Sentences with phrase «between magnetic activity»

To test for a correlation between magnetic activity and photometric variability, we searched for H$ \ alpha $ emission among eight L3 $ - $ T2 ultra-cool dwarfs with extensive previous photometric monitoring, some of which are known to be variable at 3.6 $ \ mu $ m or 4.5 $ \ mu $ m.

In addition, I will also present the first results of my postdoctoral stay at the University of Western Ontario: a search for H - alpha emission in ultra-cool dwarfs to seek a correlation between magnetic activity and photometric variability.

In 2015, NASA launched the Magnetospheric Multiscale spacecraft to study the mysterious interactions between Earth and the solar wind when our planet's magnetic field lines occasionally break and reconnect, which also affects auroral activity.

He used functional magnetic resonance imaging (fMRI), a means of measuring brain activity by detecting blood flow changes inside the brain, to measure differences in the strengths of communications between brain regions.

Using functional magnetic resonance imaging — a technique that monitors brain activity in real time — the Johns Hopkins group found reversing a decision requires ultrafast communication between two specific zones within the prefrontal cortex and another nearby structure called the frontal eye field, an area involved in controlling eye movements and visual awareness.

Still, he argues, differences in cluster N activity between migratory and nonmigratory birds indicate it does have a role in navigation, and the new data fit predictions of the visual magnetic perception theory.

Neuroscientist Jason Cooperrider and colleagues scanned Grandin's brain using three different methods: high - resolution magnetic resonance imaging (MRI), which captures the structure of the brain; diffusion tensor imaging (DTI), a method to trace the connections between brain regions; and functional MRI, which indicates brain activity.

Spence and colleagues use functional Magnetic Resonance Imaging (fMRI) technology to determine whether someone is fibbing by tracing blood flow to certain areas of the brain, which indicates changes in neuronal activity at the synapses (gaps between the neurons).

This period covers three of the Sun's 11 - year activity cycles, which see fluctuations in the rate at which energetic particles are created by the interaction between the Sun's magnetic field and its hot, highly charged outer layers.

Your own 300 year long sunspot data (as well as those of Wang, Lean, and Sheeley) http://www.vukcevic.talktalk.net/TMC.htm also suggest that there is an (for some inconvenient) direct strong link between solar activity and the Earth's magnetic field change.

Recent experimental work at CERN supports an hypothesis that solar magnetic activity throttles formation of cloud water droplet condensation sites and this then explains the correlation between solar magnetic minima with cold epochs.

However, my impression is the emperical evidence for the relationship between solar magnetic activity and atmospheric temperature is a correlation between their short term fluctuations.

The correlation between sunspots and magnetic activity on the sun is less than one, and has been going down in the last few decades.
