Bin Jia, Jianping Jing, Xuedong Qiao, Chunming Zhang
Journal of Applied Mathematics and Physics (JAMP) , 2013, DOI: 10.4236/jamp.2013.16015
Abstract: In this paper numerical simulation of PRHR HX and IRWST is demonstrated using FLUENT, and different numbers of C-type heat transfer tubes and coolant inlet temperature’s effects for the residual heat removal capacity of PRHR HX, IRWST thermal stratification and natural circulation have been researched. It’s found that at a constant flow area when heat transfer tubes’ number increased outlet temperature of PRHR HX is lower, the whole water temperature of IRWST is higher, thermal stratification and natural circulation are more oblivious. At a constant mass flow when inlet temperature of PRHR HX increased, inlet flow velocity increases and outlet temperature is higher. But on the other hand the cooling rate increases at the same time, the average temperature of IRWST is higher, the range of thermal stratification expands and the velocity of natural circulation increases.

Guodong Sun,Guofu Qiao,Bin Xu
International Journal of Distributed Sensor Networks , 2012, DOI: 10.1155/2012/519792
Abstract: With the increasing demands on the remote healthcare and the rich human-machine interacting, body area sensor network (BASN) has been attracting more and more attention. In practice, understanding the link performance and its dynamics in the emerging BASN applications is very important to design reliable, real-time, and energy-efficient protocols. In this paper we study the link characteristics of body area sensor network (BASN) through extensive experiments with very realistic configurations. We evaluate the packet reception ratio, RSSI, LQI, and movement intensity of body under indoor and outdoor environments, all of which can provide direct insights to practical account. 1. Introduction Recently, the emerging body area sensor network (BASN) [1–3] has established itself into an important branch of pervasive computing and personal communications, and more and more BASN-based applications are employed in remote healthcare monitoring as well as wearable medical systems [4–10] and human-centric context recognition [11–15]. In a typical BASN, multiple sensors are attached on or implanted in the human body, and they sample physiological data, such as acceleration, heart rate, SpO2, and breath apnea interval, and transmit these data through wireless channel to a gateway (e.g., mobile phone), which is often carried by users. The gateway performs further computation and communication tasks—diverse interactions with users or services. By far, the operation frequency likely used in BASN ranges from the low-frequency band such as 10?MHz, the industrial-scientific-medical (ISM) band from 2.4 to 2.8?GHz, and to the ultra-wideband (UWB) standard. Bluetooth and IEEE 802.15.4 are two commonly-used 2.4?GHz communication standard. However, Bluetooth has a complicated protocol stack and runs with more energy than 802.15.4, so most literatures and applications use 802.15.4 as their communication protocols, and, in practice, the number of applications using IEEE 802.15.4-based 2.4?GHz devices has been increasing, which is the main motivation of carrying out our work at 2.4?GHz. To design reliable, robust, energy-efficient communication protocol, BASN designers must know how links vary with time and what factors affect the link dynamics. Understanding and profiling the BASN links are very important and very challenging in implementing BASN applications of high efficiency. We argue that the existing investigations of BASN link dynamics, either under a few well-controlled movements or a completely real-world movements, cannot provision a continuous, accurate snapshot for the
In-plane Chiral Tunneling and Out-of-plane Valley-polarized Quantum Tunneling in Twisted Graphene Trilayer
Jia-Bin Qiao,Lin He
Physics , 2014, DOI: 10.1103/PhysRevB.90.075410
Abstract: Here we show that twisted graphene trilayer made by misoriented stacking a graphene monolayer on top of a Bernal graphene bilayer can exhibit rich and tailored electronic properties. For the case that the graphene monolayer and bilayer are strongly coupled, both the massless Dirac fermions and massive chiral fermions coexist in the twisted trilayer, leading to unique in-plane chiral tunneling. For a weak coupling between the two graphene systems, the distinct chiralities and pseudospin textures of quasiparticles in monolayer and bilayer enable vertical valley-polarized quantum tunneling between them. Intriguingly, the polarity of the valley polarization can be inverted by controlling the rotational angles between the two systems. Our results indicate that layered van der Waals structures assembled from individual atomic planes can create materials that harbor unusual properties and new functionalities depending on how the crystalline layers are stacked.
Analysis and Prediction of Collateral Channels from Left Superior Vena Cava after Bilateral Bidirectional Cavopulmonary Anastomosis  [PDF]
Biao Si, Bin Qiao, Tongjian Wang, Yansong Ning, Meng Zhu, Na Li
World Journal of Cardiovascular Diseases (WJCD) , 2018, DOI: 10.4236/wjcd.2018.84023
Abstract: Objectives: To analyze and predict collateral channels in bilateral bidirectional cavopulmonary anastomosisfocused on that from left superior vena cava. Methods: 41 consecutive patients who all underwent bilateral bidirectional cavopulmonary anastomosis were enrolled the study. The number, shape, size, origin and entry, and course of collateral vessels from left superior vena cava were referred for evaluation based on 41 cardiac angiographies. The influential factors on the formation of collateral vessels were identified by binary logistic regression analysis. Results: The number of the left superior vena cava with collateral vessels was larger than right one, 22 versus 8 (X2 = 10.303, P = 0.001). The medium-distal parts of left systemic vena were prone to development of collateral channel. The logic function with respect to the probability of left systemic venous collateral channel could be expressed as the linear expression of left systemic venous pressure x: 0.418
Amelioration of Lupus Nephritis by Serum Amyloid P Component Gene Therapy with Distinct Mechanisms Varied from Different Stage of the Disease
Weijuan Zhang,Jin Wu,Bin Qiao,Wei Xu,Sidong Xiong
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0022659
Abstract: Our previous study revealed that administration of syngeneic female BALB/c mice with excessive self activated lymphocyte-derived DNA (ALD-DNA) could induce systemic lupus erythematosus (SLE) disease, indicating that overload of self-DNA might exceed normal clearance ability and comprise the major source of autoantigens in lupus mice. Serum amyloid P component (SAP), an acute-phase serum protein with binding reactivity to DNA in mice, was proved to promote the clearance of free DNA and prevent mice against self-antigen induced autoimmune response. It is reasonable to hypothesize that SAP treatment might contribute to alleviation of SLE disease, whereas its role in ALD-DNA-induced lupus nephritis is not fully understood.
A Transformtion in Literati Painting as Reflected from the Northern Song to the Southern Song Dynasties

DENG Qiao-bin,

浙江大学学报(人文社会科学版) , 2005,
Abstract: 北宋诗文革新运动影响了绘画,"破体"为文而至绘事,颇多诗画相通之论.以苏轼为代表的文人画理论主要体现在三个方面:(1)提出了系统的画家修养论;(2)倡导绘画的传神论;(3)确立了"书画当观韵"的标准.在创作上大致可分三类,其中,苏轼、文同、米芾等被视作典型的文人画.南宋文人画的逐渐退潮,除了院画兴盛的外部因素外,更出于自身的原因.其变化与转型体现在五个方面:(1)文人画几可看作是画院以外绘画的代称;(2)有借鉴院画之长并与院画结合之势;(3)创作主力转移到水墨竹石花卉;(4)开绘画与诗、书、印结合之先河;(5)僧道作品形成了狂逸的创作风气.

Zhang Bin,Wen Qiao,Chu Xiao-Liang,

中国物理 B , 2003,
Abstract: Theory of the coherent-mode decomposition of laser beams is proposed. The new model for the flat-topped beams proposed by Li recently is taken as an example. The analytical expressions for the M^2-factor and mode coherence coefficients of flat-topped beams have been derived in the rectangular coordinate system, by means of which the mode correlation, mode structure, and coherent-mode decomposition of flat-topped beams can be analysed.
Extending XML Schema with Object-oriented Features
Guoren Wang,Donghong Han,Baiyou Qiao,Bin Wang
Information Technology Journal , 2005,
Abstract: In this study, we extend XML Schema with nonmonotonic inheritance due to its powerful modeling ability to support multiple inheritance, overriding of elements or attributes inherited from super-elements, blocking of the inheritance of elements or attributes from super-elements and conflict handling. Another key feature of object-oriented data models is polymorphism. We introduce it into XML Schema to support polymorphic elements and polymorphic references. Moreover, we define a formalization to represent these features and present some validation rules to validate whether an XML instance document conforms to an Extended XML Schema based on the formalization. Finally, we extend XQuery to support the polymorphic feature.
Design and Implementation of a Semantic Document Management System
Guoren Wang,Bin Wang,Donghong Han,Baiyou Qiao
Information Technology Journal , 2005,
Abstract: Easily accessible information on the World Wide Web (WWW) and affordable large capacity secondary storage make it easy to build up very large document collections even in personal computers. However, the method of organizing files in computers has not been changed too much for decades. Searching for a particular document or file from a gegabytes collection based on traditional tree structured file directories becomes never an easy task. This study presents a system where documents are no longer identified by their file names. Instead, a document is represented by its semantics in terms of descriptor and contents vector. The descriptor of a document consists of a set of attributes, such as date of creation, its type, its size, annotations, etc. The content vector of a document consists of a set of terms extracted from the document. Such semantic information provides the user with associative searching capability, that is, documents can be obtained by giving required properties. The representation of document semantics and document organization and key word-based indexing techniques are discussed. Furthermore, for the largely used XML data in Web representing and exchanging, some structure-based querying techniques are proposed in this study, i.e. structural indexes and path expression optimization principles. A prototype visual based explorer that makes use of semantics of documents is also described.
