Activating function

Living systems contain thousands of different enzymes As we have seen all are structurally quite complex and no sweeping generalizations can be made to include all aspects of enzymic catalysis The case of carboxypeptidase A illustrates one mode of enzyme action the bringing together of reactants and catalytically active functions at the active site... [Pg.1147]

Many globular proteins are enzymes They accelerate the rates of chemical reactions m biological systems but the kinds of reactions that take place are the fundamental reactions of organic chemistry One way m which enzymes accelerate these reactions is by bringing reactive func tions together m the presence of catalytically active functions of the protein... [Pg.1152]

Section 27 21 Often the catalytically active functions of an enzyme are nothing more than proton donors and proton acceptors In many cases a protein acts m cooperation with a coenzyme, a small molecule having the proper func tionahty to carry out a chemical change not otherwise available to the protein itself... [Pg.1152]

The activation function/(.v) (where. v is the weighted sum) can take many forms, some of which are shown in Figure 10.21. From Figure 10.21 it can be seen that the bias bj in equations (10.54) and (10.55) will move the curve along the. v axis, i.e. effectively... [Pg.348]

If the activation function is the sigmoid function given in equation (10.56), then its derivative is... [Pg.352]

P is a vector of inputs and T a vector of target (desired) values. The command newff creates the feed-forward network, defines the activation functions and the training method. The default is Fevenberg-Marquardt back-propagation training since it is fast, but it does require a lot of memory. The train command trains the network, and in this case, the network is trained for 50 epochs. The results before and after training are plotted. [Pg.423]

Passive—Minimizing the hazard by process and equipment design features which reduce either the frequency or consequence of the hazard without the active functioning of any device e.g., the use of equipment rated for higher pressure. [Pg.13]

In this case, each site can have many identical outputs but receives only a single input. There are four possible Boolean functions with one input two yield fixed values of 0 or 1, independent of input (these two static functions, and Fi are always among the 2 possible Boolean functions), the third inverts the input T = —) and the fourth is the identity = +). We will discuss behavior arising only ft om the latter two active functions. Exact results for the analytically tractable case of allowing a distribution of all four Boolean functions have been derived by Flyvbjerg and Kjaer [flyvb88]. [Pg.430]

Indeed, the polymeric interface seems to be highly diffuse and hydrophilic because copolymers of N-vinylpyrrolidone and N- (2-hydroxyethyl) acrylamide are readily soluble in water [53]. Besides, aminopropyl-glass adsorbs the acryloyl chloride copolymer so that only 10% of its active functions become amidated. The rest is located on the loops and tails of the attached macromolecules [51]. Thus the steric repulsion of the bonded phase is a probable reason for the high inertness of the packing towards viruses. [Pg.154]

The N-terminal A/B region whose structure has not yet been defined contains a transcriptional activation function, referred to as activation function 1 (AF-1), which can operate autonomously. The length and sequence of the A/B region in the different NRs are highly variable, revealing a very weak evolutionary... [Pg.894]

SHRs are built in a modular structure with similar structure elements. They contain a DNA-binding domain (DBD), a hinge region with a nuclear location signal (NLS), a ligand-binding domain (LBD) and several transcriptional activation functions (Fig. 1). [Pg.1126]

The basic component of the neural network is the neuron, a simple mathematical processing unit that takes one or more inputs and produces an output. For each neuron, every input has an associated weight that defines its relative importance, and the neuron simply computes the weighted sum of all the outputs and calculates an output. This is then modified by means of a transformation function (sometimes called a transfer or activation function) before being forwarded to another neuron. This simple processing unit is known as a perceptron, a feed-forward system in which the transfer of data is in the forward direction, from inputs to outputs, only. [Pg.688]
