Quick Record Lookup without an Index

INTRODUCTION As with most database software the SAS System allows data sets to be indexed on key variables. An index is a secondary file that stores the unique values of the key and their positions on the data set. Once a data set is indexed SAS will directly lookup a record when a WHERE clause is used. Up to a certain percentage of records, the index will retrieve data much more quickly than a...

Terrestrial Freeze-thaw Monitoring on the Tibet Plateau Using Passive Microwave Remote Sensing

The terrestrial cryosphere comprises cold areas of Earth’s land surface where water is either permanently or seasonally frozen. This includes most regions north of 40 degrees North latitude and most mountainous regions where elevation is greater than 1000m [1]. Permafrost is ground that perennially at or below 0 throughout the year. Above the permafrost is the active layer, which experiences su...

Quick Relief from Anxiety and Stress Without Tranquilizer Drugs

Animal studies of lemon balm have produced impressive results with regard to stress reduction. In one study, researchers gave low doses of a lemon balm extract to mice. They observed a decrease in anxiety-related behaviors when the animals were placed in an unfamiliar environment.6 In the same study, higher doses of the lemon balm extract produced analgesic (pain-relieving) effects. Most dramat...

Freeze-Thaw Bayesian Optimization

In machine learning, the term “training” is used to describe the procedure of fitting a model to data. In many popular models, this fitting procedure is framed as an optimization problem, in which a loss is minimized as a function of the parameters. In all but the simplest machine learning models, this minimization must be performed with an iterative algorithm such as stochastic gradient descen...
