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.

Automated FRAP microscopy for high‐throughput analysis of protein dynamics in chromatin organization and transcription

open access: yesFEBS Open Bio, EarlyView.
RoboMic is an automated confocal microscopy pipeline for high‐throughput functional imaging in living cells. Demonstrated with fluorescence recovery after photobleaching (FRAP), it integrates AI‐driven nuclear segmentation, ROI selection, bleaching, and analysis.

Systematic Enumeration of Parallel Manipulators [PDF]

open access: yes, 1998
In this paper, a systematic methodology for enumeration of the kinematicstructures of parallel manipulators is presented. Parallel manipulators areclassified into planar, spherical, and spatial mechanisms.

Path planning of parallel manipulators in configuration space [PDF]

open access: yes, 2017
Path planning for parallel manipulators, especially for manipulators greater than three degrees of freedom (DOF) is a challenging task for many reasons.

The Parallel Manipulation Argument [PDF]

open access: yesEthics, 2016
Matt King has recently argued that the manipulation argument against compatibilism does not succeed by employing a dilemma: either the argument infelicitously relies on incompatibilist sourcehood c...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Layered and Decoupled Calibration: A High-Precision Kinematic Identification for a 5-DOF Serial-Parallel Manipulator with Remote Drive

open access: yesActuators
Serial-parallel hybrid manipulators featuring remote actuation via parallelogram mechanisms are highly valued for their low inertia and high stiffness.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Topological analysis of singularity loci for serial and parallel manipulators [PDF]

open access: yes, 2008
Singularities of robot manipulators have been intensely studied in the last decades by researchers of many fields. Serial singularities produce some local loss of dexterity of the manipulator, therefore it might be desirable to search for ...

混合型三维移动并联机构及其运动学分析

open access: yesJixie chuandong, 2000
In order to enrich mechanism models of spatial parallel manipulators, two novel models of 3-DOF parallel manipulators are presented. One of them is composed of two CRR limbs and one SPS limb, another is composed of two CPR limbs and one SPS limb.
