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 ...

High-Resolution Rotation Curves and Galaxy Mass Models from Things

, 2016
We present rotation curves of 19 galaxies from The H I Nearby Galaxy Survey (THINGS). The high spatial and velocity resolution of THINGS make these the highest quality H I rotation curves available to date for a large sample of nearby galaxies, spanning ...

PROBES. I. A Compendium of Deep Rotation Curves and Matched Multiband Photometry

The Astrophysical Journal Supplement Series, 2022
We present the Photometry and Rotation Curve Observations from Extragalactic Surveys (PROBES) compendium of extended rotation curves for 3163 late-type spirals, with matching homogeneous multiband photometry for 1677 of them.

Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

Meteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

On the Rotation Curve of Disk Galaxies in General Relativity

The Astrophysical Journal, 2022
Abstract Recently, it has been suggested that the phenomenology of flat rotation curves observed at large radii in the equatorial plane of disk galaxies can be explained as a manifestation of general relativity (GR) instead of the effect of dark matter (DM) halos.

Correlation functions of matter from galaxy rotation curves

, 1991
Based on the disk-halo decomposition method introduced by Persic & Salucci, we use 58 spiral rotation curves to measure the galaxy-background correlation function in the range 3-350 kpc (for H0 = 50 km s-1 Mpc-1).

A C‐repeat binding factor–salicylic acid (CBF–SA) module links wound‐induced evaporative cooling to tissue repair in plants

New Phytologist, EarlyView.
A model of the C‐repeat binding factor–salicylic acid (CBF–SA) module in plant wound healing. Summary Repairing damaged tissues is essential for the survival of all organisms. In plants, tissue injury rapidly triggers defense and repair programs. However, the molecular mechanisms linking early injury cues to the later stage of wound repair remain ...

Universal Collapse of Galaxy Rotation Curves from a Logarithmic Structural Variable [PDF]

We analyze galaxy rotation curves using observational data from the SPARC database (Lelli, McGaugh & Schombert, 2016), based exclusively on the measured radial distance r and rotation velocity v, without introducing dynamical models or external ...

Dark matter and galaxy rotation curves [PDF]

, 2017
Cosmological N-body simulations on structure formation in a Λ−CDM scenario point to a mass density distribution of dark matter, in local objects like galaxies, that are in strong tension with recent observations on low surface brightness galaxies ...

Cis–Trans Rotational Isomerism of Formic Acid, Sulfur, and Selenium Analogues and Their Dimers: Chemical Kinetics Under Interstellar Conditions

International Journal of Chemical Kinetics, Volume 58, Issue 12, Page 1136-1145, December 2026.
ABSTRACT We present chemical kinetic rate constants for the cis to trans isomerisation or rotamerization of monomeric seleno‐, thio‐, and formic acids and that of three of their dimeric species, based on variational transition state theory and multidimensional tunneling calculations in the gas‐phase, from 10 K to 300 K. These provide, firstly, reliable
