We consider the slow and athermal deformations of amorphous solids and show how the ensuing sequence of discrete plastic rearrangements can be mapped onto a directed network. The network topology reveals a set of highly connected regions joined by occasional one-way transitions. The highly connected regions include hierarchically organized hysteresis cycles and subcycles. At small to moderate strains this organization leads to near-perfect return point memory. The transitions in the network can be traced back to localized particle rearrangements (soft spots) that interact via Eshelby-type deformation fields. By linking topology to dynamics, the network representations provide new insight into the mechanisms that lead to reversible and irreversible behavior in amorphous solids.

This article focuses on the relevance of amorphous calcium (and magnesium) phosphates in living organisms. Although crystalline calcium phosphate (CaP)-based materials are known to constitute the majo...
Group 6 transition metal dichalcogenides (TMDs), such as MoS and WS have been extensively studied for various applications while few studies have delved into other TMDs such as platinum dichalcogenide...
Co-amorphous technology was recently introduced to stabilize drugs in the amorphous state for drug development. We examined the predictability of the formation of co-amorphous systems, and identified ...
This review identifies two cognitive benefits of social hierarchy that may contribute to hierarchy maintenance. First, research indicates that people pay attention to hierarchies automatically, early,...
This study is to investigate the bioavailability of a hot-melt extruded amorphous solid dispersion formulation of Efavirenz compared to a marketed formulation(Stocrin®).
The purpose of the research is to learn whether written materials or handouts that are given to parents are helpful in changing knowledge or behavior.

Patients diagnosed with, or in risk of osteoporosis regularly take calcium dietary supplements, although their contribution to BMD maintenance, prevention of bone loss or reduction of the ...
Assess the effectiveness of applying grape seed extract (GSE) gel versus casein phosphopeptide-amorphous calcium phosphate (MI) paste on remineralization of white spot lesion (WSLs) in pos...
The transport of materials through a cell. It includes the uptake of materials by the cell (ENDOCYTOSIS), the movement of those materials through the cell, and the subsequent secretion of those materials (EXOCYTOSIS).
An interdisciplinary study of the microstructure and composition of various materials such as metals, semiconductors, ceramics, and polymers, in relation to their macromolecular physical and chemical properties. Materials science enables the custom creation of new materials with specific properties and uses.
Substances used to create an impression, or negative reproduction, of the teeth and dental arches. These materials include dental plasters and cements, metallic oxide pastes, silicone base materials, or elastomeric materials.
Materials placed inside a root canal for the purpose of obturating or sealing it. The materials may be gutta-percha, silver cones, paste mixtures, or other substances. (Dorland, 28th ed, p631 & Boucher's Clinical Dental Terminology, 4th ed, p187)
