description: We propose noise oscillation measurements in a double point contact, accessible with current technology, to seek for a signature of the non-abelian nature of the ν=5/2 quantum Hall state. Calculating the voltage and temperature dependence of the current and noise oscillations, we predict the non-abelian nature to materialize through a multiplicity of the possible outcomes: two qualitatively different frequency dependences of the nonzero interference noise. Comparison between our predictions for the Moore-Read state with experiments on ν=5/2 will serve as a much needed test for the nature of the ν=5/2 quantum Hall state.

description: Among several authors, who studied massive and massless scalar meson fields in general relativity, attempts to obtain a complete set of solutions for a conformally flat metric $e^ψ\left({dx^1}^2 + {dx^2}^2 + {dx^3}^2 - {dx^4}^2\right)$ were made by Ray for massive and massless mesons and Gursay for massless mesons. Both of them concluded that $ψ$ must be a function of $K_0\left({dx^1}^2 + {dx^2}^2 + {dx^3}^2 -{dx^4}^2\right) + K_1 x^1 + K_2 x^2 + K_3 x^3 + K_4 x^4$, where, where $K_0,~K_1,~ K_2,~K_3,~K_4$ are all constants. Both Ray and Gursay, however, overlooked an important particular case, which is studied here. As a by-product certain equations obtained by Auria and Regge in connection with "Gravitational theories with asymptotic flat Instantons," are solved under less restrictive assumptions.

description: We introduce a class of 1D models mimicking a single-lane bridge with two junctions and two particle species driven in opposite directions. The model exhibits spontaneous symmetry breaking (SSB) for a range of injection/extraction rates. In this phase the steady state currents of the two species are not equal. Moreover there is a co-existence region in which the symmetry broken phase co-exists with a symmetric phase. Along a path in which the extraction rate is varied, keeping the injection rate fixed and large, hysteresis takes place. The mean field phase diagram is calculated and supporting Monte-Carlo simulations are presented. One of the transition lines exhibits a kink, a feature which cannot exist in transition lines of equilibrium phase transitions.

description: For stationary light fields, manifestation of statistical properties such as coherence and polarization are attributed to the same physical phenomena, i.e. correlations in fluctuations of optical fields. In order to explain various properties associated with electromagnetic optical fields, both coherence and polarization need to be placed at same footings. This leads to two-point (space or time) generalization of single-point properties such as Stokes parameters and elements of coherency matrix. This paper reviews the basic aspects concerning vectorial optical fields and experimental methods developed during last couple of decades for the measurement of two-point correlation functions of electromagnetic optical fields in spatial and temporal domain. Studies related to coherence properties of optical fields have led to several important technological applications during last seven decades, which are also discussed briefly in this review.

subject: FOS: Civil engineering

description: Connecting design thinking to making throughout the design process creates an awareness of materials, the assembly process, and of one's self.  The discoveries made through an iterative, cyclical process can be invaluable to a variety of professions, especially when involving collaboration.  The University of Maryland College Park (UMCP) has multiple disciplines related to the built environment and art and design.  Several of these buildings are located on the perceived "back side" of campus with little interaction among the programs.  How can architecture foster making in an educational environment and promote collaboration and a sense of place among a variety of interests and disciplines?  With the recent maker movement cultivating around the world and the fact that many disciplines associated with art and design have always supported thinking through making, UMCP could benefit from a facility that promotes learning-by-doing as well as collaboration among a variety of disciplines.

Innovative Bayesian and Frequentist Adaptive Designs in Late-Phase Oncology Clinical Trials
Creators: name: Kravets, Sasha
Publisher: name: University of Illinois at Chicago
Year: 2024

description: In this dissertation, we present two methodological works in the areas of Bayesian and frequentist adaptive statistical designs in late-phase oncology clinical trials. Late-phase oncology clinical trials may incorporate various adaptive features and the focus of this dissertation is on Bayesian trial monitoring and sample size re-estimation methods. In the first part of the dissertation, we focus on therapeutic late-phase oncology clinical trials with time-to-event endpoints. Overall survival (OS) serves as the most reliable and preferred clinical endpoint, while endpoints such as progression-free survival (PFS) are used to make early futility or efficacy decisions. Progression-free survival and overall survival are strongly connected endpoints but may not always reflect strong associations in numerical measures, and their relationship is rarely taken into consideration in the design of a clinical trial. We propose a clinical trial design based on an early endpoint of PFS and a final endpoint of OS via the semi-competing risks framework, with trial monitoring conducted utilizing stochastic ordering of posterior predictive probabilities. In the second part of this dissertation, we shift our focus to parallel-arm pragmatic late-phase oncology clinical trials, specifically in cancer care delivery. Parallel-arm cluster-randomized trials (CRT) are increasingly utilized to understand cancer care in real-world settings. Cluster-randomized trials possess a hierarchical data structure in which subjects are clustered within units such as clinics or providers. In CRTs, sample size and power calculations rely on the intraclass correlation coefficient (ICC), which quantifies the degree of between-cluster variability. Underestimation of the ICC may lead to significantly reduced study power to detect the treatment effect. We propose extensions of several popular adaptive sample size re-estimation methods, including the internal pilot study approach and the promising zone-design based on conditional power.

description: The transient accreting millisecond pulsar SAX J1808.4-3658 has shown several outbursts to date but the transition from outburst to quiescence has never been investigated in detail. Thanks to the Swift observing flexibility, we monitored for the first time the decay to quiescence during the 2005 outburst. At variance with other transients, wide luminosity variations are observed. In addition, close to quiescence, SAX J1808.4-3658 seems to switch between two different states. We interpret them in terms of the accretion states accessible to a magnetized, fast rotating neutron star.

Extending the processing capabilities of a pilot scale retort
Creators: name: Britt, Ian John
Publisher: name: University of British Columbia
Year: 2010

description: The object of this research was to develop a retort for research and development of thermal processes which use common commercial thermal processing techniques. An FMC 500W laboratory sterilizer, designed to operate with an FMC weir product racking system, was modified for conventional steam, positive flow steam/air and water immersion/air overpressure thermal processing of foods in thin profile retortable packages. The research included the modification of the retort plumbing and the fabrication of a set of product trays and a racking system. The completed system was tested for temperature distribution and stability, and heat transfer distribution for each processing mode. The latter was achieved by comparing the heat penetration parameters calculated from the centerpoint temperature histories of conduction heating teflon transducers.

description: The benzene...ethene and parallel-displaced (PD) benzene...benzene dimers are the most fundamental systems involving p-p stacking interactions. Several high-level ab initio investigations calculated the binding energies of these dimers at the CCSD(T)/CBS level of theory using various approaches such as reduced virtual orbital spaces and/or MP2-based basis set corrections. Here we obtain CCSDT(Q) binding energies using a Weizmann-3-type approach. In particular, we extrapolate the SCF, CCSD, and (T) components using large heavy-atom augmented Gaussian basis sets (namely, SCF/jul-cc-pV{5,6}Z, CCSD/jul-cc-pV{Q,5}Z, and (T)/jul-cc-pV{T,Q}Z). We consider post-CCSD(T) contributions up to CCSDT(Q), inner-shell, scalar-relativistic, and Born-Oppenheimer corrections. Overall, our best relativistic, all-electron CCSDT(Q) binding energies are Delta Ee,all,rel = 1.234 (benzene...ethene) and 2.550 (benzene...benzene PD), Delta H0 = 0.949 (benzene...ethene) and 2.310 (benzene...benzene PD), and Delta H298 = 0.130 (benzene...ethene) and 1.461 (benzene...benzene PD) kcal/mol. Important conclusions are reached regarding the basis set convergence of the SCF, CCSD, (T), and post-CCSD(T) components. Explicitly correlated calculations are used as a sanity check on the conventional binding energies. Overall, post-CCSD(T) contributions are destabilizing by 0.028 (benzene...ethene) and 0.058(benzene...benzene) kcal/mol, thus they cannot be neglected if 0.1 kcal/mol accuracy is sought.

description: We present a comprehensive analysis of quantum fluctuation effects in the superfluid ground state of an attractively interacting Fermi system, employing the attractive Hubbard model as a prototype. The superfluid order parameter, and fluctuations thereof, are implemented by a bosonic Hubbard-Stratonovich field, which splits into two components corresponding to longitudinal and transverse (Goldstone) fluctuations. Physical properties of the system are computed from a set of approximate flow equations obtained by truncating the exact functional renormalization group flow of the coupled fermion-boson action. The equations capture the influence of fluctuations on non-universal quantities such as the fermionic gap, as well as the universal infrared asymptotics present in every fermionic superfluid. We solve the flow equations numerically in two dimensions and compute the asymptotic behavior analytically in two and three dimensions. The fermionic gap Δis reduced significantly compared to the mean-field gap, and the bosonic order parameter α, which is equivalent to Δin mean-field theory, is suppressed to values below Δby fluctuations. The fermion-boson vertex is only slightly renormalized. In the infrared regime, transverse order parameter fluctuations associated with the Goldstone mode lead to a strong renormalization of longitudinal fluctuations: the longitudinal mass and the bosonic self-interaction vanish linearly as a function of the scale in two dimensions, and logarithmically in three dimensions, in agreement with the exact behavior of an interacting Bose gas.

The targum (1949:Jan. 4 - 1949:Jan. 14)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1949

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: We present high angular resolution imaging of the quasar PSO J172.3556+18.7734 at $z=6.82$ with the Very Long Baseline Array (VLBA). This source currently holds the record of being the highest redshift radio-loud quasar. These observations reveal a dominant radio source with a flux density of $398.4 \pm 61.4~μ$Jy at 1.53 GHz, a deconvolved size of $9.9 \times 3.5$ mas ($52.5 \times 18.6$ pc), and an intrinsic brightness temperature of ($4.7 \pm 0.7) \times 10^7$ K. A weak unresolved radio extension from the main source is also detected at $\sim~3.1σ$ level. The total flux density recovered with the VLBA at 1.53 GHz is consistent with that measured with the Very Large Array (VLA) at a similar frequency. The quasar is not detected at 4.67 GHz with the VLBA, suggesting a steep spectral index with a limit of $α^{1.53}_{4.67} < -$1.55. The quasar is also not detected with the VLBA at 7.67 GHz. The overall characteristics of the quasar suggest that it is a very young radio source similar to lower redshift Gigahertz Peaked Spectrum radio sources, with an estimated kinematic age of $\sim~10^3$ years. The VLA observations of this quasar revealed a second radio source in the field $23\rlap{.}{''}1$ away. This radio source, which does not have an optical or IR counterpart, is not detected with the VLBA at any of the observed frequencies. Its non-detection at the lowest observed VLBA frequency suggests that it is resolved out, implying a size larger than ~$0\rlap{.}{''}17$. It is thus likely situated at lower redshift than the quasar.

Labor union objectives under a multi-contract period time horizon
Creators: name: Kiess-Moser, Paul Michael
Publisher: name: University of British Columbia
Year: 2010

description: Most microeconomic models of Labor unions take the union's membership size as exogenous, and limit union members' time horizons to a single contract period. Particularly for unions allocating employment by means of a seniority system, and for unions facing stochastic demand for labor conditions, these limitations in current union models lead to unsatisfactory predictions of union behavior. In this thesis, an n-period majority voting model of a monopoly union facing a fixed demand for labor schedule and allocating employment by seniority is developed to show the interdependence between the union's present wage choice, the size of the union's future voter pool and its future wage choices. Union members are assumed to predict the union's future voting behavior, and to account for the consequences of the retirement of senior union members. The optimal contract wage is shown analytically to be not lower than that wage which causes the layoff of twice the number of retiring workers per contract period in each contract period, and not to exceed the wage level at which half of the union's present voter pool would lose its union employment. Computer simulation solutions for various demand conditions suggest that after a potential sharp first-period increase in the contract wage, the union's contract wage path follows its analytically derived lower limit - with each contract, union employment declines by twice the number of retirees per contract period. The time path of union employment is shown to be largely independent of anticipated changes in demand for labor. A similar two-period model is developed for stochastic demand for labor conditions. For some cases, the union's wage choice can be shown to be lower when the consequences of this period's wage choice on next period's voter pool are taken into account. Majority voting instability problems cannot be ruled out for this type of model, and are interpreted as a potential cause for a union-internal political process. These seniority-based models are then compared with models where union employment is allocated by a random draw among union members. With nonstochastic demand for labor, this allows for the analysis of discrete changes in union rules, and yields the principal prediction that the union will eventually replace an employment by random draw rule with employment according to seniority. The economic approach to the analysis of union behavior is assessed critically, and put in some perspective by an informal discussion of other union-internal determinants of union behavior. In conclusion, it is suggested that the formal prediction of an ongoing gradual decline in union employment may be usefully amended by considering potential benefits from union size maintenance and union membership rejuvenation.

description: In specific conditions and crisis situations such as the pandemic of coronavirus (SARS-CoV-2), or the COVID-19 disease, e-learning systems be-came crucial for the smooth performing of teaching and other educational pro-cesses. In such scenarios, the availability of e-learning ecosystem elements is further highlighted. An indicator of the importance for securing the availability of such an ecosystem is evident from the DDoS (Distributed Denial of Service) attack on AAI@EduHr as a key authentication service for number of e-learning users in Republic of Croatia. In doing so, numerous users (teach-ers/students/administrators) were prevented from implementing and participat-ing in the planned teaching process. Given that DDoS as an anomaly of network traffic has been identified as one of the key threats to the e-learning ecosystem in crisis scenarios, this research will focus on overview of methodology for de-veloping a model for proactive detection of DDoS traffic. The challenge in de-tection is to effectively differentiate the increased traffic intensity and service requests caused by legitimate user activity (flash crowd) from the illegitimate traffic caused by a DDoS attack. The DDoS traffic detection model developed by following analyzed methodology would serve as a basis for providing further guidelines and recommendations in the form of response to events that may negatively affect the availability of e-learning ecosystem elements such as DDoS attack.

description: In this paper we discuss an infinite class of AdS$_6$ backgrounds in Type IIB supergravity dual to five dimensional SCFTs whose low energy description is in terms of linear quiver theories. The quantisation of the Page charges imposes that each solution is determined once a convex, piece-wise linear function is specified. In the dual field theory, we interpret this function as encoding the ranks of colour and flavour groups in the associated quiver. We check our proposal with several examples and provide general expressions for the holographic central charge and the Wilson loop VEV. Some solutions outside this general class, with less clear quiver interpretation, are also discussed.

Magnetoelectric bistabilities in ferromagnetic resonant tunneling structures

Publisher: name: arXiv
Year: 2008
Subjects: subject: Other Condensed Matter (cond-mat.other)
subject: FOS: Physical sciences

description: The conditions for the occurrence of pronounced magnetoelectric bistabilities in the resonant tunneling through a ferromagnetic quantum well are theoretically investigated. The bistability appears due to the mutual feedback of the carriers Coulomb interaction and the carriers exchange coupling with magnetic impurities in the well. It is shown that the well Curie temperature depends strongly on the relative alignment of the quantum well level and the reservoirs chemical potentials, which can be modified electrically. Switching between a "current-on/magnetism-off" and a "current-off/magnetism-on" mode becomes possible, if the well temperature lies in-between the bistable values of the well Curie temperature.

description: In a recent paper we proposed that the giant planets' primordial orbits may have been eccentric (~0.05), and used a suite of dynamical simulations to show outcomes of the giant planet instability that are consistent with their present-day orbits. In this follow-up investigation, we present more comprehensive simulations incorporating superior particle resolution, longer integration times, and eliminating our prior means of artificially forcing instabilities to occur at specified times by shifting a planets' position in its orbit. While we find that the residual phase of planetary migration only minimally alters the the planets' ultimate eccentricities, our work uncovers several intriguing outcomes in realizations where Jupiter and Saturn are born with extremely large eccentricities (~0.10 and ~0.25, respectively). In successful simulations, the planets' orbits damp through interactions with the planetesimal disk prior to the instability, thus loosely replicating the initial conditions considered in our previous work. Our results therefore suggest an even wider range of plausible evolutionary pathways are capable of replicating Jupiter and Saturn's modern orbital architecture.

description: The temperature scales of screening of local magnetic and orbital moments are important characteristics of strongly correlated substances. In a recent paper X. Deng et al. using dynamic mean-field theory (DMFT) have identified temperature scales of the onset of screening in orbital and spin channels in some correlated metals from the deviation of temperature dependence of local susceptibility from the Curie law. We argue that the scales obtained this way are in fact much larger, than the corresponding Kondo temperatures, and, therefore, do not characterize the screening process. By reanalyzing the results of this paper we find the characteristic (Kondo) temperatures for screening in the spin channel $T_K\approx 100$ K for V$_2$O$_3$ and $T_K\approx 350$ K for Sr$_2$RuO$_4$, which are almost an order of magnitude smaller than those for the onset of the screening estimated in the paper ($1000$ K and $2300$ K, respectively); for V$_2$O$_3$ the obtained temperature scale $T_K$ is therefore comparable to the temperature of completion of the screening, $T^{\rm comp}\sim 25$ K, which shows that the screening in this material can be described in terms of a single temperature scale.

description: Optical observations of the Oort cloud comet C/2017 K2 (PANSTARRS) show that its activity began at large heliocentric distances (up to 35 au), which cannot be explained by either the sublimation or the crystallization of water ice. Supervolatile sublimation, most likely of carbon monoxide (CO), has been proposed as a plausible driver of the observed mass loss. Here, we present the detection of the J = 2$-$1 rotational transition in outgassed CO from C/2017 K2 when at heliocentric distance $r_H$ = 6.72 au, using the James Clerk Maxwell Telescope. The CO line is blue-shifted by 0.20$\pm$0.03 km s$^{-1}$ with an area and width of 8.3$\pm$2.3 mK km s$^{-1}$ and $0.28\pm$0.08 km s$^{-1}$, respectively. The CO production rate is $Q_{CO} = (1.6\pm0.5) \times10^{27}$ s$^{-1}$. These are the first observations of a gaseous species in C/2017 K2 and provide observational confirmation of the role of supervolatile sublimation in this comet.

description: Bald patches are magnetic topologies in which the magnetic field is concave up over part of a photospheric polarity inversion line. A bald patch topology is believed to be the essential ingredient for filament channels and is often found in extrapolations of the observed photospheric field. Using an analytic source-surface model to calculate the magnetic topology of a small bipolar region embedded in a global magnetic dipole field, we demonstrate that although common in closed-field regions close to the solar equator, bald patches are unlikely to occur in the open-field topology of a coronal hole. Our results give rise to the following question: What happens to a bald patch topology when the surrounding field lines open up? This would be the case when a bald patch moves into a coronal hole, or when a coronal hole forms in an area that encompasses a bald patch. Our magnetostatic models show that, in this case, the bald patch topology almost invariably transforms into a null point topology with a spine and a fan. We argue that the time-dependent evolution of this scenario will be very dynamic since the change from a bald patch to null point topology cannot occur via a simple ideal evolution in the corona. We discuss the implications of these findings for recent Hinode XRT observations of coronal hole jets and give an outline of planned time-dependent 3D MHD simulations to fully assess this scenario.

description: We construct explicit $δ$-bracketing covers with minimal cardinality for the set system of (anchored) rectangles in the two dimensional unit cube. More precisely, the cardinality of these $δ$-bracketing covers are bounded from above by $δ^{-2} + o(δ^{-2})$. A lower bound for the cardinality of arbitrary $δ$-bracketing covers for $d$-dimensional anchored boxes from [M. Gnewuch, Bracketing numbers for axis-parallel boxes and applications to geometric discrepancy, J. Complexity 24 (2008) 154-172] implies the lower bound $δ^{-2}+O(δ^{-1})$ in dimension $d=2$, showing that our constructed covers are (essentially) optimal. We study also other $δ$-bracketing covers for the set system of rectangles, deduce the coefficient of the most significant term $δ^{-2}$ in the asymptotic expansion of their cardinality, and compute their cardinality for explicit values of $δ$.

THE EFFECTS OF GENDER ON PHYSICAL CHILD ABUSE AND NEGLECT SENTENCING IN MARYLAND CIRCUIT COURTS

description: Researchers have identified child abuse as a major social problem in the United States, yet research on physical child abuse and neglect sentencing is limited. Prior to this study, sentencing research has mostly overlooked physical child abuse and neglect as a distinct crime. As physical child abuse and neglect are so contrary to traditional notions of femininity, studying the effects of gender on sentencing for these narrowly defined crimes presents an opportunity to focus on females as countertypes. The findings here imply that the effects of being female (a countertype) increases for the most serious crime, first degree child abuse, in both the decision to incarcerate and on the sentence length.
Brownian ratchets driven by asymmetric nucleation of hydrolysis waves

description: We propose a stochastic process wherein molecular transport is mediated by asymmetric nucleation of domains on a one-dimensional substrate. Track-driven mechanisms of molecular transport arise in biophysical applications such as Holliday junction positioning and collagenase processivity. In contrast to molecular motors that hydrolyze nucleotide triphosphates and undergo a local molecular conformational change, we show that asymmetric nucleation of hydrolysis waves on a track can also result in directed motion of an attached particle. Asymmetrically cooperative kinetics between ``hydrolyzed'' and ``unhydrolyzed'' states on each lattice site generate moving domain walls that push a particle sitting on the track. We use a novel fluctuating-frame, finite-segment mean field theory to accurately compute steady-state velocities of the driven particle and to discover parameter regimes which yield maximal domain wall flux, leading to optimal particle drift.

The Gamma-ray Albedo of the Moon

description: We use the GEANT4 Monte Carlo framework to calculate the gamma-ray albedo of the Moon due to interactions of cosmic ray (CR) nuclei with moon rock. Our calculation of the albedo spectrum agrees with the EGRET data. We show that the spectrum of gamma rays from the Moon is very steep with an effective cutoff around 3-4 GeV (600 MeV for the inner part of the Moon disk) and exhibits a narrow pion-decay line at 67.5 MeV, perhaps unique in astrophysics. Apart from other astrophysical sources, the albedo spectrum of the Moon is well understood, including its absolute normalisation; this makes it a useful "standard candle" for gamma-ray telescopes. The steep albedo spectrum also provides a unique opportunity for energy calibration of gamma-ray telescopes, such as the forthcoming Gamma Ray Large Area Space Telescope (GLAST). Since the albedo flux depends on the incident CR spectrum which changes over the solar cycle, it is possible to monitor the CR spectrum using the albedo gamma-ray flux. Simultaneous measurements of CR proton and helium spectra by the Payload for Antimatter-Matter Exploration and Light-nuclei Astrophysics (PAMELA), and observations of the albedo gamma rays by the GLAST Large Area Telescope (LAT), can be used to test the model predictions and will enable the LAT to monitor the CR spectrum near the Earth beyond the lifetime of the PAMELA.

Supersymmetric Wilson loops at two loops

description: We study the quantum properties of certain BPS Wilson loops in ${\cal N}=4$ supersymmetric Yang-Mills theory. They belong to a general family, introduced recently, in which the addition of particular scalar couplings endows generic loops on $S^3$ with a fraction of supersymmetry. When restricted to $S^2$, their quantum average has been further conjectured to be exactly computed by the matrix model governing the zero-instanton sector of YM$_2$ on the sphere. We perform a complete two-loop analysis on a class of cusped Wilson loops lying on a two-dimensional sphere, finding perfect agreement with the conjecture. The perturbative computation reproduces the matrix-model expectation through a highly non-trivial interplay between ladder diagrams and self-energies/vertex contributions, suggesting the existence of a localization procedure.

Moving from Cross-Project Defect Prediction to Heterogeneous Defect Prediction: A Partial Replication Study

description: Software defect prediction heavily relies on the metrics collected from software projects. Earlier studies often used machine learning techniques to build, validate, and improve bug prediction models using either a set of metrics collected within a project or across different projects. However, techniques applied and conclusions derived by those models are restricted by how identical those metrics are. Knowledge coming from those models will not be extensible to a target project if no sufficient overlapping metrics have been collected in the source projects. To explore the feasibility of transferring knowledge across projects without common labeled metrics, we systematically integrated Heterogeneous Defect Prediction (HDP) by replicating and validating the obtained results. Our main goal is to extend prior research and explore the feasibility of HDP and finally to compare its performance with that of its predecessor, Cross-Project Defect Prediction. We construct an HDP model on different publicly available datasets. Moreover, we propose a new ensemble voting approach in the HDP context to utilize the predictive power of multiple available datasets. The result of our experiment is comparable to that of the original study. However, we also explored the feasibility of HDP in real cases. Our results shed light on the infeasibility of many cases for the HDP algorithm due to its sensitivity to the parameter selection. In general, our analysis gives a deep insight into why and how to perform transfer learning from one domain to another, and in particular, provides a set of guidelines to help researchers and practitioners to disseminate knowledge to the defect prediction domain.
Wisdom for the Crowd: Discoursive Power in Annotation Instructions for Computer Vision

description: Developers of computer vision algorithms outsource some of the labor involved in annotating training data through business process outsourcing companies and crowdsourcing platforms. Many data annotators are situated in the Global South and are considered independent contractors. This paper focuses on the experiences of Argentinian and Venezuelan annotation workers. Through qualitative methods, we explore the discourses encoded in the task instructions that these workers follow to annotate computer vision datasets. Our preliminary findings indicate that annotation instructions reflect worldviews imposed on workers and, through their labor, on datasets. Moreover, we observe that for-profit goals drive task instructions and that managers and algorithms make sure annotations are done according to requesters' commands. This configuration presents a form of commodified labor that perpetuates power asymmetries while reinforcing social inequalities and is compelled to reproduce them into datasets and, subsequently, in computer vision systems.

description: Interstellar masers are unique probes of the environments in which they arise. In studies of high-mass star formation their primary function has been as signposts of these regions and they have been used as probes of the kinematics and physical conditions in only a few sources. With a few notable exceptions, we know relatively little about the evolutionary phase the different maser species trace, nor their location with respect to other star formation tracers. While detailed studies of a small number of maser regions can reveal much about them, other information can only be obtained through large, systematic searches. In particular, such surveys are vital in efforts to determine an evolutionary sequence for the common maser species, and there is growing evidence that methanol masers may trace an earlier phase than the other common maser species of OH and water.
