Realization of a Resonant Fermi Gas with a Large Effective Range

We have measured the interaction energy and three-body recombination rate for a two-component Fermi gas near a narrow Feshbach resonance and found both to be strongly energy dependent. Even for deBroglie wavelengths greatly exceeding the van der Waals length scale, the behavior of the interaction energy as a function of temperature cannot be described by atoms interacting via a contact potential. Rather, energy-dependent corrections beyond the scattering length approximation are required, indicating a resonance with an anomalously large effective range. For fields where the molecular state is above threshold, the rate of three-body recombination is enhanced by a sharp, two-body resonance arising from the closed-channel molecular state which can be magnetically tuned through the continuum. This narrow resonance can be used to study strongly correlated Fermi gases that simultaneously have a sizeable effective range and a large scattering length.Comment: to appear in Phys. Rev. Let

Three-body recombination in a three-state Fermi gas with widely tunable interactions

We investigate the stability of a three spin state mixture of ultracold fermionic $^6$Li atoms over a range of magnetic fields encompassing three Feshbach resonances. For most field values, we attribute decay of the atomic population to three-body processes involving one atom from each spin state and find that the three-body loss coefficient varies by over four orders of magnitude. We observe high stability when at least two of the three scattering lengths are small, rapid loss near the Feshbach resonances, and two unexpected resonant loss features. At our highest fields, where all pairwise scattering lengths are approaching $a_t = -2140 a_0$, we measure a three-body loss coefficient $L_3 \simeq 5\times 10^{-22} \mathrm{cm}^6/\mathrm{s}$ and a trend toward lower decay rates for higher fields indicating that future studies of color superfluidity and trion formation in a SU(3) symmetric Fermi gas may be feasible

Mending the Gaps: An Exercise in Identifying and Understanding Diverse and Multicultural Team Faultlines

The Faultlines Exercise, an experiential activity, introduces students to concepts of diversity attributes (surface and deep levels), social identity, and team faultlines. Through individual reflection and team discussion, students apply these concepts to their own diverse multicultural class teams with the goals of (a) preventing negative outcomes that may develop from faultlines and (b) improving team performance. Plenary class discussions reinforce key learning points that can be applied to teamwork throughout the course. Students in both face-to-face and online classes report that the exercise helps improve team performance and helps to identify and resolve problems. Instructions for facilitating classroom discussion and student handouts are provided, as are suggestions for adapting the exercise to other constructs

A Quality System Database

A quality system database (QSD), and software to administer the database, were developed to support recording of administrative nonconformance activities that involve requirements for documentation of corrective and/or preventive actions, which can include ISO 9000 internal quality audits and customer complaints

Relation between high-sensitivity C-reactive protein and cardiovascular and renal markers in a middle-income country in the African region.

BACKGROUND: High-sensitivity C-reactive protein (hs-CRP) is associated with several cardiovascular risk factors (CVRF) and with renal function markers. However, these associations have not been examined in populations in the African region. We analyzed the distribution of hs-CRP and the relationship with a broad set of CVRF, renal markers and carotid intima-media thickness (IMT), in the Seychelles (African region). METHODS: We conducted a survey in the population aged 25-64years (n=1255, participation rate: 80.2%). Analyses were restricted to persons of predominantly African descent (n=1011). RESULTS: Mean and median hs-CRP serum concentrations (mg/l) were 3.1 (SD 7.6) and 1.4 (IQR 0.7-2.9) in men and 4.5 (SD 6.7) and 2.2 (IQR 1.0-5.4) in women (p<0.001 for difference between men and women). hs-CRP was significantly associated with several conventional CVRF, and particularly strongly with markers of adiposity. With regards to renal markers, hs-CRP was strongly associated with cystatin C and with microalbuminuria but not with creatinine. hs-CRP was not associated with IMT. CONCLUSIONS: Serum concentration of hs-CRP was significantly associated with sex, several CVRF and selected renal function markers, which extends similar findings in Europe and in North America to a population in the African region. These findings can contribute to guide recommendations for the use of hs-CRP in clinical practice in the region

Health literacy and its association with adherence in pediatric liver transplant recipients and their parents

ObjectiveNon- adherence to pediatric regimens is a common concern. Low health literacy is correlated with poor outcomes in adults but is understudied in pediatrics. The current project aimed to determine the relationship between health literacy, adherence, and outcomes in pediatric liver transplant recipients. Hypotheses included a) parent and patient health literacy would be positively correlated; and b) low patient and/or parent health literacy would be negatively correlated with adherence and health outcomes.Patients and MethodsEligible participants were recruited during routine follow- up visits in a pediatric liver transplant clinic. Parents and patients (>13 years old) completed 2 measures of health literacy. Patients - ¥18 years completed health literacy measures without corresponding parent surveys. Adherence variables and health outcomes were obtained from medical records.ResultsSeventy- nine patients across two sites completed the study. Variance in classification of health literacy between measures was observed; however, most parents (82%- 100%) scored within an - adequate literacy- range. More adolescents scored in lower health literacy ranges relative to the parents. Markers of SES were positively correlated with health literacy. Parent health literacy was negatively associated with biopsy- proven rejection episodes and the number of hospitalizations; however, it was not associated with measures of tacrolimus adherence. There were no relationships observed between parent and adolescent health literacy.ConclusionsHealth literacy is an important consideration in managing patient care; however, available measures demonstrate variability in capturing the skills of patients. Effective communication strategies may ameliorate admittedly small, but negative, impacts of limited health literacy on outcomes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/156215/2/petr13726_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/156215/1/petr13726.pd
