Contraction of the cardiac muscle of the heart is initiated and controlled by an electrical stimulus called the cardiac action potential. It is a small (∼0.1 V) and transient (0.15–3.0 s) change of voltage across the cell membrane. This change in voltage results from the passage ...
called the pacemaker cells, which are located in the border zone between thesinus venosusand theatrium. Because all cardiac muscle cells are electrically connected, this action potential can rapidly spread over the entire heart, triggering a coordinated, forward-moving wave ofcardiac muscle contractio...
For recording of flytrap APs in our heat-stimulation investigations, we used surface electrodes measuring the extracellular potential of a trap. The measuring electrode (blank silver wire; 0.25 mm, WPI, Sarasota, USA) was inserted into the trap, with the electrical connection enhanced by application...
The world is waking up to a crisis of ocean plastic—and we're tracking the developments and solutions as they happen.
The heart has a complex geometry. When a general difference scheme is used to solve the heart potential propagation, finite difference discretization of higher-order derivatives at irregular boundaries can be very complicated and challenging. To address this, we propose a ghost-structure (GS) method...
could be in the shape of a heart or any other image a designer creates. On top of the button is a short, direct command. “Buy now” is popular, but again, creative writers can come up with all kinds of phrases. Potential customers click on the button and will be led to another ...
Collectively, these findings suggest that both the personality of the cat and genetic variation in the genes encoding olfactory receptors may play a role in how cats respond to cat-attracting plants. Furthermore, the data suggest a potential distinct mechanism of action for actinidine. ...
Moreover, empowerment can encompass a change in how participants engage with their surroundings, that is to say their access to and use of resources and the formation and potential of social relations and networks. This concept has previously been used to investigate change in empowerment in vulner...
as the intensity of the SPEECH program differed compared to those of the AVG and SNAVG groups, a greater effect of spontaneous development may be possible in the former group. Future studies are needed in order to assess the potential effects of different remediation programs’ intensities upon ...
Spontaneous desorption can be initiated by switching off the accelerating potential of the gauge had under study after reaching either a selected total gas pressure (Baker and Giorgi, 1960) or any other pressure (Cobic et al., 1961b). In the first case it was observed that the total amount...
