Tip-dating methods are becoming popular alternatives to traditional node calibration approaches for building time-scaled phylogenetic trees, but questions remain about their application to empirical datasets. We compared the performance of the most popular methods against a dated tree of fossil Canidae derived from previously published monographs. Using a canid morphology dataset, we performed ...

Iran, as the biggest producer of dates, has 25 percent of the world date production. More than 400 varieties of dates have been identified in Iran. Dates have a high nutritional value they contain considerable amounts of sugar, vitamins and minerals. For instance, 2830 kilocalories of energy are obtained from one kilogram of dates. Dates are economically suitable replacements for sugar in bee f...

OBJECTIVE To determine whether the glycemic index (GI) and insulinemic index (II) of dates could be altered by Arabic coffee consumption. METHODS This randomized cross-over study was conducted at the Department of Nutritional Sciences, Faculty of Health and Medical Sciences, University of Surrey, Guildford, United Kingdom from November 2009 to February 2010. Healthy subjects (5 males, 5 femal...

Aim at the identification of Lingwu dates in the natural environment, a method for image segmentation based on BP neural network was put forward. After compressing the collected images, color feature of dates was analyzed in color spaces to select apposite color spaces and their components for recognition. And finally,the BP neural network was used to identify Lingwu dates. Experimental results...

Reproductive synchrony tends to be widespread in diverse species of plants and animals, especially at higher latitudes. However, for long-lived mammals, birth dates for different individuals can vary by weeks within a population. A mother's birth timing can reveal useful information about her reproductive abilities and have important implications for the characteristics and survival of her offs...

Infectious pathogens are known for their rapid evolutionary rates with new mutations arising over days to weeks. The ability to rapidly recover whole genome sequences and analyze the spread and evolution of pathogens using genetic information and pathogen collection dates has lead to interest in real-time tracking of infectious transmission and outbreaks. However, the level of temporal resoluti...

BACKGROUND One of the national mortality databases in the U.S. is the Beneficiary Identification and Record Locator Subsystem (BIRLS) Death File that contains death dates of those who have received any benefits from the Department of Veterans Affairs (VA). The completeness of this database was shown to vary widely from cohort to cohort in previous studies. Three other sources of death dates are...

We address the NP-hard problem of scheduling n independent jobs with release dates, due dates, and family setup times on a single machine to minimize the maximum lateness. This problem arises from the constant tug-of-war going on in manufacturing between efficient production and delivery performance, between maximizing machine utilization by batching similar jobs and maximizing customers’ satis...
