Underlying components

The important underlying components of protein motion during a simulation can be extracted by a Principal Component Analysis (PGA). It stands for a diagonalization of the variance-covariance matrix R of the mass-weighted internal displacements during a molecular dynamics simulation. [Pg.73]

You have now defined your business needs and gained an idea of the group of employees that requires attention, in order to address these. Equipped with this, you can move on to determining whether business needs can be translated into specific human resource requirements. This means attempting to translate them into competencies, their underlying components (knowledge, skills and attitudes), and experience. The following questions will help you to translate business needs into HR needs ... [Pg.200]

Modulations are normally described as waves. The modulation wave can fit exactly with the underlying unmodulated component, or more precisely with the unit cell of the underlying component, in which case the structure is described as a commensurately modulated structure. In cases where the dimensions of the modulation are incommensurate (i.e., do not fit) with the unit cell of the underlying structure, the phase is an incommensurately modulated phase. Modulation changes are normally continuous and reversible. [Pg.193]

That said, we sometimes refer to a high-level partitioning structure as architecture, either technical architecture (having to do with underlying component technology, inde-... [Pg.432]

When the creation of long-term memories— repeated stimulations interrupted by rest periods—was simulated in this preparation by repeated pulses of serotonin, anatomical changes occurred. Specifically, new synaptic connections were created. It is likely that there are two underlying components to formation of new synaptic connections. One is local protein synthesis in the nerve terminal and the other is CREB (cAMP response element binding) dependent transcription in the neuronal nucleus. Of course, serotoiun pulses also stimulated the release of glutamate. So now the question is how repeated pulses of serotonin are related to protein synthesis and formation of new synapses. [Pg.313]

In Set I, cross-validation found 6 underlying components. Instead of the true 9, because of the high correlation among certain profiles and one source contribution being below the noise level. [Pg.277]

The shape of fused peaks normally differs from that of the underlying component peaks. Large shape differences are apparent to the eye examples can be seen in the third and fourth peaks from the left-hand side in any of the rows of peaks of Figure 5.8. For these fused peaks the resolution is 0.5 and 0.75, respectively. Small shape differences, such as those found for the second peak (Rs = 0.25) from the left of Figure 5.8, may not be visually apparent, but their altered mathematical form can be detected as a difference in statistical moments [42]. [Pg.136]

The concept of transferability and a detailed understanding of these amide modes provides the basis for quantitative estimation of secondary structure for unknown proteins and polypeptides. The quantitative methods currently used to analyze vibrational spectra of proteins can be classified into two categories (1) methods based on decomposition of band contours into underlying components characterized by distinct frequencies, and (2) methods based on principles of pattern recognition. [Pg.239]

Toxicity tests conducted on individual components of whole mixtures also provide useful information to risk assessors. These tests may be conducted in isolation, in combination with other components of the mixture, or as an element of a defined-mixture study. Individual component approaches can be used to examine the assumptions underlying component-based risk assessment methods described in the next section. Toxicity tests on individual components are less expensive and faster than whole mixture and defined mixture approaches but lack information on interactions and unknown components. [Pg.1705]

The model is not fully identified. Unidentified models appear when the k-rank conditions (p.lll) are not satisfied. Consider for example a second-order calibration problem in which two samples are modeled using PARAFAC. One sample may be an unknown sample with, say, R underlying components and the other sample a pure standard with only one underlying component. It follows that the true sample-mode loading ideally holding the estimated relative concentrations has the form... [Pg.117]

The General Structure of Multiple-Source Plume Models Multiple-source plume (and particularly Gaussian plume) models (Calder 1977) are commonly used for predicting concentrations of inert pollutants over urban areas. Although there are many special-puipose computational algorithms currently in use, the basic element that is common to most is the single-point-source release. The spatial concentration distribution from such a source is the underlying component and the multiple-source model is then developed by simple superposition of the individual plumes from each of the sources. [Pg.876]

The two components have now been selected (Fig. 3.19). It is often desirable to change the name of a component. For example, suppose we want to use C3 for propane and IC4 for isobutane. This can be accomplished by highhghting the name listed under Component ID and typing the desired name. Chck anyplace on the window, and the message shown in Figure 3.20 will appear. Chck Rename. Repeat for isobutane. [Pg.48]

The low surface tension of HFEs helps these fluids to easily penetrate tight spaces, especially between and under components of populated printed circuit boards. In addition, this is supported by the low viscosity of the HFEs that also allow it to quickly drain from the parts that have been cleaned. [Pg.916]

Derivatives Derivatives are frequently used to enhance resolution. The principle is that pure peaks are generally unimodal, so contain only one maximum. Peak clusters arising from several underlying components, if not completely resolved, contain inflexion points. Derivatives resolve these out, as illustrated in Figure 3. These also allow peak maxima and widths to be measured more easily. For example, the center of a peak has a first derivative of 0, so crosses the baseline in the derivative spectrum. It is often easier to measure a peak crossing the baseline than estimate the exact center of a flat peak. In some forms of spectroscopy such as electron spin resonance, spectra are conventionally recorded directly in the derivative mode, which allows good resolution of hyperfine... [Pg.619]
