This paper explores the use of Spherical Harmonics to represent the reflectance function of a 3D surface with known geometry. It is shown that reflectance can be conceived of as a convolution in the angular domain. Spherical Harmonics are used to define a frequency domain in which convolution in the angular domain is equivalent to multiplication in the spherical harmonic frequency domain. This ...

pound responsible for the pungent character of various hot peppers (Capsicum), and it is famous for its pungent taste, burning sensation, and various effects on body temperature and gastric acid secretion. These features of capsaicin are considered to be generated by capsaicin associating with the capsaicin receptor, or the transient receptor potential cation channel of vanilloid type 1 (TRPV1)...

The homology of Pseudomonas cytochrome c-551 with eukaryotic cytochromes c is examined with a computer-based procedure devised to determine whether similarities exist between these proteins. One method is given by which the more recently evolved cytochromes c might have arisen from the Pseudomonas protein. This procedure involves only common genetic phenomena and accounts for most of the struct...

Markov Decision Process (MDP) has been used as a theoretical framework to solve AI problems for many decades. However, thus far most of the results cannot be effectively applied to most real world domains, which have large state spaces, indeterminant (fuzzy) goal states, incorrect guiding functions, and partial observability in general. This paper explores abstractions, approximations that occu...

The societies developed in the Nordic countries attract widespread international attention. These societies are among the richest in the world, they are among the most equal in the world, and their inhabitants seem to be among the happiest in the world. These merits and the fact that these countries are secularised, have (post)modern family structures, and always have been (small) open economie...

Microcolonial structures have been harvested from desert rock samples for cultivation and ultrastructural examination. The results indicate that these microcolonial structures are fungi previously unrecognized as inhabitants of desert rocks.

The determination of external dose to teeth of inhabitants of settlements near the Semipalatinsk Nuclear Test Site (SNTS) was conducted using the EPR dosimetry technique to assess radiation doses associated with exposure to radioactive fallout from the test site. In this study, tooth doses have been reconstructed for 103 persons with all studied teeth having been formed before the first nuclear...
