57038 本文的TSCF模型有闭式解,采用共轭梯度下降法迭代逼近模型的最优解,且优化过程利用循环矩阵性质转化到傅里叶域快速求解,有效降低计算大型矩阵的代价.本文的TSCF算法跟踪结果在TB100公开数据库上显示,距离精度较基准BACF算法提升了5.5%,成功率曲线图线下面积(AUC)提升了4. 3%,纯手工特征跟踪性能在TB100数据库上100个视频的跟踪距离精度达到0.879, AUC为0.664,结果展示本文的TSCF算法在遇到诸如短时间遮挡和面内旋转或面外旋转等挑战性问题时具有一定的鲁棒性和有效性. The temporal consistency constraint smooths the multi?channel correlation filter in the time series, and the spatial consistency constraint smooths the multi-channel correlation filter in spatial distribution, thus making the energy distribution more uniform of the correlation filter learned. In this paper, the TSCF model has closed solutions and the conjugate gradient descent method is used to approximate the optimal solution of a system of closed solutions. The optimization process can then be transformed into the Fourier domain using cyclic matrix properties to quickly obtain a solution, which effectively reduces the cost of calculating large matrices. In this paper, our TSCF algorithm increases distance precision by 5. 5% and raises the AUC by 4. 3% compared to the baseline BACF algorithm on the TB100 public database. The distance precision achieves 0. 879 and the AUC reaches 0. 663 on the TB100 database making use of only hand-crafted features. The TSCF algorithm proposed in this paper can be applied to challenging conditions such as short time occlusion, out-of-plane rotation, in-plane rotation, and so on, thus demonstrating its robustness and effectiveness.
57039 为探究红荧烯（Rubrene）内部的单重态激子分裂（S1+S0→T1+T1, STT）和发光过程的微观机制,本文选用具有强自旋轨道耦合（spin-orbit coupling, SOC）且发射绿光的磷光材料Ir（ppy）3,以不同比例混入到发射橙光的Rubrene薄膜中制备了一系列发光器件,并在不同温度和电流下测量了器件的电致发光磁效应（magneto-electroluminescence, MEL）和电流–发光（I-B）曲线.实验发现:室温下不同混入比例的发光器件,其MEL线型均表现为磁场调制的STT指纹式特征曲线,但MEL幅值随混入比例的增加却表现出先增加后减小的特性,而其发光强度则表现为单调增加的特点,这与常规Rubrene掺杂器件（如mCP:y%Rubrene）随浓度增大其STT增强但发光减弱的结果不同. To explore the microscopic mechanism of singlet exciton splitting (S1 + S0 → T1 + T1, STT) and luminescence in Rubrene, a phosphorescent material Ir(ppy)3 with strong spin-orbit coupling (SOC) and green emission was selected and mixed into Rubrene thin films with different proportions to fabricate a series of lumi?nescent devices. By measuring the magneto-electroluminescence (MEL) and current-luminescence (I-B) curves of the devices under different temperatures and currents, we found that the MEL profiles of light-emitting devices with different mixing ratios at room temperature show an STT fingerprint characteristic curve of magnetic field modulation.
57040 通过对Ir（ppy）3的单、三重态激子能级和发射谱以及Rubrene吸收谱的分析可知,器件中除了Rubrene分子间距会影响STT过程的强弱外,还包括由Ir（ppy）3强的SOC导致的激子间的系间穿越（intersystem crossing, ISC）和Ir（ppy）3的T1激子与Rubrene的S1激子间的能量传递（energy transfer, ET）过程,这3种微观机制的共同作用导致了器件MEL和发光的复杂变化,且电流密度的大小和器件工作温度的高低对它们还有较好的调控作用. MEL amplitude first increases and then decreases with increased mixing ratio, whereas lumines?cence intensity increases monotonously. This is different from conventional Rubrene doped devices (such as mCP: y%Rubrene) which show STT increases with increasing concentration but with decreasing luminescence . By an?alyzing the singlet and triplet energy levels and emission spectra of Ir(ppy)3 and absorption spectra of Rubrene, it can be seen that aside from Rubrene’s molecular space’s influence on the STT process, intersystem crossing (ISC) caused by the strong SOC of Ir(ppy)3 and energy transfer processes between the T1 exciton of Ir(ppy)3 and the S1 exciton of Rubrene are also included in the devices.
57041 显然,本研究有助于深入理解基于红荧烯光电器件的微观过程及其演化机制. The combined action of these three micro-mechanisms leads complex MEL and luminescence changes in the device, and the device’s current density and working temperature also have a good regulatory effect on them. Obviously, this study helps with understanding of the microscopic process and its evolution mechanism based on Rubrene optoelectronic devices.

57046 不同于一般图像分割问题,砂岩薄片图像中包含大量矿物颗粒,且相邻颗粒之间边界模糊,通用的图像分割方法难以适用. Unlike segmentation of ordinary images, thin section images of sandstone contain many mineral grainsand the differences among adjacent grains are usually ambiguous, which makes conventional segmentation methodsdifficult to apply.
