Beyond the size: Assessing the influence of synthesis parameters on ZIF-8 monolith degradation in aqueous environments

José de Jesús Velazquez-Garcia, Susann Frenzke, Dina Huanaco, H. Sanchez Cornejo et autres

This article reports the room-temperature synthesis of ZIF-8 monoliths, systematically varying synthesis parameters while maintaining a constant metal:ligand ratio of 1:7.9. The washing procedure, aging time, centrifugal speed, precursor concentration, solvent type, ammonia concentration, and metal salt were changed to investigate their …

The AI Use Gap: Visibility Management of Generative AI Use in Higher Education in the Peruvian Andes

Saríah Fanny Oré Gálvez, Cecilia Choque Pomasunco, Alex Foyams Molina Linares, Walter Víctor Castro Aponte et autres

The study examines discrepancies between personally reported and declared use of generative artificial intelligence (GenAI) among university students from a public university located in the Peruvian Andes, operationalized as the AI Use Gap, an exploratory discrepancy indicator based on two self-reported measures. …

Kirkwood-Dirac Nonpositivity Is a Necessary Resource for Quantum Computing

Anonymous, Songqinghao Yang, Nicole Yunger Halpern, Stephan De Bièvre et autres

We elucidate the boundary between classical and quantum computation by constructing qubit Clifford circuits with nonstabilizer inputs that can be efficiently simulated classically. We do so by casting the quantum circuits realizable by defect braiding in the surface code in terms of …

Three-dimensional imaging of Morpho butterfly wing nanostructures using FIB-SEM techniques

Peter Newton, R. M. Langford, N. Huallanca Remón, Walter Víctor Castro Aponte et autres

Accurate three-dimensional imaging of natural nanostructures is critical to obtain a full understanding of how they produce their remarkable optical properties. In this study, we developed scanning electron microscopy techniques, using a focused ion beam, to reconstruct models of the nanostructures found …

Towards Exponential Quantum Improvements in Solving Cardinality-Constrained Binary Optimization

Haomu Yuan, Hanqing Wu, Kuan-Cheng Chen, Bin Cheng et autres

Cardinality-constrained binary optimization is a fundamental computational primitive with broad applications in machine learning, finance, and scientific computing. In this work, we introduce a Grover-based quantum algorithm that exploits the structure of the fixed-cardinality feasible subspace under a natural promise on solution …

Mapping Ecosystems in the Peruvian Andes Using Hyperspectral Imagery and Machine Learning

Daria-Ioana Radu, Hugo Lepage, Eustace P. G. Barnes, C. H. W. Barnes

Mapping the Peruvian Andes has high ecological value because its ecosystems are immensely diverse. These mountains shelter numerous endemic species that could be protected if informed decisions are made when delineating conservation zones. Rigorous analysis of high-altitude regions traditionally requires multiple field …

Risk-minimizing states for the quantum-phase-estimation algorithm

Joseph G. Smith, C. H. W. Barnes, David R. M. Arvidsson-Shukur

The quantum-phase-estimation algorithm (QPEA) is widely used to find estimates of unknown phases. The original algorithm relied on an input state in a uniform superposition of all possible bit strings. However, it is known that other input states can reduce certain Bayesian …
