Generic Rigidity Matroids with Dilworth Truncations [PDF]

open access: yes, 2012
We prove that the linear matroid that defines generic rigidity of $d$-dimensional body-rod-bar frameworks (i.e., structures consisting of disjoint bodies and rods mutually linked by bars) can be obtained from the union of ${d+1 \choose 2}$ graphic ...

Louse (Insecta : Phthiraptera) mitochondrial 12S rRNA secondary structure is highly variable [PDF]

open access: yes, 2002
Lice are ectoparasitic insects hosted by birds and mammals. Mitochondrial 12S rRNA sequences obtained from lice show considerable length variation and are very difficult to align.

Deciphering acoustic emission signals in drought stressed branches: the missing link between source and sensor [PDF]

open access: yes, 2015
When drought occurs in plants, acoustic emission (AE) signals can be detected, but the actual causes of these signals are still unknown. By analyzing the waveforms of the measured signals, it should, however, be possible to trace the characteristics of ...

Disorder induced transitions in layered Coulomb gases and application to flux lattices in superconductors

open access: yes, 2004
A layered system of charges with logarithmic interaction parallel to the layers and random dipoles in each layer is studied via a variational method and an energy rationale. These methods reproduce the known phase diagram for a single layer where charges

The Invention of Sugaring for Moths in Ninetheeth-Century England [PDF]

open access: yes, 2017
[excerpt] Those who find enjoyment in the books of P. B.M. Allan have had at least an introduction to the history of our familiar method of using artificial bait to attract nocturnal Lepidoptera (Allan, 1937, 1943, 1947).

Complete genome sequence of Syntrophobacter fumaroxidans strain (MPOB(T)). [PDF]

open access: yes, 2012
Syntrophobacter fumaroxidans strain MPOB(T) is the best-studied species of the genus Syntrophobacter. The species is of interest because of its anaerobic syntrophic lifestyle, its involvement in the conversion of propionate to acetate, H2 and CO2 during ...

Cholesteric order in systems of helical Yukawa rods

open access: yes, 2010
We consider the interaction potential between two chiral rod-like colloids which consist of a thin cylindrical backbone decorated with a helical charge distribution on the cylinder surface. For sufficiently slender coiled rods a simple scaling expression

Statics and dynamics of the Lebwohl-Lasher model in the Bethe approximation

open access: yes, 2006
We study the Lebwohl-Lasher model for systems in which spin are arranged on random graph lattices. At equilibrium our analysis follows the theory of spin-systems on random graphs which allows us to derive exact bifurcation conditions for the phase ...

Complete genome sequence of the Medicago microsymbiont Ensifer (Sinorhizobium) medicae strain WSM419 [PDF]

open access: yes, 2010
Ensifer (Sinorhizobium) medicae is an effective nitrogen fixing microsymbiont of a diverse range of annual Medicago (medic) species. Strain WSM419 is an aerobic, motile, non-spore forming, Gram-negative rod isolated from a M.

Dimensional Reduction for Directed Branched Polymers

open access: yes, 2004
Dimensional reduction occurs when the critical behavior of one system can be related to that of another system in a lower dimension. We show that this occurs for directed branched polymers (DBP) by giving an exact relationship between DBP models in D+1 ...
