Soft fixed point theorems for the soft sup-comparable contractions

Fixed Point Theory and Algorithms for Sciences and Engineering
In this paper, we introduce the notion of soft sup-comparable contraction in the framework of soft metric spaces, and we investigate the existence of soft fixed points for this contraction.

Constructing training set using distance between learnt graphical models of time series data on patient physiology, to predict disease scores.

PLoS ONE, 2023
Interventional endeavours in medicine include prediction of a score that parametrises a new subject's susceptibility to a given disease, at the pre-onset stage.

A metric approach to limit operators

, 2017
We extend the limit operator machinery of Rabinovich, Roch, and Silbermann from Z^N to (bounded geometry, strongly) discrete metric spaces. We do not assume the presence of any group structure or action on our metric spaces.

Iterative QR-Based SFSIC Detection and Decoder Algorithm for a Reed–Muller Space-Time Turbo System

Entropy, 2017
An iterative QR-based soft feedback segment interference cancellation (QRSFSIC) detection and decoder algorithm for a Reed–Muller (RM) space-time turbo system is proposed in this paper. It forms the sufficient statistic for the minimum-mean-square error (

From shockwaves to the gravitational memory effect

Journal of High Energy Physics
We study the relationship between shockwave geometries and the gravitational memory effect in four-dimensional asymptotically flat spacetime. In particular, we show the ’t Hooft commutation relations of shockwave operators are equivalent to the ...

Supervised Classification of Agricultural Land Cover Using a Modified k-NN Technique (MNN) and Landsat Remote Sensing Imagery

Remote Sensing, 2009
Nearest neighbor techniques are commonly used in remote sensing, pattern recognition and statistics to classify objects into a predefined number of categories based on a given set of predictors. These techniques are especially useful for highly nonlinear

Gravitational dual of averaged free CFT’s over the Narain lattice

Journal of High Energy Physics, 2020
It has been recently argued that the averaging of free CFT’s over the Narain lattice can be holographically described through a Chern-Simons theory for U (1) D ×U (1) D with a precise prescription to sum over three-dimensional handlebodies.
