Mathematical Circuit Root Simplification Using an Ensemble Heuristic–Metaheuristic Algorithm

open access: yesMathematics, 2023
Symbolic pole/zero analysis is a crucial step in designing an analog operational amplifier. Generally, a simplified symbolic analysis of analog circuits suffers from NP-hardness, i.e., an exponential growth of the number of symbolic terms of the transfer

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Exploiting Vestibular Output during Learning Results in Naturally Curved Reaching Trajectories [PDF]

open access: yes, 2005
Teaching a humanoid robot to reach for a visual target is a complex problem in part because of the high dimensionality of the control space. In this paper, we demonstrate a biologically plausible simplification of the reaching process that replaces the ...

Super M-brane actions in adS_4 x S^7 and adS_7 x S^4

open access: yes, 1998
The world-volume action of the M2 brane and the M5-brane in an adS_4 x S^7 and a adS_7 x S^4 background is derived to all orders in anticommuting superspace coordinates.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Pour une simplification de la terminologie médicale multilingue : le cas du projet ExaMode

open access: yesMediAzioni
Several studies have highlighted the complexity of medical language, which can prevent non-experts from understanding it, and the need to overcome this problem by developing a simplified variety of this language.

Vlad Mugur şi „teatrul mare” [PDF]

open access: yesStudii si Cercetari de Istoria Artei : Teatru, Muzică, Cinematografie, 2017
En juin 2000, peu après que Ion Vartic avait pris la direction du Théâtre National de Cluj, j’ai été invitée dans son bureau pour prendre part à une brève entrevue avec Vlad Mugur.
