Rhabdoid papillary meningioma is an uncommon aggressive variant of meningioma which has the potential to metastasize and spread throughout the brain and even out of the cranium. Herein, we present recurrence of the brain tumor in a 26-year-old woman. The patient had history of the surgery for two lesions in the right temporal lobe and the left cerebellopontine angle. Imaging showed three lesion...

We propose a two-phased approach to learn pattern graphs, a powerful pattern language for complex, multivariate temporal data, which is capable of reflecting more aspects of temporal patterns than earlier proposals. The first phase aims at increasing the understandability of the graph by finding common substructures, thereby helping the second phase to specialize the graph learned so far to dis...

A spatial co-orientation pattern refers to objects that frequently occur with the same spatial orientation, e.g. left, right, below, etc., among images. In this paper, we introduce temporal co-orientation pattern mining which is the problem of temporal aspects of spatial co-orientation patterns. A temporal coorientation pattern represents how spatial co-orientation patterns change over time. Te...

1 This work was supported in part by the NSF under grant IRI-93-18773. Abstract The work of Mannila et al. [4] of finding frequent episodes in sequences is extended to finding temporal logic patterns in temporal databases. It is argued that temporal logic provides an appropriate formalism for expressing temporal patterns defined over categorical data. It is also proposed to use Temporal Logic P...

  Introduction: Studies with single photon emission computed tomography (SPECT) have revealed inconsistent changes of regional cerebral blood flow (rCBF) in schizophrenia. Some studies investigated the rCBF and its relationship with psychopathology, positive and negative symptoms in treated patients. However, there is a little information about the pattern of rCBF in ...

1. We recorded from single neurons in the dorsal bank and fundus of the anterior portion of the superior temporal sulcus, an area we term the superior temporal polysensory area (STP). Five macaques were studied under anesthesia ( N20) and immobilization in repeated recording sessions. 2. Almost all of the neurons were visually responsive, and over half responded to more than one sensory modalit...

Pattern users are faced with difficulties in understanding when and how to use the increasing number of available design patterns. This is mainly due to the inherent ambiguity in the existing means (textual and graphical) of describing them. Hence, there is a need to introduce formalism in order to describe them accurately and allow rigorous reasoning about them. The main problem of existing fo...

Previous studies on mining sequential patterns have focused on temporal patterns specified by some form of propositional temporal logic. However, there are some interesting sequential patterns, such as the multi-sequential patterns, whose specification needs a more expressive formalism, the first-order temporal logic. In this paper, we extend a well-known user-controlled tool, based on regular ...
