description: On the basis of the perturbation formulas for a $d^{1}$ configuration ion in a tetragonal crystal field, the three optical absorption bands and electron paramagnetic resonance (EPR) parameters ($g$ factors $g_{i}$ and hyperfine structure constants $A_{i}$ for $i = \|$ and $\perp$, respectively) of VO$^{2+}$ in Na$_{3}$C$_{6}$H$_{5}$O$_{7}\cdot2$H$_{2}$O single crystals were studied using the perturbation theory method. By simulating the calculated optical and EPR spectra to the observed values, local structure parameters and negative signs of the hyperfine structure constants $A_{i}$ of the octahedral (VO$_{6}$)$^{8-}$ cluster in trisodium citrate dehydrate single crystal can be obtained.

description: Complex metrics are a double-edged sword: they allow one to replace singular spacetimes, such as those containing a big bang, with regular metrics, yet they can also describe unphysical solutions in which quantum transitions may be more probable than ordinary classical evolution. In the cosmological context, we investigate a criterion proposed by Witten (based on works of Kontsevich & Segal and of Louko & Sorkin) to decide whether a complex metric is allowable or not. Because of the freedom to deform complex metrics using Cauchy's theorem, deciding whether a metric is allowable in general requires solving a complicated optimisation problem. We describe a method that allows one to quickly determine the allowability of minisuperspace metrics. This enables us to study the off-shell structure of minisuperspace path integrals, which we investigate for various boundary conditions. Classical transitions always reside on the boundary of the domain of allowable metrics, and care must be taken in defining appropriate integration contours for the corresponding gravitational path integral. Perhaps more surprisingly, we find that proposed quantum (`tunnelling') transitions from a contracting to an expanding universe violate the allowability criterion and may thus be unphysical. No-boundary solutions, by contrast, are found to be allowable, and moreover we demonstrate that with an initial momentum condition an integration contour over allowable metrics may be explicitly described in arbitrary spacetime dimensions.

description: The United States Army consists of over 1 million members, many of whom will encounter hazardous noise levels at various times during their service. The U.S. entered an extended period of armed conflict in 2002, subjecting larger numbers of Service Members to hazardous noise. In 2006, the U.S. Army Office of the Surgeon General issued a directive that all Active Duty (AD) Army Service Members would have their hearing readiness tracked via the Medical Protection System (MEDPROS), allowing leaders and commanders closer and more complete surveillance of hearing than was afforded previously. The current study focuses on the effects of this policy as measured by rates of Significant Threshold Shift (STS) and rates of hearing loss. Results indicate that rates of STS and hearing loss decreased significantly in the time frame following the policy implementation for all pay grade classes and for the job types most often subjected to excessive noise levels. Significant differences are noted between the decrease in STS rates of Enlisted Service Members and those of Officers. However, no significant difference is noted in the amount of decrease across job types.

description: In the year 2002 publications of A.V.M. Khachatourian and A.O. Wistrom were released, in which the existence of an electrostatic torque has been claimed. This moment of force should act in a three sphere configuration, where one sphere is held at a constant electric potential. This claim was based on an observed rotation and was supported by a mathematical solution derived by Wistrom and Khachatourian. The theoretical work of Wistrom and Khachatourian as well as the interpretation of the observed rotation were criticized by several scientists who offered alternative explanations for the rotation. We therefore designed an experimental setup which enabled us to investigate the phenomenon. By performing numerous measurements, we showed that the rotation is due to asymmetric mass distribution within the sphere, which is dislocated due to electrostatic forces between the spheres. We were able to clear our measurements from this effect and observed a null result more than two orders of magnitude smaller than predicted by Khachatourian and Wistrom's theory. We therefore showed that the rotation doesn't occur in an electrostatic system within the resolution of our experiment.

description: We reveal that quadrature squeezing can result in significantly better quantum-estimation performance with quantum heterodyne detection (of H. P. Yuen and J. H. Shapiro) as compared to quantum homodyne detection for Gaussian states, which touches an important aspect in the foundational understanding of these two schemes. Taking single-mode Gaussian states as examples, we show analytically that the competition between the errors incurred during tomogram processing in homodyne detection and the Arthurs-Kelly uncertainties arising from simultaneous incompatible quadrature measurements in heterodyne detection can often lead to the latter giving more accurate estimates. This observation is also partly a manifestation of a fundamental relationship between the respective data uncertainties for the two schemes. In this sense, quadrature squeezing can be used to overcome intrinsic quantum-measurement uncertainties in heterodyne detection.

Year: 2004

description: In the wake of the 2004 shortage, the current system of influenza vaccine development, supply, and distribution has been called into question, as has been the management of the process by federal, state, and municipal government agencies. There are increasing calls for heightened government scrutiny of the process emanating from many quarters, although some conservatives regard the issue as evidence that fear of lawsuits has stymied the otherwise natural functionality of the free market. At the current juncture, although it remains unclear what the exact policy implications of the vaccine shortage will be in the long-term, it is abundantly clear that this issue, recently thrust into the public discourse, requires significant remediation.

description: We compute the graybody factor and evaporation rate of a rotating black hole in the presence of a hypothetical reflective surface slightly outside the outer horizon radius, assuming that it spontaneously emits thermal radiation due to quantum-gravitational effects such as firewalls or stretched horizons. As a result of a resonance caused by a cavity between the reflective surface and angular momentum barrier, the graybody factor is subject to a modulation in the frequency space. By taking into account this effect for multiangular modes of neutrinos, photons, and gravitons, we numerically compute the time development of the mass and angular momentum of the black hole, and show that the excited reflective surface shortens the lifetime of quantum black holes.

description: A numerical study of two-dimensional flow past a confined circular cylinder with slip wall is performed. A dimensionless number, Knudsen number ($Kn$) is used to describe the slip length of cylinder wall. The Reynolds number ($Re$) and Knudsen number ($Kn$) ranges considered are $Re = [1, 180]$ and $Kn = [0, \infty)$, respectively. Time-averaged flow separation angle ($\bar{θ_s}$), dimensionless recirculation length ($\bar{L_s}$) and the tangential velocity ($\bar{u_τ}$) distributed on the cylinder's wall, drag coefficient ($\bar{C_d}$) and drag reduction ($DR$) are investigated. The time-averaged tangential velocity distribution on the cylinder's wall fit well with the formula $\bar{u_τ} = [\fracα{1+βe^{-γ(π-θ)}}+δ]sin(θ) $, where the coefficients ($α$, $β$, $γ$, $δ$) are related with $Re$ and $Kn$. Several scaling-laws are found, $log(\bar{u_{τmax}})\sim{log(Re)}$ and $\bar{u_{τmax}}\sim{Kn}$ for low $Kn$, ($\bar{u_{τmax}}$ is the maximum tangential velocity on the cylinder's wall), $log(DR)\sim{log(Re)}$ ($Re\leq45$ and $Kn\leq0.1$), $log(DR)\sim{log(Kn)}$ ($Kn\leq0.05$). At low $Re$, $DR_v$ (the friction drag reduction) is the main source of $DR$. However, $DR_p$ (the differential pressure drag reduction) contributes the most to $DR$ at high $Re$ ($Re>\sim60$) and $Kn$ over a critical number. $DR_v$ is found almost independent to $Re$.

Recommendations for Strategies to Improve Adherence to Treatment for Latent Tuberculosis Infections

Year: 2016

description: While significant progress has been made toward the elimination of tuberculosis in the United States (U.S.), it remains a public health problem in other parts of the world (Centers for Disease Control and Prevention [CDC], 2016a). Completion of Latent Tuberculosis Infection (LTBI) treatment is essential to controlling and eliminating tuberculosis (TB). Treatment completion is determined by the number of doses ingested over a given period of time. Adherence to LTBI treatment is important because it can improve the control of disease transmission and it is a key strategy to reduce TB disease incidence in industrialized countries. A literature review was conducted to assess ways to improve adherence to LTBI treatment and provide recommendations for implementation. The evaluation focused on three main strategies-healthcare provider-centered, clinic-centered, and patient-centered-to find ways to improve adherence to LTBI treatment regimens. Based on the results of the studies evaluated, directly observed therapy (DOT) showed an increase in adherence to LTBI treatment of approximately 70-80% especially when used in conjunction with other patient-centered strategies and innovative treatment regimens. DOT is when qualified healthcare staff observe TB patients taking their TB medication to ensure adherence to treatment; therefore, a recommendation is that DOT along with innovative regimens and patient-centered strategies be implemented to improve adherence.

description: New light fundamental fields are natural candidates for all or a fraction of dark matter. Self-gravitating structures of such fields might be common objects in the universe, and could comprise even galactic halos. These structures would interact gravitationally with black holes, a process of the utmost importance since it dictates their lifetime, the black hole motion, and possible gravitational radiation emission. Here, we study the dynamics of a black hole piercing through a much larger fully relativistic boson star, made of a complex minimally coupled massive scalar without self-interactions. As the black hole pierces through the bosonic structure, it is slowed down by accretion and dynamical friction, giving rise to gravitational-wave emission. Since we are interested in studying the interaction with large and heavy scalar structures, we consider mass ratios up to $q\sim 10$ and length ratios ${\cal L} \sim 62$. Somewhat surprisingly, for all our simulations, the black hole accretes more than 95% of the boson star material, even if an initially small black hole collides with large velocity. This is a consequence of an extreme "tidal capture" process, which binds the black hole and the boson star together, for these mass ratios. We find evidence of a "gravitational atom" left behind as a product of the process.

description: Average-atom models are an important tool in studying matter under extreme conditions, such as those conditions experienced in planetary cores, brown and white dwarfs, and during inertial confinement fusion. In the right context, average-atom models can yield results with similar accuracy to simulations which require orders of magnitude more computing time, and thus can greatly reduce financial and environmental costs. Unfortunately, due to the wide range of possible models and approximations, and the lack of open-source codes, average-atom models can at times appear inaccessible. In this paper, we present our open-source average-atom code, atoMEC. We explain the aims and structure of atoMEC to illuminate the different stages and options in an average-atom calculation, and to facilitate community contributions. We also discuss the use of various open-source Python packages in atoMEC, which have expedited its development.

Ovarian Cancer: Recommendations for research funding in detection, treatment and prevention
Creators: name: Thedinga, Angela

Year: 2015

description: This year over 230,000 women worldwide will be diagnosed with ovarian cancer, and 150,000 will die from this disease, making ovarian cancer the most lethal gynecologic cancer. While many cancers like lung, breast and prostate cancer have enjoyed amazing progress in the past 50 years, ovarian cancer mortality has remained high due to late detection, lack of novel treatment approaches and lack of prevention options. With the advent of genetic testing, we have an opportunity to reduce mortality by better understanding ovarian cancer contributing factors and developing prevention or early detection measures. Effective screening programs are desperately needed to identify cancer cases before late stage advancement. Lastly, many improved treatment options are currently in clinical trials, including approaches to engage the immune system to better reduce cancerous cell growth. Improving ovarian cancer survival rates will require a shift in how research funds are allocated, shifting government funds from treatment toward researching effective preventing and screening measures.

description: Given a statistical ensemble of quantum states, the corresponding Page curve quantifies the average entanglement entropy associated with each possible spatial bipartition of the system. In this work, we study a natural extension in the presence of a conservation law and introduce the symmetry-resolved Page curves, characterizing average bipartite symmetry-resolved entanglement entropies. We derive explicit analytic formulae for two important statistical ensembles with a $U(1)$-symmetry: Haar-random pure states and random fermionic Gaussian states. In the former case, the symmetry-resolved Page curves can be obtained in an elementary way from the knowledge of the standard one. This is not true for random fermionic Gaussian states. In this case, we derive an analytic result in the thermodynamic limit based on a combination of techniques from random-matrix and large-deviation theories. We test our predictions against numerical calculations and discuss the sub-leading finite-size corrections.

Stranger’s Identity Explored through Contemporary Art Practice: In-Between Mongolia and the UK

Year: 2023
Subjects: Uncategorized

description: The PhD research explored the identities of ‘Stranger’ (Schutz, 1944), ‘Stranger-artist’ and ‘Stranger-Mongolian’ through adopting a semi-autobiographical approach in which I use a variety of practice-based research methodologies in order to produce original art projects and artworks. I used ‘experiential perspective’ (Stevens, 1996) as the main paradigm in inquiring the negotiation process of a necessary adjustment to a different culture, language and society in conjunction with the popular debate of ‘loosing and searching for identity’ (Trinh, 1988). In particular, the research is concerned with the previously untouched subject of a modern Mongolian national identity, its artistic representation and re-identification in the UK, through practice-based contemporary art methodologies. Drawing on examples from the recent political history of Mongolia and mainstream media, combined with first-hand personal experiences of the realities of national, racial, cultural stereotyping, the research has contested the existing stereotype of Mongolness. Important to this has been the inclusion and intertwining of familial and personal narratives in defining ‘Stranger-Mongolian’ identity, and how these experiences have become continually manifested while undertaking four research trips back and forth to Mongolia. I probed the terms Nicolas Bourriaud’s terms ‘cultural nomad’ and ‘reification’ in relation to Non-Western artists’ practices. As part of this I have also reflected upon the not widely known and studied art medium of Mongolian traditional painting or Mongol Zurag and the impact it had on my art practice. The research employed various combinations of methodologies including photography, performances, documentations, installations, videos, interviews and personal narratives, two of which I termed as ‘auto-photo-performance’ and 'photo-performance'. The site-specific and spatial qualities of the research were the prepositions to all of the art projects and artworks produced. The final PhD submission consists of 3 parts: Part 1, Contextual Document; Part 2, Art Projects & Artworks and Part 3, DVD.
Teachers as Gatekeepers in the Prevention of Adolescent Suicide
Creators: name: O'Leary, Sarah A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: Adolescent suicide has increased dramatically over the last 45 years. A flurry of suicide prevention programs were developed and implemented in the 80s, but they have not led to noticeable reductions in the adolescent suicide rates. Schools are frequently the site of prevention programs due to their easy access to students during the school day. The role of teachers as gatekeepers who can identify youth at risk has been undervalued and minimally used, according to surveys available. While there is a lack of evaluation of all suicide prevention programs, gatekeeper training programs have shown promising results. Evidence and advantages for teacher training as gatekeepers is presented along with recommendations for implementing such a program.

description: All-dielectric nanophotonics underpinned by the physics of bound states in the continuum (BICs) have demonstrated breakthrough applications in nanoscale light manipulation, frequency conversion and optical sensing. Leading BIC implementations range from isolated nanoantennas with localized electromagnetic fields to symmetry-protected metasurfaces with controllable resonance quality (Q) factors. However, they either require structured light illumination with complex beam-shaping optics or large, fabrication-intense arrays of polarization-sensitive unit cells, hindering tailored nanophotonic applications and on-chip integration. Here, we introduce radial quasi bound states in the continuum (radial BICs) as a new class of radially distributed electromagnetic modes controlled by structural asymmetry in a ring of dielectric rod pair resonators. The radial BIC platform provides polarization-invariant and tunable high-Q resonances with strongly enhanced near fields in an ultracompact footprint as low as 2 $μ$m$^2$. We demonstrate radial BIC realizations in the visible for sensitive biomolecular detection and enhanced second-harmonic generation from monolayers of transition metal dichalcogenides, opening new perspectives for compact, spectrally selective, and polarization-invariant metadevices for multi-functional light-matter coupling, multiplexed sensing, and high-density on-chip photonics.

A Statistical Method to Search for Recoiling Supermassive Black Holes in Active Galactic Nuclei

description: We propose an observational test for gravitationally recoiling supermassive black holes (BHs) in active galactic nuclei, based on a correlation between the velocities of BHs relative to their host galaxies, |Δv|, and their obscuring dust column densities, Σ_{dust} (both measured along the line of sight). We use toy models for the distribution of recoil velocities, BH trajectories, and the geometry of obscuring dust tori in galactic centres, to simulate 2.5x10^5 random observations of recoiling quasars. BHs with recoil velocities comparable to the escape velocity from the galactic centre remain bound to the nucleus, and do not fully settle back to the centre of the torus due to dynamical friction in a typical quasar lifetime. We find that |Δv| and Σ_ {dust} for these BHs are positively correlated. For obscured (Σ_{dust}>0) and for partially obscured (0=45 km/s, the sample correlation coefficient between log10(|Δv|) and Σ_{dust} is r_{45} = 0.28+/-0.02 and r_{45} = 0.13+/-0.02, respectively. Allowing for random +/-100 km/s errors in |Δv| unrelated to the recoil dilutes the correlation for the partially obscured quasars to r_{45} = 0.026+/-0.004 measured between |Δv| and Σ_{dust}. A random sample of >~3,500 obscured quasars with |Δv|>=45 km/s would allow rejection of the no-correlation hypothesis with 3 sigma significance 95% of the time. Finally, we find that the fraction of obscured quasars, F_{obs}(|Δv|), decreases with |Δv| from F_{obs}(<10 km/s)>~0.8 to F_{obs}(>10^3 km/s)

Training the Honduran Health Alliance Health Promoters: A Program and Evaluation Plan to Increase First-Time Cervical Cancer Screening in Southern Honduras
Creators: name: Marietta, Amy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Cervical cancer is the leading cause of cancer death among women in Honduras. The Honduran Health Alliance (HHA), a student-led organization created in 2002 by medical and public health students from the University of North Carolina at Chapel Hill, aims to reduce the morbidity and mortality associated with cervical cancer among women from six rural communities in Choluteca, the southernmost state of Honduras. There are many factors that determine why a woman may or may not receive screening services from the HHA. In order to assess whether the HHA is most effectively meeting the needs of the target population as it relates to its mission of cervical cancer reduction, the author conducted preliminary research in the communities in question. Research activities included key informant interviews and focus groups with village women to assess the reasons that women in HHA partner communities do or do not attend clinic. Based on the results of this formative research, the HHA would like to propose a more formal health promoter education program by conducting a series of health promoter trainings and setting goals and targets for education and recruitment. The trainings will focus on cervical cancer screening, diagnosis, and treatment information, as well as motivational interviewing techniques and tips for addressing common health beliefs that may keep women from seeking out services. The overall goal of this program is to increase the HHA's ability to effectively reach out to women most in need of the services offered by the HHA and to further its mission of reducing cervical cancer morbidity and mortality among women in this geographic area of Honduras.

description: The PhD research explored the identities of ‘Stranger’ (Schutz, 1944), ‘Stranger-artist’ and ‘Stranger-Mongolian’ through adopting a semi-autobiographical approach in which I use a variety of practice-based research methodologies in order to produce original art projects and artworks. I used ‘experiential perspective’ (Stevens, 1996) as the main paradigm in inquiring the negotiation process of a necessary adjustment to a different culture, language and society in conjunction with the popular debate of ‘loosing and searching for identity’ (Trinh, 1988). In particular, the research is concerned with the previously untouched subject of a modern Mongolian national identity, its artistic representation and re-identification in the UK, through practice-based contemporary art methodologies. Drawing on examples from the recent political history of Mongolia and mainstream media, combined with first-hand personal experiences of the realities of national, racial, cultural stereotyping, the research has contested the existing stereotype of Mongolness. Important to this has been the inclusion and intertwining of familial and personal narratives in defining ‘Stranger-Mongolian’ identity, and how these experiences have become continually manifested while undertaking four research trips back and forth to Mongolia. I probed the terms Nicolas Bourriaud’s terms ‘cultural nomad’ and ‘reification’ in relation to Non-Western artists’ practices. As part of this I have also reflected upon the not widely known and studied art medium of Mongolian traditional painting or Mongol Zurag and the impact it had on my art practice. The research employed various combinations of methodologies including photography, performances, documentations, installations, videos, interviews and personal narratives, two of which I termed as ‘auto-photo-performance’ and 'photo-performance'. The site-specific and spatial qualities of the research were the prepositions to all of the art projects and artworks produced. The final PhD submission consists of 3 parts: Part 1, Contextual Document; Part 2, Art Projects & Artworks and Part 3, DVD.

description: We prove that arithmetic quantum unique ergodicity holds on compact arithmetic quotients of $GL(2,\mathbb{Q}_p)$ for automorphic forms belonging to the principal series. We interpret this conclusion in terms of the equidistribution of eigenfunctions on covers of a fixed regular graph or along nested sequences of regular graphs. Our results are the first of their kind on any p-adic arithmetic quotient. They may be understood as analogues of Lindenstrauss's theorem on the equidistribution of Maass forms on a compact arithmetic surface. The new ingredients here include the introduction of a representation-theoretic notion of "p-adic microlocal lifts" with favorable properties, such as diagonal invariance of limit measures, the proof of positive entropy of limit measures in a p-adic aspect, following the method of Bourgain--Lindenstrauss, and some analysis of local Rankin--Selberg integrals involving the microlocal lifts introduced here as well as classical newvectors. An important input is a measure-classification result of Einsiedler--Lindenstrauss.

description: Sickle cell disease (SCD) remains an important public health problem. Predominantly affecting African Americans, SCD is associated with significant health, financial, and psychosocial costs. Therefore, it is vital to find new ways to improve delivery of care to this patient population. The hospital blood bank plays a key role in delivering transfusion therapy to SCD patients. Because transfusion therapy represents the mainstay of treatment for most SCD patients, we hypothesized that a systematic review of blood bank practices for these patients might uncover new opportunities to improve this care. Current blood bank practices for SCD patient have not been previously described. This paper discusses blood bank practices for SCD patients in North Carolina. The layout is as follows. First, the underlying cause, history, and costs of sickle cell disease are described. Next, evidence supporting the use of transfusions for SCD management and its associated risks are considered. Data from a crosssectional study of NC blood bank practices for SCD patients are then presented. Finally, the significance and implications of this research are discussed.
Electron-acoustic phonon field induced tunnel scattering

description: Theory of electron-acoustic single phonon scattering has been reconsidered. It is assumed that the non-degenerate semiconductor has a spherical parabolic band structure. In the basis of the reconsideration there is a phenomenon of the tilting of semiconductor bands by the perturbing potential of an electric field. In this case, electron eigenfunctions are not plane waves or Bloch functions. In low-field regime, the expressions for electron intraband transition probability and scattering time are obtained under elastic collision approximation. Dependencies of scattering time on electron energy and uniform electric field are analyzed. The results of corresponding numerical computations for n-Si at 300 K are presented. It is established that there is no fracture on the curve of electron scattering time dependence on the electron energy.

description: We present in this paper the SOSpin library, which calculates an analytic decomposition of the Yukawa interactions invariant under any SO(2N) group in terms of an SU(N) basis. We make use of the oscillator expansion formalism, where the SO(2N) spinor representations are expressed in terms of creation and annihilation operators of a Grassmann algebra. These noncommutative operators and their products are simulated in SOSpin through the implementation of doubly-linked-list data structures. These data structures were determinant to achieve a higher performance in the simplification of large products of creation and annihilation operators. We illustrate the use of our library with complete examples of how to decompose Yukawa terms invariant under SO(2N) in terms of SU(N) degrees of freedom for N=2 and 5. We further demonstrate, with an example for SO(4), that higher dimensional field-operator terms can also be processed with our library. Finally, we describe the functions available in SOSpin that are made to simplify the writing of spinors and their interactions specifically for SO(10) models.

description: With the enactment of the Medicaid expansion in the Affordable Care Act (ACA), many individuals in the state of Ohio will remain uninsured due to not being able to afford the option, being an undocumented immigrant, or simply choosing not to purchase it (Kliff, 2013). In Cuyahoga County, the uninsured rate is approximately twelve percent (City of Cleveland, 2014), with Hispanics making up approximately seventeen percent of this population (Community, 2014). The west side of Cleveland has one of the largest concentrations of the Hispanic population in Cleveland, as the Hispanic population makes up forty-seven percent of the neighborhood (City of Cleveland, 2014). This area, known as the Clark-Fulton neighborhood, has thirty-eight percent of its population living in poverty (City of Cleveland, 2014). Scranton Road Ministries Community Development Corporation (CDC), a faith-based nonprofit organization, has recognized the needs of this community, already supplying a legal clinic, after-school programs, and job assistance programs. The organization has held one day health fairs (2004, 2008, 2011, 2012, and 2013) throughout the years, and due to the overwhelming response and needs of the community, a permanent health clinic has been proposed as it aligns with the organization's desire to focus on long-term health impact and outcomes in the community. As a result, this program plan will be used for an establishment of a community health center program aimed at improving the needs of the Clark-Fulton community over the next five years.

description: A new class of multilayered functional materials has recently emerged in which the component atomic layers are held together by weak van der Waals forces that preserve the structural integrity and physical properties of each layer. An exemplar of such a structure is a transistor device in which relativistic Dirac Fermions can resonantly tunnel through a boron nitride barrier, a few atomic layers thick, sandwiched between two graphene electrodes. An applied magnetic field quantises graphene's gapless conduction and valence band states into discrete Landau levels, allowing us to resolve individual inter-Landau level transitions and thereby demonstrate that the energy, momentum and chiral properties of the electrons are conserved in the tunnelling process. We also demonstrate that the change in the semiclassical cyclotron trajectories, following a tunnelling event, is a form of Klein tunnelling for inter-layer transitions.

Lessons Learned through Review of Telemedicine Research in Mental Health
Creators: name: Taylor, Mandrill
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: This paper will serve as a systematic review in investigating the question of whether telemedicine services can resolve the growing global burden of mental illness. Based on disability-adjusted life years (DALYs), unipolar major depression is projected to become the leading cause of disability in the world by 2030 (WHO, 2008). Regrettably, depression is seen nearly 3 to 5 times more often in those persons diagnosed with post-traumatic stress disorder (Kessler et al, 1995). In the setting of natural disaster, terrorism and war-related violence, both diseases must be addressed as a source of increasing concern for every global citizen. In addition to this analysis, discussion and recommendations on further areas of research will be provided. Through a computerized literature search of telepsychiatry across either geopolitical borders or cultural divides in the past ten years, 142 articles were identified. Of those 142 articles, 5 articles met the eligibility criteria of having been screened under the gold-standard diagnostic criteria of either the Diagnostic and Statistical Manual of Mental Disorders (“DSM-IV”) or International Statistical Classification of Disease and Related Health Problems (“ICD-10”). The major flaw of this review was the low statistical power based on the limited amount of research which adhered to gold-standard diagnostic criteria. Along with the 5 articles selected, 33% of the original 142 articles published in the last ten years were also within the past 2 years. Of the 5 articles which met criteria, none were conducted across national borders. In conclusion, future research is needed in the area of cross-border telepsychiatry, specifically in the area of transnational clinical management. In the interim, future systematic reviews may need to include studies of non-DSM/ICD depression and PTSD in order to increase statistical power until more formal psychiatric research is conducted.
