Abstract: Methods for determination of risk, previous history and/or presence of a betaretrovirus infection in a subject are described herein. Said methods may comprise incubating a biological sample from the subject, the biological sample comprising immune effector-producing cells, with one or more betaretrovirus-specific epitopes, the betaretrovirus-specific epitopes comprising at least 7 contiguous amino acids according to any one of SEQ ID Nos. 1-36, and measuring the production of immune effectors by the immune effector-producing cells, wherein production of the immune effectors by the immune effector-producing cells determines risk and/or presence of betaretrovirus infection in the subject. Isolated peptides and kits for carrying out the methods are also described.

Abstract: A method for evaluating brittleness of a deep shale reservoir and a computer readable storage medium. The method includes determining a Rickman brittleness index of the deep shale reservoir and determining an effective pressure of the deep shale reservoir according to a pore pressure and an overlying formation pressure of the deep shale reservoir. The Rickman brittleness index is adjusted to obtain the brittleness index of the deep shale reservoir according to an exponential relationship of the brittleness index with the effective pressure of the deep shale reservoir. Inherent properties, such as rock brittle mineral content and the like, are better indicated by the Rickamn brittleness index, and then the brittleness index of the deep shale reservoir is obtained by utilizing the exponential relationship of the brittleness index with the effective pressure of the deep shale reservoir, to realize reasonable evaluation for the brittleness of the deep shale reservoir.

Abstract: An external cavity diode laser system includes a thin film filter. The output facet of the laser diode is coated with a partial reflection coating and the cavity side facet is coated with an anti-reflection coating. A roof-top prism or corner cube retroreflector serves as the laser cavity end reflector and provides stability of the wavelength of the output over time. The laser cavity lies between the partial reflective coated facet of the laser diode and retroreflector. A collimating lens and a thin film filter are located between the end reflector and the laser diode cavity side facet. The lasing wavelength can be adjusted during either manufacture or operation by tilting the filter. Also included is thermal compensation in the mounting for the retroreflector to compensate for thermal movement of the laser system cavity.
