On the Tutte-Krushkal-Renardy polynomial for cell complexes [PDF]
Recently V. Krushkal and D. Renardy generalized the Tutte polynomial from graphs to cell complexes. We show that evaluating this polynomial at the origin gives the number of cellular spanning trees in the sense of A. Duval, C. Klivans, and J.

Polynomial functors and polynomial monads
We study polynomial functors over locally cartesian closed categories. After setting up the basic theory, we show how polynomial functors assemble into a double category, in fact a framed bicategory.

Comparison and Analysis of Geometric Correction Models of Spaceborne SAR
Following the development of synthetic aperture radar (SAR), SAR images have become increasingly common. Many researchers have conducted large studies on geolocation models, but little work has been conducted on the available models for the geometric ...

Safety Margin Prediction Algorithms Based on Linear Regression Analysis Estimates
In this paper, we consider the problem of approximating the safety margin of a single instance of a technical system based on inaccurate observations at specified time points.

On Polynomials Which Commute with a Given Polynomial [PDF]
By extending a theorem of Jacobsthal, the following result is obtained: if g is a nonlinear polynomial, there is an integer J ( g ) ≧ 1 J(g) \geqq 1 such that for each m > 0 m > 0 there are either J ( g )

Diffusion‐based size determination of solute particles: a method adapted for postsynaptic proteins
We present a diffusion‐based approach for measuring the size of macromolecules and their complexes, and demonstrate its use on postsynaptic proteins. The method requires fluorescein‐labelled protein samples, a microfluidic device that maintains laminar flow for said samples, a microscope recording the emitted fluorescent signals, and an analytic ...
