Gradient Descent-Based Optimization Method of a Four-Bar Mechanism Using Fully Cartesian Coordinates
Applied Sciences, 2019 Machine vibrations often occur due to dynamic unbalance inducing wear, fatigue, and noise that limit the potential of many machines. Dynamic balancing is a main concern in mechanism and machine theory as it allows designers to limit the transmission of ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Balancing a static black ring with a phantom scalar field
Physics Letters B, 2019 All known five dimensional, asymptotically flat, static black rings possess conical singularities. However, there is no fundamental obstruction forbidding the existence of balanced configurations, and we show that the Einstein–Klein-Gordon equations ...

Static Balancing of an Exechon-Like Parallel Mechanism
, 2020 The compensation of gravity loads can represent a convenient strategy to enhance the opera-tion of manipulators with heavy end-effector/moving platform and/or moderate veloci-ties/accelerations, particularly in terms of energy efficiency. This work deals

A screw theory-based methodology for approximate static balancing of mechanisms
, 2023 A statically balanced mechanism remains in equilibrium at any position in its range of motion, which is desirable in many devices since minimal or no actuator action is required to support the weight of the mechanism; furthermore, improved energy ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Centering Performance Analysis of Static Balancing Measure for Marine Propeller
, 2011 The working principle of the fully hydraulic static balancing machine with high accuracy is introduced, which is used to check marine propeller balance degree. First of all, the measuring precision of the apparatus is discussed, which is usually effected
