We demonstrate that symmetric-key cryptography can be used for both read and write access control. One-time write access can be granted by handing over an encryption key, and our encryption framework allows the revocation of previously granted rights. The number of keys to be managed explicitly grows linearly with the number of access control policies a user defines, making security manageable....

We consider a 5D extension of the DFSZ axion model that addresses both quality and fermion mass hierarchy problems, predicts flavour-dependent, off-diagonal axion-fermion couplings. The is part complex scalar field charged under U(1)$_{PQ}$ symmetry spontaneously broken in bulk, insensitive to explicit PQ breaking on UV boundary. Bulk Standard Model fermions interact with two Higgs doublets can...

OBJECTIVE This systematic review examines the impact of non-menthol flavours in tobacco products on tobacco use perceptions and behaviours among youth, young adults and adults. DATA SOURCES English-language peer-reviewed publications indexed in 4 databases were searched through April 2016. STUDY SELECTION A search strategy was developed related to tobacco products and flavours. Of 1688 arti...

The use of multiple fermentations is one of the most specific characteristics of Maotai--flavoured liquor production. In this research, the variation of volatile composition of Maotai-flavoured liquor during its multiple fermentations is investigated using statistical approaches. Cluster analysis shows that the obtained samples are grouped mainly according to the fermentation steps rather than ...

Dairy nutrients, such as calcium, are particularly important in adolescence, a critical time for growth and development. There are limited Australian data following individuals through adolescence, evaluating changes in dairy nutrient and dairy product consumption. We used a validated food frequency questionnaire to investigate consumption in adolescents participating in both the 14 and 17 year...

AIM To investigate any association between dental erosion and its potential dietary risk factors in a group of schoolchildren in Benghazi, Libya. STUDY DESIGN A cross-sectional observational study. METHODS A random sample of 12-year-old schoolchildren in 36 randomly selected schools completed a questionnaire to provide dietary data and underwent dental examination. Dental erosion was assess...

OBJECTIVE To determine the association of beverage consumption with obesity in Mexican American school-aged children. DESIGN Cross-sectional study using the baseline data from a cohort study. Mothers and children answered questions about the frequency and quantity of the child's consumption of soda, diet soda, other sugar-sweetened beverages, 100% fruit juice, milk and water. The questions we...

Inadequate Ca intakes are a concern for global public health. In France, most dietary Ca is provided by dairy products: milks, fermented milks (mostly yogurts), dairy desserts and cheeses. The present dairy database (n 837) included milks (n 101), fermented milks, yogurts and other fresh dairy products (n 326), desserts (n 162) and a wide variety of cheeses (n 248). Energy and nutrient values w...
