Bayesian Time-Series Models in Single Case Experimental Designs: A Tutorial for Trauma Researchers

Article discusses the utility of SCED data for trauma research, provides recommendations for addressing challenges specific to SCED approaches, and introduces a tutorial for two Bayesian models—the Bayesian interrupted time-series (BITS) model and the Bayesian unknown change-point (BUCP) model—that can be used to analyze the typically small sample, autocorrelated, SCED data.

Confinement of antiprotons in the electrostatic space charge of positrons in a model of the ALPHA antihydrogen trap (open access)

Confinement of antiprotons in the electrostatic space charge of positrons in a model of the ALPHA antihydrogen trap

This article details the equilibrium of a positron plasma in a model of the ALPHA apparatus that is computed using a finite-difference method. The positron plasma in the model extends to axial magnetic mirrors in absence of an octupole field. Formation of a three-dimensional electrostatic potential well is found to occur self-consistently. Well depths under various conditions are evaluated. Also, the equilibrium with an antiproton plasma confined in the potential well is computed.

A random walk version of Robbins' problem: small horizon (open access)

A random walk version of Robbins' problem: small horizon

This article considers an analogous problem in which the observed random variables are the steps of a symmetric random walk. Assuming continuously distributed step sizes, it describes the optimal stopping rules for the cases n = 2 and n = 3 in two versions of the problem: a "full information" version in which the actual steps of the random walk are disclosed to the decision maker; and a "partial information" version in which only the relative ranks of the positions taken by the random walk are observed. When n = 3, the optimal rule and expected rank depend on the distribution of the step sizes. The authors give sharp bounds for the optimal expected rank in the partial information version, and fairly sharp bounds in the full information version.

Salt-water acclimation of the estuarine crocodile Crocodylus porosus involves enhanced ion transport properties of the urodaeum and rectum (open access)

Salt-water acclimation of the estuarine crocodile Crocodylus porosus involves enhanced ion transport properties of the urodaeum and rectum

This article reports that in addition to the well-documented functional plasticity of the lingual salt glands, the middle of the three cloacal segments (i.e. the urodaeum) responds to increased ambient salinity to enhance solute-coupled water absorption in estuarine crocodiles (Crocodylus porosus).
