description: Recently, Lemoult et al. [Phys. Rev. Lett. 107, 064301 (2011)] used time reversal to focus sound above an array of soda cans into a spot much smaller than the acoustic wavelength in air. In this study, we show that equally sharp focusing can be achieved without time reversal, by arranging transducers around a nearly circular array of soda cans. The size of the focal spot at the center of the array is made progressively smaller as the frequency approaches the Helmholtz resonance frequency of a can from below, and, near the resonance, becomes smaller than the size of a single can. We show that the locally resonant metamaterial formed by soda cans supports a guided wave at frequencies below the Helmholtz resonance frequency. The small focal spot results from a small wavelength of this guided wave near the resonance in combination with a near field effect making the acoustic field concentrate at the opening of a can. The focusing is achieved with propagating rather than evanescent waves. No sub-diffraction-limited focusing is observed if the diffraction limit is defined with respect to the wavelength of the guided mode in the metamaterial medium rather than the wavelength of the bulk wave in air.

description: We investigate the possibility of band structure engineering in the recently predicted 2D layered form of blue phosphorus via an electric field (E$_z$) applied perpendicular to the layer(s). Using density functional theory, we study the effect of a transverse electric field in monolayer, as well as three differently stacked bilayer structures of blue phosphorus. We find that, for E$_z > 0.2$ V/Å the direct energy gap at the $Γ$ point, which is much larger than the default indirect band gap of mono- and bilayer blue phosphorus, decreases linearly with the increasing electric field; becomes comparable to the default indirect band gap at E$_z \approx 0.45 (0.35)$ V/Å for monolayer (bilayers) and decreases further until the semiconductor to metal transition of 2D blue phosphorus takes place at E$_z\approx 0.7 (0.5)$ V/Å for monolayer (bilayers). Calculated values of the electron and hole effective masses along various high symmetry directions in the reciprocal lattice suggests that the mobility of charge carriers is also influenced by the applied electric field.

description: Silicon Photomultipliers (SiPMs) are attractive candidates for light detectors for next generation liquid xenon double-beta decay experiments, like nEXO. In this paper we discuss the requirements that the SiPMs must satisfy in order to be suitable for nEXO and similar experiments, describe the two test setups operated by the nEXO collaboration, and present the results of characterization of SiPMs from several vendors. In particular, we find that the photon detection efficiency at the peak of xenon scintillation light emission (175-178 nm) approaches the nEXO requirements for tested FBK and Hamamatsu devices. Additionally, the nEXO collaboration performed radioassay of several grams of bare FBK devices using neutron activation analysis, indicating levels of 40K, 232Th, and 238U of the order of <0.15, (6.9e10-4 - 1.3e10-2), and <0.11 mBq/kg, respectively.

description: Di Pietro and Komargodski have recently demonstrated a four-dimensional counterpart of Cardy's formula, which gives the leading high-temperature ($β\rightarrow{0}$) behavior of supersymmetric partition functions $Z^{SUSY}(β)$. Focusing on superconformal theories, we elaborate on the subleading contributions to their formula when applied to free chiral and U(1) vector multiplets. In particular, we see that the high-temperature expansion of $\ln Z^{SUSY}(β)$ terminates at order $β^0$. We also demonstrate how their formula must be modified when applied to SU($N$) toric quiver gauge theories in the planar ($N\rightarrow\infty$) limit. Our method for regularizing the one-loop determinants of chiral and vector multiplets helps to clarify the relation between the 4d $\mathcal{N} = 1$ superconformal index and its corresponding supersymmetric partition function obtained by path-integration.

description: Diese Arbeit beschäftigt sich mit der Kalibrierung und Validierung eines Wasserhaushaltsmodells zur präzisen Abbildung der Gewässertemperatur eines Fließgewässers und der Implementierung von Szenarien zur hydrothermalen Nutzung. Angesichts der zu erwartenden klimatischen Veränderungen im 21. Jahrhundert gewinnt die Vorhersagegenauigkeit numerischer Modelle zunehmend an Bedeutung. Ziel dieser Arbeit ist die Anpassung des Modells an aktuelle klimatische und hydrologische Bedingungen. Des Weiteren werden Erkenntnisse über die Fähigkeit des Modells zur Abbildung von Klimaveränderungen und das Potenzial der hydrothermalen Nutzung eines Fließgewässers als nachhaltige Umweltwärmequelle gewonnen. Die Ergebnisse bestätigen die Bedeutung regelmäßiger Kalibrierungsprozesse für verlässliche Vorhersagen. Das LARSIM-Modell kann erfolgreich Abflusswerte und Gewässertemperaturen des untersuchten Gewässers, der Lahn, abbilden. Zudem zeigt die Implementierung anthropogener Szenarien interessante Ergebnisse. Untersuchungen zur Einleitung von Kühlwasser zeigen, dass die Auswirkungen auf die Gesamtgewässertemperatur gering sind. Die hydrothermale Nutzung von Fließgewässern als Umweltwärmequelle für Wärmenetze weist ein großes Potenzial auf. Die Implementierung von Referenzzuständen, welche die prognostizierten Klimaveränderungen bis zum Jahr 2045 widerspiegeln, zeigt Übereinstimmungen mit den Prognosen des Weltklimarats.

Rethinking Language in a Tech World: Exploring Socioeconomic Status, Sleep, & Screen Time in Infant Language Development
Creators: name: Kang, Iris
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: The ability to use language for effective communication with others is a critical skill that develops from an early age. While there are many factors that impact a child’s language development during infancy and early childhood, a significant portion of research has focused on how socioeconomic status (SES) and early sleep affect later language outcomes. Furthermore, as technology use has continued to grow steadily over the years, recent research has started to explore how screen time impacts language development in young children. This study sought to explore how prenatal SES, sleep at 6 months, and screen time at 18 months impact language ability at 18 months. Secondary data analyses using data collected from The Brain and Early Experience Study at The University of North Carolina at Chapel Hill were performed. Although no significant relationships were found between the predictor variables and language, a significant relationship was found between prenatal SES and 18-month screen time. More specifically, lower prenatal SES predicted higher screen time usage at 18 months. These findings underscore the importance of further exploring how screen time may impact language development and other key areas of cognitive development in young children. Furthermore, implications are discussed for exploring how to leverage existing screen time in ways that foster rather than hinder language development.

OCD and Autism: Clinician Perspectives

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Obsessive Compulsive Disorder (OCD) and Autism Spectrum Disorder (ASD) present with similar behaviors and symptoms, complicating diagnosis and treatment. Research has found that up to 37% of autistic individuals display OCD behaviors and symptoms. However, when examining clinicians, research found low confidence rates in treating co-occurring psychiatric conditions in autistic clients. The present study aims to (1) better understand the relationship between OCD and autism in realms such as treatment barriers, symptom presentation, and treatment modifications and (2) determine the training needs for clinicians when working with autistic individuals exhibiting OCD behaviors. Eleven community clinicians were interviewed using a semi-structured, open-ended interview style. Questions related to OCD and autism discussed exposure therapy training, experience treating autistic youth with OCD symptoms, and challenges related to this treatment. Interview transcripts were analyzed using thematic analysis. Clinicians discussed topics that fell under three major concepts: treatment barriers, strategies for symptom differentiation, and treatment modifications. Results highlight varied clinician understanding of current research findings related to OCD-autism co-occurrence and many clinicians voiced their desire for more training. Findings indicate training should include information on identifying and treating OCD in autistic clients.

description: Fast radio bursts (FRBs) are newly discovered radio transient sources. Their high dispersion measures indicate an extragalactic origin. But due to the lack of observational data in other wavelengths, their progenitors still remain unclear. Here we suggest the collisions between neutron stars and asteroids/comets as a promising mechanism for FRBs. During the impact process, a hot plasma fireball will form after the material of the small body penetrates into the neutron star surface. The ionized matter inside the fireball will then expand along the magnetic field lines. Coherent radiation from the thin shell at the top of the fireball will account for the observed FRBs. Our scenario can reasonably explain the main features of FRBs, such as their durations, luminosities, and the event rate. We argue that for a single neutron star, FRBs are not likely to happen repeatedly in a forseeable time span since such impacts are of low probability. We predict that faint remnant X-ray emissions should be associated with FRBs, but it may be too faint to be detected by detectors at work.

Designing Computational tools for high dimensional data with compressible features
Creators: name: Han Bao
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: In this paper, we propose a novel approach for dependency testing based on non-standard Haar wavelet expansions. Dependency testing is an important and fundamental problem in statistics, machine learning, and other related fields, where we aim to determine whether two variables in a data set are related to each other or not. In many cases, the variables under consideration exhibit complex, nonlinear relationships that are difficult to capture using traditional polynomial and Fourier basis functions, especially in large noise settings. In such cases, wavelet basis provides a useful alternative. However, traditional wavelet basis functions suffer from certain limitations, such as poor resolution and curse of dimensionality. To overcome these limitations, we propose the use of non-standard Haar wavelet basis functions which are naturally associated with a hierarchical tree structure to allow adaptive resolution of the underlying probability density function and fast computation of the expansion coefficients. The greater adaptivity of the “sparse grid" non-standard Haar wavelet basis enables better resolution when compared to traditional Walsh functions and standard Haar wavelets, and allows its application to extremely high-dimensional datasets (with compressible features) arising from a wide range of problems in Biostatistics, machine learning, and business. Unfortunately, our preliminary numerical experiments also show that when only one of the non-standard Haar expansion coefficient is used in dependency testing (e.g., maximum coefficient test), because of the local properties of the non-standard Haar basis, the statistical power of the resulting testing strategy compares poorly with other basis choices. The main contributions of this paper are two strategies to improve the statistical power of the non-standard Haar wavelet basis based dependency test algorithms. First, we introduce the concept of “skeleton" of the non-standard Haar expansion coefficients which captures most (if not all) of the statistically important features; and second, we apply the technique of “cross validation" to further improve the statistical power of the method. In the cross validation (cross checking) technique, the original data set is randomly separated into two groups, and we learn the statistical features from the first group and validate these features using data from the second group, in order to better determine if the variables are dependent. By employing these two techniques, we established a novel approach for analyzing dependencies between variables. Numerical results are presented to demonstrate the efficiency, accuracy, and statistical power of this new approach, showing that our method has the potential to surpass traditional methods. We believe that our approach represents a significant advance in the field of dependency testing and wavelet analysis.

description: In this express, we demonstrate few-layer orthorhombic arsenene is an ideal semiconductor. Due to the layer stacking, multilayer arsenenes always behave as intrinsic direct bandgap semiconductors with gap values of around 1 eV. In addition, these bandgaps can be further tuned in its nanoribbons. Based on the so-called acoustic phonon limited approach, the carrier mobilities are predicted to approach as high as several thousand square centimeters per volt-second and simultaneously exhibit high directional anisotropy. All these make few-layer arsenene promising for device applications in semiconducting industry.

Attitudes Towards Antidepressant Medications Among Neuroscience Students

Year: 2023

description: Stigma is a common reason many individuals do not seek out and adhere to treatment for mental health concerns, such as depression. Untreated mental illness can negatively impact an individual’s function, mood, and in extreme causes can lead to suicide, thus it is imperative to find ways to reduce stigma. To date most  interventions are targeted to reduce stigma towards individuals with mental illness, while few target stigma towards treatment of mental illness. The present study expands upon previous research on the utility of education in destigmatizing antidepressants. 257 undergraduate students enrolled in Introduction to Neuroscience completed a retrospective pre-post questionnaire to assess knowledge and level of stigma towards antidepressants. Wilcoxon signed-rank tests showed that from the beginning to the end of the course, students were significantly less likely to believe that antidepressants are addictive substances (p < 0.05), unnatural for the body and mind (p < 0.05), more bad than good (p < 0.05), and prescribed too frequently (p < 0.05). An additional exploratory analysis using a mixed model ANOVA was performed  to examine differences between students interested in pursuing a healthcare career relative to students uninterested in healthcare. From beginning to the end of the course content, including topics such as mental illness, serotonin systems, and reuptake inhibition, students showed significant reduction of stigma. This suggests that education of the neurobiological basis of mental illness should be considered for future education-based interventions to minimize stigma towards medicative treatments of mental illness.

description: Interfacial ferroelectricity, prevalent in various parallel-stacked layered materials, allows switching of out-of-plane ferroelectric order by in-plane sliding of adjacent layers. Its resilience against doping potentially enables next-generation storage and logic devices. However, studies have been limited to indirect sensing or visualization of ferroelectricity. For transition metal dichalcogenides, there is little knowledge about the influence of ferroelectric order on their intrinsic valley and excitonic properties. Here, we report direct probing of ferroelectricity in few-layer 3R-MoS$_2$ using reflectance contrast spectroscopy. Contrary to a simple electrostatic perception, layer-hybridized excitons with out-of-plane electric dipole moment remain decoupled from ferroelectric ordering, while intralayer excitons with in-plane dipole orientation are sensitive to it. Ab initio calculations identify stacking-specific interlayer hybridization leading to this asymmetric response. Exploiting this sensitivity, we demonstrate optical readout and control of multi-state polarization with hysteretic switching in a field-effect device. Time-resolved Kerr ellipticity reveals a direct correspondence between spin-valley dynamics and stacking order.
The relative and absolute ages of old globular clusters in the LCDM framework

description: Old Globular Clusters (GCs) in the Milky Way have ages of about 13 Gyr, placing their formation time in the reionization epoch. We propose a novel scenario for the formation of these systems based on the merger of two or more atomic cooling halos at high-redshift (z>6). First generation stars are formed as an intense burst in the center of a minihalo that grows above the threshold for hydrogen cooling (halo mass M_h~10^8 Msun) by undergoing a major merger within its cooling timescale (~150 Myr). Subsequent minor mergers and sustained gas infall bring new supply of pristine gas at the halo center, creating conditions that can trigger new episodes of star formation. The dark-matter halo around the GC is then stripped during assembly of the host galaxy halo. Minihalo merging is efficient only in a short redshift window, set by the LCDM parameters, allowing us to make a strong prediction on the age distribution for old GCs. From cosmological simulations we derive an average merging redshift =9 and narrow distribution Dz=2, implying average GC age =13.0+/-0.2 Gyr including ~0.2 Gyr of star formation delay. Qualitatively, our scenario reproduces other general old GC properties (characteristic masses and number of objects, metallicity versus galactocentric radius anticorrelation, radial distribution), but unlike age, these generally depend on details of baryonic physics. In addition to improved age measurements, direct validation of the model at z~10 may be within reach of ultradeep gravitationally lensed observations with the James Webb Space Telescope.

description: Although advances in intensive care have enabled more patients to survive an acute critical illness, they also have created a large and growing population of chronically critically ill patients with prolonged dependence on mechanical ventilation and other intensive care therapies. Chronic critical illness is a devastating condition: mortality exceeds that for most malignancies, and functional dependence persists for most survivors. Costs of treating the chronically critically ill in the United States already exceed $20 billion and are increasing. In this article, we describe the constellation of clinical features that characterize chronic critical illness. We discuss the outcomes of this condition including ventilator liberation, mortality, and physical and cognitive function, noting that comparisons among cohorts are complicated by variation in defining criteria and care settings. We also address burdens for families of the chronically critically ill and the difficulties they face in decision-making about continuation of intensive therapies. Epidemiology and resource utilization issues are reviewed to highlight the impact of chronic critical illness on our health care system. Finally, we summarize the best available evidence for managing chronic critical illness, including ventilator weaning, nutritional support, rehabilitation, and palliative care, and emphasize the importance of efforts to prevent the transition from acute to chronic critical illness. As steps forward for the field, we suggest a specific definition of chronic critical illness, advocate for the creation of a research network encompassing a broad range of venues for care, and highlight areas for future study of the comparative effectiveness of different treatment venues and approaches.

description: The microscopic mechanism of itinerant ferromagnetism is a long-standing problem due to the lack of non-perturbative methods to handle strong magnetic fluctuations of itinerant electrons. We have non-pertubatively studied thermodynamic properties and magnetic phase transitions of a two-dimensional multi-orbital Hubbard model exhibiting ferromagnetic ground states. Quantum Monte-Carlo simulations are employed, which are proved in a wide density region free of the sign problem usually suffered by simulations for fermions. Both Hund's coupling and electron itinerancy are essential for establishing the ferromagnetic coherence. No local magnetic moments exist in the system as a priori, nevertheless, the spin channel remains incoherent showing the Curie-Weiss type spin magnetic susceptibility down to very low temperatures at which the charge channel is already coherent exhibiting a weakly temperature-dependent compressibility. For the SU(2) invariant systems, the spin susceptibility further grows exponentially as approaching zero temperature in two dimensions. In the paramagnetic phase close to the Curie temperature, the momentum space Fermi distributions exhibit strong resemblance to those in the fully polarized state. The long-range ferromagnetic ordering appears when the symmetry is reduced to the Ising class, and the Curie temperature is accurately determined. These simulations provide helpful guidance to searching for novel ferromagnetic materials in both strongly correlated $d$-orbital transition metal oxide layers and the $p$-orbital ultra-cold atom optical lattice systems.

name: Kiktenko, Evgeny
Publisher: name: arXiv
Year: 2014
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this work, we consider an upper bound for the quantum mutual information in thermal states of a bipartite quantum system. This bound is related with the interaction energy and logarithm of the partition function of the system. We demonstrate the connection between this upper bound and the value of the mutual information for the bipartite system realized by two spin-1/2 particles in the external magnetic field with the XY-Heisenberg interaction.

description: Rationale: Neutrophils are usually the first circulating leukocytes to respond during bacterial pneumonia. Their expression of oxidants, proteases, and other mediators present in granules is well documented, but their ability to produce mediators through transcription and translation after migration to an inflammatory site has been appreciated only more recently. Interferon (IFN)-γ is a cytokine with many functions important in host defense and immunity.

Investigations into Alcohol Functionalization via Barton-McCombie Type Deoxygenation
Creators: name: Chufan Andrew Jin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Reactive species that are employed as electrophiles in functionalization of substrates are typically prepared from native functionality such as alcohols and carboxylic acids. The addition of a pre-functionalization step of native substrates can reduce the efficiency of syntheses. These pre-functionalization reactions along with the functionalization reactions themselves proceed through polar mechanisms, limiting the scope of both functionalization and pre-functionalization reactions. Reported herein are preliminary efforts in the development of a deoxy-functionalization protocol for secondary and tertiary alcohols. The reported protocol proceeds through a derived Barton-McCombie deoxygenation mediated by a super silyl radical. Transfer of a thiocarbonate activating group to the silyl radical generates carbon radical which can be trapped out with an external sulfonyl trap, generating sulfonyl radical, which may then react with an allylic silane allowing for turnover of the radical chain.
title: Novel Architectures for Offloading and Accelerating Computations in Artificial Intelligence and Big Data
Creators: name: Weber, Lukas Max
Publisher: name: UNSPECIFIED
Year: 2023

description: Due to the end of Moore's Law and Dennard Scaling, performance gains in general-purpose architectures have significantly slowed in recent years. While raising the number of cores has been a viable approach for further performance increases, Amdahl's Law and its implications on parallelization also limit further performance gains. Consequently, research has shifted towards different approaches, including domain-specific custom architectures tailored to specific workloads. This has led to a new golden age for computer architecture, as noted in the Turing Award Lecture by Hennessy and Patterson, which has spawned several new architectures and architectural advances specifically targeted at highly current workloads, including Machine Learning. This thesis introduces a hierarchy of architectural improvements ranging from minor incremental changes, such as High-Bandwidth Memory, to more complex architectural extensions that offload workloads from the general-purpose CPU towards more specialized accelerators. Finally, we introduce novel architectural paradigms, namely Near-Data or In-Network Processing, as the most complex architectural improvements. This cumulative dissertation then investigates several architectural improvements to accelerate Sum-Product Networks, a novel Machine Learning approach from the class of Probabilistic Graphical Models. Furthermore, we use these improvements as case studies to discuss the impact of novel architectures, showing that minor and major architectural changes can significantly increase performance in Machine Learning applications. In addition, this thesis presents recent works on Near-Data Processing, which introduces Smart Storage Devices as a novel architectural paradigm that is especially interesting in the context of Big Data. We discuss how Near-Data Processing can be applied to improve performance in different database settings by offloading database operations to smart storage devices. Offloading data-reductive operations, such as selections, reduces the amount of data transferred, thus improving performance and alleviating bandwidth-related bottlenecks. Using Near-Data Processing as a use-case, we also discuss how Machine Learning approaches, like Sum-Product Networks, can improve novel architectures. Specifically, we introduce an approach for offloading Cardinality Estimation using Sum-Product Networks that could enable more intelligent decision-making in smart storage devices. Overall, we show that Machine Learning can benefit from developing novel architectures while also showing that Machine Learning can be applied to improve the applications of novel architectures.

Exploration of the therapeutic alliance-outcome relationship: Secondary analysis of the Integrated Coping Awareness Therapy (I-CAT) randomized controlled trial
Creators: name: Bullard, Katherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: The therapeutic alliance (TA) has been an important target for psychotherapy research due to its association with successful treatment outcomes. ​​The few studies that have examined the role of the alliance-outcome relationship in first episode psychosis (FEP) have done so in the context of a limited range of treatments such as CBT, supportive counseling, and medication management. The current study examines the relationship between client and therapist-rated alliance scores within the FEP treatment delivery of Integrated-Coping Awareness Therapy (I-CAT), a manualized intervention integrating mindfulness and positive psychology to target a dysregulated stress response in schizophrenia spectrum disorders (SSD). This study is a secondary data analysis of 38 participants with FEP randomized to either the manualized I-CAT intervention (n = 19) or treatment as usual (TAU; n = 19). We hypothesized that (1) the client-rated TA scores can predict a change over time in symptom severity, perceived stress, and overall quality of life, (2) the strength of the alliance-outcome relationship differs between individuals receiving I-CAT or TAU, and (3) these relationships differ when the alliance is rated from the perspective of the therapist. We found that a better client-rated alliance was negatively associated with changes in perceived stress scores at post-treatment (β = -0.32, p = 0.004). We did not find any statistically significant associations between client-rated or therapist-rated TA scores and the other treatment outcomes. Overall, this study provides insight on the client and therapist rated alliance within the FEP treatment delivery of I-CAT.
