A novel technique of three-dimensional reconstruction segmentation and analysis for sliced images of biological tissues

INTRODUCTION The past decades witnessed unprecedented ad-vances in the imaging science fields(Yelbuz et al.,2002;Campagnola et al.,2002;Sharpe et al.,2002).The technique of3D image reconstruction andanalysis plays a significant role in the basic researchof life science,which developed from2D imageprocessing but provides more information than2Dimage,and has rapidly expanded to molecular andcellular field(Guo et al.,1995;Trehan et al.,2003).Despite the rapid development of the new field,…     

Cerebrospinal fluid and plasma propofol concentration during total intravenous anaesthesia of patients undergoing elective intracranial tumor removal

INTRODUCTION The specific morphologic properties of choroidal epithelium and the existence of a cerebrospinal fluid(CSF)pathway for drug distribution to the central nervous system(CNS)suggest that the choroid plexus-CSF route may be more significant than pre-viously thought for drug delivery to the brain(Ghersi-Egea and Strazielle,2001).There is limitedl d l d-n d information about the CSF pharmacokinetics of propofol in humans(Engdahl et al.,1998;Dawid-owicz et al.,2001a).Propofol…     

A Multicontextual Model for Broadening Participation in STEM Related Disciplines

This paper argues that the ＂pipeline＂, leading to the production and increase of undergraduate engineering and STEM （science, technology, engineering and math） related degrees by underrepresented student populations （which include female and AALANA （African American, Latin American and Native American） students）, has become more of a ＂fannel＂. After five decades of affu-mative action-oriented programs and laws, there is still a disconnect at most major research colleges and universities between the mnnber of these students entering into the various STEM related disciplines as freshmen and the total number that successfully complete the baccalaureate STEM degree. Current programs address superficial/peripheral issues related to diversity （i.e., recruitment）, but not the underlying sociological and anthropological aspects that lead to real solutions with permanent results （i.e., increased retention and graduation rates along with a more pluralistic campus environment where diversity is respected, celebrated and embraced in the STEM disciplines）. Thus, this paper suggests that a ＂multicontextual＂ model that emphasizes the latter will ultimately bridge this disconnect and achieve the more desirable ＂affirmative outcomes＂ that previous affirmative-action-oriented initiatives were originally put in place to accomplish.     

A genetic diversity comparison between captive individuals and wild individuals of Elliot＇s Pheasant （Syrmaticus ellioti） using mitochondrial DNA

Maintaining genetic diversity is a major issue in conservation biology. In this study, we demonstrate the differences of genetic diversity levels between wild and captive individuals of Elliot‘s Pheasant Syrmaticus ellioti. Wild individuals showed a higher genetic diversity level than that of the captive individuals. Nucleotide diversity and haplotype diversity of wild individuals were 0.00628 and 0.993, while those of captive individuals were 0.00150 and 0.584 respectively. Only 3 haplotypes of mtDNA control region sequence were identified among 36 captive individuals, while 16 unique haplotypes were identified among the 17 wild individuals in this study. One captive haplotype was shared by a wild individual from Anhui Province. It is concluded that a low number of founders was the likely reason for the lower level genetic diversity of the captive group. Careful genetic management is suggested for captive populations, particularly of such an endangered species, to maintain genetic variability levels.     

SSC： Gesture-based game for initial dementia examination

INTRODUCTION Dementia is becoming a big problem in modern life, and particularly, it takes place more frequently in mental job group and the elderly. Today, more than 20 million people in the world catch this disease (Francis et al., 1999; Almkvist et al., 1998). So how to detect underlying dementia and take preventive measure is critical for both the doctors and their patients. People with dementia always behave slowly and their memory decreases with the development of the disease. Curr…     

Modelling and control PEMFC using fuzzy neural networks

INTRODUCTION With worldwide increase of air pollution and the environmental consciousness of governments,people have to look for new resources to mitigate the energy crisis and improve the present environmental status(Baschuk and Li,2000;Rowe and Li,2001).Fuel cells are highly efficient and environmentally clean electricity generators(Berning et al.,2002)that convert the chemical energy of a gaseous fuel directly into electrical energy and play an important role in solving the energy pro…     

Feature-based multiresolution techniques for product design

INTRODUCTION 3D CAD systems for the feature-based B-rep solid models (Choi et al., 2002; Kim et al., 2003; 2005; Koo and Lee, 2002; Lee et al., 2004; Lee, 2005a) are becoming more suitable for CAD when compared with the conventional polygon-based mul- tiresolution modelling in computer graphics (Cignoni et al., 1998; Schr?der et al., 1992). As illustrated in Fig.1b, the object of the feature-based multiresolution modelling is a solid model where the suppressed ob- jects are form feat…     

A tetravalent single-chain variable fragment antibody for the detection of staphylococcal enterotoxin A

正Staphylococcal enterotoxin A (SEA) synthesized by Staphylococcus aureus is a foodborne and heatstable toxin, which is a great threat to human health (Pexara et al., 2010). Highly sensitive antibodies are a key factor in the immunological detection of SEA,which is one of the most effective ways to detect SEA because of its accuracy, agility, and efficiency (Nouri et al., 2018).     

Graph rigidity and localization of multi-robot formations

INTRODUCTION In order for a team of mobile robots to navigateautonomously in some desired formations and fur-ther perform cooperative tasks, such as surveillanceand target acquisition, they must be able to localizethemselves in the formation as well as in a globalreference frame (Belta and Kumar, 2001; Das et al.,2002). Therefore, how to estimate the robots’po-sitions and orientations (poses) in a precise andefficient way is of particular interest. Our interestwas in localizing a team o…

Homoharringtonine induces apoptosis of endothelium and down-regulates VEGF expression of K562 cells

INTRODUCTION Homoharringtonine (HHT) is a cephalotoxin alkaloid with anti-leukemic activity and had been used successfully in the treatment of acute and chronic myeloid leukemias (O払rien et al., 1995; 1999; Feldman et al., 1992). The principal mecha-nism of action by HHT is the inhibition of protein synthesis in a dose- and time-dependent manner by binding to ribosome and inhibiting polypeptide chain elongation (Tujebajeva et al., 1989; Zhou et al., 1995). HHT had been shown to indu…     

Why not Intercultural Education?

Now more than ever teachers and those in teacher training positions are being confronted with the prevalence of multicultural and multilingual classroom environments. Along with this presence, they also face international and national policies which call for effective and successful strategy building for coping with diverse settings. This appeal often manifests with an inability on the teacher＇s part to effectively facilitate these multicultural classrooms, as well as an inability on the students＇ part to interact and finally contribute to a larger national and global goal of intercultural cooperation. A growing body of research suggests that as those in the field of teaching and teacher education seek to improve classroom techniques, curricula, and teaching practice in the area of diversity they continue to face disparaging and almost disillusioning results. What were traditionally seen as venues in dealing with issues in multiculturalism and diversity through multicultural education have been left unanswered？ The purpose of this article thus seeks to explore the pedagogical concept of intercultural education as a way to suggest discourse of dealing with the challenges to diversity in the classroom.     

Audio steganalysis based on ＂negative resonance phenomenon＂ caused by steganographic tools

INTRODUCTION With the rapid progress in the Internet and ex- panded area of multimedia technology, steganogra- phy and steganalysis as subfields of information se- curity have developed rapidly and drawn more and more attention. Steganography is the art of hiding and transmitting data through apparently innocuous car- riers in an effort to conceal the existence of the secret data (Peticolas et al., 1999). While steganalysis, the countermeasure to steganography, is an art that de- tects ev…     

别秋赋

Introduction: As a British Consultant Engineer currently working for a large American engineering company in Yantai, China, specialising in Quality, it is somewhat surprising for me to find myself referred to as a poet it is even more incredible to have my poems published. My interests in life are travel and photography, both of which give me the opportunity to enjoy the diversity of life and cultures around the world.     

Application of Hilbert-Huang signal processing to ultrasonic non-destructive testing of oil pipelines

INTRODUCTION Ensuring the integrity and safe operation of oil pipelines network is critical for ensuring the trans- portation of one of the most important forms of en- ergy. An inspection vehicle, called intelligent pig, which employs ultrasonic non-destructive testing technique is often used to inspect oil transmission pipelines (Okamoto et al., 1999; Reher et al., 2002). The ultrasonic detection principle involves the fun- damental concept that a propagating wave will be reflected and/o…     

Adaptive modulation MIMO system based on minimizing transmission power

INTRODUCTION Many adaptive modulation (AM) schemes have been proposed for multi-input and multi-output (MIMO) and its derivations to increase the data throughput (June and Rao, 2002; Zhou and Vucetic, 2004a; 2004b; Chen et al., 2004; Zhou and Giannakis, 2004b). By using some kinds of greedy algorithms, all of these AM schemes try to maximize the trans-mission rate for a given transmission power. Their performances under different conditions have been studied deeply. The AM-MIMO w…     

Simulation study on fluctuant flow stress scale effect

INTRODUCTION With the continuous development of science and technology, especially the rapid progress of electronic industry and micromachine, microparts are needed more and more, and their technical requirements are higher and higher (Geiger et al., 1994; 1996; Geiger and Engel, 2002). However, traditional processing technologies, like cutting, etc., do not meet these requirements. Traditional plastic forming technology has merits like high production rate, excellent me-chanical proper…
