When designing a mechanism there are several desirable properties to maintain such as incentive compatibility (IC), individual rationality (IR), and budget balance (BB). It is well known [15] that it is impossible for a mechanism to maximize social welfare whilst also being IR, IC, and BB. There have been several attempts to circumvent [15] by trading welfare for BB, e.g., in domains such as do...

The aim of this randomized observational study was to evaluate the effect of measuring the incisor-carina distance by fiberoptic bronchoscopy in guiding the placement of a left-sided double-lumen endobronchial tube. Fifty patients (American Society of Anesthesiologists class I-II) undergoing elective thoracic procedures requiring single-lung ventilation using a left-sided double-lumen endobronc...

In wave theory, the homogeneous Green's function consists of the impulse response to a point source, minus its time-reversal. It can be represented by a closed boundary integral. In many practical situations, the closed boundary integral needs to be approximated by an open boundary integral because the medium of interest is often accessible from one side only. The inherent approximations are ac...
