American Entomologist • Winter 2008 Unlike pathway and multiaccess keys, which use diagnostic morphological characters, NemaScope uses point-and-click visual matching that allows users to navigate through a collection of images until images similar to specimens under investigation are found. High-definition multifocal images of genera provide the basis for the initial photos and can be viewed w...

Since the 1960's many authors accepted the triple constraints (time, cost, specification) as a standard measure of success and this still appears to be extremely important in evaluating the success of ICT projects. However, an ICT project cannot always be seen as a complete success or a complete failure. Moreover, the parties involved may perceive the terms “success” or “failure” differently. T...

Large public displays are becoming a ubiquitous resource in the urban environment. Interconnected over the Internet these hitherto isolated “ad displays” could become a novel and powerful communication medium – networked public displays. One example for such a novel type of communication is their use as community tools. Scattered across the urban landscape and equipped with additional sensors, ...

Click-through information is considered as a valuable source of users’ implicit relevance feedback. As user behavior is usually influenced by a number of factors such as position, presentation style and site reputation, researchers have proposed a variety of assumptions (i.e. click models) to generate a reasonable estimation of result relevance. The construction of click models usually follow s...

We provide an in-depth study of the security of click-based graphical password schemes like PassPoints (Weidenbeck et al., 2005), by exploring popular points (hot-spots), and examining strategies to predict and exploit them in guessing attacks. We report on both shortand long-term user studies: one labcontrolled, involving 43 users and 17 diverse images, the other a field test of 223 user accou...

Although motivated by both usability and security concerns, the existing literature on click-based graphical password schemes using a single background image (e.g., PassPoints) has focused largely on usability. We examine the security of such schemes, including the impact of different background images, and strategies for guessing user passwords. We report on both shortand long-term user studie...

introduction: preterm birth is a risk factor for a number of conditions that requires comprehensive examination. our study was designed to investigate the impact of preterm birth on the processing of auditory stimuli and brain structures at the brainstem level at a preschool age.   materials and methods: an auditory brainstem response (abr) test was performed with low rates of stimuli in 60 chi...

The conjugation of oligonucleotides with reporters is of great interest for improving their intrinsic properties or endowing new ones. In this context, we report herein a new procedure for the bis-labelling of oligonucleotides through oxime ligation (Click-O) and copper(I)-catalyzed alkyne-azide cycloaddition (Click-H). 5'-Azido and 3'-aldehyde precursors were incorporated into oligonucleotides...
