English) joint cancellation model guaranteed A. de Cheveigné, H. Kawahara, "Multiple pitches", last revised: 8 July 1998 2 Number of pages (including figures): Number of Figures: Number of Tables: The pitch of a periodic sound is strongly correlated with its period. To perceive the multiple pitches evoked by several simultaneous sounds, the auditory system must estimate their periods. This pape...

In the field of acoustic echo cancellation, it is well known that the amount of cancellation attainable in real-world systems is limited. Euphemistically this limitation has been referred to in the acoustic echo cancellation community as the “20 dB rule” [1]. This rule reflects the observation that, typically, one can obtain only about 20 to 30 dB of acoustic echo cancellation in actual physica...

introduction: coverage of bone grafts is very important in reconstructive surgery. in edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for upp...

the coverage of soft- tissue defects of the hand specially volar side needs special consideration. although certain local flaps have been described and used for resurfacing the palm, extensive injury requires distant or free flaps for coverage. abdominal pedicle flap has been traditionally used for extensive hand injuries, however there is no doubt that one of the ideal tissues for resurfacing ...

Since its first appearance in Wuhan at the end of 2019, SARS-CoV-2 pandemic has brought serious repercussions worldwide, Spain being among most affected countries. This health crisis resulted cancellation surgeries pertaining to both malignant and benign pathologies, including bariatric metabolic surgery. Patients with morbid obesity, besides their delay surgical interventions, are high risk co...

A meadow is a zero totalised field (0 = 0), and a cancellation meadow is a meadow without proper zero divisors. In this paper we consider differential meadows, i.e., meadows equipped with differentiation operators. We give an equational axiomatization of these operators and thus obtain a finite basis for differential cancellation meadows. Using the Zariski topology we prove the existence of a d...

For even dimensional manifolds, we prove some twisted anomaly cancellation formulas which generalize some well-known cancellation formulas. For odd dimensional manifolds, we obtain some modularly invariant characteristic forms by the Chern-Simons transgression and we also get some twisted anomaly cancellation formulas. Subj.

We give a direct proof of a cancellation formula raised by Han and Zhang (2004) on the level of differential forms. We also obtain more cancellation formulas for even dimensional Riemannian manifolds with a complex line bundle involved. Relations among these cancellation formulas are discussed.

In this paper, we present the results of the Acoustic Event Detection (AED) and Classification (AEC) evaluations carried out in February 2006 by the three participant partners from the CHIL project. The primary evaluation task was AED of the testing portions of the isolated sound databases and seminar recordings produced in CHIL. Additionally, a secondary AEC evaluation task was designed using ...
