description: This work explores the relation between magnetic islands, long range temporal correlations and heat transport. A low order rational surface ($ι/2π= 3/2$) was purposely scanned outward through an Electron Cyclotron Resonance Heated (ECRH) plasma in the TJ-II stellarator. Density turbulence and the poloidal flow velocity (or radial electric field) were characterized using a two channel Doppler Reflectometer. Simultaneously, the ECRH power was modulated to characterize heat transport, using measurements from a 12 channel Electron Cyclotron Emission diagnostic. A systematic variation of the poloidal velocity was found to be associated with the stationary $ι/2π= 3/2$ magnetic island. Inside from the rational surface, the Hurst coefficient, quantifying the nature of long-range correlations, was found to be significantly enhanced. Simultaneously, heat transport was enhanced as well, establishing a clear link between density fluctuations and anomalous heat transport. The variation of the Hurst coefficient was consistent with a magnetohydrodynamic turbulence simulation.

Sewage Impacts on Water Quality and Antibiotic Resistance in Beach Waters in the Galápagos Islands, Ecuador
Creators: name: Overbey, Katie

Year: 2014

description: Tourism and residential population growth are increasing on the Galápagos Islands, yet the effects on environmental quality are not well understood. This study provides a baseline characterization of water quality on one of the inhabited islands of the Galápagos (San Cristóbal), and evaluates the potential relationship between human activity and bacterial antibiotic resistance in recreational waters on this island. Five sample beaches and the mouths of two sewage effluent pipes were selected to represent recreational water with and without the presence of sewage effluent. Enterococci concentrations were quantified using the IDEXX Enterolert kit. Escherichia coli was isolated from samples and tested for susceptibility to five antibiotics using Kirby- Bauer disk diffusion. These measurements were compared between beaches with sewage effluent and beaches without sewage effluent. Significantly higher enterococci concentrations were found near sites subjected to sewage discharge (p < 0.01). Sites of direct sewage discharge and land drainage from the highlands had significantly higher levels of antibiotic resistant bacteria though it is unclear whether sewage impacts the level of resistance at nearby beaches (p < 0.05). The high levels of enterococci and antibiotic resistance observed in this study indicate that the release of raw sewage into recreational waters could be putting the environment as well as public health at risk. This study provides insight into how humans impact their environment in an area where economic and developmental demands compete with environmental and public health concerns.

Negotiating Identity: A Sociological Study of Chinese Adoptees in the United States
Creators: name: Yang, Yue (Ashelee)
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: In the 15 years from 1999 to 2013, a total number of 15,071,066 new immigrants gained
permanent residency in the United States. During the same period, 249,694 children have been
internationally adopted,2 which constitutes 1.66% of the overall immigrant population. Although
international adoption, simply by looking at numbers, is not the major source of immigration, it
is a phenomenon that requires special attention in the field of migration research. While migration
has always been conceptualized as the result of migrants’ voluntary decisions, in the case of
international adoption, the adoptees are usually too young to give consents (Louie, 2013). This
involuntary action is also associated with insufficient preparation for the move, as well as other
post-adoption issues including psychological development, nurturing intimate family relationship,
and incorporation into the American society.
This study focuses on international adoption between the United States and China. It
takes a close look at the adoption process, and aims to capture the unique experience of the
adopted children with an emphasis on identity formation. It explores how the adoptees identify
themselves in terms of culture, race and ethnicity. At the same time, it also tries to explain the
social mechanisms behind these identity choices, as adoptees are radicalized and culturally socialized
under the broader social arrangements of the United States.

description: The existence of inequivalent valleys K and K' in the momentum space of two-dimensional hexagonal lattices provides a new electronic degree of freedom, the manipulation of which can potentially lead to new types of electronics, in analogy to the role played by electron spin. In materials with broken inversion symmetry, such as an electrically gated bilayer graphene, the momentum-space Berry curvature $Ω$ carries opposite sign in the K and K' valleys. A sign reversal of $Ω$ along an internal boundary of the sheet gives rise to counter-propagating one-dimensional conducting modes encoded with opposite valley indices. These metallic states are topologically protected against backscattering in the absence of valley-mixing scattering, and thus can carry current ballistically. In bilayer graphene, the reversal of $Ω$ can occur at the domain wall of AB and BA stacked domains, or at the line junction of two oppositely gated regions. The latter approach can provide a scalable platform to implement valleytronic operations such as valves and waveguides, but is technically challenging to realize. Here we fabricate a dual-split-gate structure in bilayer graphene and demonstrate transport evidence of the predicted metallic states. They possess a mean free path of up to a few hundred nanometers in the absence of a magnet field. The application of perpendicular magnetic field suppresses backscattering significantly and enables a 400-nanometer-long junction to exhibit conductance close to the ballistic limit of 4 $e^2/h$ at 8 Tesla. Our experiment paves the path to the realization of gate-controlled ballistic valley transport and the development of valleytronic applications in atomically thin materials.

description: Computational protein design facilitates discovery of novel proteins with prescribed structure and functionality. Exciting designs were recently reported using novel data-driven methodologies that can be roughly divided into two categories: evolutionary-based and physics-inspired approaches. The former infer characteristic sequence features shared by sets of evolutionary-related proteins, such as conserved or coevolving positions, and recombine them to generate candidates with similar structure and function. The latter estimate key biochemical properties such as structure free energy, conformational entropy or binding affinities using machine learning surrogates, and optimize them to yield improved designs. Here, we review recent progress along both tracks, discuss their strengths and weaknesses, and highlight opportunities for synergistic approaches.
Neuroimaging-based Statistical Machine Learning Classification of Schizophrenia
Creators: name: Chen, Kevin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Schizophrenia is a chronic mental disorder that affects millions in the US and tens of millions globally. It is largely believed to be caused by structural and functional differences in the brain, but its exact cause is unknown. Due to the complicated structure of the human brain, its functional connections are often represented by networks. In this thesis, we utilize brain networks generated by functional magnetic resonance imaging (fMRI) data to develop machine learning classification models that can accurately make inferences on single subjects to predict the diagnosis of schizophrenia. We look at a number of local and global connectivity measures derived from correlation-based functional connectivity matrices to do so, using a dataset provided by the National Institute of Health Center of Biomedical Research Excellence (COBRE) and 1000 Functional Connectomes project. Preprocessing and analysis of data is done through the CONN functional connectivity toolbox and MATLAB. Using a subset of subjects and global metrics, we first conduct a preliminary group comparison to determine the existence of a significant difference between patient and control groups with respect to the selected metrics. Then, we investigate machine learning classifiers using k-nearest neighbors and support vector machine models on the full dataset using an expanded set of metrics. Using these models, we observe classification accuracy rates of up to approximately 84% on testing sets using 10-fold cross validation, with sensitivity of approximately 91% and specificity of 77% using a polynomial kernel. This rate is fairly consistent with that of other studies, which generally report classification accuracies of 60-90%. As such, the models we have developed demonstrate the potential of networks in determining the nature of schizophrenia and the uses of statistical learning in the diagnosis of neuropsychiatric disorders.

description: The nature of dark matter is unknown and calls for a systematical search. For axion dark matter, such a search relies on finding feeble random noise arising from the weak coupling between dark matter and microwave haloscopes. We model such process as a quantum channel and derive the fundamental precision limit of noise sensing. An entanglement-assisted strategy based on two-mode squeezed vacuum is thereby demonstrated optimal, while the optimality of a single-mode squeezed vacuum is found limited to the lossless case. We propose a `nulling' measurement (squeezing and photon counting) to achieve the optimal performances. In terms of the scan rate, even with 20-decibel of strength, single-mode squeezing still underperforms the vacuum limit which is achieved by photon counting on vacuum input; while the two-mode squeezed vacuum provides large and close-to-optimum advantage over the vacuum limit, thus more exotic quantum resources are no longer required. Our results highlight the necessity of entanglement assistance and microwave photon counting in dark matter search.

description: The weak-field and slow-motion limit of $f(R,\mathcal{G})$ gravity is developed up to $(v/c)^{4}$ order in a spherically symmetric background. Considering the Taylor expansion of a general function $f$ around vanishing values of $R$ and $\mathcal{G}$, we present general vacuum solutions up to $(v/c)^{4}$ order for the gravitational field generated by a ball-like source. The spatial behaviors at $(v/c)^{2}$ order are the same for $f(R,\mathcal{G})$ gravity and $f(R)$ gravity, and their corresponding real valued static behaviors are presented and compared with the one in general relativity. The static Yukawa-like behavior is proved to be compatible with the previous result of the most general fourth-order theory. At $(v/c)^{4}$ order, the static corrections to the Yukawa-like behavior for $f(R,\mathcal{G})$ gravity, $f(R)$ gravity, and the Starobinsky gravity are presented and compared with the one in general relativity.

description: By exploiting density-matrix renormalization group techniques, we investigate the dynamical spin structure factor of a spin-1/2 Heisenberg chain with ferromagnetic nearest-neighbor and antiferromagnetic next-nearest-neighbor exchange interactions in an applied magnetic field. In a field-induced spin nematic regime, we find gapless longitudinal and gapped transverse spin excitation spectra, in accordance with quasi-long-ranged longitudinal and short-ranged transverse spin correlations, respectively. The gapless point coincides with the dominant longitudinal spin correlation, whereas the gap position exhibits a characteristic field dependence contradicting the dominant transverse spin correlation.

Rare earth element behavior in springs and streams on San Cristobal Island, Galapagos
Creators: name: Larsen, William
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Dissolved Rare Earth Element (REE) fractionation mechanisms in freshwater samples have been parameterized by lab experiments and measured in major world rivers. To confirm whether results from controlled lab experiments are reciprocated in small-scale natural systems, I analyzed REE contents in water samples from groundwater springs and streams on San Cristóbal Island, Galápagos. The island is comprised of essentially a single lithological unit (Ocean Island Basalt) and exhibits a steep hydrological gradient on the windward slope over a short spatial extent which results in a wide range of physicochemical and dissolved mineralogical properties of water. This allows for the investigation of factors exerting primary control on REE fractionation without the influence of changing lithology. Samples show a wide range of pH (5.5-8.2) associated with changes from Mn-dominated dissolved fractions to Fe-dominated as pH increases. Local basalt-normalized REE patterns exhibit a wide range (La/Ybb = 0.41-1.78 and Ce/Ce*b = 0.58-2.12) for the small areal extent of the watershed (~ 13 sq. km). Comparisons between “dissolved” load (<0.45μm) and “soluble” load (<0.02μm) data demonstrate the importance of colloidal-sized metal species in aqueous solution. The difference of REE results between the "dissolved" load data are attributed to contrasting fractionation from opposing aqueous mineralogical systems (Mn vs. Fe) present across the watershed, consistent with laboratory studies.

Killing for Ireland: Escalation and De-escalation during the Troubles
Creators: name: McCarthy, Ryan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: This paper seeks to answer the question “How do groups decide between a
strategy of escalation versus de-escalation?” In order to address this question, the events
of the Troubles, a period of conflict in Northern Ireland that began in late 1969 and ended
in 1998 with the signing of the Good Friday Agreement, will be used as a case study.
The question will be addressed with the development of two game theoretic models that
will be used to analyze the behavior of the actors in the Troubles. These models will be
constructed and applied to view the conflict in terms that lend significance and possibly
support for the use of violence when considering the alternatives available to both sides.
In light of the background from which the conflict surfaced, useful information will be
gathered on why violence was ramped up rather than decreased in an effort to breed
cooperation. In order to limit the amount of incidents analyzed to one manageable by the
scope of this paper, I will focus on a twenty-year slice of the Troubles, from 1969 to
1989, encompassing roughly two-thirds of the conflict as a whole. As a theoretical tool,
game theory will shed light on the attractiveness of certain actions and outcomes over
others in situations where two or more groups are in conflict with one another.

description: Novel materials and devices in photonics have the potential to revolutionize optical information processing, beyond conventional binary-logic approaches. Laser systems offer a rich repertoire of useful dynamical behaviors, including the excitable dynamics also found in the time-resolved "spiking" of neurons. Spiking reconciles the expressiveness and efficiency of analog processing with the robustness and scalability of digital processing. We demonstrate that graphene-coupled laser systems offer a unified low-level spike optical processing paradigm that goes well beyond previously studied laser dynamics. We show that this platform can simultaneously exhibit logic-level restoration, cascadability and input-output isolation---fundamental challenges in optical information processing. We also implement low-level spike-processing tasks that are critical for higher level processing: temporal pattern detection and stable recurrent memory. We study these properties in the context of a fiber laser system, but the addition of graphene leads to a number of advantages which stem from its unique properties, including high absorption and fast carrier relaxation. These could lead to significant speed and efficiency improvements in unconventional laser processing devices, and ongoing research on graphene microfabrication promises compatibility with integrated laser platforms.

To accomplish this goal, we use a large set of appropriate operators, an anisotropic tadpole improved action, smearing techniques, and solve a generalized eigenvalue problem. Moreover, we compare our results with the Nambu-Goto string model to evaluate possible tensions which could be a signal for novel phenomena.

description: We develop a framework that facilitates the study of the causal structure of spacetimes with a causally preferred foliation. Such spacetimes may arise as solutions of Lorentz-violating theories, e.g. Horava gravity. Our framework allows us to rigorously define concepts such as black/white holes and to formalize the notion of a `universal horizon', that has been previously introduced in the simpler setting of static and spherically symmetric geometries. We also touch upon the issue of development and prove that universal horizons are Cauchy horizons when evolution depends on boundary data or asymptotic conditions. We establish a local characterisation of universal horizons in stationary configurations. Finally, under the additional assumption of axisymmetry, we examine under which conditions these horizons are cloaked by Killing horizons, which can act like usual event horizons for low-energy excitations.

description: Hollywood movies provide continuous audiovisual information. Yet, information conveyed by movies address different sensory systems. For a broad variety of media applications (such as multimedia learning environments) it is important to understand the underlying cognitive principles. This project addresses the interplay of auditory and visual information during movie perception. Because auditory information is known to change basic visual processes, it is possible that movie perception and comprehension depends on stimulus modality. In this project, we report three experiments that studied how humans perceive and remember changes in visual and audiovisual movie clips. We observed basic processes of event perception (event segmentation, change detection, and memory) to be independent of stimulus modality. We thus conclude that event boundary perception is a general perceptual-cognitive mechanism and discuss these findings with respect to current cognitive psychological and media psychological theories.

Embodied individual differences in emotional intensity
Creators: name: Perry, Jennifer M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: The present study took an individual differences approach to understand how peripheral autonomic reactivity and interoceptive ability impact variability in individuals’ emotional intensity. Working under the theory of constructed emotion, we anticipated that interoceptive ability would moderate autonomic reactivity to predict emotional intensity. After using a heartbeat detection task to measure ability to monitor one’s own heart rate, we induced negative affect using the Trier Social Stress Test and continuously recorded cardiovascular physiology throughout the task. Through hierarchical regression analyses we found that while interoceptive ability significantly predicts both general emotional and high arousal negative emotional intensity, neither autonomic reactivity nor its interaction with interoceptive ability have a significant relationship with emotional intensity. Our findings provide support to the idea that emotions are constructed by applying conceptual knowledge to internal and external stimuli, rather than arising from physiological responses alone.

description: In this paper, we consider logarithmic and exponential forms of nonlinear electrodynamics as a source and obtain magnetic brane solutions of the Lovelock gravity. Although these solutions have no curvature singularity and no horizon, they have a conic singularity with a deficit angle. We investigate the effects of nonlinear electrodynamics and the Lovelock gravity on the value of deficit angle and find that various terms of Lovelock gravity do not affect deficit angle. Next, we generalize our solutions to spinning cases with maximum rotating parameters in arbitrary dimensions and calculate the conserved quantities of the solutions. Finally, we consider nonlinear electrodynamics as a correction of the Maxwell theory and investigate the properties of the solutions.

We formulate the problem by using the time scales theory so that the results can be applied to any uniform or non-uniform time domains. Also, we provide a comparison of results that shows that obtained results are unified and generalize the existing results. Mainly, we use the unified matrix-measure theory and Halanay inequality to establish these results. In the last section, we provide two simulated examples for different time domains to show the effectiveness and generality of the obtained analytical results.

Socioeconomic Status, Perceived Resources, and Susceptibility to Sickness Suggestions: Investigating Whether a Manipulation of Socioeconomic Status Influences Susceptibility to the Nocebo Effect
Creators: name: Jones, Katelyn R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Because individuals with low socioeconomic status (SES) are exposed to greater stressors and
perceive having more limited resources, they may be far more susceptible to the nocebo effect
than individuals with higher SES. The nocebo effect is a negative reaction to the suggestion that
a person may feel unpleasant, despite no environmental reason why this suggestion alone should
induce a negative state. I examined the effects of a nocebo suggestion and social status on health
symptoms. After administering my nocebo—a suggestion that dust in the lab environment was
potentially harmful—I manipulated participants’ subjective social status. We then examined
reported health symptoms. My data indicated that being low in subjective SES resulted in greater
health symptoms when a nocebo was not delivered. This nocebo effect was actually stronger
among those in the low subjective SES condition than among those in the high subjective SES
condition. Overall, the findings provide unique insight into the nature of SES and the nocebo
effect, and the implications of the findings are discussed.

Especially the experienced illusions of body ownership of avatars and of being in the virtual environment (spatial presence) have been discussed in this context. This study investigated a Proteus effect of avatar age on post-embodiment walking speed, with special focus on how body ownership and spatial presence moderated this effect. Participants who had previously embodied older avatars took significantly longer to walk a set distance than either young avatar or control group participants. This was only apparent during the first half of the walking phase, which may indicate fast decay rates of the effect after embodiment ended. The reported body ownership could not be shown to impact the strength of the Proteus effect. Participants reporting more pronounced spatial presence were subject to stronger Proteus effects, with only the two-thirds of the sample with higher spatial presence showing evidence of the effect.

description: We study the stability of a spherically symmetric perturbation around the flat Friedmann-Lema$\hatı$tre-Robertson-Walker spacetime in the ghost-free bigravity theory, retaining nonlinearities of the helicity-$0$ mode of the massive graviton. It has been known that, when the graviton mass is smaller than the Hubble parameter, homogeneous and isotropic spacetimes suffer from the Higuchi-type ghost or the gradient instability against the linear perturbation in the bigravity. Hence, the bigravity theory has no healthy massless limit for cosmological solutions at linear level. In this paper we show that the instabilities can be resolved by taking into account nonlinear effects of the scalar graviton mode for an appropriate parameter space of coupling constants. The growth history in the bigravity can be restored to the result in general relativity in the early stage of the Universe, in which the Stückelberg fields are nonlinear and there is neither ghost nor gradient instability. Therefore, the bigravity theory has the healthy massless limit, and cosmology based on it is viable even when the graviton mass is smaller than the Hubble parameter.

description: Let k be a perfect field of characteristic p > 0, and let G be a finite group. We consider the pointed G-curves over k associated by Harbater, Katz, and Gabber to faithful actions of G on k[[t]] over k. We use such "HKG G-curves" to classify the automorphisms of k[[t]] of p-power order that can be expressed by particularly explicit formulas, namely those mapping t to a power series lying in a Z/pZ Artin-Schreier extension of k(t). In addition, we give necessary and sufficient criteria to decide when an HKG G-curve with an action of a larger finite group J is also an HKG J-curve.

description: This research considers the problem of identifying safety constraints and developing Run Time Assurance (RTA) for Deep Reinforcement Learning (RL) Tactical Autopilots that use neural network control systems (NNCS). This research studies a specific use case of an NNCS performing autonomous formation flight while an RTA system provides collision avoidance and geofence assurances. First, Systems Theoretic Accident Models and Processes (STAMP) is applied to identify accidents, hazards, and safety constraints as well as define a functional control system block diagram of the ground station, manned flight lead, and surrogate unmanned wingman. Then, Systems Theoretic Process Analysis (STPA) is applied to the interactions of the the ground station, manned flight lead, surrogate unmanned wingman, and internal elements of the wingman aircraft to identify unsafe control actions, scenarios leading to each, and safety requirements to mitigate risks. This research is the first application of STAMP and STPA to an NNCS bounded by RTA.

description: Trigonometric Rosen-Morse Potential is employed as a mesonic potential interaction. The extended Nikiforov-Uvarov method is used to solve the N-radial Fractional Schrodinger equation analytically. Using the generalized fractional derivative, the energy eigenvalues are obtained in the fractional form. The current findings are used to calculate the masses of mesons such as charmonium, bottomonium, and heavy-light mesons. The current findings are superior to those of other recent studies and show good agreement with experimental data as a result, the fractional parameter is crucial in optimizing meson masses.

The Cost and Causes of Medication Omission Errors: A Discussion and Literature Review
Creators: name: Duda, Michael
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Medication errors are a constant source of strife to both patients and healthcare providers
alike since time immemorial. Regardless of our level of technology, the fallible nature of humans
makes medication errors a common occurrence in healthcare. One type of medication error that
can often be overlooked is the omission error. An omission error occurs when a patient does not
receive a medication without a justification for that omission.
Few healthcare providers would argue that medication errors do not contribute greatly to
hospitalization costs. Unfortunately, because most medication errors are reported on a voluntary
basis, it is extremely difficult to accurately estimate the total cost (Choi, Lee, Flynn, Kim, Lee,
Kim, & Suh, 2016). Estimates vary widely and are often unique to the healthcare system that
they occur in due to methodology used to classify and study the data (Choi et al., 2016). Few
data exist on medication omission errors (MOEs) exclusively, despite this type of error being one
of the most common kind of errors (Grissinger, 2017). Two prior literature reviews on
medication errors found multiple contradictory causes, however, some common themes will be
explored in this review (Lassetter & Warnick, 2003; Berdot et al., 2015). This discussion and
literature review examines the existing data on the causes, and the costs associated with
medication omission errors.
Techniques in Iterative Proton CT Image Reconstruction

description: This is a review paper on some of the physics, modeling, and iterative algorithms in proton computed tomography (pCT) image reconstruction. The primary challenge in pCT image reconstruction lies in the degraded spatial resolution resulting from multiple Coulomb scattering within the imaged object. Analytical models such as the most likely path (MLP) have been proposed to predict the scattered trajectory from measurements of individual proton location and direction before and after the object. Iterative algorithms provide a flexible tool with which to incorporate these models into image reconstruction. The modeling leads to a large and sparse linear system of equations that can efficiently be solved by projection methods-based iterative algorithms. Such algorithms perform projections of the iterates onto the hyperlanes that are represented by the linear equations of the system. They perform these projections in possibly various algorithmic structures, such as block-iterative projections (BIP), string-averaging projections (SAP). These algorithmic schemes allow flexibility of choosing blocks, strings, and other parameters. They also cater for parallel implementations which are apt to further save clock time in computations. Experimental results are presented which compare some of those algorithmic options.

Compressed simulation of thermal and excited states of the 1-D XY-model

description: Since several years the preparation and manipulation of a small number of quantum systems in a controlled and coherent way is feasible in many experiments. In fact, these experiments are nowadays commonly used for quantum simulation and quantum computation. As recently shown, such a system can, however, also be utilized to simulate specific behaviors of exponentially larger systems. That is, certain quantum computations can be performed by an exponentially smaller quantum computer. This compressed quantum computation can be employed to observe for instance the quantum phase transition of the 1D XY-model using very few qubits. We extend here this notion to simulate the behavior of thermal as well as excited states of the 1D XY-model. In particular, we consider the 1D XY-model of a spin chain of n qubits and derive a quantum circuit processing only $\mathrm{log}(n)$ qubits which simulates the original system. We demonstrate how the behavior of thermal as well as any eigenstate of the system can be efficiently simulated in this compressed fashion and present a quantum circuit on $\mathrm{log}(n)$ qubits to measure the magnetization, the number of kinks, and correlations occurring in the thermal as well as any excited state of the original systems. Moreover we derive compressed circuits to study time evolutions.

description: Excitonic emission from atomically precise graphene nanoribbons (GNRs) synthesised on a metal surface is probed with atomic-scale spatial resolution using a scanning tunneling microscopy (STM) approach. A STM-based strategy to transfer the GNRs to a partially insulating surface is used to prevent light emission quenching of the ribbons by the metal substrate. Sub-nanometer resolved STM-induced fluorescence spectra reveal emission from localized dark excitons build upon the topological end states of the GNRs. A low frequency vibronic emission comb whose characteristics change with the GNR length is attributed to longitudinal acoustic modes confined to a finite box. Overall, our study provides a novel path to investigate the interplay between excitons, vibrons and topology in atomically precise graphene nanostructures.
