Article Abstract
Bullying is a significant issue in schools, leading to various negative outcomes. The Elos 2.0 Program, a Brazilian adaptation of the Good Behavior Game, aims to reduce such behaviors through structured activities among elementary school students. A randomized controlled trial was conducted with 2,267 first to fourth-grade students from 11 public elementary schools in the Northeast region of Brazil. Using a modified version of the Revised Olweus Bully/Victim Questionnaire, we compared 1,112 children who were submitted to Elos 2.0 intervention with 1,155 participants who were in the control group. Our analysis showed no significant difference in bullying post-intervention. Multilevel logistic regression, adjusted for age and grade, presented no significant effects of the intervention on type I improvement ( = .548) or type II improvement ( = .633). Improvement type I includes maintaining a noninvolvement status in bullying, while improvement type II focuses strictly on those who stopped being involved in bullying. The Elos 2.0 Program did not significantly reduce bullying among students. Further research is needed to explore alternative strategies or program modifications to existing programs to effectively address bullying in school settings.

Statement Of Problem: Artificial intelligence (AI)-based applications have been integrated into intraoral scanner (IOS) programs aiming to assist the digitizing procedure, including the automatic alignment of the computer-aided design (CAD) file of the selected implant scan body (ISB). However, the impact of this AI-based application on the accuracy of complete arch implant scans remains unknown.
Purpose: The purpose of this in vitro study was to assess the impact of an AI-based application on the accuracy of complete arch implant scans recorded by using an IOS.

CXCL13 is a chemokine that plays an important role in the regulation and development of secondary lymphoid organs. CXCL13 is also involved in the regulation of pathological processes, particularly inflammatory responses, of many diseases. The function of CXCL13 varies depending on the condition of the host.

Background: The COVID-19 pandemic has affected the outcomes and access to elective surgery across the United States. This study hypothesized that preexisting racial and ethnic disparities were exacerbated by the pandemic for bariatric surgery.
Methods: This retrospective cohort study evaluated the outcome disparities in 1,046,578 patients who underwent bariatric surgery from 2016-2019 (before the COVID-19 pandemic) to 2020-2021 (during the COVID-19 pandemic) using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database.
An Improved ELOS Guidance Law for Path Following of Underactuated Unmanned Surface Vehicles.

In this paper, targeting the problem that it is difficult to deal with the time-varying sideslip angle of an underactuated unmanned surface vehicle (USV), a line-of-sight (LOS) guidance law based on an improved extended state observer (ESO) is proposed. A reduced-order ESO is introduced into the identification of the sideslip angle caused by the environmental disturbance, which ensures a fast and accurate estimation of the sideslip angle. This enables the USV to follow the reference path with high precision, despite external disturbances from wind, waves, and currents.
