- 《Journal of Mass Spectrometry》 被引量: 39发表: 2003年 Silicon clusters doped with an yttrium metal atom impurity The structures, energetics, and bonding properties of small Sin (n = 1–6) clusters doped with an yttrium atom are studied by means of a hybrid density fun... C Xiao,J...
Photoproduction of large-mass lepton pairs at HERA as a probe of the small $x$ structure of the protondoi:10.1016/0370-2693(93)90020-IThe photoproduction of Drell-Yan lepton pairs at HERA is studied. We show that in the backward rapidity region the cross section is strongly sensitive to ...
Proton transfer, either from a protonated molecule to a neutral molecule or from a neutral molecule to a negative ion, often proceeds at, or near, the collision rate when exothermic (seeFigure 1). When the proton-transfer exothermicity is large, internal energy can appear in the protonated pr...
In this picture of quark–antiquark creation by the strong force, the probability distributions as a function of momentum for the presence of up and down antimatter quarks should be nearly identical, given that their masses are very similar and small compared to the mass of the proton3. Here...
However, alkali metal ions typically show a limited diffusion rate in molecular materials due to its relatively large ionic radii. Compared with lithium ions, proton could become one of the effective ions to control magnetism, due to its small size and high ionic conductivity originating from the...
Charged D* meson production was studied in proton-proton collisions at a center of mass energy of 200 GeV using the Solenoidal Tracker at RHIC (STAR) at Br... S Hansen - 《Environmental Monitoring & Assessment》 被引量: 7发表: 2005年 Exclusive production of $\\ensuremath{\\omega}$ meson...
Tightly bound water is considered to interact strongly with sulfonic acid groups and thus does not freeze, while loosely bound water interacts weakly with the polymer chain yielding relatively small values of ΔHf, and free water behaves similarly to bulk water yielding relatively large values of Δ...
Ten non-small cell lung cancer (NSCLC) patients with wide ranges of tumor sizes, locations and motion magnitudes were used to evaluate the potential of our 4DRO method.Table 1shows the magnitude of respiratory motion of the center of mass of the GTV, the size of the ITV, the tumor locati...
