Mobile Augmented Reality (MAR) applications enable users to interact with physical environments through overlaying digital information on top of camera views. Detecting and classifying complex objects in the real world presents a critical challenge to enable immersive user experiences in MAR applications. Aiming to provide continuous MAR experiences, we address a key challenge of continuous object recognition, which requires accommodating an increasing number of recognition requests on different types of images in MAR systems and possible new types of images in emerging applications. Inspired by the latest advance in continual learning approaches in computer vision, this paper presents a novel MAR system to enhance its scalability with continual learning in realistic scenarios. Our experiments demonstrate that 1) the system enables efficiently recognising objects without requiring retraining from scratch; and 2) edge computing further reduces latency for continual object recognition.


In the process of expressway construction,a few cracks appeared on the surface of the completed pipe before opening to traffic.In the light of the cracked pipe culverts in Laoyemiao-Jining Expressway in Inner Mongolia,various factors causing cracking of culverts are discussed in this paper through the theoretical analysis with the application of large universal software,ANSYS 8.0,for finite element calculation.The results have shown that the main factors causing cracks of pipe culverts are in the improper construction method and the shrinkage of concrete.


Objective To establish a method for the determination of paeoniflorin and licorice glycoside in Weiling granules by HPLC.Methods The determination was carried out on a Hypersil ODS2(5 μm,4.6 mm×200 mm) column with a mobile phase of acetonitrile-0.1% phosphoric acid solution(14∶86).The detective wavelength was set at 237 nm and the flow rate was 1.0 mL·min-1.Results The linear range of paeoniflorin and licorice were 0.114 0-0.570 0 μg(r=0.999 3)and 0.211 4-1.057 0 μg(r=0.999 5).The average recovery rations of paeoniflorin and licorice were 98.6% and 98.2%,RSD were 0.7% and 1.1%.Conclusion This method is simple,accurate and reproducible,suitable for quality control of the drug.


Due to recent developments in emerging memory technologies such as MRAM/RRAM, resistive crossbar arrays have gained increasing importance. The size of the crossbar arrays is, however, limited due to challenges brought by the interconnect resistance, sneak path currents, and the physical area of the peripheral circuitry. In this paper, three figures of merit that characterize the limitations of resistive crossbar arrays with select ors, the driver resistance, voltage degradation across the cell, and read margin, are discussed. Models are described that exhibit good agreement with SPICE, exhibiting a maximum error of 6.5% for the worst case voltage degradation during a write operation and 6% during a read operation for voltage ratios above, respectively, 0.5 and 0.25. Furthermore, these models are used to predict device requirements of resistive crossbar arrays with selectors and to project parameter values such as the nonlinearity factor, resistance in the on state, and tolerable interconnect resistance per cell for large scale crossbar arrays.


The invention relates to a preparation method of L-carnosine zinc, which belongs to the technical field of preparation of pharmaceutical intermediates. The preparation method comprises the steps of dissolving L-carnosine in water for forming water solution of the L-carnosine, leading the water solution of the L-carnosine to be reacted with ion exchange resin for absorbing the L-carnosine on the resin for activation, adopting the water solution of zinc salt for eluting the resin absorbed with the L-carnosine, combining zinc ions in eluent with the activated L-carnosine molecules for forming L-carnosine zinc, precipitating from the water and carrying out solid-liquid separation on the eluent, thereby obtaining the L-carnosine zinc. The preparation method has the advantages that the technicalscheme for preparing the L-carnosine zinc has good yield, the zinc content in a product is not less than 22.0%, the optical rotation is not less than plus 8.0 degrees, and the quality is stable; andthe technical scheme does not use an organic solvent, the used ion exchange resin is recycled, and the main raw material of the L-carnosine is completely reacted, thereby improving the utilization rate of raw materials, reducing the preparation cost and meeting the industrial production requirements.


This paper aims to develop a methodology to retrieve images based on fuzzy dominant colors expressed through linguistic descriptions. This process involves two steps: assigning fuzzy colorimetric profile to the image and processing the user query. People regard color as an aesthetic issue, especially when it comes to choosing the colors for their clothing, apartment design and other objects around. It is often quite difficult to label these colors exactly using finite set of categories. Fuzzy color model that we are proposing represents the collection of fuzzy sets providing the conceptual quantization of crisp HSI space having soft boundaries. Most online shops tend to use conventional tag-based image retrieval systems. Making use of color visual content is still not disseminated in e-commerce. Subjectivity and sensitivity of humans in color perception and bridging the semantic gap between low-level visual features and high-level concepts are major issues that we plan to tackle in this research.


Using some basic knowledge of symmetric polynomial, number theory, combination formula, this article gives the new proof of the irreducibility of cyclotomic polynomial over Q, avoiding adopting the conclusion that is the only factorization.


Yarn hairiness has remained an issue of enormous interest in the field of yarn spinning research, since it directly affects yarn quality. In this work, a new method for the reduction of yarn hairiness is presented by attaching a simple effective air suction system to the web detaching zone of a conventional carding machine immediately behind crushing rollers. The slivers produced were almost free from dust or short loose fibers. Yarn properties such as hairiness, tenacity, elongation at break and evenness were evaluated. The ring-spun yarn that was produced was called Vacuum Cleaned Carded yarn or VCC yarn, due to the removal of the short fibers by air suction. The properties of VCC yarns were compared with those of conventionally produced reference yarn sample. Comparison of the results showed that the hairiness of optimum VCC yarn decreases by approximately 20%, while its tenacity, elongation at break and evenness were significantly improved. It was also found that the VCC yarn exhibited better spinning stability and was more environmentally friendly than the reference yarn.


This paper focuses on the structural and physical properties of Heusler compounds and alloys for spintronic and thermoelectric applications. Heusler compounds are a significant class of intermetallic materials with 1:1:1 or 2:1:1 composition comprising more than 1500 members. They are still a field of active research after more than a century of their discovery. New properties and potential fields of applications emerge constantly; the prediction of topological insulators is the most recent example. The properties of many Heusler compounds can easily be predicted by the valence electron count. Their flexible electronic structure offers a toolbox which allows the realization of demanded functionalities within one ternary compound. Devices based on multifunctional properties, i.e. the combination of two or more functions such as superconductivity and topological edge states will revolutionize technological applications. Thus, great interest has been attracted in the fields of thermoelectrics and spintronics research. The wide range of their multifunctional properties is also reflected in extraordinary magneto-optical, magnetoelectronic, and magnetocaloric properties. Here, we give a comprehensive overview and a prospective on the magnetic properties of Heusler materials.


Deciphering the Maya writing is an ongoing process that has already started in the early 19th century. Among the reasons why Maya hieroglyphic script and language are still undeciphered are inexpertly-created drawings of Maya writing systems resulting in a large number of misinterpretations concerning the contents of these glyphs. As a consequence, the decipherment of Maya writing systems has experienced several setbacks. Modern research in the domain of cultural heritage requires a maximum amount of precision in capturing and analyzing artifacts so that scholars can work on preferably unmodified data as much as possible. This work presents an approach to visualize similar Maya glyphs and parts thereof and enable discovering novel connections between glyphs based on a machine learning pipeline. The algorithm is demonstrated on 3D scans from sculptured monuments, which have been filtered using a Multiscale Integral Invariant Filter (MSII) and then projected as a 2D image. Maya glyphs are segmented from 2D images using projection profiles to generate a grid of columns and rows. Then, the glyphs themselves are segmented using the random walker approach, where background and foreground is separated based on the surface curvature of the original 3D surface. The retrieved subglyphs are first clustered by their sizes into a set of common sizes. For each glyph a feature vector based on Histogram of Gradients (HOG) is computed and used for a subsequent hierarchical clustering. The resultant clusters of glyph parts are used to discover and visualize connections between glyphs using a force directed network layout.

Social networks are frequently polluted by rumors, which can be detected by advanced models such as graph neural networks. However, the models are vulnerable to attacks, and discovering and understanding the vulnerabilities is critical to robust rumor detection. To discover subtle vulnerabilities, we design a attacking algorithm based on reinforcement learning to camouflage rumors against black-box detectors. We address exponentially large state spaces, high-order graph dependencies, and ranking dependencies, which are unique to the problem setting but fundamentally challenging for the state-of-the-art end-to-end approaches. We design domain-specific features that have causal effect on the reward, so that even a linear policy can arrive at powerful attacks with additional interpretability. To speed up policy optimization, we devise: (i) a credit assignment method that proportionally decomposes delayed and aggregated rewards to atomic attacking actions for enhance feature-reward associations; (ii) a time-dependent control variate to reduce prediction variance due to large state-action spaces and long attack horizon, based on reward variance analysis and a Bayesian analysis of the prediction distribution. On two real world datasets of rumor detection tasks, we demonstrate: (i) the effectiveness of the learned attacking policy on a wide spectrum of target models compared to both rule-based and end-to-end attacking approaches; (ii) the usefulness of the proposed credit assignment strategy and variance reduction components; (iii) the interpretability of the attacking policy.


A series of brake friction tests on a fibre reinforced composite brake pad and a HZ408 brake pad materials rubbing against a brake disc material were carried out on a friction and wear tester of MM-1000 type.During the test,the coefficient of friction,temperature increment and wear mass loss of both materials were measured.The worn surface morphologies were observed using a Confocal Laser Scanning Microscope(CLSM).The initial brake speed had a smaller influence on the friction coefficient of the fibre reinforced composite than it exerted the influence on that of the HZ408 brake pad.The fibre reinforced composite exhibited a larger averaged friction coefficient than the HZ408 brake pad did at a high speed.The wear mass loss of the fibre reinforced composite was found to be slightly larger than that of the HZ408 brake pad.At a low speed,the temperature increments of both pad materials were close to each other.At a high speed,the temperature increment of the fibre reinforced composite was found to be slightly larger than that of the HZ408 brake pad.


This research aimed to experimentally study the anchorage behavior of headed reinforcement in lap splices. Observations of cracking behavior, strain measurements of reinforcement, and strength are reported. The behavior of unconfined laps is compared to confined laps, and the behavior of nonheaded and headed bar laps are also compared. Bar stresses are compared with a proposed model for bearing capacity at the head. Test results suggest that noncontact lap splices should be modeled using a truss mechanism with diagonal compression struts between opposing bars. Under such a model, the capacity of the lap is determined by an anchorage length defined by the intersection points of the diagonal struts. Using this model, the anchorage behavior of headed bars is similar to previously reported results from CCT node tests in which anchorage consisted of bond and head bearing components. Results show that headed reinforcement can markedly reduce required lap length of spliced reinforcement.


The Kidney Donor Profle Index (KDPI) is a numerical measure that combines ten donor factors, including clinical parameters and demographics, to summarize into a single number the quality of deceased donor kidneys relative to other recovered kidneys. The KDPI is derived by frst calculating the Kidney Donor Risk Index (KDRI) for a deceased donor. Kidneys from a donor with a KDPI of 90%, for example, have a KDRI (which indicates relative risk of graft failure) greater than 90% of recovered kidneys. The KDPI is simply a mapping of the KDRI from a relative risk scale to a cumulative percentage scale. The reference population used for this mapping is all deceased donors in the United States with a kidney recovered for the purpose of transplantation in the prior calendar year. Lower KDPI values are associated with increased donor quality and expected longevity. are associated


Parallel I/O is an essential part of scientific applications running on high performance computing systems. Typically, parallel I/O stacks offer many parameters that need to be tuned to achieve the best possible I/O performance. Unfortunately, there is no default best configuration of parameters; in practice, these differ not only between systems but often also from one application use-case to the other. However, scientific users often do not have the time nor the experience to explore the parameter space sensibly and choose the proper configuration for each application use-case. This paper proposes an auto-tuning approach based on I/O monitoring and predictive modeling, which can find a good set of I/O parameter values on a given system and application use-case. We demonstrate the feasibility to auto-tune parameters related to the Lustre file system and the MPI-IO ROMIO library transparently to the user. In particular, the model predicts for a given I/O pattern the best configuration from a history of I/O usages. We have validated the model with two I/O benchmarks, namely IOR and MPI-Tile-IO, and a real Molecular Dynamics code, namely ls1 Mardyn. We achieve an increase of I/O bandwidth by a factor of up to 18 over the default parameters for collective I/O in the IOR and a factor of up to 5 for the non-contiguous I/O in the MPI-Tile-IO. Finally, we obtain an improvement of check-point writing time over the default parameters of up to 32 in ls1 Mardyn.


ABSTRACT
 Mechanical anisotropy greatly influences the applications of materials printed by additive manufacturing techniques such as Multi Jet Fusion (MJF) and selective laser sintering. However, the mechanical anisotropy of MJF-printed fibre–reinforced polymer composites has not been well understood. In this work, the effect of the fibre length on the mechanical performance of MJF-printed glass fibre–reinforced polyamide 12 (GF/PA12) composites is systematically investigated. Both experimental and simulation results confirm that longer fibres are in favour of fibre alignment in the powder spreading direction. The composite parts with longer fibres exhibit higher porosity. When GFs with an average length of 226 μm are added, the ultimate tensile strength and tensile modulus of the composites measured in the powder bed spreading direction are remarkably improved by 51% and 326%, respectively, as compared with those of neat PA12 specimens. This work provides guidance for the printing of other high-strength fibre–reinforced polymer composites.

340 cases-anesthesia-analgesia.org May 1, 2019 • Volume 12 • Number 9 Copyright © 2019 International Anesthesia Research Society DOI: 10.1213/XAA.0000000000000971 A 36-year-old woman with a history of pulmonary arteriovenous malformations and transient ischemic attacks underwent device closure for a large patent foramen ovale with a 35-mm Amplatzer cribriform occluder (Abbott, Abbott Park, IL) at an outside institution; type of imaging used to facilitate device placement is unknown. Two years later, she presented to our institution because of repeat transient ischemic attacks; a bubble study done at this time demonstrated a grade 2 residual shunt through the discs of the device. Due to the risk of recurrent stroke, she underwent device closure of the residual intradevice shunt with transesophageal echocardiographic (TEE) guidance. Preprocedure midesophageal bicaval view with color Doppler demonstrated a large cribriform device with a right-to-left shunt within the discs of the device exiting into the left atrium (Supplemental Digital Content, Video 1A, http://links.lww.com/AACR/A249; Figure 1A). A bubble study without Valsalva release in the modified midesophageal right ventricular inflow-outflow view revealed a significant residual gap between the occluder discs (Supplemental Digital Content, Video 1B, http://links.lww.com/AACR/ A249) which measured 8 mm in width and 20 mm in length in the midesophageal bicaval view (Figure 2). Initially, a 10-mm Amplatzer muscular ventricular septal defect occluder (Abbott, Abbott Park, IL) was deployed within the discs of the cribriform device. TEE demonstrated a residual shunt, so the occluder was removed. Ultimately, a 14-mm ventricular septal defect occluder was deployed within the discs of the cribriform device. The left disc was completely deployed, while the right disc was lodged within the cribriform discs, with complete obliteration of the shunt. Postprocedure 2-dimensional midesophageal bicaval views with color Doppler (Supplemental Digital Content, Video 2A, http://links.lww.com/AACR/A250; Figure 1B) as well as 3-dimensional en face view from the left atrium perspective (Supplemental Digital Content, Video 2B, http://links.lww.com/AACR/A250) demonstrated a wellseated ventricular septal defect occluder with the left disc in the left atrium held by the cribriform plate while the waist and the right atrial disc remained in the tunnel of the cribriform device. During the postprocedure bubble study, there was an appearance of bubbles in the left atrium after 3–4 cardiac cycles in the midesophageal 4-chamber view. However, the bubbles did not cross the device but instead arose from the left upper pulmonary vein in a "ramp-up" pattern which was suggestive of a pulmonary arteriovenous malformations (Supplemental Digital Content, Video 2C, http://links.lww.com/AACR/A250) that was later confirmed by computed tomographic angiography.

Objective To study mutagenic effect and cytotoxicity of typical environmental water in a city.Methods Reverse phase C-18 solid-phase extraction(RP-C18SPE) was used for the extraction of compounds from the water samples collected from reclaimed water,water source,river water and scenic water.MTT and Ames test were used to detect cytotoxicity and genetoxicity respectively.Results MTT test showed that all the four kinds of water could induce decrease of viability of CHL cells.Reclaimed water and river water could induce mutation of TA98 and TA100 strains with or without S9 at the dose of 500 ml/dish or 1 000 ml/dish.Scenic water could induce mutation of TA98 and TA100 strains only with S9 at the dose of 1 000 ml/dish.Negative results were found in source water.Conclusion In a city,the organic extract of environmental water is cytotoxic at a certain exposure level.The organic extract of reclaimed water and river water is mutagenic before and after metabolic activation and that of scenic water may lose mutagenicity after metabolic activation.


In the 1950s, Landau, Pomeranchuk, and Migdal (LPM) predicted that the cross section for bremsstrahlung from highly relativistic particles in dense media would be suppressed due to interference between amplitudes of nearby interactions. We have measured the production rates of 5 to 500 MeV photons from 8 and 25 GeV electrons traversing thin gold and carbon targets. We observe, to within 5% accuracy, suppression at the level predicted by Migdal. For extremely thin targets, we observe ``edge effects`` where the LPM suppression is reduced near the edges of the targets. We also point out the imprecise foundation of the LPM theory.


Claims that emotions are or can be rational, and crucially ena- bling of rationality, are now fairly common, also outside of philosophy, but with considerable diversity both in their assumptions about emo- tions and their conceptions of rationality. Three main trends are worth picking out, both in themselves and for the potential tensions between them: accounts that defend a case for the rationality of emotions A) by assimilating emotions closely to beliefs or judgements; B) in terms of the very features that traditional views of emotions as irrational/a-rational emphasized; C) by arguing that emotions exhibit a more sui generis kind of rationality, often one based on a narrative or dramaturgic "inner logic".


Abstract Background Aortic aneurysm occurs in the thoracic and abdominal sections of the aorta and is a deadly late-age-at-onset disease. Thoracic aortic aneurysms (TTAs) are characterized by progressive smooth muscle cell rarefaction due to impaired extracellular matrix. The aim of this study was to investigate fibrillin-1 (FBN-1), fibronectin-1 (FN-1) and tissue inhibitors of metalloproteinases-3 (TIMP-3) gene expression levels in patients with TTA. Materials and methods The data were analyzed for 16 patients treated for TAA and nine control subjects. Tissue samples obtained during surgery were frozen immediately in liquid nitrogen and stored at −80°C until RNA isolation. Gene expression analysis was performed by quantitative reverse transcription polymerase chain reaction for each gene and Beta actin was used as control gene. 2−ΔΔCT method was used for the determining expression levels of the genes. Results According to the results of this study, TIMP-3 gene was nine-fold higher expressed in TAA tissues (p = 0.034). Furthermore, TIMP-3 expression levels were found associated with fasting blood glucose, red blood cells and ejection fraction. The gene expression levels of FBN-1 and FN-1 were not statistically significant (p > 0.05). Conclusion In this clinical trial, we concluded that TIMP-3 expression increases in dilated aorta.


Introduction The unique recombinant forms (URFs) of HIV-1 consist of a mixture of subtypes, and each URF has a unique breakpoint. In this study, we identified the near fulllength genome (NFLG) sequences of two novel HIV-1 URFs (Sample ID: BDD034A and BDL060) isolated during HIV-1 molecular surveillance in 2022 in Baoding city, Hebei Province, China. Methods The two sequences were aligned with subtype reference sequences and CRFs from China using MAFFT v7.0, and the alignments were adjusted manually using BioEdit (v126.96.36.199). Phylogenetic and subregion trees were constructed using MEGA11 with the neighbor-joining (N-J) method. Recombination breakpoints were identified by SimPlot (v3.5.1) based on Bootscan analyses. Results Recombinant breakpoint analysis revealed that the NFLGs of BDD034A and BDL060 were composed of CRF01_AE and CRF07_BC, containing seven segments, respectively. For BDD034A, three CRF01_AE fragments were inserted into the CRF07_BC main framework, whereas for BDL060, three CRF07_BC fragments were inserted into the CRF01_AE main framework. Discussion The emergence of the CRF01_AE/CRF07_BC recombinant strains indicates that HIV-1 co-infection is common. The increasing genetic complexity of the HIV-1 epidemic in China warrants continued investigation.

This brief describes a type-I analog sampling phase-locked loop (S-PLL) featuring reference-feedthrough-suppression and narrow-pulse-shielding techniques in a single path to improve the reference (REF) spur. Specifically, we realize the former by inserting a T-shape switch with one center-tap ground, while the latter tackles the voltage ripple caused by the sampling non-idealities. Also, we can tune an external varactor to eliminate both the gain variation of the phase detector and the gate leakage of the frequency-tuning varactor. Prototyped in a 28-nm CMOS, the proposed S-PLL achieves a −78.6-dBc REF spur and 124.6-fs integrated RMS jitter. The corresponding jitter-power Figure-of- Merit is −252.8 dB.


B. Alex Brown iVational Superconducting Cyclotron Laboratory and Department of Physics and AstronomyM, ichigan State University, East Lansing, Michigan 48824-1321 (Received 18 February 1992) Calculations are presented for the Gamow-Teller strength distribution in the P+ decay of "Ca and compared to results extracted from recent beta decay data and from (p,n) data on the analog nucleus Cl. The strength distribution is shown to be sensitive to the Hamiltonian, and comparison with experiment indicates a need for further improvement in the ls0d shell Hamiltonian. It also indicates that the quenching of the Gamow-Teller operator in the upper part of the lsOd shell is similar to that deduced from previous analyses.


Title: "Association between the Strength of Local Geomagnetic Field and Cases of Acute Myocardial Infarction with ST-segment Elevation Clinical and Demographic Data". The aim: to assess the relationship between the different local geomagnetic field strengths and clinical and demographic data of patients with ST-elevation myocardial infarction (STEMI). Objectives: 1) To estimate the relationship between the strength of the geomagnetic field and the number and age of the patients with STEMI; 2) To estimate the relationship between the strength of the geomagnetic field and the number of deaths from STEMI; 3) To estimate the relationship between geomagnetic field strength and STEMI patients with arterial hypertension (AH) and diabetes mellitus (DM); 4) To estimate the relationship between the geomagnetic field strength and the incidence of atrial fibrillation (AF) in patients with STEMI. Methods: a total of patients were included and patients history was analyzed. Patients were divided into groups according to gender, mortality, morbidity of AH, DM and AF. The association of this data with the strength of the local geomagnetic field was correlation analysis displayed association between number of all STEMI patients in a month with the local geomagnetic field strength at different frequency ranges. A moderate negative correlation in SDelta 3.5] Hz and in the [0; 65] Hz intervals was found and a strong negative correlation was found in following intervals: STeta 7], SAlfa 15], SBeta 32] (Hz). a significant relationship between the geomagnetic field strength and the incidence of STEMI in hypertensive patients: the moderate negative correlation observed between SDelta and STeta, SAlfa [7; 15] and SBeta [15; 32] (Hz) a strong negative correlation. A significant correlation between the geomagnetic field strength and STEMI patients with AF observed in the population: a moderate negative relationship in SDelta 3,5], [3,5; 7] and SAlfa [7; 15] (Hz) intervals. Conclusions: a weaker local geomagnetic field was associated with a higher incidence of STEMI, a higher incidence of AH in cases of STEMI and a higher incidence of AF in women with STEMI. Abstract : The impact of changes in the geomagnetic field on the human body remains the subject of studies across the world, yet there is no consensus. Current studies are observing effects that require further work by researchers in order to find out the mechanisms that would allow a proper assessment of the correlations between the Earth's magnetic field variations and changes in human organisms. The main purpose of this study was to investigate possible correlations between the strength of time-varying aspects of the local Earth's magnetic field and incidence of myocardial infarctions. Study participants included 435 males and 268 females who had diagnosis of myocardial infarction during the period of 1 January 2016 to 31 December 2016 and attended the Department of Cardiology at the Hospital of Lithuanian University of Health Sciences (LUHS), Kauno klinikos. Time varying magnetic field data was collected at the magnetometer site located in Lithuania. After mathematical analysis, the results support the hypothesis that the Earth's magnetic field has a relationship between the number of acute myocardial infarction with ST segment elevation (STEMI) cases per week and the average weekly geomagnetic field strength in different frequency ranges. Correlations varied in different age groups as well as in males and females, which may indicate diverse


Mr. Frank Buckles died on February 27, 2011, of natural causes. It was a Sunday in Charles Town, West Virginia and he was 110 years old. He was also the last surviving American veteran of World War I—the last doughboy. As happened so often, he had to lie about his age (16) in order to enlist. Although he spent most of the war as a courier in England, he eventually finagled his way to France. Unhappily, his assignment was not to kill Huns; rather, he was ordered to escort a dentist to Bordeaux. The closest he would ever get to the proverbial whites of their eyes was only after the armistice; his unit was assigned to accompany POWs back to Germany ("The Last Doughboy . . . ," 2011). With his passing we interred at Arlington the last set of American eyes to have looked directly upon what turned out to be neither the war to end war nor the great war considering its ugly brutality. Buckles was eager to insert himself because he considered the war "an important event. . . . The world was interested in it. I was interested." Yet the passage of time, of course, turns bearing witness into burying witness: inexorably, secondary


The hydrosphere which is still the unexplored frontier of our planet is receiving the special attention of scientists and engineers because of its vast potential. A comprehensive knowledge of the properties of marine sediments is essential for most engineering activities in the oceans. A free fall penetrometer designed and developed at Memorial University is a potential tool for a quick and economic evaluation of the geotechnical properties of the top few metres of surficial ocean sediments. -- In addition to measuring the cone resistance and sleeve friction, the deceleration is measured by an accelerometer mounted within the penetrometer. These quantities are then used for correlating the shear strength of the soil at different depths of penetration. Laboratory experiments were conducted with two types of soil targets. -- Test results show that an increase in soil strength and roughness of the penetrometer cone material would cause a substantial increase in cone resistance and decrease in maximum penetration depth. Cone angles and weight per unit area of the penetrometer have also significant influence on the cone resistance and penetration depth. The effect of all these parameters on penetration behavior are discussed. -- The mode of soil failure at low velocity penetration was assumed to be similar to a conventional quasi-static case as proposed by Meyerhof (1961). It was observed that results of free fall penetration tests showed a greater penetration resistance, compared to the standard quasi-static tests. However, when the results were translated into computation of the angle of shear resistance, the difference was insignificant. For cohesive soils penetration resistance is dependent on the penetration velocity. 'Strain-rate effect' was found to influence the results. 'Static' strength for clays from 'dynamic' strength profiles can, however, be obtained taking the 'strain-rate effect' into account.


In the current climate, the veil is the key visual symbol of Islam. The veiled female body is central in the construction of discourses on the difference of the Muslim as 'other' with the non-Muslim 'self'. The effect is that the multiple meanings of the veil are erased, and only one stands out: the veil as a symbol of gender inequality. This article explores the ways in which the visibility of the veil in the public gaze marks its wearers as particularly vulnerable to expressions of Islamophobia in a non-Muslim country such as the United Kingdom. Whilst the concept of Islamophobia is often understood in gender-neutral ways, evidence suggests that there are gendered dimensions to manifestations of Islamophobia in the public sphere. Stereotypes about veiled women's subservience coupled with the assumption that their Muslim identity cannot be mistaken, denied or concealed, renders veiled women 'ideal subjects' against whom to enact anti-Muslim hostility. For victims, their families and the wider Muslim community, Islamophobic victimization can have significant and ongoing consequences. The article concludes that increased awareness of the gendered facets of Islamophobia unveils the targeted – yet hidden, often invisible – victimization of veiled Muslim women in public, as this victimization tends to fall under the criminal justice 'radar'.


Lesions caused by bluetongue virus infection of the central nervous systems of sheep and mice vary with age of the host. The character of the lesions appears to be influenced by the stage of immunological maturity of the infected animals.

If the weak bosons W* and 2 were manifestations of a composite structure of the weak interactions rather than the commonly assumed gauge bosons of a fundamental gauge symmetry one is naturally led to expect a corresponding spectrum of other new weak vector bosom such as weak isoscalars. Experiments at the LHC are of great value in establishing the true nature of the weak interactions.


Sustainability and sustainable development, defined by their economic, social and environmental dimensions, are clearly one of the major challenges for society. The ongoing debate on the link between sustainability and business is whether sustainability management creates value. In a turbulent business environment characterized by rapid change and uncertainty, there is a growing business need for support in understanding the complexity of sustainability issues and their economic implications, and for decisions which address
problems, such as carbon emission reduction, increasing energy costs and material consumption, and resource scarcity.
Accounting for the environmental, economic and social (or sustainability) impacts of organisational strategies and actions has been a growing area of practice and research in recent years. Sustainability requires a balanced approach to environmental, economic and social performance. Business practices in this area encompass provision of information within organisations to help managers at different levels appreciate the potential corporate sustainability impacts on and of their decisions. Environmental and Sustainability Management Accounting (EMA) provides decision-makers with tools and approaches towards improving the sustainability performance of companies and organisations, thereby contributing to more sustainable corporate bottom lines and sustainable value


Vehicle reidentification(ReID) has attracted much attention and is significant for traffic security surveillance. Due to the variety of views of the same vehicle captured by different camera and the great similarity in the visual appearance of different vehicles, it is necessary to explore how to effectively utilize local detail information to achieve collaborative perception to highlight discriminative appearance features. Different from existing local feature exploration methods that focus on using extra part or keypoint information, we propose a global collaborative learning Transformer guided by local abstract features, named LG-CoT, which aims to highlight the highest-attention regions of vehicle images. We adopt Vision Transformer(ViT) as our backbone to extract global features and obtain all local tokens. To reduce the distribution from the background and drive the network to focus more on details, all attention maps containing low-level texture information and high-level semantic information are multiplied to obtain the local regions with highest-attention. Finally, we design a local-attention-guided pose-optimization feature encoding module, which can help the global features focus on local regions adaptively. Extensive experiments on two popular datasets and a dataset we built in a T-junction traffic scene suggest that our method can achieve comparable performance.


The article is devoted to the problem of the study of street advertisements as a special vocal genre. The characteristic signs of street declarations as a vocal genre are revealed: communicative purpose, the image of the author and the presence of addressee, the images of the past and of the future, the type of event-related content, and the parameter of lingual embodiment. Also such important aspect of street advertisements as cliche is genre forming.


reactions for the body; therefore, pain is necessary for life to protect the body. However, chronic pain is only an aversive feeling that produces various physical symptoms, such as decreased appetite, lower satisfaction with life, anxiety, mood disturbance, depression and poor sleep. These symptoms reduce the quality of life of patients. Of these symptoms induced by chronic pain, sleep disturbance is well known to influence the social life of patients. Patients with chronic pain, together with postherpetic neuralgia, diabetic peripheral neuropathy and complex regional pain syndromes, often experienced sleep disturbances, such as delayed sleep onset, and difficulty in maintaining sleep and remaining asleep; therefore, an animal model of these conditions is needed to develop useful medicine for insomnia. There have been a few papers about sleep patterns in chronic constriction injury (CCI) rats reported as a neuropathic pain model, however, conflicting findings are demonstrated, that is, one paper showed no significant alterations of sleep parameters, whereas another reported the opposite results. It seems difficult to assess the effects of hypnotics for sleep disturbance using only CCI model rats. Therefore, in the present study, we investigated the changes of sleep patterns in rats with CCI under aversive conditions.


Stylistics is one of the most important issues in literary text. Its goal is to decode literary meanings and structural features of literary texts by identifying linguistic patterns and their functions in the texts. The aim of this study is to survey the theory of stylistics and its practical application at Forough Farrokhzad's poems. The presented study investigates stylistic devices at works which have been published in five volumes, entitled "The Captive" [Asir], "The Wall" [Divar], "Rebellion" [Esian], "Another Birth" [Tavallodi Digar], "Let Us Believe in the Beginning of the Cold Season" [Iman biyavarim be Aghaz-e Fasl-e Sard]. Literary work can evaluate contract stylistics from various dimensions as this paper examines several stylistic devices and linguistic variations such as "rhyme", "alliteration", "repetition", "assonance", and "onomatopoeia" at Farrokhzad's poems. Stylistics and linguistic variation at Forough Farrokhzad's poems are the fundamental issues at this article. These concepts like other feelings and affections of mankind are the main theme sections of the contemporary literature. In the next section, this paper investigates several themes found among Farrokhzad's poems. In general, the main goal of the article is that the reader by deliberation at poetical samples of Forugh and other lateral discussions – which are presented in various parts of the article- be able to figure out the approach and attention of Forugh on the used concepts in her verses about separation, lack of happiness, sin, disobedience, deliverance of self, etc.


An improvement is made on our previous band results of Sr2CuO3 and Sr2CuO2Cl2 by including the extended Sr 4p valence orbital in the present self-consistent calculations. The differences between our improved results and those of others are mainly due to different evaluation of the ionicity in these compounds.

Sustainable development aims at transforming existing way of development, which is gradually moving towards our planet's ecosystem destruction and hypertrophied economic growth at the cost of other social life areas. In this paper, we prove that sustainable development of society implies changing methods of development themselves. The aim of this paper is to study possibilities and prospects for implementing principles of sustainable development in education sector, which essence is understood as developing ways of development and thinking themselves. To achieve this goal, dialectics is used as general theory of development, specifically its distinctive ability to differentiate qualitative, essential development from quantitative growth, quantitative transition within one essence. This paper proves that sustainable development is impossible without radical transformation of ways of activity, production, thinking and world perception. In this context, alternative potential, represented by "information society" models, is analyzed. Considering that desired model of sustainable development of society should not be only abstract ideal, it is proved that it might and should be embodied in daily practical activities today. Education as an area for intersubjective interaction where development of human subjectivity takes place has always been not only sector fulfilling existing society demands but also anticipating future society opportunities.


Thousands of (Quantitative) Structure‐Activity Relationships (Q)SAR models have been described in peer‐reviewed publications; however, this way of sharing seldom makes models available for the use by the research community outside of the developer's laboratory. Conversely, on‐line models allow broad dissemination and application representing the most effective way of sharing the scientific knowledge. Approaches for sharing and providing on‐line access to models range from web services created by individual users and laboratories to integrated modeling environments and model repositories. This emerging transition from the descriptive and informative, but "static", and for the most part, non‐executable print format to interactive, transparent and functional delivery of "living" models is expected to have a transformative effect on modern experimental research in areas of scientific and regulatory use of (Q)SAR models.


Artificial (CoO-)Co/Nb/Co trilayers (TLs) are studied by means of magnetization, transport, and magnetic force microscopy measurements. By using these TLs as a model system, we provide definite means to distinguish the exchange-fields and stray-fields based magnetoresistance effects observed in relevant Ferromagnetic/Superconducting/Ferromagnetic (FM/SC/FM) structures. Accordingly, we isolate and exclusively focus on the stray-fields version, to report a complete supercurrent switch, ΔR/Rnor ≈ 100%, achieved at operating temperature T > 4.2 K. Detailed series of Co(60 nm)/Nb(dNb)/Co(60 nm) TLs are studied, in which all crucial parameters that relate to the outer Co layers and to the Nb interlayer were systematically varied to unveil the factors that motivate and/or promote the observed effect. We propose a compact model that fairly captures the underlying physics of the Co(60 nm)/Nb(dNb)/Co(60 nm) TLs studied here and can be generalized to assist understanding of the relevant processes in every kind of FM...


The juvenile period represents a serious impediment in olive breeding programs. Seedlings with long juvenile period are of very low interest for the breeder because their evaluation considerably delays the first stages of the breeding process. For this reason, the influence of seedling vigour (measured as plant height or stem diameter) on the characteristics at the adult stage was studied to establish useful negative preselection criteria on the basis of that relationship. Olive progenies from crosses and open pollinations of 12 different parents carried out in 1998 and 1999 were evaluated in the greenhouse and, afterwards, during the first 3 years of bearing in the open field. The results obtained indicate that early evaluation and selection for juvenile period can be performed at the seedling stage in olive progenies on the basis of vigour measurements. Selection for short juvenile period was valid irrespective of parentage and, therefore, could be efficient in a general context. No relationship between juvenile period and yield or fruit traits was found so that this preselection criterion would have no adverse effects on these characters.


New bis(oxamato)palladate(II) complexes, [Pd(H2O)4][Pd(2,6-Me2pma)2]·2H2O (1), (n-Bu4N)2[Pd(2,6-Me2pma)2]·2H2O (2a), and (n-Bu4N)2[Pd(2,6-Me2pma)2]·2CHCl3 (2b) (2,6-Me2pma = N-2,6-dimethylphenyoxamate and n-Bu4N+ = tetra-n-butylammonium), have been synthesized and the structures of 1 and 2b characterized by single-crystal X-ray diffraction. Complex 1 is a double salt constituted by tetraaquapalladium(II) cations and bis(oxamato)palladate(II) anions interlinked by hydrogen bonds. The palladium(II) ions in 1 are four-coordinate with two oxygens and two nitrogens from two fully deprotonated oxamate ligands (anion), and four water molecules (cation) building centrosymmetric square-planar surroundings. Centrosymmetric bis(oxamato)palladate(II) anions occur in 2b as in 1, the charge balance in this compound being ensured by the bulky n-Bu4N+. The catalytic role of 1 and 2a for the Suzuki reaction has been investigated by using a series of aryl iodide/bromide derivatives in the conventional organic medium dimethylformamide. The tetraaquapalladium(II) unit in 1 appears to be active in the catalytic Suzuki cross-coupling reactions, but it readily decomposes to inactive palladium black. Graphical Abstract


The advent of the full-fledged Internet of Things era will bring together various types of information through Internet of Things devices, and the vast amount of information collected will be generated as new information by the analysis process. To effectively store this generated information, a flexible and scalable cloud computing system is advantageous. Therefore, the main determinants for effective client system acceptance are viewed as motivator factor (economics, efficiency, etc.) and hindrance factor (transitional costs, security issues, etc.) and the purpose of this study is to determine which detailed factors play a major role in making new system acceptance decisions around harm. The factors required to determine the major priorities are defined as the system acceptance determinants from the technical point of view obtained through the literature review, and the questionnaire is prepared based on the factors derived, and the survey is conducted on the experts concerned. In addition, the AHP analysis aims to achieve a final priority by performing a bifurcation between components for measuring a decision unit. Furthermore, the results of this study will serve as an important basis for making decisions based on acceptance (enabling) of technology.


In view of problems of the fault leakage judgment, misjudgment and some faults which can not be judged in transformer fault diagnosis, this paper presents a transformer fault diagnosis model based on fuzzy Petri nets. The transformer fault diagnosis model is used to judge the type of the transformer faults through the analysis of the oil dissolved gas concentration. The method firstly uses gas chromatography to get the concentration value of each gas, and then calculates the rate of the gas growth to judge whether the faults happen. If the fault happens, the probability of each type of failure is calculated based on the model of the Petri nets. The method can avoid the lack of coding of three ratios, so that it can solve effectively the problems of the transformer fault diagnosis, misdiagnosis and missed judgment, as well as can provide the probability of each failure in a quantitative way, thus it improves the diagnostic accuracy.


Moisture-dependent engineering properties of seeds are important in the design of postharvest equipment for their handling and processing. In this study, the physical properties of shea kernels were determined as a function of moisture content in the range of 6.24 to 25% (d.b.) using standard techniques. The results showed that with increasing moisture content, the major, intermediate, minor, arithmetic mean diameter, geometric mean diameter, sphericity, aspect ratio, true density and porosity all increased non-linearly from 18.33±0.81 to 31.20±1.21, 10.77±1.07 to 22.50±0.87 and 9.33±0.81 to 16.17±1.07mm, 12.81±0.73 to 23.29±1.00mm 12.22±0.81 to 22.40±1.02mm, 66.68±4.10 to 71.79±1.51%, 58.73±5.24 to 70.07±1.51%, 1.04±0.10 to 1.54g/cm 3 and 44.67 to 72.37% respectively as moisture content increased from 6.24 to 25%. Surface area, 1000-kernel mass, volume and filling angle of repose all increased linearly from 470.47±61.64 to 1578.53±145.83mm 2 , 3.63±0.15 to 11.20±0.60kg, 1.46±0.28 to 8.95±0.13cm 3 and 35.47 to 40.89 0 respectively at the same moisture range. Also, static co-efficient of friction on plywood, galvanise steel, stainless steel and glass increased linearly from 0.43±0.01 to 1.78±0.02, 0.37±0.01 to 1.39±0.03, 0.28±0.03 to 1.12±0.01 and 0.21±0.01 to 0.93±0.01 respectively. Finally, bulk density decreased non-linearly from 0.78±0.01 to 0.35±0.06g/cm 3 . Data was analysed using SPSS (Version 16) and Microsoft Excel (2010). Analysis of Variance (ANOVA) was carried out to assess the variation of each parameter within the moisture range. Differences in the means were compared using Duncan Multiple Range Test (P=0.05). Regression analyses were conducted to establish the relationship between the physical properties of shea kernel and moisture content. Differences in the means of most parameters determined were statistically significant within the moisture range investigated.

Color correction between two or multiple images is very crucial for the development of subsequent algorithms and stereoscopic 3D camera system. Even though various color correction methods are proposed recently, there are few methods for measuring the performance of these methods. In addition, when two images have view variation by camera positions, previous methods for the performance measurement may not be appropriate. In this paper, we propose a method of measuring color difference between corresponding images for color correction. This method finds matching points that have the same colors between two scenes to consider the view variation by correspondence searches. Then, we calculate statistics from neighbor regions of these matching points to measure color difference. From this approach, we can consider misalignment of corresponding points contrary to conventional geometric transformation by a single homography. To handle the case that matching points cannot cover the whole regions, we calculate statistics of color difference from the whole image regions. Finally, the color difference is computed by the weighted summation between correspondence based and the whole region based approaches. This weight is determined by calculating the ratio of occupying regions by correspondence based color comparison.


From a purely none-general relativistic standpoint, we sol ve the empty space Poisson equation (∇Φ = 0) for an azimuthally symmetric setting, i.e., for a spinning gravitational system like the Sun. We seek the general solution of the form Φ = Φ(r, θ). This general solution is constrained such that in the zeroth order approximation it redu c s to Newton's well known inverse square law of gravitation. For this general solution, it is s een that it has implications on the orbits of test bodies in the gravitational field of this spinn ing body. We show that to second order approximation, this azimuthally symmetric gravitat ional field is capable of explaining at least two things (1) the observed perihelion shift of solar p l nets (2) that themean Earth-Sun distancemust be increasing – this resonates with the observations of two independent groups of astronomers (Krasinsky & Brumberg 2004; Standish 2005) who have measured that the mean Earth-Sun distancemust be increasing at a rate of about 7.0 ± 0.2 m/cy (Standish 2005) to 15.0± 0.3 m/cy (Krasinsky & Brumberg 2004). In-principle, we are able to ex plain this result as a consequence of loss of orbital angular momentum – this lo ss of orbital angular momentum is a direct prediction of the theory. Further, we show that th e theory is able to explain at a satisfactory level the observed secular increase Earth Year ( 1.70 ± 0.05 ms/yr; Miura et al.2009). Furthermore, we show that the theory makes a significant and t estable prediction to the effect that the period of the solar spin must be decreasing at a rate o f least8.00 ± 2.00 s/cy.


The operative procedure for lower third esophageal cancer proposed by the authors ensures more radical surgical treatment as evidenced by frequency of regional lymph node metastasis detection (61.1% in the test group versus 16.1% in the control, p<0.02). Besides, the procedure prevents disease recurrence in the esophagogastric anastomosis area (0% in the test group versus 12.9% in the control). Favorable conditions for esophagogastric anastomosis at the level of the vena azygos provide a 18.3-fold reduction in the risk of anastomosis failure, a severe early postoperative complication (2.8% in the test group versus 51.6% in the control, p<0.02). The proposed thoracotomy approach allows up-to-date surgical treatment including twofield lymph node dissection.

notion of mental illness as a condition simultaneously involving the mind, the body and the environment. Throughout the book, Baum examines how various actors – the state bureaucracy, the Western-trained psychiatrists, the "psychiatric entrepreneurs," the families of the mentally troubled individuals, and so on – applied various worldviews and strategies to achieve a diverse array of needs. At various historical locales, madness became stigmatized, naturalized, commodified and regulated under the influences of intersecting medical, political, moral and commercial forces. Gradually, madness reached a broader scope, acquired new meanings and entered the purview of the state and the psychiatric profession. Baum locates her studies primarily in Beijing but nimbly expands to the whole country as well as intellectual exchanges on the international stage. This methodological decision is well coordinated with her objective: using psychiatric modernity as a lens to illuminate China's modernization as a whole. Overall, Baum's book is highly informative, intriguing and elegantly written, deserving attention from all historians and social scientists who study relevant topics.


Production of Luzhou- flavor liquor is based on pits where ample microbial communities are living, and interactions among all sorts of microbes especially Bacilli in it make fermented sapor of Luzhouflavor liquor very unique. In this study, 23 aerobic Bacilli were isolated from 300- year pit mud of cellar affiliate to Luzhou laojiao, Luzhou, Sichuan Province. Microscopic and colonial morphology analysis showed that the difference between these aerobic Bacilli were not significant. Through PCR amplification of 16 S rDNA gene and NCBI blast, a phylogenetic tree was preliminarily constructed. The results showed that the strains of aerobic Bacilli were mainly Bacillus thuringiensis, B. cereus and B. anthracis. The genetic relationship of these strains was inconformity. As a whole, the phylogenetic relationship was close and the genetic polymorphism was low between these Bacilli isolated from 300300-year pit mud. Aged pit mud was always in the surroundings of anaerobic or facultative anaerobic, studying on the survival condition and genetic relationship of the aerobic Bacilli in aged pit mud was helpful to get a insight in the change of surrounding environment during the liquor fermentation, and improve the quality of liquor. The result provides basic data for research on the change of surrounding environment during the liquor fermentation, and improving the quality of liquor.

China transported the lunar rovers to the lunar surface via the Chang'E rockets for lunar exploration. An important detection tool in the lunar rover is the lunar penetrating radar (LPR). LPR can obtain the lunar surface structure information by transmitting and receiving high-frequency electromagnetic waves. There are many types of waves received by LPR sensors, among which diffracted waves are often ignored. The diffractions in the LPR data contain a lot of underground structure information, especially for faults and small targets with high resolution. A major technical problem in effectively using the information is how to separate diffractions from different types of wave field information. This paper focuses on the diffraction issue and employs the plane wave decomposition filter method to separate the diffractions in LPR data sets. First, the records are converted into a dip field, and then the non-diffraction waves in the dip field is filtered to achieve the purpose of separating the diffractions. Three numerical models will be used to verify the effectiveness of the diffraction separation method.


Non-uniform corrosion of steel bars causes concrete cracking in chloride-contaminated reinforced concrete (RC) structures. The degree of surface cracking of the concrete reflects the corrosion intensity of the internal reinforcement. Thus, it is essential to investigate the corrosion and bond performance of RC after cracking. The electrochemical corrosion method was used to assess the influence of steel bar corrosion on the RC specimens. Non-uniform radial displacement of the steel bars was considered, and a non-uniform theoretical model was used to evaluate the cracking behavior of the concrete cover. The corrosion rate of the reinforcement after cracking was quantitatively analyzed. A pull-out test was performed on the RC specimens after expansion cracking, and the relationship between the bond performance and the crack width was analyzed. A method for determining the influence of the crack width on the bond performance was proposed.


Hyperspectral image has been widely used in land-cover classification. Due to huge amount of data and high correlation between bands, band selection technology is main method to reduce computational complexity. According to non-linear relation between band data, Spectral Clustering (SC) is imported to cluster and select band. In this method, neighbor graph and similarity matrix are generated from band image samples, then samples are divided into k clusters by spectral clustering algorithm. At last, k selected representative samples are generated and used in the subsequent classification and recognition task. Experimental results show that new method can reduce computational complexity and improve classification accuracy of land-cover classification.

Sea-blue Histiocyte Syndrome (SBHS) is a rare and poorly understood systemic histiocytosis that is sometimes associated with haematological and lipid storage diseases as well as other miscellaneous conditions, but in most cases its cause is unknown. Patients often have very disparate clinical features but share the same histological findings of sea-blue histiocytosis in the bone marrow, i.e. characteristic lipid-laden macrophages with deepblue or blue-green granules when stained with Romanovsky or May-Grunwald Giemsa stain. We describe a case of an 8 yearold girl admitted to the emergency department with a history of fever, adynamia, subicteric sclerotics, lymphadenopathies, anemia and leukopenia. During the investigation, histological examination of the bone marrow revealed a Sea blue histiocytosis. Patient workup revealed a spherocytosis, but it was inconclusive regarding major causes for these findings such as Niemann-Pick Disease, Gaucher Disease and other haematologic conditions, and was thus considered a Primary Sea-Blue Histiocyte Syndrome. A review of the literature was then carried out to outline current knowledge of this condition and to establish a rationale for the patient workup and management when such findings are encountered.

This letter deals with the problem of tracking multiple targets on the unit circle, a problem that arises whenever the state and the sensor measurements are circular, i.e. angular-only, random variables. To tackle this problem, we propose a novel mixture approximation of the probability hypothesis density filter based on the von Mises distribution, thus constructing a method that globally captures the non-Euclidean nature of the state and the measurement space. We derive a closed-form recursion of the filter and apply principled approximations where necessary. We compared the performance of the proposed filter with the Gaussian mixture probability hypothesis density filter on a synthetic dataset of 100 randomly generated multitarget trajectory examples corrupted with noise and clutter, and on the PETS2009 dataset. We achieved respectively a decrease of 10.5% and 2.8% in the optimal subpattern assignment metric (notably 16.9% and 10.8% in the localization component).

A free rider is someone who gains the benefit of a collective or public good without contributing to the cost of its provision. The term was introduced to social scientists by Mancur Olson's The Logic of Collective Action, which argued that the problem of motivating collective action is equivalent to the problem of motivating private contributions to a public or shared good. Olson's use of the term is structural: a person is a free rider if they benefit from a public good without contributing to it, regardless of their awareness of the possibility of contributing. A more restricted meaning refers to conscious free-riding, in which a person prefers to benefit from the actions of others.

Neuropathic pain, initiated or caused by a primary lesion or disease in the peripheral or central nervous system, is best treated by first defining the aetiology, then treating the primary cause such as diabetes or rheumatoid arthritis, and thirdly, initiating appropriate and adequate doses of pain-relieving medication. 'Frequently, patients are referred to us at the Pain Clinic with appropriate pain-relieving therapy, but at very timid doses', Dr Milton Raff, Christiaan Barnard Memorial Hospital said at the recent FCPSA congress.

This study examines and compares the rhetorical ton e f two deliberations on developing sustainability reporting: development of limited mandatory reporting of legally binding remediation liabilities within the financia l reporting framework, and the development of broad-scope voluntary reporting within the Globa l Reporting Initiative (GRI) reporting framework. While the organizational sponsors of these two init iatives differ, similar interests actively participated in shaping each – corporate a c ors, accountancy organizations, financial sector participants. In addition, members of civil society interested in advancing greater transparency in corporate environmental performance joined the GRI development, suggestive of the broader scope of this reporting i nitiative. This last group of actors includes actual, as opposed to theoretically conceptualized, users of the reports around which the deliberations form. In both contexts participants were engaged in a process of making meaning, and of developing new institutional norms. Convincing argumentation is required to cast a preferred approach in winning terms that will be adopted as a new norm of sustainability reporting. The study utilizes instit utional theory and the perspective of metaconversation developed within that by Robichaud et al. (2004). This perspective is applied beyond the scope of a single organization t o examine ways in which discursive identities are used in efforts to expand and transp l t these identities, and their rules of operation, to newly emerging communities of practic e. The methodology of content analysis focusing on language-as-action is used to examine r heto ical strategies in the comment letters received by the American Institute of Certified Pub lic Accountants (AICPA) and the GRI as part of these two deliberation episodes. The two d eliberations are examined individually and also in comparison to one another in an effort to e xplore the discursive work that is undertaken.


This study takes Shaoguan City, Guangdong Province as an example to study tourists' perception of local tourist food image. The research method uses the Kelly grid technique. Through interviews with 24 tourists who have travelled to Shaoguan, 36 key constructs are obtained, and they are divided into cognitive and emotional constructs. Seven final representative constructs are presented. After sub-analysis, it was found that Shaoguan's tourism food development is lagging behind, the food environment needs to be improved, and the lack of representative food in the city, etc., and proposed to establish representative tourism food, improve dietary hygiene awareness, and use the Internet to increase publicity and other optimization development suggestions.

Mobile Ad-hoc Networks (MANETs) impose strict requirements in terms of battery life, communication overhead and network latency, therefore optimization should be made to applications and services such as domain name service (DNS), dynamic host configuration protocol (DHCP) and session initiation protocol (SIP) if they are to be considered for use on MANETs. Due to the decentralized and self-organizing nature of MANETs, such applications could utilize a distributed name resolution/data storage service. Distributed Hash Tables (DHTs) enable these features by virtually organizing the network topology in a peer-to-peer (P2P) overlay. P2P overlays have been designed to operate on the application layer without knowledge of the underlying network thus causing poor performance. To address this problem, we propose and evaluate two different DHTs integrated with MANET routing in order to optimize the overall performance of MANET communications when P2P applications and services are used. Both architectures share the same functionality such as decentralization, self-reorganization, and self-healing but differ in MANET routing protocol. Performance evaluation using the NS2 simulator shows that these architectures are suited to different scenarios namely increasing network size and peer velocity. Comparisons with other well-known solutions have proven their efficiency with regard to the above requirements.

This paper presents a new technique for estimating the wind friction velocity at the ocean surface from C-band radar scatterometer measurements. This technique uses physical models of ocean surface waves and electromagnetic backscattering from a rough surface at intermediate angles of incidence to generate predictions of the normalized radar cross section (NRCS, or σ 0 ) of the ocean surface for a given wind friction velocity and observational geometry. The ocean spectral model used in this technique has been developed specifically for this application. It combines in situ wave measurements at low wave numbers with the Phillips [1985] equilibrium spectral model. This choice of ocean wave model is supported by a set of open ocean wave measurements summarized in this paper. A suite of models, derived from both in situ and remote measurements of the sea surface, is used to characterize the directional spreading of ocean waves relative to the wind direction. The resulting two-dimensional ocean wave spectra are used with a composite surface model to predict radar backscattering from the ocean surface at C-band. These radar cross-section predictions are combined with ERS-1 scatterometer measurements in a cost function minimization scheme to yield estimates of the friction velocity vector at the ocean surface. We present examples of this technique and compare friction velocity retrievals obtained via this scheme with buoy-based measurements under a variety of wind and wave conditions. On the basis of the analysis of a limited number of cases, this technique yielded friction velocity estimates for which the magnitude was within 22% and the direction was within ±25°. Given that scientific applications require magnitude estimates within 10-15% and directional estimates within ±20° of in situ measurements, these preliminary results suggest that this is a promising approach to wind retrieval.


In this paper , the application of the Equilibrium Point Hypothesis— originally proposed by Feldman for the control of limb movements— to speech control is analysed . In the first part , physiological data published in the literature which argue in favour of such control for the tongue are presented and the possible role of this motor process in a global control model of the tongue is explicated . In the second part , using the example of the acoustic variability associated with vowel reduction , we focus on how the Equilibrium Point Hypothesis could help to search for physical regularities associated with a phonological sequence produced under variable speech conditions : the equilibrium point sequence could be invariant while the level of cocontraction and the timing of the commands could vary with the speech condition .

A combined liquid chromatography coupled to a mass spectrometer with an ICP detector (μSEC-HR ICP MS; μSEC ICP for brevity) technique was used to analyze the metals in four asphaltenes and their corresponding A1 (toluene insoluble), A2 (toluene soluble), and trapped compound (TC, heptane soluble) fractions. For three of the asphaltene samples, the normalized μSEC ICP profiles for both nickel and sulfur were very similar, showing that nickel porphyrins were distributed in almost all types of asphaltene aggregates. Extensive overlapping with sulfur profiles was observed for all vanadium and nickel profiles at retention times below the maximum bands. This suggests that large amounts of nickel and other organometallic or metal-porphyrin-type (MP) compounds are interlocked with asphaltene molecules, forming aggregates in solution. The separation of MP compounds using common separation techniques is very difficult as extraction would require dissociation into several molecules. The presence of TCs (e.g., compou...


The article announces a new concept of media ecology as a scientific field of research within the framework of the paradigm of mediatization of the information space. The term "media ecology" is already used in science, but in a different conceptual meaning. The authors conducted its detuning from existing analogues at the terminological level, specified the field of scientific research of media ecology, designated its thematic field, defined methodological and theoretical bases and research tools. The possibility of using geographical and geoinformation research methods within the framework of the proposed concept is indicated. Examples of maps and geographical studies on media-ecological topics are given. The results of a pilot study on the analysis of empirical material by methods and tools of media ecology on the example of the largest newspaper publications of the three countries are also presented. These are "Rossiyskaya Gazeta" (edition of the Government of the Russian Federation), "Zhenmin Zhibao" (Publication of the Central Committee of the Communist Party of China) and "Asahi Shimbun" (national newspaper of Japan). The study was conducted according to the method of communicative five-stage analysis with elements of comparative geographical analysis. The article contains an examination of the peculiarities of the environmental policy of the three countries, a comparative analysis of the format of publications and a frequency analysis of archives posted on the websites of publications. The authors also compared the traffic to the websites of publications and the average reading time of materials, analyzed the features of feedback and communication with readers. Conclusions are drawn about the degree of effectiveness of the communicative impact of the publications under consideration on the audience. The highest efficiency was found in the Japanese newspaper "Asahi Shimbun", the average—in the "Russian newspaper", and the lowest—in the Chinese "Zhenmin Zhibao".

Strip bending is a simple and productive method for the mechanical characterization of thin-fi lm materials used in micro-electromechanical systems (MEMS) applications. This method can yield a stress-strain curve as does a microtensile test, and can also yield the elastic modulus and strength. The strip bending test is much more useful than the microtensile test because of the ease of specimen fabrication, alignment, and handling. On the other hand, results obtained by the strip bending test can suffer from uncertainties related to specimen shape, and the specimen shape can affect the strain estimation and stress concentration of the specimen. In this study, two types of specimen were fabricated using a MEMS process to investigate the effect of specimen shape. Au was chosen as a thin-fi lm material owing to its widespread use in MEMS applications. The stress-strain curves of Au thin fi lm were measured using a strip bending apparatus equipped with an accurate laser displacement sensor and a load cell of 500 mN capacity. The difference caused by the specimen shape was clearly identifi ed in the stress-strain curves of the two types of specimen of the same Au thin fi lm. A carefully designed microtensile test was performed to accurately measure the stress-strain curve of the Au thin fi lm, and the tensile data was compared with the data obtained by the strip bending method. To understand the mechanics of the strip bending method and the effect of specimen shape, fi nite element analysis (FEA) was performed for 3-dimensional models of the two types of strip bending specimen.
