Programmatic compiler optimization of glacial constants
Optimizations are programmatically applied by a compiler (preferably, a just-in-time or “JIT” compiler), and enable achieving improved performance while a variable acts as a global constant, yet also allow code to execute correctly if the global constant's run-time value changes from the value on which the optimization was originally based. Code snippets that dynamically patch executable code are described, where these code snippets take corrective actions to enable correct program execution following a run-time change to the value of a glacial constant. A backup recovery path may also be maintained, where this path provides code that is executed in the event of a change to a glacial constant and that treats the glacial constant as a variable. Recompilation may also be used after a change to a glacial constant, where the originally-compiled code has made an assumption about the glacial constant's value that is no longer accurate. Combinations of these approaches may be used. |

System and method for matching a plurality of ordered sequences with applications to call stack analysis to identify known software problems
The invention finds matches in ordered sequences, e.g. program function call stacks from anomalous software program executions for discovering related or identical software flaws and possible known solutions. Call stacks are matched after removing recursive and uninformative subpatterns, e.g. names of common error handling routines, to see if they were generated due to the same possibly known problem. Sequences statistically unlikely to be matches are pruned from the search. Matches found earlier in the sequences may be weighted differently, e.g. to be more important in call stacks, than other matches. Sequences are indexed so that those relevant to a query are identified automatically without detailed exhaustive search. Maximum matches are found by optimizing a cost function based on weighted sequence similarity. |

Methods for spectral image analysis by exploiting spatial simplicity
Several full-spectrum imaging techniques have been introduced in recent years that promise to provide rapid and comprehensive chemical characterization of complex samples. One of the remaining obstacles to adopting these techniques for routine use is the difficulty of reducing the vast quantities of raw spectral data to meaningful chemical information. Multivariate factor analysis techniques, such as Principal Component Analysis and Alternating Least Squares-based Multivariate Curve Resolution, have proven effective for extracting the essential chemical information from high dimensional spectral image data sets into a limited number of components that describe the spectral characteristics and spatial distributions of the chemical species comprising the sample. There are many cases, however, in which those constraints are not effective and where alternative approaches may provide new analytical insights.For many cases of practical importance, imaged samples are “simple” in the sense that they consist of relatively discrete chemical phases. That is, at any given location, only one or a few of the chemical species comprising the entire sample have non-zero concentrations. The methods of spectral image analysis of the present invention exploit this simplicity in the spatial domain to make the resulting factor models more realistic. Therefore, more physically accurate and interpretable spectral and abundance components can be extracted from spectral images that have spatially simple structure. |

Minimizing effects of dye crosstalk
Methods and systems for processing signals to minimize the effects of dye crosstalk. Deconvolution of multiplexed dye signals can include corrections for residual error determined from experimental measurements. Residual error corrections can account for reaction or assay specific factors and modify the subsequent filtering of signals. Correction values can be determined for specific dye-probe conjugates to minimize dye crosstalk and may be combined with residual error correction to further minimize errors in spectral deconvolution. Apparatus, systems, and computer-readable media can process signals and modify filters based on values obtained using the methods. |

Apparatus, method and computer program for spectroscopic measurements and analysis
The present invention relates to a spectroscopic method and associated apparatus and computer program for measuring and analysing intensities of fluorescent molecules excited by an energy pulse. The method includes the steps of: a) generating a transient state build-up in the fluorescent molecules by means of an excitation pulse, within which pulse repetitive excitation-emission cycles are induced in the fluorescent molecules between their ground, typically singlet (So) and excited, typically singlet (SO states, resulting also in transition from S] to the transient state, b) relaxation of population of the transient state by transition back to the ground state in a time period following directly after the excitation pulse, c) determination of the transient state population by recording the fluorescence. The invention is characterised by varying pulse characteristics from one sequence of pulses to the next so as to circumvent the need of time-resolution in the detection. |
