A Reconfigurable Memristive Spiking Neuron Enabling Advanced Neuromorphic Computing
Advanced Science, EarlyView.Pek Jun Tiw and co‐workers develop a reconfigurable memristive neuron that can exhibit four spiking behaviors with freely tunable spike train parameters. The neuron supports multiplexed spike encoding of multiple pieces of information. It also supports advanced neural network strategies, such as neural heterogeneity and dynamic mode switching ...

Macrophage Trogocytosis of Tumor Cells Drives the Immunosuppression of Tumor Microenvironment
Advanced Science, EarlyView.Trogocytosis efficiency varies significantly among different tumor cells and is inversely related to their cortical stiffness; this efficiency dictates the extent of immunosuppression via upregulation of CXCL5 and Arg‐1, ultimately driving CD8+T cell exhaustion and tumor escape.

TSP with neighborhoods of varying size [PDF]
Journal of Algorithms, 2002 Summary: In TSP with Neighborhoods (TSPN) we are given a collection \(\mathcal S\) of regions in the plane, called neighborhoods, and we seek the shortest tour that visits all neighborhoods. Until now constant-factor approximation algorithms have been known only for cases where the neighborhoods are of approximately the same size.

A modified algorithm of Hopfield network to solve TSP(Hopfield网络解TSP的改进算法)
Zhejiang Daxue xuebao. Lixue ban, 2001 针对Hopfield网络解旅行商问题（TSP)经常出现无效解和局部优化解，本文给出置换矩阵的满足一定条件的元素Vxi作为初始值，以便得到有效解.此外，还利用较大的步长所产生的误差和对当前解必须优于或等于已有解的要求，使计算结果能从局部优化解达到全局最优解.大量的模拟实例表明，该算法具有迭代次数少，收敛速度快，易获得有效解和全局最优解等优点.
