The Rayleigh–Taylor instability of two-dimensional high-density vortices [PDF]

open access: yes, 2005
We investigate the stability of variable-density two-dimensional isolated vortices in the frame of incompressible mixing under negligible gravity. The focus on a single vortex flow stands as a first step towards vortex interactions and turbulent mixing ...

A dislocation-based model for the substructure evolution and flow stress of aluminum alloys during high-temperature compression

open access: yesJournal of Materials Research and Technology
The microstructure evolution of aluminum alloys during plastic deformation is a complex metallurgical process controlled by interacting physical mechanisms, such as recovery, continuous dynamic recrystallization (CDRX), and substructure evolution.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Density (dis)economies in transportation: revisiting the core-periphery model [PDF]

open access: yes
We study how density (dis)economies in interregional transportation influence location patterns in a standard new economic geography model. Density economies may well delay the occurrence of agglomeration when compared to the case without such economies,

The constant philopater hypothesis : a new life history invariant for dispersal evolution [PDF]

open access: yes, 2015
This research was supported by Wolfson College Cambridge (A.M.M.R.) and the Natural Environment Research Council (grant no. NE/K009524/1) (A.G.).Surprising invariance relationships have emerged from the study of social interaction, whereby a cancelling ...

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

open access: yesFEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Nonparametric confidence bands in deconvolution density estimation [PDF]

open access: yes
Uniform confidence bands for densities f via nonparametric kernel estimates were first constructed by Bickel and Rosenblatt [Ann. Statist. 1, 1071.1095].
