Digital radio links with bandlimited pulses exhibit a severe performance degradation when the transmitter high power amplifier operates near saturation. To cope with the increase of nonlinear intersymbol interference due to the amplifier nonlinearities, a discrete-time Volterra system can be used to process the transmitted data. We present an efficient technique for implementing adaptive data p...

The unilateral involvement of all or nearly all of the cranial nerves, associated with various conditions, was first described by Garcin in 1926. Different conditions such as tumors or inflammations are known to be causes of this syndrome. The primary carcinoma of the middle ear is one of causes of the syndrome of Garcin. In Japan, we have had no report of this syndrome caused by the tumors of ...

UNLABELLED BACKGROUND Gradenigo's syndrome is a rare disease, which is characterized by the triad of the following conditions: suppurative otitis media, pain in the distribution of the first and the second division of trigeminal nerve, and abducens nerve palsy. The full triad may often not be present, but can develop if the condition is not treated correctly. CASE PRESENTATION We report a ...

Plasma cell tumors of the skull base are rare in neurosurgical practice. True solitary osseous plasmacytoma of the skull base without development of multiple myeloma is extremely rare. We report a case of typical Gradenigo's syndrome, including left abducens nerve palsy, left facial pain and paresthesia in V1 and V2 distribution of trigeminal nerve caused by solitary osseous plasmacytoma of the...

BACKGROUND Gradenigo's syndrome includes the triad of suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve. Gradenigo's syndrome is rare, and the diagnosis is easily overlooked. This case is the first to report Gradenigo's syndrome presenting with meningitis on a background of chronic suppurative o...

Information is continuing to grow exponentially and the increasing utilization of electronic and optical publishing technologies is making available large machine-readable document collections. There is a strong need for sophisticated and innovative retrieval systems which can provide satisfactory access to such amounts of stored information. Information Retrieval (IR) has been developing from ...

This paper is limited to the consideration of acquired ocular palsies attributed to involvement of the cranial nerve pathways, i.e. lower motor neurone lesions. It is not concerned with supranuclear problems, retraction syndromes, myasthenia, dysthyroid eye disease, or blow-out fractures. The words palsy, paresis, and paralysis tend to be used interchangeably, but usually paresis means a mild a...

s 107 mean age of 19 years (range 6–50). The mean follow-up was 39 months (range 7–120 months). The vast majority had clear resection margins. Histological response was category 1 in 27% of the patients, and category 2 in 73%. Clinical features, treatment, and prognosis were analysed. Survival rates were examined using Kaplan–Meier Analysis. Results: The average interval between the first resec...

This work addresses the problem of distributed multi-agent localization in presence of heterogeneous measurements and wireless communication. The proposed algorithm integrates low precision global sensors, like GPS and compasses, with more precise relative position (i.e., range plus bearing) sensors. Global sensors are used to reconstruct the absolute position and orientation, while relative se...
