Controlled Ecological Life Support System: Use of Higher Plants

Results of two workshops concerning the use of higher plants in Controlled Ecological Life Support Systems (CELSS) are summarized. Criteria for plant selection were identified from these categories: food production, nutrition, oxygen production and carbon dioxide utilization, water recycling, waste recycling, and other morphological and physiological considerations. Types of plant species suitable for use in CELSS, growing procedures, and research priorities were recommended. Also included are productivity values for selected plant species

How Diet Choices and Weight Change Person Perception

Previous studies have explored how overweight targets are perceived and the physical and psychological characteristics commonly used to describe them. The current study experimentally investigated the relationship between a target?s weight and his or her diet choices, and the characteristics used to describe him or her. The participants were exposed to one of four situations (overweight/unhealthy diet, overweight/healthy diet, average-weight/unhealthy diet, average-weight/ healthy diet) where they were shown a picture and a short description of the target. It is likely that overweight and unhealthy diet targets were rated lower on questions pertaining to physical health. Regardless of weight, healthy diet targets will likely be rated higher than unhealthy diet targets for positive psychological attributes. Overall, overweight/unhealthy diet targets will likely be rated the lowest in all three categories (positive psychological attributes, negative psychological attributes, and physical attributes)

How Diet Choices and Weight Change Person Perception

Previous studies have explored the negative perceptions of overweight targets along with the specific physical and psychological characteristics commonly used to describe them. The current study extends this literature by experimentally investigating the effect that both weight and diet choices have on the characteristics attributed to an individual. Participants were exposed to one of four scenarios that involved exposure to an image (overweight or average) and a short description of the target with the diet manipulation (healthy or unhealthy) embedded. As expected, overweight targets with unhealthy diets were rated lowest on perceptions of physical health and independent of weight, targets with healthy diets were rated higher on positive psychological attributes. Overall, overweight targets with unhealthy diets were rated the lowest in all three categories (positive psychological attributes, negative psychological attributes, and physical attributes)

Post-Conviction Access to DNA Testing: Why Massachusetts’s 278A Statute Should Be the Model for the Future

With the recent rise of the Innocence Movement, many traditional police tools for evaluating forensic evidence have been called into question. Increasingly, science has proven that certain outdated forensic analyses are unreliable or invalid, shedding light on how these faulty analyses have contributed to numerous unjust convictions of innocent people. Deoxyribonucleic acid (DNA) technology, a subset of forensic analysis, has performed the counterpoint to this trend by exonerating many wrongfully convicted individuals. Access to DNA testing, however, is inconsistent from state to state. Massachusetts’s new 278A motion is a strong model for the correct implementation of a statute providing post-conviction access to DNA testing. States such as Pennsylvania, which has a plethora of barriers to post-conviction relief through DNA testing, should look to Massachusetts’s 278A statute as an example on which to base updated post-conviction statutes in order to provide the necessary justice to those who have been wrongfully convicted

Stiffnesses by (TtN) ensemble molecular dynamics

Calculation of elastic constants requires initializing a lattice of atoms, an h matrix defining the computational cell boundaries, and the parameters defining the interatomic potentials, then numerically integrating the equations of motion for the atoms and the computational cell boundaries, calculating strains and stresses at each timestep, and updating at each timestep the average quantities required for calculation of fluctuations. Enforcements of the DYNAMO FORTRAN code included addition of documentation, improved memory management and data flow, and enabling use of several interatomic potentials. Documentation included headers for each subroutine, which document the parameters input to the routine, algorithms employed, and output

International Lighting in Controlled Environments Workshop

Lighting is a central and critical aspect of control in environmental research for plant research and is gaining recognition as a significant factor to control carefully for animal and human research. Thus this workshop was convened to reevaluate the technology that is available today and to work toward developing guidelines for the most effective use of lighting in controlled environments with emphasis on lighting for plants but also to initiate interest in the development of improved guidelines for human and animal research

GEM: graphical explorer for MPI programs

technical reportFormal dynamic verification can complement MPI program testing by detecting hard-to-find concurrency bugs. In previous work, we described our dynamic verifier called ISP that can parsimoniously search the execution space of an MPI program while detecting important classes of bugs. One major limitation of ISP, when used by itself, is the lack of a powerful and widely usable graphical front-end. We present a new tool called Graphical Explorer of Message Passing (GEM) that overcomes this limitation. GEM is a plug-in architecture that greatly enhances the usability of ISP, and may help bring ISP within reach of a wide array of programmers, given its imminent release as part of the Eclipse Foundation Parallel Tools Platform (PTP) Version 3.0. This paper describes GEM?s features, its architecture, and usage experience summary of the ISP/GEM combination. Recently, we applied this combination on a widely used parallel hypergraph partitioner. Even with modest amounts of computational resources, the ISP/GEM combination finished quickly, and intuitively displayed a previously unknown resource leak in this code-base
