A Proposal for Determining the Energy Content of Gravitational Waves by Using Approximate Symmetries of Differential Equations

Year: 2009
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Since gravitational wave spacetimes are time-varying vacuum solutions of Einstein's field equations, there is no unambiguous means to define their energy content. However, Weber and Wheeler had demonstrated that they do impart energy to test particles. There have been various proposals to define the energy content but they have not met with great success. Here we propose a definition using "slightly broken" Noether symmetries. We check whether this definition is physically acceptable. The procedure adopted is to appeal to "approximate symmetries" as defined in Lie analysis and use them in the limit of the exact symmetry holding. A problem is noted with the use of the proposal for plane-fronted gravitational waves. To attain a better understanding of the implications of this proposal we also use an artificially constructed time-varying non-vacuum metric and evaluate its Weyl and stress-energy tensors so as to obtain the gravitational and matter components separately and compare them with the energy content obtained by our proposal. The procedure is also used for cylindrical gravitational wave solutions. The usefulness of the definition is demonstrated by the fact that it leads to a result on whether gravitational waves suffer self-damping.

On the Pion Distribution Amplitude Shape
Creators: name: Polyakov, M. V.
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We argue that the recent BaBar data on $γ\to π$ e.m. transition form factor at large photon virtuality supports the idea that pion distribution amplitude (DA) is close to unity with $ϕ_π^\prime(0)/6\gg 1$ at a normalization point of $μ=0.6÷0.8$ GeV. Such pion DA can be obtained in the effective chiral quark model. The possible flat shape of the pion DA implies that the standard expansion of the DA in Gegenbauer polynomials can be divergent. On basis of chiral models we predict that the two-pion DA should exhibit anomalous endpoint behaviour for pions in the S-wave and that such feature is absent for higher partial waves. The latter implies that the $ρ, f_2$, etc. meson DAs have no anomalous endpoint behaviour. Possible implications of such pion DA for other hard exclusive processes are shortly discussed.

description: We explore a novel mechanism for control of periodicity in persistent current in a twisted normal metal loop threaded by a magnetic flux $ϕ$. A simple tight-binding model is used to describe the system. Quite interestingly we see that, depending on the number of twist $p$, the persistent current exhibits $ϕ_0/p$ ($ϕ_0=ch/e$, the elementary flux-quantum) periodicity. Such fractional periodicity provides a new finding in the study of persistent current.

Breakdown of the isotropy of diffuse radiation as a consequence of its diffraction at multidimensional regular structures

description: This article is devoted to the results of an experimental test of the theoretical assumption that the basic axiomatic postulate of statistical physics according to which it is equally probable for a closed system to reside in any of the microstates accessible to it may be invalid for nonergodic cases. In the course of photometric experiments for the purpose of recording the predicted loss of isotropy by a diffuse light field when it came into contact with a two-dimensional phase-type diffraction grating, a significant deviation from Lambert's law was detected when the diffuse photon gas was scattered by the grating surface. This caused angular anisotropy of the radiation fluxes to appear in the initially homogeneous light field. These results provide a basis for revising the determination of the most probable macrostate of a closed system.

description: Sneutrino-antisneutrino oscillation can be observed at the LHC by studying a charge asymmetry of the leptons in the final states. In this talk, we demonstrate this in the context of an anomaly-mediated supersymmetry breaking model which can give rise to a large oscillation probability. The preferred region of the parameter space is characterized by the presence of a sneutrino next-to-lightest supersymmetric particle and a stau lightest supersymmetric particle. We show that the signals studied here have certain correlations with the pattern of the sneutrino oscillation.

What Counts in Mathematics (and Other) Classrooms? A Framework for Looking at What Matters, and Thoughts About How One Might Use These Ideas for Professional Development
Creators: name: Schoenfeld, Alan H.
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2013

description: This article describes the evolution of an analytical scheme that describes the dimensions of powerful mathematics classrooms-classrooms that produce students who are powerful mathematical thinkers. Such classrooms engage students with coherent and connected mathematics; they provide all students opportunities to do mathematical thinking. They help students develop a sense of mathematical agency and authority, and they employ formative assessment, finding out what students understand and building on those understandings. I discuss how this scheme can be used as the basis for professional development, and how a school district might take up a full-fledged professional development agenda.

description: This poster describes the effort to add a DDI-Codebook (DDI-C) import function into the DDI 4 R package.

The DDI 4 Codebook Group did a lot of the modelling of one section of DDI 4 using a spreadsheet that mapped DDI-C elements into DDI 4 properties. This started with a list of elements used by the Consortium of European Social Science Data Archives (CESSDA) and was refined at the Norway Sprint in Knutholmen in May 2016. Unfortunately, these mappings were not always at the leaf-node level.

An R program also imported DDI-C XML from the European Social Survey and generated a list of unique XPaths of leaf elements used in that set of metadata. These elements, along with corresponding DDI 4 leaf paths, were used to update the spreadsheet.

This spreadsheet has been further refined to create an actionable table mapping DDI-C leaf values to leaf properties in DDI 4. Writing code to import the DDI-C required the following additional information:

	the mapping of DDI-C sub-paths to DDI 4 identifiable classes (e.g., all of the information for one DDI-C var map to one DDI 4 identifiable variable)
	the mapping of abstract target classes to specific extensions
	additional semantic property values, such as type of methodology.

Importing DDI-C into a lifecycle-level version of DDI (e.g., DDI 4) also involves identifying repeated metadata, such as reused value domains (e.g., reused Likertstyle code lists) that are repeated for multiple variables. An R function served to do this sort of matching using the R “all.equal” function, excluding differences in agency, ID and version.
Assessing Modeling
Creators: name: Burkhardt, Hugh
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2013

description: This paper reviews the challenges that higher-level skills present to assessment designers. The discussion is illustrated by exemplar tasks from two Shell Centre projects that emphasize modeling. From the various roles that assessment plays, the analysis starts with summative assessment, describing the multi-dimensional nature of task difficulty involving unfamiliarity, complexity and the degrees of autonomy expected of the student, as well as the technical demand. It distinguishes expert, apprentice, and novice tasks through the lengths of the chains of reasoning they involve and the expertise in mathematical practices they demand. An outline of the design principles for formative assessment that enhances learning includes some “do’s” and “dont's,” leading to a look at future prospects and the strengths and limitations of computer-based assessment.

Mathematical Modeling-The Teacher’s Responsibility
Creators: name: Borromeo Ferri, Rita
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2013

description: Mathematical Modeling has recently become a compulsory part of the Common Core State Standards (CCSS) in the United States. Future teachers must have a strong background about different aspects of modeling and also about appropriate methods for how modeling can be taught. In which ways modeling is the teacher’s responsibility is presented in this paper on the basis of theoretical reflections as well as an in depth focus on more practical experiences and results of empirical studies of pre- and in-service teacher education. Finally a model of necessary teaching competencies for modeling is described in the four dimensions and a conclusion is drawn.

A View of Mathematical Modeling in Mathematics Education
Creators: name: Pollak, Henry
name: Garfunkel, Sol
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2013

description: Mathematical Modeling is being introduced as a new product into the complex system of Mathematics Education. It has to fit with the existing parts and interfaces in this system. As one example, we will consider the effect of mathematical modeling on the transition from secondary to tertiary education. If mathematical modeling is of greater importance to the planners at one of these two levels of education than at the other, then stresses may result. As a second example, we propose to examine changes in teacher education necessitated by the introduction of mathematical modeling at the secondary level. Ideally, one might wish to prepare teachers to teach mathematical modeling by concentrating purely on modeling without the distraction of new mathematical ideas, but it is not clear that this can always be done. Finally, we plan to make some comments on the effect of mathematical modeling has on the relationship between mathematics education and mathematics itself. Each of these should gain from cooperation with the other.

description: Since SARS-CoV-2 started spreading in Europe in early 2020, there has been a strong call for technical solutions to combat or contain the pandemic, with contact tracing apps at the heart of the debates. The EU's General Data Protection Regulation (GDPR) requires controllers to carry out a data protection impact assessment (DPIA) where their data processing is likely to result in a high risk to the rights and freedoms (Art. 35 GDPR). A DPIA is a structured risk analysis that identifies and evaluates possible consequences of data processing relevant to fundamental rights in advance and describes the measures envisaged to address these risks or expresses the inability to do so. Based on the Standard Data Protection Model (SDM), we present the results of a scientific and methodologically clear DPIA of the German German Corona-Warn-App (CWA). It shows that even a decentralized architecture involves numerous serious weaknesses and risks, including larger ones still left unaddressed in current implementations. It also found that none of the proposed designs operates on anonymous data or ensures proper anonymisation. It also showed that informed consent would not be a legitimate legal ground for the processing. For all points where data subjects' rights are still not sufficiently safeguarded, we briefly outline solutions.

Social order in the age of artificial intelligence : the use of technology in migration governance and decision-making
Creators: name: Vohra, Apurva
Publisher: name: University of British Columbia
Year: 2023

description: Artificial Intelligence (AI) and untested technologies such as facial recognition, aerial surveillance drones, biometrics and automated decision making tools are increasingly being used by states and international organizations to control and regulate migration. The purpose of this research is to understand why the international migration regime overlooks overt manifestations of racial discrimination against migrants while sanctioning the use of untested technologies they are subjected to. In order to study the use of AI and related technologies, this research assesses two case studies in which technological tools are deployed by United Nations High Commissioner for Refugees and Canada for migration management. The case studies found that in the absence of accountability and oversight the use of these technological solutions leads to the violation of privacy rights of the subjects, discrimination, and raises concerns about transparency and vulnerability. Moreover, there is a stark power imbalance between the migrants on one hand and states and international organisations that employ these AI technologies on the other hand as the migrants are subjected to these technologies without their active consent and any possibility for recourse. Consequently, migrants have become involuntary experimental subjects of these technologies. The research aims to make three contributions: First, the project maps the terrain of the international migration regime by demonstrating the use of untested technologies on migrants without any regard to their rights and in the absence of any oversight. Second, the project articulates a new analytical framework informed by perspectives from Critical Race Theory, Third World Approaches to International Law and Critical Technological Studies to decipher how the foundational inequality inherent in the migration regime is replicated by the use of these technologies. Moreover, the migrants’ lack of agency and consent related to the use of these technological tools magnifies broader dynamics of inequality. Third, the project makes a normative claim that race-literate and race-conscious technological designs (as opposed to race-neutral ones) will train the algorithms to avoid their propensity of replicating racial inequalities by capturing diverse cultural and social contexts without introducing bias into the technologies.

description: We quantify the evolution of the spiral, S0 and elliptical fractions in galaxy clusters as a function of cluster velocity dispersion ($σ$) and X-ray luminosity ($L_X$) using a new database of 72 nearby clusters from the WIde-Field Nearby Galaxy-cluster Survey (WINGS) combined with literature data at $z=0.5-1.2$. Most WINGS clusters have $σ$ between 500 and 1100 $\rm km s^{-1}$, and $L_X$ between 0.2 and $5 \times 10^{44} \rm erg/s$. The S0 fraction in clusters is known to increase with time at the expense of the spiral population. We find that the spiral and S0 fractions have evolved more strongly in lower $σ$, less massive clusters, while we confirm that the proportion of ellipticals has remained unchanged. Our results demonstrate that morphological evolution since $z=1$ is not confined to massive clusters, but is actually more pronounced in low mass clusters, and therefore must originate either from secular (intrinsic) evolution and/or from environmental mechanisms that act preferentially in low-mass environments, or both in low- and high-mass systems. We also find that the evolution of the spiral fraction perfectly mirrors the evolution of the fraction of star-forming galaxies. Interestingly, at low-z the spiral fraction anticorrelates with $L_X$. Conversely, no correlation is observed with $σ$. Given that both $σ$ and $L_X$ are tracers of the cluster mass, these results pose a challenge for current scenarios of morphological evolution in clusters.

description: Exercise induces many health benefits, preventing or treating diseases. On the other hand, the intestine houses trillions of microbes with the ability to influence the normal physiology of the organism. The intestinal microbiota is immensely diverse, varies between individuals, and can fluctuate according to various factors, including physical activity. In this sense, the aim of this systematic review is to search through the recent knowledge, in order to elucidate the roles played by different exercise modalities on modulation of the intestinal microbiota of adults. A literature search was performed in the PubMed, SCOPUS and Web of Science databases. The main inclusion criteria were randomised controlled trials involving exercise and microbiota in adults. The initial search identified 1,103 publications of which 13 were finally included. The heterogeneity of the training parameters used in the studies, statistical analyses, and sequencing methods did not allow us to carry out a meta-analysis. However, the results tend to show that modulation of the gut microbiome is related to the type of exercise, the intensity and the time of intervention, where these changes are more significant at the level of specific microbial populations than richness and diversity indices.

description: In this paper we describe an original computational model for solving different types of Distributed Constraint Satisfaction Problems (DCSP). The proposed model is called Controller-Agents for Constraints Solving (CACS). This model is intended to be used which is an emerged field from the integration between two paradigms of different nature: Multi-Agent Systems (MAS) and the Constraint Satisfaction Problem paradigm (CSP) where all constraints are treated in central manner as a black-box. This model allows grouping constraints to form a subset that will be treated together as a local problem inside the controller. Using this model allows also handling non-binary constraints easily and directly so that no translating of constraints into binary ones is needed. This paper presents the implementation outlines of a prototype of DCSP solver, its usage methodology and overview of the CACS application for timetabling problems.

description: In this paper we describe Routhian reduction as a special case of standard symplectic reduction, also called Marsden-Weinstein reduction. We use this correspondence to present a generalization of Routhian reduction for quasi-invariant Lagrangians, i.e. Lagrangians that are invariant up to a total time derivative. We show how functional Routhian reduction can be seen as a particular instance of reduction of a quasi-invariant Lagrangian, and we exhibit a Routhian reduction procedure for the special case of Lagrangians with quasi-cyclic coordinates. As an application we consider the dynamics of a charged particle in a magnetic field.

Incremental learning and federated learning for heterogeneous medical image analysis
Creators: name: Ayromlou, Sana
Publisher: name: University of British Columbia

description: Standard deep learning paradigm may not be practical over real-world heterogeneous medical data, where new disease merges over time with data acquired in a distributed manner across various hospitals. There have been approaches to facilitate the training of deep models over two primary categories of heterogeneity, including 1) class incremental learning, which offers a promising solution for sequential heterogeneity by adapting a deep network trained on previous disease classes to handle newly introduced diseases over time; 2) federated learning, which offers a promising solution for distributed heterogeneity, by training a global model on a centralized server over private datasets of various hospitals or clients without requiring them to share data. The core challenge in both approaches is catastrophic forgetting, which refers to performance degradation on previously trained data when adapting a model to available data. Due to strict patient privacy regulations, storing and sharing medical data are often discouraged, posing a significant hurdle in addressing such a forgetting. We propose to leverage medical data synthesis to recover inaccessible medical data in heterogeneous learning, presenting two distinctive novel frameworks. Our first framework introduces a novel two-step, data-free class incremental learning pipeline. Initially, it synthesizes data by inverting trained model weights on previous classes and matching statistics saved in continual normalization layers to obtain continual class-specific samples. Subsequently, the model is updated by incorporating three novel loss functions to enhance the utility of synthesized data and mitigate forgetting. Extensive experiments demonstrate that the proposed framework achieves comparative results with state-of-the-art methods on four public MedMNIST datasets and an in-house heart echocardiography dataset. We propose our second framework as a novel federated learning approach to mitigate forgetting by generating and utilizing united global synthetic data among clients. First, we proposed constrained model inversion over the server model to enforce an information-preserving property in synthetic data and leverage the global distribution captured in the globally aggregated server model. Then, we utilize this synthetic data alongside the local data to enhance the generalization capabilities of local training. Extensive experiments show that the proposed method achieves state-of-the-art performance on the BloodMNIST and Retina datasets.

description: The effects of surface chemical doping on spin transport in graphene are investigated by performing non-local measurements in ultrahigh vacuum while depositing gold adsorbates. We demonstrate manipulation of the gate-dependent non-local spin signal as a function of gold coverage. We discover that charged impurity scattering is not the dominant mechanism for spin relaxation in graphene, despite its importance for momentum scattering. Finally, unexpected enhancements of the spin lifetime illustrate the complex nature of spin relaxation in graphene.

Strengthening a Country by Building a Strong Public School Teaching Profession

description: What would be one of the most sensible ways for a country to invest to achieve maximal economic growth? A recent study (Chetty, Friedman, & Rockoff, 2011) by economists at Harvard and Columbia Universities shows that better teacher quality results in significantly higher students’ lifetime earnings. And investing in public school teachers results in an expanding skilled work force, the foundation for maximal economic growth. Although Japan’s economic growth has declined in recent decades, Japan has been and still is one of the several countries successfully educating students to participate in a large, highly skilled work force that generates a high per capita GDP. In this paper, characteristics of Japanese public schools that have contributed to attracting and retaining superior teachers will be described from the perspective of a high school mathematics teacher with 20 years teaching experience in Japanese public high schools and more than 13 years teaching in the United States; and more recently as department chairperson, hiring mathematics teachers for a private, residential high school. The paper will explore how better to select teachers with reference to actual practice in Japan and in the US and will include an analysis of actual qualifying/employment examinations and their outcomes. Prospects to foster and maintain a top tier, public school teaching profession that will expand the high skilled population and counteract “brain drain” for a developing country will be discussed.

description: The purpose of this article is to present five examples of teacher leadership from within secondary mathematics classrooms. These vignettes come from a larger study that resulted in a teacher leader continuum. This article offers classroom teacher examples that highlight each of five positions along that continuum. The argument is made that a wide array of secondary mathematics teacher leaders are needed to improve the teaching and learning of mathematics for all students.

description: Leaders in mathematics are responsible for implementing positive change within their school districts and motivating teachers of mathematics to improve their practices. One way mathematics leaders can achieve this goal is by establishing professional collaborations. We analyzed the research and summarized the common attributes found in successful professional collaborations into a research-based framework we present as the COTEAMS framework. Using this framework, mathematics leaders can empower teachers and provide the necessary support for them to participate successfully in professional collaborations.

description: The description of the inspiral of a stellar-mass compact object into a massive black hole sitting at a galactic centre is a problem of major relevance for the future space-based gravitational-wave observatory LISA (Laser Interferometer Space Antenna), as the signals from these systems will be buried in the data stream and accurate gravitational-wave templates will be needed to extract them. The main difficulty in describing these systems lies in the estimation of the gravitational effects of the stellar-mass compact object on his own trajectory around the massive black hole, which can be modeled as the action of a local force, the self-force. In this paper, we present a new time-domain numerical method for the computation of the self-force in a simplified model consisting of a charged scalar particle orbiting a nonrotating black hole. We use a multi-domain framework in such a way that the particle is located at the interface between two domains so that the presence of the particle and its physical effects appear only through appropriate boundary conditions. In this way we eliminate completely the presence of a small length scale associated with the need of resolving the particle. This technique also avoids the problems associated with the impact of a low differentiability of the solution in the accuracy of the numerical computations. The spatial discretization of the field equations is done by using the pseudospectral collocation method and the time evolution, based on the method of lines, uses a Runge-Kutta solver. We show how this special framework can provide very efficient and accurate computations in the time domain, which makes the technique amenable for the intensive computations required in the astrophysically-relevant scenarios for LISA.

An Ultracool Star's Candidate Planet

description: We report here the discovery of the first planet around an ultracool dwarf star. It is also the first extrasolar giant planet (EGP) astrometrically discovered around a main-sequence star. The statistical significance of the detection is shown in two ways. First, there is a 2 x 10^-8 probability that the astrometric motion fits a parallax-and-proper-motion-only model. Second, periodogram analysis shows a false alarm probability of 3 x 10^-5 that the discovered period is randomly generated. The planetary mass is M2 = 6.4 (+2.6,-3.1) Jupiter-masses (MJ), and the orbital period is P = 0.744 (+0.013,-0.008) yr in the most likely model. In less likely models, companion masses that are higher than the 13 MJ planetary mass limit are ruled out by past radial velocity measurements unless the system radial velocity is more than twice the current upper limits and the near-periastron orbital phase was never observed. This new planetary system is remarkable, in part, because its star, VB 10, is near the lower mass limit for a star. Our astrometric observations provide a dynamical mass measurement and will in time allow us to confront the theoretical models of formation and evolution of such systems and their members. We thus add to the diversity of planetary systems and to the small number of known M-dwarf planets. Planets such as VB 10b could be the most numerous type of planets because M stars comprise >70% of all stars. To date they have remained hidden since the dominant radial-velocity (RV) planet-discovery technique is relatively insensitive to these dim, red systems.
