Head Waves in Modified Weiskopf Sandy Medium

In this study, a modified anisotropic elastic Weiskopf model for a sandy medium was introduced, satisfying the highest rotational symmetry compatible with a Weiskopf sandiness parameter greater than the unity. The developed approach was applied for computing and comparing head SP waves propagating along the free surface of the halfspace. The comparison revealed a substantial discrepancy in the SP wave pulses detected at the points of observation. The developed models for the generation and detection of SP waves are based on the FEA (finite element analysis) of the inner Lamb problem.
A prognostic nomogram for the cancer-specific survival of white patients with invasive melanoma at BANS sites based on the Surveillance, Epidemiology, and End Results database

Objective The purpose of this study was to develop a comprehensive nomogram for the cancer-specific survival (CSS) of white patients with invasive melanoma at back, posterior arm, posterior neck, and posterior scalp (BANS) sites and to determine the validity of the nomogram by comparing it with the conventional American Joint Committee on Cancer (AJCC) staging system. Methods This study analyzed the patients with invasive melanoma in the Surveillance, Epidemiology, and End Results (SEER) database. R software was used to randomly divide the patients into training and validation cohorts at a ratio of 7:3. Multivariable Cox regression was used to identify predictive variables. The new survival nomogram was compared with the AJCC prognosis model using the concordance index (C-index), area under the receiver operating characteristic (ROC) curve (AUC), net reclassification index (NRI), integrated discrimination index (IDI), calibration plotting, and decision-curve analysis (DCA). Results A novel nomogram was established to determine the 3-, 5-, and 8-year CSS probabilities of patients with invasive melanoma. According to the nomogram, the Age at Diagnosis had the greatest influence on CSS in invasive melanoma, followed by Bone Metastasis, AJCC, Stage, Liver Metastasis, Histologic Subtype, Brain Metastasis, Ulceration, and Primary Site. The nomogram had a higher C-index than the AJCC staging system in both the training (0.850 versus 0.799) and validation (0.829 versus 0.783) cohorts. Calibration plotting demonstrated that the model had good calibration ability. The nomogram outperformed the AJCC staging system in terms of AUC, NRI, IDI, and DCA. Conclusion This was the first study to develop and evaluate a comprehensive nomogram for the CSS of white patients with invasive melanoma at BANS sites using the SEER database. The novel nomogram can assist clinical staff in predicting the 3-, 5-, and 8-year CSS probabilities of patients with invasive melanoma more accurately than can the AJCC staging system.
Development of the Engineering Design Process (EDP) on the Ability to Design Prototypes to Increase Natural Disaster Mitigation for Elementary Schools in Indonesia

Education is the most essential part in every aspect of providing the quality of human resources. Thus, one of the learning innovations to improve quality, especially for children, is the engineering design process. The engineering design process (EDP) is a set of processes that engineers use to solve an issue. The purpose of this study is to find out the of EDP on design prototypes of the elementary school. The application of knowledge and capability through EDP were also able to develop critical and creative thinking skills so that they can solve problems, collaborate, and communicate. The method adopted in this research is case study. Seventeen elementary students from four different schools in three different cities in province Riau, Indonesia, are selected as participants. Data are collected through interviews and analyzed using a grounded approach. Finding of this study EDP became an ability that could involve students in the learning space and students were also challenged to work collaboratively in groups that were guided by researchers. From the designs made by students, the level of ability to design student prototypes was dominated by the level of the developing stage even to the level of the continuous stage. The findings indicated that the activities using EDP were able to help students to experience real learning and find components that can be used to compound a tool and solve real problems. The findings also indicate the need to reform curriculum for teacher training programs through EDP to include matters like design prototypes.
Radar Observations of Tornado-Warned Convection Associated with Tropical Cyclones over Florida

AbstractStatistical evaluations of tornado warnings issued during recent tropical cyclone events yielded an above-average false alarm ratio. This study analyzed tornado-warned convection associated with Tropical Storms Debby (2012) and Andrea (2013) using superresolution and dual-polarization data from Weather Surveillance Radar-1988 Doppler radars located throughout the Florida peninsula to identify precursor characteristics and signatures that would distinguish tornadic events prior to tornadogenesis. A series of radar-based interrogation guidance at varying ranges from radar is presented to help facilitate the reduction of the tornado-warning false alarm ratio without compromising the probability of detection. For convection within 74.1 km from the nearest radar, low-level velocity characteristics include a rotational velocity ≥ 10.3 m s−1 (20 kt), shear across the rotation ≥ 0.010 s−1, and a contracting rotation diameter. The convection should also exhibit supercell reflectivity signatures and at leas.
Intravenous Immunoglobulin in Kawasaki Disease—Evolution and Pathogenic Mechanisms

Kawasaki disease (KD) is an acute vasculitis of childhood that affects the medium vessels with a special predilection to the involvement of coronary arteries. The major morbidity of this disease is due to coronary artery aneurysm, which occurs in about 25–30% of untreated cases. For decades now, intravenous immunoglobulin (IVIg) has consistently been shown to reduce the risk of CAAs to less than 5%. However, the mechanism of immunomodulation remains unclear. Several studies on the role of IVIg in the modulation of toll-like receptor pathways, autophagy, and apoptosis of the mononuclear phagocytic system, neutrophil extracellular trap, and dendritic cell modulation suggest a modulatory effect on the innate immune system. Similarly, certain studies have shown its effect on T-cell differentiation, cytokine release, and regulatory T-cell function. In this review, we discuss the potential mechanisms underlying the immunomodulatory actions of IVIg in patients with Kawasaki disease. Furthermore, we provide a summary of the evidence regarding various infusion protocols and dosages utilized in the treatment of KD patients.
AN EXTREME LUMINOUS X-RAY SOURCE CATALOG BASED ON CHANDRA ACIS OBSERVATIONS

Using Chandra archive data we conduct a thorough survey of luminous X-ray sources. We directly analyze about 9400 ACIS Observations and cross-correlate the X-ray sources with 77,000 galaxies within 250 Mpc. The final catalog includes 119 unique luminous X-ray source candidates with L X > 3 × 10 40 erg s − 1 ? > from 93 galaxies or 41 HLX candidates with L X > 1 × 10 41 erg s − 1 ? > from 35 galaxies. We derive a moderate contamination rate due to foreground or background sources. We also cross-correlate the catalog with FIRST, perform variability and periodicity tests, and analyze one HLX candidate in particular. Our catalog could be a starting point to perform follow-up observations.
Stochastic Modelling, Analysis, and Simulations of the Solar Cycle Dynamic Process

Analytical solutions, discretization schemes and simulation results are presented for the time delay deterministic differential equation model of the solar dynamo presented by Wilmot-Smith et al. In addition, this model is extended under stochastic Gaussian white noise parametric fluctuations. The introduction of stochastic fluctuations incorporates variables affecting the dynamo process in the solar interior, estimation error of parameters, and uncertainty of the α-effect mechanism. Simulation results are presented and analyzed to exhibit the effects of stochastic parametric volatility-dependent perturbations. The results generalize and extend the work of Hazra et al. In fact, some of these results exhibit the oscillatory dynamic behavior generated by the stochastic parametric additative perturbations in the absence of time delay. In addition, the simulation results of the modified stochastic models influence the change in behavior of the very recently developed stochastic model of Hazra et al.
Association Between Opioid Use and Risk of Sexual Dysfunction: A Systematic Review

Opioid use disorder (OUD) is defined by negative effects on oneself despite numerous efforts to stop it. Chronic opioid users have sexual dysfunctions such as erectile dysfunction, delayed ejaculation decreased libido, and sexual performance. To explore the association between the use of opioids and the risk of sexual dysfunction. This review was conducted from March 2023 to June 2023, and comprised of search on PsycINFO, MEDLINE, EMBASE, Google Scholar, OvidSP Science Direct, PubMed, Clinical Trials.gov, and Web of Science databases for experimental studies and randomized controlled trials related to OUDs published in peer-reviewed English-language journals between 2013 and 2023 (10 years). Of the 314 studies initially identified, 41(13%) were subjected to full-text assessment, and 10 were reviewed and analyzed (Figure). There were 2(20%) each study done in Egypt and Istanbul and 1(10) each in Germany, Canada, Spain, China, Poland, and Malaysia. All 10 (100%) studies were baes on opioid use and sexual dysfunction. Prospective studies showed that the occurrence of any sexual dysfunction ranged from 40% to 90% of opioid dependence. The most commonly studied observed sexual dysfunction is a lack of desire, erectile dysfunction, erectile dysfunction, and poor satisfaction. Our findings suggest that there is a significant link between opioid use and sexual dysfunction and that people who use opioids have higher rates of sexual dysfunction. Nevertheless, opioids have mind-altering properties that negatively affect various stages of the sexual cycle.
Impact of Exposomes on Ocular Surface Diseases

Ocular surface diseases (OSDs) are significant causes of ocular morbidity, and are often associated with chronic inflammation, redness, irritation, discomfort, and pain. In severe OSDs, loss of vision can result from ocular surface failure, characterised by limbal stem cell deficiencies, corneal vascularisation, corneal opacification, and surface keratinisation. External and internal exposomes are measures of environmental factors that individuals are exposed to, and have been increasingly studied for their impact on ocular surface diseases. External exposomes consist of external environmental factors such as dust, pollution, and stress; internal exposomes consist of the surface microbiome, gut microflora, and oxidative stress. Concerning internal exposomes, alterations in the commensal ocular surface microbiome of patients with OSDs are increasingly reported due to advancements in metagenomics using next-generation sequencing. Changes in the microbiome may be a consequence of the underlying disease processes or may have a role in the pathogenesis of OSDs. Understanding the changes in the ocular surface microbiome and the impact of various other exposomes may also help to establish the causative factors underlying ocular surface inflammation and scarring, the hallmarks of OSDs. This review provides a summary of the current evidence on exposomes in various OSDs.
Effect of Harvesting Stage and Drying Method on Cowpea Leaf Nutrient Composition

Cowpea leaves are lost annually due to infestation and spoilage when being transported to clients and the losses at the local markets are brought on by inadequate postharvest handling procedures and market glut, particularly during peak seasons. High moisture content from the cowpea leaves at harvest stage may contribute to increased spoilage hence lowering quantity and quality. The choice of appropriate harvesting stage and drying method can help to reduce this problem. The aim of this study was to determine the best harvesting stage and efficient drying method that would maintain high leaf nutrient composition. Cowpeas variety M66 was used for the research and the treatments included three harvesting stages (21, 35 and 49 days after sowing [DAS]), three drying methods (open sun, solar dryer and oven. Data was collected on iron, calcium, crude fibre, beta carotene, protein and moisture content. The data was subjected for variance using Statistical Analysis System 9.2 edition and significantly different means separated using least significant difference at 5%. The results indicated significant (p<0.05) differences in moisture, calcium, proteins, beta carotene and crude fibre content in both trials. Harvest stage and drying method did not significantly (p<0.05) influence the iron content. Oven and solar drying methods showed better nutrient and mineral retention in the three harvesting stages when compared to the open sun drying method.
Effect of insulator layer in graphene plasmonic metamaterials for infrared detection

Graphene is an atomically thin carbon layer with a two-dimensional hexagonal lattice structure and has rich optoelectronic properties well suited to a wide range of applications. Graphene is considered to be a promising material for photodetectors because it exhibits excellent properties such as broadband absorption covering at least the ultraviolet to terahertz frequencies. However, the low optical absorption of graphene, at ca. 2.3%, still remains an important problem. Plasmonic metamaterial structures are good candidates to address this challenge. Metal-insulator-metal-based plasmonic metamaterial absorbers (MIM-PMAs) are highly suitable for the introduction and application of graphene. MIM-PMAs have a multilayer structure that includes plasmonic micropatches, an insulator, and a metal reflector layer. MIM-PMAs exhibit wavelength-selective absorption according to the micropatch size. Our previous research has demonstrated that the optical absorption of graphene is enhanced only by the main plasmonic resonance mode, and the plasmonic resonance modes in MIM-MPAs are strongly influenced by the insulator material. Therefore, the insulator layer plays an important role in graphene-coated MIM-PMAs. In this study, we have investigated the effect of the insulator layer in graphene-covered MIM-PMAs. The graphene was fabricated by chemical vapor deposition and transferred onto MIM-PMAs with different insulator thicknesses. Reflectance measurements demonstrated that varying the insulator thickness had a significant effect on the absorbance of graphene and resulted in modulation of the absorption wavelength. These results indicate that the plasmonic resonance localized at graphene near the plasmonic micropatches is modulated by the waveguide mode in the insulator layer. We believe that the present study will lead to significant improvements in graphene-based infrared detectors.
Perceived Effects of the COVID-19 Pandemic on Loneliness: The Most Vulnerable Population Groups

COVID-19 pandemic lockdown measures reasonably limited the social contacts of people in many countries. It is crucial to understand the effect of such policies on people’s social ties and the possible need for evidence-based public policy amendments. Therefore, this study examines 1) the prevalence of loneliness in the population aged 15+ in Lithuania in late 2021 and 2) the self-rated effect of the COVID crisis on loneliness in population groups with different levels of loneliness. It also focuses on the socio-demographic characteristics of these population groups. Data from a representative cross-sectional quantitative survey (N = 1067), carried out in November–December 2021, was used. Based on the 6-item De Jong Gierveld Loneliness Scale, descriptive statistics analysis revealed the high prevalence (51% of a medium level of loneliness) in the Lithuanian population. One in three people (36%) declared low-level loneliness, and each seventh or eighth (13%) reported high-level loneliness. The feelings of respondents who reported a high level of loneliness were also less stable; they more often stated that their feelings of loneliness increased during the pandemic. These research findings make contributions to studies of loneliness within the context of sudden crises. They emphasise the importance of policymakers focusing on additional measures when preparing for future emergencies and providing special attention to residents who experience the highest levels of loneliness.
ROBUST: A Reliable and Flexible Media Transport for Real-Time Services

In the past few years, accelerated by Covid-19 pandemic, real-time services based on RTC (Real-Time Communications) have become pervasive, and their performance has become critical for a wide range of business and entertainment applications. The diffusion of RTC services beyond controlled enterprise network perimeters poses the challenge of guaranteeing high-quality, reliable, in-time delivery over the Internet and at global, worldwide scale. In this paper, we address such a problem by proposing ROBUST, a Reliable and Flexible Media Transport based on Pub/Sub Information-Centric Networking (ICN) principles. ROBUST brings enhanced reliability and flexibility to RTC applications over varying network environments and conditions. ROBUST initial design is experimentally assessed on three popular Video Conferencing applications (Jitsi Meet, Cisco Webex, and Zoom) with encouraging improvements in terms of objective Quality of Experience (QoE) metrics: e.g., we observe at least 91% loss recovery in the most challenging experimental settings, an improved video smoothness for Zoom up to 160%, a higher resolution for Webex up to 16%, while Jitsi with ROBUST works in conditions where the original application does not.
Data management of digitized indigenous knowledge system in repositories

This paper assesses the data management of digitized Indigenous knowledge systems (IKS) in IKS repositories in South Africa. The study adopted a qualitative research method. The multiple case study research design was adopted to collect data from eight respondents in four Indigenous Knowledge Systems Documentation Centres (IKSDCs) in repositories spread across three provinces in South Africa. The findings revealed that the Department of Science and Technology (DST) coordinates the national IKS programmes under the National Recordal System (NRS) and they are responsible for the management of digitized IKS. The findings also revealed that although the National Indigenous Knowledge Management System (NIKMAS) was built for the management of the data, the system is still in its planning phase, and work is still in progress. In addition, it was discovered that information professionals like archivists and records managers are currently not involved in the management of IKS data in the repositories. The paper offers recommendations on the data management and storage of IKS, data description, mitigating the challenges, and some measures to help ensure the authenticity of the IKS data collected in the repositories.

Building a Lean House With the Theory of Constraints for Construction Operations in Zimbabwe: A Conceptual Framework

The poor performance of construction projects in Zimbabwe, evidenced by cost overruns, extensive delays, reworks, defects, and accidents, has resulted in the need for cost-effective strategies such as the theory of constraints and lean construction (LC). This is because Lean drives out waste, and the theory of constraints (TOC) identifies constraints on which to act to improve performance. By focusing Lean initiatives on construction projects, TOC will lead to better improvements in performance. Although similar studies have been undertaken in other countries, they need to be more contextually relevant due to the myriad of economic challenges synonymous with the Zimbabwean construction industry. A critical review of relevant literature was conducted to observe how TOC allows for identifying constraints hindering progress on construction projects while LC tools would provide solutions. In effect, LC and TOC could reverse poor outcomes of construction operations in Zimbabwe. This conceptual paper thus proposes a framework that identifies constraints using TOC, followed by an evaluation of Lean tools suitable to deal with the identified constraints. The foundation of the lean house will engender effective problem-solving to remove bottlenecks in the design and construction processes.
The pseudo-diffusive phenomenon in photonic crystals with Dirac cones

Pseudo-diffusive phenomenon is an abnormal transmission phenomenon both in electric system and photonic system which hold conical dispersion relations in their band structures. The phenomenon is: near a Dirac point, the transmittance of the system is inversely proportional to the sample’s thickness as if the material was a disordered medium. It is known that in photonic system, Dirac cones can be classified into three different types, which are standard single Dirac cone, double Dirac cones and Dirac-like cone. Some of them can be found either at the center and the corners of the first Brillouin zone. So it raises the questions that: Do the types of the Dirac cones affect the pseudo-diffusive phenomenon? And further, is there any connection between the pseudo-diffusive phenomenon and the locations of the Dirac cones? Through theoretical investigation, we found that the locations of the Dirac cones play a critical role on the pseudo-diffusive phenomenon. If the Dirac cone is located in the center of the Brillouin zone, the pseudo-diffusive phenomenon doesn't exist at the Dirac frequency. Besides, the shapes of the Dirac cones also affect the pseudo-diffusive phenomenon. The non-conical dispersion band of the Dirac-like cone makes the transmission quite different from linear decrease with the increase of the thickness.
