Day surgery is increasing, and safe and effective logistics are Background: sought. One part of the in-theatre logistics commonly discussed is whether surgical scrub and sterile covering should be done before or after induction of anaesthesia. The aim of the present study was to compare the impact of surgical scrub and sterile covering before after the induction of anaesthesia vs. in male pat...

Highly available storage uses replication and other redundant storage to recover from a component failure. If parity data calculated from an erasure correcting code is not updated or becomes otherwise corrupted, recovery from a failure does not recover the correct data but mostly garbled data. This paper presents an algebraic signature scheme that can detect parity discrepancies for parity calc...

Interactive realtime tools for education were developed making use of Matlab GUI functions. They are a) a realtime spectrogram with narrowband, wideband and perceptual frequency resolution axes, b) a realtime spectrum monitoring followed by an interactive spectrogram display with sound playback of a rectangular time-frequency region and scrubbing inspection, c) realtime vocal tract shape displa...

The Leap Motion opens new possibilities for mapping the various degrees of motion of the human hand with musical expression. The Leap Motion is a computer peripheral released in mid 2013 that uses IR cameras to track hand and finger location with unprecedented accuracy. In this paper, we explore implementations of the device in sound synthesis and effects control. The device is interfaced with ...

We examined changes in the diversity of herbaceous plant species at colony ( ) sites of the plains vizcacha Lagostomus maximus following local extinctions of this species in semi-arid scrub of central Argentina. These large rodents live in social groups, share a communal burrow system, and forage in a common home range around the burrow system. Through intense herbivory, vizcachas create large ...
