To prove feasibility of proton chemical shift imaging ((1)H CSI) during stereotactic procedure, authors performed (1)H CSI in combination with a stereotactic headframe and selected targets according to local metabolic information, evaluated the pathologic results. The (1)H CSI directed stereotactic biopsy was performed in four patients. (1)H CSI and conventional Gd-enhancement stereotactic MRI ...

Raman activities and degrees of depolarization are reported for 14 complexes involving methanol, ethanol and water using the MP2/ aug-cc-pVDZ model. For ethanol both trans and gauche isomers are considered. The red-shifts of the OH stretching and the blue shifts of the bending sCO–OH mode were analyzed for the proton-donor molecules upon hydrogen bond. The shift of the mCO stretching mode of th...

The hadron collider studied in the future circular collider (FCC) project could operate with protons and lead ions in similar operation modes as the LHC. In this paper the potential performances in lead-lead, proton-lead, and proton-proton collisions are investigated. Based on average lattice parameters, the strengths of intrabeam scattering and radiation damping are evaluated and their effect ...

A large entropy of proton solvation was used for thermoelectric conversion. [Ru(Him)6] complex produces 3.7 mV at a temperature difference 1 K. This ruthenium exhibits proton-coupled electron transfer reaction and releases protons associated with the redox reaction. Its causes shift in equilibrium from difference. More information can be found Communication by T. Yamada et al. on page 4287.

The present status of neutron-proton scattering in the energy range from 20-70 MeV is reviewed. The data base covers total cross sections, differential cross sections and polarization observables. The efforts after 1980 did largely cnncentrate on precision measurements of the differential cross sections and accurate vector analyzing powers, using polarized neutron beams. Because of correlations...

The shell-model properties of proton halo states in proton-rich 1sOd shell nuclei are investigated. The most interesting cases appear to be those in 26327P and 27S. The parallel-momentum distributions of core fragments from proton stripping reactions may provide experimental insight into the structure of the halo states and the role played by the reaction mechanism. The “generalized Coulomb shi...

The Lamb shift measurement and theory are now both a dynamically developing field and we give a review of the current data. Critical comparison of theory and experiment can be done using a value of the proton charge radius and we pay attention to several results of its determination. The talk is devoted to the Lamb shift in the hydrogen atom. The workshop is for exotic atoms and first of all I ...

BACKGROUND AND PURPOSE Differentiation of normal pressure hydrocephalus (NPH) from other types of dementia and the selection of appropriate candidates for shunt surgery remain a clinical challenge. The aims of this study were to assess the efficacy of cerebral metabolites depicted by proton chemical shift imaging (1H-CSI) in distinguishing NPH from other dementias and to examine the relationshi...

The first proton transfer in the bacteriorhodopsin photocycle takes place during the L → M transition. Structural details of the pre proton transfer L intermediate have been investigated using experiments and computations. Here, we assess L-state structural models by performing hybrid quantum mechanical/molecular mechanical molecular dynamics and excitation energy calculations. The computations...
