We describe a general method for calculating the infra-red limit of physical quantities in unitary quantum field theories. Using analyticity of Green functions in a complex scale parameter, the infra-red limit is expressed as a contour integral entirely in the ultra-violet region. The infra-red limit is shown to be the limit of the Borel transform of the physical quantity. The method is illustr...

The case is presented of an 8 1-year-old female coming to our observation after two non radical local excisions of a Merkel cell carcinoma of the sub-mental skin region. After a wide local excision, with en bloc elective bilateral neck dissection, simultaneous reconstruction with an infra-hyoid myocutaneous flap was performed. A brief overview concerning this rare tumour is presented and the su...

This paper presents the results of several large-scale studies of face recognition employing visible light and infra-red (IR) imagery in the context of principal component analysis. We find that in a scenario involving time lapse between gallery and probe, and relatively controlled lighting, (1) PCA-based recognition using visible light images outperforms PCA-based recognition using infra-red i...

In non-pulsatile cardiopulmonary bypass surgery, middle cerebral artery blood flow velocity (BFV) is characterized by infra-slow oscillations of approximately 0.06Hz, which are paralleled by changes in total EEG power variability (EEG-PV), measured in 2s intervals. Since the origin of these BFV oscillations is not known, we explored their possible causative relationships with oscillations in EE...
