Undoubtedly, the twentieth century can be regarded as one of the richest periods of the history of philosophy and thought which globalized this tradition, generally, because of the spread of mass media and even the published books, and joined all vast and narrow streams, here and there, together and at their Juncture a big sea is formed which is the most important gain of the century. One of t...

background and aims. in contrast to prepared natural dentin abutments, little is known concerning factors influencing the retention of fixed prostheses cemented to implant abutments. the aim of this study was to investigate the effect of implant abutment height on the retention of single castings cemented to wide and narrow platform implant abutments. materials and methods. thirty-six parallel-...

Leaf shape is one of the key determinants of plant architecture. Leaf shape also affects the amount of sunlight captured and influences photosynthetic efficiency; thus, it is an important agronomic trait in crop plants. Understanding the molecular mechanisms governing leaf shape is a central issue of plant developmental biology and agrobiotechnology. Here, we characterized the narrow-leaf pheno...

We derive an exact transfer-matrix solution for an infinite system of hard particles confined in a manner that precludes non-nearest-neighbor interactions. The solution takes the form of a functional eigenvalue equation which may be solved numerically for the thermodynamic and structural properties of the confined fluid. Barker [Aust. J. Phys. 15, 127 (1962)] originally derived this solution by...

The spectral width of a nonlinear converter is usually thought to be inversely proportional to the length of the nonlinear crystal. We present a method to overcome this limitation using the concept of super-oscillations, thus creating an arbitrarily narrow converter. A “super-narrow” frequency doubler was fabricated by appropriate modulation of its quadratic nonlinear coefficient, showing spect...

Narrow bandpass filters (NBPF) are an important type of thin film filter technology that have become commonplace within the electrooptics industry. These devices are indispensable in fields such as analytical instrumentation, microscopy and telecommunications. NBPF are typically characterized as having high transmission with steep roll-offs and broad isolation. Thin film coating designs that me...

A study of general properties of the narrow-width approximation (NWA) with polarization/spin decorrelation is presented. We prove for sufficiently inclusive differential rates of arbitrary resonant decay or scattering processes with an on-shell intermediate state decaying via a cubic or quartic vertex that decorrelation effects vanish and the NWA is of order Γ. Its accuracy is then determined n...

To satisfy the demand for higher performance, modern processors are designed with a high degree of speculation. While speculation enhances performance, it burns power unnecessarily. The cache, store queue, and load queue are accessed associatively before a matching entry is determined. A significant amount of power is wasted to search entries that are not picked. Modern processors speculatively...
