Control Sets and Total Positivity
Semigroup Forum, 2004 The goal of this paper is to connect two different mathematical subjects, namely totally positive matrices and control sets. The set \(T\) of totally positive matrices in \(Sl(d,\mathbb{R})\) (subgroup of determinant one matrices of size \(d \times d\)) is also a semigroup with non-empty interior in \(Sl(d,\mathbb{R})\).

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

The control of the arm’s equilibrium position
Journal of NeurophysiologyAccording to numerous theories, the brain controls posture and movement by activating muscles that attract the limb toward a so-called equilibrium position, but the universality of this mechanism has not been shown for different motor behaviors. Here, we show that even when pushing or pulling against the environment, the brain achieves the desired ...

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.

Rendez-Vous and Docking Position Tracking via Sliding Mode Control
, 2015 This paper proposes a sliding mode strategy for the Chaser position tracking during the approaching maneuver to a passive vehicle (Target). The presented sliding mode control procedure considers different phases of the approaching maneuver, which are ...

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.

Impedance control of a hydraulically actuated robotic excavator
, 2000 In robotic excavation, hybrid position/force control has been proposed for bucket digging trajectory following. In hybrid position/force control, the control mode is required to switch between position- and force-control depending on whether the bucket ...
