ABSTRACT This study aimed to evaluate the drying characteristics, nutritional quality, and shelf life stability of Indian anchovy (Stolephorus indicus) using ambient sun drying and solar drying under varying seasonal conditions in Poompuhar, Tamil Nadu, India. Solar drying consistently achieved lower moisture content (6%–23%) and improved drying rates (1.2 to 2.4-fold) compared to sun drying. It retained higher protein content (up to 70.5%), achieved microbiological safety, and superior sensory qualities. Shelf life extended up to 12 months under ambient storage. Overall, the findings establish solar drying as a more effective method for producing high-quality dried fish products in coastal regions.

We use symbolic computation (SC) and homological perturbation (HPT) to compute a resolution of the integers $$\mathbb {Z}$$ over the integer group ring of G, the fundamental group of the Klein bottle. From this it is easy to read off the homology of the Klein bottle as well as other information.

We report single-molecule detection of Hg(2+) by threading an Hg(2+)-mediated DNA duplex through α-hemolysin nanopores, which generates characteristic three-level current patterns and enables the unambiguous detection of Hg(2+). This strategy precludes any background interference and features high sensitivity and selectivity. Moreover, the platform could be readily integrated with aptamers and molecular beacons, offering extended possibilities for the construction of a new DNA-based nanopore sensing system.

We show that for binary classification variables, Gini and Pearson purity measures yield exactly the same tree, provided all the other parameters of the algorithms are identical. A counter-example for ternary classification variables is given.

<div class="htmlview paragraph">The Adaptive Multiple Euler Domains technology in MSC.Dytran has been extended for the Multi-material Euler Solver. This paper demonstrates the application of this new method to the dynamics of fuel tank filling. The interest in applicability of MSC.Dytran to fuel tank filling originated from a major car manufacturer. The model includes both the fuel and the air inside the tank. The simulation process starts with properly initializing the fuel and air inside the tank under gravity loading. The fuel filling process will then be demonstrated, including the venting of air through a venting tube. The simulation is performed with MSC.Dytran.</div>

We used computer aided symbolic computation in our previous papers to explore solutions of partial differential equations in a way that involves a synergistic application of symbolic and numeric methodologies. Here we review the results thus far and present a few examples of this emerging methodology applied to the nonlinear Burgers equation. The continued development of the hybrid methodology is presented with the hope of inspiring new thought in utilizing hybrid symbolic and numeric manipulation for solving the equations of mathematical physics from a fundamental perspective: A new kind of thinking beyond what we call computer science today. We see an opportunity to revisit the very foundations of scientific computing armed with new symbolic computational tools that complement the numerical power of modern machines.
