The complex dynamic characteristics of Quad-rotor Unmanned Helicopter (QUH) always lead to the difficulties in its modeling and control, which limit its development. Different methods for the modeling of QUH are studied carefully in this paper, and the physical modeling method and system identification modeling method of the QUH are given for comparison. Good advices of the selection for better modeling method are given in the end, which will be a good guidance for model selection of QUH in the future control system design.


The density of states for an ideal Bose gas in a γ -dimensional potential is obtained. Morever, the spatial distribution of particle numerical density is derived in the Thomas-Fermi semiclassical approximation. On this basis, the valid gain range of space for atom laser (that is the valid trapped range of ideal Bose gas in γ -dimensional potential) is given, and the influence of some important factors is also discussed.


This preliminary report deals with the parabiotic method of analyzing tissue homotransplantation compatibility. This method of transplantation was first conceived by Paul Bert' and actually developed as a technique by Sauerbruch and Heyde.2 Although animals surgically united in this way do a t times go into apparent successful union, each partner maintains its own organic functions and, to some extent, its own individual metabolism. I t has been shown by Huff et al.,3 K a m r i r ~ , ~ and other workers that the blood and tissue fluids pass continuously from one partner to the other. In successful parabionts there is gross evidence of the presence of large anastomotic connections in the connective tissues joining the two animals. Histological examination of the joined skin discloses continuity of the epithelium and a narrow connective tissue zonc of condensed fibers perforated by numerous capillaries. The extensive literature5, on parabiotic studies does not indicate the mechanism by which successful parabiosis is attained. T,oeb7 implies that the great dilution of each animal's fluids by its copartner will result in a tolerant gradient of each animal's "individuality differentials." Genetically, the work of Sne1I8 and his co-workers suggests that histocompatibility genes are present in both successful parabionts. In addition, the work of Eichwald et U Z . ~ would indicate that the male skin rejection phenomena by female recipients of the same strain is determined by a Y-linked gene. I t is further suggested by the authors "that hormonal mechanisms may modify a course of events largely determined by the distribution and strength of histocompatibility genes." The numcrous investigations of Billingham et u1.l" open the possibility that "actively acquired tolerance" as a specific inhibition of response is the immunological mcchanism that may favor successful parabiotic union. Unsuccessful parabiotic union is clearly manifested by (1) anemia and/or stunting of one of the parabionts, (2) death of one or both parabionts, ( 3 ) localized alopecia, (4) unhealed scar tissue in line of union, (5) formation of raw and oozing areas a t or near the line of union, and (6) slow or rapid separation of Lhe animals a t the original site of surgical union. When successful parabiotic union is obtained with pen-bred littermate albino rats, it is assumed that complete interanimal tolerance has been achieved. Since the blood cells, plasma, and tissue fluids are the major constituents exchanged and shared between the copartners, it is believed that any changes resulting from such mutual acceptance will be reflected in the distribution of the serum proteins. The present study deals with (1) the quantitative measurements of the blood serum components in single arid sham-operated animals and in successfully


A pigeonpea ( Cajanus cajan L. Mills) stem cutter was developed in the department and its performance was evaluated in the field. During testing of equipment the problem were observed in the transmission of power from PTO to cutter unit and conveying of cut plant. Thus, modification of power transmission system of the equipment was carried out in the department of Farm Power and Machinery, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Among with the modification in power transmission system, the conveying system was also modified. The cut plant were bending in opposite direction of travel during the conveying and getting chocked between the conveying tray and cutting unit. In view to avoid this a plant guiding arrangement was introduced on the equipment. The modified pigeonpea stem cutter was tested in the field at the operating speed of 3 and 3.5 km/h. and was found working satisfactory. The cutting efficiency of the modified implement was increased due to the change in position of cutter bar and efficiency of conveying was improved tremendously with the modification of conveying tray and introduction of plant guiding arrangement. The maximum cutting efficiency was found 81.25 per cent and 80.00 per cent at 3 km/h and 3.5 km/h speeds, respectively. Whereas the field efficiency was observed as 72.59 per cent and 74.28 per cent at the above mentioned speeds, respectively. The plant damage was found 10.29 per cent and 10.93 per cent at 3 km/h and 3.5 km/h speed of operation, respectively. The cost of operation was observed 42.07 per cent less as compared to the manual harvesting of the pigeonpea crop.


In the application of 3D reconstruction of the road surface of highway or runway,a method of attitude angle measuring based on disappear point lookup was proposed to revise the 3D reconstruction result.The heading angle and pitching angle were gained by picking-up the road's disappear point in the photograph of forward view,then with the velocity information of the car,the vehicle's track can be gained.At last,the 3D reconstruction result can be revised by the information of vehicle's track,and then the 3D appearance of the road surface can be gained.The experiment showed that the attitude angle gained by this method arrived at a high precision and the 3D appearance of the road surface inosculated well with the actual road surface.


During the next 25 years, there will be a 25% increase in the atmospheric concentration of CO/sub 2/. This will contribute to global warming, only partially off-set by particulate screening in the Northern Hemisphere. The CO/sub 2/ and the warming trends will be reinforced by continued deforestation in the tropics because biomass up-take and oceanic absorption are the principal outlets for atmospheric CO/sub 2/. These phenomena are a common concern of industrial countries producing CO/sub 2/ and aerosols from combustion of fossil fuels and agricultural countries contributing dust from arid lands and CO/sub 2/ from wood burning. World-wide monitoring of the changes must be improved. Ground stations in remote locations should measure CO/sub 2/ and particulate concentrations. Remote sensing should be used to measure deforestation and reflectivity. Mathematical models will be useful tools for analysis but they cannot replace continuous, large-scale monitoring.


Abstract : The analysis of powered lifting systems of the jet flap type requires an accounting of the mutual aerodynamic interference between the airframe (hard boundary) and the jet efflux (soft boundary). The development of a very generalized analysis technique is hardly feasible. However, the Externally Blown Flap (EBF), Upper Surface Blowing (USB), Internally Blown Flap (IBF), and the Augmentor wing (AW) consititue a family of powered lifting systems which are reducible to a common overall aerodynamic concept, but which differ primarily in their mechanical implementation and secondarily in aerodynamic detail. This report presents a relatively simple technique based on careful application of linearized theory. The method applies to the analogous systems mentioned above. The comparison of theoretical results with experimental data shows that the method is sufficiently accurate to be very useful in practice.


Due to the advantages of high efficiency, low mass, modularization and high power density, the step-up resonant converter is widely adopted in providing kV-level high voltage for the ion propulsion power supply. As a key part of the resonant converter, the resonant tank topology is evaluated in this paper. Based on the characteristics of the high-voltage resonant converter, a selecting criteria for the resonant tank is proposed. Applying the criteria to the 2-element, 3-element, and 4-element resonant tank topologies, the candidate for high-voltage application can be recommended. Then, the selected topologies are compared based on the relationship between voltage gain and frequency. The analytical results show that the gain valley could be more easily founded in the 4-element resonant tank compared with others, thus it is more suitable for the high-voltage application.


We have studied a 43-year-old man with azoospermia. Chromosome analysis, using G-, Q-, and C-banding techniques, showed a dicentric 46,X,i(Yq) chromosome abnormality. The clinical, cytogenetic, endocrine, and testicular histologic findings are presented. The case is discussed in relation to the pertinent literature. This represents the first phenotypic male with this karyotype ever reported.


The objective of the study was to examine the effect of supplier relationship management (SRM) on competitive advantage of commercial banks in Kenya. A survey research design was adopted to collect data from sample size of 78 employees drawn from 4 commercial banks using Random sampling was used in selecting the respondents. Data was collected by the use of questionnaires administered by the researcher. The collected data was analyzed using descriptive data analysis through computer based statistical package on social sciences and inferential statistics by use of regression model. This was done at 95% confidence level and 5% percent marginal error. Study results showed that quality improvement and lead time reduction has a positive and significant effect on competitive advantage. However, sufficient efforts were not directed towards the purchasing process and joint decisions regarding the supplied products. Based on this research and literature review, it is still perceived that all the factors are equivalently related to increased competitive advantage. Since the current research was limited to commercial banks operating in Kenya, there was a limited sample available from the population. It was recommended that a replication study to be done to augment the findings of

According to a news release dated 16 April 2005, recent experimental data from JLAB, the Thomas Jefferson National Accelerator facility in Newport News, Virginia, USA point to the absence of the pentaquark called Θ, at the place where it was expected. This surprising result due to the CLAS collaboration (where CLAS stands for the CEBAF Large Acceptance Spectrometer; CEBAF stands for the Continuous Electron Beam Accelerator Facility, which was the name of JLAB) contradicts the findings of several prior experiments, including some of its own, which indicated that at least one kind of pentaquark exists in the mass range 1525–1555 MeV/c (for a review, see Hicks), while none of the experiments could definitively prove its existence. This recent experiment was based on a high energy photon beam on a liquid hydrogen target. It had considerably greater statistics; in fact, two orders of magnitude greater than a similar experiment in Germany carried out by the SAPHIR collaboration at the ELSA (Electron Stretcher Accelerator) in Bonn, which had seen evidence for the existence of pentaquarks. At JLAB, work is continuing in the hunt for pentaquarks with even higher statistics, and the data are being analysed with the possibility of publication of results later this year. The CLAS collaboration is likely to gather more data in 2006 by searching for other pentaquark candidates. The aim of the experiments which are being discussed here, has been to establish the existence of a new state of matter. For a long time, it was believed that all observed matter at the subatomic level, that participates in the strong interactions comes in only two families. These are the 'baryons' and the 'mesons', collectively known as 'hadrons'. For instance, protons and neutrons which are constituents of all nuclei, belong to the baryon family, while, for instance, pions which are responsible for inter-nucleon forces, belong to the meson family. Baryons are made up of three constituent quarks, while mesons are bound states of quarks and anti-quarks. Quarks themselves come in several 'flavours', socalled u (up) and d (down), s (strange), c (charm), t (top) and b (bottom) quarks. The neutron, for instance, is made up of two d and one u quark, while the proton is made up of two u and one d quark. Note that the u quark has a charge of +2e/3, while the d quark has a charge of –e/3, where –e is the electronic charge. Pions can be one of π, π or π. π, for instance, is made up of a u quark and an anti-d quark. Of interest to us here are also 'strange' mesons, which could contain either a strange or an anti-s quark, called kaon. For instance, a K contains a u quark and an anti-s quark. Today we have a microscopic theory of strong interactions known as quantum chromodynamics (QCD), for the interactions of 'coloured' quarks and gluons (the mediators of the strong force). The word 'colour' pertains to an internal quantum number and comes in three varieties, which have been named red, blue and green. However, this quantum number is never directly observed, and it is believed that only 'colourless' objects are found in the spectrum of QCD. Closely related is the hypothesis of 'confinement', which requires the quarks and gluons to be confined inside the hardronic matter, and the colour quantum number itself is never liberated. As a result, a quark which carries a colour and an anti-quark that contains 'anti-colour' can bind through the exchange of gluons which carry both colour and anti-colour to form a meson. Similarly, quarks containing each of the three primary colours can produce a colourless object. It is for the moment impossible to solve the dynamics of the theory, which has in its spectrum the baryons and mesons. Therefore, novel theoretical tools and models have to be invoked in order to gain an insight into the spectrum. In the year 2003, several experiments reported evidence for a new state of matter in the subatomic realm which had been named 'pentaquark', where the particle was believed to have been composed of four quarks and one anti-quark, an arrangement compatible with the generation of a colourless object. There was tremendous excitement since mathematically such particles were the prediction of several theoretical groups working on hadron dynamics. Notable amongst these was that of Diakonov, et al., who had also predicted the mass and the lifetime of a family of pentaquarks by considering a certain effective model of the strong interaction dynamics subject to certain plausible assumptions, known as the chiral soliton model. This model itself is too technical to be discussed in simple words, but is one in which conventional baryons are viewed as the lowest rotational states in the spectrum, while the pentaquarks appear as the next rotational state of 'chiral solitons', with the Θ predicted to have a mass of 1530 MeV/c. For a recent review on the theory and other models of interest, see Oka. Indeed, it is mathematically possible also to have configurations with two quarks and two anti-quarks (tetraquarks), three quarks and three anti-quarks (hexaquarks), etc. These would also constitute exotic hadronic matter. The first experiment to claim evidence for the pentaquark is the SPring-8 experiment in Japan. The experimental facility is at an electron synchrotron, LEPS, where electrons at an energy of 8 GeV scatter laser photons which are then used as projectiles for collision with carbon nuclei. The process is described by the reaction


Recent research works have shown that control statistics based on squared deviation of observations from target have the ability to monitor variability in both univariate and multivariate processes. In the current research, the properties of the control statistic St that has been proposed by Huwang et al. (J. Quality Technology 2007; 39:258–278) are first reviewed and three new St‐based multivariate schemes are then presented. Extensive simulation experiments are performed to compare the performances of the proposed schemes with those of the multivariate exponentially weighted mean squared deviation (MEWMS) and the L1‐norm distance of the MEWMS deviation from its expected value (MEWMSL1) charts. The results show that one of the proposed schemes outperforms the others in detecting shifts in correlation coefficients and another has the best general performance among the compared charts in detecting shifts in which at least one of the variances changes.

TWENTY years have elapsed since Ohsawa1(cited by Bird2) first successfully resected the esophagus for carcinoma and reestablished gastrointestinal continuity, a procedure introduced into this country by Adams and Phemister3in 1938. Limited at first to resection of carcinoma of the gastric cardia and to lesions of the lower esophagus, the range of operability was markedly extended in 1944 by Garlock,4who suggested transplantation of the esophagus above the arch of the aorta and the establishment of an anterior anastomosis between the stomach and the esophagus. As would be expected, the main surgical interest during these years was focused upon problems of operative technique. Due chiefly to the extensive experiences of Garlock,5Sweet,6Strieder,7Payne and Clagett,8and others, certain technical details have become established and the operative hazards decisively lowered, the net result being an increase in the resectability rate accompanied


cally) either at the time of surgery or radiation therapy. The plain radiograph of the chest now showed a right hilar opacity. Flexible fibreoptic bronchoscopy revealed a mass in the right main bronchus just beyond the carina, probably an endobronchial metastasis (EBM). Histopathology was confirmed as squamous cell carcinoma. He underwent chemotherapy but subsequently died of pulmonary complications. EBM from extra-pulmonary solid malignant tumours are rare and virtually unknown in squamous cell carcinoma tongue. The diagnosis of EBM is now increasing because of the regular use of fibreoptic bronchoscopy.1 Sugarbaker and colleagues2 have suggested the tumour cell entrapment hypothesis (dissemination of malignant cells from trauma). Pickhardt and co-workers3 have described the metastatic implantation at the percutaneous endoscopic gastrostomy tract. They further state that evidence points to direct tumour implantation during endoscopic placement as the likely cause rather than hematogenous spread. Airway instrumentation has been known to cause trauma to various soft tissues of the upper airway and aspiration of solid material to the lung has been described.4 The right main bronchus is known to be the most common site of aspiration and this was the site of EBM in our patient. Direct tumour implantation during surgical dissection is unlikely to have occurred since the airway was protected with a cuffed tracheal tube. Our opinion is divided between a second primary (carcinoma lung) and a metastasis (EBM from carcinoma tongue) because it is difficult to distinguish histopathologically or immunohistochemically between these entities. Kawada and others5 report a similar case, but they suggested that the single endobronchial lesion was considered to be a second primary tumour. In our patient, a secondary tumour was considered more likely because of the documented trauma to the tumour before surgical excision. We conclude that direct tumour implantation into the lower airways during anesthesia is a possibility that should be investigated and ruled out by further clinical investigations.


The access control systems (ACS) are useful to improve the Quality of Service solutions. These systems are generally based on delay, jitter or packet loss, employing more of these criteria to maintain the required quality of service requiring for voice or video sessions. We propose an ACS that employs packet loss between probes that send an end-to-end test stream before accepting additional sessions. We used Ethernet as our transport network because the 803.3ae is widely used in metropolitan area networks. This paper presents how the ACS will interoperate with MPLS and describe the improvements related to its use in a metropolitan Ethernet network.


Tanon Tourism Village is located in Dusun Tanon , Ngrawan Village, Getasan District, is one of the developing tourist villages in Semarang Regency. The Tanon Tourism Village was pioneered in 2009 and began to be formalized in 2012 as an embryo of a tourism village in Ngrawan Village. The development of the tourism village which has occurred for more than 10 years has influenced the physical and non-physical aspects of the village. The influence on physical aspects for example is the change in land, while the influence on non-physical aspects for example, on the economy of the community. So, this study aims to determine the effect of the presence of Tanon Tourism Village on the economy and land use. The method used is quantitative by using descriptive statistics and image analysis methods. Through the research results, it is known that its influence on the economic aspects is to encourage the desire to try, create employment opportunities, namely the creation of various jobs related to tourism village activities, as well as increasing the income earned every month. While the effect on land changes is a change in land use and land to meet the demand of accommodations and supporting facilities for tourism activities.


The hemagglutinating and hemolytic activities of Fusobacterium necrophorum biovar A strains were stable during 100 subcultures on agar medium. Therefore, the term "biovar" should be used instead of "phase" for F. necrophorum.

Scanning transmission electron microscopy (STEM) was used to examine sintered and hot-pressed aluminum-doped silicon carbide; grain boundary segregation of Al was observed in both materials. Semiquantitative analysis was carried out on the Al-saturated hot-pressed material. An estimated heat of segregation between 116 and 174 kJ/mol was calculated from the STEM data and equilibrium segregation theory. Strain energy as a driving force was considered negligible. The data are consistent with a segregation model in which the driving force for segregation is the difference in the nature of bonding between the solute and solvent atoms. Fast grain boundary diffusion of Al was suggested from a loss of Al during heat treatments.


Crystallographic orientation of the MgO barrier in sputter-deposited CoFeB/MgO/CoFeB magnetic tunnel junctions (MTJs) and its effect on tunnel magnetoresistance (TMR) were investigated. The degree of MgO(001) orientation was estimated with the integral intensity ratio (I (200) /I (220)) of diffraction lines from MgO(200) and MgO(220) planes obtained in grazing incident x-ray diffraction profiles. The main results are stated as follows. (1) I (200) /I (220) ∼ 4, meaning the (001) orientation of MgO, is realized when the underlaid CoFeB maintains amorphous structure, meanwhile MgO on bcc(110)-oriented CoFe shows (111) orientation (I (200) /I (220) = 0). (2) The prevention of epitaxial growth on hcp(00.1)-oriented Ru layer is effective to maintain amorphous structure of CoFeB. (3) The achievable TMR ratio after high temperature (280 °C − 450 °C) annealing is mainly dominated by the MgO orientation and giant TMR ratio exceeding 200% is only obtained with I (200) /I (220) ≥ 3.4, while the resistance area product is independent of I (200) /I (220). (4) Thin Mg layer inserted between CoFeB layer and MgO barrier is effective to obtain bcc(001)-oriented crystallization of CoFeB after high temperature annealing and results in a giant TMR ratio, because of its role to avoid surface oxidization of underlying ferromagnetic electrode during the deposition of MgO barrier.

The non-traditional security concerns pose a serious challenge to both the developed and the developing nations alike, health security being one of them. Health is not an independent variable. It is inter -wined with social, economic, environmental and cultural aspects. Not only are these causes behind raising issues related to health but also, happen to be important determinants behind the access, availability and affordability of resources, policies, programmes directed towards enhancing of health security. Without addressing the problems of poverty, illiteracy, malnourishment, irrational and unscientific approach, all measures to improve upon the quality of health enjoyed by people cannot give desirable results. Objective of the Study – The present study is an attempt to- a) Understand Health Security, its need and importance. b) Compare and contrast the health indicators of India and Japan, which reflect the extent of health security enjoyed by peo ple in their respective nations. c) Make an analysis of the projected health indicators by making a special reference to the socio-economic determinants that play a vital role in enhancing health security. Methodology- The study is based on both quantitati ve and qualitative data accessed from secondary sources, viz. books, research papers from various journals both e -journals and print journals are consulted. Various official websites of not only India and Japan but also, of various international bodies and organizations are referred for procuring both the types of data.


OBJECTIVE
To search for immunomodulators to improve postburn immune function disorder.

METHOD
We studied the Chinese medicinal herbs. On the basis of previous data, we prepared a kind of Chinese medicinal herbal mixture and studied its effects in vivo and in vitro.

RESULT
The mixture could restore the cell-mediated immune response such as the production of interleukin 2 and the T cell proliferative ability, and could also adjust the levels of serum acute-phase reaction proteins, i.e, haptoglobin, prealbumin, transferrin and alpha 1-acid glycoprotein.

CONCLUSION
The Chinese herbal mixture showed immune regulatory effects on body defence imbalance and also on acute phase reaction proteins in burn patients.


This paper develops and evaluates a BPMN-based process model which identifies and extracts blog content from the web and stores its textual data in a data warehouse for further analyses. Depending on the characteristics of the technologies used to create the weblogs, the process has to perform specific tasks in order to extract blog content correctly. The paper describes three phases: extraction, transformation and loading of data in a repository specifically adapted for blog content extraction. It highlights the objectives in these phases which must be achieved to ensure the correct extraction. The authors integrate the described process in a previously developed framework for blog mining. The authors' process model closes the conceptual gap in this framework as well as the gap in current research of blog mining process models. Furthermore, it can easily be adapted for other web extraction proposals.


"David had begun work on The Loves of Paris and Helen in 1786, and had originally intended to have it ready for the 1787 Salon. However, due to an injury to his achilles tendon sustained in October 1786, and a long illness in 1787, the work was not completed until 1788. The Loves of Paris and Helen was a work on a new theme for David, and to express the amorous nature of the subject, David greatly modified the uncompromising and severe style of his previous paintings. The two figures are smooth and sculptural and are bathed in subtle light. David took great trouble over the details in this painting of courtship and physical attraction. A statue of Venus, goddess of love, is placed on a column at the left, and we also see two wreaths of myrtle, an evergreen sacred to Venus and an emblem of conjugal fidelity. The painting examines the differing emotions that Helen feels towards Paris because, according to Homer's account in the Iliad, Paris won Helen over even though he had been defeated in combat by her husband Menelaus. This seduction had the tragic consequence of starting the Trojan War. Helen stands, her head inclined, attracted by the handsome Paris yet still harboring doubts. Paris' passion is understated and simply suggested by the gentle grasping of Helen's arm. For added, although incorrect, detail in the background, David included four caryatids. In this present work, David went to great lengths to show his versatility and to demonstrate that he was not just a painter of heroic and masculine scenes." (Simon Lee, "David", p. 116-119)


Crystal structure of potassium [[2-[2-[2-[2-[2-[2-[2-(2-hydroxyethoxy)phenoxy]ethoxy]phenoxy]ethoxy]phenoxy]ethoxy]phenoxy]methyl]benzoate (2) has been determined. The backbone forms pseudocycle by head-to-tail hydrogen bonding. Conformations about C–C and C–O bonds are gauche and trans respectively, except for two of the C–O bonds which are gauche to make the pseudocyclic backbone bend like seam of a tennis ball. Ten oxygens except for one of the benzoate group coordinate with the potassium ion.


Handling cache related preemption delay (CRPD) in a preemptive scheduling context for real-time systems stays an open subject despite of its practical importance. Priority assignment algorithms and feasibility tests are usually based on the assumption that preemption cost is negligible. Then, a system that could be schedulable at design time can fail to meet its timing constraints in practice due to preemption cost. In this article, we propose an elementary approach to take into consideration the CRPD while assigning priorities to tasks. The goal is to acquire a priority assignment algorithm guaranteeing the schedulability of the system when its tasks suer CRPD at run-time.


The problem facing the British economy is to curb inflation, reduce the deficit on the balance of payments, now running at £4,000 million a year, raise company profits to improve new capital investment, improve efficiency and productivity and to contain wage demands. The competitive power of British exports in the world will depend to a large extent on labour costs and managerial competence. Labour costs largely depend on the attitudes and actions of the trade unions, and in full employment their power is considerable. It can have far reaching social and economic effects. Their failure in the past two decades to readjust their philosophy, their organisations and institutional arrangements, created in times of mass unemployment, to conditions of full employment is partly the reason for the present state of industrial relations: backward, inward looking and divisive.

An effective and flexible data conversion controller for ink jet printing is proposed in this paper. It provides the capability of processing firing data to meet the requirements of both firing sequence and firing timing of the cartridge. This print data is arranged according to the nozzle layout of a selected print cartridge and the printing direction. Then output the arranged data to the firing driver of print cartridge. A hardware architecture is proposed to serve the needs of data conversion. It is an effective design that consists of two appointed selections of nozzle firing sequence and fixed nozzle pad mapping. Moreover, the proposed architecture provides programmable firing timing and it can be switched between black or color printing mode. The core technology of this data conversion hardware is now applied to an ASIC of ink jet fax engine by OES/ITRI.


Textbooks material is one of the important issues that are worthy to investigate in order to enrich student's engagement and interaction in EFL (English as a Foreign Language) classrooms. In this study, the author argues that textbooks materials used in academic institutions may well take a significant part in generating an active environment in EFL classrooms. It is believed that more opportunities will be created for students to be more involved, active, and able to understand the content being addressed more effectively. Yet, by looking at the textbooks being utilised (at a university context where the author teaches), one can notice that student's culture (Eastern)  is  to a  large extent missing  in these textbooks, most of  these books  instead represent  dominantly  "Western"  culture  namely  American  and  British  cultures.  This  can  clearly  be  depicted  by  topics discussed,  pictures,  clothing,  names,  and  many  other  issues  portrayed  in  these  textbooks.  This  study  is  an  attempt  to challenge  and  problematize  such  domination  of  Western  cultures  portrayed  in  the  content  of  English  textbooks  used  in academic institutions not merely within Saudi Arabia but also extended to other countries and nations in the world.

Despite the strong interest in Polish-Czechoslovakian relations between 1918‒1939, the subject of desertions during this period from the Polish Army to Czechoslovakia, and vice-versa, has so far not been examined in detail by Polish historians. This article attempts to identify the similarities and differences that existed among deserters from the respective Armies. In addition to presenting the history of these deserters, this study also considers the causes and consequences of these military desertions.


Recognition of motion sequences is a crucial ability for biological and robot vision systems. We present an architecture for the higher-level processes involved in recognition of complex structured motion. The work is focused on modeling human recognition of Moving Light Displays. MLDs are image sequences that contain only motion information at a small number of locations. Despite the extreme paucity of information in these displays, humans can recognize MLDs generated from a variety of common human movements. This dissertation explores the high-level representations and computational processes required for the recognition task. The structures and algorithms are articulated in the language of structured connectionist models. The implemented network can discriminate three human gaits from data generated by several actors. .pp Recognition of any motion involves indexing into stored models of movement. We present a representation for such models, called scenarios, based on coordinated sequences of discrete motion events. A method for indexing into this representation is described. We develop a parallel model of spatial and conceptual attention that is essential for disambiguating the spatially and temporally diffuse MLD data. The major computational problems addressed are: (1) representation of time-varying visual models; (2) integration of visual stimuli over time; (3) gestalt formation in and between spatially-localized feature maps and central movement representations; (4) contextual feedback to lower levels; and (5) the use of attention to focus processing on particular spatial locations and particular high-level representations. Several novel connectionist mechanisms are developed and used in the implementation. .pp In particular, we present advances in connectionist representation of temporal sequences and in using high-level knowledge to control an attentional mechanism. We show that recognition of gait can be achieved directly from motion features, without complex shape information, and that the motion information need not be finely quantized. We show how the "what" and "where" processes in vision can be tightly coupled in a synergistic fashion. These results indicate the value of the structured connectionist paradigm in modeling perceptual processes: no previous computational model has accounted for MLD recognition and we do not know how it would be approached in any other paradigm.


Abstract : Civil Affairs has been employed throughout America's history. Civil military operations were used in the Mexican-American War, Spanish-American War, WWI and II, and Vietnam before Bosnia. In each conflict civil military capabilities were developed. After these conflicts civil military expertise dissolved and were left to figure out how to deal with civilian population. This paper examines Civil Affairs in Bosnia. Bosnia lies on the cross roads of empires and religions. Bosnia was at ground zero of regional power struggles. These events affected the population leaving scars to be exploited by leaders. Politicians could make peace among the people or create wars, as in Bosnia. This war eventually caused the UN, the international community, and NATO to get involved. The Dayton Accords ended the fighting, requiring NATO to deploy IFOR. IFOR succeeded in winning peace, but needed to transition to SFOR to maintain peace. Civil Affairs came to the forefront during the Bosnian War. CA's efforts were successful, but some areas needed improvement. In every engagement there is a lesson to be learned, in Bosnia it was the value of Civil Affairs. There will be other Bosnias in our lives.-Richard Holbrooke, End of War

Many recent studies of older people have been concerned with the validity of the theory of disengagement. Briefly stated, this theory assumes that disengagement is an inevitable process associated with aging "in which many of the relationships between a person and other members of society are severed, and those remaining are altered in quality." The theory further assumes that ego energy declines with age, and that as persons age they experience increased self-preoccupation and presumably decreased response to normative controls. Data from a nationwide sample study of persons aged 65 years or more permit comparisons of the attitudes of successive age cohorts from age 65 to 69 to age 85. The findings indicate that with advances in age, old people in the United States apparently do become increasingly preoccupied. On the other hand, there seems to be no evidence from the data for the decrease in response to normative controls also suggested by the theory. The data suggest that most old people harbor weak or non-existent age group identifications, and that most old people are optimists. A key question seems to be whether the present findings are associated with aging in a particular culture, the United States, or whether they have a more general application.


ESR investigations show that two‐photon excitation and x irradiation of nominally pure LiNbO3 crystals at 20 K create electrons, which are self‐trapped as Nb4+, and holes, which are captured at acceptor‐type defects as O−. The radiation‐induced absorption at low temperatures is attributed to these centers. The trapped electrons and holes play an important role in the two‐photon‐induced photorefractive process.


Subvenous epicardial fat tissue (SEAT), which acts as an electrical insulation, and the venous diameter (VD) both constitute histomorphological challenges for optimal application and lead design in cardiac synchronization therapy (CRT). In this study, we characterized the morphology of human coronary veins to improve the technical design of future CRT systems and to optimize the application of CRT leads. We retrospectively analyzed data from cardiac computed tomography (CT) of 53 patients and did studies of 14 human hearts using the postmortem freeze section technique and micro CT. Morphometric parameters (tributary distances, offspring angles, luminal VD, and SEAT thickness) were assessed. The left posterior ventricular vein (VVSP) had a mean proximal VD of 4.0 ± 1.4 mm, the left marginal vein (VMS) of 3.2 ± 1.5 mm and the anterior interventricular vein (VIA) of 3.9 ± 1.3 mm. More distally (5 cm), VDs decreased to 2.4 ± 0.6 mm, 2.3 ± 0.7 mm, and 2.4 ± 0.6 mm, respectively. In their proximal portions (15 mm), veins possessed mean SEAT thicknesses of 3.2 ± 2.4 (VVSP), 3.4 ± 2.4 mm (VMS), and 4.2 ± 2.8 mm (VIA), respectively. More distally (20–70 mm), mean SEAT thicknesses decreased to alternating low levels of 1.3 ± 1.1 mm (VVSP), 1.7 ± 1.1 mm (VMS), and 4.3 ± 2.6 mm (VIA), respectively. In contrast to the VD, SEAT thicknesses alternated along the further distal vein course and did not display a continuous decrease. Besides the CRT responsiveness of different areas of the LV myocardium, SEAT is a relevant electrophysiological factor in CRT, potentially interfering with sensing and pacing. A sufficient VD is crucial for successful CRT lead placement. Measurements revealed a trend toward greater SEAT thickness for the VIA compared to VVSP and VMS, suggesting a superior signal-to-noise-ratio in VVSP and VMS.


1 ABSTRACT Design projects draw on a broad range of knowledge and skill areas for successful completion. However, in most landscape architecture curricula the rigid structure of faculty assignments and course descriptions prevent learning outcomes that allow students to experience the impact of multiple skill areas in shaping solutions. Rather, students operate within "silos" of information without adequately drawing the connections between subject areas that are necessary to achieve a systematic design solution. Furthermore, because students don't consider the ways in which one knowledge area influences the others, and the refinements that result, student design solutions can be one-dimensional. Realizing an opportunity, the faculty of Purdue University's junior-level courses in design, grading and drainage, plant materials, and construction documents began seeking a single project that would allow the students to integrate material from all of these courses in a single project. This paper describes a project process created by the authors to combat these inherent drawbacks of the traditional curricular structure. Rather than simply using a common site to achieve individual course outcomes, the authors sought a fully integrated experience that would emulate a professional's process and enrich the end product. The paper will explore the process created and propose opportunities for programs with like curricula structures to implement similar integrated project experiences, and will include preliminary data gathered. Further data and analysis on the results of this particular methodology to follow once a reasonable sample size is collected.


The use of recently developed high brightness subpicosecond lasers for the study of the interaction of solid matter is leading to the production of powerful incoherent X-ray sources associated with dense plasma environments. The use of these intense pulsed X-ray sources will enable the production of extremely high densities and levels of electronic excitation in materials while leaving the system kinetically cold during the interaction. This general condition is extremely conductive to the amplification of short wavelength radiation. The analysis of a particular case for amplification at a quantum energy of about 1 keV indicates that a total energy of about 1 J of ultraviolet radiation is necessary for excitation. The control of this class of physical processes is expected to lead to a new generation of amplifiers in the X-ray range.

ATV (all-terrain vehicle) riding continues to be popular in rural mountainous areas of southeastern Kentucky, southwest Virginia, and northeast Tennessee. Many ATV riders are injured while riding in an unsafe manner, riding unhelmeted, or under the influence of drugs and alcohol. Death, disability, and trauma center admissions from ATV crashes have persisted nationwide in recent years. Trauma centers in Tennessee frequently see ATV riders injured in other states with variable ATV helmet safety laws that are poorly enforced, with few wearing a helmet and many intoxicated. ATV safety laws regarding helmet use, alcohol involvement, and roadway riding are poorly enforced or largely ignored. We hypothesized that direct surgeon funding and leadership in injury prevention and research would decrease ATV crashes in their respective communities. To focus prevention efforts, we reviewed a rural Level I trauma center's 10-year experience with ATV crashes, comparing helmeted and unhelmeted ATV crash rider outcomes. For the last five years of the study (since 2013), our injury prevention fund has sponsored injury prevention educational events at high schools in our trauma center catchment areas in northeast Tennessee, southwest Virginia, and southeastern Kentucky. We used an electronic driving simulator and customized go-carts and "drunk goggles" to simulate operating an ATV while intoxicated, emphasizing helmet use and responsible off-road ATV riding operations to all high school students. Students were given a completion certificate. We sponsored billboards and TV commercials and supported the "Safe Communities of America, Sullivan County, Tennessee, designation through the National Safety Council. We lobbied state legislators and the state governor regarding universal helmet laws for ATV riders. A trauma registry review of ATV admissions from 2008 through 2018 examined demographics, helmet use, and clinical outcomes using chi-square, t test, and regression analysis (Table 1). Six hundred thirty-three ATV crashes were seen at a rural Level I trauma center in Upper East Tennessee over a 10-year period from January 1, 2008, through January 1, 2018. There were 383 (60% of total) injured ATV riders seen in the early time period (2008–2013) and 250 (40% of total) ATV riders in the later time period (2013–2018). The average age was 35 years. There were 21 deaths during this 10-year period (3.3%). Unhelmeted ATV riders suffered more severe head and neck injuries odds ratio (OR) 19, confidence interval (CI) 1.5–1.8, P < 0.001), worse overall Injury Severity Score (ISS) (OR 25, CI 12.1–14.2, P < 0.001), and higher mortality rates (OR 4.0, CI 0.02–0.05, P < 0.001). Unhelmeted ATV riders had longer hospital and ICU lengths of stay (P < 0.001). Although only 15 per cent of riders were helmeted throughout the study period, ATV crash admissions have decreased in the last five years (P < 0.001). ATV crashes from Kentucky were more numerous and suffered higher mortality rates (P < 0.001) (Table 2). ATV rider fatalities whowere injured in Kentucky were younger and included more females than those from Tennessee or Virginia (P < 0.001). In a systematic review of 28 studies by the Eastern Association for the Surgery of Trauma, helmet use when riding an ATV reduced the rate of traumatic brain injury (TBI). ATV safety legislation, when enforced, also reduced morbidity and mortality.1 Compliance with laws is often low, however, possibly because of poor enforcement. Helmet use is recommended when riding on an ATV to reduce traumatic brain injury. The Eastern Association for the Surgery of Trauma study group recommends implementing ATV safety legislation as a means to reduce ATV injuries, noting that enforcement must go hand in hand with enactment to ensure compliance.

Generating response with both coherence and diversity is a challenging task in generation-based chatbots. It is more difficult to improve the coherence and diversity of dialog generation at the same time in the response generation model. In this article, we propose an improved method that improves the coherence and diversity of dialog generation by changing the model to use gamma sampling and adding attention mechanism to the knowledge-guided conditional variational autoencoder. The experimental results demonstrate that our proposed method can significantly improve the coherence and diversity of knowledge-guided conditional variational autoencoder for response generation in generation-based chatbots at the same time.


Abstract A sensitive and selective method for the extraction and spectrophotometric determination of Zr(IV) with N-p-chlorophenyl-3,4-,5-trimethoxycinnamohydroxamic acid (PTCHA) has been developed. The binary complex of Zr(IV)-PTCHA is extracted from 2–6 M HCl into chloroform, having a maximum absorbance at 385 nm; molar absorptivity 2.1 × 104 1 mol−1 cm−1. A ternary complex with xylenol orange (Zr-PTCHA-XO) have been studied in chloroform-ethanol media, which absorbs at 540 nm; molar absorptivity 4.3 × 104 1 mol−1 cm−1. The present method is applied for the analysis of zirconium in standard samples.

The design and construction of an ion source designed for the MS‐9 mass spectrometer are described. The source is designed to operate at ion chamber pressures up to 2 Torr while the pressure in the remainder of the source housing does not exceed 2×10−4 Torr. It is possible with this source to study ion‐molecule reactions, i.e., chemical ionization mass spectrometry. Alternatively, if operated at lower ion chamber pressures, the source provides normal electron impact mass spectra and is thus a dual‐purpose source. Modifications necessary to the MS‐9 are described, as are performance characteristics of the new source.


Results are reported from a simulation of the interaction between the solar wind and the earth magnetosphere, using a time-dependent three-dimensional MHD model. The calculation was performed for several orientations of the IMF between dawnward pointing and southward. When the IMF has a dawnward component, the plasma sheet rotates northward on the dawnside of the tail and toward the south on the duskside. As the southward component becomes larger, the plasma sheet becomes thinner and develops a wavy cross section because of patchy or localized tail reconnection. The field-aligned currents (FACs) associated with this localized reconnection have a filamentary layered structure. When projected onto the polar cap the filamentary FACs are located in the same region as the tail region 1 currents. At lower latitudes strong region 2 sense currents that originate in the plasma sheet are found. FACs are found on field lines that map to the polar cap even for southward IMF. These currents have many of the properties of the observed polar-cusp currents. The polar-cusp FACs evolve from the polar-cap NB(z) FACs as the IMF is rotated from northward to southward.


AbstrAct The XML Messaging Protocol, a part of the Web service protocol stack, is responsible for encoding messages in a common XML format (or type), so that they can be understood at either end of a network connection. The evolution of an XML type may be required in order to reflect new communication needs, materialized by slightly different XML messages. For instance, due to a service evolution, it might be interesting to extend a type in order to allow the reception of more information, when it is available, instead of always disregarding it. The authors' proposal consists in a conservative XML schema evolution. The framework is as follows: administrators enter updates performed on a valid XML document in order to specify new documents expected to be valid, and the system computes new types accepting both such documents and previously valid ones. Changing the type is mainly changing regular expressions that define element content models. They present the algorithm that implements this approach, its properties and experimental results.


Multicomponent ultrafine particles are very promising to fabricate advanced and fine materials. In the present study the preparation method of multicomponent ultrafine particles containing Y and Ce was investigated. The stock solutions were prepared with YCl3, Ce (NO3)3, EDTA, urea and distilled water. The particles were precipitated from the solutions using the homogeneous precipitation method. The generator of the precipitants was urea. It was a characteristic point that EDTA was used for a condition modifying reagent. The reaction temperature and the reaction time were 97°C and 120 min, respectively. Y/Ce ratios in the precipitates was considerably different from the ratios in the original solutions. These phenomena may be attributed to the difference in the stability between Y-EDTA and Ce-EDTA. The ultrafine particles containing Y and Ce equivalently were precipitated from the solution in which Y/Ce was three. Those multicomponent ultrafine particles were almost spherical. The average particle size was 57 nm and the particle size distribution was apreciably narrow.

Correct perception of weight status is an important motivational factor for engaging in healthy behaviors, such as physical activity and making acceptable nutrition choices. However, misperception is common in the population.


Objective To study the mechanism of the Carbapenems-tolerance in Pseudomona aeruginosa(P.aeruginosa). Method Thirty-one strains of P.aeruginosa isolated from November 2008 to April 2009 in our hospital were analyzed.According to the results of drug sensitivity test,the thirty-one strains of P.aeruginosa were divided into Carbapenems-tolerance group(21 strains) and Carbapenems-sensitive group(10 strains).Meanwhile,a standard strain of P.aeruginosa ATCC 27853 was also studied and an imipenem-EDTA inhibition test was conducted to detect metallo-beta-lactamases.PCR method was used to detect the oprD2 gene in P.aeruginosa,so as to study the mechanism of the Carbapenems-tolerance in P.aeruginosa.Result 7 of 21 strains of Carbapenems-tolerance P.aeruginosa produced metallo-beta-lactamases;15 of 21 strains of Carbapenems-tolerance P.aeruginosa were shown to be oprD2 gene negative,while the other 6 were positive.In contrast,all of the 10 strains of the Carbapenems-sensitive P.aeruginosa were found to be oprD2 gene positive,and so was the standard strain ATCC 27853.The results of the Chi-square test revealed that the difference between the positive rates of the oprD2 gene in the Carbapenems-tolerance and sensitive P.aeruginosa was statistically highly significant.Conclusion Loss of the oprD2 gene and metallo-beta-lactamases-producing ability were the important mechnisms of the Carbapenems-tolerance in P.aeruginosa of our hospital.


By using a current that has a triangular waveform, students can investigate how the voltage across a field coil is related to the current. The inductive effects are seen to be proportional to the slope of the current, and the effects of resistance are clearly evident. The coil used has an inductance of 3.9 mH and a resistance of 1.3 Ω. An inexpensive circuit for producing a triangular wave is presented. It is assumed that students are familiar with the law of magnetic induction and that they can use an oscilloscope as a test instrument.


GDS What were your early influences? I was influenced by the nineteenth century novelists, not so much by poetry. I haven't read a great number of modern novels. I've been exposed to and read a certain amount of modern Australian and American poetry. I was influenced by French writing. I was interested in Conrad, Jane Austen, the Bronte sisters. Italo Svevo. I used to love Nathaniel Hawthorne when I was a teenager. I liked the stuff that dealt with really emotional things. I went through a long period of reading drama, Ibsen, Shakespeare, O'Neill. That was the reading that I could find in libraries when I was younger. I found a few other people when I was older, like Christina Stead. I'd been writing poetry but I hadn't been able to write the way I wanted to write and I felt the kind of stuff I was reading wasn't the way I wanted to write either. There wasn't anything I read that struck a chord in me. But then I read some modern American poetry and Robert Creely's prose. They were French influenced. Then I looked at the French stuff. This material was presented to me by Ken Bolton. This body of reading startled me and made me realise there was a modern tradition which I could slip into more easily. Robbe-Grillet, Marguerite Duras. They presented me with a new way of writing, and looking. I wasn't so much influenced by other Australians as realising later on that I had a lot in common with some of them.


: Hydro generator design is a significant issue in terms of safety, efficiency, and energy production sustainability. One of the most crucial issues about design criteria is to satisfy the needs of the project's critical speed. In this work, the critical speed calculation of an 11 MW hydro power plant was investigated with several design steps. Numerical solution methodologies were implemented using ARMD™. A generator design was developed, and the implementation of the rotor was carried out in Antalya, Turkey. Vibration and displacements of the hydro generator are adequate. The generator unit is active for 3 years and have never encountered runaway speeds. No critical speed or resonance speed is anticipated for the designed hydro generator unit.


Flav-2-enes, flavones, and 3-alkyl ethers of flavonols add alcohols and carboxylic acids in the presence of N-bromosuccinimide to give 2-alkoxy- and 2-acyloxy-3-bromoflavans which provide routes to cis-3-bromoflavans by reduction and to 3,4-diols by elimination and reaction with osmium tetraoxide. The 2-acyloxyflavans react with alcohols yielding 2-alkoxyflavans. Flavonols react with N-bromosuccinimide and alcohols to give bromine-free hemiacetals, the known 2,3-dialkoxy-3-hydroxyflavanones.


In this paper, enormous soil samples were collected and analyzed,meanwhile Geographical Information System(GIS)and Geostatistical analysis were used to study the spatial variability of the cropland soil properties in Shawan County,Xinjiang.The results showed that soil organic mater(12.4 g/kg) and available potassium(195.3 mg/kg) content were decreased,while alkali- hydrolyzale nitrogen(86.7 mg/kg) and available phosphorus(16.2 mg/kg) content were increased that compared with the results from the Second National Survey of China in 1980 s.The soil nutrients were characterized by moderate variation,the ratio of the nugget value and sill value was between 0.25 to 0.75,indicating the medium- sized space dependence.In the study area,most of the soil's alkali- hydrolyzale nitrogen content were between 60 mg/kg to 90 mg/kg,which accounted for67.93% of the total research area;available phosphorus content was between10 mg/kg and 20 mg/kg which accounted for74.98%;the soil available potassium was more than 150 mg/kg,which accounted for94.85 % of the total research area; organic mattercontent was between 10 g/kg to 20 g/kg,which accounted for71.21%,of the regional area.The results could provide a theoretical basis of reasonable fertilization forthis county.


In last few decades the development of hybrid electric two-wheelers is mainly focused on the reduction of on road emissions produced by these vehicles. As these vehicles have added cost and complexity hence resulted in the failure of these systems to meet consumer expectations. This report presents a comparative study of the energy economy and development of a hybrid electric two-wheeler vehicle so that the efficiency of small two-wheelers such as scooters or low capacity motorcycles can be improved. The projected model is modified from a 125cc Engine combined with 72V, 18A heavy duty BLDC electric motor of 2KW power, having 645 RPM at no load to further enhance the overall fuel efficiency of the system, particularly the fuel consumption rate. To prove the enhancement in the efficiency of a traditional motor scooter is the main function/utility of this model. Many technologies like regenerative generation, electric motor drive, automatic start or shut off are also used in hybrid two- wheeler vehicles to make them as efficient as conventional vehicles. Though hybrid vehicles have electric motor and battery, they are can fueled like conventional vehicles as they use IC engine. At other side they can be partially or wholly powered by electricity.


This study examined the frequency, morphological and immunohistochemical characteristics of the giant fibres in the longissimus muscle of local Krško polje pigs with different Ryr1 genotypes. Giant fibres were round‐shaped and had significantly increased cross‐sectional area compared with normal muscle fibres. Only fast‐twitch glycolytic fibres were affected, usually showing enhanced succinate dehydrogenase activity. On the ultrastructural level, the dilation of the sarcoplasmic reticulum, swelling of mitochondria and destruction of myofilaments was observed. The incidence of giant fibres was the highest in Ryr1 dimutant pigs (Ryr1 nn), which also exhibited lower muscle pH1 than heterozygous (Ryr1 Nn) or pigs with the wild Ryr1 gene (Ryr1 NN). However, the giant fibres were also present in pigs free of Ryr1 gene mutation. Our results suggest that the giant fibre syndrome depends mostly upon the rate and intensity of early post‐mortem glycolysis, which results in acidity of muscle tissue. We suppose that the giant fibre formation is a result of excessive intracellular lactate accumulation in some fast‐twitch glycolytic fibres. This process could also explain the ultrastructural alterations and the consequent changes in the oxidative enzymes and myofibrillar ATPase staining pattern observed in our and some previous studies.

This paper is concerned with decentralized tracking-type games for large population multi-agent systems. The individual dynamics are described by stochastic discrete-time auto-regressive models with exogenous inputs (ARX models), and coupled by terms of the unknown population state average (PSA) with unknown coupling strength. A two-level decentralized adaptive control law is designed. On the high level, the PSA is estimated based on Nash certainty equivalence (NCE) principle. On the low level, the coupling strength is identified based on decentralized least squares algorithms and the estimate of PSA. The decentralized control law is constructed by combining NCE principle and certainty equivalence principle. By probability limit theory, under mild conditions, it is shown that: (a) the closed-loop system is stable almost surely; (b) as the number of agents increases to infinity, the estimates of both PSA and the coupling strength are asymptotically strongly consistent and the decentralized control law is an almost sure asymptotic Nash-equilibrium.


The Quaternion Numbers In this article, we define the set H of quaternion numbers as the set of all ordered sequences q =  where x,y,w and z are real numbers. The addition, difference and multiplication of the quaternion numbers are also defined. We define the real and imaginary parts of q and denote this by x = ℜ(q), y = ℑ1(q), w = ℑ2(q), z = ℑ3(q). We define the addition, difference, multiplication again and denote this operation by real and three imaginary parts. We define the conjugate of q denoted by q*' and the absolute value of q denoted by |q|. We also give some properties of quaternion numbers.


A two-dimensional numerical model is developed to predict the time variation of bed deformation in alluvial channel bends. In this model, the depth-averaged unsteady water flow equations along with the sediment continuity equation are solved by using the Beam and Warming alternating-direction implicit scheme. Unlike the present models based on Cartesian or cylindrical coordinate systems and steady flow equations, a body-fitted coordinate system and unsteady flow equations are used so that unsteady effects and natural channels may be modeled accurately. The effective stresses associated with the flow equations are modeled by using a constant eddy-viscosity approach. This study is restricted to beds of uniform particles, i.e., armoring and grain-sorting effects are neglected. To verify the model, the computed results are compared with the data measured in 140° and 180° curved laboratory flumes with straight reaches up- and downstream of the bend. The model predictions agree better with the measured data tha...


The high-energy lepton collider TESLA can be operated in the GigaZ mode on the Z resonance, producing a billion Z bosons per year. This will allow the measurement of the effective electroweak mixing angle to an accuracy much better than one part in 10,000. Similarly, the W boson mass is expected to be measurable with an error of 6 MeV near threshold. We discuss the impact of these observables on the accuracy with which the Higgs boson mass can be determined from loop corrections within the Standard Model. We also study indirect constraints on new mass scales within the Minimal Supersymmetric Standard Model.

In 8 conscious cats the dynamical relationship between Baroreflex Sensitivity vs. Respiratory Sinus Arrhythmia was indirectly estimated from the analysis of intra-arterial blood pressure tracings. A good parallelism was found between the two variables while less evident links were observed between Respiratory Sinus Arrhythmia and Respiratory Frequency.


Rapture Untold: Gender, Mysticism, and the 'Moment of Recognition' in Works by Gertrude Stein analyzes patterns within Stein's language, revealing the nature and origin of religious ideas in her work, particularly those texts written during the 1920s. By viewing Stein's texts in light of recent feminist criticism, theories of gender and reading, and Stein's influence on the French feminists and Language poets, it may be possible to re-envision the process of reading Gertrude Stein.

The parasitic resistance is studied to silicon/metal contact junction for improving device performance and to lower contact/serial resistance silicide in natural sequence. In this paper constructs the stepwise Ni silicide process for parasitic resistance reduction for silicon/metal contact junction. We have investigated multi-step Ni silicide on SiGe substrate with stepwise annealing method as an alternative to compose more thermally reliable Ni silicide layer. Stepwise annealing for silicide formation is exposed to heating environment with for 10 seconds and a dwelling for both 10 and 30 seconds, and ramping-up and the dwelling was repeated until the final annealing temperature of is achieved. Finally a direct comparison for single step and stepwise annealing process is obtained for 20 nm nickel silicide through stepwise annealing is at , and it is 42 % lower than that of as nickel sputtered. The proposed stepwise annealing for Ni silicidation can provide the least amount of NiSi at the interface of nickel silicide and silicon, and it provides lower resistance, higher thermal-stability, and superior morphology than other thermal treatment.


Individual tree segmentation is essential for many applications in city management and urban ecology. Light Detection and Ranging (LiDAR) system acquires accurate point clouds in a fast and environmentally-friendly manner, which enables single tree detection. However, the large number of object categories and occlusion from nearby objects in complex environment pose great challenges in urban tree inventory, resulting in omission or commission errors. Therefore, this paper addresses these challenges and increases the accuracy of individual tree segmentation by proposing an automated method for instance recognition urban roadside trees. The proposed algorithm was implemented of unmanned aerial vehicles laser scanning (UAV-LS) data. First, an improved filtering algorithm was developed to identify ground and non-ground points. Second, we extracted tree-like objects via labeling on non-ground points using a deep learning model with a few smaller modifications. Unlike only concentrating on the global features in previous method, the proposed method revises a pointwise semantic learning network to capture both the global and local information at multiple scales, significantly avoiding the information loss in local neighborhoods and reducing useless convolutional computations. Afterwards, the semantic representation is fed into a graph-structured optimization model, which obtains globally optimal classification results by constructing a weighted indirect graph and solving the optimization problem with graph-cuts. The segmented tree points were extracted and consolidated through a series of operations, and they were finally recognized by combining graph embedding learning with a structure-aware loss function and a supervoxel-based normalized cut segmentation method. Experimental results on two public datasets demonstrated that our framework achieved better performance in terms of classification accuracy and recognition ratio of tree.

The present study deals with the reconstruction of the continuous-time state space parameters proper of human quiet standing. The reconstruction utilized a hybrid non-linear extended Kalman filter to combine a biomechanical model with the discrete-time position measurements provided by two web-cameras via a General Linear Camera model. After camera calibration and validating the filter in simulation, we performed the estimation on a group of volunteers whose quiet standing was perturbed by means of a hold and release paradigm. The filter allowed estimating stiffness and damping of the ankle during quiet standing as well as the kinematic variables of the subjects' center of mass.


Myeloproliferative neoplasms (MPNs) are clonal disorders of hematopoietic stem cells and are divided according to the presence of a Philadelphia chromosome/ BCR-ABL fusion (Ph 1 ) as chronic myeloid leukemia (CML) and Philadelphia chromosome negative (Ph 2 ) MPNs [1]. In the majority of classic (Ph 2 ) MPNs (polycythaemia vera (PV), essential thrombocythaemia (ET) and primary mye-lofibrosis (PMF)), the Janus kinase 2 JAK2 V617F mutation is detected with frequencies of (cid:1) 95% in PV and 50% in ET and PMF [1], whereas it is generally absent in Ph 1 MPNs [1]. Nevertheless, it is known that ''overlap'' syndromes between these classifications occur, as eight cases of Ph 1 MPNs with concomitant JAK2 V617F mutations have been reported, all of which, however, belonged to the entity of classic MPNs [2]. In contrast, we have found evidence for a Ph 1 CML with a concurrent JAK2 V617F positive myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN), specifically a refractory anemia with ringed sideroblasts and marked thrombocytosis (RARS-T) that defines a subentity of an MDS/MPN unclassifiable with detection of the JAK2 V617F mutation in (cid:1) 50% of cases [3]. The 67-year-old male patient presented with spleno-megaly, leukocytosis (38.000/ l l), and an


Objective: To explore the inhibitory effect of curcumin on colon cancer in vitro. Methods: Human colon cancer cell lines HT29 and SW620 were cultured in vitro, which were divided into test group and control group. Cells in the test groups were treated with curcumin at different concentrations, while the control groups were treated with dimethylsulfoxide (DMSO). Subsequently, methyl thiazolyl tetrazolium (MTT) assay, were carried out to estimate cellular proliferative activity. Flow cytometry using annexin-V/ propidium iodide (PI) staining was performed to detect cell apoptosis. Formation of autophagosomes in the cytoplasm in colon cancer cells were detected by TEM (transmission electron microscopy analysis), and Western blot to measure the expressions of proteins related to apoptosis and autophagy. Results: MTT assay showed that curcumin inhibited the proliferative activity of both HT29 and SW620 cells, significantly different from the control group (P<0.001). The halfmaximal inhibitory concentration (IC50) of curcumin at 24 hours was 20μM for both HT29 and SW620 cells. Annexin-V FITC/PI double labeling showed that, After treatment with curcumin of 20μM for 24 hours, a significant increase was observed in apoptosis rate in both HT219 cells ((10.00 ± 0.60)% vs. (4.00 ± 0.70)%, P<0.01; (10.50 ± 0.40)% vs. (4.30 ± 0.26)%, P<0.01) compared with the control cells. TEM analysis showed that curcumin increased the accumulation of autophagosomes in the cytoplasm in HT29 and SW620 cells. Western blot showed an increase in the expressions of apoptosis-related proteins including cleaved caspase-3 and cleaved poly ADP-ribose polymerase(PARP) but decrease of P62 protein in both HT29 and SW620 cells after 24-hour treatment with 20μM curcumin for 24 hours compared with the control groups. Conclusion: Curcumin can inhibit the proliferation, induce apoptosis and autophagy in human colon cancer cells.


which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Background: Acinetobacter baumannii, an opportunistic nosocomial pathogen that can cause significant morbidity and mortality , has emerged as a worldwide problem. The aim of this study was to evaluate the risk factors for mortality in patients with A. baumannii bacteremia. Materials and Methods: We retrospectively evaluated 118 patients who had A. baumannii bacteremia between July 2003 and December 2011. The aim of this study was to identify the 30-day mortality in patients with A. baumannii bacteremia and relevant risk factors. Results: The bacteremia-related 30-day mortality rate was 34.1%. Univariate analysis revealed that the risk factors for mortality included malignancy, longer hospital stay before bacteremia, intensive care unit (ICU) stay at the time of bacteremia, mechanical ventilation, use of a central venous catheter, unknown origin of bacteremia, bacteremia due to pneumonia, antimicrobial resistance to carbapenems, and elevated Acute Physiology and Chronic Health Evaluation II and Pitt bacteremia scores. Multi-variate logistic regression analysis revealed that resistance to carbapenems (odds ratio [OR]: 4.01, 95% confidence interval [CI]: 1. were significantly related to mortality risk. Conclusions: Risk factors such as resistance to carbapenems, mechanical ventilation, and presence of malignancy were found to be associated with high mortality rates in the patients with A. baumannii bacteremia.


In the framework of the Myocean EU (FP7 and Horizon 2020) funded projects, Mercator Ocean, the French operational oceanography center, is in charge of the development and of the production of real time analysis and forecasts and reanalysis for the global ocean at the resolution of 1/12°. The operational systems are all based on the ocean and sea ice model NEMO and the multivariate data assimilation system SAM2 (Système d'Assimilation Mercator V2). The assimilation method is a reduced order Kalman filter based on SEEK/LETKF formulation with an Incremental Analysis Update. The background error covariance is represented by an ensemble of multivariate state vectors defining a subspace of the control space. However, the SAM2 background error statistics are built using a static approach based on a prior long multi-year free simulation. In order to better represent the errors of the day, a more realistic description of the uncertainties is necessary and could be reached from ensemble simulations using stochastic modeling. In this work, a twin-experiment is carried out introducing elements of an Ensemble Kalman Filter, to assess ocean uncertainties in a high-resolution Bay of Biscay configuration. The experimental protocol presented here serves as an intermediate step in the evolution of Mercator Océan data assimilation systems, towards a Local Ensemble Transform Kalman Filter (LETKF). Initially, a long-range ensemble is performed, by applying stochastic modelling of the wind forcing. The target of this step is to simulate the envelope of possible realizations in a regional configuration and to evaluate the robustness of the method on building ensemble background error covariances. Sensitivity assimilation experiments explore the relative performance of the ensemble approach, in order to identify somes parameters of the method in future operational systems. First results indicate that the ensemble method outperforms in many cases operational methods using static covariances in the chosen experimental protocol. Thus, finding efficient methods to capture the most important aspects of ocean uncertainty is of high priority for the near future.

This chapter aims to quantify more exactly the adoption of broadband at the household level in Chile by assessing its impact on three types of digital divide: between users and nonusers of the Internet, between usage at home and elsewhere, and between home broadband users and modem home users. This was done by a statistical analysis of WIP-Chile surveys of 2003 and 2006. At least in Chile, the main digital gap is still between users and non users of the Internet, both in terms of age and education level. Income mainly affects the probability of having broadband access at home. Since broadband has rapidly expanded among all socioeconomic segments, it is becoming less relevant as a predictor of access and Web usage. Other factors are also weak predictors of both residential use of the Internet and broadband connections at home. New data and surveys are required to clarify the point.


While face verification technology is proving its value on the security of smartphones, it finds a more suitable environment of implementation than on desktop computers. Targeting to the "close-range frontal" photos taken by the front camera of smartphones, an efficient face verification approach is proposed in this paper. A dedicated rule-based algorithm is first implemented to detect four facial feature points which are used to align the input face images and partition the face region into four components. Based on each group of facial components obtained from the training dataset, an eigen subspace is constructed through principal component analysis(PCA). Finally the weighted sum of correlations between each input face component and its back-projection onto the subspace is calculated to measure the similarity of the input person against that in the dataset. Experiments are conducted on a dataset with 464 face images taken from 9 persons with variable illumination, background and expression. The Experimental results prove a 98.2% of accuracy on feature detection, a 8.5% of EER on face verification and the computational time being less than 0.8 seconds on a personal computer.


This study aims to explore the attitude of social welfare service providers to cooperatives and to evaluate the potential impacts of introduction of cooperatives on the social welfare service sector. To better understand issues, we surveyed social welfare and social service institutions which provide social welfare services in Gyeonggi province. A questionnaire was developed and distributed to the CEO of the institutions and, as a result, the total number of 384 CEO participated in the survey. The main findings of the survey are as follows: among the institutions of social welfare service, the level of awareness of the Framework Act on Cooperatives reached 40-46%. However, 14-18% of social welfare service institutions have intention to organize cooperatives. Social welfare institutions prefer a social cooperative to a general cooperative if have any chance to organize a cooperative. The results of survey imply that the short term impacts of the Framework Act on Cooperatives on the social welfare service sector would be marginal although the impacts would be positive.

Shift work is known to have a number of negative effects on the life and health of employees. It can lead to the disorganization of social and family life as well as many psychophysiological problems that can affect health in the long term. Moreover, it is likely to favour the development of eating habits which do not meet the requirements of general health standards. It is well known, for instance, that a positive correlation exists between the number of years spent employed on shift work and the occurrence of obesity. This type of work schedule could influence eating habits, thus contributing to obesity by either modifying the diet (i.e. introducing unhealthy food) or by producing abnormal food intake schedules. The main purpose of this study was, therefore, to focus on the relationship between eating habits and work schedules, as a function of possible sleep-wake cycle modifications due to shift work, as well as on possible specific motor activity. Twenty-eight nurses volunteered to participate in this experiment. Subjects were divided into four groups as a function of weight (obese/normal) and work schedules (shift work / normal). Motor activity was measured by means of an actimeter over a period of 14 days and nights. These objective measures were then correlated with subjective assessments on qualitative and quantitative information concerning eating habits and sleep quality. These measures were completed with qualitative ratings and affective reactions produced by obesity.
The actimetric results suggested evidence of a specific difference in the motor activity of obese workers compared to normal weighted workers, namely hypo-activity. Questionnaires also showed different eating habits and sleep quality in obese shift workers as compared to the other groups. Namely, the frequency of nibbling between main meals was significantly higher in this group than in obese nurses working on regular day schedules and in normal weighted shift workers. This group was also the one which assigned the cause of obesity to stressful activity and which attributed to it the origin of their negative affect. However, there was no evidence of a specific diet in obese subjects, ruling out, at least under our experimental conditions, the possibility that food characteristics by themselves could participate to the development of obesity. In conclusion, this study suggests that obesity in shift workers could be mainly due to abnormal schedules of food intake rather than to the nature of the diet alone.


Ultrafast endoscopic optical coherence tomography is demonstrated based on inertia-free time-stretch mechanism. Images of finger skin and intravascular stent are obtained with a line-scan rate of ~11.5 MHz to showcase its capability in endoscopic bioimaging.


The modelling of new information technologies usage behaviour is of great interest to managers who need to evaluate the probability of success in the introduction of these technologies. This study empirically tests the capacity of Davis's Technology Acceptance Model (TAM) (Davis, 1989) and Davis et al.'s Motivational Model (MM) (Davis et al., 1992) to help understand the determinants of the intention to use the internet to search for holiday information. The findings show that these theories do explain the intention of internet use by the tourist.


Calcium and magnesium are known to influence the quantity of acetylcholine (ACh) that is released by impulses in cholinergic nerves. Thus the output of acetylcholine from the superior cervical ganglion during stimulation of the preganglionic trunk is reduced when the perfusion medium is deficient in calcium (Harvey & MacIntosh, 1940) or when it contains excess magnesium, and is increased when the medium contains calcium in excess of the usual amount (Hutter & Kostial, 1954); and there is electrophysiological evidence indicating that these two ions have similar antagonistic effects on the release of acetylcholine from motor nerve endings in skeletal muscle (del Castillo & Katz, 1956). The present paper offers evidence that barium, a divalent ion closely related to calcium and magnesium, also influences acetylcholine release from cholinergic nerves. A preliminary account of the findings was presented at the meeting of the Physiological Society in Lund last July (Douglas, Lywood & Straub, 1960).


The biological activities of phenolic compounds from olive mill wastewater (OMWW) have been extensively studied. However, the bioactivity of raw OMWW has not been yet well demonstrated in vivo. The objective of this study was to evaluate the effect of oral administration of OMWW on cafeteria diet induced metabolic disorders in rats. Our results showed that within a 13-week treatment period, the cafeteria diet induced an increase in glucose and triglycerides levels. The levels of glucose, triglycerides and the total cholesterol were significantly decreased after supplementation with OMWW (p < 0.05). To evaluate the toxicity effect of OMWW, the results concerning the blood parameters of the renal and liver function (urea, creatinine, uric acid, bilirubin, total protein and transaminases) showed that there are not difference between the control and the OMWW supplementation groups. The liver histology from rats fed with cafeteria diet showed a steatosis which is characterized by lipid droplet accumulation in the hepatocytes cytoplasm. In OMWW supplemented groups, the liver tissue showed a structure similar to the control group.  HPLC analysis of OMWW reveled the major presence of a phenolic acid wich is hydroxytyrosol. In conclusion, our study suggests that OMWW brought real health benefits by protecting liver tissue and modulating some biological parameters such as lipid parameters
