Variation in expression and function of the human 5-hydroxytryptamine (5-HT, serotonin) transporter (SERT) is associated with psychiatric disturbances [1,2]. Such associations remain controversial however, and the underlying neurobiology is not understood. One point of discordance is that whilst SERT levels seem to inversely correlate with brain 5-HT levels, the relationship between SERT levels...

Block-based transform coding is the most popular approach for image and video compression. The objective measurement of blocking artifacts plays an important role in the design, optimization, and assessment of image and video coding systems. This paper presents a new algorithm for measuring blocking artifacts in images and videos. Instead of using the traditional pixel discontinuity along the b...

The "intentionality bias" refers to our automatic tendency to judge other people's actions to be intentional. In this experiment we extended research on this effect in two key ways. First, we developed a novel nonlinguistic task for assessing the intentionality bias. This task used video stimuli of ambiguous movements. Second, we investigated the relationship between the strength of this bias a...

This paper presents a method for evaluating a communication situation in a multimodal multi-user virtual environment. In the evaluation both the quality of the communication and the user experience will be addressed. Twenty-four subjects participated in the experiment which was carried out in a virtual reality CAVE. Two different sound presentations were used (Diotic and Binaural) and two diffe...

in this paper, we propose a new full-fuzzy video ratecontrol algorithm (rca) for variable bit rate (vbr) videoapplications. the proposed rca provides high qualitycompressed video with a low degree computational complexity.by controlling the quantization parameter (qp) on a picturebasis, it produces vbr video bit streams. the proposed rcahas been implemented on the jm h.264/avc video codec andth...

While mechanisms exist to evaluate the user-perceived quality of video streamed over computer networks, there are few good mechanisms to do so in real time. In this paper, we evaluate the feasibility of predicting the stream quality of partial portions of a video stream based on either complete or incomplete information from previously rated streams. Using stream state information collected fro...

A 25-year-old man presented with a 3-month history of gradually progressive right side hemiparkinsonism. On examination his Unified Parkinson Disease Rating Scale motor score was 12 on the right side. There were no other abnormal neurologic findings. Brain MRI and angiography showed a giant thrombus containing aneurysm of the left middle cerebral artery compressing the left basal ganglia (figur...

An innovative inspection method to assess the condition of sewer pipes is proposed in this paper. The standard sewer inspection technique, based on closed-circuit television systems, has a very poor performance. A video camera is mounted on a robot and the video recording is provided off-line to an engineer that classifies the potential defects. The focus of the research is the automated identi...

This paper describes a new video-based observation method aimed to assess musculoskeletal load in kitchen work, aspects of its repeatability and validity, and problems confronted by the observers. Two pairs of researchers observed individually 117 video clips recorded in kitchens. Interobserver repeatability was assessed by computing the proportion of agreement and weighted kappa values (kappa(...
