In this paper we consider a two-population lattice-Boltzmann algorithm to approximate the advection equation. First, the stability of this model algorithm is examined. The analysis is based on the analytic computation of the spectrum pertaining to the evolution matrix. After proving a necessary stability condition, the stability of the evolution matrix is shown, which is related to the CFL-cond...

The Dementia with Lewy Bodies (DLB) Consortium has refined its recommendations about the clinical and pathologic diagnosis of DLB, updating the previous report, which has been in widespread use for the last decade. The revised DLB consensus criteria now distinguish clearly between clinical features and diagnostic biomarkers, and give guidance about optimal methods to establish and interpret the...

OBJECTIVE Rapid eye movement (REM) sleep behavior disorder (RBD) is commonly associated with Lewy body disease, narcolepsy, or depression. In contrast, the relationship between REM sleep without atonia (RWA), which is a hallmark of RBD on polysomnography, and clinical characteristics remains unclear. The purpose of this study is to investigate the clinical features of psychiatric patients exhib...

BACKGROUND Duration of esthetic treatments may contribute to subject satisfaction. OBJECTIVE Describe response duration with onabotulinumtoxinA in crow's feet lines (CFL) and the association of duration with perception of improvement. METHODS Subjects from 2 double-blind, placebo-controlled trials received onabotulinumtoxinA 24 U in CFL; Study 2 subjects could also receive 20 U in glabella....

Heterogeneous distribution of red blood cells (RBCs) in downstream vessels of arteriolar bifurcations can be promoted by an asymmetric formation of cell-free layer (CFL) in upstream vessels. Consequently, the CFL widths in subsequent downstream vessels become an important determinant for tissue oxygenation (O2) and vascular tone change by varying nitric oxide (NO) availability. To extend our pr...

Chroma from luma (CfL) prediction is a new and promising chroma-only intra predictor that models chroma pixels as a linear function of the coincident reconstructed luma pixels. In this paper, we present the CfL predictor adopted in Alliance Video 1 (AV1), a royaltyfree video codec developed by the Alliance for Open Media (AOM). The proposed CfL distinguishes itself from prior art not only by re...

This paper focuses on large–scale unsupervised feature selection from text. We expand upon the recently proposed Compressive Feature Learning (CFL) framework, a method that uses dictionarybased compression to select a K-gram representation for a document corpus. We show that CFL is NP–Complete and provide a novel and efficient approximation algorithm based on a homotopy that transforms a convex...

From a previous field investigation in Yunnan, southwest China between 2001 and 2015, we selected two types of landscapes to make a retrospectively comparative study on the distribution of small mammals and their ectoparasitic chigger mites. One landscape is "mountainous uncultivated land (MUL)" with higher biodiversity, which is located in a famous "World Nature Heritage Site", the Three-Paral...
