Hemorrhagic Gastroenteritis, renamed Acute Hemorrhagic Diarrhea Syndrome (AHDS) is a disease often without a known cause. More prevalent in young, small breed dogs, it can strike any dog at any age of any breed at any time. It is thought to possibly be caused by exposure to a novel food item or perhaps an atypical immune response to bacteria. Clostridial species of bacteria may play a role but its significance is not yet understood. Dogs suffering from AHDS are often previously healthy before acutely developing vomiting and hematochezia. Quick recognition of the problem and aggressive treatment by the veterinary team is needed, and with treatment, the prognosis for these patients is good.

Charge trapping effect in silicon-rich oxide (SRO) films was investigated using capacitance versus voltage (C–V), current versus voltage (I–V) and current versus time (I–t) measurements in an Al/SRO/Si MOS-like structure. SRO layers with different thicknesses were deposited. The trapped charge density was found to depend on the thickness of the SRO layers. It was shown that the total trapped charges can be divided into two parts: one part is correlated with the Si nanoclusters located near the SRO/Si interface (interface-NCs); another one is correlated with the Si nanoclusters distributed in the bulk of the SRO layers (bulk-NC). A current peak was observed in the I–V curves in the surface inversion condition. The peak position voltage varies with the thickness of the SRO layers. The current peak is attributed to the charging/discharging of the interface-NCs. The charging/discharging process of interface-NCs was evidenced by a fast decay of current in I–t measurements at the current peak voltage. I–t curves recorded at a large positive voltage are associated with the charge trapping effect of the bulk-NCs. The Coulomb blockade effect was suggested to be the reason of current decay at constant voltage.


book is by and large an excellent reading, both a good introduction for the novice and a useful reference for the more experienced researcher. Introduction In my day job I am a Postmaster. Being a Postmaster involves among other things spam fighting. This basically sums up to configuring, customizing or developing software that identifies spam and deals with it. The way the technology is these days this boils down to regular expressions, Bayes or combining both. I got interested in " Algorithms on Strings " for two reasons: Understand how the " string search " part really works, and if there can be better approaches than just regular expressions and Bayes that can help me with my work. The book deals with " stringology " that is, according to www.stringology.org, the " science on algorithms on strings and sequences. It solves such problems like exact and approximate pattern matching, searching for repetitions in various texts,... etc. There are many areas that utilize the results of the stringology (information retrieval, computer vision, computational biology, DNA processing,... etc.) ". The language of the book impressed me a lot. It is written in English plain enough to be understandable even by non native speakers and although it is full of mathematical proofs the text is not boring at all. The figures and their captions are very very helpful in understanding how the presented algorithms work, sometimes being more valuable than the text itself. I think it would not have been an easy task for me to follow the discussion without them. Like the backcover of the book says, it is not for undergraduates. The typical undergraduate curriculum does not take one further than the first chapter. The next eight chapters all step on the first one, of which they are elaborations and more advanced treatments on specialized subjects. Chapter 5 for example presents a concise treatment on tries (and in case anyone wonders why someone outside theory is interested in tries, I refer them to the BSD TCP/IP code where PATRICIA is used). This is not an easy book. It is a good book, but one needs pencil and paper to really follow it. Time after time I drew automata on paper in order to really " get " it. The pseudocode on the other hand is very helpful. If one does not want to follow the theory and proofs and just wants …

The multiphase and multilevel motor drives have attracted more and more attention during the last decade since they offered advantages of high-power rating, lower voltage and current stresses in semiconductor switches, higher fault-tolerant ability, compared to the conventional two-level three-phase drives. This paper presents a model predictive current control (MPC) for a T-type three-level inverters fed dual three-phase permanent magnet synchronous motor (PMSM) drives. The key is to propose new space voltage vector synthesis method for voltage vector candidates in MPC scheme of the T-type three-level inverters fed dual three-phase PMSM drives. The proposed scheme can alleviate the computation burden of MPC and suppress the current harmonics induced from inherent property of dual three-phase PMSM. The experimental results are given to verify the validation of the proposed scheme.


Teaching materialization of competitive sports(竞技运动教材化) and new localization of school sports goal proposed by scholars of our country do not favor the realization of school sports basic goal.As the school sports instructional items are too limited,new teaching resources and new sports items conforming to the time demand should be developed.The ignorance of athletics technol-ogy goes against the educational laws of physical culture and the formation rules of movement skills.Simplifying athletics movement rules and athletics movement games does no good to the spread and development of athletics movement culture in schools.


A soil bin-single wheel tester has been designed to study on soil-tire interaction. The soil bin features a 23-m long by 2-m wide by 1-m deep bin and an electric drive system is used to pull a carriage by two chains. The carriage has a capacity of testing three prototypes of tools in each run. Then a single wheel testing device was projected, built, instrumented and evaluated. The test tire on the moving carriage under the towing test mode was made to rotate and engage onto the soil surface in the soil channel through a chain drive system. Under the driving test mode, the test tire on the moving carriage was powered to rotate by a motor and an inverter with an additional pull provided by a chain mechanism connected to an electromotor. Respective transducers were positioned at various localities interfaced to a data acquisition system to measure and save tire horizontal and vertical forces, tire sinkage, tire speed and carriage speed. The performance of the testing facility was evaluated and validated during some initial tests. Static calibration tests on various associated transducers showed excellent linearity with coefficients of determination (r 2 ) of close to 1. The comparison between observed and predicted values of motion resistance ratio using Wismer and Luth model showed an accuracy of ±20 per cent.


A good understanding of how meteorological conditions exacerbate or mitigate air pollution is critical for developing robust emission reduction policies. Thus, based on a multiple linear regression (MLR) model in this study, the quantified impacts of six meteorological variables on PM2.5 (i.e., particle matter with diameter of 2.5 µm or less) and its major components were estimated over the Yangtze River Basin (YRB). The 38-year (1980–2017) daily PM2.5 and meteorological data were derived from the newly-released Modern-Era Retrospective Analysis and Research and Application, version 2 (MERRA-2) products. The MERRA-2 PM2.5 was underestimated compared with ground measurements, partly due to the bias in the MERRA-2 Aerosol Optical Depth (AOD) assimilation. An over-increasing trend in each PM2.5 component occurred for the whole study period; however, this has been curbed since 2007. The MLR model suggested that meteorological variability could explain up to 67% of the PM2.5 changes. PM2.5 was robustly anti-correlated with surface wind speed, precipitation and boundary layer height (BLH), but was positively correlated with temperature throughout the YRB. The relationship of relative humidity (RH) and total cloud cover with PM2.5 showed regional dependencies, with negative correlation in the Yangtze River Delta (YRD) and positive correlation in the other areas. In particular, PM2.5 was most sensitive to surface wind speed, and the sensitivity was approximately −2.42 µg m−3 m−1 s. This study highlighted the impact of meteorological conditions on PM2.5 growth, although it was much smaller than the anthropogenic emissions impact.


We solve the field equations of modified gravity for $f(R)$ model in metric formalism. Further, we obtain the fixed points of the dynamical system in phase space analysis of $f(R)$ models, both with and without the effects of radiation. Stability of these points is studied against perturbations in a smooth spatial background by applying the conditions on the eigenvalues of the matrix obtained in the linearized first-order differential equations. Following this, these fixed points are used for analysing the dynamics of the system during the radiation, matter and acceleration dominated phases of the universe. Certain linear and quadratic forms of $f(R)$ are determined from the geometrical and physical considerations and the behaviour of the scale factor is found for those forms. Further, we also determine the Hubble parameter $H(t)$, Ricci scalar $R$ for these cosmic phases. We show the emergence of an asymmetry of time from the dynamics of the scalar field exclusively owing to the $f(R)$ gravity in the Einstein frame that may lead to an arrow of time at a classical level.


The World Health Organization estimates that 287 million of the 9.2 billion people on the planet are blind. They still struggle to complete their daily tasks, so it is important to take the necessary steps with the help of new technology. It is intended to be able to read and read written text. Such inventions provide a solution to motivate visually impaired students to complete their education despite the difficulties. Its main goal is to develop new ways for blind people to read texts and facilitate their communication. The reader's first task is to scan text images, convert them to spoken text, and listen to the audio through headphones or speakers connected to the reader. Text in images was recognized using Optical Character Recognition (OCR) technology with OpenCV and Tesseract. Text-to-speech (TTS) technology was used to convert text to speech. However, the reader has some drawbacks, such as: Only English is supported, and the minimum font size to capture images is 16. In the future, it is possible to support multiple languages and improve the design.

It is expected that massive runaway electrons (REs) may be generated during plasma disruptions in ITER. An uncontrolled loss of such REs can cause localized damage of the Plasma Facing Components (PFCs). Then a Disruption Mitigation System (DMS) is being developed in ITER to control or suppress RE generation. One of the most promising techniques employed in the future DMS is the injection of High-Z impurities [1]. Although the avalanche mechanism of RE production is anticipated to be the dominant mechanism in ITER [2], the avalanche multiplication of the runaways after the thermal quench (TQ) still requires a seed RE current. One of the mechanisms of RE generation recognized in the past as an important RE seed provider is the diffusive leak of electrons from the maxwellian core into the high-energy "runaway" region under the influence of the driving electric field [3] ("Dreicer generation"). In ITER the cold post thermal quench plasma will be characterized by the large amount of partially ionized impurities. This makes the problem statement on RE generation different from that in [3]. In the present study we solve numerically the Fokker-Planck equation for electron distribution function to calculate the Dreicer RE generation in ITER-like plasmas taking into account electron interaction with partially ionized high-Z impurities according to model [4]. The comparison with the existing results for fully-ionized plasmas and the implications for ITER are discussed.


As reported in a previous article, growing apices of the xanthophycean coenocytic alga, Vaucheria terrestris, bends away from a unilateral blue light (BL) source, if they are simultaneously irradiated with strong background BL in a solution containing 1-4 mM Ca 2+ . Since the negative bending is a function of the product of the external Ca 2+ concentration and the fluence rate of background BL, a BL-induced Ca 2+ -influx at the apex was hypothesized to be the cause of the phototropic inversion. The present report provides strong evidence for this hypothesis. (...)

In recent years, in accordance with the rapidly increasing number of smartphone users, various social problems have started to occur. Examples of these problems are the overuse of smartphones and bad usage habits of smartphone users that can cause new social problems such as smartphone addiction and other smartphone related diseases. With the aim of preventing these social problems, this paper proposes a new smartphone addiction and disease prevention system. This system was developed by collecting and analyzing smartphone usage patterns. This proposed system analyzes the usage patterns and working hours of smartphone users in real time. If the detected smartphone usage patterns reach a dangerous level, the system will send warning messages to the user. This will enable users to recognize the unhealthy situation in advance by themselves. In addition, this solution could possibly prevent smartphone addiction and other smartphone related illness by preventing overuse and encouraging abstinence from using smartphones to the extent that it becomes harmful to the user.


I Have recently been examining a series of specimens of Silurian slates from Scotland, specially collected because of the very intense shearing they have undergone. These and the accompanying other rocks are all crushed and torn out in a most remarkable degree, and the microscope shows how severely their constituents have been acted upon mechanically. Yet the crystalline and mineralogical development is seen to be but very moderate indeed. The micaceous mineral is all in one plane, and transverse sections, in polarized light, show that it is a felted, wavy, and puckered mass of interwoven flakelets, with chloritic substance intimately diffused among it, and still more apparent in separate little streaks and lenticles. The small amount of quartz present is rolled out into long, thin lenticles also. But the micaceous mineral itself is not at all far advanced, either as to size of its flakes or the nature of the mineral. It is still an impure, rather deeply-coloured greenish-yellow substance; not any of it has arrived at the stage of muscovite, and dehydration shows, in a remarkable manner, how very considerable its impurity still is. In its original condition, the slate gives sections which present a very uniform appearance under the microscope. The colour is the same all over, and the only indication of the presence of bands of varying nature is found in a very slight increase, in some layers, of the coarseness of grain and of the number of quartz-lenticles, and in the diffusion of the chloritic substance. But after heating the specimen, the effects seen in the sections are most striking. There are now many bands of different colours, yellow, red, greenish-brown, and brown, presenting very strong contrasts, and showing that noticeable differences in chemical composition must have existed in different thin layers of the seemingly homogeneous slate. Not only the interwoven chlorite, but also the micaceous mineral, has taken on these tints in very decided degrees. It must have been unusually impure. It has lost, after heating, nearly all its action in polarized light.

In this chapter we examine the various claims that have been made regarding Language Learner Strategies (LLS). We adopt a chronological perspective in order to give a sense of the unfolding debates surrounding this area of research. We track LLS research from its inception in the 1970s and early studies, through to its more developed forms in the last decade of the twentieth century and to the present day. Interwoven with this historical overview is an account and an assessment of the critiques of strategy research which have appeared in the literature. We end at the point we have reached in the debate as to the desirability of strategy research and a series of challenges facing future researchers. We begin by setting a historical context.


The systematic investigation of the crystallization of cephaloglycin and cephalexin leads to a better understanding of the part that pseudopolymorphic crystal transitions play in the analysis, processing, and formulation of these and many other pharmaceutical compounds.The employment of solubility versussolvent composition diagrams to detect various crystal forms of compounds is discussed.This appears to be a convenient and sensitive method for detecting new crystalline phases.It should find application whenever crystallizations are performed with more than one solvent, and particularly when instability of the compound at elevated temperatures prevents the use of conventional thermal methods or when poor crystal development limits the use of microscopic methods.Interpretation of vapor pressure-composition relationships for various crystal forms of these compounds points to the advisability of obtaining such data for all pharmaceutical solids.


We report a total of ten cases of thymoma(in StageⅠ/Ⅱ according to the Masaoka's classification) performed thymo-partial thymectomy by anterolateral incision with video-assisted thoracoscopic surgery. The subjects were three men and seven women,with an average age of 58±11.0 years old. Of the ten patients, three underwent associated resection of other organs, another three had postoperative complications,one had phrenic nerve paralysis associated with combined resection,and one had been suffering from atrial fibrillation before the operation. In accordance with the WHO classification,the most common histopathological diagnosis was Type AB in five cases(50%),and six (60%)was noted in StageⅠ according to the Masaoka's classification after the operation. An average operating time was 92.3±39.2 minutes. An average operative blood loss was 20.5±34.1 ml. An average time of a chest tube drainage was 1.50±0.85 days,and an average hospital stay was 7.4±4.62 days. There have been no signs of recurrent disease in all the patients. Thoracoscopy-assisted thymo-partial thymectomy by anterolateral incision is considered to be a minimally invasive and safe operative procedure for selected thymoma patients.


─ MIMO systems have attracted great attentions because of their huge capacity. The hardware implementation of MIMO decoder becomes a challenging task as the complexity of the MIMO systems increases. This paper presents hardware/software co-design architecture targeted on a single FPGA for two typical lattice decoding algorithms. Two levels of parallelisms are analyzed for an efficient implementation with the preprocessing part on embedded MicroBlaze soft processor and the decoder part on customized hardware. The system prototypes of the AV and VB decoders show that they support up to 34.2 Mbps and 3.15 Mbps data rate at 20dB SNR respectively on XUP Virtex-II pro developing board with an xc2vp30 FPGA, which are 19 and 16 times faster than their respective implementations on a DSP. The performance in terms of resource utilization and bit error rate are also compared between these two algorithms.


The purpose of this work is to use a renormalized quantum scalar field to investigate very early cosmology, in the Planck era immediately following the big bang. Renormalization effects make the field potential dependent on length scale, and are important during the big bang era. We use the asymptotically free Halpern–Huang scalar field, which is derived from renormalization-group analysis, and solve Einstein's equation with Robertson–Walker metric as an initial-value problem. The main prediction is that the Hubble parameter follows a power law: , and the universe expands at an accelerated rate: a ∼ exp t1 − p. This gives 'dark energy', with an equivalent cosmological constant that decays in time like t−2p, which avoids the 'fine-tuning' problem. The power law predicts a simple relation for the galactic redshift. Comparison with data leads to the speculation that the universe experienced a crossover transition, which was completed about seven billion years ago.

Newborn Care Poster Presentation Purpose for the Program Avoiding skin injury is critical to optimizing outcomes in hospitalized patients. High rates of pressure injuries have been reported among patients in pediatric and adult intensive care units (ICUs), but less data on incidence or prevention are available for neonatal ICU patients. The aim of this quality improvement program is to standardize the skin care of patients in our neonatal intensive care unit (NICU). Proposed Change An interdisciplinary team was formed in an acute care, Level IIIC, all referral NICU. This team is responsible for weekly rounds on patients to assess and document skin injuries, collect demographic information, provide education to bedside caregivers, and provide recommendations for skin care. Implementation, Outcomes, and Evaluation The team underwent standardized training over a 4-week period to detect and stage pressure injuries. Weekly skin rounds began in July 2011. Initial staff resistance to the change in routine was overcome by education via in-services and self-studies on skin injury prevention; this led to a gradual shift in perception and skin rounds are now an accepted routine. There was also tremendous support from administration and nursing, respiratory, and medical leadership, which helped integrate skin rounds into the unit culture. Between July 2011 and August 2013, the skin injury team rounded on a median of 47 patients per week for 100 weeks, for a total of 4,672 patient assessments. The overall incidence of Stage II or greater pressure injuries was 2.79 injuries per 1,000 patient days. Stage II pressure injuries accounted for 64.5% of the injuries assessed. Stage III pressure injuries accounted for 2.8% of the injuries. Suspected deep tissue injuries accounted for 21.5% of the injuries. Injuries that could not be staged accounted for 3.7% of the injuries. Mucosal injuries accounted for 7.5% of the injuries. No Stage IV pressure injuries were detected. The greatest cause of pressure injuries was respiratory devices followed by immobility. The incidence of pressure injuries after the formation of the unit-based skin team increased significantly (from a baseline of 0.49 injuries per 1,000 patient days), which demonstrated an improved detection of injuries with standardized skin rounds. Implications for Nursing Practice We have created the largest database of skin injury in the NICU by means of an interdisciplinary team focused on skin injury prevention, education, and regular skin assessments of all infants. This database provides a stable platform upon which to build and measure prevention strategies. This skin care approach could serve as a model for other institutions.


Open System Authentication Method, Shared Key Method, Mac Based Authentication Method are very hard to use in wireless network that needs security. So now, many researches have been performed about 802.1x and user authentication method applying PKI. but certificate verification protocol has been used abolished list called CRL since it's first usage of PKI, there were still has a problem about distribution point. This paper applied CVS to use CA direct not to use CRL and OSCP server in order to improve this problems. Also It suggested the system that can make authentication steps more shorter using authentication server and Mutual authentication system by public certificate(small size/low speed wireless terminal can access to wireless network fast and safely)


The Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) is an imaging spectrometer that measures spatial images of the total up welling spectral radiance from 400 to 2500 nm at 10 nm spectral intervals. Quantitative research and application objectives for surface investigations require conversion of the measured radiance to surface reflectance or surface leaving radiance. To calculate apparent surface reflectance an estimation of aerosol optical depth is required for compensation of aerosol scattering and absorption across the spectral range. Determination of other atmospheric characteristics such as atmospheric water vapor and surface pressure is also required. In this paper we describe a set of algorithms to estimate aerosol optical depth, atmospheric water vapor, and surface pressure height from the AVIRIS measured radiance. Based upon these determined atmospheric parameters we described an algorithm to calculated apparent surface reflectance from the AVIRIS measured radiance using a radiative transfer code.


Abstract We used data from 91 stream reaches in the Missouri River drainage of Wyoming to determine whether abiotic and biotic factors were related to the abundance of four cyprinid species associated with turbid-river environments: flathead chub Platygobio gracilis, sturgeon chub Macrhybopsis gelida, plains minnow Hybognathus placitus, and western silvery minnow H. argyritis. The abundance of these cyprinids was positively related to the percentage of fine substrate in a reach and inversely related to the percentage of gravel substrate, the percentage of large rocky substrate, and the abundance of exotic piscivores. Differences in substrate composition and abundance of exotic piscivores were largely explained by the presence and location of large, main-stem impoundments. Reaches without any large impoundments in their watershed had a high percentage of fine substrate, high catch rates of turbid-river cyprinids, few exotic piscivores, and little gravel or large rocky substrate. Reaches with a downstream i...


In this paper, the authors propose a new experimental spatial matrix identification method. This method is to identify, determine in other words, a set of the mass, damping and stiffness matrices that can represent the dynamic characteristics of an objective structure in a frequency range from DC up to some frequency of interest from experimental FRFs. The theory of the method is proposed at first. Then, the validity of the theory is verified by an identification of a frame structure, which is made of steel components.


Abstract Design and development of advanced materials for high performance applications and bringing these materials into use are the most challenging tasks of modern engineering. Ceramic–metal composites are natural candidates for these demanding applications due to their very attractive properties. Various processing techniques have been used to fabricate ceramic–metal composites. Melt infiltration is one of the preferred techniques to fabricate ceramic–metal composites. Ceramic–metal composites have been fabricated using non-reactive and reactive pressureless and pressure assisted processing techniques. Owing to the inability of current processing technology to fabricate complex shaped ceramic–metal parts with desired microstructures and properties, additive manufacturing is becoming an increasingly important processing approach. Additive manufacturing in combination with infiltration methods was used for the fabrication ceramic–metal composites with a complex geometry.


The ultimatum game (UG) is an outstanding game which shows how people behave against rational strategies suggested by game-theory analysts. In the classic kind of this game, one person plays as "proposer" who is supposed to split a determined amount of money between himself/herself and another person who called "responder". If the responder accepts the suggested amount of money, then the proposal in implemented and the game is terminated but if the responder rejects the proposal both will receive nothing and the game is terminated. Different extension of this game i.e. dictator game, pirate game, three person game, etc. have been introduced by researchers and also different factors such as size of stakes, fairness, age, etc. have been studied in order to better analyze the behavior of the players throughout the game. Since this game could be used as the base of many economic and/or social theories and on the other hand a comprehensive review over extensions and/or different factors have never been published, in this paper a comprehensive review of the related papers covering around 30 years of time interval is provided.


Mineralization of urea-form fertilizer materials was studied in soils at two different pH levels and five different temperatures. Results show that the nitrogenous materials decomposed very slowly but progressively throughout the incubation period of 14 weeks, and that nitrate was the main product formed. The rates of nitrate production from the urea-form compounds were, in general, from 2 to 5% higher in soil with an initial pH 5.7 than in soil having an initial pH 7.0. At the end of the incubation period, the quantities of nitrate formed from the two urea-form compounds were about equal, amounting to 20, 28, 40, 50, and 58% of the total nitrogen added at 10, 15, 20, 25, and 30 °C respectively. The laboratory results suggested that the urea-form materials studied here could be of only limited value to plants if applied to soils with temperatures below 15 °C during the growing season.


Working—Class women in the Weimar Republic faced a complex and disorienting political situation. The revolutionary government granted women the right to vote in November 1918, but then ousted many women from their wartime jobs with the assistance of the trade unions and factory councils. The growing radicalism of working women during the latter phases of the First World War, marked especially by heavy female participation in the general strike of January 1918 in the munitions industry, was checked by the expulsion of women from exactly those sectors of employment which were most conducive to radicalism, the large plants in the metal industry. In other sectors, however, there was a large expansion of union membership among women during there volutionary period from November 1918 until May 1919, and many women in light industry and rural areas simultaneously joined unions and the Social Democratic Party (SPD). Urban women working in large plants who might have supported the Independent Social Democratic Party (USPD) or the Communist Party (KPD) were fired to make room for returning war veterans, and this led to an eclipse of female radicalism from 1919 until 1923. The inflation of 1923 again activated many women who were attracted to the Communist Party by its neighborhood price control committees, and women took an active part in pressuring food shops to keep prices down and joined in plundering shops or stealing from the fields of landlords and peasants when hunger left them no alternative. The economic chaos of 1923 pushed even women in light industry to the left, and textile workers in Berlin, Saxony, and Thuringia gave the Communists a majority in union elections.

Abstract : The sampling component is a small glass roller wrapped with a strip of filter paper dampened with ethylene glycol. It is rolled over the contaminated surface to sample the activity. After a run, the contaminated roller is dropped immediately after contact with the surface into a counting vial containing a scintillant solution, and the activity is assayed. The apparatus is small enough to be operated in a conventional glove box. The precision of the measurements is influenced by the texture of the surface sampled. Precision measured on a smooth optical quartz surface using a nonvolatile tracer, promethium(143), as a contaminant, was determined to be = 2%. The precision for tirtium sampling from a relatively coarser, nonuniform metal surface was approximately = 25%. The apparatus can be used to study the rate of tritium desorbed from the surface, which allows estimation of the cumulative hazard effect of multiple contacts with the surface during the desorption period. Representative samples of metal surfaces exposed to tritium show that after exposure, desorption is exponential, decreasing to an 'equilibrium' amount within a few hours. Multiple contracts with these desorbing surfaces did not seem to significantly alter the desorption process.


Improving performance of a mobile application by offloading its computation onto a cloudlet has become a prevalent paradigm. Among mobile applications, the category of interactive data-streaming applications is emerging while having not yet received sufficient attention. During computation offloading, the performance of this category of applications (including response time and throughput) depends on network latency and bandwidth between the mobile device and the cloudlet. Although a single cloudlet can provide satisfactory network latency, the bandwidth is always the bottleneck of the throughput. To address this issue, we propose to use multiple cloudlets for computation offloading so as to alleviate the bandwidth bottleneck. In addition, we propose to use multiple module instances to complete a module, enabling more fine-grained computation partitioning, since data processing in many modules of data-streaming applications could be highly parallelized. Specifically, at first we apply a fine-grained data-flow model to characterize mobile interactive data-streaming applications. Then we build a unified optimization framework that achieves maximization of the overall utilities of all mobile users, and design an efficient heuristic for the optimization problem, which is able to make trade-off between throughput and energy consumption at each mobile device. At the end we verify our algorithm with extensive simulation. The results show that the overall utility achieved by our heuristic is close to the precise optimum, and our multiple-cloudlet mechanism significantly outperforms the single-cloudlet mechanism.


Huyndai Powertech, Co. Namyang, Korea(Received March 7, 2014 ; Revised May 13, 2014 ; Accepted May 14, 2014)Abstract − Frictional heat greatly influences the friction behaviors during clutch engagement. Therefore, theengagement of a wet or dry clutch is frequently not under control by the frictional heat. In a wet clutch, the fric-tional temperature also specially needs to be controlled, and in many cases, the clutch material is selected to pre-vent a temperature rise from the friction between friction pad and separator. However, only the selection of theclutch material cannot ensure sufficient control of the temperature rise by the friction. The groove pattern on afriction pad is designed for more flow rates of transmission fluid between the contact gap of clutch pad and sep-arator for the cooling effect. In this work, grove patterns are designed for more flow rates out of the contact gapbetween friction pad and separator plate. Selected groove design shows the improvement flow rates of trans-mission fluid through both inner and outer radius, where most of the transmission fluid flows through the outerradius when the clutch is engaged due to the centrifugal force in conventional wet clutch groove. Several com-parisons of the amounts of frictional heat generated on clutch pads are made in order to verify the decrease ofthe temperature rise according to the flow rates along the groove patterns.Keywords − clutch engagement (클러치 체결), frictional heat (마찰열), groove pattern (그루브 패턴), heatconductio (열전도), transmissio fluid (TF, 변속기 오일), wet clutch (습식클러치)


In the wake of a potentially damaging earthquake, every affected welded steel moment-frame building should be assessed to determine whether it poses a safety risk. A straightforward, multi-step process has been developed to streamline this formidable task. This paper provides an overview of this procedure and repair techniques as published in FEMA-352, Recommended Post-earthquake Evaluation and Repair Criteria for Welded Steel Moment-Frame Buildings. The evaluation procedure, developed as part of the SAC Steel Project, begins with screening to rapidly identify those buildings unlikely to have been damaged. Subsequent steps help identify buildings that have sustained sufficient structural damage to compromise future performance and to determine appropriate actions regarding building occupancy and repair.


This chapter examines what Christian identity means for actual classroom practice with regard to pedagogy, ethics, and modeling. The survey respondents' approaches fell into the categories of spiritual addition and Christian transformation described in the previous chapter. The spiritual addition professors mentioned that they added a particular spiritual practice such as devotional Bible reading or prayer, or shared the personal story of their own Christian conversion to their classes. In contrast, Christian transformation educators demonstrated three unique pedagogical approaches related to: (1) their meaning and purpose, (2) their content, and (3) their method of interpretation. Fundamentally, the chapter argues that Christian teachers must view their task as more than helping advance a profession, providing students with academic capacities, or creating citizens. They must understand themselves and their students as God's image bearers, helping them to experience human flourishing both inside and outside of the classroom.

Surgical skills are an amalgamation of meticulousness, precision, and fine motor skills. The ocular surgery in specific also needs advanced hand–eye coordination as most surgeries are performed under microscope. A fundamental component for developing competency in ocular surgery is undergoing a structured surgical training program.[1] Unfortunately, high heterogeneity in surgical exposure over time and across locations is a current challenge in ophthalmology residency training.[2] Concurrently, it is essential to ensure patient safety and provide high‐quality patient care without compromising the resident's educational mission. Traditionally, surgical teaching has centered on the concept of graded responsibility and exposure to a high volume of cases based on the apprenticeship model. However, it has been widely established that training based solely on the apprenticeship model is not an ideal approach for technical skills training.


Achieving growth and maintaining success in a firm is an intended strategy that needs to be carefully crafted throughout the business cycle. Both technology strategies and business imperatives must be continuously reviewed in order to keep a firm innovating at a steady phase. A firm's stature and financial statutes do not provide a license to seize innovation opportunities. Even well established firms can flounder and stumble and fall. The ability to innovate is a critical success factor for many firms. Innovation capability is not necessarily a determinant of a firm's size or economic dominance, although the ability to adopt and change innovation strategies provides dominant firms with high agility. A firm's corporate and innovation cultures are vital in shaping and responding adequately to the call of innovation in the market place. This case study illustrates how a major telecommunication company may sustain or lose its innovation capacity in an intensely competitive global market.


This article examines the history of American historical societies by focusing on the Wisconsin Magazine of History (WMH), published by the State Historical Society of Wisconsin (now known as the Wisconsin Historical Society). The first half of the paper relates the history of American state historical societies and their publishing ventures until the founding of the WMH in 1917. The first American state historical societies were private organizations of elite men, and their publications were meant to notify similar organizations of their proceedings. The advent of public state historical organizations opened membership to a much broader segment of society, but the professionalization of the study of history in the late nineteenth century brought about a more rigorous approach to the writing of history. Throughout the twentieth century, the SHSW and similar organizations have sought to balance an appeal to a broad public and a scholarly approach to history in publications such as the WMH. By examining issues of the WMH from 1917 to 2000, as the author has done in the second half of the paper, one can see how the publication, with audiences clearly in mind, tilted toward one side of this balance or the other in its design and content.


Cardiovascular disease (CVD) causes significant deaths worldwide, of which 17.3 million deaths per year are due to CVD. The use of Ultrasound is necessary to see the abnormalities. The study will segment Carotid Artery segmentation on the Ultrasound image by using the U-Net-based architecture of non-local means-based speckle filtering (NLMBSF). The images will use NLMBSF to reduce speckles, and the data set will be divided into two parts, namely the dataset, which using NLMBSF and not NLMBSF. After that, doing training to create a U-net model, the training data model results will be searched with the best Accuracy. The obtained result of the study is an accuracy value of 97.74%, dice value is 87.22%, and a loss of 0.0107 on data that does not use NLMBSF. Still, it got different data results using NLMBSF, namely 97.6% accuracy, dice value is 84.06% and 0.0138 value loss.

In this work, we investigate structural and optical properties of metalorganic chemical vapor deposition grown wurtzite InxGa1−xN/GaN epitaxial layers with thicknesses that are close to the critical layer thickness (CLT) for strain relaxation. CLT for InxGa1−xN/GaN structures was calculated as a function of the InN content, x, using the energy balance model proposed by People and Bean [Appl. Phys. Lett. 47, 322 (1985)]. Experimentally determined CLT are in good agreement with these calculations. The occurrence of discontinuous strain relaxation (DSR), when the CLT is exceeded, is revealed in the case of a 120 nm thick In0.19Ga0.89N layer by x-ray reciprocal space mapping of an asymmetrical reflection. The effect of DSR on the luminescence of this layer is clear: The luminescence spectrum shows two peaks centered at ∼2.50 and ∼2.67 eV, respectively. These two components of the luminescence of the sample originate in regions of different strain, as discriminated by depth-resolving cathodoluminescence spectr...


The utility model relates to a belt fracture detection device receives drop bar (5), spring (4), gyro wheel (3), response iron plate (four to six -tenehs), inductive switch (8) and fixed plate (2) constitution. The pressure that gyro wheel (3) received spring (4) is along with belt (9) rolls, when belt (4) breaking occur, and gyro wheel (3), drop bar (5) and the whole downstream of response iron plate four to six -tenehs, when responding to iron plate (four to six -tenehs) and touch inductive switch (8) down, the belt signal that splits is exported in inductive switch (8). Its advantage is that simple structure reacts rapidly, exports to switching signal, can directly be received by the system to emergency reaction makes rapidly, not only but the fracture condition of on -line measuring belt also can detect the condition that the belt is lax, tension is not enough at any time.


The existence of the interactions between thermodynamics and dynamics in tropical cyclone development has been long speculated. This study explores some of the most intriguing aspects related with the interactions between thermodynamics and dynamics during cyclogenesis, using the data from two recent eld campaigns. The authors insightfully linked the strati cation with the vertical mass ux and thus the convergence of mass, vapor and vorticity. Furthermore, this link was nicely used in supporting the top-down perspective of tropical cyclone development, which features with the midlevel vortex that tends to stabilize the atmosphere. This study also suggests some counter-intuitive ideas on TC genesis, e.g., the enhanced low-level vorticity aggregation can spin down the protective mid-level pouch circulation, given certain strati cation pro les. The last sentence of the above paragraph is not a true statement. In this study we found that more stable troposphere is linked to a stronger low-level vorticity convergence, but have not implied how does the low-level vorticity convergence a ects the mid-level vortex. This subject becomes more important in a mature, warm core vortex and we have not speculated anything regarding this in the current manuscript. The paper was also written with great clarity and overall reads very smooth. The following are some comments and questions: 1. In the original draft and the reply to Dr. John Molinari, the authors have shown considerable e orts in addressing the subjectivity of averaging area choice when analyzing individual disturbances. But in some circumstances this subjectivity can become a more severe issue. I agree that in some circumstances the subjectivity in choosing areas for analysis can become a more severe issue. Though, this goes for objectively selected areas too (as discussed in the manuscript). We don't think this is an issue in our analysis, however, since the areas chosen cover most of the convective activity associated with the respective disturbances.

There are very few studies addressing pain mechanisms in frontotemporal lobar degeneration (FTLD), as well as the possible contributions that the study of the neurobiological basis of pain in dementia can confer to the knowledge of general pain physiopathology itself. Semantic dementia (SD) is a form of FTLD in which patients progressively lose conceptual knowledge about the world, affecting their ability to understand sensory stimuli such as non-verbal sounds, tastes, and smells. A 60-year-old right-handed, businessman, presented 4 year history of word finding difficulty together with impaired word comprehension. Day-to-day and personal autobiographic memories were unaffected. He did not present depression signs. Patient has developed marked histrionic traits: if brushed by a family member he may react as if in severe pain, an exaggerated reaction to tactile stimuli. He keeps claiming for long time after any bruising, even the very mild ones. Orthopedic investigation resulted negative many times. During physical exam, more precisely during face tapping (to elicit primitive reflexes), he became angry with the manipulation, assumed that behavior as violence, reacting with obscenity and prohibiting me to keep the neurological exam even despite all my warnings that was important to me to continue my job in order to elucidate his health problem. In the neurological exam, except for the alterations in semantic memory, no other abnormalities were seen. His MRI is showed in Figure. A SPECT scan showed bilateral hypoperfusion in temporal lobes. His score on the MMSE was 26/30. Digit Span was 7 forward, 4 backward. His day-to-day memory was unaffected. Constructional ability was preserved. His spontaneous speech was fluent and anomic with normal syntax, phonology and prosody. On verbal fluency he did 3 animals in one minute. Performance on sentence repetition of Boston Diagnostic Aphasia Examination was normal. Comprehension of syntax was normal, however, oral and written comprehension of single words were impaired. Our patient presents an exaggerated reaction to tactile stimuli. Patients with SD were also significantly more likely than


Counterfeit medicines are fake medicines which are either contaminated or contain the wrong or no active ingredient. Up to 30% of medicines in developing countries are counterfeit. Using Supervised Machine learning techniques we build a predictive model for predicting sales figures given other information related to counterfeit medicine selling operations. Thus, by predicting the values we can identify these illegal operations and counter them. In this paper we have also mentioned the importance of Data mining and Machine Learning algorithms with some comparison analysis.


In the ELMO bumpy torus, neoclassical transport coefficients depend critically on the ambipolar electric field. These coefficients, calculated for arbitrary radial electric fields, are applied in a one-dimensional radial-transport calculation which, for the first time, treats the electric field self-consistently. This purely classical model predicts many features of experimentally operation including a steady-state solutions with radially inward-pointing ambipolar fields.


A motion vector generation apparatus (1) wherein, when motion vectors are sequentially generated for a plurality of images, a target point is determined at a sub-pixel level in any of the plurality of images, a corresponding point corresponding to the target point is searched at a sub-pixel level in another image different from the aforementioned image, and a motion vector is calculated on the basis of the target point and the corresponding point. Then, the corresponding point is defined as a new target point, and the process is repeated to sequentially generate motion vectors. Therefore, the motion vector generation apparatus (1) can obtain consecutive motion vectors by searching the corresponding points at a sub-pixel level in the plurality of pictures.


The subject matter of the present study is the possibility of generating extremely high pressures by the method of laser-driven thin foil colliding with a foil at rest. Some simulation studies were made to determine the degree of increase in pressure produced as a result of a collision process, as compared with the ablation pressure generated in a laser irradiated foil. It has been observed that there exists a chance for successful profiling of the pressure pulse produced during the collision process, by appropriate selection of the parameters of the experiment.


The measurement of physical properties from single molecules has been demonstrated. However, the majority of single‐molecule studies report values based on relatively large data sets (e.g., N > 50). While there are studies that report physical quantities based on small sample sets, there has not been a detailed statistical analysis relating sample size to the reliability of derived parameters.


Based on the investigation of fracture distribution characteristics,the influence of fractures on injection was analyzed in Taizhao area,Daqing Oilfield.The results show that four sets of structural fractures with high dip angle were developed in Putaohua low-permeability sandstone reservoir,whose orientations respectively were east-west,northwest-southeast,south-north and northeast-southwest.Fractures have little reservoir capacity but make main roles on seepage.Affected by foctors such as present stress field,the starting pressures of above fractures on the wellhead respectively are 15.1,19.6,27.8 and 28.0 MPa, which show the different starting sequence of the fractures.Now,the injection pressures in the study area basically exceed the starting pressure of east-west fracture,and the reflection characteristics of injection are quite clear.According to seepage characteristics of different sets of fractures,it is available to improve development effect by adopting linear injection well pattern,dynamic adjustment injection,cyclic injection,intermittent injection between layers and intermittent pumping after high water cut wells shut-in,and making further consummation injection-production system.


Abstract ALTHOUGH the literature contains a number of reports on thermostabilization of shell eggs (Bornstein and Lipstein, 1962b), none of them attempts to elucidate the mode by which internal egg quality is stabilized. It is commonly believed that similar to "flash" heat treatment, the purpose is to coagulate a thin film of albumen, immediately beneath the shell membranes, which acts as a moisture and gas barrier. According to this hypothesis heat treatment is not unlike oil processing, except that in the latter case the shell is sealed externally while in the former it is sealed internally. Funk (1950), however, demonstrated that the egg white thinning process is more effectively retarded by thermostabilization than by oil treatment. The purpose of the present paper is to present data which contradict the above hypothesis, that thermostabilization acts by sealing the shell internally. MATERIALS AND METHODS Stabilizing Internal Egg Quality. Percentage weight loss and Haugh …


The existing research on product innovation mainly focused on the impact factors, paths and impact effects, etc.. However, the topic of how a company chooses product innovation strategy to cope with the competitor's is rarely studied. This article uses evolutionary game theory approach to model and study the choice of product innovation strategy between two competitor-oriented companies. Game analysis results show that evolutionary stable strategies exist in four scenarios and radical product innovation strategy is the only way to realize long-term development of the companies and market. In order to win in the competition, companies should adopt specific product strategy according to different situations, and they should pay more importance to radical product innovation strategy to maintain long-term competitive advantage. KEYWORD: radical innovation product strategy; incremental innovation product strategy; competitor- oriented companies; evolutionary game analysis component

With the development of society and the rapid development of the Internet, there are currently about 100 million web pages and 100 million hyperlinks, and in the future, the number of web pages and hyperlinks will also intensify. How to make this huge Internet better used by people has become a common concern of the international community. In recent years, with the acceleration of the reform of China's basic education curriculum, people have become more and more aware of the special status and superiority of art education in overall education, and the general consensus that "lack of art education is an incomplete education." Therefore, this paper proposes the construction of a platform for digital art education under the "Internet+" environment. This paper first introduces how to perform data mining in the Internet era, and proposes an interactive data fusion algorithm and model for Internet and crowdsourcing. Then, a statistical analysis was made on the preschool art education syllabus of 20 colleges and universities in different provinces and cities. The experimental results have shown that there are eight undergraduate colleges and universities that have not written syllabuses for College Aesthetic Education majors in art courses, and they still account for 40% of the total sample size. This shows that some Chinese colleges and universities have not paid enough attention to the art courses of College Aesthetic Education majors, have loopholes in curriculum management, and neglected teaching staff.


Balancing conflicting experimental physics and machine accelerator physics demands with realistic Interaction Region (IR) magnet designs for the proposed eRHIC electron hadron collider at BNL requires new magnet concepts and careful attention to detail. Here we review work to develop conceptual IR magnet designs appropriate for the eRHIC Ring-Ring accelerator configuration.


The study was carried out under warm and temperate (Csa - Kopen Gegger classification) ecological conditions of Turkish province of Hatay during 2010-2011 using saffron (Crocus sativus L.) corms of three different circumference by planting them at 5 and 15 cm depths. Saffron corms were divided into three categories based on circumference; large: more than 8 cm, medium: 6-8 cm and small 4-6 cm. The number of corms, number of flowers, fresh stigma yield, number of leaves, number of harvested corms and their weight were evaluated after harvest. The results showed that the number of flowers were positively affected by their circumference at both planting depths. Surface planted corms showed proportionally increased regeneration of new cormlets. The stigma yield was positively affected using different corms circumferences in the second year, but had no significant effect at different depths. Increased weight of harvested cormlets was noted on corms planted at 15 cm depth during the 2nd year. Second year planting at 15 cm depth showed markedly increased corm circumference, improved number of flowers, stigmas yield compared to the these parameters noted after first year planting with planting.


Let $\mathbb {V}$ be a polarized variation of Hodge structure over a smooth complex quasi-projective variety $S$. In this paper, we give a complete description of the typical Hodge locus for such variations. We prove that it is either empty or equidistributed with respect to a natural differential form, the pull–push form. In particular, it is always analytically dense when the pull–push form does not vanish. When the weight is two, the Hodge numbers are $(q,p,q)$ and the dimension of $S$ is least $rq$, we prove that the typical locus where the Picard rank is at least $r$ is equidistributed in $S$ with respect to the volume form $c_q^r$, where $c_q$ is the $q$th Chern form of the Hodge bundle. We obtain also several equidistribution results of the typical locus in Shimura varieties: a criterion for the density of the typical Hodge loci of a variety in $\mathcal {A}_g$, equidistribution of certain families of CM points and equidistribution of Hecke translates of curves and surfaces in $\mathcal {A}_g$. These results are proved in the much broader context of dynamics on homogeneous spaces of Lie groups which are of independent interest. The pull–push form appears in this greater generality, we provide several tools to determine it, and we compute it in many examples.


This article proposes a new architecture of combined neural networks, which is used to recognize the radar targets from radar range profiles. Combined neural network consists of an invariant neural network and a neural network classifier. The efficiency of these networks is proved by the experimental results. Proposed combined neural networks can be applied to divergent areas of pattern recognition, such as recognition systems of periodic signals, images, numerical series....


In Kazakhstan the basic hydrocarbon deposits are located in undersalt complex that lied down up to 4-5 km. Section is complicated by salt dome tectonics and have got a significant vertical and horizontal velocity gradient and curvatures of geological boundaries. Consequently, CDP travel-time curves are essentially non-hyperbolical and standard. processing steps means are not effective. Oil-bearing stratum spreading and yield of bore-holes are not always controlled by structural factor only. High cost of drilling up to such depth requires a high reliable geophysical forecast.


In recent years, an innovative vibro‐modulation technique has been introduced for the detection of contact‐type interfaces such as cracks, debondings, and delaminations. The technique utilizes the effect of nonlinear interaction of ultrasound and vibrations at the interface of the defect. Vibration varies the contact area of the interface, modulating a passing ultrasonic wave. The modulation manifests itself as additional side‐band spectral components with the combination frequencies in the spectrum of the received signal. The presence of these components allows for the detection and differentiation of the contact‐type defects from other structural and material inhomogeneities. The vibro‐modulation technique has been implemented in the N‐SCAN® damage detection system providing a cost effective solution for the complex NDT problems. N‐SCAN® proved to be very effective for damage detection and characterization in structures and structural components of simple and complex geometries made of steel, aluminum, ...


On the basis of high-resolution seismic data, a high-frequency framework was established for the H12 well area. Combined with drilling analysis and sedimentary facies research, we analyzed favorable lithological development areas. Interpretation of subdivision layers in favorable lithological development areas, optimization of target sand bodies, and multi-attribute analysis techniques, we accurately describe the distribution of lithological bodies. By using spectral decomposition technology to perform insider characterization of lithological bodies, and combine with actual drilling to predict the distribution of effective reservoirs, we have summarized a set of effective methods for identifying such lithological traps.

We support labour contents as an absolute and reliable measurement unit and as an accounting procedure that expresses the real costs and profits of the economic system. As far as the labour capacity of expressing real social costs and profits is concerned, we highlight the inaccuracy in the basic economic data derived from the deviation of the rate of profit in terms of prices with regard to that which is calculated for labour values and we also demonstrate that the price system far from being independent of these values, is supported by them. Thus, there is no redundancy between price and value systems. These results are obtained in a simple model under the following assumptions: simple – not joint - production is considered where only circulating capital exists. Every good or service considered, is a basic commodity; there is only one quality labour.


What is the relation between the rules of war covered by 'the war convention' and the source of their normative authority? According to Michael Walzer, these rules have normative authority by virtue of being widely established in theory and practice and conforming to our moral sensibilities. It is striking that his influential account of just war has a conventionalist grounding similar to his more scrutinized general theory of justice. Indeed, we should question whether a shared moral understanding is an adequate basis for morally obligating parties who might challenge the rules under the war convention. I argue that rules of war need the support of moral judgments whose normative authority is ultimately not conventional in nature. Reasonable objections to the war convention exert pressure to revise its standard principles or to admit that these principles lack general moral force. Such objections, inchoate though they may be in international political discourse, seem a source of commonly voiced skepticism of morality in international relations. Debate about the merits of alternative principles of just war has the advantage of engaging with this skepticism. This opens up the possibility that less powerful or more conscientious parties could play a constructive role in a public and more democratic discourse of just war.


We demonstrate that lossy plasmonic resonances of nanoparticles are broad enough to cover the majority of the solar spectrum and highly efficient for absorbing sunlight. In analytical calculation, we choose a titanium nitride nanoparticle as a lossy plasmonic nanoresonator and present that sunlight absorption efficiency of a titanium nitride nanoparticle is higher than gold and even black carbon nanoparticles. The experiments demonstrate that titanium nitride nanoparticles dispersed in water have high efficiency to heat water and generate vapor than carbon nanoparticles by converting sunlight into heat. Our results open great possibilities for efficient solar heat applications with titanium nitride nanoparticles.

As part of a general investigation of the biology and morphological variation of the Hottentot population, this study deals with the karyotype analysis of a sample from that population. The modal number overall is 46; however, a high percentage of aneuploid cells, both hypomodal and hypermodal, is found. The rate of increase of aneuploidy with age is considered in detail. The rates for hypomodality with age for Hottentot females are positive and significantly higher than those for other populations previously reported.

A fragment of chromatin is described. The fragment occurs in the two Hottentot males and in 22 of the 23 Hottentot females studied. Cells from the one non-steatopygic female successfully cultured show fragments, as do cells from a Bushman female. In the Hottentots the average incidence of the single anomaly equals or exceeds the incidence of the total of all chromosome lesions in published studies giving control data.

Metaphases from five individuals are figured, and several unusual features of the chromosomes are described.

The findings are discussed in terms of functional integration at a cytological level karyotype pictures to be expected in hybridization between demes long isolated, and microevolution of the Hottentot population.


This article reviews the literature on office-housing linkage programs. Though linkage programs enjoy considerable popular support, they tend to highlight existing political anatagonisms between neighborhood and downtown interest groups. City officials wishing to implement a linkage program need to delicately balance those interests while safeguarding against possible legal pitfalls and attending to numerouspolicy design questions. Evidence suggests that linkage is likely to be a viable option for only a few cities experiencing a rather narrow set of economic and political circumstances. However, where it can be implemented, it can be very successful

Several factors, including dwindling ocean fish stocks, the high price of wild fish, and the commercial success of enclosed fish farming, have rekindled interest in enhancing natural stocks by the release of artificially raised individuals into the ocean environment. Due to ecosystem interrelationships and constraints, enhancement of fish stocks, irrespective of the purpose, generally has far-reaching biological consequences. Therefore, it almost invariably also has economic and social consequences well beyond those of relevance to the stock enhancers themselves. There are, in other words, external effects associated with ocean stock enhancement. This article is concerned with these problems. It develops a simple theoretical model for investigating the essential external effects of ocean stock enhancement. On the basis of this model, it is demonstrated that a stock enhancement industry will generally not release the correct number of individuals into the ocean. More surprisingly, perhaps, the analysis also shows that if stock enhancement is going on, conventional fishing activity should be modified. The article goes on to discuss institutions and mechanisms that would correct the problem. Theoretically, the appropriate mix of taxes and subsidies could, in principle, do the job. Another, probably more efficient method, consists of the implementation of individual property rights in the form of tradable harvesting and fish release quotas or licenses.


Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that data from the cell adhesion experiment shown in Fig. 11 were strikingly similar to data appearing in different form in Fig. 6B in another article written by different authors at different research institutes [Huang Z, Li J, Du S, Tang Y, Huang L, Xiao L and Tong P: FKBP14 overexpression contributes to osteosarcoma carcinogenesis and indicates poor survival outcome. Oncotarget 7: 39872‑39884, 2016].  Owing to the fact that the contentious data in the above article had already been published prior to its submission to Molecular Medicine Reports, the Editor has decided that this paper should be retracted from the Journal. The authors were asked for an explanation to account for these concerns, but the Editorial Office did not receive a reply. The Editor apologizes to the readership for any inconvenience caused.

Indigenous tribes have faced systematic alienation from their ancestral domain and common property resources in land, water and forest resources due to the application of Eurocentric Anglo-Saxon epistemology of positivism in counter opposition to the narratives of local traditions of the tribes based on customary law. This is true of the treaty concluding Native American tribes as well as the numerous scheduled tribes of India, who were ruled mostly by Ex-feudatory Chiefs under British paramountcy. The symptomatic similarities of resource appropriation lay in the structured political and economic designs of the colonial state system in the early part of American and Indian history. In the Post 1950's phase it was the extension of earlier legal stereotypes that perpetuated this system to cause great impoverishment and marginalization of the tribal people. Contemporary history of tribal resistance movement therefore rejects the legal legacy of colonial state and demands the progressive inclusion of the right to self determination. It demands better compensation packages on an inter-generational basis, market rates and share-debenture stakes in assets lost, codification of customary rights and their eventual restitution, better resettlement and rehabilitation policy and legislative guarantees through Acts for tribal people experiencing involuntary displacement for public purpose takings under eminent domain laws etc. In fact the academic and activist militancy has forced the United Nations to pass important resolutions on Indigenous concerns and nation states are following suit. This trend has forced international donor and financial organizations to make the 'equator principle' mandatory for all project funding. Therefore any realistic attempt to integrate tribal ethos into development praxis must sincerely begin the exercise by making the tribes real stakeholders at the core of the processes of development rather than mute spectators standing on the powerless periphery.


The graphics industry has advanced very far from the days of pixelated 2D images on small monitors. The main focus of graphics hardware work has been achieving the most realistic images while maintaining the interactive nature of realtime applications. This focus has matured and today's modern graphics card is able to process millions of triangles and vertices to form complex 3D images with a variety of realistic effects. However the realism achieved is mainly due to a bunch of "hacks." Many of the algorithms used in realtime graphics applications favor speed over the quality of work produced. These "hacks" allow us to just barely get by without increasing the computation time significantly. To better meet the needs of todays consumers, the graphics industry will need to spend time updating the poorly looked over quality metric. Using ray tracing, we can upgrade quality. Current graphics APIs such as OpenGL and DirectX use an overly simple lighting model to compute the effects of light on a scene. Ray tracing is a way to more accurately compute lighting effects on surfaces by simulating how rays are transported around the scene. This is more realistic since it not only takes into account how the initial light from a source bounces off an object, but also takes contributions of light which have been reflected off of objects. This enables ray tracing to be very good at rendering highly reflective and shadowed surfaces [1]. Many algorithms have been developed to implement ray tracing efficiently on a standard sequential CPU. Most ray tracers are implemented by shooting out rays of light from points on the screen into the scene. This way only rays of light which contribute to the rendered image will be computed. This still happens to be very computationally intensive for any CPU today. The computation time prevents ray tracing techniques from getting into main stream graphics cards since images can no longer be rendered in real-time. However there is nothing inherently stopping this computation from happening in parallel [1]. The "embarrassing amount of parallelism" which can be taken advantage of in ray tracing is the focus of my project. Today many companies are moving towards multiprocessor systems and multicore chips. This provides much more hardware and computatoin power to use in parallel for ray tracing applications. So it is important to see how the feasibility of using ray tracing for more applications changes with these advancements in technology.

ABSTRACT Spiritual leadership gains attention amongst researchers for closing the gap between achieving personal and organisational goals. Despite documentations that spirituality undergirds head teacher's actions leading inclusive schools, research still remains thin in understanding how spirituality underpins leadership for inclusive education. This paper draws on the philosophy of critical realism to offer a conceptual tool that identifies head teachers' spiritual actions in their efforts to include ethnic minority students. This is done through multiple qualitative methods collection from an in-depth case study at a multicultural primary school in Cyprus. The critical realist framework helps uncover head teacher's spiritual actions in a more systematic, structured and holistic way. It reveals that head teachers' spirituality supports the goals of inclusion and occurs in at least four interrelated and emergent ontological levels (psychological, social, cultural and policy levels) which are set in four scaler levels from microscopic to macroscopic (sub-individual, micro, meso and macro levels). This framework problematises mono-dimensional and reductionist understandings of spirituality in leadership. The paper concludes by suggesting solutions to enrich leadership programmes for inclusive education with fostering leaders' spirituality at different ontological levels.
