Minimum energy configurations of the 2-dimensional HP-model of proteins by self-organizing networks [PDF]

open access: yes, 2002
We use self-organizing maps (SOM) as an efficient tool to find the minimum energy configurations of the 2-dimensional HP-models of proteins. The usage of the SOM for the protein folding problem is similar to that for the Traveling Salesman Problem.

Selective suppression of melanoma lacking IFN-γ pathway by JAK inhibition depends on T cells and host TNF signaling

open access: yesNature Communications, 2022
Tumor loss of IFN-γ signalling is a major mechanism of resistance to immune checkpoint blockers. Here the authors report that melanoma cells with knockout of IFNγR1 show constitutive JAK1/2 activation and that the JAK1/2 inhibitor ruxolitinib can ...

Optogenetic assessment of VIP, PV, SOM and NOS inhibitory neuron activity and cerebral blood flow regulation in mouse somato-sensory cortex

open access: yesJournal of Cerebral Blood Flow and Metabolism, 2019
The impact of different neuronal populations on local cerebral blood flow (CBF) regulation is not well known and insight into these relationships could enhance the interpretation of brain function and dysfunction from brain imaging data.

Living roots magnify the response of soil organic carbon decomposition to temperature in temperate grassland

open access: yesGlobal Change Biology, Volume 21, Issue 3, Page 1368-1375, March 2015., 2015
Abstract Increasing atmospheric carbon dioxide (CO2) concentration is both a strong driver of primary productivity and widely believed to be the principal cause of recent increases in global temperature. Soils are the largest store of the world's terrestrial C. Consequently, many investigations have attempted to mechanistically understand how microbial
