Introduction With the increasing daily reliance on electronic transactions, it is essential to have reliable security systems for individuals, businesses, and organizations to protect their information (Vu, Bhargav & Proctor, 2003; Vu, Tai, Bhargav, Schultz & Proctor, 2004). Computer security is largely dependent on the use of passwords to authenticate users of technology (Wiedenbeck, Waters, Birget, Brodskiy & Memon, 2005). However, users are challenged to remember long and random passwords and therefore too often choose passwords that may have low security strength or be difficult to remember (Wiedenbeck et al., 2005; Yan, Blackwell, Anderson & Grant, 2004). As the number of individuals using computers and networks has increased, so has the level of threat for security breaches against these computers and networks. Carnegie Mellon's Computer Emergency Response Team (CERT) (2006) has collected statistics showing that 6 security incidents were reported in 1988 compared to 137, 529 in 2003. Furthermore, CERT (2006) reported that 171 vulnerabilities were reported in 1995 in comparison to 5,990 in 2005 and already 3,997 in the first and second quarter of 2006. In addition, the Federal Bureau of Investigation (FBI) conducted a survey in which 40% of organizations claimed that system penetrations from outside their organization had increased from the prior year by 25% (Ives, Walsh, & Schneider, 2004). The rapid expansion in computing and networking has thus amplified the need to perpetually manage information security within an organization. Events such as 9/11 and the war on terror-ism have also underscored an increased need for vigilance regarding information security. Organizations, government, and private industry are currently trying to adjust to the burden of this heightened need for information security, and, as an example of this, the U.S. Department of Homeland Security (2002) has focused particular efforts on ensuring information security. In light of the current context of universal computing and the realistic threats that exist to organizations' information systems, there is a strong need for more research in the field of information security. In this world of ever increasing technological advances, users of technology are at risk for developing information overload as the number and complexity of passwords and other electronic identifiers increase. Previous investigations of the National Institute of Standards and Technology (NIST, 1992) have suggested that over 50% of incidents that occur within government and private organizations have been connected to human errors. The role that people play in maintaining information security is an important one that the literature has only begun to address. As researchers improve their understanding of how human factors limitations affect information security, they can provide organizations with insight into improving information security policies. Passwords adopted by users are too easily cracked (Proctor, Lien, Vu, Schultz & Salvendy, 2002). In particular, organizations can benefit from research revealing how best to minimize the demands that passwords place on the human memory system while maintaining the strength of a password (Carstens, McCauley-Bell, Malone, & DeMara, 2004). The application of human factors and specifically cognitive theory principles can be used to positively influence system security when organizations follow password guidelines that do not exceed human memory limitations. Ultimately, user memory overload can be minimized when all aspects of a password authentication system have been designed in a way that capitalizes on the way the human mind works and also recognizes its limitations. As Hensley (1999) wrote, "Pass-word(s) do little good if no one remembers them." Nevertheless, the exponential growth in vulnerabilities and security incidents as suggested by the CERT (2006) underscores that the design of password guidelines should be part of a comprehensive approach that still maintains strength of passwords as necessitated by the information technology (IT) community. …


This is a story about art with an opinion. This is a story of empowerment with a sense of humor. This is a story which has many different beginnings, but which we might begin on November 15, 2014, at The Paradise Factory, when Diana Oh premiered her solo concert play, {my lingerie play}. {my lingerie play} begins as a whimsical personal exploration of sexuality and sexual empowerment. On a stage mostly bare of set pieces, the focus of the play is Diana's lingerie, which she repeatedly changes in and out of while telling her story, the costume changes choreographed (bra to tank top to bra) such that she is never nude on stage despite comfortably and confidently undressing before her audience. She begins with her teen sexual awakening, the desire she felt for her first boyfriend displayed through a lacy bra (young Oh's first piece of lingerie) and further expressed through a soft love ballad.Thus a clear format emerges: a piece of lingerie, a story and a song for each of Oh's noteworthy coming of age moments, nine in all. Over the course of the first half hour the audience becomes acquainted with chronological iterations of Oh: a sexually-adventurous-yet-virginity-preserving teen; a more jaded teen who is arrested for shoplifting and struggles to connect to her disappointed immigrant mother; a young college student empowered within her own sexuality, declaring, "I'm not a slut, I'm just a progressive sex-positive queer. That doesn't make me a slut!" Finally the audience is brought to the recent past and introduced to the adult Oh, the multi-faceted artist (self-described as an actor/singer-songwriter/theatermaker) living in Brooklyn. Specifically, Oh tells the story of the night of July 28, 2013, when she was walking home from parking her car and an SUV full of men slowed to a crawl and followed her, the men hanging out of the windows catcalling her. Oh yelled back demanding to be left alone and they turned nasty, calling her a "stupid bitch" as the car crawled beside her down the street.This is the turning point of the performance; for Oh, this catcalling experience made her conscious of the slutshaming she's been experiencing her whole life but strategically ignoring, as women are often taught to do. The next song looks back at her teen years, at all the misogynistic comments she silently shrugged off. A heavy topic, but one Oh addresses with humor, because, as she explained during our interview, "It's a fun time, it's not political art being shoved down your throat." Oh loosens up the audience by encouraging them to join her in the rousing chorus, a simple but effective chant of "Fuck that guy!" Oh's personal shift from passivity to activism is mirrored in the audience, who now shift from their previous role as spectators to a new position of participants: participants who are calling for change but still remember how to laugh as they do so.Next, Oh pulls out a ream of homemade flyers, each a photo of a prominent public figure: Malala Yousafzai, Rosa Parks, Michelle Obama, Barak Obama, and Alec Baldwin, among others. Each flier has a quote of the harassing comments the men in the SUV spat at Oh. She asks, "What makes it ok to talk to any of these people this way? Why is it ok for you to talk to me this way?" She hands the audience the flyers and insists they take them and hand them out to people or post them around their neighborhoods. Audience participation intensifies as Oh invites the women in the audience to repeat the most horrid things said to them on the streets of New York-a task which is simple for the women, who call out many offensive comments in rapid succession. Oh then contextualizes these experiences through global statistics on sexual abuse and various forms of socially sanctioned sexual violence and concludes, "I am here tonight to emotionally rouse you to engage in artistic warfare. To enlist you in this army."The army Oh is referring to is a range of people who have engaged in this collective artistic warfare which Oh began long before performing her solo concert play. …


Hyperbaric oxygenation could inhabit the growth and progression of malignant tumor. It could increase the oxygen delivery to tumors and induce cell cycle synchronization of tumor cells. As a safety and effective radiosensitive protocol, it can be used with radiation therapy to enhance the efficacy of clinical treatments. At the same time, hyperbaric oxygenation was also a main treatment of late radiation injuries. But its prophylactic effect on radiation complications requires further studies.


Spray cooling is a novel solution for high heat flux applications, whose need is becoming apparent with the advance of high power density electronic systems (lasers, radars, etc). The aim of this investigation is to explore thermal management solutions for space‐based systems and the effects of varying gravity on heat transfer. Previous modeling done by Selvam, Lin, and Ponnappan (2006) used a liquid film thickness of ≈ 40 μm on the heater wall. The two‐phase flow modeling is done using the level set method to identify the interface of vapor and liquid as explained in Selvam, Lin, and Ponnappan (2005; 2006). Modifications to the incompressible Navier‐Stokes equations for surface tension, viscosity, gravity and phase change are discussed in detail. The equations are solved using finite difference method. The computed heat flux in thick layers is compared with previous thin layer heat flux. The computed liquid and vapor interface and temperature distributions are also visualized for better understanding of ...

Acute dental pain is the most distressing symptom with which the majority of patients attending dental clinics present. It is a clinical problem to which a range of treatment interventions may be appropriate. In Tanzania, extraction is the most commonly reported treatment option for acute dental pain although most of them would have been saved by endodontic treatment. This paper presents three cases of endodontic treatment performed at Hope Dental Clinic, Mwanza Tanzania. In all cases, patients indicated obvious preference for saving teeth through endodontic therapy. Key words: root canal treatment, case report


Gamma-ray bursts (GRBs) are the most powerful explosions in the universe. Over the past two decades, several GRB energy and luminosity correlations were discovered. These correlations typically involve an observable parameter, like the observed peak energy, Ep,obs, and a non-observable quantity, like the equivalent isotropic energy, Eiso. This paper provides a brief review of GRB peak energy correlations. Specifically, it focuses on the Amati relation, which correlates Ep,obs and Eiso, and the Ghirlanda relation, which correlates Ep,obs and Ey, the total energy corrected for beaming. The paper also discusses the physical interpretation of these relations in the context of the internal shock model.

In existing methods of moving object detection using image recognition technology, an obtained whole image is processed and a moving object is detected in the picture. However, when the moving portion of the scene is hidden by obstacles, recognition of a moving object is sometimes difficult. In this study, we propose a novel method of discriminating moving objects, such as a person or a vehicle. We use only a narrow and tall area of the video, called the Strip Frame Image, for detecting moving portions. By using this method, we are able to obtain patterns of moving objects while avoiding obstacles in a picture. We then classify them by DP matching against previously stored reference patterns in a database for all possible classes (person, bicycle, car, bus). In this paper, we compare several variations of an algorithm used to detect and classify objects passing laterally in front of a security camera. We test both a moving object speed‐independent method and a speed‐based method for constructing patterns for the passing objects. The results show that the relatively simple method of pattern classification by DP matching can be successfully used for classifying graphic objects of a certain degree of complexity. Finally, nonhomogeneity of people's patterns and their subsequent frequent misclassification is addressed not by producing reference patterns for people, but by differentiating them from correctly classified bicycles by the DP distance to the first candidate. © 2010 Wiley Periodicals, Inc.

Mercury is one of important trace heavy metal elements and about 1/3 of mercury in the air comes from emissions of coal-fired flue gas. In this study, we simulated mercury's 4 important reactions of the oxidation kinetics mechanism and got every reactions' rate variations; meanwhile we studied the kinetics of four reactions and got the reacting paths, five pre-exponential factor in different temperatures, reaction activation energy change and reaction rate constant change, a relatively comprehensive homogeneous oxidation model established. Through the above simulation study, the kinetics and thermodynamics parameters of 4 primitive reactions are obtained, having a great benefit for understanding the transformation mechanism of mercury in the process of coal combustion.


Magnetohydrodynamic flow of an incompressible fluid through a plane channel with slowly varying walls and a magnetic field applied transverse to the channel is investigated in the high Reynolds number limit. It is found that the magnetic field can first influence the hydrodynamic flow when the Hartmann number reaches a sufficiently large value. The magnetic field is found to suppress the steady and unsteady viscous flow near the channel walls unless the wall shapes become large.


This paper examines the impact of bank-based financial development on economic growth in Ghana during the period from 1970 to 2014. Unlike some previous studies, the current study uses four proxies to measure bank-based financial development. In addition to these proxies, the study uses a composite index of bank-based financial development derived from these four proxies - using the method of means-removed average. Using the ARDL bounds testing approach, the empirical results of this study show that the impact of bank-based financial development on economic growth in Ghana is sensitive to the proxy used to measure bank-based financial development. The results also tend to vary over time. Overall, our results show that when the ratio of domestic credit extension to the private sector by banks to GDP, and the composite index are used as proxies, bank-based financial development has a positive impact on economic growth in Ghana. However, when the ratio of deposit money banks' assets to GDP is used as a proxy, bank-based financial development has a negative impact on economic growth. These results apply irrespective of whether the estimation is done in the short run or in the long run.


Ambient fine particulate matter (PM2.5) in Guangzhou and Shenzhen were collected and analyzed during days in April, July, October 2004 and January 2005, and 17 PAHs concentrations and the toxicity equivalence concentrations (BaPeq) using benzo [a] pyrene (BaP) as the primary representative of their toxicity were characterized; inhalation cancer risk levels were calculated through linear dose-response model, and then, the sources of cancer risks were studied using Pearl River Delta (PRD) source profile and CMB receptor model. PAHs concentration were 5.87~63.36ng/m3, with the average 28.15ng/m3 in Guangzhou, and 32.68ng/m3 in Shenzhen ambient air, while it was higher in winter and lower in summer; 2.78% and 5.56% samples exceeded GB3095-1996 daily average standard, respectively; and 50% and 61.1% samples exceeded WHO daily average standard. Average inhalation cancer risk level in PRD area was in the range of 1×10-6~1×10-5, which was higher than risks from everyday life, but lower than minimum level for notification. Besides, 3 sources of inhalation cancer risk were apportioned from CMB model, which were coal burning, vehicle emission and biomass burning, among which coal burning made the largest contribution, and biomass burning was much higher in autumn and winter than in spring and summer. The contributions to both OC and BaPeq were very similar.


An actuator capable of selectively breaking or making either, or both, of a pair of electrical circuits, in response to audio signals generated by a hand-held whistle, is provided with a transducer sensitive to the emitting frequency of the whistle, an amplifier for the signal generated in the transducer and a motordriven ram, whose cycle is initiated by the transducer signal, adapted to actuate one of two maintained position switches in the aforementioned pair of electrical circuits. The ram operates the first of said switches whenever the number of audio pulses received by the transducer during its receptive period is odd, for example one; it operates the second of said switches whenever the number of such pulses is even, for example two.


Chicken thrombolytic function was observed in vivo, and the activation of chicken plasminogen by tissue plasminogen activator (t-PA) extracted roughly from chicken heart was studied. The chicken blood clot embedded subcutaneously or the thrombus clotted by thrombin injection in the brachial vein were removed promptly. The t-PA could be extracted when the fresh heart was homogenized with 2M KSCN, O.3M CH3COOK, 5M (NH2)2CO, 3.9-62.5mM and 0.5-2 M MgSO4 solution. The reactivity of t-PA extracted with 62.5mM MgSO4 solution was remarkably enhanced by the addition of CaCl2 in chicken plasminogen (Plg) and t-PA mixture after incubation at 37°C for 4hours. Human urokinase (UK) activation under the same conditions reached to the maximum in one hour. Changing the additional order and the addition of CaCl2 beyond the range of 31.3-125mM were weakened the reaction. Epsilonaminocaproic acid (EACA) inhibited these activation system, being especially effective in activation of Plg. These findings suggest that chicken has a thrombolytic mechanism and a t-PA activation system in fibrinolysis.

Self‐assembly of nanoparticles (NPs) has evolved into a powerful tool for the synthesis of superstructures with tailored properties. The quality, diversity, and complexity of synthesized structures are continuously improving and fascinating new collective properties are demonstrated. At the same time, the rapid development of electron microscopy and synchrotron sources for X‐rays has enabled new exciting experimental approaches to study structure and structure formation in the context of NP self‐assembly. In this review, some recent studies and what can be learned from them are highlighted and discussed. It is started with a general introduction covering important concepts, experimental approaches, commonly obtained structures, the ideas of artificial atoms, and emerging properties are discussed. Recent experimental in situ and ex situ approaches with state‐of‐the‐art electron microscopy and X‐ray diffraction and scattering that helped to obtain a detailed picture of NP self‐assembly processes and resulting structures are then presented.


In this review article we discuss the role of the memory T cells in multiple myeloma (MM) and how they may influence immune responses in patients that received immunomodulating drugs and check point therapy.


Using a highly sensitive amplified enzyme‐linked immunoassay (A E I A) for thyrotrophin (T S H), we have assessed the ability of a single basal measurement of T S H to predict the subsequent response of T S H to TRH in a group of 11 patients with known pituitary pathology and some evidence of hypopituitarism. All patients were clinically euthyroid. Basal levels of A E I A‐T S H ranged from <0‐2 mU/1 ('undetectable') to 0–9 mU/1; within this range there was no correlation with the subsequent T S H levels at 30 min in the TRH test. The T S H response in the TRH test did not correlate with the direct measurements of prevailing thyroid hormone levels (Total T4 or Free T4).


Opportunistic hunting behaviour is characterized by the absence of search phase in a prey acquisition sequence (Kok & Nel, 2004). It is especially common among the members of the Canidae (Macdonald & Siller-Zubiri, 2004). Black-backed jackal (Canis mesomelas Schreber) is a common middle-sized canid occurring in two disjunct populations, one in East Africa and the other in southern Africa (Walton & Joly, 2003). It is a generalist feeder, whose diet comprises small-to-medium-sized mammals, reptiles, birds, eggs, invertebrates, plants, carrion and anthropogenic items (Kaunda & Skinner, 2003; Loveridge & Nel, 2004). Active hunting seems to be more important in the regions with rare or absent specialist predators (Kaunda & Skinner, 2003). Predation on ungulates by jackals is usually limited to fawns (Lawick-Goodall & Lawick-Goodall, 1970; Schaller, 1972; Macdonald, Loveridge & Atkinson, 2004). Present note describes the observation of a successful cooperative hunt of black-backed jackals on adult springbok (Antidorcas marsupialis [Zimmermann]).


Vertical boundary-layer ozone profiles were measured from a tethered balloon platform during the 2003 Antarctic Tropospheric Chemistry Investigation (ANTCI) at South Pole Station, Antarctica. Electrochemical concentration cell (ECC) ozonesondes were used in obtaining 128 ascent and descent profile measurements to about 500m height during 13–30 December 2003. Various data checks and intercomparisons were done to confirm the accuracy of the ozonesondes. The ozonesondes compared well to a surface ozone ultra-violet (UV) absorption monitor located next to the tether balloon site. During the 18-day period, ozonesonde measurement checks at the surface averaged 0.271.0 ppbv higher than the continuous ozone measurements under ambient concentrations ranging from 18 to 51 ppbv. This agreement was also consistent when compared to the nearby NOAA UV-monitor sampling at 17m above ground level during well-mixed conditions near the surface. In addition to the single ECC sonde profiles, five dual ECC ozonesondes were run on the tether platform. Four release balloon-borne ozonesondes were also launched during the project. Under very sharp ozone gradient events, the release ozonesonde (with a rise rate of 4–6m s ) passed through the gradient layer too quickly to capture the detail as measured by the controlled tethersonde at 0.3m s 1 ascent/descent rate. Another method of ozone profiling was also done utilizing the UV monitor at the tether site and a 135-m-long Teflon sampling line with a sampling inlet mounted to and raised with the tethered balloon. The ECC ozonesonde averaged about 0.770.8 ppbv lower than the long-line sampling method from eight profiles. r 2007 Elsevier Ltd. All rights reserved.

maps. Branch also expands his account to the world scale, although he does not engage sufficiently with nonWestern cartographic cultures and could have said much more about China, on which there has been important work. Moreover, because it does not accord with his basic interpretation, Branch is not really able to evaluate sufficiently the role of syncretism in the cartography of empire, as, indeed, in imperialism, both Western and non-Western, as a role. There is a considerable body of scholarship on this subject. For example, for the Americas, a mixture of native and Western mapping conventions and symbols reflected the syncretic character of Spanish imperialism, its ability—alongside the often brutal treatment of Native American society, which was seen as heathen and evil—to adopt and adapt as part of its rule. This was a policy and practice seen also in the way in which, after a period of highly brutal destructiveness, native religious cults were given a place within Christianity. At the same time, adaptation worked both ways. The Native American understanding of geography collapsed the boundary between space and time, recording mythic origins and symbolic power as part of space. This practice was changed as a result of Spanish conquest, not simply because Spain was now the imperial master, but also because the local population swiftly began to follow Spanish practices. They replaced hieroglyphs with alphabetic writing, which transformed the way in which information could be recorded. Branch argues, with much reason, that the abstract understanding of space and the conception of authority in territorial terms applied particularly to the colonial expansion of European powers. As Branch points out, this period coincided with the transformation of Western cartography, although the cause-and-effect has to be handled with care. There is an instructive chapter on New World mapping, and another on peace treaties and political transformation. That which takes the story up to the present is too short to succeed, which is a pity as the topic is important. Having tried to cover some of this territory in The Power of Knowledge. How Information and Technology Made the Modern World (Yale University Press, 2014), I am well aware of the difficulties of linking range and detail, and of avoiding instrumentalism and schemas. Branch is to be congratulated on developing a particular approach with considerable interest.

The utility model discloses a cam molded line of a motorcycle engine, which comprises an air inlet cam molded line, an exhaust cam molded line, cam width, and cam overall height. The cam molded line of a motorcycle engine is characterized in that the curves of the cam molded lines are reasonable and accurate. An included angle of an air inlet cam 1 and an exhaust cam 2 on cams is 105 DEG-128 DEG, and the radius of a basal circle is 22-24 mm. The cam molded line of a motorcycle engine is installed on an engine, the performance of the overall engine can be improved, and the optimum state of the performance of the overall engine is exerted. The cam molded line of a motorcycle engine has the advantages that the noise of the engine can be obviously lowered, the air inlet and the air outlet of the cams are smooth, power is enhanced, the back flow of waste gas can be prevented, and fresh mixing air entering a cylinder is ensured, when the engine works, the optimum efficiency of burning is ensured. The utility model is suitable for an engine with small discharge amount.


follow-up outpatient endoscopic ultrasound, which again confirmed benign gastric folds. Given the patient became asymptomatic, the decision was made to opt out an urgent surgical repair and arrange further reviews to discuss an elective surgical repair of the hernia. This case highlights a rare manifestation of a gastric varix that protruded through the abdominal wall and became a large symptomatic epigastric hernia. Radiologically, this varix originates from prominent gastric varices along the lesser and greater curvature of the stomach, clearly looping into the epigastric hernia (Fig. 1). To the best of our knowledge, this has not been previously published. Generally, most smaller epigastric hernias contain extraperitoneal fat only while larger hernias may contain parts of the bowel, the omentum and sometimes blood vessels. There have been several reports of small vessels found within hernias during surgical repairs. These vessels are mostly non-troublesome and often require simple vessel ligation for intraoperative haemostasis. Regardless of the hernia content, early surgical repair is advocated for any symptomatic epigastric hernias due to concerns of strangulation. In most cases, the decision for surgery is guided by clinical findings, and preoperative imaging for evaluation of hernia content remains controversial. Many factors may affect operation difficulty and surgical planning for an epigastric hernia repair. In this case, because gastric varices generally have higher risks of bleeding, it maybe important that surgeons are aware of these varices prior to operation, as damage may lead to unexpected bleeding during surgery. In addition, because the unusual gastric varix and the marked gastric wall thickening raise concerns of potential malignancy, further investigation prior to surgery is warranted. Both of these matters are uncommon circumstances that demonstrate how preoperative radiological evaluation of a symptomatic hernia may change surgical planning. In summary, this case is possibly the first case report of an incarcerated gastric varix presenting as an epigastric hernia. It reminds surgeons that a simple epigastric hernia repair could become more complicated than expected, particularly larger hernias as these are more likely to have contents other than peritoneal fat alone. In addition, this case demonstrates that CT imaging can be useful when clinical examination of a hernia is unusual and alternative causes, such as malignancy, need to be ruled out. Nonetheless, we agree with the literature that epigastric hernias should be a clinical diagnosis and the routine use of CT imaging for all epigastric masses is not necessary.


In the title complex, [RuCl2(C7H7NO)(C2H6OS)2], the metal ion is at the centre of a distorted octahedral NOCl2S2 coordination sphere. The neutral 2-acetylpyridine ligand binds to the metal ion through the pyridine N and carbonyl O atoms, forming a five-membered chelate ring. The monodentate S-coordinating dimethyl sulfoxide molecules are mutually cis, and the two remaining positions in the coordination sphere are occupied by two mutually trans Cl− ions.


We propose a general-purpose method for detecting cheating in Massive Open Online Courses (MOOCs) using an Anomaly Detection technique. Using features that are based on measures of aberrant behavior, we show that a classifier that is trained on data of one type of cheating (Copying Using Multiple Accounts) can detect users who perform another type of cheating (unauthorized collaboration). The study exploits the fact that we have dedicated algorithms for detecting these two methods of cheating, which are used as reference models. The contribution of this paper is twofold. First, we demonstrate that a detection method that is based on anomaly detection, which is trained on a known set of cheaters, can generalize to detect cheaters who use other methods. Second, we propose a new time-based person-fit aberrant behavior statistic.


In order to generate the switching signals of the power converters for obtaining high quality output voltages, pulse-width modulation is a common method. But, PWM methods produce common-mode voltage (CMV) as a serious problem. In this paper, reduced common-mode voltage methods (RCMV) of 3-D MSVPWM, 3-D NSVPWM and 3-D RSPWM for three-phase four-leg voltage-source inverter (VSI) are introduced, and their pulse pattern and CMV pattern are illustrated. Their performance characteristics are thoroughly investigated to find out whether they are able to maintain the merit of three-dimensional conventional space vector PWM (3-D CSVPWM) in addition to CMV reduction, or not. The switching and conduction loss, linear modulation region and output voltage harmonic distortion factor of each modulation technique is evaluated by analytical methods and simulations. The appropriate PWM method can be selected for needed application by analysis presented in this paper.

An analysis on a passive current sharing characteristics of a multi-phase synchronous buck converter is presented. The passive current sharing method is simple but its characteristics depend on the converter equivalent resistance and PWM uniformity. In this paper, the load sharing and power consumption of the passive current sharing system for the converter equivalent resistance and duty ratio inequalities are investigated through the simulation and experiment.


As agricultural policy has failed to ensure sufficient income, some farm women and farmers try new ways in order to invent new economic bases to improve their household income. The ideas and their way of implementation are often very original, the combining of agricultural and non-agricultural activities innovative. The Federal Institute for Less-favoured and Mountainous Areas has carried out a study on different innovative projects in rural areas which have their roots in agriculture connected with non-agricultural business. The central issues are: Which circumstances lead to the idea and innovative improvement? How is the idea implemented? Is there any support by public and private institutions (extension service, promotion)? The possibilities of alternative income sources on farm units are very manifold. The wide range reaches from selling special products over cooperative trading agricultural products to different services including social services by alternative use of farm resources. Nearly every initiative made use of the existing extension services which lead to the conclusion that consulting is a decisive factor for initiatives. One of the consulting's crucial part is to act as a mediator between the administration and other public institutions on the one hand and the actors in rural areas on the other hand in order to connect the institutions of promotion with the entitled rural population. The initiative was taken for various reasons, the alternative income source develops step by step and sometimes has already become an own enterprise. During innovative processes the actors' activity and commitment is accompanied with recognizing and perceiving their circumstances, chances, and the impact of certain general settings concerning their activities. With regard to changing activities it is very essential to team up with other people in order to create capable organisation structures and to give each other human support. Most of the actors working in rural initiatives have further plans for the future. At the end it was given the impression that one step is following the other and it seems as if the road is made on the move.

A dual‐feed small size full‐metal‐case (FMC) antenna for hepta‐band LTE/WWAN operation in smartphone applications is presented. The antenna proposed here is an integrated part of the full metal case located at the top edge of the smartphone, and it only occupies a small volume of 5 mm × 70 mm × 6 mm. It has two feeding ports that are separately connected to an ON/OFF switch (SW1 and SW2) for controlling the lower and higher operation bands, respectively. For the case when SW1 (ON) and SW2 (OFF), Port‐1 is engaged, and a lower operating band that covers the GSM850/900 operation (824–960 MHz) is achieved. In contrast, Port‐2 will be engaged for the case when SW1 (OFF) and SW2 (ON), and with the aid of a wideband matching circuit, the antenna can induce a higher operating band that can cover the DCS/PCS/UMTS2100/LTE2300/LTE2500 operations (1690–2690 MHz). Detailed design considerations of the proposed FMC antenna are described, and both experimental and simulation results are also presented and discussed. © 2016 Wiley Periodicals, Inc.

Objective To investigate the feasibility, safety and practical value of bone landmark in implantation of permanent pacemaker wire by puncturing axillary vein under X-ray. Methods One hundred and twenty-five patients who needed implantation of permanent pacemakers were divided into two groups: group A (puncturing axillary vein by bone landmark, n=63) and group B (puncturing axillary vein by venography, n=62). Number of times of puncture, time, success rate and complications were compared.Results In group A, the number of times of puncture and the puncturing time were more than those in group B(P 0.01).However, including the time of venography, the total time of puncture was significantly more in group B than in group A(P 0.01).There were no differences of success rate and complications between the two groups(P0.05). Conclusions The methods of puncture axillary vein under X-ray is simple, safe and reliable with high success rate.


BACKGROUND
 Over the past 50 years, dental informatics has developed significantly in the field of health information systems. Accordingly, several studies have been conducted on standardized clinical coding systems, data capture, and clinical data reuse in dentistry.

 OBJECTIVE
 The primary objective of this systematic review was to summarize studies on standardized clinical coding systems and electronic dental record (EDR) data capture in dentistry. The secondary objective was to explore the practical implications of reusing EDR data in clinical decision support systems, quality measure development, and clinical research.

 METHODS
 Based on the definition of health information systems, we divided the literature search into 3 specific sub-searches: "standardized clinical coding systems," "data capture," and "reuse of routine patient care data." PubMed and Web of Science were searched for peer-reviewed articles. The review was conducted following the PRISMA protocol.

 RESULTS
 A total of 43 articles were identified for inclusion in the review. Of these, 15 were related to "standardized clinical coding systems," 15 to "data capture," and 13 to "reuse of routine patient care data." Articles related to standardized clinical coding systems focused on the design and/or development of proposed systems, on their evaluation and validation, on their adoption in academic settings, and on user perception. Articles related to data capture addressed the issue of data completeness, evaluated user interfaces and workflow integration, and proposed technical solutions. Finally, articles related to reuse of routine patient care data focused on clinical decision support systems centered on patient care, institutional or population-based health monitoring support systems, and clinical research.

 CONCLUSIONS
 While the development of health information systems, and especially standardized clinical coding systems, has led to significant progress in research and quality measures, the vast majority of reviewed articles were published in the US. Clinical decision support systems that reuse EDR data have been little studied. Likewise, few studies have examined the working environment of dental practitioners or the pedagogical value of using health information systems in dentistry.


The women's health community is challenged by global social and economic pressures. In order to ensure the salience of their empirical and theoretical research, women's health researchers are struggling with an analysis of what has successfully typified women's health and a critical awareness of the pressures that will mark its future. For many researchers, this has provoked a quest for new women's health paradigms to inform and spur action regarding the future of women's health. Re-theorizing women's health cannot be successful in the absence of an analysis of the epistemological orientation of women's health research. However, little has been done to examine these epistemological roots. This paper examines the historic epistemological foundation of women's health research in order to facilitate an understanding of the theoretical and conceptual underpinnings of women's health. This review is intended to guide future epistemic action necessary to advance the field of women's health research and highlight current efforts that may support work in this field.

ABSTRACT Discussions on the educational potential of school football range from its social acceptance to the pedagogically desirable lessons that can be drawn from it. The aim is to understand the process of institutionalisation in school football and the main formative challenges it entails. An ethnographic multiple case study is presented. The sample consists of 101 schoolchildren of ages six and seven in the autonomous community of La Rioja, Spain. Participant observation, over the course of one academic year, is supplemented by images, interviews and digital social networks to incorporate 21 teachers, 10 coaches and families. The results reveal the construction of an allegorical field among children as they embark upon their path of institutionalisation, with the naivety of their spontaneous play giving way to a form of regulated execution. Institutionalised play exceeds children's developmental resources. The study promotes an effective adaptation of the game, as well as the prioritisation of pedagogical actions that are complementary to school.

Introduction: MELOS (Mars Exploration with Lander-Orbiter Synergy) is a Japanese Martian explorer which is under proposing to be launched around 2020. It will consist of an orbiter for meteorology observation (hereafter, the Orbiter) and a lander for entry-descent-landing demonstration (hereafter, the Lander). As one of the missions of MELOS Orbiter and Lander, we are proposing areodetic observations using space geodetic technologies. We have shown that the four-way Doppler measurements and inverse VLBI can determine the state of the core (liquid or solid), estimate its radius if it is liquid, and figure out the quantities of seasonal surface mass redistribution [1]. For the purpose of reducing the mass and electric power on the Lander, we modified the space geodetic technologies to Doppler measurements with satelliteto-satellite tracking (SST).


approach to understand the process of attribution of actions – or de-agentialization – to the different types of participants represented. Fairclough presents the Dialectal-Relational Approach. In this approach, textual analysis is only a part of semiotic (discourse) analysis. Social elements – orders of discourse, social practices and events – should be understood in their dialectical relationship with the semiotic ones, though cognitive issues are not taken into account. Methodological procedures are part of the researcher's theoretical decisions, since each object of research will allow and even require the selection of different methods. The greatest value of Methods of Critical Discourse Analysis is its ability to present CDA in a concise and introductory way. In this volume, readers will find a fair presentation of CDA's agenda, shared goals and the diversity which characterizes this field of research. It is recommended reading for CDA beginners, for those researchers from different fields of humanities or social political fields who want to get a fix on the school so they know what they will adhere to if they choose to adopt a CDA perspective in their research, as well as for experienced CDA researchers, always interested in the latest developments of this ever evolving and exciting school.

Abstract The objective of the present study is to define whether alkenes, formed during alkane dehydrocyclization, are reconverted to the alkane and to elucidate the role of alkanes in the dehydrocyclization mechanism. In a competitive conversion, an alkene is converted much more rapidly than n -octane (C 8 D 18 ). The lack of H/D exchange indicates that the adsorption of the n -octane is essentially irreversible, whereas some H/D exchange in the added alkene suggests that alkene desorption does occur; however, the added alkene does not desorb as the alkane, in conformity with irreversible adsorption of the alkane. The results demonstrate that the addition of a labeled alkene cannot provide data to establish the validity of the sequential dehydrogenation reaction pathway.


An inexpensive and environmentally benign method for the oxidation of benzyl alcohols is reported employing a vanadium catalyst and using water as reaction solvent under an atmospheric pressure of oxygen.


In two published studies, we used a variant of Neely's (1977) lexical decision paradigm to study shifts of attention and automatic lexical activation in nondemented individuals with Parkinson's disease (McDonald, Brown, & Gorell, 1996; Spicer, Brown, & Gorell, 1994). Arnott and Chenery (in press) noticed differences between Neely's results and the results we observed in our control group that raise questions about some of the conclusions presented in the McDonald et al. (1996) and Spicer et al. (1994) papers. Even when considering the important differences between Neely's (1977) results and those in our control groups, we argue that our results support the conclusions of normal automatic semantic activation and deficient set-shifting in Parkinson's disease. We also introduce the notion of generalized priming to account for some of the priming effects observed in our studies.


We address the problem of constructing a simple holomor- phic eta quotient of a given level N . Such constructions are known for all cubefree N . Here, we provide such constructions for arbitrarily large prime power levels. As a consequence, we obtain an irreducibility


Gradient descent during the learning process of a neural network can be subject to many instabilities. The spectral density of the Jacobian is a key component for analyzing stability. Following the works of Pennington et al., such Jacobians are modeled using free multiplicative convolutions from Free Probability Theory (FPT). We present a reliable and very fast method for computing the associated spectral densities, for given architecture and initialization. This method has a controlled and proven convergence. Our technique is based on an homotopy method: it is an adaptative Newton-Raphson scheme which chains basins of attraction. In order to demonstrate the relevance of our method we show that the relevant FPT metrics computed before training are highly correlated to final test accuracies - up to 85\%. We also nuance the idea that learning happens at the edge of chaos by giving evidence that a very desirable feature for neural networks is the hyperbolicity of their Jacobian at initialization.

The vibration energy can be converted to electrical energy directly and efficiently using piezoelectric cantilever beam based on piezoelectric effect. Since its structure is simple and its working process is unpoisonous to the environment, the piezoelectric cantilever beam can be used in various fields comprehensively. The present paper perform an analysis on the vibration energy harvesting problem of piezoelectric bimorph cantilever beam. The piezoelectric cantilever model has been formulated using the theory of elasticity mechanics and piezoelectric theory. A prototype of piezoelectric power generator is set up to do vibration test, and the electromechanical coupling FEA model under vibration load is built to simulate its output displacement, stress and voltage. The present numerical results of piezoelectric bimorph cantilever coincide well with our related experimental results, which shows the validity of the present FEA model and the relate results.


ALFRED KORZYBSKI wanted a science of humanity. As the title and subtitle of his 1921 book indicate--Manhood of Humanity: The Science and Art of Human Engineering--this was not a disinterested, academic pursuit. Having suffered and seen the suffering of others on the battlefields of World War One, he felt a burning need to promote the growth of "Human Engineering ... the science and art of directing the energies and capacities of human beings to the advancement of human weal." (1) Without a purposeful, systematic, and cooperative effort to create such a science-art, he feared that the energies and capacities of human beings would more likely continue to advance human destructiveness and suffering. (Korzybski eventually abandoned the term "human engineering" and came up with the term general semantics (abbreviated as "GS") to label the methodological fruits of his efforts toward such a science-art.) In Manhood, Korzybski sought to begin a solid foundation for the science of humanity by defining "Man" (used by him at that time as a neutral term for "human being"). He wanted a functional definition: What do humans do that distinguishes them from other forms of life? In answer, Korzybski defined humanity as the time-binding class of life. Humans have the ability to symbolically organize or "bind" their experience and to receive and transmit the products of this effort from one person, group, and generation to another. This gives us humans the potential to benefit from and build upon the experiences and work of those who come before us and to do so at an accelerating rate. After the publication of Manhood, Korzybski sought to understand the underlying basis of time-binding, its mechanism--how does it work? In pursuit of this understanding he made an in-depth study of mathematical foundations and mathematical (symbolic) logic, physics, psychiatry, psychology, colloidal chemistry, neurology, anthropology, and other fields. In the span of two years, from early 1925 into 1927, he studied psychiatric patients at St. Elizabeths Hospital in Washington, D.C., under the supervision of his friend, the distinguished psychiatrist William Alanson White, M.D., who headed that institution. To understand how time-binding works, Korzybski considered it necessary to study its extremes. One end of the continuum of human time-binding behavior was represented by severe psychiatric cases--insanity. The other end was represented by scientists, mathematicians, and other inquirers when working at their best--sanity. To the so-called 'normal' person, hovering between the two extremes, he applied the label "unsane," a term suggested to him by psychiatrist Philip Graven. Considering science and mathematics (including logic) in relation to psychiatric problems and daily life adjustment, as Korzybski did, seemed like a somewhat strange approach to many people (perhaps to some it still does). Writing about Korzybski's work, organizational management theorist F.J. Roethlesberger (who attended a seminar in the 1930s given by Korzybski) wrote: At this time there was considerable interest in comparing the way a child thinks (Piaget) with the way a primitive thinks (Levy-Bruhl) and with the way a neurotic thinks (Freud). Only a genius or a nut would have tried to compare the way a mathematician thinks (Russell and Whitehead) and the way a neurotic thinks (psychiatry). Korzybski was such a man. (2) Korzybski's position may have seemed extreme to those who saw mathematics as dealing with some kind of extra-human, 'transcendental,' platonic realm. Even now (2005), this notion pervades much of the scientific-mathematical community. However, as far back as the 1920s Korzybski viewed mathematics as a language, a form of human behavior. He emphasized mathematics as a product created by and affecting human nervous systems, an exemplar of human time-binding effort. A study of mathematics and those areas of science (e. …


The objective of this paper is to empirically study the selection and application of the Authentic Materials in spoken-Chinese teaching, putting forward the teaching strategies and problems that should be paid attention to. This paper takes input hypothesis and output hypothesis as the theoretical basis, Communicative Approach and Task-based Approach as the basic teaching methods, using teaching experiment, classroom observation and other research methods to collect data from 12 foreign students in the intermediate spoken-Chinese class, and then testify the practicability of the authentic materials. The empirical results suggest that used the authentic materials as an auxiliary material has a significant and positive influence on the spoken-Chinese teaching. Almost all the students accept and are found of learning authentic materials. Experts and peers also agree that teachers should use this kind of teaching material. However, there some problems have been found during the study, such as unsuccessful input performance, inappropriate corpus, inappropriate processing methods of corpus.

Fracture toughness tests of Cr-Mo-V steels were conducted by the CT specimens of various thickness (B=b=a, B: specimen thickness, b: uncracked ligament, a: crack length), and 3-dimensional elastic-plastic finite element analyses of them have been performed. Based on the maximum tensile stress criterion for the cleavage fracture, specimen thickness effect on fracture toughness has been investigated analytically. It is proposed from the analyses that the fracture toughness is equivalent to the plane strain fracture toughness, KIc according to ASTM E399, provided that the following condition is met.B≥350(Jc/σflow) or B≥1.0(Kc(J)/σY)2Where σflow is flow stress, and σY is 0.2% offset yield stress. The thickness required from the criterion is about 40% of that from the requirement of ASTM E399.Ikeda et al. proposed that Pmax=PQ as a validity criterion of KIc, which means that unstable fracture occurs before load-crack opening displacement curve intersects the 5% secant line. The present tests are same results as the proposal. It is demonstrated from the present analyses that the criterion of Pmax=PQ, which were obtained from only experimental results, satisfies the above requirement, B≥350(Jc/σflow).


Abstract TOPSIS is one of the most popular methods of multi-criteria decision making (MCDM). Its fundamental role is the establishment of chosen alternatives ranking based on their distance from the ideal and negative-ideal solution. There are three primary versions of the TOPSIS method distinguished: classical, interval and fuzzy, where calculation algorithms are adjusted to the character of input rating decision-making alternatives (real numbers, interval data or fuzzy numbers). Various, specialist publications present descriptions on the use of particular versions of the TOPSIS method in the decision-making process, particularly popular is the fuzzy version. However, it should be noticed, that depending on the character of accepted criteria – rating of alternatives can have a heterogeneous character. The present paper suggests the means of proceeding in the situation when the set of criteria covers characteristic criteria for each of the mentioned versions of TOPSIS, as a result of which the rating of the alternatives is vague. The calculation procedure has been illustrated by an adequate numerical example.


Department of Materials, Oxford University, Parks Road, Oxford OX1 3PH, Great Britain~Received 8 October 1996!In intermittent-contact mode atomic force microscopy~AFM!, the AFM tip and the harmonically drivensample only spend a brief time in contact, compared to the driving period. As a result the dynamical responseof the cantilever to the shocks received on impact can be described and analyzed in terms of an instantaneousimpact law specifying the loss of kinetic energy on impact. The simplest such law assumes a constant coeffi-cient of restitution and results in the impact oscillator model. The coefficient-of-restitution law is modified toinclude an absolute loss of energy on impact, modeling the effects of adhesion. The stability of single-impactorbits for this impact law is analyzed. The analytical results based on these models are found to be inagreement with experiment. A model of the tip-sample interaction based on the Johnson-Kendall-Robertsmodel of contact incorporating the effects of a liquid meniscus between the tip and the sample is presented.The resulting impact law is found to follow the modified impact law in the presence of adhesion.@S0163-1829~97!06121-8#I.

Describes a device for measurement, control and mapping of magnetic fields. The magnetic sources, mainly coils, are powered by an alternating current; a pick-up coil detects the induced EMF, which is amplified by a phase-sensitive detector. Operating at low frequencies (below 100 Hz) substantially reduces the eddy current effects when conducting materials are near the coils. An application to control the linearity of a magnetic gradient is indicated. The simplicity of this device makes it very efficient in the design of gradient coil systems for nuclear magnetic resonance imaging.


In the use of carotid endarterectomy (CE), the Department of Clinical Neurological Sciences in London, Ontario, follows the guidelines derived from the North American Symptomatic Carotid Endarterectomy Trial (1), which was organized at our institution. In our hospital, three surgeons perform between 100 and 110 CEs and between 10 and 20 cervical carotid stents each year. Most patients are referred from the southwestern Ontario region. Our complication rate for CE is 1% for death and 1% for major stroke. This is how we currently manage patients with the four major ophthalmic indications for CE: 1) Transient monocular visual loss (TMVL): These patients undergo carotid Doppler ultrasound and transesophageal echocardiography (TEE). TEE is preferred over transthoracic echocardiography because TEE allows a better look not only at the left atrium, but also the ascending aorta, which is often an unrecognized source of emboli. If the carotid ultrasound shows hemodynamically significant stenosis, the next step would be cerebral angiography. More recently, contrast-enhanced magnetic resonance angiography (MRA) and computed tomographic angiography (CTA) have been used with increasing frequency. The reason for this shift is that MRA and CTA are less dangerous because they do not involve catheterization and are also cheaper and quicker. If the echocardiogram test shows a plausible source of emboli, the patient would be anticoagulated with warfarin. Eighty-one milligrams of aspirin per day may be added if atherosclerotic carotid arteries were also found, although this increases the risk of bleeding and must be individualized. If the internal carotid artery shows more than 70% stenosis, CE is offered to the patient. If a cardiac or aortic source has been found by echocardiography and the patient has been anticoagulated, the anticoagulation would be stopped to do the CE and then started up again after the surgery. Carotid stenting may be offered if there are significant medical problems precluding CE. If there is 50%–70% stenosis of the internal carotid artery, CE is performed only in men who have also suffered one or more hemispheric transient ischemic attacks, particularly if the transient ocular ischemic attack has occurred within 48 hours. In the 50%–70% stenosis group, less benefit has been shown for women, and surgery is seldom recommended. If there is less than 50% internal carotid artery stenosis, we do not perform CE. 2) Central retinal artery occlusion (CRAO): This condition is also initially evaluated with carotid ultrasound and TEE, as well as a sedimentation rate (to exclude temporal arteritis). Management guidelines for CE are the same as for TMVL. 3) Asymptomatic Hollenhorst plaque (cholesterol retinal emboli): CE is not performed, irrespective of the degree of internal carotid artery stenosis. Such patients undergo TEE to exclude a cardiac or aortic source of emboli and a carotid ultrasound if the TEE is negative. We do not operate on these asymptomatic patients because the stroke rate is very low and there is no difference between medical treatment and CE. 4) Ocular ischemic syndrome (OIS): Patients with OIS typically have severe internal carotid artery stenosis or complete occlusion. Those with more than 70% stenosis are offered CE because it may help in stopping the progression of the ocular ischemia. CE is not offered for total carotid artery occlusion because the success rate of opening the artery in an occlusion is low and there is a high complication rate of stroke.

Several studies (Crespi, 1942; Zeaman, 1949) have shown that performance in instrumental appetitive conditioning is directly related to the magnitude of reward contingent upon the response. Moreover, these studies have indicated that shifts in amount of reinforcement (amount of food or water) lead to rapid and appropriate changes in performance level. The results of a study by Campbell and Kraeling (1953) provide evidence that magnitude of reward is an important variable affecting performance in instrumental escape conditioning. Rats were run in a straight alley in which the startbox and runway provided a continuous 400-v. shock and the goalbox either 300-, 200-, 100-, or 0-v. shocks. Running speed was faster the greater the reduction in shock intensity at the goal. The present study sought to extend these findings on the role of magnitude of reinforcement in escape learning. Specifically, the purpose was to determine whether shifts in the amount of shock reduction would produce changes in escape performance similar to those found in appetitive conditioning with shifts in the amount of goal substance. This question was assessed by training rats initially at one level of shock reduction and then shifting them to different levels during a subsequent testing phase.

ABSTRACT Soybean breeding programs have developed genetic lines with relatively low seed protein, which could negatively impact early seedling growth in low fertility conditions commonly encountered in the field. In these experiments, seed protein mobilization and its regulation in situ in soybean lines with different seed protein levels was investigated. The results showed that rates of nitrogen (N) release from cotyledons were much lower with decreasing levels of N in seed. Patterns of proteolysis of the storage proteins glycinin and β -conglycinin and their subunits were not different, but breakdown rates were slower. Seed N release rates increased somewhat when external N was supplied to roots of the developing seedlings, suggesting the involvement of source/sink controls. The effect appeared to be down-stream from proteolysis, as rates of protein breakdown were not altered. The results indicate that low seed protein levels will lead to reduced seedling fitness in low fertility soil conditions unless fertilizer N is applied.


Two low‐voltage cables, insulated with flame‐retardant ethylene‐propylene‐diene rubber (FR‐EPDM), were removed after being laid in nuclear power plants for many years. We measured the leakage currents flowing through their insulators and found that the resistivity of cable insulation is higher in the two harvested cables than in a similar but new and unused FR‐EPDM one. The reason for this result is discussed in this paper based on a comparison of the leakage currents between new and gamma‐ray irradiated FR‐EPDM sheets. The discussion is continued by referring to our previous papers on mechanical properties and infrared absorption spectra of similar new and gamma‐ray irradiated FR‐EPDM sheets. As a result, it has been clarified that additives such as pigments contained in the cable insulators are likely to act as a source of charge carriers. In addition, the cable insulators became hardened by the long‐term aging in an environment of about 60 °C, which made the ionic conduction difficult and the insulation resistivity higher. © 2023 Institute of Electrical Engineers of Japan.

1 Published By: Blue Eyes Intelligence Engineering & Sciences Publication Pvt. Ltd. Abstract: In this paper is to study the denomination Power quality and large refers to maintaining a proximal sinusoidal power distribution bus voltage at rated magnitude and frequency. This is mainly affected by the generation of harmonics. Even though electronic and non-linear devices are flexible, economical and energy efficient, they may degrade power quality by creating harmonic currents and consuming excessive reactive power. A family of various shunt hybrid active power filters has been explored in shunt and series configurations to compensate for different types of nonlinear loads. They provide controlled current injection to remove harmonic current from the source side of electric system and also can improve the power factor. This paper shows the method of improving the power quality using shunt active power filter with proposed optimized PI. The proposed topic comprises of PI controller, filter hysteresis current control loop, dc link capacitor. The switching signal generation for filter is from hysteresis current controller techniques. With the all these element shunt active power filter reduce the total harmonic distortion. Its source current, compensating current and THD values are studied, then PI control strategy is applied then the differences in THD are compared. The PI feedback compensation design starts with the small signal system's transfer function. Then an optimum constant of PI for a Shunt-APF is proposed and implemented to enhance its response to compensation of harmonics of linear and non-linear loads. The obtained results have demonstrated the ability to compensate the current harmonics effectively under distorted source conditions. The fluctuation in the dc bus voltage of the filter depends on the compensation speed of the outer loop that regulates the dc bus voltage. The proposed shunt active filter model uses balanced linear and non-linear load works successfully lowers the THD within IEEE norms and satisfactorily works to compensate current harmonics. The model is made in MATLAB / SIMULINK and successfully reduces the harmonic in the source current.

The roles of Follicle Stimulating Hormone (FSH) in reproductive physiology have been recognized for a long time. The hormone achieves its functions by binding to the Follicle Stimulating Hormone Receptor (FSHRc) that is strongly expressed in both male and female gonads. Over the last 30 years FSH and its receptor have been discovered also in normal and neoplastic extragonadal tissues including: placenta, uterus, and most recently mammary glands. In neoplasias they contribute to cancer development, cancer cell migration, invasion and neovascularization. Canine mammary gland tumors (MGTs) are the most frequent tumors in intact bitches. Though frequently studied, their pathogenesis is still not completely understood and the presence of FSHRc has not been investigated. The purpose of this study was to evaluate histologically normal and neoplastic mammary glands for the presence of FSHRc using immunohistochemistry (IHC) and in situ hybridization (ISH). Positive immunohistochemical cytoplasmic staining is noticed in epithelial and the underlying myoepithelial cells of normal and neoplastic mammary glands and also in the cytoplasm of chondrocytes in mixed MGTs. In situ hybridization detected the expression of FSHRc in the nucleus and perinuclear cytoplasm of epithelial and myoepithelial cells of normal and neoplastic mammary glands. The signal was observed in the cytoplasm and, to a lesser degree, in the nucleus of chondrocytes in mixed MGTs. Further studies are necessary to elucidate the physiological and pathophysiological roles of FSH and FSHRc in histologically and neoplastic mammary glands and to investigate their potential use as targets for highly specific chemo‐ or immunotherapies of MGTs.


As schools across the country made decisions about how to safely reopen during the COVID-19 pandemic in the Fall of 2020, Catholic schools reopened for in-person instruction more than surrounding public schools. This study analyzes published reopening plans from 136 Catholic schools in 18 different states to explore how schools reopened and how they communicated their plans. Results showed that Catholic schools mostly did not decide to reopen virtually, consistent with local health data trends and public school decisions. Rather, Catholic schools offered in-person education with health and safety protocols in place. Most schools in the sample did not communicate their plans in full on their websites. Plans that were accessible on websites were analyzed based on the National Standards and Benchmarks of Effective Catholic Schools for evidence of the added value of Catholic education during this time.


Sorokin (1994) have shown when alliances can signal commitment in order to achieve deterrence. In Alliance Politics Glenn Snyder seeks to bring together some of these recent developments and bridge the gap between the more contemporary alliance literature and such important earlier works as William Riker's (1962) Theory of Political Coalitions. Instead of competitively testing alternative theories, Snyder borrows from them to create comprehensive frameworks explaining alliance formation and management. The resulting work is an important resource for students of international relations theory as well as for students of alliances.


The «motherese» register (adults'speech to children) is said to be characterized by high vocal pitch compared with speech to other adults, but this assertion is largely based on studies of American English-spealcing mothers. In the present study, sixteen British mothers were recorded interacting with their children aged one to three years and with another adult. These interactions included both a reading aloud and a free speech condition. Half the mothers were professionally trained in child care. Analyses of the audiotapes revealed that this sample of British mothers did, as a group, show significantly higher average vocal pitch as indicated by fundamental frequency (Fo), greater pitch variability and slower rate of speech when addressing their own child compared with addressing another adult. This was true for both the free speech and reading aloud conditions for at least one of the measures of average Fo. Mothers varied considerably, however, in the extent of their motherese modifications, some even lowering their pitch when reading aloud to their children. The motherese modifications were significantly larger for conversational speech than for reading aloud and those mothers who were professionally trained in child care raised their pitch significantly more than nontrained mothers when reading aloud to their children


In this paper, the loading path effect on the elastic-plastic crack-front stress field in a thin plate is investigated. There different loading sequences include one proportional loading and two non-proportional loading paths are applied to the 3-D modified boundary layer (MBL) model under small-scale yielding conditions. For the same external displacement field applied at the outer boundary of the 3-D MBL model, the mode I K field and T-stress field combined as the different loading path is applied to investigate the influence of the nonproportional loading. The results show that for either the compressive or tensional T-stress, the loading path which applied K field followed by T field generates the lower crack-tip constraint. There is only slightly difference between the proportional loading path and the T-stress field following by K field loading path. The results show that it is very important to include the load sequence effects in fracture analysis when dealing with nonproportional loading conditions.Copyright © 2016 by ASME


The deep volcanics formation of Xujiaweizi area is an important gas reservoir in the Daqing oil field. The lithology below the second member of Quan formation is compact and solid with very low drillability, and represents features in the volcanics formation of Yingcheng group. So, it is utmost important to have a full understanding on the lithology characteristics of the deep volcanics formation. On the basis of analyzing the relationship between the well logging data and the parameters of rock mechanical behavior, synthesizing the well logging data and interior core laboratory findings, this study developed a model on the relationship between anti-drillability characteristics and sonic logging data in deep volcanics formation, and by this model acquired the formation characteristics profile, and simultaneously optimized the type of bits to be used accordingly. The result indicates that this model is well fit for this area, and the bit type selected is reasonable through the in-situ test. This model on the anti-drilliablity characteristics of deep volcanics layers can reflect the actual situation in this area very well.

This paper describes an approach to building real-time highly-controllable characters. A kinematic character controller is built on-the-fly during a capture session, and updated after each new motion clip is acquired. Active learning is used to identify which motion sequence the user should perform next, in order to improve the quality and responsiveness of the controller. Because motion clips are selected adaptively, we avoid the difficulty of manually determining which ones to capture, and can build complex controllers from scratch while significantly reducing the number of necessary motion samples.


─ A numerical method for the fully distributed modeling of Field Effect Transistor (FET) excited by an incident electromagnetic field using a Finite-Difference Time-Domain (FDTD) method is described. The transistor is modeled using the fully distributed model which consists of a configuration of the conventional equivalent circuit of the transistor and three coupled lines as each distributed element. The distributed source terms represent the coupling with an electromagnetic field in the equation which can be used in the Electromagnetic Interference (EMI) analysis. As a numerical example, the method is applied to a GaAs MESFET and the time domain results are presented. Index Terms ─ Coupled active transmission lines, Electromagnetic Interference (EMI), Field Effect Transistor (FET), Finite-Difference Time-Domain (FDTD), incident wave, transistor distributed modeling.

We present our results on the expansion dynamics of laser induced plasma created shock wave from stainless steel alloy propagating into ambient air that are characterized by time resolved shadowgraphic imaging. A machinist's scale with periodic surface structures of 30 μm depth and 240 ± 20 μm width having 25 and 64 lpi (lines per inch) is used as a target surface. Laser pulses from frequency doubled Nd:YAG (7ns, 532 nm) with 45 mJ energy per pulse focused to a beam diameter of ~ 1 mm on the target surface are used to generate laser induced shock waves. A fast ICCD camera (DH-734U, ANDOR) with 1.5 ns gating resolution is used to capture the time evolution of SWs into air. The properties of shock waves from structured surfaces are compared to that from a flat surface to understand the contribution of structured surface to shock wave dynamics. The SWs from a flat surface are observed to follow Sedov-Taylor solution during time delay of 0.2 to 20 μs. Contact front discontinuity dynamics were studied at different time scales for flat and structured surfaces The maximum velocity of the SWs has increased from 2.75 to 4 km/s with increasing number of surface structures from 25 to 64 lpi. From the measured radius of curvature of SW's (RSW), the velocity, pressure and temperature associated with the micro explosion of metal surface is estimated using Counter Pressure Corrected Point Strong Explosion Theory.


The Serindit V-2 is a flying vehicle (UAV) that was successfully developed to participate in the Indonesian Flying Robot Contest with a mission to fly at high speed and acceleration. The purpose of this research is to obtain the optimum aerodynamic performance of the propeller and its effect to the flight performance of the Serindit V-2 Unmanned Aerial Vehicle (UAV). The study began by testing the aerodynamic performance of propellers (static thrust value, time consumed, and power consumed) with different sizes of propellers, ranging from 8 inches to 12 inches. From the test results, the 12-inch propeller at 100% throttle generates the highest thrust value of 29.607 N, time consumed of 4.91 minutes, and power consumed of 717.57 Watt. The study was continued by calculating the flight performance with the results that the maximum speed value was 24.11 m/s, the rate of climb was 3.347 m/s, and the stall speed was 14.6 m/s. Finally, the Serindit V-2 UAV was tested to fly using a propulsion system with a 12-inch propeller and varied throttle opening from 50% to 100%. The test results show the vehicle's maximum speed of 24,562 m/s is obtained at a throttle opening of 100%. The climb rate and the flight time at 100% throttle opening is 2,656 m/s and 3 minutes 27 seconds, while the vehicle's stall speed during cruising flight (angle of attack at 1 degree) is 13 m/s. The difference between the theoretical calculation results and the actual test is at least caused by 2 factors. The first is the aerodynamic factor, in theoretical calculations, the overall aerodynamic design of the aircraft is considered very smooth/seamless. This has an impact on the fluid flow that occurs on the aircraft. On the actual conditions, the vehicle has several parts that cause drag, such as the pitot sensor located at the tip of the right-wing, and the ballast located on the left-wing.

ABSTRACT This article examines the multimodalities of banner ads in pervasive marketing and advertising. Departing from the "Double 11 shopping carnival" spectacle on Tmall, this paper conducts a social semiotic and multimodal analysis of banner ads in the Chinese context. As the investigation of the discursive construction process shows, banner ads on Tmall take advantage of human interactivity, intentionality, persuasion and value creation to increase online sales as part of a gamification process while such modalities enhance consumers' shopping experience and sociality. This article provides a synthesis of social semiotics, multimodal analysis and interactivity to guide our analysis of advertising in e-commerce. We argue that apart from traditional marketing strategies, Tmall has extended and obscured the rebellious notion of carnival and used it as a corporation-led strategy to create new cultural forms that encourage spending. This is in line with the rising consumerism in the Chinese society. Our findings will be useful for researchers conducting interdisciplinary studies of multimodal analysis and social semiotics, media and communications as well as advertising and marketing, with a focus on an increasingly globalised China.


Results are presented for the displacements due to Rayleigh waves which are produced by transient normal surface pressure distributions on a semi- infinite elastic half-space. Expressions for the Rayleigh wave displacements produced by a concentrated load on the surface of the medium are used as influence functions to construct, by means of suitable integrations in space and time, the corresponding quantities produced by the pressure distributions from a nuclear burst. Numerical results are presented at various depths and locations in the medium. A discussion of these results and of the applicability of the theory of actual situations is presented. (auth)


In 1950 Greenfield proposed a classification of the various forms of diffuse demyelinating sclerosis on the basis of pathognesis and tissue rea His classification may be restated, but with minor modification as follows: (1) Cases in which, histologically, the appearances are similar to those seen in disseminated sclerosis. Included in this group are cases with concentric demyelination of the Balo type and cases with perivascular islands of residual myelin as in Pelizaeus-Merzbacher's disease. (2) Cases in which the apparent products of myelin katabolism are predominantly metachromatic lipids. Included in this group are those in which there is associated degeneration of the interfascicular oligodendroglia (Greenfield, 1933; Brain and Greenfield, 1950) and those in which the oligodendroglia appear normal in histological perparations (Norman, 1947). (3) Cases in which, histologically, the myelin is replaced partly by neutral fat and partly by some chemical substance which excites an " epithelioid " cell or " globoid " body reaction. Such a condition was first described by Krabbe (1916). (4) Cases which. in the nreyent state of our knowledge, do not fi int above grouus. It-will be n at in the above classification no emphasis is placed upon the familial or nonfamilial natule of the disorders or upon the age Qf ea _eIts. This paper records the results of histological and chemical examinations in three cases diagnosed on macroscopic examination as diffuse cerebral sclerosis. These findings are discussed in so far as they are related to pathogenesis and to the place to be occupied by each in the above classification. The cases were: A, a case with "spongy degeneration" of the cerebral white matter (Canavan); B, a case with perivascular islands of residual myelin (Pelizaeus-Merzbacher); C, a case with numerous " globoid " bodies or " epithelioid" cells in the white matter (Krabbe).

We propose a simple model of columnar growth through diffusion limited aggregation (DLA). Consider a graph GN × N, where the basis has N vertices GN := {1, . . . , N}, and two vertices (x, h) and (x′, h′) are adjacent if |h − h′| ≤ 1. Consider there a simple random walk coming from infinity which deposits on a growing cluster as follows: the cluster is a collection of columns, and the height of the column first hit by the walk immediately grows by one unit. Thus, columns do not grow laterally. We prove that there is a critical time scale N/ log(N) for the maximal height of the piles, i.e., there exist constants α < β such that the maximal pile height at time αN/ log(N) is of order log(N), while at time βN/ log(N) is larger than Nχ. This suggests that a monopolistic regime starts at such a time and only the highest pile goes on growing. If we rather consider a walk whose height-component goes down deterministically, the resulting ballistic deposition has maximal height of order log(N) at time N . These two deposition models, diffusive and ballistic, are also compared with uniform random allocation and Polya's urn. AMS 2010 subject classifications: 60K35, 82B24, 60J45.


Theoretical investigations of -complex ion formation (such as ionic pairs, triplets, dipole-dipole and ion-dipole clusters) in liquid dielectrics at high external electric fields are considered. The consideration has been done on the basis of distribution function method. Rates of ion-ion, ion - ionic pair and dipole - dipole interactions (recombination and dissociation processes) were calculated. The criterion of sediment instability of ion - dipole solution was obtained.
