== Experiment Sign-up ==

http://tuvalu.santafe.edu/events/workshops/index.php/Experiment_sign-up

== Can one get a chaotic map with two disco balls? ==

And, if so, isn't it practically our duty to do so?

(There's a disco ball in the lecture hall.)

== Schooling interactions with non-square boundary ==
The Monterey Bay Aquarium has an [http://www.youtube.com/watch?v=xZKxfvi9h0c [anchovy tank]] shaped like two nested sections of cones (you stand inside it). Boid-like behavior is pretty easy to see in the fish, particularly because the shape of the tank interferes with the school. I couldn't decide if the tank was actually inducing turbulence in the fish.

== Dynamical Systems: R and Python ==
I wrote some Python code for simulating deterministic dynamical systems and used it to play around with the Logistic map from yesterday's lectures. The Python class I wrote for simulating generic dynamical systems (admittedly only those with a single state variable!) can be found [https://sites.google.com/site/beyondmicrofoundationscoderepo/home/python/dynamics here] (I would have posted to the code to the wiki directly but apparently one cannot upload .py files). I have also written a [http://beyondmicrofoundations.blogspot.com/2012/06/monday-4-june-2012-at-2012-csss.html blog] post demonstrating some of the functionality of the Python code.

Also, there are several R packages that seem to implement the algorithms from the TISEAN program that we were introduced to yesterday. The packages are [http://cran.r-project.org/web/packages/RTisean/index.html RTisean], [http://cran.r-project.org/web/packages/tseriesChaos/index.html tseriesChaos], and [http://cran.r-project.org/web/packages/tsDyn/index.html tsDyn] and can be found on CRAN.

Enjoy,

D. Pugh

PS: I am very much a newbie to Python, and any suggestions on improving my coding are much appreciated!

I have written another blog [http://beyondmicrofoundations.blogspot.com/2012/06/5-6-june-2012-at-2012-csss.html post] and some more Python code for implementing parts of the TISEAN labs that we have been assigned. Code can be found here [https://sites.google.com/site/beyondmicrofoundationscoderepo/home/python/dynamics here]. Eventually, the code will contain solutions to the all of the labs and homework.

== Python wrapper for TISEAN ==

Thanks for sharing your python code David.

Incidentally there is also a Python wrapper for TISEAN available
[http://www.stud.fernuni-hagen.de/q4576411/andreas_2/computer/projekte/tisean.html here]. Not sure how good it is, but might be worth checking out.

Complex Systems Summer School 2012-Project Presentations

{{Complex Systems Summer School 2012}}

Use this space to post project presentations and outlines. Include group members, a brief outline, and your slides.

=== Price-time Dynamics of Contracts Traded on Prediction Markets ===

Joanne, Vikram, Matteo, Sanith

Prediction markets have been shown to outperform traditional methods of polls and opinion surveys in forecasting future events. The futures contracts traded in these markets assess the expectation of occurrence of a variety of events spread across multiple domains (political, economic, entertainment, financial and weather). We explore the feasibility of 'predicting' the outcome of binary true/false prediction market contracts ahead of their expiry date using a neural-network based machine learning approach. In addition we focus on the characteristics of political-based contracts to establish whether they exhibit characteristic 'fundamental' properties.

=== How Complex Languages Replicate through Simple Brains ===

Katrien, Vanessa, Sandro, Cameron, Jasmeen

Through the use of an iterated learning experiment, we investigated the transmission of a "high entropy", randomised initial language through successive generations of participants. We want to see what features of the language replicated most easily, and what structure emerged by the end of the chain. Our hypothesis is that the language converges to a "low entropy" equilibrium state with a minimal number of words, morphemes, and form-meaning distinctions.

=== Collaboration in times of stress: an Agent Based Modelling approach ===

Fabio Cresto Aleina, Elena del Val, Tom Fennewald and Friederike Greb

We want to investigate the influence of exogenous stress on cooperative behaviour. We propose an agent based model in which the agents can be interpreted as farmers living in a water limited environment. With changes in precipitation patterns, the farmers undergo stress, and we observe how this impacts relationships among farmers and their properties.

=== Simple variation of the logistic map as a model to invoke questions on cellular protein trafficking ===
(Sepehr Ehsani, http://arxiv.org/abs/1206.5557)

Many open problems in biology, as in the physical sciences, display nonlinear and 'chaotic' dynamics, which, to the extent possible, cannot be reasonably understood. Moreover, mathematical models which aim to predict/estimate unknown aspects of a biological system cannot provide more information about the set of biologically meaningful (e.g., 'hidden') states of the system than could be understood by the designer of the model ab initio. Here, the case is made for the utilization of such models to shift from a 'predictive' to a 'questioning' nature, and a simple natural-logarithm variation of the logistic polynomial map is presented that can invoke questions about protein trafficking in eukaryotic cells.

===Changes in Social Network Structure in Response to Crisis: Using Twitter data to Explore the Effect of the Tōhoku Earthquake.===

Christa Brelsford and Xin Lu

Abstract:
We use twitter data from 7 days before and after the Tōhoku Earthquake to explore how cooperation rates, social network structure and connectivity, and social network vulnerability changed in Japan in response to the disaster. An English language data set is collected for the same time period to use as a control. Data is collected for a period of 96 hours starting from March 4th 2011 2:46pm JST and for 96 hours beginning March 11th 2011 2:46 pm JST. The rate of cooperative behavior, measured by the occurrence of helping words in tweets increases slightly in the English dataset and by an order of magnitude in the Japanese dataset. A network analysis is also performed. Network edges are retweets and direct messages. In future work, we hope to explore whether problem solving capacity in a social system changes in response to crises, based on changes in the rate of cooperation and information transfer in a network.

=== The CSSS Network ===

Tom & Riccardo (with JP and others)

We will investigate the questions you are dying to know: What interesting interactions are revealed from the first 3 weeks of the Complex System Summer School survey? Have barriers between academic disciplines been broken down? Do power laws fit the data!? ...

Let us know if you have specific questions or if you would like to be involved in data analysis!

=== Is there a method in the madness? the dynamic structures of human language use ===

Priya and Riccardo

Psychiatric anecdotal reports point to the monotony, lack of emotion and sometimes intelligibility in many clinical populations. Linear measures of fluency and prosody, however, present only controversial differences between patients and healthy controls and only in unnatural phonations (i.e. say "aaaaa" for 30 secs).
We therefore go complex and chaotic on a set of more ecological recordings and transcriptions from 4 clinical populations (Asperger's, Schizophrenics, Depressed and Right Hemisphere Damage patients) as well as from healthy controls.
We then set a classifier-driven race: will non-linear analyses outcompete linear analyses in discriminating between pathologies?

=== Escaping the Poverty Trap: Modeling the Interplay Between Economic Growth and the Ecology of Infectious Disease ===

Georg, Ben, Laurent, Oscar

The dynamics of economies and infectious disease are inexorably linked: economic well-being influences health (sanitation, nutrition, etc) and health influences economic well-being (labor productivity lost to sickness and disease). Often societies are locked into "poverty traps" of poor health and poor economy. Here, we demonstrate poverty traps formed in models of infection and endogenous growth, as well as ways to break out of poverty traps. We explore two mechanisms of escape: one, through an influx of capital, and another through changing the percentage of GDP spent on healthcare. We find large influxes of capital is successful, but increasing health spending does not. Our results have important policy implications in the distribution of aid and within-country healthcare spending.

=== The Targeting and Timing of Treatment Influences the Emergence of Influenza Resistance in Structured Populations ===

Ben, Laurent, Oscar, Georg

Evolution of antiviral resistance in influenza carries large societal impacts through morbidity and mortality caused by treatment failure. Several previous studies put forth theory regarding the optimal timing, targeting and absolute level of treatment in populations. Few of these studies, however, have considered populations with explicit structure. Here we present a model of antiviral resistance on networks and explore the timing, targeting and levels of treatment. Interestingly, we find bistability as a result of treatment leading to the existence of an unstable manifold, above which successful treatment (i.e.: no resistance) is impossible. We find, contrary to previous results, that degree-targeted treatment is not optimal, and leads to higher levels of resistance than random treatment. Additionally, in accordance with previous results, we find an optimum level of treatment which is less than 100%. These findings findings have important consequences in guiding policy behind influenza treatment. The bistability indicates that caution should be taken when treating populations when the absolute numbers of infections are unknown. Positively, our results indicate that putting resources into targeted treatment is not necessary, random treatment is preferable.

=== Learning in Random Boolean Networks ===

Nick A., Keegan, Matteo, Vikram, Sarah, Mark

Inspired by biochemical networks which adapt on evolutionary timescales, neural networks that adapt during development and learning, and universal computation in cellular automata, we have implemented several models of learning in Random Boolean Networks (RBNs) in order to better understand the relationships between network structure, node interaction rules, and network output.

=== Enzyme Catalysis and the Outcome of Chemical Reactions ===
Piotr and Georg W.
Enzymes are catalysts that accelerate chemical reactions but do not affect their outcome. This traditional paradism was developed under artificail test tube conditions. Our project investigates the possibility that the presence of an enzyme can alter the course of a reaction if it takes place under more physiologic conditions.

==Order Book Dynamics: Learn how to trade in 15min==

--I'm happy to repeat this -just get in touch with me.--

If you are curious about how stocks trade and want to try your luck, I'll
be going over some of the basics with a hands-on example.

Meet at 7.30pm in main lecture hall Thursday June 7th. Please make sure
to bring your laptop.

Sanith

==Update==

Hi guys

I guess the mail lecture hall is free at 6.30 pm and so we can meet there. I have a small talk through the idea and then maybe we can try out getting bifurcation plots for one or two systems. I use software written in MATLAB for the demo but the idea can be implemented in any software.

Here's a link to the [[software for numerical continuation|http://twr.cs.kuleuven.be//research/software/delay/notice.shtml]]. This software can handle systems with time delays and can be used to obtain the bifurcation behaviour.

(1) Please download the software DDE-BIFTOOL and unzip.

(2) Within the folder, you will find another zipped folder in small case ‘ddebiftool’. Please unzip this into a folder with the same name

(3) Add the location of the folder to the path of MATLAB.
I have also sent out a mail with a zipped folder containing files to get a bifurcation plot for a Rijke tube system.
Do let me know if anyone did not get this.
See you there!

Priya

==An easier way to get a bifurcation plot==

Hey guys
I have been working in the past in obtaining bifurcation plots for different physical systems. There's a better way to get these pictures instead of getting the evolution at every parameter value of interest. This is called ''numerical continuation'' and basically involves tracking a curve. I plan to give a informal talk on how to do this and maybe even a demo on applying this technique on 14th June at 6.30 pm. Do mail me if you are interested at '''iitm.priya@gmail.com''' or sign up below.

==Using Tisean on R on OS X==
first install TISEAN, like you've done already. Make sure R is up to date (v 2.15).
you can try to install RTisean from CRAN
install.packages("RTisean"); library(RTisean); henon()
But me and Dave both got an error about some bad file name, something about con and something about a long path involving -Tmp-
Solution:
remove.packages("RTisean")
restart R
download this: http://cl.ly/0I0b2P2L311y1q0q0y0n
install it, it changes line 74 of nativeTISEAN.R which has some problems with file handling
If you are golden, then:
> henon()
V1 V2
[1,] -0.1232481 -1.030383

==A conceptual shell==

One thing that I think has been missing from this course is an explicit set of concepts and tools which we can use to relate all of the talks we've been listening to. Last fall, two other graduates students and I taught a survey course on complexity. We put together the following document, which contains one-paragraph summaries of what we felt were the 20 most important concepts that comprised the field of complexity. These were the "glue" that we used to relate all of our lectures and workshops. Most of these will probably be familiar to you, but I think they serve as a nice, concise reference and may be helpful in tying all of this information overload together. One caveat: These are works in progress and are in alphabetical rather than any logical conceptual order.

I guess the mail lecture hall is free at 6.30 pm and so we can meet there. I have a small talk through the idea and then maybe we can try out getting bifurcation plots for one or two systems. I use software written in MATLAB for the demo but the idea can be implemented in any software.

Here's a link to the [[software for numerical continuation|http://twr.cs.kuleuven.be//research/software/delay/notice.shtml]]. This software can handle systems with time delays and can be used to obtain the bifurcation behaviour.

(1) Please download the software DDE-BIFTOOL and unzip.

(2) Within the folder, you will find another zipped folder in small case ‘ddebiftool’. Please unzip this into a folder with the same name

(3) Add the location of the folder to the path of MATLAB.
I have also sent out a mail with a zipped folder containing files to get a bifurcation plot for a Rijke tube system.
Do let me know if anyone did not get this.
See you there!

Priya

==An easier way to get a bifurcation plot==

Hey guys
I have been working in the past in obtaining bifurcation plots for different physical systems. There's a better way to get these pictures instead of getting the evolution at every parameter value of interest. This is called ''numerical continuation'' and basically involves tracking a curve. I plan to give a informal talk on how to do this and maybe even a demo on applying this technique on 14th June at 6.30 pm. Do mail me if you are interested at '''iitm.priya@gmail.com''' or sign up below.

==Using Tisean on R on OS X==
first install TISEAN, like you've done already. Make sure R is up to date (v 2.15).
you can try to install RTisean from CRAN
install.packages("RTisean"); library(RTisean); henon()
But me and Dave both got an error about some bad file name, something about con and something about a long path involving -Tmp-
Solution:
remove.packages("RTisean")
restart R
download this: http://cl.ly/0I0b2P2L311y1q0q0y0n
install it, it changes line 74 of nativeTISEAN.R which has some problems with file handling

Every year we have a T-shirt design contest, where CSSS Students create designs (relevant to the summer school) and during the end of the second week we vote on the one we will print and distribute to the cohort. Please post your T-shirt design below. The design will be printed on a single colored T-shirt (keep in mind which color T-shirt you would like to print on while planning your design). The print that will go on the T-shirt is limited to a two color back and a one color front.

Have fun and be creative!

Urania blowing seeds of complexity

This is a draft I prepared a late evening some time before the CSSS. I didn't know at that time that the dorms have muse names and that I'll end up in the Urania...

Urania was the muse of Astronomy and also the Muse of Mathematics. she was often depicted holding a globe in her hands. In this case the cubist face and hands of Urania are borrowed from Picasso and she holds a SFI globe/dandelion flower head, on which she blows in order to disperse the seeds of complexity.

In my view this would need some serious polishing and volunteers to do so are welcome! Feedbacks also!

Cheers, Nick Goudemand

Crystals are a prime manifestation of complexity. The design (front and back) represents crystals grown in cell culture dishes as seen under the microscope. The picture on the right has been mapped on a canvas with polar coordinates to show more symmetrical structure and avoid having a beginning and an end. (One from Georg Weber)

* nonequilibrium game theory --- my plan is to adapt some SFI-based models, by people like Crutchfield and Farmer, so that they will quantitatively or qualitatively reproduce features of real human data. Meet Seth Frey at dinner on Thursday and Friday.
* Enzyme kinetics – Do enzymes just accelerate equilibrium or play an active role in chemical reactions?
Enzyme networks (e.g. glycolysis) and catalysts in complex mixtures (e.g. Belusov-Zhabotinski reaction) can profoundly influence the outcome of a chemical reaction system. What about a single enzyme? Biochemistry textbooks uniformly say that an enzyme accelerates a reaction without altering its outcome. Yet, the set of differential equations that generically describes enzyme catalysis has remarkable resemblance to the Roessler equations (a textbook example of a non-linear, complex system). With a fixed substrate input or a steady substrate flow, a single enzyme probably cannot affect the reaction outcome. However, sinusoidal or pulsating substrate input, substrate activation or product inhibition, coupling of two enzymes could turn the reaction pattern non-linear. For this project, the sets of equations to study are quite well established – they need to be analyzed. In contrast to some of the more ambitious ideas circulated, this task is exhaustively doable in less than four weeks.
I am Georg Weber. If you are interested in studying this problem, please find me on Tuesday over lunch or dinner (or talk to me at any other unstructured time).

Georg F. Weber

2012-05-08T20:41:43Z

WeberG:

Georg F. Weber (born in Germany, now on the faculty in Cincinnati) is a cancer researcher, who has made contributions to the exploration of metastasis by defining the physiologic role of metastasis genes and by discovering the interaction between the molecules osteopontin and CD44. Georg has defined the genetic basis of metastasis formation as aberrant expression or splicing of a unique set of developmentally non-essential genes (stress response genes) that physiologically mediate the directed migration of immune system cells.
Early in his intellectual life, Georg wrote publications on chess and biomechanics. His medical career was initially focused on immunology, in particular on the regulation of host defenses through redox mechanisms. Among various phenomena, he identified signal transduction pathways inside T-lymphocytes that determine cell proliferation, programmed cell death, or immunosenescence. Georg’s enthusiasm for complexity research is based in part on his medical research and in part on his philosophical interests.
