Technology, investment and trade: empirical evidence for five Asia-Pacific countries

Traditional models of international trade flows find that prices explain significant growth in export market shares. In the new international trade theory non-price factors are seen to be of great importance for the explanation of trade. Following Magnier and Toujas-Bernate (1994), this study introduces non-price factors, namely gross fixed investment and technology (number of patents accepted), into the export market share equation. Empirical estimation is carried out on five Asia-Pacific countries for the period 1978 to 1993. Results are similar to those of Magnier and Toujas-Bernate (1994) for the OECD, which show that non-price factors have played an important role in determining export market share during the last decade.

Open Cross-Domain Visual Search

This paper addresses cross-domain visual search, where visual queries retrieve category samples from a different domain. For example, we may want to sketch an airplane and retrieve photographs of airplanes. Despite considerable progress, the search occurs in a closed setting between two pre-defined domains. In this paper, we make the step towards an open setting where multiple visual domains are available. This notably translates into a search between any pair of domains, from a combination of domains or within multiple domains. We introduce a simple -- yet effective -- approach. We formulate the search as a mapping from every visual domain to a common semantic space, where categories are represented by hyperspherical prototypes. Open cross-domain visual search is then performed by searching in the common semantic space, regardless of which domains are used as source or target. Domains are combined in the common space to search from or within multiple domains simultaneously. A separate training of every domain-specific mapping function enables an efficient scaling to any number of domains without affecting the search performance. We empirically illustrate our capability to perform open cross-domain visual search in three different scenarios. Our approach is competitive with respect to existing closed settings, where we obtain state-of-the-art results on several benchmarks for three sketch-based search tasks.Comment: Accepted at Computer Vision and Image Understanding (CVIU

Review Article: A trends of Salmonella and antibiotic resistance

Salmonellosis has become a major problem in developed and developing countries. It also represents an important public health concern worldwide.  As such, due to intense interest Salmonella research has gained great concern from scientific communities as well as the general public.  The purpose of this review is to discuss the historical perspective, classification and nomenclature, antibiotic and antimicrobial definition, mechanism of antibiotic resistance, integrons and antibiotic resistance Salmonella

Secure Vehicular Communication Systems: Implementation, Performance, and Research Challenges

Vehicular Communication (VC) systems are on the verge of practical deployment. Nonetheless, their security and privacy protection is one of the problems that have been addressed only recently. In order to show the feasibility of secure VC, certain implementations are required. In [1] we discuss the design of a VC security system that has emerged as a result of the European SeVeCom project. In this second paper, we discuss various issues related to the implementation and deployment aspects of secure VC systems. Moreover, we provide an outlook on open security research issues that will arise as VC systems develop from today's simple prototypes to full-fledged systems

Effect of crumb rubber on mechanical properties of multi-phase syntactic foams

Syntactic foam is a lightweight and strong material which can be used in marine and aeronautical applications. However, the brittleness of the material limits its application to a broader range. Adding crumb rubber to the syntactic foam can increase its energy absorption capacity. The effect of crumb rubber on the fracture toughness and energy absorption capacity of 2-phase and 3-phase syntactic foam is evaluated under both static and impact loads. The experimental results have shown that the fracture toughness of the 2-phase rubberized syntactic foam increased by 8% while an increase of 22% of its fracture energy was observed. Under quasi-static loads, the 3-phase rubberized syntactic foam showed decreases in the compressive strength and elastic modulus but an increase in the energy absorption capacity as compared to the syntactic foam without crumb rubber. In addition, the impact energy absorption of the 3-phase rubberized syntactic foam increased by 24% as compared to that of the 3-phase syntactic foam without crumb rubber
