This review focuses on the process of enamel maturation, a series of events associated with slow, progressive growth in the width and thickness of apatitic crystals. This developmental step causes gradual physical hardening and transformation of soft, newly formed enamel into one of the most durable mineralized tissues produced biologically. Enamel is the secretory product of specialized epithe...

Two advanced processes have been developed for fabricating ultra thick and ultra high aspect ratio (HAR) microstructures. One is the SU-8 based deep x-ray lithography (SU-8 based DXRL) process which uses the normal deep x-ray beam to expose the negative SU-8 resist. Another one is wave length shifter(WLS) based Ultra deep x-ray lithography (WLS-UDXRL) process which uses special ultra deep x-ray...

1.1 Fix a variety X over C. The Riemann-Hilbert correspondence identifies the category of perverse sheaves on X(C) with the (abelian) category of regular holonomic D-modules on X. This is a remarkable and deep theorem in the theory of linear partial differential equations. In this note we will investigate this correspondence in simple examples, exploring the topological and algebraic sides as w...

OBJECTIVE This prospective study evaluated the ability of indirect 16-row multidetector CT venography, in comparison with Doppler sonography, to detect deep vein thrombosis after total hip or knee replacement. MATERIALS AND METHODS Sixty-two patients had undergone orthopedic replacement surgery on a total of 30 hip joints and 54 knee joints. The CT venography (scan delay time: 180 seconds; sl...

There is a mismatch between meta and object levels in many calculi, like the sequent calculus and natural deduction. The mismatch has undesirable proof theoretical consequences, the most important being the inability to design deductive systems. Since the object level is untouchable (it's the language you want to deal with), one can fix the problem by `improving ́ the meta level; or one can also...

The linear accelerator (linac) is a device that uses highfrequency electromagnetic waves to accelerate charged particles such as electrons to high energies through a linear tube. The high-energy electron beam can be used for treating superficial tumours, or it can be made to strike a target to produce x-rays for treating deep-seated tumours. In the majority of instances, the collimated beam eme...

Optimum nuclear parton distributions are determined by an analysis of muon and electron deep inelastic scattering data. Assuming simple A dependence and polynomial functions of x and 1−x for nuclear modification of parton distributions, we determine the initial distributions by a χ 2 analysis. Although valence-quark distributions are relatively well determined except for the small-x region, ant...

The first measurements of the cross sections for neutral and charged current deep inelastic scattering in ep collisions with longitudinally polarised positron beams are presented. The total cross section for ep charged current deep inelastic scattering is presented at positive and negative values of positron beam longitudinal polarisation for an integrated luminosity of 37.0 pb H1 data and 30.5...
