Abstract:
Systems, methodologies, media, and other embodiments associated with activity factor based design are described. One exemplary system embodiment includes an activity factor logic configured to determine an activity factor for a first node. The activity factor relates an input activity for the first node to an output activity for the first node. The example system may also include a transmission factor logic configured to determine a transmission factor for the first node. The transmission factor describes a degree of causal power switching between the first node and a second node. The example system may also include a downstream power logic operably connected to the activity factor logic or the transmission factor logic. The downstream power logic may be configured to determine a power consumption amount for the second node. The power consumption amount may depend, for example, on the activity factor and the transmission factor.
Abstract:
The invention is directed to a method and composition of matter for enhancing the staining of tissue or features of interest therein by applying an effective amount of a bile salt in combination with a special stain to a tissue suspected of harboring a microorganism or other feature of diagnostic interest. The particular invention herein is directed to detecting H. pylori, the microorganism responsible for gastrointestinal ulcers. The composition of matter is a sensitizer for Alcian Yellow stain.
Abstract:
Methods and compositions for identifying high-grade cervical disease in a patient sample are provided. The methods of the invention comprise detecting overexpression of at least one biomarker in a body sample, wherein the biomarker is selectively overexpressed in high-grade cervical disease. In particular claims, the body sample is a cervical smear or monolayer of cervical cells. The biomarkers of the invention include genes and proteins that are involved in cell cycle regulation, signal transduction, and DNA replication and transcription. In particular claims, the biomarker is an S-phase gene. In some aspects of the invention, overexpression of a biomarker of interest is detected at the protein level using biomarker-specific antibodies or at the nucleic acid level using nucleic acid hybridization techniques. Kits for practicing the methods of the invention are further provided.
Abstract:
A method for performing color conversion includes configuring a color transformer to perform black point scaling when converting image data from a source device to a destination device. Another method for performing black point adjustment while performing color management conversions includes determining a device independent black reference vector for a device that corresponds to a predetermined set of device dependent values for that device. Converting the device dependent values to device independent data and adjusting the device independent data based on the device independent black reference vector.
Abstract:
A color mapping method is used in transforming colors between color imaging systems. The method includes using forward transformation profiles that characterize the color imaging systems to generate respective sets of device-independent color values for the color imaging systems. Color conversions are calculated by recursively reducing differences between the respective sets of device-independent color values. Based on these color conversions, a color map is constructed that describes a relationship between the color imaging systems.
Abstract:
Methods and computer program products for evaluating and optimizing one or more markers for use in establishing a prognosis for a patient suffering from a disease are provided. More particularly, the methods include steps for systematically evaluating a number of features that may be extracted from an image of a body sample, such as a histological slide, that has been exposed to one or more biomarkers so as to establish a prognostic decision rule based on one or more of the extracted features such that the decision rule yields a prognosis that is optimally predictive of actual patient outcome. Thus, the methods and computer program products provided yield optimally predictive prognoses to assist clinicians in developing strategies for effective patient care management.
Abstract:
One embodiment of the invention comprises, in each clock zone of a central processing unit, at least one sensor that generates a power signal indicative of a power supply voltage within the clock zone, a clock generator for providing a variable frequency clock to the clock zone, and a controller for controlling an operating frequency of the clock generator in response to the power signal and in response to frequency adjustment communications from other clock zones.
Abstract:
In a pipelined computer architecture in which instructions may be removed from the instruction queue out of sequence, instruction queue status at a cycle K is determined by adding together the number of invalid instructions or free rows in the queue during cycle K-2, the number of instructions issued for cycle K-1 and the number of instructions speculatively issued in cycle K-1 that have produced a cache hit, and subtracting from the sum the number of instructions enqueued for cycle K-1. The result indicates the number of invalid instructions in the queue cycle K. The number of invalid entries instructions, the number of issued instructions, and the number of enqueued instructions are preferably represented as flat vectors, so that adding is performed by shifting in one direction, while subtracting is performed by shifting in the opposite direction. The result is compared with either the number of instructions to be enqueued in the present cycle, which number is encoded, or with a predetermined value. A stall signal is generated if the indicative value is less than the encoded number or the predetermined value.
Abstract:
Screening methods for identifying patients with an increased likelihood of having ovarian cancer are provided. The screening methods involve the detection of expression of a plurality of biomarkers in a body sample, wherein overexpression of the biomarkers is indicative of an increased likelihood of having ovarian cancer. The screening methods may further comprise a two-step analysis. Biomarkers of interest include genes and proteins that are, for example, involved in defects in DNA replication/cell cycle control, cell growth and proliferation, escape from apoptosis, angiogenesis or lymphogenesis, or the mechanisms of cancer cell motility and invasion. In some aspects of the invention, expression of a biomarker is detected at the protein level using a biomarker-specific antibody or at the nucleic acid level using nucleic acid hybridization techniques. Methods for detecting ovarian cancer in patients are further disclosed herein. Kits for practicing the methods of the invention are further provided.
