Measurements of the angular distributions of target and double-spin asymmetries for the Δ+(1232) in the exclusive channel →p(→e,e′p)π0 obtained at the Jefferson Lab in the Q2 range from 0.5 to 1.5GeV2/c2 are presented. Results of the asymmetries are compared with the unitary isobar model [D. Drechsel et al., Nucl. Phys. A645, 145 (1999)], dynamical models [T. Sato and T. S. Lee, Phys. Rev. C 54, 2
Specific interactions between the carboxylic acid moiety and the monovalent salts CsCl, NaCl, and LiCl, have been investigated in Langmuir monolayers using vibrational sum frequency spectroscopy (VSFS) and complemented with coarse grained and all-atom molecular dynamics simulations. By exploiting VSFS's intrinsic surface specificity, an emphasis was made on targeting headgroup vibrations of both i
The galactomannan utilization locus (BoManPUL) of the human gut bacterium Bacteroides ovatus encodes BoMan26B, a cell-surface– exposed endomannanase whose functional and structural features have been unclear. Our study now places BoMan26B in context with related enzymes and reveals the structural basis for its specificity. BoMan26B prefers longer substrates and is less restricted by galactose side
We report the results of a new measurement of spin structure functions of the deuteron in the region of moderate momentum transfer [Q2=0.27–1.3(GeV/c)2] and final hadronic state mass in the nucleon resonance region (W=1.08–2.0GeV). We scattered a 2.5 GeV polarized continuous electron beam at Jefferson Lab off a dynamically polarized cryogenic solid state target (15ND3) and detected the scattered e
Models of baryon structure predict a small quadrupole deformation of the nucleon due to residual tensor forces between quarks or distortions from the pion cloud. Sensitivity to quark versus pion degrees of freedom occurs through the Q2 dependence of the magnetic (M1+), electric (E1+), and scalar (S1+) multipoles in the γ∗p→Δ+→pπ0 transition. We report new experimental values for the ratios E1+/M1+
Upshift - a first version of a piano piece in the project "The Music in the Piano", which is a collaboration with pianist and teacher Eva Lundgren at Malmö Academy of Music.
We study the solvability for a system of pseudodifferential operators. We will assume that the systems is of principal type, i.e., the principal symbol vanishes of first order on the kernel, and that the eigenvalue close to zero has constant multiplicity. We prove that local solvability is to condition (PSI) on the eigenvalues as in the scalar case. This condition rules out any sign changes from -
Till Elise (For Elise) - a piano piece in the project "The Music in the Piano", which is a collaboration with pianist and teacher Eva Lundgren at Malmö Academy of Music. This piece is a "flirt" with one of the most famous piano pieces in history.
The High-Resolution Spectrometers in Hall A at Jefferson Laboratory have been instrumented with state-of-the-art Vertical Drift Chambers designed and constructed by the Nuclear Interactions Group at MITLNS in conjunction with the Physics Division at Jefferson Lab. These chambers rely on a unique, high cell-density design made possible by the absence of field-shaping wires. Each chamber has an inhe
We report the first results of the beam-spin asymmetry measured in the reaction →ep→epγ at a beam energy of 4.25 GeV. A large asymmetry with a sinφ modulation is observed, as predicted for the interference term of deeply virtual compton scattering (DVCS) and the Bethe-Heitler process. The amplitude of this modulation is α=0.202±0.028. In leading-order and leading-twist perturbative QCD, the α is d
Det här kapitlet handlar om egyptiska kvinnorättsaktivister och deras arbete med att påverka Egyptens nya konstitution efter revolutionen 2011. Aktivisternas mål var att stärka kvinnors konstitutionella rättigheter och det försökte man nå genom att etablera en arbetsgrupp som på nära håll följde konstitutionsprocessen. I kapitlet analyseras dessa aktivisters kritik av utkasten till konstitutionen
