Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Autonomous conversion of information to work in quantum dots

Physical Review Research, 2019
We consider an autonomous implementation of Maxwell's demon in a quantum dot architecture acting on a system without changing its number of particles or its energy. As in the original thought experiment, only the second law of thermodynamics is seemingly

Green function approach to mass fluctuation waves

, 1972
In earlier work, a model Hamiltonian has been used to study in detail the effects of 4He impurities in solid 3He. Starting with this Hamiltonian we use the Green function method, with a suitable decoupling scheme, to study the "mass fluctuation" waves ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Nanometer Scale Atomic Structure of Zirconium Based Bulk Metallic Glass

, 2011
We have studied the nanometer scale structure of bulk metallic glass (BMG) using fluctuation electron microscopy (FEM). The nanometer scale medium range order (MRO) in BMG is of significant interest because of its possible relationship to the properties,

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Model Predictive Control for Unmanned Excavator Based on Skilled Operator’s Operation Trajectory

IEEE Access
The operational trajectory of a skilled operator holds significant guiding implications for the motion control of unmanned excavators. This study collects and analyzes the operational trajectories of experienced operators under specific working ...

Introducing one-shot work into fluctuation relations [PDF]

, 2015
Two approaches to small-scale and quantum thermodynamics are fluctuation relations and one-shot statistical mechanics. Fluctuation relations (such as Crooks' theorem and Jarzynski's equality) relate nonequilibrium behaviors to equilibrium quantities such

Fluorescence fluctuation analysis of Arabidopsis thaliana somatic embryogenesis receptor-like kinase and brassinosteroid insensitive 1 receptor ologomerization.

, 2008
Receptor kinases play a key role in the cellular perception of signals. To verify models for receptor activation through dimerization, an experimental system is required to determine the precise oligomerization status of proteins within living cells ...
