FEBS Letters, EarlyView.Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Continuous Time Matrix Programming
Journal of Mathematical Analysis and Applications, 1993 Duality and saddlepoint conditions are considered for the following pair of problems: \[ \max\int^ T_ 0 A(t)X(t)dt\qquad\text{subject to}\tag{P} \] \[ B(t)X(t)\leq C(t)+\int^ t_ 0 K(t,s)X(t)ds\quad\text{a.e. in }[0,T],\quad X(t)\geq 0\quad\text{a.e.

Continuous-time mean-variance portfolios: a comparison
, 2013 In this article, we present and compare three mean-variance optimal portfolio approaches in a continuous-time market setting. These methods are the L-2-projection as presented in Schweizer [M.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Continuous-Time Multivariate Analysis
Journal of Computational and Graphical StatisticsThe starting point for much of multivariate analysis (MVA) is an n × p data matrix whose n rows represent observations and whose p columns represent variables. Some multivariate datasets, however, may be best conceptualized not as n discrete p-variate observations, but as p curves or functions defined on a common time interval.

A Survey on Continuous Time Computations [PDF]
, 2008 We provide an overview of theories of continuous time computation. These theories allow us to understand both the hardness of questions related to continuous time dynamical systems and the computational power of continuous time analog models. We survey the existing models, summarizing results, and point to relevant references in the literature.

Generalized continuous-time random walks, subordination by hitting times, and fractional dynamics [PDF]
, 2009 Functional limit theorems for continuous-time random walks (CTRW) are found in the general case of dependent waiting times and jump sizes that are also position dependent.
