Recently, sparse coding has been widely used in many applications ranging from image recovery to pattern recognition. The low mutual coherence of a dictionary is an important property that ensures the optimality of the sparse code generated from this dictionary. Indeed, most existing dictionary learning methods for sparse coding either implicitly or explicitly tried to learn an incoherent dicti...

Coherent and incoherent scattering cross section measurements have been carried out using a HPGe detector on elements in the range of Z = 13 50 using Am gamma rays. The cross sections have been derived by comparing the net count rate obtained from the Compton peak of aluminium with the corresponding peak of the target. The measured cross sections for the coherent and incoherent processes are co...

The mean and variance of the acoustic field forward propagated through a stratified ocean waveguide containing three-dimensional 3-D random internal waves is modeled using an analytic normal mode formulation. The formulation accounts for the accumulated effects of multiple forward scattering. These lead to redistribution of both coherent and incoherent modal energies, including attenuation and ...

The energy flux formulation of waveguide propagation is closely related to the incoherent mode sum, and its simplicity has led to development of efficient computational algorithms for reverberation and target echo strength, but it lacks the effects of convergence or modal interference. By starting with the coherent mode sum and rejecting the most rapid interference but retaining beats on a scal...

Traditionally, multitask learning (MTL) assumes that all the tasks are related. This can lead to negative transfer when tasks are indeed incoherent. Recently, a number of approaches have been proposed that alleviate this problem by discovering the underlying task clusters or relationships. However, they are limited to modeling these relationships at the task level, which may be restrictive in s...

We investigate the propagation of partially coherent beams in spatially nonlocal nonlinear media with a logarithmic type of nonlinearity. We derive analytical formulas for the evolution of the beam parameters and conditions for the formation of nonlocal incoherent solitons.

In a previous set of experiments we showed that audio-visual fusion during the McGurk effect may be modulated by context. A short context (2 to 4 syllables) composed of incoherent auditory and visual material significantly decreases the McGurk effect. We interpreted this as showing the existence of an audiovisual “binding” stage controlling the fusion process, incoherence producing “unbinding”,...

We give a classical geometric optics description of incoherent solitons—those launched by a diffuse source. This method is intuitive, advances predictions such as the existence of solitons of arbitrary cross section, and importantly, it provides a simple (universal) analytical description for the incoherent solitons of any nonlinear medium. Previously, analytical results were known for the ln I...

The presence of correlations in the input state a non-interacting many-body quantum system can lead to an increase amount work we extract from it under global unitary processes (ergotropy). present explore such effect on translationally invariant systems relaying Matrix Product Operator formalism define measure how much they are correlated. We observe that thermodynamic limit large number sites...

In this paper, we integrate transcriptional and posttranscriptional regulation into microRNAmediated incoherent feedforward motifs and analyze their dynamical behaviors and functions. The analysis show that the behaviors of the system are almost uninfluenced by the varying input in certain ranges and the introducing of delay and noise. The results indicate that microRNA-mediated incoherent feed...
