In his search for a unified field theory that could undercut quantum mechanics, Einstein considered five dimensional classical Kaluza-Klein theory. He studied this theory most intensively during the years 1938-1943. One of his primary objectives was finding a non-singular particle solution. In the full theory this search got frustrated and in the x-independent theory Einstein, together with Pau...

Stimulants have been shown to be safe and effective for reduction of the symptoms of attention deficit hyperactivity disorder. Despite much debate, however, there has been little empirical evidence as to whether stimulants affect authenticity and moral agency in children. Singh presents evidence that stimulants do not undercut children's' sense of self and increase their experience of agency. T...

This short paper is intended to demonstrate a crucial omission made by traders in setting the risk-free interest rate, especially times of crisis: instead increasing undercut it en masse on contrary. results incorrect investment and financial decisions, those involving CAPM models, option pricing models portfolio theory.

Energy efficiency improvements “rebound” when economic responses undercut their direct energy savings. I develop an analytic general equilibrium framework that allows improvements in energy efficiency to affect output prices and factor prices. I show that general equilibrium channels typically amplify rebound and make it more likely that improvements in efficiency end up increasing total energy...

A small depression is created in a straight optical fiber taper to form a local probe suitable for studying closely spaced, planar microphotonic devices. The tension of the "dimpled" taper controls the probe-sample interaction length and the level of noise present during coupling measurements. Practical demonstrations with high-Q silicon microcavities include testing a dense array of undercut m...

We demonstrate all-epitaxial InP-based 1.3μm VCSELs with a record-high continuous-wave differential quantum efficiency (57%) for single active region long-wavelength devices. Low-loss optical mode confinement is achieved through a selectively etched undercut tunnel-junction aperture. Single-mode continuous-wave lasing was observed up to 87°C and the room-temperature output power was 1.1mW at a ...

Sculptured surfaces are usually machined to their final shapes by a series of rough and finish passes. After each pass, excess material may be left at some concave or C1 discontinuous areas. Traditionally these undercut areas are “cleaned up” by repeatedly machining the whole surface with progressively smaller cutting tools. We present an algorithm for automatically identifying areas with exces...

269 ABSTRACT: We evaluated eight habitat objectives used by land management agencies within the Interior Columbia Basin to determine if the current riparian management objectives (RMOs) were representative of conditions found at reference sites, had values which differed significantly between reference and managed watersheds, and whether these RMOs could be consistently applied across the study...

PURPOSE The riegel and swing-lock attachments are excellent retainers in terms of secure retention, but the former requires a great volume of abutment tooth reduction and the latter has problems with aesthetics and abrasion. In contrast, the RPI and RPA clasps have been highly appreciated as excellent retainers for abutment tooth protection, but any retentive forces are needed. Thus, the purpos...

Parallel arrays of either Au or Pd nanowires were fabricated on glass substrates via the electrochemical process of lithographically patterned nanowire electrodeposition (LPNE) and then characterized with scanning electron microscopy (SEM) and a series of optical diffraction measurements at 633 nm. Nanowires with widths varying from 25 to 150 nm were electrodeposited onto nanoscale Ni surfaces ...
