A pivotal paper by Atkinson and Haller in 1994[1] laid the groundwork for secure transmission over the Internet and Virtual Private Networks (VPNs) were born. Infonetics Research, Inc. projects the worldwide market for Virtual Private Networks to reach $32 billion by 2003.[2] There are two primary reasons for the growing interest in VPNs: the cost savings associated with replacing leased lines ...

In August of 1959, David B. Wake and I collected a specimen of Tantilla in the vicinity of Ruby, Santa Cruz County, Arizona, that exhibited several morphological characteristics unknown in species of Tantilla reported from the United States at that time. In 1962 I collected additional specimens of this species during the course of a herpetofaunal survey of the lowlands in southern Sonora and Si...

In our previous work, we have proposed a new VPN architecture for enabling user-based multiply associated VPNs. In this paper, we implement a prototype system of a VPN that enables users to be associated with multiple VPNs using existing network technologies for demonstrating the feasibility of our architecture and for clarifying the service image of a multiple association service. Our prototyp...

BACKGROUND Literature has identified detrimental health effects from the indiscriminate use of artificial nighttime light. We examined the co-distribution of light at night (LAN) and breast cancer (BC) incidence in Georgia, with the goal to contribute to the accumulating evidence that exposure to LAN increases risk of BC. METHODS Using Georgia Comprehensive Cancer Registry data (2000-2007), w...

Tumor therapy needs new approaches in order to improve efficacy and reduce toxicity of the current treatments. The acidic microenvironment and the expression of high levels of endogenous non-telomerase reverse transcriptase (RT) are common features of malignant tumor cells. The anti-acidic proton pump inhibitor Lansoprazole (LAN) and the non-nucleoside RT inhibitor Efavirenz (EFV) have shown in...

In this research, we propose an architectural solution to integrate the video voice over IP services in campus environment network and tested over LAN and WAN. Voice over IP technology has become a discussion issue for this time being. Today, the deployment of this technology on an organization truly can give a great financial benefit over traditional telephony. Therefore, this study is to anal...

With the growth of wireless technologies rapidly, there will be coexist heterogeneous wireless LANs environment within a few years. For example, there may be coexist current wireless LAN systems based widely available 802.11 and a wireless LAN system based proprietary wireless LAN standard with different AAA mechanisms such as RADIUS and Diameter. In case of being coexisted the heterogeneous wi...

Overconfidence is a well-established behavioral phenomenon that involves an overestimation of own capabilities. We introduce a model, in which managers and agents exert effort in a joint production, after the manager decides on the allocation of the tasks. A rational manager tends to delegate the critical task to the agent more often than given by the efficient task allocation. In contrast, an ...
