Tropical forest succession increases tree taxonomic and functional richness but decreases evenness

Global Ecology and Biogeography, Volume 33, Issue 8, August 2024.
Abstract Aim Successional changes in functional diversity provide insights into community assembly by indicating how species are filtered into local communities based on their traits. Here, we assess successional changes in taxonomic and functional richness, evenness and redundancy along gradients of climate, soil pH and forest cover.

Creating a safer and better functioning system: Lessons to be learned from the Netherlands for an ethical defence of an autonomy‐only approach to assisted dying

Bioethics, Volume 38, Issue 6, Page 558-565, July 2024.
Abstract The proposal to allow assisted dying for people who are not severely ill reignited the Dutch end‐of‐life debate when it was submitted in 2016. A key criticism of this proposal is that it is too radical a departure from the safe and well‐functioning system the Netherlands already has. The goal of this article is to respond to this criticism and

GPU peer-to-peer techniques applied to a cluster interconnect

, 2013
Modern GPUs support special protocols to exchange data directly across the PCI Express bus. While these protocols could be used to reduce GPU data transmission times, basically by avoiding staging to host memory, they require specific hardware features ...

Artificial Cells and HepG2 Cells in 3D‐Bioprinted Arrangements

Advanced Healthcare Materials, Volume 13, Issue 12, May 7, 2024.
HepG2 cell aggregates are printed together with artificial cells with CYP1A2‐like activity as part of the composite ink with an alginate/gelatin methacryloyl liquid phase. The HepG2 cells proliferate over at least 35 days embedding the artificial cells. The resulting semi‐synthetic tissue shows a boosted conversion of resorufin ethyl ether to resorufin
