We show how the use of superalgebraic methods sheds new light on some classical themes of representation theory and it leads to significant simplifications of traditional ...

Biocomposites produced with agro‐industrial waste from castor hulls and pinewood bonded with urea‐formaldehyde adhesive, intended for application as thermal insulation in buildings. ABSTRACT The production of composite particleboards with agricultural waste has been the focus of many studies that aim to address environmental problems due to waste ...

Geometric lower bounds for generalized ranks [PDF]
We revisit a geometric lower bound for Waring rank of polynomials (symmetric rank of symmetric tensors) of Landsberg and Teitler and generalize it to a lower bound for rank with respect to arbitrary varieties, improving the bound given by the "non ...

Prediction of Cure‐Induced Wrinkles Aimed at the Manufacturing of Large Wind Turbine Blades
The step‐wise progression of the development of cure‐induced wrinkles. Before curing, at room temperature the laminate is resting at the mould face. In the next step, the wrinkle is developing due to thermal gradients. At the end of curing, the composite has cooled down and the undulation is left in, byt the increase in resin stiffness across the ...

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

The principal result is a primary decomposition of ideals generated by the (2x2)-subpermanents of a generic matrix. These permanental ideals almost always have embedded components and their minimal primes are of three distinct heights.

Approximating the Permanent with Fractional Belief Propagation [PDF]
We discuss schemes for exact and approximate computations of permanents, and compare them with each other. Specifically, we analyze the Belief Propagation (BP) approach and its Fractional Belief Propagation (FBP) generalization for computing the ...

A Study on Preventing Thermal Runaway of Contaminated Ammonium Nitrate Prill in Bulk Storage
Schematic illustration of a contaminated region of ammonium nitrate prill undergoing exothermic decomposition, producing gases containing NOx. The interstitial flow of these heated gases rapidly raises the temperature of ammonium nitrate along the flow path.

ABSTRACT Nanocomposite permanent magnets with reduced rare‐earth content represent a promising class of materials for next‐generation high‐performance applications. However, asynchronous precipitation of soft and hard magnetic phases often results in grain size mismatch and limited coercivity.
