Self-consistent Effective-one-body theory for spinless binaries based on post-Minkowskian approximation I: Hamiltonian and decoupled equation for $ψ^B_{4}$

description: To build a self-consistent effective-one-body (EOB) theory, in which the Hamiltonian, radiation-reaction force and waveform for the "plus" and "cross" modes of the gravitational wave should be based on the same effective background spacetime, the key step is to look for the decoupled equation for $ψ^B_{4}=\ddot{h}_{+}-i\ddot{h}_{\times}$, which seems a very difficult task because there are non-vanishing tetrad components of the tracefree Ricci tensor for such spacetime. Fortunately, based on an effective spacetime obtained in this paper by using the post-Minkowskian (PM) approximation, we find the decoupled equation for $ψ^B_{4}$ by dividing the perturbation part of the metric into the odd and even parities. With the effective metric and decoupled equation at hand, we set up a frame of self-consistent EOB model for spinless binaries.

description: The problem of attacks on neural networks through input modification (i.e., adversarial examples) has attracted much attention recently. Being relatively easy to generate and hard to detect, these attacks pose a security breach that many suggested defenses try to mitigate. However, the evaluation of the effect of attacks and defenses commonly relies on traditional classification metrics, without adequate adaptation to adversarial scenarios. Most of these metrics are accuracy-based, and therefore may have a limited scope and low distinctive power. Other metrics do not consider the unique characteristics of neural networks functionality, or measure the effect of the attacks indirectly (e.g., through the complexity of their generation). In this paper, we present two metrics which are specifically designed to measure the effect of attacks, or the recovery effect of defenses, on the output of neural networks in multiclass classification tasks. Inspired by the normalized discounted cumulative gain and the reciprocal rank metrics used in information retrieval literature, we treat the neural network predictions as ranked lists of results. Using additional information about the probability of the rank enabled us to define novel metrics that are suited to the task at hand. We evaluate our metrics using various attacks and defenses on a pretrained VGG19 model and the ImageNet dataset. Compared to the common classification metrics, our proposed metrics demonstrate superior informativeness and distinctiveness.

Instent restenosis after carotid stenting: treatment using an off-label cardiac scoring balloon
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Carotid artery stenting (CAS) has emerged as an important alternative to endarterectomy for the management of carotid stenosis [1–3]. Rates of instent restenosis after CAS vary according to literature source and definition of restenosis, ranging from 1% to 21% over 12–18 months, with its treatment dependent on vascular and plaque morphology [4,5]. Treatment of instent restenosis with conventional angioplasty balloons (compliant or noncompliant) caused by circumferential or calcified lesions can be difficult because of inadequate luminal expansion, high dissection rate, and need for repeated revascularization procedures [6–9]. To overcome these obstacles, cutting and scoring balloons have been used in multiple vascular beds in primary stenting for highgrade or concentrically calcified stenosis and for instent restenosis that is refractory to angioplasty with conventional angioplasty balloons

description: We study the inter-particle potentials for few-particle systems in a scalar theory with a non-linear mediating field of the Higgs type. We use the variational method, in a reformulated Hamiltonian formalism of QFT, to derive relativistic three and four particle wave equations for stationary states of these systems. We show that the cubic and quartic non-linear terms modify the attractive Yukawa potentials but do not change the attractive nature of the interaction if the mediating fields are massive.

description: We have investigated effects of the QCD phase transition on the relic GW spectrum applying several equations of state for the strongly interacting matter: Besides the bag model, which describes a first order transition, we use recent data from lattice calculations featuring a crossover. Finally, we include a short period of inflation during the transition which allows for a first order phase transition at finite baryon density. Our results show that the QCD transition imprints a step into the spectrum of GWs. Within the first two scenarios, entropy conservation leads to a step-size determined by the relativistic degrees of freedom before and after the transition. The inflation of the third scenario much stronger attenuates the high-frequency modes: An inflationary model being consistent with observation entails suppression of the spectral energy density by a factor of ~10^(-12).

description: Understanding and mitigating decoherence is a key challenge for quantum science and technology. The main source of decoherence for solid-state spin systems is the uncontrolled spin bath environment. Here, we demonstrate quantum control of a mesoscopic spin bath in diamond at room temperature that is composed of electron spins of substitutional nitrogen impurities. The resulting spin bath dynamics are probed using a single nitrogen-vacancy (NV) centre electron spin as a magnetic field sensor. We exploit the spin bath control to dynamically suppress dephasing of the NV spin by the spin bath. Furthermore, by combining spin bath control with dynamical decoupling, we directly measure the coherence and temporal correlations of different groups of bath spins. These results uncover a new arena for fundamental studies on decoherence and enable novel avenues for spin-based magnetometry and quantum information processing.

description: We analyze the adjoint field inflation in supersymmetric (SUSY) SU(5) model. In minimal SUSY SU(5) hybrid inflation monopoles are produced at the end of inflation. We therefore explore the non-minimal model of inflation based on SUSY SU(5), like shifted hybrid, which provides a natural solution for the monopole problem. We find that the supergravity corrections with non-minimal Kahler potential are crucial to realize the central value of the scalar spectral index n_s ~ 0.96 consistent with the seven year WMAP data. The tensor to scalar ratio r is quite small, taking on values r < 10^{-5}. Due to R-symmetry massless SU(3) octet and SU(2) triplet Higgs bosons are present and could spoil for gauge coupling unification. To keep gauge coupling unification intact, light vector-like particles are added which are expected to be observed at LHC.

description: On conformally compact manifolds of arbitrary signature, we use conformal geometry to identify a natural (and very general) class of canonical boundary problems. It turns out that these encompass and extend aspects of already known holographic bulk-boundary problems, the conformal scattering description of boundary conformal invariants, and corresponding questions surrounding a range of physical bulk wave equations. These problems are then simultaneously solved asymptotically to all orders by a single universal calculus of operators that yields what may be described as a solution generating algebra. The operators involved are canonically determined by the bulk (i.e. interior) conformal structure along with a field which captures the singular scale of the boundary; in particular the calculus is canonical to the structure and involves no coordinate choices. The generic solutions are also produced without recourse to coordinate or other choices, and in all cases we obtain explicit universal formulae for the solutions that apply in all signatures and to a range of fields. A specialisation of this calculus yields holographic formulae for GJMS operators and Branson's Q-curvature.

How the pandemic affected interregional inequality in Russia

description: Analysis of trends in interregional inequality in Russia in 2015–21 and of the actual outcome during the 2020 pandemic and the subsequent recovery in 2021 reveals short-term regional convergence in seven indicators, albeit of different depth and duration. Sub-federal budget revenue experienced the most significant and persistent reduction in interregional disparities, the main sources of which were a reduction of unevenness in a number of taxes, a significant increase in federal transfers and a change in their nature. After a strong short-term convergence, industry, trade, transport and investment all tended to return to long-term divergence paths. Personal income and wage inequality responded weakly to the shock in the short term and entered the new long-term path. Multidirectional spatial trends resulted from the interaction of sectorial and fiscal policy effects during the pandemic.
Just in principle? : assessing the contributions of organic farming to socio-ecological sustainability in Canadian agriculture
Creators: name: Klassen, Susanna Elsie
Publisher: name: University of British Columbia
Year: 2022

description: Agriculture is at the centre of society’s most pressing sustainability challenges, including food insecurity, climate change, ecological degradation, and social inequity. Organic agriculture, when practiced according to an ethic grounded in ecology, health, fairness, and care, has been proposed as a remedy to these challenges. Building on a movement for an alternative to socially and ecologically exploitative food production, organic agriculture is now a multi-billion-dollar industry with established legal and regulatory frameworks around the world. While this growth could be seen as a success, empirical research has called into question the extent to which organic agriculture and market-oriented third-party certifications can foster sustainability transitions and has found that performance is often context dependent (e.g. depending on which practices are adopted). There remain significant gaps in knowledge about how organic agriculture is practiced in jurisdictions around the world relative to the sustainability-related principles on which it was founded, especially the principle of fairness. To address these gaps, I developed a mixed-method assessment grounded in a critical realist methodological approach to evaluate the contributions of organic agriculture to socio-ecological sustainability in Canada. I utilized both qualitative and quantitative methods—drawing from interviews with farmers, inspectors and organic policymakers, analysis of census data for farms across Canada, surveys of vegetable farmers in British Columbia and organic policy documents—to investigate how organic agriculture is shaped and enacted by organic community members at multiple scales. My analysis of organic standards in North America, along with census and survey data in Canada, provide strong evidence for higher levels of adoption of ecologically sustainable management in organic agriculture relative to all other farms. Yet, despite explicit attention to the principle of fairness in organic standards and among organic community actors, I found little evidence that organic agriculture in Canada is correlated with improved working conditions for farmworkers in practice. Across Mexico, the US and Canada, no organic standards contain any requirements related to social sustainability. At the same time, standards governance and community-led efforts toward integrating the principle of fairness into certification show potential to advance a more just and sustainable agriculture.

description: Electrons accelerated on Earth by a rich variety of wave scattering or stochastic processes generate hard non-thermal X-ray bremsstrahlung up to >~ 1 MeV and power Earth's various types of aurorae. Although Jupiter's magnetic field is an order of magnitude larger than Earth's, space-based telescopes have previously detected X-rays only up to ~7 keV. On the basis of theoretical models of the Jovian auroral X-ray production, X-ray emission in the ~2-7 keV band has been interpreted as thermal (arising from electrons characterized by a Maxwell-Boltzmann distribution) bremsstrahlung. Here we report the observation of hard X-rays in the 8-20 keV band from the Jovian aurorae, obtained with the NuSTAR X-ray observatory. The X-rays fit to a flat power-law model with slope 0.60+/-0.22 - a spectral signature of non-thermal, hard X-ray bremsstrahlung. We determine the electron flux and spectral shape in the keV to MeV energy range using coeval in situ measurements by the Juno spacecraft's JADE and JEDI instruments. Jovian electron spectra of the form we observe have previously been interpreted to arise in stochastic acceleration, rather than coherent acceleration by electric fields. We reproduce the X-ray spectral shape and approximate flux observed by NuSTAR, and explain the non-detection of hard X-rays by Ulysses, by simulating the non-thermal population of electrons undergoing precipitating electron energy loss, secondary electron generation and bremsstrahlung emission in a model Jovian atmosphere. The results highlight the similarities between the processes generating hard X-ray auroras on Earth and Jupiter, which may be occurring on Saturn, too.

description: Backdoor attacks impose a new threat in Deep Neural Networks (DNNs), where a backdoor is inserted into the neural network by poisoning the training dataset, misclassifying inputs that contain the adversary trigger. The major challenge for defending against these attacks is that only the attacker knows the secret trigger and the target class. The problem is further exacerbated by the recent introduction of "Hidden Triggers", where the triggers are carefully fused into the input, bypassing detection by human inspection and causing backdoor identification through anomaly detection to fail. To defend against such imperceptible attacks, in this work we systematically analyze how representations, i.e., the set of neuron activations for a given DNN when using the training data as inputs, are affected by backdoor attacks. We propose PiDAn, an algorithm based on coherence optimization purifying the poisoned data. Our analysis shows that representations of poisoned data and authentic data in the target class are still embedded in different linear subspaces, which implies that they show different coherence with some latent spaces. Based on this observation, the proposed PiDAn algorithm learns a sample-wise weight vector to maximize the projected coherence of weighted samples, where we demonstrate that the learned weight vector has a natural "grouping effect" and is distinguishable between authentic data and poisoned data. This enables the systematic detection and mitigation of backdoor attacks. Based on our theoretical analysis and experimental results, we demonstrate the effectiveness of PiDAn in defending against backdoor attacks that use different settings of poisoned samples on GTSRB and ILSVRC2012 datasets. Our PiDAn algorithm can detect more than 90% infected classes and identify 95% poisoned samples.

description: We solve the Killing spinor equations of 6-dimensional (1,0)-supergravity coupled to any number of tensor, vector and scalar multiplets in all cases. The isotropy groups of Killing spinors are $Sp(1)\cdot Sp(1)\ltimes \bH (1)$, $U(1)\cdot Sp(1)\ltimes \bH (2)$, $Sp(1)\ltimes \bH (3,4)$, $Sp(1) (2)$, $U(1) (4)$ and $\{1\} (8)$, where in parenthesis is the number of supersymmetries preserved in each case. If the isotropy group is non-compact, the spacetime admits a parallel null 1-form with respect to a connection with torsion the 3-form field strength of the gravitational multiplet. The associated vector field is Killing and the 3-form is determined in terms of the geometry of spacetime. The $Sp(1)\ltimes \bH$ case admits a descendant solution preserving 3 out of 4 supersymmetries due to the hyperini Killing spinor equation. If the isotropy group is compact, the spacetime admits a natural frame constructed from 1-form spinor bi-linears. In the $Sp(1)$ and U(1) cases, the spacetime admits 3 and 4 parallel 1-forms with respect to the connection with torsion, respectively. The associated vector fields are Killing and under some additional restrictions the spacetime is a principal bundle with fibre a Lorentzian Lie group. The conditions imposed by the Killing spinor equations on all other fields are also determined.

Constructing the US-Mexico border wall (eco)system
Creators: name: Wolf, Gabrielle
Publisher: name: University of British Columbia
Year: 2022

description: In 2019-2020, construction workers contracted to build “Trump’s Wall” between the United States (US) and Mexico bulldozed an estimated thousands of Saguaro cactuses, including within the bounds of Organ Pipe Cactus National Monument (OPCNM), a US National Monument. By way of compensation, US Customs and Border Protection (USCBP, part of Department of Homeland Security DHS) coordinated with National Park Service (NPS) to dig up select Saguaros and to replant them elsewhere in the Monument. Their coordinated attempt brings to attention how non-humans are drawn into border construction and maintenance. As scholars have shown, border militarization is a more-than-human enterprise, one where non-human agencies affect and constitute the material bounds of the nation. This thesis contributes to such scholarship by investigating how the social, material, and ecological geographies of Trump border wall construction are inflected upon by environmental formations (by which I mean more-than-human actors and socio-environmental relationships). With a post-humanist political ecological methodology including interviews, remote ethnography, policy analysis, and GIS / cartography, this project maps out the multiscalar geographies of Trump administration wall construction across the Southwestern borderlands and at the site of OPCNM. Though Trump wall segments mostly replaced existing barriers, their materials effectively fragment Sonoran Desert habitat. In doing so, the wall segments reproduce settler colonial dispossession in the borderlands by inhibiting not only Native peoples (such as the Hia-Ced O’odham) but also their non-human kin from migrating throughout the extent of their ancestral territories. In OPCNM, part of Hia-Ced O’odham ancestral homeland, NPS and DHS’s cooperative attempt to redress some of the immediate ecological consequences of wall construction demonstrates an uneasy interrelationship between the projects of environmental conservation and national securitization. With the Saguaros unlikely to survive transplantation however, that project is contextualized as an extension of border control into the environmental realm. The Saguaro transplant project, as well as the impacts of the diverse coalition of activists who protested wall construction in OPCNM, demonstrate just some of the ways that more-than-human political mutualisms structure the Border Wall (Eco)System.
title: Prediction of driving behavior in cooperative guidance and control: a first game-theoretic approach

description: In this paper, we introduce a novel approach for analyzing the behavior of a vehicle

that is controlled by both a human driver and a cognitive and cooperative automation at the

same time. In a situation where a dynamic and a static obstacle force the driver-vehicle system

to engage in a lane changing maneuver at a sooner or later point in time, the objective is

to maximize the driving comfort, minimize risks, and, ultimately, avoid a crash with either

obstacle. Hereby, the dynamic obstacle is another driver-vehicle system with similar properties

as the first one. Therefore, their interaction can be modeled as a sequential game with imperfect

information, since neither can perfectly predict the behavior of the other. As a proxy for comfort

and safety, we use the time to collision (TTC) and compare it to the preferred TTC of each

system. A further component of the utility function is the velocity, which serves to evaluate

the time consumed to perform a maneuver as well as the costs related to it. Each system

puts different weights on the individual components and, therefore, chooses different actions at

different points in time. It can influence the velocity as well as the lane on which to drive. Using

a simulation, we evaluate the behavior of both systems at several points in time until the static

obstacle is passed.
Global Rigidity of Triangulated Manifolds

description: We prove that if $G$ is the graph of a connected triangulated $(d-1)$-manifold, for $d\geq 3$, then $G$ is generically globally rigid in $\mathbb R^d$ if and only if it is $(d+1)$-connected and, if $d=3$, $G$ is not planar. The special case $d=3$ verifies a conjecture of Connelly. Our results actually apply to a much larger class of simplicial complexes, namely the circuits of the simplicial matroid. We also give two significant applications of our main theorems. We show that that the characterisation of pseudomanifolds with extremal edge numbers given by the Lower Bound Theorem extends to circuits of the simplicial matroid. We also prove the generic case of a conjecture of Kalai concerning the reconstructability of a polytope from its space of stresses. The proofs of our main results adapt earlier ideas of Fogelsanger and Whiteley to the setting of global rigidity. In particular we verify a special case of Whiteley's vertex splitting conjecture for global rigidity.

description: The amount of information exchanged per unit of time between two nodes in a dynamical network or between two data sets is a powerful concept for analysing complex systems. This quantity, known as the mutual information rate (MIR), is calculated from the mutual information, which is rigorously defined only for random systems. Moreover, the definition of mutual information is based on probabilities of significant events. This work offers a simple alternative way to calculate the MIR in dynamical (deterministic) networks or between two data sets (not fully deterministic), and to calculate its upper and lower bounds without having to calculate probabilities, but rather in terms of well known and well defined quantities in dynamical systems. As possible applications of our bounds, we study the relationship between synchronisation and the exchange of information in a system of two coupled maps and in experimental networks of coupled oscillators.

Quantum information in electromagnetism and gravity
Creators: name: DeLisle, Colby L.
Publisher: name: University of British Columbia
Year: 2022

description: The electromagnetic and gravitational fields transfer information between physical systems. This work is an attempt to better understand how matter systems communicate quantum information with one another using these fields, and also how quantum information about matter is broadcast into the fields themselves. We study the former process in Part I and the latter in Part II, by answering two distinct but related questions. Part I of this work studies experimental proposals to observe gravity-induced quantum entanglement between matter systems. If these are successful, it can be argued that they would be the first experimental witness of a quan- tum superposition of space-time geometries, although this interpretation of the proposals has been the subject of vigorous debate. To address this, we first utilize the “quantum action principle” to quantize the electromagnetic and (linearized) gravitational fields. We find that for the quantization to be self-consistent, physical quantum states in the theory must be gauge- and diffeomorphism-invariant. We then show that these constraints are the root cause of the confusion surrounding the proposed gravity-induced en- tanglement experiments. A deeper understanding, however, of how these constraints change when assigning quantum states to different hypersur- faces in space-time provides a satisfying resolution to the debate over the experimental proposals. We conclude that if gravity-induced entanglement is observed, it should be interpreted as experimental evidence in favor of the quantum nature of space-time. Part II then addresses the quantum information content of low energy “soft” radiation. We first show that whether matter particles emit such radiation depends entirely upon the past and future boundaries of the worldlines they follow. This observation explains all tree-level “soft theorems” in both electromagnetism and gravity. We then quantize the electromagnetic and gravitational fields asymptotically, at null infinity. Again, the quantization compels us to ensure physical states are invariant under gauge transforma- tions and diffeomorphisms which persist in the asymptotic limit. Invariance under these “large” transformations fully constrains the state of the leading- order soft radiation, meaning that this radiation cannot carry quantum in- formation. Finally, we illustrate how our construction also avoids infrared divergences when predicting decoherence rates in a model interferometry experiment.
A clarification on the debate on "the original Schwarzschild solution"

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Now that English translations of Schwarzschild's original paper exist, that paper has become accessible to more people. Historically, the so-called "standard Schwarzschild solution" was not the original Schwarzschild's work, but it is actually due to J. Droste and, independently, H. Weyl, while it has been ultimately enabled like correct solution by D. Hilbert. Based on this, there are authors who claim that the work of Hilbert was wrong and that Hilbert's mistake spawned black-holes and the community of theoretical physicists continues to elaborate on this falsehood, with a hostile shouting down of any and all voices challenging them. In this paper we re-analyse "the original Schwarzschild solution" and we show that it is totally equivalent to the solution enabled by Hilbert. Thus, the authors who claim that "the original Schwarzschild solution" implies the non existence of black holes give the wrong answer. We realize that the misunderstanding is due to an erroneous interpretation of the different coordinates. In fact, arches of circumference appear to follow the law dl = rdϕ, if the origin of the coordinate system is a non-dimensional material point in the core of the black-hole, while they do not appear to follow such a law, but to be deformed by the presence of the mass of the central body M if the origin of the coordinate system is the surface of the Schwarzschild sphere.
