Unconventional strong pinning in the low temperature phase of U_.9725Th_.0275Be_13

We investigated low field vortex dynamics in a single crystal of U_.9725Th_.0275Be_13. We found a sharp transition in the vortex creep rate at the lower transition temperature T_c2, coincident with the second jump in the specific heat. In the high-temperature phase, rather strong creep rates are observed. In the low temperature phase, the rates drop to undetectabely low levels. This behaviour indicates that a very strong pinning mechanism is present in the low temperature phase of U_.9725Th_.0275Be_13, which could be explained by the existence of domain walls, separating discreetly degenerate states of a superconductor, that can sustain fractional vortices and thus act as very strong pinning centers.Comment: 2 pages, 2 figures, accepted in PhysicaB, LT2

Revising the oral comprehensive exam in the UHM Marine Biology Graduate Program

The Marine Biology Graduate Program has established an ad-hoc committee to review existing protocols of the comprehensive exam and is collating the most effective elements and best practices from each of academic units across the program. This committee will make recommendations to the MBGP faculty at large for discussion, consideration, and ultimately implementation

Marine Bioinvasions and Climate Change

BACKGROUND Invasive species are second only to habitat destruction as the greatest cause of species endangerment and global biodiversity loss. Invasive species can cause severe and permanent damage to the ecosystems they invade. Consequences of invasion include competition with or predation upon native species, hybridization, carrying or supporting harmful pathogens and parasites that may affect wildlife and human health, disturbing ecosystem function through alteration of food webs and nutrient recycling rates, acting as ecosystem engineers and altering habitat structure, and degradation of the aesthetic quality of our natural resources. In many cases we may not fully know the native animals and plants in an area. For example, Aureophycus aleuticus, a large kelp was just described with similar discoveries of new taxa in many other latitudes. Invasive species have the potential to permanently change ecosystems before we fully understand the native communities. Recent studies suggest that invasive species share similar traits that allow for easier establishment in habitats that become disrupted by climate change. The examples below highlight some of the ongoing and expected changes to marine ecosystems that may occur as a result of the interactions between global climate change and biological invasion

Biomechanical Effects of Obesity on Balance

International Journal of Exercise Science 5(4) : 301-320, 2012. The objective of this review was to analyze the current literature related to the effects of obesity on balance. These effects were observed during conditions of static balance, perturbed balance and dynamic balance during gait. The literature review included studies focused on the biomechanical effects of obesity, the relationship between weight loss and balance, and the relative efficacy of weight loss as a balance intervention. The older adult population, which faces increased risk of falls and related injuries, was highlighted where targeted research was available. The existing literature provides evidence for a strong link between obesity and balance impairments. This meta-analysis supports the efficacy of weight loss as an intervention to improve balance in the obese. Additional investigations are needed to confirm the reliability of relationships noted in this review paper, and to explore the potential of weight loss in simple and combined interventions. Future research should also determine whether efficacy differs among populations

Food Security: Let them Eat Information

Insufficient information to predict famine was widely seen to be a central reason for the failure of national governments and the international donor community to prevent famines in Africa in the mid 1980s. Since then, there have been substantial improvements in the development of purpose-built information systems to predict famine. Many new famine early warning systems (EWS) have been set up, but the goal of famine prevention remains elusive. At least in the Sahel and Horn of Africa, the information now provided is not being used adequately to trigger timely and appropriate response.European Research Council (ERC

CAPAbility: Comparison of the JOURNEY II Bi-Cruciate Stabilised and GENESIS II total knee arthroplasty in performance and functional ability: protocol of a randomised controlled trial

Background: Osteoarthritis of the knee is a common condition that is expected to rise in the next two decades leading to an associated increase in total knee replacement (TKR) surgery. Although there is little debate regarding the safety and efficacy of modern TKR, up to 20% of patients report poor functional outcomes following surgery. This study will investigate the functional outcome of two TKRs; the JOURNEY II Bi-Cruciate Stabilised knee arthroplasty, a newer knee prosthesis designed to provide guided motion and improve knee kinematics by more closely approximating a normal knee, and the GENESIS II, a proven existing design. Aim: To compare the change in Patient-reported Outcome Measures (PROMs) scores of the JOURNEY II BCS and the GENESIS II from pre-operation to 6 months post operation. Methods: CAPAbility is a pragmatic, blinded, two-arm parallel, randomised controlled trial recruiting patients with primary osteoarthritis due to have unilateral TKR surgery across two UK hospitals. Eligible participants (n = 80) will be randomly allocated to receive either the JOURNEY II or the GENESIS II BCS knee prosthesis. Baseline measures will be taken prior to surgery. Patients will be followed at 1 week, 6 to 8 weeks and 6 months post-operatively. The primary outcome is the Oxford Knee Score (OKS) at 6 months post-operatively. Secondary outcomes include: Other PROMs, biomechanical, radiological (computerised tomography, (CT)), clinical efficacy and safety outcomes. An embedded qualitative study will also investigate patients' perspectives via interview pre and post surgery on variables known to affect the outcome of TKR surgery. A sub-sample (n = 30) will have additional in-depth interviews to explore the themes identified. The surgeons' perspectives on the operation will be investigated by a group interview after all participants have undergone surgery. Discussion: This trial will evaluate two generations of TKR using PROMS, kinematic and radiological analyses and qualitative outcomes from the patient perspective
