MOTIVATION In order to facilitate a systematic study of the promoters and transcriptionally regulatory cis-elements of the yeast Saccharomyces cerevisiae on a genomic scale, we have developed a comprehensive yeast-specific promoter database, SCPD. RESULTS Currently SCPD contains 580 experimentally mapped transcription factor (TF) binding sites and 425(More)
AIMS/HYPOTHESIS FTO harbours the strongest known obesity-susceptibility locus in Europeans. While there is growing evidence for a role for FTO in obesity risk in Asians, its association with type 2 diabetes, independently of BMI, remains inconsistent. To test whether there is an association of the FTO locus with obesity and type 2 diabetes, we conducted a(More)
Phytohormones are indispensable factors regulating plant cell dedifferentiation. In this paper, different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D) and kinetin (KIN) were incorporated in the culture medium and the anatomy of dedifferentiated cells prior to callus formation from Arabidopsis thaliana petiole explants was examined. The results(More)
Concerns about potential health hazard of nanomaterials are growing. To determine the potential toxicity of metal oxide nanoparticles, human SH-SY5Y neuroblastoma and H4 neuroglioma cells were exposed to Fe 2 O 3 , CuO, and ZnO nanoparticles and their metal ion counterparts (Fe 3+ , Cu 2+ , and Zn 2+) at a concentration range of 0.01-100 µM for 48 hours,(More)
In this paper we develop a new superfast solver for Toeplitz systems of linear equations. To solve Toeplitz systems many people use displacement equation methods. With displacement structures, Toeplitz matrices can be transformed into Cauchy-like matrices using the FFT or other trigonometric transformations. These Cauchy-like matrices have a special(More)
The distance to uncontrollability for a linear control system is the distance (in the 2-norm) to the nearest uncontrollable system. We present an algorithm based on methods of Gu and Burke–Lewis–Overton that estimates the distance to uncontrollability to any prescribed accuracy. The new method requires O(n 4) operations on average, which is an improvement(More)
The register transfer abstraction (RTL) has been established as the industrial standard for ASIC design, soft IP exchange and the backend interface for chip design at higher level. Unfortunately, the " synthesizable " VHDL/Verilog in-carnation of the RTL abstraction has problems which prevent it from more productive use. For example, the confusion as the(More)
In this paper, we propose a novel method to differentiate packet loss based on interference energy and timing relative to desired signal for a CSMA-based dense wireless network. All measurements are conducted locally at transmitters, and therefore require no additional over-the-air overhead. Our method also separately estimates the PER (packet error rate)(More)
