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.

Efficient Dynamics: Reduced‐Order Modeling of the Time‐Dependent Schrödinger Equation

Advanced Physics Research, EarlyView.
Reduced‐order modeling (ROM) approaches for the time‐dependent Schrödinger equation are investigated, highlighting their ability to simulate quantum dynamics efficiently. Proper Orthogonal Decomposition, Dynamic Mode Decomposition, and Reduced Basis Methods are compared across canonical systems and extended to higher dimensions.

The Structure of Field‐Aligned Current Systems as Inferred From the Multiscale Minimum Variance Analysis

Earth and Space Science
Auroral field‐aligned currents (FACs) have an intrinsic complexity caused by the superposition of contributions from a broad spectrum of scales and diversity of locations.

Distal femoral morphology as a risk factor for osteoarthritis

The Anatomical Record, EarlyView.
Abstract Osteoarthritis (OA) is a leading cause of disability affecting millions of adults in the United States, commonly resulting in the need for total knee arthroplasty (TKA) to restore mobility and quality of life. This study investigates potential differences in baseline distal femoral shape between individuals who received TKA due to OA and a ...

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.
