Hong-Li Liu, Ze-Tian Xu, Zhi-Yu Ma, Wen-Zhe Wei, Peng Hao, Wen-Hao Yuan, Huang Che, Fei-Hu Cheng, Zhi-Yuan Wang, Ke Deng, Ze-Huang Lu
2019 arXiv   pre-print
We perform quantum logic spectroscopy (QLS) on ^27Al^+ ion ^1S_0 - ^3P_1 transition, which is an important step toward the QLS based ^27Al^+ ion optical clock. As a precondition of QLS, both the stretch (STR) mode and the common (COM) mode of the ^27Al^+ and ^25Mg^+ ions pair are cooled to the vibrational ground state by Raman sideband cooling. The mean phonon number is measured to be 0.10(1) for the STR mode and 0.01(1) for the COM mode, respectively. The heating rate is evaluated to be 13(3)

Scattering-coded elastic meta-boundary [article]

Tianxi Jiang, Xinxin Liao, Hao Huang, Zhi-Ke Peng, Qingbo He
2021 arXiv   pre-print
Object localization through active elastic waves is a crucial technology, but generally requires a transducer array with complex hardware. Although computational sensing has been demonstrated to be able to overcome the short-comings of transducer array by merging artificially designed structures into sensing process, coding spatial elastic waves for active object identification is still a knowledge gap. Here we propose a scattering-coded elastic meta-boundary composed of randomly distributed

The multiple scattering effect of the meta-boundary introduces complexity into scattered fields to achieve a highly uncorrelated scattering coding of elastic waves, thereby eliminating the ambiguity of the object location information. We demonstrate that the locations of objects can be uniquely identified by using the scattering coding of our designed meta-boundary, delivering a design of meta-boundary touchscreen for human-machine interaction. The proposed scattering-coded meta-boundary opens up avenues for artificially designed boundaries with the capability of information coding and identification, and may provide important applications in wave sensing, such as structural monitoring, underwater detection, indoor localization, and biomedical imaging.

Adaptive Compact Attention For Few-shot Video-to-video Translation [article]

Risheng Huang, Li Shen, Xuan Wang, Cheng Lin, Hao-Zhi Huang
2020 arXiv   pre-print
This paper proposes an adaptive compact attention model for few-shot video-to-video translation. Existing works in this domain only use features from pixel-wise attention without considering the correlations among multiple reference images, which leads to heavy computation but limited performance. Therefore, we introduce a novel adaptive compact attention mechanism to efficiently extract contextual features jointly from multiple reference images, of which encoded view-dependent and

To further improve the reliability, in the inference phase, we also propose a novel method based on the Delaunay Triangulation algorithm to automatically select the resourceful references according to the input label. We extensively evaluate our method on a large-scale talking-head video dataset and a human dancing dataset; the experimental results show the superior performance of our method for producing photorealistic and temporally consistent videos, and considerable improvements over the state-of-the-art method.

CPOT: Channel Pruning via Optimal Transport [article]

Yucong Shen, Li Shen, Hao-Zhi Huang, Xuan Wang, Wei Liu
2020 arXiv   pre-print
Recent advances in deep neural networks (DNNs) lead to tremendously growing network parameters, making the deployments of DNNs on platforms with limited resources extremely difficult. Therefore, various pruning methods have been developed to compress the deep network architectures and accelerate the inference process. Most of the existing channel pruning methods discard the less important filters according to well-designed filter ranking criteria. However, due to the limited interpretability of
more » ... deep learning models, designing an appropriate ranking criterion to distinguish redundant filters is difficult. To address such a challenging issue, we propose a new technique of Channel Pruning via Optimal Transport, dubbed CPOT. Specifically, we locate the Wasserstein barycenter for channels of each layer in the deep models, which is the mean of a set of probability distributions under the optimal transport metric. Then, we prune the redundant information located by Wasserstein barycenters. At last, we empirically demonstrate that, for classification tasks, CPOT outperforms the state-of-the-art methods on pruning ResNet-20, ResNet-32, ResNet-56, and ResNet-110. Furthermore, we show that the proposed CPOT technique is good at compressing the StarGAN models by pruning in the more difficult case of image-to-image translation tasks.

Giant magnetoresistance ͑GMR͒ samples composed of TbCo/ Co/ Cu/ Co/ TbFeCo layers were fabricated with a GMR ratio of 4% and magnetization perpendicular to the film planes. A large coercivity ͑12 kOe͒ of the free layer ͑TbCo/ Co͒ guarantees the thermal stability at room temperature.

In recent years, the prosperous electric vehicle industry has contributed to the rapid development of lithium-ion batteries. However, the increase in the energy density of lithium-ion batteries has also created more pressing safety concerns. The emergence of a new flame-retardant material with the additive ethoxy (pentafluoro) cyclotriphosphazene can ameliorate the performance of lithium-ion batteries while ensuring their safety.

The study found that the heating rate is positively correlated with the onset temperature, peak temperature, and endset temperature of the endothermic peak. The flame-retardant modified polymer electrolyte for new lithium-ion batteries has better thermal stability than traditional lithium-ion battery electrolytes. Three non-isothermal methods (Kissinger; Kissinger–Akahira–Sunose; and Flynn–Wall–Ozawa) were also used to calculate the kinetic parameters based on the DSC experimental data. The apparent activation energy results of the three non-isothermal methods were averaged as 54.16 kJ/mol. The research results can provide valuable references for the selection and preparation of flame-retardant additives in lithium-ion batteries.

RPATTACK: Refined Patch Attack on General Object Detectors [article]

Hao Huang, Yongtao Wang, Zhaoyu Chen, Zhi Tang, Wenqiang Zhang, Kai-Kuang Ma
2021 arXiv   pre-print
Nowadays, general object detectors like YOLO and Faster R-CNN as well as their variants are widely exploited in many applications. Many works have revealed that these detectors are extremely vulnerable to adversarial patch attacks. The perturbed regions generated by previous patch-based attack works on object detectors are very large which are not necessary for attacking and perceptible for human eyes. To generate much less but more efficient perturbation, we propose a novel patch-based method

Firstly, we propose a patch selection and refining scheme to find the pixels which have the greatest importance for attack and remove the inconsequential perturbations gradually. Then, for a stable ensemble attack, we balance the gradients of detectors to avoid over-optimizing one of them during the training phase. Our RPAttack can achieve an amazing missed detection rate of 100% for both Yolo v4 and Faster R-CNN while only modifies 0.32% pixels on VOC 2007 test set. Our code is available at https://github.com/VDIGPKU/RPAttack.

The triglyceride concentration was determined by use of GPO-POD assay Kit. Results: Clozapine enhanced the expression level of ADD1/SREBP 1C mRNA and triglyceride concentration in the differentiated adipocytes. Clozapine significantly suppressed the expression levels of LPL mRNA and LPL protein with a dose-dependent and time-dependent manner, respectively. Conclusion: These data suggest that clozapine might play an important role in inducing adipocyte differentiation and the regulation of fat-cell derived factors. Crown

The RAND/UCLA appropriateness method (RAM) was applied to reach consensus among 15 worldly renowned experts and experienced clinicians. Results: This paper introduced the RAM procedure with its principles and applications and conducted a brief review of the resulting 2016 international consensus guidance for MG in comparison to clinical experience and management of Chinese MG patients. Conclusion: The 2016 international consensus guidance is a major contribution to the treatment and management of MG, providing an up-to-date expert consensus to assist clinicians around the world, especially those with limited experience and/or practice in countries/regions that have limited resources to develop local treatment guidelines. It is also an important contribution showing how RAM can help to develop consensus guidance for treatment of rare diseases based on scientific findings and expert experience.
