Abstract The nEXO neutrinoless double beta (0 νββ ) decay experiment is designed to use a time projection chamber and 5000 kg of isotopically enriched liquid xenon search for the in 136 Xe. Progress detector design, paired with higher fidelity its simulation an advanced data analysis, based on one used final results EXO-200, produce sensitivity prediction that exceeds half-life 10 28 years. Specifically, improvements have been made understanding production scintillation photons charge as...
This study examines the causal relationships between economic growth and factor inputs, namely physical capital, labour, human research development in China's top six powerhouses, including Guangdong, Jiangsu, Shandong, Zhejiang, Henan Sichuan provinces with annual data over period from 1996 to 2022 Dumitrescu Hurlin (2012) Juodis et al. (2021) Granger non-causality tests. Both test suggest that there are R&D growth. Additionally, observed bidirectional causality, some instances, highlights...
University faculty, including female teachers, often face work-family conflict (WFC) which subsequently impacts their work engagement. This study analyzes data from 489 questionnaires using Mplus 8.0 to explore the internal mechanisms linking WFC and engagement among faculty. The uncovers several significant findings: (1) a negative correlation between teachers’ engagement; (2) job burnout mediates this relationship; (3) crafting grit both moderate relationship. These insights enrich human...
Unlike any other reference currently available, Computerized Adaptive and Multistage Testing with R: Using Packages catR mstR (Magis, Yan, & von Davier, 2017) deftly presents both the knowledge practice of adaptive testing seamlessly bridges gap between them. This phenomenal book is a rare achievement that serves as valuable for novices experts alike, such belongs on shelves anyone an interest in testing. At present, we know no introductory text uniquely poised to convert inert spectators...

Liquid xenon time projection chambers are promising detectors to search for neutrinoless double beta decay (0$\nu \beta \beta$), due their response uniformity, monolithic sensitive volume, scalability large target masses, and suitability extremely low background operations. The nEXO collaboration has designed a tonne-scale chamber that aims 0$\nu \beta$ of \ce{^{136}Xe} with projected half-life sensitivity $1.35\times 10^{28}$~yr. To reach this sensitivity, the design goal is $\leq$1\%...
Abstract The template‐based automated item‐generation (TAIG) approach that involves template creation, item generation, selection, field‐testing, and evaluation has more steps than the traditional development method. Consequentially, there is margin for error in this process, any errors can be cascaded to generated items. Therefore, it essential eliminate source of ensure quality so items problem‐free. article introduces a process reduce at early stage development, minimize impact on items,...

Generative Adversarial Networks trained on samples of simulated or actual events have been proposed as a way generating large datasets at reduced computational cost. In this work, novel approach to perform the simulation photodetector signals from time projection chamber EXO-200 experiment is demonstrated. The method based Wasserstein Network - deep learning technique allowing for implicit non-parametric estimation population distribution given set objects. Our network real calibration data...

With addition Phase II dataset taken an upgraded detector, median 90% confidence level half-life sensitivity 2 yr using total exposure 234.1 kg yr. No statistically...
Abstract Test items must often be broad in scope to ecologically valid. It is therefore almost inevitable that secondary dimensions are introduced into a test during development. A cognitive may require one or more abilities besides the primary ability correctly respond an item, which case unidimensional score overestimates and creates interpretability problems. In this article, we demonstrate nonproportional requirement, phenomenon with required for difficult items. novel practical method...
As a method to derive “purified” measure along dimension of interest from response data that are potentially multidimensional in nature, the projective item theory (PIRT) approach requires first fitting (MIRT) model before projecting onto interest. This study aims explore how accurate PIRT results when estimated MIRT is misspecified. Specifically, we focus on using (potentially misspecified) two-dimensional (2D)-MIRT for projection because its advantages, including interpretability,...
