Some results in the new direction of multiplicative metric space

Boletim da Sociedade Paranaense de Matemática
Inspired by the recent work of Stojan Radenovi\'c and Bessem Samet \cite{stojan new direction}, we prove some fixed point theorems in multiplicative metric space which are not equivalent to the corresponding theorems in standard metric space using the function \(\varphi : [1, \infty) \to [0, \infty)\) that satisfies the condition: $ \varphi(s) \geq b (\

Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization

Advanced Functional Materials, EarlyView.
We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a

Bounded-Distortion Metric Learning

, 2016
Metric learning aims to embed one metric space into another to benefit tasks like classification and clustering. Although a greatly distorted metric space has a high degree of freedom to fit training data, it is prone to overfitting and numerical ...

Sublinear Metric Steiner Tree via Improved Bounds for Set Cover [PDF]

We study the metric Steiner tree problem in the sublinear query model. In this problem, for a set of n points V in a metric space given to us by means of query access to an n× n matrix w, and a set of terminals T ⊆ V, the goal is to find the minimum ...

Remarks on Multiplicative Metric Spaces and Related Fixed Points

, 2015
In this article we studied the relationship between metric spaces and multiplicative metric spaces. Also, we pointed out some fixed and common fixed point results under some contractive conditions in multiplicative metric spaces can be obtained from the corresponding results in standard metric spaces.

Thermally Pre‐Formed Reconfigurable Resistive Random‐Access Memory Crossbar Arrays: A Dual‐Mode Platform for Robust Physically Unclonable Functions and In‐Memory Computing

Advanced Functional Materials, EarlyView.
A reconfigurable RRAM platform utilizing thermally pre‐formed filaments (TPFs) is developed to realize robust hardware security. By exploiting the thermodynamic stochasticity of TPFs, exceptionally reliable physically unclonable functions (PUFs) are achieved.

A Versatile Microfluidic Extrusion‐Based Hydrogel Platform for Self‐Organization and Long‐Term Maintenance of Engineered 3D Lymphatic Endothelium

Advanced Healthcare Materials, EarlyView.
Microfluidic coaxial extrusion generates size‐controlled 3D lymphatic tubes from primary human dermal lymphatic endothelial cells in a defined four‐component matrix. These engineered vessels self‐organize into stable lymphatic endothelium, maintain selective macromolecular permeability for 30 days, and enable direct comparison with blood endothelial ...

MULTIPLICATIVE CHAOS AND DIMENSION OF A MEASURE

Let $ X= {X_k(ω,t)}_{t in T} $, $ k in N $, be an independent sequence of Gaussian processes with mean 0 on a locally compact separable metric space $ (T,d) $, and assume that the covariance functions are non-negative and $ sum _k[X_k( omega ,s) X_k ...

Functor of extension of $\Lambda$-isometric maps between central subsets of the unbounded Urysohn universal space

, 2010
summary:The aim of the paper is to prove that in the unbounded Urysohn universal space $\mathbb U$ there is a functor of extension of $\Lambda $-isometric maps (i.e. dilations) between central subsets of $\mathbb U$ to $\Lambda $-isometric maps acting on
