Wire-antenna designs using genetic algorithms

There is a large class of electromagnetic radiators designated as wire antennas. As a rule, an inductive process is used to design these antennas. Either an integral equation is formulated or a simulator is used that gives the current distributions on the wires of the antenna, from which the electromagnetic properties of the antenna can then be determined. Once the antenna properties are known, the parameters are optimized, using guides such as intuition, experience, simplified equations, or empirical studies. However, using an electromagnetics simulator in conjunction with a genetic algorithm (GA), it is possible to design an antenna using a completely deductive approach: the desired electromagnetic properties of the antenna are specified, and the wire configuration that most closely produces these results is then synthesized by the algorithm. In this paper, we describe four antennas designed using GAs. The first is a monopole, loaded with a modified folded dipole that was designed to radiate uniform power over the hemisphere at a frequency of 1.6 GHz. The second antenna consists of seven wires, the locations and lengths of which are determined by the GA alone, that radiates waves with right-hand-circular polarization at elevation angles above 10/spl deg/, also at 1.6 GHz. The last two antennas are modified Yagis. One is designed for a broad frequency band and very low sidelobes at a center frequency of 235 MHz. The other is designed for high gain at a single frequency of 432 MHz. We have built and tested these antennas.
Upper Limb Movement Measurement Systems for Cerebral Palsy: A Systematic Literature Review

Quantifying the quality of upper limb movements is fundamental to the therapeutic process of patients with cerebral palsy (CP). Several clinical methods are currently available to assess the upper limb range of motion (ROM) in children with CP. This paper focuses on identifying and describing available techniques for the quantitative assessment of the upper limb active range of motion (AROM) and kinematics in children with CP. Following the screening and exclusion of articles that did not meet the selection criteria, we analyzed 14 studies involving objective upper extremity assessments of the AROM and kinematics using optoelectronic devices, wearable sensors, and low-cost Kinect sensors in children with CP aged 4–18 years. An increase in the motor function of the upper extremity and an improvement in most of the daily tasks reviewed were reported. In the population of this study, the potential of wearable sensors and the Kinect sensor natural user interface as complementary devices for the quantitative evaluation of the upper extremity was evident. The Kinect sensor is a clinical assessment tool with a unique markerless motion capture system. Few authors had described the kinematic models and algorithms used to estimate their kinematic analysis in detail. However, the kinematic models in these studies varied from 4 to 10 segments. In addition, few authors had followed the joint assessment recommendations proposed by the International Society of Biomechanics (ISB). This review showed that three-dimensional analysis systems were used primarily for monitoring and evaluating spatiotemporal variables and kinematic parameters of upper limb movements. The results indicated that optoelectronic devices were the most commonly used systems. The joint assessment recommendations proposed by the ISB should be used because they are approved standards for human kinematic assessments. This review was registered in the PROSPERO database (CRD42021257211).
Does diet breadth affect the complexity of the phytophagous insect microbiota? The case study of Chrysomelidae

Summary Chrysomelidae is a family of phytophagous insects with a highly variable degree of trophic specialization. The aim of this study is to test whether species feeding on different plants (generalists) harbour more complex microbiotas than those feeding on a few or a single plant species (specialists). The microbiota of representative leaf beetle species was characterized with a metabarcoding approach targeting V1–V2 and V4 regions of the bacterial 16S rRNA. Almost all the analysed species harbour at least one reproductive manipulator bacteria (e.g., Wolbachia, Rickettsia). Two putative primary symbionts, previously isolated only from a single species (Bromius obscurus), have been detected in two species of the same subfamily, suggesting a widespread symbiosis in Eumolpinae. Surprisingly, the well‐known aphid symbiont Buchnera is well represented in the microbiota of Orsodacne humeralis. Moreover, in this study, using Hill numbers to dissect the components of the microbiota diversity (abundant and rare bacteria), it has been demonstrated that generalist insect species harbour a more diversified microbiota than specialists. The higher microbiota diversity associated with a wider host‐plant spectrum could be seen as an adaptive trait, conferring new metabolic potential useful to expand the diet breath, or as a result of environmental stochastic acquisition conveyed by diet.
HARTH: A Human Activity Recognition Dataset for Machine Learning

Existing accelerometer-based human activity recognition (HAR) benchmark datasets that were recorded during free living suffer from non-fixed sensor placement, the usage of only one sensor, and unreliable annotations. We make two contributions in this work. First, we present the publicly available Human Activity Recognition Trondheim dataset (HARTH). Twenty-two participants were recorded for 90 to 120 min during their regular working hours using two three-axial accelerometers, attached to the thigh and lower back, and a chest-mounted camera. Experts annotated the data independently using the camera’s video signal and achieved high inter-rater agreement (Fleiss’ Kappa =0.96). They labeled twelve activities. The second contribution of this paper is the training of seven different baseline machine learning models for HAR on our dataset. We used a support vector machine, k-nearest neighbor, random forest, extreme gradient boost, convolutional neural network, bidirectional long short-term memory, and convolutional neural network with multi-resolution blocks. The support vector machine achieved the best results with an F1-score of 0.81 (standard deviation: ±0.18), recall of 0.85±0.13, and precision of 0.79±0.22 in a leave-one-subject-out cross-validation. Our highly professional recordings and annotations provide a promising benchmark dataset for researchers to develop innovative machine learning approaches for precise HAR in free living.
The Effect of Mindfulness and Religious Coping on Elderly Mental Health

The elderly population continues to increase not only in the world, but also in Indonesia. One of the cities that contribute to increasing the number of elderly people in Indonesia is Depok, West Java. Elderly is a stage that has experienced many changes and faced various challenges in life. The elderly tend to experience a decline in various aspects. They experience changes in physical, psychological, and social aspects. The changes that occur and all the challenges that must be faced can have an impact on the physical, mental and functioning of life. This study aims to examine whether mindfulness and religious coping have an effect on the mental health of the elderly in Depok city. The sample used were 282 elderly people who were taken using a non-probability sampling technique, namely purposive sampling. The instruments used in this study are adaptations and modifications of the Mental Health Continuum-Long Form (MHC-LF), Five Facet Mindfulness Questionnaire (FFMQ) and Brief RCOPE instruments. The results showed that at 36.5%, there was a significant effect of mindfulness and religious coping together on the mental health of the elderly. In detail, the results of the minor hypothesis prove that there is a significant effect of three dimensions of mindfulness (observe, describe, and act with awareness) and one dimension of religious coping (positive religious coping) on the mental health of the elderly.
Retinal Diseases Regulated by Hypoxia—Basic and Clinical Perspectives: A Comprehensive Review

In recent years, the number of patients with age-related macular degeneration (AMD) is increasing worldwide along with increased life expectancy. Currently, the standard treatment for wet-AMD is intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs. The upstream of VEGF is hypoxia-inducible factor (HIF), a master regulator of hypoxia-responsive genes responsive to acute and chronic hypoxia. HIF activation induces various pathological pro-angiogenic gene expressions including VEGF under retinal hypoxia, ultimately leading to the development of ocular ischemic neovascular diseases. In this regard, HIF is considered as a promising therapeutic target in ocular ischemic diseases. In clinical ophthalmology, abnormal hypofluorescent areas have been detected in the late-phase of indocyanine green angiography, which are thought to be lipid deposits at the level of Bruch’s membrane to choriocapillaris in vitreoretinal diseases. These deposits may interfere with the oxygen and nutrients that should be supplied to the retinal pigment epithelium, and that HIF/VEGF is highly suspected to be expressed in the hypoxic retinal pigment epithelium, leading to neovascularization. In this review, we comprehensively summarize pathophysiology of AMD-related ocular diseases with the HIF/VEGF pathway from basic and clinic researches with recent findings.
Public-Private Partnership approach towards enhancing water accessibility in Busia Municipality, Kenya

Access to safe drinking water remains a challenge for most developing countries including Kenya, which is already classified as water-scarce. To enhance water supply to consumers, the Government of Kenya enacted the Water Act 2002 that opened the door for private sector to partner with the government to revitalize water service delivery. As a result, the government has partnered with the private sector and civil society organizations to enhance access to safe drinking water and sanitation services with a special focus on the materially-dispossessed households. However, the partnership is faced with challenges including inadequate resources and poor working relationship between the public and private sector. This paper assesses the impact of the partnership approach in scaling up water service provision in order to enhance its access by poor households. Household survey and key informants interviews were the main data collection methods and the collected data was analysed using descriptive statistics. The study found out that Public-Private Partnership (PPP) approach has enhanced water accessibility in Busia Municipality since the majority of households (84.4%) can access water within a distance less than one kilometre, however, the residents' complaint of high water bills attributed to the private sector involvement.
The Role of Serology Testing in the Context of Immunization Policies for COVID-19 in Latin American Countries

This review aims to explore the role and value of serology testing in the context of COVID-19 immunization policies in Latin American countries and the barriers and challenges to the adequate use and uptake of this tool. It builds on a review of the academic literature, evidence, and existing policies, and includes a multistage process of discussion and feedback by a group of five experts. Regional and country-level evidence and resources from five focus countries—Argentina, Brazil, Chile, Colombia, and Mexico—were collected and analyzed. This review contains an overview of (1) the impact of the SARS-CoV-2 pandemic, the variants of concern and current testing strategies, (2) the introduction of COVID-19 vaccination, (3) the potential use of serology testing to support immunization initiatives, (4) the current frameworks for the use of serology testing in the region, and (5) the barriers and challenges to implementing serology testing in the context of COVID-19 immunization policies, including a discussion on the potential actions required to address these barriers and facilitate the uptake of this strategy in the region. Stakeholders can use elements of this document to guide timely decision-making, raise awareness, and inspire further studies.
Dynamic Response of a Simply Supported Plate Due to Excitation at Different Points

The rectangular plate vibration has been of immense interests to the researchers for a long time. In this literature, an investigation is performed to measure the dynamic response at the different points on a rectangular plate due to excitation at different points. The possibility of occurring different modes of vibration at the different points on the plate according to the position of excitation is demonstrated and explained from the modal shape of the plate obtained from the modal analysis. A conventional approach is performed to obtain the modes and the modes are compared with the FEM results. An analytical equation is used to obtain the dynamic deflection of harmonic excitation for free vibration to observe the occurring of different modes and also used to validate the results obtained from the finite element method. Then a constant damping condition is simulated to understand properly the variation of amplitude at different points of plate for different excitation conditions. Keywords—simply supported plate, dynamic response, finite element method (FEM), harmonic excitation
Pathways toward Inclusive Income Growth: A Comparative Decomposition of National Growth Profiles

Despite rising interest in income inequality, scholars remain divided over the mechanisms underlying inclusive income growth and how these mechanisms vary across countries. This study introduces the concept of national growth profiles, that is, the additive contribution of changes in taxes, transfers, composition, and other factors including market institutions to changes across a country’s income distribution. We present a decomposition framework to measure national growth profiles for eight high-income countries from the 1980s to 2010s. Our findings adjudicate competing sociological and economic perspectives on rising inequality. First, we find that policy-driven changes in taxes and transfers are the dominant drivers of inclusive growth at the tails of the income distributions. Second, rising educational attainment contributes most to income growth across the distribution, but consistently contributes to less-inclusive growth. When changes in education are considered, changes in assortative mating and single parenthood have little consequence for changes in inequality. Third, changes to other factors including market institutions increased inequality in countries such as the United States, but less so in France and Germany. Had the United States matched the changes to Dutch tax policy, Danish transfer policy, or other factors of most other countries, it could have achieved more inclusive income growth than observed.
Cultural and contextual considerations in designing programs to support the incorporation of early childhood development within ongoing national nutrition programmes: A focus on the Baby-Friendly Community Initiative (BFCI) in a rural African context

The Baby Friendly Community Initiative (BFCI) offers a unique platform for integration of counselling on early childhood development (ECD) with existing maternal and child health and nutrition messages. To understand how to efficiently deliver such a program, this study determined the feasibility of integrating counselling on child stimulation into the Kenyan BFCI activities. Qualitative interviews (N=97) among female (aged 15-49 years) and male users, stakeholders, and services providers in Koibatek sub-County (mainly inhabited by the Tugen people, a Nilotic group in sub-Saharan Africa) provided extensive information on understanding regarding ECD, caregiving beliefs, needs at different levels and barriers and facilitators. Contextual influences and existing health system infrastructure are important considerations when designing integrated interventions to improve nurturing care of children.
Associated Factors of Sarcopenia in Community-Dwelling Older Adults: A Systematic Review and Meta-Analysis

(1) Background: To review the associated factors of sarcopenia in community-dwelling older adults. (2) Methods: PubMed, Embase, Web of Science, and four Chinese electronic databases were searched for observational studies that reported the associated factors of sarcopenia from inception to August 2021. Two researchers independently selected the literature, evaluated their quality, and extracted relevant data. The pooled odds ratio (OR) and its 95% confidence interval (CI) were calculated for each associated factors of sarcopenia using random-effects/fixed-effects models. Publication bias was assessed using funnel plot and the Eggers test. We performed statistical analysis using Stata 15.0 software. (3) Results: A total of 68 studies comprising 98,502 cases were included. Sociodemographic associated factors of sarcopenia among community-dwelling older adults included age (OR = 1.12, 95% CI: 1.10–1.13), marital status (singled, divorced, or widowed) (OR = 1.57, 95% CI: 1.08–2.28), disability for activities of daily living (ADL) (OR = 1.49, 95% CI: 1.15–1.92), and underweight (OR = 3.78, 95% CI: 2.55–5.60). Behavioral associated factors included smoking (OR = 1.20, 95% CI: 1.10–1.21), physical inactivity (OR = 1.73, 95% CI: 1.48–2.01), malnutrition/malnutrition risk (OR = 2.99, 95% CI: 2.40–3.72), long (OR = 2.30, 95% CI: 1.37–3.86) and short (OR = 3.32, 95% CI: 1.86–5.93) sleeping time, and living alone (OR = 1.55, 95% CI: 1.00–2.40). Disease-related associated factors included diabetes (OR = 1.40, 95% CI: 1.18–1.66), cognitive impairment (OR = 1.62, 95% CI: 1.05–2.51), heart diseases (OR = 1.14, 95% CI: 1.00–1.30), respiratory diseases (OR = 1.22, 95% CI: 1.09–1.36), osteopenia/osteoporosis (OR = 2.73, 95% CI: 1.63–4.57), osteoarthritis (OR = 1.33, 95% CI: 1.23–1.44), depression (OR = 1.46, 95% CI: 1.17–1.83), falls (OR = 1.28, 95% CI: 1.14–1.44), anorexia (OR = 1.50, 95% CI: 1.14–1.96), and anemia (OR = 1.39, 95% CI: 1.06–1.82). However, it remained unknown whether gender (female: OR = 1.10, 95% CI: 0.80–1.51; male: OR = 1.50, 95% CI: 0.96–2.34), overweight/obesity (OR = 0.27, 95% CI: 0.17–0.44), drinking (OR = 0.92, 95% CI: 0.84–1.01), hypertension (OR = 0.98, 95% CI: 0.84–1.14), hyperlipidemia (OR = 1.14, 95% CI: 0.89–1.47), stroke (OR = 1.70, 95% CI: 0.69–4.17), cancer (OR = 0.88, 95% CI: 0.85–0.92), pain (OR = 1.08, 95% CI: 0.98–1.20), liver disease (OR = 0.88, 95% CI: 0.85–0.91), and kidney disease (OR = 2.52, 95% CI: 0.19–33.30) were associated with sarcopenia. (4) Conclusions: There are many sociodemographic, behavioral, and disease-related associated factors of sarcopenia in community-dwelling older adults. Our view provides evidence for the early identification of high-risk individuals and the development of relevant interventions to prevent sarcopenia in community-dwelling older adults.
The Free Decay of Coupled Heave and Pitch Motions of a Model Frigate

A ship motions program has been found to over predict damping especially at resonant frequencies, resulting in there being no significant peak in the transfer function of pitch at resonance. Presented here is a series of experiments that measured the decay time histories of a model frigate free to move in the vertical plane, in an attempt to identify where the problems might be occurring. This paper provides a comparison of the heave and pitch motion decay time histories together with the analytical decay time histories synthesised using the hydrodynamic coefficients predicted by the PAT suite, a suite of ship motion computer programs. The authors make judgements concerning the components in the heave pitch motion using the terms in the full two dimensional strip theory heave and pitch motion equations to explain the trends shown. The investigation has shown that the sectional damping coefficient appears to be over predicted. This results in a relatively poor prediction of heave decay curves at low speed and over estimates the damping in the pitch decay curves. The heaving motion of a ship is dominated at low frequencies by the stiffness terms. The amount of damping at these frequencies are negligible and any errors in the damping terms has little effect on the transfer functions. The actual values of heave damping at resonance appears to be correct, but because of the nature of the coupled system of equations the heave sectional damping has a magnified effect in the pitch equation. however, the small errors identified in the time history comparisons do not appear large enough to account for the differences seen in t he transfer functions. Therefore, it appears that the discrepancies seen in the heave pitch transfer functions could be die to the wave excitation being predicted incorrectly. The paper also illustrates the need to consider only small amplitude motions when carrying out experiments of a linear nature.
Perceptions and explanations of status in the United Arab Emirates: The role of ascribed and achieved characteristics

Ascribed and achieved characteristics influence individuals’ positions in a social hierarchy. I explore how status characteristics and status ideologies influence expectations about economic opportunities in the United Arab Emirates, a wealthy, highly diverse, and internationally stratified society where beliefs in meritocracy are nationally supported. In Studies 1 and 2, participants reported the extent to which they perceived various characteristics to influence an individual’s salary. Participants whose nationality placed them higher in the economic hierarchy expected achieved markers of status to play a larger role than ascribed markers in determining pay. Across groups, the more participants believed in meritocracy, the more they expected achieved markers to play a role. In Study 3, participants predicted the economic success of individuals who varied in ascribed and achieved characteristics. Across participant groups, both ascribed and achieved characteristics were expected to influence an individual’s economic success. Taken together, results suggested that both ascribed and achieved characteristics are expected to influence an individual’s position in the socioeconomic hierarchy, but only differences rooted in achieved characteristics are legitimized. Group differences and implications for system stability are discussed.
Personality Traits Across the Life Cycle: Disentangling Age, Period, and Cohort Effects

Economists increasingly recognise the importance of personality traits for socio-economic outcomes, but little is known about the stability of these traits over the life cycle. Existing empirical contributions typically focus on age patterns and disregard cohort and period influences. This paper contributes novel evidence for the separability of age, period, and cohort effects for a broad range of personality traits based on systematic specification tests for disentangling age, period and cohort influences. Our estimates document that for different cohorts, the evolution of personality traits across the life cycle follows a stable, though non-constant, age profile, while there are sizeable differences across time periods.
