Abstract:

ABSTRACT The location of a galaxy cluster’s centroid is typically derived from observations of the galactic and/or gas component of the cluster, but these typically deviate from the true centre. This can produce bias when observations are combined to study average cluster properties. Using data from the BAryons and HAloes of MAssive Systems (BAHAMAS) cosmological hydrodynamic simulations, we study this bias in both two and three dimensions for 2000 clusters over the 1013–1015 M⊙ mass range. We quantify and model the offset distributions between observationally motivated centres and the ‘true’ centre of the cluster, which is taken to be the most gravitationally bound particle measured in the simulation. We fit the cumulative distribution function of offsets with an exponential distribution and a Gamma distribution fit well with most of the centroid definitions. The galaxy-based centres can be seen to be divided into a mis-centred group and a well-centred group, with the well-centred group making up about $60{{\ \rm per\ cent}}$ of all the clusters. Gas-based centres are overall less scattered than galaxy-based centres. We also find a cluster-mass dependence of the offset distribution of gas-based centres, with generally larger offsets for smaller mass clusters. We then measure cluster density profiles centred at each choice of the centres and fit them with empirical models. Stacked, mis-centred density profiles fit to the Navarro–Frenk–White dark matter profile and Komatsu–Seljak gas profile show that recovered shape and size parameters can significantly deviate from the true values. For the galaxy-based centres, this can lead to cluster masses being underestimated by up to $10{{\ \rm per\ cent}}$.

Abstract:

An investigation of distribution and species frequency of the nine genera of the subtribe Leipoldtiinae shows that two centres of diversity can be distinguished. These coincide more or less with the 'Gariep centre’ in the north and the ’Vanrhynsdorp centre' in the south (both sensu Nordenstam 1969). Speciation seems to have occurred in both centres. The subtribe may have evolved in an arid winter rainfall area which could have been situated outside its present distribution area. The centres of distribution coincide with those observed in both subfamilies of the Mesembryanthemaceae.

Abstract:

This research paper investigates the spatial distribution of urban centres in Tafila Governorate, by determining their spatial extension, their actual centre of gravity, the expected and the median centre. To analyse this pattern spatial statistical methods were used and the technical capabilities represented by the technology of geographic information systems. The results of the study showed the average locations for the distribution of urban centres, the location of the spatial mean, the weighted spatial mean according to the population, and the location of the spatial mediator and the weighted spatial mediator. A convergence between these sites was found clearly evident. In addition, the weighted standard distance for the spread of urban centres was calculated, and the direction of the spatial distribution of the urban centres was determined to show the extent of dispersion of those centres around the weighted spatial mean. The study also showed that the distribution pattern of urban centres in the governorate takes the spatial scattered pattern by applying the closest neighbour analysis; the analysis showed the population weight in the form of points and in the form of rings reflecting the population density of the communities in each of the areas selected for study. In addition, by using Thiessen polygons, the drawing of urban centres’ areas (regions) was revealed. The study recommended the necessity of classifying urban centres, developing special planning standards compatible with the local reality, and creating a comprehensive database in collaboration with the authorities responsible with the planning process of urban centres.

Abstract:

The capital and technology transfer into a certain region leads also to increased demands for logistic services. The transition to the logistic delivery organisation is very important under the conditions of accelerated technological development, in particular in the field of telecommunications and informatics, which enabled the advent of successful companies having a single employee. Owing to the mentioned technologies these companies get networked with similar companies, thus being able to solve all their needs by outsourcing the services or products of other networked companies. Higher speed and greater flexibility of operation of such companies has brought the following challenge: larger number of small companies has created a larger number of small orders that have to be delivered within the same unit of time. The logistics and distribution centres can represent a solution which maintains the speed and efficiency, and avoids costs of congestions and delays. KEY WORDS: capital transfer, technology transfer, logistics and distribution centres, optimisation

Abstract:

Abstract The centre determination of a galaxy cluster from an optical cluster finding algorithm can be offset from theoretical prescriptions or N-body definitions of its host halo centre. These offsets impact the recovered cluster statistics, affecting both richness measurements and the weak lensing shear profile around the clusters. This paper models the centring performance of the redMaPPer cluster finding algorithm using archival X-ray observations of redMaPPer-selected clusters. Assuming the X-ray emission peaks as the fiducial halo centres, and through analysing their offsets to the redMaPPer centres, we find that ${\sim } 75\pm 8 {{\ \rm per\ cent}}$ of the redMaPPer clusters are well centred and the mis-centred offset follows a Gamma distribution in normalized, projected distance. These mis-centring offsets cause a systematic underestimation of cluster richness relative to the well-centred clusters, for which we propose a descriptive model. Our results enable the DES Y1 cluster cosmology analysis by characterizing the necessary corrections to both the weak lensing and richness abundance functions of the DES Y1 redMaPPer cluster catalogue.

Abstract:

Logistics and distribution centres represent very significant infrastructure elements of the macro-logistic system. The creation of the logistics and distribution centres and their connection into a wide (global) network have resulted in the creation of conditions for an adequate distribution of labour and significant increase in the productivity of all the logistics elements and processes, noting that the logistics and distribution centres in this concept have a superregional significance. This paper represents the summary (results) of the research that was carried out on a large number of logistics and distribution centres with the aim of considering the complexity and the issues related to the logistics and distribution centres and the distribution network, their elements and action of the subsystems according to the following criteria: spatial, technical, technological, and organizational, with the aim of defining the categorisation model of the logistics and distribution centres. The analysis of the selected data collected during the research has resulted in defining of the categorisation model of the logistics and distribution centres which foresees six categories. Each of the foreseen categories has been defined according to the set model by the mentioned traffic, technical and technological, and organisational characteristics and the level of service. This is precisely where the application of the categorisation model of the logistics and distribution centres can be found, which will define the relevant categories of the centres applicable in the creation of effective distribution

Abstract:

In this paper the changing behaviour of three shopping centres over time is described. The middle-ranked centre had stable occupancy levels, and shopping patronage over a finite time period is shown from the Fourier analysis to be periodic. The largest shopping centre does not exhibit the same behavioural characteristics. It is argued that agglomerative effects distort the space — time associations in the patronage distributions there. There is a return to the classical view of space-discounting shopping opportunities in the differential equation, and the results reflect the spatial trends observed in the survey data. When boundary conditions are applied to this equation, particularly for smaller shopping centres, a number of interesting conclusions can be drawn. Of particular significance is that consumers within the centres are viewed as jump discontinuities in the patronage distribution and that the gravity relationship changes depending on the time of survey.

Abstract:

In recent years the providers of logistic services are under big pressure to lower their expenses and improve their quality. One way of accomplishing this task is the centralization of logistic activities. The paper presents possible methods for restructuring the distribution network on the case of Slovak Post p.l.c. By reducing the number of centres for distribution and by creating larger centres one can expect improvement in the process efficiency. There is no simple method to find the optimal distribution network. One possible way to tackle this problem is to use aggregation methods to group customers on the micro and macro levels. Several aggregation methods, including two new ones are presented and compared for the centres’ and delivery districts. New measurements for the quality of aggregation are created and tested on real data using all the discussed aggregation methods.

Abstract:

A series of offshore intra-basinal igneous centres have been documented across the North Atlantic Igneous Province including the UK, Ireland and Greenland. However, inconsistent cross-border terminology implies that similar features are not present in the Norwegian offshore, which, in turns, leads to misperceptions of cross-border geological differences. This paper presents evidence for a series of Norwegian igneous centres and suggests a consistent non-genetic cross-border terminology. In the Møre Basin, several igneous centres sit close to the continent–ocean boundary (COB), which have previously been identified as seamounts and/or ‘outer highs’. To provide cross-border consistency these features are consolidated under umbrella terms: igneous centres or volcanic fissures. Further centres are probably present within the Møre Basin (east of the COB) where 3D seismic data were not available. In the Vøring Basin two new igneous centres, one intrusive and one extrusive, are identified within the continental domain. Additionally, a possible deep magmatic upwelling associated with the regionally significant T-Reflector is identified. These igneous centre end-members represent the complexity of the magmatic plumbing across the Norwegian margin. With further data it is likely that further igneous centres will be identified offshore mid-Norway.

Abstract:

The importance of disaster logistics and its share in the logistics sector are increasing significantly. Most disasters are difficult to predict; therefore, a set of measures seems to be necessary to reduce the risks. Thus, disaster logistics needs to be designed with the pre-disaster and post-disaster measures. These disasters are experienced intensely in Turkey and the importance of these measures becomes more evidential. Therefore, accurate models are required to develop an effective disaster preparedness system. One of the most important decisions to increase the preparedness is to locate the centres for handling material inventory. In this context, this paper analyses the response phase designing the disaster distribution centres in Turkey at the provincial level. AHP (Analytical Hierarchy Process) based TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) method and goal programming model integration is used to decide alternative locations of distribution centres. TOPSIS method is employed for ranking the locations, which is based on hazard scores, total area, population, and distance to centre. Two conflicting objectives are first proposed in the goal programming formulation, in which maximization of the TOPSIS scores and minimization of the number of distribution centres covering all demands named set covering model are included. Although Gecimli has the highest priority with 0.8 p score in the TOPSIS ranking, Altincevre (0.77) and Buzlupınar (0.75) ensure both the TOPSIS score and coverage of the demand nodes. The results from this paper confirm that the computational results ensure disaster prevention insights especially in regions with limited data.

Full text

Abstract:

The authors contribute to the developing literature on call centres by providing detailed empirical evidence on the spatial unevenness in the distribution of call centre activity. They argue that the driving forces of call centre growth, whether as the rationalisation of back-office functions or as entirely new entities, have been corporate strategy and the pursuit of low-cost competitive advantage. Thus, although technological developments at the heart of call centre operations render them relatively ‘footloose’ in locational terms, the search for specific characteristics makes certain regions (and parts of regions) more attractive than others. By using a sample database of call centres, the authors describe the characteristics of call centres in the United Kingdom in terms of size, sector, and spatial distribution. They then attempt to explain the determinants of call centre location at the county level through a multiple regression analysis. The results indicate that there is a propensity to site call centres close to existing concentrations of allied activity, with preferences for densely populated areas mediated by needs to maintain employee access and avoid staff turnover problems. This has important implications for the spatial division of labour, with call centre growth likely to reinforce existing spatial unevenness in employment in key service activities. The authors conclude by considering the implications of these findings for contemporary urban and regional development, as well as providing a number of suggestions for future research.

Abstract:

Model powder diffraction patterns were calculatedviathe Debye formula from atom positions of a range of energy-relaxed closed-shell cubooctahedral clusters. The energy relaxation employed the Sutton–Chen potential scheme with parameters for palladium. The assumed cluster size distribution followed lognormal distribution of a crystallite volume centred with the diameter of 5 nm, as well as two bimodal lognormal distributions centred around 4 nm and 7 nm. These models allowed an in-depth analysis of the Warren–Averbach method of separating strain and size effects in a peak shape Fourier analysis. The atom-displacement distribution in the relaxed clusters could be directly computed, as well as the strain Fourier coefficients. The results showed that in the case of the unimodal size distribution, the method can still be successfully used for obtaining the column length distribution. However, the strain Fourier coefficients obtained from three reflections (002, 004 and 008) cannot be reliably estimated with the Warren–Averbach method. The primary cause is a non-Gaussian strain distribution and a shift of the diffraction maximum, inherent to the nanoparticles, differing for every constituent cluster in the size distribution. For the bimodal size distributions, the obtained column length distributions tend to be shifted towards the centres of the modes and are less sensitive to the larger size mode.

Abstract:

A survey has been made of the position of molecular centres in unit cells for the seven most populated space groups in the Cambridge Structural Database. Visual inspection of histograms and scattergrams reveals very clear peaks and clusters, showing preferred locations for molecules. These preferred positions are midway between centres of symmetry or screw axes. Some simple calculations of interaction energies of molecules with neighbours in a molecular coordination sphere suggest reasons for these preferred positions. These diagrams show that simplification of molecules to spheres is helpful in visualizing the prevalence of layers of molecules and tendencies to the ideal close packing of spheres. global minimum, but not always. This observation has been noted both by workers who have exhaustively explored packing parameter space (Williams, 1969; van Eijck, Mooij & Kroon, 1995) or have used Monte Carlo methods plus simulated annealing to take statistical samples of the total space and proceed to a local minimum (Karfunkel & Gdanitz, 1992). What is certain is the importance of the principle of close packing. The present study takes the approach of looking at the total available data on packing of molecular crystals to identify certain tendencies in packing and certain commonly occurring patterns. If such patterns exist then these will have implications as regards the methods of prediction, if only on the basis of probability of occurrence.

Abstract:

AbstractCrop wild relatives (CWR) are important sources of adaptive diversity for plant breeding programmes. This paper aims to investigate the extent to which the centres of crop origin/diversity are congruent with areas of high CWR diversity. We established the predicted potential CWR distributions for 1,425 CWR species related to 167 crops using 334,527 known distribution locations and generated a global CWR hotspot map. This was then compared to the centres of origin/diversity proposed by Vavilov (amended by Hawkes); Zeven and Zhukovsky’s mega gene centres, Harlan’s centres and non-centres of crop domestication; and crop domestication areas identified using current archaeological evidence proposed by Purugganan and Fuller. Greatest congruence between the global CWR hotspots and other concepts was found with the concept proposed by Vavilov and amended by Hawkes, but there remained significant differences between the CWR hotspots and Vavilov’s concept. This paper concludes that all four centre concepts reviewed have some overlap with CWR diversity but that Vavilov’s original concept has the closest geographic coincidence with CWR hotspots. With the benefit of significant additional global datasets to those used by Vavilov, we were able to suggest amendments to his concept, adding further centres based on CWR hotspots in west and east USA, West Africa, South-east Brazil and Australia. As a result of this study more precise targeting of CWR and crop landrace can be implemented in future, aiding global food and nutritional security.

Spirogyra nucleoli were shown by three-dimensional optical microscopy of DAPI fluorescence to contain DNA with a pattern and distribution matching those of the fibrillar centres. This was confirmed using different species with nucleoli showing different sizes of fibrillar centre. Much lower levels of fluorescence were seen corresponding to the dense fibrillar component. Nearly all the DAPI fluorescence arises from the fibrillar centres or from regions very close to their surface, indicating that this is the site of nucleolar transcription.

City and their surroundings are functionally interdependent and it grows through interaction with the periphery. If an urban centre develops, it diffuses its development in surrounding rural areas which can help to develop the whole region. For this reason, it is necessary to find out the growth centres their functional relations with the adjoining area. This paper is an attempt to identify the functional importance of the urban centres their hierarchical distribution and also to delineate the sphere of influence of urban centres of Darjeeling and Jalpaiguri district of West Bengal. Various statistical techniques are to be incorporated for this purpose. The result indicates that higher the functional importance greater the zone of influence and vice-versa.

Abstract:

AbstractWe have investigated a diamond crystal that consists of several misorientated subgrains. The main feature of the crystal is the dark areas in the cathodoluminescent core that has ‘estuary-like’ boundaries extending along the subgrain interfaces. The core has >3100 ppm of nitrogen, and the share of the B form is >95%; the absorbance of the centre N3VH at 3107 cm–1 reaches 75 cm–1. The N3 centre absorbance, as well as N3 luminescence, is absent in the core. In the outer part of the crystal, bright blue luminescence of the N3 centre is apparent, and the N3 absorbance reaches 5.3 cm–1. These observations could be explained by the conversion of N3 centres to N3VH after attaching a hydrogen atom. After the full conversion of the N3 centres, the diamond becomes darker under CL. We hypothesise the dark core has a specific shape due to the post-growth diffusion of the hydrogen.

Abstract:

The purpose of this study is to analyse the disparities in the distribution of percutaneous coronary intervention (PCI) centres in Poland and the impact of eventual inequities on access to the invasive treatment of acute myocardial infarctions (AMI). To examine the distribution of PCI centres against population size and geographic size in Poland, the Gini coefficient calculated based on the Lorenz Curve was engaged. In addition, the regression function was employed to estimate the impact of distribution of PCI centres on access to invasive procedures (coronarographies and primary percutaneous coronary intervention). Data were collected from the public statistical system and Polish National Health Fund database for the year 2018. The relation and the level of equity was measured based on the aggregated data at a district (voivodeship) level. The results of the Gini coefficient analysis show that the distribution of invasive cardiology units measured against population size is more equitable than when measured against geographic size. In addition, the regression analysis shows the moderate size of the positive correlation between number of PCI centres per 100,000 population and the number of all categories of the invasive treatment of AMI per 100,000 population, and the lack of similar correlation in case of the number of PCI centres expressed per 1000 km2, which could be evidence of an insufficiency of PCI centres in areas where the concentration of PCI centres per 100,000 population is lower. The main implication for policy makers that results from this research is the need for a correction of PCI centres distribution per 100,000 inhabitants to ensure better access to invasive procedures.

Abstract:

SynopsisIn SW Asia 260 species of Centaurea in 38 sections are recognised. Species numbers are highest in S and E Turkey and adjacent Iran and Iraq. East Iran and Afghanistan are poor in species. The number of sections is largest in NE Turkey (and adjacent Transcaucasia). Two hundred and one species are restricted to the area under study; the greatest number of narrow endemics is found in S and E Turkey. The subgenera and sections show quite different patterns of distribution and centres of diversity. The data presented point to E Anatolia and adjacent areas as the foremost centre of evolution for the genus and make probable a relatively recent speciation; an important secondary centre is S Turkey (and of course several other Mediterranean countries too). Some notes are added on the morphological variation in the genus and possible factors influencing its evolution.

Abstract:

The aim of this study is to identify and map the spatial distribution of species richness and endemism of the genus Acacia in Australia. A database of 171 758 geo-referenced herbarium records representing 1020 Acacia species was assembled and aggregated to a 0.25° grid cell resolution. A neighbourhood analysis of one-cell radius was applied to each of the grid cells to map the spatial patterns of species richness and endemism. The primary centres of species richness are in accordance with previous results, occurring in the South-West Botanical Province in Western Australia, the MacPherson-Macleay overlap and the Central Coast of the Sydney Sandstone region. We identify 21 centres of endemism, of which six were previously unrecognised. The primary centres of endemism are located in South-West Western Australia, the Kimberley District and the Wet Tropics in Queensland. The South-West Botanical Province in Western Australia contained the greatest number of regions with the highest number of endemic species of Acacia. A randomisation test showed that our 21 centres of endemism were significantly different from random. The majority of centres of Acacia endemism were incongruent with the centres of species richness, with only three grid cells in the top 1% for both measures. We also confirm that South-West Western Australia is a region of very high species richness and endemism, in accordance with its status as a global hotspot of biodiversity.

Abstract:

At the Tiré à part conference held in Quebec city in October 2003, speakers from artist-run centres from across Canada discussed 30 years of experience in publishing. Themes such as audience, production, funding, professionalisation and distribution encouraged the identification and exploration of current issues. These are put in context here by a general overview of the development of the genre as well as a short history of production by artist-run centres such as Art Metropole, Artspeak, Artexte and the Bookmobile project.

Abstract:

N.I. Vavilov hypothesized that the geographical centres of diversity of crops indicate their geographical centres of origin. Vavilov’s conclusions about the geographical origins of einkorn, durum and common wheat agree well with current population and molecular genetic studies when macro-geography is used but agree poorly when they are examined at higher resolution. We examined the causes of such disagreements for tetraploid emmer wheat and hexaploid common and club wheat. Molecular studies suggest that emmer was domesticated in the Diyarbakir region in south-eastern Turkey. Nucleotide diversity of wild emmer in the Diyarbakir region estimated earlier was compared with nucleotide diversity of wild and domesticated emmer across their distribution estimated here. Although domesticated emmer is only half as diverse as wild emmer, it is more diverse than the ancestral wild emmer population in the Diyarbakir region. Its centre of diversity is in the Mediterranean and does not coincide with the geographical centre of emmer origin. A similar disagreement exists in hexaploid wheat. Its centre of molecular diversity is in Turkey, which is west of the putative site of its origin in Transcaucasia and north-western Iran. It is shown that the primary cause of the disagreements between geographical centres of crop diversity and geographical centres of crop origin is gene flow from an ancestor subsequently to crop origin, which modifies the geographical pattern of crop diversity. When such gene flow takes place and when crop is domesticated in a peripheral population of the ancestor, the centre of crop diversity and the centre of crop origin are unlikely to coincide.

Abstract:

While the suburbanisation process has been well documented in some large cities of several developed countries, much less attention has been devoted to the case of small and middle-sized cities in developing countries. This article focuses on an exploratory spatial data analysis to investigate the location of the central business district (CBD) and other employment centres in Hermosillo, Mexico. The results reveal the significant presence of spatial dependence and spatial heterogeneity, although their extent varies with the sector under study. These spatial effects take the form of a persistent cluster of high values of employment around the historical district of the city shaping a huge CBD, although a sub-centre of high values emerges to the south and to the north-west of the CBD in 2004. Overall, Hermosillo is still characterised by a traditional monocentric model, but the role of its CBD has changed.
