In the equatorial stratosphere, the zonal wind direction changes from westward to eastward and vice versa at intervals of from less than two to about three years and centered at about 28 months (Reed et al., 1961; Veryard & Ebdon, 1961). This phenomenon is called the quasibiennial oscillation (QBO) from the length of its period (Angell & Korshover, 1964). The QBO initiates in the upper stratosp...

To date, there has been no report of coinfection of human WU polyomavirus (WUPyV) with norovirus (NV). WUPyV has been detected in stool indicating pathogenicity of the gastrointestinal tract. Feces from 110 children (58 males, 52 females) with acute gastroenteritis admitted to Wei-Gong Memorial Hospital, Taiwan were screened for the presence of WUPyV and NV GII by PCR and RT-qPCR, respectively ...

Abstract Multi-authenticated encryption is an important message transmission technique, which can send message in a secure and authentic way, and allows a group of signers to cooperatively produce a valid authenticated ciphertext so that only the specific recipient can recover the message and verify the signature. In 2008, Wu et al. proposed a convertible multi-authenticated encryption scheme. ...

In this paper, we emphasize that choice sets generated by a search process have two properties: first, they are limited; second, they are endogenous to preferences. Both factors lead to biased estimates in a static demand framework that takes choice sets as given. To correct for this bias, we estimate a structural model of search for differentiated products, using a unique dataset of consumer o...

To send the message to the recipient securely, authenticated encryption schemes were proposed. In 2008, Wu et al. [T.S. Wu, C.L. Hsu, K.Y. Tsai, H.Y. Lin, T.C. Wu, Convertible multi-authenticated encryption scheme, Information Sciences 178 (1) 256–263.] first proposed a convertible multi-authenticated encryption scheme based on discrete logarithms. However, the author finds that the computation...

in design and optimization process of laminated composite structures, the number of layers, layer angles, stacking sequence, material types and etc should be specified. each of aforesaid parameters can be applied as a design variable. in this paper the target is to minimize the weight of laminated composite pin loaded structures. the laminated composite structures are designed based on the load...

In this paper, analytical and 3D numerical models are developed to investigate the mechanical behavior of sandwich pipe under internal pressure loading. The suggested provide an exact solution for stresses, strains displacement on pipe, which is made epoxy material core layer reinforced materials with alternate-ply skin layers. aim analysis evaluate potential applications jute pineapple leaf fi...

Ice loads are an important and decisive factor for the safe operation of offshore wind turbines (OWTs). In severe environment load cases, it shall lead to prominent ice-induced vibration fatigue failure OWT structures. Based on cohesive element method (CEM) considering pile–soil interaction used by nonlinear distributed springs, full model ice monopile structure with ice-breaking cone in a cold...

This paper presents a comparative study of the geometrical optimization mechanical wedge–barrel anchors for prestressed carbon fiber-reinforced polymer (CFRP) rods. Various anchor configurations were simulated using three-dimensional finite-element (FE) models. The FE models validated draw-ins wedges, which measured in static tensile tests. consisted steel barrel and aluminum taking advantage p...
