Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Vaccine, 2015 For many decades the only adjuvants accepted in human licensed vaccines have been particulate substances such as alum and emulsions. These compounds have been identified empirically, based on their ability to enhance immune responses to vaccination in animals, without understanding their mechanism of action.

Dendritic cells steering antigen and leukocyte traffic in lymph nodes
FEBS Letters, EarlyView.Dendritic cells are key players in the activation of T cells and their commitment to effector function. In this In a Nutshell Review, we will discuss how dendritic cells guide the trafficking of antigen and leukocytes in the lymph node, thus influencing T‐cell activation processes. Dendritic cells (DCs) play a central role in initiating and shaping the

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

FEBS Letters, EarlyView.UDP‐glucuronic acid 4‐epimerase (UGAepi) catalyzes NAD+‐dependent interconversion of UDP‐glucuronic acid (UDP‐GlcA) and UDP‐galacturonic acid (UDP‐GalA) via C4‐oxidation, 4‐keto‐intermediate rotation, and C4‐reduction. Here, Borg et al. examined the role of the substrate's carboxylate group in the enzymic mechanism by analyzing NADH‐dependent reduction

Current and cumulative malaria infections in a setting embarking on elimination: Amhara, Ethiopia
Malaria Journal, 2017 Background Since 2005, Ethiopia has aggressively scaled up malaria prevention and case management. As a result, the number of malaria cases and deaths has significantly declined.

Increasing Returns and Path Dependence in the Economy
, 1994 When the University of Michigan Press approached me to bring out a book of collected papers on increasing returns in economics I was surprised. I had thought that only older researchers, venerable and near retirement, issued collected works.

E-rea, 2007 I am grateful to Ray DiPalma for his generously giving me access to copies of An August Daybook (2005), Mules at the Wake (2006) and Ascoso (2006). All other quotes from DiPalma are from a private correspondence. There is a delicate balance in iDEATH. It suits us.(Richard Brautigan In Watermelon Sugar) An autobiography is about an “I” and it traces a ...

Pathwise vs. path-by-path uniqueness
Annales de l'Institut Henri Poincaré, Probabilités et Statistiques, 2022 We construct a series of stochastic differential equations of the form $dX_t = b(t, X_t) dt + dB_t$ which exhibit nonuniqueness in the path-by-path sense while having a unique adapted solution in the sense of stochastic processes, i.e. pathwise uniqueness holds.
