title: Long Time Series Radiometric Calibration of Suomi-NPP VIIRS Based on Surface Hyperspectral BRDF Model
title: 基于场地BRDF模型的Suomi-NPP VIIRS长时序定标

description: In order to improve the calibration frequency of optical satellite remote sensors, a high-frequency absolute radiometric calibration method based on the surface hyperspectral bidirectional reflectance distribution function (BRDF) model is proposed, and the long time series absolute radiometric calibration of Suomi-national polar orbiting partnership spacecraft (Suomi-NPP) visible infrared imaging radiometer suite(VIIRS)is realized. The principle of the absolute radiometric calibration method based on the surface hyperspectral BRDF model is introduced. In April 2018 and August 2018, the surface directional reflectance of the Dunhuang test site was measured by the hyperspectral BRDF manual measurement system, and the hyperspectral BRDF model parameters of the Dunhuang site were inversed based on the semi-empirical kernel-driven model. Based on the BRDF models the apparent reflectance of VIIRS M1-M11 bands in the whole year of 2018 was calculated, and compared with the satellite-observed ones. The results show that the effective calibration number of Suomi NPP VIIRS is 51 in 2018 the relative deviation of model-calculated apparent reflectance and satellite-observed ones of the M1-M7 bands is less than 3.23%The proposed method can effectively improve the calibration frequency of satellite and track the change of radiometric characteristics of the load in time.

title: Singularity avoidance for manipulators with spherical wrists using the approximate damped reciprocal algorithm
title: 基于逼近阻尼倒数的球形手腕机械臂奇异点规避

description: Due to the loss of freedom, the stability and tracking ability of the manipulator around the singularity become worse. This article aims at improving the accuracy of the manipulator and ensuring the stability of the system with the damped reciprocal method. Firstly, the singularities are separated into forearm and wrist singularities to obtain the singular factors of the manipulator respectively. Secondly, a new mathematical function of the approximate damped reciprocal of the singular factor is proposed. Thirdly, the singularities are avoided by modifying the Jacobian matrixes of the manipulator with the approximate damped reciprocal algorithm. Finally, the effectiveness and the stability of the system are proved by the simulations on a manipulator with the spherical wrist. The simulation results prove that this method can largely improve the accuracy of the end-effector and can ensure the stability of the system around the singular region.

title: Initial results and designs of dual-filter and plenoptic imaging for high-temperature plasmas
title: Initial results and designs of dual-filter and plenoptic imaging for high-temperature plasmas

description: Mass injection has found new applications in magnetic fusion including edge-localized-mode control. Better understanding of injected-mass-plasma interactions requires spatially and temporally resolved diagnostics that can characterize the dynamics of the mass interactions with plasmas. Fast imaging can be used to characterize the ionization dynamics such as the propagation of the ionization front, which moves at the thermal sound or higher speed, and mixing of the neutral atoms with the ambient plasma. Multi-wavelength spectral imaging is promising since different parts of the plasma give different spectral signatures. Here we describe a dual-spectral imaging technique based on a monochromatic camera sensor and filters with two passing optical wavelengths. The method is shown to improve image contrast, and it compares favorably with alternatives such as color cameras and methods using a filter wheel. Further improvements through relative filter area ratios and plenoptic imaging are possible. The initial results from EAST and plenoptic imaging are also included.

title: Chemotherapy-induced pyroptosis is mediated by BAK/BAX-caspase-3-GSDME pathway and inhibited by 2-bromopalmitate
title: Chemotherapy-induced pyroptosis is mediated by BAK/BAX-caspase-3-GSDME pathway and inhibited by 2-bromopalmitate

description: Many chemotherapy treatments induce apoptosis or pyroptosis through BAK/BAX-dependent mitochondrial pathway. BAK/BAX activation causes the mitochondrial outer membrane permeabilization (MOMP), which induces the activation of pro-apoptotic caspase cascade. GSDME cleavage by the pro-apoptotic caspases determines whether chemotherapy drug treatments induce apoptosis or pyroptosis, however, its regulation mechanisms are not clear. In this study, we showed that TNFα+CHX and navitoclax-induced cancer cell pyroptosis through a BAK/BAX-caspase-3-GSDME signaling pathway. GSDME knockdown inhibited the pyroptosis, suggesting the essential role of GSDME in this process. Interestingly, GSDME was found to be palmitoylated on its C-terminal (GSDME-C) during chemotherapy-induced pyroptosis, while 2-bromopalmitate (2-BP) could inhibit the GSDME-C palmitoylation and chemotherapy-induced pyroptosis. Mutation of palmitoylation sites on GSDME also diminished the pyroptosis induced by chemotherapy drugs. Moreover, 2-BP treatment increased the interaction between GSDME-C and GSDME-N, providing a potential mechanism of this function. Further studies indicated several ZDHHC proteins including ZDHHC-2,7,11,15 could interact with and palmitoylate GSDME. Our findings offered new targets to achieve the transformation between chemotherapy-induced pyroptosis and apoptosis.

title: Metal Oxide/Graphene/Metal Sandwich Structure for Efficient Photoelectrochemical Water Oxidation
title: Metal Oxide/Graphene/Metal Sandwich Structure for Efficient Photoelectrochemical Water Oxidation

description: Single-layer graphene (SLG) has drawn considerable interest in photoelectrochemical (PEC) cells due to its atomically flat pinhole-free structure and remarkable in-plane carrier mobility. It is challenging, however, to obtain efficient SLG-modified photoelectrodes for PEC water splitting mainly due to the inefficient charge transfer interface. Here we construct a transition metal oxide/SLG/transition metal sandwich structure modified n-Si-based model photoanode to regulate the interfacial charge transfer behavior for enhanced PEC water oxidation performance. In this sandwich configuration, SLG tailors the morphology, structure, and work function properties of surface metal electrocatalysts to obtain both higher thermodynamic photovoltage and faster kinetical charge transfer at the semiconductor/electrolyte interface. In addition, SLG promotes the surface catalytic reaction as an effective charge trap and storage layer. Our work provides a new structural design to engineer the SLG interfacial properties for high-performance energy conversion devices.
