Evidence for the decay
(Elsevier, 1987-04-30)
The inclusive production of [eta] mesons in tau lepton decay has been studied using the High Resolution Spectrometer at the PEP e+e- facility. The data sample corresponds to an integrated luminosity of 300 pb-1 and the ...
Polarization of [Sigma]0 hyperons in inclusive production from 28.5 GeV/c protons on beryllium
(Elsevier, 1987-07-09)
The polarization of [Sigma]0 hyperons produced in an inclusive reactons hasbeen measured for the first time. From a sample of 11 000 events produced by 28.5 GeV/c ptorons in the reaction p+Be-->[Sigma]0+X, the [Sigma]0 ...
Characterization of the flavin–protein interaction in L ‐Lactate oxidase and old yellow enzyme by resonance inverse Raman spectroscopy
(John Wiley & Sons, Ltd., 1987-06)
Resonance inverse Raman spectroscopy was used to examine the interactions between the flavin and surounding protein in L ‐lactate oxidase (from Mycobacterium smegmatis ) and Old Yellow Enzyme (from brewer's bottom yeast). ...
CT evaluation of mediastinal masses
(Elsevier, 1987)
CT is an important modality for imaging mediastinal masses, and certain CT attenuation features (fat, calcium, or water attenuation, contrast enhancement) are well known to suggest specific diagnoses. In a series of 132 ...
Measurement of the lifetime of hadrons containing the b-quark
(Elsevier, 1987-09-03)
Data collected with the High Resolution Spectrometer at PEP, corresponding to an integrated luminosity of 200 pb-1 of e+e- annihilation at 29 GeV, were used to measure the mean lifetime of hadrons containing the bottom ...
Natural convection in evaporating sessile drops with crystal growth
(Elsevier, 1987)
Laser shadowgraphy is employed to study interfacial instability and natural convection inside a minute drop evaporating on a plate with internal crystal growth. Both pure and binary liquids are considered. Two methods of ...
Prediction of spark kernel development in constant volume combustion
(Elsevier, 1987-09)
Combustion initiation is studied in atmospheric pressure propane-air mixtures in a constant volume bomb with a high speed (10,000 fps) laser schlieren system. The spark current and voltage waveforms are simultaneously ...
Could the quark electroweak and mass eigenstates coincide?
(Elsevier, 1987-10-15)
We conjecture that in the absence of new mixing effects at the weak scale the standard quark mass eigenstates and the quark weak eigenstates would coincide, and that for all three families a simple hierarchy would apply, ...
Applications of [131I]m-iodobenzylguanidine ([131I]MIBG)
(Elsevier, 1987)
The development of the aralkylguanidine [131I]m-iodobenzylguanidine ([131I]MIBG) in the University of Michigan Nuclear Medicine Division has led to diagnostic and therapeutic evaluations of all the neuroendocrine tumors. ...
Comparative study of the growth processes of GaAs, AlGaAs, InGaAs, and InAlAs lattice matched and nonlattice matched semiconductors using high‐energy electron diffraction
(The American Institute of Physics, 1987-04-15)
We have examined the effect of growth temperature and growth interruption time on molecular‐beam‐epitaxial growth of GaAs, Al0.3Ga0.7As, and InxGa1−xAs on GaAs substrates and In0.53Ga0.47As and In0.52Al0.48As on InP ...
