Examining Children’S Intuitive Understanding Of Mechanical Systems With A Gears Assembly Task, Nicole Taboada

Theses

Children’s causal reasoning about machines and their components is crucial for acquiring knowledge about science and math. Mechanistic understanding involves knowing how parts can be effectively connected to work together as a functional mechanical system. Little is known about how children’s understanding of mechanical systems develops across the lifespan. Legare and Lombrozo (2014) developed a gears assembly task to assess children’s understanding and learning of mechanics but did not track this skill across ages. The present study adapted the gears assembly task to measure mechanistic understanding in children between the ages of 4 to 11 years and adults. The goal …

Multisource Information Fusion Method For Human Gait Perception, Guiliang Chen, Guowei Liu, Yongchao Li, Chao Cai, Zihao Li, Dong Yang

Journal of System Simulation

Abstract: In response to the insufficient gait perception capability during lower limb exoskeleton assistance, a human lower limb gait phase optimization classification model was proposed. A wireless transmission gait information collection system was designed for collecting the required gait phase feature information. Human joint angles were accurately calculated by fusing acceleration and angular velocity information using extended Kalman filtering. Additionally, kernel principal component analysis was applied to reduce dimensionality in conjunction with plantar pressure data. The LSSVM algorithm was employed to classify gait data, and the PSO algorithm was utilized to find the optimal classification parameters. Experimental results demonstrate that …

Clinical Course And Treatment Outcomes In Solid-Basaloid Adenoid Cystic Carcinoma Of The Breast: A Systematic Review And Case Report, Stephanie Kim, Kyle Sheth, Xiaoying Yu, Laura Porterfield, Elizabeth M Vaughan

Faculty, Staff and Students Publications

Background: Adenoid Cystic Carcinoma (ACC) is a rare, indolent subtype of triple-negative breast cancer, accounting for < 0.1 % of cases. The solid-basaloid subtype (SBACC), comprising approximately one-quarter of breast ACCs, has a poorer prognosis. While ACC is typically managed with surgery and is chemo-resistant, SBACC is more aggressive and often treated with chemotherapy and, more recently, immunotherapy-though supporting evidence remains limited.

Aim: To assess clinical characteristics and treatment outcomes of SBACC of the breast.

Methods: This study presents a case of breast SBACC and a systematic review of five databases (inception-September 10, 2024). Eligible studies reported clinical course, treatment, and outcomes. Exclusions included duplicates, non-SBACC focus, animal studies, and those lacking clinical or with only pathological data. Descriptive statistics were used for binary and categorical variables. Risk of bias was assessed using JBI tools, following PRISMA 2020 guidelines. The review is registered in PROSPERO.
