We demonstrate an enhanced photo-sensitivity (PS) through an increased light-trapping using surface nano-structuring technique by inductively coupled plasma (ICP) etching on multi-walled carbon nanotube (MWCNT) etch masked Si with hexamethyl-disilazane (HMDS) dispersion. In order for a systematic comparison, four samples are prepared, respectively, by conventional photolithography and ICP etchi...

First demonstrated in 1968 [Suther68], head-mounted displays [HMDs] have the potential to immerse a user inside a “virtual world,” where the user can view and interact with computer-generated three-dimensional environments. However, today’s systems far fall short of creating completely convincing virtual environments. Much work remains in overcoming limitations in the technologies that drive HM...

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 ...

With the recent introduction of low cost head mounted displays (HMDs), prices of HMD-based virtual reality setups dropped considerably. In various application areas personal head mounted displays can be utilized for groups of users to deliver different context sensitive information to individual users. We present a hardware setup that allows attaching 12 or more HMDs to a single PC. Finally we ...

INTRODUCTION Little research exists regarding hospice medical directors (HMD). This project describes the HMD's background and training, clinical roles, and current function within the hospice organization and their interdisciplinary groups. METHODS A survey was mailed to each licensed hospice that was also a member of the state hospice association in one state. Thirty-one HMDs from 31 hospic...

A highly efficient CH3CN-promoted hexamethyldisilazane per-O-trimethylsilylation of amino sugars was developed. Its applications in homogenous N-functionalisation and a concise synthesis of glucosamine 6-phosphate are described.

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 cyto...

OBJECTIVE We provide a review and analysis of much of the published literature on visual perception issues that impact the design and use of head-mounted displays (HMDs). BACKGROUND Unlike the previous literature on HMDs, this review draws heavily from the basic vision literature in order to help provide insight for future design solutions for HMDs. METHOD Included in this review are articl...

Six alkali metal tris(HMDS) magnesiate complexes (HMDS, 1,1,1,3,3,3,-hexamethyldisilazide) containing chiral diamine ligands have been prepared and characterised in both the solid- and solution-state. Four of the complexes have a solvent-separated ion pair composition of the form [{M·(chiral diamine)(2)}(+){Mg(HMDS)(3)}(-)] [M = Li for 1 and 3, Na for 2 and 4; chiral diamine = (-)-sparteine for...

Hypocellular or hypoplastic myelodysplastic syndromes (HMDS) are a distinct subgroup accounting for 10-15% of all MDS patients, that are characterized by the presence of bone marrow (BM) hypocellularity, various degree of dysmyelopoiesis and sometimes abnormal karyotype. Laboratory and clinical evidence suggest that HMDS share several immune-mediated pathogenic mechanisms with acquired idiopath...
