Objective:To measure nuclear DNA content of invasive bone tumor with flow cytometry(FCM) and to analyse the relationships between DNA content and prognosis of disease.Methods:From March 1992 to March 1993,20 fresh surgical specimens from patients with primary invasive bone tumor was measured for DNA content with FCM,all patients were followed up at least for 6 years.Results:Patients with DNA diploid,lower S phase cell percentage,PI had lower recurrence rate,but patients with aneuploid,and highter S%、PI had higher recurrence rate.Conclusion:This study indicates that patients with diploid be inclined to binign,the resection can be bordered or scraping and extinctive,while patients with DNA aneuploid be inclined to malignant and the extend of local resection of turmors should be more extensive or radical.


This study attempts to quantify the relative contributions of vegetation greening in China due to climatic and human influences from multiple observational datasets. Satellite measured vegetation greenness, Normalized Difference Vegetation Index (NDVI), and relevant climate, land cover, and socioeconomic data since 1982 are analyzed using a multiple linear regression (MLR) method. A statistically significant positive trend of average growing-season (April–October) NDVI is found over more than 34% of the vegetated areas, mainly in North China, while significant decreases in NDVI are only seen in less than 5% of the areas. The relationships between vegetation and climate (temperature, precipitation, and radiation) vary by geographical location and vegetation type. We estimate the NDVI changes in association with the non-climatic effects by removing the climatic effects from the original NDVI time series using the MLR analysis. Our results indicate that land use change is the dominant factor driving the long-term changes in vegetation greenness. The significant greening in North China is due to the increase in crops, grasslands, and forests. The socioeconomic datasets provide consistent and supportive results for the non-climatic effects at the provincial level that afforestation and reduced fire events generally have a major contribution. This study provides a basis for quantifying the non-climatic effects due to possible human influences on the vegetation greening in China.


Sequence data can potentially increase the reliability of multi breed genomic prediction by containing causative variants or markers in in high linkage disequilibrium (LD) with those. Sequence data does, however, also contain a large number of variants in low LD with the causative mutations, limiting the potential increases in prediction reliability when the full sequence would be used directly for genomic prediction. The objective of this study was to use sequence variants to increase the reliability of multi breed prediction in dairy cattle. First, a simulation study based on real sequence data was carried out to investigate how sequence variants can improve the reliability of across breed prediction. The simulation study used the regression of genomic relationships at causative mutations on genomic relationships at prediction markers to measure the loss in prediction reliability as a consequence of using markers in imperfect LD. It was concluded that it is important to use only variants very close to the causative mutations. In the second part a number of two component Bayesian SNP BLUP models were used, where the first component mainly model variation within the breeds, while the second component model covariance across the breeds. Here, sequence variants selected from a multi breed GWAS for production traits were used as prediction markers in the second component. Different models and selection strategies were compared. Large increases in reliability, up to 0.10, were observed for multi breed prediction using QTL variants compared to within breed prediction using only 50K markers. Our results show that using a selective number of sequence variants can result in large increases in reliability, but careful selection of the variants is essential


Landsat Multispectral Scanner (MSS) data were used to characterize land cover types, land cover changes, and landscape patterns in the Northern Forest region of Vermont, New Hampshire, and western Maine, USA. Eight Landsat MSS scenes from 1973, 1978, 1984/85, and 1990/91 were used to cover the regional study area and 18-year time period. Four watershed segments within the Northern Forest area were analysed: the Lamoille River watershed (151814 ha), the Connecticut River watershed (706880 ha), the Androscoggin River watershed (655445 ha), and the Kennebec River watershed (457168 ha). Multitemporal analysis indicates that the percentage of forested land that was converted to open land in each watershed over the 18-year period is similar, and is estimated to be approximately 10% of the forested land in each watershed segment.


The power electric distribution systems (PEDS) possess a great dynamics of development. Thanks to this phenomenon in the power electric distribution systems (PEDS) the probability of apparatus of asymmetrical regimes increase monotonously. As a result of this reliability of the functioning of the power electric equipment installed in the electric knots changes. The asymmetrical regimes in the power electric distribution systems (PEDS) accompanied by the short circuit current are a function of a row determinate is a vague factor of probabilistic nature. Coming from it follows that the investigation of the influence of the asymmetrical regimes accompanied by the current of the short circuit on the reliability of the Power Electric Distribution Systems (PEDS) is one of the most important problems of the development the Power Electric Distribution Systems. The short circuit currents influence the structural and functional reliability of distribution networks and at the reliability of electrical equipment installation. The dynamics of changes in the levels of short circuit currents in electrical networks depends on the rate of change of the re-recovering voltage at the short circuit point on the power supply side and on the load side, as well as on the magnitude and rate of power change at the short circuit point on the power source side and on the load side.


Joseph F. Byrnes* The Lost Catholic Patrimony1 When Emile Male deciphered the art programs of the French medieval cathedrals, and, in fact, religious art from the twelfth to the eighteenth centuries, he rediscovered a culture2-clerical, artistic, and popular-that had been expressed in the art.3 Over a period of thirty-four years Male published four great syntheses of religious art history. Each synthesis was effected in a different manner, depending upon the sources used to explain the subject matter and the media employed by the artists. In L'Art religieux du XIII sic in L'Art religieux du XIII siecle en France (1922), it was St. Bernard, Suger, and the great abbots of Cluny; and in L'Art religieux apres le concile de Trente (1932), it was the theologians of the Counter-Reformation.4 To put it another way, the unity, the synthesizing principle of the epoch and of Male's own work, was thought for the thirteenth century, sentiment at the end of the Middle Ages, the monastic impulse (powerful monastic foundations produced and patronized both religious activity and artistic expression) for the twelfth century, and church authority, organized for defensive-and offensive-action, in the period after the Council of Trent. But thought, sentiment, movement, and institution exist in cultures: elite clerics, artists, and religiously active people from various levels of the social hierarchy-from princes to poor intellectuals and, yes, even some of the farmers and small merchants-transmuted their experiences into a common religious culture.5 In Male's hands, iconography, generally understood to be the classification and interpretation of images, became a study of the ideas and methods that produced the images and of the culture that produced the ideas and methods. The subtitle of his first book, "A Study of Medieval Iconography and its Sources of Inspiration," makes it clear that iconography is, in its primary sense, the actual artistic expression of ideas; secondarily, it is the study of this artistic expression. His achievement was uniquely different from the cataloguing, conservation, and restoration of medieval monuments effected by Arcisse de Caumont, Alexandre Lenoir, Antoine Quatremere de Quincy, Alexandre du Sommerard, and Eugene Viollet-le-Duc; uniquely different, also, from the deciphering efforts of Adolphe-Napoleon Didron, the clerical team of Cahier and Martin-and Roger Gaignieres long before them.6 The religious art of the Middle Ages was not a monument to be preserved and reverenced, a lieu de memoire where one could meditate on France as Nation and Republic.7 Male confronted his colleagues and readers with a French way of life of another age. It was that culture, as signified in the art and reconstituted in his prose, that became the lieu de memoire. My goal is to demonstrate how Male's achievement derives from his powers to place his own culture, the intellectuals and educated readers of the Third Republic, in contact with medieval Catholic culture. He thereby gained broad acceptance of this culture as an element of the French national patrimony. Formation: Republican and Catholic The Third Republic was born in turmoil, political and religious. In 1871, the Paris Commune, inspired by an exaggerated revolutionary Republicanism, was accompanied by an anticlerical violence that culminated in the execution of the Archbishop of Paris, Georges Darboy. In reaction, the new National Assembly, led by monarchists, voted for public prayers of reparation, a vote reinforced by the activities of mayors, magistrates, and army officers. Early rivalry of the leading Republicans, the Moderate Adolphe Thiers and the Opportunist Leon Gambetta, gave way before the electoral success of the monarchist general Patrice MacMahon and his government of "Moral Order. …

We demonstrated a novel twin-core fiber grating sensor system for accurate and simultaneous measurements of temperature and strain. Specifically, we designed two cores with custom index and dopant profiles such that the gratings in these two cores have different temperature coefficients, but almost same strain coefficients. Our data also showed that both gratings had almost the same wavelength shift at the same deuterium concentration level in the fiber. This, together with the strain characteristics of the gratings, enables us to isolate the temperature measurement when strain, temperature and gaseous diffusion all apply to the sensor simultaneously. It makes our grating sensor extremely useful for hydrothermal down-hole temperature mapping applications.


Based on the principle of Helferich reaction,β-arbutin was obtained from hydroquinone and α-D-glucose as the starting material via acetylation,condensation,secondary acetylation and deacetylation.The optimal condition was confirmed by studied,catalyst,temperature,recrystallization on the preparation of β-D-glucopyranosyl pentaacetate,and get β-D-glucopyranosyl pentaacetate with no α type residual,purity of 100%,yield of 75.6%.In addition,the new design of condensation reaction was that the acetylation of hydroquinone was after the condensation of hydroquinone and β-D-glucopyranosyl pentaacetate.The effect of solvent,catalysts,mole ratio of reactants,reaction time and reaction temperature on the yield were investigated.The two steps together optimized yield was 80%.Finally through the deprotection got β-arbutin with purity of 99.9% and yield of 80%,melting point of the compound were consistent with those reported,and the structure of product was confirmed by 1H NMR.The reaction can proceed well at atmospheric pressure,easy to gain materials and the yield was high,and simple to operate.This method is suitable for preparation on a small scale in the laboratory,also suitable for large-scale industrial production.


A review of the history of programs for the study of higher education reveals several rationales for their existence. The earliest rationale argued that people devoting their lifetime to careers in colleges and universities would function better in that setting if they had studied the history and organization of higher education. A later rationale gave credence to former administrators training people in these programs who would become the next generation of administrators. A third rationale justified the programs on the basis of the reliable knowledge about higher education that they generate.


Accession appears to be both a blessing and a curse to transition countries. On the one hand, EU membership supports their transformation from authoritarian regimes with centralized planning economies into liberal democracies with market economies. On the other hand, the accession countries face great difficulties in restructuring their economic and political institutions in order to meet the conditions for EU membership. The systematic involvement of private actors in the adoption of and adaptation to EU requirements was thought to be a remedy for the problems of European Enlargement towards "weak" transition countries. Companies and civil society organizations could provide the governments of the accession countries with important resources (money, information, expertise, support) that are necessary to make EU policies work. The paper explores the role of private actors in governing the double challenge of transition and accession. A comparative study of implementation of environmental policies in Poland, Hungary and Romania shows that the accession of the three transition countries was mainly shaped by the shadow of the past. State actors were harking back on command and control regulation that left little room for public involvement. Even where the policy process was successfully opened up for new actors, the shadow of hierarchy was maintained. The paper argues that both state and nonstate actors in transition countries are often too weak to make new modes of governance work. The double weakness of transition countries seriously constrains the empowering of non-state actors by "Europeanization through accession".


as my father and grandfather were also members of our great profession I thought I would try and look at life as it was since 1846 when my grandfather obtained his qualificationi of L.R.C.S. in Edinibuirgh, inci(denltally he was Presi(lent of this Society in 187576. During that early period what great names were brought before the students. Moses, the first great doctor in Egypt, laid down laws of health and made the Israelites follow a code of regulations for their cleanliness and well-being which preserved them in health for forty years wandering in the wilderness. Probably segregation of the leper, often referred to in Leviticus, was the first great feat of preventive medicine. Hippocrates died over two thousand years ago, but his solemn oath which his students took to respect their teachers as a father, to share knowledge freely, to behave with stainless honour, and never to divulge a secret learned in the sickroom, still remains. Galen was born in A.D. 130. He gathered together all the safest teaching of those who had gone before him and added to these the results of his own observations. For a thousand years the teaching of Galen was all that Europe had to go upon in the science of curing disease. About fourteen hundred years later William Harvey appeared on the scene and it was his great mind that discovered the circulation of the blood and laid the real foundation 129


I am not taking a pop at doctors - honest - but I am surprised by Dr Wicce St-Clair Gray's remarks about nurses encroaching on medics' territory to 'cherry-pick' the interesting jobs for themselves (news March 2). I would have thought that someone who was a nurse prior to undertaking medical training would have a more rounded view of the issues relating to multiprofessional education and training, and the shifting professional boundaries that we all will be increasingly subject to.


ABSTRACT Identifying and assessing the likelihood and consequences of maritime accidents has been a key focus of research within the maritime industry. However, conventional methods utilised for maritime risk assessment have been dominated by a few methodologies each of which have recognised weaknesses. Given the growing attention that supervised machine learning and big data applications for safety assessments have been receiving in other disciplines, a comprehensive review of the academic literature on this topic in the maritime domain has been conducted. The review encapsulates the prediction of accident occurrence, accident severity, ship detentions and ship collision risk. In particular, the purpose, methods, datasets and features of such studies are compared to better understand how such an approach can be applied in practice and its relative merits. Several key challenges within these themes are also identified, such as the availability and representativeness of the datasets and methodological challenges associated with transparency, model development and results evaluation. Whilst focused within the maritime domain, many of these findings are equally relevant to other transportation topics. This work, therefore, highlights both novel applications for applying these techniques to maritime safety and key challenges that warrant further research in order to strengthen this methodological approach.


Stocks, which are ownership shares in the company, can be issued and traded on the platform known as a stock exchange by publicly traded companies. A centralized marketplace is provided by a stock exchange where stocks can be traded by buyers and sellers coming together, thereby ensuring liquidity and price transparency. Large studies have been conducted for a long time in regions such as foreign exchange, stock prices, and weather reviews where time series forecasting information has been comprised. In our research work, we will use time series data because time series allows us to compare what elements have an effect on certain variables from time to time. The primary goal of this review paper is to provide a comprehensive overview of the research conducted by various scholars on predicting stock market prices using time series data. Evaluating time series data can provide valuable insights into the changes in a particular asset, security, or financial variable over time. Forecasting techniques using time series analysis are employed in both fundamental and technical analysis.


Precast segmental construction offers many advantages, such as construction economy, simplicity of construction, and reduced maintenance cost. Repeated loading due to moving vehicular loads on the bridges may soften the concrete in due course of time and cause early cracks and larger deflections. This loading in segmental bridges may also cause openings of the joints between the segments. This paper presents the results of an experimental study of a single cell precast posttensioned segmental box bridge system subjected to cyclic loading and temperature changes. The test bridge system is a 1:3.5 scale model of the Long Key Bridge in the Florida Keys. The behavior of the bridge model was examined under fatigue loading, with emphasis on joint performance and flexural stiffness. The temperature distribution of the bridge system was also measured, and compared with analytical predictions. The performance of the bridge model was evaluated in terms of deflections, strains in the concrete and strains across the joints, and cracking behavior of joints between the segments with an increasing number of cycles of fatigue loading. The studies indicated that the behavior of joints between the segments under static and fatigue loadings was satisfactory up to two million cycles. No joint openings or cracks were observed at the joints under the loading. The temperature distribution of the bridge model was also studied using finite-element analysis and the predicted temperatures across the cross section were compared with the observed values.


[1] Tropical deep convection and its dynamical effect on the tropopause and stratosphere are investigated using a suite of data from the Upper Atmospheric Research Satellite (UARS) Microwave Limb Sounder (MLS), including upper tropospheric humidity, cloud radiance, and gravity wave measurements. For this purpose, geographical distributions of temperature, water vapor, and cloudiness in the tropical tropopause layer (TTL) are compared with corresponding maps of gravity wave variance in the stratosphere. In addition, ECMWF global wind divergent and velocity potential fields as well as NOAA outgoing longwave radiation and CMAP rainfall data are analyzed to help pinpoint the locations of deep convection. We found that high-altitude clouds near the bottom of TTL (∼147 hPa) are usually surrounded by high-humidity air, and their spatial pattern and seasonal variability are closely associated with regions of vigorous summertime deep convection. Upward propagating gravity waves generated from these convection regions are shifted poleward by prevailing stratospheric winds. We estimate that tropical deep convection lifts ∼5% of the cloud tops to altitudes above 100 hPa and that most of the extreme deep convection events occur in the Western Pacific and Indian monsoon regions. Low-temperature regions in the TTL are associated with, but often drift away from, the center of deep convection. Regions of water vapor maxima near the bottom of TTL are located directly above the deep convection centers, but this moisture behavior is somewhat reversed at the top of the TTL. The integrated picture derived from this study implies that convective scale motions could be important in affecting short-term dehydration processes in the TTL. Our results also suggest that the spatial organization and temporal development of tropical convective systems will be better monitored with the follow-on Earth Observing System (EOS) Aura satellite instruments and lead to improved understanding of the complex interaction of tropical convection with large-scale dynamic and thermodynamic conditions.


We consider a chemical nonequilibrium model to describe the pion production in Ar+KCl and La+La collisions at initial energies {ital E}{sub lab}=0.5--1.8 GeV/nucleon. The excess of low-energy {pi}{sup {minus}} is interpreted as the manifestation of positive chemical potential of {pi}{sup {minus}} at the thermal freeze-out. We find that in collisions between nuclei with large atomic numbers the chemical potential of {pi}{sup +} is smaller than that of {pi}{sup {minus}}. This leads to the prediction of much less excess of low-energy {pi}{sup +}, than as measured in the {pi}{sup {minus}} case, in heavy-ion collisions at bombarding energies in the region of 1 GeV/nucleon.


Mentor magazine is a quarterly magazine which contains wider reading to inspire aspiring healthcare students and provides opportunities for omni-directional mentorship. The magazine is a multidisciplinary project, as reflected in its leadership team consisting of medical, veterinary and dental students. Taking a One Health approach has resulted in a publication which demonstrates collaborative working and the transferable nature of healthcare skills to future leaders. Mentoring prospective healthcare students in writing an article develops the ability to act on feedback and respond appropriately to constructive criticism. Opportunities to publish outside of the school curriculum encourage students to seek challenges consistent with a growth mindset. A survey was created to map skills learned to the Medical Leadership Competency Framework's areas for leadership and management development, to ensure that processes were shaping future healthcare leaders. Initial data is overwhelmingly positive: 77% of contributors would recommend writing for the magazine. Students feel they learned how to use feedback to develop their skills (69%), learned how to critically appraise scientific literature (58%) and learned about the process of mentoring (58%). Open-text feedback shows that contributors enjoy the process: 'it's satisfying and rewarding'; 'it is an amazing experience in which you...develop essential skills'. This project has shown that the skills of healthcare leadership can be developed at the earliest career stages. To meet growing demand, the publication portfolio of Mentor was remodelled to contain content written by undergraduate students and qualified healthcare professionals. Once the new portfolio has been launched, a follow-up survey will be sent to subscribers and contributors. We feel we have implemented a streamlined process for students to develop key leadership and management skills with the support of more experienced student editors.

SUMMARY
Microtubule arrays were studied in Spiranthes sinensis (Pers.) Ames protocorms cultured in vitro either asymbiotically or symbiotically with the fungus Ceratobasidium cornigerum (Bourdot) Rogers by localizing β-tubulin in hand sections observed with laser scanning confocal microscopy. Cortical microtubules present in uncolonized cells disappeared when cells became colonized by the fungus. However, microtubules were observed between the hyphae forming hyphal coils (pelotons) in colonized cells. In these cells a close relationship between pelotons, microtubules and nuclei was often observed, and microtubules associated with hyphae formed a net-like structure through the pelotons. During senescence and condensation of the pelotons, microtubules were observed surrounding the pelotons, between collapsing hyphae and as circular profiles within the collapsed hyphal masses. In cells which contained completely collapsed hyphal masses and which were not recolonized, cortical microtubules reappeared and continued from the cell periphery through the hyphal remains to the collapsed hyphal masses. Microtubules associated with hyphae seemed to be involved in the condensation of hyphal masses in the host cells. Microtubules were also observed within hyphae, except in those which were collapsing or had collapsed.

There are many feature extraction methods for face recognition. We need a new method to overcome the small sample problem that the number of feature variables is larger than the sample size for face image data. The paper considers partial least squares(PLS) as a new dimension reduction technique for feature vector. Principal Component Analysis(PCA), a conventional dimension reduction method, selects the components with maximum variability, irrespective of the class information. So, PCA does not necessarily extract features that are important for the discrimination of classes. PLS, on the other hand, constructs the components so that the correlation between the class variable and themselves is maximized. Therefore PLS components are more predictive than PCA components in classification. The experimental results on Manchester and ORL databases shows that PLS is to be preferred over PCA when classification is the goal and dimension reduction is needed.


There are some disadvantages, how ever, the main one being the problem of shear stability. When a multigraded oil is subjected to a shear stress, as is found in an operating engine, the viscosity is de creased. This decrease is caused by the degradation or mechanical breakup of the long polymers commonly known as VI improvers. A secondary disadvantage is the temporary viscosity loss found in multigraded oils, a transitory effect, for when the shear rate is lowered the vis cosity increases to a higher valuea. This temporary loss is brought about by the "lining up" of the polymer molecules in the direction of the shear, hence lessening their effect on viscosity (3).


: Formulaic sequences are an important aspect of writing development. Studies of language processing have shown that multiword units are processed as a single unit by native speakers. Little research, however, has been conducted on formulaic sequences in Portuguese (Sardinha, Teixeira, and Ferreira 2014; Ferreira 2014), and none of those have described the development of the use of formulaic sequences across learners of Portuguese. This study examines the use of lexical bundles, sequences of three or more words that frequently occur in a corpus, in written texts across five proficiency levels (N=572). Three-word bundles were identified based on their dispersion in each subcorpora. The extracted bundles occurred in at least 4% of the texts in the corpus. These bundles were then classified based on their structure in noun, verb, preposition, adverb, clause, and pronoun-based bundles. The results of this study indicate that lower-level learners tend to use fewer bundle types but more bundle tokens. In addition, pronoun-based bundles are more frequent in lower-level texts, while clausal and adverb-based bundles are more frequent in advanced levels. The results can be used to inform the teaching and material development of Portuguese as a second language.


Background: Biosynthesis of complex metal cofactors in [NiFe] hydrogenase is sensitive toward molecular oxygen. Results: A rubredoxin-like protein is required for hydrogenase maturation under aerobic conditions. Conclusion: The rubredoxin-like protein prevents oxidative damage of metallocenters, including the recently discovered [4Fe3S] center. Significance: Dedicated protection mechanisms enable biosynthesis of sophisticated metal centers in the presence of dioxygen. The membrane-bound [NiFe] hydrogenase (MBH) supports growth of Ralstonia eutropha H16 with H2 as the sole energy source. The enzyme undergoes a complex biosynthesis process that proceeds during cell growth even at ambient O2 levels and involves 14 specific maturation proteins. One of these is a rubredoxin-like protein, which is essential for biosynthesis of active MBH at high oxygen concentrations but dispensable under microaerobic growth conditions. To obtain insights into the function of HoxR, we investigated the MBH protein purified from the cytoplasmic membrane of hoxR mutant cells. Compared with wild-type MBH, the mutant enzyme displayed severely decreased hydrogenase activity. Electron paramagnetic resonance and infrared spectroscopic analyses revealed features resembling those of O2-sensitive [NiFe] hydrogenases and/or oxidatively damaged protein. The catalytic center resided partially in an inactive Niu-A-like state, and the electron transfer chain consisting of three different Fe-S clusters showed marked alterations compared with wild-type enzyme. Purification of HoxR protein from its original host, R. eutropha, revealed only low protein amounts. Therefore, recombinant HoxR protein was isolated from Escherichia coli. Unlike common rubredoxins, the HoxR protein was colorless, rather unstable, and essentially metal-free. Conversion of the atypical iron-binding motif into a canonical one through genetic engineering led to a stable reddish rubredoxin. Remarkably, the modified HoxR protein did not support MBH-dependent growth at high O2. Analysis of MBH-associated protein complexes points toward a specific interaction of HoxR with the Fe-S cluster-bearing small subunit. This supports the previously made notion that HoxR avoids oxidative damage of the metal centers of the MBH, in particular the unprecedented Cys6[4Fe-3S] cluster.

The invention discloses a soft switching grid-connected inverter, which is used for converting direct current generated by reclamation equipment into alternating current, and then the alternating current is fed into a power grid; the inverter comprises a digital signal processor, a quasi-resonant flyback DC (Direct Current)-DC circuit and a DC-AC (Alternating current) inverter circuit, wherein the quasi-resonant flyback DC-DC circuit receives direct current generated by the reclamation equipment; after the direct current is processed, the direct current is sent into the DC-AC inverter circuit; after being processed by the DC-AC inverter circuit, the direct current is converted into sine wave alternating current having the same frequency and the same phase position with the power grid; then the sine wave alternating current is fed into the power grid; the digital signal processor calculates the maximum power point by detecting the input voltage and the current signal of the quasi-resonant flyback DC-DC circuit; and a control signal is output according to the maximum power point to control the quasi-resonant flyback DC-DC circuit and the DC-AC inverter circuit. The soft switching grid-connected inverter disclosed by the invention takes the digital signal processor as a grid-connected inverter control core to convert resonant soft switching, lower heat waste and improve output efficiency.


We study the current definition of classifier error in XCSF and we discuss the limitations of the algorithm that is currently used to compute classifier error from online experience. We introduce a new definition of classifier error and study the performance of two novel estimation algorithms based on this definition. Our results suggest that the new estimation algorithms can be more robust and improve system generalization.


Due to their high efficiency and their strong security properties, lattice-based cryptographic schemes seem to be a very promising post-quantum replacement for currently used public key cryptography. The security of lattice-based schemes has been deeply analyzed mathematically, whereas little effort has been spent on the analysis against implementation attacks. In this paper, we start with the fault analysis of one of the most important cryptographic primitives: signature schemes. We investigate the vulnerability and resistance of the currently most efficientlattice-based signature schemes BLISS (CRYPTO 2013), ring-TESLA (AfricaCrypt 2016), and the GLP scheme (CHES 2012) and their implementations. We consider different kinds of (first-order) randomizing, zeroing, and skipping faults. For each of the signature schemes, we found at least six effective attacks. To increase the security of lattice-based signature schemes, we propose countermeasures for each of the respective attacks.


Web pages polluted by unhealthy contents (e.g. pornography or violence) have offended many users and become a social headache. This paper presents a collaborative rating system and a light-weight algorithm to detect polluted pages and thus improve user experience of web browsing. It mainly tackles two challenges. First, the system should cater to web users' different tastes and judging standards on which polluted pages they like or dislike. Second, the system should be resilient to dishonest ratings and collusions. The model and the algorithm are evaluated by simulations which show that they can work well.


Polygonal meshes are used in many areas to model different objects and structures. Depending on their applications, they sometimes have to be processed to, for instance, reduce their complexity (simplification). This mesh processing introduces error, whose evaluation is important when choosing the kind of processing that is to be done for a particular application. Although some mesh comparison tools are described in the literature, little attention has been given to the way results are presented. A tool is presented which enhances the way users perform mesh analysis and comparison, by providing an environment where several visualization options are available and can be used in a coordinated way.


This article looks at the problems of integration experienced by immigrants from the Maghreb. Economic, social, political and cultural aspects all influence integration. In the labour market, immigrants tend to target sectors which demand minimal professional qualifications and offer salaries below those of the non-immigrant population. In the social arena, two aspects stand out; schooling and housing. The children of immigrants experience difficulties at school due to material and social conditions, but also as a result of cultural diversity. As regards housing, immigrants tend to gravitate towards certain neighbourhoods which, at times, can give rise to the impression of an "invasion". In the political sphere, the possibility of participation is limited, leading to the situation of "less rights", unless the host country's nationality is adopted, which in itself does not guarantee better integration. The right to culture receives less recognition, but nevertheless has a significant effect on integration. The main obstacles to integration are located in the labour market and in social discrimination. Lastly, reference is made to the situation of these immigrants in Spain.

Objective To determine the permeability of prolonium iodide through blood-ocular barrier.Methods The adult rabbits were divided into 4 groups randomly.In the group 1,every rabbit was injected 25mg/kg prolonium iodide with intramuscular injection;In the group 2,every rabbit was injected 0.4mL prolonium iodide with subcon junctive injection;In the group 3,every rabbit was injected 0.9% NaCl with intramuscular;In the group 4,every rabbit was injected 0.4mL 0.9 NaCl with subcon junctive.After injecting the prolonium iodide concentration was detected in different time by means of arsenic and cerium calalysis spectophotometry.Results The concetration in aqueous humor in the intramuscular and subcon junctive injection groups were higher then that in other groups.Conclusion Prolonium iodide could enter aqueous humor of rabbit through blood-ocular barrier.


It is shown, that directional freeze-drying is capable of forming dense and porous ceramic structures in one processing step. This promising technique makes for high porosities (up to 90%), the development of aligned pores and graded porosity while sintering shrinkage is reduced. Research on yttrium stabilized zirconia (YSZ) and subsequently fine copper particle systems, indicates that this method appears applicable to various material systems without major processing modifications. Graded functional ceramic and cermet layers, which are particularly important in porous anode-electrolyte assemblies in solid oxide fuel cells (SOFCs), could also be processed in one step using the freeze-drying approach. Scanning electron microscopy was used to study pore formation mechanisms and pore geometry. It could be shown, that the mechanism, which drives pore formation in directional freeze-drying, may result from convective motion of the water-based ceramic slurry at the onset of freezing


Neonatal jaundice affects approximately 60% of term and 80% of preterm infants within the first week of life. Gestationbased treatment threshold graphs by the National Institute of Health and Care Excellence are used to guide jaundice management in the UK. NICE treatment thresholds at 37week gestation are much lower compared with ≥38 weeks and also when compared with the previous and recently updated American Academy of Paediatrics guidelines. This results in an increased treatment burden and hospitalisation of 37week infants, including mother–baby separation. Infants born at 37 weeks usually are grouped with those born at ≥38 weeks for most neonatal pathologies under the label 'term infants'. Whether kernicterus develops at a lower serum bilirubin (SBR) level in 37week infants compared with those ≥38week has not been established. We aimed to ascertain the impact on admissions and medical interventions in jaundiced infants born at 37 weeks if they were managed based on ► NICE thresholds for ≥38 weeks. ► Previous AAP thresholds for 37 weeks (2004). ► Updated AAP thresholds for 37 weeks (2022). We retrospectively reviewed the electronic patient records of all infants born at 37 weeks with a birth weight of ≥2.5 kg who received treatment for jaundice at Birmingham Heartlands Hospital between April 2019 and March 2021. Their SBR levels were plotted on the ≥38week NICE and both 37week AAP charts.Infants with jaundice but with other principal diagnoses were excluded. We included 184 infants who had 188 episodes of inpatient phototherapy. The mean birth weight was 3128 g (SD±430 g), and the median age at admission was 36 hours (IQR 25–73 hours). While 23 (13%) infants were admitted to the neonatal unit (NNU) for jaundice close to exchange transfusion, 102 (55%) and 58 (32%) were admitted to the postnatal ward and transitional care, respectively. Their median duration of hospital stay was 45 hours (IQ 33–57 hours). Figure 1 shows the interventions received by infants admitted to NNU apart from phototherapy. None received exchange transfusion or developed kernicterus. Only 17 (9%) infants would have needed phototherapy if NICE ≥38week threshold was used (p<0.00001); 42 (23%) and 19 (10%) based on the previous (2004) and updated AAP (2022) guidance, respectively (p<0.00001) (table 1). As per AAP 2022 guidelines, 10 (5.4%) infants had hyperbilirubinaemia neurotoxicity risk factors; however, only five qualified for treatment when plotted on higherrisk AAP 2022 charts (table 1). In conclusion, applying AAP riskbased recommendations for 37week jaundiced infants or using NICE ≥38week charts could significantly decrease the treatment burden at this gestation. The updated (2022) AAP 37week treatment thresholds are quite similar to the ≥38week NICE but have lower thresholds for those with hyperbilirubinaemia neurotoxicity risk factors. NICE has already implemented measures for primary prevention (antenatal antibodies and blood group screening and Rhesus factor prophylaxis) and early postnatal care emphasising feeding support and close monitoring of jaundice. 4 5 Adoption of risk factorbased approach to jaundice management by NICE may safely minimise treatment burden not only for 37week infants but also across all gestational ages.


This paper tackles the mechanism of Iciotibial tract frication injury injury mechanism based on the study of the movement features, mechanical characteristics and anatomic analysis of the changes of the hip and knee in running and Jumping athletes' training, in the hope of providing advices for the prevention of injuries and for harmless training.


Evidence for position sensitivity in object‐selective visual areas has been building. On one hand, most of the relevant studies have utilized stimuli for which the areas are optimally selective and examine small sections of cortex. On the other hand, visual field maps established with nonspecific stimuli have been found in increasingly large areas of visual cortex, though generally not in areas primarily responsive to faces.


In 2021, the Centers for Medicare & Medicaid Services (CMS) began testing the value-based insurance design model in 9 Medicare Advantage organizations providing plansin206countiesnationwide.Underthismodel,which will become more widespread in the future (anticipated to increase to 15 Medicare Advantage organizations providingplansin461countiesin2022),1 hospiceservicesarepaid for and overseen by Medicare Advantage, unlike the existing structure that carves out hospice services from MedicareAdvantage.Inthecarve-outapproach,whenMedicare Advantage enrollees elect hospice, their hospice benefits are provided under traditional Medicare coverage and are not overseen by the Medicare Advantage plan. Proponents of the Medicare Advantage carve-in suggest it has the potential to reduce fragmentation, produce new opportunities for coordination, and create new programs for patients at the end of life by consolidating accountability under Medicare Advantage.2 However, older adults, and particularly those with serious illness, whose end-of-life experiences would be shaped by Medicare Advantage under the carve-in, may potentially be at risk to receive lower-quality care because of the incentives to control the costs of care in Medicare Advantage plans. This Viewpoint summarizes some of these concerns and outlines the possible implications of the Medicare Advantage hospice carve-in for end-of-life care if existing trends continue.


We present the design, fabrication and characterization of non-periodic multilayer mirrors for the compression of attosecond pulses in the XUV domain. We demonstrate that time domain optimization allows pulse compression down to sub-50 as duration.


The definition of "Divided" and "Undivided" claimed by Wang Guo-wei is actually a guide to the junior class of appreciation of literature works, whith is a kind of instinctive aesthetics. The major difference between "Divided" and "Undivided" is that whether one's works can highlight readers aesthetic happiness at the very beginning. Thus the happiness comes from a quick exchange and communication between the mood expressed by the poems and the feelings of the readers. Then the works with simplified words, understandable thesis, and fluent beats are certainly to achieve the goal, while complicated ones are impossible to do so. Therefore, the analysis between Shaoyou and Meicheng poems is to difine the more advanced one from this scant point.


Recombinant bovine somatotropin(rbST) administration to dairy cows increases milk production and improves the efficiency of milk synthesis, though management factors have been identified as major source of variation in dairy cows responses. Milk nutrient density is unaffected by rbST supplementation and no significant differences in milk composition between cows treated and not treated. The magnitude of reproductive responses of dairy cows to rbST is variable where there exists an increase in days to first estrus and twinning rates, increases days-open and services per conception. The use of rBST may have significant welfare consequences since unnaturally high milk yield production exist. This is reflected in different forms, among these, challenge of maintaining body condition of cows treated with rBST at the end of lactation, relative risk of mastitis due to increased milk yield and an increased incidence of lameness in cows. Reproductive problems in dairy cows have become very common as consequence of using rBST's, resulting with large numbers of cows being culled. rBST is biologically inactive in humans and its residues in food products have no physiological effect, but its injection to cow results in an increase in quantities of IGF-I and becomes one of the leading suspects involved in the development and spread of cancers. There is also suspect of increased human risk for development of anti microbial resistance in exposure to milk antibiotic residues from the use of rbST caused mastitis. This could be managed by practices in use by the dairy industry. The use of rbST reduces the resource used and environmental impact per unit of milk production. That is why increased animal performance is suggested as one of the most effective mitigation strategies to decrease greenhouse gas (GHG) and ammonia (NH3) emissions from livestock production per unit of product produced.


Active motion is a concept in complex systems theory and was successfully applied to various problems in nonlinear dynamics. Explicit studies for gravitational potentials were missing so far. We interpret the Friedmann equations with cosmological constant as a dynamical system, which can be made "active" in a straightforward way. These active Friedmann equations lead to a cyclic universe, which is shown numerically.


In this study, panel vector autoregression (PVAR) models are employed to examine the relationships between industrial production growth rate, consumer price inflation, short-term interest rates, stock returns and exchange rate volatility. More specifically, I explored the consequences of the dynamics detected by the models on monetary policy implementation for 10 OECD countries. This study indicates that factors that may cause a rise in short-term interest rates with respect to the USA can lead to volatility in exchange rates and thus macroeconomic instability. It is also implied that sustaining macroeco- nomic growth and decreasing inflation can result in increased export performance, which in turn provides the amount of US dollars to curb volatility in US dollar quotations. Accordingly, this study reveals that high importance should be given to both monetary and non-monetary factors in the open-economy framework to detect the possible impacts on trade and capital flows by dynamic stochastic general equilibrium (DSGE) models. Due to their exchange rate risk of economic agents, I also suggest that the economic pol- icy makers of these countries had better create a theoretical framework including finan cial frictions, economic agents' preferences and different shocks to smooth the variations in exchange rates and minimise the negative outcomes of Brexit.


ABSTRACT The last half-century has witnessed an astronomical rise in the number of tall building projects in urban centers globally. These projects however frequently experience delays and total abandonment due to economic reasons. This study presents the application of Machine Learning techniques in the systematic development of a model to estimate the preliminary cost of tall building projects. The techniques considered include Multi-Linear Regression Analysis (MLRA), k-Nearest Neighbors (KNN), Artificial Neural Networks (ANN), Support Vector Machines (SVM), and Multi Classifier Systems. Twelve models were developed and compared using standard performance metrics. The results revealed that the best performing model was based on a Multi Classifier System using KNN as the combining classifier, with a Correlation Coefficient (R2) of 0.81, Root Mean Squared Error (RMSE) of 6.09, and Mean Absolute Percentage Error (MAPE) of 80.95%. This research showed the potential of modern digital technologies such as machine learning to solve problems of the construction industry. The procedure described in this study is of significant value to research and practice in the development of preliminary cost estimation models. The developed model can function as a decision support tool in the preliminary cost estimation stage of tall building projects.


Abstract Development of three component skills in reading Chinese was examined in primary school children in Hong Kong. Feature analysis skills, syntax knowledge, and semantic analysis skills were found to differ in their contribution to reading proficiency at different grades. Visual processing skill was not at all a good predictor for reading proficiency, but the phonological access skill was important in predicting children's reading proficiency before grade three. It was an ineffective predictor beyond grade three. Skill in semantic analysis, on the other hand, was insignificant as a predictor at younger grades but it became an important predictor after grade two. Syntax knowledge was an important predictor of reading proficiency in the first grade and remained a significant predictor of reading proficiency right up to grade six. The present data support the idea that some preliminary component processes of reading may become automatic with increasing experience in reading and that this automatization...


The results of many measured engineering experiments require an analysis and study process in order to determine the relationships between the independent variables and the dependent variables, and accordingly, the accuracy of the values of the adopted variables becomes an urgent necessity. In this research paper we will take a sample of laboratory data and find the necessary relationships between the different variables, and then we will present some models of artificial neural networks to find solutions to these relationships in order to make the necessary comparisons to reach some of the necessary recommendations regarding the handling of measured data.


The industrial applications of lightweight metals is the driving force for engineers and researchers to find solutions with cost effective to improve the existing lightweight alloys with attractive mechanical properties and service performance levels. The Al-Mg-Si alloy is among those alloys gaining prominence by automotive industry, with an interest to reduce weight, fuel consumption and exhaust emissions of the vehicles. In previous investigations, the application of Taguchi design of experiments (DOE) of the L9 orthogonal array (OA) with four process variables, namely, quenching media, delay time before stretching, stretching steps, delay time after stretching and three levels for each variable has shown that the strength or ductility values is enhanced by applying DOE for single quality optimization. However, product performance depends on many quality characteristics, which cannot be solved by Taguchi method. Thus, the optimization of multi qualities (yield, tensile, ductility, tensile toughness) of the 6061 aluminum alloy can be resolved by Grey-based Taguchi method. The method combines the Taguchi DOE orthogonal array (OA) with grey relational analysis to find the grey relational grade, which can convert the optimization of multi qualities into single quality optimization that is used to determine the optimal variables levels and their effects on performance of the alloy. The obtained results shows that the most affected process variables to the tensile properties values is stretch steps, followed by quenching media and then delay times and thus the optimal process variable levels are determined more precisely on the overall tensile properties of the alloy.


Abstract A new species of the genus Araripesuchus from the Albian–Cenomanian locality of the El Chocón (Neuquén Province, Argentina) is described. The diagnosis of the genus is reviewed and its phylogenetic placement within Crocodylomorpha discussed. Araripesuchus is proposed here as being the sister taxon of Neosuchia, corroborating previous phylogenetic analysis. The new species, Araripesuchus patagonicus, differs from the type species, A. gomesii in the relationships of the prefronto-nasal and lachrymo-nasal sutures, the dermal placement of the postorbital bar on the medial side of the jugal, and the greater extension of the squamosals in the skull dorsum. The African species, "Araripesuchus" wegeneri, does not share the diagnostic traits of the genus, and its reassignment to a new genus needs to be considered. The phylogenetic context of Araripesuchus and "A." wegeneri permits a reanalysis of the role played by their amphiatlantic distribution in the Aptian-Albian. "Araripesuchus" wegeneri and the South American forms might share a pre-Aptian common ancestor, and have been already differentiated and isolated in the African and South American continents by the time of the Aptian–Albian.

The article is devoted to one of the Soviet State's policy directions at the first stage of its existence, aimed at the preservation of cultural values and the formation of museum art collections. The poorly studied question about the features of this policy implementation is revealed on the example of the TASSR (Kazan Province — before May 1920), where in the 1920s a whole network of museums was created; almost in each of them, an art department was organized. The appeal to this topic is relevant in connection with the opening of a large number of public and private museums, which face similar challenges, as well as the active scientific activities of museums to study their own collections, in the framework of creation of the State Catalogue of the Museum Fund of the Russian Federation. For the first time, the article introduces into scientific circulation a number of sources, on the basis of which the main directions of this activity, as well as the museums' art collections themselves, are analyzed. In the TASSR, the interaction with the State Museum Fund (SMF) was carried out by the Department for Museums and Protection of Monuments of Art, Antiquities and Nature, employees of which (P.M. Dulsky and P.E. Kornilov) were engaged not only in organization of the artworks' transferring to museums, but also in their selection. The article states that, thanks to the SMF, the Central Museum of the TASSR had the most complete and valuable art collection, and an interesting collection was formed in the Kozmodemyansky District Museum, which was part of the Kazan Province until 1920. This study shows that the SMF was an important and effective mechanism for the implementation of state policy in the field of culture: its activities contributed to the creation of provincial museums' collections, based on scientific principles and aimed at presenting the history of fine arts development.


Pulvilloric acid, from P. pulvillorum, is shown to have the quinone methide structure (4,6-dihydro-8-hydroxy-6-oxo-3-n-pentyl-3H-2-benzopyran-7-carboxylic acid). Hydrogenation of pulvilloric acid is accompanied by aromatisation of the nucleus, giving dihydropulvilloric acid which, on esterification and methylation, yields methyl di-O-methyldihydropulvillorate. Partial oxidation of the latter compound furnishes a lactone (methyl 3,4-dihydro-6,8-dimethoxy-1-oxo-3-n-pentyl-1H-2-benzopyran-7-carboxylate), while permanganate oxidation gives 3,5-dimethoxy-4-methoxycarbonylphthalic acid. On being boiled with aqueous sodium hydroxide, pulvilloric acid is degraded to 1-(3,5-dihydroxyphenyl)heptan-2-ol, the structure of which is established by reduction to 5-n-heptylresorcinol.


PurposeThe importance of workers in labour-intensive industries, such as tourism, is undeniable. In this sense, it has been investigated for decades from various methodological approaches. However, in the academic literature on tourism, the partial least squares-structural equation modelling (PLS-SEM) technique has hardly been used.Design/methodology/approachTherefore, this work uses that technique to contrast which factors define the employees' wages in the Spanish tourism industry. Additionally, an importance-performance map analysis (IPMA) analysis is carried out, which provides informed decision-making.FindingsThus, the main results obtained are the verification and measurement of the relationships of Human Capital, Labour Conditions and Market with Wages, and the relation between Human Capital and Labour Conditions. Besides, the improvement points in each variable are identified. Especial emphasis is given to those related to Human Capital and, partially, to the Market.Research limitations/implicationsHowever, there are certain limitations to this study. Mainly, as the indicators used are given by the 2018 Salary Structure Survey, they are stiff and so the design of the model turns to be more difficult.Originality/valueConsidering the turning point that the temporary cessation of the tourism industry activity due to the COVID-19 pandemic has been, it is essential to take advantage of it to identify and correct existing deficiencies. Therefore, this work aims to be a base document for the identification of these problems.


Architecture design is the top-level design of the Internet of Things (IoT). Based on the conceptual model of IoT, its reference architecture based on six-domain model is defined in international standards. It is necessary to establish the system architecture for smart farm suitable for international standards. Through the comprehensive analysis of the agricultural production and management process and the in-depth study of the international standards for the IoT reference architecture, the entity integration of user domain, physical entity domain, sensing & controlling domain, application & service domain, operations & management domain and resource access & interchange domain of the smart farm are determined. The six-domain model reference architecture of smart farm is proposed. There are advantages of compatibility, flexibility and scalability, etc. As an example, it is applied in the system architecture design for the open field vegetable smart planting subsystem. It can provide effective, reliable and scalable framework design guidance for each subsystem of smart farm. It is conducive to the formation of a collaborative ecosystem of smart farm, so as to realize its large-scale applications.


Full waveform inversion (FWI) is a non-linear, ill-posed, local data fitting technique. FWI looks to moves from an initial, low-wavenumber representation of the earth parameters to a broadband representation. During this iterative process a number of undesirable artifacts can map into our model parameter reconstruction. To mitigate these artifacts and to ensure a geologically consistent model parameter reconstruction, various preconditioning and/or regularization strategies have been proposed.This thesis details the construction of new, efficient, multi-dimensional, structurally-orientated wavenumber filters. A preconditioning strategy has been devised using these filters that we have successfully applied to FWI. The 1D analytical inverse Laplacian covariance operator (Tarantola, 2005) forms the basis of higher dimensional operators and is initially validated by comparing to the 1D analytical Laplacian covariance operator. We use this analytical 1D inverse function as the basis for higher dimensional filtering via the addition of multiple, orthogonally orientated inverse functions. These additive inverse laplacian functions (AIL) are shown in 2D and 3D configurations and are discretized using finite-difference techniques. We show that one can calculate, a rapid and robust wavenumber filter, by solving the linear system associated with these inverse operators. When dip is included at the finite difference discretization stage, it is possible to use these operators as highly efficient, structurally orientated wavenumber filters.The AIL filter is shown to be rapid to converge and its performance is independent of the vector to be filtered. We show, that the filter can be a useful preconditioning operator for the FWI gradient. Preconditioning the gradient can mitigate against ill-posed effects mapping into the model-space. Two synthetic (Valhall and Marmousi) frequency domain FWI example are shown in this thesis. The AIL preconditioner has success at mitigating the ill-posed imprint coming from ambient noise in the observed data and also artifacts from spatial aliasing effects in the FWI imaging condition. The ability to include dip, allows one to preferentially filter along geological dip. This filtering strategy allows the mitigation of artifacts, while simultaneously preserving the stratigraphic based wavenumber content that is orthogonal to dip.A 2D, real data FWI case-study is also shown and we highlight the sensitivity of the inversion result to the initial model. The initial model is of key importance, this especially true in the areas deeper than the maximum penetration of transmitted waves. The application of FWI on this line is able to significantly improve gather alignment on a RTM, migrated image. We also see that the AIL preconditioner can allows us to significantly decrease the number of shot records we are required to model in our inversion workflow without degrading the key geological wavenumber content in the final inversion result.


Nowadays, an understanding of its own business processes is crucial for companies, to ensure an efficient and quick changing work flow. While several tools exists using graphical annotations, e.g. Business Process Model and
Annotation (BPMN), an untrained staff member may not be able to understand business processes described in these annotations, resulting in additional investments into staff
member training. Furthermore, some structures used in graphical annotations may not seem native to untrained users, causing misinterpretations of business process models. Fostering this issue, natural language-based process descriptions may used. These descriptions are automatic-generated from process models. Another problem of modern business process modeling is the communication between process modelers and domain experts. A thought of a domain expert can be misinterpreted by the process modeler. The results are discrepancies in business process models. Avoiding this problem, modeling mechanics for natural language-based process descriptions may used.
Therefore, the thesis introduces fundamentals of the proView project as well as the generation and editing of natural language-based process descriptions. Subsequently,
integration steps of natural language into the proView project, divided into two parts, are shown. The first part contains integration of a process model to natural language text converter. The second part discusses problems and solutions of natural language-based modeling. Further, the second part shows the integration of natural language-based
modeling into the proView project. Finally, further steps in the future are discussed.


The 1 5 1Eu and 57Fe resonances have been used to study magnetic exchange interactions in the orthorhombic perovskite solid solution EuFe1 –xCoxO3(O < x < 1). The replacement of a neighbouring Fe3+ ion by diamagnetic Co3+ ion results in a reduction in the flux density of the supertransferred hyperfine field at the 57Fe nucleus of 1.02 ± 0.05 T extrapolated to 0 K. The 1 5 1Eu resonance is considerably broadened by substitution; this effect is proved to be of magnetic origin, and a detailed model is proposed which explains the data quantitatively. The flux density of the molecular exchange field at the 1 5 1Eu nucleus when a neighbouring Fe3+ atom is substituted by Co3+ is expressed by the exchange constant (β/k)Bom(0)= 3.2 ± 0.1 K.


Propulsion shafting systems having two or more prime movers connected in a single shaft for propulsion power have operating advantage compared with other propulsion shafting designs. This includes by being able to distribute power more efficiently and in cases of emergencies such as one prime mover breakdown, the vessel can still navigate safely. Taking into account installation space, this propulsion shafting system is primarily applied on special purpose vessels and in some motor craft. Flexible coupling are normally employed to dissipate unwanted resonances and shaft misalignment. As such, the flexible coupling dynamic behavior must be verified during operation to ensure function and reliability. In this paper, a flexible coupling model was applied on a fishery inspection vessel with a twin-engine single-propeller propulsion system to confirm its dynamic behavior and the results are presented herein.

Abstract Attempts have been made to improve the communicative abilities of severely impaired aphasics by teaching them a non-verbal communication system. The results from studies in which aphasics were trained to use alternative symbol systems have not been too encouraging. The possibility of teaching aphasic patients to communicate with the aid of pictographs has remained unexplored. A therapy programme aimed at training aphasic patients with little or no usable speech to convey messages pictorially is introduced. The programme proceeds from the receptive and expressive use of pictographs encountered in everyday life to the spontaneous production of line-drawings in response to questions.


Significant increases in the serum erythropoietin of male rats occur after the end of a brief hypoxic exposure. These increases in the hormone are almost completely abolished when the kidneys are removed after the hypoxic exposure. Injection of puromycin or cycloheximide after the hypoxic exposure significantly decreases the subsequent increases in serum erythropoietin titers, whereas injections of actinomycin D at this time have no significant effect on erythropoietin levels. Injections of actinomycin D before the hypoxic exposure prevent the increase in serum erythropoietin that normally occurs. These findings suggest that a brief period of hypoxia initiates a DNA-dependent RNA synthesis that regulates the de novo ribosomal synthesis of protein(s) involved in the biogenesis of erythropoietin and that the kidney is essential for these reactions to occur.

Non-stationary random vibration of 3-D train-bridge time-dependent systems subjected to the action of non-uniform lateral horizontal earthquake is investigated on the basis of the pseudo-excitation method(PEM).The motion equation of train-bridge time-dependent systems due to multi-point earthquake excitations with the consideration of wave travelling effect is established by connecting the motion equations of the train and bridge through wheel-rail contact relations.The excitation of lateral horizontal earthquake is assumed to be a uniformly modulated multi-point different-phase completely coherent random excitation,while the excitations of track irregularity are assumed to be multi-phase different-phase completely coherent random excitations.The pseudo-excitation method(PEM) is extended to such time-dependent systems and is applied to transform the above random excitations into a series of deterministic pseudo excitations.After solving the correspondent pseudo responses by using the Newmark method,various non-stationary random responses including the time-dependent PSD and RMS of interested quantities can be obtained easily.Numerical examples show the effectiveness and accuracy of the presented method by comparison with Monte Carlo simulation.Additionally,the influences of seismic apparent wave velocity and site type on system random responses are discussed.


This investigation is a study of the principles and practices embodied in the Trade Agreements policy inaugurated by the United States in 1934 as it relates to Latin American trade.


In this study, we aim to understand midwife leaders' perspectives on continuing professional education among midwives in their work unit. We used a phenomenological perspective and method in the process of interviewing the participants and analyzing the data. Five midwife leaders who worked in large maternity wards and had considerable experience as managers were recruited. Results revealed three essential constituents: (a) constraints and the individualization of continuing professional education, (b) normal and at-risk births: fluid boundaries and moving targets, and (c) a personal approach: dimensions of control and trust-driven leadership. We discuss these findings in relation to current research and perspectives on how professional cultures and leadership impact continuing professional education and knowledge management, revealing possible implications to further promote professional development in public health organizations. We conclude that midwife leaders' views on continuing professional education as practical skills training may hinder professional communication and knowledge development in maternity care.

Abstract This paper reports on the composition of aroma compounds during blood orange maturity. Volatile compounds have been analyzed by gas chromatography. Terpenic fraction constitutes 94% of total aroma compounds of blood orange; limonene is the major monoterpenic hydrocarbon of this fraction, constituting 81% and 73% of total aroma.


A chimeric receptor with an alpha7 nicotinic receptor extracellular segment & serotonin type 3A receptor transmembrane (TM) & cytosolic (CY) segments, when transiently transfected into human tsA201 cells, is highly palmitoylated, which appears to promote cell‐surface & functional expression (Drisdel et al. 2004). The TM & CY segments contain 5 potential palmitoylation sites: C231 & C278 in TM domains M1 and M3, respectively, & C322, C344 & C357 in the M3–M4 CY loop. Cys‐to‐ala mutants were transiently expressed in tsA201 cells & the number of surface & intracellular receptors & surface receptor function were assessed. Surface expression of receptors with the double TM segment mutation C231A/C278A was only 48% that of wild‐type (WT) receptors (p=0.01), while expression of receptors with the triple CY loop mutation C322A/C344A/C357A did not differ significantly from WT. Expression of C278A was 81% of WT (p=0.02) while expression of C231A did not differ significantly from WT. Mutants C278A/C322A/C344A/C357A & C231A/C278A/C322A/C344A/C357A both showed significantly lower surface expression than WT (47%, p=0.005 & 29%, p=0.05, respectively). The amount of intracellular receptors produced in cells transfected with the above TM segment mutants did not differ significantly from that of WT, suggesting that removal of sulfhydryl groups in the TM segments interfered with the trafficking of fully‐assembled receptors to the cell surface. Cells expressing the 5‐cysteine mutant receptor accumulated 2‐fold higher intracellular calcium levels than cells expressing WT (p<0.001).

Purpose To investigate the techniques of multi-slice computed tomography (MSCT) coronary angiography. Materials and Methods Fifty patients with suspected coronary heart disease (CHD) underwent MSCT coronary angiography, to analysis the factors influencing the coronary artery imaging quality, including the selection of beating cycle in retrospective ECG-gated reconstruction, heart rate and the different reconstructive method. Results The optimal image reconstruction windon of cardiac cycle was at 70 %. Transverse scanning was the essential method to display images. MIP, RT3D may have the great potential role and MRP, VE may be a complementary method. Images obtained with heart rate not more than 70 bpm showed less artifacts. Motion artifacts in the distal part of the LCX significantly increased at higher rates. Conclusion MSCT has a great potential role in evaluating coronary arteries and has great value as a noninvasive method.


The invention belongs to the technical field of hot melt adhesive and particularly relates to a reinforced heat-shrinkable tube hot melt adhesive and a preparation method thereof. The first technical problem to be solved by the invention is to provide the reinforced heat-shrinkable tube hot melt adhesive, which has remarkable sealing and anticorrosion effects. The reinforced heat-shrinkable tube hot melt adhesive disclosed by the invention comprises the following components in part by weight: 20 to 50 parts of terpene resin, 35 to 75 parts of ethylene-vinyl acetate (EVA), 0 to 6 parts of antioxygen and 3 to 20 parts of filler. The reinforced heat-shrinkable tube hot melt adhesive disclosed by the invention has high temperature resistance and high stripping strength, the polyethylene (PE) to PE stripping strength is more than 182N/cm, and the PE to epoxy primer stripping strength is more than 205N/cm. Thus, the adhesive can meet the sealing and anticorrosion requirements of thermal-insulation pipes for oil and natural gas.

The hard real-time schedulability of dependent task-graphs is studied for single bus homogeneous multiprocessor systems. A model which includes interrupts and context switching as well as bus contention is developed. The model captures real-time operating system effects aimed at realistically modeling both intra-processor and inter-processor communications. A robust scheduler is used to assess the impact of interrupt service time (IST) and context switching time (CST) on schedulability. For the class of task-graphs studied, it is shown that schedulability is a nonlinear function of only the weighted sum of IST and CST.


The purpose of this paper is to describe a new approach in road detection. This research uses two detection processes approaches: RGB histogram Filterization and Boundary Classifer, which is different from previous works on road detection. RGB Histogram Filterization processes the reading from the camera in greyscale form and afterward processes them by color segmentation. The last step for this process is determining area between the slopes, which is considered to be the road area. Boundary classification process then employs the RGB indexing on slope ranges, and mapping them into real pictures of roads and its environments. The next process is specifically looking for line boundaries by using Hough-Transform and Canny Edge Detection, and transforms them into binary numbers of `0' and `1'. `1' represents road boundaries while `0' represents surrounding area. The coordinate of `1', then mapped by cubic spline to produce connecting line between point `1' coordinates, which in the end produce sharp images on boundaries between road and non-road. This model has proven to be able to detect road conditions and distinguish roads from non-road in a precise way. A test is already conducted for the system by using real-time roads in Bandung, Indonesia. The results are really promising for the road condition on both straight and curved road area.


To better understand the space-time dynamics and the effect of urban growth on the transformation of territory, this article presents the results of Iber 2D simulation tests to analyze flood events in the lower Sabinal river basin, Tuxtla Gutiérrez, Chiapas, Mexico. First, Landsat 5 and Landsat 8 satellite images from 1986 and 2014 years were processed to generate classified images of the land cover of the study area. From the identified coverages, the soil roughness values were defined, as well as the infiltration parameter of water in the soil. Both values were used as input data in an Iber 2D simulation model to analyze and compare the maximum flood level with different precipitation values in the two reference years. Between 1986 and 2014, the coverage of urbanizations increased considerably, while the coverage of trees, pastures and agriculture decreased. Due to this change in coverages, in 2014 rainfall caused higher values of direct runoff, increasing water heights levels and therefore the risk of overflowing the Sabinal River. With the model shown here, it is possible to calculate the depth and water heights reached and identify the points and moments of overflow of the river. This model can be used to provide feedback to flood risk warning systems and to analyze basins that lack monitoring infrastructure.


who had been diagnosed with diabetes at 19 years of age (BMI 18.3 kg/m 2 ) (Fig. LA). This mutation causes a frameshift and the generation of a mutant truncated protein of 264 amino acids that lacks the transcription activation domain. Screening other family members showed that the mutation was also present in the proband's sister (IV-3), who had been diagnosed with glycosuria at 14 years of age during the course of an annual school physical examination. The mutation was also found in the proband's father (III-2), who had been diagnosed with diabetes at 61 years of age. The two affected sisters (IV-2 and IV-3) are currently being treated with 10-20 U of insulin, and their father with diet. Medical records indicate that the paternal grandmother (D-2) had early-onset diabetes, and so also may have inherited the mutation. The frequency of HNF-1(3 gene mutations in our study population of Japanese subjects who have early-onset type 2 diabetes with a first-degree relative with diabetes is 2.5%. Together with the previous observation by Horikawa et al. (10), our results indicate that mutations in the HNF-ip gene are not a major cause of early-onset type 2 diabetes in Japanese, although the results apply only to the coding region of the HNF-1(3 gene. The proband and her sister had decreased renal function (creatinine clearance <50 ml/min) and multiple bilateral renal cysts with three to five cysts per kidney (0.3-1.2 cm in diameter) (Fig. IE). Their father also had chronic renal failure with renal cysts, which is now being treated by hemodialysis. While the two affected sisters showed no evidence of proteinuria, the father had persistent mild proteinuria (<300 mg/day), which was first noticed during the course of an annual health examination 20 years before the diagnosis of diabetes. The A263fsinsGG mutation was also found in the nondiabetic 2-year-old son (V-l) of the proband and the 5-year-old daughter (V-2) of the affected sister, who also had elevated levels of serum creatinine (1.3-1.8 mg/dl; normal 0.6-1.0 mg/dl) at birth. Moreover, subject V-l was found at birth to have bilateral renal cysts measuring several millimeters in diameter, and fetal ultrasound examination at 27 weeks of gestation revealed renal abnormalities, including bilateral enlarged kidney mass and multiple parenchymal hyperechoic nodules (Fig. LET). These observations suggest that the A263fsinsGG mutation in the HNF-ip gene might be associated with diabetes and renal dysfunction in this family. Renal dysfunction described in this report is defined broadly, including proteinuria, decreased renal function, and renal cysts. Moreover, these abnormalities appear to precede the onset of dia


Rosa laevigata Michx. a special fruit in Guizhou, was used to produce brandy. The producing procedures included freezing and juicing,hydrolysis and impregnation, yeast strain activation, sterilization, composition adjustment, fermentation, distillation, aging, filtration, and bottling.The best fermenting conditions were summed up as follows: the use level of yeast was 0.4 %, fermenting temperature was at 20 ℃, and fermenting time was 7 d. In order to keep the special flavoring compositions of Rosa laevigata Michx. in brandy as possible, alcohol content was enhanced to 38 %vol~44 %vol and fermenting period was shortened to 4~6 months. The produced brandy had natural and pleasant color, enjoyable taste, and harmonious flavor of Rosa laevigata Michx. Total non-alcoholic volatiles content in the produced brandy was 2.129 g/L, just between super(XO) and quality brandy.

The checkpointing problem in embedded real-time systems is dealt with from a reliability point of view. Transient faults are assumed to be detected periodically. The probability of successful real-time task completion in the presence of transient faults is derived with the consideration of the effects of the transient faults that may occur during checkpointing or recovery operations. Based on this, some conditions under which inserting checkpoints works positively are introduced.


Block Truncation Coding (BTC) is a lossy data compression technique used for compression of images. BTC is a simple and fast image compression algorithm with less computational complexity than former schemes proposed. In this paper we propose a modified three-level BTC with an improved compression factor. Experimental results show that the suggested image compression methodology yields an image with better quality, low bit rate and lower computational complexity than the conventional three-level BTC.


The Flight Operations Risk Assessment System (FORAS) is a risk modeling methodology which represents risk factors and their interrelationships as a fuzzy expert system. The FORAS process systematizes the process of eliciting human expertise, provides for a natural representation of the knowledge in an expert system, and automates the process of risk assessment. There are many challenges in developing such a system. These include the selection of relevant subject matter experts, the combination and reconciliation of multiple, subjective knowledge bases, and the representation of knowledge in a model easily expressed, evaluated, and revised. This paper will present the technical background of the FORAS methodology, and demonstrate its implementation, as performed on its first operational partner, EVA Airways, of Taiwan.


ABSTRACT Since 9/11, Iranian Americans have challenged their racialization as troublesome terrorists through cultural productions that emphasize how they belong in a multicultural America. In this paper, I argue that these Iranian Americans perform "Persian/American exceptionalism," a representational strategy that embraces capitalist conspicuous consumption and touts universalist notions of freedom. In so doing, they attempt to erase post-revolutionary Iran and its association with political Islam from the U.S. imaginary as part of an effort to distance themselves from two major flashpoints in U.S.-Middle Eastern history – the Iran Hostage Crisis and September 11th.


System of systems involves several secondary systems working together with its creation gathering the knowledge of several distinct disciplines and teams, each one with their own background and methods, leading to a difficult communication between them. SysML, a language originated from UML, enables that communication, without background interference, with the use of a rich notation for systems design. This paper analyzes its use through the experience gained in the design of a chemical system with SysML.

It will store medication information on the server that the patient can see at any time. After using this device patient medication forgotten rate is reduced and the habit of the patient is significantly improved.


Torsten Pettersson, All Is But Fragments Devoid of Meaning? Semantic Oscillations in Three Poems by Hugo von Hofmannsthal. This article studies three poems by Hugo von Hofmannsthal (1874–1929), but it has two further objectives: to describe the workings of a poetic technique termed "semantic oscillations" and to exemplify a literary reaction to secularization. The first nineteen lines of "Ballade des auseren Lebens" (1895) exhibit a tension or micro-oscillation between the desperate nihilism of a meaningless, fragmented world and the consolatory pleasure of the exquisite phrasing. The depressive world view then swings over to a will to live but a further swing back is introduced by the emptiness suggested by "hohl" in the last line. In "Ein Traum von groser Magie" (1895) there are multiple semantic oscillations: the Magician is described as God, as Goethe, as a Dionysian dreamer, and as a man endowed with the gift of fantasy; "unser Geist" is seen as a personal daimon and as a God common to all; the dream is presented as true and as a hallucinatory projection; and the speaker in the final section of the poem as both reliable and unreliable. The world of "Vor Tag" (1907) is fragmented and filled with anguish. The human mind forges links between phenomena and endows them with meaning, but this is revealed as gratuitous projection. The religious mini-narrative about the suffering of Christ is similarly presented as a projection – but equally as a true story determining the nature of the cosmos. Between these opposite perceptions the reader is left to oscillate. Faced with these oscillations in the three poems, scholars have often reduced the meaning of the poems to one of the opposite poles in an attempt to render a unitary meaning. However, all disparate elements of meaning and the oscillation between them are essential to a complex poetic vision which offers solace in a fragmented and meaningless world, while concomitantly suggesting that this solace is an illusory projection. As well as adumbrating the splintered forms of modernism, the technique of semantic oscillations thus adequately embodies fragmentation and lack of meaning as a problematic kernel of secularized modernity


: This study presents a novel design of the three-layer winding coil sets of a coreless axial-flux permanent-magnet generator applied to small wind turbines. The proposed generator design consists of two rotors and an integrated stator with flattened winding coil sets of three-phase three layers connected using a wye configuration. An analytical model of the inductance and resistance of the coil set is described to analyse the influence of the coil shape variation due to winding imperfection. The air gap magnetic flux distribution analysis shows the advantage of the integrated flatten coil sets compared with a typical stack up three layers stator. An experimental design is conducted for the parameter design of geometric variables to optimise the output power of the proposed axial-flux permanent-magnet design. A prototype generator is then constructed to compare with a benchmark generator that has a rated output power of 300 W at 800 rpm. The proposed design outperforms the benchmark generator by 26.5% in terms of generated power at a typical driving rotation velocity of 500 rpm for a small wind turbine, and demonstrates a superior performance at a lower driving speed range, which is particularly important in a small wind turbine application.

Internet of things is an accumulation of physical objects which are able to send information over the network. Nowaday, an association utilizes IoT devices to gather real time and continuous data from sensors. This information can be utilized to enhance the customer satisfaction and to make better business decisions. The cloud has various advantages over on-premises storage for storing IoT information. But there are apprehensions with using the cloud for IoT data storage. The real one is security. To exchange the information over the cloud IoT devices utilizes WiFi technology. However, it has a few limits that confine the potential outcomes of the Internet of Things. On the off chance that more devices or clients that will be associated with the internet utilizing WiFi, the transfer speed gets separated among the clients hence the outcome will be slower network. Consequently, there is a necessity of a speedier and a solid internet administration to the Internet of Things to be completely operational. This paper shows the strategy which permits exchanging gathered loT information over the cloud safely utilizing LiFi innovation by applying role based access control approaches and the cryptography techniques.
