physiological and biochemical effects on crops. However, understanding how light quality modulates plant growth and development remains a complex challenge. In this review, we provide an overview of the role of light quality in regulating the early development of plants, encompassing processes such as seed germination, seedling de−etiolation, and seedling establishment. These insights can be harnessed to improve production planning and crop quality by producing high−quality seedlings in plant factories and improving the theoretical framework for modern agriculture.
The Influence of School Based Menstrual Hygiene Management Programs on School Attendance among Girls in Public Primary Schools in Kisumu West Sub-County, Kisumu County, Kenya

Most governments have prioritized Menstrual Hygiene Management (MHM) practices for safe schools. However, girls and women in Low and Middle-Income Countries (LMIC) still face significant challenges in managing their menstruation. This study examined the influence of school based MHM Programs on school attendance among girls in public Primary schools in Kisumu west sub-county, Kisumu County, Kenya. The study was anchored on the Sanitary Hardware theory. The study employed descriptive survey research design where both qualitative and quantitative methods were used. Questionnaires were administered to a selected sample of 356 respondents drawn from a target population of 3233. The sample size was arrived at using the Yamane (1967) formula. The respondents consisted of class 6-8 girls, teachers, Head-Teachers, and MoE officials who were key informants for the study. The collected data was filtered, organized, coded and later analyzed using Statistical Package for Social Sciences (SPSS) version 22 software. Analysis was done in form of descriptive and inferential statistics. From the findings, the F ratio is 111.855, which means that improvement due to fitting the model is much greater than the model inaccuracies (F (1, 336) = 111.855, p=0.001). This implies that Menstrual Hygiene Management school-based programs are useful predictor of school attendance. The researcher therefore recommends that schools should be able to ensure consistent availability of water for use by girls during menstruation. They should be empowered to involve themselves in making reusable pads to assist those who cannot afford disposable pads use locally available materials in menstrual management.

The amount of unstructured data is increasing annually, which is promising forgaining insights. Twitter, a platform producing unstructured data, is currently one of the mostpopular media platforms used for conducting research on a topic's trend. This study attempts toanalyze the topic of New and Renewable Energy (NRE) in Indonesia. The purpose of this studyis to gain insights into the NRE topic trend over the last ten years by modeling the topicsdiscussed on Twitter and examining the location distribution of users who post tweets about thetopic. Accordingly, this study employed descriptive analysis, geocoding analysis, and topicmodeling. The results of descriptive analysis show that the development of NRE has acceleratedin recent years, particularly in 2021. Geocoding analysis reveals that the distribution of peoplewho engage in NRE posting activities is dominated by DKI Jakarta province. Topic modelingyielding two topics that were discussed the most by Indonesians over a 10-year period. The twotopics are related to government policies that support the development of NRE and electricity,which is Indonesia's focus in NRE. This study highlights the importance of analyzing theTweetology of NRE.
Social media marketing: How can it be equally efficient for both men and women segments?

One of the most rapidly rising technologies of our day, social networking platforms is used by billions of consumers throughout the world. The marketing environment is constantly evolving as a direct result of the widespread use of various social media platforms. It's not unexpected that marketers have started embracing the use of social media as an advertising approach, given the massive audiences available that spend several hours per day utilizing social networking across a variety of platforms for information processing, entertainment, and social connections. There are already significant corporate values placed on the ways in that social media may be used to influence customer views and purchases. As a result, businesses are using social media mechanisms to strengthen relationships with clients. To reap the advantages of social media, both firms, and consumers need to adapt to the new norms. In light of this, the research endeavored to emphasize the role that user-generated content plays in the marketing of businesses, as well as to predict what social media channels and industries businesses should focus on in the future, and how doing so would alter the gender balance in such domains. Is it true that women are more likely to be influenced by commercials than men? This study sets out to quantify the influence of television commercials on the purchasing decisions of female college students. Social media campaigns that specifically target women have been demonstrated to provide better results than those that focus on men. The findings of this study will be useful for influencing businesses and marketing departments to increase their budgets for social media advertising and for assisting those departments already engaged in this field. Marketers interested in expanding their reach on social media platforms or improving their understanding of customer behavior may find this research useful.
Modeling multivariate time series with copulas: Implications for pricing revenue insurance

Much of the soybean produced in Brazil is exported and, consequently, the domestic soybean price (R$) is greatly influenced by the price traded at the Chicago Mercantile Exchange Group (CME Group) (US$). Therefore, to model the dependency structure between soybean yield and price, the exchange rate must be incorporated into the modeling. This study aims to model the dependency structure between these three variables using the Copula methodology, calculate the crop revenue insurance rates, and compare with the rates offered in the insurance market. The rates applied by the Brazilian insurance market are overpriced when compared to the methodology presented in this study with the incorporation of the dollar rate in the modeling, which could increase the problem of adverse selection exchange and hamper massification of agricultural insurance in the Brazilian territory.
Intraoperative awareness with recall during General Anaesthesia in Damascus University Hospitals in Syria

Background: Awareness with recall during general anesthesia is one of the frightening complications of general anesthesia, which indicates the failure of anesthesia. Awareness is an underestimated complication despite the fact that it sometimes carries devastating psychological risks for patients. To our knowledge this is the first research in Syria that reports the incidence of awareness with recall during general anesthesia. Aims: to assess the incidence of awareness with recall during general anesthesia in Damascus University teaching hospitals. Design: Multi-central prospective cohort study. Setting: Three main Teaching Hospitals of Damascus University: Al-Assad, Al-Mowassat & Maternity Hospitals during the time period between January and November 2021. Study Sample: 3500 patients aged ≥ 18 years were included. Results: the incidence of Awareness with recall during general anesthesia in Damascus University Teaching Hospitals was 0.66% in low risk of awareness surgery and 1.8% in high risk of awareness surgeries. The most frequent manifestations of awareness were auditory perceptions, paralysis and pain (100%, 100% & 97.4% respectively). Conclusions: Awareness with recall rate was somehow high in Damascus University Teaching Hospitals in comparison to the figures reported by American and European studies, this difference was especially noted in a low risk of awareness surgery. The rates were similar in the high risk of awareness surgeries. Lack of premedication and low concentration of inhalational agent were the main reasons for awareness.
Systematic analysis of the prognosis and immune infiltration of E2Fs in thyroid carcinoma

Purpose: To evaluate the diagnostic and prognostic utility of E2F transcription factors (E2Fs) in thyroid carcinoma (THCA) and their association with immune infiltration. Methods: The transcription and protein levels of E2Fs in THCA tissues were examined using the R language and the Human Protein Atlas (HPA) database in this research. We utilized the UALCAN and GEPIA2 databases to analyze the association between the level of E2Fs and the clinicopathological features of THCA. The prognostic utility of E2F expression in THCA was studied using the R language and the Gene Set Cancer Analysis (GSCA) database. Over-representation analysis (ORA) and gene set enrichment analysis (GSEA) were employed to analyze the effect of E2F family members. The TISIDB database and Tumor Immune Estimation Resource (TIMER) database were utilized to investigate the relationship between E2F expression and the level of immune infiltration in thyroid cancer. Results: E2Fs are highly conserved in thyroid carcinoma and rarely mutated. E2Fs are strongly expressed in THCA and are highly related with the clinicopathological stage of THCA. Patients with THCA have a poor prognosis when E2Fs are highly expressed. The function of E2Fs in THCA may be closely related to the renin–angiotensin system (Ras) signaling pathway, platelet-derived growth factor (PDGF) signaling pathway, apoptosis, and immune response. With regard to the immune infiltration, E2F expression and tumor-infiltrating lymphocytes exhibited a positive connection. Conclusion: The level of E2Fs is connected with the prognosis and immune infiltration level in THCA, revealing that E2Fs may be a prognostic and immune infiltration cell marker in THCA patients.
Microwave linear polarization rotator in a bilayered chiral metasurface based on strong asymmetric transmission

We propose and study a kind of bilayered chiral metasurface (BCM) composed of complementary L-shaped resonators with a lossless dielectric spacer that can realize linear polarization rotation with ultrahigh conversion efficiency. We present a theoretical analysis of the BCM with specific chiral geometry that enables asymmetric transmission for linear polarization only. Numerical results show that the proposed metasurface has dual-band asymmetric transmission with nearly 100% cross-polarization conversion efficiency when the loss is ignored. More importantly, depending on the incident direction, only one of the cross-polarization transmissions can approach unity while all the remaining transmissions are close to zero. As a result, nearly perfect linear polarization rotation is achieved for a particular polarization direction. We further show that the working frequency and the bandwidth of the proposed BCM can be tuned by adjusting the geometric size and spatial arrangement of the unit cell.
Broad band absorber based on cascaded metamaterial layers including graphene

Abstract In order to extend the absorption band of the metamaterial with tilted graphene sheets, we use cascaded metamaterial layers and study the dependence of absorption on the structure parameters. The absorption spectra can be obtained through the transfer matrix method that we derive from the special metamaterial. The individual band of these metamaterial layers could be adjusted by modifying their geometrical and electrical parameters. We find that the absorption bandwidth of cascaded structure can be much increased with the number of layers increasing.
