Monoclonal antibodies directed against specific antigens such as CD3, CD4, CD25, CD40, IL-2 receptor, and TNF-a (discussed below) much more selectively influence T-cell subset function. The high specificity of these antibodies improves selectivity and reduces toxicity of the therapy and alters the disease course in several different autoimmune disorders. 

This SQL statement is similar to the previous SQL statement, except that the subset function is used to select only those elements of the coords array for atoms that match the target of interest, here the substructure CSC. The subset function is defined as follows. 

In our previous work [23], we have investigated the use of distributed basis sets for molecular electronic structure calculations that is, basis sets which comprise a number of subsets each subset being centred on a different point in space. In approaching the Hartree-Fock limit, we have found that in addition to the usual atom-centred subsets, functions centred on the bond mid-point are also very useful. For the ground state of the boron fluoride molecule, which we use as a prototype in the present study, such a basis sets may be designated... 

Permissive is a common term used in industry. Permissive typically refers to a subset function of an SIF (e.g., a permissive where a minimum pressure is required to allow the valve to open). It is not typically considered synonymous with SIF. 

It is also possible that the five known major hormone classes can be subdivided. Particularly, the plethora of different gibberellins now known may in the future be grouped into different subsets functioning in the same plant. Furthermore, it is probable that indoleacetic acid, zeatin, abscisic acid and ethylene are not the only active hormones in their classes. 

In addition to the log P, other physico-chemical parameters were investigated as to their relationship with the observed toxicities of both the subgroups and the entire set of 1,4-di-substituted benzene derivatives. Parameters so used include w for each of the subset functional groups (R = NO2, NHj, Cl, OH, NMOj), and the substituents (X) molar refractivity (AMR), cTp, and field and resonance contributions, as listed by Hansch and Leo (1979). While some of the correlation coefficients improved and slightly lower s values were obtained, all these derived equations fail to satisfy the demand for an explanation of all the data with an acceptable standard error of, say, s = 0.3 to 0.4 log units. It can be concluded then, that one or more of the following conditions prevail ... 

As discussed in Section II.A, the adiabatic electronic wave functions and depend on the nuclear coordinates Rx only through the subset... 

Gq is a substructure of Gp (i.e., Gq is isomorphic with a subgraph of Gp) if and only if all the atoms of Gq can be mapped onto a subset of atoms of Gp in such a way that the bonds of Gq map the corresponding bonds which connect the mapped atoms fi om Gp Each mapping between Gq and Gxcan be considered as a function... 

If P is a function of several variables (e.g., when h deseribes more than one partiele in a eomposite system), and if F is a property that depends on a subset of these variables (e.g., when F is a property of one of the partieles in the eomposite system), then the expansion F=Zj ( )j> <( )j F> is viewed as relating only to F s dependenee on the subset of variables related to F. In this ease, the integrals <(l)k F> are earried out over only these variables thus the probabilities Pk = P depend parametrieally on the remaining variables. 

The basic assumption related to the function is that the subset... 

In this subsection we construct a nonnegative measure characterizing the work of interacting forces. The measure is defined on the Borel subsets of I. The space of continuous functions defined on I with compact supports is denoted by Co(I). 

A subset of ion channels not gated by traditional neurotransmitters represents another receptor class. These iaclude potassium, calcium, sodium, and cychc adenosiae monophosphate (cAMP)-gated channels (14—16) for which a large number of synthetic molecules exist that alter ceUular function. 

Since the summation in Eq. (12) may be on any subset of atoms, it can be fine-tuned to best suit the problem at hand. The summation may be over the whole molecule, but it is very common to calculate conformational distances based only on non-hydrogen heavy atoms or, in the case of proteins, even based on only the backbone Ca atoms. Alternatively, in a study related to drug design one may consider, for example, focusing only on atoms that make up the pharmacophore region or that are otherwise known to be functionally important. 

Homeoboxes code for homeodomains, sequences of 60 amino acids that function as the DNA-binding regions of transcription factors. Each homeo-box gene in Drosophila is expressed only in its own characteristic subset of embryonic cells, and almost every embryonic cell contains a unique combination of homeodomain proteins. 

We proceed with cluster series which yield the integral equations. Evidently the correlation functions presented above can be defined by their diagrammatic expansions. In particular, the blocking correlation function is the subset of graphs of h rx2), such that all paths between... 

It is important, however, not to take this analogy too far. In general, the performance of a piece of hardware, such as a valve, will be much more predictable as a function of its operating conditions than will human performance as a function of the PIFs in a situation. This is partly because human performance is dependent on a considerably larger number of parameters than hardware, and only a subset of these will be accessible to an analyst. In some ways the job of the human reliability specialist can be seen as identifying which PIFs are the major determinants of human reliability in the situation of interest, and which can be manipulated in the most cost-effective manner to minimize error. 

Many authors have drawn attention to the resource implications of ab initio calculations. Schlegel and Frisch (1990) give a particularly comprehensive review. The two resources to be considered are CPU usage and disk usage. A small subset of Schlegel and Frisch s tables are given in Table 11.3 n is the number of basis functions and O is the number of occupied orbitals.
