Abstract:
Linear complexity is an important criterion to characterize the unpredictability of pseudo-random sequences, and large linear complexity corresponds to high cryptographic strength. Pseudo-random Sequences with a large linear complexity property are of importance in many domains. In this paper, based on the theory of inverse Gray mapping, two classes of new generalized cyclotomic quaternary sequences with period pq are constructed, where pq is a product of two large distinct primes. In addition, we give the linear complexity over the residue class ring Z4 via the Hamming weights of their Fourie

Abstract:
Magnetic quaternary chitosan salt CS/EPTAC/Fe3O4 was used for the removal of acid red 1 (AR1), xylenol orange (XO) and alizarin red (AR) in single, binary and ternary systems. In the single system, the maximal adsorption capacity was 781.55 for AR1, 537.40 for XO and 992.61 mg g−1 for AR at pH 3.0 and 25 °C. The adsorption kinetics of the three dyes followed the pseudo-second-order model. In the multicomponent system, preferential adsorption was observed for AR at low adsorbent quantities due to the small size of the molecule. When the adsorbent amount was greater, AR1 was adsorbed first becau

Abstract:
The study investigates the effectiveness and mechanism of the adsorption of malachite green from single and mixed dyes aqueous solutions by an adsorbent prepared from acid-treated Parkia biglobosa sawdust. The adsorbent was characterized using different techniques, and the adsorption was conducted in single, binary, ternary and quaternary dye systems under different experimental conditions. Experimental results were subjected to different isotherm and kinetics models. The adsorption process was endothermic and thermodynamically feasible with the removal efficiency increasing with increase in a

Abstract:
The Cs2SeO4-H2SeO4-H2O and Cs2SeO4-Li2SeO4-H2O systems were studied at 30 °C as a basis for determining the conditions for formation of the compound Cs4LiH3(SeO4)4, which has been observed to undergo a ferroelectric phase transition. The results of a solubility study were used to construct a pseudo-ternary cross-section for CsLiSeO4-CsHSeO4-H2O in the quaternary system Cs2SeO4-Li2SeO4-H2SeO4-H2O, which demonstrated that, in the region of crystallization of the compound of interest, a substance with the composition Cs4LiH3(SeO4)4 is actually formed.

Abstract:
New Cu-based bulk amorphous alloys exhibiting a large supercooled liquid region and good mechanical properties were formed in a quaternary Cu-Ni-Zr-Ti systems consisting of only metallic elements. The compositional range for the formation of the amorphous alloys that have high glass forming ability (GFA) (> 3 mm diameter) and large supercooled liquid region (> 50 K) is defined in the pseudo-ternary phase diagram Cu-Ni-(Zr, Ti). A bulk amorphous Cu54Ni6Zr22Ti18alloy with the diameter of 6 mm can be prepared by copper mold casting. The Cu54Ni6Zr22Ti18alloy shows glass transition temperatur

Abstract:
As much as 3.05 m of land subsidence was observed in 1979 in the Houston-Galveston region as a result primarily of inelastic compaction of aquitards in the Chicot and Evangeline aquifers between 1937 and 1979. The preconsolidation pressure heads for aquitards within these two aquifers were continuously updated in response to lowering groundwater levels, which in turn was caused by continuously increasing groundwater withdrawal rates from 0.57 to 4.28 million m3/day. This land subsidence occurred without any management of changes in groundwater levels. However, the management of recovering grou
