Mutually-exclusive condition

To maintain the best possible focusing for an entire concave grating of large aperture, it is therefore necessary to satisfy what at first glance seem to be two mutually exclusive conditions (4.12) ... 

Resource allocation refers to the process of sharing an arithmetic-logic-unit (ALU) under mutually-exclusive conditions. Consider the following if statement. 

Maps operations onto functional units, and minimizes the total execution time of expressions using associativity and commutativity. Shares functional units among mutually exclusive conditional branches, inserting multiplexors as necessary. 

Sharing functional units between mutually exclusive conditional branches. 

This chapter describes algorithms for resource conflict resolution. Resource conflicts occur when multiple operations activate the same hardware resource simultaneously. When all operations in the hardware model have fixed execution delays, conflict resolution becomes part of the scheduling and resource binding tasks. In particular, operations scheduled to different control stq)s or belonging to mutually exclusive conditional branches can share their hardware resources. Consider for example the force-directed scheduling technique [PK89b]. Operations with similar resources are first scheduled to reduce their concurrency, then they are bound to hardware resources subject to this schedule. The binding step ensures that no resource conflicts will arise. This approach is, however, restricted to bounded delay operations.

Clearly, these groupings are not mutually exclusive. The chief distinctions are between homogeneous and heterogeneous reactions and between batch and flow reactions. These distinctions most influence the choice of equipment, operating conditions, and methods of design. 

PREPROCESSOR - Modifies the FTAP punch file output for common cause and dependent analyses (conditional probabilities), removes complemented events, and corrects for mutually exclusive events. 

With Rowland gratings, which must be ruled on the surface, these conditions are mutually exclusive, so that the best focusing can be realized only if the aperture is not too large. 

Figure 3.10 Concentration of labeled compound I bound to an enzyme as a function of the concentration of a second inhibitor J. (A) Response of bound I to concentration of / when I and / bind in a mutually exclusive fashion. Note that here the concentration of the bound I is driven to zero at high concentrations of J. (B) Response of bound I to concentration of J when the two compounds bind in a nonexclusive, antagonistic manner to the target enzyme. Note that at high concentrations of J one does not drive the concentration of bound I to zero. Rather, the concentration of bound I at high concentrations of /reflects the concentration of ternary E I J complex. Condition of simulations I IK, = 1 (closed circles), 3 (open circles), and 5 (closed squares). For panel B, y = 5.

Of the examples considered above, two are of phenotypic diversity in a life-history trait where the life-history trait under consideration is clearly a facultative phenomenon. That is, for developmental route in S. ratti and for arrested development, there are distinct, mutually exclusive developmental routes. Thus, diversity in these traits between different parasite lines is relatively easy to observe, as is the response to selection. Both these traits are, in part, affected by environmental conditions and so are phenotypically plastic. For S. ratti, variation in the sensitivity of this plasticity can also be seen. Although environmental sensitivity of arrested development is as yet uninvestigated, by analogy with S. ratti it is likely to vary. 

The differential diagnosis of panic disorder includes other psychiatric illnesses, medical illnesses, and substances that can cause panic attacks. Also included are medical illnesses that cause symptoms resembling panic attacks. It should be mentioned that these other conditions, which are described below, and panic disorder are not necessarily mutually exclusive. In fact, there is a high rate of comorbidity between panic disorder, other anxiety disorders, and mood disorders. Because panic disorder is frequently accompanied by agoraphobia, the differential diagnosis also includes illnesses that are associated with symptoms resembling the avoidance of the agoraphobic patient. 

What s often overlooked is that snch medical conditions and panic disorder are not mutually exclusive. For example, those with asthma or heart disease become conditioned to monitoring bodily signals very closely. At times, they may misinterpret a physical symptom as an impending attack of asthma or angina. This may result in an escalating spiral of anxiety that leads to a panic attack. Thns, those with true medically verified asthma or heart disease can also snffer from panic disorder as an indirect consequence of their medical condition. 

These types are not mutually exclusive, Type 111 systems for example may have been subjected to Type 1 or Type 11 conditions at an earlier stage of their hydrothermal history. 

It would lie beyond the scope of this treatment to describe the various methods now available for determining radical concentrations. Most of them are difficult to apply to the gas phase and none of them is really useful unless (a) the intensity / is very high, i.e. over 1018 quanta.ml-1.sec-1 and (b) experimental conditions are such that radical lifetimes are at least 10 4 second or more. In a way these two conditions are mutually exclusive. 

With the example of p-nitrophenyl esterase the Arnold group demonstrated that even the thermostability of an enzyme is amenable to directed evolution (Giver, 1998). As a test of thermostability the activity in standard conditions (pH 7.5, 0.25 mM p-nitrophenyl acetate) at 30 °C (AJ was compared with the activity in the standard assay at 30 °C (Ar) but after heating to Tm for 10 min (with subsequent cooling on ice and incubation for 30 min at room temperature). The results are shown in Figure 11.10. This work demonstrates that enhanced activity and enhanced stability need not be mutually exclusive. However, the improvements along one of the two axes sometimes tend to be minor, i.e., by a factor between 3 and 5. 

To successfully use high-resolution molecular spectroscopy to study tunneling, two conditions have to be met suppression of hot bands and removal of inhomogeneous broadening. In the traditional technique of equilibrium sample preparation these conditions are mutually exclusive To decrease the hot band intensity one needs to lower the temperature, which entails the condensation of a sample and, consequently, appearance of inhomogeneous spectral effects which are due to intermolecular interactions in the solid. To some extent, a compromise is achieved in the matrix isolation method, where the intermolecular interactions between the guest and host molecules are minimized by using the noble gas matrix. However, even in this case the asymmetry of the potential is... 

The last transition is forbidden because the demands from the angular momentum coupling and the parity requirement are mutually exclusive the coupling of the orbital angular momenta requires the vector addition L + = 0 with L = 1 and hence also = 1 on the other hand, the parity selection rule requires = even, and both conditions cannot be fulfilled simultaneously. Therefore, only five transitions are expected for the K-LL Auger spectrum in neon, and these can be identified in Fig. 3.3.
