Cadmium (Cd) is a highly toxic heavy metal particularly susceptible to mobilization by anthropogenic and natural processes. The volcanic nature of oceanic islands in the Macaronesia geographical region such as Azores archipelago, located near Mid-Atlantic Ridge, reflected deep-sea shallow-water hydrothermal activities that release metals Cd seawater, affecting marine organisms integrating food ...

This paper describes a simple candidate one-way hash function which satis es a quasi-commutative property that allows it to be used as an accumulator. This property allows protocols to be developed in which the need for a trusted central authority can be eliminated. Space-e cient distributed protocols are given for document time stamping and for membership testing, and many other applications a...

A somewhere statistically binding (SSB) hash, introduced by Hubáček and Wichs (ITCS ’15), can be used to hash a long string x to a short digest y = Hhk(x) using a public hashing-key hk. Furthermore, there is a way to set up the hash key hk to make it statistically binding on some arbitrary hidden position i, meaning that: (1) the digest y completely determines the i’th bit (or symbol) of x so t...

The samples of 4 mushroom species from the genus Leccinum ((Leccinum pseudoscabrum (Kallenb.) Šutara, scabrum (Bull.) Gray, duriusculum (Schulzer ex Kalchbr.)
