Epipolar rectification of a stereo pair is the process resampling images so that apparent motion corresponding points horizontal. This an important preliminary step in depth estimation, substituting by disparity estimation. Most methods rely on perspective transform both images, which has advantage to simulate different attitude pinhole cameras. A limitation when epipole inside image domain, it...

Delayed rectification was elicited in frog's skeletal muscles bathed in choline-Ringer's solution, in normal Ringer's solution with tetrodotoxin, in 40 mM Na(2)SO(4) solution with tetrodotoxin, and even in 40 mM K(2)SO(4) solution when the membrane had been previously hyperpolarized. However, after a sustained depolarization current-voltage relations in 40 mM K(2)SO(4) and in 40 mM Na(2)SO(4) s...

TASK-2 is a member of the two-pore domain K(+) (K(2P)) channel family that is expressed at high levels in several epithelia, including the proximal tubule. In common with the other TASK channels, TASK-2 is sensitive to changes in extracellular pH. We have expressed human TASK-2 in Chinese hamster ovary cells and studied whole cell and single-channel activity by patch clamp. The open probability...

3D reconstruction of indoor scenes is a hot research topic in computer vision. Reconstructing fast, low-cost, and accurate dense 3D maps of indoor scenes have applications in indoor robot positioning, navigation, and semantic mapping. In other studies, the Microsoft Kinect for Windows v2 (Kinect v2) is utilized to complete this task, however, the accuracy and precision of depth information and ...

By means of fluctuational electrodynamics, we calculate radiative heat flux between two planar materials respectively made of SiC and SiO2. More specifically, we focus on a first (direct) situation where one of the two materials (for example SiC) is at ambient temperature whereas the second material is at a higher one, then we study a second (reverse) situation where the material temperatures a...

Many of the nonlinear membrane properties displayed by neostriatal spiny projection neurons are conferred by their voltage-gated potassium (K+) currents, including an inwardly rectifying current (IKir), fast (IAt), and slowly (IAs)-inactivating A-currents, and a slow, noninactivating current. The relative contribution of these K+ currents to the pronounced inward and outward rectification of th...

1. The ATP receptor subunit P2X2 was expressed in Xenopus oocytes and human embryonic kidney (HEK) 293 cells. ATP-activated currents were studied with two-electrode voltage clamp recordings from oocytes, whole-cell recordings from HEK 293 cells, and outside-out patch clamp recordings from both cell types. The steady-state current-voltage (I-V) relation showed profound inward rectification in al...

There has been an increasing interest in the 3D imaging in the fields of entertainment, simulation, medicine, 3D visual communication, 3D tele-robotics, and 3D TV to augment the reality of presence or to provide vivid and accurate structure information. In order to provide vivid information in these and other 3D applications, efficient techniques to generate, store, and view the stereoscopic vi...
