Heart rate and oxygen uptake kinetics obtained from continuous measurements with wearable devices during outdoor walks of patients with COPD

Digital Health, 2023
Objective Continuous physiological measurements during a laboratory-based exercise test can provide physiological biomarkers, such as heart rate (HR) and oxygen uptake (V̇O 2 ) kinetics, that carry clinically relevant information.

Model Risk in Portfolio Optimization

Risks, 2014
We consider a one-period portfolio optimization problem under model uncertainty. For this purpose, we introduce a measure of model risk. We derive analytical results for this measure of model risk in the mean-variance problem assuming we have ...

Global EarthquakE ScEnarios (GEESE): An OpenQuake Engine-Based Rupture Matching Algorithm and Scenarios Database for Seismic Source Model Testing and Rapid Post-Event Response Analysis

Seismica
The Global EarthquakE ScEnarios (GEESE) algorithm retrieves from a seismic hazard input model the ruptures matching a set of criteria (e.g., magnitude, location, focal mechanism).

An examination of process models and model risk frameworks for pharmaceutical manufacturing

International Journal of Pharmaceutics: X
Process models are a growing tool for pharmaceutical manufacturing process design and control. The Industry 4.0 paradigm promises to increase the amount of data available to understand manufacturing processes.

The LLP risk model: an individual risk prediction model for lung cancer [PDF]

British Journal of Cancer, 2007
Using a model-based approach, we estimated the probability that an individual, with a specified combination of risk factors, would develop lung cancer within a 5-year period. Data from 579 lung cancer cases and 1157 age- and sex-matched population-based controls were available for this analysis.

Modelling Bluetongue Risk in Kazakhstan [PDF]

Parasites & Vectors, 2020
Abstract Background: Bluetongue is a serious disease of ruminants transmitted by biting midges (Culicoides spp). Serological evidence from livestock and the presence of at least one vector competent spp of Culicoides suggests that transmission of bluetongue is possible and may have occurred in Kazakhstan. Methods: We estimated the relative risk

Modeling and Optimization of Risk

Surveys in Operations Research and Management Science, 2011
Abstract This paper surveys the most recent advances in the context of decision making under uncertainty, with an emphasis on the modeling of risk-averse preferences using the apparatus of axiomatically defined risk functionals, such as coherent measures of risk and deviation measures, and their connection to utility theory, stochastic dominance, and

Information-Theoretic Analysis of Bayesian Quantum State Search

IEEE Transactions on Quantum Engineering
We present an information-theoretic approach to quantum state classification based on sequential Bayesian inference. In each measurement step, the algorithm updates a probability distribution over candidate states by applying Bayes' rule to the ...

Daily allergy burden and heart rate characteristics in adults with allergic rhinitis based on a wearable telemonitoring system

Clinical and Translational Allergy, 2023
Background Allergic rhinitis includes a certain degree of autonomic imbalance. However, no information is available on how daily changes in allergy burden affect autonomic imbalance. We aimed to estimate associations between daily allergy burden (allergy
