description: We present spatially- and spectrally-resolved photoluminescence measurements of indirect excitons in high magnetic fields. Long indirect exciton lifetimes give the opportunity to measure magnetoexciton transport by optical imaging. Indirect excitons formed from electrons and holes at zeroth Landau levels (0e - 0h indirect magnetoexcitons) travel over large distances and form a ring emission pattern around the excitation spot. In contrast, the spatial profiles of 1e - 1h and 2e - 2h indirect magnetoexciton emission closely follow the laser excitation profile. The 0e - 0h indirect magnetoexciton transport distance reduces with increasing magnetic field. These effects are explained in terms of magnetoexciton energy relaxation and effective mass enhancement.

description: Outstanding crystalline perfection is a key requirement for the formation of new forms of electronic order in a vast number of widely different materials. Whereas excellent sample quality represents a standard claim in the literature, there are, quite generally, no reliable microscopic probes to establish the nature and concentration of lattice defects such as voids, dislocations and different species of point defects on the level relevant to the length and energy scales inherent to these new forms of order. Here we report an experimental study of the archetypical skyrmion-lattice compound MnSi, where we relate the characteristic types of point defects and their concentration to the magnetic properties by combining different types of positron spectroscopy with ab-initio calculations and bulk measurements. We find that Mn antisite disorder broadens the magnetic phase transitions and lowers their critical temperatures, whereas the skyrmion lattice phase forms for all samples studied underlining the robustness of this topologically non-trivial state. Taken together, this demonstrates the unprecedented sensitivity of positron spectroscopy in studies of new forms of electronic order.

description: We present a computer-aided detection algorithm for polyps in optical colonoscopy images. Polyps are the precursors to colon cancer. In the US alone, more than 14 million optical colonoscopies are performed every year, mostly to screen for polyps. Optical colonoscopy has been shown to have an approximately 25% polyp miss rate due to the convoluted folds and bends present in the colon. In this work, we present an automatic detection algorithm to detect these polyps in the optical colonoscopy images. We use a machine learning algorithm to infer a depth map for a given optical colonoscopy image and then use a detailed pre-built polyp profile to detect and delineate the boundaries of polyps in this given image. We have achieved the best recall of 84.0% and the best specificity value of 83.4%.

The pari passu principle in insolvency law: an analysis of the judicial construct and its suitability for modern needs
Creators: name: Mamutse, Blanca
Publisher: name: University of Westminster
Year: 2009

description: The subject of this thesis is the pari passu rule in English law. That rule, commonly understood, provides for equal (or pro rata) treatment of creditors belonging to the same class. The rule has been developed through both legislative and judicial activities over a long passage of legal history. This thesis will analyse the construct given to this rule by both legislators and judges, particularly, with reference to the extent it has been adapted to meet the needs of modern insolvency law. Such a perspective is especially acute in the light of recent reforms to the position of unsecured creditors introduced by the Enterprise Act 2002. The effects of the current financial downturn have furthermore focused attention on insolvency law from the perspective of corporate rescue or the treatment of creditors, and the increasingly global nature of commerce has meant that different jurisdictions face similar challenges in the enforcement of their insolvency laws. This work engages in a doctrinal study which contrasts the conception of the pari passu rule which is widely known and applied (though subject to criticism) with the actual operation of the rule in a private law and public policy context. Accordingly, the development of the rule is traced from its origins to its present application. An effort is made to determine the extent to which the judicial model of pari passu is substantiated in practice and commercial realities. It is argued that this model can be distinguished from the manner in which the rule actually applies in the context of managing the relationship between unsecured creditors within their class, and in the promotion of wider social interests. Regard is made of developments in insolvency law which may have diminished the view of the rules of insolvency distribution as an indicator of the social values of a legal system. The manifestation of the rule in ‘international insolvencies’ is one such development. An examination of the advent of a more flexible approach to pari passu in international insolvencies would thus be necessary. It will be shown that a revised construct of pari passu which more strongly accords with modern imperatives is needed. This study centres primarily on United Kingdom insolvency law, and draws on the experience of other (mainly common law) jurisdictions to demonstrate important issues in the enforcement of the pari passu rule and provide comparisons, where appropriate.

description: To optimize the performance of the Collinear Resonance Ionization Spectroscopy (CRIS) experiment at CERN-ISOLDE, technical upgrades are continuously introduced, aiming to enhance its sensitivity, precision, stability, and efficiency. Recently, a voltage-scanning setup was developed and commissioned at CRIS, which improved the scanning speed by a factor of three as compared to the current laser-frequency scanning approach. This leads to faster measurements of the hyperfine structure for systems with high yields (more than a few thousand ions per second). Additionally, several beamline sections have been redesigned and manufactured, including a new field-ionization unit, a sharper electrostatic bend, and improved ion optics. The beamline upgrades are expected to yield an improvement of at least a factor of 5 in the signal-to-noise ratio by suppressing the non-resonant laser ions and providing time-of-flight separation between the resonant ions and the collisional background. Overall, the presented developments will further improve the selectivity, sensitivity, and efficiency of the CRIS technique.

Social Distance: Urban Prairie Landscapes and The Production of Forced Distance Through Public Ecology
Creators: name: Morgan, Hunter J.
Publisher: name: University of Chicago
Year: 2021

description: Over the past year, the COVID-19 pandemic has forced us all to dramatically reconsider how we exist within and engage with public spaces. Drawing from the exigency of this moment, I employ the practice of social distance (a framework taken from the context of the pandemic but with a long history in the social sciences) to explore the relations between public landscapes and the communities that move within them. In exploring this practice within urban space, I focus this essay on prairie restoration administrative policies pursued by the Chicago Park District across Chicago over the past 30 years. In producing these landscapes, I argue that city agencies work to create urban landscapes existing outside of conventional expectations for public ecology. Namely, through producing practices of social distance within urban space, I argue that prairie restoration policies, as a form of intentional design, create separation between individuals and deteriorate the role of parks as a space for collective utilization. Using ethnographic, autoethnographic, and archival methods, I focus on how these areas produce both physical and subaltern practices of social distance through their physical construction and the historical narratives that are spatialized within them. Moreover, I then go into a discussion of how this distance affects and reframes the role of the public while catering to the interests of the private developers and conservationists that create these geographies in the first place.

description: We investigate two stripped-envelope supernovae (SNe) discovered in the nearby galaxy NGC 5806 by the (i)PTF. These SNe, designated PTF12os/SN 2012P and iPTF13bvn, exploded at a similar distance from the host-galaxy center. We classify PTF12os as a Type IIb SN based on our spectral sequence; iPTF13bvn has previously been classified as Type Ib having a likely progenitor with zero age main sequence (ZAMS) mass below ~17 solar masses. Our main objective is to constrain the explosion parameters of iPTF12os and iPTF13bvn, and to put constraints on the SN progenitors. We present comprehensive datasets on the SNe, and introduce a new reference-subtraction pipeline (FPipe) currently in use by the iPTF. We perform a detailed study of the light curves (LCs) and spectral evolution of the SNe. The bolometric LCs are modeled using the hydrodynamical code HYDE. We use nebular models and late-time spectra to constrain the ZAMS mass of the progenitors. We perform image registration of ground-based images of PTF12os to archival HST images of NGC 5806 to identify a potential progenitor candidate. Our nebular spectra of iPTF13bvn indicate a low ZAMS mass of ~12 solar masses for the progenitor. The late-time spectra of PTF12os are consistent with a ZAMS mass of ~15 solar masses. We successfully identify a progenitor candidate to PTF12os using archival HST images. This source is consistent with being a cluster of massive stars. Our hydrodynamical modeling suggests that the progenitor of PTF12os had a compact He core with a mass of 3.25 solar masses, and that 0.063 solar masses of strongly mixed 56Ni was synthesized. Spectral comparisons to the Type IIb SN 2011dh indicate that the progenitor of PTF12os was surrounded by a hydrogen envelope with a mass lower than 0.02 solar masses. We also find tentative evidence that the progenitor of iPTF13bvn could have been surrounded by a small amount of hydrogen.

Subjects: single-cell, BCR, deep learning, CNN,

description: B cells are critical for adaptive immunity and are governed by the recognition of an antigen by the B cell receptor (BCR), a process that drives a coordinated series of signaling events and modulation of various transcriptional programs. Single-cell RNA sequencing with paired BCR profiling could offer insights into numerous physiological and pathological processes. However, unlike the plethora of single-cell RNA analysis pipelines, computational tools that utilize single-cell BCR sequences for further analyses are not yet well developed. Here we report Ibex, which vectorizes the amino acid sequence of the complementarity-determining region 3 (cdr3) of the immunoglobulin heavy and light chains, allowing for unbiased dimensional reduction of B cells using their BCR repertoire. Ibex is implemented as an R package with integration into both the Seurat and Single-Cell Experiment framework, enabling the incorporation of this new analytic tool into many single-cell sequencing analytic workflows and multimodal experiments.

description: Solid-state control of the thermal conductivity of materials is of exceptional interest for novel devices such as thermal diodes and switches. Here, we demonstrate the ability to continuously tune the thermal conductivity of nanoscale films of $\rm La_{0.5}Sr_{0.5}CoO_{3-δ}$ (LSCO) by a factor of over 5, via a room-temperature electrolyte-gate-induced non-volatile topotactic phase transformation from perovskite (with $δ\approx 0.1$) to an oxygen-vacancy-ordered brownmillerite phase (with $δ=0.5$), accompanied by a metal-insulator transition. Combining time-domain thermoreflectance and electronic transport measurements, model analyses based on molecular dynamics and Boltzmann transport, and structural characterization by X-ray diffraction, we uncover and deconvolve the effects of these transitions on heat carriers, including electrons and lattice vibrations. The wide-range continuous tunability of LSCO thermal conductivity enabled by low-voltage (below 4 V) room-temperature electrolyte gating opens the door to non-volatile dynamic control of thermal transport in perovskite-based functional materials, for thermal regulation and management in device applications.

description: In order to better define a citation model for cultural heritage objects and to formulate concrete proposals for its application, three digital repositories were selected as case studies: Archaeological Data Service (ADS), Digital Repository of Ireland (DRI), and Phaidra - University of Padua. To this end, a descriptive model specifically designed to meet semantic citation criteria from a cit(ation)-actionability perspective was defined and implemented to collect relevant information about the repositories under study and their data citation practices. The model is available as an annex to this document. The citation records currently used by the selected repositories were illustrated and discussed on the basis of some example data objects, highlighting the strengths and weaknesses identified in terms of semantic reference to cultural heritage objects. This is followed by suggestions for the improvement of the repository citation model. Part of A FAIR-enabling citation model for Cultural Heritage Objects project activities.

description: It was shown recently that the Minkowski content of a bounded set $A$ in $\mathbb{R}^d$ with volume zero can be characterized in terms of the asymptotic behaviour of the boundary surface area of its parallel sets $A_r$ as the parallel radius $r$ tends to $0$. Here we discuss localizations of such results. The asymptotic behaviour of the local parallel volume of $A$ relative to a suitable second set $Ω$ can be understood in terms of the suitably defined local surface area relative to $Ω$. Also a measure version of this relation is shown: Viewing the Minkowski content as a locally determined measure, this measure can be obtained as a weak limit of suitably rescaled surface measures of close parallel sets. Such measure relations had been observed before for self-similar sets and some self-conformal sets in $\mathbb{R}^d$. They are now established for arbitrary closed sets, including even the case of unbounded sets. The results are based on a localization of Stachó's famous formula relating the boundary surface area of $A_r$ to the derivative of the volume function at $r$.

description: RESUMO: Com o avançar da idade, as mudanças que ocorrem no corpo e na saúde podem afetar a voz e a capacidade de cantar. No entanto, a música pode ser benéfica para a saúde mental e física dos idosos. Por isso, é fundamental que os profissionais que trabalham com esse público tenham estratégias adequadas para lidar com as limitações vocais e físicas dessa faixa etária. Nesse sentido, é importante desenvolver repertórios específicos para os coros formados por idosos, que levem em conta limitações e necessidades vocais do grupo. Além de garantir a qualidade da música produzida, essa iniciativa também pode promover a sensação de pertencimento e participação ativa na sociedade. Com o objetivo de auxiliar os profissionais que trabalham com coros voltados para essa faixa etária, propomos a criação de um repertório específico para coralistas amadores acima dos 60 anos. Acreditamos que essa iniciativa pode contribuir significativamente para a promoção da saúde e do bem-estar dos idosos, sem perder o foco na performance artística do coro.

 ABSTRACT: With increasing age, changes occurring in the body and health can affect the voice and the ability to sing. However, music can be helpful for the mental and physical health of older adults. Therefore, it is essential for professionals who work with these individuals to develop proper strategies to deal with the vocal and physical limitations of this age group. In this sense, it is important to develop specific repertoire for choirs composed by elderly people, which take into account the group's vocal limitations and needs. In addition to ensuring the quality of the music, this initiative can also promote a sense of belonging and active participation in society. Aiming to assist professionals who work with choirs focused on this age group, we propose the creation of a specific repertoire for amateur choristers over 60 years old. We believe that this approach can contribute significantly to the promotion of health and well-being of elderly people, without losing focus on the artistic performance of the choir.

description: The molecular phase of hydrogen converts to the atomic metallic phase at high pressures estimated usually as 300 - 500 GPa. We analyze the decay of metallic phase as the pressure is relieved below the transition one. The metallic state is expected to be in the metastable long-lived state down to about 10 - 20 GPa and decays instantly at the lower pressures. The pressure range of the long-lived metastable state is directly associated with an impossibility to produce a stable hydrogen molecule immersed into the electron liquid of high density. For lower pressures, the nucleation of an electron-free cavity with the energetically favorable hydrogen molecule inside cannot be suppressed with the low ambient pressure.

We reported a total of 53 weaknesses, stemming from insecure by design practices or basic security design failures. They enable attackers to take a device offline, manipulate its operational parameters, and execute arbitrary code without any constraint. We discuss why vulnerable products are often security certified and appear to be more secure than they actually are, and we explain complicating factors of OT risk management.

description: In this paper, the authors propose a new approach to solving the groundwater flow equation in the Toth basin of arbitrary top and bottom topographies using deep learning. Instead of using traditional numerical solvers, they use a DeepONet to produce the boundary-to-solution mapping. This mapping takes the geometry of the physical domain along with the boundary conditions as inputs to output the steady state solution of the groundwater flow equation. To implement the DeepONet, the authors approximate the top and bottom boundaries using truncated Fourier series or piecewise linear representations. They present two different implementations of the DeepONet: one where the Toth basin is embedded in a rectangular computational domain, and another where the Toth basin with arbitrary top and bottom boundaries is mapped into a rectangular computational domain via a nonlinear transformation. They implement the DeepONet with respect to the Dirichlet and Robin boundary condition at the top and the Neumann boundary condition at the impervious bottom boundary, respectively. Using this deep-learning enabled tool, the authors investigate the impact of surface topography on the flow pattern by both the top surface and the bottom impervious boundary with arbitrary geometries. They discover that the average slope of the top surface promotes long-distance transport, while the local curvature controls localized circulations. Additionally, they find that the slope of the bottom impervious boundary can seriously impact the long-distance transport of groundwater flows. Overall, this paper presents a new and innovative approach to solving the groundwater flow equation using deep learning, which allows for the investigation of the impact of surface topography on groundwater flow patterns.

description: Recently, optical technologies have found several applications in fields including biophotonics, precision metrology and wavelength scale sensors. However, to gather statistically relevant information and analysis these methods require large amount of measurements. Current linear multivariate methods such as principal component analysis or linear discriminant analysis are not sufficient to analyze these big datasets with non-linear variability. Recently, the application of deep learning based artificial neural networks have found an upsurge in various areas of science ranging from quantum physics to evolutionary biology, providing an enhancement in the efficiency of various techniques. This thesis focuses on the applications of machine learning with the goal to enhance different aspects of biophotonics. Firstly, this thesis explores the application machine learning to enhance the label-free characterization of cells of the immune system using Raman spectroscopy and digital holographic microscopy. The combination of deep learning with digital holographic microscopy provides a route towards a high throughput hemogram device which would be useful for the classification of clinically important immune cells with morphological similarities but different functions. Following this, the applications of deep learning are explored in the regime of precision optical metrology for the development of a laser speckle wavemeter with a high dynamic range with an additional application for the development of a binary speckle based spectrometer. Finally, the application of machine learning based methods are also explored to improve the sensitivity of the chirped guided mode biosensor. A comparison between the linear method of principal component analysis and direct Fano fitting is drawn which is followed by the application of multi layered perceptron for further improvement.

description: In this paper, we show that the destruction of the main KAM islands in two-degree-of-freedom Hamiltonian systems occurs through a cascade of period-doubling bifurcations. We calculate the corresponding Feigenbaum constant and the accumulation point of the period-doubling sequence. By means of a systematic grid search on exit basin diagrams, we find the existence of numerous very small KAM islands ('islets') for values below and above the aforementioned accumulation point. We study the bifurcations involving the formation of islets and we classify them in three different types. Finally, we show that the same types of islets appear in generic two-degree-of-freedom Hamiltonian systems and in area-preserving maps.

“Yo Perreo Sola”: Boundary Crossing In Reggaeton
Creators: name: Burgos, Eva Cecilia
Publisher: name: University of Chicago
Year: 2021

description: In this thesis, I will examine modern reggaeton through a combination of musical analysis and interviews. Although there have been significant writings on reggaeton, its development, and its explosion in the late 90’s and early 2000’s, few have written extensively about the reggaeton of the last five years or so. Reggaeton has transformed significantly in recent years, especially with the progressive and experimental contributions of such artists as Bad Bunny. I will focus on the ways reggaeton has transgressed and transcended musical, cultural, and ideological boundaries by analyzing music award shows, events like the Super Bowl, as well as recent releases and music videos by reggaeton artists. I argue that recent changes in reggaeton have attracted a new generation of listeners, cultivating an increasingly diverse pan-Latinx identity in the process. Reggaeton has moved beyond standard genre conventions and is no longer defined by the dembow beat, but instead continues to develop into a broader style that is becoming more inclusive than ever before.

The anatomy of the war crimeof attacking peacekeepersunder internationalhumanitarian law andinternational criminal law
Creators: name: Sonczyk, Barbara
Publisher: name: University of Westminster
Year: 2014

description: This thesis is concerned with the analysis of the war crime of attacking peacekeeping missions under international humanitarian law and international criminal law. The Rome Statute of the International Criminal Court criminalises “(…) intentionally directing attacks against personnel, installations, material, units or vehicles involved in a humanitarian assistance or peacekeeping mission in accordance with the Charter of the United Nations, as long as they are entitled to the protection given to civilians or civilian objects under the international law of armed conflict”. However, the exact scope of application of this war crime is unclear and controversial due to the overlap of three different fields of international law: international criminal law, international humanitarian law and United Nations law. These distinct bodies of law have their own principles, objectives and logic and might not necessarily be in perfect harmony with each other at this particular point. Major complexities linked to it include the definition of a peacekeeping mission in accordance with the Charter of the United Nations, the status of peacekeeping personnel and objects under international humanitarian law, and the scope of peacekeepers’ right to self-defence. The central research question that this thesis addresses is about the compatibility of this war crime with the system of international law. This is answered in the affirmative. The contribution to knowledge that this thesis offers relates to critical studies on international criminal law, international humanitarian law and the United Nations system. The thesis clarifies the scope of application of the war crime of attacking personnel and objects involved in a peacekeeping mission in accordance with the United Nations Charter. This is the first comprehensive analysis of the overlap of legal regimes with respect to this war crime, which can assist courts in application of the rules relating to the protection of peacekeeping missions.
Optimal well-posedness for the inhomogeneous incompressible Navier-Stokes system with general viscosity

description: In this paper we obtain new well-possedness results concerning a linear inhomogenous Stokes-like system. These results are used to establish local well-posedness in the critical spaces for initial density $ρ_{0}$ and velocity $u_{0}$ such that $ρ_{0}-ρ\in\dot{B}_{p,1}^{\frac{3}{p}}(\mathbb{R}^{3})$, $u_{0}\in\dot{B}_{p,1}^{\frac{3}{p}-1}(\mathbb{R}^{3})$, $p\in\left( \frac{6}{5},4\right) $, for the inhomogeneous incompressible Navier-Stokes system with variable viscosity. To the best of our knowledge, regarding the $3D$ case, this is the first result in a truly critical framework for which one does not assume any smallness condition on the density.
State of Health Assessment of Spent Lithium-Ion Batteries Based on Voltage Integral During the Constant Current Charge

description: Lithium-ion battery (LIB) is used in many personal electronic devices (PED) and energy-demanding applications such as electric vehicles. After their first use, rather than dispose of them for recycling, some may have reasonable capacity and can be used in a secondary application. The current test methods to assess them are either slow, complex or expensive. The voltage integral during the constant current (CC) charge of the same model LIBs strongly correlates with the state of health (SOH) and is faster than a full capacity check. As against the filtering requirement in the incremental capacity (IC), Differential Voltage (DV) or the complex analysis in the electrochemical impedance spectrum(EIS), the voltage integral offers simple integration, just like the simple capacity Coulomb’s counter that is installed in many BMS for estimating the SOC of LIBs. By obtaining the voltage integral of a relatively new cell and an old cell of the same model with known SOH at a given ambient temperature and CC charge, the SOH of other similar cells can be easily estimated by finding their voltage integral. This research was funded by the German Academic Exchange Service (DAAD) and 335 Petroleum Technology Development Fund (PTDF) under the Nigerian-German Postgraduate Training Programme PhD, 2022, grant number 57610608.
Distribution of Shapes of orthogonal Lattices

description: It was recently shown by Aka, Einsiedler and Shapira that if d>2, the set of primitive vectors on large spheres when projected to the d-1-dimensional sphere coupled with the shape of the lattice in their orthogonal complement equidistribute in the product space of the sphere with the space of shapes of d-1-dimensional lattices. Specifically, for d=3,4,5 some congruence conditions are assumed. By using recent advances in the theory of unipotent flows, we effectivize the dynamical proof to remove those conditions for d=4,5. It also follows that equidistribution takes place with a polynomial error term with respect to the length of the primitive points.
Disk flaring with TNG50: diversity across Milky Way and M31 analogs

description: We use the sample of 198 Milky Way (MW) and Andromeda (M31) analogs from TNG50 to quantify the level of disk flaring predicted by a modern, high-resolution cosmological hydrodynamical simulation. Disk flaring refers to the increase of vertical stellar disk height with galactocentric distance. The TNG50 galaxies are selected to have stellar disky morphology, a stellar mass in the range of $M_* = 10^{10.5 - 11.2}~\rm{M_{\odot}}$, and a MW-like Mpc-scale environment at $z=0$. The stellar disks of such TNG50 MW/M31 analogs exhibit a wide diversity of structural properties, including a number of galaxies with disk scalelength and thin and thick disk scaleheights that are comparable to those measured or inferred for the Galaxy and Andromeda. With one set of physical ingredients, TNG50 returns a large variety of flaring flavours and amounts, also for mono-age stellar populations. With this paper, we hence propose a non-parametric characterization of flaring. The typical MW/M31 analogs exhibit disk scaleheights that are $1.5-2$ times larger in the outer than in the inner regions of the disk for both old and young stellar populations, but with a large galaxy-to-galaxy variation. Which stellar population flares more, and by how much, also varies from galaxy to galaxy. TNG50 de facto brackets existing observational constraints for the Galaxy and all previous numerical findings. A link between the amount of flaring and the $z=0$ global galaxy structural properties or merger history is complex. However, a connection between the scaleheights and the local stellar vertical kinematics and gravitational potential is clearly in place.

A Coherent Quantum Annealer with Rydberg Atoms

description: There is a significant ongoing effort in realizing quantum annealing with different physical platforms. The challenge is to achieve a fully programmable quantum device featuring coherent adiabatic quantum dynamics. Here we show that combining the well-developed quantum simulation toolbox for Rydberg atoms with the recently proposed Lechner-Hauke-Zoller~(LHZ) architecture allows one to build a prototype for a coherent adiabatic quantum computer with all-to-all Ising interactions and, therefore, a novel platform for quantum annealing. In LHZ a infinite-range spin-glass is mapped onto the low energy subspace of a spin-1/2 lattice gauge model with quasi-local 4-body parity constraints. This spin model can be emulated in a natural way with Rubidium and Cesium atoms in a bipartite optical lattice involving laser-dressed Rydberg-Rydberg interactions, which are several orders of magnitude larger than the relevant decoherence rates. This makes the exploration of coherent quantum enhanced optimization protocols accessible with state-of-the-art atomic physics experiments.
