Magnetic field sensing based on phase Ramsey interferometry with Bose condensed 87Rb atomic gases
Shenzhen Daxue xuebao. Ligong banMagnetic field sensing utilizing Bose-condensed atomic gases can achieve both high sensitivity and spatial resolution. Employing two-photon transitions from F=1, mF=1→F=2, mF=-1 (F is the quantum number of total atomic angular momentum, mF is the ...

European Journal of Combinatorics, 1982 In the first section of this paper it is shown that the bipartite Ramsey number br(m, n) satisfies br(m, n)⩽2m(n−1)+1. (Beineke and Schwenk [1] conjectured br(m, n) = 2m(n−1) + 1 but Irving [17] showed that equality does not always hold.) The second section gives a conjecture for the Ramsey numbers of the complete graphs, and lastly the numbers of ...

Journal of the Royal Anthropological Institute, EarlyView.Recent years have seen landmark progress in our understanding of early Homo sapiens occupation of Europe, owing to new excavations and the application of new analytical methods. Research on British sites, however, continues to lag. This is because of limitations inherent in existing cave collections, and limited options for new fieldwork at known sites.

, 2012 Let C_1 and C_2 be strong amalgamation classes of finite structures, with disjoint finite signatures sigma and tau. Then C_1 wedge C_2 denotes the class of all finite (sigma cup tau)-structures whose sigma-reduct is from C_1 and whose tau-reduct is from ...

History, EarlyView.Abstract In the summer of 1919, W. T. Goode, the Manchester Guardian’s special correspondent in Russia and the Baltic, was arrested in the Estonian capital Tallinn and briefly detained aboard a British warship. Goode's detention caused a furore, leading to accusations of kidnap, heated commentary in the press and questions in parliament.

Insights from the Presidential Addresses to the Agricultural Economics Society
Journal of Agricultural Economics, EarlyView.ABSTRACT The Society's published presidential addresses have embraced a wide range of subject matter, reflecting a ‘road well travelled’ in agricultural economics. The areas covered include the development and use of data and statistics, lessons from history, sectoral analysis, land economics, international trade and international development.

Individualised niches in a variable environment—Consequences for environmental change responses
Methods in Ecology and Evolution, EarlyView.Abstract Intraspecific trait variation (ITV) can be important for population performance in a variable and changing environment because individuals with different traits have different fitness responses. Furthermore, there are three mechanisms via which individuals can interact with their environment to potentially improve fitness: niche conformance ...

Field‐level crop choice responses to weather‐induced yield shocks in the US Corn Belt
American Journal of Agricultural Economics, EarlyView.Abstract As climate change increases the frequency and severity of extreme heat events, farmers are expected to face greater variability in crop yields. Using 10 million field‐level observations, this study examines how farmers in the US Corn Belt adjust corn–soybean rotation decisions in response to yield shocks largely driven by weather fluctuations.
