We establish the most general differential equations that are satisfied by the Fourier components of the electromagnetic field diffracted by an arbitrary periodic anisotropic medium. The equations are derived by use of the recently published fast-Fourier-factorization (FFF) method, which ensures fast convergence of the Fourier series of the field. The diffraction by classic isotropic gratings a...

We discuss the classical mechanics on the Grassmannian and the Disc modeled on the ideal L (2,∞). We apply methods of geometric quantization to these systems. Their relation to a flat symplectic space is also discussed. 1 Introduction We will analyze geometric quantization of a classical system which has as its phase space the infinite dimensional Grassmannian or the Disc modeled on the ideal L...

OBJECTIVE To identify the main characteristics of classic migraine, with specific regard to diagnostic criteria for manual therapy practitioners, including chiropractors and osteopaths. METHOD Ten case studies on migraine were reviewed for the symptoms and clinical features. RESULTS The majority of cases reviewed as classic migraines were in reality not correct diagnoses in accordance with ...

This essay critically examines some classic philosophical and legal theories of privacy, organized into four categories: the nonintrusion, seclusion, limitation, and control theories of privacy. Although each theory includes one or more important insights regarding the concept of privacy, I argue that each falls short of providing an adequate account of privacy. I then examine and defend a theo...

Relevance theory is a new way which attempts to show the nature of communication. Based on the classic code-model and Grice’s inferential model, relevance theory holds “every act of ostensive communication communicates the presumption of its own optimal relevance.” With the interpretation of advertising in the frame of relevance theory, this thesis shows advertising communication is ostensive-i...

Using ideas from synthetic topology, a new approach to descriptive set theory is suggested. Synthetic descriptive set theory promises elegant explanations for various phenomena in both classic and effective descriptive set theory. Presently, we mainly focus on developing the ideas in the category of represented spaces.

Many statements from the classic information theory (the theory of Shannon’s entropy) have natural counterparts in the algorithmic information theory (in the framework of Kolmogorov complexity). In this paper we discuss one simple instance of the parallelism between Shannon’s and Kolmogorov’s theories: we prove in the setting of Kolmogorov complexity a version of Wolf’s characterization of admi...

Classic beam theory is frequently used in biomechanics to model the stress behaviour of vertebrate long bones, particularly when creating intraspecific scaling models. Although methodologically straightforward, classic beam theory requires complex irregular bones to be approximated as slender beams, and the errors associated with simplifying complex organic structures to such an extent are unkn...
