AKR mice, which produce high titers of ecotropic virus, were crossed with NZB mice, which produce titers of xenotropic virus. Spleen, marrow, and lymph node cells of the F1 hybrid produced high titers of ecotropic and xenotropic viruses. However, expression of ecotropic virus by both thymus cells and peripheral T cells of the F1 was severely restricted. Despite simultaneous expression of ecotor...

F1-ATPase is a rotary motor protein driven by ATP hydrolysis. The rotary motion of F1-ATPase is tightly coupled to catalysis, in which the catalytic sites strictly obey the reaction sequences at the resolution of elementary reaction steps. This fine coordination of the reaction scheme is thought to be important to achieve extremely high chemomechanical coupling efficiency and reversibility, whi...

The implications of the f1(1285) − f1(1420) mixing for the K1(3P1) − K1(1P1) mixing angle is investigated. Based on the f1(1285)− f1(1420) mixing angle ∼ 50 suggested from the analysis for a substantial body of data concerning the f1(1420) and f1(1285), the masses of the K1( 3P1) and K1( 1P1) are determined to be ∼ 1307.35± 0.63 MeV and 1370.03± 9.69 MeV, respectively, which therefore suggests ...

Let k be an arbitrary field, and C be a curve in A defined parametrically by x1 = f1(t), . . . , xn = fn(t), where f1, . . . , fn ∈ k[t]. A necessary and sufficient condition for the two function fields k(t) and k(f1, . . . , fn) to be same is developed in terms of zero-dimensionality of a derived ideal in the bivariate polynomial ring k[s, t]. Since zerodimensionality of such an ideal can be r...

Let AG(n,Fq) be the n-dimensional affine space over the finite field Fq. For 0 ≤ m ≤ n − 1, define a graph G whose vertex set is the set of all m-flats of AG(n,Fq), such that two vertices F1 and F2 are adjacent if dim(F1∨F2) = m+1, where F1∨F2 is the minimum flat containing both F1 and F2. Let ASG(2ν,Fq) be the 2ν-dimensional affine-symplectic space over Fq. Define a graph S (ν) whose vertex se...

Formula One (F1) drivers are amongst the most highly skilled drivers in the world, but not every F1 driver is destined to be a F1 World Champion. Discovering new talent or refreshing strategies are long-term investments for all competitive F1 teams. The F1 world and teams invest vast amounts in developing high-fidelity simulators; however, driving games have seldom been associated with uncoveri...
