Analysis of a complexity-based pruning scheme for classification trees
Creators: name: Nobel, Andrew B.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: A complexity based pruning procedure for classification trees is described, and bounds on its finite sample performance are established. The procedure selects a subtree of a (possibly random) initial tree in order to minimize a complexity penalized measure of empirical risk. The complexity assigned to a subtree is proportional to the square root of its size. Two cases are considered. In the first the growing and pruning data sets are identical, and in the second they are independent. Using the performance bound, the Bayes risk consistency of pruned trees obtained via the procedure is established when the sequence of initial trees satisfies suitable geometric and structural constraints. The pruning method and its analysis are motivated by work on adaptive model selection using complexity regularization.

description: To review the effects of external lumbar supports on various aspects of sensorimotor function including joint position sense (JPS), postural control, anticipatory postural adjustments (APAs), and compensatory postural adjustments (CPAs). A systematic literature search was performed in PubMed, EMBASE, Scopus, Ovid, Cochrane library, and Web of Science. Two reviewers selected studies which assessed the effect of lumbosacral orthosis or kinesio-tape on JPS, postural control or APAs/CPAs in subjects with and without low back pain (LBP). The methodological quality of included studies was assessed using a modified version of Downs and Black’s checklist. Findings demonstrated moderate effects of lumbosacral orthosis on specific aspects of sensorimotor control including JPS and to a lesser extent standing stability. These domains were not or minimally affected by application of kinesio-tape. Both orthosis and kinesio-tape had negligible effects on APAs and CPAs. The positive effects of lumbar orthosis on JPS or postural control were mostly observed in conditions where sources of proprioceptive feedback are impaired (such as LBP) or absent (standing with eyes closed on an unstable surface). However, evidence does not prove significant positive effects for the application of kinesio-tape to improve sensorimotor control.IMPLICATIONS FOR REHABILITATIONWearing lumbar orthosis leads to an improvement in joint position sense.Postural stability seems to be affected to some extent by utilizing lumbar orthosis.Clinicians can administer orthosis to improve sensorimotor adaptation, especially in conditions with poor proprioception.Kinesio-tape had negligible effects on all domains of sensorimotor control.Improvement of sensorimotor function as a result of application of kinesio-tape is questionable.

description: R&E-SOURCE 14/2020: Im Fokus der pädagogischen Entwicklungslehre steht das Verständnis von Lernen sowie die Selbstwerdung und Selbstgestaltung über die Lebensspanne. Die Entwicklungspädagogik ist eine interdisziplinäre Aufgabe und führt zu einer Integrativen Pädagogischen Anthropologie. Die Pädagogik ermöglicht durch das Zusammenspiel und der Wechselbeziehung von Bildung und Erziehung eine umfassende Einsicht in die menschliche Entwicklung durch den Blick auf Zusammenhänge, Beziehungen und Wechselwirkungen, insbesondere durch den besonderen Blick auf das durch Lernprozesse Veränderliche. Die Entwicklungspädagogik formuliert die aus unterschiedlichen Perspektiven vorliegenden Forschungsfragen wie auch die Einsichten in die Entwicklung des Menschen in pädagogische Fragestellungen um und führt die Erkenntnisse durch eine pädagogische Rekontextualisierung in die Lebenswelt und Praxis zurück. Der vorliegende Beitrag widmet sich dem Verständnis wie auch dem Fokus auf diejenigen Aspekte der menschlichen Entwicklung, die alles menschliche Lernen wie auch das Vermögen der Empathie und Kooperation begründen. Im Besonderen setzt sich der Beitrag mit der Entwicklung der Emotionen und deren Zusammenwirken auseinander.

description: We design an algorithmic framework using matrix exponentials for time-domain simulation of power delivery network (PDN). Our framework can reuse factorized matrices to simulate the large-scale linear PDN system with variable stepsizes. In contrast, current conventional PDN simulation solvers have to use fixed step-size approach in order to reuse factorized matrices generated by the expensive matrix decomposition. Based on the proposed exponential integration framework, we design a PDN solver R-MATEX with the flexible time-stepping capability. The key operation of matrix exponential and vector product (MEVP) is computed by the rational Krylov subspace method. To further improve the runtime, we also propose a distributed computing framework DR-MATEX. DR-MATEX reduces Krylov subspace generations caused by frequent breakpoints from a large number of current sources during simulation. By virtue of the superposition property of linear system and scaling invariance property of Krylov subspace, DR-MATEX can divide the whole simulation task into subtasks based on the alignments of breakpoints among those sources. The subtasks are processed in parallel at different computing nodes without any communication during the computation of transient simulation. The final result is obtained by summing up the partial results among all the computing nodes after they finish the assigned subtasks. Therefore, our computation model belongs to the category known as Embarrassingly Parallel model. Experimental results show R-MATEX and DR-MATEX can achieve up to around 14.4X and 98.0X runtime speedups over traditional trapezoidal integration based solver with fixed timestep approach.

description: Silicene, analogous to graphene, is a one-atom-thick two-dimensional crystal of silicon which is expected to share many of the remarkable properties of graphene. The buckled honeycomb structure of silicene, along with its enhanced spin-orbit coupling, endows silicene with considerable advantages over graphene in that the spin-split states in silicene are tunable with external fields. Although the low-energy Dirac cone states lie at the heart of all novel quantum phenomena in a pristine sheet of silicene, the question of whether or not these key states can survive when silicene is grown or supported on a substrate remains hotly debated. Here we report our direct observation of Dirac cones in monolayer silicene grown on a Ag(111) substrate. By performing angle-resolved photoemission measurements on silicene(3x3)/Ag(111), we reveal the presence of six pairs of Dirac cones on the edges of the first Brillouin zone of Ag(111), other than expected six Dirac cones at the K points of the primary silicene(1x1) Brillouin zone. Our result shows clearly that the unusual Dirac cone structure originates not from the pristine silicene alone but from the combined effect of silicene(3x3) and the Ag(111) substrate. This study identifies the first case of a new type of Dirac Fermion generated through the interaction of two different constituents. Our observation of Dirac cones in silicene/Ag(111) opens a new materials platform for investigating unusual quantum phenomena and novel applications based on two-dimensional silicon systems.

Some Stochastic Properties of Memoryless Individual Sequences
Creators: name: Nobel, Andrew B.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: An individual sequence of real numbers is memoryless if no continuous Markov prediction scheme of finite order can outperform the best constant predictor under the squared loss. It is established that memoryless sequences satisfy an elementary law of large numbers, and sliding-block versions of Hoeffding’s inequality and the central limit theorem. It is further established that memoryless binary sequences have convergent sample averages of every order, and that their limiting distributions are Bernoulli. Several examples and sources of memoryless sequences are given, and it is shown how memoryless binary sequences may be constructed from aggregating methods for sequential prediction.

description: To examine the minimal clinically important difference (MCID) in the treadmill 6-minute walk test (6MWT) in women with breast cancer. A secondary analysis of cross-sectional data from 112 women who were undergoing chemotherapy or had undergone anticancer treatment was conducted. Participants completed the 6MWT on a treadmill and the European Organization for Research and Treatment of Cancer Questionnaire (EORTC-QLQ-C30) twice, eight weeks apart. Change in the physical function domain of the EORTC-QLQ-C30 was used to classify the “positive change” subgroup (≥5 points difference) and the “unchanged” subgroup (<5 points difference). This was combined with the distance difference from the 6MWTs, determining the MCID as the cut-off from the area under the receiver operating characteristic (AUROC) curve (anchor-based determination). The MCID was also determined from (1) the effect size and (2) the difference in standard error (SEM) of the results of the first and second 6MWT (distribution-based determination). The MCIDs in the during-chemotherapy group was 66.5 and 41.5 m and those in the after-treatment group to be 41.4 and 40.5 m (SEM and effect size based respectively). The MCID in the treadmill 6MWT distance could be used to interpret changes in the physical health status of women with breast cancer.IMPLICATIONS FOR REHABILITATIONThe MCID for the 6MWT on treadmill in active women with breast cancer is of approximately 54 m during chemotherapy, and 41.6 m after treatment.The MCID on treadmill 6MWT distance could be used to interpret a decline in the physical health status of women with breast cancer.The 6MWT on treadmill could be an easy, feasible, performed under controlled conditions, alternative to the 6MWT to obtain valuable information in this population.

description: The amplitude of localized quantum states in random or disordered media may exhibit long range exponential decay. We present here a theory that unveils the existence of an effective potential which finely governs the confinement of these states. In this picture, the boundaries of the localization subregions for low energy eigenfunctions correspond to the barriers of this effective potential, and the long range exponential decay characteristic of Anderson localization is explained as the consequence of multiple tunneling in the dense network of barriers created by this effective potential. Finally, we show that the Weyl's formula based on this potential turns out to be a remarkable approximation of the density of states for a large variety of one-dimensional systems, periodic or random.

description: In recent years, concerns have increased over the lack of contributor diversity in open source software (OSS), despite its status as a paragon of open collaboration. OSS is an important form of digital infrastructure and part of a career path for many developers. While there exists a growing body of literature on cisgender women's under-representation in OSS, the experiences of contributors from other marginalized groups are comparatively absent from the literature. Such is the case for trans contributors, a historically influential group in OSS. In this study, we interviewed 21 trans participants to understand and represent their experiences in the OSS literature. From their experiences, we theorize two related paradoxes of openness in OSS: the paradox of openness and display and the paradox of openness and governance. In an increasingly violent world for trans people, we draw on our theorizing to build recommendations for more inclusive and safer OSS projects for contributors.

Initialization, noise, singularities, and scale in height ridge traversal for tubular object centerline extraction

Year: 2002

description: The extraction of the centerlines of tubular objects in two and three dimensional images is a part of many clinical image analysis tasks. One common approach to tubular-object centerline extraction is based on intensity ridge traversal. In this paper, we evaluate the effects of initialization, noise, and singularities on intensity ridge traversal and present multi-scale heuristics and optimal-scale measures that minimize these effects. Monte Carlo experiments using simulated and clinical data are used to quantify how these "dynamic-scale" enhancements address clinical needs regarding speed, accuracy, and automation. In particular, we show that dynamic-scale ridge traversal is insensitive to its initial parameter settings, operates with little additional computational overhead, tracks centerlines with sub-voxel accuracy, passes branch points, and handles significant image noise. We also illustrate the capabilities of the method for medical applications involving a variety of tubular structures in clinical data from different organs, patients, and imaging modalities.

description: This meta-synthesis aimed to synthesise qualitative evidence on experiences of people with Multiple Sclerosis (MS) in receiving a diagnosis, to derive a conceptual understanding of adjustment to MS diagnosis. Five electronic databases were systematically searched to identify qualitative studies that explored views and experiences around MS diagnosis. Papers were quality-appraised using a standardised checklist. Data synthesis was guided by principles of meta-ethnography, a well-established interpretive method for synthesising qualitative evidence. Thirty-seven papers were selected (with 874 people with MS). Synthesis demonstrated that around the point of MS diagnosis people experienced considerable emotional upheaval (e.g., shock, denial, anger, fear) and difficulties (e.g., lengthy diagnosis process) that limited their ability to make sense of their diagnosis, leading to adjustment difficulties. However, support resources (e.g., support from clinicians) and adaptive coping strategies (e.g., acceptance) facilitated the adjustment process. Additionally, several unmet emotional and informational support needs (e.g., need for personalised information and tailored emotional support) were identified that, if addressed, could improve adjustment to diagnosis. Our synthesis highlights the need for providing person-centred support and advice at the time of diagnosis and presents a conceptual map of adjustment for designing interventions to improve adjustment following MS diagnosis.Implications for RehabilitationThe period surrounding Multiple Sclerosis diagnosis can be stressful and psychologically demanding.Challenges and disruptions at diagnosis can threaten sense of self, resulting in negative emotions.Adaptive coping skills and support resources could contribute to better adjustment following diagnosis.Support interventions should be tailored to the needs of newly diagnosed people.

description: We describe a physics simulation software framework, MAGE, that is based on the GEANT4 simulation toolkit. MAGE is used to simulate the response of ultra-low radioactive background radiation detectors to ionizing radiation, specifically the MAJORANA and GERDA neutrinoless double-beta decay experiments. MAJORANA and GERDA use high-purity germanium detectors to search for the neutrinoless double-beta decay of 76Ge, and MAGE is jointly developed between these two collaborations. The MAGE framework contains the geometry models of common objects, prototypes, test stands, and the actual experiments. It also implements customized event generators, GEANT4 physics lists, and output formats. All of these features are available as class libraries that are typically compiled into a single executable. The user selects the particular experimental setup implementation at run-time via macros. The combination of all these common classes into one framework reduces duplication of efforts, eases comparison between simulated data and experiment, and simplifies the addition of new detectors to be simulated. This paper focuses on the software framework, custom event generators, and physics lists.

description: A family of continuous piecewise linear finite elements for thin plate problems is presented. We use standard linear interpolation of the deflection field to reconstruct a discontinuous piecewise quadratic deflection field. This allows us to use discontinuous Galerkin methods for the Kirchhoff-Love plate equation. Three example reconstructions of quadratic functions from linear interpolation triangles are presented: a reconstruction using Morley basis functions, a fully quadratic reconstruction, and a more general least squares approach to a fully quadratic reconstruction. The Morley reconstruction is shown to be equivalent to the Basic Plate Triangle. Given a condition on the reconstruction operator, a priori error estimates are proved in energy norm and $L^2$ norm. Numerical results indicate that the Morley reconstruction/Basic Plate Triangle does not converge on unstructured meshes while the fully quadratic reconstruction show optimal convergence.

description: Funded by $1.2M in grants and donations, we are now building PROMPT at CTIO. When completed in late 2005, PROMPT will consist of six 0.41-meter diameter Ritchey-Chretien telescopes on rapidly slewing mounts that respond to GRB alerts within seconds, when the afterglow is potentially extremely bright. Each mirror and camera coating is being optimized for a different wavelength range and function, including a NIR imager, two red-optimized imagers, a blue-optimized imager, an UV-optimized imager, and an optical polarimeter. PROMPT will be able to identify high-redshift events by dropout and distinguish these events from the similar signatures of extinction. In this way, PROMPT will act as a distance-finder scope for spectroscopic follow up on the larger 4.1-meter diameter SOAR telescope, which is also located at CTIO. When not chasing GRBs, PROMPT serves broader educational objectives across the state of North Carolina. Enclosure construction and the first two telescopes are now complete and functioning: PROMPT observed Swift’s first GRB in December 2004. We upgrade from two to four telescope in February 2005 and from four to six telescopes in mid-2005.

description: Hypergraph partitioning lies at the heart of a number of problems in machine learning and network sciences. Many algorithms for hypergraph partitioning have been proposed that extend standard approaches for graph partitioning to the case of hypergraphs. However, theoretical aspects of such methods have seldom received attention in the literature as compared to the extensive studies on the guarantees of graph partitioning. For instance, consistency results of spectral graph partitioning under the stochastic block model are well known. In this paper, we present a planted partition model for sparse random non-uniform hypergraphs that generalizes the stochastic block model. We derive an error bound for a spectral hypergraph partitioning algorithm under this model using matrix concentration inequalities. To the best of our knowledge, this is the first consistency result related to partitioning non-uniform hypergraphs.

description: We describe a novel continuous medial representation for object geometry and a deformable templates method for  tting the representation to images. Our representation simultaneously describes the boundary and medial loci of geometrical objects, always maintaining Blum's symmetric axis transform (SAT) relationship. Cubic b-splines de ne the continuous medial locus and the associated thickness  eld, which in turn generate the object boundary. We present geometrical properties of the representation and derive a set of constraints on the b-spline parameters. The 2D representation encompasses branching medial loci; the 3D version can model objects with a single medial surface, and the extension to branching medial surfaces is a subject of ongoing research. We present preliminary results of segmenting 2D and 3D medical images. The representation is ultimately intended for use in statistical shape analysis.

description: Studying humor in the rehabilitation professions is important given its positive effects on health and well-being. We conducted a scoping review to understand how the use of humor has been explored in the existing literature in four rehabilitation professions. The rehabilitation professions included audiology, speech-language pathology, physical therapy, and occupational therapy. The five-stage method identified by Arksey and O’Malley was used to conduct this review. Six databases were searched. We included 57 articles in our final review, summarized in a narrative synthesis. We generated seven themes in our analysis: (1) humour as a management strategy in therapy; (2) humour as a power establisher vs. equalizer; (3) humour as a coping mechanism in rehabilitation; (4) conceptualizations of non-verbal humor cues in therapy; (5) Is humour trainable? (6) Humor used to foster group cohesion; and (7) Attitudes and beliefs surrounding humor practice. Our findings emphasize the importance of using humor in the rehabilitation professions, and the ways in which humor is conceptualized in a multitude of ways for both clinician and client. Future work is needed to further understand the presence and use of humor in rehabilitation professions.IMPLICATIONS FOR REHABILITATIONIn a scoping review of the literature, this study showed that humor was used mainly positively in rehabilitation by the included professions of audiology, speech-language pathology, physical therapy, and occupational therapy and contributed to a sense of belonging.Humor may be an effective way to improve management of client/clinician relations as well as improving group cohesion in rehabilitation settings.In the rehabilitation professions of audiology, speech-language pathology, physical therapy, and occupational therapy, non-verbal humor cues were used in instances where communication was difficult or impaired for clients.

description: Active systems, from bacterial suspensions to cellular monolayers, are continuously driven out of equilibrium by local injection of energy from their constituent elements and exhibit turbulent-like and chaotic patterns. Here we demonstrate both theoretically and through numerical simulations, that the crossover between wet active systems, whose behaviour is dominated by hydrodynamics, and dry active matter where any flow is screened, can be achieved by using friction as a control parameter. Moreover we discover unexpected vortex ordering at this wet-dry crossover. We show that the self organisation of vortices into lattices is accompanied by the spatial ordering of topological defects leading to active crystal-like structures. The emergence of vortex lattices, which leads to the positional ordering of topological defects, suggests potential applications in the design and control of active materials.

description: To explore, in a European cohort of people living with Parkinson’s (PD), issues affecting employment and economic consequences, considering age at diagnosis. A cross-sectional survey (European convenience sample). Inclusion criteria were ≥18 years, a PD diagnosis and in work when diagnosed. Data were collected online on demographics, employment status, occupation, and perceived health. For those no longer in paid work, time from diagnosis until loss of employment, reasons for leaving and enablers to stay in work were ascertained. Between April and November 2019, n = 692 enrolled and n = 560 were eligible. Those who had lost paid work (n = 190, 34%) reported worse fatigue, sleep, and general health than those still in work (p < 0.05). Average annual income reduced from €26973.48 ± 12013.22 (year-1) to €14843.85 ± 16969.84 (year-10). Post-diagnosis lost employment potential was 20.1 (95% confidence interval (CI): 16.6–23.6) years at career establishment, 9.8 (95%CI: 8.9–10.7) years at mid working and 1.2 (95%CI: 0.6–1.6) years for those nearing retirement age. A greater proportion of individuals at career establishment age reported dexterity, eating, sleep, fatigue, and anxiety as factors for leaving work (p < 0.05). This study confirms lost productivity after a PD diagnosis, especially in those with many years of potential employment ahead. The study also identified potential targets for interventions.

description: This paper develops a methodology for Þnding which features in a noisy image are strong enough to be distinguished from background noise. It is based on scale space, i.e. a family of smooths of the image. Pixel locations having statistically signiÞcant gradient and/or curvature are highlighted by colored symbols. The gradient version is enhanced by displaying regions of significance with streamlines. The usefulness of the new methodology is illustrated by the analysis of simulated and real images.

description: In this paper, we analyse the Wheeler-DeWitt equation in the third quantized formalism. We will demonstrate that for certain operator ordering, the early stages of the universe are dominated by quantum fluctuations, and the universe becomes classical at later stages during the cosmic expansion. This is physically expected, if the universe is formed from quantum fluctuations in the third quantized formalism. So, we will argue that this physical requirement can be used to constrain the form of the operator ordering chosen. We will explicitly demonstrate this to be the case for two different cosmological models.

description: The high quality light curves of Kepler space telescope make it possible to analyze the optical variability of AGNs with an unprecedented time resolution. Studying the asymmetry in variations could give independent constraints on the physical models for AGN variability. In this paper, we use Kepler observations of 19 sources to perform analyses on the variability asymmetry of AGNs. We apply smoothing-correction to light curves to deduct the bias to high frequency variability asymmetry, caused by long term variations which are poorly sampled due to the limited length of light curves. A parameter $β$ based on structure functions is introduced to quantitively describe the asymmetry and its uncertainty is measured using extensive Monte-Carlo simulations. Individual sources show no evidence of asymmetry at timescales of $1\sim20$ days and there is not a general trend toward positive or negative asymmetry over the whole sample. Stacking data of all 19 AGNs, we derive averaged $\barβ$ of 0.00$\pm$0.03 and -0.02$\pm$0.04 over timescales of 1$\sim$5 days and 5$\sim$20 days, respectively, statistically consistent with zero. Quasars and Seyfert galaxies show similar asymmetry parameters. Our results indicate that short term optical variations in AGNs are highly symmetric.

description: Children with cerebral palsy have altered muscle tone which makes it more difficult for them to develop, move and play like typically developing children. In children with the dyskinetic type of cerebral palsy, their bodies move in an uncontrollable way making their posture and movement appear twisting or jerky in nature. Children with this type of cerebral palsy frequently experience pain that can affect their well-being, ability to complete daily tasks, and quality of life. This thesis builds more knowledge of the pain presentations and experiences of this complex population of children to help advance practice in this area.
Supersymmetric Chern-Simons Theory in Presence of a Boundary in the Light-Like Direction

description: In this paper, we will analyze a three dimensional supersymmetric Chern-Simons theory on a manifold with a boundary. The boundary we will consider in this paper will be defined by $n\cdot x=0$, where $n$ is a light-like vector. It will be demonstrated that this boundary is preserved under the action of the $SIM(1)$ subgroup of the Lorentz group. Furthermore, the presence of this boundary will break half of the supersymmetry of the original theory. As the original Chern-Simons theory had $\mathcal{N} =1$ supersymmetry in absence of a boundary, it will only have $\mathcal{N}=1/2$ supersymmetry in presence of this boundary. We will also observe that the Chern-Simons theory can be made gauge invariant by introducing new degrees of freedom on the boundary. The gauge transformation of these new degrees of freedom will exactly cancel the boundary term obtained from the gauge transformation of the Chern-Simons theory.
