Matrix Ernst Potentials and Orthogonal Symmetry for Heterotic String in Three Dimensions
A new matrix representation for low-energy limit of heterotic string theory reduced to three dimensions is considered. The pair of matrix Ernst Potentials uniquely connected with the coset matrix is derived.

Deforming tachyon kinks and tachyon potentials
In this paper we investigate deformation of tachyon potentials and tachyon kink solutions. We consider the deformation of a DBI type action with gauge and tachyon fields living on D1-brane and D3-brane world-volume.

Inflation and quintessence with nonminimal coupling [PDF]
The nonminimal coupling (NMC) of the scalar field to the Ricci curvature is unavoidable in many cosmological scenarios. Inflation and quintessence models based on nonminimally coupled scalar fields are studied, with particular attention to the balance ...

The Characteristics of Action Potentials in Primo Vessels and the Effects of Acetylcholine Injection to the Action Potentials [PDF]
In a previous study, we found that Primo vessels generate different action potentials in smooth muscles, but this study compared the pulse shape to distinguish the two tissues. Thus, a more sophisticated extracellular experiment was performed in this study using an acetylcholine injection; we then observed changes in the amplitude, FWHM (full width at ...

Knowledge as Potential for Action [PDF]
Can we conceive cogently of all knowledge – in particular, all knowledge of truths – as being knowledge-how? This paper provides reasons for thinking not only that is this possible, but that it is conceptually advantageous and suggestive. Those reasons include adaptations of, and responses to, some classic philosophical arguments and ideas, from ...

Quantum Geometry of Resurgent Perturbative/Nonperturbative Relations
For a wide variety of quantum potentials, including the textbook `instanton' examples of the periodic cosine and symmetric double-well potentials, the perturbative data coming from fluctuations about the vacuum saddle encodes all non-perturbative data in

Contralateral inhibition of click- and chirp-evoked human compound action potentials [PDF]
Cochlear outer hair cells (OHC) receive direct efferent feedback from the caudal auditory brainstem via the medial olivocochlear (MOC) bundle. This circuit provides the neural substrate for the MOC reflex, which inhibits cochlear amplifier gain and is ...

Field theoretical approach to non-local interactions: 1d electrons and fermionic impurities [PDF]
We apply a recently proposed path-integral approach to non-local bosonization to a Thirring-like system modeling non-relativistic massless particles interacting with localized fermionic impurities.

Abnormal Action Potentials Associated with the Shaker Complex Locus of Drosophila [PDF]
Intracellular recordings of action potentials were made from the cervical giant axon in Shaker (Sh) mutants and normal Drosophila. The mutants showed abnormally long delays in repolarization.
