Giant cross-magnetic-field steps due to binary collisions between pair particles
Article explores giant cross-magnetic-field steps which occur as a result of positron-electron collisions. Within a constant magnetic field (e.g., 1 T), a collision between a positron and an electron can result in a correlated drift across the magnetic field for a continuous range of impact parameters. Within this range, drift distances orders of magnitude larger than that associated with like-charge collisions were observed by computer simulation.

Biocultural conservation in Cape Horn: the Magellanic woodpecker as a charismatic species
This book chapter discusses a research project to promote biocultural conservation in Cape Horn, Chile. In an effort to achieve the goal of transdisciplinary integration, the authors used the strategy of identifying a charismatic species, since doing so serves to motivate people towards biodiversity conservation, to communicate ecological concepts, and to integrate both the ecological and social dimensions of sustainability.

Rate Coefficient Measurements and Theoretical Analysis of the OH + (E)‑CF₃CH==CHCF₃ Reaction
Rate coefficients, k, for the gas-phase reaction of the OH radical with (E)CF3CHCHCF3 ((E)-1,1,1,4,4,4-hexafluoro-2-butene, HFO-1336mzz(E)) were measured over a range of temperatures (211−374 K) and bath gas pressures (20−300 Torr; He, N2) using a pulsed laser photolysis−laser-induced fluorescence (PLP−LIF) technique. k1(T) was independent of pressure over this range of conditions with k1(296 K) = (1.31 ± 0.15) × 10−13 cm3 molecule−1 s−1 and k1(T) = (6.94 ± 0.80) × 10−13exp[−(496 ± 10)/T] cm 3 molecule−1 s−1, where the uncertainties are 2σ, and the pre-exponential term includes estimated systematic error. Rate coefficients for the OD reaction were also determined over a range of temperatures (262−374 K) at 100 Torr (He). The OD rate coefficients were ∼15% greater than the OH values and showed similar temperature dependent behavior with k2(T) = (7.52 ± 0.44) × 10−13exp[−(476 ± 20)/T] and k2(296 K) = (1.53 ± 0.15) × 10−13 cm3 molecule−1 s−1. The rate coefficients for reaction 1 were also measured using a relative rate technique between 296 and 375 K with k1(296 K) measured to be (1.22 ± 0.1) × 10−13 cm3 molecule−1 s−1, in agreement with the PLP−LIF results. In addition, the 296 K rate coefficient for the O3 +( E)CF3CHCHCF3 reaction …

Lessons Learned: Digitization of Cooke County Ledgers
This paper describes a grant project to digitize Cooke County, Texas ledgers. The project was funded in part by the National Historic Publications and Records Commission (NHPRC) and involves digitizing and hosting several rare and unique collections representative of the Civil War. The UNT Archives partnered with the UNT Libraries Digital Projects Unit (DPU), which managed all stages of the digitization. This paper describes and examines the process the DPU implemented to digitize the Cooke County ledger collection; in doing so, it provides insight into the problems one might encounter, as well as recommendations for institutions that may be considering similar digital projects.
