Patent CA-2244380-A1 (CA)
Title: Z-coder: a fast adaptive binary arithmetic coder
Inventor: BOTTOU LEON
IPC: H03M7/30
Filed: 1998-07-27
Abstract: A  binary  arithmetic  coder  and  decoder  provides improved  coding  accuracy  due  to  improved  probability estimation and adaptation.  They also provide  improved decoding  speed  through  a  "fast  path"  design  wherein decoding  of  a  most  probable  symbol  requires  few computational steps. Coded data represents data that is populated  by more  probable  symbols  ("MPS")  and  less probable symbols  ("LPS").   In an embodiment, a decoder receives  a  segment  of  the  coded  data  as  a  binary fraction C.   It defines a coding interval of possible values  of  C,  the  interval  extending  from a  variable lower bound A to a constant upper bound 1.   For each position  in  the  decoded  symbol  string,  the  decoder computes  a  test  value  Z  that  subdivides  the coding interval  into sub-intervals according to the  relative probabilities  that  an  MPS  or  an  LPS  occurs  in  the position.   A first sub-interval extends from the lower bound A to the test value Z;  the second sub-interval extending from the test value Z to 1.   If C is greater than  Z,  the  decoder  emits  an  MPS  for  the  current position in the decoded symbol string and sets the lower bound A to the test variable Z for use during decoding of the next position in the decoded symbol string.  If C is less than Z, the decoder emits an LPS and computes a new lower bound A and a new binary fraction C for use during  decoding  of  the  next  position  in  the  decoded symbol  string.    The  encoder  operates  according  to analogous techniques to compose coded data from original data.

Title: Method of managing the chemotherapy of patients who are hiv positive based on the phenotypic drug sensitivity of human hiv strains
Inventor: DE BETHUNE MARIE-PIERRE
IPC: C12Q1/70
Filed: 1997-01-24
Abstract: A method of managing HIV chemotherapy of patients who are HIV positive comprises transfecting a cell line susceptible to infection by HIV with a sequence, preferably that coding for RT and protease, from the pol gene of HIV obtained from a patient and a HIV-DNA construct from which the sequence has been deleted, culturing the transfected cells so as to create a stock of chimeric viruses, assessing the phenotypic sensitivity of the chimeric viruses to an inhibitor of the enzyme encoded by the pol gene of HIV and assigning a value thereto, constructing a data set comprising the value for chimeric virus sensitivity and the corresponding value for a chimeric wild-type strain of HIV, repeating the sensitivity assessment for at least two further inhibitors and thereby constructing at least three such data sets in total, representing the data sets in two-dimensional or three-dimensional graphical form such that the difference between the chimeric and wild-type sensitivities in the case of each data set provides a visual measure of the resistance of the chimeric stock to treatment by the inhibitor in question, and selecting the optimum inhibitor(s) on the basis of the graphical representation of the resistances so measured. The method yields phenotypic information on individual HIV infected patients on a large scale, economically and rapidly. The method is applicable to all currently available chemotherapeutic regimens and it is expected to be equally applicable to future chemotherapeutic regimens.

Abstract: A combination fiber optic/electrical well logging cable comprising at least one insulated electrical conductor and a plurality of armor wires surrounding the electrical conductor. The armor wires include at least one tube having an optical fiber disposed inside the tube. In a preferred embodiment, the armor wires are disposed in two concentric layers circumscribing the electrical conductor. One or more of the armor wires in the innermost layer of armor wires includes the tube having the optical fiber disposed therein. The tube has an external diameter which is substantially the same as the armor wires in the layer in which the tube is located. The inner diameter of the tube is selected to provide just enough room for the optical fiber to move about freely, but to retain enough crush strength for the tensile and side loads expected to be applied to the cable. In a particular embodiment, the tube includes an inner layer consisting of a thin walled tube, a metal foil layer wrapped around the outside of the inner layer, and an outer layer consisting of another thin walled tube on the outside of the foil layer.

Abstract: L'invention concerne un animal eucaryote non humain transgénique dont les cellules germinales et les cellules somatiques contiennent la séquence de la protéine précurseur amyloïde introduite dans l'animal, ou bien un ancêtre de cet animal, à un stade embryonnaire. Chez les souris se développe un trouble du système nerveux central lié à l'âge et caractérisé par une agitation, la néophobie, des attaques, une inactivité, une utilisation réduite du glucose cérébral, une gliose cortico-limbique, et la mort. Une accélération de ce trouble survient chez les souris transgéniques s'exprimant des protéines précurseurs amyloïdes d'Alzheimer (APP) humaines et de souris produites à l'aide d'un vecteur cosmide dérivé d'un gène protéique de prion de hamster conférant une expression qui est dépendante du nombre de copies mais indépendante de la position. Chez les souris transgéniques, ce trouble se développe en relation directe avec la concentration cérébrale d'APP transgénique, mais l'APP mutante confère le phénotype à des niveaux d'expression plus faibles que l'APP de type sauvage. Ce trouble survient en l'absence de dépôt de plaques amyloïdes extracellulaires, ce qui indique que certaines activités pathogènes de l'APP sont dissociées de la formation de plaques amyloïdes.
