A constitutive model of bulk metallic glass (BMG) plasticity is developed which accounts for finitedeformation kinematics, the kinetics of free volume, strain hardening, thermal softening, rate-dependency and non-Newtonian viscosity. The model has been validated against uniaxial compression test data; and against plate bending experiments. The model captures accurately salient aspects of the ma...

AIMS Echocardiographic speckle tracking or two-dimensional (2D) strain analysis is a new tool to assess myocardial function. This prospective controlled study evaluates systolic right ventricular (RV) function by 2D strain in adult patients with atrial septal defect (ASD) before and 3 months after percutaneous closure. METHODS AND RESULTS Assessment of global longitudinal strain (GLS), global...

We study the quasistatic behavior of the lamellar phase of diblock copolymers under uniaxial compression and tension along the normal direction of the layers, in both the weak segregation limit (WSL) and the strong segregation limit (SSL). In the SSL, we derive a (nonlinear) continuum free energy description of the system in terms of local displacement of the lamellar layers, and use this free ...

The interaction of the Gram-negative bacterium Stenotrophomonas maltophilia with eukaryotes can improve overall plant growth and health, but can also cause opportunistic infections in humans. While the quorum sensing molecule DSF (diffusible signal factor) is responsible for the regulation of phenotypes in pathogenic Stenotrophomonas, up until now, no beneficial effects were reported to be cont...

During mesenchymal condensation, the initial step of skeletogenesis, transduction of minute mechanical forces to the nucleus is associated with up or down-regulation of genes, ultimately resulting in formation of the skeletal template and appropriate cell lineage commitment. The summation of these biophysical cues affects the cell's shape and fate. Here, we predict and measure surface strain, i...

Forearc basin controlled by complex interplay oblique subduction, rise an outer forearc high, tectonic escape. Post-accretion strain partitioning across wedge with varying trench-parallel oriented deformation.

background: opiate is used in patient-controlled intravenous analgesia pumps (pcia) for controlling pain in post-surgical patients.other drugs are remarkably added to opioid pumps to enhance quality, lengthen analgesia, and reduce side effects. lidocaine, a local anesthetic which inhibits sodium channels, has anesthetic and analgesic effects when injected locally or intravenously. the objective...

background: deliberate hypotension is a strategy that reduces intraoperative bleeding and increases the speed of surgery in otolaryngology procedures. magnesium (mg) sulfate is a vasodilator agent that reduces intraoperative hypnotic requirements and in combination with analgesic agents, it reduces intraoperative and postoperative pain. in this study we evaluated the use of intravenous mg sulfa...

Indentation tests were used for early detection of deformation-induced damage Inconel 718. Damage was produced in a controlled manner using specially designed specimens with variable width the gage part. Static tension, LCF, and HCF performed to induce material damage. Accumulated plastic strain intensity as reference measure Detection progress its phase based on use strain-hardening cross-effe...

Predicting the behavior of complex systems is one main goals science. An important example plastic deformation micron-scale crystals, a process mediated by collective dynamics dislocations, manifested as broadly distributed strain bursts and significant sample-to-sample variations in response to applied loading. Here, combining large-scale discrete dislocation simulations machine learning, we s...
