description: We propose a versatile platform to investigate the existence of Majorana bound states (MBSs) and their non-Abelian statistics through braiding. This implementation combines a two-dimensional electron gas formed in a semiconductor quantum well grown on the surface of an s-wave superconductor with a nearby array of magnetic tunnel junctions (MTJs). The underlying magnetic textures produced by MTJs provide highly controllable topological phase transitions to confine and transport MBSs in two dimensions, overcoming the requirement for a network of wires. Obtained scaling relations confirm that various semiconductor quantum well materials are suitable for this proposal.

description: An organocatalytic three-component reductive coupling reaction between dimethyl phosphite, benzylidene pyruvates, and aldehydes is reported. A chiral triaryliminophosphorane catalyst promotes Pudovik addition, which is followed by phospha-Brook rearrangement to transiently generate enolates that are trapped stereoselectively by aldehydes. This reductive coupling provides vicinal polyfunctionalized stereocenters from readily available prochiral starting materials with excellent diastereoselectivity, enantioselectivity, and yield.

description: This is a scanned copy of a document, including photographs, on the population dynamics of Erica ardens in Swellendam State Forest, Langeberg, site 3320CD/2. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape. SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).

description: The recent groundbreaking demonstrations of quantum supremacy in noisy intermediate scale quantum (NISQ) computing era has triggered an intense activity in establishing finer boundaries between classical and quantum computing. In this dissertation, we use established techniques based on quantum Monte Carlo (QMC) to map quantum problems into probabilistic networks where the fundamental unit of computation, p-bit, is inherently probabilistic and can be tuned to fluctuate between ‘0’ and ‘1’ with desired probability. We can view this mapped network as a Boltzmann machine whose states each represent a Feynman path leading from an initial configuration of q-bits to a final configuration. Each such path, in general, has a complex amplitude, ψ which can be associated with a complex energy. The real part of this energy can be used to generate samples of Feynman paths in the usual way, while the imaginary part is accounted for by treating the samples as complex entities, unlike ordinary Boltzmann machines where samples are positive. This mapping of a quantum circuit onto a Boltzmann machine with complex energies should be particularly useful in view of the advent of special-purpose hardware accelerators known as Ising Machines which can obtain a very large number of samples per second through massively parallel operation. We also demonstrate this acceleration using a recently used quantum problem and speeding its QMC simulation by a factor of ∼ 1000× compared to a highly optimized CPU program. Although this speed-up has been demonstrated using a graph colored architecture in FPGA, we project another ∼ 100× improvement with an architecture that utilizes clockless analog circuits. We believe that this will contribute significantly to the growing efforts to push the boundaries of the simulability of quantum circuits with classical/probabilistic resources and comparing them with NISQ-era quantum computers.
Adaptive Optimization Methods for Machine Learning

subject: FOS: Mathematics

description: This thesis studies the adaptive optimization algorithms to solve convex and non-convex optimization problems in machine learning. Specifically, we focus on the utilization of adaptive step sizes and adaptive sampling in gradient-based optimization methods. In the first part of this thesis, we analyze the algorithmic stability of the well-known adaptive optimization methods such as Adagrad, RMsprop,. . . , which utilize the adaptivity of the step sizes to speed up convergence. Algorithmic stability measures the sensitivity of a learning algorithm with the change of data, which can be used as an upper bound for the learning algorithm’s generalization. Previously, there was much research on the algorithmic stability of Stochastic Gradient Descent and Stochastic Gradient Descent with Momentum. However, there is no similar result for adaptive optimization methods. This work is an attempt to bridge this gap. We show that under some mild conditions on hyper-parameters, the adaptive optimization methods are uniformly stable. This work also provides some insights on choosing hyper-parameters for those methods that are important in practice. In the second part of this thesis, we design a novel adaptive sampling Stochastic Variance Reduced Gradient method to solve convex and non-convex optimization problems in the distributed setting. Our new method reduces the dependence on the Lipschitz constants, which improves the convergence rate of the Stochastic Variance Reduced method. One novel aspect of our method compared to the previous state of the art is that our method does not need any prior knowledge about Lipschitz constants of local loss functions.

description: Increasing the speed of cache simulation to obtain hit/miss rates en- ables performance estimation, cache exploration for embedded sys- tems and energy estimation. Previously, such simulations, particu- larly exact approaches, have been exclusively for caches which uti- lize the least recently used (LRU) replacement policy. In this paper, we propose a new, fast and exact cache simulation method for the First In First Out(FIFO) replacement policy. This method, called DEW, is able to simulate multiple level 1 cache configurations (dif- ferent set sizes, associativities, and block sizes) with FIFO replace- ment policy. DEW utilizes a binomial tree based representation of cache configurations and a novel searching method to speed up sim- ulation over single cache simulators like Dinero IV. Depending on different cache block sizes and benchmark applications, DEW oper- ates around 8 to 40 times faster than Dinero IV. Dinero IV compares 2.17 to 19.42 times more cache ways than DEW to determine accu- rate miss rates.

description: Through site-directed mutagenesis targeted at identification of the catalytic base in the rice (Oryza sativa) syn-copalyl diphosphate synthase OsCPS4, changes to a single residue (H501) were found to induce rearrangement rather than immediate deprotonation of the initially formed bicycle, leading to production of the novel compound syn-halimadienyl diphosphate. These mutational results are combined with quantum chemical calculations to provide insight into the underlying reaction mechanism.

description: This thesis presents an investigation of the evolution of supermassive black holes (SMBHs) and galaxies through cosmological hydrodynamic simulations on petascale supercomputers. With the large volume, high-resolution cosmological simulation BlueTides and ASTRID, we study the local and large scale environment of the first quasars, mass assembly and dynamics of the SMBHs over cosmic history, as well as the interplay between SMBHs and galaxy formation. We also diagnose the high redshift galaxy population predicted by cosmological simulations, and use current and future observations of high redshift galaxy abundance to test the alternative dark matter models such as the fuzzy dark matter. Finally, we also explore the possibility of using deep learning methods to model the small scale physical process for larger volume simulations, as a potential way to further extend the dynamic range that can be covered by next generation cosmological simulations.

description: The covariant and kappa-symmetric action for superstring in direct product of two flat D=10 N=1 superspaces is presented. It is given by the sum of supersymmetric generalization of two copies of chiral boson actions constructed with the use of the Pasti-Sorokin-Tonin (PST) technique. The chirality of 8 `left' bosons and 8 `left' fermions and the anti-chirality of their `right' counterparts are obtained as gauge fixed version of the equations of motion, so that the physical degrees of freedom are essentially those of the II Green-Schwarz superstring. Our action is manifestly T-duality invariant as the fields describing oscillating and winding modes enter it on equal footing.

On Adjoint and Brain Functors

Subjects: subject: Category Theory (math.CT)

description: There is some consensus among orthodox category theorists that the concept of adjoint functors is the most important concept contributed to mathematics by category theory. We give a heterodox treatment of adjoints using heteromorphisms (object-to-object morphisms between objects of different categories) that parses an adjunction into two separate parts (left and right representations of heteromorphisms). Then these separate parts can be recombined in a new way to define a cognate concept, the brain functor, to abstractly model the functions of perception and action of a brain. The treatment uses relatively simple category theory and is focused on the interpretation and application of the mathematical concepts. The Mathematical Appendix is of general interest to category theorists as it is a defense of the use of heteromorphisms as a natural and necessary part of category theory.
Reducing Organizational Rule Breaking Through Task Variety: How Task Design Supports Deliberative Thinking
Creators: name: Moore, Celia
name: Derfler-Rozin, Rellie
name: Staats, Bradley R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: In this paper we argue that task design affects rule breaking in the workplace. Specifically, we propose that task variety activates deliberative (Type 2) processes as opposed to automatic/intuitive (Type 1) processes, which, in turn, helps prevent individuals from breaking rules in order to serve their own hedonic self-interest. We use data from the home loan application processing operations of a Japanese bank to establish the phenomenon in the field. We document that increased task variety at a daily level is associated with lower levels of rule breaking in the form of violating corporate break time policies (Study 1). We further explore the relationship between task variety and rule breaking in three lab experiments, using different operationalizations of rule breaking (Studies 2, 3a, and 3b) and provide direct evidence for the mediating effect of deliberative thinking in this relationship (Studies 3a and 3b). We discuss implications for rule compliance in organizations, behavioral ethics, and work design.
Estimating Pore Water Electrical Conductivity of Sandy Soil from Time Domain Reflectometry Records Using a Time-Varying Dynamic Linear Model

description: Despite the importance of computing soil pore water electrical conductivity (σp) from soil bulk electrical conductivity (σb) in ecological and hydrological applications, a good method of doing so remains elusive. The Hilhorst concept offers a theoretical model describing a linear relationship between σb, and relative dielectric permittivity (εb) in moist soil. The reciprocal of pore water electrical conductivity (1/σp) appears as a slope of the Hilhorst model and the ordinary least squares (OLS) of this linear relationship yields a single estimate ( 1/σpˆ ) of the regression parameter vector (σp) for the entire data. This study was carried out on a sandy soil under laboratory conditions. We used a time-varying dynamic linear model (DLM) and the Kalman filter (Kf) to estimate the evolution of σp over time. A time series of the relative dielectric permittivity (εb) and σb of the soil were measured using time domain reflectometry (TDR) at different depths in a soil column to transform the deterministic Hilhorst model into a stochastic model and evaluate the linear relationship between εb and σb in order to capture deterministic changes to (1/σp). Applying the Hilhorst model, strong positive autocorrelations between the residuals could be found. By using and modifying them to DLM, the observed and modeled data of εb obtain a much better match and the estimated evolution of σp converged to its true value. Moreover, the offset of this linear relation varies for each soil depth.

description: Superconductors derived from topological insulators and topological crystalline insulators by doping have long been considered to be candidates as topological superconductors. Pb$_{0.5}$Sn$_{0.5}$Te is a topological crystalline insulator with mirror symmetry protected surface states on (001), (011) and (111) oriented surfaces. The superconductor (Pb$_{0.5}$Sn$_{0.5}$)$_{0.7}$In$_{0.3}$Te is induced by In doping in Pb$_{0.5}$Sn$_{0.5}$Te, and is thought to be a topological superconductor. Here we report the first scanning tunneling spectroscopy measurement of the superconducting state as well as the superconducting energy gap in (Pb$_{0.5}$Sn$_{0.5}$)$_{0.7}$In$_{0.3}$Te on a (001)-oriented surface. The spectrum can be well fitted by an anisotropic $s$-wave gap function of $Δ=0.72+0.18\cos4θ$ meV using Dynes model. The results show that the quasi-particle density of states seem to be fully gapped without any in-gap states, in contradiction with the expectation of a topological superconductor.

description: In this note we study a class of one-dimensional Ising chain having a highly degenerated set of ground-state configurations. The model consists of spin chain having infinite-range pair interactions with a given structure. We show that the set of ground-state configurations of such a model can be fully characterized by means of symbolic dynamics. Particularly we found that the set ground- state configurations defines what in symbolic dynamics is called sofic shift space. Finally we prove that this system has a non-vanishing residual entropy (the topological entropy of the shift space), which can be exactly calculated.

description: Supersymmetric versions of induced-gravity inflation are formulated within Supergravity (SUGRA) employing two gauge singlet chiral superfields. The proposed superpotential is uniquely determined by applying a continuous R and a discrete Z_2 symmetry. We also employ a logarithmic Kahler potential respecting the symmetries above and including all the allowed terms up to fourth order in powers of the various fields. When the Kahler manifold exhibits a no-scale-type symmetry, the model predicts spectral index ns=0.963 and tensor-to-scalar r=0.004. Beyond no-scale SUGRA, ns and r depend crucially on the coefficient ksphi involved in the fourth order term, which mixes the inflaton Phi with the accompanying non-inflaton superfield S in the Kahler potential, and the prefactor encountered in it. Increasing slightly the latter above (-3), an efficient enhancement of the resulting r can be achieved putting it in the observable range favored by the Planck and BICEP2/Keck Array results. In all cases, imposing a lower bound on the parameter cR, involved in the coupling between the inflaton and the Ricci scalar curvature, inflation can be attained for subplanckian values of the inflaton while the corresponding effective theory respects the perturbative unitarity.

Recently, near-infrared (NIR) fluorescent proteins (FPs) engineered from bacterial phytochromes binding biliverdin IXα (BV), such as the iRFP series, have become invaluable probes for multicolor fluorescence microscopy and in vivo imaging. However, all current NIR FPs suffer from relatively low brightness. Here, by combining biochemical, spectroscopic and resonance Raman (RR) assays, we purified and characterized an iRFP variant that contains a BV chromophore simultaneously bound to two cysteines. This protein with the unusual double-Cys attached BV showed the highest fluorescence quantum yield (FQY) of 16.6% reported for NIR FPs, whereas the initial iRFP appeared to be a mixture of species with a mean FQY of 11.1%. The purified protein was also characterized with 1.3-fold higher extinction coefficient that together with FQY resulted in almost two-fold brighter fluorescence than the original iRFP as isolated. This work shows that the high FQY of iRFPs with two cysteines is a direct consequence of the double attachment. The PAS-Cys, GAF-Cys and double-Cys attachment each entails distinct configurational constraints of the BV adduct, which can be identified by distinct RR spectroscopic features, i.e. the marker band including the C=C stretching coordinate of the ring A-B methine bridge, which was previously identified as being characteristic for rigid chromophore embedment and high FQY. Our findings can be used to rationally engineer iRFP variants with enhanced FQYs.

description: BACKGROUND: The Orphan Drug Act is an important piece of legislation that uses financial incentives to encourage the development of drugs that treat rare diseases. This analysis studies the effects of a portion of the Orphan Drug Act, the orphan drug designation. Specifically, it studies the value that investors place on the orphan drug designation, by investigating how investors react to companies' announcing that their product has received the designation.

RESULTS: The results, on average, show that the stock price of a company increases by 3.36% after the announcement of the designation, increasing the value of the company. The results are more pronounced for oncology drugs, and drugs being developed by the smallest companies.

CONCLUSION: The orphan designation appears to be successful at generating positive value for companies, as seen by the positive and significant average increases in stock price.

description: This is a scanned copy of erosion monitoring in Sonderend, Langeberg, site 3319DB/5. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape. SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).

description: We report on the development of a novel FPGA-based Time-to-Digital Converter and its implementation in a detection chain that records the coordinates of single particles along three dimensions. The detector is composed of Micro-Channel Plates mounted on top of a cross delay line and connected to fast electronics. We demonstrate continuous recording of the timing signals from the cross delay line at rates up to 4.1x10^6 per second and three-dimensional reconstruction of the coordinates up to 3.2x10^6 particles per second. From the imaging of a calibrated structure we measure the in-plane resolution of the detector to be 140(20) um. In addition we analyze a method to measure the resolution without placing any structure under vacuum, a significant practical improvement. While we use UV photons here, the results of this work directly apply to the detection of other kinds of particles.

description: Classification problems, such as determining when two topological spaces are the same, are central to many fields of mathematics. Invariant descriptive set theory provides a framework with which to measure and compare the difficulty of these problems, which can help determine if certain methods are strong enough to approach them. In this thesis, we study the classification problems which are induced by continuous actions of Polish groups on Polish spaces, which includes most problems arising naturally in other fields of mathematics. After an introductory chapter, we prove in Chapters 2 and 3 that there are interesting equivalence relations which are classifiable by CLI Polish groups but not by TSI Polish groups. The main example arises from the group-jump operation of Clemens-Coskey. We also give a characterization of generic ergodicity with respect to equivalence relations classifiable by non-Archimedean TSI Polish groups, as well as characterize the potential Borel complexity spectrum of equivalence relations classifiable by such groups. In Chapter 4, we show that every countable treeable equivalence relation is classifiable by an abelian Polish group, answering a question of Hjorth in the negative. This provides some progress towards separating classifiability by TSI Polish groups and by abelian Polish groups, and suggests that this is a subtle problem. In the next two chapters, we study the tame abelian Polish groups. In Chapter 5 show that there is an abelian product group which is D(Π 0/5)-tame but not Π 0/5-tame, answering a question of Ding-Gao. In Chapter 6 we show that there is a tame abelian Polish group which is universal among the tame non-Archimedean abelian Polish groups, answering another question of Ding-Gao. Finally, in Chapter 7, we give an expository chapter on the Gandy-Harrington topology, a recursion-theoretic tool used in several dichotomy results in the field. Streamlined proofs are given for Hjorth’s dichotomies for turbulence and essential countability, while isolating and abstracting the recursion-theoretic components as much as possible.

description: Abstract Background Newborn screening for mucopolysaccharidosis type I (MPS I) shows promise to improve outcomes by facilitating early diagnosis and treatment. However, diagnostic tests for MPS I are of limited value in predicting whether a child will develop severe central nervous system disease associated with Hurler syndrome, or minimal or no central nervous system involvement associated with the attenuated phenotypes (Hurler–Scheie and Scheie syndromes). Given that the optimal treatment differs between Hurler syndrome and the attenuated MPS I phenotypes, the absence of a reliable prognostic biomarker complicates clinical decision making for infants diagnosed through newborn screening. Information about the natural history of Hurler syndrome may aid in the management of affected infants, contribute to treatment decisions, and facilitate evaluation of treatment effectiveness and prognosis. Thus, the aim of this study was to characterize the progression and timing of symptom onset in infants with Hurler syndrome. Results Clinical data from 55 patients evaluated at a single center were retrospectively reviewed. Information about each child’s medical history was obtained following a standardized protocol including a thorough parent interview and the review of previous medical records. All patients underwent systematic physical and neurodevelopmental evaluations by a multidisciplinary team. Nearly all patients (98%) showed signs of disease during the first 6 months of life. Common early disease manifestations included failed newborn hearing screen, respiratory symptoms, difficulty latching, and otitis media. Other symptoms such as kyphosis, corneal clouding, cardiac disease, joint restrictions, and enlarged head circumference typically appeared slightly later (median age, 8–10 months). During the first 12 months, gross motor development was the most severely affected area of functioning, and a significant number of patients also experienced language delays. Cognition was typically preserved during this period. Conclusions In this large cohort of patients with Hurler syndrome, the vast majority showed signs and symptoms of disease during the first months of life. More research is needed to determine the extent to which early clinical manifestations of MPS I can predict phenotype and treatment outcomes.
