Rice blast caused by Magnaporthe oryzae is one of the most destructive diseases of rice worldwide. The fungal pathogen is notorious for its ability to overcome host resistance. To better understand its genetic variation in nature, we sequenced the genomes of two field isolates, Y34 and P131. In comparison with the previously sequenced laboratory strain(More)
One of the most appealing features of constraint programming is its rich constraint language for expressing combinatorial optimization problems. This paper demonstrates that traditional combina-tors from constraint programming have natural counterparts for local search, although their underlying computational model is radically different. In particular, the(More)
BACKGROUND Breast cancer presents specific challenges both physiologically and psychologically to women, and consequently affect the patients' mental health. Psychosocial factors may play important roles in the symptoms and development of mental disorders among breast-cancer survivors. This study assesses the depression and anxiety status of breast-cancer(More)
Fetal bovine serum (FBS) shows obvious deficiencies in cell culture, such as low batch to batch consistency, adventitious biological contaminant risk, and high cost, which severely limit the development of the cell culture industry. Sericin protein derived from the silkworm cocoon has become increasingly popular due to its diverse and beneficial cell(More)
We sequenced Vibrio owensii strain SH-14, which causes serious acute hepatopancreatic necrosis disease (AHPND) in shrimp. Sequence analysis showed a large extrachromosomal plasmid, which encoded pir toxin genes and shared highly sequence similarity with the one observed in AHPND-causing Vibrio parahaemolyticus strains. The results suggest that this plasmid(More)
This paper proposes a 256 × 256 time-of-flight (TOF) image sensor based on the center-tap (CT) demodulation pixel structure. The image sensor can capture both the two-dimensional (2D) high speed image and the three-dimensional (3D) depth image. The CT pixel consists of two split pinned photodiode (PPD) regions and two pairs of transfer transistors. The(More)
The enzymatic condition for producing the anti-obesity hydrolysates from fish water-soluble protein was optimized with the aid of response surface methodology, which also derived a statistical model for experimental validation. Compared with neutral protease, papain and protamex, the porcine pancreas lipase inhibitory rate of hydrolysates from fish(More)
