description: Acute kidney injury (AKI) is a common complication after lung transplantation (LTx) which is closely related to the poor prognosis of patients. We aimed to explore potential risk factors and outcomes associated with early post-operative AKI after LTx. A retrospective study was conducted in 136 patients who underwent LTx at our institution from 2017 to 2019. AKI was defined according to the Kidney Disease: Improving Global Outcomes (KDIGO) guideline. Univariate and multivariate analyses were conducted to identify risk factors related to AKI. The primary outcome was the incidence of AKI after LTx. Secondary outcomes were associations between AKI and short-term clinical outcomes and mortality. Of the 136 patients analyzed, 110 developed AKI (80.9%). AKI was associated with higher baseline eGFR (odds ratio (OR) 1.01 (95% confidence interval (CI): 1.00–1.03)) and median tacrolimus (TAC) concentration (OR 1.15 (95% CI: 1.02–1.30)). Patients with AKI suffered longer mechanical ventilation days (p = .015) and ICU stay days (p = .011). AKI stage 2–3 patients had higher risk of 1-year mortality (HR 16.98 (95% CI: 2.25–128.45)) compared with no-AKI and stage 1 patients. Our results suggested early post-operative AKI may be associated with higher baseline eGFR and TAC concentrations. AKI stage 1 may have no influence on survival rate, whereas AKI stage 2–3 may be associated with increased mortality at 1-year.

description: We present a formulation of domain wall fermions in the Schroedinger functional by following the universality argument given by Lüscher. To check whether the formulation works, we examine the lowest eigenmode of the free domain wall fermion operator. We confirm that the theory belongs to a correct universality class and that the eigenvector is localized near the boundaries of the fifth dimension. We also investigate the chiral symmetry breaking structure of the four dimentional effective operator. We observe that the bulk chiral symmetry breaking disappears for a large fifth dimensional size, while the breaking originated by the boundary effects persists and exponetially decays away from the time boundaries.

description: The evidence presented earlier by several authors for the substantial disk eccentricity in dwarf novae during their superoutbursts is shown to result either from errors or from arbitrary, incorrect assumptions. In particular, the evidence resulting from hot spot eclipses was based on the assumption that the spot distances are identical with disk radii which is not always correct.

description: Nuclear star clusters (NSCs) are the densest stellar systems in the Universe. They can be found at the center of all galaxy types, but tend to favor galaxies of intermediate stellar mass around 10$^9\,$M$_{\odot}$[1, 2]. Currently, two main processes are under debate to explain their formation: in-situ star-formation from gas infall[3] and migration and merging of globular clusters (GCs) caused by dynamical friction[4]. Studies[5-9] of NSC stellar populations suggest that the former predominates in massive galaxies, the latter prevails in dwarf galaxies, and both contribute equally at intermediate mass. However, up to now, no ongoing merger of GCs has yet been observed to confirm this scenario. Here we report the serendipitous discovery of five dwarf galaxies with complex nuclear regions, characterized by multiple nuclei and tidal tails, using high resolution images from the Hubble Space Telescope. These structures have been reproduced in complementary N-body simulations, supporting the interpretation that they result from migrating and merging of star clusters. The small detection rate and short simulated timescales (below 100 Myr) of this process may explain why this has not been observed previously. This study highlights the need of large surveys with high resolution to fully map the migration scenario steps.

How did supermassive black holes grow? How does large scale structure form? What is the connection between these processes? To address these questions IXO will employ optics with 3 sq m collecting area and 5 arc sec angular resolution - 20 times more collecting area at 1 keV than any previous X-ray observatory. Focal plane instruments will deliver a 100-fold increase in effective area for high-resolution spectroscopy, deep spectral imaging over a wide field of view, unprecedented polarimetric sensitivity, microsecond spectroscopic timing, and high count rate capability. The mission is being planned for launch in 2021 to an L2 orbit, with a five-year lifetime and consumables for 10 years.

description: Formation of giant waves in sea states with two spectral maxima, centered at close wave vectors ${\bf k}_0\pmΔ{\bf k}/2$ in the Fourier plane, is numerically simulated using the fully nonlinear model for long-crested water waves [V. P. Ruban, Phys. Rev. E {\bf 71}, 055303(R) (2005)]. Depending on an angle $θ$ between the vectors ${\bf k}_0$ and $Δ{\bf k}$, which determines a typical orientation of interference stripes in the physical plane, rogue waves arise having different spatial structure. If $θ\lesssim\arctan(1/\sqrt {2})$, then typical giant waves are relatively long fragments of essentially two-dimensional (2D) ridges, separated by wide valleys and consisting of alternating oblique crests and troughs. At nearly perpendicular ${\bf k}_0$ and $Δ{\bf k}$, the interference minima develop to coherent structures similar to the dark solitons of the nonlinear Shroedinger equation, and a 2D freak wave looks much as a piece of a 1D freak wave, bounded in the transversal direction by two such dark solitons.

description: Let $ξ$ be a Dawson--Watanabe superprocess in $\mathbb{R}^d$ such that $ξ_t$ is a.s. locally finite for every $t\geq 0$. Then for $d\geq2$ and fixed $t>0$, the singular random measure $ξ_t$ can be a.s. approximated by suitably normalized restrictions of Lebesgue measure to the $\varepsilon$-neighborhoods of $\operatorname {supp}ξ_t$. When $d\geq3$, the local distributions of $ξ_t$ near a hitting point can be approximated in total variation by those of a stationary and self-similar pseudo-random measure $\tildeξ$. By contrast, the corresponding distributions for $d=2$ are locally invariant. Further results include improvements of some classical extinction criteria and some limiting properties of hitting probabilities. Our main proofs are based on a detailed analysis of the historical structure of $ξ$.

description: In a distributed storage system based on erasure coding, an important problem is the \emph{repair problem}: If a node storing a coded piece fails, in order to maintain the same level of reliability, we need to create a new encoded piece and store it at a new node. This paper presents a construction of systematic $(n,k)$-MDS codes for $2k\le n$ that achieves the minimum repair bandwidth when repairing from $k+1$ nodes.

description: We formulate a minimal ansatz for local stress distribution in a solid that includes the possibility of strongly anharmonic short-length motions. We discover a broken-symmetry metastable phase that exhibits an aperiodic, frozen-in stress distribution. This aperiodic metastable phase is characterized by many distinct, nearly degenerate configurations. The activated transitions between the configurations are mapped onto the dynamics of a long range classical Heisenberg model with 6-component spins and anisotropic couplings. We argue the metastable phase corresponds to a deeply supercooled non-polymeric, non-metallic liquid, and further establish an order parameter for the glass-to-crystal transition. The spin model itself exhibits a continuous range of behaviors between two limits corresponding to frozen-in shear and uniform compression/dilation respectively. The two regimes are separated by a continuous transition controlled by the anisotropy in the spin-spin interaction, which is directly related to the Poisson ratio $σ$ of the material. The latter ratio and the ultra-violet cutoff of the theory determine the liquid configurational entropy. Our results suggest that liquid's fragility depends on the Poisson ratio in a non-monotonic way. The present ansatz provides a microscopic framework for computing the configurational entropy and relaxational spectrum of specific substances.

Nuclear orientation studies at low temperatures
Creators: name: Daly, Patrick William
Publisher: name: University of British Columbia
Year: 2011

description: The interaction between the nuclear magnetic moment and the hyperfine field in ferromagnetic and antiferromagnetic materials has been used to orient radioactive nuclei at low temperatures. The measurement of the resulting angular distribution of the gamma radiation has yielded a variety of information in both nuclear and solid state physics. The ⁵⁹Fe nucleus in an iron sample has been studied in an attempt to verify a report by Tschanz and Sapp (1970) who measure an unexpectedly large effect in the gamma ray distribution from that nucleus oriented in double nitrate salts. Since in their experiment assumptions have to be made regarding the fraction of iron atoms in lattice sites, the well-defined environment of the iron lattice was chosen for the present experiment in order to permit an unambiguous interpretation of the results. In contradiction to predictions based on the work of Tschanz and Sapp, a null result was obtained at a temperature of 15 mK, indicating an upper limit for the magnetic moment of ⁵⁹Fe of |µ| < 0.9 µ[sub N. The anisotropy of gamma radiation emitted in the decay of ¹⁰³Ru oriented in ferromagnetic iron was measured to determine the magnetic moment of the isotope and to resolve mixing ratios in the decay scheme. The small effect observed at 11 mK permitted a lower limit to be placed on the magnetic moment: |µ| > 0.15 µ[sub N]. The sign of the E2/M1 mixing ratio for the 497 keV gamma transition was determined for the first time to be found negative. The techniques of nuclear orientation have also been used to observe the spin-flop transition in antiferromagnetic MnCl₂H₂O. By observing the gamma ray anisotropy in the decay of radioactive ⁵⁴Mn we find that at 60 mK the transition occurs for a critical field of H[sub c] = 6.50 ± 0.05 kG applied along the crystallographic c-axis. In the spin-flop phase, the electronic spins point at an angle of 71° to this axis. These data allow values of the molecular exchange and anisotropy fields to be determined yielding respectively H[sub E] = 11.7 ± 0.6 kG and H[sub A] = 2.0 ± 0.1 kG in agreement with the values reported by Miedema et al. (1965). This experiment demonstrates that nuclear orientation is a viable technique for studying spin-flop transitions and moreover allows the measurement of the directions of electronic spin magnetization in the spin-flop phase. The nuclear orientation of ²⁰⁷Bi in cobalt was studied to determine the hyperfine field. An unexpectedly small gamma ray anisotropy was observed. However, saturation of the effect occurred at a relatively high temperature. These results indicate that only a fraction (~12%) of the Bi nuclei felt a large hyperfine field (~600 kG). Presumably this was the fraction of atoms in lattice sites. Comparison of the anisotropics of the 1.064 MeV and the 1.761 MeV gamma rays shows that the former effect is enhanced, possibly because of the long half-life of the 1.633 MeV intermediate state.

title: The Minnesota Multiphasic Personality Inventory-2 and Low Back Pain Surgery Outcome
Creators: name: Shearer, David S.
Publisher: name: Utah State University
Year: 2001

description: Chronic back pain is a serious problem in the U.S. for which about 10% of back pain sufferers will undergo elective surgery. Unfortunately, back surgery is not successful in alleviating back pain in a substantial number of surgery patients. Various psychological and psychosocial variables have a demonstrated relationship to back surgery outcome. The most widely used personality test used to predict back surgery outcome is the Minnesota Multiphasic Personality Inventory (MMPJ). Past research has shown that elevations on three MMPI clinical scales (Hs, D, and Hy) are positively correlated with poor back surgery outcome. The current prospective study shows a similar pattern using the MMPI-2 to predict surgery outcome for 60 low back pain patients. It appears that past MMPI research in this area is applicable to the use of MMPI-2. These results also suggest that when MMPI-2 variables are combined with demographic and surgical variables, patients more likely to experience poor surgical outcome can be identified. There is evidence that elevations of the conversion V profile of the MMPI-2 may prospectively differentiate between successful and nonsuccessful surgery outcomes.

description: The COVID-19 lockdown in India saw a spate of news stories suggesting improvements in environmental conditions. In this article, we caution against optimistic narratives of environmental revival. First, we analyse air pollution data before and during the lockdown to show that these improvements were temporary and a by-product of the severe restrictions placed on the normal functioning of the economy. Second, drawing upon data on income and inequality, we suggest that the human suffering witnessed during the lockdown was a result of widening social disparities since the 1990s. We argue that environmental priorities cannot be separated from social concerns, and equity has to be at the centre of imagining sustainability beyond the pandemic.

The structure of convection in the planetary boundary layer
Creators: name: Davison, Douglas Stewart
Publisher: name: University of British Columbia
Year: 2011

description: During July 1971, an intensive experimental program was undertaken in south-eastern Alberta to measure the turbulent statistics in the planetary boundary layer using a 92m tower, an array of four smaller towers and an instrumented T-33 aircraft from the National Aeronautical Establishment of the National Research Council. The height variation of the high wavenumber spectral levels of temperature and vertical velocity were found to follow the z-dependence predicted by semi-empirical theories applicable to the constant flux layer up to a height of at least 300m. However, unlike the constant flux layer, the assumption of Ri = z/L is not applicable at higher levels; thus, at large z, the spectral levels in the k[sup -5/3] region for temperature and vertical velocity have the form, Φ[sub TT] ∝z and Φ[sub ww] ∝z°. The translation velocity of convective plumes was measured with an array of towers, at a height of 3.5m. The direction of plume motion was found to be close to that of the surface wind. The speed of plume motion was found to be close to the wind speed near the top of the surface shear zone; this result is different from previous estimates using different techniques. A dynamic model of the plume was used to show that a translation speed close to the wind speed near the top of the surface shear zone (as observed) allows plumes to exist at a lower thermal instability level then any other possible translation speed. The horizontal cross-sectional shape of the temperature field of the plumes at 3.5m was observed to be very elongated in the downwind direction with a ratio of the downstream to cross-stream diameters of about 8:1. This shape was dynamically justified.
A thesis submitted to the University of Tasmania
Creators: name: Nillsen, RV
Publisher: name: University Of Tasmania
Year: 2023

description: The thesis consists of two volumes. Volume I comprises work in various areas of mathematical analysis, especially abstract harmonic analysis, differential equations and moment problems. Volume II comprises work primarily in harmonic analysis, especially work on the Fourier transform, invariant linear forms, and associated phenomena. The ideas in this work have had a long period of gestation, although the fuller development and expression of them has occurred over a relatively short and intense period. The dominant ideas emerged in an endeavour to answer the following question: if f is a function in L2(IRn), how can the behaviour of its Fourier transform near the origin of IRn be described and characterized? The corresponding question for the circle group had been given a satisfactory answer by Gary Meisters and Wolfgang Schmidt in 1972, so the work also can be regarded as arising from an attempt to extend their result from the compact case of the circle group to the non-compact case of IRn. The answers presented to these and related questions have implications for other areas of analysis; the notable ones being the ranges of partial differential operators, and the behaviour of some of the singular integral operators of classical analysis.

A theoretical study of the direct radiative capture reaction 16O(p,[gamma])17F
Creators: name: Chow, H. C.
Publisher: name: University of British Columbia
Year: 2011

description: The radiative capture reaction ¹⁶0(p,γ)¹⁷F has been studied theoretically using a two-body model to estimate the capture cross sections. The ¹⁶0(p,γ)¹⁷F reaction is a direct capture process at low energies, which is of astrophysieal interest•because of its role in the C-N-0 bi-cycle responsible for hydrogen burning in the larger main sequence stars. The analysis done in this thesis involves a de- tailed fitting of the ¹⁶0(p,p)¹⁶0 scattering data to search for the parameters of a Saxon Woods potential with an energy dependent central well depth, which best describes the ¹⁶0+p interaction. The best set of parameters obtained is used to generate the initial continuum and bound state wave functions. The matrix elements of the electromagnetic interaction hamiltonian are calculated and first order time dependent perturbation theory is used to- obtain the capture cross sections. The results are compared with recent experimental data, observed by T. Hall (1973), from 0.78 Mev to 2.3 Mev, which has a significantly higher accuracy than previous data that was available. The angular distributions predicted by the theory agree satisfactorily with Hall's data. The astrophysieal S-factor extrapolated to thermal energies has the value 8.53 kev-barn at 10 kev, with an uncertainty of at least 5%„ Some of the methods used in the ¹⁶0(p,γ)¹⁷F calculations are applied to a somewhat different capture reaction ⁶Li(p,γ)⁷Be, which involves interferences with resonance capture. This is included in an appendix; and because of the limited experimental data on this reaction, the results are much less conclusive.

description: Diabetes mellitus is a serious problem that affects 15.7 million individuals in the United States. The complications of this disease are catastrophic and can lead to blindness, kidney disease, lower limb amputations, nerve damage, increased risk of heart disease, stroke, and death. Among Native Americans, diabetes has reached epidemic proportions. A variety of psychosocial variables has demonstrated relationships to diabetic outcome. Past research has shown a relationship between psychological variables and glucose control. The current study of Native Americans shows a similar pattern using the psychosocial instruments to measure the constructs of depression, anger, hostility, social support, and perceived stress. Participants for this study were part of the Strong Heart Study and were 512 Native Americans from tribes in South Dakota and Oklahoma between the ages of 46 - 77. This study shows a relationship between the variables of anger, depression and hostility, and glyciemic control. A relationship between social support, perceived stress, and depression was found to be related to reported quality of life in participants who were either diabetic or had impaired glucose tolerance.
title: An Evaluative Argument-Based Investigation of Validity Evidence for the Utah Pre-Algebra Criterion-Referenced Test
Creators: name: Moulding, Louise Richards
Publisher: name: Utah State University
Year: 2001

description: This study collected evidence to address the assumptions underlying the use of the Utah Core Assessment to Pre-Algebra (UCAP) to (a) measure student achievement in pre-algebra, and (b) assist teachers in making adjustments to instruction. An evaluative argument was defined to guide the collection of evidence. Each of the assumptions in the evaluative argument was addressed using data from a suburban northern Utah school district. To collect the evidence, test content was examined including item match to course objectives, reliability, and subtest intercorrelations. Analyses of correlations of the UCAP with convergent and discriminant measures were completed using student test data (N = 1,461), including an examination of both the pattern of correlations and tests of statistical significance. Pre-algebra teachers (N = 12) were interviewed to ascertain the degree to which UCAP results were used to make necessary adjustments to instruction.
It was found that the UCAP was technically sound, but measured only 65% of course objectives. Correlation coefficients were analyzed using pattern comparisons and tests of statistical significance. It was found that the pattern of correlation coefficients and the distinction of convergent and discriminant measures supported the UCAP as a measure of mathematics. Teacher interview data revealed that teachers did not make substantive adjustments to the instruction of pre-algebra based on test scores.
Based on these results it was concluded that the underlying assumptions concerning the use of the UCAP were not fully supported. The lack of complete coverage of the pre-algebra course objectives calls into question the ability of the UCAP scores to be used as measures of student achievement, in spite of the technical quality of the test. There was support for the assumption that the UCAP measures mathematics. There was little evidence that teachers use the UCAP score reports to make meaningful and appropriate adjustments to instruction. More evidence is needed to understand the factors that may have led to this lack of use.
The evaluative argument framework defined in this study provides guidance for future research to collect evidence of the validity of decisions based on UCAP scores.

description: This cumulative dissertation summarizes and discusses six research articles that are either published in academic journals and conference proceedings or submitted for review. The topics described are cross-disciplinary and can be allocated to Accounting, Finance, and Information Systems Research. In Accounting, we analyze the methodological differences between ratings and lifetime default risk to develop a proof for the use of rating changes for the determination of significant increases in credit risk in accordance to the impairment requirements of the International Financial Reporting Standards. Our results and findings contribute to more transparency with regard to decision-relevant information for stakeholders of financial statements. In Finance, we combine machine learning techniques with cointegration analysis to produce adequate projections of macroeconomic variables for stress testing exercises. Our results and findings have practical relevance for risk managers in the financial services industry and help to validate the execution of stress tests and to ensure compliance. In Information Systems Research, we develop a general process model and visualization framework to identify and highlight unusual data in subsets for further investigation. Our process model and visualization framework empower domain experts and data analysts to jointly gain and discuss insights from underlying data. Our results and findings show that both our process model and visualization framework contribute to interactive visual analytics, storytelling, and well-founded decision support.
title: Assessing the Need for Evaluator Certification

description: Professional certification is arguably a means of validating a practitioner's competency within their trade. Certification can also be beneficial for enhancing a profession's prestige, improving academic programs, and helping to define the profession in question. However, certification can be considered not feasible, effective, or perhaps even necessary. Due to the likelihood of these conflicting viewpoints, it is essential for any profession to determine the support level from its members prior to implementing a certification process.
This thesis presents the results from a 1998 survey for the American Evaluation Association, whereby their members responded to items regarding the need, effectiveness, feasibility of enacting a certification system for professional evaluators. Respondents were mixed in their attitudes. A slight majority indicated a certification system could be feasible. However, more respondents were unconfident than confident that certification can be effective or is even necessary; additionally, many were undecided on these issues.
title: The Anatomy of Virtual Manipulative Apps: Using Grounded Theory to Conceptualize and Evaluate Educational Apps that Contain Virtual Manipulatives

description: This exploratory qualitative study used grounded theory to investigate the anatomy of educational apps that contain virtual manipulatives. For this study 100 virtual manipulatives within educational apps designed for the iPad were observed by the researcher in order to expand the explanations of and build theory about virtual manipulatives within apps. Affordance theory was used to frame all six phases of the study in which the researcher identified virtual manipulatives situated within educational apps, conducted observer-as-participant structured and unstructured observations, analyzed component data including field notes and memos using open and axial coding, created a conceptual framework, developed an evaluation tool prototype to evaluate virtual manipulatives within educational apps, and used the evaluation tool prototype to evaluate additional virtual manipulatives within educational apps.
The constant comparative method of open and axial coding was used to analyze the observation data that included field notes, memos, and video recordings. This indepth qualitative analysis led to the emergence of six study results concerning the components and relationships within educational apps that contain virtual manipulatives. The results revealed that: (1) virtual manipulatives within apps are comprised of two components: dynamic mathematical objects and features; (2) there are three distinct types of dynamic mathematical objects; (3) there are eight categories of features; (4) within one virtual manipulative there can be one or multiple objects; (5) varying relationships can exist among the dynamic object and the features within a virtual manipulative; and (6) varying relationships can exist among the virtual manipulatives within an education app in terms of the number, type, and ways the user proceeds.
A conceptual framework was also developed during the study to illustrate the components and relationships that emerged from the analysis and to serve as the basis for the development of an evaluation tool prototype to evaluate educational apps that contain virtual manipulatives. The components, relationships, framework, and evaluation tool prototype developed during this study advance the literature on virtual manipulatives and provide researchers with a common language to evaluate these apps.
title: Addressing Disruptive Behaviors in the Preschool Classroom: An Adaptation of Parent-Child Interaction Therapy (PCIT) for Head Start Teachers
Creators: name: Collett, Brent R.
Publisher: name: Utah State University

description: Several researchers have begun to investigate early intervention and prevention programs, seeking to alter the trajectory of early-onset behavior problems. While it appears that multi-modal programs are the most promising approach, researchers have only recently begun to evaluate programs that use a similar treatment approach across settings and there is currently little information about classroom-based treatments for disruptive behaviors among preschoolers. The purpose of this study was to develop a classroom-based intervention based on the Parent-Child Interaction Therapy (PCIT) model developed by Eyberg. In addition, this study provides an initial investigation of the efficacy of this program with an emphasis on evaluating changes in teacher behavior and treatment acceptability. The intervention was provided to a group of 26 teachers from 13 Head Start classrooms. Results indicated minimal changes in observed teaching behavior and no significant changes in teachers' self-efficacy. Although the intervention was rated as being acceptable by teachers overall, ratings were somewhat lower for sessions dealing with child-directed activities; teacher comments indicated that this component was difficult to implement in the classroom. Observations of child behavior indicated reductions in both prosocial and disruptive behaviors. Teacher-completed rating scales indicated statistically significant reductions in disruptive child behaviors and child behavior problems, although the magnitude of these changes was generally small. The implications of these findings will be discussed and modifications will be proposed for increasing the effectiveness and acceptability of this intervention.

Machine learning

description: Deep Learning (DL) applications have tremendous computation requirements, making running them on traditional computers (CPUs) very inefficient. Modern computer systems deploy hardware acceleration, which involves offloading compute-intensive and memory-intensive tasks to specialized hardware. In the space of hardware acceleration alternatives, Field Programmable Gate Arrays (FPGAs) lie in the middle of the programmability-efficiency spectrum, with Graphic Processing Units (GPUs) being more programmable and Application Specific Integrated Circuits (ASICs) being more efficient. FPGAs provide massive parallelism and are reconfigurable, which makes them very well suited for the fast-changing needs of DL applications. However, the generic building blocks available on traditional FPGAs limit the acceleration that can be achieved. Hence, FPGAs trail ASICs by an order of magnitude in terms of performance. So, how can the gap between ASICs and FPGAs be minimized, while retaining the strength of FPGAs - the reconfigurability? This dissertation describes research that aims to find the answer to this question by proposing new domain-optimized FPGAs for Deep Learning. The key idea is to integrate new hardware blocks to the FPGA that provide domain-specialized functionality, while still keeping them largely general and allowing them to be used with traditional FPGA flows. Specifically, new DL-optimized FPGAs containing blocks called Tensor Slices and CoMeFa RAMs are presented. The architecture of these blocks, along with the tradeoffs in exploring their architectures, is explained. Results show that significant performance improvement and energy reduction can be obtained for DL applications by using DL-specialized FPGAs containing these blocks. New benchmarks, called Koios, developed to explore FPGA architectures for DL are also explained. These benchmarks are open-sourced and work with VTR (an academic open source FPGA architecture exploration tool). New DL-optimized FPGAs, containing Tensor Slices and CoMeFa RAMs, are significantly more efficient at accelerating DL workloads, while still being reconfigurable at a fine-grain. With the abundance of DL applications, making DL-optimized FPGAs is an attractive proposition.

Topological edge modes

description: Topological edge modes within gapped 2D electron systems have emerged as significant focal points of study, being seen as fundamental components for building topological qubits. Their physical location and geometric properties present crucial facets for applications, whose investigation remains largely untouched. This gap underscores the need for innovative techniques capable of executing nanoscale conductivity measurements at ultra-low temperatures. In this dissertation, I commence with the development of a cutting-edge microwave impedance microscopy system in a dilution refrigerator. Subsequently, I present the observation of chiral edge modes in magnetically doped (Bi, Sb)₂Te₃ thin films and the helical edge modes in monolayer WTe₂ devices at temperatures approximating 100 mK. This research sets a substantial precedent for the exploration of mesoscopic quantum phenomena under extreme temperature conditions and paves the way for leveraging microwave nanoscopy within the realm of quantum information science.
The effects of speaking style, noise, and semantic context on speech segmentation : evidence from artificial language learning and eye-tracking experiments

description: This dissertation reports a series of three experimental studies that investigated how variation in speech clarity and intelligibility as well as the presence of semantic context affects listeners’ speech segmentation. An artificial language learning experiment in Study 1 (Chapter 2) showed that speaking clearly relative to speaking conversationally improved segmentation of nonsense words by statistical learning. However, the improvement was observed only in the quiet listening condition but not in noise. Using the visual-world eye-tracking paradigm, Study 2 (Chapter 3) examined the clear speech segmentation benefit during real-time processing of meaningful sentences in which the target word was temporarily ambiguous with a competitor across a word boundary. The results revealed that that relative to conversational speech, clear speech facilitated target word segmentation even before the target and competitor could be disambiguated based on phonemic information. The facilitation not only emerged in quiet but also extended to the noisy listening condition. Finally, built upon Study 2, Study 3 (Chapter 4) employed eye-tracking to further explore how such clear speech facilitation effect is modulated by semantic cues from the preceding context. It was found that while the clear speech segmentation benefit was eliminated when the context already biased listeners towards the target, it was still present when the context favored the unintended competitor. Taken together, the key findings from the three studies advance the understanding of the relative importance of signal-dependent and signal-independent sources of information during segmentation in realistic communicative settings. The results also provide novel insight into the well-documented clear speech processing benefits by demonstrating that improved segmentation may in part underlie these benefits. The dissertation also has theoretical implications, suggesting directions for refining the current spoken word recognition and segmentation models.
