Hard exclusive processes give us unique possibility to study internal structure of hadrons. The theoretical description of exclusive processes is based on the QCD factorization approach [1–6]. Scattering amplitudes (decay amplitudes) in this approach are given by convolution of the coefficient function which can be calculated perturbatively with nonpertubative functions – the distribution ampli...

The VP40 matrix protein of Marburg virus (MARV) has been shown to be the driving force behind MARV budding, a process in which the PPPY L-domain motif of VP40 plays a critical role. Here, we report that Vps4B and Nedd4.1 play critical roles in MARV VP40-mediated budding. We showed that unidentified activities of the Nedd4.1 HECT domain, along with its E3 ubiquitin ligase activity, may be requir...

The hyper-Wiener index WW of a graph G is defined as WW(G) = (summation operator d (u, v)(2) + summation operator d (u, v))/2, where d (u, v) denotes the distance between the vertices u and v in the graph G and the summations run over all (unordered) pairs of vertices of G. We consider three different methods for calculating the hyper-Wiener index of molecular graphs: the cut method, the method...

The WWOX gene is a recently cloned tumor suppressor gene that spans the FRA16D fragile region. Wwox protein contains two WW domains that are generally known to mediate protein-protein interaction. Here we show that Wwox physically interacts via its first WW domain with the p53 homolog, p73. The tyrosine kinase, Src, phosphorylates Wwox at tyrosine 33 in the first WW domain and enhances its bind...

The possibility to observe a Higgs boson having a mass between 300 and 600 GeV and to measure its couplings to vector bosons and top quark with CMS at the LHC is studied. The different signatures: H → ZZ → l+l−l+l− H → ZZ → l+l−νν̄ H → ZZ → l+l−qq̄ H → ZZ → νν̄qq̄ H → WW → lνlν H → WW → lνqq are analyzed. The possibility to separate the Higgs events produced through weak boson fusion (qq → qqH) fro...

Weerts This Letter reports a measurement of the WW production cross section in √ s = 7 TeV pp collisions using data corresponding to an integrated luminosity of 1.02 fb−1 collected with the ATLAS detector. Using leptonic decays of oppositely charged W bosons,...

iSPOT (http://cbm.bio.uniroma2.it/ispot) is a web tool developed to infer the recognition specificity of protein module families; it is based on the SPOT procedure that utilizes information from position-specific contacts, derived from the available domain/ligand complexes of known structure, and experimental interaction data to build a database of residue-residue contact frequencies. iSPOT is ...

A method to embed models of strong WW scattering in unitary gauge amplitudes is presented that eliminates the need for the effective W approximation (EWA) in the computation of cross sections at high energy colliders. The cross sections obtained from the U-gauge amplitudes include the distributions of the final state fermions in ff → ffWW , which cannot be obtained from the EWA. Since the U-gau...

In this study, we have identified a novel Nedd4-like ubiquitin ligase, BUL1, as the host factor involved in budding of type D retrovirus Mason-Pfizer monkey virus (M-PMV). Overexpression of BUL1 enhanced virus particle release, while a BUL1 mutant in which a W to G substitution was introduced into a WW domain, W791G, lost the ability to bind to the viral Gag protein and abolished its ability to...

To compare the activity of lower extremity muscles during land walking (LW), water walking (WW), and deep-water running (DWR), 9 healthy young subjects were tested at self-selected low, moderate, and high intensities for 8 sec with two repetitions. Surface EMG electrodes were placed on the tibialis anterior (TA), soleus (SOL), medial gastrocnemius (GAS), rectus femoris (RF), and biceps femoris ...
