SelExNet: A Self‐Supervised Physics‐Informed Framework for Multi‐Channel Joint RF and Gradient Waveform Optimization in 2D Spatially Selective Excitation

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To introduce SelExNet: a self‐supervised framework for two‐dimensional spatially selective excitation that jointly optimizes radiofrequency (RF) pulses and gradient waveforms, and extends to multi‐channel transmission MRI. Methods Building on prior RF‐only and joint RF‐gradient optimization approaches, SelExNet couples neural RF and ...

Low-metallicity Nova Explosions: A Site for Weak rp-process Nucleosynthesis

open access: yesThe Astrophysical Journal
Classical novae are common cataclysmic events involving a binary system of a white dwarf and a main-sequence or red giant companion star. In metal-poor environments, these explosions produce ejecta differently from their solar counterparts due to the ...

Lectotypifications and taxonomic changes in the holoparasitic Orobanchaceae

open access: yesNordic Journal of Botany, EarlyView.
Based on further extensive studies of specimens in various herbaria, lectotypes are designated for many taxa of holoparasitic Orobanchaceae. In particular, 47 names in the genera Boschniakia (incl. Xylanche), Cistanche, Orobanche, Phelipanche and Phelypaea are lectotypified.

A Smile From the Past: Exploring a Fixed Bone Dental Bridge From Eighteenth/Nineteenth Century Porto (Portugal)

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This paper presents the first documented case of a fixed bone dental bridge in Portugal. This item was recovered alongside the remains of a young adult individual of indeterminate sex from the 19th century burial site of the 3rd Order of Our Lady of Carmo in Porto, Portugal.

Leveraging Artificial Intelligence (AI) to Strengthen MTSS Within Catholic Schools

open access: yesPsychology in the Schools, EarlyView.
ABSTRACT Many Catholic schools face resource challenges that result in limitations surrounding the implementation of multi‐tiered systems and support (MTSS). Artificial intelligence (AI) offers a potential tool for Catholic schools to strengthen systems of support. This article provides a conceptual analysis regarding opportunities for AI to strengthen

Calcium Excess in Novae: Beyond Nuclear Physics Uncertainties

open access: yesThe Astrophysical Journal
We examine Ca abundances in classical novae from spectroscopic observations spanning 65 yr and investigate whether they are systematically high compared to those predicted by nova models.

Activating Paper Applying Gelatin, Starch and Chitosan Coatings Loaded With O/W Emulsions Encapsulating Rutin, Carvacrol and α‐Tocopherol

open access: yesPackaging Technology and Science, EarlyView.
Emulsion type governed the microstructure and functionality of papers coated with biopolymers matrix loaded with hydrophobic bioactives encapsulated into O/W emulsions. Emulsified systems improved UV–Vis barrier and antioxidant activity, whereas gelatin coatings with conventional or Pickering emulsions provided the greatest mechanical reinforcement ...
