Catastrophists love frozen woolly mammoths. It doesn’t matter what their preferred catastrophe is–Atlantis sinking, falling ice moons, the Noachian flood, abrupt changes of the Earth’s axis, or a near miss by a pinballing planet disguised as an ancient Near Eastern god–at some point, they will trot out the frozen mammoths as proof positive of their theory. . . . → Read More: Blood of the Mammoth...

Most of the detergents that are in use today were available 5 or 10 years ago. Maybe the purity has increased over time, but the list of detergents extracted from successfully crystallized membrane proteins really hasn't seen any substantial additions in the past few years. In the previous blog "Applying the 80/20 rule to membrane protein crystallization pre-screening" I showed a list of detergents and referenced statistics that show that with just 8 detergents (dodecyl maltoside, decyl maltosid........

After the last more general entries on managers perception of risk and measuring SC performance I wanted to make a detour back to the basics.
Simulation is one of the tools, which can be used for analyzing supply chain dynamics, optimization and to support corporate decision making.
One major question when starting a supply chain model has always been what level of detail should you choose? Someone could start with a single worker in an agent based simulation model and continue with the mac........ Read more »

Today being Thanksgiving, it's pretty reasonable to assume (if you live in the U.S.) that you will likely be sitting down to a large meal involving lots of turkey, stuffing, and cranberry sauce. It is also pretty likely, that somewhere in the house, football games will be on the television. Which brings us to one of the quintessential questions in football: It's 4th down, your team is on the opposing team's 30 yard line and they have only one yard to go to get a first down. Sho........

Dr. Kevin Mitchell, a neuroscientist at Smurfit Institute of Genetics, University of Dublin, posted at his excellent blog Wiring the Brain about a weird, interesting study* that points to a possible genetic explanation of synaesthesia** (e.g., hearing a word and experience the color red). The authors were studying pain mechanisms in fruit flies (turns out the mechanisms are similar to us mammals, whuddathunk?). Once they identified a particular gene they dubbed straightjacket*** which is "involv........ Read more »

Last week I conducted another Interview for the empirical part of my research. And we also discussed how to measure performance within the SC. As it turns out, multiple measures, namely service, cost, working capital are used. Sadly in literature many authors still focus on a single measure only and I wanted to know more about it. So I read an article by B. Beamon (Measuring Supply Chain Performance) to get an overview over performance measures used and how to select the right one(s).

We've all heard about autistic "savants" with amazing mathematical, memory or artistic abilities. But could autism give you the power to kill 1,000 men armed only with a donkey bone?Samson was the original Chuck Norris. Granted mighty strength by God so long as he didn't cut his hair or shave, Samson's first act of heroism was ripping a lion to shreds with his bear hands. Then he moved onto people. According to the Book of Judges:"And Samson said, With the jawbone of an ass, heaps upon heaps, wi........ Read more »

The Naming Game looks at how communication systems evolve in populations of agents.
