Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

open access: yesFEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Finite-time impulsive consensus tracking control of nonlinear multi-agent systems

open access: yes, 2022
In this paper, the problems of finite-time consensus (FTC) tracking control for nonlinear multi-agent systems (MAS) with impulsive effects are discussed, in which the stabilizing and destabilizing impulses are considered, respectively.

Output Tracking Control for Networked Control Systems

open access: yesProceedings of the 13th International Conference on Informatics in Control, Automation and Robotics, 2016
This paper aims to compare alternative time delay relaxations for a class of nonlinear systems controlled via network and described by Takagi-Sugeno fuzzy models. In this regard, three alternatives were proposed and compared with a very recent relaxation proposed in the literature. Basically, the changes are made at two strategic points.

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Diagnostic effectiveness of HIV-1 quantitative nucleic acid assay as a supplementary test for individuals with indeterminate or negative western blot antibody test results — China, 2018–2023

open access: yesBMC Infectious Diseases
Background Based on China’s current HIV-1 testing algorithm, samples with initial positive antibody screening require two additional repeat tests, with infection status confirmed by HIV-1 antibody Western Blot or nucleic acid testing (NAT).

DTC: Deep Tracking Control

open access: yesScience Robotics
Legged locomotion is a complex control problem that requires both accuracy and robustness to cope with real-world challenges. Legged systems have traditionally been controlled using trajectory optimization with inverse dynamics. Such hierarchical model-based methods are appealing because of intuitive cost function tuning, accurate planning ...

Discerning protein pools by selective staining with self‐labeling tags

open access: yesFEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

Iterative learning control for multiple point-to-point tracking application [PDF]

open access: yes, 2011
A framework is developed which enables a general class of linear Iterative Learning Control (ILC) algorithms to be applied to tracking tasks which require the plant output to reach given points at predetermined time instants, without the need for ...
