Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment

open access: yesFEBS Letters, EarlyView.
The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...

Hamilton-Souplet-Zhang’s Gradient Estimates for Two Types of Nonlinear Parabolic Equations under the Ricci Flow

open access: yesJournal of Function Spaces, 2016
We consider gradient estimates for two types of nonlinear parabolic equations under the Ricci flow: one is the equation ut=Δu+aulog⁡u+bu with a,b being two real constants; the other is ut=Δu+λuα with λ,α being two real constants.

Optimal continuous-path control for manipulators with redundant degrees of freedom [PDF]

open access: yesModeling, Identification and Control, 1989
A control system for macro-mini manipulators is presented. A position transformation from the end-effector reference to joint coordinates is found using kinematic optimization.

Optimal control theory of harmonic generation

open access: yes, 2012
Coherent control of harmonic generation was studied theoretically. A specific harmonic order was targeted. An optimal control theory was employed to find the driving field where restrictions were imposed on the frequency band.

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

open access: yesFEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

Optimal Control

open access: yes, 2004
Frequently, the engineer in charge of a process is faced with optimization problems. In fact, this may cover relatively different ideas, such as parameter identification or process optimization. It is known that the reactive feed flow rate profile for a fed-batch reactor and the temperature or pressure profile to be followed for a batch reactor, will ...

From lactation to malignancy: A comparison between healthy and cancerous breast gland at single‐cell resolution reveals new issues for tumorigenesis

open access: yesFEBS Letters, EarlyView.
Single‐cell RNA sequencing reveals an opposite role of SLPI in basal tumors based on metastatic spread, along with shared activation of specific regulons in cancer cells and mature luminal lactocytes, as well as downregulation of MALAT1 and NEAT1 in the latter.

Robustness Analysis of a Class of Optimal Control Systems [PDF]

open access: yesModeling, Identification and Control, 1983
This paper deals with a class of optimal control systems, where the controller. in addition to minimizing a quadratic criterion, also shall give the closed-loop system prescribed eigenvalues.
