We propose a Multi-model CAPTCHA that is composed of one sentence with typo and multiple pictures. This utilizes human's three abilities (inferring the meaning typo, understanding pictures, linking corresponding picture), it based on hypothesis, "the longer time could be for machine to link picture (= shorter linking, higher probability human)." found findings from our experiment: (1) Examinees...

Sleep benefits the consolidation of emotional memories, and this influence is commonly attributed to the rapid eye movement (REM) stage of sleep. However, the contributions of sleep stages to memory for an emotional episode may differ for the event per se (i.e., item memory), and the context in which it occurred (source memory). Here, we examined the effects of slow wave sleep (SWS) and REM sle...

For the past few years, a joint ISO/CCITT committee known as JPEG (Joint Photographic Experts Group) has been working to establish the first international compression standard for continuous-tone still images, both grayscale and color. JPEG's proposed standard aims to be generic, to support a wide variety of applications for continuous-tone images. To meet the differing needs of many applicatio...

Two experiments investigated the processes underlying the picture superiority effect on recognition memory. Studied pictures were associated with higher accuracy than studied words, regardless of whether test stimuli were words (Experiment 1) or pictures (Experiment 2). Event-related brain potentials (ERPs) recorded during test suggested that the 300-500 msec FN400 old/new effect, hypothesized ...

Whether words are or are not activated within the lexicon of the nonused language is an important question for accounts of bilingual word production. Prior studies have not led to conclusive results, either because alternative accounts could be proposed for their findings or because activation could have been artificially induced by the experimental paradigms. Moreover, previous data only invol...

There is a need to use selected pictures with pure emotion as stimulation or treatment media for basic and clinical research. Pictures from the widely-used International Affective Picture System (IAPS) contain rich emotions, but no study has clearly stated that an emotion is exclusively expressed in its putative IAPS picture to date. We hypothesize that the IAPS images contain at least pure vec...

This paper discusses current video compression techniques and presents an overview of the existing video compression standards and standards to be. The standards discussed here are standards defined by dedicated committees as well as de facto standards.

BACKGROUND Germ line mutations in mismatch repair genes underlie Lynch syndrome and predispose carriers for colorectal carcinoma and malignancies in many other organ systems. CASE PRESENTATION A large Lynch syndrome family with 15 affected family members and involvement in 7 organs is reported. It illustrates a lack of awareness and knowledge about this hereditary tumor syndrome among doctors...

The role of visual stimuli in the organization and recall of social information was investigated in a study that presented photographs of stimulus persons along with verbal trait descriptors. Paired with four trait descriptors of each stimulus person, subjects saw either no picture, one trait-unrelated picture, four trait-unrelated pictures, or four trait-related pictures. These conditions perm...

In accordance with the emotional priming hypothesis, emotions seem to modulate pain perception and pain tolerance thresholds. To further evaluate this association, event-related brain potentials (ERPs) elicited by painful and nonpainful electrical stimuli during processing of positive, neutral, and negative valenced pictures were recorded from 30 healthy volunteers. Valence of pictures affected...
