Rural residents are typically construed as being more conservative than urban residents. Is this true, or do rural residents carry unique interests from Republicans or conservatives? Using the 2020 ANES, we compare responses from 22 national issues by interacting urban and rural residency with Republican and Democrat identification. We find that issue preferences are partisan, not place-based: rural Democrats resemble their urban counterparts and urban Republicans resemble their rural counterparts, rather than rural areas specifically being more Republican. However, rural Democrats are more conservative than urban Democrats on issues relating to immigration, transgendered people in the military, and income inequality. These results point to partisan nationalization in issue stances, with exceptions, and that rural is not always Republican.

Politics and science have become increasingly intertwined. Salient scientific issues, such as climate change, evolution, and stem-cell research, become politicized, pitting partisans against one another. This creates a challenge of how to effectively communicate on such issues. Recent work emphasizes the need for tailored messages to specific groups. Here, we focus on whether generalized messages also can matter. We do so in the context of a highly polarized issue: extreme COVID-19 vaccine resistance. The results show that science-based, moral frame, and social norm messages move behavioral intentions, and do so by the same amount across the population (that is, homogeneous effects). Counter to common portrayals, the politicization of science does not preclude using broad messages that resonate with the entire population.

Gas-fluidized beds of flexible fibres, which have been rarely studied before, are investigated in this work using the coupled approach of the discrete element method and computational fluid dynamics. In the present numerical method, gas–fibre interaction is modelled by calculating the interaction force for each constituent element in the fibre, and the composition of the interaction forces on the constituent elements generates a resultant hydrodynamic force and a resultant hydrodynamic torque on the fibre. Pressure drops and fibre orientation results from the present simulations with various fibre aspect ratios are in good agreement with previous experimental and simulation results. Some novel results are obtained for the effects of fibre flexibility. Larger hydrodynamic forces on fibres (before the bed is fluidized) and smaller minimum fluidization velocities (MFVs) are observed for more flexible fibre beds due to the smaller porosities, while smaller hydrodynamic forces are obtained for the more flexible fibres when the beds are fluidized with significant fibre motion. By scaling the superficial gas velocity using the MFVs, the data of pressure drop can collapse onto the Ergun correlation for stiff fibres of various aspect ratios; however, the pressure drop curves deviate from the Ergun correlation for very flexible fibres, due to the significant fibre bed expansion before the MFV is reached. The fibre aspect ratio and flexibility both have an impact on the solids mixing rate, and it is found that the solids mixing rates are essentially determined by the ratio of the superficial gas velocity to MFV.

B vitamins involved in one-carbon metabolism have been implicated in the development of inflammation- and angiogenesis-related chronic diseases, such as colorectal cancer (CRC). Yet, the role of one-carbon metabolism in inflammation and angiogenesis among CRC patients remains unclear. The objective of this study was to investigate associations of components of one-carbon metabolism with inflammation and angiogenesis biomarkers among newly diagnosed CRC patients (n 238) in the prospective ColoCare Study, Heidelberg. We cross-sectionally analysed associations between twelve B vitamins and one-carbon metabolites and ten inflammation and angiogenesis biomarkers from pre-surgery serum samples using multivariable linear regression models. We further explored associations among novel biomarkers in these pathways with Spearman partial correlation analyses. We hypothesised that pyridoxal-5’-phosphate (PLP) is inversely associated with inflammatory biomarkers. We observed that PLP was inversely associated with C-reactive protein (CRP) (r –0·33, Plinear < 0·0001), serum amyloid A (SAA) (r –0·23, Plinear = 0·003), IL-6 (r –0·39, Plinear < 0·0001), IL-8 (r –0·20, Plinear = 0·02) and TNFα (r –0·12, Plinear = 0·045). Similar findings were observed for 5-methyl-tetrahydrofolate and CRP (r –0·14), SAA (r –0·14) and TNFα (r –0·15) among CRC patients. Folate catabolite acetyl-para-aminobenzoylglutamic acid (pABG) was positively correlated with IL-6 (r 0·27, Plinear < 0·0001), and pABG was positively correlated with IL-8 (r 0·21, Plinear < 0·0001), indicating higher folate utilisation during inflammation. Our data support the hypothesis of inverse associations between PLP and inflammatory biomarkers among CRC patients. A better understanding of the role and inter-relation of PLP and other one-carbon metabolites with inflammatory processes among colorectal carcinogenesis and prognosis could identify targets for future dietary guidance for CRC patients.

U60 ([UO2(O2)(OH)]60 60− in water) is a uranyl peroxide nanocluster with a fullerene topology and O h symmetry. U60 clusters can exist in crystalline solids or in liquids; however, little is known of their behavior at high pressures. We compressed the U60-bearing material: Li68K12(OH)20[UO2(O2)(OH)]60(H2O)310 ( $Fm\bar 3$ ; a = 37.884 Å) in a diamond anvil cell to determine its response to increasing pressure. Three length scales and corresponding structural features contribute to the compression response: uranyl peroxide bonds (<0.5 nm), isolated single nanoclusters (2.5 nm), and the long-range periodicity of nanoclusters within the solid (>3.7 nm). Li68K12(OH)20[UO2(O2)(OH)]60(H2O)310 transformed to a tetragonal structure below 2 GPa and irreversibly amorphized between 9.6 and 13 GPa. The bulk modulus of the tetragonal U60-bearing material was 25 ± 2 GPa. The pressure-induced amorphous phase contained intact U60 clusters, which were preserved beyond the loss of long-range periodicity. The persistence of U60 clusters at high pressure may have been enhanced by the interaction between U60 nanoclusters and the alcohol pressure medium. Once formed, U60 nanoclusters persist regardless of their associated long-range ordering—in crystals, amorphous solids, or solutions.

Against the background of population ageing and increasing cultural diversity in many Western countries, the study examined differences and similarities between Australian-born people and Chinese immigrants in their relationships with adult children. The specific research questions were: (a) are there differences between these groups in the nature of parent–child relationships; and (b) if there were differences, did these differences reflect the Confucian concept of filial piety among older Chinese immigrants. The solidarity–conflict model and the concept of ambivalence were used to quantify parent–child relationships. Data from 122 community-dwelling people aged 65 and over (60 Australian-born and 62 Chinese-born people) were collected using standardised interviews. There were significant differences between the two groups for all relationship dimensions except associative solidarity. Compared to Australian participants, Chinese participants were more likely to live with their children. However, when they did not live with their children, they lived further away. They were also more likely to receive, but less likely to provide, instrumental help. Finally, they reported higher levels of normative solidarity, conflict and ambivalence, and lower levels of affectual and consensual solidarity. The differences in solidarity dimensions persisted when socio-demographic variables were controlled for. The study revealed complex differences in the nature of older parent–child relationships between Australian-born people and Chinese immigrants. Some of these differences, such as more prevalent multigenerational living among older Chinese immigrants, likely reflect the strong influence of filial piety among this group. However, differences in other dimensions, such as lower levels of consensual solidarity, might be associated with the Chinese participants’ experience as immigrants. This study also highlights the usefulness of the solidarity–conflict model as a theoretical framework to understand the nature of parent–child relationships among older Chinese immigrants.

On January 12, 2010, a major earthquake in Haiti resulted in approximately 212 000 deaths, 300 000 injuries, and more than 1.2 million internally displaced people, making it the most devastating disaster in Haiti's recorded history. Six academic medical centers from the city of Chicago established an interinstitutional collaborative initiative, the Chicago Medical Response, in partnership with nongovernmental organizations (NGOs) in Haiti that provided a sustainable response, sending medical teams to Haiti on a weekly basis for several months. More than 475 medical volunteers were identified, of whom 158 were deployed to Haiti by April 1, 2010. This article presents the shared experiences, observations, and lessons learned by all of the participating institutions. Specifically, it describes the factors that provided the framework for the collaborative initiative, the communication networks that contributed to the ongoing response, the operational aspects of deploying successive medical teams, and the benefits to the institutions as well as to the NGOs and Haitian medical system, along with the challenges facing those institutions individually and collectively. Academic medical institutions can provide a major reservoir of highly qualified volunteer medical personnel that complement the needs of NGOs in disasters for a sustainable medical response. Support of such collaborative initiatives is required to ensure generalizability and sustainability.

The challenges associated with meeting 20nm technology requirements for better Cu CMP process uniformity and lower defectivity have been studied. Required improvements in uniformity were obtained through platen process optimization along with evaluation & selection of specific Cu slurries and pads and their performance reported. The principal factors influencing defect formation, including Cu barrier metallurgy, interconnect pattern density and process queue times were studied. Specific new post CMP clean chemistries were evaluated to assess their capability to suppress defect formation and their performance reported. The trade off between uniformity and defect suppression as a function slurry, pad and post Cu CMP clean chemistry is described.

In this poster we will present the photo-electrical effect of pristine and nitric acid treated graphene field effect transistors made by chemical vapor deposition (CVD). The results of the decreased electrical conductance and shift of Dirac point arise from the molecular photodesorption from graphene. When post treated with nitric acid the photodesorption efficiency was decrease from 52% to 21%, which was proposed to be caused by the passivation of oxygen-bearing functionalities to CVD graphene structural defects. This result provides a new strategy of stabilizing the electrical performance of CVD graphene which is promising candidate as highly conductively photoelectrical material.
