Macroscopic limit of the Becker-D\"oring equation via gradient flows
, 2018 This work considers gradient structures for the Becker-D\"oring equation and its macroscopic limits. The result of Niethammer [17] is extended to prove the convergence not only for solutions of the Becker-D\"oring equation towards the Lifshitz-Slyozov ...

Observation of a New Mechanism of Spontaneous Generation of Magnetic Flux in a Superconductor
, 2004 We report the discovery of a new mechanism of spontaneous generation of a magnetic flux in a superconductor cooled through $T_c$. The sign of the spontaneous flux changes randomly from one cooldown to the next, and follows a Gaussian distribution.

Dynamical Systems Approach of Internal Length in Fractional Calculus
Engineering Transactions, 2017 Conventionally, non-local properties are included in the constitutive equations in the form of strain gradient-dependent terms. In case of the second gradient dependence an internal material length can be obtained from the critical eigenmodes in ...

VELOCITY GRADIENT OF THE FLOOR EXERCISE [PDF]
Journal of Applied Sports Sciences, 2019 The methodological classification of the volume of the exercises is in the basis of the multiannual preparation in gymnastics. A number of authors (Dimitrova, 2015; Borisenko, 2000; Fisenko, 2005; Gaverdovskiy, Smolevskiy, 2014) note that for the ...

On the corotation torque in a radiatively inefficient disk
, 2007 We consider the angular momentum exchange at the corotation resonance between a two-dimensional gaseous disk and a uniformly rotating external potential, assuming that the disk flow is adiabatic.

Proton Gradients and Proton-Dependent Transport Processes in the Chloroplast [PDF]
Frontiers in Plant Science, 2016 Proton gradients are fundamental to chloroplast function. Across thylakoid membranes, the light induced -proton gradient is essential for ATP synthesis. As a result of proton pumping into the thylakoid lumen, an alkaline stromal pH develops, which is required for full activation of pH-dependent Calvin Benson cycle enzymes.

Neumann Homogenization via Integro-Differential Operators, Part 2: singular gradient dependence
, 2018 We continue the program initiated in a previous work, of applying integro-differential methods to Neumann Homogenization problems. We target the case of linear periodic equations with a singular drift, which includes (with some regularity assumptions ...

FEBS Letters, EarlyView.Angiotensin II (AngII), a neuropeptide, interacts with amyloid‐β (Aβ), a key player in Alzheimer's disease. This study reveals that AngII reduces Aβ aggregation and membrane disruption in vitro. Biophysical assays and molecular modeling suggest AngII binds disordered Aβ forms, potentially modulating early amyloidogenic events and contributing to ...

Advances in Nonlinear AnalysisIn this paper, we study coupled elliptic systems with gradient dependent right-hand sides and nonlinear boundary conditions, where the left-hand sides are driven by so-called double phase operators.

FEBS Letters, EarlyView.Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...
