In this paper, we describe our current work on exploring the consistency of read-only transactions (ROT) in real-time systems. A ROT is a transaction that only reads, but does not update any data items. Since there is a significant proportion of ROTs in several real-time systems, it is important to investigate how to process ROTs efficiently with separate algorithms. We identify three different...

The root rots of wheat, oats, barley, and rye are among the least conspicuous diseases of cereals, but they are among the most destructive. They are caused by many species of fungi, which are widespread and live on or in seed, soil, and dead plant refuse. They attack a large number of hosts and thrive under a wide range of conditions. To the many types of root rots in cereal crops many names ha...

A read-only transaction (ROT) does not modify any data. The main issues regarding processing ROTs are correctness, data currency and performance. Two-phase Locking (2PL) protocol is widely used for concurrency control with serializabilty as correctness criteria. Even though 2PL processes ROTs correctly with no data currency related issues, the performance deteriorates as data contention increas...

In this paper, we introduce a class of cubic rotation symmetric (RotS) functions and prove that it can yield bent and semi-bent functions. To the best of our knowledge, this is the second primary construction of an infinite class of nonquadratic RotS bent functions which could be found and the first class of nonquadratic RotS semi-bent functions. We also study a class of idempotents (giving Rot...

Recent research shows that the class of Rotation Symmetric Boolean Functions (RSBFs), i.e., the class of Boolean functions that are invariant under circular translation of indices, are potentially rich in functions of cryptographic significance. Here we present new results regarding the Rotation Symmetric (rots) correlation immune (CI) and bent functions. We present important data structures fo...

In 1999, Pieprzyk and Qu presented rotation symmetric (RotS) functions as components in the rounds of hashing algorithm. Later, in 2002, Cusick and Stănică presented further advancement in this area. This class of Boolean functions are invariant under circular translation of indices. In this paper, using Burnside’s lemma, we prove that the number of n-variable rotation symmetric Boolean functio...

The past twenty years has seen the field of postharvest biocontrol evolve into a sophisticated science with global research programs worldwide, numerous yearly publications, patented technologies, and the development of new commercial products. The use of these products, however, still remains limited. The practical application of postharvest biocontrol has changed from a very classical view of...

ABSTRACT Fusarium verticillioides, F. proliferatum, and Aspergillus flavus cause ear rots of maize and contaminate the grain with mycotoxins (fumonisin or aflatoxin). The objective of this study was to investigate the relationships between resistance to Fusarium and Aspergillus ear rots and fumonisin and aflatoxin contamination. Based on a previous study of 143 recombinant inbred lines from the...
