Molecular gas in low-metallicity starburst galaxies: Scaling relations and the CO-to-H$_2$ conversion factor

open access: yes, 2015
We study the molecular content and the star formation efficiency of 21 Blue Compact Dwarfs (BCDs). We present CO(1-0) and (2-1) observations, further supplemented with additional CO measurements and multiwavelength ancillary data from the literature.

Controlling the Helicity and Handedness of Polyaromatics with Isobenzofuranophane

open access: yesAngewandte Chemie, EarlyView.
Isobenzofuranophanes are introduced as helical synthons that enable late‐stage helicity induction and control in polyaromatics. This remote tethering approach allows precise control over the handedness and pitch of [5]helicenes via the tether length, inducing significant molecular distortion and affecting chiroptical properties.

Atmospheric Waves Driving Variability and Cloud Modulation on a Planetary-mass Object

open access: yesThe Astrophysical Journal
Planetary-mass objects and brown dwarfs at the transition ( T _eff ∼ 1300 K) from relatively red L dwarfs to bluer mid-T dwarfs show enhanced spectrophotometric variability.

Gastrointestinal Issues in CHARGE Syndrome: Prevalence, Patterns, and Constipation‐Related Quality of Life

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Gastrointestinal (GI) symptoms are common in CHARGE syndrome, but their frequency and characteristics remain poorly documented due to the complex nature of CHARGE syndrome. This study aimed to determine the prevalence of GI issues in CHARGE syndrome and their impact on quality of life (QoL).

Management of Cardiovascular Health Issues in Turner Syndrome: Expert Insights and Expanded Recommendations From the 2024 Guideline Development Team

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Turner syndrome (TS) is frequently complicated by congenital heart disease (CHD). While left‐sided lesions such as bicuspid aortic valve (BAV) and coarctation of the aorta are the most common structural heart lesions in TS, other anomalies, such as aortic arch malformations, hypoplastic left heart syndrome (HLHS), persistent left superior vena

Microphysical Prescriptions for Parameterized Water Cloud Formation on Ultra-cool Substellar Objects

open access: yesThe Astrophysical Journal
Water must condense into ice clouds in the coldest brown dwarfs and exoplanets. When they form, these icy clouds change the emergent spectra, temperature structure, and albedo of the substellar atmosphere. The properties of clouds are governed by complex

Astrometric Discovery of GJ 802b: In the Brown Dwarf Oasis?

open access: yes, 2005
The Stellar Planet Survey is an ongoing astrometric search for giant planets and brown dwarfs around a sample of about 30 M-dwarfs. We have discovered several low-mass companions by measuring the motion of our target stars relative to their reference ...

Supporting the Recovery of NDIS Participants With Psychosocial Disability: A Narrative Literature Review

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT This narrative literature review examines key issues surrounding psychosocial disability support in the National Disability Insurance Scheme (NDIS). It highlights the NDIS's neoliberal approach to support, which has underpinned a lack of clarity around the conceptualisation of psychosocial disability and recovery.
