description: Vortices have been postulated at a range of size scales in the universe including at the stellar size-scale. Whilst hydrodynamically simulating the wind from an asymptotic giant branch (AGB) star moving through and sweeping up its surrounding interstellar medium (ISM), we have found vortices on the size scale of 10^-1 pc to 10^1 pc in the wake of the star. These vortices appear to be the result of instabilities at the head of the bow shock formed upstream of the AGB star. The instabilities peel off downstream and form vortices in the tail of AGB material behind the bow shock, mixing with the surrounding ISM. We suggest such structures are visible in the planetary nebula Sh 2-188.

description: Researchers and practitioners in the field of psychology frequently use parent and teacher rating scales in the assessment, diagnosis, and treatment of young children. However, research has shown that agreement between parents and teachers on rating scales is low to moderate. The present study examined this phenomenon, termed "informant discrepancy", for the Behavior Rating Inventory of Executive Functions (BRIEF) and the Social Skills Improvement System (SSIS). Parents and teachers completed these scales for the same sample of 73 Kindergarten children. Results indicated that parent-teacher agreement was low at the scale and item levels, within-informant correlations were higher than between-informant correlations, mean differences in parent and teacher ratings may be explained by differences in the home and school contexts, and informants identified different children as having significant problems with executive functions and social skills. Implications of the findings for research and practice are discussed.

description: A distinct signature of compact extra dimensions would be a Kaluza-Klein tower of gravitational waves. Motivated by this prospect, we compute the corresponding spectrum on a warped toroidal background. We evaluate in particular the impact of the warp factor on the spectrum. To that end, we use the complete warp factor H of standard string compactifications, generated by D-branes and orientifolds, thus connecting to recent works on stringy de Sitter constructions. The problematic region close to an orientifold where H < 0 leads to unphysical tachyonic modes in the spectrum. We develop tools that overcome this difficulty and lead to a tachyon-free spectrum. We show, in particular, that the warp factor can lower the first Kaluza-Klein mass by at least 69%.

Application of decision analysis to seismic rehabilitation of historic buildings : a case study of rehabilitation of Stanford University Memorial Church
Creators: name: Kwan, Joanna
Publisher: name: University of British Columbia
Year: 2009

description: The construction of an expected value decision model for selecting seismic retrofit schemes for a historic building is demonstrated through a case study. Net Present Costs (NPC) are used to rank the retrofit options. NPC is defined as the sum of the initial investment cost and the present expected value of the total future damage costs. Four options are assumed to be proposed to upgrade the Stanford Memorial Church in 1980. Option 1 is to do nothing in terms of seismic strengthening, whereas options 2 to 4 are seismic strengthening the Church with increasing level of safety and costs. Seismic data are selected to derive a set of earthquake probabilities. Damage probabilities and damage costs, including direct costs, indirect costs, and costs of life, are estimated. A discount rate and a life span are chosen to discount the future damage costs to present expected values. Option 3, strengthening the Church to building integrity standard without removing the unreinforced masomy (URM) walls, has the lowest NPC and is considered as the optimal option. If it had been recommended and adopted in 1980, about 40% of the accumulative expense from 1980 to 1990 would have been saved. A sensitivity analysis is carried out in order to determine the importance of variables that are only crudely estimated. In general, the outcome is insensitive to changes in seismic data, damage costs, discount rates and life spans when the changes are within reasonable ranges. To obtain higher accuracy, attention should be paid to estimating the probabilities and damage costs of moderate to large earthquakes (MIvil V to IX) rather than that of great earthquakes (MIvil X and above). The outcome is sensitive to the expected reduction in damage due to retrofits. Better methods for predicting structural behavior is needed. More research in developing guidelines for estimating future damages and social impacts is recommended.

description: Born in Sydney, Australia, on April 20, 1939, Chris Heyde shifted his interest from sport to mathematics thanks to inspiration from a schoolteacher. After earning an M.Sc. degree from the University of Sydney and a Ph.D. from the Australian National University (ANU), he began his academic career in the United States at Michigan State University, and then in the United Kingdom at the University of Sheffield and the University of Manchester. In 1968, Chris moved back to Australia to teach at ANU until 1975, when he joined CSIRO, where he was Acting Chief of the Division of Mathematics and Statistics. From 1983 to 1986, he was a Professor and Chairman of the Department of Statistics at the University of Melbourne. Chris then returned to ANU to become the Head of the Statistics Department, and later the Foundation Dean of the School of Mathematical Sciences (now the Mathematical Sciences Institute). Since 1993, he has also spent one semester each year teaching at the Department of Statistics, Columbia University, and has been the director of the Center for Applied Probability at Columbia University since its creation in 1993. Chris has been honored worldwide for his contributions in probability, statistics and the history of statistics. He is a Fellow of the International Statistical Institute and the Institute of Mathematical Statistics, and he is one of three people to be a member of both the Australian Academy of Science and the Australian Academy of Social Sciences. In 2003, he received the Order of Australia from the Australian government. He has been awarded the Pitman Medal and the Hannan Medal. Chris was conferred a D.Sc. honoris causa by University of Sydney in 1998. Chris has been very active in serving the statistical community, including as the Vice President of the International Statistical Institute, President of the Bernoulli Society and Vice President of the Australian Mathematical Society. He has served on numerous editorial boards, most notably as Editor of Stochastic Processes and Their Applications from 1983 to 1989, and as Editor-in-Chief of Journal of Applied Probability and Advances in Applied Probability since 1990.

description: The aim of this dissertation has been the study of the specific features of the Passion’s narratives in the Gospel of Luke in relation to the other two Synoptics, Mark and Matthew, as well as the similarities they share with the Gospel of John. We have examined elements mentioned only in the Gospel of Luke. We moved on to the analysis of Luke’s extraordinary material and the sources he seems to have derived this information from. Moreover, we have referred to the views of various researchers on this particular topic. We have also attached a table presenting the common passages of the Passion’s narratives in Luke’s and John’s and we have tried to justify the reasons according to which these two evangelists show such similarities. We dealt with the historical aspect of the events of that era without overlooking the divine force that has led to the writing of the gospels
Mass-Loaded Flows

description: A key process within astronomy is the exchange of mass, momentum, and energy between diffuse plasmas in many types of astronomical sources (including planetary nebulae, wind-blown bubbles, supernova remnants, starburst superwinds, and the intracluster medium) and dense, embedded clouds or clumps. This transfer affects the large scale flows of the diffuse plasmas as well as the evolution of the clumps. I review our current understanding of mass-injection processes, and examine intermediate-scale structure and the global effect of mass-loading on a flow. I then discuss mass-loading in a variety of diffuse sources.

Στο πρώτο τμήμα εξετάζεται ο τρόπος με τον οποίο σκιαγραφείται στο πρώτο βιβλίο της ιστορίας του Τίτου Λιβίου η μορφή του πρώτου βασιλιά της Ρώμης και επιπλέον η σημασία που αυτός είχε ως παράδειγμα για τους αναγνώστες του Ab Urbe Condita. Στο δεύτερο τμήμα της εργασίας γίνεται μία προσπάθεια να παρουσιαστεί − με βάση τα ιστορικοπολιτικά δεδομένα της εποχής της συγγραφής του έργου − ο τρόπος με τον οποίο ο Αύγουστος επιχείρησε να συνδεθεί με τον Ρωμύλο και να τον εντάξει στο πολιτικό και πολιτιστικό του πρόγραμμα. Τέλος, στο τρίτο μέρος της παρούσας εργασίας τίθεται το ερώτημα αν οι αναγνώστες του Λιβίου μπορούσαν να συνειδητοποιήσουν τη σύγχρονη ιστορική διάσταση της αφήγησης του ιστορικού γύρω από τον ιδρυτή της Ρώμης και να διακρίνουν πίσω από τη μορφή του Ρωμύλου εκείνη του Αυγούστου
description: The aim of this study is to present the figure of Romulus, the founder of Rome, in the history of Livy and the connection that Augustus attempted between himself and Romulus. In the first part the study examines the way of presentation of Romulus in the first book of Livy’s history and also the importance of the first king as an example for the readers of Ab Urbe Condita. The second part presents − based on the historical and political reality of the time of the composition of Livy’s history − the connection between Augustus and Romulus and the accession of the first king in the political and cultural program of the new leader of Rome. Finally, in the third part of this study is posed the question if the readers of Livy’s history could realize the contemporary historical dimension of Livy’s narration about the founder of Rome and if they could distinguish the figure of Augustus behind that of Romulus

description: We present a study of the application of a variant of a recently introduced heuristic algorithm for the optimization of transport routes on complex networks to the problem of finding the optimal routes of communication between nodes on wireless networks. Our algorithm iteratively balances network traffic by minimizing the maximum node betweenness on the network. The variant we consider specifically accounts for the broadcast restrictions imposed by wireless communication by using a different betweenness measure. We compare the performance of our algorithm to two other known algorithms and find that our algorithm achieves the highest transport capacity both for minimum node degree geometric networks, which are directed geometric networks that model wireless communication networks, and for configuration model networks that are uncorrelated scale-free networks.

description: Energy poverty is a complex and multidimensional phenomenon caused by various factors. It is defined as a situation in which households are unable to access essential energy services and products. Despite widespread recognition and discussion of the topic, there are still several gaps in knowledge and practice. One aspect of energy poverty that remains largely unexplored in Europe is rural energy poverty, receiving limited attention despite being more prevalent than in urban contexts. Additionally, in the pursuit of a clean and just transition, rural areas in Europe are often left behind, even though rural populations are at a significantly higher risk of facing poverty and social exclusion. This phenomenon is particularly pronounced in Central and Eastern Europe (CEE), Southern Eastern Europe (SEE), and Southern Europe (SE) countries, where populations are more susceptible to energy poverty.

This report follows a multi-step approach with the objective of addressing this gap and upgrading the framework on rural and peri-urban energy poverty. It consists of a summary of extensive desk research in which more than 80 relevant scientific and grey literature sources are analysed to review current knowledge and practices in energy poverty research and policy in rural and peri-urban areas. The outcomes of the literature review were utilised to formulate an online survey of relevant stakeholders to obtain broader insights into existing needs and barriers, as well as proposed solutions for the implementation of policies for energy efficiency in vulnerable rural and peri-urban areas. The acquired insights feed into the development of the Composite Energy & Transport Poverty Indicator (CEPTI) to provide a practical tool for identifying areas more highly exposed to energy poverty and offering an approximation of the experience of those affected by energy and transport poverty. Furthermore, a set of energy audits was conducted in the pilot regions of RENOVERTY to identify the distinct characteristics of dwellings found within rural and peri-urban areas of Europe.

This document presents the main outcomes of RENOVERTY activities which aim to provide a robust, holistic and up-to-date framing of rural energy poverty in the European Union (EU). This information informs relevant stakeholders regarding the specific characteristics of rural areas when it comes to energy efficiency and energy poverty and assists subsequent activities of the project that seek to enhance the uptake of energy efficiency and address energy poverty in rural contexts.
Characterization and toxicity of pulp and paper mill sludge leachates
Creators: name: Perera, Dharshini Marian
Publisher: name: University of British Columbia
Year: 2009

description: The main objective of this study was to investigate the characteristics of pulp and paper mill sludge leachates and to assess their toxicity. Sludges from three mills in British Columbia were subjected to aqueous leaching in laboratory columns at different pH levels to evaluate the relationship between leachability of the contaminants and pH. Leachates were fractionated by ultrafiltration into different molecular size fractions and the leachable contaminants were characterized for carbon content, colour and fluorescence properties, chlorinated phenolics, resin acids, metals and AOX content. The toxicity of the leachates was assessed by conducting laboratory bioassays on Daphnia magna and using the Microtox bioassay. The bioconcentration potential of the chlorinated phenolic compounds was measured using fresh water leeches. Leachates were also collected from sludge previously applied to a test site and analyzed for characteristics and toxicity to investigate the feasibility of applying pulp and paper mill sludge to forest land as an organic fertilizer. Leachability of carbon varied considerably between sludge leachates from different mills. The soluble carbon content of subsamples of the same sludge leachate varied between one to another, indicating the highly variable nature of these sludge leachates. Leachates of different molecular size fractions had different colour and fluorescence properties. No consistent relationship was found between the carbon distribution in the fractions and colour or fluorescence suggesting that colour or fluorescence cannot be used as an estimate of the total dissolved carbon or the predominance of any molecular size fraction in a sludge leachate. Leachability of contaminants was affected by pH. Generally the total concentration of chlorinated phenolics and resin acids increased with increasing pH for sludge leachates for all the mills. At higher pH’s, there was a tendency for the chlorinated phenolics with the lower chlorination number to leach out more. The identifiable chlorinated phenolics were a very small percentage (<0.5 %) of the adsorbable organic halides (AOX) in the leachates. The chlorinated phenolic concentrations in the sludge leachates were low when compared to concentrations found in treated effluents. Analysis of individual molecular fractions revealed the presence of low molecular weight chlorinated phenolics and resin acids (<1000 Daltons) in the high molecular (>1000 Daltons) weight fraction which indicated adsorption to these larger molecules. Toxicity studies with the two bioassays revealed different sensitivities. Generally the Microtox bioassay was more sensitive than the D.magna bioassay. The bioavailability of the chlorinated compounds in the sludge leachates was confirmed by some high bioconcentration factors in freshwater leeches.

Τα δίκτυα της νέας γενιάς υπόσχονται υψηλότατες ταχύτητες και απεριόριστη χωρητικότητα, στοιχεία που θα φέρουν σημαντικές αλλαγές στη διαδικτυακή καθημερινότητά μας. Η τεχνολογία 5G είναι ένα συμφωνημένο σύνολο προτύπων που καθορίζονται από την Διεθνή Ένωση Τηλεπικοινωνιών (ITU) και την 3GPP. Αμφότεροι οι οργανισμοί συνεργάζονται με εταιρείες και φορείς υλικού για να διαμορφώσουν τα νέα δίκτυα 5G. Πολλές είναι οι υποψήφιες τεχνολογίες για την υλοποίηση των δικτύων 5ης γενιάς αλλά η κυριότερη θα λέγαμε ότι είναι η «εκμετάλλευση» της ζώνης συχνοτήτων από 30 GHz έως 300 GHz, γνωστή και ως mmWave. Πανεπιστήμια και εταιρείες εργάστηκαν από κοινού για το σχεδιασμό προσομοιωτών που στηρίζονται στην τεχνολογία των χιλιοστομετρικών κυμάτων. Στα πλαίσια αυτής της διπλωματικής εργασίας, αρχικά παρουσιάζονται οι μηχανισμοί διάδοσης της Η/Μ ακτινοβολίας στο χώρο και γίνεται μία εισαγωγή στα mmWave κύματα και τους μηχανισμούς διάδοσης τους.

Συγκεκριμένα γίνεται λεπτομερής ανάλυση δύο αρκετά σημαντικών προσομοιωτών, του προσομοιωτή δικτύων διακριτών – γεγονότων NS – 3 και ενός καινοτόμου ρεαλιστικού μοντέλου καναλιού βασισμένο σε πραγματικές μετρήσεις, ΝYUSIM σε συχνότητες από 28 GHz έως 73 GHz
description: 2020 is considered as the year that 5G technology will be established world-wide. New generation networks promise higher speeds and unlimited capacity, characteristics that will bring significant changes to our everyday life. 5G technology is an agreed set of standards defined by the International Telecommunications Union (ITU) and 3GPP. Both organizations collaborate with companies to form the new 5G networks. Many technologies are candidate for the implementation of 5th generation networks but the main one we would say is the exploitation of the bandwidth from 30 GHz to 300 GHz, also known as mmWave. Universities and companies have worked together to design simulators based on millimeter wave technology. Within the framework of this master thesis, firstly, the mechanisms of propagation of the electromagnetic radiation in space are presented and then the advantages – disadvantages of the mmWaves are mentioned. The main purpose of this thesis, is to study simulators for 5G networks. Specifically, a detailed analysis of the two significant simulators is done; a discrete-event network simulator NS – 3 and a novel channel simulation software named NYUSIM, which has been developed based on extensive real-world wideband propagation channel measurements at multiple millimeter-wave (mmWave) frequencies from 28 to 73 GHz
Predictions for "mu -> e gamma" in SUSY from non trivial Quark-Lepton complementarity

description: We compute the effect of non diagonal neutrino mass in l_i -> l_j gamma in SUSY theories with non trivial Quark-Lepton complementarity and a flavor symmetry. The correlation matrix V_M=U_{CKM}U_{PMNS} is such that its (1,3) entry, as preferred by the present experimental data, is zero. We do not assume that $V_M$ is bimaximal. Quark-Lepton complementarity and the flavor symmetry strongly constrain the theory and we obtain a clear prediction for the contribution to mu -> e gamma and the tau decays tau -> e gamma and tau -> mu gamma. If the Dirac neutrino Yukawa couplings are degenerate but the low energy neutrino masses are not degenerate, then the lepton decays are related among them by the V_M entries. On the other hand, if the Dirac neutrino Yukawa couplings are hierarchical or the low energy neutrino masses are degenerate, then the prediction for the lepton decays comes from the U_{CKM} hierarchy.

description: Nowadays, societies have become more multicultural, so teachers are facing this phenomenon in their classrooms. All schools today have foreign students, in this study we focused on multicultural schools where foreign students are in a bigger percentage. In this work we will investigate the teachers’ beliefs and their willingness to change their teaching methods. In the theoretical part, we will do a literature review and we will analyze previous studies relative to our subject. Then, we will do an extended research in our subject and what teachers believe about their students. Specifically, if teachers expect that their students will succeed or not in school. When we have the answered questionnaire, we will do a quantity and quality analysis in our results and we will notice the general mood in schools. More precisely, the collaboration in classrooms, what groups the teacher makes and if the teacher makes discriminations. At the end, we have the conclusions of our research from the questionnaire answers in combination with the opinions of the participants

description: In a previous paper (Avotina et al.,Phys. Rev. B Vol.71, 115430 (2005)) we have shown that in principle it is possible to image the defect positions below a metal surface by means of a scanning tunnelling microscope. The principle relies on the interference of electron waves scattered on the defects, which give rise to small but measurable conductance fluctuations. Whereas in that work the band structure was assumed to be free-electron like, here we investigate the effects of Fermi surface anisotropy. We demonstrate that the amplitude and period of the conductance oscillations are determined by the local geometry of the Fermi surface. The signal results from those points for which the electron velocity is directed along the vector connecting the point contact to the defect. For a general Fermi surface geometry the position of the maximum amplitude of the conductance oscillations is not found for the tip directly above the defect. We have determined optimal conditions for determination of defect positions in metals with closed and open Fermi surfaces.

Capillary menisci between particles absorbed at a liquid-fluid interface
Creators: name: Hou, Linda
Publisher: name: University of British Columbia
Year: 2009

description: One aspect of the stability of solids-stabilized emulsions was indicated by Denkov et al. (8) who reported that the capillary pressure required for an emulsion droplet’s liquid to squeeze between the interfacial particles and come into contact with another droplet’s free liquid interface must be overcome and provides a barrier to the thinning of the film between droplets. In light of the work done by Denkov et al., the objective of the thesis has been to determine the effect several factors such as particle size, separation distance, wettability, fluid properties, and contact angle hysteresis have on emulsion stability, represented in terms of capillary pressures, using a two-layer particle model for coalescence. Two general models were developed, one which is based on a uniform layer of spherical particles adsorbed on a fluid-fluid interface, and the other, a two dimensional analogue, in which parallel, horizontal cylinders are situated on the interface. Numerical techniques were applied in the solution of both models since no simplification was made by the neglect of gravity as is found in similar models (8, 11, 12). As a consequence, the models can be used to describe macroscopic systems whose characteristic dimensions are well above the micron scale. A corresponding experimental system employing parallel cylinders was then constructed and used to generate capillary pressures and meniscus profiles for comparison with the computed model results. The model results agree with the experimental findings in the literature that the smaller the particles, the closer the packing of particles, or the rougher the solids are, the more stable the emulsions. Furthermore, a decrease in the Bond number or a decrease in wettability of the particles to the disperse phase would increase stability based on capillary pressure considerations. Overall trends for the cylinders model and the spheres model were similar. The contact angles which yield optimal stability from capillary and thermodynamic considerations lie in the range of 90°≤θ≤180°. The study revealed that good agreement between the model and the experimental measurements was obtained when apparent contact angles, which take into account hysteresis, were used to generate the model profiles for each meniscus.

description: Young children readily use syntactic cues for word learning in structurally-simple contexts (Naigles, 1990).  However, developmental differences in children's language processing abilities might interfere with their access to syntactic cues when novel words are presented in structurally-challenging contexts.  To understand the role of processing on syntactic bootstrapping, we used an eye-tracking paradigm to examine children's fast-mapping abilities in active (structurally-simple) and passive (structurally-complex) sentences.  Actions after sentences indicated children were more successful mapping words in passive sentences when novel words were presented in NP2 ("The seal will be quickly eaten by the blicket") than when novel words were presented in NP1 ("The blicket will be quickly eaten by the seal"), indicating presenting more prominent nouns in NP1 increases children's agent-first bias and sabotages interpretation of passives.  Later recall data indicate children were less likely to remember new words in structurally-challenging contexts.
Temporal Variations in Fibril Orientation

description: We measure variations in orientation of fourteen dynamic fibrils as a function of time in a small isolated plage and nearby network using a 10-min time sequence of H-alpha filtergrams obtained by the Dutch Open Telescope. We found motions with average angular velocities of the order of 1 deg/min suggesting systematic turning from one limit position to another, particularly apparent in the case of fibrils with lifetimes of a few minutes. Shorter fibrils tend to turn faster than longer ones, which we interpret as due to vortex flows in the underlying granulation that twist magnetic fields.

Transatlantic Validation: American Interest and Interpretation of the Gordon Riots

description: This project examines American interest and interpretation of the 1780 London-based Gordon Riots during the American Revolution.  Patriot and Loyalist newspapers and personal correspondence is reviewed and analyzed to demonstrate broad interest in the British domestic disturbance and usage of the riots and the government's response to affirm support for Americans' particular position on the war for independence.  This interest and interpretation is confirmation of a continued transatlantic dialogue and spread of information post-signing of the Declaration of Independence, and recovers an instance of continued interconnectedness between the British and American publics that informed Patriots and Loyalists' identities and ideologies during the war.

description: Η χρόνια αποφρακτική πνευμονοπάθεια είναι μια σύνθετη διαταραχή που επηρεάζει κυρίως τους πνεύμονες και χαρακτηρίζεται από την ύπαρξη τοπικής-πνευμονικής, αλλά και συστηματικής φλεγμονής, οι οποίες προάγουν την ανάπτυξη καρδιαγγειακών και άλλων μη πνευμονικών συννοσηροτήτων. Οι αναστολείς του μετατρεπτικού ενζύμου της αγγειοτενσίνης και οι αναστολείς των υποδοχέων αγγειοτενσίνης αποτελούν φάρμακα που χρησιμοποιούνται ευρέως για τη θεραπεία καρδιαγγειακών παθήσεων, με όλο και αυξανόμενο αριθμό δεδομένων να υποδεικνύουν πιθανά οφέλη σε ασθενείς με χρόνια αποφρακτική πνευμονοπάθεια. Σκοπός της παρούσας ανασκόπησης είναι η καταγραφή της συσχέτισης του συστήματος ρενίνης-αγγειοτενσίνης με την παθοφυσιολογία της χρόνιας αποφρακτικής πνευμονοπάθειας και η παρουσίαση του συνόλου των βιβλιογραφικών δεδομένων σχετικά με τις πιθανές επιδράσεις των αναστολέων του συστήματος ρενίνης-αγγειοτενσίνης (αναστολείς μετατρεπτικού ενζύμου αγγειοτενσίνης, αναστολείς υποδοχέων αγγειοτενσίνης) στη νόσο
description: Chronic obstructive pulmonary disease (COPD) is a complex disorder that primarily affects the lungs and is characterized not only by local pulmonary, but also by systemic inflammation which promotes the development of extrapulmonary and cardiovascular co-morbidities. Angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) are widely used drugs in the treatment of cardiovascular diseases, with growing evidence suggesting potential benefits in COPD patients. The purpose of this review is to describe the relation of renin–angiotensin system (RAS) with COPD pathophysiology and to present all the bibliographic data regarding the potential role of RAS blockers (ACE inhibitors and ARBs) in COPD
Configuration-Space Location of the Entanglement between Two Subsystems

description: In this paper we address the question: where in configuration space is the entanglement between two particles located? We present a thought-experiment, equally applicable to discrete or continuous-variable systems, in which one or both parties makes a preliminary measurement of the state with only enough resolution to determine whether or not the particle resides in a chosen region, before attempting to make use of the entanglement. We argue that this provides an operational answer to the question of how much entanglement was originally located within the chosen region. We illustrate the approach in a spin system, and also in a pair of coupled harmonic oscillators. Our approach is particularly simple to implement for pure states, since in this case the sub-ensemble in which the system is definitely located in the restricted region after the measurement is also pure, and hence its entanglement can be simply characterised by the entropy of the reduced density operators. For our spin example we present results showing how the entanglement varies as a function of the parameters of the initial state; for the continuous case, we find also how it depends on the location and size of the chosen regions. Hence we show that the distribution of entanglement is very different from the distribution of the classical correlations.

description: The poems in this collection explore the ways that we, as humans, both relate to and attempt to separate from our own bodies, as well as how we are shaped (and sometimes trapped) by heredity. These expansive concepts are reflected in lyric form, with recurring images of skin, water, blood, and birth connecting a range of narrative material. Throughout, an almost tribal identification with familial mythology conflicts with the desire for bodily agency, the need to claim, impossibly, control over our physical beings.
