description: We present three-dimensional hybrid simulations of collisionless shocks that propagate parallel to the background magnetic field to study the acceleration of protons that forms a high-energy tail on the distribution. We focus on the initial acceleration of thermal protons and compare it with results from one-dimensional simulations. We find that for both one- and three-dimensional simulations, particles that end up in the high-energy tail of the distribution later in the simulation gained their initial energy right at the shock. This confirms previous results but is the first to demonstrate this using fully three-dimensional fields. The result is not consistent with the "thermal leakage" model. We also show that the gyrocenters of protons in the three-dimensional simulation can drift away from the magnetic field lines on which they started due to the removal of ignorable coordinates that exist in one- and two-dimensional simulations. Our study clarifies the injection problem for diffusive shock acceleration.

description: Cavity QED with cooperativity far greater than unity enables high-fidelity quantum sensing and information processing. The high-cooperativity regime is often reached through the use of short, single-mode resonators. More complicated multimode resonators, such as the near-confocal optical Fabry-Pérot cavity, can provide intracavity atomic imaging in addition to high cooperativity. This capability has recently proved important for exploring quantum many-body physics in the driven-dissipative setting. In this work, we show that a confocal cavity QED microscope can realize cooperativity in excess of 110. This cooperativity is on par with the very best single-mode cavities (which are far shorter) and 21$\times$ greater than single-mode resonators of similar length and mirror radii. The 1.7-$μ$m imaging resolution is naturally identical to the photon-mediated interaction range. We measure these quantities by determining the threshold of cavity superradiance when small, optically tweezed Bose-Einstein condensates are pumped at various intracavity locations. Transmission measurements of an ex situ cavity corroborate these results. We provide a theoretical description that shows how cooperativity enhancement arises from the dispersive coupling to the atoms of many near-degenerate modes.

description: Among men in South Africa, the prevalence of tobacco smoking is as high as 33%. Although smoking is responsible for most lung cancer in South Africa, occupational and environmental exposures contribute greatly to risk. We conducted a tobacco and lung cancer screening needs assessment and administered surveys to adults who smoked >100 cigarettes in their lifetime in Johannesburg (urban) and Kimberley (rural). We compared tobacco use, risk exposure, attitudes toward and knowledge of, and receptivity to cessation and screening, by site. Of 324 smokers, nearly 85% of current smokers had a <30 pack-year history of smoking; 58.7% had tried to stop smoking ≥1 time, and 78.9% wanted to quit. Kimberley smokers more often reported being advised by a healthcare provider to stop smoking (56.5% vs. 37.3%, p=0.001) than smokers in Johannesburg but smokers in Johannesburg were more willing to stop smoking if advised by their doctor (72.9% vs. 41.7%, p<0.001). Findings indicate that tobacco smokers in two geographic areas of South Africa are motivated to stop smoking but receive no healthcare support to do so. Developing high risk criteria for lung cancer screening and creating tobacco cessation infrastructure may reduce tobacco use and decrease lung cancer mortality in South Africa.

description: Nanocomposite coatings are of great interest as barrier coatings since synergy effects between matrix and additive properties can be achieved. This, however, requires favorable additive-matrix interactions to provide a strong interphase (interface region). In this work we elucidate the properties of two environmentally benign nanocomposite coatings based on a waterborne acrylate formulation with additives from renewable sources, i.e. either cellulose nanocrystals, CNC; or, alternatively, cellulose nanofibrils, CNF. We focus on the corrosion protective properties of these coatings and discuss the reason why the nanocomposite with CNC displays favorable corrosion protection properties whereas that with CNF does not. To this end we utilized scanning electron microscopy, water contact angle measurement, Fourier transform infrared spectroscopy and electrochemical impedance spectroscopy techniques to investigate the microstructure, surface wetting, interactions between cellulosic materials and matrix as well as corrosion protective properties of both composite coatings.

description: We show the applicability of the Cartan decomposition of Lie algebras to quantum circuits. This approach can be used to synthesize circuits that can efficiently implement any desired unitary operation. Our method finds explicit quantum circuit representations of the algebraic generators of the relevant Lie algebras allowing the direct implementation of a Cartan decomposition on a quantum computer. The construction is recursive and allows us to expand any circuit down to generators and rotation matrices on individual qubits, where through our recursive algorithm we find that the generators themselves can be expressed with controlled-not (CNOT) and SWAP gates explicitly. Our approach is independent of the standard CNOT implementation and can be easily adapted to other cross-qubit circuit elements. In addition to its versatility, we also achieve near-optimal counts when working with CNOT gates, achieving an asymptotic cnot cost of $\frac{21}{16}4^n$ for $n$ qubits.
pp elastic scattering at ISR and LHC energies

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We describe data on elastic $pp$ scattering at ISR and LHC energies using the analytical representation of the amplitude as the sum of three exponentials equipped with complex phases. In addition, we take into account the Coulomb and Coulomb-nuclear contributions in the entire transfer region and strong "perturbative" contributions in the large transfer region. Refined values of basic scattering characteristics are obtained. Significant changes in the behavior of the amplitude are detected at the transition from ISR to LHC energies. The results obtained indicate a two-layer structure of the colliding protons. In the transition to 13 TeV, a sharp increase in the size of the inner layer and its activity in the scattering is observed. A possible interpretation of this effect is discussed.

Adaptive piecewise polynomial estimation via trend filtering

description: We study trend filtering, a recently proposed tool of Kim et al. [SIAM Rev. 51 (2009) 339-360] for nonparametric regression. The trend filtering estimate is defined as the minimizer of a penalized least squares criterion, in which the penalty term sums the absolute $k$th order discrete derivatives over the input points. Perhaps not surprisingly, trend filtering estimates appear to have the structure of $k$th degree spline functions, with adaptively chosen knot points (we say ``appear'' here as trend filtering estimates are not really functions over continuous domains, and are only defined over the discrete set of inputs). This brings to mind comparisons to other nonparametric regression tools that also produce adaptive splines; in particular, we compare trend filtering to smoothing splines, which penalize the sum of squared derivatives across input points, and to locally adaptive regression splines [Ann. Statist. 25 (1997) 387-413], which penalize the total variation of the $k$th derivative. Empirically, we discover that trend filtering estimates adapt to the local level of smoothness much better than smoothing splines, and further, they exhibit a remarkable similarity to locally adaptive regression splines. We also provide theoretical support for these empirical findings; most notably, we prove that (with the right choice of tuning parameter) the trend filtering estimate converges to the true underlying function at the minimax rate for functions whose $k$th derivative is of bounded variation. This is done via an asymptotic pairing of trend filtering and locally adaptive regression splines, which have already been shown to converge at the minimax rate [Ann. Statist. 25 (1997) 387-413]. At the core of this argument is a new result tying together the fitted values of two lasso problems that share the same outcome vector, but have different predictor matrices.

description: Topological Josephson junctions carry 4pi-periodic bound states. A finite bias applied to the junction limits the lifetime of the bound state by dynamically coupling it to the continuum. Another characteristic time scale, the phase adjustment time, is determined by the resistance of the circuit "seen" by the junction. We show that the 4pi periodicity manifests itself by an even-odd effect in Shapiro steps only if the phase adjustment time is shorter than the lifetime of the bound state. The presence of a peak in the current noise spectrum at half the Josephson frequency is a more robust manifestation of the 4pi periodicity, as it persists for an arbitrarily long phase adjustment time. We specify, in terms of the circuit parameters, the conditions necessary for observing the manifestations of 4pi periodicity in the noise spectrum and Shapiro step measurements.

description: Η παρούσα διπλωματική εργασία αφορά στη μελέτη, ανάλυση και ερμηνεία της περιοχής του κόλπου του Λακκιού στο νησί της Λέρου στα Δωδεκάνησα.
Για την πραγμάτωση αυτού του εγχειρήματος , κρίνεται σκόπιμο να οριοθετηθεί, τόσο ως γεωμορφολογικός  όσο και ως ανθρωπογενής χώρος. Το γεωμορφολογικό τοπίο άπτεται του φυσικού ιδιαίτερου χώρου του λιμανιού (μεγαλύτερο φυσικό λιμάνι της Μεσογείου) που σε συνδυασμό με τα παρακείμενα εποπτικά σημεία που φυσικά προσέφερε (τρία υψηλότερα σημεία του νησιού), έθεσε τις προϋποθέσεις δημιουργίας οικιστικού περιβάλλοντος.
Τα εν λόγω χαρακτηριστικά  σε συνδυασμό με τη γεωστρατηγική θέση του νησιού έπαιξαν καθοριστικό ρόλο στην ανέγερση αστικού κέντρου και την κατασκευή  οχυρωματικών έργων και ενός ισχυρού δικτύου πυροβολαρχιών στις βουνοκορφές κατά την Ιταλοκρατία (1912-1943).
Το τοπίο προσεγγίζεται ως υπαίθριος «μουσειακός» χώρος και αντιμετωπίζεται με ανάλυση δύο επιμέρους παραμέτρων: Το φυσικό χώρο του κόλπου και το ανάγλυφο του, τη μελέτη του κτιριακού περιβάλλοντος και την ερμηνεία του. Σε τρίτο επίπεδο αποπειράται η συνολική αρχιτεκτονική ανάγνωση των δύο αυτών στοιχείων με βασικό άξονα επέμβασης, τη διατήρηση της ετερότητας του τόπου. Στην παρούσα εργασία πτυχίου, επιδιώκεται η αφηγηματική προσέγγιση και όχι η δραστική παρέμβαση στο αναξιοποίητο κτιριακό απόθεμα.
Συγκεκριμένα, η ανάγνωση πραγματοποιείται σε τρία επίπεδα: Στο επίπεδο του κόλπου του Λακκιού (κλίμακα 1/10000), στο επίπεδο των λόφων του κόλπου (1/5000) και στο επίπεδο ενός επιμέρους εποπτικού χώρου (κλίμακα 1/1000). Για την ανάλυση του τρίτου επιπέδου, επελέγη η  κορυφή του όρους Πατέλλα, ως το υψηλότερο σημείο του νησιού αλλά και ως το κέντρο της Ιταλικής διοίκησης  και ο συντονισμός ολόκληρου του αντιαεροπορικού συστήματος κατά τον Β’ Παγκόσμιο Πόλεμο.
Η σύνθεση του λόφου, με κατάλοιπα πολεμικών συσκευών ηχητικής κατευθυντήριας λήψης αλλά και κτίρια στρατωνισμού κι διοίκησης , σε διάστημα  80 χρόνων, αποτελεί σήμερα αντικείμενο ιδιαίτερου ιστορικού ενδιαφέροντος και συγκεντρωτικό σημείο του περιπατητικού δικτύου του νησιού.
Η ερευνητική ιδέα της πρότασης είναι μία κίνηση, μια αφήγηση, όπου ο περιπατητής, αντικρίζει και εξετάζει στοιχεία στο περιβάλλον. Η κίνηση αυτή, ως στοχευμένη αρχιτεκτονική παρέμβαση, ενεργοποιείται  από το βίωμα και τη λειτουργία της ανάμνησης και  έχει τη δυνατότητα να αποκαλύψει και να αναδείξει την πολυπλοκότητα του αινιγματικού αυτού τοπίου.

description: In the past years, deep learning has seen an increase in usage in the domain of histopathological applications. However, while these approaches have shown great potential, in high-risk environments deep learning models need to be able to judge their uncertainty and be able to reject inputs when there is a significant chance of misclassification. In this work, we conduct a rigorous evaluation of the most commonly used uncertainty and robustness methods for the classification of Whole Slide Images, with a focus on the task of selective classification, where the model should reject the classification in situations in which it is uncertain. We conduct our experiments on tile-level under the aspects of domain shift and label noise, as well as on slide-level. In our experiments, we compare Deep Ensembles, Monte-Carlo Dropout, Stochastic Variational Inference, Test-Time Data Augmentation as well as ensembles of the latter approaches. We observe that ensembles of methods generally lead to better uncertainty estimates as well as an increased robustness towards domain shifts and label noise, while contrary to results from classical computer vision benchmarks no systematic gain of the other methods can be shown. Across methods, a rejection of the most uncertain samples reliably leads to a significant increase in classification accuracy on both in-distribution as well as out-of-distribution data. Furthermore, we conduct experiments comparing these methods under varying conditions of label noise. Lastly, we publish our code framework to facilitate further research on uncertainty estimation on histopathological data.

description: We consider the iterative reconstruction of both the internal geometry and the values of an inhomogeneous acoustic refraction index through a piecewise constant approximation. In this context, we propose two enhancements intended to reduce the number of parameters to reconstruct, while preserving accuracy. This is achieved through the use of geometrical informations obtained from a previously developed defect localization method. The first enhancement consists in a preliminary selection of relevant parameters, while the second one is an adaptive refinement to enhance precision with a low number of parameters. Each of them is numerically illustrated.

description: The collision frequency (also known as the inverse scattering lifetime) can be self-consistently calculated from the imaginary part of the zero-temperature elastic scattering cross-section in unconventional superconductors. We find these types of studies helpful to describe a hidden self-consistent damping due to incoherent fermions in two physical spaces: The Phase Space of the Nonequilibrium Statistical Mechanics, and the Configuration Space of Nonrelativistic Quantum Mechanics. The direct relation of the collision frequency with those well-known Physical Spaces is addressed in a singular way this time. Since the use of collisions for different elastic scattering regimes, is a well-developed formalism using retarded, and advanced Green functions in Many Body Physics; in order to describe our findings, we define and characterize a Reduced Phase Space for collision frequencies in the triplet strontium ruthenate compound and the singlet doped with strontium lanthanum cuprate ceramic. Both compounds display different nodal behavior of the superconducting order parameter. In this work, their zero gap behavior is numerically scanned and used to give some illustrative examples. Finally, it intuitively explores the geometrical nonlocality of the collision frequency of this type of hidden self-consistency in the Boltzmann equation, when the zero superconducting gap value drives the physics below the transition temperature, and incoherent fermions quasiparticles govern several nonequilibrium phenomena since the macroscopic behavior remarkably changes with the strontium atomic potential strength, and the concentration inherent to both compounds.

description: We investigate exotic paired states of spin-imbalanced Fermi gases in anisotropic lattices, tuning the dimension between one and three. We calculate the finite temperature phase diagram of the system using real-space dynamical mean-field theory in combination with the quantum Monte Carlo method. We find that regardless of the intermediate dimensions examined, the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state survives to reach about one third of the BCS critical temperature of the spin-density balanced case. We show how the gapless nature of the state found is reflected in the local spectral function. While the FFLO state is found at a wide range of polarizations at low temperatures across the dimensional crossover, with increasing temperature we find out strongly dimensionality-dependent melting characteristics of shell structures related to harmonic confinement. Moreover, we show that intermediate dimension can help to stabilize an extremely uniform finite temperature FFLO state despite the presence of harmonic confinement.

description: The drawdown process of an one-dimensional regular diffusion process $X$ is given by $X$ reflected at its running maximum. The drawup process is given by $X$ reflected at its running minimum. We calculate the probability that a drawdown proceeds a drawup in an exponential time-horizon. We then study the law of the occupation times of the drawdown process and the drawup process. These results are applied to address problems in risk analysis and for option pricing of the drawdown process. Finally, we present examples of Brownian motion with drift and three-dimensional Bessel processes, where we prove an identity in law.

description: Clinical trials are critically important for the development of new cancer treatments. According to recent estimates, however, clinical trial enrollment is only about 8%. Lack of patient understanding or awareness of clinical trials is one reason for the low rate of participation. The purpose of this observational study was to evaluate the readability of cancer clinical trial websites designed to educate the general public and patients about clinical trials. Nearly 90% of Americans use Google to search for health-related information. We conducted a Google Chrome Incognito search in 2018 using the keywords "cancer clinical trial" and "cancer clinical trials." Content of the 100 cancer clinical trial websites was analyzed using an online readability panel consisting of Flesch-Kincaid Grade Level, Flesch Reading Ease, Gunning-Fog Index, Coleman-Liau Index, and Simple Measure of Gobbledygook scales. Reading level difficulty was assessed and compared between commercial versus non-commercial URL extensions. Content readability was found to be "difficult" (10.7 grade level). No significant difference in readability, overall, and between commercial and non-commercial URL extensions was found using 4/5 measures of readability; 90.9% of commercial versus 49.4% of non-commercial websites were written at a >10th grade (P = .013) using Gunning-Fog Index. Written cancer clinical trials content on the Internet is written at a reading level beyond the literacy capabilities of the average American reader. Improving readability to accommodate readers with basic literacy skills will provide an opportunity for greater comprehension that could potentially result in higher rates of clinical trial enrollment.

Παρ’ όλα αυτά κοινός παρονομαστής στην πλειοψηφία των χώρων που μας περιβάλλουν είναι ο σχεδιασμός τους με πρότυπο τη νευροτυπική ιδιοσυγκρασία. Από μικρή ηλικία μαθαίνουμε να εγκλιματιζόμαστε στα συνεχώς εναλλασσόμενα περιβάλλοντα ακόμα και αν αυτές οι αλλαγές δρουν αρνητικά στην ψυχική μας υγεία. Ο τρόπος που αντιλαμβανόμαστε τα πράγματα γύρω μας αποτελεί μια προσωπική εμπειρία η οποία  διαφέρει από άτομο σε άτομο, πόσο μάλλον συγκρίνοντας νευροτυπικούς και μη ανθρώπους. Τι συμβαίνει λοιπόν στην περίπτωση μιας οικογένειας όταν υπάρχουν και μη νευροτυπικά μέλη τα οποία παρουσιάζουν έναν διαφορετικό τρόπο αντίληψης και δυσκολεύονται να ενταχθούν σε χώρους που εμείς θεωρούμε «δεδομένους» και «γνωστούς»; Αν κατανοούσαμε, για παράδειγμα, πώς αντιλαμβάνεται τον κόσμο ένας άνθρωπος με χαρακτηριστικά ψυχαναγκασμού, κατάθλιψης ή αυτισμού, θα μπορούσαμε ίσως να αλλάξουμε τις  ποιότητες ενός χώρου σύμφωνα με τα νέα δεδομένα;
Οι κύριες ερευνητικές ερωτήσεις της παρούσας εργασίας διερευνούν την ερμηνεία του περιβάλλοντος από άτομα που ανήκουν στο φάσμα του αυτισμού. Τι ποιότητες αναζητούν σε μια κατοικία και πώς επηρεάζεται ο αρχιτεκτονικός σχεδιασμός αν λάβει υπόψιν του τον τρόπο αντίληψης ανθρώπων της συγκεκριμένης ψυχικής στάσης;

description: For any $0 < α<1$, we construct Cantor sets on the parabola of Hausdorff dimension $α$ such that they are Salem sets and each associated measure $ν$ satisfies the estimate $\|{\widehat{f dν}}\|_{L^p(\mathbb{R}^2)} \leq C_p \|{f}\|_{L^2(ν)}$ for all $p >6/α$ and for some constant $C_p >0$ which may depend on $p$ and $ν$. The range $p>6/α$ is optimal except for the endpoint. The proof is based on the work of Laba and Wang on restriction estimates for random Cantor sets and the work of Shmerkin and Suomala on Fourier decay of measures on random Cantor sets. They considered fractal subsets of $\mathbb{R}^d$, while we consider fractal subsets of the parabola.

description: Ως αποτέλεσμα της τουριστικής ανάπτυξης από τα μέσα του 20ου αιώνα, η πόλη έχει ζωή κυρίως τους θερινούς μήνες και οι ροές συγκεντρώνονται στο παραλιακό μέτωπο με χρήσεις αναψυχής και εμπορίου, ενώ οι πολιτιστικές χρήσεις είναι διάσπαρτες μες στην πόλη χωρίς να συγκεντρώνονται σε ένα σύστημα.
	Η περιοχή μελέτης βρίσκεται πλησίον της κύριας εισόδου και διασχίζεται από δύο κύριους οδικούς άξονες. Αποτελεί έναν εν δυνάμει κόμβο καθώς βρίσκεται μεταξύ του Γενικού Νοσοκομείου Λασιθίου, του Αρχαιολογικού Μουσείου, του 2ου Δημοτικού Σχολείου και Νηπιαγωγείου, ενώ περιλαμβάνει και το κυκλοφοριακό πάρκο της πόλης. Σήμερα λειτουργεί ως ιδιωτικός χώρος στάθμευσης και μια φορά την εβδομάδα φιλοξενεί τη λαϊκή αγορά.
	Σκοπός της πρότασης είναι η διαμόρφωση της περιοχής ως κέντρο υπερτοπικού χαρακτήρα μέσω της διασύνδεσης των υφιστάμενων χρήσεων και της ένταξης νέων, υποστηρικτικών σε αυτές. Κύριο ζήτημα αποτελεί η διαχείριση των ορίων των περιοχών του μουσείου, του σχολείου και του νοσοκομείου και η μετάβαση από αυτή την κτιριακή κλίμακα στην πολύ μικρότερη του υπόλοιπου αστικού ιστού, σε επαφή με την περιοχή.
	Ο αστικός χώρος οργανώνεται με διαφόρων μεγεθών άξονες κίνησης σε πλατώματα και χώρους πρασίνου. Με αφετηρία το χαρακτηριστικό φυτεμένο προαύλιο χώρο του μουσείου, οι χώροι πρασίνου λειτουργούν στη συνέχεια ως φίλτρο για τις κατοικίες. Πραγματοποιείται, λοιπόν, υπέργεια σύνδεση του μουσείου με την περιοχή η οποία δημιουργεί κτίριο περιοδικών εκθέσεων το οποίο θα λειτουργεί υποστηρικτικά στο μουσείο. Το όριο με το νοσοκομείο γίνεται εγκάρσιος άξονας κίνησης, στον οποίο εντάσσεται κέντρο υγείας με αιμοδοτικό σταθμό. Επίσης, εξομαλύνεται το όριο του σχολείου και δημιουργείται μικρότερος εγκάρσιος άξονας κίνησης ο οποίος διέρχεται από τη προτεινόμενη νέα δημοτική βιβλιοθήκη της πόλης. Ένας διαμήκης άξονας κίνησης διαμορφώνεται από εμπορικά καταστήματα και χώρους αναψυχής σε κατώτερο επίπεδο, τα οποία αποτελούν συνέχεια του μικρότερης κλίμακας αστικού ιστού και της λαϊκής αγοράς. Τέλος περιορίζεται η κίνηση των αυτοκινήτων μέσα στην περιοχή και σχεδιάζεται υπόγειος χώρος στάθμευσης που θα καλύπτει τις ανάγκες όλων των παραπάνω.

description: The recent discovery of the extraordinary-log (E-Log) criticality is a celebrated achievement in modern critical theory and calls for generalization. Using large-scale Monte Carlo simulations, we study the critical phenomena of plane defects in three- and four-dimensional O($n$) critical systems. In three dimensions, we provide the first numerical proof for the E-Log criticality of plane defects. In particular, for $n=2$, the critical exponent $\hat{q}$ of two-point correlation and the renormalization-group parameter $α$ of helicity modulus conform to the scaling relation $\hat{q}=(n-1)/(2 πα)$, whereas the results for $n \geq 3$ violate this scaling relation. In four dimensions, it is strikingly found that the E-Log criticality also emerges in the plane defect. These findings have numerous potential realizations and would boost the ongoing advancement of conformal field theory.

description: The PET scanner phenoPET is a system dedicated for plant research developed and used for phenotyping studies at the Research Center in Jülich. The detector ring consists of 36 detector modules, which are equipped with LYSO scintillator crystals coupled to digital SiPMs (DPC3200 by Philips Digital Photo Counting). These photodetectors only provide digital interfaces for configuration and read-out. No electronics for analog processing are required. All detector modules are connected to a central board based on a Xilinx FPGA. On one hand, it collects and preprocesses the fast output data providing the transfer to the data storage and processing system via a USB-3 connection. On the other hand, it enables the communication between the modules and the controlling computer that sets up the detectors and controls the measurements.The USB-3 transfer restricts the maximum output rate to 380 MB/s, which requires controlled data dropping within the FPGA in order to allow measurements with activities that would exceed this limit. Presently we are developing a new readout system that will eliminate this bottleneck. We will replace the USB-3 by a fiber optics link with a maximum data rate of 2GB/s. In addition, the new central board will provide an embedded operation system (PetaLinux) that has direct access to the hardware interfaces for configuration and monitoring of the detector modules. This will replace the controlling computer and our control software can run directly on the board.

Social context
New South
Wise, Virginia

description: This thesis examines the social context that led to the emergence of country music as a commercial artform during the 1920s. It investigates the economic situation of workers, musicians and middle-class actors in the county of Wise, Virginia. It argues that country music was the product of interclass collaboration, and examines it as a cultural artifact in relation to other cultures created by the community at the time. Country music emerged during this period from a desire to alleviate the woes brought by a depressed local economy and an oppressive social stereotype. The collaboration between classes depended on the actors assertion of their own identities at a time when the meanings of the “hillbilly” shifted, and permitted a moment of self-articulation in a community dominated by the coal industry. This thesis assesses the place of coal in the lives of the people of Wise, and examines the ramifications of coal company dominance in terms of race and economics

description: Gaussian boson sampling, a computational model that is widely believed to admit quantum supremacy, has already been experimentally demonstrated and is claimed to surpass the classical simulation capabilities of even the most powerful supercomputers today. However, whether the current approach limited by photon loss and noise in such experiments prescribes a scalable path to quantum advantage is an open question. To understand the effect of photon loss on the scalability of Gaussian boson sampling, we analytically derive the asymptotic operator entanglement entropy scaling, which relates to the simulation complexity. As a result, we observe that efficient tensor network simulations are likely possible under the $N_\text{out}\propto\sqrt{N}$ scaling of the number of surviving photons orange$N_\text{out}$ in the number of input photons $N$. We numerically verify this result using a tensor network algorithm with $U(1)$ symmetry, and overcome previous challenges due to the large local Hilbert space dimensions in Gaussian boson sampling with hardware acceleration. Additionally, we observe that increasing the photon number through larger squeezing does not increase the entanglement entropy significantly. Finally, we numerically find the bond dimension necessary for fixed accuracy simulations, providing more direct evidence for the complexity of tensor networks.

description: Particle-wave duality enables the construction of interferometers for matter waves, which complement optical interferometers in precision measurement devices. This requires the development of atom-optics analogs to beam splitters, phase shifters, and recombiners. Integrating these elements into a single device has been a long-standing goal. Here we demonstrate a full Mach-Zehnder sequence with trapped Bose-Einstein condensates (BECs) confined on an atom chip. Particle interactions in our BEC matter waves lead to a non-linearity, absent in photon optics. We exploit it to generate a non-classical state having reduced number fluctuations inside the interferometer. Making use of spatially separated wave packets, a controlled phase shift is applied and read out by a non-adiabatic matter-wave recombiner. We demonstrate coherence times a factor of three beyond what is expected for coherent states, highlighting the potential of entanglement as a resource for metrology. Our results pave the way for integrated quantum-enhanced matter-wave sensors.

description: The interaction of different charged polymers, namely anionic polycarboxylate superplasticizer (PCE) and neutral polyethylene glycol (PEG) with potassium ions, and their effect on the yield stress of highly concentrated glass bead suspension (GBS), were studied under different concentrations of potassium ions ([K⁺]). It was found that, compared to the neutral PEG, the negatively charged PCE can be adsorbed on glass beads (GB), and then decreases the yield stress of GBS. The increasing concentration of free polymer in the interstitial liquid phase with the increased polymer dosage leads to the higher yield stress of GBS, which may be caused by the higher depletion force. In addition, this effect is also related to the charge density of the polymer and the [K⁺] in the solution. Along with the increase in [K⁺], the yield stress of GBS increases significantly with the addition of PCE, but this cannot be observed with PEG, which indicates that potassium ions can interact with negatively charged PCE instead of the neutral PEG. At last, the interparticle forces between two single GB with adsorbed PCE in solutions containing [K⁺] and PCE were measured by colloidal probe atomic force microscopy to better understand the interaction of the charged polymer with counterions.

description: A generalization of the Brown-Henneaux boundary conditions is introduced for pure gravity with negative cosmological constant in 3 dimensions. This leads to new degrees of freedom and to an enhancement of the symmetry algebra. Up to the zero modes, it consists of two copies of the semi-direct product of a Virasoro algebra with a U(1) current algebra. The associated surface charge algebra now contains three non-zero central charges: the two usual Brown-Henneaux central charges and one new quantity.
