In this paper we present a methodology for blind source separation (BSS) based on a coherence function to solve the problem of linear instantaneous mixtures of signals. The proposed methodology consists of minimizing the coherence function using a heuristic algorithm based on the simulating annealing method. Also, we derived an analytical expression of the coherence for the BSS model, in which ...

Surg Radiol Anat 1996;18: 295–302 The location and course of the white matter tracts in the cerebrum are described and shown by means of diagrams in Tailarach space. If you want to understand the location and course of the major and the obscure white matter trac...

Ferlito A, Devaney KO, Rinaldo A, et al. Ear cholesteatoma versus cholesterol granuloma. Ann Otol Rhinol Laryngol 1997;106:79–85 This is an excellent histopathology-based review (no images) that defines and differentiates these two entities. Very interesting information. Authors reiterate that cholesteatoma is a misnomer: it is not a neoplasm (-oma), there are no cholesterol crystals (chole-), ...

Zumkeller M, Behrmann R, Heissler HE, Dietz H. Computed tomographic criteria and survival rate for patients with acute subdural hematoma. Neurosurgery 1996;39: 708–713 Among 174 patients with acute subdural hematomas, hematoma thickness exceeding 18 mm was associated with survival rates that progressively fell below 50%. A 50% survival rate was reached when the midline shift reached 50%, and su...

UNLABELLED There has been no consensus on a standard calculational approach regarding the concept of administered activity in ventilation studies involving inhaled radioisotope gas or radioaerosols. This is caused in part by a lack of knowledge regarding the actual activity that enters the lung space (as opposed to activity introduced into the delivery system) and to the extended administration...

This paper focuses on the class of legal rules that governs intellectual property rights: the antitrust limits imposed on patent settlements. The paper discusses the benefits and costs of settlements and explains why antitrust limits on settlements are needed to prevent abuse of the settlement process. It develops a general rule for evaluating proposed settlements. This paper explores a simple ...
