description: In order to shed light on the problems one might face today trying to understand statelessness, we need to look at the historical context in which conception of the definition of statelessness took place and examine the attempts to address the issue of statelessness prior to the codification of the concept in international law by reviewing the documents from the Hague Conference (1930) and the Evian Conference (1938), the Memorandum “Statelessness and Some of its Causes: An Outline.”(1946), and “The Study of Statelessness” (1949), as well as the historical documents that describe the process leading to the conventions, such as the reports by the United Nations, academic and legal studies. I will elaborate on the close relationship between refugees and stateless people and review how it was addressed prior to the 1951 Convention Relating to the Status of Refugees and then in the 1954 Convention Relating to the Status of Stateless Persons itself. I will also revisit the debate about the place of de facto statelessness within the definition of statelessness and difficulties it created when it came to the practical application of the definition. Based on the documents reviewed for this paper, there is evidence that the way definition of statelessness was developed in international law might have been influenced by historical context. At the time of codification of the concept of statelessness, it was separated from the problem of refugees despite the fact that prior to the codification statelessness was viewed solely within the refugee problem. I believe that separation of the refugees and stateless people in international law and the introduction of the concept of de facto statelessness, which was not later included in the Convention on Statelessness, have contributed to the confusion we have today about the definition of statelessness. Finally, I will conclude my paper with the contemporary example of how the complex and confusion definition of statelessness makes it difficult to identify stateless people today and, therefore, provide them with protection 4 they need.
Defining Necessity: The Politics of Knowledge in Ontario’s and Quebec’s In Vitro Fertilization Funding Debates

description: Rapid advances in reproductive technologies have led to unprecedented shifts in debates about regulation of, and access to, these services. In a world where a single cycle of in vitro fertilization (IVF) costs upwards of $10,000, questions arise about whether and, if so, why public money should fund IVF. To examine the politics at the core of this complex ethical and practical dilemma, this thesis explores the political decision-making processes underlying two notable pieces of IVF funding legislation: Ontario’s 1993 decision to remove IVF from its government-provided health insurance and Quebec’s 2008 decision to fund three rounds of IVF for all citizens. Through these case studies, this thesis examines the patterns of interaction between non-governmental stakeholders in IVF funding decision-making forums and seeks to determine which mechanisms these stakeholders employ to shape medical funding decisions more broadly. Further, it explores the relationship between professional and lay expertise in political forums. Testing the assertions of past research, this study seeks to ascertain whether lay experts have gained substantial political credibility in these Canadian provinces. To answer these questions, I completed a textual analysis of 37 parliamentary debate records and 65 newspaper articles spanning two provinces and twelve years. I coded the records for each stakeholder’s framing of their stance on IVF issues and for the relative standing of different categories of stakeholders in both the media and political arenas. These results revealed medical professionals’ and professional organizations’ continued dominance in IVF funding decisions, particularly in Ontario. In Quebec, key lay experts, such as infertility advocacy organizations and public figures, moderated this dominance. Comparison of stakeholder standing and framing in these two cases further suggests that the greater heterogeneity of stakeholders represented in decision-making forums in Quebec was an important factor in promoting Quebec’s decision to fund the service. Indeed, while many of the same frames were deployed in the two provinces, lay experts in Quebec reinforced frames presented by professional witnesses and likely played a role in Quebec’s pro-funding decision. Ultimately, professionals still firmly control medical funding decision-making processes in Canada, though lay experts of various kinds are becoming more prominent as advocates for the public.

description: Thermal leptogenesis is a mechanism that explains the observed asymmetry between matter and antimatter in the early universe. In this study, we review the impact of nonextensive Tsallis statistical mechanics on the early universe and study its effect on thermal leptogenesis. The study has found that the use of nonextensive statistical mechanics can affect the production of baryon asymmetry in thermal leptogenesis by modifying the equilibrium abundance of particles, decay, and washout parameters. Also, we show that nonextensive statistical mechanics potentially reduce the required right-handed neutrino mass scale.

description: In this paper I offer an analysis of the critical place that “informality” occupies in the urbanistic reordering of the “Cidade Olimpica” Rio de Janeiro. Contextualizing it in Brazil’s claim to an emergent geopolitical position as a BRICS country, I explore how this reordering intersects with spatial confinement of the urban poor. I draw from examples of real estate entrepreneurialism, resettlements and territorial conflicts in Barra da Tijuca and Jacarepaguá, two of Rio de Janeiro’s rapidly transforming areas. Drawing from Judith Butler´s concept of performativity (1993), I introduce informality as a performed role and volatile ascription allowing us to understand how urban actors bargain their influence vis-à-vis unstable urban planning processes. In the making of the Olympic City, informality functions (1) as a signifier of what is perceived to be a threat to justify the stigmatization and subsequent confinement of marginalized communities as a result of local infrastructure projects related to mega-events; (2) as a signifier to justify defensive interventions against the municipal government and real estate developers by an organized upper middle-class; and (3) as a signifier around which resistances and alliances form between activist groups, researchers and NGOs on the edges of the urban fabric. Correlating urban informality and spatial confinement allows for an understanding of a spatialized, contested and performed stateness underlying city branding and also of the political mobilization of the urban poor despite of hegemonic marginalization in cities of the Global South.

description: Encoding and manipulation of quantum information by means of topological degrees of freedom provides a promising way to achieve natural fault-tolerance that is built-in at the physical level. We show that this topological approach to quantum information processing is a particular instance of the notion of computation in a noiseless quantum subsystem. The latter then provide the most general conceptual framework for stabilizing quantum information and for preserving quantum coherence in topological and geometric systems.

description: We study the quasinormal modes and thermal radiation of massless spin-0 field perturbations in the background of four-dimensional (4D) non-Abelian charged Lifshitz black branes with $z=2$ hyperscaling violation, which correspond to systems with superconducting fluctuations. After having an analytical solution to the Klein-Gordon equation, we obtain exact quasinormal modes that are purely imaginary. Therefore, there is no oscillatory behavior in the perturbations that guarantees the mode stability of these solutions. We also study the greybody factors, absorption cross-section, and decay rate of the non-Abelian charged Lifshitz black branes. We derive their analytical expressions and then investigate the correspondence in the strongly coupled dual theory. This study might shed light on the mechanism governing the high-temperature superconductors in condensed matter physics.

description: In this paper, our focus is on investigating the impact of cosmological constant on relativistic quantum systems comprising spin-0 scalar particles. Our analysis centers around the Klein-Gordon equation, and we obtain both approximate and exact analytical solutions for spin-0 particles of the quantum system. Afterwards, we explore quantum oscillator fields by considering the Klein-Gordon oscillator within the same space-time characterized by a cosmological constant. We obtain an approximate expression for the energy eigenvalue of the oscillator fields. In fact, the energy spectrum in both scenarios are examined and show the influences of the cosmological constant and geometry's topology. Our investigation is situated within the context of a magnetic universe-a four-dimensional cosmological space-time recognized as the Bonnor-Melvin universe

description: In this paper, we conduct a comprehensive exploration of the relativistic quantum dynamics of spin-0 scalar particles, as described by the Duffin-Kemmer-Petiau (DKP) equation, within the framework of a magnetic space-time. Our focus is on the Bonnor-Melvin-Lambda (BML) solution, a four-dimensional magnetic universe characterized by a magnetic field that varies with axial distance. To initiate this investigation, we derive the radial equation using a suitable wave function ansatz and subsequently employ special functions to solve it. Furthermore, we extend our analysis to include Duffin-Kemmer-Petiau oscillator fields within the same BML space-time background. We derive the corresponding radial equation and solve it using special functions. Significantly, our results show that the geometry's topology and the cosmological constant (both are related with the magnetic field strength) influences the eigenvalue solution of spin-0 DKP fields and DKP-oscillator fields, leading to substantial modifications in the overall outcomes

description: Incidental language acquisition has been a topic of interest in the field of education, cognitive psychology, and behavior analysis (Horne & Lowe, 1996; Carey & Bartlett, 1978; Greer & Speckman, 2009). Researchers in the area of verbal behavior and derived relations have developed multiple perspectives that overlap in many ways (Greer & Ross, 2008; Greer & Speckman, 2009; Hayes, Barnes-Holmes, and Roche, 2001). Despite the overlap of these perspectives, research to date has been conducted independently. Fienup (2019) acknowledges the overlap in the respective work and suggest that integration can produce a more cohesive and comprehensive understanding of the development of verbal behavior. Study 1 included two experiments. In Experiment 1, the experimenter exposed 14 preschoolers with varying degrees of bidirectional naming (3 classified as having bidirectional naming (BiN), 8 as having unidirectional naming (UniN), and 3 as having no incidental naming (NiN) to two conditions, 1) directly reinforcing speaker (tact) responses and testing for the emergence of listener (point to) responses, and 2) directly reinforcing listener responses and testing for the emergence of speaker responses. The experimenter rotated between two conditions. Results suggested that participants with BiN readily derived speaker and listener responses, participants with unidirectional naming (UniN) readily derived listener, but not speaker responses, and participants with NiN had difficulty acquiring directly reinforced responses and deriving responses. In Study 1 Experiment 2, six participants with unidirectional naming (UniN) were selected from Experiment 1. Multiple Exemplar Instruction (MEI) and stimulus-stimulus pairing procedures were implemented to induce the capability of BiN. Following the acquisition of BiN, the experimenter replicated the repeated measure design of directly reinforcing speaker or listener responses and testing for the emergence of corresponding responses. Upon the acquisition of BiN, participants derived both listener and speaker relations, suggesting that the development from UniN to BiN is associated with the stimulus control for speaker responses following direct reinforcement for listener responses. Study 2 addressed the limitations of Study 1 and replicated the procedures with new participants and new science educational content. The experimenter selected 6 participants that demonstrated BiN and 5 that demonstrated UniN. Data support the findings of Study 1, suggesting that degrees of bidirectional naming are associated with degrees of derived relational responding.

Deformation of North American Marbles in Response to Thermal Cycling

description: Marble is one of the most popular building stones in the course of human history. For several centuries it has been used as a principle façade material because of many distinctive characteristics such as color, texture, and the ability to take a highly polished polish. In the past, marble blocks used in construction had to function as load bearing elements and were sized accordingly. However, as building technology improved with the rise of steel frame construction in the 19th century, reduced wall thicknesses became possible and façade materials no longer had the same structural responsibilities. During the mid-20th century thin panels of marble, ranging from 20-50 mm, appeared as exterior cladding on structures around the world. The permanent deformation of marble panels, commonly known as bowing, has been recognized as a serious problem worldwide. Over the past few decades numerous architects, engineers, and scientists have worked toward better understanding and preventing this phenomenon. In 2000 the EU commissioned a multi-dispensary project consortium working under the acronym TEAM (Testing and Assessment of Marble and Limestone) to create a report detailing the mechanisms behind thermal deformation and develop a better understanding of bowing potential for different marble types. For obvious reasons the report focused primarily on marbles originating from Europe. Today little published scientific analysis of the effects of repeated thermal cycles on North American marbles, more specifically Tuckahoe, Colorado, Vermont, and Georgia exists. Considering that the marbles being tested vary greatly in physical characteristics as well as mineralogical composition, the potential for thermal deformation and disintegration between them will likely be just as dissimilar. For this reason, there is an important and recognizable need for a study of this type to accurately and effectively develop preservation strategies. In this study, 30 sample disks approximately 50 mm in diameter and 10 mm in thickness were prepared from four previously mentioned marble types. Each sample base contained 10 disks treated with a heating cycle, 10 disks treated with a cooling cycle, and 10 untreated disks. The samples were exposed to 60 thermal cycles, 3 cycles a day for 20 days. The cooling cycle ranged from approximately -10° C to 28° C and the heating cycle from 30° C to 63° C. Upon completion of the thermal cycling, the samples were subjected to ultrasonic velocity and biaxial flexure strength tests. The results were compiled and conclusions were drawn as to why each marble preformed the way it did as well as whether or not the marble would be suitable for use as thin panel cladding.

description: We study energetics and the nature of both homogeneous and mixed spin (MS) states in LaCoO$_3$ incorporating structural changes of the crystal volume expansion and the Co-O bond disproportionation (BD) during the spin-state transition using the density functional theory plus dynamical mean field theory (DFT+DMFT) method. DFT+DMFT predicts that energetics of both excited spin states are almost the same while DFT+U calculations of the same structures energetically favor the MS states and produce various metastable solutions whose energetics depend sensitively on final spin states. Within DFT+DMFT, the homogeneous spin state in the expanded crystal volume shows the multiconfigurational nature with non-negligible occupancy probabilities of both high spin (HS) and low spin (LS) states along with $d^6$ and $d^7$ charge configurations indicating the dynamically fluctuating nature of spin and charge states due to the Co-O covalency. The nature of the MS state under the BD structure reveals that Co sites with the long Co-O bonds develop a Mott insulating state and favor HS with a $d^6$ configuration, while more covalent Co sites with the short Co-O bonds occupy more LS states with a $d^7$ configuration and behave as a band insulator, as a result, charge ordering is induced in the BD structure from the spin-state ordering. We also find that both energetics and electronic structure sensitively depend on the Co-O covalency effect, which can be tuned by changing the double counting potential and the resulting $d-$occupancy ($N_d$), and $N_d$ close to 6.7 is consistent with the nature of the spin-state transition. Our results show that structural changes during the spin-state transition can play an important role in understanding energetics and electronic structure of LaCoO$_3$.

description: Large pretrained models are increasingly crucial in modern computer vision tasks. These models are typically used in downstream tasks by end-to-end finetuning, which is highly memory-intensive for tasks with high-resolution data, e.g., video understanding, small object detection, and point cloud analysis. In this paper, we propose Dynamic Reversible Dual-Residual Networks, or Dr$^2$Net, a novel family of network architectures that acts as a surrogate network to finetune a pretrained model with substantially reduced memory consumption. Dr$^2$Net contains two types of residual connections, one maintaining the residual structure in the pretrained models, and the other making the network reversible. Due to its reversibility, intermediate activations, which can be reconstructed from output, are cleared from memory during training. We use two coefficients on either type of residual connections respectively, and introduce a dynamic training strategy that seamlessly transitions the pretrained model to a reversible network with much higher numerical precision. We evaluate Dr$^2$Net on various pretrained models and various tasks, and show that it can reach comparable performance to conventional finetuning but with significantly less memory usage.

description: In this paper, we constrain the density of the interstellar medium (ISM) around the hadronic PeVatron candidate, supernova remnant (SNR) G106.3+2.7, based on X-ray and $γ$-ray observations. The purpose of this investigation is to understand the influence of the gaseous environment on this SNR as a proton PeVatron candidate. By modelling the self-regulated propagation of the CRs injected from the SNR, we calculate the $γ$-ray emission of CRs via the hadronuclear interactions with the molecular cloud and the ISM, and use the measured $γ$-ray flux to constrain the ISM density around the SNR. Our results support the picture that the SNR is expanding into a low-density ($n<0.05 cm^{-3}$) cavity, enabling the SNR to be a potential proton PeVatron despite that it presently is not in the very early phase.

description: We designed a novel pyrene-substituted thioethyl-porphyrazine (PzPy) and the formation of supramolecular assembly with nanocarbons demonstrating photoinduced electron transfer ability. As revealed by spectroscopic and electrochemical studies, PzPy displays wide spectral absorption in the visible range, charge separation upon photoexcitation, as well as bandgap and highest occupied/lowest unoccupied molecular orbital (HOMO/LUMO) energy values, matching the key requirements of organic optoelectronic. Moreover, the presence of a pyrene moiety promotes attractive interactions with pi-conjugated systems. In particular, theoretical calculations show that in the PzPy the HOMO and LUMO are localized on different positions of the molecule, i.e., the HOMO on the pyrene moiety and the LUMO on the macrocycle. Therefore, HOMO-LUMO excitation gives rise to a charge separation, preventing excitons recombination. Two kinds of non-covalent hybrid composites are prepared by mixing the PzPy with single wall carbon nanotubes (SWNTs) and graphene nanoflakes (GNFs), respectively, and used for photocurrent generation through charge transfer processes between PzPy and nanocarbons. Photoconduction experiments show photocurrent generation upon visible light irradiation of both PzPy/SWNT and PzPy/GNF composites (0.78 and 0.71 mA/W at 500 nm, respectively), demonstrating their suitability for optoelectronic applications and light harvesting systems.

description: This article presents a detailed analysis, based on the first-principles finite-difference time-domain method, of the resonant frequency, quality factor (Q), mode volume (V), and radiation pattern of the fundamental (HE11) mode in a three-dimensional distributed-Bragg-reflector (DBR) micropost microcavity. By treating this structure as a one-dimensional cylindrical photonic crystal containing a single defect, we are able to push the limits of Q/V beyond those achievable by standard micropost designs, based on the simple rules established for planar DBR microcavities. We show that some of the rules that work well for designing large-diameter microposts (e.g., high-refractive index contrast) fail to provide high-quality cavities with small diameters. By tuning the thicknesses of mirror layers and the spacer, the number of mirror pairs, the refractive indices of high and low refractive index regions, and the cavity diameter, we are able to achieve Q as high as 10^4, together with a mode volume of 1.6 cubic wavelengths of light in the high-refractive-index material. The combination of high Q and small V makes these structures promising candidates for the observation of such cavity quantum electrodynamics phenomena as strong coupling between a quantum dot and the cavity field, and single-quantum-dot lasing.

description: Orthogonal metal is a new quantum metallic state that conducts electricity but acquires no Fermi surface (FS) or quasiparticles, and hence orthogonal to the established paradigm of Landau's Fermi-liquid (FL). Such a state may hold the key of understanding the perplexing experimental observations of quantum metals that are beyond FL, i.e., dubbed non-Fermi-liquid (nFL), ranging from the Cu- and Fe-based oxides, heavy fermion compounds to the recently discovered twisted graphene heterostructures. However, to fully understand such an exotic state of matter, at least theoretically, one would like to construct a lattice model and to solve it with unbiased quantum many-body machinery. Here we achieve this goal by designing a 2D lattice model comprised of fermionic and bosonic matter fields coupled with dynamic $\mathbb Z_2$ gauge fields, and obtain its exact properties with sign-free quantum Monte Carlo simulations. We find that as the bosonic matter fields become disordered, with the help of deconfinement of the $\mathbb Z_2$ gauge fields, the system reacts with changing its nature from the conventional normal metal with an FS to an orthogonal metal of nFL without FS and quasiparticles and yet still responds to magnetic probe like an FL. Such a quantum phase transition from a normal metal to an orthogonal metal, with its electronic and magnetic spectral properties revealed, is calling for the establishment of new paradigm of quantum metals and their transition with conventional ones.

description: Audio-Visual Emotion Recognition (AVER) has garnered increasing attention in recent years for its critical role in creating emotion-ware intelligent machines. Previous efforts in this area are dominated by the supervised learning paradigm. Despite significant progress, supervised learning is meeting its bottleneck due to the longstanding data scarcity issue in AVER. Motivated by recent advances in self-supervised learning, we propose Hierarchical Contrastive Masked Autoencoder (HiCMAE), a novel self-supervised framework that leverages large-scale self-supervised pre-training on vast unlabeled audio-visual data to promote the advancement of AVER. Following prior arts in self-supervised audio-visual representation learning, HiCMAE adopts two primary forms of self-supervision for pre-training, namely masked data modeling and contrastive learning. Unlike them which focus exclusively on top-layer representations while neglecting explicit guidance of intermediate layers, HiCMAE develops a three-pronged strategy to foster hierarchical audio-visual feature learning and improve the overall quality of learned representations. To verify the effectiveness of HiCMAE, we conduct extensive experiments on 9 datasets covering both categorical and dimensional AVER tasks. Experimental results show that our method significantly outperforms state-of-the-art supervised and self-supervised audio-visual methods, which indicates that HiCMAE is a powerful audio-visual emotion representation learner. Codes and models will be publicly available at https://github.com/sunlicai/HiCMAE.

description: While recent advances in deep learning have significantly advanced the state of the art for vessel detection in color fundus (CF) images, the success for detecting vessels in fluorescein angiography (FA) has been stymied due to the lack of labeled ground truth datasets. We propose a novel pipeline to detect retinal vessels in FA images using deep neural networks that reduces the effort required for generating labeled ground truth data by combining two key components: cross-modality transfer and human-in-the-loop learning. The cross-modality transfer exploits concurrently captured CF and fundus FA images. Binary vessels maps are first detected from CF images with a pre-trained neural network and then are geometrically registered with and transferred to FA images via robust parametric chamfer alignment to a preliminary FA vessel detection obtained with an unsupervised technique. Using the transferred vessels as initial ground truth labels for deep learning, the human-in-the-loop approach progressively improves the quality of the ground truth labeling by iterating between deep-learning and labeling. The approach significantly reduces manual labeling effort while increasing engagement. We highlight several important considerations for the proposed methodology and validate the performance on three datasets. Experimental results demonstrate that the proposed pipeline significantly reduces the annotation effort and the resulting deep learning methods outperform prior existing FA vessel detection methods by a significant margin. A new public dataset, RECOVERY-FA19, is introduced that includes high-resolution ultra-widefield images and accurately labeled ground truth binary vessel maps.
