Finite-element modeling and simulations of the intra-body communication used for biomedical monitoring

The finite-element modeling and simulations of the intra-body communication （IBC） were investigated to provide a theoretical basis for biomedical monitoring. A finite-element model for the whole human body was developed to simulate the IBC. The simulation of galvanic coupling IBC and electrostatic coupling IBC were implemented along with different signal transmission paths, and their attenuations were calculated. Our study showed that the position near the signal electrode had higher potential than other positions in the two types of IBC, while the potential generally decreased along the axis of the body parts. Both signal attenuations of the two types IBC increased with increasing signal transmission distance, and the electrostatic coupling IBC had comparatively higher receiving potential than the galvanic coupling IBC. The results indicated that the proposed modeling method could be used for the research of biomedical monitoring based on IBC technology.

Signal averaging for noise reduction in anesthesia monitoring and control with communication channels

This paper investigates impact of noise and signal averaging on patient control in anesthesia applications, especially in networked control system settings such as wireless connected systems, sensor networks, local area networks, or tele-medicine over a wide area network. Such systems involve communication channels which introduce noises due to quantization, channel noises, and have limited communication bandwidth resources. Usually signal averaging can be used effectively in reducing noise effects when remote monitoring and diagnosis are involved. However, when feedback is intended, we show that signal averaging will lose its utility substantially. To explain this phenomenon, we analyze stability margins under signal averaging and derive some optimal strategies for selecting window sizes. A typical case of anesthe-sia depth control problems is used in this development.

Towards Developing Communication Strategies for HIV/AIDS Control among the Scheduled Tribes and Scheduled Castes Women in Three Northeastern States of India

HIV/AIDS spread has opened a Pandora of medical and health problems apart from creating serious socio-psychological trauma for the victims and their families. Despite the governmental effort to curve the growing infection, very little success has been achieved. The northeastern region of India presents a very peculiar situation due to recurrent insurgency in all its states for long time and thus it became instrumental in paralyzing the social and health machineries to an extent, which still deteriorated the futile national effort to check the deadly infection. The study tried to understand the level of awareness and correct knowledge among the underprivileged scheduled tribes and scheduled castes women in the age group 15 -44 by exploring data from district level of Rapid Household Reproductive and Child Health Project Phase I (1998) and Phase II (1999) for Assam, Manipur and Nagaland and suggested a strategy to control the infection in the region. It is found that HIV/AIDS awareness was 59% among the women in all the three states with very few among them who had correct understanding of its prevention. A pronounced difference in the level of awareness was observed with respect to age, economy and residential status of the respondents.

In the process of Chinese Literature’s “Going-out” project, it istypical of the dilemma faced by the external translation and dissemination of modernChinese literature. The Renditions Series serves as a classical case of providing aneffective model of “literature’s overseas distribution”. The successful experience of itstranslating-cum-disseminating model can be concluded as follows: all the translatorsare from China and overseas with cross-cultural background; the selection oftranslation is stylistically far-ranging among the Mainland, Taiwan and Hong Kong,and feminine literature in modern China is highly valued; translating method aims atconvoying the original literary aesthetics, and disseminating channels are manifold;the foreign recipients are common and professional readers; the eminent effects canbe proved by its considerable sales, library collections and acceptance in the targetcountries and regions. From the successful model of translation of Renditions Series,five implications can be made out for the modern Chinese literature’s “Going-global”:domestic and overseas translators cooperate well with all-round cultural identities; theselection holds onto diversification and literary character; various spreading channelsshould be broadened; target readers should be accurately located and continuouslywidened; translating and disseminating effects can be focused on and analyzed, so asto adjust and improve the corresponding sections in the model.
