Fractal analyses reveal independent complexity and predictability of gait
2017
Locomotion is a natural task that has been assessed since decades and used as a proxy to highlight impairments of various origins. Most studies adopted classical linear analyses of spatio-temporal gait parameters. Here, we use more advanced, yet not less practical, non-linear techniques to analyse gait time series of healthy subjects. We aimed at finding more sensitive indexes related to spatio-temporal gait parameters than those previously used, with the hope to better identify abnormal locomotion. We analysed large-scale stride interval time series and mean step width in 34 participants while altering walking direction (forward vs. backward walking) and with or without galvanic vestibular…
On the phylogeny and zoogeography of the leptarctines (Carnivora, Mammalia)
1982
A restudy of the skull and mandible ofLeptarctus neimenguensis Zhai from the Middle Miocene of China and the preparation of its auditory region led to the recognition of new features. The most important among them is the presence of a small suprameatal fossa partly hidden in the bony mastoid process corresponding to the structure described inPlesiogale andParagale (Schmidt-Kittler 1981) and representing the most primitive type of the mustelid middle ear.
Conservative parotidectomy in infancy and childhood
1975
Summary The indication for operations of benign tumours of the salivary glands in infancy and childhood is taken with great caution and is only partially recommended as the therapy of choice. This applies especially to hemangiomas, since spontaneous retrogression has been observed and there is the danger of damage to the facial nerve during surgery. Knowing unsatisfactory late cases of hemangiomas the author recommends conservative parotidectomy in cases of fast-growing hemangiomas. The anatomic structures in infancy, as well as the lack of pneumatisation of the mastoid process and the fragility of the cartilagineous auditory meatus should be taken into consideration during surgical explora…
