Research on World Consciousness in Guo Moruo’s Poetry

This article starts from the world trend of thought absorbed by Guo Moruo, sorts out Guo Moruo’s world consciousness and the dynamic process of his acceptance of world trends, and explores the reasons why these advanced trends of thought were applied by Guo Moruo in combination with Guo Moruo’s life experience and spiritual life. Finally, the authors return to Guo Moruo’s poetry works and analyze how these ideological currents have brought about some important changes in his poetry creation, leading to some of his poetry works presenting new characteristics and becoming a revolutionary milestone in the history of literature

HAL: Improved Text-Image Matching by Mitigating Visual Semantic Hubs

The hubness problem widely exists in high-dimensional embedding space and is a fundamental source of error for cross-modal matching tasks. In this work, we study the emergence of hubs in Visual Semantic Embeddings (VSE) with application to text-image matching. We analyze the pros and cons of two widely adopted optimization objectives for training VSE and propose a novel hubness-aware loss function (HAL) that addresses previous methods' defects. Unlike (Faghri et al.2018) which simply takes the hardest sample within a mini-batch, HAL takes all samples into account, using both local and global statistics to scale up the weights of "hubs". We experiment our method with various configurations of model architectures and datasets. The method exhibits exceptionally good robustness and brings consistent improvement on the task of text-image matching across all settings. Specifically, under the same model architectures as (Faghri et al. 2018) and (Lee at al. 2018), by switching only the learning objective, we report a maximum R@1improvement of 7.4% on MS-COCO and 8.3% on Flickr30k.Comment: AAAI-20 (to appear

Environment Geophysics on Environmental protection in China

The environmental problem conexists with the birth and development of human being. When people entered on the Industrial Revolution, especially the twentieth century, with the rapid improvement of the productivity level, the natural resources has been exploited and used at the unprecedented level. When people are creating the material wealth, they are also producing more and more pollution. The environmental problem has been more and more serious. This problem has already done harm to the human existence directly. In recent 20 years, the environmental problem has been one of the most important problems that people are concerned with. In China, there are also many environmental problems such as air pollution, water pollution, refuse treatment, desertification, sand calamity, soil erosion, drought, flood, biodiversity damage,and so on. Some of these problems have already affected the development of national economy and the living of people. So using the modern technology, uniting different subjects, studying these problems roundly and systematacially, and harnessing the pollution are important to the sustainable development of the society and economy. Key words: Geophysics; Environmental protection; pollutio

catena-Poly[[bis­(1-allyl­imidazole)zinc(II)]-μ-phthalato-κ2 O 1:O 2]

The structure of the title compound, [Zn(C8H4O4)(C6H8N2)2]n, exhibits polymeric zigzag chains extended along the c axis. The ZnII ion is coordinated by two N [Zn—N = 2.008 (6) and 2.012 (6) Å] and two O [Zn—O = 1.959 (5) and 1.985 (5) Å] atoms in a distorted tetra­hedral geometry. Weak C—H⋯O inter­actions contribute to the crystal packing stability

Aperture Diffraction for Compact Snapshot Spectral Imaging

We demonstrate a compact, cost-effective snapshot spectral imaging system named Aperture Diffraction Imaging Spectrometer (ADIS), which consists only of an imaging lens with an ultra-thin orthogonal aperture mask and a mosaic filter sensor, requiring no additional physical footprint compared to common RGB cameras. Then we introduce a new optical design that each point in the object space is multiplexed to discrete encoding locations on the mosaic filter sensor by diffraction-based spatial-spectral projection engineering generated from the orthogonal mask. The orthogonal projection is uniformly accepted to obtain a weakly calibration-dependent data form to enhance modulation robustness. Meanwhile, the Cascade Shift-Shuffle Spectral Transformer (CSST) with strong perception of the diffraction degeneration is designed to solve a sparsity-constrained inverse problem, realizing the volume reconstruction from 2D measurements with Large amount of aliasing. Our system is evaluated by elaborating the imaging optical theory and reconstruction algorithm with demonstrating the experimental imaging under a single exposure. Ultimately, we achieve the sub-super-pixel spatial resolution and high spectral resolution imaging.
