‎The aim of this paper is to establish the equivalence between the concepts‎ ‎of an $S$-metric space and a cone $S$-metric space using some topological‎ ‎approaches‎. ‎We introduce a new notion of a $TVS$-cone $S$-metric space using‎ ‎some facts about topological vector spaces‎. ‎We see that the known results on‎ ‎cone $S$-metric spaces (or $N$-cone metric spaces) can be directly obtained‎ from...

1. Spectral sensitivity measurements using the suction electrode technique reveal three types of cone in the retina of the tiger salamander, showing maximum sensitivity at wavelengths 610 nm (red-sensitive cone), 444 nm (blue-sensitive cone) and below 400 nm (UV-sensitive cone). 2. The absolute sensitivities of red- and blue-sensitive cones to flashes of optimal wavelength are 0.022 and 0.33 pA...

Problems concerning complete structural characterization of quasicrystals involve locating the atomic positions as well as determining the distribution of elements at each site. Quasicrystalline approximants provide models for potential building units of quasicrystals, but a clear determination of the elemental decorations in such approximants also remains incomplete. We report experimental and...

This paper explores the link between the presence of unions in the workplace, the adoption of decentralized labor agreements and technical efficiency, using a large sample of Italian manufacturing firms. We apply the Data Envelopment Analysis, and its robust version based on bootstrap theory, to get reliable estimates of technical efficiency at the firm level in a standard first stage. We devot...

The first part of this paper is concerned with global characterizations of both the multivariate ß-spline and the multivariate truncated power function as smooth piecewise polynomials. In the second part of the paper we establish combinatorial criteria for the linear independence of multivariate ß-splines corresponding to certain configurations of knot sets.

Our theorems are on ordered cone metric spaces which are not necessarily normal. In the end, we describe the application of the main results in the integral equation.Although Du in [W‎. ‎S‎. ‎Du‎, ‎A note on cone metric fixed point theory and its equivalence‎, ‎Nonlinear Analysis‎, ‎72(2010) 2259-2261.]‎, ‎showed that the fixed point results in the setting of cone...

We explicate the combinatorial/geometric ingredients of Arthur's proof convergence and polynomiality, in a truncation parameter, his non-invariant trace formula. Starting with fan real, finite dimensional, vector space collection functions, one for each cone fan, we introduce combinatorial truncated function respect to polytope normal prove analogues results on polynomiality integral this over ...

In the existing literature of Mutual Visibility problem for autonomous robot swarms, adopted visibility models have some idealistic assumptions that are not consistent with practical sensing device implementations. This paper investigates in more realistic model called opaque fat robots slim omnidirectional camera. The modeled as unit disks, each having an camera represented a disk smaller size...

Regulation of neural protein kinase C (PKC) activity appears to directly affect the persistence of long-term potentiation (LTP; Akers and Routtenberg, 1985; Lovinger et al., 1985, 1986, 1987; Routtenberg et al., 1985, 1986; Akers et al., 1986; Linden et al., 1987), a model of neural plasticity (Bliss and Lomo, 1973). In addition, the in vitro phosphorylation of a brain-specific PKC substrate, p...
