Multifunction Pattern Reconfigurable Slot-Antenna for 5G Sub-6 GHz Small-Cell Base-Station Applications

A new compact multifunctional pattern reconfigurable <inline-formula> <tex-math notation="LaTeX">$2\times 2$ </tex-math></inline-formula> antenna array at 3.65 GHz with high gain and 16 (Multiple Input Multiple Output) MIMO modes is proposed. The single-element antenna includes 4 U-slots etched on the ground plane, with orthogonal slot orientations for polarization un-correlation, and fed using a reconfigurable feeding network with 4 PIN diodes. Hence, the single-element antenna is a pattern reconfigurable U-slot antenna with four pattern configurations. The average efficiency of 80%, the peak gain of 9.4 dB, and an overlapped −10 dB impedance-bandwidth of 200 MHz at a resonant frequency of 3.65 GHz in the n78 5G band are achieved. The single-element size is <inline-formula> <tex-math notation="LaTeX">$55.5\times 54$ </tex-math></inline-formula> mm<sup>2</sup>, <inline-formula> <tex-math notation="LaTeX">$0.66 \lambda _{0} \times 0.65 \lambda _{0}$ </tex-math></inline-formula>. The horizontal and vertical distances between the U-slots in a single-element are 30 mm <inline-formula> <tex-math notation="LaTeX">$(0.36\lambda _{0})$ </tex-math></inline-formula>, and 27 mm <inline-formula> <tex-math notation="LaTeX">$(0.32\lambda _{0})$ </tex-math></inline-formula>, respectively. The <inline-formula> <tex-math notation="LaTeX">$2\times 2$ </tex-math></inline-formula> antenna array of such an element with a 58.5 mm <inline-formula> <tex-math notation="LaTeX">$(0.7\lambda _{0})$ </tex-math></inline-formula> between the elements occupies a volume of <inline-formula> <tex-math notation="LaTeX">$140\times 140\times 21$ </tex-math></inline-formula> mm<sup>3</sup>. The <inline-formula> <tex-math notation="LaTeX">$2\times 2$ </tex-math></inline-formula> elements provide 16 reconfigurable U-slots with two modes of operation, Array Mode and Multiple-Input-Multiple-Output (MIMO) Mode. For the MIMO Mode, the antenna has a maximum Envelope Correlation Coefficient (ECC) of 0.1194 between the radiation patterns and a minimum isolation of 20 dB between the four ports. For the array Mode, a <inline-formula> <tex-math notation="LaTeX">$4\times 4$ </tex-math></inline-formula> antenna array has a peak gain of 17 dBi, and a beam-steering range of <inline-formula> <tex-math notation="LaTeX">$-50^{\circ} \leq \theta \leq 50^{\circ} $ </tex-math></inline-formula> in the two principle planes. The antenna is suitable for small cell base-station applications.
Factors Affecting Learner Motivation in Physical Science at a Public School in the Gauteng Province: The Teacher’s Role

Abstract South Africa lags behind in terms of competing globally in science and technology. Thus, the purpose of the study was to investigate teacher factors that influenced learners’ motivation to learn science in a secondary school. The study also aimed to determine whether significant differences in motivation regarding teacher influence existed among age groups and genders. The research was conducted in a public secondary school in Gauteng province, South Africa with 462 learners from Grade 8 to Grade 11. Using a quantitative approach, the learners completed a questionnaire that involved several motivation constructs (mastery and performance goal oriented). The study identified some problems that could impact on learner motivation and also found that some significant differences existed among different grades and genders. A number of recommendations were made regarding the teacher’s role in motivating science learning.
Testing a Eudaimonic Theory of Goal Hierarchy

of a dissertation at the University of Miami. Dissertation supervised by Professor Blaine Fowers. No. of pages in text. (121) This study utilized Eudaimonic Theory (ET), an Aristotelian perspective on human flourishing (eudaimonia), to explore new eudaimonic goal hierarchy hypotheses. The ET model distinguishes between two types of well-being: Eudaimonic Well-Being (EWB) and Hedonic Well-Being (HWB), and two dimensions of goal pursuit: the Communal Dimension and the Agency Dimension. HWB refers to experiencing high positive affect, low negative affect and high life satisfaction. EWB is assessed through factors such as purpose, personal growth and positive relationships giving. The Communal Dimension refers to a distinction between individual goals, which can only be pursued by one person and shared goals, which are completely collective accomplishments. The Agency Dimension refers to a distinction between Instrumental Goals, in which the means and ends are separable, and Constitutive Goals, in which means constitute the ends. This study used SEM and was the first to empirically test Agency, Communion, and WellBeing relationships simultaneously. Extending earlier findings, EWB related to both Instrumental and Constitutive Goal Pursuit for Interpersonal Goals; while for Individual Goals, HWB related to Instrumental and Constitutive Goal Pursuit. Shared Goal Orientation significantly related to HWB for Individual Goals but not to EWB for Interpersonal Goals. Contrary to hypothesis, Shared Goal Orientation did not augment the relationships between either Instrumental Goal Pursuit and HWB, or Constitutive Goal Pursuit and EWB. Results suggest that Agency and Communion have some additive but no multiplicative effects on Well-Being
Reliability Bounds based on Universal Generating Function and Discrete Stress-strength Interference Model

A method for estimating the component reliability is proposed when the probability density functions of stress and strength can not be exactly determined. For two groups of finite experimental data about the stress and strength, an interval statistics method is introduced. The processed results are formulated as two interval-valued random variables and are graphically represented by using two histograms. The lower and upper bounds of component reliability are proposed based on the universal generating function method and are calculated by solving two discrete stress-strength interference models. The graphical calculations of the proposed reliability bounds are presented through a numerical example and the confidence of the proposed reliability bounds is discussed to demonstrate the validity of the proposed method. It is showed that the proposed reliability bounds can undoubtedly bracket the real reliability value. The proposed method extends the exciting universal generating function method and can give an interval estimation of component reliability in the case of lake of sufficient experimental data. An application example is given to illustrate the proposed method.
Limit of Detection (LoD) Estimation Using Parametric Curve Fitting to PCR (Hit) Rate Data: The LoD_Est SAS Macro

The Limit of Detection (LoD) is defined as the lowest concentration or amount of material, target or analyte that is consistently detectable (for PCR quantitative studies, in at least 95% of the samples tested) 1 . In practice, the estimation of the LoD uses a parametric curve fit to a set of panel member (PM1, PM2, PM3, etc.) data where the responses are binary. Typically, the parametric curve fit to the percent detection levels takes on the form of a probit or logistic distribution. For this, the SAS PROBIT procedure can be used to fit a variety of distributions, including both the probit and logistic. We introduce the LOD_EST SAS macro that takes advantage of the SAS PROBIT procedure’s strengths and returns an information-rich graphic as well as a percent detection table with associated 95% exact (Clopper-Pearson) confidence intervals for the hit rates at each level. INTRODUCTION AND BACKGROUND For analytical sensitivity in a PCR assay, we would like to know the lowest amount of analyte we can reliably detect (typically taken as 95% of samples tested). This is important in the diagnosis and monitoring of target viruses (e.g., HBV, HCV, HIV)* or bacteria (e.g., Listeria, MAP, MRSA)**. For example, the analytical sensitivity of the assay test for the HIV-1 virus in the blood stream can be used to diagnose disease in a patient who is then placed on a drug treatment regimen. Subsequently, the viral load of the patient is monitored regularly to ensure the treatment is efficacious. For quantitative assays, the analytical sensitivity is measured by the limit of detection (LoD) and sometimes called the lower limit of detection (LLoD). For the remaining presentation, we use the more common LoD acronym and “sensitivity” to mean “analytical sensitivity”, as it relates to a quantitative assay, throughout this document. To begin, an experiment is performed that collects information about the lower end of the quantitative assay. Typically, several (panel) levels are targeted at the lower portion of the assay range (Table 1), where it may not be linear on the log10 response, in order to fit a parametric model curve to obtain an estimate of the LoD where the curve crosses 95% detection or hit rate (Figure 1). Operationally, the levels or panels in the experiment are chosen to include at least one panel member at 100% detection, another to anchor the parametric curve at the bottom end (not including zero) with the remaining three or more levels targeting the region where one believes the LoD might be located. Table 1 shows an example of six panel levels (not including zero) with the top end anchored by an HCV RNA assay level at 50 IU/mL and one anchor at the bottom at 2.5 IU/mL. There are four levels in between both the top and bottom ends: 25, 15, 10 and 5 IU/mL. Table 1.

New probes of Cosmic Microwave Background large-scale anomalies

Fifty years of Cosmic Microwave Background (CMB) data played a crucial role in constraining the parameters of the ΛCDM model, where Dark Energy, Dark Matter, and Inflation are the three most important pillars not yet understood. Inflation prescribes an isotropic universe on large scales, and it generates spatially-correlated density fluctuations over the whole Hubble volume. CMB temperature fluctuations on scales bigger than a degree in the sky, affected by modes on super-horizon scale at the time of recombination, are a clean snapshot of the universe after inflation. In addition, the accelerated expansion of the universe, driven by Dark Energy, leaves a hardly detectable imprint in the large-scale temperature sky at late times. Such fundamental predictions have been tested with current CMB data and found to be in tension with what we expect from our simple ΛCDM model. Is this tension just a random fluke or a fundamental issue with the present model? In this thesis, we present a new framework to probe the lack of large-scale correlations in the temperature sky using CMB polarization data. Our analysis shows that if a suppression in the CMB polarization correlations is detected, it will provide compelling evidence for new physics on super-horizon scale. To further analyze the statistical properties of the CMB temperature sky, we constrain the degree of statistical anisotropy of the CMB in the context of the observed large-scale dipole power asymmetry. We find evidence for a scale-dependent dipolar modulation at 2. 5σ. To isolate late-time signals from the primordial ones, we test the anomalously high Integrated Sachs-Wolfe effect signal generated by superstructures in the universe. We find that the detected signal is in tension with the expectations from ΛCDM at the 2. 5σ level, which is somewhat smaller than what has been previously argued. To conclude, we describe the current status of CMB observations on small scales, highlighting the tensions between Planck, WMAP, and SPT temperature data and how the upcoming data release of the ACTpol experiment will contribute to this matter. We provide a description of the current status of the data-analysis pipeline and discuss its ability to recover large-scale modes.
A Follow-Up Study on the Influence of Personal, Family, and School Factors on Learning Outcomes of Students with Disabilities in Senior High School

The purposes of this study were to describe the learning outcomes of students with disabilities in senior high school, to establish a model to explain the effects of personal, family, and school experience factors on the learning outcomes of students with disabilities, and to determine the relationship between post-school and in-school outcomes. There were 496 participants selected in the 2011 and 2012 academic year from the database of Special Needs Education Longitudinal Study. The survey data obtained from questionnaires for teachers, parents, and students were used to conduct secondary analysis. Descriptive statistics such as frequencies and percentages, a PLS structural equation model, and multiple regression were used in this study. The results of this study were as follows: (1) Students with disabilities had the best learning performances in school, and most parents were satisfied with their students’ education in school; however, employment performance was the weakest upon leaving school. (2) School experience factors had the greatest influence on the school learning outcomes model, followed by student factors and family factors. (3) In-school outcomes effectively predicted postsecondary education, employment, social adaptation, and satisfaction after leaving school. In conclusion, the results of this study found that personal, family, and school factors have a significant impact on the learning outcomes of students with disabilities, and in-school outcomes can effectively predict postsecondary education, social adaptation, and satisfaction after leaving school.
Polyethyleneimine modified spent coffee grounds as a novel bio-adsorbent for selective adsorption of anionic Congo red and cationic Methylene blue

Here, a new renewable bio-adsorbent (SCG-PEI) was prepared by grafting polyethyleneimine (PEI) onto spent coffee grounds (SCG) surface. Effects of molecular weight and dosage of PEI, initial dye concentration, contact time, temperature and pH on the adsorption properties of SCG-PEI adsorbent for Congo red (CR) were comprehensively researched. The SCG-PEI adsorbent possesses higher adsorption capacity towards CR when using PEI with higher molecular weight. Adsorption capacity of SCG-PEI to CR (1,313 mg/g) is better than Methylene blue (MB, 814 mg/g) owing to the high content of amino groups in SCG-PEI adsorbent that has a selective adsorption to CR. The spe- cific surface area of SCG-PEI sample is 18.336 m 2 /g, and the pore volume is 0.0169 cm 3 /g. Kinetic and isothermal analysis explored that the adsorption behavior of CR dye complies with Elovich kinetic model and Freundlich adsorption isotherm model. The adsorption mechanism further reveals that electrostatic force and pore filling are prominent effects for the higher adsorption of CR. The study provides an approach for preparing environmentally friendly and efficient adsorbents.
Accurate identification and discrimination of Salmonella enterica serovar Gallinarum biovars Gallinarum and Pullorum by a multiplex PCR based on the new genes of torT and I137_14430

Most cases of chicken salmonellosis are caused by Salmonella enterica serovar Gallinarum biovars Gallinarum and Pullorum, which lead to a significant morbidity and fatality rate. Although the conventional Kaufmann-White scheme is the reliable method for the serotyping of Salmonella, it does not distinguish between closely related biotypes like S. Pullorum and S. Gallinarum. Herein, we conducted a single one-step multiplex PCR assay that can identify and distinguish between S. Pullorum and S. Gallinarum in an accurate manner. This PCR method was based on three genes, including torT for S. Pullorum identification, I137_14430 for S. Gallinarum identification, and stn as the genus-level reference gene for Salmonella. By comparing S. Pullorum to S. Gallinarum and other serovars of Salmonella, in silico study revealed that only the former has a deletion of 126 bp-region in the carboxyl terminus of torT. The I137_14430 gene does not exist in S. Gallinarum. However, it is present in all other Salmonella serotypes. The multiplex PCR approach utilizes unique sets of primers that are intended to specifically target these three different genes. The established PCR method was capable of distinguishing between the biovars Pullorum and Gallinarum from the 29 distinct Salmonella serotypes as well as the 50 distinct pathogens that are not Salmonella, showing excellent specificity and exclusivity. The minimal amount of bacterial cells required for PCR detection was 100 CFU, while the lowest level of genomic DNA required was 27.5 pg/μL for both S. Pullorum and S. Gallinarum. After being implemented on the clinical Salmonella isolates collected from a poultry farm, the PCR test was capable of distinguishing the two biovars Pullorum and Gallinarum from the other Salmonella strains. The findings of the PCR assay were in line with those of the traditional serotyping and biochemical identification methods. This new multiplex PCR could be used as a novel tool to reinforce the clinical diagnosis and differentiation of S. Pullorum and S. Gallinarum, particularly in high-throughput screening situations, providing the opportunity for early screening of infections and, as a result, more effective management of the illness among flocks.
Changes in Documentation Due to Patient Access to Electronic Health Records: Protocol for a Scoping Review

Background Internationally, patient-accessible electronic health records (PAEHRs) are increasingly being implemented. Despite reported benefits to patients, the innovation has prompted concerns among health care professionals (HCPs), including the possibility that access incurs a “dumbing down” of clinical records. Currently, no review has investigated empirical evidence of whether and how documentation changes after introducing PAEHRs. Objective This paper presents the protocol for a scoping review examining potential subjective and objective changes in HCPs documentation after using PAEHRs. Methods This scoping review will be carried out based on the framework of Arksey and O’Malley. Several databases will be used to conduct a literature search (APA PsycInfo, CINAHL, PubMed, and Web of Science Core Collection). Authors will participate in screening identified papers to explore the research questions: How do PAEHRs affect HCPs’ documentation practices? and What subjective and objective changes to the clinical notes arise after patient access? Only studies that relate to actual use experiences, and not merely prior expectations about PAEHRs, will be selected in the review. Data abstraction will include but will not be limited to publication type, publication year, country, sample characteristics, setting, study aim, research question, and conclusions. The Mixed Methods Appraisal Tool will be used to assess the quality of the studies included. Results The results from this scoping review will be presented as a narrative synthesis structured along the key themes of the corpus of evidence. Additional data will be prepared in charts or tabular format. We anticipate the results to be presented in a scoping review at a later date. They will be disseminated at scientific conferences and through publication in a peer-reviewed journal. Conclusions This is the first scoping review that considers potential change in documentation after implementation of PAEHRs. The results can potentially help affirm or refute prior opinions and expectations among various stakeholders about the use of PAEHRs and thereby help to address uncertainties. Results may help to provide guidance to clinicians in writing notes and thus have immediate practical relevance to care. In addition, the review will help to identify any substantive research gaps in this field of research. In the longer term, our findings may contribute to the development of shared documentation guidelines, which in turn are central to improving patient communication and safety.

Alignment Design and Status of Taiwan Photon Source

The construction of Taiwan Photon Source (TPS) will be finished recently. The entire building was constructed half underground at the depth of up to 12 m relative to Taiwan Light Source (TLS) for stability reasons; for these reasons, the survey and alignment work is confined and difficult. To overcome the rigorous terrain, the network includes a preliminary Global Positioning System (GPS) network and a laser tracking network. The network needs to be maintained regularly during the construction and the temperature change. At the mean while, the magnets are installed on the datum plane of girders. To avoid the particles caused by the construction landing on the datum plane, the magnets of TPS were assembled on girders before it was moved to the construction site. The detailed survey and alignment design, variation of network, and the installation process are described in this paper.
Experiences of Hearing Parents of Children with Hearing Loss: A Qualitative Study

This qualitative study was carried out with a phenomenological design to determine the life experiences of the parents of children with hearing loss. The study sample consisted of twenty parents, who did not have hearing loss, of children with hearing loss registered in a special education and rehabilitation center. The data were collected through in-depth interviews in Istanbul between December and January 2022. Colaizzi’s phenomenological interpretation method was used for qualitative data analysis. It was determined that parents of children with hearing loss experienced anxiety, sadness, and happiness during diagnosis. They needed more information at first, but then they gained knowledge in the process, and it took work to accept this process. They stated that having a child with hearing loss requires more time, responsibility, and effort than other children. This situation affects their social life, and they experience interpersonal conflicts. When parents were asked how they coped, they said they did it through prayer, social support, or time to themselves. It can be recommended to apply psychosocial intervention programs to the parents of children with hearing loss, especially their mothers, from the first diagnosis process.
Droplet spreading and capillary imbibition in a porous medium: A coupled IB-VOF method based numerical study

We investigate the dynamics of a liquid droplet in contact with a surface of a porous structure by means of the pore-scale level, fully resolved numerical simulations. The geometrical details of the solid porous matrix are resolved by a sharp interface immersed boundary method on a Cartesian computational grid, whereas the motion of the gas-liquid interface is tracked by a mass conservative volume of fluid method. The numerical simulations are performed considering a model porous structure that is approximated by a 3D cubical scaffold with cylindrical struts. The effect of the porosity and the equilibrium contact angle (between the gas-liquid interface and the solid struts) on the spreading behavior, liquid imbibition, and apparent contact angle (between the gas-liquid interface and the porous base) are studied. We also perform several simulations for droplet spreading on a flat surface as a reference case. Gas-liquid systems of the Laplace number, La = 45 and La = 144 × 103 are considered neglecting the .
