Heterogeneous nuclear ribonucleoprotein D0 (hnRNP D0) is an abundant, ubiquitous protein that binds RNA and DNA sequences specifically, and has been implicated in the transcriptional regulation of the human complement receptor 2 gene. We found that in vivo expression of hnRNP D0-GAL4 fusion proteins increased the transcriptional activity of a GAL4-driven reporter gene, providing direct proof th...

Let D be an integral domain. A multiplicative set S of D is an almost splitting set if for each 0 6= d ∈ D, there exists an n = n(d) with dn = st where s ∈ S and t is v-coprime to each element of S. An integral domain D is an almost GCD (AGCD) domain if for every x, y ∈ D, there exists a positive integer n = n(x, y) such that xnD ∩ ynD is a principal ideal. We prove that the polynomial ring D[X...

In this paper, we devote to investigation of the existence of positive solutions for the boundary value problem of nonlinear fractional differential equations { D0+u(t)+ f (t,u(t)) = 0, 0 < t < 1, u(0) = u′(0) = · · ·u(n−2)(0) = D0+u(1), where D0+ , D β 0+ are the standard Riemann-Liouville fractional derivative, n− 1 < α n , n−2 β n−1 , n 3 . By means of constructing an exact cone of the Banac...

D0-branes on a D2-brane with a constant background B-field are unstable due to the presence of a tachyonic mode and expected to dissolve into the D2-brane to formulate a constant D0-charge density. In this paper we study such a dissolution process in terms of a noncommutative gauge theory. Our results show that the localized D0-brane spreads out over all of space on the D2-brane as the tachyon ...

The applicability of a novel gold–epoxysurface nanocomposite for surface-enhanced Raman scattering (SERS) is investigated. consists ellipsoidal nanoparticles in hexagonal arrangement, where the average particle diameter (D0) and interparticle gap (D) can be controlled 0.15–1.00 (D/D0) range on large surface area (several cm 2). Numerical simulations were used to estimate SERS enhancement factor...

where ∂i = ∂/∂x i and D = ∪ 0≤t≤T {t}×Dt, Dt ⊂ R. Here V k = δvi = vk and we use the summation convention over repeated upper and lower indices. The velocity vector field of the fluid is V , p is the pressure and Dt is the domain the fluid occupies at time t. We also require boundary conditions on the free boundary ∂D; p = 0, on ∂D, (1.3) (∂t + V ∂k)|∂D ∈ T (∂D), (1.4) Condition (1.3) says that...

We (re)examine CP violation in the decays B d → DKS, where D represents D, D0, or one of their excited states. The quantity sin(2β + γ) can be extracted from the time-dependent rates for B d(t) → D̄KS and B d(t) → DKS, where the D decays to Dπ. If one considers a non-CP-eigenstate hadronic final state to which both D0 and D can decay (e.g. Kπ), then one can obtain two of the angles of the unitar...

Under typical physical conditions, the solution of the capillarity equation for a tube of circular section D will always exceed over D the solution obtained for a concentric tube of the same material and larger radius. We address here a question raised by M. Miranda, as to whether a solution over a general domain D0 will exceed, over that section, the solution over any domain D1 strictly contai...

We have extended the utility of NMR as a technique to probe porous media structure over length scales of ;100–2000 mm by using the spin 1/2 noble gas Xe imbibed into the system’s pore space. Such length scales are much greater than can be probed with NMR diffusion studies of water-saturated porous media. We utilized Pulsed Gradient Spin Echo NMR measurements of the time-dependent diffusion coef...
