Oviposition Decisions by Indianmeal Moth

The Indianmeal moth, Plodia interpunctella,is a pest in the United States of stored grains. The larvae feed on grains, grain products, dried fruits, nuts, cereals and a variety of processed food products. Indianmeal moths can detect where other Indianmeal moths have laid eggs but it is unknown if they know where other species have been and laid eggs. So, does the colonization of flour by other species affect where an Indianmeal moth will lay her eggs? Our results showed there was no preference for colonized or uncolonized flour by the moths. The average number of eggs laid in both patches of flour was even. This data shows us that the moths do not have a preference where they lay their eggs, potentially increasing competition among species in food patches

Top asymmetry and the search for a light hadronic resonance in association with single top

The exchange of a light $t$-channel flavor-changing gauge boson, \Vp, with mass $\sim m_{top}$ remains a leading explanation for the anomalous forward backward asymmetry in top quark production at the Tevatron. Unlike other ideas, including heavier $t$-channel mediators, the light \Vp model is not easily seen in the \mtt distribution. We advocate a more promising strategy. While current analyses at hadron colliders may not be sensitive, we propose searching for a $jj$ resonance in association with single top that may allow discovery in existing data. Deviations in the lepton charge asymmetry in this sample should also be present.Comment: 5 pages, 2 figur

Top quark asymmetry and dijet resonances

CDF recently reported an anomaly in the $m_{jj}$ distribution of dijet events produced in association with a $W$ boson. If this anomaly is associated with a new flavor conserving vector resonance, $V$, one might have expected to observe effects in the analogous $m_{jj}$ distribution produced in association with a $\gamma$. No such excess is observed. A single $u-t-V$ flavor changing coupling, however, can contribute to the $m_{jj}$ anomaly while being consistent with other resonance searches. Furthermore, it gives a potential explanation of the observed forward-backward asymmetry in top quark production.Comment: 4 pages, 1 figur

Efficacy of Assistive Devices Produced with Additive Manufacturing

Despite the frequency of musculoskeletal injuries such as sprains, broken bones and torn ligaments1, treatment options are often costly, time-consuming and ill-fitted.2,3 Additive manufacturing (“3D-printing) allows for the production of highly-customized and inexpensive assistive devices4, which suggests potential efficacy in the prescription of splints and casts for musculoskeletal injury.3 In the present study, a parametric, customizable splint/cast was created using a computer-aided design (CAD) package (Fusion 360, Autodesk, San Rafael, CA, USA) and produced with low-cost, desktop 3D printing (Ultimaker 2+ Extended, Ultimaker, Geldermalsen, Netherlands). Fitting of the devices was performed on five healthy subjects (mean age 23.6 +/- 1.51 years, n = 4 male), and function was assessed by a certified clinician in comparison to commonly prescribed devices. The function of the custom, 3D-printed assistive devices was found to be similar to that of standard wrist splints and short arm casts, with the added benefits of reduced weight, enhanced water resistance and better ventilation. These results suggest that additive manufacturing may be promising in the treatment of common musculoskeletal injuries.
