    The Neuroanatomic Basis of the Acupuncture Principal Meridians

    No full text
    Acupuncture involves treating illness by inserting needles at specified body locations (acupoints). The Principal meridians are pathways that join acupoints with related physiologic effects. Despite nearly 5000 years of continuous clinical study, an accepted anatomic or physiologic basis for acupuncture's clinical effects has remained elusive. Some acupoints overlie peripheral nerves, and fMRI studies demonstrate that acupoints have specific effects on central nervous system processing. Traditional Chinese Medicine (TCM) founders described the body's viscera based on anatomic dissections yet not a discrete nervous system. By applying computer graphics and virtual human imaging techniques to human developmental neuroanatomy, this paradox may potentially be explained: acupuncture Principal meridians likely are TCM's representation of the nervous system. This neuroanatomic model of the Principal meridians is consistent with acupuncture's known neurophysiologic effects, and may allow 5 millennia of accumulated TCM observations regarding human health and illness to be understood in modern anatomic and physiologic terms

    Fibromyalgia: A Unifying Neuroendocrinologic Model for Understanding Its Pathophysiology

    No full text
    Fibromyalgia is believed to affect at least 2% of the population. Despite advances in the scientific understanding of the derangements of central and peripheral pain processing mechanisms in fibromyalgia, no current models of its pathophysiology account for the other clinical conditions associated with it such as fatigue, migraine headache, irritable bowel syndrome, and sleep cycle abnormalities. A neuroendocrinologic model of fibromyalgia is presented that accommodates both its known central and peripheral pain mechanisms as well as the myriad of hormonal, visceral, and psychological symptoms associated with that disorder. This model also provides a unifying pathophysiologic basis of fibromyalgia and chronic muscle pain, and offers the potential for developing new avenues of research and treatment for these enigmatic, frequently disabling medical conditions

    Using gravitational lens geometry to measure cosmological parameters

    No full text
    Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Physics, 2004.Includes bibliographical references (leaves 69-73).We develop a technique for measuring cosmological parameters ([omega]M and w) using gravitational lens geometry, source and lens redshifts, and the velocity dispersion of the lensing galaxy. This technique makes use of the relation [theta][sub]E = 4[pi]... where the critical radius [theta][sub]E and the one-dimensional velocity dispersion of the lensing galaxy [sigma]v are observable and the angular diameter distance ratio D[sub]LS/D[sub]S is related to the source and lens redshifts Z[source] and Z[lens] through the cosmological model. We assess the feasibility of this technique by examining the dependence of that ratio on cosmological parameters, doing a Monte Carlo simulation with a singular isothermal sphere lens galaxy, and estimating the error due to the asymmetry of real lenses. We conclude that the method is feasible with a large lens sample and a nearly circular projected mass distribution. We expect errors of less than 0.1 in [omega]M for a flat universe with a cosmological constant and a lens sample selected so that the axial ratio f > 0.8 for each lens.by Susan E. Dorsher.S.B

    Characterization of the seismic environment at the Sanford Underground Laboratory, South Dakota

    No full text
    An array of seismometers is being developed at the Sanford Underground Laboratory, the former Homestake mine, in South Dakota to study the properties of underground seismic fields and Newtonian noise, and to investigate the possible advantages of constructing a third-generation gravitational-wave detector underground. Seismic data were analyzed to characterize seismic noise and disturbances. External databases were used to identify sources of seismic waves: oceanwave data to identify sources of oceanic microseisms, and surface wind-speed data to investigate correlations with seismic motion as a function of depth. In addition, sources of events contributing to the spectrum at higher frequencies are characterized by studying the variation of event rates over the course of a day. Long-term observations of spectral variations provide further insight into the nature of seismic sources. Seismic spectra at three different depths are compared, establishing the 4100-ft level as a worldclass low seismic-noise environment

    Acupuncture Point Localization Varies Among Acupuncturists

    No full text
    Background: Studies assessing the point-specific effect of acupuncture or the characteristics of acupuncture points (APs) tend to yield inconclusive results. In order to identify a possible confounding factor, we aimed to examine the variability in AP localization by means of a survey. Material and Methods: Attendees of the 14th ICMART (International Council of Medical Acupuncture and Related Techniques) congress as well as DAGfA (German Medical Society of Acupuncture) lecturers and students were asked to locate and mark the APs LI 10 and TH 5 on a research assistant's arm. Identified points were transferred into a coordinate system, and the respective bivariate distribution function was calculated. Additionally, participants filled out a questionnaire about their acupuncture education and experience, the acupuncture style and point localization techniques used most frequently, and their estimation of the size of an AP. Results: The areas of the ellipses, theoretically containing 95% of AP localizations, varied between 44.49 and 5.18 cm(2). The largest distance between 2 identified points was 8.45 cm for LI 10 and 5.3 cm for TH 5. Apart from being trained at the same school, no other factor could be identified that determined the variability in AP localization. Conclusion: Our results indicate that congruity of AP localization among experienced acupuncturists might be low. Although there are some limitations to our results, this possible bias should be taken into account when conducting acupuncture trials and interpreting results of previous acupuncture studies

    Long gravitational-wave transients and associated detection strategies for a network of terrestrial interferometers

    No full text
    Searches for gravitational waves (GWs) traditionally focus on persistent sources (e.g., pulsars or the stochastic background) or on transients sources (e.g., compact binary inspirals or core-collapse supernovae), which last for timescales of milliseconds to seconds. We explore the possibility of long GW transients with unknown waveforms lasting from many seconds to weeks. We propose a novel analysis technique to bridge the gap between short O(s) burst analyses and persistent stochastic analyses. Our technique utilizes frequency-time maps of GW strain cross-power between two spatially separated terrestrial GW detectors. The application of our cross-power statistic to searches for GW transients is framed as a pattern recognition problem, and we discuss several pattern-recognition techniques. We demonstrate these techniques by recovering simulated GW signals in simulated detector noise. We also recover environmental noise artifacts, thereby demonstrating a novel technique for the identification of such artifacts in GW interferometers. We compare the efficiency of this framework to other techniques such as matched filtering

    Parameter estimation for compact binary coalescence signals with the first generation gravitational-wave detector network

    No full text
    Compact binary systems with neutron stars or black holes are one of the most promising sources for ground-based gravitational-wave detectors. Gravitational radiation encodes rich information about source physics; thus parameter estimation and model selection are crucial analysis steps for any detection candidate events. Detailed models of the anticipated waveforms enable inference on several parameters, such as component masses, spins, sky location and distance, that are essential for new astrophysical studies of these sources. However, accurate measurements of these parameters and discrimination of models describing the underlying physics are complicated by artifacts in the data, uncertainties in the waveform models and in the calibration of the detectors. Here we report such measurements on a selection of simulated signals added either in hardware or software to the data collected by the two LIGO instruments and the Virgo detector during their most recent joint science run, including a "blind injection" where the signal was not initially revealed to the collaboration. We exemplify the ability to extract information about the source physics on signals that cover the neutron-star and black-hole binary parameter space over the component mass range 1 M⊙-25 M⊙ and the full range of spin parameters. The cases reported in this study provide a snapshot of the status of parameter estimation in preparation for the operation of advanced detectors. © 2013 American Physical Society.J. Aasi ... J.
