FTF: a quick surveying approach for constructing high resolution digital surface model for road elements

open access: yesGeomatics, Natural Hazards & Risk, 2020
Digital Surface Models (DSMs) are commonly built using data collected via remote sensing techniques such as aerial photogrammetry, LiDAR, and InSAR. DSM accuracy mainly depends upon the type of data used beside the methodology followed.

Giving and receiving help in three contexts as predictors of alcohol outcomes in a longitudinal study of sober living house residents

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Although peer support is central to the social model approach emphasized in sober living houses (SLHs), no longitudinal studies have examined helping among SLH residents. This longitudinal study examined benefits of helping in three contexts among SLH residents. Data were from 205 participants entering 28 SLHs across 2021–2023. Interviews were

Are There Causal Associations Between Obsessive‐Compulsive Disorder and Cardiometabolic Phenotypes? A Genetic Correlation and Bi‐Directional Mendelian Randomization Study

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT In epidemiological studies, obsessive‐compulsive disorder (OCD) is robustly associated with increased risk of cardiometabolic disorders, including cardiovascular diseases, type 2 diabetes, and obesity. However, the mechanisms behind these associations are unclear. We conducted genetic correlation analyses to explore shared genetic etiology and
