It is well known that quadrant dependent (QD) random variables are also quadrant dependent in expectation (QDE). Recent literature has offered examples rigorously establishing the fact that there are QDE random variables which are not QD. The examples are based on convex combinations of specially chosen QD copulas: one negatively QD and another positively QD. In this paper we establish general ...

Improvements in quantum dot light-emitting device (QD-LED) performance are achieved by the choice of organic charge transporting layers, by use of different colloidal QDs for the different parts of the visible spectrum, and by utilizing a recently demonstrated robust QD deposition method. Spectrally narrow electroluminescence of our QD-LEDs is tuned over the entire visible wavelength range from...

BACKGROUND Two basal insulin analogues, insulin glargine once daily and insulin detemir once or twice daily, are marketed in Canada. OBJECTIVE To estimate the long-term costs of insulin glargine once daily (QD) versus insulin detemir once or twice daily (QD or BID) for type 1 (T1DM) and type 2 (T2DM) diabetes mellitus from a Canadian provincial government's perspective. METHODS A cost-minim...

Workload measurements in enterprise systems often lead to observe a dependence between the number of requests running at a resource and theirmean service requirements. However, multiclass performance models that feature these dependences are challenging to analyze, a fact that discourages practitioners fromcharacterizingworkloaddependences. We here focus on closed multiclass queueing networks a...

BACKGROUND Mesenchymal stem cells (MSCs) are multipotent cells with the potential to differentiate into bone, cartilage, fat and muscle cells and are being investigated for their utility in cell-based transplantation therapy. Yet, adequate methods to track transplanted MSCs in vivo are limited, precluding functional studies. Quantum Dots (QDs) offer an alternative to organic dyes and fluorescen...

The synthesis, structural characterization, optical spectroscopy, and electronic characterization of close packed solids prepared from CdSe QD samples tunable in size from 17 to 150 A in diameter (a<4.5%) are presented. We control the deposition of 3D QD glasses and superlattices by tailoring the solvent composition used to deposit the QD solids. We use high resolution scanning and transmission...

BACKGROUND AND AIMS According to existing literature, musicians are at risk of experiencing a range of painful musculoskeletal conditions. Recently, a novel digital technology was developed to investigate pain location and pain extent. The aim of this study was to describe pain location and pain extent in musicians using a digital method for pain drawing (PD) analysis. Additionally, the associa...

AIMS To characterize atomoxetine pharmacokinetics, explore the effect of the homozygous CYP2D6*10 genotype on atomoxetine pharmacokinetics and evaluate the tolerability of atomoxetine, in healthy Chinese subjects. METHODS Twenty-four subjects, all CYP2D6 extensive metabolizers (EM), were randomized to receive atomoxetine (40 mg qd for 3 days, then 80 mg qd for 7 days) or matching placebo (2 :...

Quantum dots (QD) have unique electronic and optical properties promoting biotechnological advances. However, our understanding of the toxicological structure-activity relationships remains limited. This study aimed to determine the biological impact of varying nanomaterial surface chemistry by assessing the interaction of QD with either a negative (carboxyl), neutral (hexadecylamine; HDA) or p...

III-Nitrides QD lasers are studied in detail. Two types of QD structures are considered, GaN/AlxGa1-xN/AlN and InxGa1-xN/ In0.04Ga0.96N /GaN. Effects of: QD size; QD and WL composition; and doping are studied through the calculations of gain, threshold current, and intensity modulation bandwidth. It is shown that GaN QDs are less sensitive to size fluctuations. Bandwidth increases with doping a...
