Abstract: Solved is the following problem: a PE based resin including a film grade ethylene-?-olefin copolymer is excellent in economic efficiency, but has a narrow molecular weight distribution in consideration for strength and heat sealability, and therefore causes surface roughening to occur when applied to a covering material for an insulated electric wire or cable. Applied is a polyolefin based resin composition including at least one polyethylene (PE) based resin, in which, when a ratio (I10/I0.5) of an MFR (I10) measured at 190° C. and a load of 10 kg to an MFR (I0.5) measured at 190° C. and a load of 0.5 kg is defined as MFRR, a difference between the MFRR of the polyolefin based resin composition including at least one PE based resin and the MFRR of the PE based resin is 5 or more.

Abstract: Solved is the following problem in terms of outer appearance: a covered electric wire obtained by extrusion of a low cost linear polyethylene resin (LLDPE) has irregularities formed on the surface thereof because processing suitability of LLDPE is poor. As a solution to the problem, a resin composition including 50 to 97 parts by weight of LLDPE and 3 to 50 parts by weight of a polypropylene (PP) based resin can be used to thereby produce a covered electric wire excellent in surface smoothness at a high speed and a low cost.

Abstract: Embodiments relate to updating a parameter defining a policy under a Markov decision process system environment. An aspect includes updating the policy parameter stored in a storage section of a controller according to an update equation. The update equation includes a term for decreasing a weighted sum of expected hitting times over a first state (s) and a second state (s?) of a statistic on the number of steps required to make a first state transition from the first state (s) to the second state (s?).

Abstract: To provide a rat model with the onset of prostate cancer in which the prostate cancer including an invasive cancer can be developed and can be bred for generations stably. A rat model with the onset of prostate cancer which can develop prostate cancer including invasive cancer and can be bred for generations stably is established by: ligating an SV40 large T antigen gene onto the downstream of rat probasin gene promoter; the resulting PBSVT transgene is introduced into a fertilized egg of a Sprague-Dawley rat; after the introduction, the fertilized egg is transplanted into a recipient rat; a transgenic rat obtained from the recipient rat is then mated with a wild-type Sprague-Dawley rat; the transgenic offspring rats thus obtained are similarly can be bred for generations thereafter; and transgenic rats developing prostate cancer are selected through histopathological observation of the prostate.

Abstract: In order to make it possible to detect a carcinogen highly sensitively and more easily in a short time, the present invention provides a rat having a high sensitivity to a carcinogen, and a method for detecting carcinogens using the rat, and a method for screening anticancer substances using the rat made to develop a cancer. It has been found that a rat whose normal function in gap junction is inhibited has a high sensitivity to a carcinogen. For the inhibition of normal function in gap junction, part of a connexin gene is made to be deficient and a plasmid vector engineered to carry a gene deficient in connexin function is introduced into a rat to make a transgenic rat. By using the rat of the present invention, it becomes possible to detect a carcinogen highly sensitively and more easily in a short time, and the rat of the present invention made to develop a cancer can be effectively used for the screening of anticancer substances.

Abstract: A relative velocity sensing device for sensing an optical beam spot, for example, by using a tracking error difference signal that fluctuates as a sine-wave in accordance with a movement of the beam spot. The tracking error difference signal is converted into a first sawtooth wave signal, and a second sawtooth wave signal, having a phase which is offset from the first sawtooth wave signal by one half of the period thereof. A first differential signal is obtained in accordance with the first sawtooth wave signal, and a second differential signal is obtained in accordance with the second sawtooth wave signal. The level of a tracking error sum signal is shifted to obtain a level-shifted signal, so that a polarity signal is obtained. The first differential signal is selected when the polarity signal is positive, and the second differential signal is selected when the polarity signal is negative and, thus, a velocity signal showing the velocity of the beam spot with a high accuracy may be obtained.

Thus, it becomes possible to smoothly and quickly move the optical head, and further it becomes possible to accurately locate the optical head.
