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

open access: yesInternational 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 ...

Early Type Galaxies And Reliable Galaxy Cluster Selection [PDF]

open access: yes, 2010
In an era of precision cosmology, clusters of galaxies are the natural consequences under the hierarchical scenario, within which clusters directly encapsulate the history of structure formation.

Modular training resources for bioimage analysis

open access: yesJournal of Microscopy, EarlyView.
Abstract Modern microscopy enables us to measure structural and dynamical properties of many biological processes and is therefore an indispensable research tool. However, the amount and complexity of the produced imaging data is steadily increasing.

Galaxy Evolution in Groups and Clusters [PDF]

open access: yes, 2004
In this thesis, we investigate the extent to which galaxy evolution is driven by processes common to the group and cluster environments. A bimodality of galaxy properties such as star formation, strongly dependent upon the local overdensity of galaxies ...

Encounters between M33 and Present-day M31 Satellites Hint at a Previous Group Accretion

open access: yesThe Astrophysical Journal
This work investigates whether two known Andromeda (M31) satellites, Pisces (LGS 3) and Andromeda XVI (And XVI), have interacted with M33, M31’s most massive satellite.

Impact of the invasive diatom species Cymbella janischii on riverine microbial biofilm communities and a potential role of bacterially produced zeatin

open access: yesJournal of Phycology, EarlyView.
Abstract The diatom Cymbella janischii is an invasive species in Japan, causing nuisance blooms by forming thick mats in rivers. To date, there are no documented studies on the microbiome associations in C. janischii mats or the processes that drive bloom formation.

Scylla. II. The Spatially Resolved Star Formation History of the Large Magellanic Cloud Reveals an Inverted Radial Age Gradient

open access: yesThe Astrophysical Journal
The proximity of the Magellanic Clouds provides the opportunity to study interacting dwarf galaxies near a massive host, and spatial trends in their stellar population properties in particular, with a unique level of detail.

Raman analysis of organic refractory materials after energetic processing: Evidence for amorphous carbon on TNOs and comets

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Amorphous carbon (αC) is found in various extraterrestrial particles, including those thought to originate from the outer Solar System. αC can form through two main processes involving C‐rich materials: exposure to energetic charged particles and thermal processing.
