Mutual-Coupling Reduction of a Quad-Port Cross-Slot Antenna With Simultaneously Co-Polarized and Dual-Polarized Patterns

In this article, a novel design concept for bandwidth enhancement and mutual-coupling (MC) reduction of a single quad-port cross-slot antenna with simultaneously co-polarized and dual-polarized radiation patterns is proposed and designed. Initially, the first-, second-, and third-order modes (CM1–CM3) of a dual-port single-slot antenna with co-polarized pattern are theoretically studied by using a characteristic mode analysis (CMA). The results demonstrate that when one port is excited, the electric-field null of the antenna could be shifted to another unexcited port by combining these three modes, thus reducing the MC between two ports under a co- polarized pattern. Then, the short-ended bridges are loaded across the slot, resulting to move resonant frequencies of its CM1–CM3 closely to each other. After that, the microstrip lines are selected to excite the slot antenna for wide impedance matching. In addition, the linear slot is bent in order to reduce the electrical length. With these arrangements, our proposed quad-port cross-slot antenna has gained the desired co- polarized and dual-polarized radiation patterns with low MC. Finally, our designed antenna prototype is fabricated and measured. The results indicate that the isolation bandwidth ( $\vert S_{11}\vert < -10$ dB and MC $ < -17$ dB) of our designed antenna is successfully extended to about 16.18% ranging from 4.83 to 5.68 GHz, becoming obviously widened compared to the traditional counterpart. Most importantly, both co- polarized and dual-polarized radiation patterns are independently realized under four ports while holding single layer, small thickness, single element, and stable radiation pattern simultaneously.
Disrespect and abuse of women during childbirth in selected health facilities in Sokoto metropolis, Nigeria

Background: The promotion of respectful care during delivery is of utmost importance if the goals of attainment of quality health care and utilization of skilled birth attendants in our health facilities are to be achieved. This study sought to assess the prevalence, forms, and factors associated with Disrespect and Abuse (D&A) of women during childbirth in Sokoto metropolis of Sokoto state. Method: A descriptive cross-sectional design was used to study 290 women who had facility-based delivery within the past eight weeks in Sokoto metropolis and were attending childhood immunization or family planning clinics. Data was collected using a set of structured questionnaire and was analyzed using IBM SPSS version 23 computer software. Level of statistical significance was set at p<0.05 and approval for the study was obtained from the Research Ethics Committee of Usmanu Danfodiyo University Teaching Hospital, Sokoto while written informed consent was obtained from respondents after explaining the objectives of the study to them. Results: A total of 57 (19.7%) of the respondents had experienced at least one form of D &A with bad attitude accounting for 75.4%, followed by Physical abuse (50.9%). Nurses and Midwives ranked highest (78.9%) among the perpetrators of D&A. Emotional distress, injury and death of baby were some of the negative effects of D&A. Conclusion: The incidents of D&A have wider implications for the utilization of maternity services and maternal mortality. There is an urgent need for the training and re-training of health workers about respectful maternity care in Nigeria.
Integral Use of Red Wine Pomace after Hydrostatic High Pressure: Application of Two Consecutive Cycles of Treatment

The influence of applying hydrostatic high pressure (HHP) to red grape pomace cv. Tempranillo was studied to obtain an ingredient rich in bioactive compounds for the manufacture of food products. Four treatments were investigated: (i) 600 MPa/1 s; (ii) 600 MPa/300 s, and other two treatments with 2 cycles of HHP: (iii) 2 cycles of 600 MPa/1 s; and (iv) 1 first cycle of 400 MPa/1 s and a second cycle 600 MPa/1 s. Treated pomace was stored at different temperatures (4 and 20 °C). The application of two consecutive cycles had no effect on the microorganisms’ inactivation compared to only one cycle. Immediately after HHP, the phenolic compounds content was maintained. However, HHP had no influence on the polyphenol oxidase enzyme (PPO), and so the phenolic compounds were significantly reduced during storage. Hence, the shelf-life of red grape pomace was significantly reduced at both temperatures, although phenolic compounds were better preserved under refrigeration than at room temperature.
The e⁄ect of family background on children+ sl e vel of schooling attainment in Spain

This paper provides microeconomic estimates of the role played by family background in determining children’s level of schooling attainment in Spain. We use an ordered logit model to explore the eA ects of family background and other supply factors on the probability of various educational outcomes. Our estimates are based on household data obtained from the ECVT , L iving and Working Conditions Survey (Ministerio de EconomoÂ a y Hacienda, 1985), a Spanish nation-wide household survey conducted at the end of 1985. In general, and given the Spanish capital constraints, parental income, social class, and family size, explain children’s level of schooling. These results are consistent with those of the literature that focuses on the role of family background in determining schooling attainment. I. ANALYTICAL CONSIDERATIONS This paper studies the diA erences in educational attainment in terms of parents’ decisions about their children’s education. We apply the Becker model presented in A T reatise on the Family (Becker, 1991) and our empirical work is a contribution to the literature that focuses on the role of family background in determining schooling, originated in Behrman et al. (1980). We use microdata set taken from a representative survey of the Spanish living and working conditions (ECVT survey, Ministerio de Economo a y Hacienda, 1985). Duringtheearly 1960s,educationwasthought to be not only a very notable source of economic growth, but also an important instrument in reducingsocial inequalities. However, in the late 1970s it began to be seriously considered that educational bene® ts, in general, are best utilized by those who come from better positioned family backgrounds. Therefore, equality of educational opportunitywill notpresumablyleadtothe desired
The intention of university students to donate at zakat institution through digital payment

In addition to the UTAUT2 model, this study adds brand awareness and perceived security as independent variables.
Deep Visual Sharing With Colorblind

Visual sharing between color vision deficiency (CVD) and normal-vision audiences is challenging due to the need of simultaneous satisfaction of multiple binocular visual requirements, in order to offer a color-distinguishable and binocularly fusible visual experience to CVD audiences, without hurting the visual experience of the normal-vision audiences. Existing methods enable the feasibility of visual sharing but are not quite suitable for practical usage due to their instable and time-consuming optimization nature. In this paper, we propose the first deep-learning based solution for solving this visual sharing problem. Our method outperforms the existing solution in terms of all evaluation metrics. To achieve this, we propose to formulate this binocular image generation problem as a generation problem of a difference image, which can effectively enforce the binocular constraints. We also propose to retain only high-quality training data and enrich the variety of training data via intentionally synthesizing various confusing color combinations. With these, we train up a high-quality neural network model. Through multiple quantitative measurements and user study, we demonstrate this learning-based approach can significantly improve the quality of generated results with fast performance.
REGARD: A new GNSS‐based real‐time finite fault modeling system for GEONET

The short‐period seismometer‐based magnitude saturation problem, especially for events with magnitude > 8, can be improved by a real‐time Global Navigation Satellite System (GNSS) positioning technique, which has enabled rapid estimation of a finite fault model for a large earthquake without any saturation. A new real‐time fault modeling system based on the GNSS Earth Observation Network (GEONET) is developed and is under experimental operation in Japan. In this paper, we present the newly developed system REGARD (the Real‐time GEONET Analysis system for Rapid Deformation monitoring), which consists of real‐time GNSS positioning, automatic detection of coseismic displacement by the event, and quasi real‐time finite fault model inversion routines. The performance of the automatic event detection system is tested through experimental real‐time operation based on GEONET data for 2 months. Furthermore, we also test the reliability of the finite fault model inversion routines using real raw GNSS data observed for past large earthquakes: the 2003 Tokachi‐oki earthquake (moment magnitude (Mw) 8.3), the 2011 Tohoku earthquake (Mw 9.0), and the 2011 off‐Ibaraki earthquake (Mw 7.7). A simulated 1707 Hoei‐type Nankai Trough earthquake (Mw 8.7) is also tested. The real‐time experimental operation shows that real‐time GNSS positioning is precise enough to detect all the tested earthquakes, and the inversion results demonstrate that the REGARD can reliably estimate the earthquake size and its extent within 3 min after the origin time. These results suggest that the REGARD system will complement the seismometer‐based magnitude determination system.
Boussinesq modeling of wave‐induced hydrodynamics in coastal wetlands

In this paper, an improved formulation of the vegetation drag force, applicable for the fully non-linear Boussinesq equations and based on the use of the depth varying, higher order expansion of the horizontal velocity, in the quadratic vegetation drag law has been presented. The model uses the same numerical schemes as FUNWAVE TVD but is based on the CACTUS framework. The model is validated for wave height and setup, against laboratory experiments with and without vegetation cover. The wave attenuation results using the improved formulation were compared with those using the first order reference velocity as well as with analytical solutions using linear wave theory. The analytical solution using the depth varying velocity, predicted by the linear wave theory, was shown to match the model results with the fully expanded velocity approach very well for all wave cases, except under near emergent and emergent conditions (when the ratio of stem height to water depth is greater than 0.75) and when the Ursell (Ur) number is less than 5. Simulations during peak storm waves, during Hurricane Isaac, showed that vegetation is very effective in reducing setup on platforms and in reducing the wave energy within the first few hundred meters.
Anti-inflammatory activity of An Ethanol Extract of Pucuk Merah (Syzigium myrtifolium Walp.) in vivo

Compared with classical Utilization of medicinal plants with anti-inflammatory properties, it needs to be done to find alternative treatments with relatively more minor side effects, such as Syzygium myrtifolium walp. This study aims to determine the effective dose of ethanol extract of pucuk merah as an anti-inflammatory in 30 male white rats of the Wistar strain. Testing the extract's anti-inflammatory effect was measured by measuring the edema volume on the soles of the rats' feet after being induced with 1% carrageenan with a pletismometer. The test animals were divided into six treatment groups, namely group 1 negative control (Na CMC 1%), group 2 positive control (Na Diclofenac 50 mg/KgBW), group 3 (dose of pucuk merah leaves extract 75 mg/KgBW), group 4 (quantity of pucuk merah leaves extract 100 mg/kgBW), and group 5 (amount of pucuk merah leaves extract 125 mg/kg BW), with observation times of 30, 60, 90, 120, 150, and 180 minutes. The results showed that rats in group 5 with a dose of pucuk merah (125 mg/kgBW) had the best anti-inflammatory effect, with an anti-inflammatory potential of 97% compared to diclofenac sodium.
Hydrodynamic influences on acoustical and optical backscatter in a fringing reef environment

Observations of hydrodynamics along with optical and acoustical water characteristics in a tropical fringing reef environment reveal a distinct signature associated with flow characteristics and tidal conditions. Flow conditions are dominated by tidal forcing with an offshore component from the reef flat during ebb. Measurements span variable wave conditions enabling identification of wave effects on optical and acoustical water properties. High-frequency acoustic backscatter (6 MHz) is strongly correlated with tidal forcing increasing with offshore directed flow and modulated by wave height, indicating dominant hydrodynamic influence. Backscatter at 300 and 1200 kHz is predominantly diurnal suggesting a biological component. Optical backscatter is closely correlated with high-frequency acoustic backscatter across the range of study conditions. Acoustic backscatter frequency dependence is used along with changes in optical properties to interpret particle-size variations. Changes across wave heights suggest shifts in particle-size distributions with increases in relative concentrations of smaller particles for larger wave conditions. Establishing a connection between the physical processes of a fringing tropical reef and the resulting acoustical and optical signals allows for interpretation and forecasting of the remote sensing response of these phenomena over larger scales.
Stepwise clockwise rotation of the Cenozoic stress field in the Western Carpathians as revealed by kinematic analysis of minor faults in the Manín Unit (western Slovakia)

This study aims at quantitative kinematic analysis of fault-slip data and palaeostress reconstruction of polyphase brittle structures developed in the Manin Unit cropping out in the Middle Vah River Valley of western Slovakia. The Manin Unit neighbours the Pieniny Klippen Belt that follows the boundary between the Paleogene accretionary wedge of the Outer Carpathians and the Cretaceous nappe system of the Central Western Carpathians. After the nappe emplacement during mid-Cretaceous times, the Manin Unit was incorporated into the Pieniny Klippen Belt and attained its complex tectonic style. Based on kinematic analysis of meso-scale faults with slickensides, six (D 1 –D 6 ) brittle deformation stages have been discerned. The relative succession of individual palaeostress states was derived from field structural relationships; their stratigraphic age was estimated primarily by comparison with other published data. Palaeostress analysis in the Manin Unit revealed the existence of six different palaeostress fields acting from the Middle Eocene to the Quaternary. The first three generations of meso-scale brittle structures were formed under a transpressional tectonic regime during the pre-Late Eocene–Early Miocene D 1 –D 3 deformation. Generally, the maximum horizontal stress axis rotated clockwise from a W–E to an approximately N–S direction. Thereafter, a transtensional tectonic regime was characterized by a WNW–ESE to NNW–SSE oriented minimum horizontal stress axis during Middle and Late Miocene D 4 –D 5 deformation. A general extensional tectonic regime influenced the structural evolution of the area in the Pliocene to Quaternary, when a gradual reorientation of the palaeostress field resulted in the development of variable, often reactivated, fault structures.
Medical Doctors Approaches and Understanding of Health Literacy: A Systematic Literature Review

A physician's role is critical in fostering patient health literacy (HL) and influencing various aspects, including patient-physician communication and treatment effectiveness. The purpose of this systematic literature review is to analyze physicians' perspectives, comprehension, and management of HL. The focus of this review is on physicians' views, opinions, experiences, and strategies related to HL. We conducted comprehensive searches across seven databases, including PubMed, Scopus, ProQuest, Science Direct, Web of Science, The Cochrane Library, and Google Scholar. Original research articles published between January 1, 2009, and July 31, 2020, were considered for inclusion. This literature review incorporates qualitative studies and mixed-methods studies, with a focus on extracting qualitative data. Among the 22 articles included in our review, we employed the method of inductive thematic analysis for data analysis. A detailed description of the review methodology can be found in a previously published protocol available through PROSPERO (CRD42020212599). The themes that emerged from the thematic analysis include: (a) physicians' perception and management of HL; and (b) barriers. The results of the systematic review reveal that healthcare professionals exhibit varying perceptions of patients' HL levels and ascribe different meanings to it. However, none of them employ a specific measuring tool. While there appears to be no uniform approach to managing patients with low HL, some prioritize certain communication strategies, such as repetition, simplified language, and providing written instructions, among others. Most physicians cited multiple barriers that impede the development of patients' HL, including dysfunctions within the healthcare system, staff shortages, managing a large number of patients, limited time, work-related stress, cultural and socio-economic barriers, medical jargon, and language barriers. Considering the pivotal role of physicians in fostering patient HL, it is crucial to enhance medical education in addressing and managing HL, both within academic curricula and through continuing education seminars. Furthermore, there is a pressing need to improve healthcare professionals' working conditions, ensuring that each physician can allocate the necessary time to each patient based on their individual needs, without being hindered by stress-inducing work environments.
Time-Varying Tracking Control of a Unicycle Mobile Robot: A Composite Lyapunov Function Approach

This work proposes the design of an adaptive robust controller for the perturbed kinematic model of the unicycle mobile robot. The controller is based on the concept of composite Lyapunov functions. The methodology ensures the stability of the tracking error despite the presence of multiplicative disturbances in the control channel. The synthesis of the proposed controller requires the solution of a set of off-line Linear Matrix Inequalities and the solution of an optimization process regarding the com-posite Lyapunov approach. Simulation results show the feasibility of the proposed strategy against classical controllers.
SLA formulation for squeezed protection in elastic optical networks considering the modulation format

In spectrum-sliced elastic optical path networks (SLICE), the lightpath bandwidth is variable, and the virtual topology overlay on a physical topology shall be designed to optimize the spectrum utilization. Under static traffic, SLICE networks are typically designed through a mixed integer linear programming (MILP) with the aim of minimizing the spectrum utilization. In this paper, a new MILP formulation for protection in SLICE networks is proposed, which uses the concept of bandwidth squeezing and grooming to guarantee a minimum agreed bandwidth for each source-destination pair in the surviving bandwidth. The route for each demand on the physical topology is determined by balance equations together with physical layer constraints in the formulation, so that no pre-calculated routes are required and the modulation format of each established lightpath may be chosen with enough quality of transmission and to save network spectrum. Therefore, the proposed formulation jointly solves the virtual topology design and physical topology design problems. The first results evaluate the effectiveness of the MILP formulation for two small networks when connections are under different service-level agreement (SLA) requirements and are provisioned by an appropriate protection scheme and different modulation formats. Due to the NP-hard nature of the proposed MILP formulation, a heuristic algorithm for moderately large networks is also proposed. Case studies are carried out to analyze the basic properties of the formulation and the performance of the proposed heuristic. With the proposed formulation, it is possible to identify the configurations that ensure minimum spectrum occupation with different kinds of protection for each lightpath. Different kinds of modulation formats are considered and contrasted to the benchmark case of a single modulation format and using the same kind of protection for all lightpaths.
Documentation of a Linked-Population Viability Model to Evaluate Recovery Options for Snake River Fall Chinook Salmon

We developed an age- and life-history based population viability analysis model for linked populations of fall Chinook salmon (LPVA). LPVA was designed to quantify the costs and benefits of re-establishing access to an upstream spawning area using managed reconnection options such as hatchery stocking and translocation. The model incorporates stochasticity in the age at which salmon return to spawn, sex ratio, juvenile life history, and survival rates. Response variables include the proportion of replicate populations that persisted for 80 y (roughly 20 generations), the linked population’s growth rate, λ, time to extinction and summaries of population sizes including average female spawner abundance, final female spawner abundance, and total female abundance. This report attempts to provide a complete model description, including simulation of management options and options for simulating forward with a joint distribution of parameters based on their likelihoods with respect to historical data. Intermediate results illustrating the Bayesian approach to identifying poorly-known parameters are reported here. LPVA simulates reconnection of linked populations by representing management processes such as trapping of adults migrating upstream at two dams and juveniles migrating downstream, and hatchery operations for one or two hatcheries. The purpose of the model is to support efforts to recover the threatened Snake River fall Chinook salmon ESU by evaluating population viability using existing spawning areas with and without a hatchery and to assess the potential costs and benefits of programs to re-establish an upstream spawning area.
