“…Observation of such a line would provide evidence for the existence of supersymmetric dark matter, while non-observation can be used to put constraints on models of the galactic dark matter. A number of new experiments with reasonable energy resolutions are being planned [4] which would be sensitive to photon production in the galactic halo.…”

We compute the annihilation cross-section of two neutralinos at rest into two photons, which is of importance for the indirect detection of neutralino dark matter in the galactic halo through a quasi-monochromatic gamma-ray line. We include all diagrams to one-loop level in the minimal supersymmetric extension of the standard model. We use the helicity formalism, the backgroundfield gauge, and an efficient loop-integral reduction method. We confirm the result recently obtained by Bergström and Ullio in a different gauge, which disagrees with other published calculations.

“…In conditions of insufficient data (incomplete prior knowledge) about the prior distribution or great uncertainty in the generic data sources, we may use "constrained non-informative priors" described by Atwood [17]. This representation of the prior preserves the mean value of the failure rate estimate and maintains a broad uncertainty range to accommodate the sitespecific event data.…”

“…(4) (the mean) are the primary tools for the Bayesian update in this study. Based on Atwood's [17] priors, for Poisson data, the constrained non-informative prior is a gamma distribution with the shape factor and scale factor of the following values:…”

“…Additionally to the segmental electrophysiological reply, the muscles most likely require 20-30 ms longer to create the mechanical answer. 21 This is based on current knowledge of reflex measurements in relaxed muscles. An electromechanical delay between EMG and MMG of ~11.1 ± 0.5 ms and a delay between MMG and force response of ~13.0 ± 1.3 ms have been reported.…”

The present study focuses on an innovative approach in measuring the mechanical oscillations of pre-loaded Achilles tendon by using Mechanotendography (MTG) during application of a short yet powerful mechanical pressure impact. This was applied on the forefoot from the plantar side in direction of dorsiflexion, while the subject stood on the ball of the forefoot on one leg. Participants with Achilles tendinopathy (AT; n = 10) were compared to healthy controls (Con; n = 10). Five trials were performed on each side of the body. For evaluation, two intervals after the impulse began (0-100ms; 30-100ms) were cut from the MTG and pressure raw signals. The intrapersonal variability between the five trials in both intervals were evaluated using the arithmetic mean and coefficient of variation of the mean correlation (Spearman rank correlation) and the normalized averaged mean distances, respectively. The AT-group showed a significantly reduced variability in MTG compared to the Con-group (from p = 0.006 to p = 0.028 for different parameters). The 95% confidence intervals (CI) of MTG results were disjoint, whereas the 95% CIs of the pressure signals were similar (p = 0.192 to p = 0.601). We suggest from this work that the variability of mechanical tendon oscillations could be an indicative parameter of an altered Achilles tendon functionality.
