Progress in computing inclusive B decay spectra. [PDF]
, 2010 We review the progress in the QCD calculation of inclusive decay spectra. It was recently shown that the inherent infrared finiteness of inclusive spectra extends beyond the level of logarithms.

Preliminary results for the extraction and measurement of cosmogenic in situ C-14 from quartz [PDF]
, 2004 Radiocarbon is produced within minerals at the earth's surface (in situ production) by a number of spallation reactions. Its relatively short half-life of 5730 yr provides us with a unique cosmogenic nuclide tool for the measurement of rapid erosion ...

Predicting ambient aerosol thermal-optical reflectance (TOR) measurements from infrared spectra: organic carbon [PDF]
Atmospheric Measurement Techniques, 2015 Organic carbon (OC) can constitute 50% or more of the mass of atmospheric particulate matter. Typically, organic carbon is measured from a quartz fiber filter that has been exposed to a volume of ambient air and analyzed using thermal methods such as ...

The role of quartz during deformation of polyphase rocks [PDF]
, 2013 In this thesis, deformation mechanisms, rheology and the related microstructural evolution of quartz during deformation of polyphase rocks are investigated in natural, high temperature, small scale shear zones in granitoids. Selected shear zones are from

Investigations into the gas-phase photolysis and OH radical kinetics of nitrocatechols: implications of intramolecular interactions on their atmospheric behaviour [PDF]
Atmospheric Chemistry and Physics, 2022 The Environmental Simulation Chamber made of Quartz from the University “Alexandru Ioan Cuza” (ESC-Q-UAIC), at Iasi, Romania, was used to investigate the gas-phase reaction rate coefficients for four nitrocatechols toward OH radicals under simulated ...

Pseudo-two-girdles c-axis fabric patterns in a quartz-feldspar mylonite (Costabona granodiorite, Canigo massif) [PDF]
, 2012 An example of the relationship that exist between the preferred crystaliografic orientation of quartz grains and the attitude of the mylonite foliation of quartz-feldspar mylonites is described. These rocks are the result of the inhomogeneous deformation

Infrared Spectra and Vapor Pressures of Crystalline C2N2, with Comparisons to Crystalline HCN
The Planetary Science Journal, 2023 In a continuation of our work on nitriles, we have examined cyanogen (C _2 N _2 ) as a crystalline solid, comparing the results to our recent work on crystalline hydrogen cyanide (HCN).
