Decreased Choline Acetyltransferase (ChAT) brain level is one of the main biochemical disorders in Alzheimer's Disease (AD). In rodents, recent data show that the CHAT gene can be regulated by a neural restrictive silencer factor (NRSF). The aim of the present work was to evaluate the gene and protein expression of CHAT and NRSF in frontal, temporal, entorhinal and parietal cortices of AD patie...

Let's talk about the elephant in room. ChatGPT and other Large Language Models (LLM) along with their AI cousins focused on images, graphics, math, coding, audio are dominating our world of generating reports manuscripts. They can be immensely fun: I asked to write me song lyrics fuzzy logic various genres. wasn't crazy folk song, but really liked ChatGPT's blues its bluegrass rendition. And wh...

Chat language is often referred to as Computer-mediated communication (CMC). Most of the previous studies on chat language has been dedicated to collecting ”chat room” data as it is the kind of data which is the most accessible on the WEB. This kind of data falls under the informal register whereas we are interested in this paper in understanding the mechanisms of a more formal kind of CMC: dia...

Very often, when using a chat tool where more than one participant is talking simultaneously, it is difficult to follow the conversation, read all the different messages and work out who is talking to whom about what. This problem has been dubbed BChat Confusion.’’ This article investigates this problem in debate sessions in an online university course. Chat Confusion has been singled out as th...

Pattern recognition and classification are two of the key topics in computer science. In this paper a novel method for the task of pattern classification is presented. The proposed method combines a hybrid associative classifier (Clasificador Híbrido Asociativo con Traslación, CHAT, in Spanish), a coding technique for output patterns called one-hot vector and majority voting during the classifi...

The purpose of this research was to advance the understanding of the behavior of small groups in online chat rooms. The research was conducted using Internet chat data collected through planned exercises with recruited participants. Analysis of the collected data led to construction of preliminary models of social behavior in online discourse. Some of these models, e.g., how to effectively chan...

In this paper we report our effort to construct the first ever Indonesian corpora for chat summarization. Specifically, we utilized documents of multi-participant chat from a well known online instant messaging application, WhatsApp. We construct the gold standard by asking three native speakers to manually summarize 300 chat sections (152 of them contain images). As result, three reference sum...

The developmental and regional expression of choline acetyltransferase (ChAT) mRNA was examined in the rat brain and spinal cord by northern blot analysis and in situ hybridization. ChAT mRNA expression in the brain showed a biphasic increase during development, with a first peak at two weeks postnatally, a marked decrease by the third week, and a second increase between the third and fifth wee...
