Temporal processes

Whereas scintillation screens can be used to directly view x-rays passing through the body, the dose to a patient is too high. Instead, scintillation screens are combined with video cameras or electronic intensifier tubes and video cameras. This detection scheme is used in digital radiography where digital x-ray images are recorded, and fluoroscopy where temporal processes are to be followed.

Microarray data cannot be analyzed by purely brute force techniques to generate a causal model of a set of biological processes because the data represents gene expression patterns that are only correlated with temporal processes of interest in the organism. Lander (1999) comments on this problem as follows ... 

This result is very interesting because whilst we have shown that G(0) has been excluded from the relaxation spectrum H at all finite times (Section 4.4.5), it is intrinsically related to the retardation spectrum L through Jc. Thus the retardation spectrum is a convenient description of the temporal processes of a viscoelastic solid. Conversely it has little to say about the viscous processes in a viscoelastic liquid. In the high frequency limit where co->oo the relationship becomes... 

The hippocampus is characterized by a series of glutamatergic neurons, which can create rhythms of electrical activity necessary for the generation of memory traces in the brain. The cerebellum, a region dedicated to the temporal processing of motor and cognitive in-... 

In order to analyze the temporal process of steady-state formation in a course of tunnelling reactions in crystals, Kotomin [85] solved numerically equation (4.3.28) and the relevant equation (4.1.19) for the reaction rate K(t). It is clearly seen in Fig. 4.11 that the steady-states formed after the transient...

Temporal extrapolation is important in terms of the duration of the exposure, the number of exposures, and the nature of the response to these in the organism. Chapter 6 reviews relationships between temporal exposure in relation to acute-to-chronic extrapolation, reversibility, and latency in terms of the interaction between substances and individual organisms. Other temporal extrapolation approaches are needed when considering temporal processes in organisms themselves. These relate to seasonal variability in sensitivity, recovery at the population level, and adaptation to stressors.

Rocks, even in their solidity and massive deadness, were historical forms. The particular qualities that they possessed were an outcome of the mode and time of their formation. Nature could no longer be considered an eternal realm. It is not exempt from the modulating rhythms and decisive episodes that structure and restructure the human world. Hegel s philosophy accentuated temporality, process, development and change. It sidled towards evolutionary theory. 

These results were obtained, using hydrogen absorption into pure aluminum between 300 and 1050 °C and were calculated by temporal process degassing. Eichenauer et al. also reported that the square root Sievert s law is satisfied within the limit of error in the solid and in the liquid state. Utilizing the fact that diffusion in the metal is responsible for the hydrogen degassing rate of the solid aluminum they deduced the diffusion coefficient to be D = 0.11 exp (—9780/ RT) cm s . The heat of solution was calculated from these measurements by Birnbaum et al. [7] and Ichimura et al. [8] and found to be in the range of + 0.6 to + 0.7 eV.

Time Scales and Temporal Processes. One of our recurring themes in the pages to follow will be the role of disparate scales in characterizing processes and structures within materials. In addition to the diversity of spatial scales, there are a host of processes in solids which are themselves characterized by widely different time scales. As a result, we will be forced to adopt a series of different measures of the passage of time. One of the elemental processes in solids that will occupy much of our attention is that of the vibrations of solids. As will become evident in later chapters, atomic vibrations are characterized by frequencies on the order of lO -lO " Hz, which corresponds to a time scale on the order of one-tenth of a picosecond. As a result, we will make use of both 1.0 fs = 10 s and 1.0 ps = 10 s in describing atomic motions.
