Leaky-Wave Analysis of TM-, TE-, and Hybrid-Polarized Aperture-Fed Bessel-Beam Launchers for Wireless-Power-Transfer Links

Bessel beams (BBs) can be generated at microwave frequencies by means of compact, planar devices based on Fabry–Perot cavity leaky-wave resonators. Most designs are based on the excitation of a single transverse magnetic/transverse electric (TM/TE) leaky mode by means of a vertical electric/magnetic dipole source. In this work, we analyze the important case of a horizontal magnetic dipole, which excites both TM and TE modes, developing an original theoretical framework suitable for resonant radiators. Analytical expressions are provided for the dominant leaky-wave aperture field. The near-field distribution is then evaluated through an accurate numerical integration of the radiating currents and validated through full-wave simulations for the relevant case of a BB launcher when excited by a waveguide-fed slot. Different designs are presented and analyzed in order to obtain TM, TE, and hybrid polarizations, finding in all cases an excellent agreement between simulations and theoretical results. Finally, we evaluate and compare the wireless-power-transfer efficiency of two coupled TM-, TE-, or hybrid-polarized BB launchers when a wireless link is established in the radiative near-field region. Interestingly, full-wave results demonstrate the superior performance of resonant BB launchers in TM or TE polarization with respect to the nonresonant hybrid case.
Facts in Context: Problem Perceptions, Numerical Information, and Policy Attitudes

How does policy-relevant information change citizens’ policy attitudes? Though giving numerical information about social conditions has been found, at times, to change policy attitudes, why it works (or doesn’t) is poorly understood. I argue new or corrective information may not translate into policy-attitude change in part because it fails to instill a sense of need for change. Perceived problem seriousness, an affect-laden judgment about the acceptability of the status quo, may therefore be an important psychological mechanism through which information changes people’s minds. To perceive a problem, conditions must seem worse than they ought to be. Previous research, however, presents numerical information without a point of reference from which citizens can base their judgments. By contextualizing facts with reference points from the past (time) as well as other countries (space), four survey experiments show that numerical information about a range of social problems can change policy attitudes by first changing their perceived seriousness.
Association between Teachers’ Selflessness and School Organizational Commitment

This study aimed to determine the relationship between teachers' selflessness on their school organizational commitment. The study employed a descriptive-correlation research design with the online survey as the primary data collection tool. The respondents came from the 30 elementary and secondary schools in the Schools Division Office, Central Luzon. One hundred fifty-one public school teachers participated in the online survey using a stratified sampling technique. Adapted questionnaires were used to gather data. For the statistical treatment of the study, the mean was used for the teachers' responses. In contrast, for the relationship, the study used Pearson r-correlation. The study found that teachers' selflessness described their philosophies as "agree. " As for the teachers' organizational commitment, it generated moderate to high responses. There is a significant difference in teachers' selflessness regarding sex and position. Also, the study found a relationship between teachers' selflessness, and affective and continuance commitment aspects of teachers' organizational commitment. Based on the results mentioned above, the researcher provided some crucial recommendations for the study.
The Effectiveness of Direct and Metalinguistic Written Corrective Feedback to Deal With Errors in the Use of Information-Structuring Connectors

Background. Writing is a complex skill, even more so, if the student does not handle the generic structure of the institutionalized practices imposed on Higher Education. Purpose. The purpose of this study is to determine the effectiveness of direct and metalinguistic focused written corrective feedback (WCF) on information structuring connectors. Methods. This quantitative study compares focused WCF effectiveness in 39 subjects who are divided into three groups: the first one is the control group, which did not receive feedback, the second is the experimental group 1 that was corrected through direct WCF and the third one corresponds to experimental group 2 that received feedback through metalinguistic cues. Results. The findings indicate that WCF is effective for the experimental groups. There is a significant decrease in the number of errors of information-structuring connectors in experimental group 2, while experimental group 1 shows a reduction, but without statistical significance. As for the control group, it did not present improvements. In addition, the development of writing tasks corrected through metalinguistic WCF strategies led to textual cohesion improvement with the accurate use of connective devices. Conclusions. It is important to reflect on the use of focused feedback as part of the writing process, firstly, because writing cannot be taught without reviewing a student's writing, and secondly, considering that focused feedback supports the noticing of errors and decreases teacher correction time.
Small-Area Geographic and Socioeconomic Inequalities in Colorectal Cancer in Cyprus

Colorectal cancer (CRC) is one of the leading causes of death and morbidity worldwide. To date, the relationship between regional deprivation and CRC incidence or mortality has not been studied in the population of Cyprus. The objective of this study was to analyse the geographical variation of CRC incidence and mortality and its possible association with socioeconomic inequalities in Cyprus for the time period of 2000–2015. This is a small-area ecological study in Cyprus, with census tracts as units of spatial analysis. The incidence date, sex, age, postcode, primary site, death date in case of death, or last contact date of all alive CRC cases from 2000–2015 were obtained from the Cyprus Ministry of Health’s Health Monitoring Unit. Indirect standardisation was used to calculate the sex and age Standardise Incidence Ratios (SIRs) and Standardised Mortality Ratios (SMRs) of CRC while the smoothed values of SIRs, SMRs, and Mortality to Incidence ratio (M/I ratio) were estimated using the univariate Bayesian Poisson log-linear spatial model. To evaluate the association of CRC incidence and mortality rate with socioeconomic deprivation, we included the national socioeconomic deprivation index as a covariate variable entering in the model either as a continuous variable or as a categorical variable representing quartiles of areas with increasing levels of socioeconomic deprivation. The results showed that there are geographical areas having 15% higher SIR and SMR, with most of those areas located on the east coast of the island. We found higher M/I ratio values in the rural, remote, and less dense areas of the island, while lower rates were observed in the metropolitan areas. We also discovered an inverted U-shape pattern in CRC incidence and mortality with higher rates in the areas classified in the second quartile (Q2-areas) of the socioeconomic deprivation index and lower rates in rural, remote, and less dense areas (Q4-areas). These findings provide useful information at local and national levels and inform decisions about resource allocation to geographically targeted prevention and control plans to increase CRC screening and management.
Two new goodness‐of‐fit indices for covariance matrices with linear structures

Two new indices each based on two different methods of estimating the population covariance matrix Σ are derived. Certain algebraic results on these indices are also reported. A case study has been presented to show how the proposed indices in comparison to Joreskog-Sorbom's GFI are more efficient in detecting the ‘best’ structure out of 13 competing structures hypothesized for the Graduate Record Examination data. Algebraically it has also been shown that the limiting value of GFI fails to reach the desired value of zero under model misspecification. A Monte Carlo study also shows that with increasing sample size the proposed indices as compared to others show more and more sensitivity to model misspecification. Other advantages of the indices as measures of structural closeness of Z to S are discussed.

Finite element analysis to assess stress and deformation in bone with glass fiber-reinforced-poly-ether-ether-ketone, zirconia, and titanium implants

Objectives: Recently, zirconia ceramic and glass or carbon fiber-reinforced poly-ether-ether-ketone (PEEK) composites have been introduced as newer implant biomaterials. This study was done to evaluate stress and deformation in bone with glass fiber-reinforced (GFR)-PEEK, zirconia, and titanium implants. Materials and Methods: A geometric model of mandibular molar replaced with implant-supported crown was generated. Implant of 12 mm length and 4.5 mm diameter was used in study. Finite element analysis models of implant assemblies of three materials GFR-PEEK, zirconium, and titanium were generated. 150 N loads were applied obliquely and vertically along the long axis of implant. Von Mises stresses and deformation generated were compared using ANSYS Workbench 17.0 and finite element software. Results: All three implant assemblies, i.e., GFR-PEEK, zirconia, and titanium, demonstrated similar stresses and deformation in bone without significant difference. Conclusion: It was concluded that GFR-PEEK and zirconia implants can be used as a substitute to titanium implants.
Condorcet Social Choice Functions

A Condorcet social choice function elects the candidate that beats every other candidate under simple majority when such a candidate exists. Various extensions of Condorcet’s simple majority principle that deal with situations that have no simple majority winner have been proposed.Nine Condorcet social choice functions are analyzed and compared on the basis of how well they satisfy a number of conditions for social choice functions. The conditions include several generalizations of Condorcet’s Principle. Remarks on the relative merits of the nine basic functions are included.
Effect of Emulsion Particle Size on the Encapsulation Behavior and Oxidative Stability of Spray Microencapsulated Sweet Orange Oil (Citrus aurantium var. dulcis)

Three different feed emulsions of different particle sizes were mixed with a modified starch and maltodextrin and spray dried to make a large (LP), small (SP), and nano-size encapsulated powder (NP), respectively. Emulsion size, oil content, loading capacity (LC), encapsulation efficiency (EE), water content, aw, scanning electron microscopy (SEM), glass transition temperature (Tg), as well as d-limonene release characteristic and limonene oxide formation rate during 37 °C and various aw storage were determined. With the increase of the feed emulsion size, the reconstituted emulsion size of the LP tended to increase and change to a bimodal distribution. The surface oil content increased with the increasing size of the reconstituted emulsion, and the opposite was true for EE. The smaller the reconstituted emulsion size, the higher Tg during a low aw condition. The Tg of the LP, SP and NP were 62, 88, and 100 °C, respectively, and NP > SP > LP. The release and the oxidative rate of d-limonene was the lowest for the NP and then increased for the SP and LP. The release and oxidative rates increased with the elevation of aw and peaked at 0.33. The powder surface morphological structure was intact, the spray-dried powder was more stable, and microstructure changed from a glass state to a rubbery state during storage.
Anisotropic MHD model of the dayside magnetosheath downstream of the oblique bow shock

Large-scale flow in the dayside magnetosheath is calculated by using a three-dimensional anisotropic MHD model for the case when the angle between the interplanetary magnetic field and the solar wind velocity is 45°. The behavior of plasma and magnetic field parameters downstream of the quasi-perpendicular and quasi-parallel bow shocks is compared in the results from a single calculation. The model includes a limit on the proton temperature anisotropy based upon thresholds for onset of the ion cyclotron and mirror instabilities. Results are presented for three different values of the isotropization rate. The model shows the existence of the plasma depletion layer, corresponding to an increase of the magnetic field intensity and a decrease of the plasma density near the magnetopause, for all angles of the bow shock normal relative to the interplanetary magnetic field. There is a thin layer downstream of the quasi-parallel shock where T‖p > T⊥p. The magnetosheath regions are shown where the threshold conditions for ion cyclotron and mirror instabilities are satisfied.
Gut microbiome signatures reflect different subtypes of irritable bowel syndrome

ABSTRACT Irritable bowel syndrome (IBS) is a heterogeneous condition with multifactorial pathogenesis. We studied deeply phenotyped individuals with microbiota sequencing enrolled in the American Gut Project. The IBS subjects were matched by age, gender, body mass index, geography, and dietary patterns with non-IBS controls. A total of 942 subjects with IBS-Diarrhea (IBS-D), IBS-Constipation (IBS-C), unclassified IBS (IBS-U), and 942 non-IBS controls were included. We compared taxonomic and functional composition of gut microbiota based on 16S sequencing data and linked them with clinical characteristics and dietary factors. Subjects with IBS-D or IBS-U but not IBS-C showed significantly reduced bacterial diversity (Shannon; p < .01). Distinct bacterial signatures were associated with different IBS subtypes, and the related functional changes were related to IBS pathogenesis, such as the increased hydrogen sulfide production pathway in IBS-D and the increased palmitoleate biosynthesis pathway in IBS-C. IBS subjects with depression showed lower abundance of Bifidobacterium, Sutterella, Butyricimonas and higher abundance of Proteus than those without depression. The relative abundance of microbial short-chain fatty acid production pathways was significantly lower in IBS patients with depression than those without depression in all three subtypes. Female, younger age in IBS-D, and older age in IBS-C were associated with more severe microbiota dysbiosis, and distinct dietary factors had significant effects on the gut microbiota in different IBS subtypes. Our analysis identified the compositional uniqueness of gut microbiota in different IBS subtypes. Distinct associations of the gut microbiota with depression in IBS provide insights into shared pathways in disease pathogenesis. These findings highlight the importance of personalized gut microbiome modulation approaches in different subtypes for optimal therapeutic effects.

Isolated Hot Stars in the Galactic Center Vicinity

Using near-infrared imaging and spectroscopy, we discuss the discovery of six emission-line sources within ~20 pc of Sgr A West but outside of the central parsec. The objects are coincident with stars seen in the J, H, and K' images; all have Brγ (2.166 μm) in emission, several also have He I (2.058 and 2.112/3 μm), and some have He II (2.189 μm) emission lines. Comparison of the H- and K-band spectra of the newly discovered stars with recently published infrared spectral atlases of optically classified stars suggests that most of these stars are similar to massive stars in transition (e.g., Ofpe/WN9, B[e], and LBV), although one is definitely a WN6 star. Two of the potential stars are associated with the radio emission regions A-D near Sgr A East, three are near or within the radio emission regions H1-H8 (nomenclature from Yusef-Zadeh & Morris), the last is near G0.10+0.02 and is likely to be associated with the G0.12+0.02 (Arches) cluster of stars, discussed in a previous paper. The stars are shown to be significant sources of ionization for their associated radio emission regions, with several capable of completely ionizing the regions. These results provide additional support for the idea that these thermal radio regions, and similar such regions in the Galactic center, are indeed photoionized by hot young stars.
Two Multiplex PCR Methods for Detecting Several Pathogens Associated with Feline Respiratory and Intestinal Tracts

Simple Summary Coinfection with multiple pathogens is common among feline respiratory tract and intestinal diseases. In clinical cases, cats may exhibit similar symptoms between respiratory and intestinal disease, making it difficult to accurately identify and distinguish pathogens. This study aimed to establish two novel multiplex polymerase chain reactions (mPCRs) for simultaneous detection of pathogens associated with the feline respiratory and intestinal tracts. Regrading sensitivity, the detection limits for FeKoV, FPV, FeAstV, FCoV, IAV, C. felis, FeLV, FHV-1 and FCV were 103, 104, 103, 103, 103, 104, 104, 105 and 105 copies/µL, respectively. Moreover, the specificity of the two mPCRs was high. In summary, the two newly mPCR methods provide available, specific, sensitive and inexpensive tools for detecting pathogens. Abstract Respiratory tract and intestinal diseases are common threats to feline health. Coinfection with multiple pathogens is not rare among clinical infectious cases. Rapid diagnosis of these coinfections is of great significance for timely and effective clinical treatment. In this study, two novel multiplex polymerase chain reactions (mPCRs) were established for simultaneous detection of four pathogens associated with the feline intestinal tract (feline coronavirus (FCoV), feline astrovirus (FeAstV), feline panleukopenia virus (FPV) and feline kobuvirus (FeKoV)) and five pathogens associated with the respiratory tract (feline calicivirus (FCV), feline herpesvirus 1 (FHV-1), feline leukemia virus (FeLV), Chlamydia felis (C. felis) and influenza A virus (IAV)). The results of sensitivity analysis revealed that the detection limits for FeKoV, FPV, FeAstV, FCoV, IAV, C. felis, FeLV, FHV-1 and FCV were 103, 104, 103, 103, 103, 104, 104, 105 and 105 copies/µL, respectively. Moreover, the specificity of the two mPCRs was high. When the two mPCRs were applied to clinical samples, the assay worked well. In conclusion, we established two mPCR methods that provide an excellent tool for the diagnosis and monitoring of pathogens associated with the feline respiratory and intestinal tracts.
An illustration of the link between ribs and hyperbolic instability

The hyperbolic instability in planar Taylor–Green cells is investigated by direct numerical simulations at Reynolds number 400. The mechanism of this three-dimensional instability is a stretching of the vorticity perturbation along the principal axis of strain in accordance with well-known results of rapid distortion theory and stability analysis, leading to the formation of spanwise counter-rotating vortices (or ribs) in the irrotational hyperbolic stagnation point regions, as described by Kerr and Dold [J. Fluid Mech. 276, 307 (1994)].
A Comparison of PET Tracers in Recurrent High-Grade Gliomas: A Systematic Review

Humans with high-grade gliomas have a poor prognosis, with a mean survival time of just 12–18 months for patients who undergo standard-of-care tumor resection and adjuvant therapy. Currently, surgery and chemoradiotherapy serve as standard treatments for this condition, yet these can be complicated by the tumor location, growth rate and recurrence. Currently, gadolinium-based, contrast-enhanced magnetic resonance imaging (CE-MRI) serves as the predominant imaging modality for recurrent high-grade gliomas, but it faces several drawbacks, including its inability to distinguish tumor recurrence from treatment-related changes and its failure to reveal the entirety of tumor burden (de novo or recurrent) due to limitations inherent to gadolinium contrast. As such, alternative imaging modalities that can address these limitations, including positron emission tomography (PET), are worth pursuing. To this end, the identification of PET-based markers for use in imaging of recurrent high-grade gliomas is paramount. This review will highlight several PET radiotracers that have been implemented in clinical practice and provide a comparison between them to assess the efficacy of these tracers.
The Difference in Zinc Concentrations Required for Induction among Metallothionein Isoforms Can Be Explained by the Different MTF1 Affinities to MREs in Its Promoter

Metallothioneins (MTs) are cysteine-rich low-molecular-weight proteins that protect cells from heavy metal toxicity. MT1 and MT2 are considered ubiquitously expressed among the MT isoforms ranging from 1 to 4. These MT1 and MT2 transcriptions are regulated by metal regulatory transcription factor 1 (MTF1) binding to the metal response element (MRE) of the promoter, which is upregulated in response to zinc. The functional MT isoforms are MT1A, MT1B, MT1E, MT1F, MT1G, MT1H, MT1M, MT1X, and MT2A in humans, but these expressions were differently regulated. Here, MT1A was shown to be significantly less upregulated by zinc than MT1E, MT1G, MT1X, and MT2A. The poor responsiveness of the MT1A zinc was suggested to be due to the MRE sequence in the MT1A promoter region having a lower MTF1 binding affinity compared to the other isoforms. MT1A may be induced via pathways other than the MTF1–MRE binding pathway. These findings may help elucidate the differential regulation of MT isoform expression.
