Designing Few-layer Graphene Schottky Contact Solar Cell: Theoretical Efficiency Limits and Parametric Optimization
Xin Zhang, Jicheng Wang, Yee Sin Ang +1
We theoretically study the efficiency limits and performance characteristics of few-layer graphene-semiconductor solar cells (FGSCs) based on a Schottky contact device structure. W…
FLEAM: A Federated Learning Empowered Architecture to Mitigate DDoS in Industrial IoT
J. Li, L. Lyu, X. Liu +2
The distributed denial of service (DDoS) attack is detrimental to the industrial Internet of things (IIoT) as it triggers severe resource starvation on networked objects. Recent dy…
Robust single-qubit gates by composite pulses in three-level systems
Zhi-Cheng Shi, Hai-Ning Wu, Li-Tuo Shen +3
Composite pulses are an efficient tool for robust quantum control. In this work, we derive the form of the composite pulse sequence to implement robust single-qubit gates in a thre…
A Homotopy Coordinate Descent Optimization Method for -Norm Regularized Least Square Problem
Zhenzhen Sun, Yuanlong Yu
This paper proposes a homotopy coordinate descent (HCD) method to solve the -norm regularized least square (-LS) problem for compressed sensing, which combine the homotop…
Two-level systems with periodic -step driving fields: Exact dynamics and quantum state manipulations
Zhi-Cheng Shi, Ye-Hong Chen, Wei Qin +4
In this work, we derive exact solutions of a dynamical equation, which can represent all two-level Hermitian systems driven by periodic -step driving fields. For different physi…
Brain Tumor Segmentation Network Using Attention-based Fusion and Spatial Relationship Constraint
Chenyu Liu, Wangbin Ding, Lei Li +4
Delineating the brain tumor from magnetic resonance (MR) images is critical for the treatment of gliomas. However, automatic delineation is challenging due to the complex appearanc…
