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)
The rapid accumulation of whole-genome data has renewed interest in the study of using gene-order data for phylogenetic analyses and ancestral reconstruction. Current software and web servers typically do not support duplication and loss events along with rearrangements. MLGOMLGO (Maximum Likelihood for Gene-Order Analysis) is a web tool for the(More)
Paroxysmal kinesigenic dyskinesia is the most common type of paroxysmal movement disorder and is often misdiagnosed clinically as epilepsy. Using whole-exome sequencing followed by Sanger sequencing, we identified three truncating mutations within PRRT2 (NM_145239.2) in eight Han Chinese families with histories of paroxysmal kinesigenic dyskinesia:(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. Despite their simplicity, these approaches suffer from unstable(More)
—A 12 bit 2.9 GS/s current-steering DAC implemented in 65 nm CMOS is presented, with an 3 60 dBc beyond 1 GHz while driving a 50 load with an output swing of 2.5 ppd 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(More)
The rapid accumulation of whole-genome data has renewed interest in the study of genomic rearrangements. Comparative genomics, evolutionary biology, and cancer research all require models and algorithms to elucidate the mechanisms, history, and consequences of these rearrangements. However, even simple models lead to NP-hard problems, particularly in the(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)
BACKGROUND A medical intervention is a medical procedure or application intended to relieve or prevent illness or injury. Examples of medical interventions include vaccination and drug administration. After a medical intervention, adverse events (AEs) may occur which lie outside the intended consequences of the intervention. The representation and analysis(More)
In this paper, we describe the implementation of a software-based DSM model that supports variable-sized shard " regions " , where a region is a logical page that can be adjusted according to the access patterns of the user program. Our project supports the multiple reader, single writer (MRWS) replication algorithm, and uses a least-recently-used (LRU)(More)
