The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Light-Element Abundance Variations at Low Metallicity: the Globular Cluster NGC 5466

, 2010
We present low-resolution (R~850) spectra for 67 asymptotic giant branch (AGB), horizontal branch and red giant branch (RGB) stars in the low-metallicity globular cluster NGC 5466, taken with the VIRUS-P integral-field spectrograph at the 2.7-m Harlan J.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Evolved Massive Stars at Low Metallicity. VII. The Lower Mass Limit of the Red Supergiant Population in the Large Magellanic Cloud

The Astrophysical Journal
The precise definition of the lower mass limit of red supergiant stars (RSGs) is an open question in astrophysics and does not attract much attention.

Nanoparticles in microdroplets: Recent advances in microfluidic generators for producing functional microbeads

Droplet, EarlyView.
Functional hybrid microbeads with electrical, magnetic, and/or optical responsiveness have emerged as versatile platforms for biotechnology. This review highlights recent advances in microfluidic technologies for producing such microbeads, with a focus on incorporating functional nanoparticles in microdroplet systems.

Clinical periodontal diagnosis

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

Photospheric Helium Abundance in Cool Giants: A Comprehensive Study

The Astrophysical Journal
High-resolution optical spectra of 16 red giants, two early asymptotic giant branch (AGB) stars, and two supergiants, having no/minimal - to super-lithium (Li)-rich abundances, are analyzed to investigate the helium (He)-enhancement. The spectra of eight

Dynamic expression of lamin B1 during adult neurogenesis in the vertebrate brain

Developmental Dynamics, EarlyView.
Abstract Background In mammals, specific brain regions such as the dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles harbor adult neural stem/progenitor cells (ANSPCs) that give rise to new neurons and contribute to structural and functional brain plasticity.

Color–Magnitude Diagram of NGC 205 and Its RR Lyrae Variables

The Astronomical Journal
We present the deepest color–magnitude diagram (CMD) for NGC 205 in the F606W (≈ V ) and F814W (≈ I ) filters. Our archival Hubble Space Telescope/Advanced Camera for Surveys field is centered ∼3 $\mathop{.}\limits^{{\rm{^{\prime} }}}$ 8 northwest of the

Probing the core structure and evolution of red giants using gravity-dominated mixed modes observed with Kepler

, 2012
We report for the first time a parametric fit to the pattern of the \ell = 1 mixed modes in red giants, which is a powerful tool to identify gravity-dominated mixed modes.
