Hong Kong, China

The Chinese University of Hong Kong is a public research university in Shatin, Hong Kong, formally established in 1963 by a charter granted by the Legislative Council of Hong Kong. It is the territory's second oldest institution of higher learning, and the only collegiate university. The University was originally founded as a federation of three existing colleges, Chung Chi College, New Asia College and United College, the oldest of which was founded in 1949.Today, CUHK is organised into nine constituent colleges and eight academic faculties. Though the original statement in the charter of the University stipulates Chinese as the principal language, English is currently the main language of instruction in most classes, with Cantonese and Mandarin Chinese being retained only by a minority of colleges and academic departments. As of 2013, four Nobel laureates are associated with the University, making it the only tertiary institution in the territory with recipients of the Nobel Prize, Turing Award, Fields Medal and Veblen Prize as faculty in residence.

Embodiments may include a method of determining a nucleic acid sequence. The method may include receiving a plurality of DNA fragments. The method may also include concatemerizing a first set of the DNA fragments to obtain a concatemer. The method may include performing single-molecule sequencing of the concatemer to obtain a first sequence of the concatemer. In some embodiments, single-molecule sequencing may be performed using a nanopore, and the method may include passing the concatemer through a nanopore. A first electrical signal may then be detected as the concatemer passes through the nanopore. The first electrical signal may correspond to a first sequence of the concatemer. In addition, the method may include analyzing the first electrical signal to determine the first sequence. Subsequences of the first sequence may be aligned to identify sequences corresponding to each of the first set of the DNA fragments.

Embodiments of the present invention provide methods, systems, and apparatus for deducing the fetal DNA fraction in maternal plasma without using paternal or fetal genotypes. Maternal genotype information may be obtained from a maternal-only DNA sample or may be assumed from shallow-depth sequencing of a biological sample having both maternal and fetal DNA molecules. Because sequencing may be at shallow depths, a locus may have only few reads and may fail to exhibit a non-maternal allele even if a non-maternal allele is present. However, normalized parameters that characterize non-maternal alleles sequenced can be used to provide an accurate estimate of the fetal DNA fraction, even if the amount of non-maternal alleles is in error. Methods described herein may not need high-depth sequencing or enrichment of specific regions. As a result, these methods can be integrated into widely used non-invasive prenatal testing and other diagnostics.

BATS protocols may be utilized for high efficiency communication in networks with burst or dependent type losses. Systematic recoding at intermediate network nodes may be utilized to reduce the computational cost during recoding. A block interleaver based BATS protocol may be utilized to handle burst loss, where batches are recoded to a same number of packets. Adaptive recoding may be utilized to improve the throughput, where a batch with a higher rank is recoded to a larger number of packets. Using adaptive recoding, a non-block interleaver based BATS protocol may be utilized.

Embodiments are related to the accurate detection of somatic mutations in the plasma (or other samples containing cell-free DNA) of cancer patients and for subjects being screened for cancer. The detection of these molecular markers would be useful for the screening, detection, monitoring, management, and prognostication of cancer patients. For example, a mutational load can be determined from the identified somatic mutations, and the mutational load can be used to screen for any or various types of cancers, where no prior knowledge about a tumor or possible cancer of the subject may be required. Embodiments can be useful for guiding the use of therapies (e.g. targeted therapy, immunotherapy, genome editing, surgery, chemotherapy, embolization therapy, anti-angiogenesis therapy) for cancers. Embodiments are also directed to identifying de novo mutations in a fetus by analyzing a maternal sample having cell-free DNA from the fetus.

Systems, apparatuses, and method are provided for determining the contributions of different tissues to a biological sample that includes a mixture of cell-free DNA molecules from various tissues types, e.g., as occurs in plasma or serum and other body fluids. Embodiments can analyze the methylation patterns of the DNA mixture (e.g., methylation levels at particular loci) for a particular haplotype and determine fractional contributions of various tissue types to the DNA mixture, e.g., of fetal tissue types or tissue types of specific organs that might have a tumor. Such fractional contributions determined for a haplotype can be used in a variety of ways.

Masers and microwave amplifiers that can function in the continuous-wave mode at room temperature are provided. The maser system can include a diamond gain medium having nitrogen-vacancy centers, and a resonator can be disposed around the gain medium. The resonator can be disposed in a cavity box, and radiation (e.g., visible light) can be provided to the gain medium to cause emission of microwave radiation.

This application describes the discovery that, in a pregnant woman, certain genes (such as RASSFIA, APC, CASP8, RARB, SCGB3A1, DAB2IP, PTPN6, THYl, TMEFF2, and PYCARD) originated from a fetus are highly methylated, whereas the same genes of maternal origin are unmethylated. This discovery allows the easy detection of one or more of these methylated fetal genes in a biological sample from a pregnant woman, serving as a universal indicator of the presence of fetal DNA in the sample. These fetal methylation markers are particularly useful as positive controls for a non-invasive analytical process during which the quality and quantity of fetal DNA are monitored. These newly identified fetal markers can also be measured directly for diagnosis of certain pregnancy-related conditions.
