Ultrathin ring-shaped metasurface for a multiview 3D display
Authors: Ahmad Munzza , Li Jingnan , Zhou Ruyi , Sun Yutong , Liu Juan 
Published: June 2024

The development of glasses-free 3D multiview displays has opened up new avenues for
experiencing 3D displays. Multiview technologies have the advantages
of visual discomfort alleviation, smooth motion parallax, full-color
display, and broad depth of focus. However, their intended uses are
impeded due to the versatility of designing ultrathin display systems
freely by using metasurface technology. This paper presents a
technique for creating an ultrathin ring-shaped metasurface for a
multiview display system with a thickness of 2 µm. The proposed
multiview 3D display system generates eight views. Numerical
simulations are used to confirm the efficacy of the suggested
strategy, and the results demonstrate the attainment of a high-quality
multiview 3D display. The proposed work demonstrates the potential
applications of the metasurface in multiview display systems for
electromagnetic wave manipulation in future 3D TVs, imaging,
integrated optics, and next-generation compact displays.
Light Wave to PhotoWave vs
Photoelectric Effect to PhotoWave Effect
Authors: Peng Hui 
Published: June 2024

Feynman (1956) called the double slit experiment "a phenomenon […] has in it the heart of quantum mechanics. In reality, it contains the only mystery. We cannot make the mystery go away by ‘explaining’ how it works". To study the mystery, the double slit experiments were performed one photon at the time. The photons are described by probability wave function. To interpret, the concept of the collapse of the wave function is utilized. However, the collapse of the wave function leads to the inconsistent/incomplete of the quantum mechanics (Penrose, 2022). In this article, we propose Postulate: the diaphragm, e.g., the slide of the double slit, does not change the nature of the light passing through it. Then we perform multi-experiments to test Postulate, and show that, before and after passing the diaphragm of the double slit, the light is photons. It is photons that produce the wave pattern, e.g., the interference pattern. We referred the phenomena as “PhotonWave Phenomena”.
Particle phenomena	Wave phenomena
Light as wave	non	Light waves produce wave patterns
Light as photons	Photons produce ejection of electrons:
Photoelectric effect	Photons produce wave patterns:
PhotoWave phenomena
A complete interpretation should consistently explain all of the experiments, which challenges the existing wave theories. The experiments show the coexistence of particle nature and wave pattern in the same experiment, which violate Bohr’s complementarity principle and the wave interpretations. The experiments provide the comprehensive phenomena for developing theoretical model to study the nature of the light, the complementarity principle, the wave-particle duality, and wave theories.

Introduction
Depression is one of the most common psychiatric disorders, affecting approximately 60% of people infected with the human immunodeficiency virus (HIV). Low and middle-income countries (LMICs), including Ethiopia, bear a disproportionate burden of depression among HIV/AIDS patients. Several factors, including perceived stigma, have been linked to increased depression among HIV/AIDS patients. Therefore, we aimed to estimate the pooled effect of perceived stigma on depression among HIV/AIDS patients in Ethiopia.

Methods
For this systematic review and meta-analysis, we systematically retrieved all relevant studies starting from January 1, 2000 to June 1, 2022 from PubMed, HINARI, and Google Scholar. This review included observational studies that reported the effect of perceived stigma on the prevalence of depression among HIV-positive adults in Ethiopia. The effect estimate of the pooled effect of perceived stigma on depression was conducted using DerSimonian-Laird’s random effect model using STATA/MP version 16. An adjusted odds ratio (AOR), along with a 95% confidence interval (CI), was conducted to estimate the strength of the association between perceived stigma and depression.

Results
Eleven studies with a total of 4,153 HIV-positive adults were included for meta-analysis. The results of the meta-analysis revealed that the odds of depression were higher among patients with perceived stigma (AOR: 3.78, 95% CI: 2.73, 5.24). The pooled prevalence of depression among HIV/AIDS patients in Ethiopia was 39% (95% CI: 32%, 46%) (I2 = 98%, p ≤ 0.0001). The subgroup analysis revealed that the primary studies conducted in the Oromia region had the highest pooled prevalence of depression at 48% (95% CI: 32%, 63%).

Conclusion
The pooled estimates of the meta-analysis revealed that perceived stigma and depression were strongly associated. Stigma and depression screenings should be carried out for additional treatments and prevention, and programs supporting Ethiopia’s PLWHA population should be strengthened.
Empowering parents to optimize feeding practices with preschool children (EPO-Feeding): A study protocol for a feasibility randomized controlled trial
Authors: Wang Jian , Cao Yang , Wei Xiaoxue , Winkley Kirsty , Chang Yan-Shing 
Published: June 2024

Background
Parental feeding practices (PFPs) play a key role in fostering preschoolers’ dietary habits and in mitigating the risk of childhood obesity. Nevertheless, parents often employ inappropriate feeding practices, leading to children’s potential nutrition-related issues. Thus, research is needed to inform interventions that focus on optimizing feeding practices.

Methods
This protocol describes the evaluation of a novel intervention—Empowering Parents to Optimize Feeding Practices (EPO-Feeding Program). The program will be evaluated with a two-arm feasibility randomized controlled trial (RCT) in Yangzhou, China. The program includes four weekly group-based training sessions led by healthcare professionals for parents of preschool children. The intervention incorporates sessions, group discussions, motivational interviewing, and supplementary materials (e.g., key messages and educational videos) aimed at enhancing parents’ knowledge, skills, and behaviours related to feeding practices. The primary outcomes include i) implementation feasibility, primarily assessed through retention rates; and ii) program acceptability through a survey and qualitative process evaluation. Secondary outcomes encompass the potential impacts on i) PFPs, ii) parental perception of child weight (PPCW), iii) parenting sense of competence, iv) children’s eating behaviours, and v) child weight status. Quantitative analyses include descriptive estimates for evaluating the feasibility and linear mixed regression analysis for testing the potential effects. Qualitative valuation will use thematic framework analysis.

Discussion
If this study shows this program to be feasible to implement and acceptable to parents, it will be used to inform a fully powered trial to determine its effectiveness. The research will also help inform policy and practices in the context of child nutrition promotion, particularly regarding implementing group-based training sessions by healthcare providers in similar settings.

Patient experiences with value-based healthcare interventions at the HIV outpatient clinic of the Erasmus Medical Centre
Authors: van Hoorn Evelien S. , Bassant Nadine Y. , Lingsma Hester F. , de Vries-Sluijs Theodora E. 
Published: June 2024

Background
One of the aims of value-based healthcare (VBHC) is to deliver more patient-centred care. However, little is known about the effect of VBHC interventions on patient experiences. We aim to explore how patients experience VBHC as implemented in an HIV outpatient clinic in an academic hospital in the Netherlands.

Methods
The HIV outpatient clinic of the Erasmus MC, Rotterdam, the Netherlands, an academic tertiary hospital, implemented a VBHC intervention consisting of 1) implementation of a generic quality of life questionnaire, administered before each visit, 2) a change in consultation schedule; from twice a year face-to-face to one face-to-face double consultation and one remote consultation per year, and 3) a change in consultation structure; from a single face-to-face consultation with the infectious diseases (ID) specialist to a double consultation in which the patient visits both the nurse and the ID specialist. Semi-structured interviews were held with Dutch or English-speaking adult patients, that had been a patient within Erasmus MC for more than 5 years, on their experiences with the implemented changes.

Results
Thirty patients were interviewed. Patients had no objections towards completing the questionnaires especially if it could provide the professionals with additional information. Patients were primarily positive about the change in consultation schedule. For the yearly remote consultation they preferred a telephone-consultation above a video-consultation. The change in consultation structure ensured that more topics, including psychosocial and medical aspects could be discussed. Some patients did not see the added value of talking to two professionals on the same day or completing the quality of life questionnaire before their consultation.

Conclusion
Patients are generally positive towards the VBHC interventions implemented at the HIV outpatient clinic. Our findings may inform further optimization of VBHC interventions and improve patient-centred care in outpatient HIV clinics.

O objetivo desse trabalho foi descrever acidentes com animais peçonhentos em áreas urbanas e a sua relação com a saúde pública. Para a presente revisão bibliográfica foi realizada uma busca de publicações com ênfase no período de 2003 a 2021 em bancos de dados relacionados à saúde pública e em sites oficiais da internet. Entende-se que existe um profundo interesse médico e de saúde pública sobre animais peçonhentos e acidentes que são acometidos por eles e seus riscos iminentes a saúde. Além disso, o interesse médico envolve a produção de fármacos relacionados a esses animais, como o próprio soro específico para o tratamento do envenenamento. A prevenção desses acidentes envolve ações como: evitar desmatamento, queimadas e exploração do meio em que vive os animais. Cabe salientar que existe uma diferença entre animais peçonhentos e animais venenosos, sendo os peçonhentos os que possuem a capacidade de inocular a toxina através de uma presa ou ferrão, enquanto os venenosos, como os sapos, possuem a toxina em sua pele, sendo inoculado ao serem ingeridos ou tocados.

Published: June 2024

Abstract
Quasi-bound states in the continuum (quasi-BICs) offer unique advantages in enhancing nonlinear optical processes and advancing the development of active optical devices. Here, the tunable robust quasi-BICs resonances are experimentally achieved through the engineering of multiple-hole Si-metasurface. Notably, the quasi-BICs mode exhibits flat bands with minimal dispersion at a wide range of incident angles, as demonstrated by the angle-resolved spectroscopy measurements. Furthermore, we demonstrate a giant second-harmonic generation (SHG) enhancement by coupling a WSe2 monolayer to the quasi-BICs hosted in the metasurface. Leveraging the strong local electric field and high state density of the observed quasi-BICs, the SHG from the WSe2 monolayer can be enhanced by more than two orders of magnitude. Our work paves the way for effectively enhancing nonlinear optical processes in two dimensional (2D) materials within the framework of silicon photonics and is expected to be applied in nonlinear optical devices.
Shape unrestricted topological corner state based on Kekulé modulation and enhanced nonlinear harmonic generation

Published: June 2024

Abstract
Topological corner states have been extensively utilized as a nanocavity to increase nonlinear harmonic generation due to their high Q-factor and robustness. However, the previous topological corner states based nanocavities and nonlinear harmonic generation have to comply with particular spatial symmetries of underlying lattices, hindering their practical application. In this work, we design a photonic nanocavity based on shape unrestricted topological corner state by applying Kekulé modulation to a honeycomb photonic crystal. The boundaries of such shape unrestricted topological corner state are liberated from running along specific lattice directions, thus topological corner states with arbitrary shapes and high Q-factor are excited. We demonstrate enhancement of second (SHG) and third harmonic generation (THG) from the topological corner states, which are also not influenced by the geometry shape of corner. The liberation from the shape restriction of corner state and nonlinear harmonic generation are robust to lattice defects. We believe that the shape unrestricted topological corner state may also find a way to improve other nonlinear optical progress, providing great flexibility for the development of photonic integrated devices.
Estimation of monotone α-quantile of past lifetime function with application
Authors: Kayid Mohamed 
Published: June 2024

Abstract
In many physical situations, it is reasonable to assume that the α-quantile of past life functions is increasing. In this study, we propose a new estimator for an increasing α-quantile of the past life function for right-censored data. We investigate the asymptotic properties of the new estimator and explore its weak and strong convergence. The simulation results show that the new estimator is consistent and outperforms the usual estimator from the literature. As an illustrative example, a time event from a data set of the Mayo Clinic study on primary biliary cirrhosis was analyzed.
Asymmetric Pricing Caused by Collusion
Authors: Obradovits Martin 
Published: June 2024

Abstract
In many markets, empirical evidence suggests that positive production cost shocks tend to be transmitted more quickly and fully to final prices than negative ones. This article explains asymmetric price adjustment as caused by firms imperfectly colluding on supra-competitive price levels. I consider an equilibrium in which positive cost shocks are transmitted instantaneously, whereas downward price adjustments only occur once aggregate market demand turns out unexpectedly low. This equilibrium exists whenever demand is sufficiently stable and negative cost shocks are not too large.

Abstract
This paper presents laboratory investigations on the vertically drilled borehole specimens belonging to the Barren Measure Formation shales in the Raniganj sub-basin, India. These shales were examined for their mineralogical makeup and geomechanical properties through a series of laboratory experiments viz. X-ray diffraction, uniaxial tests, single-stage triaxial tests, tensile strength tests, porosity, and permeability measurements. The mineralogical assessment has revealed dominant clay minerals and moderate silica content. The mechanical tests yielded a high Young’s modulus and low Poisson’s ratio in these shales with brittle to semi-brittle type of failure. The compositional, elastic and tensile brittleness of these shales indicate values that are in good agreement with the brittle nature of gas shales. Furthermore, these shales report low porosity and ultra-low permeability. The Barren Measure Formation in the Raniganj sub-basin is organically rich and was targeted during India’s first exploratory well, yielding natural gas. However, these shales are still in their infancy in terms of their geomechanical attributes. This study also attempted to generate basic data on properties like compressibility, elastic moduli, and tensile strength, which are among the critical parameters controlling the reservoir simulation program. The results of brittleness and failure parameters (elastic moduli, internal friction angle, cohesion, compressive strength and tensile strength) of Barren Measure Formation in Raniganj sub-basin of Damodar Basin, India show high similarity with those of Roseneath Formation in Cooper Basin, Australia revealing their analogous origin.
Integration of Geological and Geophysical Approaches in Meeting the Challenges of Uranium Exploration in the Cuddapah Basin — a Case Study from Chitrial Area, Nalgonda District, Telangana

Published: June 2024

Abstract
Uranium exploration in the Cuddapah Basin is both scientifically and logistically challenging. An integrated multidisciplinary approach is adopted to infer the subsurface geology. Very Low Frequency Electromagnetic (VLF-EM) survey, conducted over parts of Chitrial outlier, Nalgonda district, Telangana, has indicated thirteen subsurface conductors. Two prominent trends, viz. NE-SW and NNE-SSW/N-S, are revealed from the stacked profiles and pseudosections. Six of these conductors (2 NE-SW and 4 NNE-SSW/N-S trending) are found to have appreciable strike extent (&gt;300 m) with steeply dipping (60°–75°) to vertical attitude. These conductors are interpreted to extend ≥75 m into the basement from the overlying sediments. The ballooned-up zones of low apparent resistivity especially in the sediments, associated with one NNE-SSW/N-S and two NESW trending conductors, are interpreted as zones of hydrothermal alteration and, therefore, demarcated as potential targets for subsurface exploration by inclined boreholes.
This study indicates that integration of geophysical data with geological features will help in optimizing the exploration input and narrowing down the target zones for uranium exploration even in deeper reaches of the Cuddapah Basin.

Published: June 2024

Abstract
Haryana is one of the dominant agrarian states of India but salinity in the groundwater is one of the major concerns in the state. The salinity in groundwater is observed from top itself in the central part of Haryana consisting of Hisar, Jind, Rohtak, and Jhajjar districts. As a result, local inhabitants are facing severe problems with the nonavailability of fresh drinking water. In some places, shallow aquifers are having marginally saline water which is used by the local inhabitants in dry months. Groundwater even in shallow aquifers also becomes saline due to less rainfall and intrusion of saline water from lower layers. In some areas, the thickness of freshwater columns has been reduced significantly due to the excessive withdrawal of fresh water and intrusion from underlying saline groundwater aquifers. It is therefore pertinent to study fresh/saline groundwater interface to solve these problems on scientific basis. The geophysical methods especially electrical resistivity method has proved very useful for the estimation of fresh/ saline groundwater interface. The present paper deals with the findings of electrical resistivity survey conducted in Adampur and Agroha blocks of district Hisar, Haryana, India. Thirty-five Vertical Electrical Soundings (VES) were conducted in these areas for this purpose. The results indicate that the entire study area is occupied with marginally saline to highly saline groundwater. The study shows the presence of a thin layer of marginally saline groundwater almost uniformly distributed in the entire study area.

Published: June 2024

Abstract
Earlier, prior to Holocene, after its avulsion from the west of Aravali to the east of Aravali, the Yamuna River was flowing in a straight course in N-S direction, remaining ~5-25 km closer to the Indian peninsula in comparison to its active channel. The river, between Delhi and Agra, has shifted to its present location after taking an eastward turn at south of Delhi followed by a southward turn. There are geomorphic, lithologic and hydrogeologic imprints of its palaeo-courses in the left-back palaeo-valleys (width: 10-15 km) in the Marginal Alluvial Plain (MAP) between the aforesaid cities. Granular zones (up to 60 m thick), comprising fine to medium, micaceous grey sand, are preserved in the top 70 m slice of the stratigraphic framework along the palaeochannels. The sand zones create promising hydrogeological conditions in otherwise an aquifer-scarce region of MAP. The palaeochannel belt runs for almost 180 km being roughly parallel to the active course. Frequent imprints of the palaeochannels are observed between Delhi and Mathura in a length of ~120 km. The saturated palaeochannel aquifer bears the potential of yielding 7.6 BCM of fresh groundwater.
