High Upper Critical Field and Type II Superconductivity in Epitaxial Cubic W2N Thin Films

Advanced Science, EarlyView.
Superconducting thin films of stoichiometric W2N demonstrate a high upper critical field (Hc2) of ∼ 8.5 T, uncommon among binary transition metal nitrides. This robust superconducting response under high magnetic fields highlights the technological relevance of W2N for superconducting applications, e.g., integrated quantum and cryogenic electronics ...

DTC: Deep Tracking Control

Science Robotics
Legged locomotion is a complex control problem that requires both accuracy and robustness to cope with real-world challenges. Legged systems have traditionally been controlled using trajectory optimization with inverse dynamics. Such hierarchical model-based methods are appealing because of intuitive cost function tuning, accurate planning ...

Vendor Types, Attendance, Experience and Sales 2019–2021: Evidence From Five Rural Oregon Farmers Markets

Agribusiness, EarlyView.
ABSTRACT Farmers markets provide a direct‐to‐consumer marketing path for farmers and small businesses, facilitating customer discovery and product refinement. This paper explores farmers markets as a business incubator, with a focus on beginning vendors and resilience to a shock, namely, COVID‐19 market restrictions.

Cuckoo Search Based DTC of PMSM [PDF]

, 2018
Hysteresis controllers (HC) are used to limit the torque and flux in the control band in conventional configuration of direct torque control (DTC) while in the space vector pulse width modulated (SVPWM) DTC, the HC are switched to PI or PID controllers ...

Non‐Covalent Fluorine–Silica Anchoring of a Molecular Platinum(II) bis(NHC) Catalyst: Structure, Interface Control, and Hydrosilylation Activity

Chemistry – A European Journal, EarlyView.
A Pt(II) bis(NHC) complex is immobilized on mesoporous silica through directional F–Si interactions encoded in the ligand framework. Quantitative 19F{29Si} REDOR experiments and molecular dynamics simulations establish Å‐scale catalyst–support contacts and define the interfacial organization.

Scaling Up Molecular Electron Spin Qubits Around a Core‐Shell Quantum Dot

Chemistry – A European Journal, EarlyView.
Making assemblies of molecular nanomagnet (MNM) qubits is an essential step toward scalable quantum devices. Here, SH‐functionalized {Cr7Ni} antiferromagnetic rings with ability as MNM qubits were successfully grafted to the surface of fluorescent CdSe/ZnS quantum dots (QD).
