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

open access: yesGlobal 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.

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

open access: yesJournal 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 ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Nonarchimedean geometry of Witt vectors [PDF]

open access: yesNagoya Mathematical Journal, 2013
AbstractLetRbe a perfect 𝔽-algebra equipped with the trivial norm. LetW(R) be the ring ofp-typical Witt vectors overRequipped with thep-adic norm. At the level of nonarchimedean analytic spaces (in the sense of Berkovich), we demonstrate a close analogy betweenW(R) and the polynomial ringR[T] equipped with the Gauss norm, in which the role of the ...

Remittance Income and Crime in Mexico

open access: yesReview of Development Economics, Volume 30, Issue 2, Page 1299-1316, May 2026.
ABSTRACT This study examines the relationship between remittance inflows and criminal activity in Mexico, a country with persistently high crime rates and among the world's top remittance recipients. Using a 41‐quarter panel dataset of municipalities covering 2013–2023, the analysis estimates elasticity parameters linking remittance income to different

On the center of the ring of differential operators on a smooth variety over $\bZ/p^n\bZ$

open access: yes, 2011
We compute the center of the ring of PD differential operators on a smooth variety over $\bZ/p^n\bZ$ confirming a conjecture of Kaledin. More generally, given an associative algebra $A_0$ over $\bF_p$ and its flat deformation $A_n$ over $\bZ/p^{n+1}\bZ ...
