Adoption of projected mortality table for the Slovenian market using the Poisson log-bilinear model to test the minimum standard for valuing life annuities [PDF]

Economic and Business Review, 2015
With the introduction of Solvency II a consistent market approach to the valuation of insurance assets and liabilities is required. For the best estimate of life annuity provisions one should estimate the longevity risk of the insured population in ...

Contrasting Population Trends at Two Razorbill Colonies in Atlantic Canada: Additive Effects of Fox Predation and Hunting Mortality?

Avian Conservation and Ecology, 2009
We developed a stochastic, stage-based, matrix-projection population model to assess population viability and estimate the impact of mortality caused by hunting, illegal and incidental to the murre (Uria sp.) hunt, and fox (Alopex lagopus) predation on ...

Two Central Nervous System Tumors in One Catheter Lab: Time to Rethink Radiation Protection

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Very little research has been done on the possible effects that repeated, frequent, and low‐dose ionizing radiation exposure has on the long‐term health of interventional cardiologists. Aims Following the diagnosis in the same year of two central nervous system tumors in two operators working in the same catheter laboratory, we ...

GastroNet: A robust attention‐based deep learning and cosine similarity feature selection framework for gastrointestinal disease classification from endoscopic images

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Diseases of the Gastrointestinal (GI) tract significantly affect the quality of human life and have a high fatality rate. Accurate diagnosis of GI diseases plays a pivotal role in healthcare systems. However, processing large amounts of medical image data can be challenging for radiologists and other medical professionals, increasing the risk ...

TreeMig framework ver. 1.0: an R package with GUI to simulate spatio‐temporal forest dynamics

Ecography, EarlyView.
Spatio‐temporal vegetation models are essential for simulating dynamics and shifts in species distributions over large areas, particularly under global change. One such model is the dynamic forest landscape model TreeMig. We have developed a framework that makes the model more user‐friendly, improves its functionality, and expands its possibilities ...

Fully automated three‐dimensional deep learning‐based magnetic resonance imaging segmentation of brain cavities in epilepsy surgery

Epilepsia, EarlyView.
Abstract Objective There are several clinical and research applications for determining the amount of brain tissue resected after epilepsy surgery; however, manual segmentation of postoperative magnetic resonance imaging (MRI) is imprecise and time‐consuming.

Stochastic Compartment Model with Mortality and Its Application to Epidemic Spreading in Complex Networks

Entropy
We study epidemic spreading in complex networks by a multiple random walker approach. Each walker performs an independent simple Markovian random walk on a complex undirected (ergodic) random graph where we focus on the Barabási–Albert (BA), Erdös–Rényi (

Longevity Risk Management and the Development of a Value-Based Longevity Index

Risks, 2018
The design and development of post-retirement income products require the assessment of longevity risk, as well as a basis for hedging these risks. Most indices for longevity risk are age-period based. We develop and assess a cohort-based value index for

Flexible wearable electronics for cardiovascular monitoring from surface signals to deep physiological insights

FlexMat, EarlyView.
This review organizes flexible wearable electronics for cardiovascular monitoring into four interconnected information layers: surface electrophysiology, hemodynamic sensing, vascular imaging, and biofluid biomarker analysis. This framework clarifies how electrical rhythm, vascular loading, structural and flow‐related features, and biochemical states ...
