The Arg92Cys colipase polymorphism impairs function and secretion by increasing protein misfolding

open access: yesJournal of Lipid Research, 2013
Colipase is essential for efficient fat digestion. An arginine-to-cysteine polymorphism at position 92 of colipase (Arg92Cys) associates with an increased risk for developing type-2 diabetes through an undefined mechanism. To test our hypothesis that the

Time Lag

open access: yesJournal for the Anthropology of North America, 2019
AbstractThis article draws on ethnographic fieldwork with emergency responders in southern Arizona and northern Sonora that I conducted between 2015 and 2017 and my professional training and volunteer service as a paramedic. In retelling an episode when an aspiring wildland firefighter collapsed and died in a remote desert in the southwestern United ...

Time lag effects of COVID-19 policies on transportation systems: A comparative study of New York City and Seattle

open access: yesTransportation Research Part A: Policy and Practice, 2021
The unprecedented challenges caused by the COVID-19 pandemic demand timely action. However, due to the complex nature of policy making, a lag may exist between the time a problem is recognized and the time a policy has its impact on a system.

In vitro lipid peroxidation of LDL from postmenopausal cynomolgus macaques treated with female hormones

open access: yesJournal of Lipid Research, 1999
Premenopausal women and postmenopausal women given estrogen are protected from cardiovascular diseases compared with men. Previous studies investigated whether estrogen treatment protects low density lipoprotein (LDL) from in vitro oxidation as a ...

Time-Lag Selection for Time-Series Forecasting Using Neural Network and Heuristic Algorithm

open access: yesElectronics, 2021
The time-series forecasting is a vital area that motivates continuous investigate areas of intrigued for different applications. A critical step for the time-series forecasting is the right determination of the number of past observations (lags).

Time-optimal control of time-lag systems with time-lag controls

open access: yesJournal of Mathematical Analysis and Applications, 1975
AbstractThis paper considers the time-optimal control problem for a class of time-lag systems in which the time-lag is the control variable. It is shown that under certain conditions, the attainable set at any time t is convex, compact, and varies continuously with t. Using this result, a necessary condition for the time-optimal controls in the form of
