Study of digital palmar and plantar arteries of horses and mules by B-mode and Doppler ultrasonography
ABSTRACT The present study aimed to evaluate and compare the palmar and plantar digital arteries of 10 horses and 10 mules through B-mode and spectral Doppler ultrasound. Likewise, compare the plantar arteries of the pelvic limbs with the palmar arteries of the thoracic limbs, in addition to verifying the differences of the digital arteries in the contralateral limbs (right and left) in horses and mules using B-mode and spectral Doppler ultrasonography. The evaluated parameters were the diameter and the intima-media thickness (IMT), resistivity index (RI), pulsatility index (PI), peak of systolic velocity (pSV), final diastolic velocity (fDV) and mean velocity (MV) of the lateral and medial palmar and plantar arteries digital in healthy horses and mules. The horses presented higher diameters values, IMT, pSV, fDV and MV in comparison to the mules. The variables RI and PI also presented differences between horses and mules. Also, both species showed higher values in the variables of B-mode and Doppler ultrasonography in the thoracic limbs. Differences were also detected in the comparison between the limb sides (right and left) in the two modalities. The B-Mode and spectral Doppler ultrasound techniques are viable tools to identify differences in the palmar and plantar digital arteries in healthy horses and mules, highlight the differences between the thoracic and pelvic limbs and their respective sides (right and left) as well

Neutrino oscillation studies with IceCube-DeepCore
AbstractIceCube, a gigaton-scale neutrino detector located at the South Pole, was primarily designed to search for astrophysical neutrinos with energies of PeV and higher. This goal has been achieved with the detection of the highest energy neutrinos to date. At the other end of the energy spectrum, the DeepCore extension lowers the energy threshold of the detector to approximately 10 GeV and opens the door for oscillation studies using atmospheric neutrinos. An analysis of the disappearance of these neutrinos has been completed, with the results produced being complementary with dedicated oscillation experiments. Following a review of the detector principle and performance, the method used to make these calculations, as well as the results, is detailed. Finally, the future prospects of IceCube-DeepCore and the next generation of neutrino experiments at the South Pole (IceCube-Gen2, specifically the PINGU sub-detector) are briefly discussed
