Numerous prospective and retrospective studies have demonstrated the efficacy safety of stereotactic body radiation therapy (SBRT) for prostate cancer. Since SBRT utilizes a very tight margin, management intrafraction motion is necessary. As real-time tracking correction system (Synchrony; Accuray, Sunnyvale, CA) has been introduced in newer platform tomotherapy (Radixact; Accuray), Radixact ca...

While spatial synchrony of oscillating populations has been observed in many ecological systems, the causes of this phenomenon are still not well understood. The most common explanations have been the Moran effect (synchronous external stochastic influences) and the effect of dispersal among populations. Since ecological systems are typically subject to large spatially varying perturbations whi...

Habitat loss is a significant driver of biodiversity loss, causing fragmentation into small, isolated patches suitable land cover. This reduces the permeability landscapes to movement individuals and likelihood metapopulation persistence. Quantifying functional connectivity, ability focal species move between resource patches, therefore essential for conservation management. There substantial e...

Since M. K. McClintock (1971) published the 1st study on menstrual synchrony among women, a number of other studies have also reported synchrony using a variety of methods. The most recent reports of synchrony come from A. Weller, L. Weller, and colleagues, and their findings of synchrony have been getting stronger (by their own account). In this article, the author analyzes their new methodolo...

OBJECTIVE (1) To investigate the neural synchrony hypothesis by examining if there was more synchrony for upright than inverted Mooney faces, replicating a previous study; (2) to investigate whether inverted stimuli evoke neural synchrony by comparing them to a new scrambled control condition, less likely to produce face perception. METHODS Multichannel EEG was recorded via nose reference whi...

UNLABELLED Maintaining behaviorally relevant information in spatial working memory (SWM) requires functional synchrony between the dorsal hippocampus and medial prefrontal cortex (mPFC). However, the mechanism that regulates synchrony between these structures remains unknown. Here, we used a unique dual-task approach to compare hippocampal-prefrontal synchrony while rats switched between an SWM...

Rainer Guski Dept. of Psychology, Ruhr-University Bochum, Germany [email protected] Abstract The systematic analysis of the perception of audiovisual synchrony has shown that auditory delays are tolerated to a certain extent in synchrony judgments, but the variation of spatial separation between light and sound has brought conflicting results: While Lewald & Guski (2003) did not find a...

BACKGROUND Family environment plays an important role in the intergenerational transmission of major depressive disorder (MDD), but less is known about how day-to-day mother-child interactions may be disrupted in families with a history of MDD. Disruptions in mother-child synchrony, the dynamic and convergent exchange of physiological and behavioral cues during interactions, may be one importan...

When populations are synchronized, they rise and fall together. Analysis of population synchrony and its relationship to distance has played a major role in population ecology but has been absent from most studies of managed populations, such as agricultural arthropods. The extent to which populations at different locations are synchronized reflects the relative roles of shared environmental im...

Thalamic firing synchrony is thought to ensure selective transmission of relevant sensory information to the recipient cortical neurons by rendering them more responsive to temporally correlated input spikes. However, direct evidence for a synchrony code in the thalamus is limited. Here, we directly measure thalamic firing synchrony and its stimulus-induced modulation over time, using simultane...
