Light Absorbing Diamond for Solar Energy Conversion
High-temperature solar cells are possible by exploiting the Photon-Enhanced Thermionic Emission (PETE) concept, which represents a novel and very attractive mechanism for the exploitation of solar radiation, e...

Anatomy of the Subaxial Cervical Spine
The cervical spine is a deep anatomical structure centrally located in the axial view of the neck and surrounded by a thick and powerful muscular compartment. It is surrounded and contained by the deep layer o...

Exemplificative Cases in Cervical Spine
Fourteen-year-old female, progressive neck pain in the nuchal area radiating to the head with painful contracture of the right paraspinal musculature. Pain was unrelated to weight-bearing and was increasing du...

Cervical Spine Instrumentation
Anterior cervical discectomy and fusion (ACDF) is often used as a surgical treatment for cervical degenerative disorders. Numerous long-term follow-up studies have shown that is effective in case of cervical m...

Surgical Planning in Cervical Spine Oncologic Patients
Primary bone tumors of the spine are very rare [1]; they comprise only 10 % or less of all bone tumors. In the United States, about 7,500 new cases are estimated per year. The overall world occurrence can be e...

Posterior Approach to Cervical Spine
In the neck, the spine takes up the mid-part of the cross-sectional area, and its posterior aspect is surrounded by a thick layer of powerful muscles (see §2. Anatomy).

Anesthesiological Management and Patient Positioning
Prior to the surgery, reproduction of symptoms with extension of the neck should be assessed. Extension may help for better exposure and visualization. However, the severity of stenosis may limit the amount of...

UV Laser Beam Profilers Based on CVD Diamond
1D and 2D detector arrays have been realized on 270 μm thick 10 × 10 mm2 CVD diamond samples. The relatively high resistivity of diamond specimens in the dark (>3 × 1012 Ωcm) allowed the fabrication of photocondu...

UV Schottky Sensors Based on Wide Bandgap Semiconductors
Planar Al/GaN/Ni Schottky diodes were realized on GaN films deposited on sapphire substrates and characterized in the dark and under illumination. The optoelectronic characteristics of GaN photodetectors appea...

Photoconductive Position Sensitive CVD Diamond Detectors
Different contact structures were studied to realize CVD-diamond sensors able to detect light beam displacements. Photons irradiate the sample backside where a mesh contact is used for device biasing. Photogen...

Principal Components Identify MLP Hidden Layer Size for Optimal Generalisation Performance
One of the major concerns when implementing a supervised artificial neural network solution to a classification or prediction problem, is the network’s performance on unseen data. The phenomenon of the network...

Fahlman-Type Activation Functions Applied to Nonlinear PCA Networks Provide a Generalised Independent Component Analysis
It has been shown experimentally that Oja’s nonlinear principal component analysis (PCA) algorithm is capable of performing an independent component analysis (ICA) on a specific data set [7]. However, the dyna...
