            deSolve ODE Integration Error, am I using the wrong function?
            Asked 2021-Jun-06 at 16:48

            I'm attempting to solve a set of equations related to biological processes. One equation (of about 5) is for a pharmacokinetic (PK) curve of the form C = Co(exp(k1*t)-exp(k2*t). The need is to simultaneously solve the derivative of this equation along with some enzyme binding equations and initial results where not as expected. After troubleshooting, realized that the PK derivative doesn't numerically integrate by itself, if k is negative using the desolve ode function. I've attempted every method (lsode, lsoda, etc) in the ode function, with no success. I've tried adjusting rtol, it doesn't resolve.

            Is there an alternative to the deSolve ode function I should investigate? Or another way to get at this problem?

            Below is the code with a simplified equation to demonstrate the problem. When k is negative, the integrated solution does not match the analytical result. When k is positive, results are as expected.

            First Image, result with k=0.2: Analytical and Integrated results match when k is positive

            Second Image, result with k=-0.2: Integrated result does not match analytical when k is negative

            How do i select text with regex based on tag and class content in html?
            Asked 2021-Jun-01 at 16:52

            I have an html tag as a string. If 'md' is included in the class attribute in this tag, I want to select it and get the expression in the tag.

            Example:

            '(expression)

            • is first selector
            • Class attribute included md is second selector
            • At the same time, the tag should not be empty.

            I mean, I need a regex that starts with and ends with and gives tag with md in class attribute, but I couldn't get out of it.

            What I did is trying to select those with direct md attribute, but this is wrong. Also problem with nested tag ones as well.

            ODEINT - Different results when new equations added
            Asked 2021-May-28 at 14:58

            hope you're all fine.

            That's my first question, so I'm sorry if something's not right about it.

            I'm studying numerical stability and chaoticity of some dynamical systems, more specifically, about the Circular Restricted Three Body Problem (CR3BP), defined by the set of 3 second order differential equations. After transforming those three second order differential equations in six first order differential equations as seen here i can finally finally work with them numerically using scipy's ODEINT. Here's an example of an orbit integrated for T = 2^10 with n = 2^18 points (np.linspace(1, 2^10, 2^18)) and here's a bit of my code for this, the main function to be integrated:

            ANSWER

            Answered 2021-May-28 at 07:13

            This is probably due to the step size control being also influenced by the rapidly growing v vector. Either by regulating step sizes rapidly down due to stiffness, or more likely, due to increasing the step size to match the dominant components, thus becoming unsuitable for an exact integration of the original trajectory. This rapid growth is the reason that Lyapunov exponents were introduced, as they capture this growth in nicely bounded numbers.

            What you can do is to split up the integration into smaller chunks and normalize the v vector at the start of each chunk. One would have to experiment on how long it takes until the v component unduly dominates the step size control. As the coupling is purely multiplicative, the dynamic theoretically is linear. So it could also help if you scale the initial v to have norm 1e-100.

            First however check what error tolerances you use. Setting them narrower also tends to stabilize the computation. You might also get some progress be setting the maximal step size hmax to half or so of the external step.

            Or you could do the Lyapunov exponent computation like I explored in https://scicomp.stackexchange.com/questions/36013/numerical-computation-of-lyapunov-exponent. This approach however increases a system of dimension n by the n x n matrix of eigen/singular vectors and the n products of exponents times time.

            When using recursion you need to do something with the result and return a value accordingly otherwise nothing will happen. In the code below we use the return statement to make a chain of people between the ancestor and the descendant. I have annotated what additional steps need to be taken in the code below. The key part is String result = getOneAncestor(...) and return result + " born of " + ancestor.name; as shown here:

            React Native use Context in helper api file from within different exported functions
            Asked 2021-May-01 at 20:36

            I have a helper file with some exported functions. And I have a ContextProvider with some shared data. Now I need to change the Data in the Context from inside the helper functions.

            But there are errors if I call the useContext statement inside the function bodys and also if I do it outside.

            If I create one default function MyHelper() in the helper file I can call the useContext inside and its working. But then I can't use different functions as api from another file. Only the MyHelper().

            How can I call more than one exported functions in another .js File and also change there context data?

            The reason you see the error is that you are calling a hook outside of the component body. In your case that is the useContext hook. In the first case you are calling it on a module level and in the other two cases you call it inside of a function but then you call that function in a handler which is also "outside" of the component. What you need to do is to extract a hook that you call unconditionally in your component. That hook can expose (return) a function that you can call in your handler.

            You can create your own custom hooks which are composed from other hooks:
