Quantum Carnot Bound from Petz Recovery Maps

Advanced Physics Research, EarlyView.
A quantum bound (ηP$\eta_P$, the Petz Limit) is derived for the efficiency (η$\eta$) of a heat engine utilizing two‐level quantum systems (qubits) as the working substance. This limit, based on Petz recovery maps, is stricter than the classical Carnot limit (ηC$\eta_C$) for irreversible cycles.

Universal Entanglement and an Information‐Complete Quantum Theory

Advanced Physics Research, EarlyView.
This Perspective summarize an informationcomplete quantum theory which describes a fully quantum world without any classical systems and concepts. Here spacetime/gravity, having to be a physical quantum system, universally entangles matter (matter fermions and their gauge fields) as an indivisible trinity, and encodes information‐complete physical ...

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

The Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

“Am I being responsible?”: Navigating coming‐of‐age transitions through personal financial information management

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This research explored how young adults (ages 18–25) learn to use financial records and the roles financial records play in their experiences in coming to see themselves as financially mature social actors. The contribution of this paper is a revised model of transitions theory that includes personal information management (PIM) as an ...
