The problem of converting a regular expression to NFA is a fundamental problem that has been well studied. However, the two basic construction algorithms: (1) Thompson, (2) McNaughton-Yamada and Glushkov, both have disadvantages. In this paper: First, a “smart” parsing algorithm is developed which constructs a parse tree with at most (3l − 1) nodes form a regular expression with l literals; Sec...

Carménère is the emblematic grape of Chile. Recent studies indicate that it has a different polyphenolic profile than other commercial varieties of grape among other factors, due to its long maturation period. The grape and wine of Carménère stand out for having high concentrations of anthocyanins (malvidin), flavonols (quercetin and myricetin) and flavanols (catechin, epicatechin and epigalloc...

A Examples of TS distributions Example 1: Uniform distribution ⌘ ⇠ UBd(0,d). The uniform distribution satisfies the concentration property with constants c = 1 and c0 = e d by definition. Since the set {⌘|uT⌘ 1}\Bd(0, p d) is an hyper-spherical cap for any direction u of Rd, the the anti-concentration property is satisfied provided that the ratio between the volume of an hyper-spherical cap of ...

The Horvitz-Thompson estimator is a general estimator for a population total, which can be used for any probability sampling plan. This includes both sampling with and without replacement. • Let π i be the probability that the i th unit of the population is included in the sample (inclusion probability). • On each unit i, we measure a response y i , and typically seek to estimate: τ = N i=1 y i...

In my years at the U.S. Department of Health and Human Services, we have made tremendous progress in our efforts to improve the health, safety, and well-being of the American people. The Department's recent Steps to a HealthierUS initiative aims to help Americans live longer, better, and healthier lives by reducing the burden of diabetes, overweight, obesity, asthma, heart disease and stroke, a...

Bruce's Sport is a mutant grapevine (Vitis vinifera L.) with green and white variegated fruit derived from the Sultana variety. The white regions of tissue have decreased polyphenol oxidase (PPO) activity resulting in a reduced capacity for browning. Active PPO from Sultana grapes was purified and had an apparent molecular weight of 40,000 on sodium dodecyl sulfate-polyacrylamide gel electropho...

This work demonstrates that the own plant defence compounds, like resveratrol in grapes, can be used as a natural and ecological alternative to chemical pesticides. An extract from vine leaves was used to maintain the quality of post-harvested grapes. Specifically, an extract (95% water and 5% ethanol) of such leaves was prepared and, subsequently, different bunches of grapes were immersed in i...

Wines and grapes contain a large array of phenolic compounds belonging to non-flavonoids and flavonoids. This study evaluates the polyphenolic contents of six commercial red and white Macedonian wines and four grape varieties. Spectrophotometric methods were applied for the determination of the total phenolics, the total flavonoids, the total anthocyanins and the total catechins. The efficiency...

The characterization of the metabolites accumulated in the grapes of specific cultivars grown in different climates is of particular importance for viticulturists and enologists. In the present study, the metabolite profiling of grapes from the cultivars, Alvarinho, Arinto and Padeiro de Basto, of two Portuguese Controlled Denomination of Origin (DOC) regions (Vinho Verde and Lisboa) was invest...

Wine makers wanting to know about natural fermentations (i.e., those not intentionally inoculated with yeast starter cultures) are interested in the kinds of yeasts present naturally on wine grapes at harvest and which yeasts gain predominance during must fermentation. This information about Arkansas grapes and naturally-fermented musts is not available. Therefore, the objective of this study w...
