description: We present a systematic study of twist-3 light-cone distribution amplitudes of $K^*$ and $ϕ$ mesons in QCD. The structure of SU(3)-breaking corrections is studied in detail. Non-perturbative input parameters are estimated from QCD sum rules. As a by-product, we update the parameters describing the twist-3 distribution amplitudes of the $ρ$ meson. We also review and update predictions for the twist-2 distribution amplitudes of $ρ$, $K^*$ and $ϕ$.

description: Industrial big data is an important part of big data family, which has important application value for industrial production scheduling, risk perception, state identification, safety monitoring and quality control, etc. Due to the particularity of the industrial field, some concepts in the existing big data research field are unable to reflect accurately the characteristics of industrial big data, such as what is industrial big data, how to measure industrial big data, how to apply industrial big data, and so on. In order to overcome the limitation that the existing definition of big data is not suitable for industrial big data, this paper intuitively proposes the concept of big data cloud and the 3M (Multi-source, Multi-dimension, Multi-span in time) definition of cloud-based big data. Based on big data cloud and 3M definition, three typical paradigms of industrial big data applications are built, including the fusion calculation paradigm, the model correction paradigm and the information compensation paradigm. These results are helpful for grasping systematically the methods and approaches of industrial big data applications.

Effects of metallicity on mode switching in Cepheids
Creators: name: Fadeyev, Yu. A.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The mode switching in Cepheids is studied using the methods of the nonlinear theory of stellar pulsation, depending on the main sequence mass $M_0$ and the abundance of elements heavier than helium $Z$. The grid of evolutionary and hydrodynamic models of core--helium burning Cepheids is represented by 30 evolutionary sequences of stars with initial masses $5.7M_\odot\le M_0\le 7.2M_\odot$ and $Z=0.014$, 0.018, 0.022. For considered values of $Z$ the periods of the fundamental mode and the first overtone at the oscillation mode switching are shown to depend on the mean density of the stellar matter. The upper limit of the period of the first overtone decreases witn increasing $Z$ from $\approx 6.9$ day for $Z=0.014$ to $\approx 4.1$ day for $Z=0.022$. The theoretical period--radius relation is independent of $Z$ and agrees well (within 2.5\%) with recent measurements of Cepheid radii based on the Baade--Wesselink method. The fundamental parameters of the short--period Cepheid CG Cas were derived with application of observational estimates of the period and the rate of period change. This star is shown to be the first--overtone pulsator.

Is LaO$_{1-x}$F$_x$FeAs an electron-phonon superconductor ?

description: In this paper we calculate the electron-phonon coupling of the newly-discovered superconductor LaO$_{1-x}$F$_x$FeAs from first-principles, using Density Functional Perturbation Theory. For pure LaOFeAs, the calculated electron-phonon coupling constant $λ=0.21$ and logarithmic-averaged frequency $ω_{ln}=206 K$, give a maximum $T_c$ of 0.8 K, using the standard Migdal-Eliashberg theory. For the $F-$doped compounds, we predict even smaller coupling constants, due to the strong suppression of the electronic Density of States at the Fermi level. To reproduce the experimental $T_c=26 K$, a 5-6 times larger coupling constant would be needed. Our results indicate that electron-phonon coupling is not sufficient to explain superconductivity in the newly-discovered LaO$_{1-x}$F$_x$FeAs superconductor, probably due to the importance of strong correlation effects.

description: Topological insulators have emerged as an important material class for efficient spin-charge interconversion. Most topological insulators considered to date are binary or ternary compounds, with the exception of $α$-Sn. Here we report a comprehensive characterization of the growth, magnetotransport properties, and current-induced spin-orbit torques of $α$-Sn and $β$-Sn-based ferromagnetic heterostructures. We show that $α$-Sn grown with a Bi surfactant on CdTe(001) promotes large spin-orbit torques in a ferromagnetic FeCo layer at room temperature, comparable to Pt, whereas $α$-Sn grown without Bi surfactant and the non-topological phase, $β$-Sn, induce lower torques. The dampinglike and fieldlike spin-orbit torque efficiency in $α$-Sn with Bi are 0.12 and 0.18, respectively. Further, we show that $α$-Sn grown with and without Bi presents a spin Hall-like magnetoresistance comparable to that found in heavy metal/ferromagnet bilayers. Our work demonstrates direct and efficient charge-to-spin conversion in $α$-Sn ferromagnetic heterostructures, showing that $α$-Sn is a promising material for current-induced magnetization control in spintronic devices.

description: The present diploma thesis formulates and implements two algorithms for the determination of the greatest common divisor of polynomial matrices with the same number of columns. The first of the two methods is based on the Euclidean algorithm for the calculation of the greatest common divisor of integer numbers, suitably adapted for application on polynomial matrices, by utilizing consecutive polynomial matrix division. The second method is presented in [Wolovich, 1974; Vardulakis, 1991; Michailidis, 2015] and utilizes elementary matrix operations and Euclidean division of polynomials for the determination of the Smith form of a polynomial matrix, a process, in the course of which the greatest common left or right divisor is determined, depending on whether the original matrices have the same number of rows or columns respectively. The first chapter briefly describes the theoretical background, elements of which are used later on to develop the basic theory. The second and third chapters expose the two aforementioned methods in more detail, for the calculation of the greatest common right divisor of two polynomial matrices. The standardized algorithmic processes are described in the chapters, along with corresponding examples to clarify the process. Finally, the fourth chapter cites the code for the implementation of the two algorithms in the MATLAB® development environment.

description: The ongoing trend of moving data and computation to the cloud is met with concerns regarding privacy and protection of intellectual property. Cloud Service Providers (CSP) must be fully trusted to not tamper with or disclose processed data, hampering adoption of cloud services for many sensitive or critical applications. As a result, CSPs and CPU manufacturers are rushing to find solutions for secure outsourced computation in the Cloud. While enclaves, like Intel SGX, are strongly limited in terms of throughput and size, AMD's Secure Encrypted Virtualization (SEV) offers hardware support for transparently protecting code and data of entire VMs, thus removing the performance, memory and software adaption barriers of enclaves. Through attestation of boot code integrity and means for securely transferring secrets into an encrypted VM, CSPs are effectively removed from the list of trusted entities. There have been several attacks on the security of SEV, by abusing I/O channels to encrypt and decrypt data, or by moving encrypted code blocks at runtime. Yet, none of these attacks have targeted the attestation protocol, the core of the secure computing environment created by SEV. We show that the current attestation mechanism of Zen 1 and Zen 2 architectures has a significant flaw, allowing us to manipulate the loaded code without affecting the attestation outcome. An attacker may abuse this weakness to inject arbitrary code at startup -- and thus take control over the entire VM execution, without any indication to the VM's owner. Our attack primitives allow the attacker to do extensive modifications to the bootloader and the operating system, like injecting spy code or extracting secret data. We present a full end-to-end attack, from the initial exploit to leaking the key of the encrypted disk image during boot, giving the attacker unthrottled access to all of the VM's persistent data.

description: Given an arbitrary state $ρ$ and some figure of merit ${\cal E}(ρ)$, it is usually a hard problem to determine the value of ${\cal E}(ρ^{\otimes N})$. One noticeable exception is the case of additive measures, for which we simply have ${\cal E}(ρ^{\otimes N}) = Ne$, with $e\equiv {\cal E}(ρ)$. In this work we study measures that can be described by ${\cal E}(ρ^{\otimes N}) =E(e;N) \ne Ne$, that is, measures for which the amount of resources of $N$ copies is still determined by the single real variable $e$, but in a nonlinear way. If, in addition, the measures are analytic around $e=0$, recurrence relations can be found for the Maclaurin coefficients of $E$ for larger $N$. As an example, we show that the $\ell_1$-norm of coherence is a nontrivial case of such a behavior.

description: We propose to measure azimuthal correlations of heavy-flavor hadrons to address the status of thermalization at the partonic stage of light quarks and gluons in high-energy nuclear collisions. In particular, we show that hadronic interactions at the late stage cannot significantly disturb the initial back-to-back azimuthal correlations of DDbar pairs. Thus, a decrease or the complete absence of these initial correlations does indicate frequent interactions of heavy-flavor quarks and also light partons in the partonic stage, which are essential for the early thermalization of light partons.

description: Σκοπός της διπλωματικής εργασίας ήταν η ανασκόπηση της υπάρχουσας βιβλιογραφίας για τον καθορισμό του ρόλου της μαγνητικής τομογραφίας καρδιάς στην απεικόνιση της δεξιάς καρδιάς. Οι ανατομικές και λειτουργικές ιδιαιτερότητες της δεξιάς κοιλίας καθιστούν την απεικόνισή της δύσκολη με τις συμβατικές απεικονιστικές μεθόδους. Η μαγνητική τομογραφία καρδιάς (CMR), απαλλαγμένη από γεωμετρικές υποθέσεις και την υποκειμενικότητα του παρατηρητή, αποτελεί εξαιρετική μέθοδο για τον υπολογισμό όγκων και του κλάσματος εξώθησης, της δεξιάς καρδιακής μάζας, της αιματικής ροής διαμέσου των καρδιακών βαλβίδων αλλά και για τον ιστικό χαρακτηρισμό του μυοκαρδίου. Με αυτόν τον τρόπο, η CMR παίζει πολύ σημαντικό ρόλο στη διάγνωση, την εκτίμηση της πρόγνωσης και την επιλογή της κατάλληλης θεραπευτικής αντιμετώπισης παθήσεων που προσβάλλουν τη δεξιά κοιλία, όπως η ισχαιμική μυοκαρδιοπάθεια, η αρρυθμιογόνος δυσπλασία της δεξιάς κοιλίας, συγγενείς καρδιοπάθειες και η πνευμονική αρτηριακή υπέρταση. Παρά τα μειονεκτήματά της (υψηλό κόστος, ανάγκη εξειδικευμένων τεχνολογικών μέσων και καταρτισμένου προσωπικού, περιορισμοί στη χρήση της), ολοένα και περισσότερες μελέτες ενισχύουν τη σημασία της CMR σε αυτές τις νόσους και τείνουν να την αναδείξουν σε εξέταση ρουτίνας, επί παρουσίας κλινικών ενδείξεων. Τέλος, η ανάπτυξη νέων ακολουθιών ( T1,T2 mapping) και η εξέλιξη υβριδικών μεθόδων (π.χ PET MRI) αναμένεται να συμβάλλουν στην καλύτερη κατανόηση της παθοφυσιολογίας αυτών των παθήσεων και στην έγκαιρη διάγνωσή τους.
description: The aim of the present study was to review current literature in order to determine the role of Cardiac Magnetic Resonance (CMR) in imaging of the right heart. The anatomical and functional characteristics of the right ventricle make her difficult to image with the traditional methods. CMR, free of geometrical assumptions and the observer’s subjectivity, is an excellent method for the calculation of volumes, ejection fraction, right cardiac mass, blood flow through cardiac valves as well as for myocardial tissue characterization. Therefore, CMR plays a very important role in diagnosis, estimation of prognosis and treatment of diseases that affect the right ventricle, such as right ischaemic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, congenital heart disease and pulmonary arterial hypertension. Despite its’ disadvantages (cost, need for sophisticated equipment and specialized personnel, limitations), many studies highlight the importance of CMR in these cases and tend to establish it as a routine examination method, when there are sufficient clinical evidence. Finally, the development of new sequences (T1, T2 mapping) and the evolution of hybrid techniques (PET MRI) are expected to contribute to the better understanding of the underlying pathophysiology and the early diagnosis of these diseases.
title: Quantification of the effects of ocean acidification on benthic foraminifera
Creators: name: Guamán Guevara, Luis Fabricio
Publisher: name: University of St Andrews
Year: 2019

description: The global ocean has experienced an alteration of its seawater chemistry due to the continuing uptake of anthropogenic carbon dioxide (CO₂) from the atmosphere. This ongoing process called Ocean acidiﬁcation (OA) has reduced seawater pH levels, carbonate ion concentrations (CO₃⁻²) and carbonate saturation state (Ω) with implications for the diversity and functioning of marine life, particularly for marine calcifiers such as foraminifera. The vulnerability of this ubiquitous calcifying group to future high 𝘱CO₂ /low pH scenarios has been assessed naturally and experimentally in the last decades. However, little is known about how benthic foraminifera from coastal environments such as intertidal environments will respond to the effects of OA projected by the end of the century. This research aimed to quantify the effects of OA on a series of biological parameters measured on the benthic foraminifera 𝘌𝘭𝘱𝘩𝘪𝘥𝘪𝘶𝘮 𝘸𝘪𝘭𝘭𝘪𝘢𝘮𝘴𝘰𝘯𝘪 and 𝘏𝘢𝘺𝘯𝘦𝘴𝘪𝘯𝘢 𝘨𝘦𝘳𝘮𝘢𝘯𝘪𝘤𝘢 through a laboratory-based experimental approach where future scenarios of a high CO₂ atmosphere and low seawater pH were explored. Experimental evidence revealed that survival rates, test weight and size-normalized weight (SNW) of 𝘌. 𝘸𝘪𝘭𝘭𝘪𝘢𝘮𝘴𝘰𝘯𝘪 were negatively affected by OA. Whereas 𝘏. 𝘨𝘦𝘳𝘮𝘢𝘯𝘪𝘤𝘢 was positively affected (i.e. enhanced growth rates) showing a species-specific response to OA at 13°C. However, the combined effect of OA and temperature (15°C) reduced survival and growth rates for 𝘌𝘭𝘱𝘩𝘪𝘥𝘪𝘶𝘮 𝘸𝘪𝘭𝘭𝘪𝘢𝘮𝘴𝘰𝘯𝘪 and 𝘏𝘢𝘺𝘯𝘦𝘴𝘪𝘯𝘢 𝘨𝘦𝘳𝘮𝘢𝘯𝘪𝘤𝘢. Test morphology (i.e. test surface and feeding ornamentation) of live 𝘌. 𝘸𝘪𝘭𝘭𝘪𝘢𝘮𝘴𝘰𝘯𝘪 and 𝘏. 𝘨𝘦𝘳𝘮𝘢𝘯𝘪𝘤𝘢 were severely affected after 6 weeks by OA, negatively influencing the uptake of 13C-labelled diatoms of 𝘕𝘢𝘷𝘪𝘤𝘶𝘭𝘢 𝘴𝘱., notably for 𝘌. 𝘸𝘪𝘭𝘭𝘪𝘢𝘮𝘴𝘰𝘯𝘪. Test dissolution rates were enhanced by OA and negatively affected foraminiferal morphology of recently dead assemblages with implications for net accumulation and preservation. These results imply that the long-term storage of inorganic carbon and cycling of carbon in coastal benthic ecosystems will be considerably altered by future OA.

description: An intrinsic curvature model is investigated using the canonical Monte Carlo simulations on dynamically triangulated spherical surfaces of size upto N=4842 with two fixed-vertices separated by the distance 2L. We found a first-order transition at finite curvature coefficient α, and moreover that the order of the transition remains unchanged even when L is enlarged such that the surfaces become sufficiently oblong. This is in sharp contrast to the known results of the same model on tethered surfaces, where the transition weakens to a second-order one as L is increased. The phase transition of the model in this paper separates the smooth phase from the crumpled phase. The surfaces become string-like between two point-boundaries in the crumpled phase. On the contrary, we can see a spherical lump on the oblong surfaces in the smooth phase. The string tension was calculated and was found to have a jump at the transition point. The value of σis independent of L in the smooth phase, while it increases with increasing L in the crumpled phase. This behavior of σis consistent with the observed scaling relation σ\sim (2L/N)^ν, where ν\simeq 0 in the smooth phase, and ν=0.93\pm 0.14 in the crumpled phase. We should note that a possibility of a continuous transition is not completely eliminated.

description: Printed Circuit Boards are the foundation for the functioning of any electronic device, and therefore are an essential component for various industries such as automobile, communication, computation, etc. However, one of the challenges faced by the PCB manufacturers in the process of manufacturing of the PCBs is the faulty placement of its components including missing components. In the present scenario the infrastructure required to ensure adequate quality of the PCB requires a lot of time and effort. The authors present a novel solution for detecting missing components and classifying them in a resourceful manner. The presented algorithm focuses on pixel theory and object detection, which has been used in combination to optimize the results from the given dataset.

Η εύρεση του skyline σε μεγάλες βάσεις δεδομένων εικόνων, απαιτεί αποδοτικές δομές δεικτοδότησης. Τέτοιες δομές υλοποιούνται με την βοήθεια αλγορίθμων κατακερματισμού. Η εργασία παρουσιάζει αναλυτικά τέσσερις αλγορίθμους κατακερματισμού και δυο αλγόριθμου εύρεσης του skyline. Αξιολογεί πειραματικά την απόδοσή τους ως αναφορά τον χρόνο εκτέλεσής τους αλλά και ως αναφορά το περιεχόμενο του τελικού skyline. Τα αποτελέσματα της σύγκρισης δείξαν ότι γρηγορότερος από τους δυο αλγόριθμους είναι ο Branch and Bound Skyline. Τέλος ένα σημαντικό συμπέρασμα της εργασίας είναι η παρατήρηση ότι οι εικόνες στο τελικό skyline είναι πολύ διαφορετικές πράγμα που μπορεί να χρησιμοποιηθεί ως βάση για μια διαδικασία ομαδοποίησης των εικόνων.
description: The aim of the present thesis is to study and compare within an experimental framework various algorithms used to find items that belong to the skyline in large image databases. In order to find the skyline in such big database one must use efficient indexing structures. Hashing algorithms can be used to achieve this kind of indexing. In the thesis there are presented in detail four hashing algorithms used for indexing and two algorithms used for finding the skyline in a dataset. An evaluation of the results is presented regarding the performance and the content of the final skyline. The results have shown that “Branch and Bound Skyline” is faster in most cases. Finally, the examination of the items in the skyline have shown that items where very different visually. This conclusion is important and can be used as a base for clustering a dataset into groups.

description: We consider multiclass feedforward queueing networks with first in first out and priority service disciplines at the nodes, and class dependent deterministic routing between nodes. The random behavior of the network is constructed from cumulative arrival and service time processes which are assumed to satisfy an appropriate sample path large deviation principle. We establish logarithmic asymptotics of large deviations for waiting time, idle time, queue length, departure and sojourn-time processes in critical loading. This transfers similar results from Puhalskii about single class queueing networks with feedback to multiclass feedforward queueing networks, and complements diffusion approximation results from Peterson. An example with renewal inter arrival and service time processes yields the rate function of a reflected Brownian motion. The model directly captures stationary situations.

Neighborhood self management :a study of the role of local communities in the revitalization of metropolitan areas
Creators: name: Ragetli, Rene Francois
Publisher: name: University of British Columbia
Year: 2009

description: Traditionally observers of the urban scene have held that by unilaterally shifting the balance between central and local control over urban management, conditions within cities could be improved. More recently a theoretical synthesis has been advanced which advocates the decentralization of some urban functions to the neighborhood level and the centralization of others to a metropolitan wide authority. Adherents of this latter position hold that healthy cities operate best on the principle of a “federation of neighborhoods”. Following a review of the construction of modern society, this thesis considers the theoretical benefits of dividing responsibility for four categories of urban functions between local and central authorities. The ideal theoretical division of various environmental, economic, social and political functions has subsequently been tested against an implemented form of neighborhood self management in Jerusalem. The results of this comparison confirm that properly constituted neighborhood authorities can indeed deliver human services more effectively and with considerable financial savings. It has also become apparent that social cohesion is enhanced by recognizing and legitimizing local communities. The Jerusalem experience further reveals that a strong metropolitan wide authority is crucial in securing the judicious use of natural resources and preventing environmental degradation, thereby ensuring long-term economic well being. The considered balancing of urban functions between central and local control would benefit metropolitan areas worldwide, particularly those considering a comprehensive revitalization.

description: The effectiveness of the machine learning methods for real-world tasks depends on the proper structure of the modeling pipeline. The proposed approach is aimed to automate the design of composite machine learning pipelines, which is equivalent to computation workflows that consist of models and data operations. The approach combines key ideas of both automated machine learning and workflow management systems. It designs the pipelines with a customizable graph-based structure, analyzes the obtained results, and reproduces them. The evolutionary approach is used for the flexible identification of pipeline structure. The additional algorithms for sensitivity analysis, atomization, and hyperparameter tuning are implemented to improve the effectiveness of the approach. Also, the software implementation on this approach is presented as an open-source framework. The set of experiments is conducted for the different datasets and tasks (classification, regression, time series forecasting). The obtained results confirm the correctness and effectiveness of the proposed approach in the comparison with the state-of-the-art competitors and baseline solutions.
Constraining white-dwarf kicks in globular clusters : III. Cluster Heating
Creators: name: Heyl, Jeremy S.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Recent observations of white dwarfs in globular clusters indicate that these stars may get a velocity kick during their time as giants. This velocity kick could originate naturally if the mass loss while on the asymptotic giant branch is slightly asymmetric. The kicks may be large enough to dramatically change the radial distribution of young white dwarfs, giving them larger energies than other stars in the cluster. As these energetic white dwarfs travel through the cluster they can impart their excess energy on the other stars in the cluster. This new heat source for globular clusters is expected to be largest during the clusters' youth.

description: We present a new preliminary measurement of the inclusive jet cross section in pp-bar collisions based on a integrated luminosity of about 0.8 fb-1. The data were acquired using the D0 detector between 2002 and 2005. Jets are reconstructed using an iterative cone algorithm with radius R_cone = 0.7. The inclusive jet cross section is presented as a function of transverse jet momentum and rapidity. Predictions from perturbative QCD in next-to-leading order, plus threshold corrections in 2-loop accuracy describe the shape in the transverse jet momentum.

description: This study presents the implementation of an all-optical binary logic half adder by employing triple core photonic crystal fiber (TPCF). The noteworthy feature of the present investigation is that an identical set of TPCF schemes, which demonstrated all-optical logic functions in our previous report has revealed the ability to demonstrate the successful half adder operation. The control signal (CS) power defining the extinction ratios of the output ports for the considered symmetric planar and triangular TPCFs are evaluated through numerical algorithm. Through suitable CS power and input combinations, the logic outputs are generated from extinction ratios to demonstrate the half adder operation. The results obtained display the significant influence of the input conditions on the delivery of half adder operation for different TPCF schemes considered. Furthermore, chloroform filled TPCF structures demonstrated the efficient low power half adder operation with significant figure of merit, compared to that of the silica counterpart.

description: Η παρούσα εργασία σκοπό έχει να θέσει ορισμένα ερωτήματα ως προς τη σχέση των γαλλόφωνων κόμικς με θέμα τους κουρσάρους και την αληθινή ιστορία του γαλλικού κούρσου και του αντίκτυπου του στη σύγχρονη γαλλική κοινωνία. Σε πρώτη φάση τονίζονται οι ριζικές νομικές και τεχνικές διαφορές μεταξύ πειρατών και κουρσάρων. Ακολούθως, ανιχνεύονται οι μεσαιωνικές ρίζες, η νομική και ιστορική εξέλιξη του ευρωπαϊκού φαινομένου που έμεινε γνωστό ως «κούρσο». Το πρώτο μέρος της εργασίας ολοκληρώνεται με την ιστορική ανασκόπηση του γαλλικού κούρσου, μεταξύ 1688-1815 (Β´ Εκατονταετής Πόλεμος) και των ιδιαιτεροτήτων του. Το δεύτερο μέρος ξεκινά με μια σύντομη εισαγωγή στην ιστορία των γαλλόφωνων «εικονογραφημένων». Κατόπιν, μελετώνται τέσσερεις σειρές γαλλόφωνων κόμικς και τίθενται ερωτήματα σχετικά με την αναπαράσταση της σχέσης κουρσάρων και πολιτικής εξουσίας, την αναπαράσταση των εχθρών των κουρσάρων, την παρουσία των γυναικών και των αλλοεθνών λαών καθώς και τις πιθανές πηγές έμπνευσης των δημιουργών αυτών των κόμικς.
description: The aim of the present thesis is to set some questions about the relation between privateer-themed French-speaking comics and the real history of French privateering and its impact to modern-day French society. In the first place, the radical legal and technical differences between pirates and corsairs are clarified. Then, are described the medieval roots, the legal and historical evolution of the european phenomenon that was to be known as “privateering”. The first part of the thesis is completed by the historical overview of the French privateering, during the “Second Hundred Years War” (1688-1815) and its particularities. The second part starts off with a brief introduction to the history of the French-speaking “illustrés”. After that, four French-speaking comic-book series are examined and questions are set, concerning the representation of the privateers’ relations with the political power, the representation of the privateers’ enemies, the presence of the women and the foreign people, as well as the possible inspiration sources of the comic-book creators.

description: We study the dynamics of Bose-Einstein condensed atoms in a 1-D optical lattice potential in a regime where the collective (Josephson) tunneling energy is comparable with the on-site interaction energy, and the number of particles per lattice site is mesoscopically large. By directly imaging the motion of atoms in the lattice, we observe an abrupt suppression of atom transport through the array for a critical ratio of these energies, consistent with quantum fluctuation induced localization. Directly below the onset of localization, the frequency of the observed superfluid transport can be explained by a phonon excitation but deviates substantially from that predicted by the hydrodynamic/Gross-Pitaevskii equations.
