Vision in-experience : investigating the interaction between the correct non-prototypical colours of colour diagnostic objects and object representation in human observers [PDF]

, 2015
Hering (1964) hypothesized that the representation of a familiar object, which primarily includes its prototypical colour on the visual, conceptual and lexical domains may significantly influence how human observers organize the object’s chromatic ...

Functional Interval Observers-Based Active Fault Tolerant Control for Continuous-Time Linear Parameter-Varying Systems

IEEE Access
This article addresses the problem of Functional Interval Observers (FIO) based on Active Fault Tolerant Control for continuous-time polytopic Linear Parameter-Varying systems in the presence of unknown but bounded uncertainties, external disturbances ...

The power of tears: Observers’ brain responses show that tears provide unambiguous signals independent of scene context

NeuroImage: Reports, 2022
Only humans produce emotional tears, a fact that has been linked to triggering empathy, social bonding, and providing support in observers. Consequently, either the tears themselves play a crucial role in eliciting such behavior, or, alternatively, the ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

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.

Chaos-based communication scheme using proportional and proportional-integral observers [PDF]

, 2008
In this paper, we propose a new chaos-based communication scheme using the observers. The novelty lies in the masking procedure that is employed to hide the confidential information using the chaotic oscillator.

On the existence of strong functional observer

CoRR
For arbitrary linear time-invariant systems, the existence of a strong functional observer is investigated. Such observer determines, from the available measurement on the plant, an estimate of a function of the state and the input. This estimate converges irrespective to initial state and input.

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.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Sliding Mode Functional Observers for Nonlinear Systems

, 2008
This paper addresses the problem of estimating a linear function of the states of a nonlinear system using sliding mode functional observer approach. Sliding mode functional observers proposed in this paper are of low-order.
