The ability of immune-based cancer therapies to elicit beneficial CD8(+) CTLs is limited by tolerance pathways that inactivate tumor-specific CD4 Th cells. A strategy to bypass this problem is to engage tumor-unrelated CD4 Th cells. Thus, CD4 T cells, regardless of their specificity per se, can boost CD8(+) CTL priming as long as the cognate epitopes are linked via presentation on the same dend...

An alternative technique for finding small roots of univaxiate modular equations is described. This approach is then compared with that taken in (Coppersmith, 1996), which links the concept of the dual lattice (see (Cassels, 1971)) to the LLL algorithm (see (Lenstra et al., 1982)). Timing results comparing both algorithms are given, and practical considerations axe discussed. This work has dire...

We study vector bundles on flag varieties over an algebraically closed field $k$. In the first part, we suppose $G=G_k(d,n)$ $(2\le d\leq n-d)$ to be Grassmannian manifold parameterizing linear subspaces of dimension $d$ in $k^n$, where $k$ is characteristic $p>0$. Let $E$ a uniform bundle $G$ rank $r\le d$. show that either direct sum line or twist pull back universal $H_d$ its dual $H_d^{\vee...

we prove the generalized hyers--ulam stability  of n--th order linear differential equation of the form $y^{(n)}+p_{1}(x)y^{(n-1)}+ cdots+p_{n-1}(x)y^{prime}+p_{n}(x)y=f(x)$, with condition that there exists a non--zero solution of corresponding homogeneous equation. our main results extend and improve the corresponding results obtained by many authors.

For a convex body C in a Euclidean vector space X of dimension n (≥ 2), we define two sub-arithmetic monotonic sequences {σC,k}k≥1 and {σo C,k}k≥1 of functions on the interior of C. The k-th members are “mean Minkowski measures in dimension k” which are pointwise dual: σo C,k(O) = σCO,k(O), where O ∈ int C, and CO is the dual (polar) of C with respect to O. They are measures of (anti-)symmetry ...

Recently, a one-parameter deformation of the Maldacena-Núñez background was constructed in hep-th/0505100. According to the Lunin-Maldacena conjecture, the background is dual to pure N = 1 SYM in the IR coupled to a KK sector whose dynamics is altered by a dipole deformation that is proportional to the deformation parameter γ. Thus, the deformation serves to identify the aspects of the gravity ...
