This paper develops an approach to decompose farmland price time series into three components: permanent fundamental component, temporary fundamental component, and nonfundamental component. This decomposition is useful for studying the importance of fundamental versus nonfundamental factors in explaining farmland price behavior and the dynamic response of farmland price to shocks to each of th...

Lameness is an economically important problem in dairy cattle worldwide. Economic losses resulting from lameness arise not only from the cost to treat clinical cases but also from decreased milk production, decreased reproductive efficiency and premature culling. New York researchers estimate the total cost of lameness per 100 cows per year to be nearly $9000. The average incidence was 30 cases...

A unique aspect of protein translocation across the peroxisomal membrane is that folded and oligomeric proteins get across this membrane (Purdue and Lazarow, 2001). The generality of this rule, its specific features, and its mechanism are not fully understood. A paper in this issue addresses, in a very thorough fashion, the assembly, cofactor binding, and import of an oligomeric protein, acyl-C...

Cascades are a network phenomenon in which small local shocks can result in wide-spread fads, strikes, innovations, or power failures. Determining which initial shocks will result in the largest cascades is of interest to marketing, epidemiology, and computer networking. This paper surveys work in maximizing the size of cascades in social networks.

BACKGROUND Diabetes mellitus (DM) and cardiovascular disease are associated with dyslipidemia, but the detailed lipid molecular pattern in both diseases remains unknown. METHODS AND RESULTS We used shotgun mass spectrometry to determine serum levels of 255 molecular lipids in 316 controls, 171 DM, and 99 myocardial infarction (MI) events from a cohort derived from the Malmö Diet and Cancer st...

UNLABELLED Fatty acids (FA) play an integral role in brain function and alterations have been implicated in a variety of complex neurological disorders. Several recent genomic studies have highlighted genetic variability in the fatty acid desaturase (FADS1/2/3) gene cluster as an important contributor to FA alterations in serum lipids as well as measures of FA desaturase index estimated by rati...

INTRODUCTION Breastfeeding effects on cognition are attributed to long-chain polyunsaturated fatty acids (LC-PUFAs), but controversy persists. Genetic variation in fatty acid desaturase (FADS) and elongase (ELOVL) enzymes has been overlooked when studying the effects of LC-PUFAs supply on cognition. We aimed to: 1) to determine whether maternal genetic variants in the FADS cluster and ELOVL gen...

Tuna fisheries catch over three million tonnes of skipjack tuna (Katsuwonus pelamis) each year, the majority of which come from purse-seine vessels targeting fish associated with man-made fish aggregating devices (FADs). A significant challenge for fisheries management is to maximize the efficiency of skipjack tuna catches whilst minimizing the bycatch of small and immature bigeye (Thunnus obes...
