    A multidisciplinary team established the Davis County Create Healthy Gardens (CHG) program to improve access to fresh produce and help low-income residents gain skills to grow food and prepare nourishing meals. An evaluation of the program shows that participants had access to over 275 pounds of fresh produce, and most participants reported an increase in fruit and vegetable consumption. They also reported an increase in their knowledge in gardening and food preparation

    Effect of Sliding Contact on the Structure of Cu-X Nanolaminates

    Structural metallic nanolaminates (coatings consisting of alternating layers of different metals) are being explored for applications ranging from high strength foils to wear resistant coatings due to their relatively high hardness. This study seeks to explore how the nanolaminate structure evolves after deposition due to sliding contact. Using two-component Cu-Nb and Cu-Ag model systems (with 20 and 100 nm individual layers), the scratch and wear behavior was characterized using linear reciprocating deformation testing. It was shown that the damage due to sliding (depth of wear track) and coefficient of friction both increased with increasing layer thickness

    What do I want to feel? Emotion goals in childhood, adolescence, and adulthood

    Beliefs about emotion utility can influence context-sensitive emotion goals (i.e., desired emotional responses). Although key for emotion regulation, emotion goals have been overlooked in children and adolescents. In 2018–2019 results of Studies 1 and 2 showed that children (N = 192, Mage = 8.65, 47% girls, 96% White) were less motivated by and found anger less useful in confrontation than adolescents (N = 192, Mage = 12.96, 50% girls, 93% White) and adults (N = 195, Mage = 29.82, 51% women, 96% White). The link between emotion goals and beliefs about emotion utility was weaker in children. In 2021, Study 3 (N = 60, 8-year-olds, 47% girls, 90% White) ruled out expectations as a possible explanation for the previous findings. Context-sensitive utility of emotions may be acquired during development

    A Census of Star-Forming Galaxies in the z~9-10 Universe based on HST+Spitzer Observations Over 19 CLASH clusters: Three Candidate z~9-10 Galaxies and Improved Constraints on the Star Formation Rate Density at z~9

    We utilise a two-color Lyman-Break selection criterion to search for z~9-10 galaxies over the first 19 clusters in the CLASH program. A systematic search yields three z~9-10 candidates. While we have already reported the most robust of these candidates, MACS1149-JD, two additional z~9 candidates are also found and have H_{160}-band magnitudes of ~26.2-26.9. A careful assessment of various sources of contamination suggests <~1 contaminants for our z~9-10 selection. To determine the implications of these search results for the LF and SFR density at z~9, we introduce a new differential approach to deriving these quantities in lensing fields. Our procedure is to derive the evolution by comparing the number of z~9-10 galaxy candidates found in CLASH with the number of galaxies in a slightly lower redshift sample (after correcting for the differences in selection volumes), here taken to be z~8. This procedure takes advantage of the fact that the relative volumes available for the z~8 and z~9-10 selections behind lensing clusters are not greatly dependent on the details of the lensing models. We find that the normalization of the UV LF at z~9 is just 0.28_{-0.20}^{+0.39}\times that at z~8, ~1.4_{-0.8}^{+3.0}x lower than extrapolating z~4-8 LF results. While consistent with the evolution in the UV LF seen at z~4-8, these results marginally favor a more rapid evolution at z>8. Compared to similar evolutionary findings from the HUDF, our result is less insensitive to large-scale structure uncertainties, given our many independent sightlines on the high-redshift universe.Comment: 22 pages, 11 figures, 5 tables, accepted for publication in the Astrophysical Journal, updated to include the much deeper Spitzer/IRAC observations over our three z~9-10 candidate

    La grande vari&eacute;t&eacute; de formules propos&eacute;es pour le calcul des probabilit&eacute;s d&rsquo;exclusion de filiation erron&eacute;e est vraiment d&eacute;concertante. Le pr&eacute;sent travail essaie de donner une formule g&eacute;n&eacute;rale en consid&eacute;rant tous les cas possibles. Le g&eacute;notype du parent non contest&eacute; peut ne pas &ecirc;tre connu. En effet, dans certaines &eacute;tudes d&rsquo;exclusion du p&egrave;re, aucune information n&rsquo;est disponible en ce qui concerne le g&eacute;notype de la m&egrave;re. Dans ces cas, l&rsquo;augmentation du nombre de marqueurs utilis&eacute;s peut compenser ce manque d&rsquo;information. Cependant, pour que la connaissance du g&eacute;notype de la m&egrave;re soit utile, il faut que l&rsquo;individu dont la filiation est contest&eacute;e soit h&eacute;t&eacute;rozygote et que son g&eacute;notype soit diff&eacute;rent de celui de sa m&egrave;re. Par ailleurs, l&rsquo;absence d&rsquo;&eacute;quilibre de Hardy-Weinberg ou de liaison, pour les marqueurs utilis&eacute;s pour la v&eacute;rification de la filiation, ne semble pas avoir une solution simple et claire

    Association Between Urinary Markers of Nucleic Acid Oxidation and Mortality in Type 2 Diabetes:A population-based cohort study

    Get PDF
    OBJECTIVE: We recently showed that RNA oxidation, estimated by urinary excretion of 8-oxo-7,8-dihydroguanosine (8-oxoGuo), independently predicted mortality in a cohort of 1,381 treatment-naive patients with newly diagnosed type 2 diabetes. In the present investigation, we analyzed urine collected 6 years after the diagnosis to assess the association between urinary markers of nucleic acid oxidation and mortality in patients with established and treated diabetes. RESEARCH DESIGN AND METHODS: We used data from the 970 patients who attended the screening for diabetes complications 6 years after the diagnosis. Cox proportional hazards regression was used to examine the relationship between urinary markers of DNA oxidation (8-oxo-7,8-dihydro-2′-deoxyguanosine [8-oxodG] [n = 938]) and RNA oxidation (8-oxoGuo [n = 936]) and mortality. RESULTS: During a median of 9.8 years of follow-up, 654 patients died. Urinary 8-oxoGuo assessed 6 years after the diagnosis was significantly associated with mortality. The multivariate-adjusted hazard ratios for all-cause and diabetes-related mortality of patients with 8-oxoGuo levels in the highest quartile compared with those in the lowest quartile were 1.86 (95% CI 1.34–2.58) and 1.72 (1.11–2.66), respectively. Conversely, 8-oxodG was not associated with mortality. In addition, we found an association between changes in 8-oxoGuo from diagnosis to 6-year follow-up and mortality, with increased risk in patients with an increase and decreased risk in patients with a decrease in 8-oxoGuo. CONCLUSIONS: The RNA oxidation marker 8-oxoGuo is an independent predictor of mortality in patients with established and treated type 2 diabetes, and changes in 8-oxoGuo during the first 6 years after diagnosis are associated with mortality
