LINK PREDICTION USING DISCRETE-TIME QUANTUM WALK

Original scientific paper Link prediction is one of the key issues of complex networks, which attracts much research interest currently. Many link prediction methods have been proposed so far. The classical random walk as an effective tool has been widely used to study the link prediction problems. Quantum walk is the quantum analogue of classical random walk. Numerous research results show that quantum algorithms using quantum walk outperform their classical counterparts in many applications, such as graph matching and searching. But there have been few studies of the link prediction based on quantum walk, especially on discrete-time quantum walk. This paper proposes a new link prediction method based on discrete-time quantum walk. Experiment results show that prediction accuracy of our method is better than the typical methods. The time complexity of our method running on classical computers, compared with the methods based on classical random walk, is slightly higher. But our method can be greatly accelerated by executing on quantum computers.
Modal Formulas True at Some Point in Every Model

In a paper on the logical work of the Jains, Graham Priest considers a consequence relation, semantically characterized, which has a natural analogue in modal logic. Here we give a syntactic/axiomatic description of the modal formulas which are consequences of the empty set by this relation, which is to say: those formulas which are, for every model, true at some point in that model.
Perspective – synthetic DEMs: a vital underpinning for the quantitative future of landform analysis?

Abstract. Physical processes, including anthropogenic feedbacks, sculpt planetary surfaces (e.g. Earth's). A fundamental tenet of geomorphology is that the shapes created, when combined with other measurements, can be used to understand those processes. Artificial or synthetic digital elevation models (DEMs) might be vital in progressing further with this endeavour in two ways. First, synthetic DEMs can be built (e.g. by directly using governing equations) to encapsulate the processes, making predictions from theory. A second, arguably underutilised, role is to perform checks on accuracy and robustness that we dub "synthetic tests". Specifically, synthetic DEMs can contain a priori known, idealised morphologies that numerical landscape evolution models, DEM-analysis algorithms, and even manual mapping can be assessed against. Some such tests, for instance examining inaccuracies caused by noise, are moderately commonly employed, whilst others are much less so. Derived morphological properties, including metrics and mapping (manual and automated), are required to establish whether or not conceptual models represent reality well, but at present their quality is typically weakly constrained (e.g. by mapper inter-comparison). Relatively rare examples illustrate how synthetic tests can make strong "absolute" statements about landform detection and quantification; for example, 84 % of valley heads in the real landscape are identified correctly. From our perspective, it is vital to verify such statistics quantifying the properties of landscapes as ultimately this is the link between physics-driven models of processes and morphological observations that allows quantitative hypotheses to be tested. As such the additional rigour possible with this second usage of synthetic DEMs feeds directly into a problem central to the validity of much of geomorphology. Thus, this note introduces synthetic tests and DEMs and then outlines a typology of synthetic DEMs along with their benefits, challenges, and future potential to provide constraints and insights. The aim is to discuss how we best proceed with uncertainty-aware landscape analysis to examine physical processes.
INTRODUCING "BOMBTURBATION," A SINGULAR TYPE OF SOIL DISTURBANCE AND MIXING

This article introduces the term "bombturbation" for cratering of the soil surface and mixing of the soil by explosive munitions, usually during warfare or related activities. Depending on exactly where the explosion occurs (above, on, or below the soil surface), bombturbation excavates a volume of soil from the site of impact, forming a crater and spreading much of the ejecta out as a surrounding rim of mixed, but sometimes slightly sorted, debris. Because such explosions are nonselective, that is, all of the material removed is mixed and redistributed, bombturbation is often a proisotropic form of pedoturbation-causing existing soil horizons to be entirely destroyed or intimately mixed. Although anthropogenically linked, bombturbation fits most appropriately under the existing pedoturbation category of "impacturbation. " Unlike the rare instances of extraterrestrial (meteoroid) impacts, impacturbation by bombs and munitions is common worldwide; on some battlefields, it is so prominent that little or none of the original soil surface remains undisturbed. Indeed, many soils and landscapes that have undergone bombturbation are so pedogenically and topographically altered, largely because of the long-lasting craters left behind, that the soils within the craters may have shifted onto a new pedogenic pathway-something that many other forms of pedoturbation often cannot accomplish. We use examples, mainly from the World War I battle of Verdun (France), to illustrate crater and rim morphology and postbombturbation soil development and to highlight the importance of this newly defined pedoturbation process.

Clinicoepidemiological and histopathological study of cutaneous amyloidosis with histopathological correlation

Background: Primary localized cutaneous amyloidosis is a commonly encountered problem in our scenario. As there is paucity of Indian studies on this subject, a clinico-epidemiological study was carried out. Objectives of the study were t o make an insight into the common clinical variants of primary localized cutaneous amyloidosis, to compare the age and sex distribution of various forms of PLCA, to study the etiological factors involved in primary localized cutaneous amyloidosis and to study the incidence, association, distribution, and histological correlation of PLCA. Methods: Patients having features of primary localized cutaneous amyloidosis attending the outpatient Department of Dermatology, Image Hospitals Hyderabad, India from June 2009 to 2010 was be enrolled into the study. Collection of data by history taking, clinical examination and skin biopsy was done in selected cases. Results: Positive family history was noted in a considerable number of patients. Pigmented macules with rippled pattern in macular amyloidosis and pigmented hyperkeratotic papules in lichen amyloidosis are the most common presentations and a combination of macular and lichen amyloidosis is seen in biphasic amyloidosis. Site most commonly involved in macular amyloidosis is extensor aspect of arm and anterior aspect of lower leg in lichen amyloidosis. Conclusions: Nodular cutaneous amyloidosis and sometimes lichen amyloidosis are associated with systemic amyloidosis. So such patents likely to develop systemic amyloidosis should be screen internally to rule out systemic amyloidosis.
New Labour? The Effects of Migration from Central and Eastern Europe on Unemployment and Wages in the UK

Abstract The UK was one of only three countries that granted free movement of workers to accession nationals following the enlargement of the European Union in May 2004. The resulting migration inflow, which was substantially larger and faster than anticipated, arguably corresponds more closely to an exogenous supply shock than most migration shocks studied in the literature. We evaluate the impact of this migration inflow – one of the largest in British history – on the UK labour market. We use new monthly micro-level data and an empirical approach that investigates which of several particular labour markets in the UK – with varying degrees of natives’ mobility and migrants’ self-selection – may have been affected. We found little evidence that the inflow of accession migrants contributed to a fall in wages or a rise in claimant unemployment in the UK between 2004 and 2006.
Effect of excessive internet use in Saudi and Egyptian teenagers’ health: Comparative study

Using of the internet today is a growing part of any society. Teenagers are the most users of the internet at their home and/or school. Therefore, it changes their daily lives in terms of physical, social, and psychological status that may exaggerated to be an internet addiction disorder or a physical problem. The aim of the study was to recognize the effects of excessive internet use in Saudi and Egyptian teenagers’ health. The design used to conduct the present study was a descriptive correlation design, a convenient sample of 668 teenagers who were recruited from intermediate and secondary school from both countries, 331 teenagers from King Saudi Arabia (KSA) and 337 from Arab Republic of Egypt (ARE). Three tools were used for data collection: the first one was a questionnaire including demographic background of the participants and their families. The second was Internet Addiction Test (IAT) Young (1998) and the third pain rating scale to assess the intensity of musculoskeletal pain that encountered by the students. Results show that 86.6% of KSA teenagers used the internet daily compared to 69.6% in ARE. Regarding internet addiction, in teenagers, 0.9% were severe, 45.3% moderate and 47.7% mild compared to 0.3%, 46.3% and 44.2% in ARE one, 67.3% of KSA teenagers have musculoskeletal pain with internet usage compared to 74.3% in ARE teenagers. No significant relation was found between both groups in relation to internet addiction. A significant relations were found in Saudi students’ socio-demographic data and their level of internet addiction in the area of academic level ( p ≤ .001), and level of academic achievement ( p = .037). No significant relation was found in the same area for Egyptian students. The researchers suggest further studies to be conducted in this field on larger sample size for both genders to identify the other factors related to excessive internet use.
Healthy Lifestyle Behaviors and Self-Efficacy: The Effect of Education

Abstract The aim of study is to examine the effects of education based Social-Cognitive Theory (SCT) and Health Promotion Model (HPM) on health behaviors and self-efficacy levels in women with Gestational Diabetes Mellitus (GDM). The study was a quasi-experimental design and was conducted in the obstetrics service of a university hospital with sixty pregnant women as the sample population. The data was collected using the Health Promotion Lifestyle Profile II (HPLP II) Scale and Self-Efficacy Scale (SES) between 1st February and 15th October 2010. Chi-square and independent samples t-test were used for the data analysis. It was observed that there was a significant increase in the average scores of the HPLP II Scale for the intervention group between follow-ups. However, it was also noted that there was no significant difference in the average scores of the SES for groups between follow-ups. The results showed that education had a positive effect in terms of adopting healthy lifestyle behaviors by women with GDM.
Collaboration in Healthcare Through Boundary Work and Boundary Objects

This article contributes to our understanding of how boundary work is practiced in healthcare settings. Previous studies have shown how boundaries are constantly changing, multiple, and co-existing, and can also be relatively stable cognitive and social distinctions between individuals and groups. In highly specialized, knowledge-intensive organizations such as healthcare organizations, organizational, professional, and disciplinary boundaries mark the formal structure and division of work. Collaboration and coordination across these boundaries are essential to minimizing gaps in patient care, but also may be challenging to achieve in practice. By drawing on data from an ethnographic study of two hospital wards, this article investigates practices of cross-disciplinary and professional collaboration and adds to our knowledge of how this kind of boundary work is produced in context. Moreover, it adds to existing boundary literature by exploring the fast-paced, situational, micro-interactions in which boundaries are drawn, maintained, and dissolved. These mundane, brief exchanges are essential to the practice of collaboration through boundary work. I consider the implications of these findings for boundary theory and boundaries in healthcare and other related settings.
The study of ultrasonic pulse velocity on plain and reinforced damaged concrete

An ultrasonic pulse velocity (UPV) test is often applied to determine the quality of concrete structures. It is well known that there are several factors which can influence the reading of ultrasonic velocity in concrete. One of the factors is the presence of steel reinforcement. Therefore, this paper is intended to evaluate the ultrasonic pulse velocity propagation either in plain or reinforced damaged concrete. A study on sound concrete is also provided as a comparison. Three mixes of concrete were provided, with 25 MPa, 35 MPa, and 45 MPa target compressive strengths. The specimens were 200x200x200 mm cube concrete specimens and 100x150x1100 mm reinforced concrete beam specimens. Each specimen was examined for velocity readings in sound and damaged concrete (25% and 50% of maximum load). In all concrete grades of both plain and reinforced concrete, the ultrasonic velocity decreases as the damage level increases. During intact conditions, the velocity of reinforced concrete is around 4.5% higher than that of plain concrete. However, damaged reinforced concrete has a lower velocity than plain damaged concrete. Furthermore, a new equation for predicting ultrasonic pulse velocity in reinforced concrete is proposed.
Allozyme variations in leaf esterase and root peroxidase isozymes and linkage with dwarfing genes in induced dwarf mutants of grass pea (Lathyrus sativus L.)

Genetic basis of different leaf esterase and root peroxidase isozymes was investigated by analyzing their zymogram phenotypes in selfed and intercrossed progenies of two local varieties (used as control) and three induced true breeding dwarf mutant lines of grass pea (Lathyrus sativus L.). Two non-allelic genes, df1/df2 and df3 controlling dwarfism in grass pea were included in the present linkage studies with different isozyme loci. The dwarf mutants could be distinguished from one another and also from control varieties by the presence of unique allozyme/s coded by allele/s in different loci. A good fit to 1: 2: 1 in F2 and 1:1 in back cross indicated monogenic segregation of isozyme loci with co-dominant expression of different alleles and the isozymes were functionally monomeric. Linkage analysis revealed closely linked associations among Est-1, Est-2and df3 loci and also between Est-3 and Prx-1 loci. All five genes, however, assorted independently with df1/df2 as well as with prx-3. Locus prx-2 was monomorphic in all five parents. Key words: Dwarf mutants, isozymes, linkage, Lathyrus sativus L.
Tunable structures and properties of electrospun regenerated silk fibroin mats annealed in water vapor at different times and temperatures

Regenerated silk fibroin (SF) mats were fabricated using electrospinning technique, followed by mild water vapor annealing to effectively tune the structures and improve the mechanical properties of the mats at different annealing times and temperatures. The breaking strength and the breaking energy of the mats treated with water vapor at 65°C for 12 h reached 6.0MPa and 171.7 J/kg, respectively. The conformational transition of the SF mats was significantly influenced by the treating temperature, while the influence of time was comparatively limited. The influence is consistent with the time-temperature equivalent principle and would be helpful for the preparation of water-vapor-annealed silk-based biomaterials for various applications.
A comprehensive model of customer trust in two retail stores

Purpose – The purpose of this paper is to develop and test a comprehensive model of customer trust in a retail service setting. Three levels of the customer‐to‐store relationship are simultaneously taken into account: customer to sales associates, customer to store branded products, and customer to the store itself.Design/methodology/approach – Using partial least square (PLS) on a sample of 393 customers of an Italian supermarket retailer, a model linking customer trust (in the store, in store branded products and in sales associates) to overall perceived value and store loyalty intentions and behaviors is tested. Subsequently an expanded model to determine the influence of managerially controlled antecedent variables (salespeople's trustworthiness, store environment, store assortment, and communications) is estimated on the various trust levels.Findings – Trust in the salesperson and trust in store branded products have positive effects on overall store trust. Store trust, in turn, increases perceived v.
Economic benefits of public investment in weed management: the case of vulpia in south‐eastern Australia's temperate pasture areas

The present paper reports an economic evaluation of the long-term benefits to Australia of research by the Cooperative Research Centre for Weed Management Systems (CRC) into the improved management of vulpia, the major annual grass weed of temperate pastures in New South Wales and Victoria. Vulpia reduces livestock production by competition with more desirable pasture species, by the production of low quality feed at critical times of the grazing cycle, and by injury to animals. A 20-year stochastic benefit-cost analysis indicated that reducing the impacts of vulpia in these pastures produced a mean net present value of $A58.3 million and a mean benefit-cost ratio of 33:1. Temperate pasture zone wool producers would capture the largest shares of these benefits, Australian consumers would gain, but wool producers in the rest of Australia would suffer welfare losses from vulpia reductions in the temperate pasture zones.

To cheat or not to cheat? A trial of the JISC Plagiarism Detection Service with biological sciences students

In the UK, there is great concern about the perceived increase in plagiarized work being submitted by students in higher educations. Although there is much debate, the reasons for the perceived change are not completely clear. Here we present the results of a 2‐year trial of the JISC Plagiarism Detection Service (PDS) involving hundreds of students. The effectiveness of the service in detecting plagiarized material and in acting as a deterrent are discussed. Although an increased number of cases of plagiarism were detected during the trial, the relative contributions of the electronic detection system and increased staff awareness remain unknown.
Genus Brachyspira in Birds : Phenotypes , Phylogeny and Pathogenicity

Spirochaetes of genus Brachyspira colonize the large intestine of some mammals and birds, and cause intestinal disease and production losses in pigs and chickens. The precise significance of Brachyspira spp. colonization in birds, the bacterial species involved, and the epidemiology are incompletely understood. Possible transmission between birds and mammals, and the role of wildlife have previously received little attention. In this thesis intestinal spirochaetes were isolated from commercial laying hens and free-living wild mallards (Anas platyrhynchos), jackdaws (Corvus monedula), rooks (C. frugilegus) and hooded crows (C. corone cornix). The isolates were investigated by phenotypic tests, molecular methods (PCR, RAPD, PFGE, sequencing of 16S rRNA and nox genes) and phylogenetic analysis. Experimental animal models were applied in pigs and mallards to study colonization rates and enteropathogenicity. The results showed that Brachyspira spp. were commonly isolated from the investigated species. Phenotypic and molecular analyses showed considerable diversity, and simultaneous colonization by two or more species or genetic variants of the same species was commonly found. In laying hens, pathogenic species (B. intermedia and B. alvinipulli), presumed non-pathogenic species (B. innocens, murdochii, ‘B. pulli’), and isolates that could not be assigned to any presently known species were isolated. No association with disease or production losses was identified. The etiologic agent of swine dysentery, B. hyodysenteriae, was isolated from mallards, which is the first time from wild birds. A putative novel species, ‘B. suanatina’, was isolated from mallards and Swedish and Danish pig herds. Isolates from both a pig and a mallard were shown to cause diarrhoea in pigs by experimental challenge. In mallards, focal epithelial changes were observed with B. hyodysenteriae and ‘B. suanatina’. Another novel and presumed non-pathogenic species, ‘B. corvi’, from corvid birds, was characterized and provisionally described. The results of the thesis highlight the diagnostic difficulties, the genetic diversity, and suggest that birds may be important reservoirs of Brachyspira spp.
Pilot study: Designing Medical Alarm Sounds For Semantic Association And Ease Of Learning

The performance of a new set of alarm sounds, generated from recordings of words descriptive of the situation relevant to the alarm and based on the principle of phonic abbreviation, were tested. Twenty-one volunteers aged from 24 to 54 were recruited for the study. Before being trained to recognise the sounds, they correctly identified 16.57% (range 0.00% to 76.19%) of the descriptive words used. The mean correct identification rates for the sounds after training was 56.35% (range 17.78% to 93.02%). Limited urgency mapping testing showed that the intrinsic urgencies of the low, medium and high priority forms of the sounds were statistically significantly separate (p<0.01). These results suggest that it may well be possible to construct a set of alarm sounds, for use on physiological monitoring instruments, using the concept of phonic abbreviation, which may have superior learnability to other systems without being unacceptably easy for casual hearers to understand.
