Modeling marine surface microplastic transport to assess optimal removal locations

Environmental Research Letters, 2016
Marine plastic pollution is an ever-increasing problem that demands immediate mitigation and reduction plans. Here, a model based on satellite-tracked buoy observations and scaled to a large data set of observations on microplastic from surface trawls ...

Optimal Design of Bus Stop Locations Integrating Continuum Approximation and Discrete Models

Journal of Advanced Transportation, 2020
Although transit stop location problem has been extensively studied, the two main categories of modeling methodologies, i.e., discrete models and continuum approximation (CA) ones, seem have little intersection.

Dynamic Repositioning of Aerial Base Stations for Enhanced User Experience in 5G and Beyond

Sensors, 2023
The ultra-dense deployment (UDD) of small cells in 5G and beyond to enhance capacity and data rate is promising, but since user densities continually change, the static deployment of small cells can lead to wastes of capital, the underutilization of ...

Optimal Jammer Placement in Wireless Localization Systems [PDF]

, 2016
In this study, the optimal jammer placement problem is proposed and analyzed for wireless localization systems. In particular, the optimal location of a jammer node is obtained by maximizing the minimum of the Cramer-Rao lower bounds (CRLBs) for a number

Lifestyle Behaviors and Cardiotoxic Treatment Risks in Adult Childhood Cancer Survivors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Higher doses of anthracyclines and heart‐relevant radiotherapy increase cardiovascular disease (CVD) risk. This study assessed CVD and CVD risk factors among adult childhood cancer survivors (CCSs) across cardiotoxic treatment risk groups and examined associations between lifestyle behaviors and treatment risks.

Monopolistic Location Choice in Two-Sided Industries [PDF]

, 2012
We analyze the optimal location choice of a monopolistic firm that operates two platforms on a two-sided market. We show that the optimal platform locations are equivalent to the one-sided benchmark if both sides are either restricted to single- or multi-

Parent‐to‐Child Information Disclosure in Pediatric Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...

Predicting Chronicity in Children and Adolescents With Newly Diagnosed Immune Thrombocytopenia at the Timepoint of Diagnosis Using Machine Learning‐Based Approaches

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...

Determining Optimal Surveillance Camera Installation Locations for Crime Prevention

IEEE Access
The strategic deployment of surveillance cameras plays a crucial role in enhancing urban safety by reducing crime. However, unsystematic installation criteria often create surveillance overlaps and blind spots. This study addresses this issue by applying
