Twitter has become the de facto information sharing and communication platform. Given the factors that influence language on Twitter – size limitation as well as communication and content-sharing mechanisms – there is a continuing debate about the position of Twitter’s language in the spectrum of language on various established mediums. These include SMS and chat on the one hand (size limitatio...

The lack of visibility in text-based chat can hinder communication, especially when nonverbal cues are instrumental to the production and understanding of messages. However, communicating rich nonverbal cues such as facial expressions may be technologically more costly (e.g., demand of bandwidth for video streaming) and socially less desirable (e.g., disclosing other personal and context inform...

There is increasing interest in localizing nerves in the intestine, especially specific populations of nerves. At present, the usual histochemical marker for cholinergic nerves in tissue sections is acetylcholinesterase activity. However, such techniques are applicable only to frozen sections and have uncertain specificity. Choline acetyltransferase (ChAT) is also present in cholinergic nerves,...

The Copying Approach to Tabling, abbrv. CAT, is an alternative to SLG-WAM and based on total copying of the areas that SLG-WAM freezes to preserve execution states of suspended computations. The disadvantage of CAT as pointed out in a previous paper is that in the worst case, CAT must copy so much that it becomes arbitrarily worse than SLG-WAM. Remedies to this problem have been studied, but a ...

In this paper, we suggest a list of high-level features and study their applicability in detection of cyberpedophiles. We used a corpus of chats downloaded from www.perverted-justice.com and two negative datasets of different nature: cybersex logs available online and the NPS chat corpus. The SVM classification results show that the NPS data and the pedophiles’ conversations can be accurately d...

We evaluate several different overlay routing structures for supporting interactivity features in End Sysytem Multicast. Interactivity features include low-bandwidth textual chat, as well as higher-bandwidth audio conferencing and immersive audio applications. Overlays are evaluated using real interaction patterns seen in IRC, as well as real join and leave patterns from an ESM video broadcast....

On-line chat is becoming more popular for both work and leisure. Unfortunately, the chat format is quite constrained in its ability to convey many important pieces of non-verbal information. We present a new system that uses dynamic text with numerous interactive techniques to effectively communicate nonverbal information. We created a number of easily recognizable animation types to show emoti...

An ethanolic extract of Allium tuberosum Rottl. demonstrated potent choline acetytrasferase (ChAT) activating activity (45%) among 30 screened Korean edible plants. The ChAT activator of A. tuberoum Rottl. was purified and identified as ferulic acid [4-hydroxy-3-methoxycinnamic acid] via silica-gel open-column chromatography, HPLC, EI-MS, and 1H/13C-NMR. The ferulic acid from A. tuberoum Rottl....

When trying to identify the author of a book, a paper, or a letter, the object is to detect a style that distinguishes one author from another. With recent developments in artificial intelligence, chat bots sometimes play the role of the text authors. The focus of this study is to investigate the change in chat bot linguistic style over time and its effect on authorship attribution. The study s...

Mostly, the conversations taking place in chat mediums bear important information concerning the speakers. This information can vary in many fields such as tendencies, habits, attitudes, guilt situations, and intentions of the speakers. Therefore, analysis and processing of these conversations are of much importance. Many social and semantic inferences can be made from these conversations. In d...
