We suggest a novel type of composite spatial optical soliton created by a coherent vortex beam guiding a partially incoherent light beam in a self-focusing nonlinear medium. We show that the incoherence of the guided mode may enhance, rather than suppress, the vortex azimuthal instability, and we also demonstrate strong destabilization of dipole-mode solitons by partially incoherent light.

How do we effectively understand graphical interfaces in order to act in the virtual ambient they create? Metaphors in user interfaces are meant to give the user a familiar context in which to act: an office with recycle bins, desktops, folders and files. The problem is that incoherence lies everywhere if we look beneath

Inconsistency in the framework of general residuated logic programs can be, somehow, decomposed in two notions: incoherence and instability. In this work, we focus on the measure of instability of normal residuated programs. Some measures are provided and initial results are obtained in terms of the amount of information that have to be discarded in order to recover stability.

Understanding of “Coherence” In my understanding, coherence in computer-mediated conversation (CMC) is a logical, consistent, and orderly flow of conversations in electronic environments. Herring (1999) identified two major problems that could cause incoherence in CMC: lack of simultaneous feedback and disrupted turn adjacency. Herring demonstrated the problems by using examples from synchronou...

This paper presents a framework for compressed sensing that bridges a gap between existing theory and the current use of compressed sensing in many real-world applications. In doing so, it also introduces a new sampling method that yields substantially improved recovery over existing techniques. In many applications of compressed sensing, including medical imaging, the standard principles of in...

Purpose: In June 2018, the European Union (“EU”) decided to use missions as tools of innovation policy in accordance with market-shaping, mission-oriented approach. It stemmed from EU’s efforts improve efficiency when it comes handling major social challenges. first quarter 2020, EU had unexpectedly face another challenge, COVID-19 pandemic, and economic crisis that followed. This article analy...
