Inhibition of aerobic metabolism leads to a major disruption of cardiac cell homeostasis. The purpose of the present study was twofold: 1) We determined the relative importance ofjunctional and nonjunctional membrane resistance (Rj and Rm, respectively) in the development of propagation failure during inhibition of aerobic metabolism in guinea pig ventricular cell pairs. 2) We used the patch-ac...

embryonic stem cells are capable of differentiating to variety of cell tissues including cardiomyocytes. this developmental change is accompanied with a great deal of ion channel expression and functions. mouse stem cell derived cardiomyocytes were prepared and separated to yield isolated single cell suspension for cell current recording. in the present study some properties of the k + -current...

[1] Fault processes involve complex patterns of seismic events and aseismic slip. This work develops a three-dimensional (3-D) methodology for simulating long-term history of spontaneous seismic and aseismic slip on a vertical planar strike-slip fault subjected to slow tectonic loading. Our approach reproduces all stages of earthquake cycles, from accelerating slip before dynamic instability, t...

Image completion is one of the subjects in image and video processing which deals with restoration of and filling in damaged regions of images using correct regions. Exemplar-based image completion methods give more pleasant results than pixel-based approaches. In this paper, a new algorithm is proposed to find the most suitable patch in order to fill in the damaged parts. This patch selection ...

Introduction Travelling wave (TW) MRI is a relatively new imaging technique. An antenna is used to generate a TW which then propagates through the bore. This excites all the spins in the subject, allowing large volumes to be imaged simultaneously and reducing B1 field inhomogeneities. So far, most TW studies have used a patch antenna to create the TW, as they are simple in design and can be con...

in this paper, simulation and analysis of thin steel cylindrical shells with elliptical cutouts under oblique loading were studied using finite element method. first, the numerical results were validated by the results of experimental test performed by an instron 8802 servo hydraulic machine. also, the effect of cutout angle (θ), cutout size, cutout position (l0/l) and cutout aspect ratios (b/a...

Introduction: Travelling wave MR imaging exploits the waveguide action of the RF shield. The transmitting and receiving patch antenna is placed at the beginning of the bore of the scanner. Different sections of the bore will have different wave impedances due to different loading conditions. This can lead to abrupt changes in impedance causing large reflections and inefficient power transfer to...

State-of-the-art tissue engineered heart valves are not strong enough to withstand aortic blood pressure levels. When a strong and slowly degrading scaffold is used, the starting position of valvular tissue engineering is a stronger valve and seeded cells are allowed more time to create a strong extracellular matrix. A polycaprolactone knitted patch with leaflets was developed as a valvular sca...

The new services of mobile broadband system can deal with the growth of mobile internet traffic and high data rate. Long Term Evolution (LTE) is one of the prospective solutions to future mobile broadband systems. In this paper, a novel antenna is presented with Split Ring Resonator (SRR) loading suitable for LTE in handheld devices. The radiating element is Planar Inverted FAntenna (PIFA) cons...
