The theoretical analysis is made for the induced current and voltage which occurs on double circuit transmission lines on the same tower.Then the analysis results are proved through calculation using EMTP.The inductive effects of 500 kV conventional tower and compact tower are studied contrastively.And the relationships between induced current,induced voltage and some factors,such as line length,transmission power,shunt reactor,and so on are studied.The conclusion can be extended to the lines of other voltage levels.So the research result is valuable for the designing and maintenance of double circuit transmission lines.


The discrimination between the intrusion and the nuisance events without compromising sensitivity is a key performance parameter for any outdoor perimeter intrusion detection system.In certain circumstances,the signals of the intrusion and the nuisance events are almost the same.This is especially the case for the intrusion and the nuisance events which may have a similar impact.In this paper,a series of methods are proposed to extract the fiber-signals:to denoise the input signal based on the wavelet transform;with a new practical algorithm of pre-segmentation of the fiber-signal,based on the hypothesis that the distribution of the energy of the intrusion in the time domain is different from that of the nuisance;to generate the eigenvector extracted from the distribution of the energy in the wavelet space;and to classify the fiber-signal using the support vector machine.With the assumption that different kinds of fiber-signals have different energy distributions in each frequency,the results of this experiment are satisfactory.This method is practical because we may take advantages of the SVM with very small cost.


We examine the excitation of spin-wave eigenmodes in the vortex state of microsized ferromagnetic circular dots made of Permalloy (Ni{sub 81}Fe{sub 19}) both theoretically and experimentally using Brillouin light scattering microscopy. We report on the detection of the radial spin-wave eigenmodes of single elements with high mode number (up to n = 13 for the largest disk radius 2.5 {mu}m). Theoretically we obtain an equation for the eigenfrequencies valid for arbitrary dot aspect ratios (thickness/radius) within the magnetostatic approximation. We demonstrate the influence of the disk radius on the spatial mode profiles, in particular, changes in the pinning of the dynamical magnetization at the edges and in the center of the disks. The measured spin-wave eigenfrequencies are in good agreement with our calculations for the disks with different radii.


The influence of firing conditions on the mineralogical composition of clay base ceramics is studied. Experimental samples fired in oxidation atmosphere at temperature rates 850, 900, 950, 1000 and 1050 C o with respect to high amount of CaO in raw materials (Ave. 18.76 %), these samples classified in Ca-rich clay group. The determination of chemical composition, phase structure and mineralogy were carried out by thin section petrography through Pol. Microscopy, XRF, XRD with Rietveld refinement method, TGA and mercury immersion porosimetry. The results show that the amount of quartz and the percentage of porosity are diminished with increasing of temperature. The presence of gehlenite, diopside, augite and wollastonite at 850 C o and fassaite (at 950 C o ) are demonstrated formation of firing products. The results suggest that quantitative investigation on mineralogical changes and the co-existence of phases in experimental specimens, can provide appropriate pattern for estimating firing temperature and technology of archaeological potteries.

Constant-velocity (CV) joints have become standard design and an integral part of modern vehicles, primarily due to their superiority in terms of CV torque transfer. Despite widespread usage of constant velocity joints there are certain aspects of their friction, wear, and contact characteristics that are not well understood. In this article, the need to directly measure CV joint internal contact and friction forces is addressed by designing and constructing an instrumented advanced CV joint friction apparatus using actual tripod-type joint assemblies. The apparatus is capable of measuring key performance parameters such as friction and wear under different realistic operating conditions of oscillatory speeds and CV joint articulation angles. The apparatus incorporates a custom-installed triaxial force sensor inside of the CV joint to measure in situ internal CV joint forces (including friction). The CV joint apparatus is under full computer control and is communicating with all measurement components via a master Labview control program. Experiments under different articulation angles and lubrication conditions were performed and the measurements were correlated with published data.

The purpose of this study is to investigate the influence of knowledge management infrastructure and process on nursing care effectiveness in selected teaching hospitals in Southwest Nigeria. The organization of nursing knowledge resources is critical to health care organizations for providing safe and high quality care for patients. Therefore, it is necessary to study the role of knowledge management in clinical nursing practice and the outcomes on the effectiveness of nursing care. Despite the critical role of nursing care in defining high-performing health care delivery, knowledge management in this area is still at an early stage of development. Based on organizational capability theory and employing concurrent mixed-method research design, this study seeks to identify the components of knowledge infrastructure and processes that influence the efficiency and effectiveness of nursing care in clinical floor nursing of selected teaching hospitals in Nigeria, a developing country in Africa. The output from the research is expected to contribute to the domain of literature/knowledge; provide awareness of the knowledge management practices in nursing care in Nigeria; assist nursing administrators, health policy makers and hospital management to exploit and make effective use of knowledge-based resources to enhance nursing care which can improve the productivity of health care organizations.


Learning Student Community is a group organization founded by students themselves in order to cultivate high-quality talents with moral,intellectual,physical and aesthetic education under the guidance of "people-oriented" educational theory.It relies on students′ majors and arouses their enthusiasm.On the basis of the characteristics of university learning community and signification of its construction,this paper provides some references for the healthy development of the current college communities by illustrating how to determine the community development goals,regulate its internal management,enhance exchanges and co-operations with other communities,as well as build the evaluation system for capacity improvement.


A geometric structure factor is introduced to study the dispersion relation of phonon in mesoscopic structures. Due to the finite size effect, phonon modes are discrete and degenerated. With decreasing the size of the structures, the interval between two discrete modes are enlarged and the degeneracy of each mode is enhanced. Basing on the discrete phonon modes, the size effect on thermal conductivity $\kappa$ has been obtained, showing that $\kappa$ is decreased with the decreasing of the size and converges for structures infinite in size.


This authors,aims at researching the influence from irrigation of different Cd water density(0.04,0.08,0.10,0.12,0.20,0.24 mg/L) on rice quality and soil through barrel plant and soil culture.Compared to CK,it showed that,Cd mainly stayed at the depth of 5-20 cm of the soil and that the density of Cd obviously restrained the stem length of rice and 1000-grain weight decreased.However,there were no obvious effects on number of grain per ear and yield per plant.Though different Cd water density restrained the appearance of rice and milling quality,these features could achieve the green rice requirement,and nutritional quality was of no affection,protein and amylose content could reach the standard and there was no difference compared to CK.The higher irrigation density was,the more Cd would stay in soil,and so did Cd in rice.Most of the Cd would remain in soil after irrigating,the detains was 99.3%,73.8%,60.4%,55.5%,37.4%,47.6%.According to these data,it could be concluded that the lower density of Cd in water used for irrigation,the more Cd would be absorbed by soil,and the higher density was,the less would be absorbed.When Cd desity was higher than 0.20 mg/L,the content of Cd in white rice reached its standard(0.2 mg/kg),which meant that density of Cd in water used for irrigation should be lower than 0.20 mg/L.


The point that this paper addresses is a point—and I hope to show this in the following pages—that is of vast importance in certain narratives of the foundation of modernity. Although this foundation has accumulated more narratives than can be counted, it remains convenient and productive to return to Descartes' narrative of the ascension of human reason, particularly as expressed in the Discourse on the Method (1637). The point I would like to raise here has been considerably less recognized than the narrative itself—but it is, as I hope to demonstrate, utterly essential to the latter. It concerns the extensively glossed juxtaposition of Montaigne and Descartes as inaugural of modernity. I wish to underscore the facts that in all his writings the rationalist makes but a single explicit reference to his predecessor, and that this reference has everything to do with Descartes' demarcation of


A conservative approach was taken in selecting process instrumentation and controls for the Syncrude tar sands refinery in N. Alberta, emphasizing ease of installation and maintenance rather than optimum throughput or efficiency. Conventional analog pneumatic and electronic instruments were used almost exclusively. Problems arose in spite of the precautions taken, caused by factors ranging from design changes made by the vendors to oversights in providing for future expansion.


This paper presents a comparison between different artificial intelligence techniques used for finger spelling recognition on a real-time system, with emphasis on Support Vector Machines and Artificial Neural Networks but also using other wellknown methods. The comparison is based on the computational complexity, correct rate and time taken to process the required information. The tests are based in two models of ANN and a binary tree structured multi-class SVM. The results show that SVM has an equivalent recognition rate as ANN and it is computationally cheaper and faster than ANN.


Objective samples from normal semen parameters. Patients and method: Prospective study conducted from January 2010 to January 2011, which studied 22 couples who attended the Specialized Center Sterility and Human Reproduction, Hospital Angeles Mexico City, to undergo intrauterine insemination with sex selection. The couples were divided into two groups: A: couples with primary infertility who wanted to take advantage of intrauterine insemination for sex selection, and B: couples with secondary infertility where the cause of intrauterine insemination with sex selection was for social or cultural reasons. The two groups of patients underwent a protocol of ovulation induction with menotropins follicle ® Results: 22 couples undergoing intrauterine insemination with sex selection were divided into two groups: A (n = 8) and B (n = 14), not-recruitment of many follicles, but the growth of two or three follicles of high quality. Conclusions technique of this work is derived from the technique developed by Ericsson, we propose four miniswim make-up of 15 min instead of increasing concentrations of albumin in the culture medium, so, the results are similar to those obtained.


The Wiggins-Holmes extension of the generalized Melnikov method (GMM) is applied to parametrically forced cross-waves in a long rectangular channel in order to determine if these cross-waves are chaotic. A great deal of effort is required in order to obtain a suspended system for the application of the GMM. The Lagrangian for surface gravity water waves is transformed to surface integrals in order to eliminate constant conjugate momenta. The Lagrangian is simplified by subtracting the zero variation integrals and is then expressed in terms of generalized coordinates given by the time dependent components of the cross-wave and progressive-wave velocity potentials. The conjugate momenta and the Hamiltonian are computed by the Legendre transform of the Lagrangian. The first-order differential equations obtained from derivatives of the Hamiltonian are usually suitable for applications of the GMM. However, the cross-wave Hamiltonian contains a variation in the third direction (3.3c) that is 100% non-autonomous...


This thesis analyzes German immigration to Canada in the period following the Second World War and primarily focuses on the settlement of these immigrants in Vancouver. By examining residential patterns, economic experiences, the role of German churches and Saturday schools, language retention, and the secular organizations maintained by Vancouver's German population, it becomes apparent that Germans' attempt to adjust to Canadian circumstances entailed two, seemingly contradictory phenomena: speedy integration and assimilation into the mainstream of Canadian society on one hand, and support for ethnic social, economic, religious, educational, and cultural institutions on the other. The study concludes that assimilation and ethnicity were thus not mutually exclusive. Immigration gave individuals the opportunity to weigh alternatives with regard to social form and institutions, personal values, and the role of their ethnicity in the new life offered by Canada. Consequently, involvement in the local German community may be attributed to as complex causes as the supersession of ethnic origin as a basis of association by other sources of group identification. Yet, even though German-Canadians were highly assimilated into Canadian society by the end of the postwar period, they may have preserved a sense of ethnic identity that did not manifest itself in any visible behaviour.

A reinforcing rod corrosion critical chloride amount measuring method comprises steps of: injecting acidity solution in a precipitate consisting of concrete piece and distilled water by single step; converting concentration of the injected acid when pH of the precipitate reduces to 10.0 to concentration of hydrogen ion; calculating a rate of [H+] of the injected acid with [Cl-] of precipitate; and determining the reinforcing rod corrosion critical chloride amount by a rate of [H+].


An electroactive polymer is a material capable of changing its size and shape when an electric field is present. It is composed of a thin film of dielectric elastomer and two electrodes placed on the top and bottom of the dielectric material. Since the rediscovery of their capabilities, electroactive polymers have been proposed as novel materials for use in numerous fields such as in bioengineering, electronics, hydraulics, and aerospace. It has been demonstrated that the actuation potential of electroactive polymer dielastomers can be significantly enhanced by mechanically pre-straining the material prior to application of an electric field. Application of uniform pre-strain is critical for uniform actuation and is challenging to achieve. This research details methods for constructing an automated uniform stretcher that resulted in the production of a LabView controlled iris stretcher for flexible materials. The high torque stretcher was capable of pre-straining materials with a minimum diameter of 1 inch mm) to a maximum diameter of 16 inches. The stretcher calculates the percent strain and has adjustable speed control through a high torque micro-stepper motor and controller. The stretcher's capabilities were demonstrated on materials within varying tensile strengths up to 725 psi.


Primary arterial thrombosis of nonembolic origin has been stated1to be unquestionably of bacterial origin. Only within the past thirty years, however, has much attention been directed toward, or any observation made of, thrombosis associated with infectious fevers. Arterial thrombosis is not considered to be unusual in cases of influenza, but in the other infectious diseases in which it has been encountered it is described as an uncommon complication. Welch2stated that arterial thrombosis associated with gonorrhea is very rare. Heller's3collection of only twenty-six instances from the literature illustrates its infrequency of occurrence. Frazier1stated that chemical changes in the blood resulting in a liberation of fibrin ferment must be considered as an important etiologic factor in the production of arterial thrombosis. Welch stated that this factor is of undoubted importance, especially in thrombosis in toxic conditions. It is entirely conceivable that the intramuscular injection


Measured results of three typical internal mobile phone antennas held in talk-position by a real human operator are presented. Depending on exact placement of index finger, frequency band and type/position of radiator, total body losses ranging from 6-26 dB have been measured. In all cases, the absorption loss was much more significant than the mismatch loss. The monopole (off-ground) antenna was more affected by the head+hand than the PIFA antennas, in particular for the common placement in the bottom of the phone.


Being a social presence, people participate in social life in the public spaces of the city. In these areas, they are in perceptual and physical contact with each other and get the opportunity to socialize. Social life culture contributes to urban culture and urban identity while keeping communities together. Cities creates areas for people to express themselves outside of their basic needs. The art used in the expression of an emotion, design and beauty has been included in our socio-cultural life in public spaces over time. Public art, which provides social, physical, environmental and economic contributions to the society and the city, is a manifestation of a multi-layered and multi-dimensional expression that includes different representations. Public art representations are important urban images and are the sensory components of collective memory. Today, in the process where the cities start to look alike, public art representations identified with the place make sense of the space and contribute to the identity of the city. In our study, the approach of landscape architecture to this subject will be evaluated by making important public art representations and city readings. Keyword: Public Spaces; Public Art; Landscape Architecture; Identity; Social Life. 1 . Introduction Being a social presence, people participate in social life in the public spaces of the city. These areas, which contain daily life, provide opportunities for a series of actions and activities that improve people's quality of life. Public spaces are areas where people, regardless of age, gender, and nationality, can be used without any discrimination according to the principle of equality. These spaces are areas that offer social wealth with different groups coming together at different times. At the same time, they are cultural venues where individual and social value stand out and symbolize culture. Public spaces, which are very important for both cities and individuals, are the known and recognized face of the cities. Therefore, public spaces are the areas where social participation is intensely observed. It is a kind of meeting place. These areas are prestigious places where people sometimes want to be alone and sometimes meet with other people. Public spaces, as a venue for artistic, religious, social, political and political actions, are common meeting areas, an important part of urban culture and democratic spaces of the city. In other words, they are interaction areas that direct social life and display public activities. Public spaces differ from society to society, from culture to cultures and reflect the unique identity of each society. In summary, these areas are the places of discourse, action, consensus and representation of our cities. 2 . Public Space and Public Art The concept of "public space"; It was first described by Jürgen Habermas, one of the important thinkers, as the spaces and spaces existing in social life (Uysal, 2019). Public spaces are an integral part of the culture of cities that generally shaping a city's image and identity (Reitan, 2014). These spaces range in form from informal street corners to grand civic set pieces. At a larger scale, formal public spaces have long had an important role as the perceived centres of settlements of all types and as the focus for public life, activities and events. At a smaller scale, they might simply be somewhere to rest, hang out, or play whilst providing a visual pause in the flow of streets through urban areas (Carmona, 2018). Therefore, the importance of public spaces is hidden both in their integrity and in their relationships with their environment and in the parts inside them (Ercan, 2013). In addition, space includes not only physical actions such as accommodation, but also psychological, social and thought-based actions, and forms of expression that encompass art and design (Uluçay, 2019). Public art is an art work that can be temporary or permanent in the field, exhibited in public spaces. The installation of the art work is designed to convey an important message for the society; it can tell the story or 3 International Conference of Contemporary Affairs in Architecture and Urbanism (ICCAUA-2020) 6-8 May 2020 ICCAUA2020 Conference Proceedings, AHEP University, Alanya, Turkey 370 connect the history and culture of a particular place (Motoyama & Hanyu, 2014; Zebracki et al, 2010; Hall & Robertson, 2001). Public space is the concept used in modern social theories to refer to the common social activity area in which thoughts, discourses and actions to identify and realize the common good of society are produced and developed (URL 1). According to Habermas, public space is an area where individuals who come together can gather about public interest issues and talk in an unrestricted manner by conducting public reasoning. And individuals here have the opportunity for a social consensus where they can take advantage of the richness of their contrasts and actively use social participation networks. Thus, they can push the system back and act as a public body (Hekimoğlu, 2018). Public art, on the other hand, is sometimes a piece that defines public space, sometimes it can be any artistic element or activity exhibited in public space, and sometimes it is the whole of public space (Ercan, 2013; Worth, 2003). The areas where the works are exhibited can be places such as roads, streets, parks, squares, building facades and green spaces. Public art appeared in some European and North American cities in the 1960s (Finkelpearl, 2001; Miles, 1997). This art first refers to artworks, put into public places such as city squares, government buildings, plazas, hospitals and railway stations (Motoyama & Hanyu, 2014). The 1980s saw the emergence of public art as a profession in the service of urban development. A hybrid form at the intersection of sculpture, painting, photography and architecture which had, paradoxically, little to do with actual artistic pursuits and more in common with urban amenities or development policies (Mitrache, 2012). Recently, the installation of this art in new projects and urban redevelopment/gentrification projects has rapidly become popular as in Japan as well as many countries (Motoyama & Hanyu, 2014). Public art is a domain of contested terminology; public art can be read in different ways and its uses to beautify the city or celebrate its reimagineering do not necessarily enjoy universal consensus (Zebracki et al, 2010). Public art is an oxymoron according to the standards of modernist art and aesthetic theory (Hein, 1996). And also public art today seems to engage more abstract concerns and more ephemeral interpretations of site, memory, and meaning. Space and time continue to play a definitive part, but like most philosophical categories, their meaning has grown attenuated. They no longer refer simply to "where" and "when," but have become symbolic and relational indicators, far removed from the coordinates that once sufficed to situate things (Hein, 1996). According to Chang (2008), public art is an artistic expression of artist and community that can found in a variety of forms, materials and processes, either permanently or temporarily installed in public space. It includes freestanding sculptures, monuments, archway and artist-designed street furniture and artwork integrated with building such as murals, architectural details and digital display (Jasmi&Mohamad, 2016). In summary, public art has become meaningful in many disciplines such as architecture, fine arts, urban scientists, landscape architecture with its versatile structure and has become an effective means of social communication. With this research, the usage forms of public art in landscape architecture will be interpreted with important public art representations. 3 . Public Art Representations in Landscape Architecture In landscape architecture, which is competent in planning, designing, protecting and developing open spaces, public art and its representations have an important place. Art is the transformation of a culture or a concept with different art works depending on the artist's original interpretation. These works can appear in many different environments and can be exhibited. Public art works are also diverse in form and function. According to the European Landscape Convention, everything that falls into the field of view of people is part of the landscape. Therefore, while the works of art in different environments both at the building level and open spaces increase the value of the landscape, they also contribute to the meeting of people with art. The art works exhibited in modern art museums and galleries effectively reshaped public spaces as they went beyond "time" and "space". Two different contemporary design approaches were seen in public spaces linked to museums and galleries: First, it can be defended from a series of social interactions that are linked to the museum and gallery experience (introspective, reverent, respectful, receptive, etc ..) and are therefore permitted in public spaces; Secondly, public spaces that are not connected to museums or galleries but decorated with the presence of works of art (Mitrache, 2012). People watch the art works exhibited in museums in a determined route. As there is no pre-planned route in public spaces, there is a spontaneous experience developing spontaneously. These spaces require something in their physical form that allows us to distinguish them from their environments as a clear and identifiable place (Carmona, 2018). For example, the value it adds to space and the city, its historical, aesthetic and functional value. In this context, museums have become permanent public art representation spaces where culture and art intersect with the social, artistic and educational activities, as well as temporary exhibitions, which are constantly renewed with their close surroundings, from the location of the buildings wh


The surface morphology of vicinal (100) single‐crystal diamond surfaces homoepitaxially grown in a microwave plasma‐assisted chemical vapor deposition (MPACVD) reactor is studied. High‐pressure and high‐temperature (HPHT) single‐crystal diamond substrates produced by different vendors are used as substrates. Prior to the CVD growth, substrates were mechanically polished and etched in a separate inductively coupled plasma/reactive ion etching (ICP/RIE) tool using an Ar/Cl2 gas mixture. The impact of (a) ICP etching regime of the HPHT substrate, (b) substrate polishing, and (c) the HPHT substrate misorientation (off‐axis) vicinal angle on the surface morphology is examined. It was found that the ICP etching removes polishing‐induced defects in the bulk and also removes diamond particles which are left on the surface of single‐crystalline diamond after polishing. The morphology of the surface of the homoepitaxial CVD diamond grown on a substrate, which is free of polishing defects, depends not only on the parameters of the growth process (substrate temperature, composition of the gas mixture, pressure, etc.), but also on the value and direction of the off‐axis angle.


A soft elastohydrodynamic lubrication model for a conformal one-dimensional sliding contact is presented. We describe surface-surface and fluid-surface interactions in conditions where asperities are in direct contact (mixed lubrication), and the effective film thickness is comparable in size to the roughness of the bounding surfaces. In the conditions considered, surfaces have a low elastic modulus, and fluid pressures have a low magnitude, relative to those found in most tribology applications. An interesting coupling is exhibited between the surface roughness, the global elasticity, and the fluid pressure. As opposed to typical tribological applications in conformal mixed lubrication contact, fluid pressure is strong enough to cause significant elastic displacement of the mean boundary surfaces. The deformation is taken into account in an iterative process to compute the resulting spatially dependent stresses, deformations and fluid pressures.

PURPOSE
To present the first gonadotropinoma presenting as pseudo-menopause in a teenager.

METHODS
Human menopausal gonadotropins (hMG) were given to a 37-year-old woman whose hypergonadotropic amenorrhea with estrogen deficiency as a teenager was changed to hypogonadotropic amenorrhea by the growth and prolactin secretion of a macroprolactinoma.

RESULTS
The patient responded multiple times, and every time to stimulation with hMG and each time produced several dominant follicles. She delivered two babies including conception at age 40.

CONCLUSIONS
The fact that this woman could respond consistently to hMG 20 years after the diagnosis of premature menopause, it is clear that initially the etiology of the extremely high LH and FSH levels in an estrogen-deficient 18-year-old was the presence of gonadotropinoma secreting inert LH and FSH. Since serum prolactin was measured the first time at age 37, it is not clear whether the endogenous biologically active gonadotropine were suppressed by replacement of the gonadotroph cells with tumor cells or suppression of endogenous gonadotropins by hyperprolactinoma.


This work originates from the observation of the frequency distribution of the Irish system as obtained from a Frequency Disturbance Recorder lent to the last author by the University of Tennessee. The probability density function of such a distribution appears to be bimodal. The paper first investigates how stochastic sources, in particular, load and wind power estimation errors, impact on the distribution of the frequency of a high-voltage transmission system. Then, possible routes to obtain a bimodal distribution of the frequency are explored and the most likely cause that leads to the observed behaviour of the Irish system is identified. Finally, the paper presents a comparison of different frequency regulation strategies and their impact on the distribution of the frequency. A sensitivity analysis of wind speed and load parameters is presented and discussed based on the IEEE-14 bus system.


The dynamics of participation in government programs can be studied using longitudinal data from the Survey of Income and Program Participation (SIPP). This paper examines some of the issues involved in such analysis, focusing first on the kinds of analysis that SIPP data allow. The second section discusses the major problems with the SIPP that complicate longitudinal analyses. A concluding section suggests changes that could simplify and improve the data.


The overall objective of this study was to analyze the sporting attractions of Razavi Khorasan using the combined SWOT and AHP.The population of professionals, managers and academics in the exercise of which about 20 persons were selected for this purpose.In the present study, experts, managers and academics were asked to state the importance of exercise, internal factors (strengths and weaknesses) and external factors (opportunities and threats) to identify the attractions of sport that ranged from 64 (30 variables of weakness ، 13 variables of strengths ، 11 variables of opportunities and 10 variables of threats) identified 28 relevant variables (7 variables of weakness ، 7 variables of strengths ، 7 variables of opportunities and 7 variables of threats) were included in the final questionnaire.

As the next-generation display technology, microscale light-emitting diode (μ-LED) displays have attracted significant attention recently. For applying μ-LEDs as direct emissive pixels in everyday display applications, many chips in a relatively small-sized wafer must be relocated and distributed quickly over a wide screen area via so-called transfer technology. After a brief review of current conventional transfer technologies for placing μ-LEDs on a wide screen, for perspective, a new and versatile delivery technique for μ-LEDs is presented, in which an LED chip is converted to a ball shape in order to facilitate handling and processing of μ-LEDs for practical applications. Plausible procedures including the formation, arrangement, and removal of the plastic ball are discussed to envision potential impacts of the technology.


T HE SEA and the islands and continents that lie beyond have determined Portuguese history strikingly more than the national territory on the Iberian Peninsula. This holds true in matters of the spirit as well as in social, economic or political development. Portuguese literature has, to a large extent, been a literature of travelers, migrants and adventurers, though not, surprisingly, of sailors or fishermen. Seaborne commerce of salt and fish first made Portugal important in the middle ages, giving it allies who sailed to Lisbon to drive out the Moors. Navigators prepared her brief age of glory in the sixteenth century. The sea pulsates through the great literary works of that golden age: the Dicadas da Asia, the Lusiads, and the Peregrination. A series of disasters struck the nation so that a Frenchman, Paul Hazard, could speak of the "tragic history of Portugal," punctuated by the shipwrecks of the Histdria traigico-maritima. Portugal continues to look out to the sea, like the barefoot maiden of Unamuno's poem, moodily gazing into the sun as it is setting on the Atlantic. British seapower saved Portuguese independence from Napoleon; it also played an ambiguous role in the ensuing civil wars, begun in the Azores, after Brazil had shaken herself loose. With their naval guns, the British stopped the Portuguese from building a new empire across the African continent. Great Britain's ultimatum of 1890 so deeply hurt Portuguese pride and pocketbook that it accelerated the desire for national regeneration and led to the fall of the Portuguese monarchy, one of the oldest in Europe. With the establishment of a republic in 1910, the twentieth century began in Portugal.


Purpose: The purpose of this study was to identify whether abnormal near point convergence (NPC) could be used as a clinical predictor of a 10-18 year old student's ability to successfully return to learning (RTL). Methods and Study Design: This was a retrospective chart review of 122 students who initially visited a sports medicine clinic between 11/22/17 to 02/27/19 due to a concussion. A total of 268 visits were analyzed. RTL is graded in color zones, with red = no school, orange = half time or less, yellow = half time or more, green = full time with accommodations, and blue = full clearance. No patients were reported in the red zone in our cohort due to its severity. Patients with learning disabilities or oculomotor deficits were excluded. Results: Of the patients who met the inclusion criteria, we found a statistically significant difference in average NPC between the blue and orange zones (p<0.001) using a pooled proportions test. Average NPC was 7.03cm for blue, 8.84cm for green, 12.67cm for yellow, and 14.40cm for orange representing a positive linear correlation with an R2 of 0.975. Whereas 81% of patients in the blue zone had a normal NPC (<9cm), this was true for only 31% of patients in the orange zone. There was a 43% increase in average NPC from yellow to green zone. Yellow was the most frequent color zone with 56.7% of all visits in this zone. Conclusions: NPC appears to have a strong correlation with academic tolerance and can be predictive of RTL zones. Significance: Currently, little research has been done on clinical predictors of RTL. This data supports the use of oculomotor testing, such as NPC, which can easily be completed at office visits, as predictive tools that may indicate which patients presenting with concussion need increased academic accommodations.

Currently, the methods that use microwaves to promote the growth of carbon nanotubes (CNT) employ waveguides in their configuration. We describe a method for synthesizing CNT based on the use of a microwave plasma at atmospheric pressure, and maintained by a resonant cavity. The replacement of waveguides by the resonant cavity results in deposition areas greater than 15 cm2, and is therefore not limited by the equipment configuration, since plasma is formed in almost the entire length of the quartz tube. As a result, confirmed by Raman spectroscopy and scanning and transmission electron microscopy, good quality carbon nanotubes were obtained, with an ID/IG ratio less than one unit in addition to the possibility of tuning the nanostructure diameter through process conditions.

This paper presents some of the more relevant conclusions of our research into student attitudes towards the university as an indicator of university quality. The paper studies the genesis of student attitudes towards the university as a fundamental referent of potential student behaviour in the university context. The purpose of the research is mainly to evaluate the formative role of the university in promoting attitudes. This role is also considered a university quality indicator. Five hundred and fifty-four students were asked to answer a demanding questionnaire of 327 items about 55 different university dimensions. The questionnaire is therefore felt to present a complete X-ray picture of the university institution as a formation context. The dimensions were grouped into 14 ranges for analysis. The foremost ranges were: the university and its prestige, university rules, the syllabus, student participation, the teaching/learning process, lecturers and non-institutional university life. It was found that students take in quite a lot of information, but this information varies greatly depending on the university dimensions studied. Furthermore, the information is not very cohesive on account of the heterogeneity of its sources, and it is only superficially assumed by students. In addition, there are important differences amongst the different areas of knowledge. The situation as a whole contributes to the perpetuation of the role of the student as a «pupil», as opposed to an autonomous, active member of the university community.

LHI proposed the simple and safe reinforcement method of PHC pile(D=450mm) at 2009. And then, capability tests were carried out to insure the proposed method. Tests results showed that reinforcement amount of the proposed method could be reduced. So, LHI started the research to determine the optinum reinforcement amount of PHC pile(D=450, 500, 600㎜). Also, LHI carried out capability tests. This paper presents some content of the research.


k g The paper ''The Hurst exponent and long-time corre tion'' by G. Wang et al. reaches a very surprising conclu sion. The authors state: ''It @ he fact thatH is well above 0.5# is found to be connected with short-time correlations These results suggest that the R/S method is not appropriate for evaluating long-time correlations in fusion devices This conclusion is surprising in several respects. First, R/S method has been applied with success in many fields a tool for investigating long-range dependencies. The r tionship between a high value of the Hurst parameter, H, and self-affinity ~i.e., long-term memory or long-range depe dency! has been established in a large number publications. 3 It is difficult to understand how and why th method should lead to different conclusions in the particu case of probe data from Tore Supra. Second, their conclu does not answer the question of why and how short-ra correlations should appear as long-range dependencies nally, the statement that this failure is generic to fusion vices is also surprising. The test of theR/S method suggested by the authors reasonable. It is an extension of the standard test of shuffling, which we ourselves have used in testing our R/S algorithm. The test consists of subdividing the data set in blocks of lengthN and shuffling the blocks. This shoul decorrelate any scales longer than N. One must, however, be careful when choosing a range of time lags over which th H exponent is determined. There is no discussion of this p in the paper, nor do the authors give any details about ranges they have used. The range should be such tha R/S trace has a well-defined power scaling, it should inclu at least a decade of lag values, and its lower end should b lags that are large compared to the size of the blocks N. Also, one should bear in mind that the high range of values of R/S has poor statistics~is calculated from few independent es mates!, so that the accuracy of the R/S values decreases wit increasing time lag. It is difficult to give a more detaile numerical prescription for the calculation of H. One should


1. Introduction. Imagine a collection of books labeled 1 through n arranged in a row in some order. We reorganize the row of books by successively choosing a book at random: choosing book i with probability w i and moving it to the front of the row. This " move-to-front rule " determines an interesting Markov chain on the set of arrangements of the books. If σ and τ denote any two orderings of the books, then the probability of transition from σ to τ is w i if and only if τ is obtained from σ by moving book i to the front. This Markov chain is commonly called the Tsetlin library or move-to-front scheme. Due to its use in computer science as a standard scheme for dynamic file maintenance as well as cache maintenance (cf. [Do], [FHo], and [P]), the move-to-front rule is a very well-studied Markov chain. A primary resource for this problem is Fill's comprehensive paper [F], which derives the transition probabilities for any number of steps of the chain and the eigenvalues with corresponding idempotents and discusses the rate of convergence to stationarity. Its thorough bibliography contains a wealth of pointers to the relevant literature. Of particular interest is the spectrum of this Markov chain. In general, knowledge of the eigenvalues for the transition matrix of a Markov chain can give some indication of the rate at which the chain converges to its equilibrium distribution. In the case of the Tsetlin library, the eigenvalues have an elegant formula, discovered (independently) Theorem 1.1. The distinct eigenvalues for the move-to-front rule are indexed by subsets A ⊆ {1,. .. , n} and given by λ A = i∈A w i. The multiplicity of λ A is the number of derangements (permutations with no fixed points) of the set {1,. .. , n − |A|} In this paper we study a sequence of generalizations of the Tsetlin library, culminating in a generalization of the setting of central hyperplane arrangements. In each case we develop a formula analogous to Theorem 1.1 for the distinct eigenvalues and multiplicities for this more general class of Markov chains. Our first generalization comes from viewing move-to-front as the operation of moving the books in the subset {i} to the front and then moving the subset [n] − {i} behind {i} while retaining their relative order; this is all done with probability w i …


Magnesium titanate MgTiO3 with ilmenite structure is a good microwave ceramic material because of its dielectric properties (high Q values and low dielectric constant). So it has been widely applied in many fields. The main preparations of nanometer magnesium titanate including precipitation method, sol-gel method and mechanochemical method, etc, were summarized,and the developing features and shortages for every method were analyzed. In the end, the development trend of nanometer MgTiO3 was pointed out.


This chapter describes how Clarke's science fiction consistently advocates, and vividly depicts, humanity's future achievements in space. Without providing a consistent "Future History," his stories collectively argue that humans will gradually colonize space stations, the moon, Mars, and other planets and moons, though humans may never advance beyond the solar system. Clarke unusually acknowledges the need for computers in space, and instead of featuring pioneering expeditions, he usually focuses on the everyday lives of space colonists, emphasizing both the perils of space life and its potential benefits, such as greater longevity. Living aliens are rarely encountered, though evidence of ancient aliens may be detected. Clarke's major novel about human space travel, Imperial Earth (1975), explores life on Titan by chronicling a resident's visit to Earth.


The current pace of innovation in computing makes it difficult to assume a fixed set of requirements for the whole life span of a system. Aggressive technology scaling also imposes additional constraints to modern hardware platforms. Field-Programmable Gate Array (FPGA) reconfiguration can help systems cope with dynamic requirements such as performance and power, hardware defects due to Negative-Bias Temperature Instability (NBTI) and Process, Voltage and Temperature (PVT) variations, or application requirements unforeseen at design time. This work proposes a framework for reconfigurable components whereby the reconfiguration of a component implementation is performed transparently without user intervention. The reconfiguration process is confined in system's idle time without interfering with or being interfered by other activities occurring in the system or even peripherals performing I/O. A telecommunications switch was used as a case study for the deployment of reconfigurable components as well as the impact I/O interference has in the process and to explore non-functional trade-offs between implementations.


This inception workshop was the first activity of the research project 'Decentralised Market Information Service in Lira District, Uganda', which is funded by the DFID Crop Post-Harvest Research Programme. The main objective of this project is to test information delivery models for poor farming communities, with emphasis on decentralised market information services and the use of FM Radio.


Ice cores and glacial records reveal that European glaciers retreated before the rise of industrialization in the 1870s, suggesting that soot deposition did not primarily drive the shift.


BACKGROUND
Injection of the centrodistal (CD) joint in the horse is a commonly performed procedure for both diagnostic and therapeutic purposes. This procedure can be technically challenging, and while radiographic guidance has been previously used, ultrasound localised injection of the CD joint has not been described.

OBJECTIVES
The purpose of this study was to explore the feasibility of using ultrasound localisation to increase the accuracy of CD joint injection.

STUDY DESIGN
Experimental method assessment.

METHODS
One operator performed the ultrasound and injection of 24 CD joints in 12 sedated horses. The joints were injected with iohexol (2 ml), sterile saline (1.5 ml), and amikacin (0.5 ml). Dorsoplantar and dorsomedial plantarolateral radiographic projections were obtained immediately after injection to evaluate the presence of contrast material in the CD joint.

RESULTS
The CD joint was successfully injected in 17/24 joints, representing a 70.8% accuracy.

MAIN LIMITATIONS
The horses used in this study were from the University research herd, and not clinical cases. One investigator performed all the ultrasonography and CD joint injections.

CONCLUSIONS
The use of ultrasound localisation could improve success of CD joint injection as well as improve the learning curve of less experienced practitioners learning this procedure.


In this paper, we generalise multiple kernel Fisher discriminant analysis (MK-FDA) such that the kernel weights can be regularised with an ℓp norm for any p ≥ 1, in contrast to existing MK-FDA that uses either l1 or l2 norm. We present formulations for both binary and multiclass cases and solve the associated optimisation problems efficiently with semi-infinite programming. We show on three object and image categorisation benchmarks that by learning the intrinsic sparsity of a given set of base kernels using a validation set, the proposed ℓp MK-FDA outperforms its fixed-norm counterparts, and is capable of producing state-of-the-art performance. Moreover, we show that our ℓp MK-FDA outperforms the ℓp multiple kernel support vector machine (ℓp MK-SVM) which has been recently proposed. Based on this observation and our experience with single kernel FDA and SVM, we argue that the almost century-old FDA is still a strong competitor of the popular SVM.


A number of 8-dipropylamino-7,8,9,10-tetrahydrophenanthridines have been prepared as analogs of the known serotoninergic agonist 8-hydroxy-2-(dipropylamino)tetralin (8-OH-DPAT) and their affinity for the 5-HT 1A receptor subtype evaluated by radioligand binding assay


This article offers a bibliometric overview of the practice guidelines on physiotherapy indexed in the PEDro database between 2003 and 2017. 410 records correspond to guidelines of clinical practice, representing 1% of all production indexed in PEDro. Cardiothoracic and musculoskeletal disorders received most attention from researchers. Pain was the most researched problem and fitness training and education the most researched therapies. The interdisciplinary practices in the various subdisciplines were reflected in the differing degrees of authorship collaboration. Most of the research was carried out in universities located in the USA, the United Kingdom, Australia and Canada. The research outputs were scattered in many journals with a core of ten journals including some from the general medical and health sciences. This study provides an overview of the productivity and visibility of research work in clinical practice guidelines in physiotherapy. The results could be used to organize and prioritize future research efforts in research in the field.

In this study, we compare realized measure and implied volatility for forecasting of the volatility. Firstly, we employ a family of homogenous loss functions as the evaluation criteria in order to run a fair and complete forecast comparison. Our results show that, predictors based on realized measures are superior to that derived from implied volatility for both within-sample fitting and one-step-ahead forecasting, whereas the superiority of the latter type is presented in multi-step-ahead forecasting. Secondly, as a result of the comparison, a new model average approach with weights that depend on market conditions is developed to combine the information from implied volatility and realized measure for volatility forecasting. And our results show the superiority of the proposed approach in combining realized measures and implied volatility for volatility prediction.


For an arbitrary del Pezzo surface S, we compute alpha(S), which is the volume of a certain polytope in the dual of the effective cone of S, using Magma and Polymake. The constant alpha(S) appears in Peyre's conjecture for the leading term in the asymptotic formula for the number of rational points of bounded height on S over number fields.


Karyotype and DNA analyses using DNA probes were carried out in a family with the Cohen syndrome. Two affected brothers had normal chromosomal constitutions. A major deletion or duplication of genomic DNA fragments hybridized with the DNA probes, pML34 at D15S9 locus and pTD3‐21 at D15S10 locus, assigned on 15q11‐q12 was not detected in the patients. In addition, a linkage of the syndrome to D15S9 and D15S10 loci was not observed in the family. These data suggest that a gene for the Cohen syndrome is excluded from the 15q11‐q12 region, on which a gene for the Prader‐Willi syndrome is assigned, and that the Cohen syndrome is distinctly different from the Prader‐Willi syndrome, although clinical manifestations of the Cohen and the Prader‐Willi syndromes are very similar.


A weighted multi-criteria model is built to maximize the distribution of students into academic programs of a department. The optimal distribution of students to these programs is determined by taking into account the constraints inherent in each academic program while complying with the limits of space capacity, the constraints of financial allocation, the number of instructors and affirmative action quotas. Each constraint has a weight attached to it that must be met. This model is applied to the School of Mathematical Sciences, Universiti Kebangsaan Malaysia, which consists of three academic programs. The successful application demonstrates the ability of the model to provide optimal distribution in compliance with the student intake requirement and constraints of each academic program in the department.


To reduce the expected harm its product causes to consumers, a firm can invest in a product's safety before sale or mitigate harm after sale in the event product risks materialize. After-sale harm mitigation interferes with consumers' product use and reduces consumption benefits. We describe a firm's incentives for safety investments and harm mitigation as a function of the level of the firm's liability. Whereas post-sale mitigation incentives are scaled up by liability, pre-sale product safety is a U-shaped function of liability, making the two harm reduction instruments substitutes at low levels of liability and complements at high levels. To induce efficient harm mitigation, liability must be less than full. Further reducing the level of liability improves product safety at the cost of the firm's profits. (JEL K13, D42).


ABSTRACT The accuracy of imaging for bulk volume estimation of apple slices in the process of drying at temperatures from 40 to 80°C was investigated and compared with physical caliper measurements. The initial hypothesis was to estimate bulk volume of cylindrically shaped apple slices from diameter and thickness imaging. Imaging of diameter showed strong agreement with caliper measurements throughout the entire drying process, however imaging of thickness was not accurate due to the irregular shrinkage and bending phenomena. A linear model reflecting the relationship between diameter and bulk volume was developed and validated at temperatures of 40, 60, and 80°C. It showed good correlation between imaging diameter and bulk volume changes in the range of moisture contents from 9.1 to 0.25 g/g. The relative percentage error of the prediction model was approximately 6.45%, which suggests that imaging can be used as a robust tool for bulk volume estimation of apple slices during convective drying.


The objective of this article was to validate the Spanish version of a prosociality scale that evaluates prosociality toward family members, friends, and strangers. This objective was developed in two studies. In Study 1, exploratory factor analysis was conducted to test the construct validity of the scale. The reliability was tested using McDonald's omega coefficient and coefficient H. In Study 2, confirmatory factor analysis was conducted to confirm the structure of the scale. Moreover, the convergent validity of the Prosocial Behavior Scale toward Different Targets was studied by analyzing its correlation with other well-known scales: the Prosocial Tendencies Measure and Interpersonal Reactivity Index.


This paper reports surface acoustic wave (SAW) devices fabricated on AlN epitaxial film grown on sapphire, aiming to avoid the detrimental polarization axis inconsistency and refrained crystalline quality of the normally used polycrystalline AlN films. Devices with center frequency of 357 MHz and 714 MHz have been fabricated. The stop band rejection ratio of the as-obtained device reaches 24.5 dB and the pass band ripple is profoundly smaller compared to most of the reported AlN SAW devices with the similar configuration. Judging from the rather high edge dislocation level of the film used in this study, the properties of the SAW devices have great potential to be improved by further improving the crystalline quality of the film. It is then concluded that the AlN epitaxial film is favorable for high quality SAW devices to meet the high frequency and low power consumption challenges facing the signal processing components.


Objective:To explore the mechanism of chinese drugs Fugongning on cures of Endometriosis at the molecular level, and to investigate whether apoptosis is induced in endometriosis by the medicine. Methods: After making EMT animal model the rats were treated with Fugongning. Danazol and both medicines. Then apoptotic cells were detected by flow cytometry (FCM).Result:1. On gross examination the size of transplant in treated groups was significantly decresed as compared with that of control ( P 0 05). The growth of Endometriotic cells were inhibited. 2.The apoptosis index in Fugongning, Danazol and the both medicine group was significantly higher than that of control ( P 0 )1).3.After treatment with Fugongning, Danazol and both medicines, there were apoptotic peaks in cell cycle analysis on FCM. The cells in S phase were obvionsly increased ( P 0 01),which indicated that cell cycles were hindered in S phase. 4. The serum E 2 level in Fugongning, Danazol and the both medicine group was significantly lower that that of control ( P 0 05). Conclusion: This study indicates that Fugongning can induce apoptosis of Endometriotic cells. The possible mechanism is from decreasing the serum E 2 level to suppress bc1 2 expression in endometriotic cells.


Since there is 87% of chance of an approximately 8.0-magnitude earthquake occurring in the Tokai region of Japan within the next 30 years; we are trying to help computers to recommend suitable action patterns for the victims if this massive earthquake happens. For example, the computer will recommend " what should do to go to a safe place ", " how to come back home ", etc. To realize this goal, it is necessary to have collective intelligence of action patterns, which relate to the earthquake . It is also important to let the computers make a recommendationin time, especially in this kind of emergency situation. This means these action patterns should to be collected in real-time. Additionally, to help the computers understand the meaning of these action patterns, we should build the collective intelligence based on web ontology language (OWL). However, the manual construction of the collective intelligence will take a large cost, and it is difficult in the emergency situation. Therefore, in this paper, we first design a time series action network. We then introduce a novel approach, which can automatically collects the action patterns from Twitter for the action network in realtime. Finally, we propose a novel action-based collaborative filtering, which predicts missing activity data, to complement this action network.


Due to the precautionary measures during the COVID-19 pandemic many universities offered unproctored take-home exams. We propose methods to detect potential collusion between students and apply our approach on event log data from take-home exams during the pandemic. We find groups of students with suspiciously similar exams. In addition, we compare our findings to a proctored control group. By this, we establish a rule of thumb for evaluating which cases are "outstandingly similar", i.e., suspicious cases.


As this special double issue goes to press, we pause to note with sadness the passing of Thomas C. Schelling, among the most distinctive figures in public-policy research in postwar America. His published work ranged over half a dozen areas, including the problems of drug addiction, residential segregation, and climate change, but his deepest contributions dealt with the enduring challenges of living in aworld with nuclear weapons. Two areas stand out. Strategy andArms Control, coauthored with Morton H. Halperin in 1961, continues to embody the idea of arms control as a form of "responsible military policy"—that is, a means of national survival. Schelling's work on the strategy of deterrence is the foundation stone; could it be lifted, it would rest in the balance against all else. I was privileged to study with Professor Schelling at the University of Maryland College Park in the late 1990s. When we met again in recent years, he remained as thoughtful, gentle, and self-possessed as ever. His memory is an unalloyed blessing. The first half of this special double issue is devoted to the Comprehensive Nuclear-Test-Ban Treaty (CTBT), the "longest sought, hardest fought" achievement of arms control, in President Bill Clinton's words, and the most elusive. Nearly two decades ago, the ratification of the CTBT in the US Senate fell victim to the same political polarization that now threatens to bring the republic to its lowest point since the presidency of Richard M. Nixon, if not since the nineteenth century. The treaty's lingering, indeterminate status bulks large among the frustrations that tear at the global nonproliferation consensus. Yet even without entry into force, the CTBT has been institutionalized in the Preparatory Commission for the Comprehensive NuclearTest-Ban Treaty Organization (CTBTO), which already provides unique services to the cause of controlling nuclear dangers. Should any state test a nuclear device, other nations and publics need not accept the word of any particular government about the event; the CTBTO's International Monitoring System (IMS) is highly effective and broadly credible. The extent of participation in the detection network places it among the world's broadest international scientific collaborations. If anything, we may undervalue the CTBT. Thomas Schelling's perspective on the matter is worth recalling here. The treaty's greatest contribution, he once suggested, dwells in the opportunity to reinforce the tradition of non-use of nuclear weapons since 1945: "The symbolic effect of 180 or more nations ratifying the CTBT, which is nominally only about testing, should add enormously to the convention that nuclear weapons are not to be used and that any nation that does use nuclear weapons will be judged the violator of the legacy of Hiroshima." Reflecting on this observation, we may dare to hope that the chief weakness of the treaty—its onerous requirements for entry into force—will yet emerge as a source of power. The editorial staff of the NPR extends its gratitude to Laura Rockwood, director of the Vienna Center for Disarmament and Non-Proliferation (VCDNP), who was primarily responsible for organizing this issue's special section on the CTBT, and to Massimiliano Moretti of the VCDNP, who served as associate editor for this section. An overview of this issue's special section on the CTBT appears in the separate introduction by Laura Rockwood. The editorial staff also extends its gratitude to guest editor Andrew Futter of the University of Leicester, who oversaw the preparation of the latter half of this issue. The articles and view-


Although real estate is believed to be the steady element of a portfolio, volatilities during the global financial crisis has thrown off its "defensive stock" status in terms of optimizing portfolio benefit. Evidence from past research have revealed the same for the Real Estate Investment Trust (REIT) in Malaysia. This paper examines the volatility and stability of the REITs in Malaysia (MREITs), particularly analyzing the correlations between the islamic REITs and their conventional counterparts. We further observe the existence of contagion effects between these assets to ascertain whether the islamic REITs are led by the more established conventional REITs. The DCC-MGARCH model is applied to study the volatilities and correlations within this asset class. We also use the wavelet coherence methodology to see the contagion effects between the REITs, within a time frequency domain. Our contribution to the scarce literature on Islamic REITs is the analysis of time varying correlations from a sector-related perspective, and explaining interdependencies in the time domain as well as the frequency domain. Our findings show that the Malaysian REITs have a long run fundamental relationship with each other, but are independently moving within their respective sectors in the shorter term. The results imply that diversification benefits are not hindered as long as the MREITs held in the portfolio belong to different sectors. Most importantly, although the Shariah (Islamic law) investor may be limited in the selection of investment assets, investing in all three islamic MREITs concurrently will not increase the riskiness of the portfolio.


The law of propagation of uncertainty is first reviewed using matrix notation. This notation is appropriate because the uncertainty in a complex-valued quantity can be expressed as a matrix. This approach is then applied to propagate uncertainty from complex-valued S-parameters to other quantities that occur elsewhere in other microwave measurement applications. The procedure is consistent with the ISO Guide to the expression of uncertainty in measurement [1].

This study assesses the effects of prolonged exposure of fingers to water on the performance of existing fingerprint recognition systems. The dataset used in this research is collected using a high-end, multispectral fingerprint scanner. To perform a data acquisition, we recruited volunteers to contribute their fingerprint samples to the dataset in multiple sessions. Once the dataset is filled with both fingerprints under normal and wrinkled conditions, we use a minutiae-based fingerprint verification system to retrieve the match scores between all combinations of prints. Finally, we use receiver operating characteristic (ROC) curve to measure the behavior of such systems under maritime environment. Using the equal error rate (EER), we successfully quantify the degradation in performance due to water-induced skin pruning, which is approximately 1% reduction in EER.


Demographic change is responsible for the degradation of wetlands Douala. The overall objective of the study is to analyze the impact of uncontrolled human impact on the lives of people and vegetation located in the neighborhoods of Kambo and Longmayagui rivers (Douala). Interviews with heads of district and surveys of the local population have been made. In total 1 314 boxes were counted (125 boxes in Kambo and 1 189 boxes in Longmayagui). Seventy-five people were surveyed in Kambo (60 %) and 450 people in Longmayagui (37.84 %). The local population is mainly originally from western Cameroon. The main reason she moved into these areas is poverty. She practices mainly agriculture on the banks of Longmayagui and Kambo rivers and dump all their waste into rivers. The plants are invasive and regularly cleared it. These plants are useful to local residents for food and traditional medicine. The management of these areas is not a matter for policy makers but each riparian without any help is doing in managing its space. The interviews and surveys have highlighted the complexity of interactions between actors. Respondents are aware: they identify the environmental, social, political and territorial raised by the management of risk areas.

The quest for a chemical signal that can alter human behavior pervades the fragrance industry. Does such a natural human semiochemical (signal- carrying compound) exist? Can we expect to develop such a natural or synthetic chemical attractant? What messages might it carry? Before addressing these intriguing questions, scientists must become intimately familiar with the chemistry and biology of those mammalian odor signals that do, in fact, transmit social and sexual messages. This requires knowledge of possible odor sources,, the mechanism of odor formation, and the complex process of smell, and involves use of the techniques of chemical isolation, identification, and bioassay. Recent books on chemical communication have been written either from the biological perspective (for example, "Pheromones and Reproduction in Mammals") or have been monogaphs from presentations at scientific meetings, such as the series "Chemical Signals in Vertebrates." Now Eric Albone, a chemist affiliated with the University of ...

The article consists of an interview with a
man who has computerised flight simulation
as his hobby. In discussing his hobby, he
stresses the need for a hobby that has no
purpose except the entertainment. From his

Denmark and Europe in real-time. This kind
of flight simulation is, in his own words, "as
real as it gets", and that is just the point. The
virtual aspect presents him with a predicament,
however, since he has a limited amount
of spare time in which to fly, and thus he

Previous work on empirical mode decomposition in two dimensions typically generates a residue with many extrema points. In this paper we propose an improved method to decompose an image into a number of intrinsic mode functions and a residue image with a minimum number of extrema points. We further propose a method for the variable sampling of the two-dimensional empirical mode decomposition. Since traditional frequency concept is not applicable in this work, we introduce the concept of empiquency, shortform for empirical mode frequency, to describe the signal oscillations. The very special properties of the intrinsic mode functions are used for variable sampling in order to reduce the number of parameters to represent the image. This is done blockwise using the occurrence of extrema points of the intrinsic mode function to steer the sampling rate of the block. A method of using overlapping 7 × 7 blocks is introduced to overcome blocking artifacts and to further reduce the number of parameters required to represent the image. The results presented here shows that an image can be successfully decomposed into a number of intrinsic mode functions and a residue image with a minimum number of extrema points. The results also show that subsampling offers a way to keep the total number of samples generated by empirical mode decomposition approximately equal to the number of pixels of the original image.

The present article addresses a current problem in the field of project management, respectively the way in which a project's life cycle can be easier to manage and understand in order to allow for an efficient management process. As the life cycle of a project happens during the time frame in which the project is undertook it is important to start from a strategic development-oriented document, from which the project idea is derived in a certain field (e.g. human resources, infrastructure, environment, tourism etc.). Following this process, the project idea is formulated, implemented and, finally, monitored and evaluated with the purpose of creating the necessary conditions for future development measures. This article presents a series of aspects that were concluded from the analysis of already implemented EU-financed projects. The analysis focused on the importance of the correlation existing between the project and the organizational strategy and, also, the way in which monitoring and evaluation activities concur in improving the implementation process.


Abstract The study of deep-drawing dual-phase steel for usage in car outer panels was researched in a laboratory setting. SEM, XRD and tensile tests were used to characterise the microstructures, mechanical properties and to determine the texture. The results indicated that the texture of dual-phase steel during hot rolling, cold rolling and annealing is inherited. The texture of cold-rolled sheet mainly consists of relatively strong α-fibre texture and weak γ-fibre texture, and the {223}<110> orientation is identified as the stable orientation. Annealing at 860°C strengthens the γ-fibre texture and weakens the α-fibre texture. The gap of the density in {111}<110> orientation and {111}<112> orientation in the γ-fibre texture is small in dual-phase steel, which improves the earing behaviour in deep drawing. The tensile strength, elongation and plastic strain ratio (r value) of the dual-phase steel were 440 MPa, more than 35%, and 1·4, respectively, which met the requirement of high-strength interstitial-free steel, and moreover, the texture was similar to that of interstitial-free steel.


: Introduction: The new coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) , which causes Coronavirus Disease-2019 (COVID-19), was discovered in Wuhan, China in December 2019. The World Health Organization declared a pandemic in March 2020. Different laboratories developed protocols, using reverse transcription technology followed by real-time polymerase chain reaction (RT-PCR) from the nasopharynx and oropharynx swab. Objective: This chapter aims to present the results of the analyzes carried out for the diagnosis of COVID-19 at CLR Santo André, as well as to report the methodological adjustments in the conduct of the laboratory routine. Methodology: A descriptive study of the results of the diagnostic tests for COVID-19 carried out at the CLR Santo André, from April 2020 to February 2021, was carried out, using data compiled from the Laboratory Environment Manager (GAL) system. During the study period, 3 different RT-PCR reaction protocols were used to detect SARS-CoV-2. Results: 60.885 samples of patients suspected of COVID-19 were received. Of the total samples received, 33,56% were positive for SARS-CoV-2, 0,14% showed inconclusive results and 66,30% were negative. On average, 6,670


The swept volumes of moving objects are encountered extensively in solid modeling, robot manipulator workspace, manufacturing automation, mechanical space layout, and other areas, the study of swept volumes is an important basic theory for these areas. In the paper the calculating of swept volume is divided into two phases: the phase of determining of candidate boundaries of the swept volume and the phase of the trimming of candidate boundaries. The study has shown that the two-phase strategy is capable of calculating the swept volume which is applicable to mechanical layout design, therefore providing the basis for determining the workspace in mechanical design, the construction design of parts and the best layout.

In the presence of strong acidity and salicylic acid, the photoreduction process of Cr (VI) ion with different concentrations was in accordance with the zero order kinetic model, The kinetic model of photocatalytic reduction of Cr (VI) on TiO2-WO3 composite catalyst still accords with the zero order reaction of surface catalysis


We discuss the emergence of topological color insulators in optical lattices as quantum phases of SU(3) ultra-cold neutral fermions. We construct the Chern matrix and classify all insulating phases in terms of three topological invariants: the charge-charge, the color-charge and the color-color Chern numbers. Our classification transcends that of SU(2) systems which require only the charge-charge (charge-Hall) and spin-charge (spin-Hall) Chern numbers. To illustrate the topological classification of the insulating phases of SU(3) fermions, we construct phase diagrams of chemical potential and color-orbit parameter versus color-flip fields for fixed magnetic flux ratio.


Cerebral malalria is a life-threatening complication of Plasmodium falciparum infection. RBC exchange transfusion (RCE) can reduce the burden of parasitemia in this situation. We have experienced two cases of cerebral malaria treated with automated RBC exchange as an adjunct to standard chemotherapy. Case 1: A 42year-old male was referred to the emergency room with a history of 3 days of fever after having returned from Congo. Peripheral blood smear showed the P. falciparum parasitemia of 70-80%. Quinidine and doxycycline were administered but, mental state started to deteriorate. He underwent RCE on hospital day 2 to reduce the parasitemia to 10% after 8 hours. No parasite could be found on day 3 after the RCE. Case 2: A 62-year-old male was referred to the emergency room with a history of 3 days of fever after having returned from Cameroon. P. falciparum parasitemia was 10% on peripheral blood smear. Quinidine and doxycycline were immediately started but headache developed abruptly and he underwent RCE on hospital day 3. After 8 hours following the completion of RCE, parasitemia decreased to less than 1%. Automated RBC exchange transfusion can rapidly reduce the burden of parasitemia and achieve improvement of neurologic symptom and sign in patients with cerebral malaria.


In this paper, a neural network approach to forecast Korean regional precipitation is presented. We first analyze the characteristics of the conventional models for time series prediction, and then propose a new model and its learning method for the precipitation forecast. The proposed model is a layered network in which the outputs of a layer are buffered within a given period time and then fed fully connected to the upper layer. This study adopted the dual connections between two layers for the model. The network behavior and learning algorithm for the model are also described. The dual connection structure plays the role of the bias of the ordinary Multi-Layer Perceptron(MLP), and reflects the relationships among the features effectively. From these advantageous features, the model provides the learning efficiency in comparison with the FIR network, which is the most popular model for time series prediction. We have applied the model to the monthly and seasonal forecast of precipitation. The precipitation data and SST(Sea Surface Temperature) data for several decades are used as the learning pattern for the neural network predictor. The experimental results have shown the validity of the proposed model.


With the dawn of e-learning capabilities, the reach of technology in allowing the teaching and tutorial of lessons has never been easier. As such, using intelligent systems to monitor progress in lessons such as guitar lessons make e-learning with guitar playing more interactive. Using images of a person playing a guitar as input, the first step of being able to do this is to be able to discriminate the hand from the rest of the environment. Using a combination of skin tone segmentation and image differencing, the hand blob is obtained. This is then transformed into a 1-d signal and Fourier Descriptors are then extracted using Fourier Transforms. Results show that while some shapes are identified correctly, it is important to make the hand shape stay as 1 blob in order to make it easier for the system to identify the shape.

Vaccination is an important method for the prevention of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) transmission. There is currently a lack of real‐world clinical data regarding the safety and efficacy of coronavirus disease 2019 (COVID‐19) vaccines with respect to plaque psoriasis treatment involving tumor necrosis factor‐α (TNF‐α) and interleukin‐17A (IL‐17A) inhibitors.


Introduction.— Despite the discovery of the 125 GeV boson h at the Large Hadron Collider (LHC), no New Physics (NP) beyond the Standard Model (SM) has so far emerged, even at end of Run 2. There are a handful of socalled "flavor anomalies" [1], but these need confirmation with full Run 2 data. With the Belle II experiment to start B physics data-taking in 2019, what new window could it soon open? We point out how B → μν̄ decay could be an early NP probe at Belle II. Using full dataset, the Belle experiment recently measured B(B → μν̄) = (6.46 ± 2.22 ± 1.60) × 10−7 [2], which constitutes 2.4σ (3.4σ statistical) evidence, hinting at potential enhancement over SM expectation [2] of (3.80 ± 0.31) × 10−7. However, given the B → τ ν̄ rate [3] is consistent with SM, can B → μν̄ really be enhanced? We demonstrate that the answer is in the affirmative, if there exist extra Yukawa couplings in Nature. Such couplings have been of interest recently at the LHC, in the searches of t → ch(uh), which has now reached 10−3 sensitivity [4], and h→ τμ, which indicated a hint in Run 1 data [5], but has since disappeared with 2016 Run 2 data [6]. The implied flavor changing neutral Higgs (FCNH) couplings would affect the Yukawa couplings of the charged Higgs boson H. The Bq → `ν̄` decay branching fraction in SM,


The heterogeneity of discussion networks has been shown to have an effect on citizens' ideas and behavior. In this article, the author undertakes to show that the relative heterogeneity of political discussion networks affects voter coordination on two parties in a single-member plurality system. Specifically, if voters do not have access to polling information about the relative standing of candidates, voters whose discussion networks are ideologically heterogeneous are more likely to coordinate on two parties than voters whose discussion networks are ideologically homogeneous. The author examines this hypothesis using an agent-based model.


The preparation of pure cubic ice without hexagonal stacking faults has been realized only recently by del Rosso et al. (Nat. Mater.2020, 19, 663−66832015533) and Komatsu et al. (Nat. Commun.2020, 11, 46432015342). With our present calorimetric study on the transition from pure cubic ice to hexagonal ice we are able to clarify the value of the enthalpy change ΔHc→h to be −37.7 ± 2.3 J mol–1. The transition temperature is identified as 226 K, much higher than in previous work on ice Isd. This is due to a catalytic effect of hexagonal faults on the transition, but even more importantly due to a relaxation exotherm that was not properly identified in the past.

This research investigates the relationships between advertisement channels, the timing of travel decision making, and the interaction of individual travel decisions based on the destination advertising response (DAR) model. Using a sample of 5,472 American travelers, this study finds that neither the timing of travel decision making nor the channel of advertisement significantly correlates with the advertising response for most trip decisions. However, strong interactions are found between advertising response and restaurant and shopping trip decisions, and between the attractions and events trip decisions. These findings are important in that they suggest that destination marketing programs should bundle these aspects of the trip together when developing their promotional efforts.


Volume 88, Number 1 www.aafp.org/afp American Family Physician 57 A four-year-old boy presented with a pruritic rash on his hands, forearms, and feet that developed one week earlier. He had nonspecific symptoms of an upper respiratory tract infection with rhinorrhea and a subjective fever. He was initially treated with topical steroids, diphenhydramine (Benadryl), and hydroxyzine (Vistaril), but subsequently developed severe swelling, pain, and blistering on his forearms (the right arm was worse than the left). On examination, the patient was ill-appearing and irritable, but afebrile. He had numerous large (3to 6-cm) bullae, some with hemorrhage, on both forearms (Figure 1). The bullae were rapidly evolving on an erythematous base. He had diffuse edema on his right forearm extending to his hand with clawing of the fingers. His pulses and sensation were normal. There was no fluctuance or crepitus with palpation. There was a reticular rash on his right upper arm (Figure 2). His feet were mildly edematous with a faint reticular rash.


Aerosol size distributions and hygroscopic growth were measured using a differential mobility analyzer (DMA) / Tandem DMA (TDMA) system on board a Twin Otter airplane off the coast of Monterey, California during the April, 2003 Asian Dust Above Monterey (ADAM-2003) experiment. The motivation for these measurements was to examine the optical properties of that aged dust upon reaching the California coast. Aerosol light scattering properties of the dust particles and other particle types present were predicted using the measured aerosol size distributions and hygroscopic properties. Within the sampled layers, overall light extinction coefficient was dominated by the larger dust particles. The study-average mass extinction efficiency at 550 ㎚ of the dust aerosol was 1.72 ㎡g?¹, while that of the non-dust aerosol was 2.37 ㎡g?¹. The predicted scattering coefficients were also compared with directly measured scattering to test the accuracy of the measurements and the assumptions used to determine optical properties.


Considering the longitudinal nonlinear model of a hypersonic vehicle including uncertain disturbances, a nonlinear controller based on backstepping method and dynamic inversion method is proposed for solving the tracking control problem. In order to facilitate the control design, the flight vehicle model is decomposed as velocity subsystem and flight path angle subsystem. The command filter is utilized to avoid the problem of "explosion of complexity" which occurs in backstepping method. In order to suppress the disturbances, a novel disturbance observer is proposed for estimating them during the tracking process. A Lyapunov-based stability analysis indicates that the tracking errors are uniformly bounded. Finally, the simulation results demonstrate that the proposed method can achieve superior tracking of velocity and flight path angle references in the presence of uncertainty of the general and aerodynamic parameters.
