The star formation history of the Sculptor Dwarf Irregular Galaxy [PDF]

open access: yes, 2012
[abridged] We study the resolved stellar populations and derive the SFH of the SDIG, a gas-rich dwarf galaxy member of the NGC7793 subgroup in the Sculptor group. We construct a CMD using archival HST observations and examine its stellar content.

Fine structure of the red clump in Local Group galaxies [PDF]

open access: yes, 1999
Some fine structures can nowadays be identified in the high-quality colour-magnitude diagrams (CMD) of Local Group galaxies. The clump of red giants, for instance, may present a significant colour spread, and extensions to both brighter and fainter ...

Ultra-deep GEMINI near-infrared observations of the bulge globular cluster NGC 6624 [PDF]

open access: yes, 2016
We used ultra-deep $J$ and $K_s$ images secured with the near-infrared GSAOI camera assisted by the multi-conjugate adaptive optics system GeMS at the GEMINI South Telescope in Chile, to obtain a ($K_s$, $J-K_s$) color-magnitude diagram (CMD) for the ...

Hypoglycemia in patients with LAMA2-CMD

open access: yesArquivos de Neuro-Psiquiatria, 2023
Hypoglycemia has been reported in patients with LAMA2-CMD, but the frequency, risk factors, and correlation to genotype/phenotype have not been systematically assessed to date.A retrospective cohort study was performed on 48 patients with LAMA2-CMD. Patients were divided into two groups: a hypoglycemic group, with at least one episode of hypoglycemia ...

Novel evaluation of the two-pion contribution to the nucleon isovector form factors [PDF]

open access: yes, 2005
We calculate the two-pion continuum contribution to the nucleon isovector spectral functions drawing upon the new high statistics measurements of the pion form factor by the CMD-2, KLOE, and SND collaborations.

Maternal psychological distress in primary care and association with child behavioural outcomes at age three [PDF]

open access: yes, 2015
Observational studies indicate children whose mothers have poor mental health are at increased risk of socio-emotional behavioural difficulties, but it is unknown whether these outcomes vary by the mothers’ mental health recognition and treatment status.

An assessment of H‐bridge less grid‐tied multilevel inverter with minimum device count and lesser total standing voltage

open access: yesIET Power Electronics, EarlyView., 2023
An innovative switched‐capacitor‐based inverter is proposed in this article. The suggested converter can produce a five‐level output voltage by utilizing minimal components (single dc source, six switches, and one capacitor). The effectiveness of the suggested inverter is verified by experimental results using hardware in loop OPAL‐RT OP4510.

Traumatic Microhemorrhages Are Not Synonymous With Axonal Injury

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Diffuse axonal injury (DAI) is caused by acceleration‐deceleration forces during trauma that shear white matter tracts. Susceptibility‐weighted MRI (SWI) identifies microbleeds that are considered the radiologic hallmark of DAI and are used in clinical prognostication.

The Effect of Purcell Cavities on the Lifetime of Thermally Activated Delayed Fluorescent Emitters

open access: yesAdvanced Functional Materials, EarlyView.
A pressing challenge to OLED displays and lighting is to balance high efficiency and long operational lifetime in the deep blue spectrum. The Purcell effect can reduce the triplet density and hence the probability for destructive energy‐driven triplet annihilation events that limit the OLED lifetime. Here we study of the Purcell effect on two different
