description: The goals of functional Magnetic Resonance Imaging (fMRI) include high spatial and temporal resolutions with a high signal-to-noise ratio (SNR). We introduce a novel method for fMRI named Oscillating Steady-State Imaging (OSSI). OSSI can provide 2 to 3 times higher SNR than the standard method. However, the SNR improvement comes at a cost of spatial-temporal resolution. To simultaneously improve spatial and temporal resolutions and maintain the high SNR advantage of OSSI, we present novel pipelines for fast acquisition and high-resolution fMRI reconstruction and physics parameter quantification. We design a sparse sampling pattern to accelerate scan time. Because OSSI images are high-dimensional, we propose a patch-tensor low-rank model to exploit the local spatial-temporal low-rankness of the images. The proposed method enables high-resolution 3D fMRI with a factor 10 acceleration and 1.3 mm spatial resolution, and yields 2 times higher SNR than the standard fMRI methods with 2 times more brain activation. To accurately model the nonlinearity of OSSI oscillation pattern, instead of applying subspace models that might not be perfectly suited for the data, we propose a physics-based manifold model that builds the MR physics for OSSI signal generation as a regularizer for the undersampled reconstruction. The proposed manifold model reconstructs high-resolution fMRI images with high SNR and a factor of 12 acceleration. Furthermore, the model enables dynamic tracking of important physics parameters for more accurate brain activity monitoring with a 150 ms temporal resolution. To exploit learning-based approaches for dynamic MRI with better temporal modeling and richer representations, we propose a voxel-wise attention network that combines MR physics with the attention mechanism for temporal learning and mapping. We also develop a two-stage learning scheme to resolve the training data limitation. The proposed network reconstructs dynamic MRI sequences with a factor of 12 undersampling and provides high-quality functional maps with 4 times faster reconstruction than model-based approaches. With novel models for acquisition and reconstruction, we demonstrate that we can improve SNR and resolution simultaneously without compromising scan time. All the proposed models outperform other comparison approaches with higher resolution and more functional information.

description: Teacher well-being is becoming increasingly important in research and in education policy. However, studies that investigate the well-being of pre-service teachers empirically are still scarce and tend to use instruments that assess general well-being or focus only on negative aspects such as stress and strain. Therefore, this study tests the psychometric properties of the pre-service teacher well-being questionnaire. The questionnaire draws on research in well-being psychology and aims to capture pre-service teacher well-being as a multidimensional and context-specific construct. The underlying model consists of three positive dimensions, (1) positive attitudes towards initial teacher education, (2) enjoyment of initial teacher education, and (3) positive academic self-concept regarding initial teacher education, and three negative dimensions, (4) worries about initial teacher education, (5) physical complaints related to initial teacher education, and (6) social problems in initial teacher education. Evidence presented in this study is based on an online survey that pre-service teachers for primary and secondary school from Switzerland (n = 989; primary education: 76.8 %), Germany (n = 563; primary education: 16.3 %), and Austria (n = 197; primary education: 76.6 %) completed in spring 2022. Results confirmed the factor structure and the reliability of the instrument for all but one factor, and there is evidence for correspondence with other well-being constructs. Furthermore, partial measurement invariance was established between the three countries' subsamples. These findings support the use of the instrument for assessing pre-service teacher well-being. Directions for future research and implications for initial teacher education institutions are discussed.
Asymmetric ac fluxon depinning in a Josephson junction array: A highly discrete limit

description: Directed motion and depinning of topological solitons in a strongly discrete damped and biharmonically ac-driven array of Josephson junctions is studied. The mechanism of the depinning transition is investigated in detail. We show that the depinning process takes place through chaotization of an initially standing fluxon periodic orbit. Detailed investigation of the Floquet multipliers of these orbits shows that depending on the depinning parameters (either the driving amplitude or the phase shift between harmonics) the chaotization process can take place either along the period-doubling scenario or due to the type-I intermittency.

description: About 2500 square degrees of sky south of declination -25 degrees and/or near the galactic plane were surveyed for bright outer solar system objects. This survey is one of the first large scale southern sky and galactic plane surveys to detect dwarf planets and other bright Kuiper Belt objects in the trans-Neptunian region. The survey was able to obtain a limiting R-band magnitude of 21.6. In all, 18 outer solar system objects were detected, including Pluto which was detected near the galactic center using optimal image subtraction techniques to remove the high stellar density background. Fourteen of the detections were previously unknown trans-Neptunian objects, demonstrating that the southern sky had not been well-searched to date for bright outer solar system objects. Assuming moderate albedos, several of the new discoveries from this survey could be in hydrostatic equilibrium and thus be considered dwarf planets. Combining this survey with previous surveys from the northern hemisphere suggests that the Kuiper Belt is nearly complete to around 21st magnitude in the R-band. All the main dynamical classes in the Kuiper Belt are occupied by at least one dwarf planet sized object. The 3:2 Neptune resonance, which is the innermost well-populated Neptune resonance, has several large objects while the main outer Neptune resonances such as the 5:3, 7:4, 2:1, and 5:2 do not appear have any large objects. This indicates that the outer resonances are either significantly depleted in objects relative to the 3:2 resonance or have a significantly different assortment of objects than the 3:2 resonance. For the largest objects (H<4.5 mag), the scattered disk population appears to have a few times more objects than the main Kuiper Belt population, while the Sedna population could be several times more than that of the main Kuiper Belt.

description: Learning analytics researchers have been diligently integrating trace data to study Self-Regulated Learning (SRL). Compared to traditionally used survey data, trace data, such as log or clickstream data designed and interpreted to understand a certain SRL construct, are considered to be more effective in capturing dynamic SRL as fine-grained events. Yet, trace data is not completely free from validity issues, since researchers’ understanding of contexts and target constructs heavily affect the validity of design and interpretation of trace data. Rather, researchers can adopt survey and trace data to complement each other. They can also compare survey and trace data on the same construct to deepen the understanding of what each type of data captures. The aim of this dissertation is to understand the different nature of self-reported survey and trace data and to adopt context-specific indicators for particular SRL constructs. This dissertation is composed of three studies, each of which employed both survey and trace data to answer specific SRL-related questions. In Chapter 3, the first study demonstrates the importance of reflection in facilitating learning from hints through integrating complementary surveys and log data. The second study in Chapter 4 contrasts the alignment between achievement goal theory and trace data, and the misalignment between the theory and survey responses. The third study presented in Chapter 5 investigates causes of misalignments and builds theoretical interpretation from data. This dissertation contributes to the field of learning analytics and SRL in multiple ways. First of all, the dissertation shows that effort in posing more valid methodological approaches could contribute to theories. In Chapters 4 and 5, I revealed the huge difference between learners’ goal statement before learning and goal-relevant behaviors during learning, and questioned some of the previous findings that heavily relied upon survey data. Furthermore, it emphasizes the importance of thoroughly understanding targeted constructs in specific contexts. Only then, can we select a strongly valid methodological approach.

description: We study the noise spectra of a many-level quantum dot coupled to two electron reservoirs, when interactions are taken into account only on the dot within the Hartree-Fock approximation. The dependence of the noise spectra on the interaction strength, the coupling to the leads, and the chemical potential is derived. For zero bias and zero temperature, we find that as a function of the (external) frequency, the noise exhibits steps and dips at frequencies reflecting the internal structure of the energy levels on the dot. Modifications due to a finite bias and finite temperatures are investigated for a non-interacting two-level dot. Possible relations to experiments are pointed out.

description: A cyber-physical system (CPS) with both autonomous and manual control capabilities, or a semi-autonomous (SA) system, is one of the most commonly seen types of system in our daily lives, such as cars, airplanes and ships. While having the benefits of autonomous control to enhance safety/comfort of transportation and the flexibility of manual control to handle safety-critical situations, SA systems inevitably inherit the vulnerabilities embedded in both control types. That is, an SA system will also suffer from component failures or design/software bugs (e.g., crashes of Boeing 737 MAX) and potential attacks (e.g., sensor spoofing) as a general CPS does. Moreover, since mechanical components are gradually being replaced by their electronic counterparts in SA systems, this trend also introduces new reliability and security risks — increasing adoption of multiple heterogeneous communication interfaces widens attack surfaces that an adversary can exploit. Considering the potential security and safety concerns caused by system faults/flaws, human error, and malicious attacks, we develop a suite of mechanisms/systems for detection and resolution of system anomalies by cross-validating the sensor data and the context information to enhance the security and safety of SA systems from three key perspectives that can directly influence the operation of SA systems — system operation, received information, and control decisions. In this thesis, we propose both domain-general design for SA systems and its domain-specific realization using SA vehicles as a concrete case study. From the system operation perspective, we propose CADD, a context-aware anomaly detection system, to capture abnormal system behavior under various operation contexts while considering practical scenarios where some (context) information cannot be observed by the SA system. We then present DiVa, a diagnostic system that pinpoints/identifies the anomalous source(s) after an anomaly is detected. It exploits the cyber-physical correlation or causality between the internal data of the SA system to narrow down the origin of anomaly while assuming no data can be entirely trusted. From the received information perspective, we propose EDRoad, an easy-to-use system for verification of the data received from external sources to ensure no compromised data will be used to provide services to the SA systems. Finally, from the control decision perspective, we introduce CADCA, a system for detecting and resolving control actions that may potentially lead to unstable system states or safety-critical situations.

description: The following tables represent effort, retained catch (kept), and discard as reported on longline log sheets for the Hawaii Limited-access longline fishery. To satisfy confidentiality RFMO reporting standards, data from the California-based longline fishery is also included in this report. Catch-and-effort statistics are summarized from logbook data submitted to the PIFSC, FRMD and are based on date of longline haul. The statistics originate from an Oracle table LLDS_REPORT_STATS_HICA database extraction done on 3 May 2016. When a statistic (number of vessels, trips) can involve dates of haul in 2 summary periods (i.e. years, semiannual, quarters) the item is counted in both summary periods. Thus, a trip total is for "partial and completed" trips. As such, these are not additive statistics (i.e. sum of 4 quarters is not the total for the year, etc.).
Extracting the strain-softening response of composites using full-field displacement measurement
Creators: name: Zobeiry, Navid
Publisher: name: University of British Columbia
Year: 2010

description: From both numerical and experimental standpoints, it is very desirable to develop a general methodology that can be used to determine the strain-softening response and characteristic damage properties (e.g. fracture energy, damage height) of quasi-brittle materials. In the absence of a direct methodology, one has to conduct multiple experiments combined with trial-and-error procedures and/or simplifying assumptions regarding the damaging behaviour of the material in order to construct a strain-softening curve. In this study, a new methodology is developed that directly identifies the damaging constitutive response of composite materials using full-field measurements of kinematic variables. Using this methodology, the damage related properties can be extracted and the strain-softening response of composite materials under mode I loading can be obtained directly. Compared to other available indirect approaches, this method invokes fewer assumptions about the behaviour of the material and does not require any prior assumption regarding the shape of the constitutive response, as is required in other approaches. A series of compact compression and over-height compact tension tests are conducted on IM7/8552 quasi-isotropic laminates. Using the digital image correlation technique, full-field displacement vectors of the specimen surface are measured in each test. Based on the acquired data and using the basic principles of mechanics (equilibrium and compatibility), a family of approximate stress-strain curves are obtained. These approximate curves are then used in an iterative process to determine the optimized strain-softening response of the laminate. To validate the capability of the method to capture the local damaging behaviour of the composite laminate, a series of destructive tests such as deplying and sectioning are performed on the damaged specimens. The tested laminates are also simulated using finite element analyses of the specimens that employ the extracted strain-softening curve as input to a damage mechanics based material model. The proposed methodology provides insight into the details of damage propagation in composite materials and is a promising tool for characterizing the strain-softening behaviour of composite laminates in a relatively easy and direct manner.

description: This dissertation analyzes discrimination and wage inequality in different contexts - interactions over an online peer-to-peer platform and discretionary disclosure of salary history under a new policy that is intended to alleviate wage inequality. We study these using online field and online lab experiments as well as collecting data through web scraping. The first chapter studies communication among applicants and prospective employers where salary history disclosure is discretionary. Several states and cities have recently adopted Salary History Bans (SHB) that take away to right to ask about applicants’ salary histories from prospective employers. The goal of SHB is to alleviate race and gender wage gap. However, given the productivity signaling value of past salary, it is natural to expect voluntary disclosure by applicants. How will SHB impact employers’ inference under wage gap? We use signals that are a biased representation of uniformly distributed types to represent “past salary” in our virtual lab setting. We mimic wage inequality through two different sender groups with disproportionate endowment of either lower or higher signals, referred to as “Disadvantaged” and “Advantaged” groups respectively. We use a theoretical model to reflect employer naivete in interpreting past salary information or the lack thereof. Both theory and experimental data suggest that employers under(over)estimate types when dis- closed signals are low (high) for the Disadvantaged (Advantaged) group. Further, employers overestimate types when signals are not disclosed. Our experiment reveals that the un- der(over)estimation of disclosed signals is of greater magnitude under voluntary disclosure. In addition, the receiver naivete induced mistakes are of greater magnitude for disclosed signals than nondisclosed signals. Our results suggest that SHB can instead worsen the existing wage discrepancies. The second chapter is an audit study investigating discrimination against Arab/Muslim identity over Airbnb, a classic example of online marketplace that allows users to post or rent short-term housing in residential premises. We demonstrate an important consequence of Airbnb’s current market design. We run an online audit study over Airbnb and display nine percentage point gap between the acceptance rate of requests from guests with distinctively Arab/Muslim identities and those of distinctively non-Arab/Muslim identities. The difference persists across different specifications.
STUDY OF MACROTURBULENCE AND BURSTING VIA THE -1 SPECTRAL POWER LAW REGION OF TURBULENT OPEN CHANNEL FLOWS OVER GRAVEL BEDS

Subjects: subject: Hydraulic Engineering

description: The large scale and smaller production scale motions contain over the half of turbulent kinetic energy in the flow. These motions are responsible for sediment transport and deposition processes, contaminant mixing and stream bio-diversity. These motions are corresponded to the left and right bounds of -1 power region of the spectral energy. The most well recognized and highly studied power law has been upon Kolmogorov’s -5/3 power law region of the streamwise spectral energy density and this research focused on investigating the -1 power region bounds and energy. Energy budget and time-average turbulence calculations along with spectral analysis are performed to investigate the characteristics of large scale and smaller production scale motions in the flow. Spectral analyses of turbulent flows offers the utility of investigating the distribution of turbulent energy across wavenumber scales as well as identifying prominent wavenumbers at which the periodicity of coherent processes are centered. In turn, the results of spectral analyses can be coupled with visualization of coherent vortices and time-average turbulence results to advance our understanding of turbulent energy distribution and dominant processes that drive environmental phenomena such as sediment transport and solute transfer. A new method for identifying the wavenumbers associated to the macroturbulence and bursting is introduced. Also this study offers a new scaling method of energy spectral that derived from the turbulence energy model for an equilibrium boundary layer. Results of this study show an equilibrium boundary layer for the outer region of the flow in which the flow is uniform and fully-developed. Also for a given roughness, the results of this study provide an approach to calculate the streamwise turbulence kinetic energy of bursting and macroturbulence which show a linkage of this work to applications such as bedload and suspended load sediment transport.

description: Apprenticeship is a system of learning a craft or trade from one who is engaged in it and of paying for instruction for a given number of years of work. The practice was known in ancient Babylon, Egypt, Greece and Rome, as well as modern Europe and to some extent the United States of America. It was typical in the medieval Europe for a master craftsman to agree to instruct a young man, to give him shelter, food and clothing to work for the master for a given time. The apprentice after this becomes a journey person who will work for the master for wages, or he/she sets up as master him/herself.

description: The radial profiles of the Hb, Mg, and Fe line-strength indices are presented for a sample of eight spiral galaxies with a low surface-brightness stellar disc and a bulge. The correlations between the central values of the line-strength indices and velocity dispersion are consistent to those known for early-type galaxies and bulges of high surface-brightness galaxies. The age, metallicity, and alpha/Fe enhancement of the stellar populations in the bulge-dominated region are obtained using stellar population models with variable element abundance ratios. Almost all the sample bulges are characterized by a young stellar population, on-going star formation, and a solar alpha/Fe enhancement. Their metallicity spans from high to sub-solar values. No significant gradient in age and alpha/Fe enhancement is measured, whereas only in a few cases a negative metallicity gradient is found. These properties suggest that a pure dissipative collapse is not able to explain formation of all the sample bulges and that other phenomena, like mergers or acquisition events, need to be invoked. Such a picture is also supported by the lack of a correlation between the central value and gradient of the metallicity in bulges with very low metallicity. The stellar populations of the bulges hosted by low surface-brightness discs share many properties with those of high surface-brightness galaxies. Therefore, they are likely to have common formation scenarios and evolution histories. A strong interplay between bulges and discs is ruled out by the fact that in spite of being hosted by discs with extremely different properties, the bulges of low and high surface-brightness discs are remarkably similar.

description: Background: The importance of play for children and its potential for learning are widely recognized. However, it is contested whether teachers should guide play, particularly pretend play, and how guided pretend play supports children’s agency and learning. In this study, pretend play is employed in (unplugged) digital education and the teacher’s guidance and children’s involvement are examined to answer the following questions: what roles do teachers take on during guided pretend play and how do they enable children’s learning about digitalization and digital transformation? Aims: This qualitative study examines how teachers guide pretend play in ways that support learning, focusing on the topic of digitalization and digital transformation. Sample: Fifteen teachers took part in the study and implemented the pretend play suggestions in their kindergartens with children aged from four to six years. Method: The pretend play was filmed. The video data were structured and sequences of teachers joining in the pretend play and guiding from within were selected. These sequences were analysed in-depth using multimodal interaction analysis. Results: The results indicate that teachers guide pretend play from within by taking on different roles (play leader or co-player). Teachers model within pretend play, for example, by assigning tasks or thinking aloud, and provide scaffolding, encouraging children’s learning about digitalization and digital transformation. Conclusion: Through co-playing and leading, teachers support a prolonged and in-depth joint focus, as well as the agency of the children. Such guided play is termed “sustained shared playing” and has great potential for learning.

			genome reference (EMBL/ENA under the project number PRJEB13501 with accession numbers FKKI010000001-FKKI011581707). The alignment was constructed using BWA (version 0.7.0). Subsequently the
			discovery of VPs was performed using SAMtools (version 0.1.18) and BCFtools (version 0.1.11). A posterior filtering was performed subsequently using minimal read depth (5), a minimal quality score
			(100) and a homozygous filter removing heterozygous positions. The discovered diversity spectrum is diverging between genotypes with low diversity (1,153,300 VPs detected in Lo90) to genotypes with
			high diversity (2,161,068 VPs detected in Lo351). In addition to the diversity in the elite breeding pools, we also detected 3,871,617 VPs in the S. vavivolii line. All VPs subsequently were
			processed by the tool CooVar to construct a functional annotation using 27,784 predicted rye gene models.

description: Recently, a new type of symmetry for three-qubit quantum states was introduced, the so-called Greenberger-Horne-Zeilinger (GHZ) symmetry. It includes the operations which leave the three-qubit standard GHZ state unchanged. This symmetry is powerful as it yields families of mixed states that are, on the one hand, complex enough from the physics point of view and, on the other hand, simple enough mathematically so that their properties can be characterized analytically. We show that by using the properties of GHZ-symmetric states it is straightforward to derive optimal witnesses for three-qubit entanglement.

description: Bulges can be classified into classical and pseudobulges; the former are considered to be end products of galactic mergers and the latter to form via secular evolution of galactic disks. Observationally, bulges of disk galaxies are mostly pseudobulges, including the Milky Way's. We here show, by using self-consistent cosmological simulations of galaxy formation, that the formation of pseudobulges of Milky Way-sized disk galaxies has mostly completed before disk formation; thus the main channel of pseudobulge formation is not secular evolution of disks. Our pseudobulges form by rapid gas supply at high-redshift and their progenitors would be observed as high-redshift disks.

description: The following tables represent effort, retained catch (kept) and discard as reported on longline log sheets for the Hawaii limited-access longline fishery. To satisfy confidentiality RFMO reporting standards, data from the California-based longline fishery is also included in this report. Catch-and-effort statistics are summarized from logbook data submitted to the PIFSC, FRMD and are based on date of longline haul. The statistics originate from an Oracle table LLDS_REPORT_STATS_HICA database extraction done on 3 May 2016. When a statistic (number of vessels, trips) can involve dates of haul in 2 summary periods (i.e. years, semiannual, quarters) the item is counted in both summary periods. Thus, a trip total is for “partial and completed” trips. As such, these are not additive statistics (i.e. sum of 4 quarters is not the total for the year, etc).

description: NGC7538 is a complex massive star-forming region. The region is composed of several radio continuum sources, one of which is IRS1, a high-mass protostar, from which a 0.3 pc molecular bipolar outflow was detected. Several maser species have been detected around IRS1. The CH3OH masers have been suggested to trace a Keplerian-disk, while the H2O masers are almost aligned to the outflow. More recent results suggested that the region hosts a torus and potentially a disk, but with a different inclination than the Keplerian-disk that is supposed to be traced by the CH3OH masers. Tracing the magnetic field close to protostars is fundamental for determining the orientation of the disk/torus. Recent studies showed that during the protostellar phase of high-mass star formation the magnetic field is oriented along the outflows and around or on the surfaces of the disk/torus. The observations of polarized maser emissions at milliarcsecond resolution can make a crucial contribution to understanding the orientation of the magnetic field and, consequently, the orientation of the disk/torus in NGC7538-IRS1. The NRAO Very Long Baseline Array was used to measure the linear polarization and the Zeeman-splitting of the 22GHz H2O masers toward NGC7538-IRS1. The European VLBI Network and the MERLIN telescopes were used to measure the linear polarization and the Zeeman-splitting of the 6.7GHz CH3OH masers toward the same region. We detected 17 H2O masers and 49 CH3OH masers at high angular resolution. We detected linear polarization emission toward two H2O masers and toward twenty CH3OH masers. The CH3OH masers, most of which only show a core structure, seem to trace rotating and potentially infalling gas in the inner part of a torus. Significant Zeeman-splitting was measured in three CH3OH masers. [...] We also propose a new description of the structure of the NGC7538-IRS1 maser region.

Bond behaviour of fibre reinforced polymer (FRP) rebars in concrete
Creators: name: Quayyum, Shahriar
Publisher: name: University of British Columbia

description: Recently, fibre reinforced polymer (FRP) rebars have been extensively used in construction instead of steel rebars due to their non-corrosive nature and high tensile strength. Bond between FRP rebars and concrete is a critical design parameter that controls the performance of reinforced concrete members at serviceability and ultimate limit states. In order to prevent a bond failure, an adequate anchorage length should be provided. The anchorage length is derived using a bond stress-slip ( ) constitutive law. The objective of this study is to investigate the effect of different parameters such as the type of fibre, the rebar surface and the confinement provided by the transverse reinforcement on the bond behaviour of FRP rebars in concrete. Based on the analysis, a generalized bond stress-slip relationship will be developed and a new design equation for the required anchorage length of FRP rebar in concrete will be derived. A database was created on the bond stress-slip behaviour of FRP rebars in concrete from the available literature up to 2009. The data was statistically analyzed to investigate the effect of the different parameters on the bond performance of FRP rebars. It was observed that an increase in the confinement provided by the transverse reinforcement increased the bond strength of FRP rebars in concrete. This signifies that the presence of transverse reinforcement affects the bond behaviour of FRP rebars in concrete and hence, it should be taken into consideration while developing design equations for FRP rebars. Type of fibre and rebar surface does not affect the bond stress, but the latter affects the slip corresponding to the peak bond stress. Based on the results, a nonlinear regression analysis was performed to develop the bond stress-slip model for splitting mode of failure and a design equation for determining the development length of the FRP rebars in concrete was derived. The proposed development length equation can save about 10%-15% of the development length than that required by different code equations. This can save a considerable amount of FRP materials, which will eventually reduce the overall cost of construction and thereby, encourage the use of FRP reinforcing bars in the construction of concrete structures.

description: Imperfect capital markets and commitment problems impede lumpy human capital investments. Labeled loans have been postulated as a potential solution to both constraints, but little is known about the role of the label in influencing investment choices in practice. We draw on a cluster randomized controlled trial in rural India to test predictions from a theoretical model, providing novel evidence that labeled microcredit is effective in influencing household borrowing and investment decisions and increasing take-up of a lumpy human capital investment, a toilet.

description: We demonstrate that the high-quality cooling data observed for the young neutron star in the supernova remnant Cassiopeia A over the past 10 years--as well as all other reliably known temperature data of neutron stars--can be comfortably explained within the "nuclear medium cooling" scenario. The cooling rates of this scenario account for medium-modified one-pion exchange in dense matter and polarization effects in the pair-breaking formations of superfluid neutrons and protons. Crucial for the successful description of the observed data is a substantial reduction of the thermal conductivity, resulting from a suppression of both the electron and nucleon contributions to it by medium effects. We also find that possibly in as little as about ten years of continued observation, the data may tell whether or not fast cooling processes are active in this neutron star.
