The Path Towards Smart Cities in China: From the Case of Shanghai Expo 2010
With the development of the digital technology, physical buildings are becoming more and more intelligent, high-efficiency and ecological; partial physical situational functions could be transferred to the virtual building world in a more efficient, intensive and convenient way. With these great achievement, we should believe that the digital technology will create more chances for the future of the smart buildings, and the smart city will be the most important foundation. To create the best human dwelling environment, we should construct smart buildings on the microscopic level and smart city on the macroscopic level. Smart city is not just about technology, but also the all-round innovation of the urban space, economic, society, system and management. The promotion for smart city will improve the quality of the urbanization, and the integrated development of the informatization, industrialization and urbanization, which will result in a wide influence on the city development and reform.
Being a developing country severely hit by information and technology revolution, China met a small climax of smart city construction after 2010 Expo. As the theme of 2010 Expo, the idea of 'better city better life' was implemented through the process of the planning, construction, development operation and utilization in the Expo Park of 5.28 km2 area, which made the best use of information and intelligent technology, as well as the idea of sustainable development. Intelligent and ecological buildings in Shanghai 2010 Expo have been the most important practice in China, which had effected profoundly on the construction of smart buildings and smart city.
At the beginning, this paper will introduce the background of of 'smart city', as well as it's meaning and feature. Then, through the case study of 2010 Expo, this paper will present a real scene of the development of smart cities in China. It reflected the path to smart cities in China, and the policies and achievements in large pilot cities during this process. It will also talk about the influence on urban planning and authorities. Obviously, when we talk about smart city, we should not only pay attention to its present, but also look forward to future, which is the last part in this paper
Improving Question Generation with Sentence-level Semantic Matching and Answer Position Inferring
Taking an answer and its context as input, sequence-to-sequence models have
made considerable progress on question generation. However, we observe that
these approaches often generate wrong question words or keywords and copy
answer-irrelevant words from the input. We believe that lacking global question
semantics and exploiting answer position-awareness not well are the key root
causes. In this paper, we propose a neural question generation model with two
concrete modules: sentence-level semantic matching and answer position
inferring. Further, we enhance the initial state of the decoder by leveraging
the answer-aware gated fusion mechanism. Experimental results demonstrate that
our model outperforms the state-of-the-art (SOTA) models on SQuAD and MARCO
datasets. Owing to its generality, our work also improves the existing models
significantly.Comment: Revised version of paper accepted to Thirty-fourth AAAI Conference on

A New Image Quality Database for Multiple Industrial Processes
Recent years have witnessed a broader range of applications of image
processing technologies in multiple industrial processes, such as smoke
detection, security monitoring, and workpiece inspection. Different kinds of
distortion types and levels must be introduced into an image during the
processes of acquisition, compression, transmission, storage, and display,
which might heavily degrade the image quality and thus strongly reduce the
final display effect and clarity. To verify the reliability of existing image
quality assessment methods, we establish a new industrial process image
database (IPID), which contains 3000 distorted images generated by applying
different levels of distortion types to each of the 50 source images. We
conduct the subjective test on the aforementioned 3000 images to collect their
subjective quality ratings in a well-suited laboratory environment. Finally, we
perform comparison experiments on IPID database to investigate the performance
of some objective image quality assessment algorithms. The experimental results
show that the state-of-the-art image quality assessment methods have difficulty
in predicting the quality of images that contain multiple distortion types
Reduced Expression of DNA Repair and Redox Signaling Protein APE1/Ref-1 Impairs Human Pancreatic Cancer Cell Survival, Proliferation, and Cell Cycle Progression
Pancreatic cancer is a deadly disease that is virtually never cured. Understanding the chemoresistance intrinsic to this cancer will aid in developing new regimens. High expression of APE1/Ref-1, a DNA repair and redox signaling protein, is associated with resistance, poor outcome, and angiogenesis; little is known in pancreatic cancer. Immunostaining of adenocarcinoma shows greater APE1/Ref-1 expression than in normal pancreas tissue. A decrease in APE1/Ref-1 protein levels results in pancreatic cancer cell growth inhibition, increased apoptosis, and altered cell cycle progression. Endogenous cell cycle inhibitors increase when APE1/ Ref-1 is reduced, demonstrating its importance to proliferation and growth of pancreatic cancer
FinLLMs: A Framework for Financial Reasoning Dataset Generation with Large Language Models
Large Language models (LLMs) usually rely on extensive training datasets. In
the financial domain, creating numerical reasoning datasets that include a mix
of tables and long text often involves substantial manual annotation expenses.
To address the limited data resources and reduce the annotation cost, we
introduce FinLLMs, a method for generating financial question-answering data
based on common financial formulas using Large Language Models. First, we
compile a list of common financial formulas and construct a graph based on the
variables these formulas employ. We then augment the formula set by combining
those that share identical variables as new elements. Specifically, we explore
formulas obtained by manual annotation and merge those formulas with shared
variables by traversing the constructed graph. Finally, utilizing GPT-3.5, we
generate financial question-answering data that encompasses both tabular
information and long textual content, building on the collected formula set.
Our experiments demonstrate that synthetic data generated by FinLLMs
effectively enhances the performance of several large-scale numerical reasoning
models in the financial domain, outperforming two established benchmark
financial question-answering datasets.Comment: Under submission of IEEE Transaction
A potential anti-tumor herbal medicine, Corilagin, inhibits ovarian cancer cell growth through blocking the TGF-β signaling pathways
BACKGROUND: Phyllanthus niruri L. is a well-known hepatoprotective and antiviral medicinal herb. Recently, we identified Corilagin as a major active component with anti-tumor activity in this herbal medicine. Corilagin is a member of the tannin family that has been discovered in many medicinal plants and has been used as an anti-inflammatory agent. However, there have been few reports of the anti-tumor effects of Corilagin, and its anti-tumor mechanism has not been investigated clearly. The aim of the present study is to investigate the anticancer properties of Corilagin in ovarian cancer cells. METHODS: The ovarian cancer cell lines SKOv3ip, Hey and HO-8910PM were treated with Corilagin and analyzed by Sulforhodamine B (SRB) cell proliferation assay, flow cytometry, and reverse phase protein array (RPPA). Corilagin was delivered intraperitoneally to mice bearing SKOv3ip xenografts. RESULTS: Corilagin inhibited the growth of the ovarian cancer cell lines SKOv3ip and Hey, with IC50 values of less than 30 μM, while displaying low toxicity against normal ovarian surface epithelium cells, with IC50 values of approximately 160 μM. Corilagin induced cell cycle arrest at the G2/M stage and enhanced apoptosis in ovarian cancer cells. Immunoblotting assays demonstrated that Cyclin B1, Myt1, Phospho-cdc2 and Phospho-Weel were down-regulated after Corilagin treatment. Xenograft tumor growth was significantly lower in the Corilagin-treated group compared with the untreated control group (P <0.05). More interestingly, Corilagin inhibited TGF-β secretion into the culture supernatant of all tested ovarian cancer cell lines and blocked the TGF-β-induced stabilization of Snail. In contrast, a reduction of TGF-β secretion was not observed in cancer cells treated with the cytotoxic drug Paclitaxel, suggesting that Corilagin specifically targets TGF-β secretion. Corilagin blocked the activation of both the canonical Smad and non-canonical ERK/AKT pathways. CONCLUSIONS: Corilagin extracted from Phyllanthus niruri L. acts as a natural, effective therapeutic agent against the growth of ovarian cancer cells via targeted action against the TGF-β/AKT/ERK/Smad signaling pathways
Open Compound Domain Adaptation with Object Style Compensation for Semantic Segmentation
Many methods of semantic image segmentation have borrowed the success of open
compound domain adaptation. They minimize the style gap between the images of
source and target domains, more easily predicting the accurate pseudo
annotations for target domain's images that train segmentation network. The
existing methods globally adapt the scene style of the images, whereas the
object styles of different categories or instances are adapted improperly. This
paper proposes the Object Style Compensation, where we construct the
Object-Level Discrepancy Memory with multiple sets of discrepancy features. The
discrepancy features in a set capture the style changes of the same category's
object instances adapted from target to source domains. We learn the
discrepancy features from the images of source and target domains, storing the
discrepancy features in memory. With this memory, we select appropriate
discrepancy features for compensating the style information of the object
instances of various categories, adapting the object styles to a unified style
of source domain. Our method enables a more accurate computation of the pseudo
annotations for target domain's images, thus yielding state-of-the-art results
on different datasets.Comment: Accepted by NeurlPS202
