The Burnside ring of the infinite cyclic group and its relations to the necklace algebra, λ-rings, and the universal ring of Witt vectors

Advances in Mathematics, 1989
Let \(a(t)=1+\sum_{n=1}a_ nt^ n \in {\mathbb{Z}}[[t]]\) be a formal power series with integral coefficients. The authors establish isomorphisms between: the Burnside ring \({\hat \Omega}(C)\) of the infinite cyclic group C, the Grothendieck ring \(\Lambda(Z)\) [\textit{A. Grothendieck}, Bull. Soc. Math.

Rendezvous in Space: Tech Diplomacy and the Commercial Space Era—A Study of Rendezvous and Docking Technologies and Space Exploration Co‐Operation Since the Cold War

Global Policy, EarlyView.
ABSTRACT On‐orbit rendezvous and docking constitute one of the most technically challenging activities in the history of space activities. As space endeavours mature to crewed missions, space rendezous and docking technologies (RDT) emerge as an area of technological innovation critical to advances in future crewed space exploration.

Predicting psychopathology symptom trajectories using machine learning: a 33‐year prospective study

Journal of Child Psychology and Psychiatry, EarlyView.
Background While previous literature has established a link between psychopathology symptom trajectories and psychosocial risk, most studies have not extended into adulthood or incorporated comprehensive risk measures. We aimed to identify symptom trajectories for externalizing and internalizing symptoms over a 25‐year span and predict them using ...

How Do SMEs Respond to Deglobalization? Insights from Italian SMEs in the Interwar Period (1936–1943)

Journal of Management Studies, EarlyView.
Abstract This study investigates how small and medium‐sized enterprises (SMEs) respond to deglobalization and economic nationalism, using historical evidence from fascist Italy, a period of autarky and restricted international trade. While prior research has focused primarily on larger firms, especially multinational enterprises (MNEs), the strategic ...

Using Drones for Large Mammal Monitoring

Mammal Review, Volume 56, Issue 3, September 2026.
Drones were used to obtain video data on animals and locations and distance from the midline was automatically determined by our pipeline so that the input for Distance sampling is generated. ABSTRACT Introduction The emergence of drones has profoundly transformed the field of large mammal monitoring, offering unprecedented capabilities for data ...

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14

Mathematische Nachrichten, Volume 299, Issue 8, Page 1894-1916, August 2026.
ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces

Petrogenesis and Tectonic Evolution of Cenozoic Magmatism in the Southernmost Northern Andes: Insights From Zircon Petrochronology

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study integrates new zircon U–Pb ages, zircon εHf(t)–δ18O isotopic data, and whole‐rock geochemistry to refine the temporal and spatial framework of magmatism in the southern Northern Andes (SNA) from ∼65 to 6 Ma. The San Lucas, Catamayo, Portachuela, and Gonzanamá batholiths and magmatic suites, along with Late Miocene plutons, display ...

Parental Time Use and the Gendered Socialization of Adolescents' Housework in China: A Cumulative Perspective

Journal of Marriage and Family, Volume 88, Issue 4, Page 974-989, August 2026.
ABSTRACT Objective This study examines how parental housework time and labor market participation during early childhood are associated with adolescents' housework participation. Background Prior research shows that parental time use is associated with adolescents' housework in gendered ways.

A trace–path integral formula over function fields

Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract We show that an arithmetic path integral over the ℓ$\ell$‐torsion of a Jacobian J[ℓ]$J[\ell]$ is equal to the trace of the Frobenius action on a representation of the Heisenberg group H(J[ℓ])$H(J[\ell])$, up to an explicitly determined sign.

Gene Expression and Alternative Splicing Regulate Phenotypic Plasticity of a Social Wasp

Ecology and Evolution, Volume 16, Issue 7, July 2026.
This study demonstrates that patterns of differential gene expression and alternative splicing are partially linked in a social wasp. In addition, colony‐level environmental variation drives far stronger transcriptomic divergence than genetic differences, highlighting that social environment plays a strong role in shaping developmental plasticity ...
