  • Although metabolites and energy balance have long been known to play roles in the regulation of food intake, the potential role of fatty acid metabolism in this process has been considered only recently. Fatty acid synthase (FAS) catalyzes the condensation of acetyl-CoA and malonyl-CoA to generate long-chain fatty acids in the cytoplasm, while the breakdown of fatty acids (h-oxidation) occurs in mitochondria and is regulated by carnitine palmitoyltransferase-1 (CPT-1), the rate-limiting step for the entry of fatty acids into the mitochondria....

  • Empirical evidence suggests that movements in international relative prices (such as the real exchange rate) are large and persistent. Nontraded goods, both in the form of ¯nal consumption goods and as an input into the production of ¯- nal tradable goods, are an important aspect behind international relative price movements. In this paper we show that nontraded goods have important impli- cations for exchange rate behavior, even though °uctuations in the relative price of nontraded goods account for a relatively small fraction of real exchange rate movements.

  • One advantage of conducting after-hours building walk-throughs to collect data on office equipment power status is that more buildings can be surveyed with a given amount of time and money. On the other hand, the data collected represents a snapshot in time, and does not capture variations in user behavior over time, which would require automated long-term time series metering of equipment power state and power levels. This is our most robust sample of buildings to date for collecting data on the after hours power status of office equipment.
