摘要： A number of features for enhancing the performance of a cable transmission system in which data is transmitted between a cable modem termination system at a headend and a plurality of cable modems located different distances from the headend. The power transmission level, slot timing, and equalization of the cable modems are set by a ranging process. Data is transmitted by the modems in fragmented form. Various measures are taken to make transmission from the cable modems robust. The upstream data transmission is controlled to permit multiple access from the cable modems.

摘要： Extracts of vetiver oil were found to significantly repel termites. In one extract, nootkatone was isolated and found to be a significant repellent and toxicant of termites. Nootkatone significantly decreased food consumption, decreased tunneling behavior, and increased mortality in termites. Nootkatone is an effective repellent and toxicant of termites either by itself or as an addition to other materials or substrates, including mulches made from vetiver grass roots or other wood products. Nootkatone can also be used to protect construction wood from attack by Formosan subterranean termites. Nootkatone as a repellent is non-toxic to humans and other mammals and is environmentally safe. In addition, α-cedrene was found to be a weak termite repellent; and both zizanol and bicyclovetivenol were found to be repellents and toxicants of termites.

摘要： The present invention discloses a method and an in-vivo assay system useful for the identification and testing of modulating agents as well as for the validation of therapies of neurodegenerative diseases associated with the formation of neurofibrillary tangles, in particular Alzheimer's disease. The present invention is based on the surprising finding that injection of β-amyloid Aβ42 fibrils into brains of P301L mutant tau transgenic mice caused several-fold increases in the numbers and an accelerated production of neurofibrillary tangles in cell bodies predominantly within the amygdala. The induced neurofibrillary tangles occurred as early as 18 days after Aβ42 injections and displayed striking features of neurofibrillary tangles of several human neurodegenerative diseases, particularly Alzheimer's disease.

摘要： Improved separations of xylose, mannose, galactose, arabinose, glucose, xylitol, arabitol; sorbitol, galactitol, or mannitol (and other monosaccharides and sugar alcohols) from other sugars and sugar alcohols may be achieved by chromatography over hydroxyl-form anion exchange surfaces prepared from anion exchange resins at relatively low hydroxyl concentrations. When a strong base anion exchange resin, such as a chloride-form strong base anion exchange resin, is conditioned with a low concentration of hydroxyl (for example, an NaOH solution with a concentration between 0.1 and 1000 mM, most preferably between 1 and 10 mM), the conditioned resin separates a number of sugars and sugar alcohols from one another, while still allowing ready desorption from the resin.

摘要： A low voltage swing priority encoder comprising pass cells to provide differential voltages indicative of the leading one of a binary tuple. A tree structure with bypass paths allows for the minimization of the number of pass cells in a signal propagation path so as to reduce signal delay. The pass cells are responsive to control voltages indicative of various Boolean functions of the binary tuple, and a pulse voltage signal is applied to the pass cells. In response to the control voltages and the pulse voltage signal, the pass cells provide differential voltages so that voltage swing of the differential voltages are kept below the supply voltage to reduce dynamic power dissipation. Sense amplifiers sense the differential voltages to provide the final logic level indicative of the leading one of the binary tuple.

摘要： A motion estimating method for determining a motion vector, using a bit rate-distortion technique in image compression. The motion estimating method includes the steps of obtaining a motion vector (x.sub.o, y.sub.o) which minimizes a predetermined error function, assuming a preferred motion vector (x, y), calculating the difference (x-diff, y-diff) between (x.sub.o, y.sub.o) and (x, y), obtaining the number of bits needed to encode the x-diff and y-diff, determining a bias based on a bias model according to the bit number, obtaining a final cost function value based on the difference between a cost function value and a bias, comparing the final cost function value with a predetermined allowance limit, determining the assumed motion vector (x, y) as a motion vector for a current macroblock and updating the allowance limit by using the cost function value, if the cost function value is smaller than the predetermined allowance limit and discarding the assumed motion vector (x, y) if the cost function value is not smaller than the predetermined allowance limit. The disclosed method is successful in increasing the compression rate.

摘要： A method generates a reduced number of values representing a sequence of grouped data values and partitions the reduced number of values by first mapping data values into groups of symbols and then partitioning the resulting stream of symbols. The digits representing the first data value in each group are replaced with symbols from a first alphabet. The most significant digit of the second data value in each group and the sign of that second data value are also represented by a symbol from the first symbol set, while the remaining significant bits of the second data value in each group are represented by symbols from a second symbol set. A stream of symbols which represent a sequence of grouped data values is partitioned into first partition symbol groups and second partition symbol groups. Each first partition symbol group comprises the symbols representing the first data value in each group and also the symbol representing the least significant bit of the second data value which follows. Each second partition symbol group comprises the symbols representing all digits of a second data value excluding the symbol which represented the least significant digits.
