Topological states can be used to control the mechanical properties of a material along an edge or around a localized defect. The rigidity of elastic networks is characterized by a topological invariant called the polarization; materials with a well-defined uniform polarization display a dramatic range of edge softness depending on the orientation of the polarization relative to the terminating...

Using an exponential model for the variation in energy with respect to the number of electrons it is shown that, within the model, the hardness, softness, electrophilicity and other global parameters connected to higher order derivatives follow an equalization principle after a molecule is formed from two separated species. Two generalizations of the model are also discussed, one of which prese...

Acoustic waves are mechanical waves recently used to activate tissue metabolism by exploiting the cell permeabilization caused by their passage. We report a case of a retroauricular lipoma in a 44-year-old woman affected by multiple symmetric lipomatosis and treated with extracorporeal acoustic wave therapy. The adipose thickness of the lipoma was reduced from 35.8 to 21 mm, with increased soft...

Background We hypothesized that intraluminal signal intensity (SI) of coronary total occlusion (CTO) lesions at coronary MR angiography (CMRA) may reflect the degree of the softness of the lesion with or without the presence of microvessels. The purposes of our study were to report the CMRA findings of CTO lesions and to compare success rates of percutaneous coronary intervention (PCI) for CTO ...

Elastoplastic lattice models for the response of solids to large-scale deformation typically incorporate structure only implicitly via a local yield strain that is assigned each site. However, can change in nearby or even distant plastic event system. This interplay key understanding phenomena such as avalanches which one trigger another, leading cascade events, but neglected elastoplastic mode...

The effects of Y and Nb addition on thermal stability, glass-forming ability (GFA), magnetic softness Co75B25 metallic glass (MG) were comprehensively investigated. experimental results indicated that the GFA, studied MGs increase in order < Co73Nb2B25 Co71.5Y3.5B25 Co69.5Y3.5Nb2B25. structural origins improved properties revealed by ab initio molecular dynamics (AIMD) simulations density funct...

There are some paradoxes in the SoC industry. Here is the crux of the matter for the analog and fast electrical parts: Innovative products involving SoC development often require usage of the latest technological process, together with a mix of high performance logic and analog functions. Reducing cost, time and risk of SoC designs requires the re-use of Virtual Components. Well, re-use clearly...

In many application domains (e.g., WWW mining, molecular biology), large string datasets are available and yet under-exploited. The inductive database framework assumes that both such datasets and the various patterns holding within them might be queryable. In this setting, queries which return patterns are called inductive queries and solving them is one of the core research topics for data mi...
