Summary of the Structure Functions and Low-x working group
We report a summary of the structure function working group which covers a
wide range of the recent results from HERA, Tevatron, RHIC, and JLab
experiments, and many theoretical issues from low x to high x.Comment: 20 pages, presented at 13th International Workshop on Deep Inelastic

Up Sector of Minimal Flavor Violation: Top Quark Properties and Direct D meson CP violation
Minimal Flavor Violation in the up-type quark sector leads to particularly
interesting phenomenology due to the interplay of flavor physics in the charm
sector and collider physics from flavor changing processes in the top sector.
We study the most general operators that can affect top quark properties and
meson decays in this scenario, concentrating on two CP violating operators
for detailed studies. The consequences of these effective operators on charm
and top flavor changing processes are generically small, but can be enhanced if
there exists a light flavor mediator that is a Standard Model gauge singlet
scalar and transforms under the flavor symmetry group. This flavor mediator can
satisfy the current experimental bounds with a mass as low as tens of GeV and
explain observed -meson direct CP violation. Additionally, the model
predicts a non-trivial branching fraction for a top quark decay that would
mimic a dijet resonance.Comment: 27 pages, 7 figure
Functionality and design influence on fitness fashion
The growing debate between design and functionality dominates within the sportswear industry. Consumers purchase sportswear indirectly due to personal and social intrinsic attributes. Sportswear should be functional, comfortable and safe, developed in line with the performance needs of a person. Hence this study aims to explore the intrinsic factors of consumers purchase intention towards fitness fashion. The conceptual model which is an integration of Social Cognition and Enclothed Cognition theories was analysed using double mediation and reveals that personal
and social factors affect perceived importance on functionality and design. While most research claims extrinsic values as main factors of purchase, other perceptions of consumers could come into play which would be beneficial for sportswear brands to identify with and leverage on. The results of this research can assist companies to gain prominence, leveraging on the growing
popularity of active lifestyles by designing clothing that match those perceptions
Neural stem cells and the regulation of adult neurogenesis
Presumably, the 'hard-wired' neuronal circuitry of the adult brain dissuades addition of new neurons, which could potentially disrupt existing circuits. This is borne out by the fact that, in general, new neurons are not produced in the mature brain. However, recent studies have established that the adult brain does maintain discrete regions of neurogenesis from which new neurons migrate and become incorporated into the functional circuitry of the brain. These neurogenic zones appear to be vestiges of the original developmental program that initiates brain formation. The largest of these germinal regions in the adult brain is the subventricular zone (SVZ), which lines the lateral walls of the lateral ventricles. Neural stem cells produce neuroblasts that migrate from the SVZ along a discrete pathway, the rostral migratory stream, into the olfactory bulb where they form mature neurons involved in the sense of smell. The subgranular layer (SGL) of the hippocampal dentate gyrus is another neurogenic region; new SGL neurons migrate only a short distance and differentiate into hippocampal granule cells. Here, we discuss the surprising finding of neural stem cells in the adult brain and the molecular mechanisms that regulate adult neurogenesis
Stock Assessment of Ballot's saucer scallop (Ylistrum balloti) in Queensland
This assessment estimates the status of saucer scallops in the main fishing grounds of the Queensland Southern Inshore fishery. The stock assessment data inputs included total harvests, standardised catch rates and fishery independent density estimates.
Analyses suggested that spawning biomass in 2019 fell to around 17 per cent of the unfished level. The report presents recommendations on fishing effort levels to begin rebuilding the stock to levels consistent with 40 per cent of unfished biomass
EXOGEN Ultrasound Bone Healing System for Long Bone Fractures with Non-Union or Delayed Healing: A NICE Medical Technology Guidance
A routine part of the process for developing National Institute for Health and Care Excellence (NICE) medical technologies guidance is a submission of clinical and economic evidence by the technology manufacturer. The Birmingham and Brunel Consortium External Assessment Centre (EAC; a consortium of the University of Birmingham and Brunel University) independently appraised the submission on the EXOGEN bone healing system for long bone fractures with non-union or delayed healing. This article is an overview of the original evidence submitted, the EAC’s findings, and the final NICE guidance issued
Services and Staffing Practices within Academic Libraries Serving College of Osteopathic Medicine Programs: A Mixed Methods Study
This study provides a systematic comparison of services and staffing within academic health sciences libraries serving College of Osteopathic Medicine programs in the U.S. Library directors, not only those affiliated with new medical schools, but also with long- standing, and more traditional schools, can use this data to make a case for new resources, services, or staffing. In addition, medical school administrators may find opportunities in this study’s results for more productive collaborations with the library, in areas such as curriculum-integrated instruction, research development, and scholarly publishing. Finally, leaders within developing medical schools will become better informed about current library services being provided, and staffing trends, in order to plan for an appropriate budget and staffing for their future health sciences libraries
