Emergence and Growth of Complex Networks in Adaptive Systems [PDF]
, 1998 We consider the population dynamics of a set of species whose network of catalytic interactions is described by a directed graph. The relationship between the attractors of this dynamics and the underlying graph theoretic structures like cycles and ...

Population Dynamics and Non-Hermitian Localization
, 1999 We review localization with non-Hermitian time evolution as applied to simple models of population biology with spatially varying growth profiles and convection.

Adaptive dynamics in logistic branching populations [PDF]
, 2007 We consider a trait-structured population subject to mutation, birth and competition of logistic type, where the number of coexisting types may fluctuate.

Modeling Best Practice Life Expectancy Using Gumbel Autoregressive Models
Risks, 2021 Best practice life expectancy has recently been modeled using extreme value theory. In this paper we present the Gumbel autoregressive model of order one—Gumbel AR(1)—as an option for modeling best practice life expectancy. This class of model represents

Entropy production of cyclic population dynamics
, 2010 Entropy serves as a central observable in equilibrium thermodynamics. However, many biological and ecological systems operate far from thermal equilibrium. Here we show that entropy production can characterize the behavior of such nonequilibrium systems.

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

Myopic Models of Population Dynamics on Infinite Networks [PDF]
, 2013 Reaction-diffusion equations are treated on infinite networks using semigroup methods. To blend high fidelity local analysis with coarse remote modeling, initial data and solutions come from a uniformly closed algebra generated by functions which are ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

The impact of COVID-19 on life expectancy across socioeconomic groups in Denmark
Population Health MetricsBackground Denmark was one of the few countries that experienced an increase in life expectancy in 2020, and one of the few to see a decrease in 2021. Because COVID-19 mortality is associated with socioeconomic status (SES), we hypothesize that certain ...
