Cognitive Disorganization Influences Working Memory in Adolescents
Creators: name: Bleggi, Rachel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The neural diathesis-stress model of schizophrenia states that stress and cortisol production in combination with a preexisting vulnerability can lead to prodromal symptoms of the disorder. One of these prodromal symptoms, Cognitive Disorganization (CD), is a measurable attribute that often accompanies a wide range of neuropsychiatric disorders; CD may be associated with deficits in executive functions including working memory (WM), and reflect aberrant prefrontal functioning. Via EEG and neurocognitive testing, the current study examines the cognitive and neurophysiological response to stress in 127 adolescents (ages 9 to 16) who show varying risk for developing a mental disorder based on their current cognitive, affective, and familial history.

description: Pesticides are integral to modern agriculture and public health, serving as powerful tools to protect crops from pests, diseases, and invasive species. Their application has revolutionized food production, enabling farmers to increase yields and feed a growing global population. Additionally, pesticides are used in vector control programs to combat diseases like malaria, dengue, and Zika, thereby safeguarding human and animal health. However, the benefits of pesticides are accompanied by significant risks. Scientific studies have shown that many pesticides, such as organophosphates and neonicotinoids, can have deleterious effects on non-target species, including pollinators, aquatic organisms, and even humans. Pesticide residues in food, water, and soil can lead to bioaccumulation and biomagnification, posing long-term health risks such as endocrine disruption, reproductive toxicity, and carcinogenicity.  For instance, the herbicide glyphosate has been linked to cancer in humans, while neonicotinoids have been implicated in the decline of bee populations. These side effects underscore the need for thorough toxicological evaluations to ensure that the benefits of pesticide use outweigh the potential harms.

description: This paper studies the problem of option replication in general stochastic volatility markets with transaction costs, using a new specification for the volatility adjustment in Leland's algorithm \cite{Leland}. We prove several limit theorems for the normalized replication error of Leland's strategy, as well as that of the strategy suggested by Lépinette. The asymptotic results obtained not only generalize the existing results, but also enable us to fix the under-hedging property pointed out by Kabanov and Safarian. We also discuss possible methods to improve the convergence rate and to reduce the option price inclusive of transaction costs.

description: Studies of quasinormal modes (QNMs) of black holes have a long and well established history. Predominantly, much research in this area has customarily focused on the equations given by Regge, Wheeler and Zerilli. In this work we study linearized perturbations of a Schwarzschild black hole using the Characteristic formulation of numerical relativity, with an emphasis on the computation of QNMs. Within this formalism, the master equation describing gravitational perturbations is known to satisfy a fourth order differential equation. We analyse the singular points of this master equation, and obtain series solutions whose coefficients are given by three term recurrence relations, from which Leaver's continued fraction method can be applied. Using this technique, we recover the standard Schwarzschild quasinormal modes. In addition, we find that imposing purely outgoing boundary conditions, a natural feature of the Bondi-Sachs framework, leads to the recovery of the algebraically special mode.

description: We investigate the quantum phase transition in an $S = 1/2$ dimerized Heisenberg antiferromagnet in three spatial dimensions. By performing large-scale quantum Monte Carlo simulations and detailed finite-size scaling analyses, we obtain high-precision results for the quantum critical properties at the transition from the magnetically disordered dimer-singlet phase to the antiferromagnetically ordered Néel phase. This transition breaks O($N$) symmetry with $N = 3$ in $D = 3 + 1$ dimensions. This is the upper critical dimension, where multiplicative logarithmic corrections to the leading mean-field critical properties are expected; we extract these corrections, establishing their precise forms for both the zero-temperature staggered magnetization, $m_s$, and the Néel temperature, $T_N$. We present a scaling Ansatz for $T_N$, including logarithmic corrections, which agrees with our data and indicates exact linearity with $m_s$, implying a complete decoupling of quantum and thermal fluctuation effects even arbitrarily close to the quantum critical point. We also demonstrate the predicted $N$-independent leading and subleading logarithmic corrections in the size-dependence of the staggered magnetic susceptibility. These logarithmic scaling forms have not previously been identified or verified by unbiased numerical methods and we discuss their relevance to experimental studies of dimerized quantum antiferromagnets such as TlCuCl$_3$.

description: The methods for realizing of non-Abelian gauge potentials have been proposed in many different systems in condensed matter1-5. The simplest realization among them may be in a graphene bilayer obtained by slightly relative rotation between the two layers4. Here we report the experimental evidence for non-Abelian gauge potentials in twisted graphene bilayers by scanning tunnelling microscopy and spectroscopy. At a magic twisted angle, theta ~ (1.11+/-0.05)deg, a pronounced sharp peak, which arises from the nondispersive flat bands at the charge neutrality point, are observed in the tunnelling density of states due to the action of the non-Abelian gauge fields4,6-8. Moreover, we observe confined electronic states in the twisted bilayer, as manifested by regularly spaced tunnelling peaks with energy spacing detal E ~ vF/D ~ 70 meV (here vF is the Fermi velocity of graphene and D is the period of the Moire patterns). Our results direct demonstrate that the non-Abelian gauge potentials in twisted graphene bilayers confine low-energy electrons into a triangular array of quantum dots following the modulation of the Moire patterns.

HOW POLITICAL NEWS MOVES MARKETS

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The United States’ position on trade and the Federal Open Market Committee's outlook both govern the pricing of equities, debt, and other derivatives domestically and internationally. Unprecedented executive influence on trade and the Fed, coupled with a president’s unpredictable and instantaneous communication on Twitter, inspired banks and trading firms to create indexes, bots, and derivatives to account for this phenomenon. This thesis asks the question: how do President Donald Trump's tweets affect the broader stock market in terms of pricing and volatility? I use intra-day event study analysis on a sample of 2148 President Donald Trump tweets to evaluate the market impact of general tweets. I segmented the tweets into Fed-related tweets, Trade-related tweets, and other tweets before evaluating the pricing and volatility impacts using the SPX index and VIX index respectively. I found significant differences between the market reaction to trade-related tweets and Fed-related tweets and other tweets.

description: We initiate a formal study of logical inferences in context of the measure problem in cosmology or what we call cosmic logic. We describe a simple computational model of cosmic logic suitable for analysis of, for example, discretized cosmological systems. The construction is based on a particular model of computation, developed by Alan Turing, with cosmic observers (CO), cosmic measures (CM) and cosmic symmetries (CS) described by Turing machines. CO machines always start with a blank tape and CM machines take CO's Turing number (also known as description number or G{\" o}del number) as input and output the corresponding probability. Similarly, CS machines take CO's Turing number as input, but output either one if the CO machines are in the same equivalence class or zero otherwise. We argue that CS machines are more fundamental than CM machines and, thus, should be used as building blocks in constructing CM machines. We prove the non-computability of a CS machine which discriminates between two classes of CO machines: mortal that halts in finite time and immortal that runs forever. In context of eternal inflation this result implies that it is impossible to construct CM machines to compute probabilities on the set of all CO machines using cut-off prescriptions. The cut-off measures can still be used if the set is reduced to include only machines which halt after a finite and predetermined number of steps.

Velocity-Enhanced Decoherence: A Criterion for the Quantum-to-Classical Transition with Proton Energy Calculations
Creators: name: arrabal, humberto
Publisher: name: Zenodo
Year: 2024

description: This thesis explores the role of velocity in the quantum-to-classical transition, focusing on how increased particle velocity accelerates quantum decoherence. While traditional models emphasize environmental factors like temperature and pressure, they overlook the influence of velocity on the loss of quantum coherence. This research proposes a velocity-dependent criterion for decoherence, derived from the relationship between particle velocity and de Broglie wavelength. Proton systems are used as a model to calculate critical velocities at which quantum coherence vanishes, supported by both theoretical and experimental data.The study incorporates relativistic corrections to assess the effect of high velocities on decoherence and calculates the critical velocity for protons, which is approximately 1.34 × 10⁶ m/s. Additionally, proton energy in high-temperature systems is analyzed, showing that even sub-relativistic velocities can lead to rapid decoherence. The experimental setup involves measuring proton energy and velocity using advanced techniques such as spectroscopy and time-of-flight measurements.The findings have important implications for quantum computing, where controlling velocity could help stabilize qubits by reducing decoherence rates. Furthermore, the model offers insights into cosmological phenomena, suggesting that velocity-enhanced decoherence played a role in the early universe’s quantum-to-classical transition. Future research will extend this framework to other particles and further explore the cosmological impacts of velocity-enhanced decoherence.

description: We apply the coupled cluster method to high orders of approximation and exact diagonalizations to study the ground-state properties of the triangular-lattice spin-$s$ Heisenberg antiferromagnet. We calculate the fundamental ground-state quantities, namely, the energy $e_0$, the sublattice magnetization $M_{\rm sub}$, the in-plane spin stiffness $ρ_s$ and the in-plane magnetic susceptibility $χ$ for spin quantum numbers $s=1/2, 1, \ldots, s_{\rm max}$, where $s_{\rm max}=9/2$ for $e_0$ and $M_{\rm sub}$, $s_{\rm max}=4$ for $ρ_s$ and $s_{\rm max}=3$ for $χ$. We use the data for $s \ge 3/2$ to estimate the leading quantum corrections to the classical values of $e_0$, $M_{\rm sub}$, $ρ_s$, and $χ$. In addition, we study the magnetization process, the width of the 1/3 plateau as well as the sublattice magnetizations in the plateau state as a function of the spin quantum number $s$.

A Program Evaluation of UNC's Surgical Intensive Care Unit Palliative Care Quality Improvement Initiative
Creators: name: Paré, Kristina
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: ABSTRACT 
Objectives: Vast evidence shows the benefits of palliative care for chronically ill patients, however, palliative care is less studied for trauma and acute care surgery patients. UNC Hospital’s Surgical Intensive Care Unit (SICU) has adopted a quality improvement initiative to improve the use of palliative care for surgical patients. This study evaluated the project’s impact on patients’ palliative care experiences and awareness.
Methods: Semi-structured interviews were conducted with five families of patients in the UNC SICU. The families were asked to describe their experiences of palliative care conversations with the SICU team and their preferences of educational materials on palliative and ICU care. The interviews were manually transcribed and analyzed. 
Results: Three main themes were deduced from the interviews: communication, team performance, and family awareness. All interviewees spoke about the importance of learning style with regards to their preference of modalities for learning about palliative care. Interviewees also emphasized the importance of clear, honest communication with the providers and inclusiveness with the care team. When asked about goals of care discussions, many interviewees were not able to recall if they had had this conversation with the care team.   
Conclusions: The UNC SICU would benefit from a full-time palliative care specialist who could help clarify goals of care discussions and their importance in aligning the families’ wishes with treatment plans. Additionally, the UNC SICU team should be made aware of patient families’ value of transparency in communication and the use of layman’s terms when explaining the medical state of their loved one. The UNC SICU should incorporate a variety of palliative care, educational materials for families, including written materials for families who prefer tangible resources.

description: We investigate the spectral and timing properties of the millihertz quasi-periodic oscillations (mHz QPOs) in neutron-star low-mass X-ray binary 4U 1636-53 using XMM-Newton and Rossi X-ray Timing Explorer (RXTE) observations. The mHz QPOs in the XMM-Newton/RXTE observations show significant frequency variation and disappear right before type I X-ray bursts. We find no significant correlation between the mHz QPO frequency and the temperature of the neutron-star surface, which is different from theoretical predictions. For the first time we observed the full lifetime of a mHz QPO lasting 19 ks. Besides, we also measure a frequency drift timescale around 15 ks, we speculate that this is the cooling timescale of a layer deeper than the burning depth, possibly heated by the previous burst. Moreover, the analysis of all X-ray bursts in this source shows that all type I X-ray bursts associated with the mHz QPOs are short, bright and energetic, suggesting a potential connection between mHz QPOs and He-rich X-ray bursts.

   Γίνεται σύγκριση των κτιρίων αυτών με νεότερα κτίρια και την γενική εικόνα του οικισμού, με την βοήθεια του νομοθετικού πλαισίου προστασίας του οικισμού. Στοχεύεται η αποτίμηση της αποτελεσματικότητας της προστασίας και της διατήρησης του χαρακτήρα του οικισμού αλλά και κατά πόσο εναρμονίζονται τα νεότερα κτίσματα με τον παραδοσιακό χαρακτήρα του οικισμού και αν καταφέρνουν να συνυπάρχουν χωρίς να επισκιάζουν τα παραδοσιακά κτίρια.

description: We solved the Schrödinger problem for a two-dimensional electron gas (2DEG) with the Rashba spin-orbit interaction in the presence of a strong high-frequency electromagnetic field (dressing field). The found eigenfunctions and eigenenergies of the problem are used to describe the spin dynamics of the dressed 2DEG within the formalism of the density matrix response function. Solving the equations of spin dynamics, we show that the dressing field can switch the spin relaxation in the 2DEG between the cases corresponding to the known Elliott-Yafet and D'yakonov-Perel' regimes. As a result, the spin properties of the 2DEG can be tuned by a high-frequency electromagnetic field. The present effect opens an unexplored way for controlling the spin with light and, therefore, forms the physical prerequisites for creating light-tuned spintronics devices.

description: We investigate the influence of bulk viscosity on late-time cosmic acceleration within an extended $f(Q, L_m)$ gravity framework, where the non-metricity $Q$ is non-minimally coupled with the matter Lagrangian $L_m$. Analyzing the function $f(Q, L_m) = αQ + βL_m$, we derive exact solutions under non-relativistic matter domination. Using observational datasets ($H(z)$, Pantheon supernovae, and their combination), we constrain the model parameters $H_0$, $α$, $β$, and $ζ$. The deceleration parameter transitions from positive to negative values around redshifts $z_t \approx 0.80$ to $0.99 $, indicating current accelerated expansion. Moreover, the effective equation of state parameter, $ω_{eff}$, resembles quintessence dark energy ($-1 < ω_{eff} < -\frac{1}{3}$), with corresponding values from respective datasets. Finally, we use the $Om(z)$ diagnostic, which confirms that our model demonstrates quintessence-like behavior. Our findings underscore the significant role of bulk viscosity in understanding accelerated expansion in the universe within alternative gravity theories.

description: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the novel viral disease COVID-19. With no approved therapies, this pandemic illustrates the urgent need for broad-spectrum antiviral countermeasures against SARS-CoV-2 and future emerging CoVs. We report that remdesivir (RDV) potently inhibits SARS-CoV-2 replication in human lung cells and primary human airway epithelial cultures (EC50 = 0.01 μM). Weaker activity is observed in Vero E6 cells (EC50 = 1.65 μM) because of their low capacity to metabolize RDV. To rapidly evaluate in vivo efficacy, we engineered a chimeric SARS-CoV encoding the viral target of RDV, the RNA-dependent RNA polymerase of SARS-CoV-2. In mice infected with the chimeric virus, therapeutic RDV administration diminishes lung viral load and improves pulmonary function compared with vehicle-treated animals. These data demonstrate that RDV is potently active against SARS-CoV-2 in vitro and in vivo, supporting its further clinical testing for treatment of COVID-19.

Local structure-mobility relationships of confined fluids reverse upon supercooling

description: We examine the structural and dynamic properties of confined binary hard-sphere mixtures designed to mimic realizable colloidal thin films. Using computer simulations, governed by either Newtonian or overdamped Langevin dynamics, together with other techniques including a Fokker-Planck equation-based method, we measure the position-dependent and average diffusivities of particles along structurally isotropic and inhomogeneous dimensions of the fluids. At moderate packing fractions, local single-particle diffusivities normal to the direction of confinement are higher in regions of high total packing fraction; however, these trends are reversed as the film is supercooled at denser average packings. Auxiliary short-time measurements of particle displacements mirror data obtained for experimental supercooled colloidal systems. We find that average dynamics can be approximately predicted based on the distribution of available space for particle insertion across orders of magnitude in diffusivity regardless of the governing microscopic dynamics.
