Abstract Nearly 40 different Asian elm (Ulmus spp.) biotypes, growing at The Morton Arboretum, Lisle, IL, were evaluated in laboratory bioassays and in the field for suitability and feeding preference of the spring cankerworm Paleacrita vernata (Peck) and the fall cankerworm, Alsophila pometaria (Harris). No-choice and multiple-choice laboratory feeding studies, and field defoliation surveys revealed that U. castaneifolia, U. changii, U. chenmoui, U. davidiana, U. elongata, U. gaussenii, U. glaucescens var. lasiophylla, U. japonica, U. lamellosa, U. lanceaefolia, U. macrocarpa, U. parvifolia, U. propinqua, U. propinqua var. suberosa, U. prunifolia, U. pseudopropinqua, U. taihangshanensis, U. wallichiana, U. wilsoniana, U. wilsoniana-98, and the simple and complex hybrids U. davidiana x U. japonica, U. davidiana x U. propinqua, U. japonica x U. ‘Morton’-Accolade™, U. ‘Morton’-Accolade™ x U. japonicapumila, U. ‘Morton Glossy’-Triumph™, and U. ‘Morton Plainsman’-Vanguard™ x U. davidiana, were less suitable for larval development and pupation and less preferred by spring and fall cankerworm larvae. Ulmus americana, U. glaucescens, U. szechuanica, and the simple and complex hybrids U. davidiana x U. ‘Morton’-Accolade™, U. szechuanica x U. japonica, U. ‘Morton’-Accolade™, U. ‘Morton Red Tip’-Danada Charm™ and U. ‘Morton Plainsman’-Vanguard™ were more suitable for and more preferred by spring and fall cankerworm larvae. Rankings for larval development time were highly correlated with larval longevity, but the proportion of larvae pupating was correlated neither with larval longevity nor with larval development time. Pupal fresh weights also were correlated neither with larval longevity nor with larval development time. Mean fecal pellet weights were correlated with the proportion of larvae pupating, but were not correlated with pupal fresh weights. Ulmus chenmoui, U. glaucescens var. lasiophylla, U. lamellosa, U. macrocarpa, U. propinqua, U. prunifolia, and U. pseudopropinqua all showed medium to heavy leaf pubescence and were less suitable and less preferred by spring and fall cankerworms. Asian elms were least preferred by cankerworm larvae, followed in order of increasing preference by European and North American elms.

The aim is an assessment of the actual evapotranspiration of plants by using climate data in Nakhon Ratchasima with the R in the hydrological modeling function of Abtew and Morton CRAE formulation. There are using meteorological data from 2012 - 2016 at Nakhon Ratchasima station. The case analysis shows the results of evapotranspiration are the potential of evaporation of plants each year. Abtew analysis gave higher monthly evapotranspiration results during the dry season than Morton CRAE, but with Abtew formulation gave lower monthly evapotranspiration results during the rainy season than that of the method. The results are 2 ways to use evapotranspiration for water management, which is to analyze the amount of evapotranspiration for use in irrigation systems in order to water for plants should use the form of Abtew form because it can be seen that during the dry season and the plant has a high evapotranspiration value. Form Morton CRAE should be used to assess the potential water use of plants that can be seen in the dry season, the evaporation of plants is also less because in the surrounding environment there isn’t water and has little moisture causing plants to use less water.

Full textAbstract:
Vehicle ad hoc networks (VANETs) are special wireless networks which help vehicles to obtain continuous and stable communication. Pseudonym revocation, as a vital security mechanism, is able to protect legal vehicles in VANETs. However, existing pseudonym-revocation schemes suffer from the issues of low certificate revocation list (CRL) generation and update efficiency, along with high CRL storage and transmission costs. In order to solve the above issues, this paper proposes an improved Morton-filter-based pseudonym-revocation scheme for VANETs (IMF-PR). IMF-PR establishes a new distributed CRL management mechanism to maintain a low CRL distribution transmission delay. In addition, IMF-PR improves the Morton filter to optimize the CRL management mechanism so as to improve CRL generation and update efficiency and reduce the CRL storage overhead. Moreover, CRLs in IMF-PR store illegal vehicle information based on an improved Morton filter data structure to improve the compress ratio and the query efficiency. Performance analysis and simulation experiments showed that IMF-PR can effectively reduce storage by increasing the compression gain and reducing transmission delay. In addition, IMF-PR can also greatly improve the lookup and update throughput on CRLs.

AbstractThis paper demonstrates the application of a new higher-order weak approximation, called the Kusuoka approximation, with discrete random variables to non-commutative multi-factor models. Our experiments show that using the Heath–Jarrow–Morton model to price interest-rate derivatives can be practically feasible if the Kusuoka approximation is used along with the tree-based branching algorithm.

Full textAbstract:
Stephen C. Carlson's The Gospel Hoax sets out to validate the long-standing suspicion that Professor Morton Smith, late of Columbia University, forged his famous discovery of aletter of Clement of Alexandria, which quotes from a longer(“secret”)Gospel of Mark. This academic folklore has been passed on like an esoteric tradition since 1975, when Quentin Quesnell called on Smith to make the manuscript of this letter available for forensic testing in order to rule out the possibility of a recent hoax. Quesnell had difficulty substantiating his concerns. In his article in the Catholic Biblical Quarterly, he postulated that a modern scholar might have devised the letter as “a controlled experiment” in order to examine how scholars react to new evidence. Yet the manuscript of this letter, which Smith found in 1958, was inscribed on the last pages of a seventeenth-century book that purportedly was kept in a locked room of a monastery in the Judean desert. What modern forger would leave his creation there and gamble that someone would discover it in his lifetime? For this scenario to seem at all plausible, Quesnell needed to imply what he personally suspected, namely, that Smith forged it himself for this purpose. Accordingly, Quesnell described his hypothetical modern “mystifier” as someone who shared Smith's abilities, opportunities, resources, and interest in what people make of the document.

Full textAbstract:
The task of the author’s project “ecology without nature” is to use deconstruction to counteract prevailing normative ideas about nature for the sake of sentient beings suffering under catastrophic environmental conditions. Timothy Morton sees in the very idea of nature itself one of the obstacles to truly ecological politics, ethics, philosophy, and art. He calls for a thorough study of how nature is defined as a transcendental, unified and independent category. The study of how art represents the environment makes it possible to see that “nature” is an arbitrary rhetorical construct, devoid of a truly independent existence outside or beyond texts about nature. The rhetoric of nature itself depends on an ambient poetics, that is directed toward the evocation of the surrounding atmosphere or the world through text. Morton shows that people at different periods of time put various ideological meanings into the concept of “nature”; the historicization of this poetics makes obvious its vacuity of inner being and independent value. The history of ambient poetics depends on certain forms of identity and subjectivity, which are also historical. Without stopping at historicization, the author calls for the politicization of ecological art and the use of the rhetorical effect of “nature” as a slogan in order to strengthen environmentalism. The ecological thinking that Morton calls for does not operate with “nature” as a kind of ready-made, ideological concept and thus emerges as an ecology “without nature”. On the other hand, a non-conceptual image in environmental literature can be a convincing point of attraction for an intensive conceptual system — namely, an ideological one.

Full textAbstract:
Morton Feldman’s Last Pieces for piano solo of 1959 poses an interesting interpretive problem for the performer. As in many Feldman compositions of the 1950s and 60s, the first movement of the work is notated as a series of "sound events" to be played by the performer choosing the durations for each event. The only tempo indications are "Slow. Soft. Durations are free." This situation is complicated by Feldman’s remark about a similar work from 1960, "[I chose] intervals that seemed to erase or cancel out each sound as soon as we hear the next." I interpret this intension to keep the piece fresh and appealing from sound to sound. So, how the pianist supposed to play Last Pieces in order to supplement the composers desire for a sound to "cancel out" preceding sounds? To answer this question, I propose a way of assessing the salience of each sound event in the first movement of Last Pieces, using various means of associating each of its 43 sound events according chord spacing, register, center pitch and bandwidth, pitch intervals, pitch-classes, set-class, and figured bass. From this data, one has an idea about how to perform the work to minimize similarity relations between adjacent pairs of sound events so that they can have the cancelling effect the composer desired. As a secondary result of this analysis, many cohesive compositional relations come to light even if the work was composed "intuitively".

Full textAbstract:
In this article we provide a condensed review of literature on developmental dyslexia. Starting with the historical background to this language-based reading disorder, we discuss four key components that are crucial for a valid and operational definition of developmental dyslexia. We then present the major theoretical explanations of developmental dyslexia in order to gain a better understanding of the causes of this reading disorder. These causal explanations are addressed in the context of Morton and Frith’s (1995) model. Four major theories of developmental dyslexia are discussed: the phonological deficit theory, the double-deficit theory, the magnocellular theory, and the cerebellar theory. The last section of this review addresses the model of reading development proposed by Frith (1986). Understanding the developmental progression of children’s abilities in reading is crucial in order to detect in which phase of this progression a breakdown attributed to dyslexia occurs.

Full textAbstract:
Determining mobility status is an important component of any health assessment for older adults. In order for a mobility measure to be relevant and meaningful, normative data are required for comparison to a healthy reference population. The DEMMI is the first mobility instrument to measure mobility across the spectrum from bed bound to functional levels of independent mobility. In this cross-sectional observational study, normative data were obtained for the DEMMI from a population of 183 healthy, community-dwelling adults age 60+ who resided in Vancouver, Canada and Melbourne, Australia. Older age categories had significantly lower DEMMI mobility mean scores (P<0.05), as did individuals who walked with a mobility aid or lived in semi-independent living (assisted living or retirement village), whereas DEMMI scores did not differ by sex (P=0.49) or reported falls history (P=0.21). Normative data for the DEMMI mobility instrument provides vital reference scores to facilitate its use across the mobility spectrum in clinical, research, and policymaking settings.

Full textAbstract:
Against Nature, a book of L. Daston, is devoted to the historical transformations of the term “nature” and its significance in the formation of moral categories from Aristotle to our days. Daston pays special attention to the period between the seventeenth and eighteenth centuries when “modern science” emerged. Daston clarifies the essential contents of such terms as “nature”, “normativity”, and “universal natural laws”, reconstructs the contexts underlying the introduction of these categories into scholarly discourse and finds out their significance in a situation of the growing social importance of scientific knowledge. All these let Daston trace the logic of at least three ways for the “order of nature” to transfer into “moral order” and conclude that the order of nature only had a representative function. The review contains parts of the Russian translation of Daston’s main ideas and conclusions, its critical and historiographic evaluation. Daston’s thesis about the weakness of naturalisation as discoursive strategy is contemplated in the context of the criticism of anthropocentrism, vividly illustrated by works of M. Serres, B. Latour, D. Haraway and T. Morton.

Full textAbstract:
My essay will aim to prove that John McGahern’s Memoir foregrounds the material dimension of anticipatory grief and its aftermath as a space in which different affective responses to the “Thing” can be explored. Firstly, I look at how the text edits together memories of anticipatory grief in order to dramatize the “apparatus of thinking” (Steven Connor) as an affective spatiality (Marta Figlerowicz) in relation to an irrupting thingness within the object world. Secondly, I look at how McGahern and his father are “timed by things” (Timothy Morton) in their effort to remember or objectify affect, and how mourning itself becomes a matter of accepting nonhuman temporality. As such, this textual engagement with memories and inscriptions enacts a writerly form of anticipatory-vicarious grief, a “moral emotion” arising from the “anticipated harm” (Somogy Varga and Shaun Gallagher) that the subject feels will affect those close to her after her death.

We consider an arbitrage-free futures price model of Heath–Jarrow–Morton type which is driven by a multidimensional Wiener process and a marked point process. We find necessary and sufficient conditions for this model to produce a log futures curve that changes only through parallel shifts. The same analysis is carried out for the case when the log futures curve changes only through proportional shifts. We prove that there exist nontrivial parallel and proportional shifting log futures curves and we show how to specify the futures price model in order to obtain them. Additionally the shift functions are characterized. Finally, we consider the case of all other single-factor affine models which are neither parallel nor proportional shifting curves. We find necessary and sufficient conditions for the purely Wiener-driven log futures model to admit such other affine shifting curve and we characterize the shift functions.

Detailed calculations show that the two most important dynamical problems in the formulation of a theory of star formation (namely, the angular momentum and magnetic flux problems) can be resolved in that order by magnetic braking and ambipolar diffusion, respectively, relatively early during the collapse of an interstellar cloud or fragment. Although the physical processes involved are complicated and highly nonlinear and the formal solutions are mathematically nontrivial, they can often be elucidated by exact analogies with small-amplitude, transverse waves on strings, by a mechanical (or quantum mechanical) “leaky” system of N coupled oscillators, and by spinning coaxial metal disks joined by rubber bands and sharing (as well as losing to an external medium) energy and angular momentum (see Mouschovias and Morton 1985a, Astrophys.

Abstract For many years, archaeological research regarding the Oneota tradition has focused on broad similarities and trends among groups spread over a wide geographical area. While this research is important for understanding the tradition, examinations of synchronic variability between Oneota groups have been underdeveloped. Exploring this variability may help archaeologists better understand how different groups adapted to various social and environmental circumstances and the processes that led to the emergence of different historical social groups in the upper Midwest and eastern prairies. In order to begin exploring this variability in core practices, a pilot study was completed comparing cooking and foodways practices found during an analysis of vessel function on stylistically Oneota pots recovered at the Tremaine site (47Lc95) in Wisconsin and the Morton Village site (11F2) in Illinois. Preliminary results show that food practices between these two groups varied, possibly as a response to different social circumstances.

“Word, birch bark”: Does Piotr Janicki’s [Dog’s Book] Need an Ecocriticism (and Vce Versa)? The article presents the work of Piotr Janicki, one of the most interesting Polish poets of the middle generation (born 1974). The author focuses primarily on the 2018 untitled volume of poems, referred to as [A Dog’s Book], in order to recreate the structure of the subject it contains, using the categories offered by the ecocritical discourse, represented by the works of Anna Ubertowska, Rosi Braidotti, Timothy Morton and other. In the course of the analysis, it turns out that an important assumption of Janicki’s poetry is the desire to break the anthropocentric perspective, which would place his work in the trend of “deeply ecological” literature, the task of which is, inter alia, to “infect” readers with new forms of sensitivity and imagination, breaking with the traditionally understood humanism, which places man above non-human beings, and not in a network of relationships with them, as it happens in [The Dog’s Book].

Unbeknownst to most, in June of 1983, Quentin Quesnell made a visit to Jerusalem in order to personally inspect the Mar Saba document known as the Letter to Theodore. This is significant because it adds Quesnell to a small group of people who have testified to have seen the Letter to Theodore in person, and an even smaller group who have commented on its appearance and contents first-hand. Following Quesnell’s death in 2012 many of his personal belongings were acquired by Smith College (Northampton) and recently released to the public for viewing. Among Quesnell’s belongings was a journal full of notes, along with photos and letters to his wife Jean Higgins, all relating to Morton Smith’s discovery of the Letter to Theodore at Mar Saba and to Quesnell’s 1983 visit to Jerusalem. On the basis of these documents the following article offers a summary of Quesnell’s part in the debate over Smith’s discovery and a report of his inspection of the manuscript.

An experimental study of the structure of round buoyant turbulent plumes was carried out, limited to conditions within the fully developed (self-preserving) portion of the flow. Plume conditions were simulated using dense gas sources (carbon dioxide and sulfur hexafluoride) in a still air environment. Velocity statistics were measured using laser velocimetry in order to supplement earlier measurements of mixture fraction statistics using laser-induced iodine fluorescence. Similar to the earlier observations of mixture fraction statistics, self-preserving behavior was observed for velocity statistics over the present test range (87–151 source diameters and 12–43 Morton length scales from the source), which was farther from the source than most earlier measurements. Additionally, the new measurements indicated that self-preserving plumes are narrower, with larger mean streamwise velocities near the axis (when appropriately scaled) and with smaller entrainment rates, than previously thought. Velocity statistics reported include mean and fluctuating velocities, temporal power spectra, temporal and spatial integral scales, and Reynolds stresses.

I first encountered the name of Grohg some 25 years ago on the sleeve of Morton Gould's marvellous Chicago Symphony recording of Aaron Copland's Dance Symphony of 1929. Copland had hastily extracted this score from an unperformed ballet (written in Paris in 1922–5) in order to enter a major competition organized by RCA Victor records, when he realized that he would be unable to complete the planned Symphonic Ode in time for the deadline. I found this music very attractive indeed – amusingly Ballets Russes-ian to be sure but, in the precision and transparency of its sound-world, very characteristic of its author and not at all suggestive of a first attempt at orchestration (Grohg pre-dates the Organ Symphony, which was the first orchestral music of his own that Copland actually heard). I was also intrigued by the idea of a ballet that had been suggested by F. W. Murnau's classic silent horror film Nosferatu (1922).

Full textAbstract:
As laser scanning technology improves and costs are coming down, the amount of point cloud data being generated can be prohibitively difficult and expensive to process on a single machine. This data explosion is not only limited to point cloud data. Voluminous amounts of high-dimensionality and quickly accumulating data, collectively known as Big Data, such as those generated by social media, Internet of Things devices and commercial transactions, are becoming more prevalent as well. New computing paradigms and frameworks are being developed to efficiently handle the processing of Big Data, many of which utilize a compute cluster composed of several commodity grade machines to process chunks of data in parallel. <br><br> A central concept in many of these frameworks is data locality. By its nature, Big Data is large enough that the entire dataset would not fit on the memory and hard drives of a single node hence replicating the entire dataset to each worker node is impractical. The data must then be partitioned across worker nodes in a manner that minimises data transfer across the network. This is a challenge for point cloud data because there exist different ways to partition data and they may require data transfer. <br><br> We propose a partitioning based on <i>Z</i>-order which is a form of locality-sensitive hashing. The <i>Z</i>-order or Morton code is computed by dividing each dimension to form a grid then interleaving the binary representation of each dimension. For example, the <i>Z</i>-order code for the grid square with coordinates (<i>x</i> = 1 = 01<sub>2</sub>, <i>y</i> = 3 = 11<sub>2</sub>) is 1011<sub>2</sub> = 11. The number of points in each partition is controlled by the number of bits per dimension: the more bits, the fewer the points. The number of bits per dimension also controls the level of detail with more bits yielding finer partitioning. We present this partitioning method by implementing it on Apache Spark and investigating how different parameters affect the accuracy and running time of the <i>k</i> nearest neighbour algorithm for a hemispherical and a triangular wave point cloud.

Wireless sensor network technology has the potential to reveal fine-grained, dynamic changes in monitored variables of outdoor landscape. But there are significant problems to be overcome in order to realize the vision in working systems, such as effective utilize of energy, prolong network life and improve sensor accuracy. This paper describes the design and evaluation of a sensor network with an effective data aggression algorithm applied in orchard microclimate monitor. A novel feature of the solution is its data compression algorithm design, in which all sensors were encoded with Morton code and a logical multi-lays cluster was constructed among the nodes. Making use of the similarity of the output of the sensors, the algorithm reduces network data amount and power cost significantly to prolong life of the network. Tests and experiments results are shown in diagrammatic form. The system was field tested over one month in Nankou farm located in Beijing province of China. The experimental results demonstrate that effective collecting of environmental information can be achieved by using our proposed system.

The study reported here was concerned with the issue of reverse engineering of language test items as it relates to the identification of the language constructs underlying listening tasks of LELTS test. In this regard, the IELTS examination papers, from IELTS 1 to IELTS 10 were compiled as a corpus for the analysis. Tasks were analyzed using a taxonomic frame work adopted from Moore, Morton and price (2012), that was originally adapted from Weir and Urquhart (1998), with a focus on two dimensions of difference: level of engagement, referring to the level of text with which a listener required to engage in order to respond to a task (local vs. global); type of engagement referring to the way (or ways) listeners expected to engage with a text in order to process the material to respond to a task (literal vs. interpretative). Overall, the analysis found evidences of bottom up processing underlying most IELTS listening tasks. The majority of tasks were identified to have a ‘local-literal’ configuration on their orientation, demanding primarily a basic understanding of relatively small textual units of the material. The results of the study were used to suggest the practical implications for the four groups of the people involved in the IELTS educational contexts: participants; teachers; material preparation experts, and curriculum designers.

Full textAbstract:
AbstractGramsican approaches in International Relations (IR) have sought to outline the relationship between ideas and material forces in the construction of world order. Scholars working within this broad school have sought to emphasise that ideas are material forces, and must be considered as concrete historical structures (Cox, 1987) central to the establishment of particular historical and hegemonic blocs. This literature has primarily focused on the discursive construction of hegemony by international elites and the impact this has on political practices. While these insights are important in understanding the construction of world order, it is necessary to extend them to include the creation of actual physical structures – that is, it is vital to link the ideational aspects of hegemony with actual material processes. I will argue that a consideration of the role of technology provides an ideal vehicle for this process, building on the preliminary work of Bieler and Morton in this regard (2008). Technological structures are the product of particular cultural values and embed these cultural values within their very structure. Physical material factors thereby express ideational values constructed by specific social forces. Social practices are thus not only a function of the dominance of certain ideological formations, but also the product of the material environment itself and the manner in which the human metabolism with nature must function through these physical constructions.

Full textAbstract:
The epoch of the Anthropocene is on the verge of becoming scientifically acknowledged by the science of Geology. In what way does this concern Philosophy? In this paper, we evaluate how the new concept of the Anthropocene contrasts with the classical concept of Nature, aiming to identify the territory of both. In order to do this we take as our starting point the approach of Francis Bacon (1561-1626) which separates God and Nature. This later translated into the separation of Nature and Culture. The latter dualism is contested by Philippe Descola (b.1942) who defends the convergence of both. Bruno Latour (b.1947) and Timothy Morton (b.1968) consider the concept of nature as obsolete. Ulrich Beck (1944-2015), Erie C. Ellis and Mark Lynas (b.1973) claim that science will be able to cope with whatever changes the Anthropocene brings. We consider that all these claims, albeit apparently contrasting, are grounded in belief and as a counter-proposal we aim to bring to the table the concept of spirituality as essential to re-evaluate what Nature is today in the light of the Anthropocene.

Full textAbstract:
One of Scott Cameron’s most recent contributions to environmental hermeneutics (a field in which he was a founding scholar) was to defend the concept of nature against those who would argue that it should be abandoned in order to stave off the ecological destruction. Rather than jettison nature as an outdated and unhelpful construct, Cameron argued for its redemption based on Gadamer’s hermeneutical insights into language. In this article, I will look at Cameron’s arguments against Steven Vogel as well as particular points made against nature as a concept recently articulated by Slavoj Žižek and Timothy Morton. I will follow these arguments through, demonstrating that while the arguments can be accepted and are, indeed, accurate, the conclusion that the concept of nature be abandoned need not and should not be conceded. Finally, I will return to Cameron’s hermeneutic defense of a concept of nature and expand further on his insights and arguments. With Cameron, I conclude that the concept of nature can be redeemed. Extending Cameron’s line of reasoning, I argue that this aim is accomplished by refiguring the concept of nature with the insights offered by philosophical hermeneutics.

A syntaxonomical revision of plant communities with dominant <em>Pinus mugo</em> in the Western Carpathians is presented. The data set of 341 relevés was examined and analysed using the detrended correspondence analysis and the cluster analysis. Major gradients and clusters were interpreted using Ellenberg’s indicator values. The major gradient in species composition was associated with available nutrients and moisture. The authors suggest distinguishing the dwarf pine stands of the supramontanous and subalpine belts of the Western Carpathians referred to the alliance Pinion mugo Pawłowski in Pawłowski et al. 1928 of the order Junipero-Pinetalia mugo Boşcaiu 1971 and the class Roso pendulinae-Pinetea mugo Theurillat in Theurillat et al. 1995, into three separate associations: the Cetrario-Pinetum mugo Hadač 1956, the Homogyno alpinae-Pinetum mugo (Sillinger 1933) nom. nov., and the Adenostylo alliariae-Pinetum mugo (Sillinger 1933) Šoltésová 1974. The authors also elucidated the unauthorized name of the association Vaccinio myrtilli-Pinetum mugo Hadač 1956, which is a younger homonym of the valid name of the association Vaccinio myrtilli-Pinetum montanae Morton 1927 that characterises the acidophilous dwarf pine stands on calcareous bedrocks in the Alps.

As laser scanning technology improves and costs are coming down, the amount of point cloud data being generated can be prohibitively difficult and expensive to process on a single machine. This data explosion is not only limited to point cloud data. Voluminous amounts of high-dimensionality and quickly accumulating data, collectively known as Big Data, such as those generated by social media, Internet of Things devices and commercial transactions, are becoming more prevalent as well. New computing paradigms and frameworks are being developed to efficiently handle the processing of Big Data, many of which utilize a compute cluster composed of several commodity grade machines to process chunks of data in parallel. <br><br> A central concept in many of these frameworks is data locality. By its nature, Big Data is large enough that the entire dataset would not fit on the memory and hard drives of a single node hence replicating the entire dataset to each worker node is impractical. The data must then be partitioned across worker nodes in a manner that minimises data transfer across the network. This is a challenge for point cloud data because there exist different ways to partition data and they may require data transfer. <br><br> We propose a partitioning based on <i>Z</i>-order which is a form of locality-sensitive hashing. The <i>Z</i>-order or Morton code is computed by dividing each dimension to form a grid then interleaving the binary representation of each dimension. For example, the <i>Z</i>-order code for the grid square with coordinates (<i>x</i> = 1 = 01<sub>2</sub>, <i>y</i> = 3 = 11<sub>2</sub>) is 1011<sub>2</sub> = 11. The number of points in each partition is controlled by the number of bits per dimension: the more bits, the fewer the points. The number of bits per dimension also controls the level of detail with more bits yielding finer partitioning. We present this partitioning method by implementing it on Apache Spark and investigating how different parameters affect the accuracy and running time of the <i>k</i> nearest neighbour algorithm for a hemispherical and a triangular wave point cloud.

Three-dimensional computations, rather than three-dimensional axisymmetric computations, are necessary since non-axisymmetric unstable drop behaviour is studied. The computations are performed using the sharp-interface coupled level-set and volume-of-fluid (CLSVOF) method in order to capture the deforming drop boundary. In the lower $\eta $ regimes, $\eta = 0.02 $ or 0.1, and when $\mathit{Eo}$ exceeds a critical threshold, it is observed that a rising drop exhibits nonlinear lateral/tilting motion. In the higher $\eta $ regimes, $\eta = 0.1$, 1.94, 10 or 100, and when $\mathit{Eo}$ exceeds another critical threshold, it is found that a rising drop becomes unstable and breaks up into multiple drops. The type of breakup, either ‘dumbbell’, ‘intermediate’ or ‘toroidal’, depends intimately on $\eta $ and $\mathit{Eo}$.

Full textAbstract:
This paper describes a curator’s personal experience in a museum of art with several “auxiliary” archives of museum collections, in which various photographic objects are the most numerous. The paper underlines the issue of experts’ unpreparedness within museum institutions for managing and preserving photographic material, which is especially challenging when it exists in a heterogenous documentation cluster that has been reassembled multiple times. In an effort to preserve the conceptual integrity of the new/old archive, which will as much as possible mirror all earlier uses, interventions, manipulations, etc. of the material, as a sign of its pre- and post-acquisition biography (Edwards, Morton), and equally the history of the museum, it has been resorted to a top-to-bottom archival description that will reach the level of each individual item. In this way, the archival imperative of acknowledging the provenance and original order is not being betrayed, while at the same time we are ensuring the visibility of each individual photograph, which is described both as a document and as an artifact. Taking into consideration the fact that this kind of approach is not universally applicable, all of its recognized benefits and inherent limitations are presented. Finally, the paper briefly discusses the challenges of applying the same approach to a digital context.

This article interrogates principles of ethnography in education proposed by Mills and Morton: raw tellings, analytic pattern, vignette and empathy. This article adopts a position that is uncomfortable, unconventional and interesting. It involves a deterritorialization/ rupture of ethnography in education in order to reterritorialize a different concept: rhizoanalysis, a way to position theory and data that is multi-layered, complex and messy. Rhizoanalysis, the main focus of this article is not a method. It is an approach to research conditioned by a reality in which Deleuze and Guattari disrupt representation, interpretation and subjectivity. In this article, Multiple Literacies Theory, a theoretical and practical framework, becomes a lens to examine a rhizomatic study of a Korean family recently arrived to Australia and attending English as a second language classes. Observations and interviews recorded the daily lives of the family. The vignettes were selected by reading data intensively and immanently through a process of palpation, an innovative approach to educational research. Rhizoanalysis proposes to abandon the given and invent different ways of thinking about and doing research and what might happen when reading data differently, intensively and immanently, through Multiple Literacies Theory. Rhizoanalysis, a game-changer in the way research can be conducted, affords a different lens to tackle issues in education through research.

AimsAims Studies on literacy difficulties have mainly focused on children or adults who have a diagnosis of dyslexia. Some students enter university without such a diagnosis, but with literacy difficulties, and this may impact their ability to become independent learners and achieve academically. This exploratory study aims to employ a hybrid model for developing profiles for such individuals. The hybrid model encompasses the causal modelling framework (CMF; Morton & Frith, 1993), the proximal and distal causes of literacy difficulties (Jackson & Coltheart, 2001) and the conceptual framework for identification of dyslexia (Reid & Came, 2009).MethodIn this multiple case study design, three young adults with literacy difficulties were interviewed. Using narrative analysis, we compared the cases’ responses with the responses of a matched control student without literacy difficulties.FindingsThe main findings of the comparison suggested that the proposed hybrid model could be an effective way to highlighting potential obstacles to learning in those with literacy difficulties and would, therefore, be an invaluable tool for educational psychologists who work in adult educational settings.LimitationsThis is an exploratory study based on multiple case studies. A group study with more individuals should be conducted in order to further validate the proposed hybrid model.ConclusionsThe current study highlights the importance of understanding the psychosocial, as well as the cognitive and biological aspects of literacy difficulties, without claiming generalisability.

Abstract. Although contemporary geospatial science has made great progress, spatial data fusion of vector and raster data is still a problem in the geoinformation science environment. In order to solve the problem, this paper proposes a method which merges vector and raster data. Firstly, the row and column numbers of the raster data, and the X, Y values of the vector data are represented by Morton code in the C++ environment, respectively. Secondly, we establish the the raster data table and the vector data table in the Oracle database to store the vector data and the raster data. Third, this paper uses the minimum selection bounding box method to extract the top data of the building model. Finally, we divide the vector and raster data into four steps to obtain the fusion data table, and we call the fusion data in the database for 3D visualization. This method compresses the size of data of the original data, and simultaneously divides the data into three levels, which not only solves the problem of data duplication storage and unorganized storage, but also can realize vector data storage and the raster data storage in the same database at the same time. Thus, the fusion original orthophoto data contains the gray values of building roofs and the elevation data, which can improve the availability of vector data and the raster data in the 3D Visualization application.

There are a huge number of studies that measure kinematics, dynamics, the oxygen uptake and so on in human walking on the treadmill. Especially in walking on the splitbelt treadmill where the speed of the right and left belt is different, remarkable differences in kinematics are seen between normal and cerebellar disease subjects. In order to construct the gait adaptation model of such human splitbelt treadmill walking, we proposed a simple control model and made a newly developed 2D biped robot walk on the splitbelt treadmill. We combined the conventional limit-cycle based control consisting of joint PD-control, cyclic motion trajectory planning and a stepping reflex with a newly proposed adjustment of P-gain at the hip joint of the stance leg. We showed that the data of robot (normal subject model and cerebellum disease subject model) experiments had high similarities with the data of normal subjects and cerebellum disease subjects experiments carried out by Reisman et al. (2005) and Morton and Bastian (2006) in ratios and patterns. We also showed that P-gain at the hip joint of the stance leg was the control parameter of adaptation for symmetric gaits in splitbelt walking and P-gain adjustment corresponded to muscle stiffness adjustment by the cerebellum. Consequently, we successfully proposed the gait adaptation model in human splitbelt treadmill walking and confirmed the validity of our hypotheses and the proposed model using the biped robot.

Reablement services are approaches for maintaining and improving the functional independence of older adults. Previous reablement studies were conducted in a home environment. Due to the limited evidence on the effects of multicomponent interventions and reablement in a community-based context, this study aimed to develop and evaluate the effect of community-based physical–cognitive training, health education, and reablement (PCHER) among rural community-dwelling older adults with mobility deficits. The trial was conducted in rural areas of New Taipei City, Taiwan. Older adults with mild to moderate mobility deficits were recruited from six adult daycare centers, and a cluster assignment was applied in a counterbalanced order. The experimental group (n = 16) received a PCHER intervention, comprising 1.5 h of group courses and 1 h of individualized reablement training, while the control group (n = 12) underwent PCHE intervention, comprising 1.5 h of group courses and 1 h of placebo treatment. A 2.5-h training session was completed weekly for 10 weeks. The outcome measures contained the de Morton Mobility Index (DEMMI), the Saint Louis University Mental Status (SLUMS) Examination, the Barthel Index (BI), the Short Physical Performance Battery (SPPB), and the Canadian Occupational Performance Measure (COPM). The PCHER significantly improved the DEMMI, SLUMS, BI, SPPB, and COPM (all p < 0.05), with medium-to-large effect sizes. PCHER also showed an advantage over PCHE in terms of the SPPB (p = 0.02). This study verified that combining individualized reablement with group-based multicomponent training was superior to group courses alone in enhancing the functional abilities of community-dwelling older adults with mobility deficits.

Full textAbstract:
An experimental study of the structure of round buoyant turbulent plumes was carried out, limited to conditions in the self-preserving portion of the flow. Plume conditions were simulated using dense gas sources (carbon dioxide and sulfur hexafluoride) in a still and unstratified air environment. Velocity/mixture-fraction statistics, and other higher-order turbulence quantities, were measured using laser velocimetry and laser-induced fluorescence. Similar to earlier observations of these plumes, self-preserving behavior of all properties was observed for the present test range, which involved streamwise distances of 87–151 source diameters and 12–43 Morton length scales from the source. Streamwise turbulent fluxes of mass and momentum exhibited countergradient diffusion near the edge of the flow, although the much more significant radial fluxes of these properties satisfied gradient diffusion in the normal manner. The turbulent Prandtl/Schmidt number, the ratio of time scales characterizing velocity and mixture function fluctuations and the coefficient of the radial gradient diffusion approximation for Reynolds stress, all exhibited significant variations across the flow rather than remaining constant as prescribed by simple turbulence models. Fourth moments of velocity and velocity/mixture fraction fluctuations generally satisfied the quasi-Gaussian approximation. Consideration of budgets of turbulence quantities provided information about kinetic energy and scalar variance dissipation rates, and also indicated that the source of large mixture fraction fluctuations near the axis of these flows involves interactions between large streamwise turbulent mass fluxes and the rapid decay of mean mixture fractions in the streamwise direction.

For contemporary music in America and Europe, the 1970s were a time in which the old order was changing, giving place to a new avant-garde. In Germany, the Darmstädter Ferienkurse für Neue Musik was stagnating under the inept leadership of Ernst Thomas, savaged by the press and ridden with inner squabbling and politics. For 25 years a bastion of musical innovation and experimentation, Darmstadt now seemed little more than ‘the crumbling edifice of the avant-garde's chief fortress’. The focus was shifting to Paris, where, in 1977, IRCAM opened beneath the Centre Georges Pompidou. Led by Pierre Boulez and staffed by Luciano Berio, Vinko Globokar, Max Mathews, and Jean-Claude Risset, its stated mission was to reunite science and music and create new modes of performance. Across the Channel, the composers of the New Complexity (Brian Ferneyhough, James Dillon, Richard Barrett, and Chris Dench) were also redefining performance practice, focusing not on technology but on notation and its implications for virtuosity. And in America, different schools of musical thought were colliding in the streets and the academy. Leonard Bernstein delivered the Charles Eliot Norton lectures at Harvard, then presented his ‘unanswered question’ to the American public, on television, in 1976. And uptown and downtown were ensconced, with Milton Babbitt and Morton Feldman appointed to the faculties at the Juilliard School and the State University of New York at Buffalo, respectively. On both sides of the Atlantic, seminal artistic statements were being made, heralding the unruly adolescence of a new and disparate avant-garde no longer directly connected to the Second World War.

Full textAbstract:
In recent years, the increasing disparity between the data access speed of cache and processing speeds of processors has caused a major bottleneck in achieving high-performance 2-dimensional (2D) data processing, such as that in scientific computing and image processing. To solve this problem, this paper proposes new dual unit tile/line access cache memory based on a hierarchical hybrid Z-ordering data layout and multibank cache organization supporting skewed storage schemes. The proposed layout improves 2D data locality and reduces L1 cache misses and Translation Lookaside Buffer (TLB) misses efficiently and it is transformed from conventional raster layout by a simple hardware-based address translation unit. In addition, we proposed an aligned tile set replacement algorithm (ATSRA) for reduction of the hardware overhead in the tag memory of the proposed cache. Simulation results using Matrix Multiplication (MM) illustrated that the proposed cache with parallel unit tile/line accessibility can reduce both the L1 cache and TLB misses considerably as compared with conventional raster layout and Z-Morton order layout. The number of parallel load instructions for parallel unit tile/line access was reduced to only about one-fourth of the conventional load instruction. The execution time for parallel load instruction was reduced to about one-third of that required for conventional load instruction. By using 40 nm Complementary Metal-Oxide-Semiconductor (CMOS) technology, we combined the proposed cache with a SIMD-based data path and designed a 5 × 5 mm2 Large-Scale Integration (LSI) chip. The entire hardware overhead of the proposed ATSRA-cache was reduced to only 105% of that required for a conventional cache by using the ATSRA method.

Abstract Observing later-life health outcomes using a life-course model uncovers critical periods of influence. We investigated the relationship between five multi-component measures of childhood disadvantage (determined by Morton et al., 2022) and risk of cognitive impairment (determined by the Langa-Weir Classification) in later life. Data from the Health and Retirement Study (n= 9,509) were used. We conducted a multivariable parametric survival analysis to examine the relationships between the early life predictors of low socioeconomic status (SES), childhood impairments, risky adolescent behaviors, risky parental behaviors, and childhood chronic illness and the risk of developing later-life cognitive impairment between 2006 and 2016. We found that each additional indicator of low SES, risky adolescent behavior, and impairment in childhood increased the risk of developing cognitive impairment over the 10 years studied (HR=1.14, p < .05; HR=1.15, p < .05; HR=1.19, p < .05). Additional indicators of risky parental behaviors, however, were related to a smaller risk of developing cognitive impairment over time (HR=0.96, p < .05). Childhood chronic illness was not significantly associated with the risk of developing cognitive impairment. These results show that early-life factors might have long-term implications for the development of cognitive impairment in later life and display differential relationships with risk when parsed into competing categories. Measures of disadvantage indicating smaller risk may point to the resilience and plasticity of the brain in early life and highlight the need for the study of multiple life stages in order to track predictors of cognitive impairment throughout the life course.

Full textAbstract:
This paper, based mainly on astronauts’ first-person writings, historical documents, and my own ethnographic interviews with nine astronauts conducted between 2004 and 2020, explores how encountering the earth and other celestial objects in ways never before experienced by human beings has influenced some astronauts’ cosmological understandings. Following the work of Timothy Morton, the earth and other heavenly bodies can be understood as “hyperobjects”, entities that are distributed across time and space in ways that make them difficult for human beings to accurately understand, but whose existence is becoming increasingly detectable to us. Astronauts in outer space are able to perceive celestial objects from vantages literally unavailable on earth, which has often (but not always) had a profound influence on their understandings of humanity, life, and the universe itself. Frank Wright’s term, the “overview effect”, describes a cognitive shift resulting from seeing the Earth from space that increases some astronauts’ sense of connection to humanity, God, or other powerful forces. Following NASA convention (NASA Style Guide, 2012), I will capitalize both Earth and Moon, but will leave all quotations in their original style. The “ultraview effect” is a term I introduce here to describe the parallel experience of viewing the Milky Way galaxy from the Moon’s orbit (a view described reverently by one respondent as a “something I was not ready for”) that can result in strong convictions about the prevalence of life in the universe or even unorthodox beliefs about the origins of humanity. I will compare Morton’s ideas about humanity’s increased awareness of hyperobjects with Joye and Verpooten’s work on awe in response to “bigness”, tying both to astronauts’ lived experiences in order to demonstrate the usefulness of ethnographic data in this context, discuss how human experiences in outer space might influence religious practices and beliefs, and suggest that encounters with hyperobjects hold the potential to be socially beneficial.

Full textAbstract:
Turbulent plumes, which are seen in a wide number of industrial and natural flows, have been extensively studied; however, very little attention has been paid to plumes which have an internal mechanism for changing buoyancy. Such plumes arise in e.g. industrial chimneys, where species can react and change the density of the plume material. These plumes with chemical reaction are the focus of this study. An integral model describing the behaviour of a plume undergoing a second-order chemical reaction between a component in the plume (A) and a component in the surrounding fluid (B), which alters the buoyancy flux, is considered. The behaviour of a reactive plume is shown to depend on four dimensionless groups: the volume and momentum fluxes at the source, the parameter ϵ which indicates the additional buoyancy flux generated by the reaction and γ which is a dimensionless rate of depletion of species B. Additionally, approximate analytical solutions are sought for a reactive plume rising from a point source of buoyancy when species B is in great excess. These analytical results show excellent agreement with numerical simulations. It is also shown that the behaviour of a reactive plume in the far field is equivalent to an inert plume issuing from a virtual source downstream of the real source, and the dependence of the location of the virtual source on ϵ and γ is discussed. The effects of varying the volume flux at the source and the Morton source parameter Γ0 are further investigated by solving the full governing equations numerically. These solutions indicate that ϵ is important in determining the buoyancy generated by the reaction, and the length scale over which this reaction occurs depends on γ when γ > 1. It is also shown that when the dimensionless buoyancy ϵ < − 1, the reaction can cause the plume to collapse.

Full textAbstract:
A single bubble is placed in a solid-body rotating flow of silicon oil. From the measurement of its equilibrium position, lift and drag forces are determined. Five different silicon oils have been used, providing five different viscosities and Morton numbers. Experiments have been performed over a wide range of bubble Reynolds numbers (0.7 ≤ Re ≤ 380), Rossby numbers (0.58 ≤ Ro ≤ 26) and bubble aspect ratios (1 ≤ χ ≤ 3). For spherical bubbles, the drag coefficient at the first order is the same as that of clean spherical bubbles in a uniform flow. It noticeably increases with the local shear S = Ro−1, following a Ro−5/2 power law. The lift coefficient tends to 0.5 for large Re numbers and rapidly decreases as Re tends to zero, in agreement with existing simulations. It becomes hardly measurable for Re approaching unity. When bubbles start to shrink with Re numbers decreasing slowly, drag and lift coefficients instantaneously follow their stationary curves versus Re. In the standard Eötvös–Reynolds diagram, the transitions from spherical to deformed shapes slightly differ from the uniform flow case, with asymmetric shapes appearing. The aspect ratio χ for deformed bubbles increases with the Weber number following a law which lies in between the two expressions derived from the potential flow theory by Moore (J. Fluid Mech., vol. 6, 1959, pp. 113–130) and Moore (J. Fluid Mech., vol. 23, 1965, pp. 749–766) at low- and moderate We, and the bubble orients with an angle between its minor axis and the direction of the flow that increases for low Ro. The drag coefficient increases with χ, to an extent which is well predicted by the Moore (1965) drag law at high Re and Ro. The lift coefficient is a function of both χ and Re. It increases linearly with (χ − 1) at high Re, in line with the inviscid theory, while in the intermediate range of Reynolds numbers, a decrease of lift with aspect ratio is observed. However, the deformation is not sufficient for a reversal of lift to occur.

The γ-brass Hume-Rothery [1] phases which adopt at VEC values near about 21/13 presently attract attention due to their structural complexity and challenge for the understanding of the underlying stabilization mechanism. Morton, by electron microscopy studies, revealed that the γ-brass regions of Cu-Zn, Ni-Zn and Pd-Zn do not only accommodate the γ-brass phase but also a bundle of structurally related, complex phases with lower symmetry than that of the γ-phase. A bundle of γ-brass related phases in the Zn-rich region of the Ni-Zn, Pd-Zn, Pt-Zn phase diagram is investigated. Their structures have been refined from single crystal X-ray diffraction data in the conventional 3D space group using supercells [2,3]. In the course of a previous investigation of the Pd-Zn system, the structures of two γ-brass related composite compounds- Pd24.3Zn75.7 and Pd21.2Zn78.8 have been described with the (3+1) dimensional space description (superspace group Xmmm(00γ)0s0 with the following lattice parameters, a = 12.929(3) Å, b = 9.112(4) Å, c = 2.5631(7) Å, q = 8/13 c* and a = 12.909(3) Å, b = 9.115(3) Å, c = 2.6052(6) Å, q = 11/18 c*, respectively) [3]. The aim of this study is to represent the structure of these previously reported phases in a coherent, modulated description to make them more readily comparable. A refinement model with a variety of modulation vectors allows to refine any intergrowth structure in the Zn rich region of the M-Zn (M=Ni,Pd,Pt) system. In order to gain an insight into expressions, cause and mechanism and structure-composition relationship for such phases, we also study the impact of substitution on the evolution of the structure of ternary derivatives of M-Zn composite compounds by the use of (3+1) formalism. For instance, substitution of zero-valent palladium and bi-valent zinc by zero-valent platinum in the structure of Pd24.3Zn75.7. This presentation will discuss about the understanding of the complexity of the atomic arrangement through the various modulation which correlates with the variation of composition of the binary and ternary phases.
