Thermometric detectors are crucial in evaluating the condition of target objects spanning from environments to the human body.Optical-based thermal sensing tools have received extensive attention,in which the photon upconversion process with low autofluorescence and high tissue penetration depth is considered as a competent method for temperature monitoring,particularly in biomedical fields.Here,we present an optoelectronic thermometer via infrared-to-visible upconversion,accomplished by integrated light receiving and emission devices.Fully fabricated thin-film,microscale devices present temperature-dependent light emission with an intensity change of 1.5%℃^(-1) and a spectral shift of 0.18 nm℃^(-1).The sensing mechanism is systematically characterized and ascribed to temperature dependent optoelectronic properties of the semiconductor band structure and the circuit operation condition.Patterned device arrays showcase the capability for spatially resolved temperature mapping.Finally,in vitro and in vivo experiments implemented with integrated fiber-optic sensors demonstrate real-time thermal detection of dynamic human activity and in the deep brain of animals,respectively.

Living-cell imaging demands high specificity,sensitivity,and minimal background interference to the targets of interest.However,developing a desirable imaging probe that can possess all the above features is still challenging.The bioorthogonal surface-enhanced Raman scattering(SERS) imaging has been recently emerged through utilizing Raman reporters with characteristic peaks in Raman-silent region of cells(1800-2800 cm^(-1)),which opens a revolutionary avenue for living-cell imaging with multiplexing capability.In this review,we focus on the recent advances in the technology development and the biological and biomedical applications of the living-cell bioorthogonal SERS imaging technique.After introduction of fundamental principles for bioorthogonal tag or label,we present applications for visualization of various intracellular components and environment including proteins,nucleic acids,lipids,pH and hypoxia,even for cancer diagnosis in tissue samples.Then,various bioorthogonal SERS imaging-guided thera py strategies have been discussed such as photothera py and surge ry.In conclusion,this strategy has great potential to be a flexible and robust tool for visualization detection and diseases diagnosis.

Effective short-term prediction of regional voltage load is of great significance to the implementation of energy saving and emission reduction policies in China.Accurate prediction of real-time demand voltage can reduce power waste and carbon emissions,make outstanding contributions to delaying global climate warming,and is conducive to global environmental protection and sustainable development.On the short-term load forecasting of power system,a variant model of RNN-LSTM is tested in this paper.It effectively solves the problem of gradient explosion and disappearance caused by large amount of data input in classical RNN.On the basis of this model,optimization experiments are carried out under different super parameters to achieve better prediction results.The experimental results show that the accuracy of test set reaches 99.8%,which proves that the method proposed in this paper has certain reference value.

经典的边缘提取算法在实际应用中由于成像质量不高而被限制,基于鬼成像的边缘提取技术可对待测物实现高信噪比的边缘成像。基于此,提出一种基于Scharr算子的计算鬼成像边缘提取技术。Scharr算子具有低的计算复杂度和较小的计算量,可以更有效处理图像,将Scharr算子作用于散斑生成一组全新的散斑函数,对于Scharr算子模板作用于散斑移动中存在的边缘提取结果在某方向信息缺失的问题进行改进,对算子模板正负进行转换,生成新的算子模板,将新生成的算子模板运用于移动散斑使其生成新的照明散斑,从而实现对边缘提取结果各方向信息的补全。并根据计算鬼成像基本方法在理论上和实验上对未知图像的边缘进行提取,仿真与实验结果表明,所提方法可以获得完整清晰的待测物边缘。

First,the cellular automaton was used to simulate a"T"junction,and the correlation analysis was performed by combining the traffic pattern and the corresponding data to obtain the reason for the inaccurate prediction time of the navigation software.The collected data is preprocessed to obtain the driving time of multiple road vehicles in a week,and this is used as the influencing factor.Reuse the collected information:the length of the intersection,the average speed of real-time vehicles at the intersection,and the length of the intersection.The first two processes of the three pre-processing processes are considered together to obtain a time-dependent factor.The correlation factors and the duration of the intersections are used to predict the results of neural network training.Based on the analysis and prediction of the data,the causes of urban traffic congestion are analyzed,and measures to reduce urban congestion are proposed.
