Automated nose fairing design - Honeycomb sandwich construction
Computer program for near optimum structural designs of ring stiffened honeycomb sandwich nose fairing
Searching a biomedical database from Bulgaria : the ABS database
The University of Sofia, Bulgaria, disseminates local biomedical literature (1994 to present) through a free online database, ABS. We systematically searched ABS to identify citations to controlled trials and find what proportion of these studies are to be found on MEDLINE.
We searched using Bulgarian and English phrases; manually selected citations of controlled trials and sought these citations on MEDLINE. Using the two languages we found a total of 628 unique citations, of which 47 of which seem to be relevant controlled trials (precision 7.48%, 13% of ABS citations were found on MEDLINE). The trials in ABS commonly focused on evaluation of care for people with cardiovascular or urological problems

Non-Hodgkin and Hodgkin Lymphomas Select for Overexpression of BCLW.
Purpose: B-cell lymphomas must acquire resistance to apoptosis during their development. We recently discovered BCLW, an antiapoptotic BCL2 family member thought only to contribute to spermatogenesis, was overexpressed in diffuse large B-cell lymphoma (DLBCL) and Burkitt lymphoma. To gain insight into the contribution of BCLW to B-cell lymphomas and its potential to confer resistance to BCL2 inhibitors, we investigated the expression of BCLW and the other antiapoptotic BCL2 family members in six different B-cell lymphomas. Experimental Design: We performed a large-scale gene expression analysis of datasets comprising approximately 2,300 lymphoma patient samples, including non-Hodgkin and Hodgkin lymphomas as well as indolent and aggressive lymphomas. Data were validated experimentally with qRT-PCR and IHC. Results: We report BCLW is significantly overexpressed in aggressive and indolent lymphomas, including DLBCL, Burkitt, follicular, mantle cell, marginal zone, and Hodgkin lymphomas. Notably, BCLW was preferentially overexpressed over that of BCL2 and negatively correlated with BCL2 in specific lymphomas. Unexpectedly, BCLW was overexpressed as frequently as BCL2 in follicular lymphoma. Evaluation of all five antiapoptotic BCL2 family members in six types of B-cell lymphoma revealed that BCL2, BCLW, and BCLX were consistently overexpressed, whereas MCL1 and A1 were not. In addition, individual lymphomas frequently overexpressed more than one antiapoptotic BCL2 family member. Conclusions: Our comprehensive analysis indicates B-cell lymphomas commonly select for BCLW overexpression in combination with or instead of other antiapoptotic BCL2 family members. Our results suggest BCLW may be equally as important in lymphomagenesis as BCL2 and that targeting BCLW in lymphomas should be considered. ©2017 AACR
Thermalization of gluons at RHIC: Dependence on initial conditions
We investigate how thermalization of gluons depends on the initial conditions
assumed in ultrarelativistic heavy ion collisions at RHIC. The study is based
on simulations employing the pQCD inspired parton cascade solving the Boltzmann
equation for gluons. We consider independently produced minijets with GeV and a color glass condensate as possible initial
conditions for the freed gluons. It turns out that full kinetic equilibrium is
achieved slightly sooner in denser system and its timescale tends to saturate.
Compared with the kinetic equilibration we find a stronger dependence of
chemical equilibration on the initial conditions.Comment: 8 pages, 4 figures; Contribution to Proceedings of the Quark-Gluon

Resonance decay effects on anisotropy parameters
We present the elliptic flow of pions produced from resonance decays.
The transverse momentum spectra of the parent particles are taken from
thermal model fits and their are fit under the assumption that they
follow number-of-constituent-quark (NCQ) scaling expected from
quark-coalescence models. The of pions from resonance particle decays is
found to be similar to the measured pion . We also propose the measurement
of electron as a means to extract open-charm and investigate
whether a thermalized system of quarks and gluons (a quark-gluon plasma) is
created in collisions of Au nuclei at RHIC.Comment: 5 pages, 4 figure
Experimental data on the single spin asymmetry and their interpretations by the chromo-magnetic string model
An attempt is made to interpret the various existing experimental data on the
single spin asymmetries in inclusive pion production by the polarized proton
and antiproton beams. As the basis of analysis the chromo-magnetic string model
is used. A whole measured kinematic region is covered. The successes and fails
of such approach are outlined. The possible improvements of model are
discussed.Comment: 17 pages, 3 figure
