Intrinsic mode

The energy distribution spectra collected by DB can be resolved into a sum of Gaussians, each representative of a positron state [3], with intensities, iP, and full widths at half maximum (fwhm), Tj. The subscripts are the same as for PALS. The DB intensities can be quantitatively correlated to those from PALS. Because p-Ps annihilates in an intrinsic mode, one has T T3 < r2. The DB results are conveniently presented in the form of the global fwhm of the energy distribution spectra. Similar treatments can be made, with a better resolution, in angular correlation (AC) experiments. 

Further support to the model should be found by examining the values of F], as deduced from AC or DB measurements since p-Ps annihilates in an intrinsic mode, this parameter should reflect directly the average Ps kinetic momentum. However, the data on F, are usually poorly defined [61, 64], so that the correlation with y is more conveniently sought using experimental values of r3, provided that the momentum distribution of the valence electrons participating in the o-Ps pick-off annihilation is reasonably solvent independent. Such a correlation has been effectively found for a variety of solvents at various temperatures [61], leading to ...

On the other hand, for its good adaptive decomposition effect, the empirical mode decomposition (EMD) method proposed by Huang et al in 1998 provides a possible approach to solve this problem (Huang et al. 1998). Based on the EMD method, it can make directly decomposed to the observed gas emission data, the approximately orthogonal intrinsic mode function (IMF) can be obtained, whole emission observations is the sum of these IMF components. 

The intrinsic mode extraction of gas emission monitoring value can be achieve through the EMD method, although the EMD method has not been strictly theoretical proved, however, it has... 

According to Huang et al, intrinsic mode components should meet the following two conditions (Huang et al. 1998) ... 

By using the gas emission historical data, obtains its intrinsic mode functions (namely IMF component) through the EMD decomposition, then corresponding respectively to each intrinsic mode make forecast by using the function fitting method of ANN, on this basis, different intrinsic mode prediction results can be synthesized and reconstructed, thus obtaining the theoretical prediction results for gas emission. 

Crystals of quartz (silicon dioxide) and sapphire (aluminum oxide), to name two very good insulators, have large band gaps (both around 8 electron volts, or "ev"), so they do not conduct electricity at room temperature, for the same reason that pure silicon does not. However, if they are heated to about 750°C (red hot), a few electrons from the valence band will randomly have the energy required to put them up in the conduction band, and the materials will become slightly conductive. In the figure, this is represented by the "intrinsic" arrow. Silicon, with an energy gap of about 1 ev, only needs to be heated to about 200°C in order to conduct via the intrinsic mode. 

The origin of the other two modes for these polymers appears to be associated with the intrinsic modes of the neutral polymers with one of the following possibilities (1) these modes are raised very closely to the intrinsic modes (2) they are identical to the intrinsic modes. In other words, such modes would be both IR and Raman active [40,159]. Considering that partially oxidized P3HT shows the doping-associated IR characteristics to be well related to those of P3MT (see Section 2.1), these features would be common to 3-alkyl substituted polythiophenes. Introduction of the alkyl substituents does not affect the electronic structure and properties of the polythiophene backbone so much. 

To further understand the intrinsic mode coupling, we investigated the optical pulse response of GI POFs in detail [33]. Figure 3.11a shows the power coupling coefficients for intrinsic mode coupling due to microscopic heterogeneities with... 

Molecular resonators are thought to be molecules whose intrinsic modes can resonate, or transfer twist mode to the protein backbone. The latter phenomenon is an alternative way for an interaction to take place. These so-...

From an ensemble of structures, such as those obtained with NMR or via molecular dynamics, it is possible to determine eigenvectors that describe the path along which the different protein elements may move. Using these eigenvectors, or modes of flexibility, it is possible to transform the solution structure into the crystal structure, indicating that the observed differences are within the confines of the intrinsic flexibility of the protein. This is further corroborated by the fact that when PYP is crystallized in the P65 space group, instead of the P63 space group, these structures are different but are within the confines of the intrinsic modes of flexibility of the protein.
