Weakened and Irregular Miocene Climate Response to Orbital Forcing compared to the modern day

Yurui Zhang, Jilin Wei, Zhen Li, Nan Dai et autres

Abstract. Orbital forcing is a well-established driver of Pleistocene glacial-interglacial cycles, but its role in warmer climates remains less clear. Using climate model simulation, we assess temperature response to maximum and minimum boreal summer insolation during the Miocene and pre-industrial (PI) time. …

VICO: Visual-Inertial Continuous-Time Odometry Based on Generalized Hermite Spline

Hao-Yu Qi, Zhen Li, Haikuo Liu, Xiangdong Liu et autres

Continuous-time simultaneous localization and mapping (SLAM) facilitates the seamless fusion of asynchronous and high update-rate sensors. The traditional continuous-time parameterizaton adopts the cumulative$B$-splines, causing the complexity in implementation and abstraction of control points. To address these issues, this paper proposes a continuous-time …

Adaptive Differential Evolution Integration: Algorithm Development and Application to Inverse Heat Conduction

Zhibiao Zhao, Zhen Li, Hao Luan, Yan Shi

In response to the limitations observed in existing single intelligent optimization algorithms, particularly their shortcomings in their global search capability and population diversity, we propose the Adaptive Differential Evolution Integral (ADEI) algorithm. Drawing inspiration from the collective behaviors observed in social organisms, …

Reducing dose sensitivity in high-numerical-aperture extreme ultraviolet lithography using an innovative source optimization method

Zhaoxuan Li, Miao Yuan, Zhen Li, Yang He et autres

Errors such as illumination non-uniformity and system drift during scanning can lead to unpredictable dose non-uniformity and degrade the imaging performance across the wafer. This paper proposes a novel, to our knowledge, source optimization (SO) method for high-numerical-aperture extreme ultraviolet lithography (high-NA …

Fast optical proximity correction method adopting an iterative threshold algorithm of log-sum regularization compressive sensing

Zhen Li, Yanqiu Li, Miao Yuan, Yang He et autres

Mask optimization is the key step of the advanced technology node in the VLSI manufacturing process. As one of the most representative techniques, optical proximity correction (OPC) is a resolution enhancement technique widely used in lithography. Striking the right balance between lithographic …

Methionine intervention induces PD-L1 expression to enhance the immune checkpoint therapy response in MTAP-deleted osteosarcoma

Haoran Mu, Qí Zhāng, Dongqing Zuo, Jinzeng Wang et autres

Osteosarcoma (OS), a malignant bone tumor with limited treatment options, exhibits low sensitivity to immune checkpoint therapy (ICT). Through genomics and transcriptomics analyses, we identify a subgroup of OS with methylthioadenosine phosphorylase (MTAP) deletion, which contributes to ICT resistance, leading to a …
