Linking differences in personality to demography in the wandering albatross

open access: yesOikos, EarlyView.
Population dynamics are shaped by individual differences. With a good understanding of the relationships between individual differences and vital rates, population models can be improved to yield more realistic and detailed demographic projections. Personality is expected to shape individual differences in performance.

Realpolitik and multistate system stability [PDF]

open access: yes, 2011
This paper describes a project focused on the theoretical value of realism to the study of international relations. A large number of the primary assumptions and propositions within realism are detailed and evaluated in light of results drawn from ...

Modeling of Disease Progression of Type 2 Diabetes Using Real‐World Data: Quantifying Competing Risks of Morbidity and Mortality

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 606-615, March 2025.
ABSTRACT Type 2 diabetes (T2D) is a progressive metabolic disorder that could be an underlying cause of long‐term complications that increase mortality. The assessment of the probability of such events could be essential for mortality risk management. This work aimed to establish a framework for risk predictions of macrovascular complications (MVC) and

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

open access: yesPackaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

Parameter Interval Estimation of System Reliability for Repairable Multistate Series-Parallel System with Fuzzy Data

open access: yesThe Scientific World Journal, 2014
The purpose of this paper is to create an interval estimation of the fuzzy system reliability for the repairable multistate series–parallel system (RMSS). Two-sided fuzzy confidence interval for the fuzzy system reliability is constructed.

Optimal planning of stand-alone microgrids incorporating reliability

open access: yesJournal of Modern Power Systems and Clean Energy, 2014
This paper proposes a new method for the planning of stand-alone microgrids. By means of clustering techniques, possible operating scenarios are obtained considering the daily patterns of wind and load profiles.

Population Dynamics of Northern Pearl Dace Margariscus nachtriebi in Anthropogenically Altered Headwater Streams of the Nebraska Sandhills Ecoregion

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Empirical evidence of population demographic responses to environmental perturbations is a major knowledge gap for aquatic vertebrate populations. Extensive habitat alteration including channelization of headwater streams influences the habitat template on which small‐bodied fish are dependent to carry out distinct life stages and maintain or ...

Dynamical order and many-body correlations in zebrafish show that three is a crowd

open access: yesNature Communications
Zebrafish constitute a convenient laboratory–based biological system for studying collective behavior. It is possible to interpret a group of zebrafish as a system of interacting agents and to apply methods developed for the analysis of systems of active
