WHEN a middle-aged person is presented for examination because of symptoms of developing dementia, the physician is faced with an interesting, and often an exacting, problem in differential diagnosis. It is proposed to discuss the causes of progressive dementia in such persons and at the same time to make observations from the clinical and pathological viewpoints concerning the individuality of...

The different forms of scleroderma and the pseudosclerodermas, which clinically partially imitate scleroderma, are rare. Due to the large variety and variability of the clinical course, particularly at the onset of disease, diagnosis may be difficult. For differential diagnosis, the presence of Raynaud phenomenon, antinuclear antibodies and the distribution of sclerosis play essential roles. Be...

The conceptualization of a distinct construct known as statistics anxiety has led to the development of numerous rating scales, including the Statistical Anxiety Rating Scale (STARS), designed to assess levels of statistics anxiety. In the current study, the STARS was administered to a sample of 423 undergraduate and graduate students from a midsized, western United States university. The Rasch...

CONTEXT There are a variety of differential diagnoses for an abnormal mass arising from the pancreas of which isolated pancreatic or peripancreatic tuberculosis is an extremely rare diagnosis with a variety of elusive presentations. CASE REPORT We report such a case which masqueraded as malignancy in 43-year-old man presenting with jaundice, weight loss and new onset diabetes. CONCLUSIONS T...

This paper has described some of the interventions developed at the Ackerman Brief Therapy Project in treating the families of symptomatic children. The interventions are based upon a differential diagnosis of the family system and upon an evaluation of that system's resistance to change. They are classified as compliance-based or defiance-based, depending upon the family's degree of anxiety, m...

Geometric reduction methods for differential-algebraic equations (DAEs) aim at an iterative reduction of the problem to an explicit ODE on a lower-dimensional submanifold of the so-called semistate space. This approach usually relies on certain algebraic (typically constant-rank) conditions holding at every reduction step. When these conditions are met the DAE is called regular. We discuss in t...

Created in 1994, Differential Evolution (DE) is relatively new but already has been proven to perform well for optimisation in static environments. But with many realworld optimisation problems having non-static environments, how well can DE perform in these situations? What changes can be done to allow DE to perform better in dynamic environments?

1 Cluster reduction of YDE The elastic and rearrangement processes in the four-particle system with two clusters in the initial and final states can be treated adequately on the base of Yakubovsky differential equations (YDE) [1], [2], [3]

Psychotic features can be present in both narcolepsy and psychosis, which can result in challenges in diagnosis and management. The prevalence of both conditions is low and the reports in young people are scarce. Our report illustrates the relevance of a thorough differential diagnosis as well as the need to explore treatment avenues based on the evidence available for both narcolepsy and psych...
