The environmental pollutant 7H-dibenzo(c,g)carbazole (DBC) has been shown to be a potent carcinogen in various mouse tissues, but displays an unusual degree of hepatocarcinogenicity. We have previously reported that in accord with this activity, mouse liver is the target organ for DBC-DNA binding, with total levels being up to 2700 times greater than in extrahepatic tissues after s.c. administr...

In this paper we introduce a novel approach to continual planning and control, called Dynamics Based Control (DBC). The approach is similar in spirit to the Actor-Critic [6] approach to learning and estimation-based differential regulators of classical control theory [12]. However, DBC is not a learning algorithm, nor can it be subsumed within models of standard control theory. We provide a gen...

Synaptic transmission between rods and depolarizing bipolar cells (DBC) was studied by using simultaneous recording techniques in the living retinal slice preparation. Current injection into the rod elicited a sign-inverting, sustained voltage change in the DBC. Voltage "tails" after the termination of a bright flash were observed in dark-adapted rods and DBC but not in cones. These simultaneou...

The Distributed Batch Controller (DBC) supports scientiic batch data processing. The DBC distributes batch jobs to one or more pools of workstations and monitors and controls their execution. The pools themselves may be geographically distributed, and need not be dedicated to processing batch jobs. We describe the use of the DBC in a large scientiic data processing application, namely the gener...

The Fractal Dimension (FD) of an image defines the roughness using a real number which is highly associated with the human perception of surface roughness. It has been applied successfully for many computer vision applications such as texture analysis, segmentation and classification. Several techniques can be found in literature to estimate FD. One such technique is Differential Box Counting (...

Design By Contract (DBC) is a systematic approach to specifying and implementing object-oriented software systems. DBC has been proved to greatly benefit software development. However, Java does not natively support DBC. We have developed a comprehensive solution to bring DBC into Java. The static and dynamic contract verifier is the most crucial part of the solution. We have developed a toolse...

Consider a memoryless degraded broadcast channel (DBC) in which the channel output is a singleletter function of the channel input and the channel noise. As examples, for the Gaussian broadcast channel (BC) this single-letter function is regular Euclidian addition and for the binary-symmetric BC this single-letter function is Galois-Field-two addition. This paper identifies several classes of d...

We present the use of direct bonded copper (DBC) for the straightforward fabrication of high power atom chips. Atom chips using DBC have several benefits: excellent copper/substrate adhesion, high purity, thick (> 100 μm) copper layers, high substrate thermal conductivity, high aspect ratio wires, the potential for rapid (< 8 hr) fabrication, and three dimensional atom chip structures. Two mask...

Black carbon (BC), pyrogenic organic matter generated from the incomplete combustion of biomass, is ubiquitous in the environment. The molecular structures which comprise the BC pool of compounds are defined by their condensed aromatic core structures polysubstituted with O-containing functionalities (e.g., carboxyl groups). Despite the apparent hydrophobicity of BC molecules, a considerable po...
