Excised root tips from dark-grown mung bean seedlings (Phaseolus aureus) that adhere to a negatively charged glass surface when irradiated with red light and release when irradiated by far-red light develop a positive bioelectric potential (about 1.0 millivolt) at the tip in red light and a negative bioelectric potential in far-red light. The sign of the bioelectric potential was repeatedly pho...

Change-Point (CP) detection has attracted considerable attention in the fields of data mining and statistics; it is very meaningful to discuss how to quickly and efficiently detect abrupt change from large-scale bioelectric signals. Currently, most of the existing methods, like Kolmogorov-Smirnov (KS) statistic and so forth, are time-consuming, especially for large-scale datasets. In this paper...

Tissues like bone and cartilage are remodeled dynamically for their functional requirements by signaling pathways. The signals are controlled by the cells and extracellular matrix and transmitted through an electrical and chemical synapse. Scaffold-based tissue engineering therapies largely disturb the natural signaling pathways, due to their rigidity towards signal conduction, despite their th...

One of the most desirable characteristics of an intelligent interactive system is its capability of interacting with users in a natural way. An example of such a system is the embodied conversational agent (ECA) that has a humanoid aspect and the capability of communicating with users through multiple modalities such as voice, gesture, facial expressions, that are typical of human-human communi...

In our daily lives, we form some impressions of other people. Although those impressions are affected by many factors, face-based affective signals such as facial expression, facial attractiveness, or trustworthiness are important. Previous psychological studies have demonstrated the impact of facial impressions on remembering other people, but little is known about the neural mechanisms underl...

BACKGROUND--Bronchial epithelial function after heart-lung transplantation (HLT) for cystic fibrosis (CF) may be affected by the original disease as well as other factors such as prolonged organ ischaemic time, the interruption of bronchial arterial and lymphatic supply, infection, rejection, and cyclosporin. In vitro measurement of the bioelectric properties of the bronchial mucosal lining may...

Despite widespread interest in quality signals, a broad understanding of quality that incorporates information about signals used in a variety of contexts remains elusive. For example, relatively little is known about arbitrary signals of quality used during aggressive competition (badges of status). Recently, a new badge of status was found: black facial patterns in Polistes dominulus wasps. P...

The human face is involved in an impressive variety of different activities. It houses the majority of our sensory apparatus—eyes, ears, mouth, and nose— allowing the bearer to see, hear, taste, and smell. Apart from these biological functions, the human face provides a number of signals essential for interpersonal communication in our social life. The face houses the speech production apparatu...
