Autism Spectrum Disorder
Internet content

description: This study uses a direct content analysis approach to evaluate chapter websites of the Autism Society among the southern United States. With the increasing prevalence of autism spectrum disorders (ASDs), having access to appropriate and correct information is vital. 37 websites across 17 states were evaluated based on standards inspired by previous research on the information needs of families and individuals affected by ASD. The results demonstrate that 4 websites provided content on an excellent level, 21 at a satisfactory level, 9 at a poor level, and 2 were unable to be evaluated. The discrepancy among websites and content for local chapters of the Autism Society suggests the need for an enforced standardization and redesign of chapter websites. This will ensure that searchers using this resource for information have an equal opportunity to resolving their information needs.

Digital preservation

description: The University of North Carolina at Chapel Hill (UNC-Chapel Hill) is exploring opportunities to support the teaching and research needs of its administrators, faculty, and students through the preservation and dissemination of its digital assets. Recent studies suggest that much of this intellectual output is at risk and may disappear unless stewards of this information emerge and take active steps to ensure its preservation for current and future use. This paper presents the results of a survey of 200 UNC faculty members that documents current processes and practices related to research materials. It serves as an important first step in a process designed to describe the needs and expectations of information producers on campus related to the collection, storage, and preservation of research materials.
On the extension of the sensitive area of an extensive air shower surface array
Creators: name: Kh, H. Hedayati
Publisher: name: arXiv
Year: 2016
Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: A large distance between true and reconstructed core locations of an extensive air shower (EAS) may results in great systematic mis-estimation of EAS parameters. The reconstruction of those EASs whose core locations are outside the boundary of a surface array (outside EAS (OEAS)) results in a large distance of the reconstructed core location from the true one, especially when the true core is far outside the array. Although it may not be mentioned, the identification of OEASs is a necessary and important step in the reconstruction procedure of an EAS. In this paper, an existing technique is optimized for the identification of OEASs. The simultaneous use of this technique and a recently developed approach for reconstructing the core location of an EAS can significantly increase the sensitive area of a surface array.

We show that under this assumption, the simultaneous transmission and creation of particles is impossible in generic interacting theories.
Elliptical graphical modelling

Publisher: name: arXiv
Year: 2015
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: We propose elliptical graphical models based on conditional uncorrelatedness as a general- ization of Gaussian graphical models by letting the population distribution be elliptical instead of normal, allowing the fitting of data with arbitrarily heavy tails. We study the class of propor- tionally affine equivariant scatter estimators and show how they can be used to perform elliptical graphical modelling, leading to a new class of partial correlation estimators and analogues of the classical deviance test. General expressions for the asymptotic variance of partial correla- tion estimators, unconstrained and under decomposable models, are given, and the asymptotic chi square approximation of the pseudo-deviance test statistic is proved. The feasibility of our approach is demonstrated by a simulation study, using, among others, Tyler's scatter estimator, which is distribution-free within the elliptical model. Our approach provides a robustification of Gaussian graphical modelling. The latter is likelihood-based and known to be very sensitive to model misspecification and outlying observations.

We prove that for $σ$d$\ge$2, they are strongly illposed in the Sobolev space H^s for any s \textless{} 0, exhibiting norm-inflation with infinite loss of regularity. In the case of the one-dimensional cubic nonlinear Schr{ö}dinger equation and its renormalized version we prove such a result for H^s with s \textless{} --2/3.

Subjects: Text mining

description: This study investigated the use of automated clustering of event descriptions as a tool for developing a keyword taxonomy for a database product. Automatically-generated cluster labels were translated into keywords and domain experts reviewed the keywords alongside corresponding event descriptions. The experts evaluated the keywords for a) relevance to the event descriptions and b) goodness or use value as keywords. The results show that the keywords performed better in terms of goodness than in terms of relevance.  In addition, data mining techniques showed that many of the keywords correlated closely with classifications already in use for the database.

Symmetry boosts quantum computer performance
Creators: name: Nam, Y. S.
name: Blümel, R.
Publisher: name: arXiv
Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Frequently, subroutines in quantum computers have the structure $\mathcal{F}\mathcal{U}\mathcal{F}^{-1}$, where $\mathcal{F}$ is some unitary transform and $\mathcal{U}$ is performing a quantum computation. In this paper we suggest that if, in analogy to spin echoes, $\mathcal{F}$ and $\mathcal{F}^{-1}$ can be implemented symmetrically such that $\mathcal{F}$ and $\mathcal{F}^{-1}$ have the same hardware errors, a symmetry boost in the fidelity of the combined $\mathcal{F}\mathcal{U}\mathcal{F}^{-1}$ quantum operation results. Running the complete gate--by--gate implemented Shor algorithm, we show that the fidelity boost can be as large as a factor 10. Corroborating and extending our numerical results, we present analytical scaling calculations that show that a symmetry boost persists in the practically interesting case of a large number of qubits. Our analytical calculations predict a minimum boost factor of about 3, valid for all qubit numbers, which includes the boost factor 10 observed in our low-qubit-number simulations. While we find and document this symmetry boost here in the case of Shor's algorithm, we suggest that other quantum algorithms might profit from similar symmetry-based performance boosts whenever $\mathcal{F}\mathcal{U}\mathcal{F}^{-1}$ sub-units of the corresponding quantum algorithm can be identified.

description: With the expanding integration of infrared instruments in astronomical missions, accurate per-pixel flux estimation for near-infrared hybrid detectors has become critical to the success of these missions. Based on CPPM's involvement in both SVOM/Colibri and Euclid missions, this study introduces universally applicable methods and framework for characterizing IR hybrid detectors and decorrelating their intrinsic properties. The characterization framework, applied to the ALFA detector and \Euclid's H2RG, not only validates the proposed methods but also points out subtle behaviors inherent to each detector.

description: The purpose of this research is to study the literature of policymaking, both for Curriculum Materials Centers and general libraries, in order to develop a framework for a UNC-CH Curriculum Materials Center (CMC) policy manual. The following policies were selected for inclusion in the CMC policy manual: philosophy and goals, collection development, budget management, media center use, scheduling, building support, and evaluation. A process for policymaking by a committee of stakeholders was developed during the process of drafting two initial policies: the philosophy and goals statement and the collection development policy. Although the CMC currently lacks a full-time licensed librarian, the policies and the process of policy development via members of the library's constituency will move the CMC towards a more established stance. Patrons will be able to hold the CMC to professional standards.
The first-digit frequencies in data of turbulent flows

Publisher: name: arXiv
Year: 2015
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: Considering the first significant digits (noted d) in data sets of dissipation for turbulent flows, the probability to find a given number (d=1 or 2 or... 9) would be 1/9 for an uniform distribution. Instead the probability closely follows Newcomb-Benford's law, namely P(d)=log(1+1/d). The discrepancies between Newcomb-Benford's law and first-digits frequencies in turbulent data are analysed through Shannon's entropy. The data sets are obtained with direct numerical simulations for two types of fluid flow: an isotropic case initialized with a Taylor-Green vortex and a channel flow. Results are in agreement with Newcomb-Benford's law in nearly homogeneous cases and the discrepancies are related to intermittent events. Thus the scale invariance for the first significant digits, which supports Newcomb-Benford's law, seems to be related to an equilibrium turbulent state, namely with a significant inertial range. A matlab/octave program is provided in appendix in such that part of the presented results can easily be replicated.
Weak convergence of the empirical process and the rescaled empirical distribution function in the Skorokhod product space

Subjects: subject: Probability (math.PR)

description: We prove the asymptotic independence of the empirical process $α_n = \sqrt{n}( F_n - F)$ and the rescaled empirical distribution function $β_n = n (F_n(τ+\frac{\cdot}{n})-F_n(τ))$, where $F$ is an arbitrary cdf, differentiable at some point $τ$, and $F_n$ the corresponding empricial cdf. This seems rather counterintuitive, since, for every $n \in N$, there is a deterministic correspondence between $α_n$ and $β_n$. Precisely, we show that the pair $(α_n,β_n)$ converges in law to a limit having independent components, namely a time-transformed Brownian bridge and a two-sided Poisson process. Since these processes have jumps, in particular if $F$ itself has jumps, the Skorokhod product space $D(R) \times D(R)$ is the adequate choice for modeling this convergence in. We develop a short convergence theory for $D(R) \times D(R)$ by establishing the classical principle, devised by Yu. V. Prokhorov, that finite-dimensional convergence and tightness imply weak convergence. Several tightness criteria are given. Finally, the convergence of the pair $(α_n,β_n)$ implies convergence of each of its components, thus, in passing, we provide a thorough proof of these known convergence results in a very general setting. In fact, the condition on $F$ to be differentiable in at least one point is only required for $β_n$ to converge and can be further weakened.

description: Based on official estimates, 50 million people worldwide are affected by dementia, and this number increases by 10 million new patients every year. Without a cure, clinical prognostication and early intervention represent the most effective ways to delay its progression. To this end, Artificial Intelligence and computational linguistics can be exploited for natural language analysis, personalized assessment, monitoring, and treatment. However, traditional approaches need more semantic knowledge management and explicability capabilities. Moreover, using Large Language Models (LLMs) for cognitive decline diagnosis is still scarce, even though these models represent the most advanced way for clinical-patient communication using intelligent systems. Consequently, we leverage an LLM using the latest Natural Language Processing (NLP) techniques in a chatbot solution to provide interpretable Machine Learning prediction of cognitive decline in real-time. Linguistic-conceptual features are exploited for appropriate natural language analysis. Through explainability, we aim to fight potential biases of the models and improve their potential to help clinical workers in their diagnosis decisions. More in detail, the proposed pipeline is composed of (i) data extraction employing NLP-based prompt engineering; (ii) stream-based data processing including feature engineering, analysis, and selection; (iii) real-time classification; and (iv) the explainability dashboard to provide visual and natural language descriptions of the prediction outcome. Classification results exceed 80 % in all evaluation metrics, with a recall value for the mental deterioration class about 85 %. To sum up, we contribute with an affordable, flexible, non-invasive, personalized diagnostic system to this work.

description: This study describes a survey and subsequent observation of the use of a medical decision support system by pediatricians at the University of North Carolina Medical Center. The study was conducted to study how system design issues such as ease of use and provision of explanations affect residents' use of the expert system. Use of the system recommendations varies by resident and patient. Residents for the most part find the decision support system useful and helpful for routine physicals, but for patient visits that are more particular in nature, residents find that they must rely on their own expertise to provide the appropriate and fitting level of treatment. The presence of multiple reporting systems also dilutes the efficacy of the decision support system. Issues of trust in the system recommendations and its explanations of those recommendations are also relevant.

description: We present the updated orbital solution for the transient Be X-ray binary V 0332+53 comple- menting historical measurements with the data from the gamma-ray burst monitor onboard Fermi obtained during the outburst in June-October 2015. We model the observed changes in the spin- frequency of the pulsar and deduce the orbital parameters of the system. We significantly improve existing constrains and show that contrary to the previous findings no change in orbital parameters is required to explain the spin evolution of the source during the outbursts in 1983, 2005 and 2015. The reconstructed intrinsic spin-up of the neutron star during the latest outburst is found to be comparable with previosly observed values and predictions of the accretion torque theory.

description: Radioactive nuclei play an important role in planetary evolution by providing an internal heat source, which affects planetary structure and helps facilitate plate tectonics. A minimum level of nuclear activity is thought to be necessary --- but not sufficient --- for planets to be habitable. Extending previous work that focused on short-lived nuclei, this paper considers the delivery of long-lived radioactive nuclei to circumstellar disks in star forming regions. Although the long-lived nuclear species are always present, their abundances can be enhanced through multiple mechanisms. Most stars form in embedded cluster environments, so that disks can be enriched directly by intercepting ejecta from supernovae within the birth clusters. In addition, molecular clouds often provide multiple episodes of star formation, so that nuclear abundances can accumulate within the cloud; subsequent generations of stars can thus receive elevated levels of radioactive nuclei through this distributed enrichment scenario. This paper calculates the distribution of additional enrichment for $^{40}$K, the most abundant of the long-lived radioactive nuclei. We find that distributed enrichment is more effective than direct enrichment. For the latter mechanism, ideal conditions lead to about 1 in 200 solar systems being directly enriched in $^{40}$K at the level inferred for the early solar nebula (thereby doubling the abundance). For distributed enrichment from adjacent clusters, about 1 in 80 solar systems are enriched at the same level. Distributed enrichment over the entire molecular cloud is more uncertain, but can be even more effective.

description: We utilize the variational method to study the Kondo screening of a spin-$1/2$ magnetic impurity in a three-dimensional (3D) Weyl semimetal with two Weyl nodes along the $k_z$-axis. The model reduces to a 3D Dirac semimetal when the separation of the two Weyl nodes vanishes. When the chemical potential lies at the nodal point, $μ=0$, the impurity spin is screened only if the coupling between the impurity and the conduction electron exceeds a critical value. For finite but small $μ$, the impurity spin is weakly bound due to the low density of state, which is proportional to $μ^2$, contrary to that in a 2D Dirac metal such as graphene and 2D helical metal where the density of states is proportional to $|μ|$. The spin-spin correlation function $J_{uv}(\mathbf{r})$ between the spin $v$-component of the magnetic impurity at the origin and the spin $u$-component of a conduction electron at spatial point $\mathbf{r}$, is found to be strongly anisotropic due to the spin-orbit coupling, and it decays in the power-law. The main difference of the Kondo screening in 3D Weyl semimetals and in Dirac semimetals is in the spin $x$- ($y$-) component of the correlation function in the spatial direction of the $z$-axis.

description: This study investigates the Structural Biology Central Facility at a large academic research institution and examines the Central Facility's most pressing data management needs.  The University's Health Affairs Library has undertaken an initiative to pursue data management support for researchers in the biomedical sciences and the central facility has been identified as one of the library's first partners in assessing and proposing data management services the library could provide.
Five groups of campus stakeholders that mutually contribute and participate in assisting the structural biology central facility were identified and interviewed to identify contributions to the central facility's data management practices.  From these interviews, seven major obstacles were identified around which the Health Affairs Library could develop novel strategies for extending data management services into biomedical research environments.

description: Data sets collected in the real world usually contain large amounts of features, many of which are interdependent with each other. The number of dimensions that can be shown concurrently with modern visualization techniques often does not match the number of features contained in the dataset, and this discrepancy can lead to selection bias undetected. This paper presents an advanced visualization system designed to enable sample bias detection introduced during the high-dimensional data selection and visualization, and to support the bias reduction using a sample-reweighting algorithm. A detailed description of the system's web-based interactive user interface is provided. In addition, the results from an 11-participant user study on the system are presented, which demonstrate the effectiveness of the system in practice.

description: A cooperative network model of sociological interest is examined to determine the sensitivity of the global dynamics to having a fraction of the members behaving uncooperatively, that is, being in conflict with the majority. We study a condition where in the absence of these uncooperative individuals, the contrarians, the control parameter exceeds a critical value and the network is frozen in a state of consensus. The network dynamics change with variations in the percentage of contrarians, resulting in a balance between the value of the control parameter and the percentage of those in conflict with the majority. We show that the transmission of information from a network $B$ to a network $A$, with a small fraction of lookout members in $A$ who adopt the behavior of $B$, becomes maximal when both networks are assigned the same critical percentage of contrarians.

A systematic study of structural, electronic and optical properties of atomic scale defects in 2D transition metal dichalcogenides MX$_2$ (M = Mo,W; X = S, Se, Te)

description: In this work, we have systematically studied structural, electronic and magnetic properties of atomic scale defects in 2D transition metal dichalcogenides MX$_2$, (M = Mo and W; X = S, Se and Te) by density functional theory. Various types of defects, e.g., X vacancy, X interstitial, M vacancy, M interstitial, MX and XX double vacancies have been considered. It has been found that the X interstitial has the lowest formation energy ($\sim$ 1 eV) for all the systems in the X--rich condition whereas for M--rich condition, X vacancy has the lowest formation energy except for \ce{MTe2} systems. Both these defects have very high equilibrium defect concentrations at growth temperatures (1000K-1200K) reported in literature. A pair of defects, e.g., two X vacancies or one M and one X vacancies tend to occupy the nearest possible distance. No trace of magnetism has been found for any one of the defects considered. Apart from X interstitial, all other defects have defect states appearing in the band gap, which can greatly affect the electronic and optical properties of the pristine systems. Our calculated optical properties show that the defect states cause optical transitions at $\sim$ 1.0 eV, which can be beneficial for light emitting devices. The results of our systematic study are expected to guide the experimental nanoengineering of defects to achieve suitable properties related to band gap modifications and characterization of defect fingerprints via optical absorption measurements.
Unintended Consequences of Climate Change Mitigation for African River Basins

description: This presentation was given during the 2022 AGU Fall Meeting in Chicago, IL. Global policies to mitigate climate change suggest the need of pricing greenhouse gas emissions to attain rapid emissions reductions. The efficacy of these measures is generally assessed at the global or regional scale, while their local impacts are often difficult to anticipate and are consequently overlooked in many analyses. This study addresses this gap by investigating how multisector dynamics across interconnected Water-Energy-Food (WEF) systems at the local scale are impacted by global climate change mitigation efforts. We use a detailed river basin scale operational model of the Zambezi Watercourse in Southern Africa that enables the exploration of synergies, tradeoffs, and vulnerabilities for the local WEF systems. Our analysis includes more than 7,000 scenarios that combine different climate and socio-economic projections with alternative mitigation policies. Future irrigation demands are generated by systematically sampling the Shared Socioeconomic Pathways components along with multiple Shared Policy Assumptions. Future water availability is instead produced by forcing local hydrological models with bias-adjusted climate projections from different combinations of global and regional climate models for different Representative Concentration Pathways. Our results contribute quantitative evidence of the unintended vulnerabilities that may emerge in the Zambezi Watercourse. Policy fragmentation between developed and developing countries in their approach to land-use change emissions can have negative side effects on local water demands, producing favorable conditions for the realization of extensive agricultural projects in Africa where the price associated to the land-use change emission is low. This generates irrigation demands two times higher than under globally coordinated approaches to emissions reductions and constrains the availability of water resources for hydropower production or the provision of ecosystem services. Analogous vulnerabilities could impact many river basins in Southern and Western Africa. It is critical to connect global climate change mitigation policies to local dynamics for a better understanding of the full range of possible future scenarios while supporting policy makers in prioritizing sustainable mitigation and adaptation solutions.

description: This paper presents a series of 95 new measurements of the longitudinal (effective) magnetic field $B_e$ of the Ap star $γ$ Equ (HD 201601). Observations were obtained at the coudé focus of the 1-m reflector at the Special Astrophysical Observatory (SAO RAS) in Russia over a time period of 4190 days (more than 11 years). We compiled a long record of $B_e$ points, adding our measurements to all published data. The time series of magnetic data consists of 395 $B_e$ points extending for 24488 days, or over 67 years. Various methods of period determination were examined for the case in which the length of the observed time series is rather short and amounts only to ~69 percent of the period. We argue that the fitting of a sine wave to the observed $B_e$ points by least squares yields the most reliable period in the case of $γ$ Equ. Therefore, the best period for long-term magnetic variations of $γ$ Equ, and hence the rotational period, is $P_{\rm rot}=35462.5 \pm 1149$ days $= 97.16 \pm 3.15$ years.
