T he article by Velakoulis et al 1 reported the important finding of hippocampal volume reduction in first-episode schizophrenia and interpreted it as evidence in support of a neurodevelopmental model of this disorder. The authors stated that " no [pre-vious] studies have examined the specificity of this finding to first-episode schizophrenia, compared with first-episode affective psychosis. " ...

Among the family of the local patterns, episodes are commonly used when mining a single or multiple sequences of discrete events. An episode reflects a qualitative relation is-followed-by over event types, and the refinement of episodes to incorporate quantitative temporal information is still an on going research, with many application opportunities. In this paper, focusing on serial episodes,...

The documentation of a care episode consists of clinical notes concerning patient care, concluded with a discharge summary. Care episodes are stored electronically and used throughout the health care sector by patients, administrators and professionals from different areas, primarily for clinical purposes, but also for secondary purposes such as decision support and research. A common use case ...

We take a retrospective look at Hungary’s experiment with a particularly draconian bankruptcy law. For an eighteen-month period in 1992–93, the Hungarian bankruptcy code contained an unusual automatic trigger that required the managers of firms that held overdue debts of any size to any creditor to initiate reorganisation or liquidation proceedings to avoid prosecution under the civil code. We ...

Masquerade detection is one of major concerns of system security research due to two main reasons. Such an attack cannot be detected at the time of access and any detection technique relies on user’s signature and even a legitimate user is likely to deviate from its usual usage pattern. In the recent years, there have been several proposals to efficiently detect masquerader while keeping the fa...

We describe the design of Episode, TM a highly portable POSIX-compliant le system. Episode is designed to utilize the disk bandwidth e ciently, and to scale well with improvements in disk capacity and speed. It utilizes logging of meta-data to obtain good performance, and to restart quickly after a crash. Episode uses a layered architecture and a generalization of les called containers to imple...

Fractal dimension of the electroencephalographic (EEG) signal has been argued to reflect the complexity of the underlying brain processes. To this date, conventional studies of EEG in mood disorders have not been able to distinguish between patients and normal individuals. Here we show that, compared to normal subjects, EEG fractal dimension is significantly augmented in the manic episode of bi...
