Human–machine interfaces(HMIs)are important windows for a human to communicate with the outside *** current HMI devices such as cellphones,tablets,and computers can be used to help people with aphasia for language ***,these conventional HMI devices are not friendly to some particular groups who also lose their abilities of physical movements like in the intensive care unit(ICU)or vegetative patients to realize language ***,we report a breath-driven triboelectric nanogenerator(TENG)acting as a HMI sensor for language expression through human breathing without voice controls or manual *** TENG is integrated within a mask and fabricated via a three-dimensional(3D)printing *** wearing the mask,the TENG can produce responsive electric signals corresponding to the airflow from breathing,which is capable of recognizing human breathing types with different intensities,lengths,and *** the basis of the breathing recognition ability,a breathing-based language expressing system is further developed through introducing the Morse code as a communication *** with conventional language expressing devices,this system can extract subjective information of a person from breathing behaviors and output corresponding language text,which is not relying on voices or physical *** research for the first time introduces the self-powered breathing-based language expressing method to the field of HMI technology by using a 3D printed TENG,and could make HMI interactions become more friendly and fascinating.

We investigate the level of galaxy assembly bias in the Sloan Digital Sky Survey (SDSS) main galaxy sample using ELUCID,a state-of-the-art constrained simulation that accurately reconstructed the initial density perturbations within the SDSS *** top of the ELUCID haloes,we develop an extended HOD model that includes the assembly bias of central and satellite galaxies,parameterized as Q_(cen)and Q_(sat),respectively,to predict a suite of one-and two-point *** particular,our fiducial constraint employs the probability distribution of the galaxy number counts measured on 8 h^(-1)Mpc scales N_8^(g) and the projected cross-correlation functions of quintiles of galaxies selected by N_(8)^(g) with our entire galaxy *** perform extensive tests of the efficacy of our method by fitting the same observables to mock data using both constrained and non-constrained *** discover that in many cases the level of cosmic variance between the two simulations can produce biased constraints that lead to an erroneous detection of galaxy assembly bias if the non-constrained simulation is *** applying our method to the SDSS data,the ELUCID reconstruction effectively removes an otherwise strong degeneracy between cosmic variance and galaxy assembly bias in SDSS,enabling us to derive an accurate and stringent constraint on the *** fiducial ELUCID constraint,for galaxies above a stellar mass threshold M_(*)=10^(10.2)h^(-2)M_(⊙),is Q_(cen)=-0.09±0.05 and Q_(sat)=0.09±0.10,indicating no evidence for a significant (>2σ) galaxy assembly bias in the local Universe probed by ***,our method provides a promising path to the robust modelling of the galaxy-halo connection within future surveys like DESI and PFS.

【目的】青山保护区是内蒙古罕山次生林北段的典型区域,了解内蒙古罕山次生林北段森林死亡梯度下植物多样性特征,为科学保护和利用森林自生植物群落,探索更适宜森林发展的植物群落提供依据。【方法】以青山保护区山杨Populus davidiana次生林为研究对象,采用样地调查法对不同死亡梯度林下植物组成进行调查,使用生物多样性指数和群落相似系数对植物组成及多样性的差异进行分析。【结果】内蒙古罕山次生林区北段不同死亡梯度下样地植物有45种,其中,乔木9种,灌木5种,草本31种,样地内的植物物种数从大到小依次为轻度死亡样地、重度死亡样地、中度死亡样地。不同样地内的Simpson和Shannon-Wiener指数从大到小依次为轻度死亡林分、重度死亡林分、中度死亡林分。中度死亡样地的丰富度指数和Pielou均匀度指数最高。通过主坐标分析(PCoA)发现轻度死亡样地内的群落差异最大。Sorensen群落相似系数(SI)为55%-61%,不同死亡梯度林分内共有种为13种,乔木层和灌木层对SI的差异影响并不大,草本多样性的降低效益明显,导致不同死亡梯度林分SI差异变大。总体而言,随着山杨死亡程度的增加植被组成差异性也不断增加。【结论】森林死亡导致植物多样性总体趋于降低,森林大量死亡抑制了草本植物多样性,但是促进了乔木和灌木的更新。研究区山杨优势度出现衰退,林内更新能否形成混交林有待进一步研究。

At present, the research of single-photon is a hot topic, it has been widely applied in quantum measurement, quantum entanglement and quantum information. In this paper, we have proposed a new single photon theory, which is the vector potential A rotation at the vertical motion direction of photon, it can produce the microscopic electric field and magnetic field, and they satisfy the Maxwell equations. We have calculated photon spin, momentum, energy, and found there are left-handed and right-handed photon. In addition, we study the multi-photon theory and the dynamics theory between photons interaction. On this basis, we have further given the compound structures of electron, proton, neutron, neutrino, π meson, dark matter with the photon structural theory, and calculated their mass, charge and spin.

从单目视觉中恢复深度信息是计算机视觉领域的经典问题,结合传统算法的深度学习方法是近年来的研究热点,但在神经网络的算法融合、参照物标定和应用场景上还有限制。提出了一种双路融合深度估计神经网络结构,分别基于深度与深度梯度的语义信息进行网络训练,对特征融合后再次训练得到最终的细节特征,并通过单次标定的方法解决真实参照物标定工作量大的问题。该网络结构能根据单张RGB图片推测出富有细节的深度信息,网络模型基于KITTI的深度图数据集训练,实验包括KITTI测试集和部分实际场景图集,结果表明该方法在深度信息细节的重建上优于对比深度估计方案,在大视场场景下的鲁棒性优良。
