Method and apparatus for designing and manufacturing electronic circuits subject to process variations
Methods and apparatus are described in which, at design-time a thorough analysis and exploration is performed to represent a multi-objective “optimal” trade-off point or points, e.g. on Pareto curves, for the relevant cost (C) and constraint criteria. More formally, the trade-off points may e.g. be positions on a hyper-surface in an N-dimensional Pareto search space. The axes represent the relevant cost (C), quality cost (Q) and restriction (R) criteria. Each of these working points is determined by positions for the system operation (determined during the design-time mapping) for a selected set of decision knobs (e.g. the way data are organized in a memory hierarchy). The C-Q-R values are determined based on design-time models that then have to be “average-case” values in order to avoid a too worst-case characterization. At processing time, first a run-time BIST manager performs a functional correctness test, i.e. checks all the modules based on stored self-test sequences and “equivalence checker” hardware. All units that fail are deactivated (so that they cannot consume any power any more) and with a flag the run-time trade-off controllers, e.g. Pareto controllers, are informed that these units are not available any more for the calibration or the mapping. At processing time, also a set of representative working points are “triggered” by an on-chip trade-off calibration manager, e.g. a Pareto calibration manager, that controls a set of monitors which measure the actual C-Q-R values and that calibrates the working points to their actual values. Especially timing monitors require a careful design because correctly calibrated absolute time scales have to be monitored. |

Method, system and article for client application control of network transmission loss tolerance
A dynamically-enforceable application-controlled quasi-reliable extension to TCP permits a client application to dynamically set a percent loss tolerance for data transmission reliability through network input/output system calls to the TCP, thereby programming the transport layer to optimistically acknowledge non-critical missing frames. The reliability requirement can be dynamically set within TCP to the level of reliability required for specific data frames within the data stream during the data transfer. Based on this loss tolerance specified, the TCP layer makes a determination whether to trigger a retransmission or continue delivering out-of-order frames to the application. A forced acknowledgement frame is sent for each missing packet until the number missing packets causing forced acknowledgments within the current receive buffer frame exceeds the loss tolerance. This process avoids needless retransmissions and permits the TCP data flow and sliding window to advance uninterrupted, thereby providing substantial performance benefits to network throughput. |

The aggregator formulates a query without using privacy-sensitive information, and sends the query to the data consumer entity. The data consumer entity generates a list of specific instances that meet the conditions of the query and sends the list, encrypted, to the data source entities either directly or through the aggregator. The data source entities match the list against transactional data, de-identify the matched results, and send them to the aggregator. The aggregator combines results from data source entities and sends the combined result to the data consumer entity. This allows for privacy-safe data mining where both the data consumer entity and data source entities have privacy-sensitive information not available for the aggregator to see or use. |

Method for quantification of neurotoxin
The present invention relates to a method for quantitatively measuring the muscular relaxing activity of a neurotoxin. Specifically, based on an extent of the activity of muscular relaxation of a neurotoxin from bacteria of Clostridium, the present invention relates to a method for quantification of the efficacy (potential and/or diffusion reaction) of a neurotoxin comprising the following steps of: (a) administering a neurotoxin to the hind leg muscle of one of hind legs of a non-human mammal; (b) applying electric stimulus to said non-human mammal; (c) measuring a compound muscle action potential (CMAP) by contraction of said hind leg muscle to which the neurotoxin is administered and/or of the hind leg muscle of the other hind leg to which the neurotoxin is not administered; and (d) taking amplitude data from the compound muscle action potential (CMAP) obtained by the measurement in step (c) and analyzing an extent of a decrease in amplitude to thereby quantify the efficacy of the muscular relaxing activity by the neurotoxin. In contrast to the mouse LD50 currently used as a potential unit of a botulinum toxin which is measurable at a level of only several units, the quantification method of the efficacy of a neurotoxin of the present invention allows for measurement at a level of as low as 0.01 to 1 unit and hence is a method with a high sensitivity, reproducibility and accuracy. |

Shadow detection in a single image
A digital image is divided into patches of pixels, or “superpixels”, where each of the pixels in the patch has approximately the same color value and each of the patches is of approximately the same size. Subsequently, eigenvalues are generated for each patch based on the color values of the individual pixels in the patch, as expressed in a multidimensional color-space. A ratio between the first largest eigenvalue and the second largest eigenvalue for each patch is determined and is then, subsequently, normalized, either based on the intensity of the corresponding patch or normalized to a range between zero and one. The resulting values are compared to a threshold to identify those regions of the digital image that are deemed to be in shadow, thereby generating a shadow mask for the digital image, or are weighted to generate a shadow probability mask. |
