In this article I intend to show that certain aspects of A.N. Whitehead’s philosophy of organism and especially his epochal theory of time, as mainly exposed in his well-known work Process and Reality, can serve in clarify the underlying assumptions that shape nonstandard mathematical theories as such and also as metatheories of quantum mechanics. Concerning the latter issue, I point to an alre...

We obtained 3.6È20 km photometry of 38 bright [IRAS km)[ 0.7 Jy] main-sequence stars with Fl(12 the Infrared Space Observatory (ISO). Observations were conducted with the ISOPHOT instrument, in the single-pointing photometry mode, through Ðlters at 3.6, 11.5, and 20.0 km. We searched for excess (Vega-type) emission from dust at temperatures K, located at D1È60 AU from the stars. We thus Z100 sa...

The Japanese approach to manage ment has been analyzed in a number of books and articles, including the best-seller Theory Z by William Ouchi (1981), subtitled "How American Business Can Meet the Japa nese Challenge." Ouchi advances The ory Z as a management style that not only yields greater productivity and prof itability, but also higher degrees of worker satisfaction, company loyalty, and p...

A 77-year-old woman with no previous medical hist ory presented with an 18-month history of an enlarging painless scalp nodule, intermittent fevers, fatigue, and 2-kg unintentional weight loss. The patient reported progressive enlargement and ulceration of the skin lesion despite 2 injections of intralesional triamcinolone. Her physical examination was notable for a 10-cm ulcerating occipital s...

We present a new method for estimating the expected return of a POMDP from experi­ ence. The estimator does not assume any knowledge of the POMDP, can estimate the returns for finite state controllers, allows ex­ perience to be gathered from arbitrary se­ quences of policies, and estimates the return for any new policy. We motivate the estima­ tor from function-approximation and impor­ tance sa...

| This paper gives a brief overview on statistical classiication of time series using Hidden Markov Models. To overcome some limitations and assumptions made in the Hidden Markov Model framework two successful hybrid extensions using Neural Networks are presented. At rst, a short description of traditional stochastic-based Hidden Markov Model classiiers with diierent kinds of emission probabili...

The combination of empiric screening and screening guided by the metabolite antagonist the ory has provided agents which temporarily inhibit certain types of animal and human cancer (8). Studies on the mechanism of action of these agents have suggested areas where exploitable biochemi cal differences between normal and neoplastic cells may exist (12). The objective of the work de scribed herein...

The concept of conformal field theory provides a general classification of statistical systems on two-dimensional geometries at the point of a continuous phase transition. Considering the finite-size scaling of certain special observables, one thus obtains not only the critical exponents but even the corresponding amplitudes of the divergences analytically. A first numerical analysis brought up...

Universality in unitary invariant random matrix ensembles with complex matrix elements is considered. We treat two general ensembles which have a determinant factor in the weight. These ensembles are relevant, e.g., for spectra of the Dirac operator in QCD. In addition to the well established universality with respect to the choice of potential, we prove that microscopic spectral correlators ar...
