Efficient Fully Convolution Neural Network for Generating Pixel Wise Robotic Grasps With High Resolution Images

This paper presents an efficient neural network model to generate robotic grasps with high resolution images. The proposed model uses fully convolution neural network to generate robotic grasps for each pixel using 400 $\times$ 400 high resolution RGB-D images. It first down-sample the images to get features and then up-sample those features to the original size of the input as well as combines local and global features from different feature maps. Compared to other regression or classification methods for detecting robotic grasps, our method looks more like the segmentation methods which solves the problem through pixel-wise ways. We use Cornell Grasp Dataset to train and evaluate the model and get high accuracy about 94.42% for image-wise and 91.02% for object-wise and fast prediction time about 8ms. We also demonstrate that without training on the multiple objects dataset, our model can directly output robotic grasps candidates for different objects because of the pixel wise implementation.Comment: Submitted to ROBIO 201

Boundedness of the product of some operators from the natural Bloch space into weighted-type space

Let $\mathbb{B}_X$ be the unit ball of a complex Banach space $X$, which may be infinite dimensional. The authors characterize the boundedness of the product of the radial derivative operator and the weighted composition operator from the natural Bloch space (or the little Bloch-type space) into the weighted-type space (or the little weighted-type space) on $\mathbb{B}_X$

Spatial Organization in Proteinaceous Membrane‐Stabilized Coacervate Protocells

As a model protocell, the membrane-free coacervate microdroplet is widely utilized in functional studies to provide insights into the physicochemical properties of the cell and to engineer cytomimetic soft technologies; however, the lack of a discrete membrane contributes to its instability and limits further application. Herein, a strategy is developed to fabricate a hybrid protocell based on the self-assembly of a proteinaceous membrane at the surface of coacervate microdroplets driven by a combination of electrostatic adhesion and steric/hydrophilic surface buoyancy. The semipermeable proteinaceous membrane can enhance coacervate stability obviously without compromising sequestration behavior. Significantly, such hybrid protocells demonstrate spatial organization whereby various functional enzymes can be located in discrete regions, which facilitates an on/off modulation for a cascade enzymatic reaction along with enhanced chemical communication between subpopulations

Negative transfer and english writing proficiency among junior middle school students in China

English and Chinese exhibit notable differences across various linguistic aspects. Hypotaxis is a significant feature emphasized in English, whereas parataxis holds prominence in Chinese. Proficiency in writing is a crucial skill to acquire in English language learning, involving the mastery of vocabulary, syntax, and grammar. Chinese students often encounter challenges in comprehending these concepts, resulting in inevitable errors in their written compositions. Such errors can be attributed to the negative transfer effect stemming from their mother tongue (i.e. Chinese). Negative transfer from Chinese may impede or disrupt the acquisition of a second language. Furthermore, the stark sociocultural disparities between Chinese and Western cultures lead to the inadvertent application of Chinese language rules in English expression, consequently compromising accurate usage. This paper utilizes language negative transfer theory, alongside comparative and error analysis theories, to analyze how mother tongue negative transfer affects the English writing proficiency of junior middle school students. Specifically, the study examines the influence of negative transfer on grammar, vocabulary, and discourse. Data for this investigation is collected through the analysis of composition materials. Additionally, the paper concludes by offering recommendations to mitigate the adverse effects of mother tongue negative transfer on English writing proficiency, with the goal of improving English language instruction for Chinese students

Exploring the connection between attitudes towards new chinglish and social media among Chinese college students

New Chinglish has emerged as an undeniable and popular trend on Chinese social media platforms, particularly among Chinese college students. These college students are not only the main force of English users and learners in China but also the major netizens on Chinese social media platforms. However, within a cultural context where ‘standards and adherence to norms have traditionally been of paramount importance to the Chinese’ (Kirkpatrick, 2017: 278), the conflicting attitudes and use towards either upholding traditional viewpoints or adopting opposing stances regarding the New Chinglish warrant intriguing and meaningful exploration. Thus, this study aims to explore the connection between their attitudes towards New Chinglish and its usage behaviors on social media among Chinese college students. It seeks to unveil the reasons underlying their attitudes towards the use of New Chinglish. The indepth exploration reveals a contradictory and uncertain evaluation of their usage of New Chinglish on social media, despite its high level of understandability and acceptability among them. Personal acceptability and preference do not solely determine their attitudes towards their use of New Chinglish on social media; instead, various social factors, such as language inequality, influence their language use behavior and attitudes, leading to a compromise between individual preferences and social influences. Specifically, this study offers insight into the genuine reactions and usage tendencies of English in real-life situations, indicating the future trends in English language development in China

Chinglish: Unraveling the Cultural and Cognitive Pattern Differences in Cross-Linguistic Communication

English, as a foreign language in China, is often influenced by the first language (L1), which is Chinese, giving rise to the phenomenon of Chinglish. Chinglish, a distinct English variety, significantly differs from standard English in various aspects. The prominent reason for these differences lies in the variance of culture and thinking patterns. Unfortunately, Chinglish impedes effective cross-cultural communication and hinders the advancement of English learners’ proficiency. This study aims to elucidate the current state and specific manifestations of Chinglish concerning vocabulary and syntax from the perspective of cultural and cognitive disparities. The research employs questionnaire surveys and material analysis methods to gather data. Preliminary analysis reveals the widespread prevalence of Chinglish during the English learning process, with the primary vocabulary errors being redundancy, improper word usage, and incorrect collocation. In terms of syntax, word order, tense, and voice are particularly discussed as problematic areas. This paper concludes with suggestions for avoiding Chinglish, aiming to enhance cross-cultural communication and elevate English proficiency levels among Chinese learners
