The authors examined the correlation between solar activity (sunspot numbers) and 96050 psychiatric admissions between July 1984 and December 1993, Victoria, Australia. Calculation of the Pearson correlation coefficient gave a value of 0.399 (P value; 0.0001). This value however, may be an artefact of autocorrelations within the two series rather than a relationship between them as the Pearson correlation does not account for the serial nature of the data. To overcome this problem the authors calculated the prewhitened cross-correlation between the series and tested whether they were uncorrelated. The test was significant (P value; 0.006), which gives strong evidence for a relationship between sunspot number and psychiatric admissions.

Medicine has long been challenged to detect disease before it can do irreversible damage, usually by means of invasive tests after the presentation of symptoms. This paper introduces a unique diagnostic tool, the Instant Kirlian Diagnostic System (IKiDS) which derives from the work of the Kirlians of Russia in 1939. It delineates both the disease process and its energetic precursors in the human energy field, allowing for treatment and lifestyle changes before real damage occurs. IKiDS utilises a sensor, high voltage electronics and computer software to "capture" an energy discharge from the fingertips which contains valuable diagnostic information. The research summary is based on analysis of over 1000 sets of prints. Whilst some diagnostic puzzles remain, it is clear that IKiDS has impressive diagnostic and evaluative capabilities. Furthermore, it is accurate, user friendly and offers a complete picture of the physical, mental and emotional condition in "real time". Future research directions are indicated.

Radial pressure waves (RPWs) and carotid pressure waves (CPWs) were recorded using applanation tonometry in 6 healthy subjects (5M, 1F, all aged 21 yrs) at rest as well as after a vasodilator agent (sublingual glyceryl trinitrate [GTN] spray). For each subject, transfer functions between radial and carotid pressure waves were calculated by a nonparametric Fourier method. Using the transfer functions, CPWs were reconstructed from RPWs and compared to tonometrically recorded CPWs. The transfer functions accurately predicted CPWs at rest, however, post-GTN, there were significant differences between reconstructed and recorded CPWs. The timing of peak systolic pressure, as predicted by the reconstructed CPWs, was underestimated by 0.3% at rest and was overestimated by 2.3% post-GTN spray.

Inferior colliculus (IC) units have a significantly lower stimulus threshold when driven with a cochlear implant using bipolar stimuli at high (2 k pulses/s) compared to low (125 pulse/s) pulse rates. At high pulse rates temporal summation is used to explain this threshold shift.

Pulse pressure waves (PPWs) were recorded from the radial artery using photoplethysmography in 7 healthy subjects (6M, 1F, mean age 23 yrs) at rest every 3 hours between 9 am and 6 pm. Analysis of variations of PPWs included sum of square differences between waves, ANOVA and spectral analysis of the components of waves. PPWs recorded at 9am were not significantly different to PPWs recorded at 6 pm, however, PPWs between each other time period were significantly different, with the largest difference occurring between 9 am and 3pm. There was also some variation in the frequency components of the PPWs with an increase in higher frequency components as the day progresses. The finding of this study supports the suggestion within TCM that there are changes in PPW throughout the day.

In this study we use the adapted wavelet transform methods (wavelet and cosine packets) for spectral analysis of bioelectric signals. These methods have recently been introduced for analysis of non-stationary signals. Using recordings of the heart rate variability in twenty healthy subjects, the estimated power in different frequency bands is compared to results based on the classical methods: fast Fourier transform and autoregressive modelling. The results showed that cosine packets gave similar results to classical methods, and may be preferred to characterise the rhythmic components in the recorded signals. On the other hand, the non-stationary fluctuations, i.e., the "trend", was efficiently decomposed using the wavelet transform method.

Registration of increased QTc interval duration and QT and QTa interval dispersion in patients with high risk of sudden death as compared to the patients without it according to the results of programmed ventricular stimulation (469.5/spl plusmn/43.2 and 435.5/spl plusmn/29.6 ms, 60.2/spl plusmn/23.6 and 43.8/spl plusmn/11.3 ms, 56.71/spl plusmn/27.0 and 33.7/spl plusmn/14.5 ms, respectively) demonstrate the efficacy of this non-invasive method in identification of high-risk subgroup of post-myocardial infarction patients.

A small ion-free solution-perfusion chamber has been developed to continuously observe the single sweat gland activity (SSGA) at the skin surface by conductivity measurement. The chamber has a very small open space of 0.2 mm/sup 2/ at the bottom and has a transparent view field. Ag-electrodes were installed inside the chamber and by perfusing purified water through the chamber at a constant flow rate conductivity was measured before and just after washed out sweat. Single sweat pores were visualized by starch/iodine method and magnifying lens. SSGA was observed by attaching the chamber on single sweat pores at palm and finger tip skin surface when the subjects were sitting resting position and doing hand (non-experimental) grasping with a dynamometer. Different types of continuous SSGA were observed from sweat pores.

Although the sensing of chemical signals is extremely important for most living creatures there have been few attempts to transfer this capability to robotic systems. In order to operate effectively in the variable and unstructured real world environment insects employ many strategies. Generating and detecting odours is the basis of several of these strategies. It seems certain that similar techniques can be implemented to improve the competence of robotic systems. This paper describes the development of sensors and algorithms which will allow odour sensing to be applied to robotic systems. Currently a robotic and has been built to act as a testbed for the odour sensors and to investigate biologically inspired control algorithms. Design of this robot and results of odour trail following experiments are presented in this paper.

Acupuncture points and meridians have been shown to have distinct electrical characteristics. Acupuncture points have been found to have lower electrical impedance and acupuncture meridians represent low resistance pathways. The authors examined the spectral characteristics of a section of the large intestine acupuncture meridian in 10 healthy volunteers by inserting a broad-spectrum pulse at one point and detecting the output response further along the meridian. Analysis of the meridian transfer function revealed characteristic resonant frequencies that strongly coincide with the spectral components of Schumann resonances and the human EEG.
