Asynchronous condition

When synthesizing an asynchronous preset clear flip-flop, the recommendation is to assign only constant values under the asynchronous conditions. If a variable is asynchronously read, there is a potential for a functional mismatch to occur. Here is an example. 

Recommendation Avoid asynchronously reading a variable and assigning it to a flip-flop else ensure that there are no changes on asynchronous data when the asynchronous conditions are active. 

Equation 1.7). A concerted synchronous transition state [15] (the formation of new bonds occurs simultaneously) and a concerted asynchronous transition state [16] (the formation of one reaction depends on the nature of the reagents and the experimental conditions [17]. 

Multiple motor unit summation involves recruitment of motor units. As the number of motor units stimulated at any given moment increases, the strength of contraction increases. Asynchronous motor unit summation refers to the condition in which motor unit activation within a muscle is alternated. In other words, at one moment, some of the motor units within the muscle are activated, while other motor units are relaxed. This is followed by the relaxation of previously activated motor units and activation of previously relaxed motor units. Consequently, only a fraction of the motor units within the muscle generate tension at any given moment. Therefore, this type of summation may generate submaximal contractions only. 

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]. 

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. 

The versatile drive system of the asynchronous canned motor has set fresh yardsticks for centrifugal pumps operating under high-pressure conditions. The operating limits for pressure, temperature and toxicity of the flow product have been extended by some orders of magnitude. This is the logical result of the response to heightened safety environment requirements, and means that technical processes can now be implemented for the manufacture of new products. 

For nonlinear motors operating at far from equilibrium, velocity reversal allows direction reversal without a change in the microscopic mechanism. Molecular motors are classified in two groups depending on whether they operate in groups or individually. Those that operate in groups are relevant to muscle contraction. In principle, muscle fibers can oscillate in appropriate conditions. Skeletal muscle myofibrils can oscillate spontaneously for example, spontaneous oscillations of asynchronous muscles are common in the wings of many insects. 

In the case of an asynchronous service call, for example, the specifications of both caller and callee have to be completed for event handling. Concerning the callee, the export interface has to contain the signatures of the thrown events and the body deflnition has to include further specifications regarding under which conditions an event is raised. Analogously, for the import interface of the caller it has to be specified in which events it is interested in. In the body it has to be defined how the caller reacts when a certain imported event is raised. ... 

Pacman 26 is also capable of catalytic olefin oxidation using O2 as the terminal oxidant and oxygen atom source. The photoreaction is efficient and clean, as photocatalysis can be carried out with turnover numbers exceeding 1000 for styrene oxidation (181). More recently, it has been found that hydrocarbons can also be oxidized under similar photooxidation conditions (183). Product appearance quantum yields ( p) are listed in Table XII for the photoreactions of 26 with hydrocarbon substrates. The correlation between hydrocarbon IE and log( ox) was taken as evidence of a mechanism in which H abstraction occurs via an asynchronous PCET to the ferryl operates for this system (71,184). As shown in Fig. 27, the corresponding relation employing the... 

Since condition (9.22) is valid for a circular orbit in the drift velocity field as well, the radii of stable attracting trajectories and the basins of attraction can be determined from Eqs. (9.51) and (9.22). As a result, the radius of the resonant attractor becomes a nonlinear function of the time delay t in the feedback loop, as shown in Fig. 9.12(b). As under one-point feedback (compare Fig. 9.3), the theoretical predictions are violated for a small attractor radius R < ta 0.2A. In this case the amplitude of the first Fourier component of the feedback signal practically vanishes, and entrainment or asynchronous attractors are observed instead of the resonance attractor [47]. 

MW effects can therefore act as a useful tool enabling appreciation of the asynchronicity of TS. This is especially true of 1,3-dipolar cycloadditions (cf. Chapter 11) [76]. Because these reactions are well-known to proceed via asynchronous mechanisms, MW-specific effects are expected, and were often apparent when MW and A were seriously checked under similar sets of conditions [77, 78]. A specific case is illustrated here (Fig. 4.10) [79]. 

The asynchronous way of a-oxide splitting is observed only when the arising cation centre is stabilized by a- or -participation The direction of the skeletal shift in such systems is determined only by the configuration of the breaking bond and does not depend on the structure of the syn-located bridge this factor, however, exerts an essential influence on the composition of the reaction products which also depends on the nature of the acid and on the reaction conditions. In all these rearrangements no products of homo-allylic conjugation with the double C —C bond are formed.
