We study moduli of semistable twisted sheaves on smooth proper morphisms of algebraic spaces. In the case of a relative curve or surface, we prove results on the structure of these spaces. For curves, they are essentially isomorphic to spaces of semistable vector bundles.

Vacuum‐Formed Composites Based on a Polyolefin and a High Content of Biomass‐Waste Fillers
It is shown here that by the use of a very ductile polymer matrix, it is possible to vacuum‐form products that contain up to 25% of hard biofillers with still ductile properties. The results are promising and opens up for the use of engineered biocomposites derived from industrial side‐stream biofillers in vacuum‐formed products. A strategy to increase

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

A mechanism for freezing moduli into Minkowski spacetime
We discuss FLRW-cosmologies with negatively-curved spatial slices that induce a late-time freezing of all the moduli of an effective field theory through Hubble friction, independently of the moduli-space curvature.

The physical moduli of heterotic G 2 string compactifications
In previous works, an operator was developed for heterotic compactifications on ℝ2,1 × G 2 and AdS 3 × G 2, which preserves N = 1 d = 3 supersymmetry and whose kernel is related to the moduli of the compactification. The operator is described in terms of

Ultrahigh‐molecular‐weight polyethylene powders (<≈40 μm) with a bulk density of 260 g L−1 are prepared from a silica supported bisimine pyridine iron catalyst. The nascent product is disentangled and can be thermally densified without loss of its low viscosity.

When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

Dislocation‐Mediated Thermoelectric Performance and Mechanical Behavior
Dislocations can scatter phonons to reduce thermal conductivity, thereby enhance thermoelectric performance. However, dislocations also impact mechanical properties, leading to increased brittleness and altered plasticity. It is essential to clarify the complex relationship between dislocations, thermal transport, and mechanical stability to achieve a ...
