e d The emphasis on ‘‘open systems’’ in the past few years has led to th evelopment of interface standards in almost all areas of computing: operating . W systems, data communications, graphics, programming languages, and others hile intelligent use of standards can solve many integration problems, the s architecture of applications can significantly affect the degree of success in ystems integ...

Impairments of social cognition are well documented in patients with schizophrenia (SCZ), but the neural basis remains poorly understood. In light of evidence that suggests that the "mirror neuron system" (MNS) and the "mentalizing network" (MENT) are key substrates of intersubjectivity and joint action, it has been suggested that dysfunction of these neural networks may underlie social difficu...

We try to understand the basics of human image processing from a gist recognition per7 spective. Because the gist is only a subset of the image’s information, we think that it is extracted with help of interpretation (feedback). In a perceptual section we list possible mech9 anisms that the interpretation process uses to determine the gist: in addition to the commonly known local-to-global perc...

As a graduate student, I learned to question assumptions. Michael Barbour taught us to challenge the assumption that we could ever really know the "native" condition of California. Marcel Rejmánek taught me to ask, "Is your invasives problem truly growing over time, or does it just look that way because you are doing a better job of measuring it?" These questions underlie my develop­ ment of mo...

The stepwise development of a program using reene-ment requires that the original abstract speciication is realisable, i.e., an implementation exists with identical functionality. In some situations, this may not be desirable or even possible, and an ideal speciication which is only approximated by the nal implementation is used. For these speciications, an informal step, based on the developer...

The Z Z(N) center symmetry plays an important role in the deconfine-ment phase transition of SU(N) Yang-Mills theory at finite temperature. The exceptional group G(2) is the smallest simply connected gauge group with a trivial center. Hence, there is no symmetry reason why the low-and high-temperature regimes in G(2) Yang-Mills theory should be separated by a phase transition. Still, we present...

Leptospirosis is an important occupational disease in New Zealand. The objectives of this study were to determine risk factors for sero-prevalence of leptospiral antibodies in abattoir workers. Sera were collected from 567 abattoir workers and tested by microscopic agglutination for Leptospira interrogans sv. Pomona and Leptospira borgpetersenii sv. Hardjobovis. Association between prevalence a...

Progenitor Leydig cells are derived from stem cells. The proliferation and differentiation of progenitor Leydig cells significantly contributes to Leydig cell number during puberty. However, the regulation of these processes remains unclear. The objective of the present study was to determine whether luteinizing hormone (LH) or androgen contributes to the proliferation and differentiation of pr...

The U.S. Environmental Protection Agency (U.S. EPA) classifies dichloromethane (DCM) as a "probable human carcinogen," based upon its risk assessment conducted in the late 1980s (http://www.epa.gov/iris/subst/0070.htm). Since that time, cancer risk-assessment practices have evolved, leading to improved scientifically based methods for estimating risk and for illuminating as well as reducing res...
