Motivated by the experiments [Santamaria, Neuron 52, 635 (2006)10.1016/j.neuron.2006.10.025] that indicated the possibility of subdiffusive transport of molecules along dendrites of cerebellar Purkinje cells, we develop a mesoscopic model for transport and chemical reactions of particles in spiny dendrites. The communication between spines and a parent dendrite is described by a non-Markovian r...

Melting of a bicrystal along the grain boundary is discussed. A triple junction plays a crucial role in the velocity selection problem in this case. In some range of the parameters an entirely analytical solution of this problem is given. This allows us to present a transparent picture of the structure of the selection theory. We also discuss the selection problem in the case of the growth of a...

A facile, green and environmental-friendly method for preparing Cu1.8S dendrites was developed. Copper nitrate and thiamine hydrochloride were selected as the starting materials in the water phase under hydrothermal conditions. No addition of a surfactant or a complex reagent was required for the synthesis of the Cu1.8S dendrite structures. Thiamine hydrochloride was employed as a sulfur source...

Abstract High entropy alloy is considered a kind of structural and functional materials with wide application prospects. In the present work, FeCrCoNiMo x was prepared used as research object. The influence Mo large atomic radius on crystal structure, microstructure, mechanical properties discussed variation microstructure composition clarified. changes gradually from single phase FCC centered ...

Inconel 718 alloys were fabricated by selective laser melting under different scanning speeds to investigate the change of morphology molten pool, direction grain growth, and tensile properties. Results show that as speed increases from 1,000 1,450 mm·s−1, ratio between depth width pool increases, yet their overlapping regimes decrease. Meanwhile, increasing can promote solidified structure evo...

Formation of neural circuits depends on stable contacts between neuronal processes, mediated by interaction of cell adhesion molecules, including N-cadherin. In the present study, we found that activity-dependent dendrite arborization specifically requires N-cadherin-mediated extracellular neuron-neuron interaction, because the enhancement did not occur for neurons cultured in isolation or plat...

High brilliance synchrotron X-ray radiography has been used to in situ study the solidification process of Al­20mass%Cu alloy with nominal spatial and temporal resolutions of 7.4 μm and 300ms, respectively. The block of favorably oriented dendrites by the unfavorably oriented ones was first observed in metal solidification, which related to solute interaction of neighbor dendrites. Solute inter...

The functioning of the neuronal dendrite results from a variety of biological processes including mRNA transport to and protein translation in the dendrite. The complexity of the mRNA population in dendrites suggests that specific biological processes are modulated through the regulation of dendritic biology. There are various classes of mRNAs in dendrites whose translation modulates the abilit...
