Measurement of the b-hadron production cross section using decays to μ-D0X final states in pp̄ collisions at s=1.96TeV

Abstract: We report a measurement of the production cross section for b hadrons in p{bar p} collisions at {radical}s = 1.96 TeV. Using a data sample derived from an integrated luminosity 83 pb{sup -1} collected with the upgraded Collider Detector (CDF II) at the Fermilab Tevatron, we analyze b hadrons, H{sub b}, partially reconstructed in the semileptonic decay mode H{sub b} {yields} {mu}{sup -} D{sup 0} X. Our measurement of the inclusive production cross section for b hadrons with transverse momentum p{sub T} > 9 GeV/c and rapidity |y| < 0.6 is {sigma} = 1.30 {micro}b {+-} 0.05 {micro}b(stat) {+-} 0.14 {micro}b(syst) {+-} 0.07 {micro}b({Beta}), where the uncertainties are statistical, systematic, and from branching fractions respectively. The differential cross sections d{sigma}/d{sub T}T are found to be in good agreement with recent measurements of the H{sub b} cross section and well described by fixed-order next-to-leading logarithm predictions.

The Emergence and Development of the Politics of Recognition of Cultural Diversity and Indigenous Peoples' Rights in Mexico: Chiapas and Oaxaca in Comparative Perspective

Abstract: In this article I attempt to explain the differentiated development of the politics of recognition – that is the process of formal recognition of cultural diversity and indigenous peoples' rights – in Mexico, particularly in the states of Oaxaca and Chiapas. I follow an explanatory framework that proposes that the recognition agenda emerges in the context of armed conflict and/or legitimacy and governability crises, and evolves successfully when indigenous actors get access to the decision-making process and form alliances with key political actors. I find that government legitimacy has eroded in both states, and that governability has been severely threatened in Oaxaca and disturbed by armed conflict in Chiapas. However, only in the former have indigenous actors influenced the decision-making process and made alliances with the key decision-makers. This latter finding – fundamental within the explanatory framework followed – begs a further question – why was an alliance between the indigenous and the government elite possible in Oaxaca but not in Chiapas? I go beyond the original explanatory framework and identify a series of structural, contextual and agent-related factors that account for the uneven development of the politics of recognition in each state.

Acrylamide Polymer Double-Network Hydrogels: Candidate Cartilage Repair Materials with Cartilage-Like Dynamic Stiffness and Attractive Surgery- Related Attachment Mechanics

Abstract: Background:In focal repair of joint cartilage and meniscus, initial stiffness and strength of repairs are generally much less than surrounding tissue. This increases early failure potential. Secure...
