Summary: This study evaluated the influence of formalin fixation time on the elemental composition of human tissue samples using EDXRF. The results showed a clear decrease of Cl and K in the tissues during formalin fixation, and an uptake of P, likely due to the buffered formalin solution. These findings suggest that there may be different thresholds for the use of these elements as diagnostic tools in unfixed and formalin-fixed paraffin embedded tissues.

Summary: Through X-ray fluorescence analysis of 69 ancient Numidian coins, it was discovered that coins from the kingdom of Massinissa were lead-rich, while coins from other kingdoms used copper-based alloys. The results revealed three distinct groups of coins, reflecting consistency with technological and historical evolution.

Summary: To improve the performance of DNA sequencing results, researchers used replicates and various statistical clustering models. Comparison of five model types revealed that the Kamila model showed the best overall performance with high precision and sensitivity. Non-supervised clustering models, such as the Gaussian mixture model and Kamila, offered notable precision and F1-score improvements over supervised models. These models can be recommended for callset reconstruction in diagnostic or precision medicine.

Summary: This article investigates real-time levitation performance optimization of the EML system with an imperfectly known model. The system is first modeled and an equivalent demonstration benchmark is developed. Then, a structure for levitation performance optimization is presented on top of the coprime factorization technique. Furthermore, a real-time levitation performance optimization algorithm is developed, utilizing only the input and output data.

Summary: Despite the increasing levels of customer aggression in the retail and services sector, there is currently no comprehensive tool to measure such behavior, which hinders empirical examinations. This research conducted five studies, including a student survey, an expert panel review, and three retail worker surveys. The results identified a 19-item Customer Aggression scale with four factors. The scale was shown to have nomological validity by demonstrating its impact on employee emotional exhaustion, job stress, organizational deviance, and intention to leave. This research contributes a parsimonious, reliable, and valid scale to measure customer aggression, facilitating further scientific inquiry.

Summary: In this paper, a portmanteau test is proposed to examine the autocorrelation in a graph-structured network dataset without replicates. The Ljung-Box test is generalized to the network setting using a central limit theorem, and the asymptotic distribution of the test statistic is derived. Numerical simulations demonstrate the validity of the proposed method, showing fast convergence and increased statistical power compared to permutation tests. An application example fitting spatial autoregressive models to COVID-19 cases in New York state is presented.

Summary: This study developed and validated the Extremist Archetypes Scale, identifying five distinct archetype dimensions, and found that these dimensions were related to violent intentions. The dimensions differed in terms of sociopolitical ideologies and intergroup attitudes, as well as personality traits. Measurement equivalence was established across different groups.

Summary: Green growth is crucial for developing countries, with Morocco prioritizing it along with sustainable energy practices. The study found that Morocco's comprehensive evaluation index of green growth has been increasing over the years, but the growing resource investment and economic benefit indices are accompanied by increasing environmental impacts.

Summary: Time use data is important in analyzing labor supply, especially for women engaged in unpaid care and home production. Assisted diary-based surveys are expensive and not widely used, thus a low-cost, scalable alternative is needed. We have created a module that captures broad time categories like market work, household labor, and leisure, with fewer categories and longer intervals, saving 33% of the time compared to traditional modules. Field experiments show that this module effectively measures average time across broader categories, particularly for women. It is a viable method for household and labor force surveys to track work and leisure patterns as economies develop.

Summary: Time-bin qudits are a promising encoding platform in quantum photonic applications. However, the requirement for efficient single-shot measurement has limited their use in experiments. We propose a method to measure arbitrary superposition states of time-bin qudits using ultrafast time bins, enabling measurement in different bases.

Summary: This study collected PM10 samples from different periods between 2018 and 2020 and found a decrease in PM10 concentration, as well as changes in concentrations of certain elements and ions. Modeling analysis revealed the contributions of different pollution sources. The characteristics of PM10 were significantly influenced by the implementation of a ban and the COVID-19 pandemic.
