DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

Computer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

A Multiwavelength Portrait of the 3C 220.3 Lensed System

The Astrophysical Journal
The 3C 220.3 system is a rare case of a foreground narrow-line radio galaxy (“galaxy A,” z _A = 0.6850) lensing a background submillimeter galaxy ( z _SMG = 2.221).

AstroSat-UVIT observations of a possibly interacting pair of galaxies in HCG 77

Astronomy & Astrophysics
Context. Interactions and mergers possibly enhance the star formation in dwarf galaxies in a group environment. Aims. We aim to study star-forming regions and the spectral energy distribution of two possibly interacting galaxies, PGC 56121 and PGC 56125,

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 ...

A Multiwavelength Approach to Constraining the Merger Properties of ACT-CL J0034.4+0225

The Astrophysical Journal
ACT-CL J0034.4+0225 is a previously unrecognized merging galaxy cluster at z = 0.38588 ± 0.00068. Our primary evidence is provided by a 21 ks Chandra image that shows two surface brightness peaks separated by ∼49″ (259 kpc) surrounded by an extended ...

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 ...

Super-size Me: The Big Multi-AGN Catalog (The Big MAC) Data Release 1: The Source Catalog

The Astrophysical Journal Supplement Series
Galaxy mergers represent the most transformative and dramatic avenue for galaxy and supermassive black hole (SMBH) evolution. Multiple active galactic nuclei (multi-AGNs) are expected to ignite, grow, and evolve alongside the host galaxies, and these ...

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 ...

Inhibition of Ornithine Decarboxylase 1 Mitigates Denervation‐Induced Muscle Atrophy by Suppressing Proteolysis and Preserving Muscle Stem Cell Homeostasis

Cell Proliferation, EarlyView.
Polyamine metabolism is innervation responsive and involved in denervation‐induced muscle atrophy. Inhibition of polyamine metabolism attenuates muscle atrophy by restraining proteolysis and preserving MuSCs homeostasis. Denervation‐induced activation of FAP‐derived FGF7 drives premature MuSCs activation, while DFMO suppresses this paracrine cue to ...

Behavioural Determinants of Post‐Brushing Dental Plaque Levels: A Video‐Based Analysis

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Objectives Toothbrushing remains the most widely practiced method for dental plaque removal. However, evidence‐based guidance on optimal brushing method, duration, toothbrush bristle wear, and dentifrice quantity is still insufficient. This study aimed to identify behavioural factors associated with post‐brushing dental plaque levels using ...
