We present here two epochs of Space VLBI Observations at 18 cm of the BL-Lac type object Mkn 501. Thanks to the high resolution of these new data we have found that the inner jet is centrally brightened at its beginning but becomes extended and limb brightened at ∼ 8 mas from the core. Moreover a comparison between the two epochs shows the presence of a proper motion with apparent velocity = 6....

This is a closed-book exam. The exam lasts for 180 minutes. Please write clearly and legibly. Be especially careful in the definition of the game, the payoff function and the equilibrium notions. The allocated points are also a good indicator for your time budget. Please record the answer for each question in a separate bluebook.

We identified the mutations causing factor XIII A subunit deficiency in two families. Two distinct mutations were identified in the S family: the nonsense mutation Tyr 441-->stop in exon 11, inherited through the paternal line, and the missense mutation Asn 60-->Lys in exon 3, inherited through the maternal line. Two members of the J family were heterozygous for the previously described type 3 ...

Introduction Long non-coding RNA LINC00641 has been reported to regulate tumor progression in several cancers. However, the expression and function of hepatocellular carcinoma (HCC) is still unclear. Material methods In this study, we measured 79 pairs HCC adjacent normal liver tissues. The clinical significance was explored. We also investigated proliferation invasion. Results observed that si...

The number of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) in synapses determines synaptic strength. AMPAR expression can be regulated locally in dendrites by synaptic activity. The mechanisms of activity-dependent local regulation of AMPAR expression, however, remain unclear. Here, we tested whether microRNAs (miRNAs) are involved in N-methyl-D-aspartate (NMDA) recep...

Several high-frequency peaked BL Lac objects such as Mrk 501 are strong TeV emitters. However, a significant fraction of the TeV gamma rays emitted are likely to be absorbed in interactions with the diffuse IR background, yielding electron-positron pairs. Hence, the observed TeV spectrum must be steeper than the intrinsic one. Using the recently derived intrinsic γ-ray spectrum of Mrk 501 durin...
