Tailoring triaxial N -body models via a novel made-to-measure method
The made-to-measure N -body method (Syer & Tremaine 1996) slowly adapts the particle weights of an N -body model, whilst integrating the trajectories in an assumed static potential, until some constraints are satisfied, such as optimal fits to observational data. I propose a novel technique for this adaption procedure, which overcomes several limitations and shortcomings of the original method....
متن کاملLimbs Made to Measure
This year marks the 150th anniversary of the birth of D’Arcy Thompson, the British biologist, classicist, and all round polymath (For more information on D’Arcy Thompson see www. darcythompson.org). Like many, he was fascinated by the appearance and structure of living matter, and in his influential book, On Growth and Form [1], he set out to describe and explain the principles of morphogenesis...
متن کاملMade to measure?
324 British Journal of General Practice, June 2013 My next patient walks in confidently wearing a big smile. All the training I’ve done in non-verbal communication kicks in and I suspect that his depression is starting to get better. He hands me a PHQ-9 with a flourish which confirms my initial impressions. I’m usually sceptical of these scoring tools, but this is no ordinary PHQ-9, this a luxu...
متن کاملVisualizing Astrophysical N-body Systems
I begin with a brief history of N-body simulation and visualization and then go on to describe various methods for creating images and animations of modern simulations in cosmology and galactic dynamics. These techniques are incorporated into a specialized particle visualization software library called MYRIAD that is designed to render images within large parallel N-body simulations as they run...
متن کاملMade to measure – keeping Rho kinase at a distance
The Rho-associated coiled-coil containing kinases (ROCK) were first identified as effectors of the small GTPase RhoA, hence their nomenclature. Since their discovery, two decades ago, scientists have sought to unravel the structure, regulation, and function of these essential kinases. During that time, a consensus model has formed, in which ROCK activity is regulated via both Rho-dependent and ...
