Abstract: Robust classification methods analyse magnetic resonance spectroscopy (MRS) data (spectra) of fine needle aspirates taken from breast tumours. The resultant data when compared with the histopathology and clinical criteria provide computerized classification-based diagnosis and prognosis with a very high degree of accuracy and reliability. Diagnostic correlation performed between the spectra and standard synoptic pathology findings contain detail regarding the pathology (malignant versus benign), vascular invasion by the primary cancer and lymph node involvement of the excised axillary lymph nodes. The classification strategy consists of three stages: pre-processing of MR magnitude spectra to identify optimal spectral regions, cross-validated Linear Discriminant Analysis, and classification aggregation via Computerised Consensus Diagnosi s. Malignant tissue was distinguished from benign lesions with an overall accuracy of 93%. From the same spectrum, lymp h node involvement was predicted with an accuracy of 95% and tumour vascularisation with an overall accuracy of 92%.

Abstract: A method for manufacturing multi-laminar wood sheets by slicing from a flitch of natural and/or laminated wood sheets glued and pre-printed with a basic pattern. According to the method, a basic pattern is printed on one or both faces of wood sheets obtained by rotary cutting or slicing a natural log or a multi-layered flitch; the printed sheets are subsequently used to form a final flitch from which multi--laminar wood sheets are then sliced having a pattern designed to simulate different types of natural or fancy woods. The basic pattern is printed while maintaining process conditions designed to control the penetration into the thickness of the wood sheet and surface diffusion of the colouring agent during printing step. The penetration and diffusion of the colouring agent is controlled by maintaining specific temperature and pH conditions, and by controlling the quantity of colouring agent lay down on the surface of the wood sheets during the printing of the pattern.

Title: Methods for preventing reovirus recognition for the treatment of cellular proliferative disorders
Inventor: COFFEY MATTHEW C
IPC: C12N9/12
Filed: 2001-07-20
Granted: 2006-03-28
Abstract: The present invention pertains to methods for preventing reovirus recognitio n in the treatment of cellular proliferative disorders, and particularly ras- mediated cellular proliferative disorders, in mammals. The mammal may be selected from dogs, cats, sheep, goats, cattle, horses, pigs, mice, humans a nd non-human primates. The method comprises suppressing or otherwise inhibiting the immune system of the mammal and, concurrently or subsequently, administering to the proliferating cells an effective amount of one or more reoviruses under conditions which result in substantial lysis of the proliferating cells. In particular, the methods provide for reovirus treatme nt of immunosuppressed or immuno-deficient mammals to treat the proliferative disorders. Immunosuppression,immunoinhibition or otherwise inducing an immunodeficient state in a mammal renders the reovirus more effective. The methods may include the selective removal of immune constituents that may interfere with the systemic delivery of the virus; preventing reovirus recognition by the host immune system; and removal of the virus from an immu ne suppressed or immune incompetent host following treatment with reovirus. Alternatively, reovirus may be administered to a mammal with a diminished immune response system under conditions whichresult in substantial lysis of the proliferating cells. Immune systems may be compromised by one or more of the following: an HIV infection; as a side effect of chemotherapy or radiati on therapy; by selective removal of B and/or T cell populations; by removal of antibodies (anti-antireovirus antibodies or all antibodies), and the like.</ SDOAB>

Title: Method and system for reducing inter-symbol interference effects in transmission over a serial link with mapping of each word in a cluster of received words to a single transmitted word

Granted: 2005-05-03
Abstract: A communication system including a transmitter (1'), a receiver (2'), and a serial link, in which encoded data (e.g., encoded video data and encoded auxiliary data) are transmitted from the transmitter (1') to the receiver (2'). The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, alternating bursts of encoded video data and auxiliary data are transmitted over each of one or more channels of the link. Other aspects of the invention are transmitters for use in encoding data for transmission over a serial link, receivers for receiving such data, and methods for sending encoded data over a serial link. In accordance with the invention, source data to be transmitted are encoded using a subset of a full set of code words. The subset consist of preferred code words. The preferred words are predetermined such that each encoded data stream (comprising only preferred words) transmitted over a serial link has a bit pattern that is less susceptible to inter-symbol interference ("ISI") during transmission than is the bit pattern determined by a conventionally encoded version of the same data (comprising not only preferred words but also other members of the full set). Disjoint clusters of code words in the full set are predetermined. Each cluster includes one or more of the preferred words, and optionally also at least one additional code word that is similar to a preferred word of the cluster in the sense that is likely to be generated as a result of probable bit errors in transmission, or transmission and decoding, of such preferred word. In some embodiments, the preferred words have serial bit patterns (during transmission) that have fewer contiguous zeros and ones (and thus are less susceptible to ISI during transmission) than do code words in the full set that are not preferred words.
