Josephson junctions with negative second harmonic in the current-phase relation: properties of novel varphi-junctions

, 2007
Several recent experiments revealed a change of the sign of the first harmonic in the current-phase relation of Josephson junctions (JJ) based on novel superconductors, e.g., d-wave based or JJ with ferromagnetic barrier.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

An Adaptive Harmonics Suppression Strategy Using a Proportional Multi-Resonant Controller Based on Generalized Frequency Selector for PMSM

Actuators
In permanent magnet synchronous motor (PMSM) drive systems, the nonlinearity of the inverter and non-sinusoidal nature of back EMF generate harmonics in the stator current, resulting in torque ripple and reduced motor efficiency.

Voltage and Current Excitation for Time-Harmonic Eddy-Current Problems [PDF]

SIAM Journal on Applied Mathematics, 2008
We give a systematic presentation of voltage or current intensity excitation for time-harmonic eddy-current problems. The key point of our approach resides in a suitable power law that permits us to understand the role of voltage excitation. We also shed light on the influence of the boundary conditions on the proposed formulations.

Risk Prediction Models for Recurrence After Curative Treatment of Early‐Stage or Locally Advanced Lung Cancer: A Systematic Review

Aging and Cancer, EarlyView.
This systematic review synthesizes prognostic models for survival and recurrence in resected non‐small cell lung cancer. While many models demonstrate moderate to good discrimination, few are externally validated and reporting quality is variable, limiting clinical applicability and highlighting the need for robust, transparent model development ...

Current-Harmonic-Based Active Damping Strategy

Zhongguo dianli, 2023
The voltage-harmonic-based active damping control (VHBAD) can improve the adaptability of the converter to the weak grid, but it will weaken the suppression ability of background harmonic voltage disturbance and affect the quality of grid-connected ...
