Vacuum Polarization in QED with World-Line Methods [PDF]
, 2000 Motivated by several recent papers on string-inspired calculations in QED, we here present our own use of world-line techniques in order to calculate the vacuum polarization and effective action in scalar and spinor QED with external arbitrary constant ...

Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)
The Anatomical Record, EarlyView.Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

Severity of Spinal Cord Injury Influences Diffusion Tensor Imaging of the Brain [PDF]
, 2016 Background: The purpose of this study was to determine whether DTI changes in the brain induced by a thoracic spinal cord injury are sensitive to varying severity of spinal contusion in rats. Methods: A control, mild, moderate, or severe contusion injury

Anatomical Sciences Education, EarlyView.Abstract Teaching white matter (WM) anatomy to undergraduates is challenging. This is partly because WM fibers are oriented intricately and Klingler's dissection, the gold standard method used to demonstrate it, often requires time, advanced anatomical knowledge, and refined dissection skills.

Empirical comparison of diffusion kurtosis imaging and diffusion basis spectrum imaging using the same acquisition in healthy young adults [PDF]
, 2017 As diffusion tensor imaging gains widespread use, many researchers have been motivated to go beyond the tensor model and fit more complex diffusion models, to gain a more complete description of white matter microstructure and associated pathology.
