Abstract It has long been known that a temperature gradient in the snowpack, when temperatures are less than 0°C, can metamorphose the snow to produce a fragile euhedral crystalline end product called "depth hoar" which is considered to be responsible for snowpack collapse and climax avalanches. The wave of metamorphism advancing through anhedral snow converts it, first to subhedral, and finally to euhedral depth hoar. Our field observations, which are at the moment supported by laboratory evidence, reveal that the zone of minimum snow strength in the gradient metamorphic layer is associated with the intermediate subhedral phase rather than with the euhedral end product.


One aspect of image quality that should be considered when migrating scan protocols from single-slice helical CT (SSCT) to multi-slice CT (MSCT) is z-axis high-contrast resolution. The aim of this study was to compare z-axis high-contrast resolution of MSCT with that of a similarly designed SSCT for various combinations of slice thickness and pitch. A point response phantom was used to acquire slice sensitivity profiles (SSPs) and calculate z-axis resolution (10% of MTF). Additionally, a resolution pattern phantom was used to subjectively evaluate limiting z-axis resolution. Both analytical and subjective results revealed that the SSCT had higher z-axis resolution than the MSCT for nominal 5 mm slice thickness (at comparable pitches). However, for nominal 10 mm slice thickness the MSCT demonstrated z-axis resolution that was comparable or superior to SSCT. Additionally, notable differences in the shape of the SSP for axial scans were observed on the MSCT unit due to the presence of detector septa. Several conclusions can be drawn from these results including: (1) z-axis resolution is not necessarily 'better' for MSCT and should be evaluated prior to transferring scan protocols from single- to multi-slice CT, and (2) a simple acrylic plate resolution phantom may be used to quickly and effectively evaluate z-axis resolution.


The eighteenth century, in the middle of which John Flaxman was born, flowed, after it had weathered the Marlborough Wars and the Hanoverian Succession, into the calm seas of the Age of Reason. Before its close it was, however, in England at least, to be almost submerged by the rising tide of Romanticism. Since it is with Flaxman as an eighteenth-century artist that I am now concerned, I must make some attempt to discuss his work against this background; but the field is wide, and I fear I shall inevitably be compelled to over-simplify. Flaxman, who went to the Academy Schools as a boy of fifteen in 1770 and whose earliest remaining sculpture dates from some ten years later, was deeply conscious that about the time he began to work a fundamental change had come over English sculpture. He defines this change as the introduction of a purer style, a rejection of the corrupt and degraded art of the first three quarters of the century. It will no doubt be known to all of you that soon after the middle of the century knowledge of antique works, and especially Greek works, was greatly enlarged. The excavations at Herculaneum and Pompeii brought to light a mass of material, most of it of good quality, for the cities had been buried in A.D. 79, that is before the decline of antique sculpture in the later Roman Empire. This gave a new impetus to excavations in Rome itself; while the journeys of Wood and Dawkins to Baalbec and Palmyra, and of Stuart and Revett to Athens, to name only a few examples, excited collectors and artists alike. It was not until the i760's that the result of these activities became widely available; I shall be referring to some of the chief books later so shall not list them now. Further, in 1765 an important new interpretation of antique art was available to Englishmen in Fuseli's translation of Winckelmann's Reflections on the Painting and Sculpture of the Greeks. This is not of course Winckelmann's most famous book, the Geschichte der Kunst des Alterthums, published in German in 1764, but it contains his most famous passage: "The last and most eminent characteristic of the Greek works is a noble simplicity and calm grandeur in Gesture and Expression. As the bottom of the sea lies calm beneath a foaming surface, a great soul lies calm beneath the passions in Greek figures." It also contains the germ of the idea Winckelmann later expanded in the Geschichte, namely that the history of art was part of the history of civilization, and that rewarding parallels could be drawn between This lecture was delivered at University College, London, on the 5th December, 1955, as part of the celebrations of the bi-centenary of Flaxman's birth. I am grateful to the Provost for permission to publish the lecture, and to Professor William Coldstream and his staff, especially Mr. Andrew Forge, for their help during its preparation. I am also indebted to the Central Research Fund of the University of London for a grant for photography, and to the Photographic staff of the Courtauld Institute for the trouble they have taken on my behalf. Although I should like at some future time to make a more detailed study of Flaxman's activities in Rome, the material is large, and since his Italian sketchbooks are so little known it seemed best to publish the present paper in its original lecture form. 1 See his "Address on the Death of Thomas Banks, I805," printed in J.

Most algebraic calculations involve block matrices and so are highly noncommutative. Here we investigate the usefulness of noncommutative computer algebra in a particular area of control theory - singularly perturbed dynamic systems where working with the noncommutative polynomials involved is especially tedious. Our conclusion is that they have considerable potential for helping practitioners with such computations. The methods introduced here take the most standard textbook singular perturbation calculation one step further than had been done previously. Commutative Groebner basis algorithms are powerful and make up the engines in symbolic algebra packages' Solve commands. We show that the noncommutative Groebner basis algorithms are useful in manipulating the messy sets of noncommutative polynomial equations which arise in singular perturbation calculations. We use the noncommutative algebra package NCAlgebra and the noncommutative Groebner basis package NCGB which runs under it.


The isolation of diphtheroid organisms from rheumatoid synovial membranes and synovial fluids (Duthie, Stewart, Alexander, and Dayhoff, 1967; Clasener and Biersteker, 1969; Stewart, Alexander, and Duthie, 1969) has raised the question of the role of diphtheroid bacilli in the aetiology of rheumatoid arthritis. The view that rheumatoid disease might involve an abnormal cellular immunological response to an infective agent (Walton, 1968) suggested the need to determine whether cellular hypersensitivity to such diphtheroid isolates in subjects with classical rheumatoid arthritis was different from that in non-rheumatoid subjects.


In this paper, we present an ink-reducing printed rectangular CPW antenna structure by defining a proper selective area for thickening the conductive ink layer. In this design, the microstrip feed line and the small section of ground elements near the microstrip feed line are made thicker than the other antenna areas. The simulation results illustrate that the proposed printed antenna structure can significantly reduce the conductive ink consumption by as much as 55% of the conventional flat printed antenna.


The method proposed by the authors in their earlier paper on thermal conductivity has been utilized to estimate the effective elastic constants and the coefficient of thermal expansion of a statistically isotropic heterogeneous medium. The method considers the inclusion geometry in the lower-order correlation functions, that is, those of order two and less. The upper and lower bounds and the improvements on these bounds have been derived for the elastic constants. Expressions containing the two-point correlation functions are also derived for the coefficient of thermal expansion and the related stress tensor. The theoretical values are compared with the experimental results and the comparison can be considered satisfactory in view of the difficulty in obtaining perfectly isotropic distribution experimentally and the sensitivity of the final properties to mild anisotropy when the difference in the constituent properties is large as in the case of Araldite and copper. The theoretical results for the aluminium-copper system show that convergence of the bounds is extremely good when properties of the constituents are of the same order.


The origin of Danchong in Korea can be found in the remains of the Prehistoric Age.In the Three Kingdoms' Age it is observed in the colored pattern on wall and ceiling, and the mural painting with in ancient tombs.Afterward, Goryo Dynasty and ChoSun Dynasty had developed into the new Style of Danchong.


A governmental inquiry into working practices has criticised doctors for "institutional racism." Produced by an all-party Social Security Select Committee, the report contained evidence that people from ethnic minorities are subject to discrimination during medical consultations.

The report examined the work of the Medical Service and its Examining Medical Practitioners, the doctors who examine claimants for the Government Benefits Agency. It follows a recent admission from Mike O'Brien, a Home Office minister, that his department is "institutionally racist". …


Objective To investigate the prevalence,clinical features and the law of development of undifferentiated spondylarthropathies(uSpA).Methods Within five years,127 uSpA patients were registered in rheumatology outpatient clinic of Second Hospital Shanxi Medical University.The clinical,laboratory and follow-up datas of uSpA patients were collected and analyzed.Results(1) The male female ratio is 1.8:1,and the female late onset.(2) The chief symptoms of 127 uSpA patients were lumbar and back pain(93.7%) and joints pain(96.0%).(3) Female patients lower back pain was significantly higher than that of the first male(P 0.05).Some patients with region coxae,hip and heel or other attachment sites pain onset,there first rates of men were higher than female(P 0.05).(4) Seven cases of hand joints involvement as the first symptoms were women.(5) The positive rate of family history and HLA-B27 were 42.5% and 52.8%,there was no significant difference between male and female.(6) The sensitivity of sacroiliac joints CT in the diagnosis of uSpA was higher than X-ray,the two positive rates of Sacroiliitis were 75.0%(78/104),60%(51/85).The emergence rates of sacroiliac joints damage of male was higher than women(P 0.05).(7) In five years 56 cases developed to 18 cases ankylosing spondylitis(AS),1 enteropathic arthropathy,1 psoriatic arthritis(PsA),20 uSpA,16 cases with symptomatic disappear.In 18 cases confirmed AS there were 13 male patients,accounting for 72.2%.In 5 years the positive rates of all sacroiliac joint CT signs had increased,the grade Ⅱ sacroiliac joint destruction progress evidently,the destruction positive rates of the examinations in initial and 5 year later were 3.6% and 48.2%.Conclusions uSpA were a group of a variety of spondyloarthropathy,which had a genetic predisposition.The sacroiliac joint involvement of men was more serious than women.Some patients can progress to ankylosing spondylitis,psoriatic arthritis and enteropathic arthropathy,and other SpA.Close follow-up on the patients and regular line sacroiliac joint CT examination conduce to early diagnosis.


A combination of the boundary element method and the finite element method is used to calculate the stress intensity factors of mixed-mode crack problems. In this method, finite elements are only allocated near a crack tip and boundary elements are used to discretize the rest of the structure. The virtual crack extension method is applied to the finite elements to obtain the stress intensity factor, together with the method for the separation of displacement components into Mode I and Mode II. The analyses are performed for a center slant crack or a center arc crack in a rectangular plate subjected to uniform tensile stress. It is found from the analyses that the present method gives an accurate stress intensity factor for mixed mode crack problems.


The subtitle of this book, which was first published in the United States, is 'A Practical Approach to Ethical Decisions in Clinical Medicine' and the authors are a philosopher, a clinician and a lawyer. The reader is given the benefit of a consensus, as it were, after the authors have discussed each problem amongst themselves. The book is crisp and short but there is an excellent bibliography and as well as a table of contents there is a 'locator' which is very helpful and there is good cross-referencing. These aids are important because instead of the more conventional arrangement of chapters by subject there are only four chapters: Indications for medical intervention; Patient preferences; Quality of life, and External factors. As the authors indicate in the introduction these titles are taken from philosophical literature and based on the 'Principle of beneficence behind indications for medical intervention, the principle of autonomy behind patient preferences and some form of Utilitarianism behind quality of life and external factors'. This grouping


In this paper we study $\prod\limits_{i=1}^{n} \mathbb{Z}_{2^i}$-Additive Cyclic Codes. These codes are identified as $\mathbb{Z}_{2^n}[x]$-submodules of $\prod\limits_{i=1}^{n}\mathbb{Z}_{2^i}[x]/ \langle x^{\alpha_i}-1\rangle$; $\alpha_i$ and $\rm{i}$ being relatively prime for each $i=1,2,\ldots,n.$ We first define a $\prod\limits_{i=1}^{n}\mathbb{Z}_{2^i}$-additive cyclic code of a certain length. We then define the distance between two codewords and the minimum distance of such a code. Moreover we relate these to binary codes using the generalized Gray maps. We define the duals of such codes and show that the dual of a $\prod\limits_{i=1}^{n}\mathbb{Z}_{2^i}$-additive cyclic code is also cyclic. We then give the polynomial definition of a $\prod\limits_{i=1}^{n}\mathbb{Z}_{2^i}$-additive cyclic code of a certain length. We then determine the structure of such codes and derive a minimal spanning set for that. We also determine the total number of codewords in this code. We finally give an illustrative example of a $\prod\limits_{i=1}^{n}\mathbb{Z}_{2^i}$-additive cyclic code.


With the advance of China's energy saving policy,reducing the coal consumption of thermal power generating units has become an important goal of energy conservation.In recent years,1000MW ultra-supercritical unit has developed rapidly for its high efficiency and low energy consumption.Therefore,the energy consumption distribution of a typical ultra-supercritical unit is analyzed in detail to find out its principle,which can make contribution for the energy conservation of units.Based on the theory of unit energy consumption and according to the thermodynamic calculation of a 2×1000MW ultra super critical generating unit under the design condition,this paper shows the distribution of energy consumption of the whole unit,which reflects the ratio of energy consumption of each equipment in the total unit.Based on the results,the energy conservation potential of every equipment can be found out.


The ability of the free vortex trapping is investigated downstream of a backward facing step in potential flow theory.It was found that there exits a stationary position of the free vortex downstream of the step,and the free vortex there is stable.More precisely,it is only neutral stable.To enhance the stability of the free vortex,the effects of the suction applied through the oriffice on side walls were examined.A linearized theory was developed to show that the stationary vortex becomes really stable if the suction is applied.


This chapter tells the story of the events of the 1989 Tiananmen Square massacre inside the foreign ministry and follows the painstaking efforts of Chinese diplomats to salvage China's reputation. In the aftermath of the massacre, the country's diplomats made painstaking efforts to salvage China's international reputation. Channeling the same impulses they'd used to woo the world in the 1950s, the country launched a new charm offensive with its neighbors, embracing tools from economic diplomacy to sports diplomacy, media management, and arms control to try to win friends. At the same time, China's diplomats were branded traitors by nationalists who saw engagement with the United States as a throwback to China's humiliating past after the 1999 bombing of the Chinese embassy in Belgrade.

KORDA'S PRODUCTION OF The Deep Blue Sea has much to recommend it. Vivien Leigh has never been so unhealthily beautiful; Kenneth More, so engagingly yet maddeningly irresponsible; Eric Portman, so charmingly sinister. The entire cast performs admirably. But there is something missing, or, more accurately, there is a good bit that is superfluous. In its translation from stage to screen, Terence Rattigan's serious but limited problem drama has been given the full treatment-Technicolor, background music, a theme song, and authentic scenery. It has been expanded in every possible way, and in every dimension, from the grim little tragedy in the sordid little flat that Peggy Ashcroft occupied in the original London production. In short, the film has opulence, where the play has a pervasive down-at-the-heels colorlessness that verges on squalor. The change has a point, to be sure, but the point may be a different one from Mr. Rattigan's original thesis. We now get flash backs of Sir William Collyer's fashionable residence, which boasts at least one Venetian painting; we see the holiday in the Alps, which presumably was the sort of vacation Lady Collyer was accustomed to taking with her husband. After she leaves him, there are, of course, no such holidays, no art collection, and none of the amenities that Sir William took for granted as one of the normal perquisites of comfortable living. The contrast is so obvious that it is probably not worth making, and in the original script Mr. Rattigan seemed to do his best not to make it. Of course, Sir William's chauffeur does drive him to his wife's unfashionable address, and the limousine is quite naturally left waiting where it will be noticed; but all this is done without ostentation. As Hester grate-


As the technology grows, the security and privacy concerns arise due to the emerging threats of security breaches. CSE is carefully planned to increase the awareness and usage of the privacy/security tools to avoid security breaches. The purpose of the study is to find the relationship between CSE, awareness and usage of privacy/security tools for PCs. Highly developed tools were adopted to measure the variables. The reliability for the measuring tool according to Cronbach's Alpha is 0.955. Data was collected from the business students of the institutions of Lahore. Sample size was 331 out of which 182 were males and 149 were females. Results show that most of the students have CSE level above average and there is no gender effect on CSE, Awareness and Usage of Privacy/Security Tools. Pearson Correlation shows positive and significant relationship between the variables. Results of Multiple Linear Regression show that independent variables, CSE and Awareness of privacy/security tools, are making a significant contribution (56.6%) in predicting the Usage of privacy/security tools. It also shows the overall significance of the model.

Lipschitz continuity of local minimizers of the energy functional of an isotropic compressible hyperelastic material is studied. The functional is a nonconvex function of the deformation gradient. Using a blowup technique it is shown that all local minimizers are Lipschitz continuous everywhere


Recommender systems (RS) are being used by an increasing number of e-commerce sites to help consumers find prod- ucts to purchase. We define here the features that may char- acterize an "intelligent" RS, based on behavioral science, data mining, and computational intelligence concepts. We present our conclusions from building the WiseUncle Inc. RS, named Rubicon, and give its general description. Rather than being an advisor for a particular application, Rubicon is a generic RS, a platform for generating application specific advisors.

Traditionally, the international market selection is a systematic process, based on predefined criteria. This process is, however, very time- and cost-consuming, and only a small number of firms have sufficient resources to do it. So, according to the Uppsala Model, firms tend to internationalize to the closest markets (psychic distance), managing uncertainty in a very gradual process based on experiential knowledge. The second-hand knowledge that flows in the firm's network could help firms select the market, helping them to expand gradually. Independently from the source (experiential or second hand), knowledge seems to be a mandatory resource to internationalize. However, a lot of firms imitate other firms' behavior, selecting the international market according to others' selections, believing that they must have superior information. In this situation, firms could imitate the leader (a successful firm) or the herd (a big number of firms). This international market selection is not based on knowledge; it is a mimetic process.


Present Lake Environment of Hartbeespoort Dam was evaluated from Geochemistry of bottom Sediment. Ten (10) bottom sediment samples were collected across the entire Lake. The geochemical composition of the sediment samples was determined using X-ray fluorescence (XRF); trace and major elements determined includes As, Pb, Zn, Cu, Ni, Cr, Fe 2 O 3 , TiO 2 , MnO, CaO and P 2 O 5 . The trace elements concentrations of the sediment were grouped into three zones base on their spatial distribution. The Western zone of the lake shows a remarkable enrichment in Nickel (Ni) and Chromium (Cr) and could be associated with geogenic source. However high enrichment of phosphate (P 2 O 5 ) observed in the same zone could be attributed to anthropogenic source, due to agricultural activities on the catchment of Magalies River. Moderate enrichment of As, Zn, Cu, Cr and Pb was recorded in the central zone and could be ascribed to entrapment by fine-grained organic and Fe-rich clay deposit in the central part of the lake; this was showcased by the strong positive correlation between the trace elements and Fe 2 O 3 . As, Zn, Pb and Cu were highly enriched in the South – Eastern zone and anthropogenic source could be responsible for the enrichment due to the influence of the Crocodile River. The average concentration of As, Pb, Zn, Cu, Ni and Cr in the sediment were evaluated by comparison with the upper continental crust (UCC), Shale standard (Turekian and Wedepohl, 1961) and Sediment quality guidelines (SQG); the result indicates that As, Pb, Zn, Cu and Cr in the study area were above the lowest effect level (LEL) but below the severe affect level (SEL) which shows that the impact on biota is moderate. However, Nickel (Ni) was above the severe effect level and could therefore have severe effect on the aquatic environment.

Abstract Interventional oncology (IO) is emerging as a pillar of cancer care in pediatric patients. The minimally invasive techniques employed by IO are increasingly being integrated into the diagnostic, therapeutic, and palliative management of children with cancer. This review provides an evidence-based overview to the endovascular, percutaneous, and supportive and palliative procedures offered by pediatric interventional radiologists. An understanding of the modest but growing literature that supports the safety and efficacy of pediatric IO is important in ensuring the continued adoption of IO in the multidisciplinary care of pediatric cancer patients.


[6, 9], mean that extra caution has always been advised in patients suffering from autoimmune diseases and chronically taking drugs which often cause liver damage (NSAIDs, methotrexate, leflunomide). Several years ago, in 2009, the European League Against Rheumatism (EULAR) issued recommendations about the need to assess the risk of cardiovascular diseases in RA, but also in inflammatory spondyloarthropathies [8]. The recommendations state that the evaluation of the risk can be performed on the basis of cardiac models, e.g. SCORE, taking into consideration the atherogenic index of total cholesterol/HDL-cholesterol. The calculated risk should be multiplied by 1.5 in patients with rheumatoid factor (RF) and/or ACPA, duration of the disease > 10 years and the presence of extra-articular manifestations. It was also established that statins, ACE inhibitors or AT-II receptor blockers should be used in compliance with the national standards. However, the approval of statins does not have a provision allowing their use in the treatment of RA, and all recommendations are based on their activity normalizing the blood cholesterol level. This gives rise to the question whether statins can – and should – be used in the treatment of patients at a high cardiovascular risk and with a reduced total blood cholesterol concentration. Precisely this paradox characterizes the population of patients with active RA [3]. The treatment management guidelines to reduce cardiovascular risk [10] published in 2013 by the American College of Cardiology (ACC) and the American Heart Association (AHA) enumerate four groups of patients who should benefit from an effective statin treatment: • patients with developed atherosclerotic cardiovascular disease, • patients with primary high concentration of LDL cholesterol > 4.9 mmol/l, • diabetic patients aged 40–75 years, • patients without atherosclerosis or diabetes with LDL cholesterol concentration of 1.8–4.9 mmol/l but 10year cardiovascular risk ≥ 7.5%.

Abstract In recent years, Janus amphiphilic nanotubes with complex surfaces have been synthesized. However, the self-assembly behaviour of surfactant solutions confined in a Janus amphiphilic nanotube has not been investigated so far. We performed molecular simulations to investigate the morphologies and phase diagrams of a surfactant confined in Janus amphiphilic nanotube consisting of both hydrophobic and hydrophilic surfaces. We derived a phase diagram of the representative snapshots of equilibrium morphologies. Morphologies that were not observed in the bulk eventuated in confined systems. Moreover, the self-assembled structures were found to be dependent on the spatial confinement. Furthermore, the self-assembled structures confined in hydroneutral and Janus amphiphilic nanotubes were compared. The results suggested that the self-assembled structures confined in the Janus amphiphilic nanotube resembled that confined in the hydroneutral nanotube owing to a strong confinement effect. Further developments in controlling the morphologies and self-assemblies will greatly advance their applications of these materials in nanofluidic devices, or for nanopatterning.


This study proposes an integrated guidance and task assignment methodology to intelligently and smoothly transition from the mid-course to the terminal phase of flight for a many-on-many engagement with a team of aggressors (pursuers) against a team of evaders. More specifically, as the engagements unfold, we develop regions for the pursuers to navigate to based on the concept of Apollonius circles. The goal for the pursuers is to minimize wasted energy from chasing evaders through a zone-based guidance (ZBG) approach, while maximizing end-game intercept through minimization of a cost matrix which balances estimated effort and time-to-go for each pursuer-region pair through user-defined constants. This approach is compared against the same cost matrix without utilizing zones, and against assigning targets a priori. On average, when selecting targets based only on time-to-go, the strategy presented in this work captured the evaders faster, with a smaller cost matrix than the alternative methods.


ABSTRACT To investigate determinants and protective strategies for the resignation of health care workers resulting from patient-derived nuisance in medical institutions, we conducted a cross-sectional survey in the 57 hospitals in Mie Prefecture, Japan. A random sampling of 775 employees (physicians, nurses, administrators, and other health care workers) was provided self-administered questionnaires. Among 480 participants who experienced patient-derived nuisance, 132 participants considered resignation as a result, giving an estimated prevalence of 17.1% (95% CI: 14.4%–19.8%) of all respondents. Nonphysical nuisances such as "demand for an unwarranted apology" (OR: 2.57; 95% CI: 1.61–4.12) had higher ORs for considering resignation than other kinds of nuisance. By contrast, OR for the provision of human support by medical institutions was 0.49 (95% CI: 0.28–0.86). Human support was associated with alleviation of the intention to resign.

Long-term changes in climate can affect human health in myriad ways. Last week, a new report by the U.S. government's climate change science


Dhaincha (Sesbania aculeata) was sown, as an intercrop (one and two rows) between two rows of sugarcane, 30 days after spring planted sugarcane and green manured (in situ) at 45 and 60 days after sowing (DAS). Variations in shoot and root biomass (kg/ha), fresh weight of root nodules (kg/ha) and nitrogen accumulation (kg/ha) in dhaincha were observed. The highest shoot and root biomass and nitrogen accumulation was observed at 60 DAS with 2 rows of dhaincha. Nitrogen application to plant crop of sugarcane produced higher shoot biomass of dhaincha at 225 kg N/ha. Plant crop yield in sugarcane was significantly reduced when two rows of dhaincha intercrop were incorporated (green matured, in situ) at 60 DAS. This was largely due to reduction in biomass and leaf area. Ratoon yield, on the other hand, was significantly increased (5-8%) with dhaincha green manuring in plant crop. Highest ratoon yield was observed with 2 rows of dhaincha intercrop incorporated at 60 DAS. The present study highlights that integrated nutrient management in sugarcane can be practiced by green manuring with dhaincha intercrop and fertilizer N application for sustaining the yield of sugarcane-ratoon system.


We point out a loophole in the derivation of the Bell inequalities in the form proposed by Clauser, Horne, Shimony and Holt (CHSH). In this derivation it is assumed that statistical independence is a necessary consequence of locality, but this is not a logical necessity.


Identifying residual stresses and the distortions in composite structures during the curing process plays a vital role in coming up with necessary compensations in the dimensions of mold or prototypes and having precise and optimized parts for the manufacturing and assembly of composite structures. This paper presents an investigation into process-induced shape deformations in composite parts and structures, as well as a comparison of the analysis results to finalize design parameters with a minimum of deformation. A Latin hypercube sampling (LHS) method was used to generate the required random points of the input variables. These variables were then executed with the Ansys Composite Cure Simulation (ACCS) tool, which is an advanced tool used to find stress and distortion values using a three-step analysis, including Ansys Composite PrepPost, transient thermal analysis, and static structural analysis. The deformation results were further utilized to find an optimum design to manufacture a complex composite structure with the compensated dimensions. The simulation results of the ACCS tool are expected to be used by common optimization techniques to finalize a prototype design so that it can reduce common manufacturing errors like warpage, spring-in, and distortion.


Background The EBSLN is vulnerable to damage during thyroidectomy, results in voice related complications, negatively affect patient quality of life, routine identification of the EBSLN prior to surgical manipulation is necessary for a complication-free thyroidectomy. We aimed to validate a video-assisted procedure for identifying and preserving the external branch of the superior laryngeal nerve (EBSLN) during thyroidectomy and analyze the EBSLN Cernea classification and the localization of the nerve entry point (NEP) from the insertion of the sternothyroid muscle. Methods A prospective descriptive study was performed; 134 patients, who scheduled for lobectomy with an intraglandular tumor max diameter ≤ 4 cm and without extrathyroidal extension, were randomly divided into the video-assisted surgery (VAS) and conventional open surgery (COS) groups. We used the video-assisted surgical procedure for visually identifying the EBSLN directly, and compared the differences in the visual identification rate and total identification rate of the two groups. We also measured the localization of the NEP using the insertion of the sternothyroid muscle as a reference. Results There was no statistically significant difference in clinical characteristics between the two groups. The visual identification rate and total identification rate were significantly higher in the VAS group than the COS group (91.04% vs. 77.61%, 100% vs. 89.6%). The EBSLN injury rate was 0 in both groups. The mean vertical distance (VD) of the NEP from the sternal thyroid insertion was 1.18 mm (SD 1.12 mm, range, 0–5 mm), with approximately 88.97% of the results occurring within the 0–2 mm range. The mean horizontal distance (HD) was 9.33 mm (SD 5.03 mm, range, 0–30 mm), with over 92.13% of the results occurring within the 5–15 mm range. Conclusion Both the visual and total identification rates of the EBSLN were significantly higher in the VAS group. This method provided a good visual exposure rate of the EBSLN, aiding in identifying and protecting the EBSLN during thyroidectomy.


search, nor of how it fits in the current state of the science. One high point of the collection for human factors/ergonomics readers is the Science paper by Alton J. DeLong, who shows how the experience of temporal duration is compressed relative to clock time when an observer looks into scale-model environments. His accompanying commentary on the paper provides the kind of reflective insights only temporal distance produces and is an educated contrast with some other authors' perfunctory remarks. I would have liked a substantive integration of these papers with current environment-behavior research, which could have provided pointers to research outside the MER program and supplied more substantive current commentaries from these authors. But this is primarily a closure festschrift for those who were there. For the rest of us, it is a needed cenotaph to a program that was ahead of its time and that demonstrated the energizing and innovative contributions that derive from interdisciplinary research.


Accurate estimates of riverine constituent loads are essential for water pollution control and erosion control in watersheds, but an accurate estimation method for commonly employed water quality monitoring strategies, such as calendar‐based sampling with high‐flow sampling, has not been established. Therefore, we propose methods for both unbiased load estimation and confidence interval construction for annual riverine loads using the Horvitz‐Thompson estimator based on limited samples (12 to 20 per year) collected with commonly used water quality monitoring strategies. In addition, we propose an uncertainty reduction method to calculate efficient confidence intervals using probability resampling based on a simple rating curve due to the small sample sizes. The effectiveness of the proposed method is verified by load estimates based on 150 annual data sets of daily pairs of discharge and concentration observations of six water quality parameters from different watersheds and years. The tested sampling strategies include random sampling over time as a proxy for calendar‐based sampling, random sampling with high‐flow sampling, and flow‐proportional sampling. The results show that the proposed methods provide unbiased load estimates for all the data sets and appropriate confidence intervals. The uncertainty reduction in the confidence interval widths obtained with probability resampling is effective for calendar‐based sampling. We also explain the importance of defining proper sampling probabilities for load estimation based on samples with missing observations. The proposed method can be used to evaluate and improve existing water quality monitoring strategies for more efficient load estimation and the retrieval of accurate load estimates from existing data sets.


Software development practices which enhance software quality and help teams better develop collaboratively have received attention by the academic community. Among these techniques is Behavior-Driven Development (BDD), a development method which proposes software to be developed focusing primarily on its expected behavior. In this context, this paper investigates how BDD impacts agile software development teams. In order to achieve this, we have conducted a case study on a mobile application development environment which develops software using agile. In total, 42 interviews were performed. Our results indicate that BDD can have positive impacts, increasing collaboration among team members, and negative impacts, like difficulties in writing unit tests. We concluded that BDD has more positive than negative outcomes.


This dissertation deals with the stability of symmetries in quantum mechanics in two important scenarios. First, we study the linear stability of Wigner's symmetry theorem, which is a foundational result on how physical symmetries are mathematically represented. Then, we explore how stable is a symmetry characterization of the important set of Gaussian bosonic states when we allow for small changes in the underlying assumptions.

Constitutions and powersharing arrangements sometimes include provisions designed to promote ethnic, religious, and regional inclusiveness within political parties. Through analysis of a global data set on powersharing provisions, this paper argues that such inclusiveness provisions are often fruitless or even counter-productive, because they are manipulated by ruling elites for their own purposes. The paper draws on examples from Nigeria, Honduras, and Nepal to support and illustrate this argument.


This paper reports development of a new trigger system for a high speed gas gun and experimental results on muzzle speed ofa spherical ceramic projectile launched by a gas gun equipped with the new trigger system. A new trigger system was designed carefully using numerical simulation of interaction between a trigger system and a projectile, and deformation of the trigger system. Launching pressure levels are precisely adjustable by changing trigger system parameters. Calculated launching pressure agreed well with experimental result. It was concluded that a gas gun equipped with this new trigger system can work out more powerful as compared with a commercial air rifle.


During the 2016 U.S. presidential election season, children heard about crowds of angry people shouting, "build the wall" or "go back to your country." In recent months, children of immigrant parents may have witnessed community raids, and many now live in fear that members of their family could be deported. Anxiety in minority communities doesn't stop there. Kids have watched videos of police officers shooting unarmed black men. Such incidents have led to riots and retaliatory violence against policemen and women who serve our towns and cities. Families watched white supremacists march in Charlottesville, Virginia, further heightening racial tensions in America. These divisive events have unsettled our nation. For students of color in particular, these images and this rhetoric underscore the persistent traumatic experience of racism and discrimination.


HE mechanical translation of language has importance, not only in its own right, but also in commerce and industry, both as a means of improving communication and as a pointer to the use of new techniques in data handling and retrieval. This inter-relation between an essentially non-arithmetical process and a normal calculating machine exhibits an important idea: that many processes, thought to be typical of living organisms, can, upon analysis, be reduced to combinations of simple binary decisions and ordinary arithmetic. In 1947 the present author first suggested that the storage organ of a digital calculator could be used to hold a dictionary of words and their foreign language equivalents if these were expressed in suitable numerical code, and also that the logical facilities which the machines contained might be suitable for grammatical processing. EARLY IDEAS Unfortunately no digital computing machine was available in 1947 and in the period between 1947 and 1951 when the first of the machines became available for normal use, the development of machine translation was restricted merely to ideas. The earliest proposals considered only the use of the computing machine as an automatic dictionary, but, in 1948, Booth and Richens produced several methods, all of which involved greater sophistication in the linguistic and data processing techniques. These ideas were tested in some experiments which used punched card machinery for the translation of several languages on a word-for-word basis and form the basis upon which most subsequent work has been modelled. The Americans came comparatively late into the field, the two pioneers being Irwin Reifler at the University of Washington and Y Bar-Hillel at the Massachusetts Institute of Technology. Reifler suggested the pre-editor and the post-editor, the former to remove ambiguities in the foreign language text, for which purpose he need have no knowledge of the language into which translation is to be effected; the latter a technical expert in the subject of translation who would resolve ambiguities and attend to the correct technical phrasing of the results of the machine's operations. Generally the post-editor would be the person for whom the translation was intended. We will not dwell further upon either preor post-editor, since


Biodiversity research generates and uses a variety of data spanning across diverse domains, including taxonomy, geo-spatial and genetic domains, which vary greatly in their structural features and complexities, query processing costs and storage volumes. In this thesis, we present BODHI, a database engine that seamlessly integrates these diverse types of data, spanning the range from molecular to organism-level information. BODHI is a native object-oriented database system built around a publically available micro-kernel and extensible query processor, and offers a functionally comprehensive query interface. The server is partitioned into three service modules: object, spatial and sequence, each handling the associated data domain and providing appropriate storage, modeling interfaces, and evaluation algorithms for predicates over the corresponding data types. To accelerate query response times, a variety of specialized access structures are included for each domain. Our experiments with complex cross-domain queries over a representative biodiversity dataset indicate efficient evaluation even on off-the-shelf standard hardware. BODHI features suffix-tree indexes for expeditious processing of sequence similarity predicates. These indexes are well-known to be not easily amenable to persistent implementation and usage, since their traversal patterns induce severe disk thrashing. To minimize the impact of this problem, we present a suite of optimizations, including: TOP-Q, a novel low-overhead buffer management policy that takes into account the probabilistic behavior of traversals during suffix-tree construction; and STELLAR, a layout-reorganization algorithm that minimizes the cost of suffix-link traversals. Through experimentation on a variety of real genomic and proteomic sequences, we show that the combined effect of these optimizations results in substantially improved index construction and search times. In summary, this thesis presents the architecture and implementation of a holistic and efficient database engine targeted towards helping biodiversity scientists swiftly advance the state-of-the-art in their research.

But how joyfully it is written, and how extensive and scholarly is Hugh Thomas's background knowledge. Chapters xi and xii, on the significance of book ownership amongst the clergy, are particularly good. Anecdote follows anecdote in this valiant and muchneeded attempt to shine a light on the lives of the secular, as opposed to the regular, clergy between the Norman Conquest and the death of John. This is a painstaking task, and not an easy one unless those seculars also happened to be eminent or aristocratic ecclesiastics who appeared in written records. The author has scoured the primary sources thoroughly, both lay and ecclesiastical. Letters and chronicles have been devoured wholesale and with relish, particularly those written by Peter of Blois and Giraldus Cambrensis. The picture is evenhanded in that, alongside plentiful and sometimes shocking tales of, for instance, the drunkenness and sexual incontinence of often poorly-paid lower clergy whose main duty was to serve God and say mass, comes similarly sharp criticism of the simony, nepotism and greed which afflicted some pluralistic higher clergy who should have known better. Indeed, so many seem to have fallen short of the ideal that the picture seems almost biased. It would have been good to have had more examples of those who did not. And the over-use of some phrases simply grates. 'The long twelfth century' – what on earth does this mean? – is used no fewer than eight times, for instance, in the eight-page conclusion. There is quite a bit of repetition. Also, it should perhaps be remembered that the vocation of the priesthood can be fulfilled in innumerable ways. (One wonders what the reformers would have made of those nineteenthand early twentieth-century French clergy who reckoned – probably rightly – that it was a positive pastoral service to found brass bands or football teams to keep their young flocks out of mischief.) But these are exceedingly small quibbles. Overall, Thomas's book is a treasury of knowledge and a delight to read.


There was suggested an idea of integrated structures in the industry of Belarus. Making of, in borders operated, concern "Bellegprom" holdings in trade appliance will allow to unit intellectual potential of specialized industry segments, consolidate material, financial and human resources for achievement of priority of economics development, and get synergetic effects.


One of the most remarkable revivals in all Christian history has been in progress since World War I. It is a revival of intensive Bible study and a renaissance of thoroughgoing Biblical theology. Many theologians have ventured to identify the opening signal of this movement with the publication of Karl Barth's Romerbrief, his commentary on Paul's Epistle to the Romans, in 1918.1 This "bombshell"2 in the theological world was not an adequate commentary on the Roman epistle, but it recovered the meaning of "the word of God" with a depth and dimension which was desperately needed in this century of crisis. So central is his understanding of "the Word of God" in all of his theological formulation that Barthian theology is often called the "Theology of the Word of God."3 For the subject under consideration in this article, it is even more significant that Karl Barth recovered this Pauline and New Testament understanding of the word of God under the urgent necessity of finding an authentic message to preach to his church in the Alpine village of Safenwil. He often prepared his sermon for Sunday against the background noise of the pounding guns on the French-German battlelines of World War I. How foolish and irrelevant were the words of the liberal theology in which he had been trained! In the face of human sin, hatred, and war, in the midst of a troubled and distraught people, he desperately needed a "word from the eternal."4 Like Augustine and Luther, Barth found this "word" as he toiled with anguish of soul through Paul's epistle to the Romans. The word of God had broken through into his heart and life; the people of Safenwil knew that something had happened to their

approved: Redacted for Privacy Dr. James G. Knudsen Scaling characteristics on plain and finned tubes in a deluged dry cooling system were investigated. For all runs in this study drying and deluge times were held constant at 10 and 5 minutes respectively, water flow was 350 ml/min, and air velocity past the test section was 1.1 m/s. Simulated cooling tower water containing various corrosion inhibitor additives, and city water were used as delugates. Heat fluxes of 41.12, 49.34, 57.56 w/dm2 were used. Scaling on the plain tube test section was confined mainly to the lower half of the horizontal tube. End effects may have enhanced scale formation near the tube ends. Results suggest an asymptotic deposit might be reached, but more data are needed to verify this. Scaling on the horizontal finned tube was confined mainly to the lower fin ridges, and the bottom base and fin faces. Asymptotic deposit values of 93 g/dm 2 at 49.34 w/dm 2 , and 199 g/dm 2 at 57.56 w/dm2 were observed. The finned tube test section was found to scale at a much faster rate than the plain tube test section. There was better heat transfer on the finned tube under drying conditions, while the plain tube had better heat transfer under deluged conditions. The data were fitted to four different two parameter equations. A modified Kern-Seaton deposit removal type equation, m = m* (1 exp(-C/6 c )) was found to fit the simulated cooling water runs best over the number of cycles studies. When city water was used as a delugate corrosion on the heat transfer surface occurred. The amount of deposition was found to be proportional to the number of deluge cycles.

Astrocytes play active roles at synapses and can monitor, respond, and adapt to local synaptic activity. To investigate this relationship, more tools that can selectively activate native G protein signaling pathways in astrocytes with both spatial and temporal precision are needed. Here, we tested AAV8-GFAP-Optoα1AR-eYFP (Optoα1AR), a viral vector to enable activation of Gq signaling in astrocytes via light-sensitive α1-adrenergic receptors. To determine if stimulating astrocytic Optoα1AR modulates hippocampal synaptic transmission, recordings were made in CA1 pyramidal cells with surrounding astrocytes expressing Optoα1AR, channelrhodopsin (ChR2), or GFP. Both high-frequency (20 Hz, 45-ms light pulses, 5 mW, 5 min) and low-frequency (0.5 Hz, 1-s pulses at increasing 1, 5, and 10 mW intensities, 90 s per intensity) blue light stimulation were tested. 20 Hz Optoα1AR stimulation increased both inhibitory and excitatory postsynaptic current (IPSC and EPSC) frequency, and the mIPSC effect was largely reversible within 20 min. By contrast, low-frequency stimulation of Optoα1AR did not modulate either IPSCs or EPSCs, whereas the same stimulation of astrocytic ChR2 was effective. These data demonstrate that Optoα1AR activation in astrocytes changes synaptic excitation and inhibition in a stimulation-sensitive manner, demonstrating the efficacy and utility of GFAP-Optoα1AR as a tool in studying astrocyte-neuron interactions.


Although indirect, studies of repair mechanisms afford a useful approach to the questions: Where and what are the sensitive sites in a cell related to division? This approach has been used with mammalian cells based on the fact that sublethal damage must be accumulated to kill a cell and the observation that cells can repair sublethal damage. Actinomycin D was found to inhibit this repair, an observation which justified a focus upon nuclear DNA as the site of damage and repair. Sedimentation studies with alkaline gradients revealed two repair processes. Repair of single-strand breaks (also found by others) and repair to a complex of DNA, lipid, and protein. In cells sensitized to fluorescent light because of prior growth in the presence of 5-bromodeoxyuridine, the data suggest that single-strand breaks is the lethal lesion. In contrast, damage to a DNA-membrane structure appears a more likely target for X-ray cell killing.


In this paper, an efficient modification of nonlinear conjugate gradient method and an associated implementation, based on an exact line search, are proposed and analyzed to solve large-scale unconstrained optimization problems. The method satisfies the sufficient descent property. Furthermore, global convergence result is proved. Computational results for a set of unconstrained optimization test problems, some of them from CUTE library, showed that this new conjugate gradient algorithm seems to converge more stable and outperforms the other similar methods in many situations.


The Eurasian beaver (Castor fiber L.) is the largest free-living rodent in Eurasia. Beavers show seasonal patterns of reproduction (long-day breeders), stress reactions, and feeding behavior. These phenomena are associated with the function of hormonal regulatory axes: the hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary-gonadal (HPG). In mammals, the above processes are also controlled by orexins (OXA and OXB), neuropeptides derived from the same precursor—prepro-orexin (PPO). We hypothesized that in beavers PPO gene expression in tissues creating the HPA-HPG axes and plasma orexin concentrations differ between seasons and sexes. PPO transcript and PPO and orexin proteins were noted in the mediobasal hypothalamus (MBH), pituitary, adrenals, and gonads in April ("breeding, pregnancy"), July ("post-breeding"), and November ("pre-breeding"). In the MBH, seasonal, but not sex-dependent variations were observed in PPO gene expression; however, the transcript content increased in females in July. An interaction between season and sex was noted in the pituitary: PPO gene expression decreased in males in April. The PPO mRNA concentration in adrenals varied between seasons and sexes. Additionally, an interaction between these factors occurred and the highest PPO gene expression was noted in females in April. In the gonads, PPO mRNA levels changed dependent on season, and an interaction between season and sex was found. The PPO transcript increased in November in the testes. Seasonal variations and an interaction between season and sex were observed in plasma OXA. The highest concentration of OXA was noted in July (males) and in November (females). In beavers, PPO gene expression and plasma OXA concentration varied depending on season and these changes were modified by sex. Our results imply that orexin peptides are involved in the regulation of circannual changes of reproductive activity in beavers and seem to be associated with seasonal fluctuations in glucocorticoid secretion and stress reactions.


Dependence of the tensile strength of resulting carbon fiber (CF) on the preparation technologies during preoxidation and carbonization were studied systematically by a series of pilot experiments. The proper preoxidation time, preoxidation temperature, and preoxidation stretching ratio are the base of preparing high-quality CF. During precarbonization, the enhancement of the precarbonization temperature and the application of the precarbonization stretching are helpful to increase the tensile strength of CF, but the stretching ratio should be controlled carefully by on-line tension values. The tensile strength of CF increases quickly below 1200°C and then slowly above 1200°C as the carbonization temperature raises. Even though during carbonization, a proper relaxation should also be explored in order to prepare optimal CF. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008


Nifursol (3,5-dinitrosalicylic acid (5-nitrofurfurylidene) hydrazide) is mainly used as a feed additive for the prevention of blackhead disease in turkeys. The objective of the present work was to establish information on nifursol residues in turkey and chicken meat. The analytical method was based on conversion of nifursol and its metabolites with an intact 3,5-dinitrosalicylic acid hydrazide (DNSH) side chain to the 2-nitrophenyl analogue of nifursol (NPDNSH) by treatment with dilute hydrochloric acid and 2-nitrobenzaldehyde. Nifuroxazide (salicylic acid (5-nitrofurfurylidene) hydrazide) added as an internal standard was converted to the 2-nitrophenyl analogue NPSH. After the addition of ammonia, proteins were precipitated with acetonitrile. Chromatographic separation was achieved on a C18 column and negative-ion electrospray ionization mass spectrometry was employed using m/z 183 and 226 (daughter ions of the NPDNSH phenolate ion m/z 374) for quantification and m/z 93 (daughter ion of the NPSH phenolate ion m/z 284) as a retention time reference. The decision limit (CCα) and detection capability (CCβ) of the analytical method were 0.05 and 0.08 µg kg−1, respectively. In the range 0.5–1 µg kg−1, the repeatability, within-laboratory reproducibility and trueness were 8, 11 and −1%, respectively. A total of 37 samples of turkey meat and 16 samples of chicken meat were purchased at retail outlets in early spring, summer and winter 2003, and analysed for nifursol residues. No residues were found in the chicken samples, but nine of 18 samples of turkey meat collected in the spring had between 0.05 and 0.6 µg kg−1 (average 0.25 µg kg−1) nifursol residues.


Polytherms of kinematic viscosity of nickel-based alloys with Cr, Si, Fe and B additives have been studied. It was found out that the first liquid phase volumes appear when temperatures are well below the tabular values of the solidus temperature ts. The critical temperature of the alloy was defined. The ways of obtaining materials of higher amorphization ability were suggested.


Analysis of quinine in plasma and whole blood samples dried on filter paper is described. Sample preparation involves liquid extraction of plasma and whole blood from the filter paper and subsequent solid‐phase extraction using C8 Bond Elut cartridges. A reverse‐phase liquid chromatography system with UV detection and fluorescence detection was used. The analytical characteristics of the method are reported, with a quantification limit of 0.1 µg mL−1 and within an assay coefficient of variation of 5.6–8.4% in plasma and 6.5–12% in whole blood. Representative chromatograms are shown as a function of time for samples from human subjects after ingestion of a single 400‐mg dose of quinine sulphate. Quinidine, dihydroquinine and metabolites are well separated from quinine with a resolution of above 1 (Rs>1). Copyright © 2000 John Wiley & Sons, Ltd.

Radio frequency interference (RFI) is an increasing concern for radio astronomers as demand for spectrum grows and new technologies are adopted. A particularly pernicious type of RFI is unintentional RFI. Unintentional RFI is generated by devices such as mechanical relays as a byproduct of their normal operation. This type of RFI is difficult to identify because it is usually transient, intermittent and broadband. Some important astronomical sources, such as pulsars, also emit transient signals; thus there is a need to distinguish between these sources and RFI. Here we show how a time domain RFI classification method investigated previously can be adapted to distinguish between pulsar signals and transient RFI. We demonstrate this by applying the method to time domain recordings of transient RFI events and pulsar observation data.


There is a vast literature documenting the geography of start-ups and their impact on regional economic development. A shortcoming of many studies is their focus on the frequency of start-ups rather than the characteristics of start-ups. Understanding the heterogeneity in start-ups is important as it may explain why the economic effect of start-ups differ across the urban hierarchy. This chapter provides an explorative account of differences in the characteristics of start-ups across the urban hierarchy in Sweden. We find evidence that the difference between urban and rural entrepreneurship is manifest particularly in a skill gap in entrepreneurship.


The electronic structure of two ethene molecules and two allyl radicals in the presence of an alkali atom are studied using ab initio methods as a simplified model of electron transfer (ET) for an alkali‐dopant site for ET in polyacetylene. At the optimized structure the systems are stable charge transfer complexes, where the charge is transferred to one of the monomers. Parameters of interest for the understanding of electron transfer steps in alkali doped polyacetylene, such as reorganization energy and electronic factor for ET, are calculated. We find for the two systems studied here an important additional contribution to the reorganization energy for ET between the chains (about 0.40 eV) due to the motion of the alkali ion.

This paper shows a method for building and publishing datasets in commercial services. Datasets contribute to the development of research in machine learning and recommender systems. In particular, because recommender systems play a central role in many commercial services, publishing datasets from the services are in great demand from the recommender system community. However, the publication of datasets by commercial services may have some business risks to those companies. To publish a dataset, this must be approved by a business manager of the service. Because many business managers are not specialists in machine learning or recommender systems, the researchers are responsible for explaining to them the risks and benefits. We first summarize three challenges in building datasets from commercial services: (1) anonymize the business metrics, (2) maintain fairness, and (3) reduce the popularity bias. Then, we formulate the problem of building and publishing datasets as an optimization problem that seeks the sampling weight of users, where the challenges are encoded as appropriate loss functions. We applied our method to build datasets from the raw data of our real-world mobile news delivery service. The raw data has more than 1,000,000 users with 100,000,000 interactions. Each dataset was built in less than 10 minutes. We discussed the properties of our method by checking the statistics of the datasets and the performances of typical recommender system algorithms.


Economic activity is the basis of the whole social harmony,while the basic point for the harmony of economic activity is to deal with the relationship between efficiency and equality properly.Realizing the union between efficiency and equality is the basis for constructing socialist harmonious society in our country.The Fifith Plenary Session of the 16th CCP of China pointed out,"modulating income division reasonably","laying emphasis on social equality"specially.Facing the new situation which is caused by inequality,that is,the polarization of rich and poor affects the whole social harmony,we should adjust the policy on the relationship between efficiency and equality,and adopt the principle"efficient equality as well as attaching imporatnce to others".We can take some specific measures to promote the construction of harmonious society.The measures are shown as follows:continue to lay emphasis on the reform and development;further regulate the division rule of income;construct the central and western cities fast;try to add the farmers' income;develop the government effective function on re-division;speed up foundation of perfect social security system,etc.


As an alternative concept for glycosylation, the prior activation of acceptor hydroxy groups for selective glycosidic bond formation, was investigated to give complex oligosaccharides. Oxyanions obtained from partially protected saccharides were glycosylated by employing glycopyranosyl halides, and the regiochemical results were studied. Initially, partially methylated methyl-α-D-glucopyranosides were used as a model system to study the underlying mechanistic principles of base-promoted glycosylation. High regioselectivities and stereospecific glycosidic bond formations were achieved, and the scope of the methodology was extended with different perbenzylated glycosyl donors.


Knowledge representation learning is representing entities and relations in a knowledge graph as dense low-dimensional vectors in the continuous space, which explores the features and properties of the graph. Such a technique can facilitate the computation and reasoning on the knowledge graphs, which benefits many downstream tasks. In order to alleviate the problem of insufficient entity representation learning caused by sparse knowledge graphs, some researchers propose knowledge graph embedding models based on instances and concepts, which utilize the latent semantic connections between concepts and instances contained in the knowledge graphs to enhance the knowledge graph embedding. However, they model instances and concepts in the same space or ignore the transitivity of isA relations, leading to inaccurate embeddings of concepts and instances. To address the above shortcomings, we propose a knowledge graph embedding model that differentiates concepts and instances based on spatial transformation—CIST. The model alleviates the gathering issue of similar instances or concepts in the semantic space by modeling them in different embedding spaces, and adds a learnable parameter to adjust the neighboring range for concept embedding to distinguish hierarchical information of different concepts, thus modeling the transitivity of isA relations. The above features of instances and concepts serve as auxiliary information so that thoroughly modeling them could alleviate the insufficient entity representation learning issue. For the experiments, we chose two tasks, i.e., link prediction and triple classification, and two real-life datasets: YAGO26K-906 and DB111K-174. Compared with state of the arts, CIST achieves an optimal performance in most cases. Specifically, CIST outperforms the SOTA model JOIE by 51.1% on Hits@1 in link prediction and 15.2% on F1 score in triple classification.

ABSTRACT

Welding fumes are composed of fine and ultrafine particles, which when it gained access to the body system either via inhalation or as food or water contaminants can elicit various haematological and biochemical changes. In order to determine the haematological changes elicited by welding fumes and it's mitigation by ascorbic acid, a total of fifteen male Wistar rats were randomly divided into three groups (A, B and C) of five animals per group. Group A served as the control while group B were kept in enclosed welding environment for adequate inhalation of the welding fume. Group C were equally kept in the enclosed welding environment but were daily orally administered 100mg of ascorbic acid for two weeks. At the end of two weeks of exposure, blood samples were obtained for haematological analyses. It was observed that exposure to the welding fumes predisposes the rats to macrocytic hypochromic anaemia and stress with evidence of neutrophilia and lymphopenia. These observed haematological perturbations were reversed by ascorbic acid back similar to that of the control group. It can be concluded that haematological perturbation induced by welding fume can be mitigated effectively by ascorbic acid without any deleterious effects.


Energy conservation and emission reduction are important ways to cope with global warming. An analysis of energy conservation and emission reduction from the perspective of network infrastructure construction provides an important perspective for the study of sustainable development. Based on the research sample of 263 cities in China from 2006 to 2019, and taking the policy of "Broadband China" as a quasi-natural experiment, this paper uses the double difference model to evaluate the impact of network infrastructure construction on energy conservation and emission reduction. The results show that (1) the construction of network infrastructure can significantly improve the energy utilization rate and reduce carbon emissions intensity, which helps to promote energy conservation and emission reduction. (2) From the perspective of a functional mechanism, on the one hand, network infrastructure construction affects energy conservation and emission reduction through micro-mechanisms such as green technology innovation and energy efficiency. On the other hand, network infrastructure construction also drives the development of the Internet and the digital economy, and promotes energy conservation and emission reduction through macro-mechanisms such as industrial structure and financial development. (3) The heterogeneity analysis shows that network infrastructure construction in non-resource-based cities, eastern regions and low-carbon cities has a greater impact on energy conservation and emission reduction. This study provides a new perspective for achieving low-carbon development goals.


The 'Who pays for our Common Wealth' report into tax contributions by the S and P ASX 200, Australia's 200 top stockmarket listed companies, has found that 84% of them paid less than the company tax rate of 30% in the period between 2004 and 2013. This amounts to $80 billion in forgone taxation revenue.


A 57 y/o female presented with sudden onset of transient right homonymous hemianopsia while driving. Later the same day she also reported a 3–4 h period of decreased cognitive ability, being unable to perform calculations. She was seen in the emergency room and underwent neuroimaging studies. MRI demonstrated a 25.9 3 23.6 3 21.3 mm round, slightly lobulated, mass within the suprasellar cistern with significant mass effect. A preoperative T1-weighted sagittal image without contrast showed a suprasellar mass, isointense to the brain cortex with compression and superior displacement of the optic chiasm and floor of the third ventricle (Figure 1A). The inferior margin of the mass was in contact with the dorsum sella and posterior aspect of the diaphragm sella. No intrasellar extension was seen. The posterior margin extended into the region of interpeduncular cistern with associated splaying of the cerebral peduncle. T1-weighted gadolinium-enhanced sagittal images demonstrated homogenous enhancement. Normal pituitary gland is seen within the sella turcica, independent of the lesion. There is no enlargement of the sella turcica (Figure 1B) T2-weighted coronal image shows low signal intensity of the mass (Figure 1C). The patient underwent a right fronto-temporoparietal stereotactic craniotomy for resection of the lesion.


AKR1B10 is a human NADPH-dependent aldo-keto reductase family 1 B10, which has been considered as a potential cancer therapeutic target. 3,5-O-Dicaffeoyl-epi-quinic acid (3,5-DCQA) was isolated from ethyl acetate fraction of Gymnaster koraiensis (Nakai) Kitam as an AKR1B10 inhibitor. 3,5-DCQA inhibited the activity of recombinant human AKR1B10 (rhAKR1B10) with its IC50 value of 1.2 μM and its inhibition mode was uncompetitive from enzyme kinetic analysis.


When the entire image is divided into regions, each of which is subjected to predictive encoding while predicting an image signal by using an independent method assigned to the region, the object number and a representative pixel value for each object are predicted utilizing spatial continuity for the presence of the object, and also using decoded pixel values of a previously-processed neighbor region adjacent to a processing region. Accordingly, it is possible to reduce the amount of code required for encoding the object number in the processing region or the pixel value as a representative of each object in the processing region, where these encoded items are required in highly accurate image signal prediction which can handle any object shape by utilizing the pixel value as a representative of each object in the processing target region and information for identifying the object assigned to each pixel in the processing region. Therefore, efficient image encoding can be implemented. Since the employed decoded pixel values of pixels in a previously-decoded neighbor region are common information between the encoding and decoding sides, appropriate prediction can be performed even in the case where one of multiple image signal prediction modes is selected for each region, like in H.264.


Painful processing procedures in piglets such as tail docking, castration and teeth clipping are an emerging animal welfare concern. We hypothesized that transmammary delivery of a non-steroidal anti-inflammatory drug, firocoxib, would reduce pain associated with processing in piglets. The first study compared the pharmacokinetics, efficacy, safety and tissue residue concentrations of four doses of firocoxib (0.5, 1.0, 1.5, or 2.0 mg/kg) administered to sows and delivered to nursing piglets prior to processing. Sixteen sows, 5±2 d postpartum, were randomly assigned to one of four treatment groups. On d 0 sows received a single intramuscular dose of firocoxib at 7±1 h before piglet surgical castration, tail docking, and teeth clipping (males) or sham handling (females). Firocoxib, cortisol and prostaglandin E2 (PGE2) concentrations were determined from selected samples collected from sows and three piglets/litter (two barrows and one gilt) at 0, 2, 4, 6, 8, 12, 24, 48, 72, 96, and 120 h after drug administration. On d 21, piglets were weighed and all animals were euthanized and necropsied. Tissues were collected from 3 piglets/litter for histological examination and drug residue analysis. Mean (±SEM) peak plasma firocoxib concentrations (Cmax) were 107.90±15.18, 157.50±24.91, 343.68±78.89, and 452.83±90.27 ng/mL in sows receiving 0.5, 1.0, 1.5, and 2.0 mg/kg firocoxib, respectively, and 9.53±1.21, 31.04±6.79, 53.30±11.1, and 44.03±7.47 ng/mL in their respective piglets. Mean plasma terminal half-life values ranged from 26 to 31 h in sows and 30 to 48 h in piglets. Barrows nursing sows that received 2.0 mg/kg firocoxib had a lower mean plasma cortisol concentration at 1±1 h after processing compared to barrows nursing sows that received 1.0 mg/kg (P=0.0416) and 0.5 mg/kg of firocoxib (P=0.0397). Piglets nursing sows that received 1.5 mg/kg firocoxib had consistently the lowest concentrations of circulating PGE2 suggesting inhibition of the cyclooxygenase enzyme by firocoxib. From processing to weaning, litters of sows receiving 2.0 mg/kg firocoxib gained more weight than litters of sows that received 0.5 mg/kg (P=0.008) or 1.0 mg/kg (P=0.005). No signs of NSAID toxicity were observed on examination of the kidney, liver, stomach and small intestine and concentrations of firocoxib and the descyclopropylmethyl metabolite were below the limit of detection (0.01 μg/g) in all tissues examined from sows and piglets. These findings indicate that maternal delivery of firocoxib to suckling piglets before tail docking and castration may safely reduce processing-induced stress and enhance production by increasing weaning weights. The second study evaluated changes in cranial skin and ocular temperature, assessed using infrared thermography (IRT), and gait, assessed using a pressure mat, as biomarkers of pain in piglets after transmammary


(1) Effects of density on various growth parameters of Drosophila melanogaster were studied. Pre-adult survival decreased with pre-adult density, and adult fecundity decreased with both pre-adult density and adult crowding. (2) These three effects were used to construct a model of density-dependent population dynamics. The model predicts the number of pre-adults for each generation in a population with two life stages and non-overlapping generations. (3) Twenty-five experimental populations of D. melanogaster of small size and nonoverlapping generations were maintained in vials for nine generations. The numbers of eggs and adults were counted each generation. These numbers showed sustained and erratic fluctuations. (4) A deterministic version of the dynamical model predicts rapid approach to equilibrium and cannot explain such fluctuations. (5) The predictions of a stochastic version of the dynamical model, however, agree with the observed behaviour of the experimental populations: the frequency distribution of the mean population size (MPS), and the square root of the mean squared deviation of population size from MPS, do not show a statistically significant deviation from those predicted by the stochastic model. Thus, the oscillations in numbers of the experimental populations are interpreted as a consequence of random fluctuations.


The paper deals with control algorithm for nonlinear single input single output (SISO) plants under unknown parameters, external disturbances and unknown time delay. The control system is used one filter of dimension n, where n is a dynamical order of the plant. The derivatives of stabilizing controls are implemented by first order observers. The proposed algorithm ensures the small difference between output of the plant and the reference signal. Simulations illustrate an efficiency of proposed scheme for an unstable nonlinear plant with time delay.

The invention discloses a method for preparing stainless steel fiber resin matrix composite conductive plastics. A resin material contains stainless steel fibers accounting for 3-40% of the overall weight, epoxy emulsion and silane coupling agent compound treating fluid are used as interface compatilizers, and a resin material layer is uniformly coated on a stainless steel fiber surface, so that the stainless steel fiber resin matrix composite conductive plastics are prepared. The method includes the steps: performing surface treatment for the stainless steel fibers by the aid of the epoxy emulsion and the silane coupling agent compound treating fluid and drying the stainless steel fibers in a drying oven; pulling out the stainless steel fibers by the aid of a coating die to coat the resin material on the stainless steel fiber surface; and dicing the stainless steel fibers into particles by the aid of a dicing cutter to obtain particles of the stainless steel fiber resin matrix composite conductive plastics. The conductive plastics prepared by the method have excellent mechanical performance and electrical conductivity, and the lowest volume resistivity can be 10-1omega.cm. Coaxial flange method test results indicate that the electromagnetic shielding property of the conductive plastics with the thickness of 2mm ranges from 40dB to 65dB within the frequency range from 30MHz to 1000MHz.

In this paper, we present a novel recognition algorithm for detecting tongue cancer stem cells with respect to appropriate scaling factors. Our method can be achieved by computer image processing in the condition that the cancer cells are undifferentiated or slightly differentiated, which is of important research significance in the realm of oral medicine. According to the biological natures of tongue cancer stem cells, we select the curvature variance of cell contour, the nuclear-cytoplasmic area ratio, and the average optical density of cytoplasm as the measurement parameters. Using these three biological parameters, the characteristics of cancerous tumor cells can be described and thus classified. Therefore, those cells can be categorized under the principle of maximum degree of membership in fuzzy pattern recognition algorithms. In this way, the tongue cancer stem cells can be automatically detected. Desirable recognition results given by our experiments have substantiated the efficiency of our algorithm.


As a major source of energy, wireless Internet of Things (IoT) endpoints rely on batteries. The batteries are short-lived, large in size, and bulky. But the most important thing is that batteries are extremely harmful to the environment. This necessitates the use of battery-free devices, which provide a promising alternative to a sustainable and stable IoT, where the energy collected from the environment is stored in systems of supercapacitors or ultracapacitors. Limited storage of collected energy and the unpredictability of collected energy lead to periodic behavior when the device is turned on and off. Measuring and understanding the current consumption and execution time of various tasks of IoT applications is crucial for the proper operation of these devices without batteries. In this article, we report a successfully designed and tested wireless LoRaWAN end sensor node without battery for IoT applications. The fundamental feature is the realized extremely low value of energy consumption that allows using supercapacitor and solar harvesting energy to power the microcontroller and sensors. We use a LTC3588 nano power energy harvester IC, solar panel and supercapacitor to power the wireless sensor node.


The overall objectives of the project were two fold: 1) the development of new facile reactions for coupling radioactive complexes with biomolecules and 2) the development of a novel molecular imaging targeting vector for Prostate Specific Membrane Antigen (PSMA) for prostate cancer. The didactic approach allowed the synergistic exploration of new technologies for coupling reactions of radioactive complexes that can be applied to a novel targeting moiety. As part of the project, a number of students (undergraduate, graduate and post-doctoral) were trained in radiochemical techniques for preparing and characterizing radiometal complexes. Results from the experiments within the project have generated several presentations and publications.


Orthogonal frequency-division multiplexing (OFDM) is a popular transmission technology in cognitive radio (CR) networks, because the correlation of cyclic prefix (CP) in OFDM signals can be utilized to improve the reliability of spectrum sensing of secondary users (SUs). However, the optimal spectrum sensing over multipath fading channels remains an important and challenging issue. Therefore, this work proposes an optimal Neyman- Pearson (NP) detector for spectrum sensing using CP. To detect the OFDM signal of primary users (PUs), the log- likelihood ratio (LR) test is formulated by using the correlation characteristics of the redundancy of CP. Analytical results indicate that the LR of received samples is equivalent to their log- likelihood function (LF) plus LR of an energy detector (ED), subsequently allowing us to gain insights on the optimal NP detector. Since many unknown parameters need to be resolved, a practical generalized log-likelihood ratio test (GLRT) is presented. Moreover, to achieve a good performance over multipath fading channels, a channel- independent GLRT (CI-GLRT) is employed to derive an estimation of correlation coefficient independent of multipath channel profiles. Simulations confirm the advantages of the proposed detectors compared with state-of-the-art detectors.


As a manufacturer of optical systems for space applications, Sodern is faced with the necessity to design optical systems which image quality remains stable while the environment temperature changes. Two functions can be implemented: either a wavefront control or the athermalization of the optical system. In both cases, the mechanical deformations and thermal gradients are calculated by finite-element modeling with the IDEAS NX7 software. The data is then used in CODE V models for wavefront and image quality evaluation purposes. Two cases are presented: one is a UV beam expander in which a wavefront control is implemented and the other is an athermalized IR camera. The beam expander has a wavefront–tuning capability by thermal control. In order to perform the thermo-optical analysis in parallel with the opto-mechanical development, the thermo-optical modeling is done step by step in order to start before the mechanical design is completed. Each step then includes a new modeling stage leading to progressive improvements in accuracy. The IR camera athermalization is achieved through interaction between the mechanical CAD software and the optical design software to simulate the axial thermal gradients, radial gradients and all other thermal variations. The purpose of this paper is to present the steps that have led to the final STOP (Structural, Thermal Optical) analysis. Using incremental accuracy in modeling the thermo-optical effects enables to take them into account very early in the development process to devise all adjustment and test procedures to apply when assembling and testing the optical system.

A modified Monte Carlo method combined with quenched molecular dynamics simulation is used to determine mixing energetics and concentration profiles at interface for systems containing mono-and bilayers of adatoms adsorbed on FCC (100) crystal surface. The systems under consideration are constructed via Lennard–Jones potential at temperatures near 0 K. For systems with monolayer of adatoms, intermixing at the interface becomes preferable with increasing magnitude of the potential well-depth ratio of adatom to substrate atom. The increasing tendency of intermixing is linearly enhanced when the adatom becomes smaller than the substrate atom, otherwise, the intermixing trend is non-linear and weaker. For systems with bilayers of adatoms, complex development of concentration profile is observed along with increasing magnitude of the potential well-depth ratio and atomic size difference between adatom and substrate atom. This behaviour is related to the interplay between contributions of asymmetric bond interaction and relaxation to minimise the total energy of the system.


In the Manifesto of the Communist Party Marx and Engels wrote: 'The bourgeoisie cannot exist without constantly revolutionizing the instruments of production, and thereby the relations of production, and with them the whole relations of society.' Marx thought enough of these words to reproduce them in Capital. Much of what has been written by Marxists since Marx has been to document that statement, but not always with an understanding of its total meaning. Some writers complain, a century after his death, that Marx did not document the working out of his predictions. What this position reflects is an unwillingness to understand and use Marx's methodology, as Lenin did in his work on imperialism.


The evaporation process of charged droplets with different conductivity is experimentally studied in details. By means of high-speed microscopy camera, the evaporation characteristics including contact angle and height of a charged droplet under different applied voltages have been visualized and measured. According to the characteristics, the charged evaporating process is concluded by us as two stages: the stationary stage and the accelerated stage. The study reveals that electric field significantly influenced the evaporation of droplets and need to be considered when quantifying the evaporation process. The evaporating time of water droplet is almost double the time of hydrochloric acid (HCl) droplet at the same voltage. The evaporating rate increases dramatically with the increase of the voltage. The ion concentration of charged droplets is also shown to have a significant effect on internal circulations. The results indicate that electrical force promotes the movements of ions which determine the evaporation rate of charged droplets. It is assumed that micro electro-hydro Dynamics (EHD) such as the droplet internal flows have large impact on the evaporation process of charged droplets.
