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...

Surgery schedules are subject to disruptions due to duration uncertainty, patient punctuality, surgery cancellation, surgical emergencies and recovery resource availability. Such disruptions may result in inefficient utilization of medical resources, suboptimal patient care and patient and staff dissatisfaction. To alleviate these issues, we propose a proactive-reactive surgery scheduling metho...

Background: Preoperative hematocrit estimation has been one of the basic routine requirements before an anaesthetic is administered. Non availability of hematocrit result or a value less than 30% often led to cancellation of an elective surgery by the anaesthetist. Objective: The aim of the study was to determine the prevalence of anemia among adult patients presenting for day case surgery in t...

OBJECTIVE To evaluate the results of an outpatient program for major dermatological surgery in patients with a range of skin conditions. METHODS We undertook a retrospective, observational study of patients who underwent scheduled dermatological surgery as outpatients in a public hospital between 2004 and 2007. The most common procedures were excision of basal cell or squamous cell carcinoma ...

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...

OBJECTIVE To analyze data corresponding to patients who underwent dermatological surgery in an operating room. MATERIAL AND METHODS This was a descriptive, retrospective study of operating room activities in the dermatology department of Hospital Universitario de Fuenlabrada in Madrid between January 2005 and December 2010. We analyzed the relative frequency of a range of patient and procedur...

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.
