The relativistic Vlasov-Maxwell system of plasma physics is considered with initial data on a past light cone. This characteristic initial value problem arises in a natural way as a mathematical framework to study the existence of solutions isolated from incoming radiation. Conservation laws and a priori estimates of smooth solutions are first derived in a formal way. In the spherically symmetr...

BACKGROUND Sex difference is an established risk factor for hematopoietic stem cell transplantation (HSCT)-related complications like graft versus host disease (GVHD). CD8pos cytotoxic T cells specific for Y chromosome-encoded minor Histocompatibility antigens (HY) play an important role therein. Prior to HSC donation, female donors may encounter HY antigens through fetomaternal or transmaterna...

We undertook a comparative study of the effects of the hormone hydrocortisone (Hy) on C6 glioma cells grown in monolayer and in suspension in cultures. We found Hy reversibly renders C6 cells anchorage- and serum-dependent for their growth. In monolayer cultures, Hy was found to inhibit cell cycle traversing exclusively at G1 phase. In agarose suspension, Hy was found to block colony developmen...

Three human IFN-alpha hybrids, HY-1 [IFN-alpha21a(1-75)/alpha2c(76-165)], HY-2 [IFN-alpha21a(1-95)/alpha2c(96-165)], and HY-3 [IFN-alpha2c(1-95)/alpha21a(96-166)], were constructed, cloned, and expressed. The hybrids had comparable specific antiviral activities on Madin-Darby bovine kidney (MDBK) cells but exhibited very different antiproliferative and binding properties on human Daudi and WISH...

A balanced generalized de Bruijn sequence with parameters (n,l,k) is a cyclic of n bits such that (a) the number 0's equals 1's, and (b) each substring length l occurs at most k times. We determine necessary sufficient conditions on n,l, for existence sequence.

Renewable energy sources are alternative energy source, can bring new challenges when it is connected to the power grid. Generated power from wind energy system is always fluctuating due to the fluctuations in the wind. According to the guidelines specified in IEC61400 standard (International Electro-technical Commission) provides some norms and measurements. The performance of the wind turbine...

Photolysis into the longest wavelength absorption band of 2-tert-butyl-2,3-diazabicyclo[2.2.2]oct-3-yl hydrazine (Hy) substituted naphthalenes causes aryl group reduction electron transfer to give (+)Hy-Ar(-). Electrooptical absorption measurements characterize the charge separation properties from these bands. Emission studies demonstrate that the separation between absorption and emission max...
