Mice lacking epidermal Langerhans cells (LC) develop exaggerated contact-hypersensitivity (CHS) responses due to the absence of LC during sensitization/initiation. Examination of T cell responses reveals that the absence of LC leads to increased numbers of hapten-specific CD4 and CD8 T cells but does not alter cytokine expression or development of T regulatory cells. CHS responses and Ag-specif...

The asymptotic properties of inhomogeneous products in the max-plus algebra context have been investigated. In particular, for products involving matrices with the same unique critical circuit, we have obtained some sufficiency conditions under which the rank of the final product matrix is less than or equal to the length of the critical circuit of the matrices in the product. For a product com...

This paper proposes a microstrip patch antenna for 2.45 GHz Industrial Scientific Medical (ISM) band Wireless Body Area Network (WBAN) applications. To enhance the front-to-back ratio (F/B) and specific absorption rate (SAR), an electrically coupled LC resonator is introduced. The overall dimensions of the proposed antenna are 54 mm × 45 mm × 2.4 mm and it has a gain of over 1 dBi for the entir...

Bulbospinal noradrenergic pathways are shown to have an important role in descending inhibition of pain sensation. Locus ceruleus (LC), as a rich noradrenergic nucleus in the brain stem which has projections into the dorsal horn of the spinal cord, was evaluated for antinociceptive activity by using tonic and phasic pain models in the rat. LC-lesioned rats demonstrated moderate increase in ...

We discuss progress and issues relevant to the design of a highly segmented silicontungsten electromagnetic calorimeter. Our design features a complete readout chip which is integrated onto each detector wafer, thus reducing the effective channel count by a factor of about 1000. We apply this design to the SD detector of the American LC Physics Group, but some elements could be applicable elsew...

Comprehensive two-dimensional liquid chromatography (LC×LC) using the Agilent 1290 Infi nity 2D-LC Solution with DAD and MS detection is applied for the analysis of citrus oils. The developed method uses normal phase liquid chromatography in the fi rst dimension and reversed-phase liquid chromatography in the second dimension. This combination provides good orthogonality and is valuable for pro...

Screen magnification is an important means to support visually impaired people when working with computers. Many improvements have been made on appropriate software. But unfortunately, in the last years, those improvements where mainly in realization detail. A number of problems remain, that, to our minds, need conceptual rethinking. In this paper, we present a new concept for magnification sof...
