Enhancing the learning of evolutionary anthropology skills by combining student-active teaching with actual and virtual immersion of Master's students in fieldwork, laboratory practice, and dissemination.

Higher education in evolutionary anthropology involves providing students with in-depth knowledge of biological and cultural heritage sites and collections that are frequently inaccessible. Indeed, most sites, fossils, and archaeological remains can be visited or manipulated only rarely and solely by specialists with extensive experience. Owing to the development of 3D and medical imaging techniques, this fragile heritage is now more widely accessible, and in a dynamic way.

THz wave propagation in two-dimensional metallic photonic crystal with mechanically tunable photonic-bands.

Transmission and dispersion relation of THz waves in two-dimensional photonic crystal (PC) composed of metal rods are studied by using finite-difference time-domain simulation and THz time-domain spectroscopy measurement. The PC is embedded in a parallel metal plate waveguide with an air gap between the PC and one of the plates. The photonic-band-gap well-defined at small air gap narrows systematically with opening the air gap and disappears when the air gap is 2 ~ 3 times the rod height, where the two-dimensional nature of PC is destroyed.

Mechanical active control of surface plasmon properties.

We present a multilayer device which allows the control of Surface Plasmon (SP) propagation properties (propagation length and extension). A simple modification on an inner air gap thickness strongly affects SP propagation mode due to coupling with Parallel-Plate (PP) mode.

[Prognosis of the thyroid carcinomas after surgery (author's transl)].

The authors review 140 cases and show the prime importance of the patient's age and the histological type in the prognosis of the operations of thyroid carcinoma (with the exception of solitary malignant cold nodule). The survival rate is higher with the papillary carcinoma of young patients, even though an extensive development of lymph nodes occurs, whereas metastases are encountered in the evolution of follicular carcinoma with increased risks. The anaplastic carcinoma which occurs mainly in aged people, is the worst of all.
