In this paper, three numerical models of typhoon surge are discussed briefly. The first one is called Five-basin Model (FbM). The second one is called SLOSH (Sea, Lake and Overland Surges from Hurricanes), 5 SLOSH-type basins covering the entire China coastlines were developed in a joint project between authors and Jelesnianski et al. (1992) of U.S.A. The two models have been used in real-time forecasting of typhoon surge. The third one is a new developing model in which inundation using the scheme originated by Flather and Heaps (1975) and astronomical used was included. A multiple nested grid system was developed.

Safe Anesthesia

Anesthesiology is an evolving branch. Most of the procedures done by anesthesiologists, are blind except for endotracheal intubation. Ultrasonography (USG) helps anesthesiologists to see the actual anatomy in real time and thus helps them to give safe anesthesia minimizing the complications in every aspect of the field like difficult airway, vascular access, regional anesthesia, chronic pain management and critical care.

The brown planthopper (BPH), Nilaparvata lugens, is a serious pest of rice throughout Asia. Yeast-like symbionts (YLS) are endosymbionts closely linked with the development of BPH and the adapted mechanism of BPH virulence to resistant plants. In this study, we used semi-quantitative DGGE and absolute quantitative real-time PCR (qPCR) to quantify the number of the three YLS strains (Ascomycetes symbionts, Pichia-like symbionts, and Candida-like symbionts) that typically infect BPH in the nymphal stages and in newly emerged female adults. The quantities of each of the three YLS assessed increased in tandem with the developing nymphal instar stages, peaking at the fourth instar stage, and then declined significantly at the fifth instar stage. However, the amount of YLS present recovered sharply within the emerging adult females. Additionally, we estimated the quantities of YLS for up to eight generations after their inoculation onto resistant cultivars (Mudgo, ASD7, and RH) to reassociate the dynamics of YLS with the fitness of BPH. The minimum number of each YLS was detected in the second generation and gradually increased from the third generation with regard to resistant rice varieties. In addition, the Ascomycetes symbionts of YLS were found to be the most abundant of the three YLS strains tested for all of the development stages of BPH.

Abstract During the second half of the seventeenth century, there were at least three embassies between the Spaniards of Manila and the Fujian based Zheng regime. The first embassy took place in 1656 ordered by the Spanish governor in Manila. The ambassadors were two captains of the city, and its aim was to re-establish trade relations, which had been severed many months before. In response, Zheng Chenggong sent his cousin to the Philippine islands to settle several business arrangements regarding Fujianese trade. In 1662, Zheng Chenggong took the initiative of sending the Dominican Victorio Riccio, who worked as missionary in the Catholic mission at Xiamen, as emissary to the Governor of the Philippines, don Sabiniano Manrique de Lara. The third embassy took place in 1663. Thereupon, Zheng Jing, Zheng Chenggong’s successor, sent Riccio to Manila for signing a peace pact and for re-establishing trade. The three embassies were related to the Zheng’s purpose of gaining economic and political supremacy over the Philippines and the South China Seas. In all three cases, the actors, the diplomatic correspondence, the material aspects and the results differed profoundly. The article analyzes the role of individuals as intermediaries and translators while considering the social and cultural effects that these embassies had on the Sino-Spanish relations in Manila.

Abstract Many structures are subjected to varying forces, moving boundaries, and other dynamic conditions. Whether part of a vehicle, building, or active energy mitigation device, data on such changes can represent useful knowledge, but also presents challenges in its collection and analysis. In systems where changes occur rapidly, assessment of the system’s state within a useful time span is required to enable an appropriate response before the system’s state changes further. Rapid state estimation is especially important but poses unique difficulties. In determining the state of a structural system subjected to high-rate dynamic changes, measuring the frequency response is one method that can be used to draw inferences, provided the system is adequately understood and defined. The work presented here is the result of an investigation into methods to determine the frequency response, and thus state, of a structure subjected to high-rate boundary changes in real-time. In order to facilitate development, the Air Force Research Laboratory created the DROPBEAR, a testbed with an oscillating beam subjected to a continuously variable boundary condition. One end of the beam is held by a stationary fixed support, while a pinned support is able to move along the beam’s length. The free end of the beam structure is instrumented with acceleration, velocity, and position sensors measuring the beam’s vertical axis. Direct position measurement of the pin location is also taken to provide a reference for comparison with numerical models. This work presents a numerical investigation into methods for extracting the frequency response of a structure in real-time. An FFT based method with a rolling window is used to track the frequency of a data set generated to represent the range of the DROPBEAR, and is run with multiple window lengths. The frequency precision and latency of the FFT method is analyzed in each configuration. A specialized frequency extraction technique, Delayed Comparison Error Minimization, is implemented with parameters optimized for the frequency range of interest. The performance metrics of latency and precision are analyzed and compared to the baseline rolling FFT method results, and applicability is discussed.

A series of experiments investigated cognitive processes involved in listening to a piece of music, focusing in particular on the abstraction of surface features (here referred to as cues). Subjects listened to an unfamiliar piece in a familiar musical idiom, and their sensitivities to aspects of the just-heard piece were used to elucidate the nature of their representations of the piece in recent memory. The study also sought to assess the capacities of subjects to use any declarative knowledge of aspects of tonal structure that they possessed in organizing musical material. Three experiments made use of different procedures to address these issues, using either a single short tonal piece—Schubert's Valse sentimentale, D. 779, op. 50, no. 6—or a variant of this. The first two experiments used nonmusician subjects and examined (1) the cues abstracted in listening to the piece and (2) subjects' ability to identify the temporal location of segments of the piece after listening. The third experiment explored the constructional abilities of musician and nonmusician subjects, requiring them to create a coherent piece by ordering the segments that made up the original piece. The results of these experiments indicated that although the abilities of musicians differed from those of nonmusicians, both groups of subjects exhibited a weaker sensitivity to features of musical structure than to cues abstracted from the musical surface.

Contrast Enhanced Ultrasonography

We aim to investigate the hemodynamics in focal steatosis and focal spared lesion of the liver using contrast-enhanced ultrasonography (CEUS) with Sonazoid. The subjects were 47 patients with focal steatosis and focal spared lesion. We evaluated enhancement patterns (hyperenhancement, isoenhancement, and hypoenhancement) in the vascular phase and the presence or absence of a hypoechoic area in the postvascular phase for these lesions using CEUS. Of the 24 patients with focal steatosis, the enhancement pattern was isoenhancement in 19 and hypoenhancement in 5. Hypoechoic areas were noted in the postvascular phase in 3 patients. Of the 23 patients with focal spared lesions, the enhancement pattern was isoenhancement in 18 and hyperenhancement in 5. No hypoechoic areas were noted in the postvascular phase in any patient. The hemodynamics in focal steatosis and focal spared lesions in nondiffuse fatty liver can be observed using low-invasive procedures in real-time by CEUS. It was suggested that differences in the dynamics of enhancement in the vascular phase of CEUS were influenced by the fat deposits in the target lesion, the surrounding liver parenchyma, and the third inflow.
