Asynchronous mode

Aghajanian GK, Marek GJ (1999) Serotonin, via 5-HT2A receptors, increases EPSCs in layer V pyramidal cells of prefrontal cortex by an asynchronous mode of glutamate release. Brain Res 825 161-71... [Pg.324]

For direct transmission, the synchronous data transfer mode is more suitable than the asynchronous mode. If multicast is required or frequent disruptions occur, the asynchronous data transfer mode is preferable. [Pg.404]

Strontium ion was found to support the asynchronous mode of transmitter release in isolated layer V pyramidal cells of the prefrontal cortex (Aghajanian and Marek 1999). This is apparently mediated through calcium-binding protein synaptotagmin III, as strontium does not support the function of calciumbinding synaptotagmins I and II (Li et al. 1995). [Pg.139]

The less commonly used modes faU into several groups. Asynchronous modes (AGO, VOO, DOG) are not frequently used as permanent modes. They may be used as temporary modes to assess capture and prevent sensing of electromagnetic interference (Fig. 3.6). Triggered modes (e.g., VVT and AAT) also... [Pg.77]

Pacing system inhibition from interference is more important in the pacemaker-dependent patient. If inhibition is observed in a pacemaker-dependent patient, electrocautery application should be limited to 1-2 s with a rest period of approximately 10 s. This will allow the pacemaker to function properly for a greater portion of the time. In some cases back-up temporary transvenous or transcutaneous pacing will be required, or the pacemaker can be programmed to the asynchronous mode of function. [Pg.599]

Placing a magnet over the pulse generator makes the pacemaker temporarily revert to an asynchronous mode (safety mode) at a preset rate. [Pg.194]

If the masses are displaced in an arbiPary way or arbiPary initial velocities are given to them, the motion is asynchronous, a complex mixture of synchronous and antisynchronous motion. But the point here is that even this complex motion can be broken down into two normal modes. In this example, the synchronous mode of motion has a lower frequency than the antisynchronous mode. This is generally Pue in systems with many modes of motion, the mode of motion with the highest symmePy has the lowest frequency. [Pg.137]

Using a Terminal. Dial-up terminals may also be used to access a vendor s databases however, the terminal, personal computer, word processor, or microcomputer must all be compatible with specific functionaHties. Eor example in order to access the DIALOG service these must all be TTY compatible have ASCII coding and be compatible for asynchronous transmission in full-duplex mode for communication through DIALNET,... [Pg.457]

Since the first report by lino and co-workers in 1994 (lino Tsukioka 1994), asynchronous wave-like [Ca2+]j oscillations have emerged as an universal mode of Ca2+ signalling in in situ VSMCs (Table 1). Confocal microscopy of intracellular Ca2+-sensitive dyes in intact blood vessels, reveals recurrent intracellular Ca2+ waves travelling through the longitudinal axis of the ribbonshaped VSMCs. These waves, which are usually but not always initiated by agonists, do not propagate between cells. [Pg.28]

As evidenced by Figure 10.15, some asynchronous motion does exist for this sample within the 2990 cm"1 band. The intensity of this behavior is an order of magnitude less than the synchronous motion, as noted by the scales of the maximum contour levels in both plots. This asynchronous data suggests that the two populations of C-H bonds (those on the backbone carbons, and those associated with the methyl groups) do not precisely orient in phase with one another. Since these data were collected at a frequency above the mechanical glass transition, this could be a manifestation of the appearance of glassy modes of re-... [Pg.223]

Let us consider the case of a = 30 corresponding to a weakly developed chaotic attractor in the individual nephron. The coupling strength y = 0.06 and the delay time T2 in the second nephron is considered as a parameter. Three different chaotic states can be identified in Fig. 12.16. For the asynchronous behavior both of the rotation numbers ns and n f differ from 1 and change continuously with T2. In the synchronization region, the rotation numbers are precisely equal to 1. Here, two cases can be distinguished. To the left, the rotation numbers ns and n/ are both equal to unity and both the slow and the fast oscillations are synchronized. To the right (T2 > 14.2 s), while the slow mode of the chaotic oscillations remain locked, the fast mode drifts randomly. In this case the synchronization condition is fulfilled only for one of oscillatory modes, and we speak of partial synchronization. A detailed analysis of the experimental data series reveals precisely the same phenomena [31]. [Pg.340]

Continuous product flows under high-pressure conditions (p > 30 MPa) can only be achieved with hermetic centrifugal pumps. Although the two drive systems that can be used - the permanent magnet coupling and the asynchronous canned motor - have the same mode of operation, they differ in their applications and their safety ranges. [Pg.599]

The first block DIV is a frequency divider. This block has 2 modes of operation, the normal mode and the test mode. In the test mode, the UART chip runs 16 times faster than in the normal mode. Also, the transmission data rate of the UART chip is 16 times faster than the receiving rate. Each block is initialized by setting the reset line low by applying a 0 to port MR. The TX block accepts 8-bit parallel data from the microprocessor interface (MP) block and transmits it serially to the RS-232 port through port DOUT. Conversely, the RX block receives serial data input, and sends it in 8-bit parallel format to the MP block. Again, the transmitter runs at 16 times the speed of the receiver. The microprocessor interface (MP) block asynchronously controls the parallel data flow between the RX / TX blocks and the microprocessor data bus. [Pg.147]
