Abstract: Methods and compositions are provided for efficiently preparing and manufacturing pentostatin. Also provided are novel precursors of pentostatin, pentostatin analogs and derivatives. In one aspect of the invention, a method is provided for total chemical synthesis of pentostatin via a route of heterocyclic ring expansion. For example, a heterocyclic pharmaceutical intermediate for drugs such as pentostatin, e.g., the diazepinone precursor, can be obtained efficiently through a ring expansion of an O-C-N functionality in a hypoxanthine or 2'-deoxyinosine derivative. The methods and compositions can also be used to synthesize and manufacture heterocyclic compounds other than pentostatin, especially pharmaceutically important heterocyclic compounds.

Abstract: An electroactive material and a method of manufacturing the same is provided, in which the primary component of the electroactive material is a metal boron oxide complex, and the electroactive material exhibits excellent charge/discharge characteristics.  The electroactive material of the present invention is primarily composed of an amorphous metal complex represented by the general formula M2-2X B2X O3. M is one or two or more metal elements selected from the transition metal elements, e.g., Fe or V. In addition, x is 0 < x <  1, e.g., 1/2. This type of electroactive material can be manufactured by amorphizing the metal complex represented by the general formula M2-2X B2X O3 by means of a mechanical milling method. In addition, the electroactive material can be manufactured by rapidly cooling and solidifying a mixture containing an oxide in which M is a constituent metal element and a boron oxide from the melted state.

Granted: 2012-10-16
Abstract: A video display for digitized video data interpolates values between time samples, such as luminance over a horizontal line or over an average of all the horizontal lines in a video signal, so as to produce a digitally plotted test display resembling the continuous line display of an oscilloscope. A  digital impulse response filter has stored coefficients that contribute as factors to the values of interpolated data points to fill the line display between sample values. Instead of changing the coefficients to produce variations interpolating the output between sample values, the coefficients are held constant and a delay factor is varied to alter the extent to which the respective coefficients and sample values interact and contribute to the interpolated values.
