Proper actions and proper invariant metrics
, 2008 We show that if a (locally compact) group $G$ acts properly on a locally compact $\sigma$-compact space $X$ then there is a family of $G$-invariant proper continuous finite-valued pseudometrics which induces the topology of $X$.

Advanced Biology, EarlyView.Chromatin, which organizes DNA, changes its structure to adapt to stress like high oxygen levels (hyperoxia), which can damage cells. Researchers developed a technique to observe these changes and found variability in how different parts of chromatin remodel.

Exactness of locally compact groups
, 2017 We give some new characterizations of exactness for locally compact second countable groups. In particular, we prove that a locally compact second countable group is exact if and only if it admits a topologically amenable action on a compact Hausdorff ...

Advanced Engineering Materials, Volume 27, Issue 14, July 2025.The study presents an efficient simulation approach for the polymer laser powder bed fusion process polymers process, validated with polyamide 12, polyamide 6, and polyetherketoneketone. It shows that inter layer time affects part density, with 90s yielding dense parts.

The unique ergodicity of equicontinuous laminations
, 2010 We prove that a transversely equicontinuous minimal lamination on a locally compact metric space $Z$ has a transversely invariant Radon measure. Moreover if the space $Z$ is compact, then the tranversely invariant Radon measure is shown to be unique up ...

On uniformly locally compact spaces
Journal of Mathematical Analysis and Applications, 1970 In this paper we shall extend certain results on topological groups to uniform spaces. In Section 2 we generalize a result of Gleason [2]. In Section 3 we show that every uniformly locally compact space can be “approximated” by locally compact metrizable spaces.

Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed FeCr(Si)N Stainless Steel
Advanced Engineering Materials, Volume 27, Issue 14, July 2025.The alloying element Nitrogen enhances stainless steel strength, corrosion resistance, and stabilizes austenite. This study develops austenitic FeCr(Si)N steel production via powder metallurgy. Fe20Cr and Si3N4 are hot isostatically pressed, creating an austenitic microstructure.

Convolution on locally compact spaces
Journal of Mathematical Analysis and Applications, 1973 In this paper a convolution similar to that defined by Ionescu TulceaSimon [3] is developed by means of an extension of the underlying convolution of functions to convolution of measures. The hypotheses under which the extension obtains are relatively weak and it is to be noted that associativity is not assumed (an elementary non-associative example is

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components
Advanced Engineering Materials, EarlyView.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.

Powder Metallurgy Preparation of Metastable β Ti–Cr–Ge Alloys for Medical Applications
Advanced Engineering Materials, EarlyView.This study develops metastable β Ti–Cr–Ge alloys using powder metallurgy for biomedical implants. The Ti–10Cr–2Ge alloy exhibits superior mechanical performance with high yield strength (>1100 MPa), low Young's modulus (<85 GPa), and excellent strain hardening behavior.
