Natural variation for primary root growth response to high Ca stress in Arabidopsis thaliana was studied by screening a series of accessions (ecotypes) under high Calcium (40 mM CaCl2) conditions. The genetic basis of this variation was further investigated by QTL analysis using recombinant inbred lines from Landsberg erecta (Ler) × Cape Verde Islands (Cvi) cross. Four QTLs were identified in c...

We present a full-3D statistical analysis of line edge roughness (LER) in sub0.1 μm MOSFETs. The modelling approach for line edges and the parameters used in the analysis take into account the statistical nature of the roughness. The results indicate that intrinsic fluctuations in MOSFETs due to LER become comparable in size to random dopant effects and can seriously inhibit scaling below 50 nm.

During the PEP-II LER commissioning run in July 1998 the beam pro le in the tune up dump pro le monitor just before LER injection showed an anomalous parbolic shape. The sextupole component of the eld of bend magnets B2 and B4 in the beginning of the south injection tunnel (SIT) was thought to be the cause of this. An o -line model of the B2/B4 bend magnet eld was created using DIMAD. Results o...

The SNPWave marker system, based on SNPs between the reference accessions Colombia-0 and Landsberg erecta (Ler), was used to distinguish a set of 92 Arabidopsis accessions from various parts of the world. In addition, we used these markers to genotype three new recombinant inbred line populations for Arabidopsis, having Ler as a common parent that was crossed with the accessions Antwerp-1, Kash...

Wireless sensors operating in harsh environments have the potential to be error-prone. This paper presents a distributive model-based diagnosis algorithm that identifies nonlinear sensor faults. The diagnosis algorithm has advantages over existing fault diagnosis methods such as centralized model-based and distributive model-free methods. An algorithm is presented for detecting common non-linea...

The hazard ratio (HR) is the most common measure of treatment effect in clinical trials that use time-to-event outcomes such as survival. When survival curves cross over or separate only after a considerable time, the proportional hazards assumption of the Cox model is violated, and HR can be misleading. We present two measures of treatment effects for situations where the HR changes over time:...

Root system size (RSS) is a complex trait that is greatly influenced by environmental cues. Hence, both intrinsic developmental pathways and environmental-response pathways contribute to RSS. To assess the natural variation in both types of pathways, we examined the root systems of the closely related Arabidopsis ecotypes Landsberg erecta (Ler) and Columbia (Col) grown under mild osmotic stress...
