Enzymatic reactions with more reaction partners, for instance bi-bi reactions, may either be modeled using convenience or detailed ternary-complex kinetics with different reaction mechanisms, for instance random, ordered or ping-pong.
This is the case of tacrine and its dimeric derivative bis(7 -tacrine which, for instance, paved the way for the development of a broad collection of very interesting homo- and heterodimeric structures, conceived in light of the emerging multi-target approach for AD-related drug discovery.
A lot of practical applications can be reformulated as bi-level programming problems, for instance [7 9].
For instance, P (Bi | Ik) is determined by the number of co-occurrences of the taxon Bi and the niche variable Ik and, in principle, allows us to find the most important statistical associations between the niche variables and the taxa distributions.
The concept of 'simultaneous turn over' between catalytic functions in multi-functional catalysis is widely accepted (for instance, in bi-functional metal/acid transformation of alkanes), and this aspect of the proposed mechanism is a 'normal' behaviour in steady state.
For instance, ε(Bi |Bk Bm) measures the statistical interaction between the joint presence of taxa Bm and Bk and that of taxon Bi.
For instance, while stilbene (bis)sulfonic acid congener 2 was only 10-fold selective for FSHR over TSHR, analogue 50 with an IC50 value of 0.9 μM in the FSHR-cAMP assay was essentially inactive at 30 μM in the TSHR-cAMP assay.
For instance, to calculate P(Bi, Bk), where Bi represents presence of species i in grid cell xα : If the mesh size is too small then the probability of a co-occurrence of species i and k is very small.
The BI-RADS 0 cases could then be assessed separately from the BI-RADS 4 and 5 cases, for instance along a "quick assessment route" to the hospital radiology departments.
For instance, the same bi-directional procedure as the one used in [20, 21] is used to switch from the LT model coefficients to a reduced set of LSF vectors at the coder, and vice-versa at the decoder.
