Weak Antilocalization Effect for Detection of Dirac Fermions in Capped Bi2Te3 Epitaxial Film

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
The transport properties of a sample grown by molecular beam epitaxy are investigated. The sample consists of a Bi2Te3 epitaxial film deposited on BaF2 substrate and capped with a BaF2 cap to prevent the topological surface states (TSS) deterioration.

Improving the Chain Sampling Plans Based on Cpm Index

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT A recent article discusses the design of chain sampling plans based on the Cpm index where a sample is randomly selected from the lot, and the Cpm value of the sample is compared with the threshold (ka). If the Cpm is lower than ka, the lot is rejected, otherwise, the Cpm values of previous m lots are examined; if m‐1 of the Cpm values exceed ...

Toward Useful Quantum Kernels

open access: yesAdvanced Quantum Technologies, EarlyView.
The hybrid approach to Quantum Supervised Machine Learning is compatible with Noisy Intermediate Scale Quantum (NISQ) devices but hardly useful. Pure quantum kernels requiring fault‐tolerant quantum computers are more promising. Examples are kernels computed by means of the Quantum Fourier Transform (QFT) and kernels defined via the calculation of ...

A Study Demonstrating That Using Gravitational Offset to Prepare Extraterrestrial Mobility Missions Is Misleading

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

Reconceptualizing Out‐of‐Field Teachers' Professional Development and Classroom Implementation: A Boundary Crossing Approach

open access: yesScience Education, EarlyView.
ABSTRACT Reform‐oriented instruction is advocated in secondary science, encouraging students to engage with the experimental and epistemic practices of science. It is challenging for teachers though, especially for out‐of‐field teachers. This study focuses on biology and chemistry teachers who are called to teach middle‐school physics.
