While attracting attention is one of the prime goals of content providers, the conversion of that attention into revenue is by no means obvious. Given that most users are used to consuming web content for free, a content provider faces a dilemma. Since the introduction of advertisements or subscription fees will be construed by users as an inconvenience which may deter them from using the websi...

Sex chromosomes--particularly the human Y--have been a source of fascination for decades because of their unique transmission patterns and their peculiar cytology. The outpouring of genomic data confirms that their atypical structure and gene composition break the rules of genome organization, function, and evolution. The X has been shaped by dosage differences to have a biased gene content and...

Question detection serves great purposes in the cQA question retrieval task. While detecting questions in standard language data corpus is relatively easy, it becomes a great challenge for online content. Online questions are usually long and informal, and standard features such as question mark or 5W1H words are likely to be absent. In this paper, we explore question characteristics in cQA ser...

Six anaesthetized, paralyzed, hypothermic (30° C) dogs were hyperventilated for 2 hours. During the final 30 minutes, die inspired mixture was altered from oxygen to air. The rates at which alveolar and arterial oxygen concentrations approached their new steady state values were represented by the half-times (t£) of 0.19 and 0.26 minutes, respectively. The turnover rate in venous blood oxygen c...

Concept extraction is a primary subtask of ontology construction. It is difficult to extract new concepts from traditional text corpus. Moreover, building a single ontology for multiple-topic corpus may lead to misconception. To deal with these problems, this paper proposes a novel framework to extract topical key concepts from folksonomy. Folksonomy is a valuable data source due to real-time u...

Moving object detection is a key to intelligent video analysis. On the one hand, what moves is not only interesting objects but also noise and cluttered background. On the other hand, moving objects without rich texture are prone not to be detected. So there are undesirable false alarms and missed alarms in many algorithms of moving object detection. To reduce the false alarms and missed alarms...

The ac conductance in granular insulating Co-ZrO2 thin films prepared by pulsed laser deposition is systematically studied as a function of the Co volume content x. An absorption phenomenon at low frequencies that mimics the universal response of disordered dielectric materials is observed in the range of metal content below the Co percolation threshold xp 0.35 in the so-called dielectric regim...
