Comparative Study of full QCD Hadron Spectrum and Static Quark Potential with Improved Actions [PDF]
Phys.Rev.D60:114508,1999, 1999 We investigate effects of action improvement on the light hadron spectrum and the static quark potential in two-flavor QCD for $a^{-1} \approx 1$ GeV and $m_{PS}/m_V = 0.7-0.9$. We compare a renormalization group improved action with the plaquette action for gluons, and the SW-clover action with the Wilson action for quarks.

Warm Body Temperature Facilitates Energy Efficient Cortical Action Potentials
PLoS Comput. Biol., 2012 The energy efficiency of neural signal transmission is important not only as a limiting factor in brain architecture, but it also influences the interpretation of functional brain imaging signals.

In action with action potentials
Journal of Physics: Conference Series, 2019 Abstract The subject of bioelectricity is for many life science students the first encounter with biophysics. The transfer of knowledge on electricity from the context of physics to the context of physiology is not without difficulty.

Perfect actions with chemical potential [PDF]
Physics Letters B, 1998 We show how to include a chemical potential in perfect lattice actions. It turns out that the standard procedure of multiplying the quark fields , \bar at Euclidean time t by \exp(\pm t), respectively, is perfect. As an example, the case of free fermions with chemical potential is worked out explicitly.

The Relationship between Nerve Conduction Study and Clinical Grading of Carpal Tunnel Syndrome [PDF]
Journal of Clinical and Diagnostic Research, 2016 Introduction: Carpal Tunnel Syndrome (CTS) is the most common nerve entrapment. Subjective sensory symptoms are common place in patients with CTS, but sometimes they are not supported by objective findings in the neurological examination ...

Correlation of action potentials in adjacent neurons
, 2015 A possible mechanism for the synchronization of action potential propagation along a bundle of neurons (ephaptic coupling) is considered. It is shown that this mechanism is similar to the salutatory conduction of the action potential between the nodes of

Temporal Precision of Spike Trains in Extrastriate Cortex of the Behaving Macaque Monkey [PDF]
, 1996 How reliably do action potentials in cortical neurons encode information about a visual stimulus? Most physiological studies do not weigh the occurrences of particular action potentials as significant but treat them only as reflections of average ...

Optical recording of action potentials in mammalian neurons using a microbial rhodopsin
Nature Methods, 2011 Reliable optical detection of single action potentials in mammalian neurons has been one of the longest-standing challenges in neuroscience. Here we achieved this goal by using the endogenous fluorescence of a microbial rhodopsin protein, Archaerhodopsin

Topological Regulation of Synaptic AMPA Receptor Expression by the RNA-Binding Protein CPEB3
Cell Reports, 2016 Synaptic receptors gate the neuronal response to incoming signals, but they are not homogeneously distributed on dendrites. A spatially defined receptor distribution can preferentially amplify certain synaptic inputs, resize receptive fields of neurons ...

General Solutions for Tunneling of Scalar Fields with Quartic Potentials
, 1993 For the theory of a single scalar field $\varphi$ with a quartic potential $V(\varphi)$, we find semi-analytic expressions for the Euclidean action in both four and three dimensions.
