Abstract:

Twisted Edwards curves have been at the center of attention since their introduction by Bernstein et al. in 2007. The curve ED25519, used for Edwards-curve Digital Signature Algorithm (EdDSA), provides faster digital signatures than existing schemes without sacrificing security. The CURVE25519 is a Montgomery curve that is closely related to ED25519. It provides a simple, constant time, and fast point multiplication, which is used by the key exchange protocol X25519. Software implementations of EdDSA and X25519 are used in many web-based PC and Mobile applications. In this paper, we introduce

Abstract:

In cryptography, elliptic curve cryptography (ECC) is considered an efficient and secure method to implement digital signature algorithms (DSAs). ECC plays an essential role in many security applications, such as transport layer security (TLS), internet protocol security (IPsec), and wireless sensor networks (WSNs). The proposed designs of ECC hardware implementation only focus on a single ECC variant and use many resources. These proposals cannot be used for resource-constrained applications or for the devices that need to provide multiple levels of security. This work provides a multi-functi

This paper establishes that the extended Euclidean algorithm (EEA) implemented in a division-free manner is faster than the Lagrange algorithm with a similar level of optimization when it comes to halving the size of scalars found in the equations of elliptic curve signature verification.

"Mermaids and Other Undines: Medieval Representations of Scandinavian Aquatic Figures. Without claiming to be exhaustive, this article compares the different aquatic figures of Scandinavian imagination, and the representations relating to Scandinavia, taking into account their cosmic aspect. This paper highlights the close connection of these creatures with time, weather and music, and the evolution of the representation of sea creatures that embody geography and climate, real or fantasized. These representations evolve, especially because of the important Christianization process that they un

The iron chelator ethylene diamine-di-orthohydroxyphenyl acetic acid (EDDHA) was fed to 79 colostrum-deprived piglets with or without bovine or porcine serum immunoglobulins. Piglets that received bovine immunoglobulins from birth to day 14 had significantly lower survival rates, average daily weight gains and plasma immunoglobulin concentrations than piglets that received porcine immunoglobulins on the first day after birth. Piglets that received porcine immunoglobulins on day 1 followed by either bovine or porcine immunoglobulins on days 2–14 had significantly higher average daily gains than

Abstract:

Multiple studies have examined the use of chelates to correct pH-induced Fe chlorosis. Here we report the effects of three common chelates on prevention of Fe chlorosis in two sensitive species at high pH. Calibrachoa and soybean were grown in three media pH ranges (6.0 to 6.5, 7.0 to 7.2, and 7.6 to 7.8) and supplied with 1 mg·L−1 Fe as Fe-EDTA, Fe-DTPA, or Fe-EDDHA through fertigation. Chelate effectiveness was quantified by chlorosis rating and dry mass. In Calibrachoa, all three chelates prevented chlorosis at media pH up to 6.5, but above pH 7.2 only Fe-EDDHA was effective.

The antibacterial properties of lactoferrin, EDDHA and HBED, with and without porcine immunoglobulins, were compared in vitro using E. coli 0 157 K88. Lactoferrin and EDDHA inhibited the growth of E. coli over a 12-h incubation period, while HBED had no effect on bacterial growth.

Chelate-assisted phytoextraction has been proposed as an effective approach to removing heavy metals from contaminated soil through use of high biomass plants. The aim of the present study was to compare the efficiency of the two chelators: EDTA and biodegradable EDDS in enhancing Cu uptake and translocation by Brassica napus L. grown on moderately contaminated soil and treated with increasing concentrations of EDTA or EDDS. Increasing amounts of EDDS caused a serious growth depression of Brassica napus and an increase in shoot metal concentrations. Growth depression limited the actual amount

Aminopolycarboxylic acid (APCA) complexones, commonly referred to as ligands or chelating agents, like ethylenediaminetetraacetic acid (EDTA) and diethylenetriaminepentaacetic acid (DTPA), are commonly used in soluble fertilizers to supply copper (Cu), iron (Fe), manganese (Mn), and/or zinc (Zn) to plants. Offsite runoff and contamination of surface waters with these chelating agents is of increasing concern as a result of their reported ability to remobilize heavy metals in sediments and their low susceptibility to biodegradation.
