Three dimensionally mapping the relative spatial distributions and magnitudes of the various energy sources used in the MR imaging process for a given MR scanner potentiates an understanding of the relative spatial distributions of the potential risks associated with each of these energies or fields. By systematically analyzing the data for each energy source relative to the location and type of implants, devices, and/or foreign bodies within a specific patient, one can prospectively assess and even begin to quantify the risks of exposing that patient to selected MR scanner hardware for a requested diagnostic study.

Objective: To describe the mortality profile and analyze the spatiotemporal distribution of COVID-19 mortality among international migrants residing in Brazil from 2020 to 2022.
Methods: This is a descriptive and ecological cross-sectional study using secondary data. Absolute and relative frequencies of the sociodemographic profile and mortality coefficients (MCs) were analyzed.

Background: Lung adenocarcinoma is one of the most common malignant tumors worldwide. Its complex molecular mechanisms and high tumor heterogeneity pose significant challenges for clinical treatment. The manganese ion metabolism family plays a crucial role in various biological processes, and the abnormal expression of the NUDT3 gene in multiple cancers has drawn considerable attention.

Humans experience widespread exposure to anthropogenic per- and polyfluoroalkyl substances (PFAS) through various media, which can lead to a wide range of negative health impacts. Tap water is an important source of exposure in communities with any degree of contamination but routine or large-scale PFAS monitoring often depends on targeted analytical methods limited to measuring specific PFAS. We analyzed 680 tap water samples from the American Healthy Homes Survey II for PFAS using non-targeted analysis (NTA) to expand the range of detectable PFAS.

Background: Legacy dump sites pose health and environmental risks. Challenges such as difficulty in monitoring and the impact of policy changes towards remediation efforts remain enigmatic due to complexities.
Objectives: Hence this study aimed to use Geographic Information System (GIS) and Google Earth historical imagery to monitor changes in legacy dump site located at Sarona in Raipur and to assess the impact of waste management strategies being implemented currently.

When objects are grouped in space, humans can estimate numerosity more precisely than when they are randomly scattered. This phenomenon, called groupitizing, is thought to arise from the interplay of two components: the subitizing system which identifies both the number of subgroups and of items within each group, and the possibility to perform basic arithmetic operations on the subitized groups. Here we directly investigate the relative role of these two components in groupitizing via an interference (dual task) paradigm.
