Sign-changing solutions for some nonlinear problems with strong resonance

open access: yesBoundary Value Problems, 2011
By means of critical point and index theories, we obtain the existence and multiplicity of sign-changing solutions for some elliptic problems with strong resonance at infinity, under weaker conditions.

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Lectures mathématiques : sédimentation, réactivation ou partage ?

open access: yesMethodos, 2020
Historians of mathematics have often noticed a singularity of their discipline: unlike physics, the history of mathematics does not proceed essentially by conjectures and refutations, but by a succession of reinterpretations of the past in order to ...

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

open access: yesAdvanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

The Role of Infinity with Signs in Mathematics [PDF]

open access: yesEducation Journal, 2013
The article shows the significance of signs +∞ and -∞ (infinity with signs) for a full exposition of some of the problematic materials in mathematics. With its help smoothness of the curve, specified by functions with finite and infinite derivatives at the points, is determined. The properties of the function f, with which you can set the smoothness of

An asymptotically tight bound on the number of semi-algebraically connected components of realizable sign conditions

open access: yes, 2008
We prove an asymptotically tight bound (asymptotic with respect to the number of polynomials for fixed degrees and number of variables) on the number of semi-algebraically connected components of the realizations of all realizable sign conditions of a ...
