in this paper, we introduce the notion of ($epsilon $, $epsilon $ $vee$ q_{k})− fuzzy subnear-ring which is a generalization of ($epsilon $, $epsilon $ $vee$ q)−fuzzy subnear-ring. we have given examples which are ($epsilon $, $epsilon $ $vee$ q_{k})−fuzzy ideals but they are not ($epsilon $, $epsilon $ $vee$ q)−fuzzy ideals. we have also introduced the notions of ($epsilon $, $epsilon $ $vee$ ...

in this paper, by introducing two virtual decision-making units (dmus) called ideal dmu (idmu) and anti-ideal dmu (admu) with fuzzy inputs-outputs, the efficiency evaluation of dmus are done by fuzzy data envelopment analysis (fdea). therefore, we evaluate dmus from the perspective of the best and worst possible relative efficiency. for each dmu two efficiencies are calculated while inputs and ...

Abstract The aim of this paper is to examine the existence at least two distinct nontrivial solutions a Schrödinger-type problem involving nonlocal fractional $p(\cdot )$ p ( ⋅ ) -Laplacian with concave–convex nonlinearities when, in general, nonlinear term d...

We investigate the trapping of interstellar objects during early stages star and planet formation. Our results show a very wide range possible values that will be narrowed down as population becomes better characterized. When assuming background number density 2$\cdot$10$^{15}$ pc$^{-3}$ (based on 1I/'Oumuamua detection), velocity dispersion 30 km/s an equilibrium size distribution, captured by...

The presence of nonlocal interactions and intermittent signals in the homogeneous isotropic turbulence grant multi-point statistical functions a key role formulating new generation large-eddy simulation (LES) models higher fidelity. We establish tempered fractional-order modeling framework for developing LES subgrid-scale models, starting from kinetic transport. employ L\'evy-stable distributio...

Detection of intensity flashes in the blowfly photoreceptor is limited by photon noise in the input signal as well as noise contributed by transduction components within the photoreceptor. Our analysis uses an ideal observer and a model of blowfly phototransduction to compute the threshold for optimal detection of intensity flashes as background intensity varies. We find that detection threshol...
