  • Publication number: 20190294684
    Abstract: A software input string is received and tokenized into a sequence of tokens. The sequence of tokens is applied to a trained sequence-dependent lock/unlock classifier so that each of the tokens is classified as a token that should be locked, or remain unlocked, for subsequent translation. The software input string is converted to a converted string, in which the locked tokens are identified and the converted string is submitted for machine translation. A machine translation result is received and converted so that the locked tokens are replaced in the machine translation result, to obtain a translated software string.

  • Publication number: 20190233901
    Abstract: An apoptosis regulatory gene is detected in an irradiated-thymic lymphoma cell by a method for detecting such an apoptosis regulatory gene in a low-dose-rate and low-level-irradiated thymic lymphoma cell of a mouse. This has an effect of revealing the function of an apoptosis regulatory gene by means of irradiation and providing a gene profile, by detecting an apoptosis regulatory gene detected in an irradiated-thymic lymphoma cell. The detected apoptosis regulatory gene is used to construct a gene profile that can assess the dose-response relationship of industrial and healthcare workers living in a low level-radiation environment. The detected apoptosis regulatory gene can be used as an index for evaluating the extent of cancer progression and the degree of treatment in patients with thymic lymphoma. The method for detecting such an apoptosis regulatory gene is used to prepare for the prepare a composition for diagnosing thymic lymphoma and a diagnostic kit.

  • Publication number: 20190153950
    Abstract: Disclosed herein is a gas turbine and a method of cooling the same. A cooling air supply passage of extracting air out of a compressor of the gas turbine and diverting the air to the outside is formed, and vanes and blades of a turbine are cooled by such cooling air supply passage that does not pass through a central shaft of the gas turbine. Consequently, the consumption of cooling air may be reduced while cooling efficiency is not affected, and the flow rate of cooling air may be more easily controlled.
