Abstract: The present invention demonstrates that the diagnosis and prediction of clinical behavior in patients with hematologic malignancies, such as leukemia, can be accomplished by analysis of proteins present in a plasma sample. Thus, in particular embodiments the present invention uses plasma to create a diagnostic or prognostic protein profile of a hematologic malignancy comprising collecting plasma samples from a population of patients with hematologic malignancies; generating protein spectra from the plasma samples with or without fractionation; comparing the protein spectra with clinical data; and identifying protein markers in the plasma samples that correlate with the clinical data. Protein markers identified by this approach can then be used to create a protein profile that can be used to diagnose the hematologic malignancy or determine the prognosis of the hematologic malignancy. Potentially these specific proteins can be identified and targeted in the therapy of these malignancies.

Abstract: Methods and apparatus utilizing hydrogen peroxide are useful to reduce SOx and mercury (or other heavy metal) emissions from combustion flue gas streams. The methods and apparatus may further be modified to reduce NOx emissions.  Continuous concentration of hydrogen peroxide to levels approaching or exceeding propellant-grade hydrogen peroxide facilitates increased system efficiency. In this manner, combustion flue gas streams can be treated for the removal of SOx and heavy metals, while isolating useful by-products streams of sulfuric acid as well as solids for the recovery of the heavy metals. Where removal of NOx emissions is included, nitric acid may also be isolated for use in fertilizer or other industrial applications.

Abstract: An apparatus for cooking food with infrared radiation includes an infrared energy emitter for emitting the infrared radiation, and a grid in close proximity to the infrared energy emitter. A first side of the grid can be for supporting the food at a position so that at least some of the infrared radiation will cook the food. A second side of the grid can be sufficiently close to the emitting side of the emitter for substantially restricting any airflow in any space between the second side of the grid and the emitting side of the emitter.

Title: Temperature step correction with double sigmoid levenberg-marquardt and robust linear regression
Inventor: KURNIK RONALD T
IPC: G06F17/17
Filed: 2006-12-18
Abstract: Systems and methods for improving Ct determination in PCR amplification curves by correcting PCR data for temperature shifts that may occur during the PCR process. A  double sigmoid function with parameters determined by a Levenberg-Marquardt (LM) regression process is used to find an approximation to the portion of the curve in the region after the temperature shift, termed "CAC", the cycle where the temperature shift occurred. A robust linear approximation is determined for the portion of the curve in the region before the temperature shift. Values of the fluorescent intensity for the cycle CAC or CAC+1 are determined using both the linear approximation and the LM  process, and a difference in these values is subtracted off of the portion of the data set representing the portion of the curve before the temperature shift occurred to produce a shift-corrected data set.  The shift-corrected data set may be displayed or otherwise used for further processing.

Abstract: L'invention porte sur un procédé de traitement des signaux audio, sur un appareil prenant en compte les signaux audio, sur un support qui effectue les instructions d'un processeur et sur un support de données de filtre pour mettre en oeuvre un filtre de signaux audio. Le procédé consiste à filtrer une paire de signaux d'entrée audio par un processus qui génère une paire de signaux de sortie correspondant aux résultats du filtrage de chacun des signaux d'entrée avec une paire de filtres HRTF( à fonction de transfert liée à la chaleur), et ajouter des signaux filtrés. La paire de filtres HRTF se présente de façon qu'un auditeur écoutant la paire de signaux de sortie par des écouteurs reçoive des sons provenant des deux emplacements virtuels des haut-parleurs. De plus, le filtrage permet que, dans le cas où la paire de signaux d'entrée audio comprend une composante de signal stéréo, l'auditeur écoutant la paire de signaux de sortie par des écouteurs ait la sensation que la composante du signal stéréo émane d'une source sonore virtuelle à un emplacement central se trouvant entre les haut-parleurs virtuels.

Abstract: A communications device for separating source signals provided by M signal sources includes an antenna array comprising N elements for forming at least N  antenna beams for receiving at least N different summations of the M source signals, with N and M being greater than 2. A controller is connected to the antenna array for selectively forming the at least N antenna beams. A blind signal separation processor forms a mixing matrix comprising up to the at least N different summations of the M source signals. The blind signal separation processor also determines if the different summations of the M  source signals are correlated or statistically independent, and if not, then cooperates with the controller for forming different beams for receiving new different summations of the M source signals to replace the different summations of the M source signals that are not correlated or statistically independent in the mixing matrix. The desired source signals are separated from the mixing matrix by the blind signal separation processor.
