Rattlers’ involvement for possibly looser critical states under higher mean stress

نویسندگان

چکیده

The critical state of a granular material made rounded tetrahedral particles is studied through DEM simulations triaxial compressions. A minimum number 7,500 first obtained as the representative volume element (RVE) for present simulations. Then, macroscopic line (CSL) shown to be increasing in (stress, density) space low confining pressures. Such an unexpected behaviour explained by existence significant proportion rattlers. Considering rattlers voids indeed reinstates classically decreasing CSL.

Statistical Inference for the Mean Outcome Under a Possibly Non-Unique Optimal Treatment Strategy

We consider challenges that arise in the estimation of the value of an optimal individualized treatment strategy defined as the treatment rule that maximizes the population mean outcome, where the candidate treatment rules are restricted to depend on baseline covariates. We prove a necessary and sufficient condition for the pathwise differentiability of the optimal value, a key condition needed...

Plants under Stress: Involvement of Auxin and Cytokinin

Plant growth and development are critically influenced by unpredictable abiotic factors. To survive fluctuating changes in their environments, plants have had to develop robust adaptive mechanisms. The dynamic and complementary actions of the auxin and cytokinin pathways regulate a plethora of developmental processes, and their ability to crosstalk makes them ideal candidates for mediating stre...

The microchannel flow model under shear stress and higher frequencies.

The microchannel flow model provides a framework for considering the effect of the vascular bed on the time domain and frequency domain response of soft tissues. The derivation originates with a single small fluid-filled vessel in an elastic medium under uniaxial compression. A fractal branching vasculature is also assumed to be present in the tissue under consideration. This note considers two...

Emotional Memory Formation Under Lower Versus Higher Stress Conditions

An exposure to stress can enhance memory for emotionally arousing experiences. The phenomenon is suggested to be amygdala-dependent and in accordance with that view the amygdala was found to modulate mnemonic processes in other brain regions. Previously, we illustrated increased amygdala activation and reduced activation of CA1 following spatial learning under higher versus lower stress conditi...
