Atomic Data for Permitted Resonance Lines of Atoms and Ions from H to Si, and S, Ar, Ca and Fe

open access: yes, 1996
We list vacuum wavelengths, energy levels, statistical weights, transition probabilities and oscillator strengths for permitted resonance spectral lines of all ions of 18 astrophysically important elements (H through Si, S, Ar, Ca, Fe).

Precise Quantification of Angiogenesis in 3D Biomaterials Using in Vitro CAM Models: Enhancing 3Rs in Research and Minimizing in Vivo Dependency

open access: yesAdvanced Functional Materials, EarlyView.
The study develops elastin–fibrin scaffolds and evaluates angiogenesis using the chorioallantoic membrane (CAM) model. Advanced imaging with confocal microscopy and Indocyanine Green dye enables precise 3D quantification of vascular networks. Findings demonstrate superior microvessel visualization compared to micro‐CT using Microfil and Optiray 350 ...

Aspects of Bandi tonology

open access: yesStudies in African Linguistics, 1991
Bandi tonology offers three points of interest. The first is low tone opacity. Several tone rules act to obscure the presence of underlying low tones in Bandi.

Complexity and Innovation. Why Beneficial Effects of Innovation Highly Depend [PDF]

open access: yesЖурнал институциональных исследований, 2019
Mainstream economics and everyday consciousness tend to declare any change an “innovation”. Innovation thus appears as a black box. It seems to lack a criterion to distinguish a counterproductive change – e.g., a dynamic perceived by agents as over ...

Heavy Quark Radiative Energy Loss in QCD Matter

open access: yes, 2003
Heavy quark medium induced radiative energy loss is derived to all orders in opacity, $(L/\lambda_g)^n$. The analytic expression generalizes the GLV opacity expansion for massless quanta to heavy quarks with mass $M$ in a QCD plasma with a gluon ...

Nanofillers Reinforcing Biopolymer Composites for Sustainable Food Packaging Applications: A State‐of‐the‐Art Review

open access: yesAdvanced Functional Materials, EarlyView.
Biopolymers are sustainable, biodegradable alternatives to petroleum‐based plastics for food packaging. Its adoption is often limited by poor mechanical strength, barrier properties, and improved thermal stability through the incorporation of nanofillers.

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

open access: yesAdvanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Analyzing opacity with contextual faithfulness constraints

open access: yesGlossa, 2020
Phonological opacity is well-studied and there are numerous proposals in the literature which analyze opacity in Optimality-Theoretic grammars. However, many analyses include significant elaborations to the basic architecture of Optimality Theory (Prince

Constraints on the opacity profile of the sun from helioseismic observables and solar neutrino flux measurements

open access: yes, 2010
Motivated by the solar composition problem and by using the recently developed Linear Solar Model approach, we analyze the role of opacity and metals in the sun.
