description: It is generally assumed that the central galaxy in a dark matter halo, that is, the galaxy with the lowest specific potential energy, is also the brightest halo galaxy (BHG), and that it resides at rest at the centre of the dark matter potential well. This central galaxy paradigm (CGP) is an essential assumption made in various fields of astronomical research. In this paper we test the validity of the CGP using a large galaxy group catalogue constructed from the Sloan Digital Sky Survey. For each group we compute two statistics, ${\cal R}$ and ${\cal S}$, which quantify the offsets of the line-of-sight velocities and projected positions of brightest group galaxies relative to the other group members. By comparing the cumulative distributions of $|{\cal R}|$ and $|{\cal S}|$ to those obtained from detailed mock group catalogues, we rule out the null-hypothesis that the CGP is correct. Rather, the data indicate that in a non-zero fraction $f_{\rm BNC}(M)$ of all haloes of mass $M$ the BHG is not the central galaxy, but instead, a satellite galaxy. In particular, we find that $f_{\rm BNC}$ increases from $\sim 0.25$ in low mass haloes ($10^{12} h^{-1} {\rm M_{\odot}} \leq M \lsim 2 \times 10^{13} h^{-1}{\rm M_{\odot}}$) to $\sim 0.4$ in massive haloes ($M \gsim 5 \times 10^{13} h^{-1} {\rm M_{\odot}}$). We show that these values of $f_{\rm BNC}$ are uncomfortably high compared to predictions from halo occupation statistics and from semi-analytical models of galaxy formation. We end by discussing various implications of a non-zero $f_{\rm BNC}(M)$, with an emphasis on the halo masses inferred from satellite kinematics.

description: Most image super-resolution (SR) methods are developed on synthetic low-resolution (LR) and high-resolution (HR) image pairs that are constructed by a predetermined operation, e.g., bicubic downsampling. As existing methods typically learn an inverse mapping of the specific function, they produce blurry results when applied to real-world images whose exact formulation is different and unknown. Therefore, several methods attempt to synthesize much more diverse LR samples or learn a realistic downsampling model. However, due to restrictive assumptions on the downsampling process, they are still biased and less generalizable. This study proposes a novel method to simulate an unknown downsampling process without imposing restrictive prior knowledge. We propose a generalizable low-frequency loss (LFL) in the adversarial training framework to imitate the distribution of target LR images without using any paired examples. Furthermore, we design an adaptive data loss (ADL) for the downsampler, which can be adaptively learned and updated from the data during the training loops. Extensive experiments validate that our downsampling model can facilitate existing SR methods to perform more accurate reconstructions on various synthetic and real-world examples than the conventional approaches.

description: The first part of this deliverable is a scoping review of the literature examining 147 articles published in peer review academic journals over the past ten years (2013-2023) on the promotion of research ethics and integrity (REI), and breaches of these standards including research misconduct (RM) and questionable research practices (QRPs). It also identifies current challenges, gaps in knowledge and practice, and opportunities for both further research, and policy and educational interventions to promote REI and mitigate RM and QRPs. Findings on state-of-the-art knowledge in REI research suggest some areas of consensus, including on the greater risks for early career researchers to commit RM and the value of responsible conduct of research (RCR) training, particularly approaches that emphasize ethical problem-solving skills. However, the study also identified a lack of consensus in other areas, including the rehabilitation and reintegration of researchers who committed RM. Key findings extracted from the review contribute to the understanding that the environment in which researchers operate and other contextual factors significantly influence RCR, rather than primarily the individual behavior of researchers. As such, these environmental and contextual factors require further research and policy attention. The second part reports the findings of a review of real-life cases on REI, RM and QRPs. This review provides an in-depth qualitative evaluation of 23 cases that have appeared in the news media in the last five years across four partner countries within the BEYOND consortium – Estonia (3 cases), Latvia (5 cases), the Netherlands (9 cases) and the UK (6 cases). It thematically analyses these cases in relation to reporting and whistle-blowing, gender aspects (including discrimination, sexual harassment, and other forms of gender-based violence) and researcher working conditions, and identifies several novel and emerging factors affecting REI. Significant findings from this review include: the increasingly complex gender dimensions of REI in contemporary research; the changing nature of senior researchers’ responsibility for RM; the roles of social media and online platforms in uncovering and publicizing RM; and the growing politicization of REI concerns in relation to wider political controversies. The review uses these findings to suggest evidence-based practical interventions to better monitor and prevent RM and QRPs, and offers recommendations for further research based on gaps identified in its analysis

description: After the considerable excitement caused by COVID-19 and the first telework measures, many management issues became apparent and some questions quickly arose, especially about efficiency of employees' work and conditions for successful telework adoption. This study focuses on the following questions: what is the new interest to telework for employees and what are the potential reasons for this? How much employees feel able to do their work remotely now and why? To answer these questions, we conducted a survey over several weeks, that involved employees coming from different industries (N=170), in order to collect their experience, skills and motivations for teleworking. The results show that adoption of telework is real for the respondents. Those who have experienced it present a strong motivation and a real capacity to use it, with almost no technological barriers. The theoretical model that we used, based on Technology Acceptance Models (TAM), has highlighted an important new factor of telework adoption: time saved in commuting. The study points out that adoption of telework could be sustainable for both public and private organizations, and this requires a critical examination and discussion.

The design and implementation of a run-time analysis and interactive debugging environment
Creators: name: Johnson, Mark Scott
Publisher: name: University of British Columbia
Year: 2010

description: The design and implementation of a language-independent, interactive system to facilitate the analysis and symbolic debugging of computer programs written in high-level languages is presented. The principal features of the system, called RAIDE, are: (1) Host source language independence is supported by the abstraction of language entities and constructs (for example, variables, constants, procedures, statements, and events) with a language interfacer providing language-dependent details; (2) Translators can cooperate with RAIDE at varying levels of detail; (3) The user interacts with RAIDE and an executing object program using an extendable debugging language, called Dispel; (4) Primitive debugging actions are kept to a minimum and nonprimitive actions (for example, tracing, snapshots, and postmortem dumping) are provided by user-supplied and library procedures written in Dispel; and (5) The implementation is aided by simulation of a virtual debugging machine, called SPAM. To demonstrate RAIDE's feasibility, a prototype implementation was undertaken, including a SPAM simulator and the modification of two language translators (namely, Asple and BCPL) to interface with RAIDE. Besides describing the external and internal designs of the debugging system, the abstract machine, and the debugging language, the thesis also discusses the advantages and shortcomings of each of these components. Numerous examples of debugging commands written in Dispel are given. Two significant side-effects of the research are reported; reflections on the software tools supporting the implementation, and suggestions for translator design to facilitate run-time debugging. The thesis contains a substantial annotated bibliography and an extensive index.
Chemical Bonding of Termination Species in 2D Carbides Investigated through Valence Band UPS/XPS of Ti3C2Tx MXene

description: MXenes are technologically interesting 2D materials that show potential in numerous applications. The properties of the MXenes depend at large extent on the selection of elements that build the 2D MX-layer. Another key parameter for tuning the attractive material properties is the species that terminate the surfaces of the MX-layers. Although being an important parameter, experimental studies on the bonding between the MX-layers and the termination species are few and thus an interesting subject of investigation. Here we show that the termination species fluorine (F) bonds to the Ti3C2-surface mainly through Ti 3p - F 2p hybridization and that oxygen (O) bonds through Ti 3p - O 2p hybridization with a significant contribution of Ti 3d and Ti 4p. The study further shows that the Ti3C2-surface is not only terminated by F and O on the threefold hollow face-centered-cubic (fcc) site. A significant amount of O sits on a bridge site bonded to two Ti surface atoms on the Ti3C2-surface. In addition, the results provide no support for hydroxide (OH) termination on the Ti3C2-surface. On the contrary, the comparison of the valence band intensity distribution obtained through ultraviolet- and x-ray photoelectron spectroscopy with computed spectra by density of states, weighed by matrix elements and sensitivity factors, reveals that OH cannot be considered as an inherent termination species in Ti3C2Tx. The results from this study have implications for correct modeling of the structure of MXenes and the corresponding materials properties. Especially in applications where surface composition and charge are important, such as supercapacitors, Li-ion batteries, electrocatalysis, and fuel- and solar cells, where intercalation processes are essential.

description: We apply the decoherence formalism to an interacting scalar field theory. In the spirit of the decoherence literature, we consider a "system field" and an "environment field" that interact via a cubic coupling. We solve for the propagator of the system field, where we include the self-energy corrections due to the interaction with the environment field. In this paper, we consider an environment in the vacuum state (T=0). We show that neglecting inaccessible non-Gaussian correlators increases the entropy of the system as perceived by the observer. Moreover, we consider the effect of a changing mass of the system field in the adiabatic regime, and we find that at late times no additional entropy has been generated.

description: The Noether-like operators that play an essential role in writing down the invariants for systems of two ordinary differential equations (ODEs) are constructed. The classification of such operators is carried out with the help of analytic continuation of the Lagrangians on the line. Cases in which the Noether-like operators are also Noether symmetries for the systems of ODEs are briefly mentioned. In particular, the 8-dimensional maximal Noether subalgebra is remarkabely obtained for the simplest system of the free particle equations in two dimensions from the 5-dimensional complex Noether algebra. We present the effectivness of Noether-like operators as well as the determination of all first integrals of systems of nonlinear differential equation which have not been reported before. This study gives a new direction to construct first integrals for systems of nonlinear differential equations.

description: The validity of optimized dynamical decoupling (DD) is extended to analytically time dependent Hamiltonians. As long as an expansion in time is possible the time dependence of the initial Hamiltonian does not affect the efficiency of optimized dynamical decoupling (UDD, Uhrig DD). This extension provides the analytic basis for (i) applying UDD to effective Hamiltonians in time dependent reference frames, for instance in the interaction picture of fast modes and for (ii) its application in hierarchical DD schemes with $π$ pulses about two perpendicular axes in spin space. to suppress general decoherence, i.e., longitudinal relaxation and dephasing.

Accounting for Changes in the Distribution of Data

Subjects: subject: Statistics
subject: FOS: Mathematics

description: Accomodating changes to the distribution of data in classification and inference procedures is an importantproblem for statistics. For instance, statistical predictions often rely on the assumption that future data will follow the same distribution as past data, and predictions may fail when there is a change to the data generating process. In other cases, detecting changes to the distribution of data is of scientific interest itself. For example, when monitoring a patient's brain activity, a change may have serious health implications; and in cellular biology, characterizing differences between biological conditions is a key goal for experiments.
Force microscopy cantilevers locally heated in a fluid: temperature fields and effects on the dynamics

description: Atomic force microscopy cantilevers are often, intentionally or not, heated at their extremity. We describe a model to compute the resulting temperature field in the cantilever and in the surrounding fluid on a wide temperature range. In air and for common geometries, the heat fluxes in the cantilever and to the environment are of comparable magnitude. We then infer how the fluid-structure interaction is modified due to heating, and predict the induced changes in the dynamics of the system. In particular, we describe how the resonance frequencies of the cantilever shift with a temperature increase due to two competing processes: softening of the cantilever, and decrease of the fluid inertial effects. Our models are illustrated by experiments on a set of cantilevers spanning the relevant geometries to explore the relative importance of both effects.

The corresponding first order phase transition is preceded by a rapidly increasing mobility and diffusion of Na ions above 200K. Above 291 K the 23Na NMR response is similar to that previously observed in superionic conductors with planar Na layers.

description: A key aspect of machine learning models lies in their ability to learn efficient intermediate features. However, the input representation plays a crucial role in this process, and polyphonic musical scores remain a particularly complex type of information. In this paper, we introduce a novel representation of symbolic music data, which transforms a polyphonic score into a continuous signal. We evaluate the ability to learn meaningful features from this representation from a musical point of view. Hence, we introduce an evaluation method relying on principled generation of synthetic data. Finally, to test our proposed representation we conduct an extensive benchmark against recent polyphonic symbolic representations. We show that our signal-like representation leads to better reconstruction and disentangled features. This improvement is reflected in the metric properties and in the generation ability of the space learned from our signal-like representation according to music theory properties.

description: We consider the transverse field Ising model in $(2+1)$D, putting 12 spins at the vertices of the regular icosahedron. The model is tiny by the exact diagonalization standards, and breaks rotation invariance. Yet we show that it allows a meaningful comparison to the 3D Ising CFT on $\mathbb{R}\times S^2$, by including effective perturbations of the CFT Hamiltonian with a handful of local operators. This extreme example shows the power of conformal perturbation theory in understanding finite $N$ effects in models on regularized $S^2$. Its ideal arena of application should be the recently proposed models of fuzzy sphere regularization.

title: An Evaluation of Distributive Education at Tooele High School
Creators: name: Jensen, Hubert J.
Publisher: name: Utah State University
Year: 1969

description: An ever-increasing number of youth, upon leaving school, are finding employment in the distributive organizations--stores of all kinds, wholesale establishments, brokerage concerns, and other businesses. Studies and investigations show that more extensive and more effective training for employment is one of the outstanding needs of youth and adult workers in these occupations. It was to supply these needs in part, at least that, in succession of vocational a c ts, Congress provided for the training of persons employed in distributive occupations.
J. W. Edgerton, Public Relations Director for thew. T. Grant Company , in commenting on the Nation's strength and distributive education , stated:
Considering the fact that 53 percent of the total job opportunity exists in the distributive occupations, it becomes obvious that distributive education has a mighty job to do . • . a mighty responsibility ••• a mighty opportunity.
To meet the increasing need for trained personnel in the distributive occupations, Tooele High School started a cooperative distributive education program in the 1964-1965 school year. Enrollment steadily increased. Twenty-five students were enrolled during the 1968-1969 school year.
With the increasing emphasis that has been placed on vocational education by the Vocational Education Ac t of 1963, and the 1968 Amendments, the business education department at Tooele High School was faced with the challenge of providing suitable training stations within the business community. There was also a need to advise the parents and students in the area supported by Tooele High School of the need for training in a distributive occupation.

description: The Hubble relation between distance and redshift is a purely cosmographic relation that depends only on the symmetries of a FLRW spacetime, but does not intrinsically make any dynamical assumptions. This suggests that it should be possible to estimate the parameters defining the Hubble relation without making any dynamical assumptions. To test this idea, we perform a number of inter-related cosmographic fits to the legacy05 and gold06 supernova datasets. Based on this supernova data, the "preponderance of evidence" certainly suggests an accelerating universe. However we would argue that (unless one uses additional dynamical and observational information) this conclusion is not currently supported "beyond reasonable doubt". As part of the analysis we develop two particularly transparent graphical representations of the redshift-distance relation -- representations in which acceleration versus deceleration reduces to the question of whether the relevant graph slopes up or down. Turning to the details of the cosmographic fits, three issues in particular concern us: First, the fitted value for the deceleration parameter changes significantly depending on whether one performs a chi^2 fit to the luminosity distance, proper motion distance or other suitable distance surrogate. Second, the fitted value for the deceleration parameter changes significantly depending on whether one uses the traditional redshift variable z, or what we shall argue is on theoretical grounds an improved parameterization y=z/(1+z). Third, the published estimates for systematic uncertainties are sufficiently large that they certainly impact on, and to a large extent undermine, the usual purely statistical tests of significance. We conclude that the supernova data should be treated with some caution.

Leaks and the legitimation of state power: How the 2013 NSA disclosures reshaped debates over U.S. government surveillance
Creators: name: Pollak, Calvin
Publisher: name: Carnegie Mellon University
Year: 2021
Subjects: Rhetoric

description: Scholars in discourse studies have defined legitimation as the justification (and critique) of powerful institutions and their practices. In moments of crisis, legitimation tactics often shift. This dissertation considers how such shifts areincited by unauthorized leaks. Leaks, I argue, constitute freshly available texts that reveal privileged institutional information presented in a specialized rhetorical style. Some leaks bear culturally, semantically, and formally valuable features that help them to circulate widely, stymying institutional efforts to thwart their circulation. But few scholars have examined how the recontextualization of leaked texts affects legitimation arguments’ content and style. To explore how leaked documents are harnessed in the public arguments of institutional critics and defenders, my dissertation examines the 2013 leaks of classified National Security Agency (NSA) documents. Combining corpus analysis with discourse analysis, I explore how the NSA leaks affected the online writing of the anti-NSA American Civil Liberties Union and the pro-NSA Brookings Institution. I also consider overlaps between the rhetorical patterns in the leaked NSA documents, the news reports about them, and the ACLU’s and Brookings Institution's post-leaks writing. In addition, I directly compare how these two organizations’ ideologies – civil-libertarianism and national-securitarianism – affected their styles of argument in response to the leaks. Findings from my three analyses suggest that both ACLU and Brookings writers moved from a more informal, character-based style pre-leaks to a moreinformationally-dense, technical style post-leaks, and that they shifted their arguments from those primarily grounded in the law to those primarily grounded in power dynamics and authorization by other institutions. I also find that in the postleaks period, the two organizations’ ideologies break down over a set of core questions, often building diametrically opposed arguments on very similar, yetsemantically distinct, sets of evidence. This dissertation contextualizes and clarifies these findings with recourse to the leaked textual material that inaugurated thecontroversy. Thus, I use key leaked NSA documents drawn upon in the post-leaks texts to explain the stylistic and argumentative changes that my analyses have uncovered. Overall, my study suggests that future leaks of this quantity (many texts) and quality (culturally, semantically, and formally valuable) are likely to influence the legitimation styles of subsequent policy arguments.

description: The stem-loop (SL1) is the 5'-terminal structural element within the single-stranded SARS-CoV-2 RNA genome. It is formed by nucleotides 7–33 and consists of two short helical segments interrupted by an asymmetric internal loop. This architecture is conserved among Betacoronaviruses. SL1 is present in genomic SARS-CoV-2 RNA as well as in all subgenomic mRNA species produced by the virus during replication, thus representing a ubiquitous cis-regulatory RNA with potential functions at all stages of the viral life cycle. We present here the ¹H, ¹³C and ¹⁵N chemical shift assignment of the 29 nucleotides-RNA construct 5_SL1, which denotes the native 27mer SL1 stabilized by an additional terminal G-C base-pair.

description: Background: Crucial foundations of any quantitative systems biology experiment are correct genome and proteome annotations. Protein databases compiled from high quality empirical protein identifications that are in turn based on correct gene models increase the correctness, sensitivity, and quantitative accuracy of systems biology genome-scale experiments. Results: In this manuscript, we present the Drosophila melanogaster PeptideAtlas, a fly proteomics and genomics resource of unsurpassed depth. Based on peptide mass spectrometry data collected in our laboratory the portal http://www.drosophila-peptideatlas.org allows querying fly protein data observed with respect to gene model confirmation and splice site verification as well as for the identification of proteotypic peptides suited for targeted proteomics studies. Additionally, the database provides consensus mass spectra for observed peptides along with qualitative and quantitative information about the number of observations of a particular peptide and the sample(s) in which it was observed. Conclusion: PeptideAtlas is an open access database for the Drosophila community that has several features and applications that support (1) reduction of the complexity inherently associated with performing targeted proteomic studies, (2) designing and accelerating shotgun proteomics experiments, (3) confirming or questioning gene models, and (4) adjusting gene models such that they are in line with observed Drosophila peptides. While the database consists of proteomic data it is not required that the user is a proteomics expert. © 2009 Loevenich et al; licensee BioMed Central Ltd.

description: In this work, we present a computational formulation based on continuum mechanics to study the interaction of fluid membranes embedded with semiflexible filaments. This is motivated by systems in membrane biology, such as cytoskeletal networks and protein filaments aiding the cell fission process. We model the membrane as a fluid shell via the Helfrich-Canham energy and the filament as a one-dimensional Cosserat continuum. We assume the filament to be tethered to the surface of the membrane in a way that it is allowed to float on the surface freely. The novel filament-membrane coupling, which is anticipated to yield interesting physics, also gives rise to unique computational challenges, which we address in this work. We present validation results and apply the formulation to certain problems inspired by cellular biology.

description: Given a locally finite simple graph so that its degree is not bounded, every self-adjoint realization of the adjacency matrix is unbounded from above. In this note we give an optimal condition to ensure it is also unbounded from below. We also consider the case of weighted graphs. We discuss the question of self-adjoint extensions and prove an optimal criterium.

description: It has long been proposed that much of the information encoding how a protein folds is contained locally in the peptide chain. Here we present a large-scale simulation study designed to examine the extent to which conformations of peptide fragments in water predict native conformations in proteins. We perform replica exchange molecular dynamics (REMD) simulations of 872 8-mer, 12-mer, and 16-mer peptide fragments from 13 proteins using the AMBER 96 force field and the OBC implicit solvent model. To analyze the simulations, we compute various contact-based metrics, such as contact probability, and then apply Bayesian classifier methods to infer which metastable contacts are likely to be native vs. non-native. We find that a simple measure, the observed contact probability, is largely more predictive of a peptide's native structure in the protein than combinations of metrics or multi-body components. Our best classification model is a logistic regression model that can achieve up to 63% correct classifications for 8-mers, 71% for 12-mers, and 76% for 16-mers. We validate these results on fragments of a protein outside our training set. We conclude that local structure provides information to solve some but not all of the conformational search problem. These results help improve our understanding of folding mechanisms, and have implications for improving physics-based conformational sampling and structure prediction using all-atom molecular simulations.
Semigroups of distributions with linear Jacobi parameters

description: We show that a convolution semigroup of measures has Jacobi parameters polynomial in the convolution parameter $t$ if and only if the measures come from the Meixner class. Moreover, we prove the parallel result, in a more explicit way, for the free convolution and the free Meixner class. We then construct the class of measures satisfying the same property for the two-state free convolution. This class of two-state free convolution semigroups has not been considered explicitly before. We show that it also has Meixner-type properties. Specifically, it contains the analogs of the normal, Poisson, and binomial distributions, has a Laha-Lukacs-type characterization, and is related to the $q=0$ case of quadratic harnesses.

description: We present the first demonstration of vortices in an electron-type cuprate superconductor, the highest $T_c$ (= 43 K) electron-type cuprate $Sr_{0.9}La_{0.1}CuO_2$. Our spatially resolved quasiparticle tunneling spectra reveal a hidden low-energy pseudogap inside the vortex core and unconventional spectral evolution with temperature and magnetic field. These results cannot be easily explained by the scenario of pure superconductivity in the ground state of high-$T_c$ superconductivity.

description: The paper considers the issues of using two-thread electromechanical gantry drive axles as part of the chassis of mass-produced tractors. The Kirovets tractor family was chosen because the issue of replacing the driving wheels with tracked modules is being considered for it, which leads to an increase in the height of the center of gravity of the chassis. The principle of integration of a traction electric motor into the driving axle is proposed. The main computational dependencies illustrating the kinematic and force relations for such structures are considered. The prospects of using technologies tested in the field of tank construction to ensure the release of the drive bridge of the proposed structure are discussed.
Melting Temperature of Metals Based on the Nearly Free Electron Model

description: We propose a general formula for the melting temperature of metals in terms of electronic mass, electronic number, and nearest-neighbor lattice distance. We derive it from the instability of the transverse phonon in the solid phase, using the nearly free electron model. Including higher order terms of vibrations enhanced near the melting temperature, the electronic restoring force is reduced and the ionic one is negligible. This fact greatly brings down the melting temperature, bringing it close to experimental data in the range of 10 % for Cs, Cu, Au, and Ba. Also, this theory confirms the Lindemann criterion.
