Analysis of image formation in optical palpation

open access: yesJournal of Biophotonics, EarlyView.
Optical palpation is an emerging elastography technique that generates images of mechanical stress at the tissue surface, with applications in intraoperative cancer detection. Image formation is simulated using finite element analysis and validated with experiments on silicone phantoms, providing an analysis of trends in detectability, feature ...

Varieties and algebraic algebras of bounded degree

open access: yesJournal of Pure and Applied Algebra, 1998
Abstract We study varieties of associative algebras over an infinite field. We prove that any variety is generated by an algebraic algebra of bounded degree over a commutative algebra and determine when it can be generated by an algebraic algebra over a field. We also give upper and lower bounds for the minimal algebraic degree of the algebra Mn(G).

Strong External Difference Families and Classification of α $\alpha $‐Valuations

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT One method of constructing (a2+1,2,a,1) $({a}^{2}+1,2,a,1)$‐SEDFs (i.e., strong external difference families) in Za2+1 ${{\mathbb{Z}}}_{{a}^{2}+1}$ makes use of α $\alpha $‐valuations of complete bipartite graphs Ka,a ${K}_{a,a}$. We explore this approach and we provide a classification theorem which shows that all such α $\alpha $‐valuations ...

An ant colony genetic fusion routing algorithm based on soft define network

open access: yesIET Networks, EarlyView., 2022
Abstract Aiming at the problem that there are many paths in data forwarding in soft define network (SDN) network, and the optimal path is difficult to find, combined with the advantages of ant colony algorithm and Genetic algorithm (GA), a routing control strategy based on the ant colony genetic fusion algorithm is proposed.

Modelling the drying of single droplets of aqueous solutions of lactose and of maltodextrin

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract The average temperature of shrinking droplets is obtained from an enthalpy balance considering convection to or from the surroundings and cooling due to evaporation of solvent from the surface. This unique application of the fully implicit backward scheme captures the moisture values at all nodes in the grid, including at the centre and outer ...

On some properties of the asymptotic Samuel function

open access: yesMathematische Nachrichten, EarlyView.
Abstract The asymptotic Samuel function generalizes to arbitrary rings the usual order function of a regular local ring. Here, we explore some natural properties in the context of excellent, equidimensional rings containing a field. In addition, we establish some results regarding the Samuel slope of a local ring.
