Impact of intraoparetive parametres on survival of patients with ruptured abdominal aortic aneurysm [PDF]
Ruptured abdominal aortic aneurysm is one of the most urgent surgical conditions with high mortality that has not been changed in decades. Between 1991-2001 total number of 1058 patients was operated at the Institute for Cardiovascular Diseases of ...

How does dissipation affect the transition from static to dynamic macroscopic friction? [PDF]
Description of the transitional process from a static to a dynamic frictional regime is a fundamental problem of modern physics. Previously we developed a model based on the well-known Frenkel-Kontorova model to describe dry macroscopic friction.

Suspensory Tethers and Critical Point Membrane Displacement in Endolymphatic Hydrops
Introduction Grossly displaced membranes are characteristic of endolymphatic hydrops. The process whereby physiological membrane displacement becomes pathological may be mediated by stress, but the membrane biomechanics underlying this transition are ...

A window into the complexity of the dynamic rupture of the 2011 Mw 9 Tohoku-Oki earthquake [PDF]
The 2011 Mw 9 Tohoku-Oki earthquake, recorded by over 1000 near-field stations and multiple large-aperture arrays, is by far the best recorded earthquake in the history of seismology and provides unique opportunities to address fundamental issues in ...

Creep Characterization of Inconel 718 Lattice Metamaterials Manufactured by Laser Powder Bed Fusion
Herein, the creep characteristics of additively manufactured Inconel 718 metamaterials are investigated. The creep behavior of metamaterials and the effects of microstructural defects are assessed, and the microstructure defects are accurately captured using Kachanov's creep damage model.

Architected Lattices with a Topological Transition
This article develops topological metamaterials showing multidirectional two‐step deformation under compression by embedding contact‐enabled topological mechanisms into lattice structures. Experiments on 3D‐printed 2D and 3D lattices and finite element simulations are conducted to demonstrate the working principle of the topological metamaterials.

Subcritical crack growth in fibrous materials [PDF]
We present experiments on the slow growth of a single crack in a fax paper sheet submitted to a constant force $F$. We find that statistically averaged crack growth curves can be described by only two parameters : the mean rupture time $\tau$ and a ...
