description: The reconstruction of quantum states from a sufficient set of experimental data can be achieved with arbitrarily weak measurement interactions. Since such weak measurements have negligible back-action, the quantum state reconstruction is also valid for the post-selected sub-ensembles usually considered in weak measurement paradoxes. It is shown that post-selection can then be identified with a statistical decomposition of the initial density matrix into transient density matrices conditioned by the anticipated measurement outcomes. This result indicates that it is possible to ascribe the properties determined by the final measurement outcome to each individual quantum system before the measurement has taken place. The ``collapse'' of the pure state wavefunction in a measurement can then be understood in terms of the classical ``collapse'' of a probability distribution as new information becomes available.

A case for the Danish element in Northern American
Creators: name: Woods, Howard Bruce
Publisher: name: University of British Columbia
Year: 2011

description: Less than four decades ago it was thought that there was no substratum influence on the English language spoken in America. It had been noted that the Indians gave a few words to English and that there were small "pocket" colonies formed by the Germans in south-eastern Pennsylvania, the French in south-eastern Louisiana, the Spaniards in the Southwest, and ethnic groups in the large cities. Only more recently have scholars begun to see the important role that the speakers of continental Germanic languages have had in forming the speech patterns of American English. More than fifteen million immigrants whose mother tongue was a Germanic language other than English have settled in what is now the North American Midland, Northern, and Canadian dialectal regions. These immigrants and their many offspring formed the major linguistic group for many towns and vast rural areas and were second to the English speaking group in most other cities and areas. Much research has already been done on the German linguistic influence in North America and the results are generally accepted by linguists today. This thesis will concentrate on the Scandinavian element which has been sorely neglected to this date. The methods used have been many. The first method was much of the nature of collecting curiosity items: during my two years as an English teacher and translator in Denmark, I collected those items which seemed common to Danish and North American. Later, sources concerning Germanic language influence in America were consulted. In addition, a study of the North American and British dialects was made. It should also be noted that continual contact with the Danish-Canadians in Vancouver was maintained. The mixing and interference of Danish and English here must be closely reminiscent of the language contact and interference in Minnesota one century ago. The problem involved was mainly that of separation of identity. An item might have found its source in German, Dutch, Yiddish, or an English dialect if not in a combination of any of the above. A further separation difficulty comes from the close historical affiliation of Danish and English and the previous mixing of Danish into English during the Viking era. There are minor influences from Danish in Northern American English phonology, morphology (mainly word-compounding), and syntax (with such cases as the attributive noun). The chief contributions can be found in idiomatic expressions formed from loan translations, loan shifts, and loan creations. Word frequency is also affected by the Scandinavian substratum as are personal names and place-names.

description: We present an algebraic study of a kind of quantum systems belonging to a family of superintegrable Hamiltonian systems in terms of shape-invariant intertwinig operators, that span pairs of Lie algebras like $(su(n),so(2n))$ or $(su(p,q),so(2p,2q))$. The eigenstates of the associated Hamiltonian hierarchies belong to unitary representations of these algebras. It is shown that these intertwining operators, related with separable coordinates for the system, are very useful to determine eigenvalues and eigenfunctions of the Hamiltonians in the hierarchy. An study of the corresponding superintegrable classical systems is also included for the sake of completness.

description: Brillouin light scattering spectroscopy from so-called standing spin waves in thin magnetic films is often used to determine the magnetic exchange constant. The data analysis of the experimentally determined spin-wave modes requires an unambiguous assignment to the correct spin wave mode orders. Often additional investigations are needed to guarantee correct assignment. This is particularly important in the case of Heusler compounds where values of the exchange constant vary substantially between different compounds. As a showcase, we report on the determination of the exchange constant (exchange stiffness constant) in Co$_2$MnSi, which is found to be $A=2.35\pm0.1$ $μ$erg/cm ($D=575\pm20$ meV Å$^2$), a value comparable to the value of the exchange constant of Co.
Distributed computing and communication in peer-to-peer networks

Subjects: Distributed systems and algorithms

description: Traditional distributed computing systems are typically complex to implement and costly to maintain. Furthermore, little comparative work has been done to understand the performance and usability of these systems for their own sake as well of that of new approaches that eventuate. The work presented herein addresses both of these problems by describing the design and implementation of CompTorrent, a simple to implement and maintain decentralised peer-to-peer computing network, based on techniques used in other, non-computing peer-to-peer systems. This research also describes a new framework (WAN-DC) suitable for the comparison of wide area distributed computing systems. CompTorrent is compared with BOINC and Condor, two traditional distributed computing systems, using the WAN-DC framework on the same cluster hardware. WAN-DC consists of a baseline to quantify the size of the cluster hardware followed by a set of well-known algorithms including calculations of the Mandelbrot set, a conversion of video formats (Transcode) and a ray-tracing of a benchmarking scene (POV- Ray). Other experiments include determining the systems underlying overhead with work units of no load (No Work), as well as work units of ranging sizes in order to measure where a system becomes acceptably efficient. This last test, One Second, is particularly useful when comparing different systems and approaches. Results show that CompTorrent maintains a performance range between that of BOINC and Condor for all cluster node sizes for the POV-Ray experiment. Transcode shows CompTorrent is between or better than BOINC and Condor in 50% of cases and, whilst worse in the other half of experiments, it was only by approximately 15% in the worst case. Mandelbrot showed results between both distributed systems and, similarly to POV-Ray, No Work behaves either between or better than the results of both BOINC and Condor. These, and other, results described within, show that that a distributed processing system based on a decentralised, peer-to-peer network can provide similar results to distributed processing systems based on traditional client/server networking architectures. This work demonstrates a convergence of peer-to-peer and distributed computing systems which while considered as certain as "death and taxes" (Foster & Iamnitchi 2003) has not, until now, been formally demonstrated in an academic setting for general purpose distributed computing where comparable systems exist based on a client-server approach. It is hoped that this work contributes to the further adoption of "Grassroots" distributed computing by bringing the ability to host and manage a distributed computing project to a much wider audience.

description: This study examined the impact of inpatient rehabilitation in acute care hospitals on hospital readmission in patients undergoing lower limb amputation (LLA) due to diabetes mellitus (DM) using propensity score analysis. This retrospective cohort study utilized the JMDC database. Patients who underwent transtibial and transfemoral amputation with DM as the reason for admission or comorbidity were included. Patients were divided into the rehabilitation group (started rehabilitation within 14 days of admission) and the non-rehabilitation group (did not receive rehabilitation within 14 days of admission). The primary outcomes were hospital readmission within 30 and 60 days post-discharge. Overall, 594 patients were analyzed, with 481 receiving inpatient rehabilitation. After inverse probability weighting (IPW) adjustment, the rehabilitation group had a significantly longer hospital stay than the non-rehabilitation group (rehabilitation: 69.1 [53.4], non-rehabilitation: 39.9 [30.4] days, p < 0.01). Following IPW adjustment, rehabilitation was significantly associated with lower readmission within 30 (OR = 0.519, 95% CI = 0.368–0.734, p < 0.01) and 60 days (OR = 0.673, 95% CI = 0.495–0.913, p = 0.011). Early inpatient rehabilitation may be one way to reduce the risk of hospital readmission for patients with LLA due to DM. Many patients undergo lower limb amputations (LLAs) because of diabetes mellitus (DM), and hospital readmission rates for patients with LLA due to DM are high. Early inpatients rehabilitation in acute care hospitals reduced hospital readmission within 30 and 60 days for patients with LLA due to DM. Patients who received inpatient rehabilitation had a significantly longer hospital stay in acute care hospitals than those who did not receive rehabilitation.

description: Aim of this paper is to address the problem of learning Boolean functions from training data with missing values. We present an extension of the BRAIN algorithm, called U-BRAIN (Uncertainty-managing Batch Relevance-based Artificial INtelligence), conceived for learning DNF Boolean formulas from partial truth tables, possibly with uncertain values or missing bits. Such an algorithm is obtained from BRAIN by introducing fuzzy sets in order to manage uncertainty. In the case where no missing bits are present, the algorithm reduces to the original BRAIN.
Reliable Estimation of Heart Surface Motion under Stochastic and Unknown but Bounded Systematic Uncertainties

Year: 2010

description: A reliable estimation of heart surface motion is an important prerequisite for the synchronization of surgical instruments in robotic beating heart surgery. In general, only an imprecise description of the heart dynamics and measurement systems is available. This means that the estimation of heart motion is corrupted by stochastic and systematic uncertainties. Without consideration of these uncertainties, the obtained results will be inaccurate and a safe robotic operation cannot be guaranteed. Until now, existing approaches for estimating the motion of the heart surface are either deterministic or treat only stochastic uncertainties. The proposed method extends the heart motion estimation to the simultaneous consideration of stochastic and unknown but bounded systematic uncertainties. It computes dynamic bounds in order to provide the surgeon with a guidance by constraining the motion of the surgical instruments and thereby protecting sensitive tissue.

description: The well-known algorithm for summing of divergent series is based on the Borel transformation in combination with the conformal mapping (Le Guillou and Zinn-Justin, 1977). Modification of this algorithm allows to determine a strong coupling asymptotics of the sum of the series through the values of the expansion coefficients. Application of the algorithm to the β-function of ϕ^4 theory leads to the asymptotics β(g)=β_\infty g^αat g\to\infty, where α\approx 1 for space dimensions d=2,3,4. The natural hypothesis arises, that asymptotic behavior is β(g)\sim g for all d. Consideration of the "toy" zero-dimensional model confirms the hypothesis and reveals the origin of this result: it is related with a zero of a certain functional integral. Generalization of this mechanism to the arbitrary space dimensionality leads to the linear asymptotics of β(g) for all d. The same idea can be applied for QED and gives asymptotics β(g)=g, where g is the running fine structure constant. Relation to the "zero charge" problem is discussed.

description: The structure and the magnetic properties of an InGaAs/Fe3Si superlattice in a cylindrical geometry are investigated by electron microscopy techniques, x-ray diffraction and magnetometry. To form a radial superlattice, a pseudomorphic InGaAs/Fe3As bilayer has been released from its substrate self-forming into a rolled-up microtube. Oxide-free interfaces as well as areas of crystalline bonding are observed and an overall lattice mismatch between succeeding layers is determined. The cylindrical symmetry of the final radial superlattice shows a significant effect on the magnetization behavior of the rolled-up layers.
Automated Abundance Analysis of Underwater Video using Artificial Intelligence Techniques
Creators: name: Fearn, RC
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Image processing

description: This thesis discusses research into the various factors associated with the detection, classification and tracking of commercial scallops in underwater video (from a moving camera), for the purpose of computing abundance analysis statistics. Such statistics are sought by the Tasmanian Aquaculture and Fisheries Institute (TAFI) to support the sustainable management of Tasmanian commercial scallop fisheries. The use of video is preferable in terms of environmental impact to a traditional approach such as dredging, but the partially buried nature of the scallops makes the task very challenging. The research led to the development of a multi-stage video analysis system using a range of existing artificial intelligence techniques from the fields of computer vision and machine learning. The system comprises five main stages: instance detection, feature extraction, instance classification, motion estimation and temporal instance tracking. This system may be required to analyse many hours of video footage. Therefore we have explored many different computer-vision-related techniques and performed numerous comparisons on these techniques in an effort to maximise system throughput without compromising the overall accuracy achieved. This includes using the University of Southern California’s iLab Neuromorphic Vision C++ Toolkit (iNVT) [iLab, 2010], during the initial stages of processing, to quickly reduce the overall search space of our system down to the analysis of conspicuous or salient regions within the footage. In addition to this we also investigated solutions that allow our system to skip frames during analysis. This decreases the overall processing time as fewer frames are presented to the system, but can also adversely affect the accuracy of motion estimation. To overcome this we then use a simple and efficient outlier detection method capable of smoothing inconsistencies within the data prior to predicting instance locations in future frames. The performance of each stage of our system has a direct impact on the performance of the remaining stages within the system. However of particular interest is the final stage which uses clustering to achieve temporal instance tracking, as it has become evident that this stage is not only capable of tracking instances through time but is also capable of performing a second round of classification based on cluster density that plays a vital role in the elimination of false positive instances introduced in earlier stages. As a result our system performs well, being robust enough to overcome significant inconsistencies within the existing video footage provided by TAFI.
A Wearable System for the Wireless Experience of Extended Range Telepresence

description: Extended range telepresence aims at enabling a user to experience virtual or remote environments, taking his own body movements as an input to define walking speed and viewing direction. Therefore, localization and tracking of the users pose (position and orientation) is necessary to perform a body-centered scene rendering. Visual and acoustic feedback is provided to the user by a head mounted display (HMD). To allow for free movement within the user environment, the tracking system is supposed to be user-wearable and entirely wireless. Consequently, a lightweight design is presented fea- turing small dimensions to fit into a conventional 13"laptop backpack, which satisfies the above stated demands for highly immersive extended range telepresence scenarios. Dedicated embedded hardware combined with off-the-shelf components is employed to form a robust, low-cost telepresence system that can be easily installed in any living room.

description: Observational indications combined with analyses of analogue and emergent gravity in condensed matter systems support the possibility that there might be two distinct energy scales related to quantum gravity: the scale that sets the onset of quantum gravitational effects $E_B$ (related to the Planck scale) and the much higher scale $E_L$ signalling the breaking of Lorentz symmetry. We suggest a natural interpretation for these two scales: $E_L$ is the energy scale below which a special relativistic spacetime emerges, $E_B$ is the scale below which this spacetime geometry becomes curved. This implies that the first `quantum' gravitational effect around $E_B$ could simply be that gravity is progressively switched off, leaving an effective Minkowski quantum field theory up to much higher energies of the order of $E_L$. This scenario may have important consequences for gravitational collapse, inasmuch as it opens up new possibilities for the final state of stellar collapse other than an evaporating black hole.

Long-time saturation of the Loschmidt echo in quantum chaotic billiards

description: The Loschmidt echo (LE) (or fidelity) quantifies the sensitivity of the time evolution of a quantum system with respect to a perturbation of the Hamiltonian. In a typical chaotic system the LE has been previously argued to exhibit a long-time saturation at a value inversely proportional to the effective size of the Hilbert space of the system. However, until now no quantitative results have been known and, in particular, no explicit expression for the proportionality constant has been proposed. In this paper we perform a quantitative analysis of the phenomenon of the LE saturation and provide the analytical expression for its long-time saturation value for a semiclassical particle in a two-dimensional chaotic billiard. We further perform extensive (fully quantum mechanical) numerical calculations of the LE saturation value and find the numerical results to support the semiclassical theory.

Sir James Croft, 1518-1590
Creators: name: Wright, Patrick Dermot
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is biographical in form, and follows a chronological development. James Croft's life illustrates many of the problems of an ambitious man of the period, and spans more than seventy years and four reigns. His early career was as a soldier, and this aspect, as well as a survey of his family background, has been dealt with in Chapter One. In 1551, Croft served in Ireland, originally as leader of an expeditionary force, but later as Lord Deputy, the first post in his career of major importance. The accession of Mary to the throne in 1553 prompted Croft to take part in the poorly-planned and ill-fated Wyatt's Rebellion, which led to Croft's imprisonment and subsequent loss of revenue. Following Elizabeth's accession in 1558, Croft was made Governor of the town of Berwick, on the Scottish border, and took a major part in the action against the French troops at Leith. His eventual disgrace led to his exile from Court until 1570, in which year he was created Comptroller of the Queen's Household, a position he held for the remainder of his life. Chapter Five deals not only with his duties as Comptroller, but contains an examination of Croft's growing importance in his home county of Herefordshire, and shows his increasing influence and range of contacts at Court. Croft's final appearance two years before his death, was as a commissioner to negotiate with the Spanish in the Low Countries in early 1588. The final chapter of this thesis attempts to examine the significance of Croft as typical of a section of Tudor society, and deals with some of the problems raised by modern historians of the period. Investigation has necessarily been limited by the shortage of records available for research. In the absence of any collection of family papers, the principal sources have been various collections of state papers and letters, contemporary annals and diaries, and such sources as the Acts of the Privy Council and parliamentary records. In spite of the difficulties involved, a surprising amount of information concerning James Croft is extant. A reasonably clear outline of his activities can be seen, and it has been possible to place him in the larger context of sixteenth century society.

description: Anomalously large thermopower of mesoscopic normal-metal/superconductor interferometers has been investigated by Chandrasekhar et al. It was shown that, depending on the geometry of the interferometer, the thermopower is either symmetric or antisymmetric periodic function of the magnetic flux. We develop a detailed theory of the observed thermoelectric phenomena in the framework of the non-equilibrium quasiclassical approach. In particular we provide, for the first time, a possible explanation of the symmetric thermopower oscillations. This effect is attributed to the electron-hole symmetry violation that originates in the steady-state charge imbalance between different arms of the interferometer. Our theory can be tested by an additional control over the charge imbalance in a modified setup geometry. We also predict a sign reversal behavior of the thermopower with increasing temperature that is consistent with the experiments by Parsons et al.

description: The successful protection of sites of high conservation value from the unintentional introduction of species necessitates an understanding of the drivers and impediments to action, and the manner in which research, policy development and praxis interface to constitute an appropriate level of protection - in theory and in practice. Factors bearing on how the quarantine protection of such sites is constituted are usefully explored in relation to islands - on account of the heightened planning considerations associated with their geographies and destination appeal, and their relatively small size, notionally defendable edges and oft-cited vulnerability and importance as refuges for rare and endangered species. Eight Australian Islands designated IUCN Category 1a Protected Areas (Strict Nature Reserves) were selected as case studies using a mixed, purposeful sampling strategy that deferred to each case's likely intrinsic merit in illustrating a diversity of protection issues, and in providing balance and variety of information. Insights into biosecurity praxis were elicited by conducting semi-structured interviews with policy makers, land managers and the proponents of island activities; reviewing the grey literature of stakeholder agencies; and observing quarantine management practices. Factors found to impact upon praxis included perspectives held about the activities providing for introductions and the extent to which these pathways can and need to be managed, how non-indigenous species issues are articulated and scoped, the sometimes default and problematic reliance placed on quarantine arrangements constituted at the national level, the degree to which land management agencies and land users are compelled to act and perspectives on the efficacy of past protection efforts.

We illustrate these issues through two case studies of inflationary scenarios in string theory: warped D-brane inflation and axion monodromy inflation. Finally, we indicate how future observations can test scenarios of inflation in string theory.

description: The zero-error capacity of a classical channel is expressed in terms of the independence number of some graph and its tensor powers. This quantity is hard to compute even for small graphs such as the cycle of length seven, so upper bounds such as the Lovasz theta function play an important role in zero-error communication. In this paper, we show that the Lovasz theta function is an upper bound on the zero-error capacity even in the presence of entanglement between the sender and receiver.

Here the OC is explored in contrast to the results of the DC (Xiong et al., 2007). Both the slow MC1 and fast MC2 are consequently injected from the different heliospheric latitudes to form a compound stream during the interplanetary propagation. The MC1 and MC2 undergo contrary deflections during the process of oblique collision. Their deflection angles of $|δθ_1|$ and $|δθ_2|$ continuously increase until both MC-driven shock fronts are merged into a stronger compound one. The $|δθ_1|$, $|δθ_2|$, and total deflection angle $Δθ$ ($Δθ= |δθ_1| + |δθ_2|$) reach their corresponding maxima when the initial eruptions of both MCs are at an appropriate angular difference. Moreover, with the increase of MC2's initial speed, the OC becomes more intense, and the enhancement of $δθ_1$ is much more sensitive to $δθ_2$. The $|δθ_1|$ is generally far less than the $|δθ_2|$, and the unusual case of $|δθ_1|\simeq|δθ_2|$ only occurs for an extremely violent OC. But because of the elasticity of the MC body to buffer the collision, this deflection would gradually approach an asymptotic degree. Therefore, the deflection due to the OC should be considered for the evolution and ensuing geoeffectiveness of interplanetary interaction among successive coronal mass ejections (CMEs).

Wide-Area Haptic Guidance: Taking the User by the Hand
Creators: name: Pérez Arias, Antonia

Year: 2010

description: In this paper, we present a novel use of haptic information in extended range telepresence, the wide-area haptic guidance. It consists of force and position signals applied to the user's hand in order to improve safety, accuracy, and speed in some telepresent tasks. Wide-area haptic guidance assists the user in reaching a desired position in a remote environment of arbitrary size without degrading the feeling of presence. Several methods for haptic guidance are analyzed. With active haptic guidance, the user is guided by superimposed forces that pull him into the desired direction of motion, whereas under passive haptic guidance, the movement of the user is lightened in the preferred direction and constrained in the other directions. By using closed-loop haptic guidance instead of open-loop haptic guidance, not only is the user guided to his target but also the deviation from the desired target path is reduced. The proposed guidance methods were tested with a haptic interface specifically designed for extended range telepresence.

description: If the lightest CP-even Higgs boson in the MSSM is discovered at the LHC, two measurements could be made simultaneously: the Higgs mass m_h and the event rate Bs(gg -> h -> gamma gamma). We study to what extent the combination of these two measurements would allow us to extract parameters in the stop mass matrix, including the off-diagonal mixing term, with a focus on the MSSM golden region where the stops are light and the mixing is large. Even though both the production cross-section and the decay amplitude are not sensitive to supersymmetric parameters outside of the stop sector, the branching ratio depends on the total decay width, which is dominated by the Higgs decay to b quarks and sensitive to both the pseudo-scalar mass m_A and the supersymmetric Higgs mass μ. In the end we find m_A is an important input in extracting the stop mass parameters, while a fair estimate of the off-diagonal mixing term could be obtained without prior knowledge of μ.

A linguistic study of Pʻi pa chi rhymes
Creators: name: Na, Zongxun
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study was to study the rhymes in P'i Pa Chi, a drama from South China in the Yuan Dynasty. To achieve this purpose the rhyme words of P'i Pa Chi were gathered and divided into rhyming categories. These were compared with earlier and contemporary phonological works such as rhyme tables, rhyme dictionaries etc. and some particular problems were studied. P'i Pa Chi's rhyme categories, of course, cannot provide every single detail of real speech, but they do indicate certain differences as compared with contemporary Northern Drama which are important clues to an understanding of the phonological phenomena in Southern China in the Yuan Dynasty.
The Impact of Culture on ERP Implementation: SAP in China

Subjects: Information systems not elsewhere classified

description: The primary purpose of this research was to study the impact of culture on the implementation of a Western-developed ERP system (SAP) in an Asian environment from the local Chinese informant’s perspective. Unlike the majority of IS cultural research into ERP implementation, this study used a qualitative approach. Unstructured interviews were used on two occasions to collect data from informants during the implementation with a focus on their personal perceptions and interactions. This approach was adopted to allow informants to freely express their experiences and opinions in relations to the implementation. This implies that the researcher did not direct the interviews with any predetermined questions but rather allow the informants to direct the focus base on what they saw as important. Data analysis was based on the Seven Steps framework from Colaizzi (1978). The overall result of this research was that culture had a positive influence on the implementation of a Western-developed ERP system (SAP) in China. The findings in the case study showed that while the implementation of an ERP system had introduced new elements into their work practices and created new challenges for the informants, they did not see them in terms of cultural differences and mismatches. Instead, they accepted them as changes that must be accommodated. They relied on their creativity and innovation to find a better way to make the ERP system more compatible to their work practices. This is important because contrary to the common view, cultural misalignment did not cause rejection of the SAP system, and further a non-Western culture did not necessarily make implementation of Western- developed ERP systems more difficult to implement in an Asian environment. Furthermore, the findings in the case study showed that the Chinese cultural values of Guanxi are important in the management of uncertainties created from environmental factors and deficiencies in the SAP system. The research described in this thesis confirmed the usefulness of the National Cultural Dimensions (Hofstede, 1980) and Situated Culture Theory (Weisinger & Salipante, 2000) for obtaining meaningful insights that drew together the influences of environmental factors and Chinese culture, and how the informants dealt with the SAP implementation. The outcome of this research has provided new insights into an appreciation of different cultural values and an understanding on how informants intuitively applied them as problem-solving tools. In addition based on this research, suggestions have been made for future research with a focus on how culture could be taken into account to support the implementation of new technologies.

description: The Jaynes-Cummings-Hubbard (JCH) system describes a network of single-mode photonic cavities connected via evanescent coupling. Each cavity contains a single two level system which can be tuned in resonance with the cavity. Here we explore the behavior of single excitations (where an excitation can be either photonic or atomic) in the linear JCH system, which describes a coupled cavity waveguide. We use direct, analytic diagonalization of the Hamiltonian to study cases where inter-cavity coupling is either uniform or varies parabolically along the chain. Both excitations located in a single cavity, as well as one excitation as a Gaussian pulse spread over many cavities, are investigated as initial states. We predict unusual behavior of this system in the time domain, including slower than expected propagation of the excitation, and also splitting of the excitation into two distinct pulses, which travel at distinct speeds. In certain limits, we show that the JCH system mimics two Heisenberg spin chains.

description: Sebecid notosuchians are the only terrestrial crocodyliforms to survive the Cretaceous–Paleogene extinction, 66 Ma, which eliminated large-bodied species (~>5 kg) in terrestrial ecosystems. Early sebecid evolution is unclear due to the scarcity of remains from both sides of the boundary. We present the stratigraphically earliest post-extinction notosuchian record, from the lower Paleocene Salamanca Formation of Patagonia. Tewkensuchus salamanquensis n. gen. n. sp. has unique features, including a skull roof with elevated lateral margins, and an accessory peg and socket articulation between the postorbital and posterior palpebral. Our phylogenetic analysis allies Tewkensuchus with a clade of predatorial crocodyliforms from the Eocene of Europe (and possibly of Africa, as Eremosuchus may belong to this clade). This clade forms the sister taxon of South American sebecids. We name Sebecoidea for this more inclusive clade of Eurogondwanan notosuchians and suggest that its spatial distribution reflects earlier diversification and dispersal events, which are only partially known. We estimate a body mass of ~300 kg for Tewkensuchus, one of the largest known notosuchians. Phylogenetic optimization of notosuchian body size change reconstructs a Cretaceous–Paleogene boundary-crossing sebecoidean lineage with an estimated mass between 332–443 kg. This provides the first support for survival of a large-bodied terrestrial vertebrate lineage across the K-Pg boundary.
