Hierarchical Classifier-Regression Ensemble for Multi-Phase Non-Linear Dynamic System Response Prediction: Application to Climate Analysis

12TH IEEE INTERNATIONAL CONFERENCE ON DATA MINING WORKSHOPS (ICDMW 2012), pp. 781–788.

By: D. Gonzalez n, Z. Chen n, I. Tetteh n, T. Pansombut n, F. Semazzi n, V. Kumar, A. Melechko n, N. Samatova n

TL;DR: This paper proposes a hybrid approach that first predicts the phase the system is in, and then estimates the magnitude of the system's response using the regression model optimized for this phase, designed for systems that could be characterized by multi-variate spatio-temporal data from observations, simulations, or both.

Rarefaction and blood pressure in systemic and pulmonary arteries

JOURNAL OF FLUID MECHANICS, 705, 280–305.

By: M. Olufsen n, N. Hill*, G. Vaughan*, C. Sainsbury * & M. Johnson *

author keywords: blood flow
TL;DR: First theoretical calculations of the propagation of the pressure and flow waves along systemic and pulmonary large and small arteries are presented, showing that a decrease of compliance in the large arteries results in pressure increases consistent with observations of isolated systolic hypertension, as occurs in ageing.

When Do Phylogenetic Mixture Models Mimic Other Phylogenetic Models?

SYSTEMATIC BIOLOGY, 61(6), 1049–1059.

By: E. Allman  n, J. Rhodes  n & S. Sullivant n

author keywords: Phylogenetic mixture models; parameter identifiability; heterogeneous sequence evolution
MeSH headings : Algorithms; Computer Simulation; Data Interpretation, Statistical; Models, Biological; Phylogeny
TL;DR: Surveying some of the works on mixture models gives several new results that can serve as a guide to when the use of mixture models in either maximum likelihood or Bayesian frameworks is likely to lead to statistically consistent inference, and when mimicking due to heterogeneity should be considered a realistic possibility.

Pattern Formation in a Model of Acute Inflammation

SIAM JOURNAL ON APPLIED DYNAMICAL SYSTEMS, 11(2), 629–660.

By: K. Penner*, B. Ermentrout & D. Swigon

author keywords: chemotaxis; spatial patterns; mathematical modeling; immunology
TL;DR: By incorporating inhibition (represented by an anti-inflammatory cytokine) into a classical Keller-Segel chemotaxis model, this work creates a novel model that produces a variety of spatial patterns and finds that the dynamical instability in both homogeneous and nonhomogeneous steady states arises only when the inhibitor dynamics are sufficiently slow.
