Many error correcting codes are known to be self-dual. Hence the MacWilliams identities put a considerable restriction on the possible weight distribution of such a code. We show that this restriction, for codes over GF(2) and GF(3), is that the weight polynomial must lie in an explicitly described free polynomial ring. To extend these results (in part) to self-dual codes over larger fields, we...

The TNFR superfamily members 4-1BB (CD137) and OX40 (CD134) are costimulatory molecules that potently boost CD8 and CD4 T cell responses. Concomitant therapeutic administration of agonist anti-CD137 and -CD134 mAbs mediates rejection of established tumors and fosters powerful CD8 T cell responses. To reveal the mechanism, the role of CD137 expression by specific CD8 T cells was determined to be...

OBJECTIVE Compared with HIV monoinfection, HIV dual infection has been associated with decreased CD4 T-cell counts and increased viral loads. The same markers are also associated with the development of HIV-associated neurocognitive disorder (HAND), which continues to be a prevalent problem in the era of combination antiretroviral therapy (ART). We sought to determine the relationship between d...

In this paper, we will give the subconvexity bounds for self-dual GL(3) L-functions in the t aspect as well as subconvexity bounds for self-dual GL(3) × GL(2) L-functions in the GL(2) spectral aspect.

BACKGROUND The purpose of this study was to establish the feasibility of three-dimensional (3D) balanced steady-state-free-precession (bSSFP) myocardial perfusion cardiovascular magnetic resonance (CMR) at 3T using local RF shimming with dual-source RF transmission, and to compare it with spoiled gradient echo (TGRE) acquisition. METHODS Dynamic contrast-enhanced 3D bSSFP perfusion imaging wa...

To determine whether bone mineral density measurement using the Calscan successfully predicts the actual bone mineral density, as measured by dual-energy X-ray absorptiometry. We included all patients≥65 years with a hip fracture screened on osteoporosis by both dual-energy X-ray absorptiometry and the Calscan during the period April 2008 to April 2011. The bone mineral density was expressed as...

We study the fermionic T-duality symmetry of integrable Green-Schwarz sigma models on AdS backgrounds. We show that the sigma model on AdS5 × S1 background is self-dual under fermionic T-duality. We also construct new integrable sigma models on AdS2 ×CPn. These backgrounds could be realized as supercosets of SU supergroups for arbitrary n, but could also be realized as supercosets of OSp superg...

In this paper, we introduce the concept of $g$-dual frames for Hilbert $C^{*}$-modules, and then the properties and stability results of $g$-dual frames  are given.  A characterization of $g$-dual frames, approximately dual frames and dual frames of a given frame is established. We also give some examples to show that the characterization of $g$-dual frames for Riesz bases in Hilbert spaces is ...
