Summary Recent studies of the spinal cord and cerebellum have highlighted importance atrophy in development neurological impairment multiple sclerosis. We therefore developed a technique to quantify volume another area commonly involved pathologically sclerosis: cerebral white matter. The we describe extracts brain from skull on four contiguous 5 mm periventricular slices using an algorithm integrated image analysis package, quantifies their volume. Intra-observer scan-rescan reproducibility...
We report on a precision measurement of the neutron spin structure function ${g}_{1}^{n}$ using deep inelastic scattering polarized electrons by ${}^{3}\mathrm{He}$. For kinematic range $0.014<x<0.7$ and $1<{Q}^{2}<17(\mathrm{GeV}/c{)}^{2}$, we obtain $\ensuremath{\int}{0.014}^{0.7}{g}_{1}^{n}(x)dx\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}\ensuremath{-}0.036\ifmmode\pm\else\textpm\fi{}0.004(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.005(\mathrm{syst})$ at an average...
We present the final results of spin asymmetries A1 and structure functions g1 proton deuteron in kinematic range 0.0008<x<0.7 0.2<Q2<100GeV2. For determination A1, addition to usual method which employs inclusive scattering events includes a large radiative background at low x, we use new minimizes by selecting with least one hadron as well muon state. find that this gives smaller errors for x<0.02, so it is combined provide optimal set results.Received 18 May...
Previous studies have shown only modest correlation between multiple sclerosis (MS) lesions on MRI and clinical disability.To investigate the relationship proton density/T2-weighted (T2) burden of disease (BOD) quantitatively measured scans determinants including disability.Using Sylvia Lawry Centre for Multiple Sclerosis Research (SLCMSR) database, authors studied baseline T2 BOD data from a pooled subsample 1,312 placebo MS patients 11 randomized controlled trials. Univariate comparisons...

We have investigated ${\ensuremath{\pi}}^{\ensuremath{-}}p$ interactions from $1.5 \mathrm{to} 4.2 \frac{\mathrm{BeV}}{c}$ in the Lawrence Radiation Laboratory's 72-in. hydrogen bubble chamber. This report describes procedures for identifying and analyzing reactions involving strange-particle production, results obtained on three- more-body final states. The analysis is based 890 000 photographs, which 50 events were found. Cross sections constrained states are presented as a function of...

We present a new measurement of the spin-dependent structure function g1d deuteron in deep inelastic scattering 190 GeV polarised muons on deuterons, kinematic range 0.003 < x 0.7 and 1 GeV2 Q2 60 GeV2. This is found to be negative at small x. The first moment Γ1d=∫01g1ddx evaluated Q02 = 10 0.034 ± 0.009 (stat.) 0.006 (syst.). value below Ellis-Jaffe sum rule prediction by three standard deviations. Using our earlier determination Γ1p, we obtain Γ1p − Γ1n 0.199 0.038 which agrees with Bjorken rule.
We present a measurement of semi-inclusive spin asymmetries for positively and negatively charged hadrons from deep inelastic scattering polarised muons on protons deuterons in the range 0.003<x<0.7 Q2>1 GeV2.

From these inclusive we determine quark distributions valence quarks non-strange sea at Q2=10 The u distribution, Δuv(x), is positive polarisation increases x. d...
<b>Background:</b> In patients with clinically isolated syndromes (CIS) suggestive of multiple sclerosis (MS), the extent brain magnetic resonance imaging (MRI) lesion load influences probability and time to development definite MS. Cerebral atrophy is recognised in established MS, but its onset whether, early disease, it related MRI or clinical outcome less certain. <b>Objectives:</b> This study investigated ventricular enlargement over one year CIS explored relation outcome....
