Immunotherapy has become the fourth cancer therapy after surgery, chemotherapy, and radiotherapy. In particular, immune checkpoint inhibitors are proved to be unprecedentedly in increasing the overall survival rates of patients with refractory cancers, such as advanced melanoma, non-small cell lung cancer, and renal cell carcinoma. However, inhibitor therapies are only effective in a small proportion of patients with problems, such as side effects and high costs. Therefore, doctors urgently need reliable predictive biomarkers for checkpoint inhibitor therapies to choose the optimal therapies. Here, we review the biomarkers that can serve as potential predictors of the outcomes of immune checkpoint inhibitor treatment, including tumor-specific profiles and tumor microenvironment evaluation and other factors.

飞航导弹的飞行主要是通过姿态稳定与调节来实现的。通过以小扰动模型为基础的导弹动力学特性分析,建立了导弹姿态控制回路的串级控制结构,并且以离散模型作为基于递推最小二乘法的自适应预测控制的被控对象,把原先响应较慢的质心控制转换为反应较快而且精度高的弹道角控制。根据导弹的特性,在姿态内回路采用广义预测控制,在弹道外回路采用一种积分形式的预测控制。在参考信号上,实现了质心指令到弹道指令的有效变换,为高精度小超调跟踪奠定了基础。这种方法实现了姿态参考信号与导引指令的统一,姿态控制与质心控制的统一,充分降低了对气动等数据的精度要求,参数选择简单。数值仿真结果说明了这种方法的有效性;提出了进一步的研究方向。

测量柔性有机显示器件对水蒸气的高阻隔性,是确保其可靠性所面临的重大工程挑战。一方面,目前缺少10-6 g·m-2·d-1量级的水渗透率测试手段;另一方面,目前也没有标准的超阻隔样品用于渗透率测量的校准。为了对渗透过超阻隔材料的痕量水蒸气流量进行高灵敏、短周期测量,本文将渗透模型集成至基于渗透分子动态积累、检测和抽空的高灵敏质谱测量中,从而开发出了一种具有预测功能的测量仪器。通过使用标准聚合物样品进行校准,确保了测量结果的可靠性。校准后的水蒸气渗透检测下限在10-7g·m-2·d-1量级,满足超阻隔渗透的测量灵敏度要求。本文利用渗透实验数据对所开发的预测渗透模型进行了测试评估,使得利用非稳态数据预测稳态渗透率成为可能,实现在更短的时间内有效开展超阻隔测量。

针对暖通空调HVAC系统中由于存在高度非线性、时变特征以及扰动和不确定性等因素而难以控制的特点,提出基于Takagi-Sugeno(T-S)模糊模型的预测函数控制器设计方法。该方法通过最小二乘辨识算法建立系统的模糊T-S模型,然后基于模糊全局线性化预测模型,采用预测函数控制算法设计系统控制律。仿真实验结果表明该算法是一种跟踪性能好、鲁棒性强的有效控制方法。与常规的PID控制器相比,该方法具有超调量小、调整时间短等优良的动态性能。

The zinc oxide rotary kiln, as an essential piece of equipment in the zinc smelting industrial process, is presenting new challenges in process control. China's strategy of achieving a carbon peak and carbon neutrality is putting new demands on the industry, including green production and the use of fewer resources; thus, traditional stability control is no longer suitable for multi-objective control tasks. Although researchers have revealed the principle of the rotary kiln and set up computational fluid dynamics (CFD) simulation models to study its dynamics, these models cannot be directly applied to process control due to their high computational complexity. To address these issues, this paper proposes a multi-objective adaptive optimization model predictive control (MAO-MPC) method based on sparse identification. More specifically, with a large amount of data collected from a CFD model, a sparse regression problem is first formulated and solved to obtain a reduction model. Then, a two-layered control framework including real-time optimization (RTO) and model predictive control (MPC) is designed. In the RTO layer, an optimization problem with the goal of achieving optimal operation performance and the lowest possible resource consumption is set up. By solving the optimization problem in real time, a suitable setting value is sent to the MPC layer to ensure that the zinc oxide rotary kiln always functions in an optimal state. Our experiments show the strength and reliability of the proposed method, which reduces the usage of coal while maintaining high profits.
