ABSTRACT-This paper aims to develop a new design of a bentleg (BL) plow and to determine its performance as compared to the conventional one using finite element approach. The difference between the modified and conventional BL plows is the direction of angle between the projection of cutting blade on horizontal plane normal to plow shank and the line perpendicular to the plow shank in the same...
G protein-coupled receptor 154 (GPR154) is a recently discovered asthma susceptibility gene upregulated in the airways of asthma patients. We previously observed increased pulmonary mRNA expression of the murine ortholog Gpr154 in a mouse model of ovalbumin (OVA)-induced inflammation. However, the expression profile of GPR154 in leukocytes and the cellular functions of the receptor and its endo...
The Epstein-Barr virus BamHI F promoter (Fp) was previously identified as the putative EBNA 1 gene promoter in group 1 Burkitt's lymphoma (BL) cell lines. Fp has also been shown to be activated in Epstein-Barr virus-positive B-cell lines following induction of the viral productive cycle (A. L. Lear, M. Rowe, M. G. Kurilla, S. Lee, S. Henderson, E. Kieff, and A. B. Rickinson, J. Virol. 66:7461-7...
PG1553+113 is a known BL Lac object, newly detected in the GeV-TeV energy range by H.E.S.S and MAGIC. The redshift of this source is unknown and a lower limit of z > 0.09 was recently estimated. The very high energy (VHE) spectrum of PG1553+113 is attenuated due to the absorption by the low energy photon field of the extragalactic background light (EBL). Here we correct the combined H.E.S.S and...
We present multiwavelength observations of the BL Lacertae object Markarian 501 (Mrk 501) in 1997 between April 8 and April 19. Evidence of correlated variability is seen in very high energy (VHE; E * 350 GeV) gray observations taken with the Whipple Observatory g-ray telescope, data from the Oriented Scintillation Spectrometer Experiment of the Compton Gamma Ray Observatory, and quick-look res...
Detection of Very-High Energy Gamma-Rays from the BL Lac Object PG 1553+113 with the MAGIC Telescope
The MAGIC telescope has observed very-high energy gamma-ray emission from the BL Lac object PG 1553+113 in 2005 and 2006 at an overall significance is 8.8σ . The light curve shows no significant flux variations on a daily timescale. The flux level during 2005 was, however, significantly higher as compared to 2006. The differential energy spectrum between ∼90 GeV and 500 GeV is well described by...

We analytically calculate some thermodynamic quantities of an ideal g-on gas obeying generalized exclusion statistics. We show that the specific heat of a g-on gas (g 6= 0) vanishes linearly in any dimension as T → 0 when the particle number is conserved and exhibits an interesting dual symmetry that relates the particle-statistics at g to the hole-statistics at 1/g at low temperatures. We deri...
in this thesis we will present three topics. we define approximate fixed points in fuzzy normed spaces. also we obtain some necessary and sufficient conditions on the existence of? -fixed points for ? > 0. at the continue some results about approximate fixed points for a class of non-expansive maps on g-metric spaces are obtained and we define approximate fixed points in partial metric spa...
Context. The redshift of PG 1553+11, a bright BL Lac object (V ∼ 14), is still unknown. It has been recently observed in the TeV band, a fact that offers an upper limit for the redshift z < 0.4. Aims. We intend to provide a lower limit for the distance of the object. Methods. We used a χ2 procedure to constrain the apparent magnitude of the host galaxy in archived HST images. Supposing that the...
