This paper reports the design and development of the Diceman Query Application. the paper discusses the implications of the interface on the underlying search engine

Salient selves in uncertain futures

We examined possible selves during three distinct periods of uncertainty. Cancer survivors (Study 1a) and survivors’ romantic partners (Study 1b) rated the salience of possible selves in which the cancer did (negative possible self; NPS) and did not (positive possible self; PPS) return. Study 2 mapped PPS and NPS salience throughout the four-month wait for bar exam results. Study 3 experimentally primed possible selves among participants awaiting medical test results. PPS salience correlated positively, and NPS negatively, with indicators of health and well-being, and inducing focus on one’s NPS led to greater negative emotion and worry compared to a PPS induction, but not less positive emotion. These results illustrate the well-being implications of possible selves during periods of uncertainty

Model system studies with a phase separated membrane bioreactor

The operation and evaluation of a bioreactor designed for high intensity oxygen transfer in a microgravity environment is described. The reactor itself consists of a zero headspace liquid phase separated from the air supply by a long length of silicone rubber tubing through which the oxygen diffuses in and the carbon dioxide diffuses out. Mass transfer studies show that the oxygen is film diffusion controlled both externally and internally to the tubing and not by diffusion across the tube walls. Methods of upgrading the design to eliminate these resistances are proposed. Cell growth was obtained in the fermenter using Saccharomyces cerevisiae showing that this concept is capable of sustaining cell growth in the terrestial simulation

Morphology and Redshifts of Extremely Red Galaxies in the GOODS/CDFS deep ISAAC field

We present the photometric redshift distribution of a sample of 198 Extremely Red Galaxies (ERGs) with Ks3.92 (Vega), selected by Roche et al. in 50.4 sq. arcmin of the Chandra Deep Field South (CDFS). The sample has been obtained using ISAAC-VLT and ACS-HST GOODS public data. We also show the results of a morphological study of the 72 brightest ERGs in the z band (z<25, AB).Comment: 2 pages, 2 figures.

Towards high quality text entry on smartwatches

Smartwatches now provide users with access to many applications on smartphones direct from their wrists, without the need to touch their smartphone. While applications such as email, messaging, calendar and social networking provide views on the watch, there is normally no text entry method so users cannot reply on the same device. Here we introduce requirements for smartwatch text entry, an optimised alphabetic layout and present a prototype implementation together with preliminary user feedback. While raising some problems, the feedback gives indicates that reasonable quality and speed is achievable on a smartwatch and encourages our future work

Design concepts for bioreactors in space

Microbial food sources are becoming viable and more efficient alternatives to conventional food sources especially in the context of Closed Ecological Life Support Systems (CELSS) in space habitats. Since bioreactor designs for terrestrial operation will not readily apply to conditions of microgravity, there is an urgent need to learn about the differences. These differences cannot be easily estimated due to the complex nature of the mass transport and mixing mechanisms in fermenters. Therefore, a systematic and expeditious experimental program must be undertaken to obtain the engineering data necessary to lay down the foundations of designing bioreactors for microgravity. Two bioreactor design concepts presented represent two dissimilar approaches to grappling with the absence of gravity in space habitats and deserve to be tested for adoption as important components of the life support function aboard spacecrafts, space stations and other extra-terrestrial habitats
