Astrocyte heterogeneity in brain metastases

open access: yesMolecular Oncology, EarlyView.
Astrocytes emerge as pivotal regulators of metastatic colonization, survival, immune remodeling, and therapy response associated with an increasing heterogeneity that requires spatially and longitudinally resolved approaches to uncover regulatory programs and guide context‐specific therapies.

MODELING AND CONTROL OF FLEXIBLE STRUCTURES WITH WEAKNESSES [PDF]

open access: yes, 2010
The modeling and control of flexible structures with weaknesses is investigated. First a modular, computationally efficient, and numerically stable method is presented, which allows to obtain the dynamic model of a robot constituted by flexible links ...

DISCRETE-TIME ROBUST CONTROL FOR ROBOT-MANIPULATOR [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2013
The problem of robot-manipulator control is considered under uncertainty in robot dynamic parameters and input noise. The linear discrete-time regulator is proposed for desired motion stabilization of robot-manipulator.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

A new methodology for designing PD controllers [PDF]

open access: yes, 2001
It is known that it is impossible to select fixed gains for a PD controller that will critically damp the response to disturbances for all configurations of a given robot system. Because of this the potential for overshoot is always present and cannot be

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

open access: yesFEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

A nonlinear disturbance observer for robotic manipulators [PDF]

open access: yes, 2000
A new nonlinear disturbance observer (NDO) for robotic manipulators is derived in this paper. The global exponential stability of the proposed disturbance observer (DO) is guaranteed by selecting design parameters, which depend on the maximum velocity ...
