Laser-induced Chemical Vapour Deposition of silicon carbonitride coatings and powders has been investigated using hexamethyldisilazane (HMDS) and ammonia as reactants. An industrial CW CO2-laser in parallel configuration has been used to heat up the reactant gases. HMDS dissociates in the laser beam and reactive radicals are formed which increase rapidly in molecular weight by an addition mecha...

In aplastic anemia (AA), contraction of the stem cell pool may result in oligoclonality, while in myelodysplastic syndromes (MDS) a single hematopoietic clone often characterized by chromosomal aberrations expands and outcompetes normal stem cells. We analyzed patients with AA (N = 93) and hypocellular MDS (hMDS, N = 24) using single nucleotide polymorphism arrays (SNP-A) complementing routine ...

Banerjee, C. K., Girling, D. J., and Wigglesworth, J. S. (1972). Archives of Disease in Childhood, 47, 509. Pulmonary fibroplasia in newborn babies treated with oxygen and artificial ventilation. A retrospective clinicopathological study was carried out on newborn babies who had died over a 5-year period, had received oxygen therapy, and had lived for 48 hours or longer. 23 of 81 babies had pul...

While head-mounted display (HMD) technologies have undergone great developments since the first HMD for 3D visualization originated by Ivan Sutherland in the 1960’s, HMD technologies have suffered from tradeoffs in capability and limitation. The main issues of HMDs include the tradeoff between resolution and field of view (FOV), the presence of large distortion for wide field of view designs, t...

Using bis(amide) Zn(HMDS)2 (HMDS = 1,1,1,3,3,3-hexamethyldisilazide) as a precursor, this study explores the synthesis of N-heterocyclic carbene stabilized mixed amido-hydride zinc complexes using two alternative hydride sources, namely dimethylamine borane (DMAB) and phenylsilane PhSiH3. Hydride-rich zinc cluster Zn4(HMDS)2H6·2IPr () (IPr = 1,3-bis(2,6-di-isopropylphenyl)imidazol-2-ylidene), w...

Impending advances in the quality and affordability of Head-Mounted Displays (HMDs) such as the Oculus Rift and the Sony Morpheus indicate that the delivery of virtual training may be done increasingly effectively through such devices. As in many simulation applications including ICT projects, the user in the HMD is represented as an avatar present in the virtual environment, which can be seen ...

The incidence of difficulty in tracheal intubation has been reported to range from 0.5 to 18% in patients undergoing surgery. We aimed to elucidate the role of upper lip bite test (ULBT) with other prevailing tests, hyomental/thyrosternal distances (HMD/TSD), and the mandible length (ML) and their possible correlation in predicting difficulty in intubation. After institutional approval and info...

DNAmethylation is a fundamental epigeneticmodification in vertebrate genomes and a small fraction of genomic regions is hypomethylated. Previous studies have implicated hypomethylated regions in gene regulation, but their functions in vertebrate development remain elusive. To address this issue, we generated epigenomic profiles that include base-resolution DNA methylomes and histone modificatio...

Techniques to generate novel scenes have been proposed in computer vision research. In addition, there have been a lot of 3D models written in VRML for viewing on the WWW. However, the depth of 3D images cannot easily be sensed without special hardware such as HMDs and without special equipment, e.g., shutter and poralized glasses. In this paper, a method is proposed that uses motion parallax a...

Intelligent Tutoring Systems (ITSs) have been shown to be effective in training a variety of military tasks. However, these systems are often limited to laboratory settings on standard PCs and laptops which focus on exercising cognitive skills (e.g., decision-making and problem solving) and may potentially limit the learning and retention of the dismounted Soldiers and Marines training to maste...
