Kinematic Analysis of a 3-Axis Parallel Manipulator: The P3
Advances in Mechanical Engineering, 2013 This paper presents kinematic analysis of a 3-axis parallel manipulator, called P3. The P3 parallel manipulator is developed based on a 3-PRRU parallel mechanism, where P denotes prismatic pair, R revolute pair, and U universal joint.

The Parallel Manipulation Argument [PDF]
Ethics, 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...

Stiffness analysis of overconstrained parallel manipulators [PDF]
Mechanism and Machine Theory, 2009 The paper presents a new stiffness modeling method for overconstrained parallel manipulators with flexible links and compliant actuating joints. It is based on a multidimensional lumped-parameter model that replaces the link flexibility by localized 6-dof virtual springs that describe both translational/rotational compliance and the coupling between ...

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

FEBS Letters, EarlyView.Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.
