Three estimation methods with robust corrections-maximum likelihood (ML) using the sample covariance matrix, unweighted least squares (ULS) a polychoric correlation and diagonally weighted (DWLS) matrix-have been proposed in literature, are considered to be superior normal theory-based maximum when observed variables latent variable models ordinal. A Monte Carlo simulation study was carried out compare performance of ML, DWLS, ULS estimating model parameters, their corrections standard...

This paper presents a methodology of exciting pure circular TE <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">mn</sub> modes using cascaded Y-type power dividers. The dividers partition the input signal into several parts, which are then coupled to waveguide through apertures. coupling apertures induce magnetic dipoles. With proper arrangement dipoles on circumference waveguide, they jointly excite desired mode. strength and mode purity...

Inferences about student learning from large-scale achievement test scores are fundamental in education. For to provide useful information progress, differences the content of instruction (i.e., implemented curriculum) should affect test-takers’ item responses. Existing research has begun identify patterns instructionally sensitive multiple-choice items. To inform future design decisions, this study identified (in)sensitive constructed-response items, then characterized features those items...

Nurses play an indispensable role in healthcare teams. The quality of nursing care reflects nurses' ability to integrate and their overall performance patient care, making it a core objective clinical nursing. Chinese version the Quality Nursing Care (QNC) scale is multidimensional assessment tool used for self-evaluation holds significant importance practice. This study aimed assess reliability validity QNC among nurses. was observational, cross-sectional, methodological conducted at three...

Emotion regulation has been considered a vital mechanism for psychological and physical health. The Regulation Questionnaire (ERQ) was originally developed by Gross John to measure the emotion strategies of cognitive reappraisal expressive suppression. Given practical importance functional assessment in Taiwanese cultural context, this study examined psychometric properties Chinese version ERQ sample 909 college students. Results showed that independent two-factor measurement model an...

Crystalline structures, intrinsic stress, and surface roughness of piezoelectric ZnO films deposited on sapphire substrates by rf magnetron sputtering sequential post-annealing treatments were investigated X-ray diffraction (XRD) atomic force microscopy (AFM) measurements. The power used O2/(Ar+O2) gas ratio greatly affected the crystallinity film. A c-axis preferred orientation with superior was achieved at a specific flow ratio. In addition, original stress also markedly released...

In the field of computer vision, local binary pattern (LBP) is one most popular feature extraction method and has been used in many object detection frameworks. To efficiently extract LBP features high-resolution images, hardware architecture needed to disperse CPU burden improve entire performance. this paper, a implementation an approximated with adjustable parameters introduced. For simulation, Taiwan Semiconductor Manufacturing Company <inline-formula...

Studies of neutrinos commonly ignore anti-symmetrization their wave functions. This implicitly assumes that either spatial functions for with approximately the same momentum do not overlap or overlapping has no measurable consequences. We examine these assumptions by considering evolution three-dimensional neutrino packets (WPs). find it is perfectly adequate to treat accelerator and reactor as separate WPs typical experimental setup. While solar supernova correspond WPs, they can be treated...

The fulfillment of measurement invariance/equivalence is considered a prerequisite for meaningfully proceeding with substantive cross-group comparisons. In the multiple-group confirmatory factor analysis approach, one model identification issue has unfortunately received little attention: specification referent variable in test invariance. A multiple-indicator multiple-cause (MIMIC) moderated effects (i.e., MIMIC-interaction modeling; Woods & Grimm, 2011) and nonlinear (MNLFA; Bauer, 2017)...
