description: Radiation containment systems within spacecraft equipped with nuclear reactors are indispensable for ensuring the safety of astronauts and the success of space missions. These systems play a crucial role in minimizing radiation exposure to crew members and vital spacecraft components. The assessment of these systems' efficiency and effectiveness often employs the Overall Equipment Effectiveness (OEE) metric, considering Availability, Performance, and Quality as key parameters. Availability measures system uptime, Performance evaluates its shielding capabilities, and Quality assesses its integrity. This article explores the critical importance of radiation containment systems in space missions, their evaluation through the OEE metric, and the utilization of experimental designs to optimize their performance. Additionally, it highlights the significance of charged particle detectors in monitoring and mitigating radiation risks. The ultimate goal is to ensure the safety and success of crewed space missions involving nuclear reactors, emphasizing the need for continuous advancements in radiation containment technology.

 

Strahlenschutzsysteme in Raumfahrzeugen, die mit Kernreaktoren ausgestattet sind, sind für die Gewährleistung der Sicherheit von Astronauten und den Erfolg von Weltraummissionen unverzichtbar. Diese Systeme spielen eine entscheidende Rolle bei der Minimierung der Strahlenbelastung von Besatzungsmitgliedern und lebenswichtigen Komponenten von Raumfahrzeugen. Zur Bewertung der Effizienz und Effektivität dieser Systeme wird häufig die Gesamtanlageneffektivität (Overall Equipment Effectiveness, OEE) herangezogen, wobei Verfügbarkeit, Leistung und Qualität als Schlüsselparameter berücksichtigt werden. Die Verfügbarkeit misst die Betriebszeit des Systems, die Leistung bewertet seine Abschirmfähigkeiten und die Qualität bewertet seine Integrität. Dieser Artikel untersucht die entscheidende Bedeutung von Strahlenschutzsystemen bei Weltraummissionen, ihre Bewertung anhand der OEE-Metrik und die Nutzung experimenteller Designs zur Optimierung ihrer Leistung. Darüber hinaus wird die Bedeutung von Detektoren für geladene Teilchen bei der Überwachung und Minderung von Strahlungsrisiken hervorgehoben. Das ultimative Ziel besteht darin, die Sicherheit und den Erfolg bemannter Weltraummissionen mit Kernreaktoren zu gewährleisten und dabei die Notwendigkeit kontinuierlicher Fortschritte in der Technologie zur Strahleneindämmung hervorzuheben.

description: A hermitian matrix can be parametrized by a set consisting of its determinant and the eigenvalues of its submatrices. We established a group of equations which connect these variables with the mixing parameters of diagonalization. These equations are simple in structure and manifestly invariant in form under the symmetry operations of dilatation, translation, rephasing and permutation. When applied to the problem of neutrino oscillation in matter they produced two new ``matter invariants" which are confirmed by available data.

Online Algorithms for Hierarchical Inference in Deep Learning applications at the Edge

description: We consider a resource-constrained Edge Device (ED), such as an IoT sensor or a microcontroller unit, embedded with a small-size ML model (S-ML) for a generic classification application and an Edge Server (ES) that hosts a large-size ML model (L-ML). Since the inference accuracy of S-ML is lower than that of the L-ML, offloading all the data samples to the ES results in high inference accuracy, but it defeats the purpose of embedding S-ML on the ED and deprives the benefits of reduced latency, bandwidth savings, and energy efficiency of doing local inference. In order to get the best out of both worlds, i.e., the benefits of doing inference on the ED and the benefits of doing inference on ES, we explore the idea of Hierarchical Inference (HI), wherein S-ML inference is only accepted when it is correct, otherwise the data sample is offloaded for L-ML inference. However, the ideal implementation of HI is infeasible as the correctness of the S-ML inference is not known to the ED. We propose an online meta-learning framework that the ED can use to predict the correctness of the S-ML inference. In particular, we propose to use the maximum softmax value output by S-ML for a data sample and decide whether to offload it or not. The resulting online learning problem turns out to be a Prediction with Expert Advice (PEA) problem with continuous expert space. We propose two different algorithms and prove sublinear regret bounds for them without any assumption on the smoothness of the loss function. We evaluate and benchmark the performance of the proposed algorithms for image classification application using four datasets, namely, Imagenette and Imagewoof, MNIST, and CIFAR-10.

description: We propose new $G_2$-holonomy manifolds, which geometrize the Gaiotto-Kim 4d N=1 duality domain walls of 5d N=1 theories. These domain walls interpolate between different extended Coulomb branch phases of a given 5d superconformal field theory. Our starting point is the geometric realization of such a 5d superconformal field theory and its extended Coulomb branch in terms of M-theory on a non-compact singular Calabi-Yau three-fold and its Kähler cone. We construct the 7-manifold that realizes the domain wall in M-theory by fibering the Calabi-Yau three-fold over a real line, whilst varying its Kähler parameters as prescribed by the domain wall construction. In particular this requires the Calabi-Yau fiber to pass through a canonical singularity at the locus of the domain wall. Due to the 4d N=1 supersymmetry that is preserved on the domain wall, we expect the resulting 7-manifold to have holonomy $G_2$. Indeed, for simple domain wall theories, this construction results in 7-manifolds, which are known to admit torsion-free $G_2$-holonomy metrics. We develop several generalizations to new 7-manifolds, which realize domain walls in 5d SQCD theories and walls between 5d theories which are UV-dual.

description: The latest large language models (LLMs) such as ChatGPT, exhibit strong capabilities in automated mental health analysis. However, existing relevant studies bear several limitations, including inadequate evaluations, lack of prompting strategies, and ignorance of exploring LLMs for explainability. To bridge these gaps, we comprehensively evaluate the mental health analysis and emotional reasoning ability of LLMs on 11 datasets across 5 tasks. We explore the effects of different prompting strategies with unsupervised and distantly supervised emotional information. Based on these prompts, we explore LLMs for interpretable mental health analysis by instructing them to generate explanations for each of their decisions. We convey strict human evaluations to assess the quality of the generated explanations, leading to a novel dataset with 163 human-assessed explanations. We benchmark existing automatic evaluation metrics on this dataset to guide future related works. According to the results, ChatGPT shows strong in-context learning ability but still has a significant gap with advanced task-specific methods. Careful prompt engineering with emotional cues and expert-written few-shot examples can also effectively improve performance on mental health analysis. In addition, ChatGPT generates explanations that approach human performance, showing its great potential in explainable mental health analysis.

description: The Sloan Digital Sky Survey (SDSS) and photometric/spectroscopic surveys in the GOODS-South field (the Chandra Deep Field-South, CDFS) are used to construct volume-limited, stellar mass-selected samples of galaxies at redshifts 02.5. The fraction of E+S0 galaxies is 43+/-3%$ at z~0.03 and 48+/-7% at z~0.8, i.e., it has not changed significantly since z~0.8. When combined with recent results for cluster galaxies in the same redshift range, we find that the morphology-density relation for galaxies more massive than 0.5M* has remained constant since at least z~0.8. This implies that galaxies evolve in mass, morphology and density such that the morphology-density relation does not change. In particular, the decline of star formation activity and the accompanying increase in the stellar mass density of red galaxies since z~1 must happen without large changes in the early-type galaxy fraction in a given environment.

A defence of Kuhn's incommensurability thesis
Creators: name: Kosub, Timothy Alexander
Publisher: name: University of British Columbia
Year: 2010

description: Kuhn's incommensurability thesis is the claim that successive scientific theories often conflict not only logically but also normatively: i.e. they differ both about nature and also about the use of common apparatus, concepts and experimental results, and what are proper scientific goals and methods. Critics commonly object that Kuhn's thesis attacks such traditional scientific values as objectivity and rationality. But their strongest response can be expressed as a dilemma: either, if taken literally, the incommensurability thesis is self-contradictory; or, if that literal reading is rejected, this thesis has no philosophical Import. Kuhn claims his critics have misinterpreted his thesis and he maintains both its intelligibility and relevance. The problem is whether his position can be sustained. In support of Kuhn, I argue that his critics' reading of his thesis is based on a mistaken Identification of logic with formal logic and, more generally, of comparability with commensurabil-lty. I argue that logical comparison of theories that lack common concepts is possible if one can compare theories directly, as whole to whole, and that such direct logical comparison is actually commonplace in natural languages. I also argue more generally that Kuhn's critics' identification of comparison with com-mensuration leads to a vicious regress. My attempt at resolving the dispute between Kuhn and his critics is informed by a simple "hermeneutic" principle: If one view seems either unintelligible or irrelevant to the other, then both sides probably disagree on the Interpretation of shared concepts. Once the focus of the dispute is located, arguments can often be given for preferring one interpretation over another. Thus if I am right that Kuhn's critics' view wrongly equates comparability with commensurability and logic with formal logic, that view clearly must be replaced by one that distinguishes them. I argue that if those distinctions are made, incommensurability can be seen to represent no essential threat to scientific rationality and objectivity. In this light, I suggest Kuhn's major analytic concepts be viewed as Improvements on more traditional notions drawn from formal logic. I also use a historical case study of the original discovery of geometrical incommensurability to illustrate further Kuhn's concepts and to develop a more general notion of a proof of incommensurability that is applicable to scientific theories.

description: This work aims to develop a computationally inexpensive approach, based on machine learning techniques, to accurately predict thousands of stellar rotation periods. The innovation in our approach is the use of the XGBoost algorithm to predict the rotation periods of Kepler targets by means of regression analysis. Therefore, we focused on building a robust supervised machine learning model to predict surface stellar rotation periods from structured data sets built from the Kepler catalogue of K and M stars. We analysed the set of independent variables extracted from Kepler light curves and investigated the relationships between them and the ground truth. Using the extreme gradient boosting method, we obtained a minimal set of variables that can be used to build machine learning models for predicting stellar rotation periods. Our models are validated by predicting the rotation periods of about 2900 stars. The results are compatible with those obtained by classical techniques and comparable to those obtained by other recent machine learning approaches, with the advantage of using much fewer predictors. Restricting the analysis to stars with rotation periods of less than 45 days, our models are on average 96 % correct. We have developed an innovative approach, based on a machine learning method, to accurately fit the rotation periods of stars. Based on the results of this study, we conclude that the best models generated by the proposed methodology are competitive with the state-of-the-art approaches, with the advantage of being computationally cheaper, easy to train, and relying on small sets of predictors.

Canada and U.S. public policy on aboriginal land claims 1960-1988 : Alaska and British Columbia compared
Creators: name: Bryant, Michael J.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis provides a comparison of the public policy outcomes in Alaska and B.C. in the area of native land claims. In both Canada and the United States, native land claims are filed by aboriginal groups seeking recognition of aboriginal title, and/or compensation for land taken by the state. The goal of an aboriginal group making a land claim is to achieve settlement with the state. For both nations, settlement has historically meant anything from the trading of beads and blankets for huge tracts of land, through the allocation of millions to billions of dollars to aboriginal peoples, to elaborate profit-sharing schemes between natives and industry. American Indians have been more successful, compared with their Canadian brethren, in achieving fair settlements over time. Alaska and British Columbia provide two contemporary examples of this phenomenon: in Alaska, the native people achieved settlement for their enormous land claim in 1972; in British Columbia, 19 native land claims, filed since 1976, remain stagnant as the governments of Canada and British Columbia refuse to negotiate a settlement with Canadian aboriginals. Why was there settlement in Alaska, while in B.C. there appears no settlement in sight.? The goal of the thesis is to provide an explanation as to why the policy outcomes in British Columbia and Alaska are divergent. The method of investigation involves the testing of a series of "independent variables" -- public opinion, environment, pluralism, statism, and structural marxism -- that explain policy outcomes. Each explanation will be measured for its significance, and will be ranked at the end of the thesis in terms of its importance in explaining the "dependent variable", or policy outcome. The results of the comparison offer a primarily structural marxist argument, with interrelated statist concerns also playing a pivotal role in the final policy outcome. This thesis argues that, in explaining the divergence in Canadian and American policies concerning aboriginal land claims, the interests of business and state actors transcend institutional constraints, as well as non-political and cultural forces. Nonetheless, the significant native population in Alaska, together with the Alaskan native political efforts, serve as important causes of the policy outcome. One finds that state action by governmental actors, together with the state's protection of the capitalist interest, led to the settlement of native land claims in Alaska. These ingredients are absent in British Columbia, thereby explaining the divergent Canadian policy which rejects the settlement of the 19 outstanding B.C. native land claims filed since 1976.

description: Subsystem quantum error-correcting codes typically involve measuring a sequence of non-commuting parity check operators. They can sometimes exhibit greater fault-tolerance than conventional subspace codes, which use commuting checks. However, unlike subspace codes, it is unclear if subsystem codes -- in particular their advantages -- can be understood in terms of ground state properties of a physical Hamiltonian. In this paper, we address this question for the three-dimensional subsystem toric code (3D STC), as recently constructed by Kubica and Vasmer [Nat. Comm. 13, 6272(2022)], which exhibits single-shot error correction (SSEC). Motivated by a conjectured relation between SSEC and thermal stability, we study the zero and finite temperature phases of an associated non-commuting Hamiltonian. By mapping the Hamiltonian model to a pair of 3D Z_2 gauge theories coupled by a kinetic constraint, we find various phases at zero temperature, all separated by first-order transitions: there are 3D toric code-like phases with deconfined point-like excitations in the bulk, and there are phases with a confined bulk supporting a 2D toric code on the surface when appropriate boundary conditions are chosen. The latter is similar to the surface topological order present in 3D STC. However, the similarities between the SSEC in 3D STC and the confined phases are only partial: they share the same sets of degrees of freedom, but they are governed by different dynamical rules. Instead, we argue that the process of SSEC can more suitably be associated with a path (rather than a point) in the zero-temperature phase diagram, a perspective which inspires alternative measurement sequences enabling SSEC. Moreover, since none of the above-mentioned phases survives at nonzero temperature, SSEC of the code does not imply thermal stability of the associated Hamiltonian phase.

description: The novel Gaia Multi Peak (GMP) technique has proven to be able to successfully select dual and lensed AGN candidates at sub-arcsec separations. Both populations are important because dual AGN represent one of the central, still largely untested, predictions of lamdaCDM cosmology, and compact lensed quasars allow to probe the central regions of the lensing galaxies. In this work, we present high spatial resolution spectroscopy of twelve GMP-selected systems. We use the the adaptive-optics assisted integral-field spectrograph MUSE at VLT to resolve each system and study the nature of each component. All the targets reveal the presence of two components confirming the GMP selection. We classify five targets as dual AGN, two as lensed systems, and five as a chance alignment of a star and and AGN. Having separations between 0.30" and 0.86", these dual and lensed systems are, to date, among the most compact ever discovered at z >0.3. This is the largest sample of distant dual AGN with sub-arcsec separations ever presented in a single paper.

Oxypoda demissa appears to be a hygrophilous species associated with wet habitats of various kinds. In New Brunswick, adults were captured in moist leaf litter on the margin of a vernal pond in a mixed forest, among leaves and sedges on pond margin, in moist grass litter and sphagnum in Carex marsh, among sedges along margin of small spring-fed brook in a mature hardwood forest and among leaf litter and grass on hummocks in a wet alder (Alnus sp.) swamp. In Nova Scotia, this species was reported from litter of Alnus clumps (Klimaszewski et al. 2006). A number of adults were collected with a net during late afternoon (15:00 to 18:00 h) flights. Adults were captured in April, May, June, and July. Collection method: sifting, some collected in flight with net during evening. Distribution in Canada and Alaska.

An Empirical Study of Fault Localization in Python Programs
Creators: name: Rezaalipour, Mohammad

Publisher: name: arXiv
Year: 2023
Subjects: subject: Software Engineering (cs.SE)
subject: FOS: Computer and information sciences

description: Despite its massive popularity as a programming language, especially in novel domains like data science programs, there is comparatively little research about fault localization that targets Python. Even though it is plausible that several findings about programming languages like C/C++ and Java -- the most common choices for fault localization research -- carry over to other languages, whether the dynamic nature of Python and how the language is used in practice affect the capabilities of classic fault localization approaches remain open questions to investigate. This paper is the first multi-family large-scale empirical study of fault localization on real-world Python programs and faults. Using Zou et al.'s recent large-scale empirical study of fault localization in Java as the basis of our study, we investigated the effectiveness (i.e., localization accuracy), efficiency (i.e., runtime performance), and other features (e.g., different entity granularities) of seven well-known fault-localization techniques in four families (spectrum-based, mutation-based, predicate switching, and stack-trace based) on 135 faults from 13 open-source Python projects from the BugsInPy curated collection. The results replicate for Python several results known about Java, and shed light on whether Python's peculiarities affect the capabilities of fault localization. The replication package that accompanies this paper includes detailed data about our experiments, as well as the tool FauxPy that we implemented to conduct the study.

description: We present an application of evolutionary algorithms to the curve-fitting problems commonly encountered when trying to extract particle masses from correlators in Lattice QCD. Harnessing the flexibility of evolutionary methods in global optimization allows us to dynamically adapt the number of states to be fitted along with their energies so as to minimize overall χ^2/(d.o.f.), leading to a promising new way of extracting the mass spectrum from measured correlation functions.

description: We present the exact solution of the Falicov-Kimball model after a sudden change of its interaction parameter using non-equilibrium dynamical mean-field theory. For different interaction quenches between the homogeneous metallic and insulating phases the system relaxes to a non-thermal steady state on time scales on the order of hbar/bandwidth, showing collapse and revival with an approximate period of h/interaction if the interaction is large. We discuss the reasons for this behavior and provide a statistical description of the final steady state by means of generalized Gibbs ensembles.

The Evolving Faint-End of the Luminosity Function

Publisher: name: arXiv
Year: 2007

subject: FOS: Physical sciences

description: We investigate the evolution of the faint-end slope of the luminosity function, $α$, using semi-analytical modeling of galaxy formation. In agreement with observations, we find that the slope can be fitted well by $α(z) =a+b z$, with a=-1.13 and b=-0.1. The main driver for the evolution in $α$ is the evolution in the underlying dark matter mass function. Sub-L_* galaxies reside in dark matter halos that occupy a different part of the mass function. At high redshifts, this part of the mass function is steeper than at low redshifts and hence $α$ is steeper. Supernova feedback in general causes the same relative flattening with respect to the dark matter mass function. The faint-end slope at low redshifts is dominated by field galaxies and at high redshifts by cluster galaxies. The evolution of $α(z)$ in each of these environments is different, with field galaxies having a slope b=-0.14 and cluster galaxies b=-0.05. The transition from cluster-dominated to field-dominated faint-end slope occurs roughly at a redshift $z_* \sim 2$, and suggests that a single linear fit to the overall evolution of $α(z)$ might not be appropriate. Furthermore, this result indicates that tidal disruption of dwarf galaxies in clusters cannot play a significant role in explaining the evolution of $α(z)$ at z< z_*. In addition we find that different star formation efficiencies a_* in the Schmidt-Kennicutt-law and supernovae-feedback efficiencies $ε$ generally do not strongly influence the evolution of $α(z)$.

Correlation of macroscopic instability and Lyapunov times in the general three-body problem

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: We conducted extensive numerical experiments of equal mass three-body systems until they became disrupted. The system lifetimes, as a bound triple, and the Lyapunov times show a correlation similarto what has been earlier obtained for small bodies in the Solar System. Numerical integrations of several sets of differently randomised initial conditions produced the same relationship of the instability time and Lyapunov time. Marginal probability densities of the various times in the three-body experiments are also discussed. Our high accuracy numerical method for three-body orbit computations and Lyapunov time determinations is concisely described.

Sources of educational philosophy implemented in western Canadian art galleries : an analysis of the educational, curatorial and institutional educative philosophy of seven western Canadian art galleries and its effect on the organizational structure of art institutions in the 1980's
Creators: name: Campbell, Nancy
Publisher: name: University of British Columbia
Year: 2010

description: The problem of this study was to explicate both the curatorial and art educational philosophies that underlie educative programming in seven western Canadian art galleries. The underlying premise of the study, reflecting the literature of the field, was that curatorial and art educational philosophies within the art institution were not congruent. This perceived incongruency was believed to be the cause of art institutions to fall short of their task to interpret art and exhibition to the public successfully. As a result of this premise information regarding the nature of this incongruency needed to be collected. Related information regarding the possibility of a cooperative inter-departmental networking of objectives, educational goals and philosophy between curators and educators, as well as an exploration of the organizational structures of the gallery, also needed to be collected. The study employed survey research procedures. The survey was conducted using a questionnaire which was administered by personal and telephone interview to seven curators and seven art educators in seven western Canadian art galleries. The results of the study show that it is not solely the differing philosophical and ideological beliefs of the educators and curators functioning within the art institution which make the development of strong educational gallery programming difficult. It was found that, in general, curators and educators support the educational mission of galleries today, despite differing personal or departmental goals. The larger problem revealed in the study regarding the establishment of a strong educative programme in the art gallery is a problem of tradition, hierarchy in job position, and the basic organizational structure of the gallery itself. The findings show that it is the organization of galleries which has to adapt in order to support the growing educational mission. Implications of these results are discussed and suggestions for further research are outlined.

description: Anchoring porphyrin, ZnPAc, featuring cyanoacetic acid group has been synthesized for application in a dye-sensitized solar cell. Capping layer dyes zinc meso-tetraphenyl porphyrin (ZnTPP) with anchoring porphyrin ZnPAc through axial coordination bonds of Zn-to-ligand self-assembles solar cell devices. With the introduction of cyanoacetic acid anchor, the higher electrons are effectively injected into the TiO2 semiconductor surface. Thus, the ZnTPP-ZnPAc-based device has more short-circuit current (JSC) compared with our previously reported ZnTPP-ZnPA-based solar cell. The ZnPA and ZnPAc porphyrin anchoring dyes maintain a broad absorption spectrum and also improve electron injection and lower charge recombination compared to our previous reports on organic molecule anchored dye W3. Hence, the ZnTPP-ZnPAc self-assembled dye has higher power conversion efficiency. The assembled modes were also verified by transmission electron microscopy (TEM). To understand ZnTPP-ZnPAc for photovoltaic performance trends, we have carried out charge extraction, transient photovoltage decay and electrochemical impedance spectroscopy analysis.

description: We predict that a photon condensate inside a dye-filled microcavity forms long-lived spatial structures that resemble vortices when incoherently excited by a focused pump orbiting around the cavity axis. The finely structured density of the condensates have a discrete rotational symmetry that is controlled by the orbital frequency of the pump spot and is phase-coherent over its full spatial extent despite the absence of any effective photon-photon interactions.
