Seven challenges for model-driven data collection in experimental and observational studies
Epidemics, 10, 78–82.
author keywords: Modeling; Data collection; Observational studies; Experimental studies
MeSH headings : Communicable Diseases / epidemiology; Communicable Diseases / transmission; Data Collection / methods; Epidemiologic Research Design; Humans; Models, Statistical; Observational Studies as Topic / methods

ORTHOGONAL LOW RANK TENSOR APPROXIMATION: ALTERNATING LEAST SQUARES METHOD AND ITS GLOBAL CONVERGENCE
SIAM JOURNAL ON MATRIX ANALYSIS AND APPLICATIONS, 36(1), 1–19.
Contributors: L. Wang, M. Chu* & B. Yu
author keywords: orthogonal tensor decomposition; low rank approximation; alternating least squares; high-order power method; polar decomposition; global convergence; Zariski topology

Nine challenges for deterministic epidemic models
Epidemics, 10, 49–53.
author keywords: Deterministic models; Endemic equilibrium; Multi-strain systems; Spatial models; Non-communicable diseases
MeSH headings : Communicable Diseases / epidemiology; Communicable Diseases / transmission; Endemic Diseases / statistics & numerical data; Epidemics / statistics & numerical data; Epidemiologic Factors; Humans; Models, Statistical; Stochastic Processes; Superinfection
TL;DR:
The need for models that describe multi-strain infections, infections with time-varying infectivity, and those where super infection is possible is indicated, and the need for advances in spatial epidemic models is considered.

NONCROSSING ARC DIAGRAMS AND CANONICAL JOIN REPRESENTATIONS
SIAM JOURNAL ON DISCRETE MATHEMATICS, 29(2), 736–750.
Contributors: N. Reading*
author keywords: canonical join representation; lattice congruence; noncrossing arc diagram; permutation; weak order
TL;DR:
This work considers two problems that appear at first sight to be unrelated, but turn out to be closely related because the noncrossing arc diagrams provide a combinatorial model for canonical join representations.

Five challenges for stochastic epidemic models involving global transmission
EPIDEMICS, 10, 54–57.
author keywords: Stochastic epidemics; Global transmission; Extinction; Genetic evolution; Endemicity
MeSH headings : Biological Evolution; Communicable Diseases / epidemiology; Communicable Diseases / transmission; Endemic Diseases / statistics & numerical data; Epidemics / statistics & numerical data; Extinction, Biological; Global Health / statistics & numerical data; Humans; Models, Statistical; Stochastic Processes
TL;DR:
The most basic stochastic epidemic models are those involving global transmission, meaning that infection rates depend only on the type and state of the individuals involved, and not on their location in the population.

A Mathematical Model for SAR Imaging beyond the First Born Approximation
SIAM Journal on Imaging Sciences, 8(1), 186–225.
author keywords: synthetic aperture imaging; SAR ambiguity theory; linearized scattering; linearized inverse problem; backscattering; Bragg resonance; weak scattering; strong scattering
