Canonical quantization has created many valid quantizations that require infinite-line coordinate variables. However, the half-harmonic oscillator, which is limited to the positive coordinate half, cannot receive a valid canonical quantization because of the reduced coordinate space. Instead, affine quantization, which is a new quantization procedure, has been deliberately designed to handle the quantization of problems with reduced coordinate spaces.

Macrophages, which present a very heterogeneous population of cells, play a key role in the maintenance of normal tissue homeostasis, but functional alterations in the resident macrophage pool as well as newly recruited monocyte-derived macrophages are important drivers in the development of low-grade inflammation. While metabolic dysfunction, insulin resistance and tissue damage may trigger or advance pro-inflammatory responses in macrophages, the inflammation itself contributes to the development of insulin resistance and the resulting hyperinsulinemia.

The classical world of p&q, as it is currently understood, is truly disconnected from the quantum world, as it is currently understood. The process of quantization, for which there are several procedures, aims to promote a classical issue into a related quantum issue.

The current study addressed the question of how palmitate might interact with insulin or PGE to induce the formation of the chemotactic pro-inflammatory cytokine interleukin-8 (IL-8). Human THP-1 cells were differentiated into macrophages.

Macrophages produce a range of interleukins as well as prostaglandin E (PGE). To cope with insulin resistance, hyperinsulinemia develops.

We construct a very general family of characteristic functions describing random matrix ensembles (RME) having a global unitary invariance, and containing an arbitrary, one-variable probability measure, which we characterize by a "spread function." Various choices of the spread function lead to a variety of possible generalized RMEs, which show deviations from the well-known Gaussian RME originally proposed by Wigner. We obtain the correlation functions of such generalized ensembles exactly and show examples of how particular choices of the spread function can describe ensembles with arbitrary eigenvalue densities as well as critical ensembles with multifractality.

Wave equations govern the propagation of acoustical or optical fields in diverse physical settings of interest to oceanographers, geologists, atmospheric scientists, among others. For wavelengths much smaller than all other length scales in the system the wave equation solution is generally expressed as a superposition of waveforms, each of which is determined by properties of the rays of geometrical acoustics or optics. Typically such solutions are accurate except in the vicinity of one or another caustic surface such as those defined as a surface across which a jump in the number of rays tracing through each point occurs.

Perturbations of quantum systems ranging from oscillators to fields can be either continuous or discontinuous functions of the coupling. Even nonrenormalizable fields may now find a natural interpretation.
