KID-PPG: Knowledge Informed Deep Learning for Extracting Heart Rate from a Smartwatch

David Atienza Alonso, José Angel Miranda Calero, Jonathan Dan, Christodoulos Kechris

Accurate extraction of heart rate from photoplethysmography (PPG) signals remains challenging due to motion artifacts and signal degradation. Although deep learning methods trained as a data-driven inference problem offer promising solutions, they often un ...

Hybrid polarizing solids for pure hyperpolarized liquids through dissolution dynamic nuclear polarization

David Lyndon Emsley, Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Jonas Milani, Basile Vuichoud, David Benjamin Roger Antoine Gajan

Hyperpolarization of substrates for magnetic resonance spectroscopy (MRS) and imaging (MRI) by dissolution dynamic nuclear polarization (D-DNP) usually involves saturating the ESR transitions of polarizing agents (PAs; e.g., persistent radicals embedded in ...

Stimulation by nicotine of enteric inhibitory nerves and release of vasoactive intestinal peptide in the taenia of the guinea-pig caecum

Pierre Magistretti, Jean-Luc Martin

The stimulation by nicotine of intramural nerves and the role of ATP and vasoactive intestinal peptide (VIP) as inhibitory transmitters were studied in the isolated taenia of the guinea-pig caecum. Nicotine (4-32 microM) caused transient, concentration-dep ...
