Elastic-contact-based tool-path planning for free-form surface in belt grinding
Advances in Mechanical Engineering, 2019 As for the fact that the majority of current researches take the technology of tool-path planning for free-form surface only as a geometrical problem, which is not suitable for belt grinding because of the elastic deformation of the grinding belt that ...

Algorithms for optimal min hop and foremost paths in interval temporal graphs
Applied Network Science, 2022 Path problems are fundamental to the study of graphs. Temporal graphs are graphs in which the edges connecting the vertices change with time. Min hop paths problem in a temporal graph is the problem of finding time respecting paths from source vertex to ...

The Binary Contact Path Process
The Annals of Probability, 1983 We study some $\{0, 1, \cdots\}^{z^d}$ valued Markov interactions $\eta_t$ called contact path processes. These are similar to branching random walks, in that the normalized size process starting from a singleton is a martingale which converges to a limit $M_\infty$.

Numerical tooth contact analysis of gear transmissions through the discretization and adaptive refinement of the contact surfaces [PDF]
, 2016 The tooth contact analysis (TCA) is an important resource for the design of gear drives. This widely used analysis provides the contact pattern, contact path and the function of transmission errors that are directly related to the performance of the gear

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.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
