An Efficient and Robust Current Control for Polymer Electrolyte Membrane Fuel Cell Power System
(MDPI, 2021-02-22)
Taking into account the restricted ability of polymer electrolyte membrane fuel cell (PEMFC) to generate energy, it is compulsory to present techniques, in which an efficient operating power can be achieved. In many ...
Fractional Coupled Hybrid Sturm–Liouville Differential Equation with Multi-Point Boundary Coupled Hybrid Condition
(MDPI, 2021-04-16)
The Sturm–Liouville differential equation is an important tool for physics, applied mathematics, and other fields of engineering and science and has wide applications in quantum mechanics, classical mechanics, and wave ...
Coupled Optimal Results with an Application to Nonlinear Integral Equations
(MDPI, 2021-04-22)
In the present work, we consider the best proximal problem related to a coupled mapping, which we define using control functions and weak inequalities. As a consequence, we obtain some results on coupled fixed points. Our ...
Radu–Miheţ Method for the Existence, Uniqueness, and Approximation of the ψ-Hilfer Fractional Equations by Matrix-Valued Fuzzy Controllers
(MDPI, 2021-04-16)
We apply the Radu–Miheţ method derived from an alternative fixed-point theorem with a class of matrix-valued fuzzy controllers to approximate a fractional Volterra integro-differential equation with the ψ-Hilfer fractional ...
Magnetic Nanoparticles Hyperthermia in A Non-Adiabatic and Radiating Process
(Nature, 2021-06-04)
We investigate the magnetic nanoparticles hyperthermia in a non-adiabatic and radiating process through the calorimetric method. Specifically, we propose a theoretical approach to magnetic hyperthermia from a thermodynamic ...
Visual Perception and the Emergence of Minimal Representation
(Frontiers Media, 2021-05-17)
There is a long-lasting quest of demarcating a minimally representational behavior. Based on neurophysiologically-informed behavioral studies, we argue in detail that one of the simplest cases of organismic behavior based ...
Investigation of the Biological Activity, Mechanical Properties and Wound Healing Application of a Novel Scaffold Based on Lignin–Agarose Hydrogel and Silk Fibroin Embedded Zinc Chromite Nanoparticles
(Royal Society Of Chemistry, 2021-05-27)
Given the important aspects of wound healing approaches, in this work, an innovative biocompatible nanobiocomposite scaffold was designed and prepared based on cross-linked lignin-agarose hydrogel, extracted silk fibroin ...
Assessing the role of evidence of mechanisms in causal extrapolation
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2021)
Extrapolation of causal claims from study populations to other populations of interest is a problematic issue. The standard approach in experimental research, which prioritises randomized controlled trials and statistical ...
Newton’s experimental proofs
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2021)
Newton claims that his theorems in the Opticks are derived from experiments alone. The paper explains this dictum by relating Newton’s proof method to an iconic conception of proof as opposed to a symbolic one. Theorems ...
Mechanisms, good and bad
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2021)
The claim that mechanisms are essential good science is widespread. I argue, however, that these claims are ambiguous in multiple ways. I sort out different version of the mechanism idea: (1) mechanisms that are horizontal ...
