The term 'orocline' was first proposed by Carey [1] to describe the structure as 'an orogenic system which has been flexed in plane to a horse-shoe or elbow shape';it usually emphasizes that a previous straight mountain belt or tectonic units have been bended *** the orocline has been used to describe any curved mountain belt regardless of its original shape [2].

PPG-CNTs-nZVI bead was synthesized by polyvinyl alcohol, pumice, carbon nanotube, and guar gum-nanoscale zero-valent iron to be applied on simultaneously removal of polycyclic aromatic hydrocarbons (PAHs;phenanthrene) and heavy metals (Pb2+) via adsorption. The individual and simultaneous removal efficiency of phenanthrene and Pb2+ using the PPG-CNTs-nZVI beads was evaluated with a range of initial concentrations of these two pollutants. The kinetics and isotherms of phenanthrene and Pb2+ adsorption by the PPG-CNTs-nZVI beads were also determined. The PPG-CNTs-nZVI beads show reasonably high phenanthrene adsorption capacities (up to 0.16 mg/g), and they absorbed 85% of the phenanthrene (initial concentration 0.5 mg/L) in 30 min. High Pb2+ adsorption capabilities were also demonstrated by the PPG-CNTs-nZVI beads (up to 11.6 mg/g). The adsorption fits the Langmuir model better than the Freundlich model. The adsorption still remained stable with various ionic strength circumstances and a wide pH range (2–5). Additionally, the co-adsorption of phenanthrene and Pb2+ by the PPG-CNTs-nZVI beads resulted in synergistic effects. Particularly, phenanthrene-Pb2+ complex formation via π–cation interactions demonstrated a greater affinity than phenanthrene or Pb2+ alone. The present findings suggest that PPG-CNTs-nZVI beads may be effective sorbents for the simultaneous removal of PAHs and heavy metals from contaminated waters. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

In recent years, the complexity of semiconductor manufacturing processes has increased, leading to a growing need for the high-precision optimization of device structures. For example, in batch-type wet etching devices, the flow of chemical liquids within the process bath can vary depending on the device structure, causing variations in the etching state of the wafer. This issue is addressed using a feedback mechanism that iteratively adjusts the device structure based on the results of an etching experiment, thereby achieving more uniform etching conditions. However, this approach requires a large number of trial experiments. In the fabrication process of 3D flash memories, word-line formation in the silicon substrate requires precise control of the silicon concentration in the etching solution. However, this concentration can fluctuate due to the dissolution of the SiN film during the etching process. This fluctuation may cause various problems. This study introduces an innovative method utilizing multi-objective Bayesian optimization to derive optimal wet etching bath design parameters; this method is informed by image and physical-quantity data from fluid dynamics simulations [1]. This approach is validated through simulation experiments, whose results are used to identify the best possible wet etching bath designs effectively.

Coughing as the main symptom of a chronic cough is a persistent respiratory disease that poses a substantial challenge to Western medicine and traditional Chinese medicine (TCM). The Large Intestine and Lung are intimately related, impacting each other's pathology and physiology, according to TCM theory. This complex interaction emphasizes how crucial it is to treat both organs at the same time while treating cough to support gut health. This viewpoint is further supported by current research, which demonstrates the connections between the Large Intestine and the Lung through a variety of pathways, including neurological pathways, mucosal immune system modulation, gas exchange dynamics, and microbiota composition. To clarify the mechanisms and practical applications of treating chronic cough by concurrently targeting the Lung and Intestine in TCM, this paper merges ideas from TCM theory and empirical research in Western medicine. This provides insightful information for efficiently managing chronic cough.

Five types commercial vehicles equipped with advanced emergency braking pedestrian system (AEBS_Ped) from different Chinese manufacturers was tested and evaluated in accordance with the traffic industry standard JT/T 1242-2019 performance requirements and test procedures for commercial vehicle AEBS_Ped. The test results show that the braking efficiency of the system is relevant to the time to collision (TTC) and the execution strategy of the braking system. The braking stability and reliability of the same system vary greatly due to the quality of the matching braking system. The system based on millimeter wave radar and camera information fusion is worse than that of pure vision technology due to the effect of fusion algorithm and other reasons. Furthermore, we point out some problems existing in the test and evaluation of commercial vehicle under a single test scenario and put forward some relevant suggestions. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Monolithic integration has been demonstrated to be an ideal solution to minimize the parasitics in GaN power IC. Nonetheless, the current commercially GaN process for power IC is far less mature and only n-type HEMTs are available. Therefore, it is difficult for high voltage level shifters to achieve high speed. This work implements a level shifter for GaN IC to achieve both small response time and high d VSdt noise immunity without complicated signal processing circuits, thus delay and conduction loss will be minimized. The proposed circuit was fabricated in a $1μm GaN-on-Silicon process and measured results were performed to verify the characteristics. © 2023 IEEE.

Traditional Chinese long text automatic classification methods have the problem of missing analysis information, which leads to a low recall rate. This paper designs an automatic Chinese long text classification method based on deep transfer learning algorithm. The literal similarity is obtained, and the morphemes are processed by weighting and quantization. On this basis, the noise data is eliminated, and the dimensionality of the structural features of the Chinese long text is reduced. A deep transfer learning algorithm is used to count the word segmentation information and minimize the loss function value of the category classifier. The relationship between document characteristics and document categories is explored, and an automatic classification mode is set. Experimental results: The recall rates of the Chinese long text automatic classification method in this paper and the other two automatic classification methods are 77.096%, 66.897%, 66.762%, indicating that the performance of the Chinese long text automatic classification method combined with the deep transfer learning algorithm is better. © 2021 IEEE.

This study presents novel magnetic core designs, magnetically anisotropic plain or tiled types, for planar spiral inductors that can effectively use magnetic anisotropy in the place of nano-granular [CoFeB-SiO2/SiO2] laminated magnetic cores. Inductance and resonant frequency for the proposed inductors showed significant enhancement through both finite element method calculation and experimentation. Additionally, the inductor was implemented onto a DC-DC converter successfully to demonstrate the step-down performance and showing corresponding waveforms. The efficiency of DC-DC converter with the inductor exhibited higher values under light load conditions. This comprehensive demonstration highlights the potential of our innovative design for advancing the field of integrated magnetics and developing more efficient power electronic devices. © 2025 IEEE.
