Fusing Multiscale Charts into 3D ENC Systems Based on Underwater Topography and Remote Sensing Image

open access: yes, 2015
The purpose of this study is to propose an approach to fuse multiscale charts into three-dimensional (3D) electronic navigational chart (ENC) systems based on underwater topography and remote sensing image.

A Gravity Model of Migration between Enc and EU

open access: yesSocial Science Research Network, 2013
Due to ageing population and low birth rates, the European Union (EU) will need to import foreign labour in the next decades. In this context, the EU neighbouring countries (ENC) are the main countries of origin and transit of legal and illegal migration

Deniers and Compliers: Unpacking the Heterogeneous Effectiveness of U.S. Stay‐at‐Home Mandates During the COVID‐19 Pandemic

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT While existing work shows COVID‐19 stay‐at‐home (SAH) policies decreased mobility on average, we lack evidence regarding heterogeneity in policy effectiveness across US counties. To uncover potential heterogeneity, we implement a novel two‐stage approach.

ENC-GC3 plot.

open access: yes, 2015
Correlation between GC3 and the effective codon usage statistic (ENC) among (a) S segment, (b) M segment and (c) L segment. The red line represents the ENC expected values (ENC*) and the ENC values are shown in blue.

Anisotropic nonlinear diffusion with absorption: existence and extinction

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
The authors prove that the nonlinear parabolic partial differential equation ∂u∂t=∑i,j=1n∂2∂xi∂xjφij(u)−f(u) with homogeneous Dirichlet boundary conditions and a nonnegative initial condition has a nonnegative generalized solution u.

Analysis on Aigis‐Enc: Asymmetrical and symmetrical

open access: yesIET Information Security, 2021
Aigis‐Enc is an encryption algorithm based on asymmetrical learning with errors (LWE). A thorough comparison between Aigis‐Enc (with the recommended parameters) and a symmetrical LWE encryption scheme on the same scale (the sampling parameters are {η1 ...

A Note on Extendable Sets of Colorings and Rooted Minors

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT DeVos and Seymour proved that for every set C $C$ of 3‐colorings of a set X $X$ of vertices, there exists a plane graph G $G$ with vertices of X $X$ incident with the outer face such that a 3‐coloring of X $X$ extends to a 3‐coloring of G $G$ if and only if it belongs to C $C$.

SubDIVIDE: Efficient tensor‐valued diffusion magnetic resonance imaging via joint diffusional variance decomposition modeling and subspace reconstruction

open access: yesJournal of Intelligent Medicine, EarlyView.
SubDIVIDE integrates a physics‐consistent DIVIDE subspace directly into MRI reconstruction. By embedding a low‐rank basis derived from a large DIVIDE signal dictionary into a joint ADMM optimization—together with composite sensitivity maps that absorb inter‐b‐value phase errors—the framework recovers quantitative microstructural maps from highly ...

Optimized Gradient Waveforms for Tensor‐Valued Diffusion MRI Under Time‐Dependent Diffusion Using Double‐Isotropic Matched Encoding (DIME)

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Spherical and linear b‐tensor encoding (STE and LTE) enables quantification of microscopic diffusion anisotropy and diffusional variance. However, such waveforms are often variably sensitive to time‐dependent diffusion, causing rotational variance and spectral mismatch.
