Intracranial meningioma is a rare tumour in children. In Cushing and Eisenhardt's book (1938) on meningiomas, six occurred in the pre-adolescent age group. A review of the literature found six patients to be under 2 years of age with only one survival (Stern, 1937; Bailey, Buchanan, and Bucy, 1939; Grant, 1947; Cuneo and Rand, 1952). The present report concerns a case of giant meningioma succes...

Abshclct-We consider a class of stochastic hear systems that are subject to jumps of unknown magnitudes in the state variables ornoling at nnknown times. This model can be nsed when considering such problem as estimation for systems subject to possible component fai lures and the tracking of vehicles capable of abrupt maneuvers Using Kalmao-Bucy filtering and generalized likelihood ratio techni...

We propose a novel approximate inference approach for continuous time stochastic dynamical systems observed in both discrete and continuous time with noise. Our expectation-propagation approach generalises the classical Kalman-Bucy smoothing procedure to non-Gaussian observations, enabling continuous-time inference in a variety of models, including spiking neuronal models (state-space models wi...

Bizarre behaviour disturbances in four patients occurring during incomplete recovery from herpes simplex encephalitis are described. Some aspects of their behaviour were similar to that originally described by Klüver and Bucy in monkeys following bilateral temporal lobectomy. Previous reports of behavioural disturbances in man after herpes simplex encephalitis are reviewed and attention drawn t...

This paper surveys some results in stochastic differential delay equations beginning with ”On stationary solutions of a stochastic differential equations” by K. Ito and M. Nisio, 1964, and also some results in stochastic stability beginning with the ”Stability of positive supermartingales” by R. Bucy, 1964. The problems discussed in this survey are the existence and uniqueness of solutions of s...

introduction: the accuracy of analyzing functional mri (fmri) data is usually decreases in the presence of noise and artifact sources. a common solution in for analyzing fmri data having high noise is to use suitable preprocessing methods with the aim of data denoising. some effects of preprocessing methods on the parametric methods such as general linear model (glm) have previously been evalua...

here, we propose an add-drop and a channel drop filter based on two-dimensional photonic crystal all circular ring resonators. these structures are made of a square lattice of silicon rods with the refractive index n1=3.464 surrounded by air (with refractive index n2=1). the broadest photonic band gap occurs at the filling ratio of r/a = 0.17. two linear defect w1 waveguides couple to the ring....

The Kluver-Bucy syndrome (KBS) is a neurobehavioral syndrome and can be seen in association with a variety of neurological disorders. Case records of 6 patients with KBS seen during a period of 5 years in a university hospital were reviewed. During the study period 6 patients with KBS, aged between 4 and 14 years, were seen. Hyperorality, hypersexuality, and abnormal behavior were the most comm...

‎in this paper‎, ‎the notion of the radical of a filter in‎ ‎residuated lattices is defined and several characterizations of‎ ‎the radical of a filter are given‎. ‎we show that if f is a‎ ‎positive implicative filter (or obstinate filter)‎, ‎then‎ ‎rad(f)=f‎. ‎we proved the extension theorem for radical of filters in residuated lattices‎. ‎also‎, ‎we study the radical‎ ‎of filters in linearly o...
