Some studies suggest that fishery yields can be higher with reserves than under conventional management. However, the economic performance of fisheries depends on economic profit, not fish yield. The predictions of higher yields with reserves rely on intensive fishing pressures between reserves; the exorbitant costs of harvesting low-density populations erode profits. We incorporated this effec...

Fluorescence probes represent an attractive solution for the detection of the biologically important Cu(I) cation; however, achieving a bright, high-contrast response has been a challenging goal. Concluding from previous studies on pyrazoline-based fluorescent Cu(I) probes, the maximum attainable fluorescence contrast and quantum yield were limited due to several non-radiative deactivation mech...

The objective of this paper is to provide an overview of the HybridMaize software (www.hybridmaize.unl.edu, verified 28 Feb. 2006), with emphasis on its practical applications based on our own experience and feedback from users. The Hybrid-Maize model is a computer program that simulates the growth and yield of a corn crop (Zea mays L.) under nonlimiting or water-limited (rainfed or irrigated) ...

The Staudinger ligation between an azido-protein and a phosphinothioester-derivatized surface is demonstrated to be an effective means for the site-specific, covalent immobilization of a protein. Immobilization yields of >50% are obtained in <1 min, and immobilized proteins have >80% of their expected activity. No other method enables more rapid immobilization or a higher yield of active protei...

Braunstein and Caves showed how quantum information can be used to deene a metric for quantum states, relying on attainability of a quantum information bound. We show that the bound is not generally attainable, but that a two-stage procedure of repeated measurements achieves the bound in the limit. We connect to the question of`non-locality without entanglement': can a joint measurement on n in...

Power consumption in VLSI systems has become a critical metric for design evaluation. Although power reduction techniques can be applied at every level of design abstraction, most automated power reduction techniques apply to the lower levels of design abstraction, such as the register-transfer or gate level. We therefore investigated the power reduction attainable by the evolving automated beh...

" But I have promises to keep, And miles to go before I sleep, And miles to go before I sleep. " ——Robert Frost, " Stopping By Woods on a Snowy Evening " I n 2000, the American Heart Association (AHA) embarked on an ambitious goal-setting process that ultimately targeted a 25% reduction in risk and death due to coronary heart disease by 2010. This was an audacious, perhaps even dream-like, goal...

The assessment of crop yield losses is needed for the improvement of production systems that contribute to the incomes of rural families and food security worldwide. However, efforts to quantify yield losses and identify their causes are still limited, especially for perennial crops. Our objectives were to quantify primary yield losses (incurred in the current year of production) and secondary ...
