Trust models in the literature of MANETs commonly assume that packets have different security requirements. Before a node forwards a packet, if the recipient's trust level does not meet the packet's requirement level, then the recipient must perform certain security association procedures, such as re-authentication. We present in this paper an analysis of the epidemic broadcast delay in such context. The network, mobility and trust models presented in this paper are quite generic and allow us to obtain the delay component induced only by the security associations along a path. Numerical results obtained by simulations also confirm the accuracy of the analysis. In particular, we can observe from both simulation's and analysis results that, for large and sparsely connected networks, the delay caused by security associations is very small compared to the total delay of a packet. This also means that parameters like network density and nodes' velocity, rather than any trust model parameter, have more impact on the overall delay.

This paper examines the effects of global liquidity expansion on advanced and emerging economies by using panel VAR methodology. The results show that global liquidity expansion tends to boost economy by increasing GDP growth and stock prices. However, we find that the effects are asymmetric. The effects of global liquidity on GDP and stock prices are greater and more persistent in emerging economies than in liquidity recipient advanced economies. Moreover, global liquidity appreciates emerging economies' exchange rates more persistently than those of advanced economies. Lastly, while global liquidity expansion increases foreign portfolio investment inflows to Asian countries and liquidity recipient advanced economies, there is no evidence for Latin American countries.

Development assistance plays an important role in contributing to the development process of Cambodia. The top bilateral donors, China, Japan, and Korea provide ODA to Cambodia in different characteristics and from different perspectives. This study tries to pull out some implications for Cambodia as recipient and for donors in order to achieve the development of Cambodia's economy-effectively by using the ODA. As a viewpoint, ODA structure emphasizes the intention of donors, either for their self-interest and benefit or for achieving MDGs. China's ODA to Cambodia seems to distort the ODA allocation by other donors with unconditional loans or loans with conditionality focusing only on infrastructure. Cambodia benefits from the better infrastructure, but it has to pay the price set by China, even for concessional loans. The driving interests of Japan and Korea are more influenced by their national policy goals and the expected perceptions of their voters. The aid projects should at least catch the attention of national media or win obvious and unbiased support from the suffering people in the recipient countries.

Industrial Technology Development Program enables the recipient to set up technology infrastructure and to facilitate technology diffusion. In return, government charges royalty from the program recipient. However, the current royalty system is not in the effective form. This study analyzes the various aspects of royalty collection methods applied to the Industrial Technology Development Program and recommend the following: (1) employ the combination of fixed amount royalty and running royalty with predetermined portion of revenue generated, (2) adjust the royalty collection duration by applying product life cycle, and (3) devise new program to link extra-gain from royalty collection with commercialization and other means to increase the effectiveness of research and development activities.

There is an intuitive connection between signcryption and key agreement. Such a connector may lead to a novel way to construct authenticated and efficient group key agreement protocols. In this paper, we present a primary approach for constructing an authenticated group key agreement protocol from signcryption. This approach introduces desired properties to group key agreement. What this means is that the signcryption gives assurance to a sender that the key is available only to the recipient, and assurance to the recipient that the key indeed comes from the sender. Following the generic construction, we instantiate a distributed two-round group key agreement protocol based on signcryption scheme given by Dent [8]. We also show that this concrete protocol is secure in the outsider unforgeability notion and the outsider confidentiality notion assuming hardness of the Gap Diffie-Hellman problem.

This study describes a patient with insufficient vestibular depth who was operated with a vestibuloplasty using a non-eugenol-based non-zinc oxide oral dressing material. Partial thickness flap was elevated on recipient. After stabilization of apical positioned flap, the dressing material was applied on the recipient site with additional fixation by suture. The patient presented minimal discomfort such as in pain, food impaction and management of oral hygiene. Adequate vestibular depth without relapse was observed until 4 weeks after surgery. The vestibuloplasty with the oral dressing material may be an option for obtaining proper vestibular depth without complications.

In lung transplantation surgery, the pulmonary veins are anastomosed by connecting each atrium of the donor and recipient. However, occasionally the recipient's left atrium is not suitable for anastomosis for various reasons. In these cases, several techniques for atrial anastomosis have been introduced, but these are somewhat complicated for an inexperienced surgeon. Here, we propose a new atrial anastomosis technique that is easier and safer than previously introduced techniques.

This study examines factors influencing gift sharing on social media. An online survey gathered data from American adults. It investigates how motivations for social media content posting, gift attributes, giver characteristics, and recipient reactions affect gift-sharing behavior. Findings show self-expression motives in content posting drive sharing, while social interaction motives do not. Gifts perceived as experiential and expensive are more likely to be shared. Recipient-centric gifts positively influence gift sharing, while giver-centric gifts hinder sharing. Attitude towards the gift predicts sharing, while appreciation does not. The study enhances understanding of gift sharing on social media and offers marketing insights for leveraging this behavior.
