description: We propose a highly-scalable method to compute the statistics of charge transfer in driven conductors. The framework can be applied in situations of non-zero temperature, strong coupling to terminals and in the presence of non-periodic light-matter interactions, away from equilibrium. The approach combines the so-called mesoscopic leads formalism with full counting statistics. It results in a generalised quantum master equation that dictates the dynamics of current fluctuations and higher order moments of the probability distribution function of charge exchange. For generic time-dependent quadratic Hamiltonians, we provide closed-form expressions for computing noise in the non-perturbative regime of the parameters of the system, reservoir or system-reservoir interactions. Having access to the full dynamics of the current and its noise, the method allows us to compute the variance of charge transfer over time in non-equilibrium configurations. The dynamics reveal that in driven systems, the average noise should be defined operationally with care over which period of time is covered.

description: Machine Learning approaches are good in solving problems that have less information. In most cases, the software domain problems characterize as a process of learning that depend on the various circumstances and changes accordingly. A predictive model is constructed by using machine learning approaches and classified them into defective and non-defective modules. Machine learning techniques help developers to retrieve useful information after the classification and enable them to analyse data from different perspectives. Machine learning techniques are proven to be useful in terms of software bug prediction. This study used public available data sets of software modules and provides comparative performance analysis of different machine learning techniques for software bug prediction. Results showed most of the machine learning methods performed well on software bug datasets.
Chiral perturbative analysis for an almost massless neutrino in the type-I seesaw mechanism

Year: 2022
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In this paper, we perform chiral perturbative analysis of an approximate lepton number symmetry associated with a sufficiently light neutrino in the type-I seesaw mechanism. For the Dirac mass matrix $m_{D} = (\bm A \, , \bm B \, , \bm C)$, linearly independent components of $\bm C$ from $\bm A$ and $\bm B$ are treated as symmetry-breaking parameters. A deviation in the eigenvector of the massless mode $δ\bm u$ occurs in the first-order perturbation and the lightest mass $m_{1 \, \rm or \, 3} \propto \det m_{D}^{2} / M_{3}$ emerges in the second-order. By solving the perturbation theory, we obtained specific expressions of $δ\bm u$ and $m_{1 \, \rm or \, 3}$. As a result, two complex parameters in $m_{D}$ are bounded to some extent from the eigenvector. These constraints are associated with the chiral symmetry and are not susceptible to renormalization.

Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: This review article presents a summary of the main categories of models developed for modeling cavitation, a multiphase phenomenon in which a fluid locally experiences phase change due to a drop in ambient pressure. The most common approaches to modeling cavitation along with the most common modifications to said approaches due to other effects of cavitating flows are identified and categorized. The application of said categorization is demonstrated through an analysis of selected cavitation models. For each of the models presented, the various assumptions and simplifications made by the authors of the model are discussed, and applications of the model to simulating various aspects of cavitating flow are also presented. The result of the analysis is demonstrated via a visualization of the categorizations of the highlighted models. Using the preceding discussion of the various cavitation models presented, the review concludes with an outlook toward future improvements in the modeling of cavitation.

description: We prove a conjecture which expresses the bigraded Poisson-de Rham homology of the nilpotent cone of a semisimple Lie algebra in terms of the generalized (one-variable) Kostka polynomials, via a formula suggested by Lusztig. This allows us to construct a canonical family of filtrations on the flag variety cohomology, and hence on irreducible representations of the Weyl group, whose Hilbert series are given by the generalized Kostka polynomials. We deduce consequences for the cohomology of all Springer fibers. In particular, this computes the grading on the zeroth Poisson homology of all classical finite W-algebras, as well as the filtration on the zeroth Hochschild homology of all quantum finite W-algebras, and we generalize to all homology degrees. As a consequence, we deduce a conjecture of Proudfoot on symplectic duality, relating in type A the Poisson homology of Slodowy slices to the intersection cohomology of nilpotent orbit closures. In the last section, we give an analogue of our main theorem in the setting of mirabolic D-modules.

description: We identify an optical excitation mechanism that transfers a valley polarization from photo-excited electron-hole pairs to free charge carriers in twisted WSe$_2$/MoSe$_2$ heterobilayers. For small twist angles, the valley lifetimes of the charge carriers are surprisingly short, despite the occurrence of interlayer excitons with their presumably long recombination and polarization lifetimes. For large twist angles, we measure an increase in both the valley polarization and its respective lifetime by more than two orders of magnitude. Interestingly, in such heterobilayers we observe an interlayer transfer of valley polarization from the WSe$_2$ layer into the MoSe$_2$ layer. This mechanism enables the creation of a photo-induced valley polarization of free charge carriers in MoSe$_2$, which amplitude scales with the gate-induced charge carrier density. This is in contrast to monolayer MoSe$_2$, where such a gate-tunable valley polarization cannot be achieved. By combining time-resolved Kerr rotation, photoluminesence and angle-resolved photoemission spectroscopy measurements with first principles calculations, we show that these findings can be explained by twist angle dependent interlayer scattering mechanisms involving the Q- and $Γ$-valleys.

EFFECTS OF ECOSYSTEM STATE CHANGE AND LANDSCAPE VARIABILITY ON SEDIMENT NITRIENT FLUXES
Creators: name: Torano, Olivia Marie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Lake Mattamuskeet, located in North Carolina’s coastal plain, recently underwent a shift in vegetative state. While the west basin of the lake was unvegetated since the early 1990s, the east basin supported dense benthic vegetation until 2014. After vegetation loss in the east basin, the dominant primary producer across both basins became phytoplankton. Sediment and water column nutrient concentrations and transformations were measured between 2016 - 2018 to understand the impact of this primary producer shift on nutrient dynamics. Data collected between 2006 - 2008 were used to investigate long-term trends in nutrient dynamics and controls on denitrification (DNF). Water column nutrient concentrations are low, and have not changed significantly since 2008. Vegetation loss did not result in nutrient efflux from the sediment or inhibit DNF. Managed wetlands have the highest potential for promoting DNF, and management efforts should prioritize minimizing sediment loading, which leads to light attenuation.

description: A measurement of the top quark pair-production cross section in the lepton+jets decay channel is presented. It is based on 4.6 fb$^{-1}$ of $\sqrt{s} = 7$ TeV $pp $ collision data collected during 2011 by the ATLAS experiment at the CERN Large Hadron Collider. A three-class, multidimensional event classifier based on support vector machines is used to differentiate $t\bar{t}$ events from backgrounds. The $t\bar{t}$ production cross section is found to be $σ_{t\bar{t}}=168.5 \pm 0.7$(stat.)$^{+6.2}_{-5.9}$(syst.)$^{+3.4}_{-3.2}$(lumi.) pb. The result is consistent with the Standard Model prediction based on QCD calculations at next-to-next-to-leading order.

description: We perform a systematic symmetry classification of many-body Lindblad superoperators describing general (interacting) open quantum systems coupled to a Markovian environment. Our classification is based on the behavior of the many-body Lindbladian under antiunitary symmetries and unitary involutions. We find that Hermiticity preservation reduces the number of symmetry classes, while trace preservation and complete positivity do not, and that the set of admissible classes depends on the presence of additional unitary symmetries: in their absence or in symmetry sectors containing steady states, many-body Lindbladians belong to one of ten non-Hermitian symmetry classes; if however, there are additional symmetries and we consider non-steady-state sectors, they belong to a different set of 19 classes. In both cases, it does not include classes with Kramer's degeneracy. Remarkably, our classification admits a straightforward generalization to the case of non-Markovian, and even non-trace-preserving, open quantum dynamics. While the abstract classification is completely general, we then apply it to general (long-range, interacting, spatially inhomogeneous) spin-$1/2$ chains. We explicitly build examples in all ten classes of Lindbladians in steady-state sectors, describing standard physical processes such as dephasing, spin injection and absorption, and incoherent hopping, thus illustrating the relevance of our classification for practical physics applications. Finally, we show that the examples in each class display unique random-matrix correlations. To fully resolve all symmetries, we employ the combined analysis of bulk complex spacing ratios and the overlap of eigenvector pairs related by symmetry operations. We further find that statistics of levels constrained onto the real and imaginary axes or close to the origin are not universal due to spontaneous breaking of Lindbladian PT symmetry.

description: Given a projective structure on a surface $N$, we show how to canonically construct a neutral signature Einstein metric with non-zero scalar curvature as well as a symplectic form on the total space $M$ of a certain rank $2$ affine bundle $M \to N$. The Einstein metric has anti-self-dual conformal curvature and admits a parallel field of anti-self-dual planes. We show that locally every such metric arises from our construction unless it is conformally flat. The homogeneous Einstein metric corresponding to the flat projective structure on $\mathbb{RP}^2$ is the non-compact real form of the Fubini-Study metric on $M=\mathrm{SL}(3, \mathrm{R})/\mathrm{GL}(2, \mathrm{R})$. We also show how our construction relates to a certain gauge-theoretic equation introduced by Calderbank.

While the in-plane Poisson's ratios are all positive regardless of their disparate electronic and structural properties, the characteristic interlayer interactions as well as layer stacking structures are shown to determine the sign of their out-of-plane ratios. Thorough investigation of elastic properties as a function of the number of layers for each system is also provided, highlighting their intertwined nature between elastic and electronic properties.

Spatial Resolution Impacts on Deep Convolutional Neural Networks Performance of Land Cover Classification
Creators: name: He, Liu
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Spatial resolution is one of the most significant factors that influence the quality of land cover maps through classification algorithms. So far many geographers directly adapted deep learning neural networks (DCNNs) towards land cover mapping for state-of-the-art accuracy. However, existing studies utilized pre-trained networks and parameters, focused on patch-based classification on very high resolution (VHR) images. The impacts of spatial resolution on classification performance of DCNNs with different structures have not been discussed. In this study, a depth-adaptive deep residual fully convolutional networks (DRFCN) is introduced for wall-to-wall land cover classification in a range of resolutions. Results illustrate: (1) DRFCN achieves outstanding performance than conventional machine learning algorithms. (2) The classification accuracy negatively relates to increasing pixel size. (3) Deep network structure fits classification in relatively coarse resolution, and vice versa. This study will provide a coherent guidance of network design for land cover classification in different resolutions.

For $n$-th order theory of this type, we provide a general receipt for constructing $n$-parameter family of conserved second rank tensors. The family includes the canonical energy-momentum tensor, which is unbounded, while there are bounded conserved tensors that provide classical stability of the system for certain combinations of the parameters in the Lagrangian. We also demonstrate the examples of consistent interactions which are compatible with the requirement of stability.

description: The standard approach to inference from cosmic large-scale structure data employs summary statistics that are compared to analytic models in a Gaussian likelihood with pre-computed covariance. To overcome the idealising assumptions about the form of the likelihood and the complexity of the data inherent to the standard approach, we investigate simulation-based inference (SBI), which learns the likelihood as a probability density parameterised by a neural network. We construct suites of simulated, exactly Gaussian-distributed data vectors for the most recent Kilo-Degree Survey (KiDS) weak gravitational lensing analysis and demonstrate that SBI recovers the full 12-dimensional KiDS posterior distribution with just under $10^4$ simulations. We optimise the simulation strategy by initially covering the parameter space by a hypercube, followed by batches of actively learnt additional points. The data compression in our SBI implementation is robust to suboptimal choices of fiducial parameter values and of data covariance. Together with a fast simulator, SBI is therefore a competitive and more versatile alternative to standard inference.

description: Aging has been associated with a motivational shift to positive over negative information (i.e., positivity effect), which is often explained by a limited future time perspective (FTP) within the framework of socioemotional selectivity theory (SST). However, whether a limited FTP functions similarly in younger and older adults, and whether inter-individual differences in socioemotional functioning are similarly associated with preference for positive information (i.e., positivity) is still not clear. We investigated younger (20–35 years, N = 73) and older (60–75 years, N = 56) adults’ gaze preferences on pairs of happy, angry, sad, and neutral faces using an eye-tracking system. We additionally assessed several parameters potentially underlying inter-individual differences in emotion processing such as FTP, stress, cognitive functioning, social support, emotion regulation, and well-being. While we found no age-related differences in positivity when the entire trial duration was considered, older adults showed longer fixations on the more positive face in later stages of processing (i.e., positivity shifts). This allocation of resources toward more positive stimuli might serve an emotion regulatory purpose and seems consistent with the SST. However, our findings suggest that age moderates the relationship between FTP and positivity shifts, such that the relationship between FTP and positivity preferences was negative in older, and positive in younger adults, potentially stemming from an age-related differential meaning of the FTP construct across age. Furthermore, our exploratory analyses showed that along with the age and FTP interaction, lower levels of worry also played a significant role in positivity shifts. We conclude that positivity effects cannot be solely explained by aging, or the associated reduced FTP per se, but is rather determined by a complex interplay of psychosocial and emotional features.

To illustrate the potential use of our setup, we first introduce VedaWeb, a web-based platform that provides access to ancient Indian texts written in Vedic Sanskrit, the oldest form of ancient Indo-Aryan. Then we describe the C-SALT APIs for Dictionaries (https://api.c-salt.uni-koeln.de/). These APIs make several large Pāli and Sanskrit dictionaries available. Building on that, we present the architecture behind these APIs and finally we summarize by analyzing the potential role of APIs in Digital Humanities projects.
DIAGNOSTIC UNCERTAINTY: EXPLORING PATTERNS OF PATIENT SATISFACTION BY GENDER

description: Clinical uncertainty is known to be a source of dissatisfaction for patients and providers (Calnan1984). My research focuses on diagnostic uncertainty, which takes place when providers struggle to identify and label patients’ symptoms as disease within modern biomedicine. I used 2012 data from the Medical Expenditure Panel Survey (MEPS) to group 5,817 respondents by the diagnostic uncertainty of their medical diagnoses. These groupings were then used to examine the effect of diagnostic uncertainty on patient satisfaction. My findings showed that diagnostic uncertainty was associated with reduced satisfaction with the time patients felt their providers spent with them. There was also evidence of an interaction effect between gender and diagnostic uncertainty, with women reporting dissatisfaction with higher levels of diagnostic uncertainty. Results varied by level of uncertainty and component of satisfaction; therefore, further research exploring the variability of these findings, particularly regarding gender effects across different measures of satisfaction, is needed.

description: Spectroscopy of a Josephson junction device with an embedded quantum dot reveals the presence of a contribution to level splitting in external magnetic field that is proportional to $\cos ϕ$, where $ϕ$ is the gauge-invariant phase difference across the junction. To elucidate the origin of this unanticipated effect, we systematically study the Zeeman splitting of spinful subgap states in the superconducting Anderson impurity model. The magnitude of the splitting is renormalized by the exchange interaction between the local moment and the continuum of Bogoliubov quasiparticles in a variant of the Knight shift phenomenon. The leading term in the shift is linear in the hybridisation strength $Γ$ (quadratic in electron hopping), while the subleading term is quadratic in $Γ$ (quartic in electron hopping) and depends on $ϕ$ due to spin-polarization-dependent corrections to the Josephson energy of the device. The amplitude of the $ϕ$-dependent part is largest for experimentally relevant parameters beyond the perturbative regime where it is investigated using numerical renormalization group calculations. Such magnetic-field-tunable coupling between the quantum dot spin and the Josephson current could find wide use in superconducting spintronics.

The study of triple systems V949 Cen, V358 Pup, and V1055 Sco

description: The systems V949 Cen, V358 Pup, and V1055 Sco are triples comprised of an eclipsing binary orbiting with a distant visual component on a much longer orbit. The first detailed photometric analysis of these interesting systems was performed using also the archival data from Hipparcos, ASAS, SuperWASP, OMC, and Pi Of The Sky surveys. The system V358~Pup was also analysed using the archival ESO spectra and the radial velocities were derived. The analyses of their light curves revealed the physical properties of the eclipsing components, while the interferometric data for these systems obtained during the last century show that the binaries are also weakly gravitationally bounded with the third components on much longer orbits. The photometry was carried out with the robotic telescope FRAM (part of the Pierre Auger Cosmic Ray Observatory), located in Argentina. The BVRI light curves were analysed with the PHOEBE program, yielding the basic physical parameters of the systems and their orbits. V949 Cen and V358 Pup were found to be detached systems, while V1055 Sco is probably a semi-detached one. V358 Pup shows a slow apsidal motion, while for V1055 Sco we detected some period variation probably due to the third body in the system, which cannot easily be attributed to the close visual companion. Therefore, we speculate that V1055 Sco can be a quadruple system. For V949 Cen a new orbit was computed, having the orbital period of about 855 yr.

On energy dissipation in a friction-controlled slide of a body excited by random motions of the foundation

description: We study a friction controlled slide of a body excited by random motions of the foundation it is placed on. Specifically, we are interested in quantities such as displacement, traveled distance, and energy loss due to friction. Assuming that the random excitation is switched off at some time, it is shown that the problem can be treated in an analytic, explicit, manner. Particularly, we derive formulas for the moments of the displacement and distance, and also for the average energy loss. To accomplish that we use the Pugachev-Sveshnikov equation for the characteristic function of a continuous random process given by a system of SDEs. This equation is solved by reduction to a parametric Riemann boundary value problem of complex analysis.

The spontaneous $\mathbb{Z}_2$ breaking Twin Higgs

description: The Twin Higgs model seeks to address the little hierarchy problem by making the Higgs a pseudo-Goldstone of a global $SU(4)$ symmetry that is spontaneously broken to $SU(3)$. Gauge and Yukawa couplings, which explicitly break $SU(4)$, enjoy a discrete $\mathbb{Z}_2$ symmetry that accidentally maintains $SU(4)$ at the quadratic level and therefore keeps the Higgs light. Contrary to most beyond the Standard Model theories, the quadratically divergent corrections to the Higgs mass are cancelled by a mirror sector, which is uncharged under the Standard Model groups. However, the Twin Higgs with an exact $\mathbb{Z}_2$ symmetry leads to equal vevs in the Standard Model and mirror sectors, which is phenomenologically unviable. An explicit $\mathbb{Z}_2$ breaking potential must then be introduced and tuned against the $SU(4)$ breaking terms to produce a hierarchy of vevs between the two sectors. This leads to a moderate but non-negligible tuning. We propose a model to alleviate this tuning, without the need for an explicit $\mathbb{Z}_2$ breaking sector. The model consists of two $SU(4)$ fundamental Higgses, one whose vacuum preserves $\mathbb{Z}_2$ and one whose vacuum breaks it. As the interactions between the two Higgses are turned on, the $\mathbb{Z}_2$ breaking is transmitted from the broken to the unbroken sector and a small hierarchy of vevs is naturally produced. The presence of an effective tadpole and feedback between the two Higgses lead to a sizable improvement of the tuning. The resulting Higgs boson is naturally very Standard Model like.

title: The sustainability of the indigenous banking sector in the Eastern Caribbean: Perspectives and expectations of key external stakeholders
Creators: name: Logie, Aaron
Publisher: name: Edinburgh Napier University
Year: 2023

description: Despite their significant contributions to the economic and social development of the Anglophone Caribbean, their vulnerabilities arising from the distinctive features which limit their ability to withstand financial and economic crises, the indigenous banks in the Eastern Caribbean have received very little attention from academics. This is in sharp contrast to the many studies on banking in larger and more developed economies. This thesis, therefore, aims to fill that gap, and contribute to knowledge and practice, by exploring the sustainability of the relatively small, locally owned, and controlled banks in the Eastern Caribbean, referred to as indigenous banks. This is done from the perspective of their key external stakeholders.

To achieve the aim and objectives, the study purposefully sets out to obtain rich qualitative data from a cross-section of individuals. To guide this approach, a qualitative methodology was adopted using two sample banks. This was supported by semi-structured interviews. The data collected were then analysed using thematic analysis to identify the key features of sustainability and what participants perceived as the critical areas that the banks must strengthen to ensure their long-term survival.

Studying the sustainability of indigenous banks through the views of key external stakeholders provided invaluable insights on ways to promote the long-term survival of these institutions. Two of the foremost recommendations from participants were enhancing the corporate governance practices at the banks and secondly, focusing more on meeting the needs of customers. Other important recommendations included leveraging more on the indigenous identity of the banks, implementing a strategy on consolidation that is acceptable to all stakeholders of the banks, having a proper foreclosure legislation and other supporting institutions such as a credit bureau, and having systems in place to mitigate external threats such as loss of correspondent banking relationships.

These recommendations provide an important perspective, which is by no means the only one, on assessing the long-term sustainability of a business organisation. The advantage is in the fact that the perspective is representative of the views of a broad cross section of stakeholders. These stakeholders include those that purchase the products and services of the banks, those that provide the deposits and capital that finance the operations, those that regulate the activities, and finally those that provide the environment through which the banks can build their brand.

Do open clusters have distinguishable chemical signatures?

description: Past studies have already shown that stars in open clusters are chemically homogeneous (e.g. De Silva et al. 2006, 2007 and 2009). These results support the idea that stars born from the same giant molecular cloud should have the same chemical composition. In this context, the chemical tagging technique was proposed by Freeman & Bland-Hawthorn 2002. The principle is to recover disrupted stellar clusters by looking only to the stellar chemical composition. In order to evaluate the feasibility of this approach, it is necessary to test if we can distinguish between stars born from different molecular clouds. For this purpose, we studied the chemical composition of stars in 32 old and intermediate-age open clusters, and we applied machine learning algorithms to recover the original cluster by only considering the chemical signatures.

description: We revisit the Dirac-Born-Infeld--like boundary counter-term for four dimensional theory of gravity. We show that it correctly executes complete background subtraction for both asymptotically AdS and asymptotically flat geometries. With an appropriate choice of ensemble, we reproduce dyonic black hole thermodynamics with both types of asymptotics by studying local thermodynamics on the cut-off surface.
