Monte Carlo-based Noise Compensation in Coil Intensity Corrected Endorectal MRI [PDF]
, 2015 Background: Prostate cancer is one of the most common forms of cancer found in males making early diagnosis important. Magnetic resonance imaging (MRI) has been useful in visualizing and localizing tumor candidates and with the use of endorectal coils ...

Group Iterative Spectrum Thresholding for Super-Resolution Sparse Spectral Selection [PDF]
, 2013 Recently, sparsity-based algorithms are proposed for super-resolution spectrum estimation. However, to achieve adequately high resolution in real-world signal analysis, the dictionary atoms have to be close to each other in frequency, thereby resulting ...

Analyzing Peer Selection Policies for BitTorrent Multimedia On-Demand Streaming Systems in Internet [PDF]
, 2014 The adaptation of the BitTorrent protocol to multimedia on-demand streaming systems essentially lies on the modification of its two core algorithms, namely the piece and the peer selection policies, respectively. Much more attention has though been given

La problématique foncière de la compensation écologique [PDF]
Sciences, Eaux & Territoires, 2020 La disponibilité du foncier est l’un des verrous opérationnels identifiés par les acteurs pour la mise en œuvre des mesures compensatoires. Dans le cadre de l’application de la séquence Éviter-Réduire-Compenser, cette mise en œuvre se heurte à la double ...

On the origin of X-ray spectra in luminous blazars [PDF]
, 2013 Gamma-ray luminosities of some quasar-associated blazars imply jet powers reaching values comparable to the accretion power even if assuming very strong Doppler boosting and very high efficiency of gamma-ray production.
