Podcast: Gender balance in nuclear, and the EU's Net Zero Industry Act
核能领域 净零排放法案 Gender balance
2023/4/6
An international survey has highlighted the need for a better gender balance in the nuclear sector, but how to achieve it? That's one of the issues discussed with Corhyn Parr, CEO of Nuclear Waste Ser...
The European Commission (EC) has proposed the Net-Zero Industry Act (NZIA) to scale up manufacturing of clean technologies in the EU and make sure it is well-equipped for the clean-energy transition. ...

北京大学物理学院 吴孝松 课题组 PNAS 狄拉克 半金属 ZrTe5中spin zero现象
2018/9/19
北京大学物理学院俞大鹏院士领导的“纳米结构与低维物理”团队的吴孝松研究组通过研究三维狄拉克半金属材料ZrTe5中量子振荡随磁场倾角的演化，在拓扑材料中第一次观察到了spin zero现象。这一现象带来的振荡相位反转，表明广泛使用的确定贝里相的实验方法，在某些条件下会得出错误结论。

Exploring Semantic Inter-class Relationships Zero-shot Action Recognition
2016/1/22
Automatically recognizing a large number of action cat-egories from videos is of significant importance for video understanding. Most existing works focused on the design of more discriminative featur...
Study on Copyright Authentication of GIS Vector Data Based on Zero-Watermarking
GIS Copyright Authentication Digital Product Vector Data Zero-watermarking Hash
2015/12/18
GIS vector data is closely linked with the development of social economy and national defense, which is of high production cost and high precision, so the copyright protection of GIS vector data means...
REGISTERING INTERFEROMETRIC SAR IMAGES USING MARRHILDRETH ZERO-CROSSINGS
Registration SAR Edge Image Digital
2015/6/1
Leberl (Leberl, 1990) proposed an edge-based algorithm for finding matching pairs of points in SAR images. In this paper, we show that the algorithm can be used to register interferometric SAR images ...

Infrastructure disaster risk assessment seeks to estimate the probability of a given customer or area losing service during a disaster, sometimes in conjunction with estimating the duration of each ou...
Impact of chirp on spectral recoil of solitons in a defect-core photonic crystal fiber with two zero-dispersion wavelengths
Pulse propagation temporal solitons Photonic crystal fibers
2015/5/22
Increasing input chirp decelerates (accelerates) the spectral recoiling process across a negative dispersion slope for pulses experiencing normal (anomalous) dispersion. A realistic defect-core photon...
Tolerance to nonlinearity of 40 Gb/s BPSK-based coherent solution over legacy systems based on non-zero dispersion- shifted fibers
coherent communication optical communication
2015/5/22
We experimentally assess the performance of coherent PDM-BPSK at 40Gb/s over non-zero dispersion-shifted fiber. The BPSK-based solution is found about 7.5dB more robust than the QPSK-based solution ag...
