A rate-state model for aftershocks triggered by dislocation on a rectangular fault: a review and new insights
aftershocks earthquake triggering fault parameters rate-and-state Omori law
2015/9/8
We compute the static displacement, stress, strain and the Coulomb failure stress produced in
an elastic medium by a finite size rectangular fault after its dislocation with uniform stress drop
but ...
Posterolateral Elbow Dislocation with Ipsilateral Fractures of Head and Distal End Radius
Elbow joint dislocation Radial head Distal end radius fracture Closed reduction
2015/7/21
Elbow dislocation associated with ipsilateral fracture head and distal end radius is a rare pattern of Injury, although it is common for elbow dislocation and radius fractures to occur separately. We ...
A Palmar Fracture-Dislocation of the Proximal Interphalangeal Joint of the Middle Finger Caused by Bowling: A Case Report
Palmal fracture-dislocation PIP joint bowling sports
2015/4/21
During bowling, a twenty year old man could not pull out his middle finger from the ball in release and injured his finger. X-ray revealed a palmar fracture- dislocation of the PIP joint. We manipulat...
Luttinger Liquid in the Core of a Screw Dislocation in Helium-4
Monte carlo simulation hexagonal shaft screw crystals superfluids screw dislocation
2014/12/20
On the basis of first-principles Monte Carlo simulations we find that the screw dislocation along the hexagonal axis of an hcp 4He crystal features a superfluid (at T→0) core. This is the first exampl...
Binding of a 3He Impurity to a Screw Dislocation in Solid 4He
Based on simulation the probability density solid atom the nucleus
2014/12/19
Using first-principles simulations for the probability density of finding a 3He atom in the vicinity of the screw dislocation in solid 4He, we determine the binding energy to the dislocation nucleus E...
Molecular-dynamics Simulations of Stacking-fault-induced Dislocation Annihilation in Pre-strained Ultrathin Single-crystalline Copper Films
Molecular dynamics dynamic deformation metal structure
2014/12/19
We report results of large-scale molecular-dynamics (MD) simulations of dynamic deformation under biaxial tensile strain of pre-strained single-crystalline nanometerscale- thick face-centered cubic (f...
Unusual Double Dislocation of Both Joints in a Same Finger:A Case Report
IP Joints MCP Joints Dislocation Finger
2015/10/9
Simultaneous dislocation of both interphalangeal (IP) joints of same finger is a highly uncommon finding. And dislocation of metacarpophalangeal (MCP) joint along with interphalangeal joints of thumb ...
A generalized Peierls-Nabarro model for curved dislocations and core structures of dislocation loops in Al and Cu
Dislocation dislocation structures micromechanical modeling Peierls-Nabarro model
2012/8/8
In this paper, we present a generalized Peierls-Nabarro model for curved dislo-
cations. In the generalized Peierls-Nabarro model, the anisotropic elastic energy is
obtained e±ciently by solving the...
Dislocation-mediated growth of bacterial cell walls
Cell wall growth Biophysics Defects Biological Physics
2012/5/29
Recent experiments have illuminated a remarkable growth mechanism of rod-shaped bacteria: proteins associated with cell wall extension move at constant velocity in circles oriented approximately along...
Practical implications of the geometrical sensitivity of elastic dislocation models for field geologic surveys
Subduction zone seismic cycle deformation Sensitivity to plate geometry and slip distribution Coastal uplift and hingeline Elastic subducting plate model Backslip model Geodetic data inversion
2014/4/9
Geodetic observations of both coseismic and interseismic surface deformationfields in the vicinity of subduction zones are frequently interpreted using simple elastic dislocation models (EDMs). The ge...
Entropic Effect on the Rate of Dislocation Nucleation
Entropic Effect the Rate of Dislocation Nucleation
2010/11/18
Dislocation nucleation is essential to our understanding of plastic deformation, ductility and
mechanical strength of crystalline materials. Molecular dynamics simulation has played an important role...
A variational approach to dislocation problems for periodic Schrödinger operators
Schr¨odinger operators eigenvalues spectral gaps
2010/12/8
As a simple model for lattice defects like grain boundaries in solid state physics we consider potentials which are obtained from a periodic potential V = V (x, y) on R2 with period lattice Z2 by sett...
A comparison of the treatment of developmental dislocation of the hip in the older children by femoral shortening with a) Acetabular shelf and b) Innominate osteotomy plus shelf
Developmental dislocation of the hip delayed diagnosis acetabuloplasty techniques
2010/2/24
The surgical treatment of childhood developmental dislocation of the hip with delayed diagnosis is difficult. However, it can be concluded that, in patients 7 years old or younger with a diagnosis of ...
