Cultivars of rice (Oryza sativa L.), especially the large-spikelet-type, often fail to achieve the high yield potential due to poor grain-filling of their inferior (late-flowering) spikelets. The superior (early-flowering) spikelets normally contain more abscisic acid (ABA) than the inferior spikelets. It was speculated that ABA might play a pivotal role in(More)
In many real-world OpenFlow-based SDN deployments, the ability to program heterogeneous forwarding elements built with different forwarding architectures is a desirable capability. In this paper, we discuss a data plane programming framework suitable for a flexible and protocol-oblivious data plane and show how OpenFlow can evolve to provide a generic(More)
Effective SDN control relies on the network data collecting capability as well as the quality and timeliness of the data. As open programmable data plane is becoming a reality, we further enhance it with the support of runtime interactive programming in order to cope with application dynamics, optimize data plane resource allocation , and reduce(More)
Alternate bearing (AB) trees, including Malus prunifolia, are characterized by alternating cycles of heavy (ON tree) and low (OFF tree) fruit loads. The mechanisms regulating the AB phenomenon have not been fully characterized. We completed an iTRAQ-based investigation of M. prunifolia to identify the proteome and metabolic differences between the leaves of(More)
The purpose of this study was to evaluate the capability and characteristics of different nanoleakage observation methods, including light microscope (LM), field-emission scanning electron microscope (FESEM), transmission electron microscope (TEM), and confocal laser scanning microscope (CLSM). Dentin specimens were bonded with either an etch-and-rinse(More)
Networking data analytics is increasingly used for enhanced network visibility and controllability. We draw the similarities between the Software Defined Networking (SDN) architecture and the MapReduce programming model. Inspired by the similarity, we suggest the necessary data plane innovations to make network data plane devices function as distributed(More)
The study takes a quantitative approach to test the determinants of commercial mortgage loan pricing at origination. The determinants include capital market risk, property market risks, mortgage terms and property characteristics. Taken into consideration of the endogenous factor between loan spread and LTV ratio, we use the OLS and 2SLS model to examine(More)
Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a well-known natural polyphenol compound. It is reported that resveratrol possesses strong anti-oxidative, anti-inflammatory, cardiovascular protective and cancer chemo-preventive effects. Therefore, there has been a considerable interest in its biological activity, pharmacological activity and also(More)
A simple, low-cost hydrothermal method was developed to synthesize 20-nm-diameter single-crystalline ytterbium silicate (Yb(2)Si(2)O(7) and Yb(2)SiO(5)) nanoparticles at 200 degrees C. This is nearly 1000 degrees C lower than that for the typical sol-gel route to ytterbium silicate powders. Obtained powders showed very low thermal conductivity, a suitable(More)
