Estimated Errors in |Vcd|/|Vcs| from Semileptonic D Decays

, 1998
We estimate statistical and systematic errors in the extraction of the CKM ratio |Vcd|/|Vcs| from exclusive D-meson semileptonic decays using lattice QCD and anticipated new experimental results.Comment: LATTICE98(heavyqk), LaTeX, 3 pages, 2 postscript ...

Sb2Se3 Thin Films for Doping the Absorber in CdTe Solar Cells

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 3, Page 326-335, March 2026.
This study introduces for the first time a new doping route for CdSeTe/CdTe solar cells: A thin Sb2Se3 layer is deposited on the absorber, diffusing Sb into CdTe via subsequent CdCl2 treatment. With this approach, Sb‐doped devices reach efficiencies as high as conventional Cu‐doped cells, while showing much greater stability under accelerated ...

Reform path and empirical exploration of visual communication design education based on graph neural network

Systems and Soft Computing
With the continuous development of visual communication design (VCD), its design concept is also constantly evolving. Traditional graphic design education is no longer meeting the needs of contemporary design education, making reform essential to improve

Automorphisms of two-dimensional right-angled Artin groups

, 2007
We study the outer automorphism group of a right-angled Artin group A_G in the case where the defining graph G is connected and triangle-free. We give an algebraic description of Out(A_G) in terms of maximal join subgraphs in G and prove that the Tits ...

Text in R graphics

Australian &New Zealand Journal of Statistics, Volume 68, Issue 1, March 2026.
Summary R graphics has provided the ability to draw simple text labels on plots since R version 1.0.0. However, these basic text‐drawing facilities are quite limited. Over the past 25 years, more sophisticated text‐drawing features have been added: support for the Unicode character set; access to system fonts; text paths; support for text markup; and ...

Chiroptical Spectroscopy, Theoretical Calculations, and Symmetry of a Chiral Transition Metal Complex with Low-Lying Electronic States

Molecules
Vibrational circular dichroism (VCD) enhancement by low-lying electronic states (LLESs) is a fascinating phenomenon, but accounting for it theoretically remains a challenge despite significant research efforts over the past 20 years.

$\Lambda_c \to N$ form factors from lattice QCD and phenomenology of $\Lambda_c \to n \ell^+ \nu_\ell$ and $\Lambda_c \to p \mu^+ \mu^-$ decays

, 2018
A lattice QCD determination of the $\Lambda_c \to N$ vector, axial vector, and tensor form factors is reported. The calculation was performed with $2+1$ flavors of domain wall fermions at lattice spacings of $a\approx 0.11\:{\rm fm},\:0.085\:{\rm fm ...

From Psycholinguistics to Computer Vision. A Comprehensive Review of Object Naming Data and Studies

Language and Linguistics Compass, Volume 20, Issue 2, March/April 2026.
ABSTRACT In recent years, much research has focused on what happens in the human brain when a perceptual stimulus, such as a picture, is converted into linguistic content, a word. This process is commonly referred to as object naming and is considered a crucial aspect of language processing, production, and cognition. It refers to the identification of
