distress—including depression and anxiety—in adults with cancer (doi: 10.1200/JCO.2013.53.4495). The guideline is based on an adaptation of the Pan-Canadian Guideline on Screening, Assessment, and Care of Psychosocial Distress (Depression, Anxiety) in Adults with Cancer, also using the ADAPTE method. The ASCO Expert Panel who developed the guideline was co-chaired by Barbara L. Andersen, PhD, Professor at Ohio State University Comprehensive Cancer Center—Arthur G. James Cancer Hospital and Richard J. Solove Research Institute, and Julia Howe Rowland, PhD, Director of the Office of Cancer Survivorship at the National Cancer Institute. Key recommendations are: • All patients with cancer and cancer survivors should be evaluated for symptoms of depression and anxiety at periodic times across the trajectory of care (and assessment should be performed using validated measures); • Supportive care services (e.g., education about normalcy of stress in the context of cancer, signs and symptoms of distress, stress reduction strategies, and fatigue management) should be offered to all survivors; • Depending on the levels of symptoms reported, more specific treatment pathways are recommended in the guideline—and the guideline notes that failure to identify and treat anxiety and depression in the context of cancer increases the risk for poor quality of life, and potentially increased diseaserelated morbidity and mortality; • Health care providers should assess follow-through on referrals and compliance with treatment recommendations (as the guideline notes, it is common for patients with symptoms of depression and/or anxiety to disregard such recommendations); and • Health care practitioners implementing the recommendations should first identify the available resources in their institutions and community for the treatment of depressive and anxiety symptoms (availability and accessibility of supportive care services being important in preventing or reducing the severity of these symptoms). T SURVIVORSHIP GUIDELINES Continued from page 9 Nearly nine years after the Institute of Medicine recommended that cancer patients completing primary treatment receive a survivorship care plan, only about five percent of oncologists are actually providing them. That is the conclusion of a study now available online ahead of print in the Journal of Clinical Oncology (doi: 10.1200/ JCO.2013.51.7540). There are currently about 14 million cancer survivors in the United States, and that number will continue to rise with improved survival rates and an aging population. The study, funded by the National Cancer Institute and the American Cancer Society, used data from the 2009 Survey of Physicians' Attitudes Regarding the Care of Cancer Survivors (SPARCCS), which was completed by 1,130 oncologists and 1,020 primary care physicians practicing general internal medicine, family medicine, and obstetrics-gynecology. First author is Danielle Blanch-Hartigan, PhD, MPH, a Cancer Prevention Fellow in NCI's Office of Cancer Survivorship. The results showed that: • 64 percent of oncologists said they always or almost always discussed survivorship care recommendations with survivors; • Only 32 percent of oncologists discussed with survivors who they should see for cancer-related or other follow-up care; • Less than five percent of oncologists provided survivorship care plans to their patients; • Only 12 percent of primary care physicians regularly discussed survivorship care recommendations or provider responsibility with survivors; • Most (95%) oncologists who reported receiving detailed training about late and long-term effects of cancer provided survivors with written survivorship care plans and discussed survivorship care planning; and • Those primary care physicians receiving survivorship care plans from oncologists were nine times more likely to discuss survivorship issues with survivors.


The feasibility of using a capacitive sensor to sense the proximity of an external load, especially a finger, to a mobile terminal antenna was experimentally studied using a PIFA-type antenna as one of the sensor's electrodes. It was found that with the proposed arrangement it is possible to detect objects with permittivity close to that of body tissue or the conductivity level of aluminium and the size of a human finger at distances up to 15 mm.


We examined the characteristics of hepatocellular carcinoma patients with 10-year survival who had received initial treatment and been followed up for more than 10 years at our hospital. The 10-year survival rate was 12%, and comparison of patients who survived for 10 years (n = 36) and those who did not (n = 265) showed that the former had better hepatic functional reserve, with mild tumor progression and rates of usage of post-treatment interferon therapy and performance of hepatectomy. Comparison of patients with hepatectomy (n = 24) and those with percutaneous ablation therapy (n = 10) who survived for 10 years showed that those with hepatectomy had lower total bilirubin values, higher platelet counts, and larger tumor diameters. The total number of treatments in patients with tumor recurrence who survived for 10 years was 9.6 ± 5.2 in the case of hepatectomy and 14.6 ± 8.0 in the case of percutaneous ablation therapy. These findings suggest that repeated treatment can lead to long-term survival in patients with good hepatic functional reserve in whom initial treatment is radical and in whom subsequent periodic follow-up yields early detection of tumor recurrences.


Commentary A recent prior issue of Epilepsy Currents included two commentaries on studies of network activation in temporal and frontal lobe epilepsies and the association of network changes with cognitive deficits (1, 2). Both reviews emphasize the lack of evidence for the cause of the identified network abnormalities. The recent paper by Coan et al. from the Neuroimaging Laboratory at the State University of Campinas, Brazil, contributes further support that unique patterns of network dysfunction are associated with specific types of epilepsy. Additionally, their findings indicate that frequency of seizures and duration of temporal lobe epilepsy are associated with abnormalities in neuronal networks beyond the mesial temporal structures, which could have significant implications for the treatment and prevention of temporal lobe epilepsy. If recurrent seizures damage components of extended brain networks, perhaps stopping or reducing seizure frequency or severity by pharmacological or surgical interventions could prevent progressive dysfunction. The study by Coan and colleagues found volume loss in specific regions of extratemporal gray matter (GM) in patients with temporal lobe epilepsy. They present one of the largest published series, including 122 subjects with TLE and unilateral hippocampal sclerosis (TLE-HS), 50 with TLE and normal hippocampi TLE-NL), and 82 normal controls. Using established techniques of voxel based morphometry and statistical parametric mapping to analyze 3T MRI, they demonstrated that TLE-HS patients had severe volume loss of bilateral thalami and, bilateral pre-central and postcentral gyri, and ipsilateral temporal neocortex. Patients with TLE-NL had less severe GM volume loss but still had significantly smaller volumes in the bilateral thalami and pre-central and postcentral gyri, and the ipsilateral orbitofrontal cortex. It is noteworthy that patients with infrequent seizures and TLE-NL did not have significant GM loss in any regions. Patients with TLE-HS and frequent seizures had more severe volume loss than similar patients with infrequent seizures (e.g., see figure 1 from the article by Coan Frequent Seizures Are Associated with a Network of Gray Matter Atrophy in Temporal Lobe Epilepsy with or without Hippocampal Sclerosis.


Different numerical methods have been proposed for the solution of partial differential equations (PDE). Most of them are based on a variational principle which recasts the PDE into an equivalent integral equation. One of the most common principles is the Galerkin method, which has some specific disadvantages for some types of PDE. In this work an alternative variational principle, the least squares finite element method, will be tested with respect to its application for transient fluid-structure interaction problems. The accurracy of different formulations which were proposed for the Navier-Stokes equations in literature will be tested. In a next step these formulations will be coupled with a standard Galerkin approach for the structure. After that a new formulation for the linear equations of elastodynamics is developed and analysed with respect to its stability and accuracy. With this formulation it is possible do develop a pure least squares formulation for the strongly coupled fluid-structure problem. Finally the different formulations are tested with respect to their accuracy and efficiency.


ABSTRACT EVALUATION OF GRAPEVINE ROOTSTOCKS UNDER SUBTROPICAL CONDITIONS The work had as objective to evaluate the performance phytotechnical and disease tolerance ofrootstocks of grapevines in the formation phase the field, as well as the initial development of graftvariety "BRS Violeta". Seedlings originated from rooted cuttings of 17 rootstocks of grapevine ('SO4','Teleki 8B', 'Harmony', 'Golia', 'Riparia de Traviu', 'Paulsen', '420 A', '99R', '5C', 'RR101-14', 'Kober 5BB','Rupestris Du Lot', 'IAC 313 Tropical', 'IAC 766 Campinas', 'IAC 572 Jales', 'VR 043-43' and 'IAC 571-6Jundiai') were taken to the field at the end of spring in subtropical conditions. After four months, weevaluated the severity of anthracnose and rust of the grapevine on the leaves of the shoots of rootstocksand five months after the force of the same ones. The following winter, was performed cleft grafting thevariety 'BRS Violeta' and after 60 days was evaluated for percentage of sprouting, the diameter and theaverage length of the graft. The rootstock 'IAC 572 Jales' and 'IAC 313 Tropical' had presented lowerfoliar infection anthracnose and rust. The rootstock 'IAC 572 Jales' showed higher performance in thefield, prior to the operation of grafting, while the rootstock 'SO4', 'Harmony', 'Paulsen' and 'IAC 766Campinas' promoted more vigorously the development of graft 'BRS Violeta'.


This article discusses the worldwide demand for third language acquisition and fourth language acquisition. It reviews the current research on Language acquisition in relevant fields. Previous research is mainly about L2 learning, while this paper will fill the blank of L3 and L4 learning and compare the efficiency of learning L3 and L4 in different ways. By Control variates, we may find a more reasonable way for adults to learn new languages. There are experiments that the researchers let the Turkish-Persian bilinguals, Armenian-Persian bilinguals, and Persian monolinguals learn English, and compare their performance in vocabulary, or study Chinese students learning outcome of studying English and Russian. These experiments are all helpful and meaningful, but they only compare one aspect--vocabulary or writing, which is isolated and one-sided. This article compares students performance comprehensively, adopting standardized language tests to test students reading, listening, speaking and writing skills. But one major limitation of the study is that we dont exclude the gender impact. This will be the later future directions. This research shows that there is a need on acquiring multiple languages in todays globalized world, our researches should pay more attention on this field.


ONE EVENING IN 1991, my mother told my older brother that if he wanted to go out he had to take me with him. I was in the eighth grade, and my brother was a sophomore in high school. Our mother dropped us off at University of California, Riverside (UCR), and we went into a meeting for high school students hosted by the UCR Asian Pacific Student Programs (APSP). We all sat in a circle, Roland Coloma, who was the APSP Coordinator, asked us to introduce ourselves. Everyone represented Asian Student Clubs from different high schools from Riverside Unified School District (RUSD). The theme of the meeting was Filipino American history, and we watched a movie focused on Filipinos in Louisiana. I was captivated. My intuition told me that I was in the right place as a hunger to want to know and learn more about my history began. APSP, like many race-centered student programming prior to federal minority-serving funding, was created in 1989 from student protests and coalition building intended to create services for underserved students of color in higher education, including Asian American and Pacific Islander (AA&PI) students on campus. APSP coordinators, Vesi Save and April Veneracion, became mentors to me in high school and convinced me to attend UCR for college. Their involvement led me to be engaged in college as a student leader and encouraged me to utilize the services offered by APSP. Emilio Joe Virata, the Director at the time, taught me the meaning of being a leader with my peers. I am indebted to this program for the mentorship I received as it shaped me into a scholar, activist, organizer, and now professional conducting similar work with AA&PI students at San Francisco State University (SFSU). Interventions and services that center on race and ethnicity play a central role in college student development. I begin with this reflection as it highlights the long-term impact of culturally relevant programming for educational leaders of color, particularly Ethnic Studies. Throughout, I name my mentors in this narrative to pay homage to those who fought before and continue to fight for social justice alongside me. These relationships are paramount in guiding my leadership, mentorship, and teaching as I raise the next generation of scholar activists. In the following, I discuss how relationships are central in enacting an Ethnic Studies pedagogy in my role as a student affairs administrator charged with the development and implementation of AA&PI Student Services-Asian American and Pacific Islander Retention and Education (ASPIRE), the first Asian American Native American and Pacific Islander (AANAPISI) funded program at SFSU.


Abstract Growth in electronic devices comes with a challenge to engineers to provide proficient cooling mechanism in order to evade performance decline. Minichannel heat sinks are one among type of cooling devices to absorb heat formed in the electronic devices. Air is largely employed as cooling fluid in minichannels, but innovative methods are also adopted to enhance the heat transfer during the process. These days with modifications in the fluid flow passage and using liquid coolants such as nanofluids the Nusselt number is enhanced. These structural modifications adopted and different nanofluids employed with various volume concentrations and flow rates passed through minichannels to obtain enhancement in heat transfer rate are compiled in this article. The approach for these investigations is majorly categorized into numerical and experimental works. Numerical studies consisting of wide spread modeling methods like single phase/two phase flow modeling, laminar, transition/turbulent modeling etc. are reviewed. The related in-depth numerical and mathematical models used for computational analyses are detailed out exclusively. Experimental methods consisting of unusual passive techniques such as dimples/protrusions, pin fins, and corrugated channels. to achieve betterment in minichannel thermal performance are also provided. Another prime highlight of this article is compilation (in tabular form) of all the correlations and mathematical models used and developed to analyze different factors/properties during the thermal analyses. This article is concluded by providing an overall idea of different mathematical models and methods adopted in minichannels heat transfer analyses and future aspects to be addressed. Several important areas in minichannels heat transfer analyses exist which demand the optimization of heat and fluid flow processes and the use of machine learning concepts for analysis.


In an endeavor to tackle environmental problems, the photodegradation of microcystin-LR (MC-LR), one of the most common and toxic cyanotoxins, produced by the cyanobacteria blooms, was examined using nanostructured TiO2 photocatalysts (anatase, brookite, anatase–brookite, and C/N/S co-modified anatase–brookite) under UV-A, solar and visible light irradiation. The tailoring of TiO2 properties to hinder the electron–hole recombination and improve MC-LR adsorption on TiO2 surface was achieved by altering the preparation pH value. The highest photocatalytic efficiency was 97% and 99% with degradation rate of 0.002 mmol L−1 min−1 and 0.0007 mmol L−1 min−1 under UV and solar irradiation, respectively, using a bare TiO2 photocatalyst prepared at pH 10 with anatase to brookite ratio of ca. 1:2.5. However, the bare TiO2 samples were hardly active under visible light irradiation (25%) due to a large band gap. Upon UV, solar and vis irradiation, the complete MC-LR degradation (100%) was obtained in the presence of C/N/S co-modified TiO2 with a degradation rate constant of 0.26 min−1, 0.11 min−1 and 0.04 min−1, respectively. It was proposed that the remarkable activity of co-modified TiO2 might originate from its mixed-phase composition, mesoporous structure, and non-metal co-modification.


`̀Fortunately for practitioners in this department of the medical profession, a safe and effectual remedy for the unhappy disposition of maniacs here referred to, has been made known to the public through the practical work of Doctor Cox, who, though he generously gives credit of the invention to the late Doctor Darwin, was the first who had the courage to apply to practice the use of the CIRCULATING SWING, and which is now become of so much consequence in the cure of maniacs of almost every description.''

We consider building an indoor low-cost mobile robot that can be used in home or office applications. Due to the complication and dynamic changing nature of a home/office environment, it is essential for such a robot to be self-guiding in the sense that it is able to determine its current location as well as navigate to locations which it is commanded to. By integrating with wireless communication, indoor localization, and RFID technologies, it is possible to build a self-guiding robot at low cost. We propose an architecture to achieve this goal at centimeter-to-meter level accuracy. A robot can even roam into an area which is new to it. We achieve this goal by allowing a robot to download the indoor map in its vicinity. With WiFi localization, it determines its rough location at meter-level accuracy. From the downloaded map, it then tries to track any RFID tag in the indoor map, on which events it actually localizes itself at centimeter-level accuracy. To verify our results, we demonstrate a prototyping system based on iRobot. Our results have potentially important implications on future digital home/office.


Methods: Localized max echo sampled J PRESS was implemented on a 7T ClinScan MRI/MRS scanner equipped with a 72mm volume resonator for RF transmit in combination with 20mm surface receive coil. Prior knowledge 2D basis spectra generated using the GAMMA [4] included 19 metabolites: creatine (Cr), Nacetylaspartate (NAA), glycerylphosphocholine (GPC), phosphorylcholine (PCh), alanine (Ala), aspartate (Asp), γ-aminobutyric acid (GABA), glucose (Glc), glutamine (Gln), glutamate (Glu), glycine (Gly), glutathione (GSH), lactate (Lac), myo-inositol (mI), N-acetylaspartylglutamate (NAAG), phosphoethanolamine (PE), taurine (Tau), scyllo-inositol (Scy) and ascorbate (Asc). The method was validated in a phantom containing the same metabolites except Scy. The ProFit fitting of the J PRESS spectra was performed within MATLAB environment using a linear combination of the 2D basis spectra. For in vivo experiments, 7 male Fischer (strain: F344) rats, 3 fed with placebo diet (CE-2) and 4 with high fat diet (D12079B), were scanned when they were 13 weeks old using the following parameters: TR/minTE=4.0s/13ms, voxel size of 4x4x4 mm 3 (64μl), 16 averages, 50 t1 increments with 1024 points with an acquisition time of ~ 53 minutes. The body weight and blood chemistry was monitored once in every week. None of the rats were diabetic according to the insulin resistance tests.


Feofan Prokopovich's contemporaries believed that his catechetical works contained elements of Protestant
dogma. And in historiography it is commonly considered that Feofan's theological treatises became the
channel for the penetration of Protestant dogma into Russian religious thought. Similar accusations were
addressed to some Orthodox authors of the Polish-Lithuanian Commonwealth in the first half of the 17th
Century (Stefan Zizani and others), whose catechetical works received wide distribution in Russia and
determined the vector of development of the Russian catechetical tradition. This article analyses what specific
arguments were put forward by critics and from which theological position, and whether these accusations
testify to the actual presence of elements of Protestant dogma in the Orthodox literature of the era, or
whether we are dealing with a polemical argument.


"MGIMO – University" published the book "K.N. Leontiev. Notes and Reports" (preface by academician A.V. Torkunov, prof. K. Dolgov). Russian diplomatic documents of the second half of the 19th century from this book today also represent a significant historical and practical interest, as well as allow us to describe some of the methodological approaches to collection, analysis and presentation of information in the field of foreign and oriental perspective.


Obesity is strongly associated with cardiovascular diseases. Accumulating evidences have demonstrated a vital role of TLR4 signaling in the pathogenesis of obesity‐induced complications. Myeloid differentiation 2 (MD2), an obligate partner for TLR4, was required for LPS‐associated inflammation and TLR4 signaling activation. However, whether MD2 is also involved in the obesity‐associated inflammation is still unknown. The aim of this study is to investigate the involvement of MD2 in the pathogenesis of obesity‐induced cardiac diseases.


We give a method for constructing certain orthogonal matrices of arbitrary dimension. As application, we construct orthonormal piecewise constant wavelet bases on two-dimensional domains.


SST is arguably the most visible climate variable in the public forum of climate change debate. In climate change detection and attribution studies they are usually used in the form of gridded data sets which are analyzed statistically or serve as boundary conditions for atmospheric general circulation models. Therefore it is of primary importance to ensure their optimality and reliability, especially for the pre-satellite data period, including reliability of their error estimates. Most current methods of gridding blend together satellite and in situ data and involve a mixture of optimal interpolation (successive corrections), eigenvector reconstruction, bias correction techniques, and some forms of data assimilation [Reynolds and Smith, 1994; Rayner et al., 2003; Kaplan et al., 1997,2003]. Analyses of the pre-satellite period depend on quite sparse in situ data as their inputs, but they usually try to make use of statistical information extracted from the satellite period [Smith et al., 1996,1998; Rayner et al., 2003; Kaplan et al., 2003]. Therefore, the quality of these analyses and hence our ability to detect and properly attribute long-term climate change hinges on the quality of a priori statistical information obtained from the satellite data. The goal of this project is to make use of the extensive satellite data in order to quantify and model in situ data errors, and thus to improve pre-satellite era climate analyses. To this end we present intercomparisons of MODIS SST products, and their comparisons with Pathfinder V5 SST and the in situ data collection ICOADS. Further, we estimate small-scale and short-term variability of SST using satellite data sets. We then successfully use these estimates to model the magnitude of the the error in the binned in situ SST values.


It is well established that some bacteria can suppress plant diseases through the expression of multiple mechanisms, including the direct inhibition of plant pathogens and the indirect induction of plant host resistance pathways (Kim et al., 2011). Because of this, microbes that form close associations with plants are the primary source of active ingredients in biopesticides for the control of plant diseases. But for over a decade now, molecular techniques have provided a glimpse of the diversity of soiland plant-associated microbes and the factors controlling their diversity and plant disease suppressing activities.


Supervision of teaching practice is an important aspect of training teachers in improving their teaching skills. Barriers such as distance and time factor are the constraints faced by the lecturers at the National University of Malaysia to communicate with the teacher trainees under their supervision. Therefore, this study aims to develop and evaluate a social-networking site Ning's platform for the supervision of lecturers to teach on-line training. This study used the case design where a total of nine teacher trainees involved in this study. It found that overall, acceptance of the use of the social-networking site Ning mean score at the highest level of 3.91. In addition, all student teachers have positive attitudes towards the use of the social-networking site Ning social-networking site and agree a suitable approach to the supervision of one of the online teaching practices. While the "blog" is the most active facility used by student teachers in which they do self-reflection. In conclusion, the social-networking site Ning has the potential to assist lecturers to carry out supervision on-line teaching practice.

A series of syndiotatic P5CPn polymethylenes was prepared with 4-(trans-4-pentylcyclohexyl)phenoxy moieties linked to each backbone carbon atom via an alkyloxycarbonyl spacer and with even numbers of alkyl carbons n ranging from 2 to 14, and their thermotropic behaviors were investigated. The P5CPn, except P5CP2, formed smectic phases in which the rod-like polymethylene backbones were arranged in rectangular lattices, and the side-chain mesogens were aggregated into layers parallel to the shorter sides of the rectangular lattices. The packing of the mesogens changed with decreasing temperature from smectic C-like to smectic I-like (SmI-like) for n = 4–8 and from smectic A-like to SmI-like for n = 10–14. In the SmI-like phases, each mesogen along the main-chain axis was connected to every sixth backbone carbon atom, revealing a correlation between the packing of the mesogens and the main-chain conformation of a 3/2 helix. Conversely, P5CP2 formed a smectic phase with the main chains arranged in rows and wi...

Electric fields applied along the b axis of deuterated betaine calcium chloride dihydrate induce four main effects. The commensurate phases δ=2/7 and 2/9 are more clearly revealed than in zero field, the extension of the latter increasing from 0.6 to 5 K between E=0 and E=4 kV/cm. The commensurate phase with δ=2/11 is stabilized in an interval of 1 K. An additional phase appears at E=2 kV/cm, between the phases 1/5 and 2/9. Finally, indications of the stabilization of the 4/15 phase are obtained

Thinking aloud is a methodology that is frequently employed in language study to gain insight into test participants cognitive processes. It can provide a rich source of data that illuminates what's going on in the person's head during the performance of a task. Being a delicate and effective methodology, thinking aloud must be designed and handled with care to ensure its validity.


In the coming years, there will be a transformation of learning systems around the globe, which will be aided by new technologies and information science. With the advent of artificial intelligence and mobile devices with cutting-edge capabilities, the learning process will undergo the most significant changes in over a century. The use of mobile learning methods is becoming increasingly popular as new technology advances. According to the authors' literature review, as the field of research advances, more and more researchers are investigating the effects of artificial intelligence on learning, teaching methods, and teacher evaluations. The paper also discusses the benefits of using artificial intelligence to facilitate independent learning. Rather than being seen as an adjunct to learning and teaching, Artificial Intelligence helps to enable a fundamental shift in thinking about what should be taught and how it should be taught. It is both an exciting opportunity and a serious responsibility for a company that are of big size. Toward meeting this challenge, this article examines several key precursors and determinants of learning and artificial intelligence. Recently, a number of terms have been introduced into the field of learning, including portal connectivity, artificial intelligence, big data, machine learning, mobile technologies, and intelligent learning patterns. Due to these changes, society and education have undergone unprecedented transformations. The authors of the study conclude that the use of artificial intelligence in learning is likely to follow the trend that shows a rapid increase after a period of relative stability. As artificial intelligence develops rapidly in the field of learning, the way knowledge is conveyed and the ability to learn new things will be greatly altered.


Ride sharing systems enable people with similar itineraries and pick-up times to share their rides on the same vehicle. This has significant societal benefits as it reduces the number of vehicles used and hence reduces energy consumption and emissions to the environment. However, current systems do not fully address the potential of ride sharing as they do not utilize the transportation network effectively. A change in the ride assignment/scheduling algorithm to batch multiple requests has proven to be effective when extended time utilization is considered. Current batching based assignment methods generate all possible combinations of the trips for a given set of requests and vehicles, and then solve the assignment problem using integer linear programming (ILP). This becomes more computationally expensive as the combinatorial search space grows. In this paper, we propose overcoming this scalability problem by learning the reverse nearest neighbors order for a given location using pointer networks to effectively reduce the number of candidate trips considered in ILP. With extensive experimentation using real data, we show that our proposed solution, termed Learn2Pool, offers the most practical solution for ride assignment by allowing striking a balance between efficacy and efficiency, while demonstrating superior efficiency and efficacy across all existing methods.


London-based company ScanLab Projects is a multi-disciplinary commercial collaboration between architect, artist, coders and designers who utilize technologies surrounding 3D laser scanning in their practice. Inherent in the manner their projects are pitched is through reference to
 the photographic as technological process. Central to their engagement with the light detection and ranging (LiDAR) scanning apparatus is a consideration of the relationality between virtual or digital object and what could be determined as extrinsic or 'real' terrain. In Post-lenticular
 Landscapes, 2017, ScanLab created a series of LiDAR scans of Yosemite National Park. The landscape, presented as a stereoscopic film work where the spectator flies through an ephemeral black and white point cloud, is contextualized relationally to a certain photo-historical context and
 lineage: As Yosemite is synonymous with the advent of photographic process through the work of Muybridge, Watkins, Woods and Adams, the work revisits an archetypal image of the American sublime. In this text, I unpack ScanLab's usage and conceptualization of LiDAR scans referentially
 to an understanding of the photographic. By considering how ScanLab frames our understanding of the project through the technological apparatus, the text attempts to problematize the scans by reading them through a particular art historic heritage. In this context, I posit alternate ways of
 reading the work, specifically through reference to the image of Yosemite that has proliferated across the desktops of Apple computers since 2014. Furthermore, through a reading of metonymy in the writing of Eelco Runia, the eerie as understood by Mark Fisher and in relation
 to Lev Manovich's description of photorealism, I propose that the future of the mediation and understandings of machinic vision are to be thought with a reconsidered notion of the photographic.


The basic concept of a combustion motor is to convert chemical energy into heat energy and then convert it to mechanical energy. Heat energy is produced from the combustion process between a mixture of fuel and air with a pressure difference triggered by  spark (flame). The objective is to determine the difference in power, torque, and average effective pressure by adding the number of spark plugs and using the standard type of spark plug and iridium on a single-cylinder engine. The engine performance testing method uses P-max to get power, while the analysis uses experimental design, the data processing method uses DOE-factorial and the Minitab application 18. Power test for a standard spark plug resulted in 7.93 HP, 0.89 kgm torque and 1207.66 kPa average effective pressure. For iridium spark plug the test produced 9.02 HP, it is  0.91 kg.m for torque and average effective pressure is 1226.32 Kpa. For two standard spark plugs, the power was 9.38 HP, torque was 0.93 kg.m, and the average effective pressure was 1269.96 kPa. Whereas the two iridium spark plugs produced 9.59 HP, 0.91 kg.m torque, and  1277.78  kPa average effective pressure.


A new species of seahorse, Hippocampus colemani, is described from Lord Howe Island off eastern Australia. It can be distinguished from congeners by the following combined features: very small size (to about 23 mm in height), very deep trunk (about 60% in its length), low number of tail rings (27-29) and most distinctly, a single gill opening, placed dorsally behind the head.


In the present study two simple, accurate, economic and repeatable derivative spectrophotometric methods were proposed for the determination of ofloxacin in bulk drug and in pharmaceutical form. Quantitative determination was carried out using second order derivative values measured at 289 nm and third order derivative values measured at 295 nm. Calibration graphs prepared at their wavelengths of determination were linear in the concentration range of ofloxacin using 2-30 μg/ml and 5-35 μg/ml for second and third order derivative spectrophotometric methods. The correlation in two methods is 0.998 with regression equation of Y=0.00045x-0.00017 and Y= 0.000072x-0.00003, where Y denotes amplitude of peak and x is the concentration of sample in μg/ml. The proposed methods have been extensively validated as per ICH guidelines. The developed spectrophotometric methods in this study are specific, sensitive, reproducible, precise, and can be routinely utilized for the analysis of pharmaceutical formulations.


The term used in the title has been coined by analogy with folie a troix. "Instead of disputing the facts, we must try to explain them. But whatever explanation we offer, we soon find ourselves in very deep waters indeed." —H. H.Price 19 Introduction It has long been known that "true," or "ordinary," hallucinations are very common not only in certain psychoses but also in various toxic conditions, infections, etc,; yet only recently has it become clear that some parahallucinatory phenomena, in particular those connected with sleep (e. g., hypnagogic and hypnopompic imagery) also occur oftener than it was generally realized. Many contemporary authors (Ardis and McKellar, 2 McKellar, 15 McKellar and Simpson, 16 and others) express this view. For instance, Smythies 22,23 writes: "Visual hallucinations in the form of hypnagogic and eidetic imagery, occur . . . frequently in normal people." Similarly, Dawson 5 states: "Hallucinations occur in


A pandemic began to occur in Nisibis in AD 165 during the Parthian expedition, which began in AD 162 under the command of Lucius Verus. Military troops which had their headquarters stationed in the Balkans and in the European regions of the empire, were involved in the Parthian expedition and suffered under this pandemic. The epidemic then moved further into Europe and even to Britannia, as the soldiers who had participated in the expedition from AD 162 to AD 166 later returned to their headquarters at the borders of the Rhine and Danube. The losses which occurred as a result of the epidemic in the period of Marcus Aurelius were not exaggerated. The death toll was very high and the population structure within the borders of the empire was significantly affected. The destruction caused by the disease continued for years, as stated in the sources of the period. According to these sources, the disease even spread to the Barbaricum region outside the borders of Rome and also continued during the period of Commodus who reigned immediately after his father Marcus Aurelius. Neither the epidemic which had occurred in 430-429 BC in the vicinity of Athens, nor that of AD 248 in Rome (also called Decius or Kyprianos), spread to such a vast area as the pandemic of AD 165, and the death toll of these other epidemics was not as high as that of AD 165. By comparison, the Plague of Justinianus in the 6th century spread in waves and caused many deaths for years. Like the plagues of the medieval period it changed the populational structure of the world. In the 19th century ancient historians argued that the destructive effect of the pandemic of Marcus Aurelius' era, also known as "The Antoninus Epidemic", caused the political, military and economic crisis that the Roman Empire faced in the 3rd century and it could even be interpreted as the end of Antiquity. However, there were other reasons for this crisis in the 3rd century, and it is notable that the negative effects of the pandemic were mainly seen in the second half of the 2nd century.


Citizenship has been in the last thirty years a significant concern of anthropologists, not least because it has been in the same period a concern of people around the world. At least, the term "citizenship" has been used widely, if not always in quite the same way as anthropologists have used it, especially those anthropologists who have paid less attention to their informants' understandings of it. During fieldwork in west Mexico in 2007–2010, I found that my informants did not reduce being a citizen to having a relationship with the state or government. Many of them said that being a citizen was ultimately about "living in society". Their use of the term "citizen" reminds us that many different things have been called "citizenship" over the centuries, and that some things now called "citizenship", such as claiming rights on states, have not always been referred to as such. However, I prefer to focus on the concepts that my informants sometimes labeled "citizenship" rather than on their choice of the word itself, and to be more precise I use the term civil sociality to gloss their sense of living in society, ideally in a civil way. I focus on how civil sociality stands in relation to law as well as to rights-bearing, especially in two sets of events in which people pitched their claims in terms of both civil sociality and law. Throughout, I draw out the methodological, historical, ethnographic, theoretical, and normative implications of the way in which my informants juxtapose civil sociality and law or rights-bearing. I end the article by comparing my informants' notions with those of anthropologists, noting not just the differences but a striking similarity. Anthropologists, like my informants, treat "society" as a ground that lies beyond institutions such as law.


To clarify the proper nitrogen application level for rasing rice infant seedling under different nursery soil, Dongjinbyeo was raised at seedling box with different basal nitrogen level. The results are as follows. The higher the nitrogen level was, the lower emergence rate and the lower establishment rate. The establishment rate was less than 90%, when the nitrogen was more than 2g/box in hill soil and more than 1g/box in paddy soil. The more the nitrogen level was, the higher the seedling height in hill soil, but was higher in the order of N-2, 3, 1 and 0g /box. Leaf number wasn't significantly different between nusery soils and among nitrogen levels when seedling was raised more than 6 days. The endosperm survival rate was decreased as the increased nitrogen level, but wasn't different between the nursery soils. Amount of root was decreased as the increased nitrogen level in paddy soil, but was heavier in the order of N-1, 0, 2 and 3g /box in hill soil. Mat formation was better as the nitrogen level was decreased in all nursery soils. Considering the emergence rate, seedling charactors and mat formation, the proper nitrogen levels seemed to be 2g /box for hill soil and 1g /box for paddy soil.


Compared with conventional pumped-storage hydroplants, seawater pumped-storage hydroplants are constructed in a complex marine environment. The wave disturbance may affect the safety operation of the pump turbine in the seawater pumped hydroplant via affecting the level of the free water surface. To explore the effect of wave disturbance on the operation of the pump turbine in a seawater pumped-storage hydroplant, assuming that the wave disturbance follows a sine function, on the basis of Airy's micro-amplitude wave theory and the comprehensive characteristic curve of a pump turbine, we use sliding grid technology and the SST k–ω turbulence model to simulate the dynamics of fluid in a full-flow channel. In this study, the unsteady flow field, Q-criterion vorticity, relative pressure pulsation amplitude, and frequency of pressure pulsation are analyzed to determine the internal flow field and pressure pulsation under different wave disturbance conditions and operating loads. The results show that both the pressure pulsation in the pump turbine and its frequency domain are affected by the wave disturbance. In addition, the turbulent flow with a large flow rate tends to produce higher relative pressure pulsation under wave disturbance. Due to the large flow rate and strong static and dynamic interference in the vaneless area, the relative amplitude of the pressure pulsation is significantly affected by wave disturbance. Furthermore, the low-frequency pressure pulsation of the draft tube is superimposed with the wave disturbance frequency.

In this quarter we studied the effect of hydrogen pressure, and of sulfur and nitrogen containing compounds on the isomerization and hydrocracking of n-hexadecane using a Pt/ZrO{sub 2}/SO{sub 4} catalyst. The reactions were carried out at 300{degrees}C and hydrogen pressures between 50 and 500 psig. Increasing hydrogen pressure resulted in increased conversion and increased hydrocracking. Nitrogen containing compounds had a greater inhibiting effect on the conversion of n-hexadecane than sulfur-containing compounds. The reaction of diphenylmethane in air at 25{degrees}C and in the presence of sulfated zirconia was studied as a possible means to characterize the protonic acidity of solid superacids.


Recently a variety of array detectors have been used in the focal plane of Czerny-Turner plane-grating spectrometers. The output signals have been coupled to a variety of storage units, resulting in optical multichannel analyzers (OMA). We present a clarification of the method for calculating the dispersion of this instrument, as well as a table of useful spectroscopic parameters for spectrometer-detector array combinations.


This PhD thesis states its aim very straightforwardly: to explore the relationship between the conquest of New Spain and the booty that the Spanish adventurers hoped to take. Although it is common knowledge that the spoils of war provided one of the central motivations for Spaniards to take the risk of entering a dangerous and unknown foreign country, how exactly the "political economy of conquest"—the interaction of political and economic interests in the conquest—worked is still largely unknown. Huber states correctly that even the abundant literature of the last decades has not added much to our knowledge in this regard.


Aiming to improve the industrial and mine sewage treatment by using immobilized Lentinus edodes, a kind of cheap biosor-bent, this paper is focused on the study of the desorption process of Pb~(2+) and Cd~(2+) by immobilized Lentinus edodes , so as to find a method for recycling heavy metals. In proceeding with our study, we have first of all investigated such important parameters, as the sort of desorbent, equilibrium time and the concentration of the desorbent. The experimental results from our research indicate that among the six desorbents(H_2SO_4, HNO_3, HCl, Na_2CO_3, NaHCO_3, NH_4Cl), HCl and HNO_3 could desorb more Pb~(2+) and Cd~(2+) from the immobilized Lentinus edodes than the other four, with the effect of HCl being better for the desorption behavior. Desorbing Pb~(2+) and Cd~(2+) with HCl, the equilibrium time was 90 min and 60 min respectively. With the pseudo-second-order model well fitted for Pb~(2+) and Cd~(2+) desorption data, and the correlation coefficient—0.996 9 and 0.998 9, respectively , the desorption ratio of Pb~(2+) tends to reach its maximum limit of 99.01% when the concentration of HCl is 1 mol·L~(-1), while that of Cd~(2+) reaches its maximum limit of 80.81% at the concentration of HCl being 0.1 mol·L~(-1). According to the scanning electronic microscope and the energy spectrum observation, the surface of polyvinyl alcohol-Na-alginate (PVA-SA) immobilized Lentinus edodes beads is rough and porous before the absorption. By the physical adsorption or/and forming inorganic sediment, heavy metals were adsorbed on the cell walls of immobilized beads after adsorption. In addition, the Pb~(2+) and Cd~(2+) crystal was found on PVA-SA immobilized Lentinus edodes after absorption. And the surface of PVA-SA immobilized beads would become close-grained. But after desorption with HCl, the surface of the beads would return to be rough and porous again. Then the recycled beads could be used for absorbing heavy metals again. Thus Pb~(2+) and Cd~(2+) biosorption ratios for PVA-SA immobilized Lentinus edodes could still reach 85.24% and 69.07% respectively after the three times of regeneration.


The design of experiments is a highly effective offline quality improvement method to optimize the existing and new processes or products. In the literature, standard experimental situations have been paid a lot of attention. In a number of nonstandard experimental situations, special experimental design techniques should be considered in order to conduct an experiment for design factors. Indeed, an I-optimal design, a computer-generated special experimental design, is a good choice to predict the mean and variance responses under non-standard experimental design situations. In this research work, an I-optimal design is selected to generate experimental design points for a non-standard experimental situation. Then, an I-optimal design-based dual response optimization model is proposed in order to obtain an optimum operating condition for design factors while minimizing the process variance as small as possible. Comparison studies are also conducted. Finally, a numerical example is conducted in order to illustrate the effectiveness of the proposed optimization model.

Abstract We have studied the crystallization process in the Bi-Pb-Sr-Ca-Cu-O system from an amorphous state, and we have characterized the superconducting properties of thick film samples prepared on MgO substrates by annealing. A rapidly quenched sample showed amorphous nature. After this sample was annealed at 500°C, Bi2Sr2CuO x phase was found. At 650°C, the Bi2Sr2CaCu2O y phase appeared. The sample at 800°C consisted of the Bi2Sr2CaCu2O y phase, while the Bi2Sr2Ca2Cu3O z phase occurred at 850°C. Thick film samples were prepared by annealing at 855°C, the partial melting temperature, for 1-400 h. A short-time annealed sample showed semiconducting behavior in the normal conducting state, but longer annealing showed the more remarkable metal-superconducting transition. This was considered to be due to oxygen deficiency and weak coupling at grain boundaries. The highest Tc(0) is 91 K in a sample annealed for 400 h., although it consisted of high-Tc and low-Tc mixed phases.


Introduction: There is limited specialist facility and lack of data on gallstone and laparoscopic cholecystectomy (LC) in children locally and in the region. With one government children hospital in Nepal, specialist service is far from adequate. Utilizing existing facilities to provide service is the need. We analyzed 14 years data to look in to the safety of LC in children provided by general surgeons in a general teaching hospital with conventional LC instruments used for adults.


An area located at Calaveras Dam, Alameda County, California, previously determined to be heavily populated with ground squirrels [Citellus beecheyi (Richardson)], was selected for field study of (1) the correlation between flea populations existing at squirrel burrow openings and of flea populations on the rodent hosts, and of (2) the seasonal species composition of these populations. One portion of this area was set aside for the study of the fleas at the openings of the burrows, and a contiguous and ecologically similar portion was utilized for the study of fleas taken directly from their hosts. Fleas at the burrow openings were collected from pieces of cotton batting placed in each burrow mouth. Thirty burrows were set aside for these studies, divided into 3 groups of 10 burrows each and approximately equally distributed as to direction of exposure, amount of exposure, surrounding cover crop and topography. Collections were made at approximately weekly intervals from April 29, 1940, to October 23, 1940, as shown in Graph 1, and they were made in regular rotation among the 3 sets of burrows in order not to influence unduly the population densities by repeated collections. In the same period and also at approximately weekly intervals, as shown in Graph 2, ground squirrels were trapped alive, lightly anesthetized with chloroform, and thoroughly combed to remove all fleas. At each burrow collection temperatures were taken at points 1 foot within the mouth of the burrow and 6 feet above the ground. All fleas collected were mounted and identified; of approximately 7500 fleas collected only about a dozen belonged to species other than Diamanus montanus (Baker) or Hoplopsyllus anomalous (Baker). As shown in Graphs 1 and 2, Diamanus montanus was markedly-predominant in the flea population from April 29 to June 28 and Hoplopsyllus anomalus was markedly predominant from July 11 to October 14. No correlation could be detected between either atmospheric or burrow temperatures and flea indices other than that Diamanus montanus was predominant while the mean temperature was below 75°F and Hoplopsyllus anomalus was predominant while the mean temperature was above 75°F.


Application-Specific Standard Products (ASSPs) have been so far customized by an increasing amount of embedded software or very recently by electrically and mask-programmable embedded gate-arrays. The solution proposed in this paper addresses both the large demand for higher flexibility and the need for fast product turnaround time. This is achieved by using single-via programmable logic and consistent hardware and software co-design flow. The system architecture is discussed as well as the design flows for pre-and post-silicon design and customization. The silicon area required by the system is 23mm2 in a 0.13pm CMOS technology. The embedded via-programmable logic accounts for about 30% of the system area. Introduction Programmable platfom are object of increasing attention as a viable solution for the ever increasing need of configurability and flexibility at the device level to support continuously changing and evolving system applications requirements. Application-Specific Standard Products (ASSPs) commonly


Aircraft structures are very susceptible to impact from foreign objects such as debris, ice crystals from rain or attacks from animals. This incident has a serious impact and poses a threat to the safety of civilian aircraft operations and can lead to disasters such as plane crashes. Currently, Unmanned Aircraft Vehicle (UAV) is developing very rapidly. Horizontal stabilizer is a very important part or component on an airplane. The horizontal stabilizer structure of the aircraft with a passenger of 189 people must be able to withstand the attacks of birds with a mass of 8 lb or about 3600 gr. The purpose of this thesis is to determine the dynamic response of the horizontal stabilizer based on variations in the collision parameters of the drone. This simulation is performed using finite element software or CAE Abaqus. This simulation is carried out by prefixing a drone collision simulation on the horizontal stabilizer section and will be compared to the bird simulation being hit on the horizontal stabilizer section. Drone collision at the location between the ribs in section 2 with an angle of 0o at a relative speed of 151 m/s horizontal stabilizer suffered serious damage. Drone collisions with a smaller mass compared to the horizontal stabilizer are more seriously damaged than bird strikes, because the drones damage the ribs, spars and skins on the horizontal stabilizer.

What kind of society is most profitable to govern—one that is internally fractionalized or one that is not? Conventional wisdom and the logic of collective action suggest that a predatory state may benefit from fractionalization, as internal conflict distracts the population from collective resistance against expropriation. Using a formal model, I show that the profits of social division depend critically on the state's revenue base. Internal conflict does not just reduce subjects' incentive to resist, but also to engage in economically productive activity. All else equal, a state that taxes the products of the society's labor benefits from a unified population. Conversely, a state whose objective is to control a fixed stock of wealth, such as natural resources, benefits from internal divisions. The incentive for a colonial empire, military occupier, or burgeoning state to extend its authority over a fractionalized population therefore depends critically on economic factors. ∗This paper is based on my dissertation chapter "Dividing the Conquered."

The object of a predatory state, whether a colonial empire or a kleptocratic dictatorship, is to profit from power. Collective resistance by the subject population against a predatory regime or its extractive policies threatens the profitability of rule. Consequently, political practitioners—like the Roman empire and, later, Machiavelli—have sought to understand how governments can exploit mutual hostilities or fears between factions of their subjects to discourage collective action among them. More recently, scholars in political science, political economy, and history have studied the strategies by which rulers manipulate social divisions in order to maintain their positions and preserve their access to rents (e.g., Acemoglu, Verdier and Robinson 2004; Padró i Miquel 2007; Debs 2007; Burbank and Cooper 2010). In this paper, rather than analyze specific strategies of divide-and-rule politics, I seek to establish a simple theoretical baseline about the relationship between social fractionalization and predatory governance. What kind of society is most profitable to govern—one that is internally fractionalized or one that is not? International relations scholars study interactions in which the boundaries of authority may shift and the shape of the society governed by the state is at least in part a matter of choice. To answer questions like the following, it is important to have a baseline understanding of how social fractionalization affects the profitability of rule. How did ethnic distinctions among colonized populations affect imperial competition and the timing of decolonization (Michalopoulos and Papaioannou 2013, 2016)? How do internal schisms within separatist movements affect central states' willingness to fight to preserve control (Cunningham 2011; Lacina 2015)? How does the success and profitability of a military occupation depend on the social relations of the occupied population (Liberman 1993; Edelstein 2004)? More broadly, which boundaries between peoples are politically sustainable (Carter and Goemans 2011)? What kinds of populations are attractive targets for conquest? I model the political economy of predatory governance in a fractionalized society, identifying an economic variable—namely, the source from which government revenues derive—as the key determinant of whether the profitability of rule increases or decreases with the ex-


Despite the pervasive role of science in modern civilization, it is not regarded as an integral part of our general culture. The scientific illiteracy lamented more than 30 years ago by C P Snow now seems to be even more prevalent and ominous. It prevents people from reaching an informed consensus in many current political debates, such as that over "star wars". Another striking instance of the cultural gulf in the US is the recently proposed national standards for teaching American history. From a process extending over three years and involving many historians, a 250-page document emerged, setting out a new curriculum for school children of ages between 10 and 17. It makes no mention of any scientific discovery or of any scientist.


Scanning electron microscope (SEM) was used as a powerful tool to analyze the morphology of ZnTe crystals grown from Te solution. ZnTe crystals found on the end of ZnTe ingot are with micron- to submilimeter size, and their shapes can generally be classified into polyhedral type with smooth facets, and skeletal type with concave faces. The morphology formation mechanisms were discussed. It was found, the ZnTe crystal shape and surface morphology is very sensitive to the growth condition. In spite of the thermodynamics factor (Gibbs free energy theory), the kinetic factors, such as the crystal size and crystalline driving force, play more essential roles in the control of the shape of ZnTe crystals.


The selection of a centrifugal system for chilling water and its optimum location have been carried out in the present case study based on (a) energy conservation, (b) economy and (c) operation and maintenance. The, comparison is done between the R-11 open and R-12 hermetic centrifugal water chillers (eWes). Thermodynamic analysis for 400 ton renders the capacity of the former to be 8 ton higher than that of the latter. The former is also found to be better than the latter for air-conditioning and inferior to the latter for heat pump use. Moreover, for the year round air-conditioning the hermetic unit stands a better position. The evaluation of various quantities based on the location of the central ewes shows an additional expenditure of Rs. 1. 4 million for the plant of Rs. 13.6 million due to (a) 79 kW of loss of refrigeration· by heat transfer, (b) 16 kW of refrigeration loss due to more pumping energy, (c) 16 kW of increased pumping power and increased cost of larger size pumps and (d) losses of power and more maintenance cost. Further, the use of ozone friendly and proven refrigerants like R-717 and R-718 is stressed.


With the fast growing of artificial intelligence (AI), more and more applications require querying uncertain data, especially from social media and crowd sourcing platform. In situations where it is impossible to increase data quality by controlling the sources, we may resort to algorithms to make the best use of the collected data. Since crowdsourcing provides a useful way to distributing tasks to mass people, and collects labels from as many workers as possible, many researchers have been study crowd source inference algorithms. In our work, we propose a novel crowd-sourcing inference algorithm to infer ground truth and obtain worker reliability and task difficulty at the same time. Keywords—Truth Inference; Crowdsourcing; Message Passing.


Topics chosen from first-year calculus illustrate a number of "sayings" or "proverbs," the first three, for example, being: be awed, like a child; meaning before truth; and act with intention. Many are proverbs for life as well as mathematics.


Describing orally what we are seeing is a simple task we do in our daily life. However, in the natural language processing field, this simple task needs to be bridged by a textual modality that helps the system to generalize various objects in the image and various pronunciations in speech utterances. In this study, we propose an end-to-end Image2Speech system that does not need any textual information in its training. We use a vector-quantized variational autoencoder (VQ-VAE) model to learn the discrete representation of a speech caption in an unsupervised manner, where discrete labels are used by an image-captioning model. This self-supervised speech representation enables the Image2Speech model to be trained with the minimum amount of paired image-speech data while still maintaining the quality of the speech caption. Our experimental results with a multi-speaker natural speech dataset demonstrate our proposed text-free Image2Speech system's performance close to the one with textual information. Furthermore, our approach also successfully outperforms the most recent existing frameworks with phoneme-based and grounding-based Image2Speech systems.


Develop a monitoring and management system based on a cloud platform, and finally implement related applications such as abnormal monitoring of the electric energy meter wiring process, wiring fault diagnosis, line aging assessment, and power outage warning analysis on the cloud platform, which can promptly warn the occurrence of power outages and comprehensively improve high-quality power supply services Level. Therefore, this paper proposes a method for phase line and neutral line impedance estimation of 0.4kV low voltage distribution network based on intelligent electricity meters. In this paper, the voltage of each sequence, current of each sequence, and information of complex power of each sequence of each node are extracted by intelligent electricity meter, and then the measurement of line impedance is completed piecewise. Finally, the impedance measurement model of the 0.4kV low-voltage distribution network was built. The simulation verification of the line impedance measurement was completed through the effective cooperation with the high-precision and high-synchronous sampling smart electricity meter supporting the impedance measurement and the acquisition terminal supporting the of the impedance measurement. The simulation results show that the line impedance measurement error is small, and the prediction of line loss and impedance trend can be completed effectively.


We present an experimental study of the infrared absorption spectra of solid, enriched ortho-hydrogen and para-deuterium in the ordered state for concentrations x of J = 1 molecules between O. 65 and O. 98 and temperatures from 0.9 to 11 K. Comparison is made to theoretical expressions and numerical results for the absorption due to various microscopic processes, involving phonons and combinations of librons and phonons, which couple to the dipole moment induced by the electric quadrupole (EQ) fields of J = I molecules. The concentration dependence of the sharp, low-frequency optical phonon has also been studied. The integrated intensity of this feature is found to be quadratic in x and the frequency is well described by to(x)= a + b x e, which is the expected behavior for shifts arising from pairwise E QQ interactions. For constant x, the temperature dependence of the intensity of this phonon scales with the square of the long-range orientational order parameter. Our measurements of this quantity are compared to NMR determinations of the temperature dependence of the Pake splitting in the ordered state.


In Content Based Image Retrieval (CBIR), there is semantic gap between the low level features and high level concepts. Advent of different relevance feedback techniques bridges the gap. Different techniques use different assumption. Yet there are some performance metrics which quantitatively measure and compare different relevance feedback algorithms. This is necessary to make the CBIR system work consistently. In this paper we analyze different relevance feedback algorithm starting from conventional to recent technique.


ABSTRACT A large collection of old membrane filters from the American cruises of the R/V Vema and R/V Robert D. Conrad has been recently curated and provides a unique opportunity to study microplankton distribution in the 1960s. Filters from the subarctic Pacific Ocean and Bering Sea collected in May–July 1964 and June–Aug 1966 were observed in detail for the first time using scanning electron microscopy, to investigate assemblages of Parmales (Bolidophyceae). These filters were dominated by Triparma columacea f. convexa and T. strigata, with maximum absolute abundances of total Parmales up to 11.0 × 103 cells ml−1 and average abundances often one or two orders of magnitude higher than those of more modern studies. In later studies, Tetraparma pelagica is often cited as the dominant taxon, but it was less important in the 1960s. Since temperature is an important factor in controlling Parmales growth, this shift from high to low absolute abundance, and from the dominance of T. columacea f. convexa/T. strigata to Te. pelagica, could be related to a major climate shift in the late 1970s, and to the dramatic decrease in sea-ice cover and changes in plankton composition in the subarctic Pacific Ocean and Bering Sea.


The overall objective of the study was to determine Nigerian university students' awareness and exposure to label warnings on portable electric power generators; their level of comprehension of these label warnings; knowledge of carbon monoxide poisoning; and, preventive measures taken to avoid carbon monoxide poisoning. The survey research method was used for this study. Data was collected in Southeastern Nigeria among undergraduate students, by administering questionnaire to a sample of 400 students from four universities. The study found a high level of exposure to label warnings on house hold products but a minimal exposure to label warnings on portable electric power generating sets among these students.Variables like placement of the warnings, font sizes and religious inclination hindered exposure to the warnings and compliance to the warning message; awareness of carbon monoxide information was high and a greater number among the respondents got informed either through their families and friends or read about it; a relatively lower number got informed through the media. While these university students were aware of carbon monoxide poisoning, they were not properly informed of the different symptoms that are associated with the gas and the preventive measures that could prevent carbon monoxide poisoning. This suggests that carbon monoxide poisoning is not being taken seriously as a health hazard among people susceptible to poisoning.

This study set out to examine the association between prayer frequency, purpose in life and attitude toward substances, among a sample of 2,563 13- to 15-year-old secondary school pupils in England and Wales. Multivariate models controlling for sex, school year and personality (as defined by the Eysenkian dimensional model) demonstrated that higher levels of purpose in life are associated with greater prayer frequency, and that more proscriptive attitudes toward substances are associated with both higher levels of purpose in life and greater prayer frequency. These findings are consistent with a model suggesting that prayer frequency promotes a more negative view of substances both directly and indirectly through cultivating a greater sense of purpose in life.

Abstract In a career spanning over forty years, Wilson Harris stands paradoxically both inside and outside "postcolonial fiction". His almost‐surrealist style holds many similarities to postcolonial mediations on the often‐fragmented nature of postcolonial identity. Yet Harris's pursuit of slivers of spiritual truth, in an age when universals are no longer popular, places him strangely outside its discourses. Such diverse strands are explored through magical re‐appraisals of space, re‐visionings that encompass post‐modern thought, chaos theory, Western literary history and the cultures of the Caribbean and Latin America. Key to such representation is the figure of Anancy as trickster. Referring to Anancy in Jonestown (1996), Harris evokes a complex web of images ‐ carnival, mask, limbo and phantom‐limb ‐ which illustrates a development from Palace of the Peacock (1960). Harris transforms the figure of hoaxer, so that it is not a faking of the past that is envisaged, but rather a re‐making of the past.


We investigated the effect of the wing–wing interaction, which is one key aspect of flight control, of damselflies (Matrona cyanoptera and Euphaea formosa) in forward flight that relates closely to their body morphologies and wing kinematics. We used two high-speed cameras aligned orthogonally to measure the flight motions and adopted 3D numerical simulation to analyze the flow structures and aerodynamic efficiencies. The results clarify the effects of wing–wing interactions, which are complicated combinations of biological morphology, wing kinematics and fluid dynamics. As the amplitude of the hindwing of M. cyanoptera is larger than that of E. formosa, the effect of the wing–wing interaction is more constructive. Restricted by the body morphology of E. formosa, the flapping range of the hindwing is below the body. With the forewing in the lead, the hindwing is farther from the forewing, which is not susceptible to the wake of the forewing, and enables superior lift and thrust. Because of the varied rotational motions, the different shed direction of the wakes of the forewings causes the optimal thrust to occur in different wing phases. Because of its biological limitations, a damselfly can use an appropriate phase to fulfill the desired flight mode. The wing–wing interaction is a compromise between lift efficiency and thrust efficiency. The results reveal that a damselfly with the forewing in the lead can have an effective aerodynamic performance in flight. As an application, in the design concept of a micro-aircraft, increasing the amplitude of the hindwing might enhance the wing–wing interaction, thus controlling the flight modes.

Future wireless communication networks and systems are expected to reliably provide data services with data rate requirements ranging from a few kbps up to some Mbps and, due to the high costs of frequency spectrum, these systems also need to be extremely efficient in terms of the spectrum usage. In particular, the application of transmission schemes based on OFDMA and on MIMO is considered as a promising solution to meet these requirements.
On the one hand, MIMO-OFDMA systems are flexible and spectrally efficient but the considerably large number of subcarriers and the inclusion of the space dimension make the RRA in such systems very complex. In fact, the optimum RRA that maximizes the sum of the users' data rates is often too complex for practical application. Consequently, suboptimal rather efficient and low-complexity RRA strategies are required in order to allocate the frequency, power, and space radio resources of the system to the users of the system.
This doctoral thesis deals with RRA strategies in the downlink and uplink of OFDMA systems, the downlink of MISO-OFDMA systems, and the downlink of MIMO-OFDMA systems aiming at the maximization of the sum of the users' data rates guaranteeing proportional data rates or minimum data rates among users. In order to solve the problem of maximizing the sum of the users' data rates with affordable complexity in each one of the aforementioned cases, new suboptimal algorithms are proposed.
In the SISO downlink the objective is to maximize the sum of the users' data rates subject to constraints on the total available power and proportional data rates among users. The proposed method, which is also complexity effective, consists of three algorithms; an algorithm that determines the number of subcarriers for each user, a subcarrier allocation algorithm by dividing the users in two groups and the water-filling algorithm. The first two algorithms assign the available subcarriers to the users of the system and the third one allocates the available power optimally in order to maximize the sum of the users' data rates.
In the SISO uplink the objective is to maximize the sum of the users' data rates subject to constraints on per user power and minimum data rates among users. The proposed scheme, which is also complexity effective, consists of three algorithms; an algorithm that determines the number of subcarriers for each user, a subcarrier allocation algorithm by dividing the users in two groups and the water-filling algorithm. The first two algorithms assign the available subcarriers to the users of the system and the third one allocates the available power.
In the MISO downlink three user selection and resource allocation algorithms for multiuser downlink systems are developed that are less complex than other approaches and incorporate fairness. In the first two algorithms proportional constraints among the users' data rates are imposed and in the third algorithm minimum data rate constraints are taken into account. The proposed algorithm that maximizes the sum of the users' data rates with proportional data rate constraints is also applied to DAS and subcarriers are grouped to chunks. Simulation results sustain their effectiveness in distributing the sum data rate fairly and flexibly among users and that in DAS higher sum of the users' data rates are obtained.
Finally, in the MIMO downlink the problem is formulated in order to maximize the sum of the users' data rates subject to total available power constraint with controllable bandwidth introducing system parameter α. Since this optimization should be performed in real time, an efficient, suboptimal and complexity effective algorithm is proposed which shows reasonable loss with respect to the unconstrained case where the only target is the maximization of the sum data rate and impressive profit compared to static TDMA scheme.
Apart from the theoretical analysis of the above algorithms, simulation code, which was created based on realistic assumptions and simplifications, gave us results which measure the sum of the users' data rates that provide each one of the aforementioned algorithms and examine the possible appropriateness for use in specific environments. The final concluding results are that MIMO-OFDMA systems are able to offer real broadband services over the wireless communication channel.

Electrical drives consume a great amount of the world's energy, and this will keep increasing due to the electromobility trend. Hence, the efficiency of electrical drives must be improved to reach sustainability. Silicon Carbide devices have a high working frequency and lower switching loss, increasing the device efficiency. Nevertheless, higher operation frequencies may bring major Electromagnetic Compatibility issues, in addition to insulation stress and higher bearing currents. This paper presents the simulation process to obtain a high-frequency model of an electrical machine. Then, some small and controlled coils are modelled to construct the high-frequency model step by step, analysing the slight differences between conductor diameters and materials that would be difficult to see in a machine. These models are validated with experimental impedance measurements. This represents the first step in modelling an electrical machine equivalent circuit to predict the electromagnetic interference levels from the design stage.

Objective: In the present research, the clinical course of pediatric uveitis was studied by examining the demographic characteristics of afflicted children, the results of clinical examinations, and uveitis complications. Materials and Methods: The present research was a retrospective study in which the medical records of 243 children who had been visited and diagnosed as uveitis in the uveitis clinic of Nikookari Eye hospital of Tabriz in 2003-2015, were reviewed. The data were statistically analyzed by descriptive statistics and mean comparison tests in IBM-SPSS 23 and the significance level of P<0.05. Results: According to the results, 73 (30%), 146 (60.1%), 12 (4.9%), and 12 (4.9%) eyes diagnosed with uveitis had anterior, intermediate, posterior, and panuveitis type, respectively. In addition, 73 cases of uveitis (30%) were acute and 170 cases (70%) were chronic. Based on the LogMAR chart, the mean visual acuity before and after treatment was 0.39 and 0.15 for the right eye and 0.4 and 0.09 for the left eye, which suggests a significant difference. The most common complications observed in this study were macular edema (32.5%) and cataract (22.6%). Conclusion: This study indicates that intermediate uveitis is the most common type of pediatric uveitis, while anterior uveitis is the second. Posterior and panuveitis are less common in our study. The prevalence of chronic uveitis is significantly high in pediatric group which could justify the higher rate of complications in this age group.

The method of determining neutral points, corresponding to vanishing frequency in wavenumber space, is applied to the case of gamma-ray bursts (GRBs) to determine low-frequency instabilities. If a particular particle distribution function permits the existence of neutral points, instability is guaranteed on one side or the other of the neutral point. By using the rest frame of the GRB jets, only perpendicular particle motion has to be taken into account. The discussion is limited to the cases of a monoenergetic electron-proton plasma with stationary protons and also to a symmetric electron-positron plasma. In the limiting case of wave propagation perpendicular to a homogeneous background magnetic field, taken to be parallel to the streaming direction of the jet, it is shown that to lowest order in the wave frequency, unstable aperiodic fluctuations occur that grow very rapidly on timescales comparable to or smaller than the characteristic times of the GRB, leading to the conclusion that the jets most likely consist mainly of electron-proton plasmas for the cases investigated. Furthermore, high electron Lorentz factors, as well as the coupling effect between longitudinal and transverse modes, are shown to stabilize the system.


The article analyzes our own data and data from the literature on the study of plant–pathogen interactions in the pathosystem of Puccinia triticina and host plants of the genera Triticum and Aegilops with different ploidy and genomes. We characterize the long-term variability of the Russian populations of the pathogen, caused by the cultivation of genetically protected cultivars of common wheat (T. aestivum). Differences of the pathogen's virulence on hexaploid species T. aestivum and tetraploid wheat (T. durum) are shown. Data on the pathogen's virulence on other hexaploid, tetraploid, and diploid relative species Triticum sp. and Aegilops sp. are presented. Adaptation and specificity to the host plant were shown as the key driving factors in the evolution and divergence of clonally propagating phytopathogens, which include leaf rust.


The No.S2S9 coal face in Daping was taken as a prototype to study the characteristics of the soft overburden movement and the strata behavior in mining of thick coal seam.The essential stress and strain were all monitored in the similar material model.The results showed that rock fractures extended from bottom as the workspace was pushed,with the initial collapse span of 20 m,the roof collapse span of 34 m,the cycle collapse span of about 10 m,the mining zone of 21 m and the water flowing fractured zone of 120 m.The anterior coal wall,where large plastic zone appears,lost the bearing capacity along with the advance of the workspace.The range of the internal stress field was about 10 m and the peak abutment pressure point is 80 m away from the coal wall,while the distur-bance range in the anterior coal wall was 200 m.Some cracks were closed in later stages.The simulation provides a reference for the application and promotion of thick seam mining technology.

The specialty setting and employment guidance in colleges and universities are usually worked out based on empiricism. Data mining technology is rarely used to guide it. In recent years, under the background of Belt and Road Initiative, many schools have offered foreign the majors related to foreign trade English. What is the setting of these majors and the employment satisfaction of graduates? Both have an impact on social and economic development. Access to this information in a timely manner becomes the key. In this paper, the rough set theory, a data mining technology, is used to solve this problem. First of all, this paper collects the employment statistics of foreign trade English graduates from Guangxi Talent International College. Secondly, based on the rough set theory, the quantitative measurement method of college students' employment satisfaction research is put forward, and the intelligent data analysis model based on rough set is established. The experimental results show that the new method is effective and can provide some references for school employment guidance and the training of foreign trade English majors. Finally, the resolution matrix of rough set is used to reduce the attributes of the evaluation data and reduce the unnecessary evaluation indexes. The experimental results show that the evaluation method after the statute is more efficient.

Introduction and Scientific Objectives A PRIMARY objective of the CRRES mission is to examine the effects of the radiation belt environment on a variety of microelectronic components by making comprehensive and simultaneous environmental measurements. Other objectives include new static and dynamic models and descriptions of processes in the radiation belts. These objectives require knowledge of the Earth's magnetic field, and its variations, which are important for the study of all space plasma processes, including control of the source, loss, and energization of radiation belt particles. The fluxgate magnetometer makes the magnetic field measurements that are required to satisfy these major mission objectives. CRRES was launched on July 25, 1990, at 1921 UT. In the initial CRRES orbit (period = 9 h 52 min, inclination = 18.2 deg, perigee = 350 km, apogee = 6.3Re, and initial magnetic local time of apogee = 8 MLT), the magnetometer must have a large dynamic range to measure magnetic fields from fractions of a nanotesla to about 45,000 nT (1 nT = 10 ~ 9 T). These measurements will be used 1) together with the look angles of the particle experiments to obtain the pitch angle of the measured particles; 2) as a diagnostic of global and local geomagnetic disturbances and current systems; 3) as a diagnostic of low-frequency waves in the ambient environment and to study wave-particle interactions; 4) to provide plasma gyrofrequencies; 5) to measure v x B electric fields; 6) to support chemical release activities; and 7) to provide a secondary source of spacecraft attitude information.


An Ultra-Wide Bandwidth (UWB) system usually operates by using impulse on the order of a nanosecond. It is very difficult to synchronize among the system users. Based on the Time-Division Multiplexing (TDM) protocol, this paper presents a net-like UWB system. With the help of synchronization provided by the synchronization station, each user transmits data to other users at the assigned time. Simulation results and theoretical analysis indicate that the more synchronization impulses are used in one synchronization frame, the higher the synchronization probability.
