Photomultipliers are commonly used in commercial PET scanner as devices which convert light produced in scintillator by gamma quanta from positron-electron annihilation into electrical signal. For proper analysis of obtained electrical signal, a photomultiplier gain curve must be known, since gain can be significantly different even between photomultipliers of the same model. In this article we...

The 364 nm photoelectron spectra of AuOand AuShave been measured. The electron affinities of AuO and AuS have been determined to be 2.374 ( 0.007 and 2.469 ( 0.006 eV, respectively. The electronic ground states of the neutral diatomics are Πi states, and the spin-orbit splitting between the XΠ1/2 and Π3/2 states is 1440 ( 80 cm-1 for AuO and 1280 ( 60 cm-1 for AuS. A 590 ( 70 cm-1 vibrational p...

This study intends to investigate the patterns of intergenerational mobility among Korean men and to assess the extent to which the Korean case shows distinctiveness within the framework of the core model proposed by Erikson and Goldthorpe (1992a). The greater dissimilarity between origins and destinations associated with massive movement of labor forces out of farm origins, and in the process ...

We propose a method for the computer simulation of Auger electron and photoelectron diffraction patterns by evaluating the amplitude of propagation paths from the detector to the electron-emitting source, justified by Helmholtz’s reciprocity principle. The method offers significant computational advantages over previous schemes, and suggests an easy extension to enable the calculation of a stru...

There is a long-standing debate in criminology about the relative impact of static versus dynamic factors on criminal behavior. Researchers interested in estimating the impact of dynamic factors like prior offending or association with delinquent peers on criminal offending must control for static factors like intelligence, family background, or self-control, which could plausibly be correlated...

As novel applications using terahertz radiation are developed, there is an increased demand for sensitive terahertz detectors. This has led to new approaches for enhancing the response of terahertz detectors. Results were recently reported on the terahertz response of a p-type AlGaAs/GaAs, n-type GaAs/AlGaAs, n-type GaN/AlGaN, and p-type GaSb/GaSb Interfacial Workfunction Internal Photoemission...

Using angle-resolved photoemission, we have mapped the spin density wave phase diagram of Cr(110) thin films grown on W(110) as a function of film thickness, temperature, and hydrogen surface coverage. We find commensurate and incommensurate phases that are separated by nearly continuous transitions. Surface localized electron states play a key role in the observed thin film phase behaviors. Ou...

Browsing is a part of book seeking that is important to readers, poorly understood, and ill supported in digital libraries. In earlier work, we attempted to understand the impact of browsing on book borrowing by examining whether books near other loaned books were more likely to be loaned themselves, a phenomenon we termed the neighbour effect. In this paper we further examine the neighbour eff...
