Observation of Compressional Alfven Modes during Neutral Beam Heating on the National Spherical Torus Experiment

Neutral-beam-driven compressional Alfven eigenmodes (CAE) at frequencies below the ion cyclotron frequency have been observed and identified for the first time in the National Spherical Torus Experiment (NSTX). The modes are observed as a broad spectrum of nearly equally spaced peaks in the frequency range from approximately 0.2 to approximately 1.2 omega(subscript ''ci''). The frequency has a scaling with toroidal field and plasma density consistent with Alfven waves. The modes have been observed with high bandwidth magnetic pick-up coils and with a reflectometer.
An Analysis of Factors Affecting the Successful Implementation of Educational Policies in Developing Countries

This research sought to evaluate the variables influencing the successful implementation of educational policies in underdeveloped countries, with a particular emphasis on Ghana. In this study, a quantitative research approach was taken, and data were gathered through the administration of a survey to a sample size of one hundred fifty policymakers and instructors in Ghana. In order to evaluate the data, both descriptive and inferential statistics were utilized. According to the conclusions, there is a favorable correlation between successful implementation and the governmental, economic, social, and societal variables as well as technological factors. The strongest associations were identified for technological and cultural variables, which suggests that expenditures in technological advancement and cultural awareness can have a beneficial effect on the implementation of educational policies. According to the findings of the multiple regression analysis, all of the variables had a substantial favorable impact on the successful implementation of the plan, with the technological elements demonstrating the strongest effect. According to the findings of the research, in order for educational policies to be successfully implemented in developing countries, a holistic strategy that takes into consideration all of the important variables is required. By considering these variables, policymakers in developing countries will be able to improve the efficacy of educational programs and encourage egalitarian access to education. This research provides important insights for policymakers and stakeholders interested in the administration of educational strategies in underdeveloped countries.
Nutritional Status and Dietary Practices of Elderly People Living In Community Dwelling and Old Age Home In Tanahun District, Nepal

Background: The main objective of the study was to access the nutritional status and dietary practice of elderly population living in community dwelling and old age home of Tanahun district, Nepal. Methods: Community-based cross-sectional comparative study was conducted in Tanahun district. The Mini-Nutritional Assessment tool was used to investigate the nutritional status and dietary practices. It was identified by using weekly food consumption and 24 hours dietary recall questionnaires. Data were entered in Epi-Data (version 3.1) and analyzed by SPSS (version 20). Result: Among 202 respondents (101 each from community dwellings and old age home), 44.5% were at risk of malnutrition, 5.9% were malnourished and 49.5% had normal nutrition status in community dwelling. Similarly, 55.4% were at risk of malnutrition, 17.8% were malnourished and 26.7% had normal nutrition status in old age home. In both settings, consumption of protein is low and consumption of vegetables is high. There was a significant association between socio-demographic variables such as living settings, age and education with nutritional status of elderly population. Age (AOR =0.0.186, p= 0.01) and education (AOR = 5.419, p= 0.006) shows significant association with nutritional status. Conclusion: Overall half of them were at risk of malnutrition in both settings due to poor dietary practices, loss of appetite, weight loss, morbidity, neuropsychological problems among senior people. Cardinal focus should be given to improve the consumption of protein in dietary practices. Further longitudinal research studies should be conducted to determine factor associated with malnutrition to prevent malnutrition at regional and national level.
A robust optimization methodology for preliminary aircraft design

This article focuses on a robust optimization of an aircraft preliminary design under operational constraints. According to engineers' know-how, the aircraft preliminary design problem can be modelled as an uncertain optimization problem whose objective (the cost or the fuel consumption) is almost affine, and whose constraints are convex. It is shown that this uncertain optimization problem can be approximated in a conservative manner by an uncertain linear optimization program, which enables the use of the techniques of robust linear programming of Ben-Tal, El Ghaoui, and Nemirovski [Robust Optimization, Princeton University Press, 2009]. This methodology is then applied to two real cases of aircraft design and numerical results are presented.
GLOBAL EXISTENCE AND GRADIENT BLOWUP OF SOLUTIONS FOR A SEMILINEAR PARABOLIC EQUATION WITH EXPONENTIAL SOURCE

Throughout this paper, we consider the equation \[u_t - \Delta u = e^{|\nabla u|}\] with homogeneous Dirichlet boundary condition. One of our main goals is to show that the existence of global classical solution can derive the existence of classical stationary solution, and the global solution must converge to the stationary solution in $C(\overline{\Omega})$. On the contrary, the existence of the stationary solution also implies the global existence of the classical solution at least in the radial case. The other one is to show that finite time gradient blowup will occur for large initial data or domains with small measure.
Anticonvulsant Profile of Selected Medium-Chain Fatty Acids (MCFAs) Co-Administered with Metformin in Mice in Acute and Chronic Treatment

In contrast to the other components of the medium-chain triglycerides ketogenic diet (MCT KD), i.e., caprylic acid (CA8), a comprehensive evaluation of caproic (CA6) and lauric acids’ (CA12) properties in standard chemical and electrical seizure tests in mice has not yet been performed. We investigated their effects in maximal electroshock seizure threshold (MEST), 6 Hz seizure threshold and intravenous (i.v.) pentylenetetrazole (PTZ) seizure tests. Since ketone body production can be regulated by the activation of 5′AMP-activated protein kinase (AMPK), we hypothesized that metformin (an AMPK activator) enhance ketogenesis and would act synergistically with the fatty acids to inhibit convulsions. We assessed the effects of acute and chronic co-treatment with metformin and CA6/CA8 on seizures. CA6 and CA12 (p.o.) increased seizure threshold in the 6 Hz seizure test. CA6 at the highest tested dose (30 mmol/kg) developed toxicity in several mice, impaired motor performance and induced ketoacidosis. Acute and chronic co-treatment with metformin and CA6/CA8 did not affect seizure thresholds. Moreover, we observed the pro-convulsive effect of the acute co-administration of CA8 (5 mmol/kg) and metformin (100 mg/kg). Since this co-treatment was pro-convulsive, the safety profile and risk/benefit ratio of MCT KD and metformin concomitant therapy in epileptic patients should be further evaluated.
Measuring Interprofessional Collaboration’s Impact on Healthcare Services Using the Quadruple Aim Framework: A Protocol Paper

Despite decades of research on the impact of interprofessional collaboration (IPC), we still lack definitive proof that team-based care can lead to a tangible effect on healthcare outcomes. Without return on investment (ROI) evidence, healthcare leaders cannot justifiably throw their weight behind IPC, and the institutional push for healthcare manpower reforms crucial for facilitating IPC will remain variable and fragmentary. The lack of proof for the ROI of IPC is likely due to a lack of a unifying conceptual framework and the over-reliance on the single-method study design. To address the gaps, this paper describes a protocol which uses as a framework the Quadruple Aim which examines the ROI of IPC using four dimensions: patient outcomes, patient experience, provider well-being, and cost of care. A multimethod approach is proposed whereby patient outcomes are measured using quantitative methods, and patient experience and provider well-being are assessed using qualitative methods. Healthcare costs will be calculated using the time-driven activity-based costing methodology. The study is set in a Singapore-based national and regional center that takes care of patients with neurological issues.
Ship Detection From Raw SAR Echo Data

In the context of ship monitoring in the ocean, targets are usually sparsely distributed. Thus, synthetic aperture radar (SAR) imaging of the whole scene is usually quite redundant and costly. However, raw SAR echo data were considered to be useless before focusing. Few studies have attempted to detect ships from raw SAR echo data. It seems to be an impossible task since the resolution of raw SAR echo data is too low. This article proposes a ship detection method for raw SAR echo data in view of a nonimaging target sensing paradigm. The core idea is that we can sense the existence of ships from raw SAR echo data without imaging. The underlying rationale is that the radar always speaks the same sentence, i.e., usually an exactly identical linear frequency modulated (LFM) signal, while target and clutter answer differently. The difference spread into each part of the whole echo sequence rather than only the focused energy after match filtering. Thus, the ships can be found by pattern analysis on one-dimension sequence data rather than two-dimension images. The experimental results based on simulation and typical real data validate our assumption. This study shows that SAR imaging is an unnecessary intermediate process and opens up new significant possibilities for ship detection in the vast ocean.
Hearing health educational interventions for school students

ABSTRACT Purpose: to implement and assess hearing health interventions for school students, using Dangerous Decibels® Program activities in partnership with the Young Doctor Project, approaching noise-induced hearing loss prevention. Methods: the study encompassed 41 students, aged 12 to 14 years, from two schools in inland São Paulo and a social institution for public school students. Activities were based on the Young Doctor Project and the Dangerous Decibels® Brazil Program. The students answered a questionnaire administered in three situations: before the intervention (pre), right after the intervention (post), and 4 months after the intervention. The ANOVA, Friedman (p < 0.001), and Tukey´s (p < 0.05) statistical tests were used. Results: the 41 students who participated in the program were protagonists of knowledge, spreading the content they learned to another 954 students in the three schools through cultural workshops. The analysis of program effectiveness revealed improved results right after the intervention and 4 months afterward. Conclusion: combining these two programs encouraged the protagonism of young people to increase their involvement with the community. Moreover, the students changed their attitude toward potentially dangerous sounds.
AMeta-Analysis ofHeavyweight andSelf-Esteem

This study isameta-analysis oftherelation ofheavyweight andself-esteem. Weexaminedthis relation instudies thatfocused onparticipants' actual bodyweight (assessed byphysical measures or self-reports ofweight and height)and studies thatfocused on self-perceived degree ofheavyweight orbodydissatisfaction. Theoverall mean effect size was moderate (r = -.18, d = -.36),with lower self-esteemassociated with heavier weight. Thecorrelation between self-esteem andweight was higher forstudies of self-perceived weight thanforstudies ofactual weight. Consistent withpredictions about cultural andgroupdifferences, effect sizes were smallerfor lowsocioeconomic status (SES) samples, ethnic minority samples, andnonclinical samples thanforhigh SES,nonminority, andclinical samples, respectively. Inaddition, effect sizes were largerfor women than formen andfor highschool andcollege students than forchildren. Discussion centered on cultural, group,andindividual differences that may influence theconsequenceson self-esteem ofviolating standards forappropriate body weight.
Paradoxical decompositions and the Axiom of Choice

The Banach-Tarski Paradox is probably the most counter-intuitive theorem in any field of mathematics. It states, in layman's terms, that a solid ball in R[real numbers]? can be split into finitely non-overlapping pieces, which can then be put back together in a different way only using rigid motions to produce two identical copies of the original ball. A stronger version of this paradox is often stated as "a pea can be chopped up and reassembled into the sun." This is possible to prove because of Banach and Tarski's use of the Axiom of Choice. Because of the increase in measure, these paradoxical decompositions must involve nonmeasurable sets. Measurable sets and sets with the property of Baire have a lot of similar characteristics, so it is natural to ask if the Banach-Tarski Paradox is possible using pieces that have the property of Baire. Surprisingly, as we will see, this is also possible.
Kernel-Based State-Space Kriging for Predictive Control

In this paper, we extend the state-space kriging (SSK) modeling technique presented in a previous work by the authors in order to consider non-autonomous systems. SSK is a data-driven method that computes predictions as linear combinations of past outputs. To model the nonlinear dynamics of the system, we propose the kernel-based state-space kriging (K-SSK), a new version of the SSK where kernel functions are used instead of resorting to considerations about the locality of the data. Also, a Kalman filter can be used to improve the predictions at each time step in the case of noisy measurements. A constrained tracking nonlinear model predictive control (NMPC) scheme using the black-box input-output model obtained by means of the K-SSK prediction method is proposed. Finally, a simulation example and a real experiment are provided in order to assess the performance of the proposed controller.
Inclusion of Stored Wheat in the Feed of Broilers Influences Intake, Growth Performance, Nutrient Digestibility, and Digesta Viscosity from 1-21 Days of Age

The objective of the current study was to examine the effect of replacing maize with new or stored wheat on the nutrient intake, digestibility, digesta viscosity, and growth performance of growing broilers from 1-21 days of age. For this purpose, 560 one-day-old male broiler chicks were randomly divided into seven experimental treatments, each with 8 replicates of 10 birds. The control diet was a corn soybean-based diet, while six other experimental treatments replaced the corn of the control diet with either 50% or 100% of new, 1.5 year, and 2.5-year-old wheat. The results showed that the replacement of corn with new wheat at 50% and 100% in the diet of broilers significantly reduced feed intake and body weight gain, and increased FCR ( p <0.05) at week 3. Similarly, in the overall period of the starter phase (1-21 days), replacement of corn with new wheat at 50% and 100% in the diet of broilers significantly reduced feed intake, nutrient digestibility, and body weight gain, and increased digesta viscosity and FCR ( p <0.05). Based on the findings of the current study, it is concluded that stored wheat successfully replaces corn and new wheat in the diet of broilers. Furthermore, stored wheat has a positive impact on feed intake, performance parameter, digesta viscosity, and nutrient digestibility as compared to new wheat.
Enhancing Safety using AR Headsets with Motion Prediction Visualization

Pedestrian collisions are a serious safety issue when considering hazards to elderly persons and to distracted people due to AR gaming. The inability to anticipate an oncoming danger could put these pedestrians at a safety risk endangering their lives. However if we use an AR device to visualise future motion, then this could firstly help elderly wearing them to forsee any oncoming danger and secondly alert a distracted AR gamer if this information is included in the game. The RGBD sensors of an AR device continuously scans the environment to place virtual content. Our prototype idea focuses on applying motion detection and prediction algorithms to this scan data, and communicating it as information to the users. Then other traffic participants, who might potentially get in conflict with an AR headset user can be predicted in advance and informed. This can not only promote the use of AR headsets as a safety aid especially for elderly and disabled but also increase safety in outdoor spaces when using AR. In this paper we share our first results for our prototype based on the above idea where future pedestrian motions are detected and visualised with Unity on the Hololens 2.
“Desde casa, desde berço, desde sempre”: violência e mulheres em situação de rua

Resumo: Mulheres em situação de rua sofrem violações e vulnerabilizações específicas e gendradas. Este estudo tem como objetivo examinar as diferentes manifestações e incidências da violência que as atinge. Foram realizadas nove entrevistas aprofundadas e pesquisa de campo de cunho etnográfico. Violências físicas e sexuais revelaram-se os principais deflagradores para a ida para as ruas, mas não sua causalidade, pois incidiram em vidas já devastadas por violências estruturais e interseccionais. O cotidiano nas ruas mostrou-se corroído por violências explícitas e veladas e pela submissão à violência como modo de sobrevivência. Destaca-se que gênero, raça e pobreza são acionados como autorização para a violência sobre os corpos e subjetividades dessas mulheres.
A Comparison of the Toxicities in Patients With Locally Advanced Head and Neck Cancers Treated With Concomitant Boost Radiotherapy Versus Conventional Chemoradiation

Purpose: To compare the objective and patient-reported toxicities of concomitant boost radiotherapy (CBRT) and concurrent chemoradiation (CRT) in patients with locally advanced head and neck cancers. Methods and material: In this prospective study, 46 patients with histologically proven stage III-IVA head and neck cancer were randomly assigned to receive either concurrent chemoradiation to a dose of 66 Gy in 33 fractions over 6.5 weeks with concurrent cisplatin (40 mg/m2 IV weekly; control arm) or accelerated radiotherapy with concomitant boost radiotherapy (study arm) to a dose of 67.5 Gy in 40 fractions in five weeks. Acute toxicity was evaluated using RTOG toxicity criteria. The assessment was done weekly after initiation of treatment, at the first follow-up (six weeks), and at three months. The four main patient-reported symptoms of pain, hoarseness of voice, dryness of mouth, and loss of taste were also compared between the two groups to assess patient quality of life during treatment. Results: The mean treatment duration was 37 days in the CBRT arm and 49 days in the CRT arm. Treatment-related interruptions were less in the study group,17.3% in the study, and 27.2% in the control with insignificant P-value. Grade III laryngeal toxicity was significantly higher in the study group (P=0.029). Other acute grade I-III toxicities (pharyngeal, skin, mucositis, and salivary) were comparable in both CRT and CBRT arms. Grade IV toxicities were seen only in the CBRT arm but were resolved at the first follow-up. Haematological toxicities and renal toxicities were significantly higher in the CRT arm, with significant P-values of 0.0004 and 0.018, respectively. Conclusion: In patients with locally advanced head and neck cancer, concomitant boost radiotherapy is well tolerated with acceptable local toxicity and minimal systemic toxicity as compared to conventional chemoradiation. It is a feasible option for patients with locally advanced head and neck cancer not fit for concurrent chemoradiation.
A Review on Elbow Biomechanics and Medical Applications in the field of Biomedical Engineering

The study of elbow biomechanics and anatomy can be simplified into observing how the humerus articulates with the ulna and the radius to create a composite synovial hinge joint made up of three sliding joints movements like flexion, extension, pronation, and supination. Through the humeroulnar, humeroradial, and radioulnar contact points, there exists cartilage, and various structures work together to stabilize and distribute the load on the joint. Knowledge of elbow biomechanics in conjunction with material selection allows biomedical engineers to understand better how to design prostheses that are biocompatible and ergonomic for the user. Total elbow arthroplasty is one example of an application of this topic in biomedical engineering.
Simulation numérique des écoulements de suspension à l'aide d'une méthode de pénalisation des équations de Navier-Stokes

A finite-size particle simulation for particulate flow model is presented. A one fluid model is used in which the solid character of the particles is treated by a high viscosity. The simulations are carried out on a staggered Cartesian grid. Particles are tracked in a Lagrangian manner. The particularity of this fictitious domain approach is that the effect of particles on the fluid is implicitly taken into account in the Navier-Stokes equations. The momentum equation solving ensures at the same time the solid and incompressible constraints. Mots clefs : turbulence, particle flow, finite-size, VOF, fictitious domain
One Hundred Inches in One Hundred Hours: Evolution of a Wasatch Mountain Winter Storm Cycle

Abstract Synoptic, orographic, and lake-effect precipitation processes during a major winter storm cycle over the Wasatch Mountains of northern Utah are examined using radar imagery, high-density surface data, and precipitation observations from Alta Ski Area [2600–3200 m above mean sea level (MSL)] and nearby Salt Lake City International Airport (1288 m MSL). The storm cycle, which occurred from 22 to 27 November 2001, included two distinct storm systems that produced 108 in. (274 cm) of snow at Alta Ski Area, including 100 in. (254 cm) during a 100-h period. Each storm system featured an intrusion of low equivalent potential temperature (θe) air aloft, well in advance of a surface-based cold front. Prefrontal precipitation became increasingly convective as low-θe air aloft moved over northern Utah, while cold frontal passage was accompanied by a convective line and a stratiform precipitation region. Postfrontal destabilization led to orographic and lake-effect snowshowers that produced two-thirds of the.
