Matrix reducible

If the p labels refer to lattice sites j, this matrix reduces to 6(k) in the KKR matrix M(k) and Eq. (15) can be shown to reduce to Eq. (14). The evaluation of is hindered by the free-electron poles in the b matrices. This has formed a barrier for electronic structure calculations of interstitial impurities, but in some cases this problem was bypassed by using an extended lattice in which interstitial atoms occupy a lattice site. For the calculation of Dingle temperatures [1.3] and interstitial electromigration [14] the accuracy was just sufficient. Recently this accuracy problem has been solved [15, 16]. 

Just as a known root of an algebraic equation can be divided out, and the equation reduced to one of lower order, so a known root and the vector belonging to it can be used to reduce the matrix to one of lower order whose roots are the yet unknown roots. In principle this can be continued until the matrix reduces to a scalar, which is the last remaining root. The process is known as deflation. Quite generally, in fact, let P be a matrix of, say, p linearly independent columns such that each column of AP is a linear combination of columns of P itself. In particular, this will be true if the columns of P are characteristic vectors. Then... 

If u is partitioned into the primary space, a, and an orthogonal space of product operators, f, the partitioned form of the propagator matrix reduces to... 

The high photostability of the nanoparticle originates from protection provided by the silica matrix for the embedded fluorophores. Environmental oxygen is a universal quencher for fluorophores in aqueous solution and the network structure of the silica matrix reduces diffusion of environmental oxygen to the fluorophores. Thus, the photostability of embedded fluorophores is greatly improved [3]. 

To improve the adhesion and interaction in the zeolite/polymer interface, the surface of the zeolites can also be sized (or primed ) by coating the zeolite with an ultrathin layer of the matrix polymer or a different polymer. Sizing of the zeolite particles prior to dispersion in the polymer matrix reduced the stress at the...

Oxidizible substrates from glycolysis, fatty acid or protein catabolism enter the mitochondrion in the form of acetyl-CoA, or as other intermediaries of the Krebs cycle, which resides within the mitochondrial matrix. Reducing equivalents in the form of NADH and FADH pass electrons to complex I (NADH-ubiquinone oxidore-ductase) or complex II (succinate dehydrogenase) of the electron transport chain, respectively. Electrons pass from complex I and II to complex III (ubiquinol-cyto-chrome c oxidoreductase) and then to complex IV (cytochrome c oxidase) which accumulates four electrons and then tetravalently reduces O2 to water. Protons are pumped into the inner membrane space at complexes I, II and IV and then diffuse down their concentration gradient through complex V (FoFi-ATPase), where their potential energy is captured in the form of ATP. In this way, ATP formation is coupled to electron transport and the formation of water, a process termed oxidative phosphorylation (OXPHOS). 

Since there are only two SALC-AOs and both are of different symmetry types these SALC-AOs are MOs and the 2x2 Hamiltonian matrix reduces to 2 lxl matrices. 

One additional factor must be covered. While not classically polyurethane-specific in nature, it is nonetheless a useful tool. The use of a filler can produce a marginal effect on tensile strength. Adding particles to a matrix reduces the tensile... 

One of the problems encountered in the entrapment of activated charcoal in a polymer matrix is the blinding-off of the pores of the charcoal, thus inactivating it. Because the pores of the carbon are responsible for its ability to adsorb organics, any pores that are filled or coated with a polymer matrix reduce its effectiveness. Conventional treatments involve blending the carbon into an acrylic latex and then applying the slurry to a reticulated foam. Upon drying, a coalescence encapsulates the carbon. 

We have used here its inner structure (23.5). The values of the totally reduced matrix (reduced submatrix) elements can be found from pertinent quantities for the conventional submatrix elements of operators Tk using the relationships... 

In the case of steady state bifurcations, certain eigenvalues of the linear-approximation matrix reduce to zero. If we consider relaxations towards a steady state, then near the bifurcation point their rates are slower. This holds for the linear approximation in the near neighbourhood of the steady state. Similar considerations are also valid for limit cycles. But is it correct to consider the relaxation of non-linear systems in terms of the linear approximations To be more precise, it is necessary to ask a question as to whether this consideration is sufficient to get to the point. Unfortunately, it is not since local problems (and it is these problems that can be solved in terms of the linear approximations) are more simple than global problems and, in real systems, the trajectories of interest are not always localized in the close neighbourhood of their attractors. 

The 5-matrix is unitary and symmetric, while the T-matrix is symmetric. This particular definition of the T-matrix reduces for scattering by a central potential to the phase-shift factor in the scattering amplitude,... 

Thermo-mechanical analysis (TMA)26 and DMTA292 have been used to study the viscoelastic properties of bread, a composite two-phase system. The moisture dependence of Tg was similar to that of pure amorphous starch and gluten.242,282 293-295 At the moisture content of bread, water exerts its full plasticization effect on the composite polymer matrix, reducing the effective Tg to about -10° to - 12°C,26,292 well below normal shelf life storage temperatures of this product. 

The v errors within the jth experiment arc statistically interdependent with a covariance matrix X. When the errors are independent the matrix reduces to a diagonal matrix. 

Besides electrophoretic migration, analytes in CE move by a process called electroosmosis (or electroendoosmosis). This phenomenon, occurring also in slab gel electrophoresis, produces electroosmotic flow, the electrically driven flow of the liquid within the capillary. However, while in slab gel electrophoresis the gel matrix reduces EOF to an annoyance, in CE this liquid flow can have a significant effect on the separation process. 

It has been well known that weak interfaces between the inorganic fillers and the organic matrix reduce the mechanical strength of bone cement [38,40,44,45]. The interfacial adhesion strength can be enhanced by plasma treatment, which is generally due to the improved wettability and possibly to the chemical bonds between the filler and the resin [46,47]. Especially in acrylic bone cement, chemical bonds may have an important role in improving the mechanical strength by the plasma treatment. 

Force decomposition algorithms based on a block decomposition of the force matrix reduce the memory and communication costs by a factor of /P versus the atom decomposition algorithms. In the LJ benchmark, the force decomposition algorithm continued to speed up, even when hundreds of processors were used. 

The addition of starch to the PVP matrix reduced the degree of collapse. Although a certain degree of collapse occurred upon storage above Tg, the PVP-starch samples were never fluid or semifluid systems as in the PVP... 

It is straightforward to observe that, for A, = 1, the half sum of the elements of the kth order interaction geodesic matrix reduces to the —> Moreau-Broto autocorrelation descriptor of order k (ATSfe) ... 

Ways to increase membrane durability have been examined by various researchers across the country. Maurtiz et al. examined the use of metal-oxide metal particles to increase the properties of the membrane. A titanium isopropoxide (Figure 11.4) addition to Nation membranes generates quasi-network particles this improves membrane modulus and dimensional stability [17], In addition, the titanium matrix reduces fuel crossover and minimizes chemical degradation. Table 11.2 shows the increase in modulus along with stress and strain and stress changes after the addition of the titanium matrix [17], With a 20% load of the titanium matrix, performance criteria remain comparable. Acid functionality remains intact however, water uptake is reduced as volume inside clusters is occupied. Conductivity is reduced due to chain mobility [17],...
