20140077890 | CLASS-F CMOS OSCILLATOR - A novel and useful oscillator topology demonstrating an improved phase noise performance that exploits the time-variant phase noise model with insights into the phase noise conversion mechanisms. The oscillator is based on enforcing a pseudo-square voltage waveform around an LC tank by increasing the third-harmonic of the fundamental oscillation voltage through an additional impedance peak. Alternatively, the oscillator is based on enforcing clipped oscillation waveform by increasing the second harmonic of the fundamental oscillation voltage through an additional impedance peak. This auxiliary impedance peak is realized by a transformer with moderately coupled resonating windings. As a result, the effective impulse sensitivity function (ISF) decreases thus reducing the oscillator's effective noise factor such that a significant improvement in the oscillator phase noise and power efficiency are achieved. | 03-20-2014 |

20130085082 | METHODS FOR HAPLOTYPING SINGLE CELLS - We developed a generic approach to type genome-wide single nucleotide polymorphisms in single human cells and to reconstruct for the first time genome-wide haplotypes of single- or dual-cell derived genotypes. Proof-of-principle is delivered for EBV-transformed lymphoblastoid cells as well as human blastomeres. To this end, multiple displacement amplified DNA samples of single cells were hybridized to Affymetrix 250K SNP-arrays. Different algorithmic designs were subsequently developed to assess from the single-cell derived SNP-probe intensities the sequence of syntenic alleles and to pinpoint accurately the majority of parental homologous recombination sites across the entire genome using a linkage-based approach. This included the development of algorithms that rectify a large part of the discrepant allelic assignments in raw single or dual-cell derived haplotypes. This method to infer genome-wide haplotypes from the analysis of only one or two cells has tremendous applicative value. It has the capacity to revolutionize not only genetic diagnosis of preimplantation in vitro fertilized human embryos in the clinic, but also animal breeding programs by enabling genome-wide quantitative trait loci selection at the embryonic level. In addition, it allows to further scrutinize drivers of haplotype diversity, mainly meiotic homologous recombination as well as somatic (homologous) recombination processes that occur often during (human) tumorigenesis. | 04-04-2013 |

20140241618 | Combining Region Based Image Classifiers - Examples disclosed herein relate to combining region based image classifiers. In one implementation, a processor measures correct classification and misclassification levels associated with a first image classifier related to a first image feature region and measures correct classification and misclassification levels associated with a second image classifier related to a second image feature region. The processor may create a combined classifier based on the first image classifier correct classification and misclassification levels and based on the second image classifier correct classification and misclassification levels such that the combined classifier is related to the first image feature region and the second image feature region. | 08-28-2014 |
