A Design Support Tool Set for Interface Circuits Between Synchronous and Asynchronous Modules

In this paper, we propose a design support tool set for interface circuits between synchronous and asynchronous modules. To facilitate the design of interface circuits between synchronous and asynchronous modules, the proposed tool set generates interface circuits and design constraints based on a predefined communication scheme. In addition, the proposed tool set performs timing verification and delay adjustment to guarantee the operations of the generated interface circuits. In the experiment, we evaluated the latency and overhead of the generated interface circuits. The latency and handshake overhead of the interface circuits generated by the proposed tool set depend on the cycle time of the receiver module. In addition, we designed a system which consists of a synchronous RISC-V processor and an asynchronous multilayer perceptron (MLP) circuit using the proposed tool set. The energy consumption of the system was reduced by 34.0% compared with a system which uses a synchronous MLP circuit.
PROPAGATION IN A HELICAL WAVEGUIDE WITH INHOMOGENEOUS DIELECTRIC PROFILES IN RECTANGULAR CROSS SECTION

This paper presents a rigorous approach for the propagation of electromagnetic (EM) flelds along a helical waveguide with arbitrary proflles in the rectangular cross section. The main objective is to develop a mode model to provide a numerical tool for the calculation of the output flelds, output power density, and output power transmission for an arbitrary step's angle and the radius of the cylinder of the helical waveguide. Another objective is to demonstrate the ability of the model to solve practical problems with inhomogeneous dielectric proflles. The method is based on Fourier coe-cients of the transverse dielectric proflle and those of the input wave proflle. Laplace transform is necessary to obtain the comfortable and simple input-output connections of the flelds. This model is useful for the analysis of dielectric waveguides in the microwave and the millimeter- wave regimes, for difiused optical waveguides in integrated optics. The output power transmission and the output power density are improved by increasing the step's angle or the radius of the cylinder of the helical waveguide, especially in the cases of space curved waveguides. Various methods for the analysis of curved waveguides have been studied in the literature. The propagation of general-order modes in curved rectangular waveguide examined by using asymptotic expansion method (1). A matrix formulation of the generalized telegraphist's equation (2) used to obtain a general set of equations for a guide of arbitrary cross section with curved axis. The matrix elements
Non-Contact Measurement and Identification Method of Large Flexible Space Structures in Low Characteristic Scenes

The end-operation accuracy of the satellite-borne robotic arm is closely related to the satellite attitude control accuracy, and the influence of the vibration of the satellite’s flexural structure on the satellite attitude control is not negligible. Therefore, a stable and reliable vibration frequency identification method of the satellite flexural structure is needed. Different from the traditional non-contact measurement and identification methods of large flexible space structures based on marker points or edge corner points, the condition of non-marker points relying on texture features can identify more feature points, but there are problems such as low recognition and poor matching of features. Given this, the concept of ‘the comprehensive matching parameter’ of scenes is proposed to describe the scene characteristics of non-contact optical measurement from the two dimensions of recognition and matching. The basic connotation and evaluation index of the concept are also given in the paper. Guided by this theory, the recognition accuracy and matching uniqueness of features can be improved by means of equivalent spatial transformation and novel relative position relationship descriptor. The above problems in non-contact measurement technology can be solved only through algorithm improvement without adding hardware devices. On this basis, the Eigensystem Realization Algorithm (ERA) method is used to obtain the modal parameters of the large flexible space structure. Finally, the effectiveness and superiority of the proposed method are verified by mathematical simulation and ground testing.
Ocular trauma, visual acuity related to time of referral and psychosocial determinants, during COVID‑19 pandemic: A prospective study

The aim of the present study was to explore the associations between visual outcomes of ocular injury patients in a tertiary hospital unit with clinical and demographic variables and to evaluate the psychosocial impact of the injury on the patients. An 18-month prospective study of 30 eye-injured adult patients was conducted in the General University Hospital of Heraklion, Crete, a tertiary referral hospital. All severe eye injury case information was prospectively collected between February 1, 2020 and August 31, 2021. Best corrected visual acuity (BCVA) was labelled not poor (>0.5/10 or >20/400 on the Snellen scale, <1.3 in LogMAR scale) and poor (≤0.5/10 or ≤20/400 on the Snellen scale, ≥1.3 on the LogMAR equivalent). Data regarding participants' perceived stress levels, by using Perceived Stress Scale 14 (PSS-14), were collected prospectively, one year after study end. Out of 30 ocular injury patients selected, 76.7% were men and most of them were self-employed and private or public sector workers (36.7%). Not poor final BCVA was related to not poor initial BCVA [odds ratio (OR) 1.714; P=0.006]. No statistical associations were found between visual outcome and demographic or clinical factors, but not poor final BCVA was associated with improved self-reported psychological condition of the sufferers, as examined by a questionnaire sheet developed to collect information for study purpose (8.36/10 vs. 6.40/10; P=0.011). No patient reported job loss or changed work status following the injury. Not poor initial BCVA was a significant predictor for not poor final visual outcomes (OR 1.714; P=0.006). Patients with not poor final BCVA expressed higher levels of positive psychology (8.36/10 vs. 6.40/10; P=0.011) and less fear of eye injury repetition (64.0 vs. 100.0%; P=0.286). Not poor final BCVA was associated with low PSS-14 scores one year after study end (77.3 vs. 0.0%, P=0.003). Collaboration between ophthalmologists, mental health professionals and primary care team may be important in order to help patients to cope with the psychosocial burden sequel to eye trauma.
The Lived Experience of Disability Rights in Ghana: A Case Study from the Eastern Region

This article analyses the struggle for disability rights in Ghana by offering a window into the lived experience of physically disabled Ghanaians in the Akyem Abuakwa traditional area of Ghana’s Eastern Region. Utilizing grassroots narratives of sixteen participants, the article focuses on the themes of financial and social support to illuminate the challenges facing disabled individuals in a peri-urban area of Southern Ghana. The analysis engages with the concept of Ubuntu, which focuses a lens on traditional African community as a natural and inherently good vehicle for social inclusion. Using the idea of community as a frame of reference, we present a brief historical overview, followed by data from sixteen interviews to explore the connection between socio-economic change, community dynamics and disability rights. We conclude by arguing that the data raises questions about the revival of traditional communal bonds as a solution to social exclusion produced by disability.
The Application of RGB, Multispectral, and Thermal Imagery to Document and Monitor Archaeological Sites in the Arctic: A Case Study from South Greenland

Over the past decades, climate change has accelerated the deterioration of heritage sites and archaeological resources in Arctic and subarctic landscapes. At the same time, increased tourism and growing numbers of site visitors contribute to the degradation and manipulation of archaeological sites. This situation has created an urgent need for new, quick, and non-invasive tools and methodologies that can help cultural heritage managers detect, monitor, and mitigate vulnerable sites. In this context, remote sensing and the applications of UAVs could play an important role. Here, we used a drone equipped with an RGB camera and a single multispectral/thermal camera to test different possible archeological applications at two well-known archaeological sites in the UNESCO World Heritage area of Kujataa in south Greenland. The data collected were used to test the potential of using the cameras for mapping (1) ruins and structures, (2) the impact of human activity, and (3) soil moisture variability. Our results showed that a combination of RGB and digital surface models offers very useful information to identify and map ruins and structures at the study sites. Furthermore, a combination of RGB and NDVI maps seems to be the best method to monitor wear and tear on the vegetation caused by visitors. Finally, we tried to estimate the surface soil moisture content based on temperature rise and the Temperature Vegetation Dryness Index (TVDI), but did not achieve any meaningful connection between TVDI and on-site soil moisture measurements. Ultimately, our results pointed to a limited archaeological applicability of the TVDI method in Arctic contexts.
Three-dimensional extended nonlocal photopolymerization driven diffusion model. Part II. Photopolymerization and model development

In Part I of this paper [J. Opt. Soc. Am. B31, 2638 (201410.1364/JOSAB.31.002638JOBPDE0740-3224)], an absorption model is used to predict the dye concentration and light intensity distribution inside a photopolymer medium volume. These results are now used as inputs to a Runge–Kutta algorithm acting as a subgrid of the finite-difference time-domain (FDTD) method. In this way, a full 3D time-dependent nonlocal photopolymerization driven diffusion model is implemented. This enables a more accurate and physical description of the evolutions of the holographic grating. The validity of the proposed model is examined by applying it to fit experimental data for acrylamide/polyvinyl alcohol photopolymer material layers containing the photosensitizer erythrosine B. Material parameter values are estimated by numerically fitting the experimentally obtained refractive index modulation growth curves and angular scans.
Insights from COVID-19: Reflecting on the Promotion of Long-Term Health Policies in China

China announced the Healthy China Initiative (2019–2030) in 2019, an action program aimed to support the country’s current long-term health policy, Healthy China 2030, which focuses on public health promotion and health awareness. Following the implementation of the policy, China had the COVID-19 pandemic, which had an influence on both the public’s degree of health awareness and the adoption of the HCI. This research examines whether the COVID-19 epidemic has increased public understanding and acceptance of China’s long-term health policy. In addition, it analyzes whether the Chinese public’s awareness of health policy has been impacted by China’s usage of smart healthcare in its response to the pandemic. To correspond to these study aims, we used a questionnaire based on the research questions and recent relevant research. The results of the study, based on an examination of 2488 data, demonstrate that the Healthy China Initiative is still poorly understood. More than 70% of respondents were unfamiliar with it. However, the results imply that respondents are becoming more aware of smart healthcare and that public acceptance of official health policies can be aided by the sharing of knowledge about this. As a result, we examine the situation and draw the conclusion that the spread of cutting-edge health-related technology can enhance the communication of health policy and provide participants and policymakers with fresh insights. Finally, this study also can provide lessons for other countries in the early stages of policy dissemination, particularly health policy advocacy and promotion during epidemics.
Magnetic field, reconnection, and particle acceleration in extragalactic jets

Extra-galactic radio jets are investigated theoretically taking into account that the jet magnetic field is dragged out from the central rotating source by the jet flow. Thus, magnetohydrodynamic models of jets are considered with zero net poloidal current and flux, and consequently a predominantly toroidal magnetic field. The magnetic field naturally has a cylindrical neutral layer. Collisionless reconnection of the magnetic field in the vicinity of the neutral layer acts to generate a non-axisymmetric radial magnetic field. In turn, axial shear-stretching of reconnected toroidal field gives rise to a significant axial magnetic field if the flow energy-density is larger than the energy-density of the magnetic field. This can lead to jets with an apparent longitudinal magnetic field as observed in the Fanaroff-Riley class II jets. In the opposite limit, where the field energy-density is large, the field remains mainly toroidal as observed in Fanaroff-Riley class I jets. Driven collisionless reconnection at neutral layers may lead to acceleration of electrons to relativistic energies in the weak electrostatic field of the neutral layer. A simple model is discussed for particle acceleration at neutral layers in electron/positron and electron/proton plasmas.

A method for calculating the dynamic characteristics of switched reluctance motor (SRM) has been proposed. The inductance model of SRM that is changed following the rotor position can be estimated from FEM analysis. Based on the model, we design a circuit simulation of SRM using SPICE, which can simulate voltages, currents, torque and rotation speed of the SRM.

The firm-level employment impact of COVID-19: International evidence from World Bank Group’s Enterprise Surveys

ABSTRACT Using new data from the World Bank Group’s COVID-19 Impact Follow-up Enterprise Surveys completed in 39 countries, we find that a firm’s pre-pandemic financial condition is an important predictor of employment but only at the onset of the pandemic. Second, firms with teleworking arrangements, furloughed workers, and temporarily closed or reporting a decreased demand for products/services are more likely to reduce their workforce at extensive and intensive margins. We also found a clear effect of gender on employment. Firms with a majority of female workers are more likely to reduce their workforce than firms with a majority of male workers.
Teacher’s Perspectives on the Representation of Children with Special Educational Needs in Irish-Medium Contexts

This research study explores teacher’s perspectives on the level of representation of children with special educational needs (SEN) in Irish-medium schools. In recent years, there has been a significant rise in demand for Irish-medium education. (Gaeloideachas, 2020). An Chomhairle um Oideachas Gaeltachta agus Gaelscolaíochta (COGG) reported that there were 50,000+ children and young people enrolled in Irish-medium education in 2010. According to Gaeloideachas.ie (2020), the percentage of pupils attending Gaelscoileanna in the Republic of Ireland reached a record level in the academic year 2018/2019. In the context of these statistics, the researcher posed the following question: if there are 50,000+ children being educated through the medium of Irish, what is the level of representation of children with SEN within this figure? This research study investigates, through the eyes of primary Irish-medium teachers, the level to which children with SEN are represented in Gaelscoileanna. Are they under-represented, equally represented, or over-represented? Additionally, this study questions what the level of representation means for the pupils, the teachers, the school, and the parents of children with SEN.
A Diagnostic Study of the Dynamics of the Northern Hemisphere Winter of 1985‐86

February 1986 was notable for a dramatic blocking pattern in the eastern N Atlantic with part of NW Europe having its coldest February in 300 years. However, the previous December and January had been mild in the same region and the hemispheric anomaly field was characterized by a pattern which could be viewed as a wave-train emanating from the tropical western Pacific. Such an extreme change within a single winter season is unusual and must be understood if reliable monthly and seasonal forecasts are ever to be produced. The tropospheric flow field, isentropic distributions of potential vorticity, and diabatic heating calculated as a residual in the thermodynamic equation are used to illustrate the similarities and differences in the two parts of the winter and to suggest possible reasons for these differences. the mean vorticity equation is also used to investigate the importance of the change in the zonal flow, the transients and the mean divergence. It is concluded that the change in the fluxes due to the synoptic weather systems was crucial, but that a catalyst for the February block could have been provided by an unusual diabatic forcing in the S American-Caribbean region. Implications are drawn for the ingredients which must be included in dynamical models for predicting on the monthly to seasonal time-scales.
Transient analysis of LE‐VGF growth of compound semiconductors

A finite difference simulation for the bulk single crystal growth of indium phosphide by the liquid encapsulated vertical gradient freezing (LE‐VGF) method with a flat bottom crucible is presented. In order to treat a curvature interface, the boundary fixing method is applied. The transient behavior of the flow and temperature fields, the melt/crystal interface shape and the growth rate during growth are studied numerically. The crystal growth rate is not constant although the temperature lowering rate is constant. The effect of crucible thickness, thermal conductivity of the crucible and temperature of the growth furnace wall on the crystal growth behavior are discussed.
The role of social group influences when intending to purchase premium alcohol

Abstract This study investigates the effect that social group influences have on the purchase intention of premium alcohol by adapting the theory of planned behaviour. The moderating effect of the need to save face and conform to a social group’s expectations on the purchase intention of premium alcohol is explored. Data was collected using questionnaires, with 251 responses analysed using the PLS-SEM. The results show that attitude and subjective norms have a positive and significant impact on the purchase intention of premium alcohol, while perceived behavioural control does not. Brand consciousness and status consumption were found to have an impact on attitude and subjective norms respectively, with status consumption revealing the strongest relationship. This study offers insight to both researchers by understanding the impact of social influences and to premium alcohol brands that would be able to further enhance their marketing strategies and resonate with consumers in a highly competitive environment.
Another Student´s T-test : Proposal and evaluation of a modified T-test

In this paper we propose a way of performing hypothesis tests by utlizing all information that we know under the null hypothesis. W.S. Gosset, also known as Student, derived the famous Student’s T-test in the early days of the twentieth century and this is where this paper departures from. It turns out that when using Student’s T-test we are not using all available information that is known under the null hyptothesis. By using all known information we can get a better variance estimator than the usual variance estimator. The test based on this variance estimator is in this paper called Another Student’s Test (AST). The test is evaluated with the use of simulation and compared to Student’s T-test. The conclusion that we arrived at were that AST and Student’s T can not be said to perform any different, at least not under the settings used in this paper. Albeit this, further analysis should be carried out to investigate AST further, and a couple of situations where the ideas can be used are proposed. Table of contents
Spatio-temporal filament behaviour in a dielectric barrier discharge plasma actuator

The behaviour of filaments in a dielectric barrier discharge plasma actuator in atmospheric air has been visualized through high-speed framing photography. A filament is recognized by its radiation emission in the positive, ascending phase of an applied ac voltage (1–5 kV, 1–5 kHz). A current pulse appears with a random time-interval typically of the order of 10 µs. A filament appears at a different location almost randomly in the span on the dielectric sheet, while the radiation distribution that is averaged over a couple of ac oscillation periods is quite uniform. With shortening of the framing interval, the lifetime of a single filament is found to be of the order of 10 ns.
