description: Controlling the interaction between localized optical and mechanical excitations has recently become possible following advances in micro- and nano-fabrication techniques. To date, most experimental studies of optomechanics have focused on measurement and control of the mechanical subsystem through its interaction with optics, and have led to the experimental demonstration of dynamical back-action cooling and optical rigidity of the mechanical system. Conversely, the optical response of these systems is also modified in the presence of mechanical interactions, leading to strong nonlinear effects such as Electromagnetically Induced Transparency (EIT) and parametric normal-mode splitting. In atomic systems, seminal experiments and proposals to slow and stop the propagation of light, and their applicability to modern optical networks, and future quantum networks, have thrust EIT to the forefront of experimental study during the last two decades. In a similar fashion, here we use the optomechanical nonlinearity to control the velocity of light via engineered photon-phonon interactions. Our results demonstrate EIT and tunable optical delays in a nanoscale optomechanical crystal device, fabricated by simply etching holes into a thin film of silicon (Si). At low temperature (8.7 K), we show an optically-tunable delay of 50 ns with near-unity optical transparency, and superluminal light with a 1.4 microseconds signal advance. These results, while indicating significant progress towards an integrated quantum optomechanical memory, are also relevant to classical signal processing applications. Measurements at room temperature and in the analogous regime of Electromagnetically Induced Absorption (EIA) show the utility of these chip-scale optomechanical systems for optical buffering, amplification, and filtering of microwave-over-optical signals.

description: The thermal conductivity of suspended single-layer graphene was measured as a function of temperature using Raman scattering spectroscopy on clean samples prepared directly on a prepatterned substrate by mechanical exfoliation without chemical treatments. The temperature at the laser spot was monitored by the frequency of the Raman 2$D$ band of the Raman scattering spectrum, and the thermal conductivity was deduced by analyzing heat diffusion equations assuming that the substrate is a heat sink at ambient temperature. The obtained thermal conductivity values range from $\sim$1800 Wm$^{-1}$K$^{-1}$ near 325 K to $\sim$710 Wm$^{-1}$K$^{-1}$ at 500 K.

Activation and modulation of GABA(B) receptor systems in physiogenic and pathophysiological conditions
Creators: name: Pitman, Kimberley Anne
Publisher: name: University of British Columbia
Year: 2015

description: γ-aminobutyric acid (GABA) is a major inhibitory neurotransmitter in the central nervous system. This thesis explores the actions of known or proposed agonists for the GABA type B (GABA(B)) receptor in isolated cells and on nerve terminals releasing dopamine in rodents. The first chapter provides the background information for the research undertaken in this thesis. In the second chapter I used whole cell patch clamp electrophysiology to explore the action of the proposed atypical GABA(B) receptor agonist, R-isovaline, at heterologously or natively expressed GABA(B) receptors in isolated cells. I found that R-isovaline did not initiate GABA(B)-mediated K+ currents and did not occlude or enhance the responses of other GABA(B) receptor agonists. Our data suggest that R-isovaline does not act as a direct agonist at GABA(B) receptors. In the third chapter I used fast-scan cyclic voltammetry in brain slices to explore the mechanisms behind GABA(B) modulation of dopamine release in the nucleus accumbens core of mice. The canonical GABA(B) receptor agonist, baclofen, concentration-dependently inhibited dopamine release by a direct action on dopamine neuron terminals. Baclofen-mediated inhibition of release was reduced when dopamine was released by stimulations that mimicked burst firing of dopamine neurons. Baclofen also decreased the probability of dopamine release. I also found that GABA(B) modulation of dopamine release was not altered by a sensitising cocaine treatment. In the fourth chapter I used fast scan cyclic voltammetry to assess whether diet induced obesity or a binge pattern of eating could alter GABA(B) or dopamine D2 receptor mediated regulation of dopamine release in the nucleus accumbens core in rats. The abilities of baclofen and the D2 agonist quinpirole to inhibit dopamine release were unchanged by long term access to a palatable cafeteria diet. Chapter 5 discusses the main findings of these experiments and potential future experiments.
Two Proposals for Robust PCA using Semidefinite Programming

subject: FOS: Computer and information sciences

description: The performance of principal component analysis (PCA) suffers badly in the presence of outliers. This paper proposes two novel approaches for robust PCA based on semidefinite programming. The first method, maximum mean absolute deviation rounding (MDR), seeks directions of large spread in the data while damping the effect of outliers. The second method produces a low-leverage decomposition (LLD) of the data that attempts to form a low-rank model for the data by separating out corrupted observations. This paper also presents efficient computational methods for solving these SDPs. Numerical experiments confirm the value of these new techniques.

description: For the first time, time-dependent internal charge amplification through impact ionization has been observed in a planar germanium (Ge) detector operated at cryogenic temperature. In a time period of 30 and 45 minutes after applying a bias voltage, the charge energy corresponding to a baseline of the 59.54 keV $γ$ rays from a $^{241}$Am source is amplified for a short period of time and then decreases back to the baseline. The amplification of charge energy depends strongly on the applied positive bias voltage with drifting holes across the detector. No such phenomenon is visible with drifting electrons across the detector. We find that the observed charge amplification is dictated by the impact ionization of charged states, which has a strong correlation with impurity level and applied electric field. We analyze the dominant physics mechanisms that are responsible for the creation and the impact ionization of charged states. Our analysis suggests that the appropriate level of impurity in a Ge detector can enhance charge yield through the impact ionization of charged states to achieve extremely low-energy detection threshold ($<$ 10 meV) for MeV-scale dark matter searches if the charge amplification can be stabilized.

We find theoretically that the K^- -K^- repulsion plays no significant role in reducing the density and binding energy of K^-K^-pp and that, when two Λ(1405) resonances are produced simultaneously in a short-range p+p collision, they act as doorways to copious formation of K^-K^-pp, if and only if K^-K^-pp is a dense object, as predicted.

description: Bertrand's theorem in classical mechanics of the central force fields attracts us because of its predictive power. It categorically proves that there can only be two types of forces which can produce stable, circular orbits. In the present article an attempt has been made to generalize Bertrand's theorem to the central force problem of relativistic systems. The stability criterion for potentials which can produce stable, circular orbits in the relativistic central force problem has been deduced and a general solution of it is presented in the article. It is seen that the inverse square law passes the relativistic test but the kind of force required for simple harmonic motion does not. Special relativistic effects do not allow stable, circular orbits in presence of a force which is proportional to the negative of the displacement of the particle from the potential center.

Type locality. Cape Colony (no exact locality).
Type material examined. None. Type specimen may be lost, it was not found at any South African museum.
Remarks. We have not seen the type specimen of this species at any of the South African museum throughout our study, thus we support Frolov & Scholtz (2005) assumption that the type specimen of this species may be lost. However, Péringuey in his original description (1901: 300) mentioned that the length of the specimen is 12.75 mm and the width is 8.5 mm. The species is different from its congeners in that it has a remarkable retuse and lobate pronotum in front and the absence of elytral stria 9. In his description, Péringuey (1901) added that the species has dense, equally distant and close pronotal punctures with the presence of deep impression antero-laterally.
The absence of elytral stria 9 is not known among Macroderes species, however, other above mentioned characteristics put the species in close similarity to M. bias. Frolov & Scholtz (2005) suggested that the species might be “an aberrant specimen” of M. bias and attributed the absence of elytral stria 9 to uncompleted separation of the striae from each other.

description: Tumor heterogeneity provides a major challenge for the clinical treatment of breast cancer and is associated with poor patient prognosis and treatment failure. Heterogeneity of the tumor microenvironment and cancer cell phenotypes can result in nonuniform drug delivery and varying tumor response. The purpose of this dissertation is to develop novel methods for the quantitative characterization of tumor heterogeneity using noninvasive imaging, and then employ these methods to measure longitudinal changes in intratumoral heterogeneity in response to treatment. This objective is addressed in three parts. First, in a murine xenograft model of HER2+ breast cancer, we quantify temporal alterations of vascular, cellular, and hypoxic heterogeneity in response to the HER2 targeted therapy, trastuzumab. The results indicate that trastuzumab induces longitudinal increases in cellular and vascular heterogeneity, and longitudinal decreases hypoxic heterogeneity. Second, using multiparametric MRI data, we identify physiologically-distinct tumor habitats in two preclinical models of breast cancer, and measure the changes in tumor composition over time, in response to targeted or cytotoxic therapy. We identify tumor habitats associated with treatment response in both models of breast cancer and provide biological validation of the identified habitats using immunohistochemistry. Finally, in an effort to elucidate intertumoral heterogeneity, we utilize tumor habitats to classify HER2+ xenograft tumors into two tumor imaging phenotypes at baseline and measure the longitudinal response of each phenotype to targeted and cytotoxic therapies. The two tumor phenotypes progress and respond to therapeutic intervention differently, as one phenotype demonstrates more “therapy-sensitive” behavior, with significant decreases in tumor volume and increases in low-vascularity low-cellularity habitats in response to treatment. Overall, our results offer a novel methodology to quantify the spatiotemporal alterations in intratumoral heterogeneity in response to therapeutic intervention using clinically-translatable imaging technologies.

description: The long search for insulating materials that possess low-energy quasiparticles carrying electron's quantum numbers except charge - inspired by the neutral spin-1/2 excitations, the so-called spinons, exhibited by Anderson's resonating-valence-bond state - seems to have reached a turning point after the discovery of several Mott insulators displaying same thermal and magnetic properties as metals, including quantum oscillations in a magnetic field. Here, we show that such anomalous behaviour is not inconsistent with Landau's Fermi liquid theory of quasiparticles at a Luttinger surface. That is the manifold of zeros within the Brillouin zone of the single-particle Green's function at zero frequency, and which thus defines the spinon Fermi surface conjectured by Anderson.

Simulated results are compared with the photometric properties of early-type galaxies in the Antlia cluster (Smith Castelli et al. 2008). The good agreement obtained between observations and simulations allows us to use the information provided by the model for unveiling the physical processes that yield the tigh observed CMR.

description: We perform a theoretical investigation into how a two-mode squeezed vacuum state, that has undergone photon loss, can be stored and purified using noiseless amplification with a collection of solid-state qubits. The proposed method may be used to probabilistically increase the entanglement between the two parties sharing the state. The proposed amplification step is similar in structure to a set of quantum scissors. However, in this work the amplification step is realized by a state transfer from an optical mode to a set of solid-state qubits, which act as a quantum memory. We explore two different applications, the generation of entangled many-qubit registers, and the construction of quantum repeaters for long-distance quantum key distribution.

description: Reservoir computing, a recurrent neural network paradigm in which only the output layer is trained, has demonstrated remarkable performance on tasks such as prediction and control of nonlinear systems. Recently, it was demonstrated that adding time-shifts to the signals generated by a reservoir can provide large improvements in performance accuracy. In this work, we present a technique to choose the time-shifts by maximizing the rank of the reservoir matrix using a rank-revealing QR algorithm. This technique, which is not task dependent, does not require a model of the system, and therefore is directly applicable to analog hardware reservoir computers. We demonstrate our time-shift selection technique on two types of reservoir computer: one based on an opto-electronic oscillator and the traditional recurrent network with a $tanh$ activation function. We find that our technique provides improved accuracy over random time-shift selection in essentially all cases.

description: Control over the integrative self-sorting of metallo-supramolecular assemblies has recently generated significant interest as it opens up possibilities of introducing increased complexity and function into a single self-assembled architecture. Here, the relationship between the geometry of three ligand components and morphology of three self-sorted heteroleptic [Pd2L2Lʹ2]4+ cages is examined. Pd-mediated assembly of two bis-monodentate pyridyl ligands with native bite angles of 75° and 120° affords a cis-[Pd2L2Lʹ2]4+ cage while the same reaction with two ligands bearing bite angles of 75° and 60° forces an anti-conformation for latter ligand, leading to an unprecedented, self-penetrating structural motif; a trans-[Pd2(anti-L)2Lʹ2]4+ heteroleptic cage bearing a “doubly-bridged figure-eight” topology. Each heteroleptic assembly can be accessed through cage-to-cage conversion of their homoleptic precursors, and notably, morphological control of [Pd2L2Lʹ2] cages is achieved through selective ligand displacement transformations in a system of three ligands and at least six possible cage products.
Planetary transit timing variations induced by stellar binarity. The light travel time effect

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: [ABRIDGED] Since the discovery of the first transiting extrasolar planet, transit timing has been recognized as a powerful method to discover and characterize additional planets in these systems. However, the gravitational influence of additional planets is not the only expected source of transit timing variations. In this work, we derive the expected detection frequency of stellar companions of hot-jupiter transiting planets host-stars, detectable by means of transit timing analysis. Since roughly half of the stars in the solar neighborhood belong to binary or multiple stellar systems, the same fraction of binary systems may be expected to be present among transiting planet-host stars, unless planet formation is significantly influenced by the presence of a stellar companion. Transit searches are less affected by the selection biases against long-period binaries that plague radial velocity surveys. If the frequency of binaries among hot-jupiter planets host stars is the same as determined in the solar neighborhood, after 5 years since the discovery of a sample of transiting planets 1.0%+/-0.2% of them have a probability >99% to present transit timing variations >50 sec induced by stellar binarity, and 2.8%+/-0.3% after 10 years, if the planetary and binary orbits are coplanar. Considering the case of random inclinations the probabilities are 0.6%+/-0.1% and 1.7%+/-0.2% after 5 and 10 years respectively. Our estimates can be considered conservative lower limits, since we have taken into account only binaries with periods P>5x10^3 days (a>=6 AU). Our simulations indicate that transit timing variations due to the light travel time effect allow discovery of stellar companions up to maximum separations equal to a\sim36 AU after 5 years since the discovery of the planet (a\sim75 AU after 10 years).

Design Your Own Flow Cytometry Experiment: A Four-Week Inquiry Laboratory

Publisher: name: QUBES Educational Resources

description:
Due to its importance to the field, flow cytometry should be one of the hallmark methods a student learns in the lab portion of an undergraduate immunology course. Flow cytometry is a classic lab technique utilized within immunology and molecular biology research, as well as clinical laboratories to isolate cell populations from harvested tissue stained with a combination of antibodies to cell-specific markers. Despite its importance, instructions on how to complete lab exercises involving flow cytometry largely remain in primary literature articles without the level of detail necessary to teach the lab with ease, especially for those instructors without prior advanced flow cytometry knowledge. In this regard, this Lesson aims to provide clear, easy to follow instructions for how to successfully bring flow cytometry experiments to an undergraduate immunology, cell, or molecular biology teaching lab. In this Lesson, I describe a four-week lab module I teach in my upper-level undergraduate immunology course each fall. Students design and conduct their own experiment to address an immunological question of their choice using flow cytometry. Through this experience, they develop a greater understanding of the cellular makeup of the immune tissues they stain and analyze as the students work to answer a testable hypothesis and communicate their findings by writing a lab report and giving an oral presentation. Overall, this lab allows students to increase their knowledge of flow cytometry and what is necessary to conduct a realistic research experience to answer biological questions within immunology.

description: The boundaries of galaxy groups and clusters are defined by the interplay between the Newtonian attractive force and the decoupling from the local expansion of the Universe. This work extends the definition of a zero radial acceleration surface (ZRAS) and the turnaround surface (TS) for a general distribution of the masses in an expanding background, governed by the cosmological constant. We apply these definitions to different galaxy groups in the local Universe, mapping these groups up to ten megaparsec distances. We discuss the dipole and the quadrupole rate for the Local Group of Galaxies and the implementations on the Hubble diagram correction and galaxy groups virialization. With these definitions, we present the surfaces showing the interplay between the local expansion vs the local Newtonian attraction for galaxy groups in the local Universe. Further, we estimate the masses of different galaxy groups and show that the inclusion of the Cosmological Constant in the analysis predicts these masses to be higher by 5-10\%. For instance the Local Group of Galaxies is estimated to be $(2.47 \pm 0.08) \cdot 10^{12} M_{\odot}$. For the groups with enough tracers close to the TS, the contribution of the Cosmological Constant makes the masses to be even higher. The results show the importance of including the local cosmic expansion in analyzing the Cosmic Flow of the local Universe.

description: Aims. The predictions of the ellipticity of the dark matter halos from models of structure formation are notoriously difficult to test with observations. A direct measurement would give important constraints on the formation of galaxies, and its effect on the dark matter distribution in their halos. Here we show that galaxy-galaxy flexion provides a direct and potentially powerful method for determining the ellipticity of (an ensemble of) elliptical lenses. Methods. We decompose the spin-1 flexion into a radial and a tangential component. Using the ratio of tangential-to- radial flexion, which is independent of the radial mass profile, the mass ellipticity can be estimated. Results. An estimator for the ellipticity of the mass distribution is derived and tested with simulations. We show that the estimator is slightly biased. We quantify this bias, and provide a method to reduce it. Furthermore, a parametric fitting of the flexion ratio and orientation provides another estimate for the dark halo ellipticity, which is more accurate for individual lenses Overall, galaxy-galaxy flexion appears as a powerful tool for constraining the ellipticity of mass distributions.

description: The first part of the paper is devoted to two descriptions of all polynomial tau-functions of the KP hierarchy: by a generalized Jacobi-Trudy formula, and a generalized Giambelli formula. We use the latter formula in the second part to obtain all polynomial tau-functions of the CKP hierarchy and its n-reductions. In particular, for n=3 we find all polynomial tau-functions of the Kaup-Kupershmidt hierarchy.

description: Performing propagating spin-wave spectroscopy of thin films at millikelvin temperatures is the next step towards the realisation of large-scale integrated magnonic circuits for quantum applications. Here we demonstrate spin-wave propagation in a $100\,\mathrm{nm}$-thick yttrium-iron-garnet film at the temperatures down to $45 \,\mathrm{mK}$, using stripline nanoantennas deposited on YIG surface for the electrical excitation and detection. The clear transmission characteristics over the distance of $10\,μ\mathrm{m}$ are measured and the subtracted spin-wave group velocity and the YIG saturation magnetisation agree well with the theoretical values. We show that the gadolinium-gallium-garnet substrate influences the spin-wave propagation characteristics only for the applied magnetic fields beyond $75\,\mathrm{mT}$, originating from a GGG magnetisation up to $47 \,\mathrm{kA/m}$ at $45 \,\mathrm{mK}$. Our results show that the developed fabrication and measurement methodologies enable the realisation of integrated magnonic quantum nanotechnologies at millikelvin temperatures.

description: We present the technical design and characteristics of the magnetic shield developed for 20" PMTs of the low-background OSIRIS facility. A ribbon of amorphous alloy with the extreme magnetic permeability was used in its design providing the excellent efficiency in screening the Earth's magnetic field with a relatively small amount of the material. The mass of materials is crucial for the construction of low-background facilities from the point of view of radioactive backgrounds. Using amorphous materials is cost-efficient compared to other methods for screening the Earth's magnetic field.

description: We use the long-wavelength effective theory of black branes (blackfold approach) to perturbatively construct holographic duals of the vacua of the $\mathcal{N}=1$* supersymmetric gauge theory. Employing the mechanism of Polchinski and Strassler, we consider wrapped black five-brane probes with D3-brane charge moving in the perturbative supergravity backgrounds corresponding to the high and low temperature phases of the gauge theory. Our approach recovers the results for the brane potentials and equilibrium configurations known in the literature in the extremal limit, while away from extremality we find metastable black D3-NS5 configurations with horizon topology $\mathbb{R}^3\times \mathbb{S}^2\times\mathbb{S}^3$ in certain regimes of parameter space, which cloak potential brane singularities. We uncover novel features of the phase diagram of the $\mathcal{N}=1$* gauge theory in different ensembles and provide further evidence for the appearance of metastable states in holographic backgrounds dual to confining gauge theories.

description: Starting from the equations of collisionless linear gyrokinetics for magnetised plasmas with an imposed inhomogeneous magnetic field, we present the first known analytical, closed-form solution for the resulting velocity-space integrals in the presence of resonances due to both parallel streaming and constant magnetic drifts. These integrals are written in terms of the well-known plasma dispersion function (Faddeeva & Terentev 1954; Fried & Conte 1961), rendering the subsequent expressions simpler to treat analytically and more efficient to compute numerically. We demonstrate that our results converge to the well-known ones in the straight-magnetic-field and two-dimensional limits, and show good agreement with the numerical solver by Gürcan (2014). By way of example, we calculate the exact dispersion relation for a simple electrostatic, ion-temperature-gradient-driven instability, and compare it with approximate kinetic and fluid models.

A Dynamic Multimedia User-Weight Classification Scheme for IEEE_802.11 WLANs

description: In this paper we expose a dynamic traffic-classification scheme to support multimedia applications such as voice and broadband video transmissions over IEEE 802.11 Wireless Local Area Networks (WLANs). Obviously, over a Wi-Fi link and to better serve these applications - which normally have strict bounded transmission delay or minimum link rate requirement - a service differentiation technique can be applied to the media traffic transmitted by the same mobile node using the well-known 802.11e Enhanced Distributed Channel Access (EDCA) protocol. However, the given EDCA mode does not offer user differentiation, which can be viewed as a deficiency in multi-access wireless networks. Accordingly, we propose a new inter-node priority access scheme for IEEE 802.11e networks which is compatible with the EDCA scheme. The proposed scheme joins a dynamic user-weight to each mobile station depending on its outgoing data, and therefore deploys inter-node priority for the channel access to complement the existing EDCA inter-frame priority. This provides efficient quality of service control across multiple users within the same coverage area of an access point. We provide performance evaluations to compare the proposed access model with the basic EDCA 802.11 MAC protocol mode to elucidate the quality improvement achieved for multimedia communication over 802.11 WLANs.

Plant growth promotion and nitrogen fixation by Paenibacillus polymyxa in corn and canola
Creators: name: Puri, Akshit
Publisher: name: University of British Columbia
Year: 2015

description: Availability of nitrogen is the most yield-limiting mineral factor in crop production. Several Paenibacillus bacterial strains that were able to fix nitrogen from atmosphere were isolated from extracts of surface-sterilized lodgepole pine seedling and tree tissues. One strain, Paenibacillus polymyxa P2b-2R, was found to derive high amounts of nitrogen from the atmosphere when introduced into gymnosperm species, namely lodgepole pine and western red cedar. I wanted to determine if Paenibacillus polymyxa P2b-2R could colonize, fix nitrogen and promote the growth of important agricultural crops such as corn and canola. For this I inoculated corn and canola seeds with P. polymyxa P2b-2R and grew them for 30 and 60 days, respectively. Corn seedlings were harvested 10, 20 and 30 days after inoculation and canola seedlings were harvested 20, 40 and 60 days after inoculation for evaluation of rhizospheric and internal tissue (endophytic) colonization (cfu). Seedlings were also evaluated for biological nitrogen fixation (¹⁵N dilution) and growth promotion (length and biomass) at these harvest intervals. The entire experiment was repeated to confirm the treatment effects. P2b-2R successfully colonized the corn rhizosphere with 5.52 x 10⁶ cfu/g dry root and the canola rhizosphere with 1.08 x 10⁸ cfu/g dry root. P2b-2R also colonized internal tissues of corn and canola root with population densities of 4.54 x 10⁵ cfu/g fresh weight and 2.36 x 10³ cfu/g fresh weight, respectively. Corn seedling growth was promoted significantly by inoculation with P2b-2R with an increase of 35% in length and 31% in biomass, 30 days after inoculation. Similarly, canola seedling length was promoted by 25% and biomass by 30%, 60 days after inoculation. Corn seedlings inoculated with P2b-2R were able to derive about 17% of foliar nitrogen from the atmosphere, 30 days after inoculation. Similarly canola seedlings derived nearly 20% of foliar nitrogen from atmosphere, 60 days after inoculation. These results clearly suggest that Paenibacillus polymyxa P2b-2R might have a broad range host capability and is able to fix nitrogen and promote the growth of at least certain important agricultural crops – corn and canola.
Panoramic radiographs prior to complete denture fabrication : a retrospective study of clinical significance and quality assurance
Creators: name: Kratz, Richard John
Publisher: name: University of British Columbia
Year: 2015

description: Purpose. There are concerns about the burden of ionizing radiation from radiographs, and consequently about the benefits of radiographic screening of edentulous mandibles. The primary aim of this retrospective study was to identify findings on digital panoramic radiographs of edentulous patients to determine how such findings impacted patient management prior to fabrication of complete dentures. Secondarily, a quality assurance assessment of the panoramic radiographs was completed by comparing two groups of students, 2nd year Introduction to Prosthodontics (IPROS) and 3rd/4th year Integrated Clinical Care (ICC), regarding radiographic interpretations completed, positional errors detected, and radiographic interpretation errors made. Methods. Two hundred digital panoramic radiographs taken on edentulous patients were identified from UBC Dentistry clinics between 2006-2012, of which 31 were excluded (clinical crowns or implants present, no digital panoramic present or analog image scanned in). An Oral and Maxillofacial Radiologist provided training and interpretation assistance, and randomly audited 20 panoramic radiographs for an observed proportion of agreement. Results. There were 165 positive radiographic findings, of which 6 (3.6%) affected patient management. 301 positional errors were also identified, with 14 (8.3%) images free of error. There were significantly more (p<0.05) radiographic interpretations completed (p=0.00014) and positional errors correctly identified (p=0.002) in IPROS compared to ICC. No significant difference was observed for radiographic interpretation errors (p=0.059) between the two student groups. Conclusion. The positive radiographic findings (PRFs) identified in the panoramic radiographs of edentulous patients in this study offered minimal benefits, with only 3.6% of PRFs affecting patient management. We would therefore recommend that panoramic radiographic screening for this patient population be discontinued. The rate of positional errors for panoramic radiographs of edentulous patients was high, indicating a need for additional staff training to minimize errors and to maximize diagnostic benefits.
