Global properties of irregular galaxies
The Astrophysical Journal Supplement Series, 1982 We present optical and radio observations of global properties for a sample of noninteracting irregular galaxies and a few comparison objects. Program galaxies were chosen primarily on the basis of their blue colors and thus may be expected to represent systems with high rates of star formation.

Scalable Computation of Topological Abstractions for Scalar Data
Computer Graphics Forum, EarlyView.Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Nitrogen in irregular galaxies
The Astrophysical Journal, 1990 A study of nitrogen in giant H II regions located within low-abundance irregular galaxies is presented. Both observations and theoretical models are used to examine variations in the abundance of nitrogen relative to oxygen in these galaxies. Analysis of these and previously published observations suggests that the use of low spectral resolution is the

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 ...

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 ...

THE MAGNETIC FIELD OF THE IRREGULAR GALAXY NGC 4214 [PDF]
The Astrophysical Journal, 2011 We examine the magnetic field in NGC 4214, a nearby irregular galaxy, using multi-wavelength radio continuum polarization data from the Very Large Array. We find that the global radio continuum spectrum shows signs that free-free absorption and/or synchrotron losses may be important.

Current Protocols, Volume 6, Issue 9, September 2026.Abstract Phages remain severely under‐sampled, largely due to the limitations of current isolation methods, which are labor‐intensive, low‐throughput, and often restricted to a narrow set of bacterial hosts. To address this gap, we developed a robust and scalable field‐to‐genome workflow that leverages laboratory automation to screen environmental ...

Unveiling the Functional Role of KIF21B in Microglia Inflammatory Response
Glia, Volume 74, Issue 9, September 2026.Microglia express KIF21B in both sexes. KIF21B binds to microglia cytoskeleton; inflammation alters such interaction promoting a phagocytic state in females. In male microglia KIF21B modulates migration. ABSTRACT Microglia are brain immune cells that maintain homeostasis and respond to injury, changing cell morphology to drive inflammation, migration ...

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.
