5Manipulation of invisible cloaking in PT-symmetric thermoacoustic dimer显示文摘Making the propagation of sound waves immune to interference from obstacles with high transmission efficiency is a long-term pursuit in acoustic science and engineering.Recent proposal pointed out that perfect transmission through obstacles can be achieved by deploying a bulky gain-loss distribution in parity-time(PT)symmetry.Here we demonstrate a modified methodology to achieve the extraordinary physical property of acoustic cloaking accompanied by perfect transmission at the exceptional points(EPs).Systematically probing reveals two complementary solutions of EPs corresponding to acoustic cloaking,in the system composed of an equivalent medium slab sandwiched by a pair of PT-symmetric admittance metasurfaces.To model the crucial acoustic gains that are not present in nature,we employ actively controlled ultra-thin carbon nanotube dimer films to mimic admittance metasurfaces perfectly via thermoacoustic effect,and manipulate acoustic cloaking over a wide frequency band in experiments.This divergent strategy releases restrictions on the operating frequency,shape and size of the obstacle,which can be applied to acoustic sensing,directional imaging,and other related wave disciplines.Haixiao Zhang Bolun Hu Wei Xiong Ying Cheng Xiaojun Liu 2023Science China(Physics,Mechanics & Astronomy)2023,66,12:0
6Comparing GWAS and Brain Structure-Specific Gene Expression Profiles Identifies Psychiatric Disorder-Related Brain Structures at Different Developmental Stages显示文摘Dear Editor,Psychiatric disorders are a group of mental disorders characterized by psychological or behavioral disabilities.Losing of the ability to work and assuming the extensive cost of long-term treatment,patients with psychiatric disorders are forced to support a heavy financial and medical burden.The growth and development of brain structures are dynamic,and different brain structures have major and specific functions to control behavior and performance.Xin Qi Cuiyan Wu Yanan Du Shiqiang Cheng Yan Wen Mei Ma Chujun Liang Li Liu Bolun Cheng Lu Zhang Ping Li Feng Zhang 2020Neuroscience Bulletin2020,36,9:0
7A Phrase Topic Model Based on Distributed Representation显示文摘Traditional topic models have been widely used for analyzing semantic topics from electronic documents.However,the obvious defects of topic words acquired by them are poor in readability and consistency.Only the domain experts are possible to guess their meaning.In fact,phrases are the main unit for people to express semantics.This paper presents a Distributed Representation-Phrase Latent Dirichlet Allocation(DR-Phrase LDA)which is a phrase topic model.Specifically,we reasonably enhance the semantic information of phrases via distributed representation in this model.The experimental results show the topics quality acquired by our model is more readable and consistent than other similar topic models.Jialin Ma Jieyi Cheng Lin Zhang Lei Zhou Bolun Chen 2020Computers, Materials & Continua2020,,7:0
