Differential cross sections for electron scattering from hydrogen and deuterium in the deep-inelastic region show that neutron section is significantly smaller than proton over a large part of kinematic studied. Although $\ensuremath{\nu}{{W}_{2}}^{d}$ differs magnitude $\ensuremath{\nu}{{W}_{2}}^{p}$, it exhibits similar scaling behavior.
Importance Numerous studies show that early palliative care improves quality of life and other key outcomes in patients with advanced cancer their caregivers, although most lack access to this evidence-based model care. Objective To evaluate whether delivering via secure video vs in-person visits has an equivalent effect on non–small cell lung (NSCLC).

Electron-proton elastic-scattering cross sections have been measured at the Stanford Linear Accelerator Center for four-momentum transfers squared ${q}^{ 2}$ from 1.0 to 25.0 ${(\frac{\mathrm{GeV}}{c})}^{2}$. The electric (${G}_{{E}_{p}}$) and magnetic (${G}_{{M}_{p}}$) form factors of proton were not separated, since angular distributions each 2}$. However, values ${G}_{{M}_{p}}$ derived assuming various relations between ${G}_{{E}_{p}}$ ${G}_{{M}_{p}}$. Several theoretical models behavior...
Measurements of the ratio ($R$) positron-proton and electron-proton elastic-scattering cross sections have been made, with square four-momentum transfer (${q}^{2}$) equal to 0.20, 0.69, 0.73, 1.54, 2.44, 3.27, 3.79, 5.00 ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. The measurements, after radiative corrections, are consistent $R=1$, standard errors ranging from \ifmmode\pm\else\textpm\fi{}0.016 \ifmmode\pm\else\textpm\fi{}0.123. results give limits for size two-photon effects.

ABSTRACT A novel, in vitro bioassay for detection of the botulinum type B neurotoxin a range media was developed. The assay is amplified by enzymic activity neurotoxin’s light chain and includes following three stages: first, small, monoclonal antibody-based immunoaffinity column captures toxin; second, peptide substrate cleaved using endopeptidase neurotoxin; finally, modified enzyme-linked immunoassay system detects cleavage products. highly specific capable detecting toxin at...
A total synthesis of (+)-peloruside has been successfully achieved. The strategy was highlighted by a late stage aldol coupling two complex fragments followed an intramolecular hemi-ketal cyclization, MOM group participated epoxide ring fragmentation reaction, and highly selective methylation. This convergent route allows access to rationally designed analogues.

We have searched for an asymmetry in the inelastic scattering of electrons from a polarized proton target region resonance excitation, at values four-momentum transfer squared 0.4, 0.6, and 1.0 ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. Data were also taken using incident positron beam order to distinguish any possible effect time-reversal invariance violation that due higher-order (${\ensuremath{\alpha}}^{3}$) contributions scattering. No sizable was found.
