Kids love models, and on page 792 of this issue Shimizu et al. give us an early Christmas present. Using plastic replicas of the CheA, CheW, and Tsr protein structures, they assembled the pieces like a jigsaw puzzle.

Model World: A Model Is a Model Is a Model Is a Model
Interfaces, 1989This occasional column will address issues — both real and imaginary — that impinge on what I think is the main activity of management science/operations research: building models that attempt to describe the world as it was, as it is, and as it will be.

Advances in Applied Probability, 1978
Ising lattices model spatial interaction among binary variables, and consequently, are relevant to many scientific disciplines. They are intuitively appealing models because their conditional distributions are given locally (they are Markov fields). On the other hand, their marginal distributions (even for pairs of sites, let alone triples, etc.) are ...

Physical Review B, 1995
We consider the phase diagram of two randomly coupled Ising models to mimic the successive phase transitions in plastic crystals. Detailed mean-field calculations are performed. Depending on the strength of the couplings, the phase diagrams display three ordered phases and some multicritical points.

Ising ferrimagnetic models. II
Journal of Physics C: Solid State Physics, 1974In the systems considered the lattice is divided into sub-lattices of Na and Nb sites occupied by spins of magnetic moment mu a and mu b respectively such that Na mu a not=Nb mu b. The exchange interactions tend to line up the a and b spins in opposite directions.

Inhomogeneous critical Ising model
Physical Review Letters, 1990The spectrum of the transfer matrix of a semi-infinite two-dimensional Isin model with marginally inhomogeneous couplings has been determined exactly in the finite-size-scaling limit at the bulk critical point. Depending on the local temperature at the boundary the surface phase transition of this system is either of first order or of second order with

Business Modelling Is Not Process Modelling
2000Innovative e-business projects start with a design of the e-business model.We often encounter the view, in research as well as industry practice, that an e-business model is similar to a business process model, and so can be specified using UML activity diagrams or Petri nets. In this paper, we explain why this is a misunderstanding.

What Model Is the “Ising Model?”
The Ising model is one of the most studied models in modern physics. However, the question of what model is the Ising model is a subject of disagreement in the philosophical litera- ture. For some, it is a toy model (e.g., Reutlinger, Hangleiter and Hartmann 2018), while for others, it is a minimal model (e.g., Elliott-Graves and Weisberg 2014 ...Rodriguez, Quentin, Ardourel, Vincent

Journal of NeuroInterventional Surgery, 2012
I read with interest the paper by Kerber et al entitled ‘1-Hexyl n- cyanoacrylate compound (Neucrylate AN), a new berry aneurysm treatment. II. Rabbit implant studies: technique and histology.’1 As suggested by the title, the paper focuses on the preclinical evaluation of a new device in a rabbit model.
