Survey on Visualization of Information Diffusion over Networks

Computer Graphics Forum, EarlyView.
Abstract Information Diffusion (ID) describes how a value (e.g., a pathogen, a rumor, a packet) spreads through an underlying “medium” network of elements (e.g., a social or computer network). Understanding the information diffusion process is essential to predicting trends, controlling misinformation, and enhancing decision‐making as well as ...

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]

, 2005
Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Concatenated Irregular Variable Length Coding and Irregular Unity Rate Coding [PDF]

, 2009
In this contribution we propose the novel serial concatenation of Irregular Variable Length Coding (IrVLC) and Irregular Unity Rate Coding (IrURC), where we matched the corresponding EXtrinsic Information Transfer (EXIT) functions to each other.

Modeling Solitonic Cores, Stabilization of Bar, and Suppression of Bar Dissolution in DDO 168 via GPP Formalism: A Detailed Analysis of Bose–Einstein Condensate/Fuzzy Dark Matter Halo Structure and Bar Dynamics in the Dwarf Galaxy DDO 168

The Astrophysical Journal
The cusp–core problem remains a challenge to the ΛCDM model, since dwarf galaxies often exhibit flat central density cores rather than the steep cusps ( ρ  ∝  r ^−1 ) predicted by collisionless N -body simulations.

FaceIt: Real‐Time On‐Device Identity‐Preserving Portrait Animation

Computer Graphics Forum, EarlyView.
A real‐time, on‐device algorithm for animating a single portrait image using detailed facial expressions and motions from a driving video achieving visual quality that can outperform even techniques with significantly higher computational overhead. Abstract Recently, significant progress has been made in generating expressive and temporally coherent ...

Ram-pressure signatures in the dwarf irregular galaxy Sextans B revealed by deep MeerKAT H I observations

Astronomy & Astrophysics
Context. The impact of extremely low-density environments such as the diffuse intergalactic medium (IGM) on the neutral gas distribution of dwarf galaxies remains poorly explored observationally. Aims.

Delayed Massive-star Mechanical Feedback at Low Metallicity

The Astrophysical Journal, 2023
The classical model of massive-star mechanical feedback is based on effects at solar metallicity ( Z _⊙ ), yet feedback parameters are very different at low metallicity.

Magnetic Fields in Irregular Galaxies [PDF]

Highlights of Astronomy, 2002
AbstractRadio data of large irregular galaxies reveal some extended synchrotron emission with a substantial degree of polarization. In the case of NGC 4449 strong galaxy-scale regular magnetic fields were found, in spite of the lack of ordered rotation required for the conventional dynamo action.

Gastroschisis‐Like Defect in a Crossbred Bovine Calf: Anatomical, Clinical and Surgical Perspectives

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
A gastroschisis‐like defect was observed in a one‐day‐old, crossbred bovine calf with evisceration of the pyloric abomasum and small intestine, likely resulting from prenatal rupture of an omphalocele. The calf presented with lethargy, hypothermia and metabolic derangements, along with elevated renal biomarkers.
