We report quantum transport measurements on two dimensional (2D) Si:P and Ge:P δ-layers and compare the inelastic scattering rates relevant for weak localization (WL) and universal conductance fluctuations (UCF) for devices of various doping densities (0.3-2.5 × 1018 m-2) at low temperatures (0.3-4.2 K). The phase breaking rate extracted experimentally from measurements of WL correction to cond...

This paper describes how one can reduce the memory access time with pre-emphasis (PE) pulses even in non-volatile random-access memory. Optimum PE pulse widths and resultant minimum word-line (WL) delay times are investigated as a function of column address. The impact process variation constant WL, cell current, resistance deciding path on optimum discussed. WL modeled fitting curves address a...

Extended waterlogging (WL) conditions in heavily manured soils can change soil phosphorus (P) dynamics. We assessed the effects of moisture regimes (field capacity (FC) and WL) P rates on (i) dry matter (DM) yield offtake ryegrass, (ii) changes Fe3+, Fe2+, P, (iii) risk leaching. The treatments were tested a four-month greenhouse experiment using intact columns annual ryegrass (Lolium multiflor...

We present long-slit 7.5–13.5 mm spectra of WL 16, a Herbig Ae star in the r Ophiuchi dark cloud that is surrounded by a ∼1000 AU diameter infrared-emitting nebula. Mid-IR emission features are detected in every region of the nebula from center to edge, and the underlying continuum color temperature is approximately 10 times hotter than would be expected from large grains in thermal equilibrium...

BACKGROUND 'Dry eye' appears to be the main contributor to the symptoms of computer vision syndrome. Regular breaks and the use of artificial tears or certain eye drops are some of the options to reduce visual discomfort. A combination of yoga practices have been shown to reduce visual strain in persons with progressive myopia. The present randomized controlled trial was planned to evaluate the...

INTRODUCTION The aim of this study was to evaluate the effect of needle-insertion depth on the irrigant flow inside a prepared root canal during final irrigation with a syringe and two different needle types using a Computational Fluid Dynamics (CFD) model. METHODS A validated CFD model was used to simulate irrigant flow from either a side-vented or an open-ended flat 30-G needle positioned i...

Postoperative intra-abdominal or intrathoracic adhesions sometimes cause significant morbidity. We have designed three types of alginate-based treatments using strongly cross-linked (SL), weakly cross-linked (WL), and non-cross-linked (NL) alginate with calcium gluconate. In rat experiments, we compared the antiadhesive effects of the three types of alginate-based treatments, fibrin glue treatm...

The purpose of this study was to evaluate the movement of gutta-percha into lateral grooves and depressions in the apical 7 mm of a root canal by using the System B Heat Source for the continuous wave of condensation and the Obtura II for the backfill. A split-tooth model was constructed with lateral grooves and dentin depressions prepared at 1, 3, 5, and 7 mm from working length (WL). The stud...

AIM To determine the impact of Charlson comorbidity index (CCI) on waiting list (WL) and post liver retransplantation (LRT) survival. METHODS Comparative study of all adult patients assessed for primary liver transplant (PLT) (n = 1090) and patients assessed for LRT (n = 150), 2000-2007 at our centre. Demographic, clinical and laboratory variables were recorded. RESULTS Median age for all p...

Widely Linear (WL) Minimum Mean Square Error (MMSE) estimation has received a great interest these last 20 years for second order (SO) noncircular signals. In the context of radio communications networks, it has been shown in particular that WL MMSE receivers allow to implement Single Antenna Interference Cancellation (SAIC) of one rectilinear interference, such as Binary Phase Shift Keying (BP...
