A Study of Intonation of English Sentences of College Students Whose Mother Tongue is Beijing Dialect Taking Interrogative Sentences as Examples

During the last decade, college students paid more attention to their intonation of oral English when they need to communicate with foreigners. However, very little research has been focused on the situation of learners with Beijing dialect. The aim of this study was to investigate the negative transfer of Beijing dialect on interrogative sentences in three different contexts while indicating the possible reasons and solutions to the negative transfer. The research objects of this paper were all students with Beijing accent at Capital Normal University. Comparative analysis of data, questionnaire and interview methods were used in the research. Results of the assessment showed that subjects generally consciously emphasized the pitch of the sentence focus, but their intonation fluctuated little on the whole. At the same time, they are not good at using falling and rising intonation to verify the information. Furthermore, they were more inclined to use a rising tone for different types of questions. This suggested that both learners and teachers should pay more attention to training time, language environment and psychological factors during training.

Pulsed infrared thermographic study of a Chinese Bronze Lei

In this paper, pulsed infrared thermography is applied to the study of a mold casting Chinese bronze lei 罍 dated to the late Shang dynasty (c.a.1250–1050 BC), currently housed in the Capital Normal University Museum. Many spacers and a defective area of this ancient bronze are partly covered with repair material. By analyzing thermographic images using a one-layer thermal diffusion model, it is found that the spacers were specifically made for this bronze. The thickness of the repairing material in the defective area is measured using thermal quadrupole modelling in multi-layer materials. This is the first application of this method to the field of cultural heritage conservation. These results provide a deeper understanding of the manufacturing process of ancient Chinese bronzes from the viewpoint of archaeological research. They also help assess the repair status from the conservation viewpoint.

On the traditions and trends of ethnosemiotics in China: an interview with Prof. Hongwei Jia

Abstract Charles Sanders Peirce highlights that “the entire world is perfused with signs.” That is, nothing can exist without signs. Ethnology is no exception in this light. Up to now, ethnology has not been exhaustively examined in terms of semiotics, nor has it combined with semiotics effectively and efficiently in China, with its multiple ethnic groups and multi-millenary tradition of knowledge. To promote the further development of ethnology in China in terms of semiotics, as well as the development of Chinese ethnosemiotics at the embryonic stage, I conducted an interview with Prof. Hongwei Jia, a semiotician based at Capital Normal University in Beijing and meanwhile serving as the founding Director of the Center for Semiotics and Cultural Studies at Shinawatra University in Bangkok. This interview focuses on the relationship between ethnology and semiotics, as well as the origin, application, and development of ethnosemiotics in China, in order to inspire further related research and promote the future development of this area.

Short-Term Bathwater Demand Forecasting for Shared Shower Rooms in Smart Campuses Using Machine Learning Methods

Water scarcity is a growing threat to humankind. At university campuses, there is a need for shared shower room managers to forecast the demand for bath water accurately. Accurate bath water demand forecasts can decrease the costs of water heating and pumping, reduce overall energy consumption, and improve student satisfaction (due to stability of bath water supply and bathwater temperature). We present a case study conducted at Capital Normal University (Beijing, China), which provides shared shower rooms separately for female and male students. Bath water consumption data are collected in real-time through shower tap controllers to forecast short-term bath water consumption in the shower buildings. We forecasted and compared daily and hourly bath water demand using the autoregressive integrated moving average, random forests, long short-term memory, and neural basis expansion analysis time series-forecasting models, and assessed the models’ performance using the mean absolute error, mean absolute percentage error, root-mean-square error, and coefficient of determination equations. Subsequently, covariates such as weather information, student behavior, and calendars were used to improve the models’ performance. These models achieved highly accurate forecasting for all the shower room areas. The results imply that machine learning methods outperform statistical methods (particularly for larger datasets) and can be employed to make accurate bath water demand forecasts.

Deep Learning Quantum States for Hamiltonian EstimationSupported by the National Natural Science Foundation of China (Grant Nos. 12004266, 11834014 and 11975050), the Beijing Natural Science Foundation (Grant Nos. 1192005 and Z180013), the Foundation of Beijing Education Committees (Grant No. KM202010028013), and the Academy for Multidisciplinary Studies, Capital Normal University.

Human experts cannot efficiently access physical information of a quantum many-body states by simply “reading” its coefficients, but have to reply on the previous knowledge such as order parameters and quantum measurements. We demonstrate that convolutional neural network (CNN) can learn from coefficients of many-body states or reduced density matrices to estimate the physical parameters of the interacting Hamiltonians, such as coupling strengths and magnetic fields, provided the states as the ground states. We propose QubismNet that consists of two main parts: the Qubism map that visualizes the ground states (or the purified reduced density matrices) as images, and a CNN that maps the images to the target physical parameters. By assuming certain constraints on the training set for the sake of balance, QubismNet exhibits impressive powers of learning and generalization on several quantum spin models. While the training samples are restricted to the states from certain ranges of the parameters, QubismNet can accurately estimate the parameters of the states beyond such training regions. For instance, our results show that QubismNet can estimate the magnetic fields near the critical point by learning from the states away from the critical vicinity. Our work provides a data-driven way to infer the Hamiltonians that give the designed ground states, and therefore would benefit the existing and future generations of quantum technologies such as Hamiltonian-based quantum simulations and state tomography.

New eodermapteran earwigs (Dermaptera) from the Middle Jurassic Jiulongshan Formation of China

A new genus of eodermapteran earwigs, Aglyptoderma gen. nov., is described from the Middle Jurassic Jiulongshan Formation of Inner Mongolia, China. It comprises two new species—Aglyptoderma elongatum gen. et sp. nov. and Aglyptoderma cylindratum gen. et sp. nov. The genus belongs to the family Semenoviolidae, hitherto known only from the Late Jurassic of Kazakhstan. However, owing to significant differences in the form of the head, pronotum, tegmina and tarsomeres, the new genus is classified within a separate subfamily, Aglyptodermatinae subfam. nov. The features of the new genus are discussed in the context of existing hypotheses regarding post-Jurassic character-state transitions in the postabdomen of female Dermaptera. In particular, reduction of the cerci and internalization of the ovipositor across Archidermaptera, Eodermaptera, and Neodermaptera may relate to the variety of maternal care behaviours seen among earwigs.

Optimized monogamy and polygamy inequalities for multipartite qubit entanglement* *Project supported by the National Natural Science Foundation of China (Grant Nos. 12075159 and 11847209), Beijing Natural Science Foundation (Grant No. Z190005), Academy for Multidisciplinary Studies, Capital Normal University, the Academician Innovation Platform of Hainan Province, Shenzhen Institute for Quantum Science and Engineering, Southern University of Science and Technology (Grant No.

We investigate the monogamy and polygamy inequalities of arbitrary multipartite quantum states, and provide new classes of monogamy and polygamy inequalities of multiqubit entanglement in terms o f concurrence, entanglement of formation, negativity, and Tsallis-q entanglement, respectively. We show that these new monogamy and polygamy inequality relations are tighter than the existing ones with detailed examples.

Online Shopping Behaviour among International Students from Belt & Road Countries in China

The rapid transformation of e-platforms and the growth of e-commerce in China provide consumers with the most advanced channels and creative options for buying and selling through online podium. Online shopping is categorically going to be the world's future shopping mode. Besides, The Belt and Road Initiative (BRI) of China aims to place the world on a new trajectory of higher growth and human development through the connectivity of infrastructure, increased trade, and investment. Cross-border online shopping has become one of the forthcoming prime business models through the implication of the Belt & Road Initiative. By analyzing the representative group of consumers from Belt & Road countries, this study is to explore possible guiding constraints about online shopping decisions that may assist to understand behavioral traits to cross-border online shopping. In the expansion of online shopping, consumers, particularly young people, and students play the most important role. It is, therefore, imperative for companies to investigate and consider the factors that affect the decision of students and young people to get online shopping. This paper has attempted to explore various factors that will affect the online shopping decision of consumers particularly from Belt & Road countries. During this analysis, a qualitative study approach was adopted and a sample of 105 higher education students from the Belt & Road Initiative (BRI) countries studying at Capital Normal University was drawn up. The study will ascertain the ‘Online Shopping Behaviors’ of typical consumers from BRI (Belt & Road) countries to explore a wider direction for cross-border online shopping decisions. It is discovered that online shopping makes life easier, and it is not so far that online shopping can infinitely overtake conventional physical shopping in the whole world.

Measurement of Tunnel Clearance Convergence Using Mobile Laser Detection Technology

Railway and subway tunnels have lengthy runs, long train operation times, high detection pressures, and critical structural safety concerns that affect tunnel service life, train safety, and passenger comfort. The current method of measuring the clearance convergence requires considerable manpower and equipment to identify defects, cannot measure the entire tunnel section, has poor operation efficiency, and provides noncomprehensive results. To address these shortcomings, three-dimensional laser scanning technology has recently been applied to tunnel structure inspection. This study therefore proposes methods for calculating the clearance convergence of a tunnel section, including the calculation of the shield tunnel convergence diameter, shield tunnel and mine tunneling method tunnel chord lengths, track gauge, guide height and offset of overhead lines, and vault clearance height. The tunnel point cloud data were acquired by the Capital Normal University (Beijing) mobile laser tunnel inspection vehicle and were processed using the algorithms developed in this study. The data indicate that the proposed method provides a repeatability and absolute accuracy within ±3 mm. The proposed method improves the efficiency of tunnel clearance convergence measurement by measuring the full section of a tunnel, providing technical support for the safe operation of subway and railway tunnels.

The Age Absent of Classics and the Writer’s Anxiety: An Interview with Yan Lianke

This interview was conducted on a summer day at the International Culture Center of Capital Normal University in Beijing: August 12, 2019. Suffering from a relapse of his backache, Yan Lianke had to talk and answer questions by reclining on the couch for nearly three hours. Despite of it, he was patient and impressively open to questions that may not have quick or easy answers. The interview covers a wide range of topics, primarily focusing on three aspects: 1) the multiple dimensions of Yan’s anxiety stemming from living in today’s social reality, literary creation itself, and the incapability of grasping the future; 2) Yan’s understanding of classics against the backdrop of contemporary Chinese literary reality; 3) the paradox of Yan’s emotional attachment to the “native soil” (xiangtu) both in life and in literature, and his perception of a writer’s social responsibility as not running away from the life with which one is most familiar.

The ‘Megasecoptera–Diaphanopterodea’ twilight zone epitomized by a new insect from Xiaheyan (Early Pennsylvanian; China)

A new species of ‘Megasecoptera-like’ insect, Sinodiapha ramosa gen. and sp. nov., is described based on two specimens from the Xiaheyan locality (early Pennsylvanian) of China, one of which displays a wing pair in the neopterous resting position. This unusual combination of venational features and neoptery indicates that the species belongs to the Diaphanopterodea, and that this order derived from the Megasecoptera. We establish the family Sinodiaphidae fam. nov. for the new genus, and the taxon Megasecopteromorpha for the two orders, the latter being most likely paraphyletic. The Diaphanopterodea are highly derived insects and therefore are of no particular relevance to elucidate the ancestral conditions of Pterygota.Nan Yang [yangnan0504@qq.com], Key Laboratory of Insect Evolution and Environmental Changes, Capital Normal University, Beijing 100048, PR China; Dong Ren [rendong@mail.cnu.edu.cn], College of Life Sciences, Capital Normal University, 105 Xisanhuanbeilu, Haidian District, Beijing 100048, PR China, and Academy for Multidisciplinary Studies, Capital Normal University, 105 Xisanhuanbeilu, Haidian District, Beijing 100048, PR China; Olivier Béthoux [obethoux@mnhn.fr], CR2P (Centre de Recherche en Paléontologie — Paris), MNHN – CNRS – Sorbonne Université, 57 rue Cuvier, CP38, F-75005, Paris, France.

Cross-Section Deformation Analysis and Visualization of Shield Tunnel Based on Mobile Tunnel Monitoring System.

With the ongoing developments in laser scanning technology, applications for describing tunnel deformation using rich point cloud data have become a significant topic of investigation. This study describes the independently developed a mobile tunnel monitoring system called the second version of Tunnel Scan developed by Capital Normal University (CNU-TS-2) for data acquisition, which has an electric system to control its forward speed and is compatible with various laser scanners such as the Faro and Leica models. A comparison with corresponding data acquired by total station data demonstrates that the data collected by CNU-TS-2 is accurate. Following data acquisition, the overall and local deformation of the tunnel is determined by denoising and 360° deformation analysis of the point cloud data. To enhance the expression of the analysis results, this study proposes an expansion of the tunnel point cloud data into a two-dimensional image via cylindrical projection, followed by an expression of the tunnel deformation through color difference to visualize the deformation. Compared with the three-dimensional modeling method of visualization, this method is easier to implement and facilitates storage. In addition, it is conducive to the performance of comprehensive analysis of problems such as water leakage in the tunnel, thereby achieving the effect of multiple uses for a single image.

A revision of Haidomyrmex cerberus Dlussky (Hymenoptera: Formicidae: Sphecomyrminae) from mid-Cretaceous Burmese amber

The type species of the genus Haidomyrmex Dlussky, 1996 is revised. Haidomyrmex cerberus was originally described based on a partial worker specimen only, which was later re-figured with some erroneous characters. Two worker specimens assignable to this species were recently discovered in the collection of Burmese amber from the Capital Normal University of Beijing. A revised description and comparison with the two other known species of Haidomyrmex are provided, and the diagnoses of the genus and species are emended.

New cockroaches (Insecta, Blattaria, Fuziidae) from the Middle Jurassic Jiulongshan Formation in northeastern China

LIANG, J., SHIH, C., WANG, L., & REN, D., 26 March 2019. New cockroaches (Insecta, Blattaria, Fuziidae) from the Middle Jurassic Jiulongshan Formation in northeastern China. Alcheringa 43, 441–448. ISSN 0311-5518.Fuziidae is a significant cockroach family reported only from the Middle Jurassic Jiulongshan Formation of northeastern China. Male Fuziidae with forceps-like cerci are unique in the 320 Ma history of cockroaches. Longifuzia pectinata gen. et sp. nov. is described from the Jiulongshan Formation based on four male specimens. It can be distinguished from other fuziids by its larger body size, extremely long telescopic abdomen, numerous forewing veins, characteristic coloration on the forewing and unique male genitalia. Three of four type specimens have asymmetric venation in the wings. The narrow and elongate body shape is suggestive of alternative, non-standard diets because a wide (fat) body is necessary for nitrogen fixation in cockroaches. Nevertheless, well-developed male tergal glands provide evidence of nuptial female feeding on nitrogen provisions. This new taxon expands the known diversity and highlights the morphological disparity of this family at the Daohugou locality in northeastern China.Junhui Liang* [liangjh0602@126.com], Tianjin Natural History Museum, 31 Youyi Road, Hexi District, Tianjin, 300201, PR China; Chungkun Shih† [chungkun.shih@gmail.com], College of Life Sciences, Capital Normal University, 105 Xisanhuanbeilu, Haidian District, Beijing, 100048, PR China; Lixia Wang [wlxwlx@163.com], The Geological Museum of China, Xisi, Xicheng District, Beijing 100034, PR China; Dong Ren [rendong@mail.cnu.edu.cn], College of Life Sciences, Capital Normal University, 105 Xisanhuanbeilu, Haidian District, Beijing, 100048, PR China. *Also affiliated with: College of Life Sciences, Capital Normal University, 105 Xisanhuanbeilu, Haidian District, Beijing, 100048, PR China. †Also affiliated with: Department of Paleobiology, National Museum of Natural History, Smithsonian Institution, Washington, DC 20013, USA.
