Quick post. I just discovered Worlde. The site lets you truth about enzyte generate word clouds from any text.

Continuous-time recurrent ‘neural’ network as a model of intracellular signalling

October 2, 2008 in Experiments, Research, Results, Thoughts, videos | Tags: bacterial chemotaxis, building blocks, CTRNN, intracellular signalling, protein circuit, signalling network | No comments

This is a bit of a long post (took me the better part of today). It shall serve as my initial train of thought on something that I would like to refine, extend, and publish somewhere more seriously. So, if you find the post interesting, and/or you think you can help me shape it such that it becomes so, then don’t hesitate to contact me.

Catching up

July 3, 2008 in Research, Results | Tags: adaptive behavior journal, alife, birmingham, esignet, phd thesis, update, writing | No comments

Getting around to writing this post has taken even longer than the usual. I will attempt to briefly catch up. What have I done so far this year? In terms of writing first.

Thesis, the economy, and writing

December 8, 2007 in Reads, Reflections, Research, Thoughts | Tags: economy, plans, writing | 1 comment

For the last couple of months I have been spending most time working on my thesis. It has been actually very enjoyable, for the most part. There have been some days where it has been somewhat painful. The quick update is that it is going well and that I still hope to submit very soon. As expected, there are many experiments, and tasks, and analysis that I would like to expand into. But I’m going to have to leave it for later. As Inman keeps reminding me, there is no such thing as a finished thesis…

Usual update while ECAL is still fresh in my body

Before I move on to my daily research routine I will first attempt to reflect on the conference. Hopefully this way I can reduce the chances of forgetting it ever happened. I won’t go into much depth but only some of the things I remember most clearly.

A second level of ‘interestingness’ and a more minimal non-monotonic transfer function

June 22, 2007 in Experiments | Tags: chaos, CTRNNs, dynamical systems, monotonic, periodic orbits, point attractors, transfer functions | No comments

The following is a follow-up to my transfer function post a couple of days ago. Two persons have suggested using a simpler non-monotonic function such as the Gaussian. I will incorporate results with that transfer function. Also, I will add one more category to my previous minimalistic categorizationof asymptotic dynamics: point attractors versus other dynamics. I am now including periodic orbits. Still very minimalistic.

Random thoughts

June 21, 2007 in Thoughts | Tags: dynamical system analysis, geometrical explanations, minimal experiments, worries | No comments

I will try to express here two worries that I have had dancing around in my head (and probably body too) for some time now, but which I had not been too explicitly aware of until relatively recently. These preoccupations have arisen from general conversations with people in CCNR-related environments and have occurred with more than one person in different contexts, but it is not aimed at any one person in particular.

A bit more on CTRNN transfer functions

June 20, 2007 in Experiments | Tags: CTRNNs, transfer functions | 2 comments

What effect does the neural transfer function have on the ‘interestingness’ of circuit dynamics? What counts as ‘interesting’ dynamics? I will present here one very simple and very preliminary study that suggests this is worth looking further into.
