Upland cotton is a model for polyploid crop domestication and transgenic improvement. Here we sequenced the allotetraploid Gossypium hirsutum L. acc. TM-1 genome by integrating whole-genome shotgun reads, bacterial artificial chromosome (BAC)-end sequences and genotype-by-sequencing genetic maps. We assembled and annotated 32,032 A-subgenome genes and(More)
A 12 bit 2.9 GS/s current-steering DAC implemented in 65 nm CMOS is presented, with an dBc beyond 1 GHz while driving a 50 load with an output swing of 2.5 and dissipating a power of 188 mW. The SFDR measured at 2.9 GS/s is better than 60 dB beyond 340 MHz while the SFDR measured at 1.6 GS/s is better than 60 dB beyond 440 MHz. The increase in performance(More)
Running compute-intensive or blocking I/O operations in the UI event thread of smartphone apps can severely degrade responsiveness. Despite the fact that Android supports writing concurrent code via AsyncTask, we know little about how developers use AsyncTask to improve responsiveness. To understand how AsyncTask is used/underused/misused in practice, we(More)
Active queue management (AQM) is an effective method to enhance congestion control, and to achieve tradeoff between link utilization and delay. The de facto standard, random early detection (RED), and most of its variants use queue length as a congestion indicator to trigger packet dropping. The proportional-integral (PI), use both queue length and traffic(More)
This paper presents a multi-band multi-mode class-AB power amplifier, which utilizes continuously tunable input and output matching networks integrated in a low-loss silicon-on-glass technology. The tunable matching networks make use of very high Q varactor diodes (Q>100 @ 2 GHz) in a low distortion anti-series configuration to achieve the desired source(More)
Over the last years several low-power time-interleaved (TI) ADC designs in the 2.5-to-3.0GS/s range have been published [1-3], intended for integration in applications like radar, software-defined radio, full-spectrum cable modems, and multi-channel satellite reception. It is to be expected that future generations of these applications will require a higher(More)
Adaptive Random Testing (ART) is a testing technique which is based on an observation that a test input usually has the same potential as its neighbors in detection of a specific program defect. ART helps to improve the efficiency of random testing in that test inputs are selected evenly across the input spaces. However, the application of ART to(More)
Computing the edit distance between two genomes is a basic problem in the study of genome evolution. The double-cut-and-join (DCJ) model has formed the basis for most algorithmic research on rearrangements over the last few years. The edit distance under the DCJ model can be computed in linear time for genomes without duplicate genes, while the problem(More)
