The thermal properties of light vector and scalar mesons are investigated in the framework of QCD sum rules. The phenomenological side of the correlation function can be calculated using either the quark-hadron duality approach or in terms of two-pion continuum contributions. In the quark-hadron duality approach, a free parameter (hadronic threshold) arises in the phenomenological part and it i...

Research Summary The use of focused deterrence to reduce lethal violence driven by gangs and groups of chronic offenders has continued to expand since the initial Boston Ceasefire intervention in the 1990s, where prior evaluations have shown relatively consistent promise in terms of violence reduction. This study focuses on the capacity of focused deterrence to impact lethal violence in a chron...

introduction: the image quality as well as film speed is influenced by the film processing conditions. different combinations of films and processing methods affect the diagnostic accu-racy. temperature and developer exhaustion result in different image quality. the purpose of this study was to evaluate the influence of film type and processing conditions on caries detec-tion.  material and met...

Sentence-initial temporal clauses headed by before, as in "Before the scientist submitted the paper, the journal changed its policy", have been shown to elicit sustained negative-going brain potentials compared to maximally similar clauses headed by after, as in "After the scientist submitted the paper, the journal changed its policy". Such effects may be due to either one of two potential caus...

Visualization of cell migration during chemotaxis using spectral domain optical coherence tomography (OCT) requires non-standard processing techniques. Stripe artefacts and camera noise floor present in OCT data prevent detailed computer-assisted reconstruction and quantification of cell locomotion. Furthermore, imaging artefacts lead to unreliable results in automated texture based cell analys...
