Quantum register based on coupled electron spins in a room-temperature solid.

Abstract: Nitrogen–vacancy centres in diamond have emerged as a promising platform for quantum information processing at room temperature. Now, coherent coupling between two electron spins separated by almost 10 nm has been demonstrated. At this distance, the spins can be addressed individually, which might enable the construction of a network of connected quantum registers.

Meta-Analysis of the Reasoned Action Approach (RAA) to Understanding Health Behaviors.

Abstract: Background Reasoned action approach (RAA) includes subcomponents of attitude (experiential/instrumental), perceived norm (injunctive/descriptive), and perceived behavioral control (capacity/autonomy) to predict intention and behavior

Fundamental trade-offs generating the worldwide leaf economics spectrum

Abstract: Recent work has identified a worldwide ''economic'' spectrum of correlated leaf traits that affects global patterns of nutrient cycling and primary productivity and that is used to calibrate vegetation-climate models. The correlation patterns are displayed by species from the arctic to the tropics and are largely independent of growth form or phy- logeny. This generality suggests that unidentified fundamental constraints control the return of photosynthates on investments of nutrients and dry mass in leaves. Using novel graph theoretic methods and structural equation modeling, we show that the relationships among these variables can best be explained by assuming (1) a necessary trade-off between al- location to structural tissues versus liquid phase processes and (2) an evolutionary trade- off between leaf photosynthetic rates, construction costs, and leaf longevity.

The state, gender, and sexual politics

Abstract: The classic feminist slogan "the personal is political" states a basic feature of feminist and gay politics, a link between personal experience and power relations. In many cases the power relations are immediately present in personal life, in matters conventionally thought "private": housework, homophobic jokes, office sexuality, child rearing. Yet there is also a highly "public" dimension of these politics. During the 1970s, Western feminisms made open and substantial demands on the state in every country where a significant mobilization of women occurred. So did gay liberation movements, where they developed. The list of reforms sought includes the decriminalization of abortion in France, a constitutional guarantee of equal rights for women in the USA, rape law reform in Australia, decriminalization of homosexuality in many countries; not to mention expanded state provision of child care, nonsexist education, protection against sexual violence, equal employment opportunity, and anti-discrimination measures. By the early 1980s a women's peace movement had added disarmament and feminist environmentalists had added environmental protection neither conventionally thought of as gender politics but both now argued in gender terms.'

Structural Basis of Light Harvesting by Carotenoids: Peridinin-Chlorophyll-Protein from Amphidinium carterae

Abstract: Peridinin-chlorophyll-protein, a water-soluble light-harvesting complex that has a blue-green absorbing carotenoid as its main pigment, is present in most photosynthetic dinoflagellates. Its high-resolution (2.0 angstrom) x-ray structure reveals a noncrystallographic trimer in which each polypeptide contains an unusual jellyroll fold of the α-helical amino- and carboxyl-terminal domains. These domains constitute a scaffold with pseudo-twofold symmetry surrounding a hydrophobic cavity filled by two lipid, eight peridinin, and two chlorophyll a molecules. The structural basis for efficient excitonic energy transfer from peridinin to chlorophyll is found in the clustering of peridinins around the chlorophylls at van der Waals distances.
