Polyurethanes are widely used in car paint formulations. During thermal degradation, such polymeric systems can generate powerful asthmatic sensitizing agents named isocyanates. In body repair shops, the thermal degradation of car paint can occur during abrasive processes that generate enough heat to involve release of isocyanates in air. An environmental monitoring study was performed in two b...

Fourier transform infrared (FTIR) and gel permeation chromatography (GPC) wre respectively utilized in determining the changes in isocyanate (NCO) concentration and molecular weight (MW) and its distribution (MWD) in polyurethanes during their cure and postcure stages. Samples, originally cured at 45°C, were taken through accelerate aging tests at various temperatures. The FTIR and GPC anal...

Abstract High-density memory devices are essential to sustain growth in information technology (IT). Furthermore, brain-inspired computing the future of IT businesses such as artificial intelligence, deep learning, and big data. Herein, we propose a facile hierarchical nickel cobaltite (NCO) quasi-hexagonal nanosheet-based memristive device for multilevel resistive switching (RS) synaptic learn...

Recombinants isolated from most meiotic intragenic recombination experiments in maize, but not in yeast, are borne principally on crossover chromosomes. This excess of crossovers is not explained readily by the canonical double-strand break repair model of recombination, proposed to account for a large body of yeast data, which predicts that crossovers (COs) and noncrossovers (NCOs) should be r...

All-optical magnetization control has recently been garnering considerable attention to realize next-generation ultrafast magnetic information devices. Here, employing a magneto-optical Kerr effect (MOKE) microscope, we observed the laser-induced switching of ferrimagnetic oxide NiCo2O4 (NCO) epitaxial thin films with perpendicular anisotropy, where sample was pumped by 1030 nm laser pulses, an...

Meiotic mutant (2n) gametes formed by first-division restitution without crossover (FDR-NCO) are expected to be superior to FDR with crossover (FDR-CO) because they transmit to the progeny, without disruption by recombination, almost 100% of the parental genotype. FDR-CO transfers approximately 80% of the parental heterozygosity and a large fraction of the epistatic interactions. Another geneti...

The majority of South African sugarcane varieties are resistant to mosaic but two widely grown varieties, NCo 376 and.NCo 293, are highdy susceptible. Application of Temik (aldicarb) to the soil at planting was not beneficial in controlling mosaic. Mosaic transmission was restricted to January to May but very rapid spread only occurred in mid January to March, i.e. late summer and early autumn....

Recently, combinatorial optimization problems have aroused a great deal of interest in Machine Learning, leading to interesting advances Neural Combinatorial Optimization (NCO): the study data-driven solvers for NP-Hard based on neural networks. This paper studies benefit Transfer Learning NCO by evaluating how model training can be improved taking advantage knowledge learned while solving simi...
