A Single-Layer Dual-Band Array at Low Frequency Ratio with Concurrent Broad Fan Beam and Narrow Pencil Beam

A single-layer, dual-band, shared-aperture array with a broad fan beam in the lower band centered at 5 GHz and a narrow pencil beam in the adjacent upper band centered at 5.8 GHz is presented in this paper. First, the schematic diagram of a dual-band array with its beamwidth regulation capability is presented. Then, two key components, i.e., a novel dual-band patch antenna element and a compact filtering phase shifter (FPS) are developed. The antenna element has counterintuitive beam patterns with broad azimuthal half-power beamwidth (HPBW) of 183.3° in the lower band but much narrower azimuthal HPBW of 68.5° in the upper band, indicating its excellent ability in beamwidth regulation with a figure of merit (FoM) of 2.31. Meanwhile, the FPS serves as a band-stop filter in the lower band and a phase shifter in the upper band. Furthermore, a two-element series-fed subarray is designed by cascading two properly designed antenna elements through the FPS. Finally, a parallel-series-fed array consisting of four rows of the series-fed subarrays is implemented, and a prototype is fabricated and tested. The measured results, in good agreement with the simulated ones, have demonstrated that the array satisfactorily attains a broad fan beam with azimuthal HPBW of 156° and gain of 11.05 dBi at 5 GHz and a narrow pencil beam with azimuthal HPBW of 30° and gain of 16.23 dBi at 5.8 GHz under a shared aperture of 1. 37λ0×3. 53λ0×0. 05λ0, indicating an enhanced FoM up to 4.48. The FoM and gain could be further improved by simply expanding the array’s dimension based on the developed array topology.
Sandwich Integration Technique for the Pressure Sensor Detection of Occlusal Force In Vitro

Bite force measurement is an important parameter when checking the function and integrity of the masticatory system, whereas it is currently very difficult to measure bite force during functional movement. Hence, the purpose of this study is to explore the potential technique and device for the measurement and intervention of the continuous bite forces on functional and dynamic occlusal condition. A portable biosensor by sandwich technique was designed, and the validity, reliability, and sensitivity were determined by mechanical pressure loading tests; meanwhile, the pressure signal is acquired by, and transmitted to, voltage changes by the electrical measurements of the sensors. The result is that, when the mechanical stress detection device is thicker than 3.5 mm, it shows relatively ideal mechanical properties; however, when the thickness is less than 3.0 mm, there is a risk of cracking. Mechanical stress changing and voltage variation had a regularity and positive relationship in this study. The mechanical stress-measuring device made by medical and industrial cross has a good application prospect for the measurement of bite force during function.
Nursing Students’ Experiences on Clinical Competency Assessment in Ghana

Background: More countries are establishing licensing examination systems for nursing education, including clinical competency assessment. In Ghana, clinical competency assessment forms part of the nursing licensing examination and is perceived as the benchmark for nursing licensing examination in the sub-region. The nationalised assessment system is established with some ad hoc changes over the last decade which requires continual evaluation. It is essential to find out how students experience this assessment system. Purpose: This study aimed to explore nursing students’ experiences of the clinical competency assessment in Ghana. Methods: An exploratory descriptive qualitative design was used in this study. Eight focus group discussions (FGDs) were conducted with 68 final year students purposively selected from eight nursing education programs. The FGDs lasted between 90 to 120 minutes. Content analysis was used to analyze the data.Results: Although the pre-examination conference between students and examiners helped lessen students’ anxiety, limited resources, incongruence in teaching, practice and assessment, inherent biases due to the unstandardised assessment system, and a financial burden compromised the quality of the assessment.Conclusion:Clinical competency assessment is central to nursing licensing examinations; hence the ability of the system to discriminate competent and incompetent nurses otherwise cannot be overemphasised. Standardisation, training of the examiners and continuous evaluation of the assessment system are imperative for quality improvement in clinical competency assessment.
An Open-Label, Pilot Trial of HRG80™ Red Ginseng in Chronic Fatigue Syndrome, Fibromyalgia, and Post-Viral Fatigue

Chronic fatigue syndrome and fibromyalgia (CFS/FMS) affect 2.1% of the world’s population and ~10–25% of people who have had COVID-19. Previous clinical data suggested that a unique Panax ginseng (C.A. Meyer, family Araliaceae) root extract (HRG80™ Red Ginseng) often resulted in marked improvement. We aimed to study this hydroponic form of red ginseng root, containing high levels of rare ginsenosides, for improving energy, cognition, and stamina. This open-label prospective study included participants with severe CFS/FMS who took a daily supplement of HRG80 capsules (200–400 mg) or tablets (100–200 mg) for one month. A total of 188 subject patients completed the one-month treatment trial. Of these, 60.1% rated themselves as improved, with 13.3% rating themselves as being much better. In this group, the mean composite score improved from 11.9 to 18.8 (p < 0.001), with a 67% average increase in energy, 44% average increase in overall well-being, 48% average improvement in mental clarity, 58% average composite improvement in the previous three measurements (primary outcome measure), 46% average improvement in sleep, 33% average decrease in pain, and 72% average increase in stamina. Our study showed that HRG80 red ginseng root powder resulted in a marked improvement in people with CFS and fibromyalgia. This included the subgroup with post-viral CFS/FMS.
Individual Identification with Short Tandem Repeat Analysis and Collection of Secondary Information Using Microbiome Analysis

Forensic investigation is important to analyze evidence and facilitate the search for key individuals, such as suspects and victims in a criminal case. The forensic use of genomic DNA has increased with the development of DNA sequencing technology, thereby enabling additional analysis during criminal investigations when additional legal evidence is required. In this study, we used next-generation sequencing to facilitate the generation of complementary data in order to analyze human evidence obtained through short tandem repeat (STR) analysis. We examined the applicability and potential of analyzing microbial genome communities. Microbiological supplementation information was confirmed for two of four failed STR samples. Additionally, the accuracy of the gargle sample was confirmed to be as high as 100% and was highly likely to be classified as a body fluid sample. Our experimental method confirmed that anthropological and microbiological evidence can be obtained by performing two experiments with one extraction. We discuss the advantages and disadvantages of using these techniques, explore prospects in the forensic field, and highlight suggestions for future research.
Feasibility Study of Multi Objective Shape Optimization for Rocket Engine Turbopump Blade Design

JAXA is now planning to develop a next generation booster engine named LE-X, which is a successor of LE-7A. From an engine cycle study, the LE-X requires a relatively high efficiency turbopump. To achieve this requirement, a feasibility study of design optimization with generic algorithm was applied to the impeller and turbine blade shape. As the first step, single objective optimization was carried out on the impeller blade design, and the second one was a multi objective optimization on the turbine blade shape. It was concerned that optimization may not be effective in such a highly loaded component, however, each of the optimized result have shown improvement on performance. Especially, multi objective optimization can show tradeoff information for several important parameters, therefore, it can be said that such method is quite useful for the improvement or the developing of high efficiency turbopumps.
Physical Activity and Diet Quality: Effects on Cardiovascular Morbidity in Women with Turner Syndrome—Results from an Online Patient Survey

Turner syndrome (TS) is a rare chromosomal disease with increased cardiovascular morbidity and mortality. The aim of this study was to investigate the influence of physical activity and diet quality on cardiovascular morbidity in German TS women. An anonymous online questionnaire was established. The questionnaire was based on the 2020 WHO recommendations on physical activity and sedentary behaviour and included the 14-Item Mediterranean Diet Assessment Tool. In addition, TS patients were asked about existing cardiovascular conditions. In total, 83 TS women were included in the final analysis. The achievement of <600 Metabolic Equivalent-minutes per week for recreational activities was significantly associated with the presence of arterial hypertension (p = 0.006). High adherence to the Mediterranean diet was achieved by only 20.5% of TS subjects and tended to be inversely associated with the presence of lipid metabolism disorders (p = 0.063). Only 37.3% of TS participants received nutritional counselling. Given the increased cardiovascular risk, specific counselling for lifestyle optimisation may play an important role in the management of TS. Further studies are required to evaluate the effects of regular aerobic physical training and different nutritional programs on cardiovascular morbidity in TS.
SAMI: a low-frequency prototype for mapping and imaging of the seabed by means of synthetic aperture

The objective of the Synthetic Aperture Mapping and Imaging (SAMI) project was to develop and to test at sea a wide-band synthetic aperture sonar prototype, capable of providing high-resolution seafloor images together with bathymetry maps. This system used the motion of a physically small array in order to synthesize a longer array, providing images with an across-track resolution independent of both range and transmit frequency. Such systems are clearly very relevant to the high-precision long-range (low-frequency) imaging of the sea bottom. The project has led to the construction of a prototype tested at sea on several well-known areas for comparison with existing images and maps. These areas included several types of sea bottom, depths, and geological structures. The results obtained in real time, on-board ship, have shown the relevance of the proposed wide-band techniques. The many profiles produced have provided high-resolution images and maps of various seafloors. Interpretation by geologists showed that the system was capable of providing the same or finer detail than a deep-sea short-range, high-frequency system and maintained a higher resolution over a wider swath. The sea data processed have shown that the system provided maps with a cubic meter voxel. The resolution cell is constant over the whole range (50 to 2500 m) thanks to the dynamic focusing of the synthetic aperture. Postprocessing of a part of the data stored during the experiments has been carried out in the laboratory. This work has shown that techniques such as autofocusing can give an increase in resolution (i.e., gain in contrast and resolution of about 3 dB). The results displayed in the paper show the relevance of the techniques developed to the provision of a complete high-performance imaging tool for the oceanographic community.
The characterization of a clean room assembly process

This paper presents the findings of a cross-functional team that was in charge of putting in place the design guidelines for the future assembly line of the small form factor hard disk drives (HDD). Keeping in mind that the factors affecting the characterization of an assembly process depend greatly on the nature of the product, the market forecast for the product, the production geographical location and many other local and special constraints. However, we believe that a similar approach to the one reported in this paper can yield an acceptable set of measurements that can help the product development teams present more manufacturable products. The core of our work was based on a quality function deployment (QFD) approach that included the construction of a house of quality. In addition to the findings of the team, we describe the progressive stages that had to take place from gathering the factory customers' wants and needs to organizing the cross functional team. We started with internal customers' needs for the ideal HDD manufacturing process. Our internal customers represented manufacturing operators, process engineers, product developers and managers for all three groups. With a large group of participants from dependent functions that included cleaning, testing, assembly, product technology, manufacturing engineering and others, we derived the clean room assembly process characteristics that are measurable and controllable to address our internal customers' needs.
Spectrum Allocation and Computing Resources Optimization for Demand-Side Cooperative Communications in Smart Grid

In this paper, we introduce edge computing technologies (ECT) to improve the quality of smart grid demand-side communications and simultaneously optimize bandwidth along with computing power resources, further reducing the costs to the utility company (UC). First, we employ the edge node (EN) with data computing capability as relay, meanwhile, constructing a analytical model of computing resources and bandwidth. Second, the electricity costs is built based on the packet loss model and the regulation errors in direct load control. Then the UC decides the computing resources and the bandwidth for relaying to minimize its total costs, and the EN sets the base price to maximize its profit. Furthermore, we consider the interactions between the UCs and the ENs as a Stackelberg game. Simulation results demonstrate a significant reduction in costs to the utility company and an exaltation in profits of the relays.
Physical wave propagation modeling for real-time synthesis of natural sounds

This thesis proposes banded waveguide synthesis as an approach to real-time sound synthesis based on the underlying physics. So far three main approaches have been widely used: digital waveguide synthesis, modal synthesis and finite element methods. Digital waveguide synthesis is efficient and realistic and captures the complete dynamics of the underlying physics but is restricted to instruments that are well-described by the one-dimensional string equation. Modal synthesis is efficient and realistic yet abandons complete dynamical description and hence cannot used for certain types of performance interactions like bowing. Finite element methods are realistic and capture the behavior of the constituent physical equations but on current commodity hardware does not perform in real-time. Banded waveguides offer efficient simulations for cases for which modal synthesis is appropriate but traditional digital waveguide synthesis is not applicable. The key realization is that the dynamic behavior of traveling waves, which is being used in waveguide synthesis, can be applied to individual modes and that the efficient computational structure can be utilized to achieve an approximate dynamical description in the neighborhood of modes. Secondly this realization is connected to related work on the theory of asymptotics and periodic orbits and hence shown to apply to higher dimensions also. This theoretical approach is studied in applications to bowed bar percussion instruments, complex stroke patterns on Indian Tabla drums as well as rubbed wine glasses and Tibetan singing bowls. None of these instruments and performance types has been synthesized efficiently before. The simulations are compared to experiments.
Development of Emotional Competencies as a Teaching Innovation for Higher Education Students of Physical Education

The objective of the work presented is to develop emotional competencies in higher-education students by following Bisquerra’s five-block model. With the methodological support of adventure pedagogy and gamification, students improve their emotional competencies, as well as the basic competencies of the degree in Physical Activity and Sport Sciences and the specific ones of the subject. The proposal, which is entitled “In search of my Avatar”, aims to make sure that, in their future as sports professionals, they will be able to serve their customers in a fully competent way. The work presented proposes different activities of emotional education to work transversally in higher education, ranging from conflict management and the use of language to improve the relationship with oneself and with others. The proposal was developed for the Degree in Sports Science and for the subject of Physical Activity and Sport in the Natural Environment, but with certain adaptations, it could be transferred to any university-degree subject.
Partial Nephrectomy in theManagement of Small Renal Masses

Introduction. Most of the kidney masses are being detected incidentally with smaller size due to widespread use of imaging modalities leading to increased RCC incidence worldwide with an earlier stage. This article reviews the role of open partial nephrectomy (PN) in the management of small renal masses. Material and Methods. Review of the English literature using MEDLINE has been performed between 1963–2008 on small renal masses, partial nephrectomy, kidney cancer, nephron sparing surgery (NSS), radical nephrectomy, laparoscopy, and surgical management. Special emphasis was given on the indications of NSS, oncological outcomes and comparison with open and laparoscopic PN. Results. Overall 68 articles including 31 review papers, 35 human clinical papers, 1 book chapter, and 1 animal research study were selected for the purpose of this article and were reviewed by the authors. Conclusions. Currently, open NSS still remains as the gold standard surgical treatment modality in patients with small renal masses.
Spin Polarization Oscillations without Spin Precession: Spin-Orbit Entangled Resonances in Quasi-One-Dimensional Spin Transport

Resonant behavior involving spin-orbit entangled states occurs for spin transport along a narrow channel defined in a two-dimensional electron gas, including an apparent rapid relaxation of the spin polarization for special values of the channel width and applied magnetic field (so-called ballistic spin resonance). A fully quantum mechanical theory for transport through multiple subbands of the one-dimensional system provides the dependence of the spin transport on the applied magnetic field and channel width, including a resonant depolarization of spins when the Zeeman energy matches the subband energy splittings and a spin texture transverse to the magnetic field. The resonance phenomenon is robust to disorder.

The aim is to extract information from documents usually producedand that are not used because of their special nature. The work is carried out withinthe European project BLUE-ETS, which aims to provide tools for the constructionof robust and high quality ofﬁcial statistics for businesses.
Chaotic Processes of Common Stock Index Returns: An Empirical Examination on Istanbul Stock Exchange (ISE) Market

The nonlinearity and accompanying concept, namely the chaos receive great attention from researchers. This study employs nonlinearity and chaos theories to examine the behavior of the Istanbul Stock Exchange (ISE) all share equity indices. The main purpose was to explore the existence or nonexistence of nonlinearity and chaotic behavior in the ISE market. Therefore, the efficient markets' characteristics, which are the random behavior of asset prices and nonlinear chaotic dynamics, were contrasted and the probabilistic and deterministic behaviors of the asset prices were compared. Our results based on BDS, Hinich Bispectral, Lyapunov Exponent and NEGM tests reject the efficient market hypothesis that the index series examined in this study is not random, independent and identically distributed (i.i.d).
The Diagnostic and Therapeutic Potential of Galectin-3 in Cardiovascular Diseases

Galectin-3 plays a prominent role in chronic inflammation and has been implicated in the development of many disease conditions, including heart disease. Galectin-3, a regulatory protein, is elevated in both acute and chronic heart failure and is involved in the inflammatory pathway after injury leading to myocardial tissue remodelling. We discussed the potential utility of galectin-3 as a diagnostic and disease severity/prognostic biomarker in different cardio/cerebrovascular diseases, such as acute ischemic stroke, acute coronary syndromes, heart failure and arrhythmogenic cardiomyopathy. Over the last decade there has been a marked increase in the understanding the role of galectin-3 in myocardial fibrosis and inflammation and as a therapeutic target for the treatment of heart failure and myocardial infarction.

Shipboard applications of wireless personal communication services (PCS)

This paper describes a wireless PCS trial conducted onboard the USS Saipan (LHA-2). To evaluate PCS in a typical shipboard environment, a wireless PBX system was installed, tested, and operated for a trial period on a Navy LHA class ship. This project began with a survey of candidate PCS systems, whereby a commercially available system was selected that offered cellular-based service, operating in either an internal mode for shipboard communications or in an external mode for ship to shore connectivity . Initial design and testing focused on propagation and interference effects on board two Navy ships, the USS Eisenhower and the USS Saipan. Based on these tests and further analysis, installation was completed on the USS Saipan and an operational trial period commenced. Besides the initial design and testing, other key items for evaluation during the trial period included traffic collection, performance monitoring, and user feedback. Several technical and procedural issues arose during the design and operational periods that are also addressed in this paper. The paper concludes with an assessment of the trial results and gives recommendations for further work and applications of PCS in a shipboard environment.
