Stressful Events Reported by Childhood Cancer Survivors and Community Controls From the St. Jude Lifetime (SJLIFE) Cohort: A Mixed Method Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.

Behavior of Copper, Nickel, Cadmium and Mercury Ions in Anode Chamber of Microbial Fuel Cells

International Journal of Electrochemical Science, 2018
Microbial fuel cell (MFC) technology is widely used in wastewater treatment, and heavy metal ions play a important role in MFCs. In this paper, we studied the effect of heavy metal ions (copper, nickel, cadmium and mercury) on anode, mainly in voltage ...

Effect of climate change and urbanisation on flood protection decision‐making

Journal of Flood Risk Management, 2021
The changing climate and the rapid urbanisation may alter flood severity and influence the decision‐making process for flood management. In this study, a Multi‐Criteria Decision Analysis (MCDA) framework for optimal decision‐making in flood protection is

Risk-Sensitive Markov Control Processes [PDF]

SIAM Journal on Control and Optimization, 2013
We introduce a general framework for measuring risk in the context of Markov control processes with risk maps on general Borel spaces that generalize known concepts of risk measures in mathematical finance, operations research and behavioral economics. Within the framework, applying weighted norm spaces to incorporate also unbounded costs, we study two

Asymptotic Distributions of the Overshoot and Undershoots for the L\'evy Insurance Risk Process in the Cram\'er and Convolution Equivalent Cases [PDF]

, 2011
Recent models of the insurance risk process use a L\'evy process to generalise the traditional Cram\'er-Lundberg compound Poisson model. This paper is concerned with the behaviour of the distributions of the overshoot and undershoots of a high level, for
