description: We investigate the performance of majority-logic decoding in both reversible and finite-time information erasure processes performed on macroscopic bits that contain $N$ microscopic binary units. While we show that for reversible erasure protocols single-unit transformations are more efficient than majority-logic decoding, the latter is found to offer several benefits for finite-time erasure processes: Both the minimal erasure duration for a given erasure and the minimal erasure error for a given erasure duration are reduced, if compared to a single unit. Remarkably, the majority-logic decoding is also more efficient in both the small erasure error and fast erasure region. These benefits are also preserved under the optimal erasure protocol that minimizes the dissipated heat. Our work therefore shows that majority-logic decoding can lift the precision-speed-efficiency trade-off in information erasure processes.

description: In this talk we present the results obtained from a study of ${\cal O}(2000)$ (quenched) lattice configurations from the APE collaboration, at $6.0\leβ\le 6.4$, using both the Wilson and the SW-Clover fermion action. We determine the light hadronic spectrum and the meson decay constants. For the light-light systems we find an agreement with the experimental data of $\sim 5%$ for mesonic masses and $\sim 10%-15%$ for baryonic masses and pseudoscalar decay constants; a larger deviation is present for the vector decay constants. For the heavy-light decay constants we find $f_{D_s}=237 \pm 16 MeV, f_{D} = 221 \pm 17 MeV (f_{D_s}/f_D=1.07(4)), f_{B_s} = 205 \pm 35 MeV, f_{B} = 180 \pm 32 MeV (f_{B_s}/f_B=1.14(8))$, in good agreement with previous estimates.

description: While modern machine learning and deep learning seem to dominate the areas where scalability and modeling flexibility are required, Bayesian methods shine out when people are seeking interpretation and high-quality uncertainty estimation. Appreciating the beauty of Bayesian statistics, I have been dedicated to tractable Bayesian inference and interpretable modeling, and especially interested in Markov chain Monte Carlo (MCMC) on which Bayesian inference has highly depended until variational inferences was invented to provide an alternative solution. Therefore, I develop novel algorithms in MCMC and variation inference and interpretable models to explain complex mechanisms. Proposed in the thesis are novel Bayesian inference algorithms and modeling framework to solve various fundamental problems in statistics, including general-purpose statistical inference with uncertainty quantification, multinomial classification and survival analysis. Tremendous help was given by my Ph.D. advisor, the committee members and other collaborators and a lot of inspirations were ignited amid cooperation. In the first chapter of the thesis, we introduce MCMC-interactive variational inference that utilizes the complementary advantages of MCMC and variational inference. This inference algorithm not only accurately and efficiently estimates the posteriors, but also facilitates designs of stochastic gradient MCMC and transition kernels for Gibbs sampling. In the second chapter, we propose a permuted and augmented stick-breaking construction as sequential decision making to extend any binary classifier using a cross-entropy loss to a Bayesian multinomial one, so that favorable properties of the binary classifier can be preserved. We develop a data augmentation scheme and an efficient Metropolis-Hastings algorithm to transform the sequential decision making problem into several conditionally independent ones so that parallel computing can be used. In the third chapter, we propose Weibull delegate racing to explicitly model surviving under competing events and to interpret non-monotonic covariate effects by an intuitive two-phase racing mechanism. For inference, we develop a Gibbs-sampling-based MCMC algorithm with data augmentations along with a maximum a posteriori estimation algorithm for big data analysis. As an application, we analyze time to loan payoff and default on Prosper.com, demonstrating not only distinguished model performance, but also the value of standard and soft information on this peer-to-peer lending platform.
Rate of Melt Ascent beneath Iceland from the Magmatic Response to Deglaciation

description: Observations of the time lag between the last deglaciation and a surge in volcanic activity in Iceland constrain the average melt ascent velocity to be $\geq50$ $\mathrm{m/yr}$. Although existing theoretical work has explained why the surge in eruption rates increased $5$-$30$ fold from the steady-state rates during the last deglaciation, they cannot account for large variations of Rare Earth Element (REE) concentrations in the Icelandic lavas. Lavas erupted during the last deglaciation are depleted in REEs by up to $70\%$; whereas, existing models, which assume instantaneous melt transport, can only produce at most $20\%$ depletion. Here, we develop a numerical model with finite melt ascent velocity and show that the variations of REEs are strongly dependent on the melt ascent velocity. When the average melt ascent velocity is $100$ $\mathrm{m/yr}$, the variation of $\mathrm{La}$ calculated by our model is comparable to that of the observations. In contrast, when the melt ascent velocity is $1,000$ $\mathrm{m/yr}$ or above, the model variation of $\mathrm{La}$ becomes significantly lower than observed, which explains why previous models with instantaneous melt transport did not reproduce the large variations. We provide the first model that takes account of the diachronous response of volcanism to deglaciation. We show by comparing our model calculations of the relative volumes of different eruption types (subglacial, finiglacial and postglacial) and the timing of the bursts in volcanic eruptions with the observations across different volcanic zones that the Icelandic average melt ascent velocity during the last deglaciation is likely to be $\sim100$ $\mathrm{m/yr}$.

description: No abstracts are to be cited without prior reference to the author.This study reflects the long‐term (1920–2010) changes in the structures of the Polish long‐distance and Baltic Sea fisheries, considered in light of variation in the state’s economic system. The species composition of annual landings, technical support, and employment in the fisheries is analysed. Development of the Baltic fishery was initiated after World War I, with the logistical and technical support of the government. In 1920, the Polish fishing fleet operated in the Baltic Sea only and was composed of 55 motor‐cutters, 16 sail‐cutters, and 800 smaller boats, managed by private owners, locally associated in the Kashubian Maszoperia. At that time 1086 fishers were active and annual landings were 800 tons, with sprat, flatfish, and herring dominant. In 1931, eight Polish vessels operated outside the Baltic for the first time. From 1947, the Baltic fishery was conducted by cooperative, private, and state fleets. Dynamic development of the long‐distance fishery, which was steered by the state, started in 1960 and over the next 30 years dominated the Baltic fishery. The historically highest landing (816.7 × 103 tons) of marine species was recorded in 1975, of which 74% originated from 130 vessels operating outside the Baltic. In 1999, total landings decreased by about four times and only 42% was achieved outside the Baltic. In the 1990s the process of privatization of the Polish fishing fleet started. At the beginning of the 2000s, a gradual collapse of the long‐distance fishery (in 2010 four vessels remained) was observed. In 2004–2010, 501 (38%) Polish vessels were removed from the Baltic fishery, and annual landings decreased by 28%.

By numerically evolving a network of cosmic strings we generate full-sky CMB temperature anisotropy maps. Based on $192$ maps, we compute the anisotropy power spectrum for multipole moments $\ell \le 20$. By comparing with the observed temperature anisotropy, we set the normalization for the cosmic string mass-per-unit-length $μ$, obtaining $Gμ/c^2=1.05 {}^{+0.35}_{-0.20} \times10^{-6}$, which is consistent with all other observational constraints on cosmic strings. We demonstrate that the anisotropy pattern is consistent with a Gaussian random field on large angular scales.

description: Scaling theory, duality symmetry, and numerical simulations of a random network model are used to study the magnetoresistance of a metal/insulator/perfect conductor composite with a disordered columnar microstructure. The phase diagram is found to have a critical line which separates regions of saturating and non-saturating magnetoresistance. The percolation problem which describes this line is a generalization of anisotropic percolation. We locate the percolation threshold and determine the t = s = 1.30 +- 0.02, nu = 4/3 +- 0.02, which are the same as in two-constituent 2D isotropic percolation. We also determine the exponents which characterize the critical dependence on magnetic field, and confirm numerically that nu is independent of anisotropy. We propose and test a complete scaling description of the magnetoresistance in the vicinity of the critical line.

description: The intricate relationship between climate change, female migration, and food security in the context of the Capitalocene demands a holistic approach. Interdisciplinary analysis reveals that women are essential agents in both responses and vulnerabilities associated with these phenomena. Addressing the challenges of female migration requires policies that take into account not only climatic aspects but also the gender power structures that shape these experiences. The main objective of this research is to investigate and understand, using an interdisciplinary approach, the complex relationship between climate change caused by theCapitalocene, population displacements focusing on female migrations from the perspective of feminist economics, and the resulting impacts on global food security. This study will consider the Brazilian case and aims to construct a conceptual map to serve as the foundation for research conducted within the 'Phoenix - Human Mobility, Global Challenges, and Resilience in an Age of Social Stress' project.

The derived formulas are applied to predict accurate numerical values of the total energies of the ground (bound) $1^{1}S(L = 0)-$states in one-center atomic ions $X^{+} e^{-} e^{-}$ and analogous ground (bound) $1 s σ-$states in the two-center, quasi-adiabatic (or quasi-molecular) $X^{+} X^{+} e^{-}$ ions. We also discuss a few problems which currently remain unsolved for the $Q^{-1}$ expansions constructed for the ground (bound) states in few-electron atoms and ions.

description: When groups of people are represented in classification systems, potential exists for them to be structurally or linguistically subordinated, erased or otherwise misrepresented (Olson & Schlegl, 2001). As Bowker & Star (1999) have shown, the real-world application of classification to people can have legal, economic, medical, social, and educational consequences. The purpose of this research is to contribute to knowledge organization by showing how the epistemological stance underlying specific classificatory discourses interactively participates in the formation of concepts. The medical and legal discourses in three timeframes are examined using Foucauldian genealogical discourse analysis to investigate how their depictions of gender and epistemic foundations correspond and interplay with conceptualizations of similar concepts in four editions of the Dewey Decimal Classification. As knowledge organization research seeks solutions to manage the paradigm change from assumptions of universal knowledge to instability of knowledge, recognition of epistemological underpinnings of classification systems is necessary to understand the very real consequences of corresponding classifications of gender.

Even for the deeply quenched case to low temperatures, we have observed a rapid domain growth; we have proved the efficiency of the exchange Monte Carlo method for the ordering process. The late-stage growth law has been found to be $R(t) \sim t^{1/3}$ for the case of conserved order parameter of three-component system.

description: We give a more precise characterisation of the end of the electroweak phase transition in the framework of the effective 3d SU(2)--Higgs lattice model than has been given before. The model has now been simulated at gauge couplings beta_G=12 and 16 for Higgs masses M_H^*=70, 74, 76 and 80 GeV up to lattices 96^3 and the data have been used for reweighting. The breakdown of finite volume scaling of the Lee-Yang zeroes indicates the change from a first order transition to a crossover at lambda_3/g_3^2=0.102(2) in rough agreement with results of Karsch et al (hep-lat/9608087) at β_G=9 and smaller lattices. The infinite volume extrapolation of the discontinuity Delta < phi^+ phi > /g_3^2 turns out to be zero at lambda_3/g_3^2=0.107(2) being an upper limit. We comment on the limitations of the second method.

description: Novel fermionic quasiparticles with integer pseudospins in some energy bands, such as pseudospin-1 triple-point fermions, recently attract increasing interest since they are beyond the conventional spin-$1/2$ Dirac and Weyl counterparts. In this paper, we propose a class of pseudospin-1 fermioic excitations emerging in topological metal bands, dubbed double-triple-point (DTP) fermions. We first present a general three-band continuum model with $C_4$ symmetry in three dimensions, which has three types of threefold degenerate points in the bands classified by their topological charges $C=\pm4,\pm2,0$, respectively. They are dubbed DTPs as spin-1 generalization of double-Weyl points. We then construct two-dimensional and three-dimensional tight-binding lattice models of topological metal bands with exotic DTP fermions near the DTPs. In two dimensions, the band gaps close at a trivial DTP with zero Berry phase, which occurs at the transition between the normal and topological insulator phases. In three dimensions, the topological properties of three different DTP fermions in lattice systems are further investigated, and the effects of breaking $C_4$ symmetry are also studied, which generally leads to splitting each quadratic DTP into two linear triple points and gives topological phase diagrams. Using ultracold fermionic atoms in optical lattices, the proposed models can be realized and the topological properties of the DTP fermions can be detected.

We give a complete classification of the low-energy properties of the integrable system and introduce a numerical method which allows to study the possible phases of spin ladder systems away from the soluble line in a magnetic field.

description: No abstracts are to be cited without prior reference to the author.The most southern and western herring populations in Europe occur in the Celtic Sea, south of Ireland. These populations are considered to comprise a single stock, although they consist of both autumn and winter spawning components. The herring fishery in this area has been commercially important for many years. Biological sampling has been conducted since the 1920s and routinely since 1958. This study collated and analysed these long‐term data. Overall results were examined in the context of time‐series of environmental data and population scale indices of population status. Size‐at‐age was low in the 1920s and 1950s, but increased to a peak in the 1970s before declining strongly until recently. Currently, growth is increasing again. Condition factors over time declined, whereas growth rates were greater in the 1960s and 1970s than in the 1980s and 1990s. Further analyses suggest that these changes are influenced by environmental factors, especially the North Atlantic Oscillation, sea surface temperature, and the abundance of Calanus copepods. The implications of this work for the rational management of this stock for the future are discussed.

description: Social Virtual Reality based Learning Environments (VRLEs) such as vSocial render instructional content in a three-dimensional immersive computer experience for training youth with learning impediments. There are limited prior works that explored attack vulnerability in VR technology, and hence there is a need for systematic frameworks to quantify risks corresponding to security, privacy, and safety (SPS) threats. The SPS threats can adversely impact the educational user experience and hinder delivery of VRLE content. In this paper, we propose a novel risk assessment framework that utilizes attack trees to calculate a risk score for varied VRLE threats with rate and duration of threats as inputs. We compare the impact of a well-constructed attack tree with an adhoc attack tree to study the trade-offs between overheads in managing attack trees, and the cost of risk mitigation when vulnerabilities are identified. We use a vSocial VRLE testbed in a case study to showcase the effectiveness of our framework and demonstrate how a suitable attack tree formalism can result in a more safer, privacy-preserving and secure VRLE system.

description: Taking the orbital degeneracy of $e_g$ conduction bands and the Coulomb interaction into account in a double-exchange model, we investigate charge dynamics of perovskite Mn oxides by the Lancz$\ddot{\rm o}$s diagonalization method. In the metallic phase near the Mott insulator, it is found that the optical conductivity for a spin-polarized two-dimensional system exhibits a weight transfer to a broad and incoherent structure within the lower-Hubbard band together with a suppressed Drude weight. It reproduces qualitative feature of the experimental results. As an orbital effect, we find that an anomalous charge correlation at quarter filling suppresses the coherent charge dynamics and signals precursor to the charge ordering.

description: Vaccine hesitancy is a significant public health issue globally. We aim to document the barriers toward seasonal influenza vaccine uptake among healthcare workers (HCWs) and pregnant women (PW) in Pakistan. We performed a concurrent mixed methods study in four cities (Karachi, Islamabad, Quetta, and Peshawar) across Pakistan from September to December 2021. The quantitative component consisted of independent cross-sectional surveys for PW and HCWs, and the qualitative component comprised of in-depth interviews (IDIs) and focus group discussions (FGDs) among HCWs. Simple linear regression was used to determine the association of sociodemographic variables with knowledge, attitudes, and practices. Overall, 750 PW and 420 HCWs were enrolled. Among the PW, 44% were willing to receive the vaccine if available free of cost. Only 44% of the HCWs were vaccinated; however, 86% intended to get vaccinated and were willing to recommend the vaccine to their patients. HCWs refused vaccine due to side-effects (65%), cost (57%), and allergies (36%). An education level of secondary school and above was predictive of higher attitude and knowledge scores while having received the COVID-19 vaccine was associated with higher practice scores for both PW and HCWs. Several themes emerged from the interviews: 1) HCWs’ knowledge of influenza and its prevention, 2) HCWs’ perception of motivators and barriers to influenza vaccine uptake and 3) HCWs’ attitudes towrd vaccine promotion. We report low influenza vaccine coverage among HCWs and PW in Pakistan. Educational campaigns addressing misconceptions, and improving affordability and accessibility through government interventions, can improve vaccine uptake.

description: No abstracts are to be cited without prior reference to the author.The European eel (Anguilla anguilla L.) is an endangered species with an important role in the local economies of coastal lagoons. Evaluation of its health is of crucial interest both for fisheriesʹ managers and for conservationists. In the lagoon of Comacchio, northern Italy, trends in the eel fishery have been noted since 1781. A sharp decline has been registered since the 1950s and habitat loss would appear to be the most important factor in this stock collapse. Furthermore, a decline in the economic importance of the fishery has led to a lack of funds for restocking, which constitutes a further threat for the conservation of eels in this region. The eel fishery in Comacchio is carried out in autumn using the lavoriero, V‐shaped permanent trapping weirs located in the canal connecting the lagoon to the sea. Because lavoriero capture the fish during their reproductive migration, we report a large dominance of mature females. A Sustainable Eel Fishery Index (SEELF) for the evaluation of fish condition has been designed using body indices, internal indices, and blood parameters. The SEELF Index has been calculated for a 5‐year sample (as a synthetic parameter for the analysis of the historical trend), to reveal whether or not good fishery practices are being respected. Furthermore, mature female eels migrating towards the open sea from the Comacchio lagoon are less than 10 years old, are not affected by Anguillicola crassus, and, according to biomarker analyses, are not affected by pollution. Thus, we argue that this lagoon is a suitable environment for restocking and for the application of an efficient eel management plan.
Existentially Closed Exponential Fields

description: We characterise the existentially closed models of the theory of exponential fields. They do not form an elementary class, but can be studied using positive logic. We find the amalgamation bases and characterise the types over them. We define a notion of independence and show that independent systems of higher dimension can also be amalgamated. We extend some notions from classification theory to positive logic and position the category of existentially closed exponential fields in the stability hierarchy as NSOP$_1$ but TP$_2$.

description: We discuss BF theories defined on manifolds with spatial boundaries. Variational arguments show that one needs to augment the usual action with a boundary term for specific types of boundary conditions. We also show how to use this procedure to find the boundary actions for theories of gravity with first order formulations. Possible connection with the membrane approach is also discussed.

description: During the rapid deployment of COVID-19 vaccines in 2021, safety concerns may have led some pregnant individuals to postpone vaccination until after giving birth. This study aimed to describe temporal patterns and factors associated with COVID-19 vaccine series initiation after recent pregnancy in Ontario, Canada. Using the provincial birth registry linked with the COVID-19 vaccine database, we identified all individuals who gave birth between January 1 and December 31, 2021, and had not yet been vaccinated by the end of pregnancy, and followed them to June 30, 2022 (follow-up ranged from 6 to 18 months). We used cumulative incidence curves to describe COVID-19 vaccine initiation after pregnancy and assessed associations with sociodemographic, pregnancy-related, and health behavioral factors using Cox proportional hazards regression to estimate adjusted hazard ratios (aHR) and 95% confidence intervals (CI). Among 137,198 individuals who gave birth in 2021, 87,376 (63.7%) remained unvaccinated at the end of pregnancy; of these, 65.0% initiated COVID-19 vaccination by June 30, 2022. Lower maternal age (<25 vs. 30–34 y aHR: 0.73, 95%CI: 0.70–0.77), smoking during pregnancy (vs. nonsmoking aHR: 0.68, 95%CI: 0.65–0.72), lower neighborhood income (lowest quintile vs. highest aHR: 0.79, 95%CI: 0.76–0.83), higher material deprivation (highest quintile vs. lowest aHR: 0.74, 95%CI: 0.70–0.79), and exclusive breastfeeding (vs. other feeding aHR: 0.81, 95%CI: 0.79–0.84) were associated with lower likelihood of vaccine initiation. Among unvaccinated individuals who gave birth in 2021, COVID-19 vaccine initiation after pregnancy reached 65% by June 30, 2022, suggesting persistent issues with vaccine hesitancy and/or access to vaccination in this population.

description: In most existing robust array beam pattern synthesis studies, the bounded-sphere model is used to describe the steering vector (SV) uncertainties. In this letter, instead of bounding the norm of SV perturbations as a whole, we explore the amplitude and phase perturbations of each SV element separately, thereby obtaining a tighter SV uncertainty model. Based on this model, we formulate the robust array pattern synthesis problem from the perspective of the min-max optimization, which aims to minimize the maximum side lobe response, while preserving the main lobe response. However, this problem is difficult due to the infinitely many non-convex constraints. As a remedy, we employ the worst-case criterion and recast the problem as a convex second-order cone program (SOCP). To solve the SOCP, we further develop an alternating direction method of multipliers (ADMM)-based algorithm, which is computationally efficient with each step being computed in closed form. Numerical simulations demonstrate the efficacy and efficiency of the proposed algorithm.

description: (Abridged) The CASA software suite, can now reduce very long baseline interferometry (VLBI) data with the recent addition of a fringe fitter. Here, we present the Radboud PIpeline for the Calibration of high Angular Resolution Data (rPICARD), which is an open-source VLBI calibration and imaging pipeline built on top of the CASA framework. The pipeline is capable of reducing data from different VLBI arrays. It can be run non-interactively after only a few non-default input parameters are set and delivers high-quality calibrated data. CPU scalability based on a message-passing interface (MPI) implementation ensures that large bandwidth data from future arrays can be processed within reasonable computing times. Phase calibration is done with a Schwab-Cotton fringe fit algorithm. For the calibration of residual atmospheric effects, optimal solution intervals are determined based on the signal-to-noise ratio (S/N) of the data for each scan. Different solution intervals can be set for different antennas in the same scan to increase the number of detections in the low S/N regime. These novel techniques allow rPICARD to calibrate data from different arrays, including high-frequency and low-sensitivity arrays. The amplitude calibration is based on standard telescope metadata, and a robust algorithm can solve for atmospheric opacity attenuation in the high-frequency regime. Standard CASA tasks are used for CLEAN imaging and self-calibration. In this work we demonstrate the capabilities of rPICARD by calibrating and imaging 7 mm VLBA data of the central radio source in the M87 galaxy. The reconstructed jet image reveals a complex collimation profile and edge-brightened structure. A potential counter-jet is detected that has 10 % of the brightness of the approaching jet. This constrains jet speeds close to the radio core to about half the speed of light for small inclination angles.

description: We study the impact of anomalous gauge boson and fermion couplings on the production of $W^+W^-$ pairs at potential future LHC upgrades and estimate the sensitivity at $\sqrt{S}=14$ TeV with $3~ab^{-1}$ and $\sqrt{S}=27$ TeV with $15~ab^{-1}$. A general technique for including NLO QCD effects in effective field theory (EFT) fits to kinematic distributions is presented, and numerical results are given for $\sqrt{S}=13$ TeV $W^+W^-$ production. Our method allows fits to anomalous couplings at NLO accuracy in any EFT basis and has been implemented in a publicly available version of the POWHEG-BOX. Analytic expressions for the $K$-factors relevant for $13$ TeV total cross sections are given for the HISZ and Warsaw EFT bases and differential $K$-factors can be obtained using the supplemental material. Our study demonstrates the necessity of including anomalous $Z$- fermion couplings in the extraction of limits on anomalous 3-gauge-boson couplings.

description: We discuss the regimes of quantum degeneracy in a trapped 1D gas and obtain the diagram of states. Three regimes have been identified: the BEC regimes of a true condensate and quasicondensate, and the regime of a trapped gas of Tonks (gas of impenetrable bosons). The presence of a sharp cross-over to the BEC regime requires extremely small interaction between particles. We discuss how to distinguish between true and quasicondensates in phase coherence experiments.
