Schwannoma of the femur: A rare case report
Creators: name: Al-Lhedan, Fahad
Publisher: name: My University
Year: 2017

description: Schwannoma is a benign tumor derived from Schwann cells that cover myelinated nerve fibers (1). Among primary bone tumors, intraosseous schwannoma accounts for less than 0.2% (2). We are reporting a rare case of an 18-year-old female presented with swelling in the posterior right thigh. The patient was asymptomatic and this was incidentally discovered by her massage therapist. However, the swelling was gradually growing since then. The plain radiograph findings were suggestive of a benign bone tumor. MRI with gadolinium was performed for further evaluation but it demonstrated suspicious features as evidenced by the extra osseous enhancing soft tissue component. Three phase bone scan was done thereafter and it showed hyperemia with mild increased uptake of the lesion on the delayed phase. Osteosarcoma was suspected and chest CT was performed for staging purposes which turned out to be negative for metastasis. The lesion was biopsied under ultrasound guidance. The histologic features and the immunohistochemically profile were consistent with a benign schwannoma. The posterior thigh soft tissue mass was surgically resected with femur bone grafting. Recurrence of schwannoma should be considered but its malignant transformation is exceedingly rare and this can be discounted (3).

description: The Rational Unified Process (RUP) is used broadly by software developers. This technical report fits the Carnegie Mellon Software Engineering Institute's (SEI's) architecture-centric methods into the framework of the RUP. These methods include the Architecture Tradeoff Analysis Method, the SEI Quality Attribute Workshop, the SEI Attribute-Driven Design method, the SEI Cost Benefit Analysis Method, and SEI Active Reviews for Intermediate Design. Since the key process milestone of the Elaboration Phase of the RUP is a completed architecture, the architecture-centric methods appear early in the process during the first two phases (i.e., Inception and Elaboration). This report presents a summary of the RUP and then examines the potential uses of the SEI's architecture-centric methods.

description: The goal of this paper is to understand the persuasive technologies used for smart sport training by runners. The Persuasive Systems Design (PSD) by Oinas-Kukkonen & Harjumaa (2009) was used as the framework, and its components were identified. This takes in consideration the analysis of the persuasion context (intent, event, strategy), design of system qualities, and intended behaviour changes. This work explores and consolidates findings from 35 works. It provides different perspectives from this multidisciplinary field such as psychology, technology, social sciences, sport sciences, etc. The hope is that this framework will help advance the understanding of persuasive technologies design for smart sport training for runners.

description: The ouflowing proper motions of fifteen knots in the dominant northwestern lobe of the high-excitation poly-polar planetary nebula NGC 6302 have been determined by comparing their positions relative to those of faint stars in an image taken at the San Pedro Martir Observatory in 2007 to those in a South African Astronomical Observatory archival plate obtained by Evans in 1956. The Hubble-type expansion of this lobe is now directly confirmed in a model independent way from these measurements. Furthermore, an unambiguous distance to NGC 6302 of 1.17 +/- 0.14 kpc is now determined. Also all the velocity vectors of the fifteen knots (and two others) point back to the central source. An eruptive event from within the central torus, approximately 2200 years previously must have created the high speed lobes of NGC 6302.

description: The search for strong topological phases in generic aperiodic materials and meta-materials is now vigorously pursued by the condensed matter physics community. In this work, we first introduce the concept of patterned resonators as a unifying theoretical framework for topological electronic, photonic, phononic etc. (aperiodic) systems. We then discuss, in physical terms, the philosophy behind an operator theoretic analysis used to systematize such systems. A model calculation of the Hall conductance of a 2-dimensional amorphous lattice is given, where we present numerical evidence of its quantization in the mobility gap regime. Motivated by such facts, we then present the main result of our work, which is the extension of the Chern number formulas to Hamiltonians associated to lattices without a canonical labeling of the sites, together with index theorems that assure the quantization and stability of these Chern numbers in the mobility gap regime. Our results cover a broad range of applications, in particular, those involving quasi-crystalline, amorphous as well as synthetic (i.e. algorithmically generated) lattices.

Fano resonances in plasmonic heptamer nano-hole arrays
Creators: name: Hajebifard, Akram
name: Berini, Pierre
Publisher: name: My University
Year: 2017

description: The optical properties of gold heptamer nanohole arrays have been investigated theoretically and numerically. This structure support pronounced Fano resonances with high transmittance (~50%) and narrow bandwidths (down to 12 nm). The Fano features arise from the interference between light directly transmitted through the holes, and light indirectly scattered through the excitation of localized surface plasmon polaritons (LSPPs), propagating surface plasmon polaritons (SPPs), or/and waves related to Wood's anomaly (WA). The mechanisms behind the generation of these resonances are revealed by observing near-field distributions, altering the structural parameters and applying the Bloch wave model. Furthermore, it is shown that Fano resonances associated with LSPPs exhibit high surface (2 nm/nm) and bulk sensitivities (400 nm/RIU). However, the highest figure of merit (~24 RIU-1) occurs for a Fano resonance involving a WA and SPP mode.

Publisher: name: Washington State University
Year: 2007
Subjects: Algorithms

description: Eigenvalues of unitary matrices arise in a variety of contexts in applied mathematics. This dissertation present four new algorithms for computing the eigenvalues of unitary matrices. In chapter 1, we give an overview these algorithms, and then survey the major applications where eigenvalues of unitary matrices arise. In chapter 2, we present the unitary QR algorithm, an algorithm that can used to compute all of the eigenvalues of a unitary matrix. In chapter 3, we present two Krylov space algorithms that approximate some of the eigenvalues of a large unitary matrix. Finally, in chapter 4, we present an algorithm that compute the eigenvalues of a unitary matrix U when U is expressed as a product U = U1 Un of unitary matrices of the same order. As a special case, we consider the generalized eigenvalue problem for unitary matrices.

description: This study deals with the development of novel fire-retardant formulations to reduce the flammability of a low density rigid insulation panel made from hemp shiv glued with a thermosetting bio-binder. The objective is to identify possible substitutes to conventional fire-retardants, which are free from ammonium salts or boron compounds. The effect of the different treatments on the thermal decomposition of hemp shiv was analyzed by TGA/DA. The fire reaction of the insulation panel made of treated hemp shiv and bio-binder was characterized using the standardized cone calorimeter test. Two conventional treatments are used as references: a commercial ammonium phosphate/sulfate flame-retardant and a commonly used flame-retardant composition based on boric acid. Results showed that magnesium sulfate heptahydrate, phosphoric acid, sulfuric acid, functionalized silica particles and a combination of these could provide better fire retardancy effect than the conventional treatment based on boric acid. However, some treatments were not compatible with the selected panel formulation because they hindered the thermosetting binder polymerization leading to poor mechanical properties.

Two Higgs Models for Large Tan Beta and Heavy Second Higgs
Creators: name: Randall, Lisa
Publisher: name: arXiv
Year: 2007
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We study two Higgs models for large $\tanβ$ and relatively large second Higgs mass. In this limit the second heavy Higgs should have small vev and therefore couples only weakly to two gauge bosons. Furthermore, the couplings to down type quarks can be significantly modified (so long as the second Higgs is not overly heavy). Both these facts have significant implications for search strategies at the LHC and ILC. We show how an effective theory and explicit fundamental two Higgs model approach are related and consider the additional constraints in the presence of supersymmetry or $Z_2$ flavor symmetries. We argue that the best tests of the two Higgs doublet potential are likely to be measurements of the light Higgs branching fractions. We show how higher dimension operators that have recently been suggested to raise the light Higgs mass are probably best measured and distinguished in this way.

Integrating 001 Tool Support into the Feature-Oriented Domain Analysis Methodology
Creators: name: Krut, Robert
Publisher: name: Carnegie Mellon University

Subjects: subject: 80309 Software Engineering
subject: FOS: Computer and information sciences

description: This report addresses the need for additional tool support for the Feature-Oriented Domain Analysis (FODA) methodology, developed at the Software Engineering Institute (SEI). Previous FODA studies relied on multiple tools to represent the components of a domain model. This report discusses the ability to represent an analyzed domain within the confines of a single support tool. This discussion was based on the transformation of a recently completed domain analysis from a multi-tool, multi-view representation into a single tool which represents the multiple views of a FODA domain model. This report also describes the potential for prototyping of systems using the FODA domain analysis products and the supporting tool.
Clustering, grouping, and process over networks

description: During the last few years there has been a rapid development in computer networks, especially wireless
description: networks which enable mobile applications. Because of the increasing number of devices involved in
description: network applications, it is necessary to investigate approaches to organize those devices based on their
description: application requirements and make them perform the given tasks. The essential functionalities of a
description: computer network is to establish relationships among network nodes, which are called grouping. An initial form of grouping, called clustering, has been observed by researchers whose research goals are to provide a network architecture that can be used to improve the network performance. In this dissertation, we first propose a number of clustering techniques including SMC, BAC, DCC, and TC, which, in some cases, outperform the existing ones. A more sophisticated form of grouping, in contrast to clustering, is to build relationships among network nodes based on the nodes’ functionalities. To do this, we first propose a specification language, called NetSpec, for studying this more general form of grouping. Using NetSpec, users can describe the desired functionalities of an individual network node, how a subset of nodes, called a group or a bond, are logically connected between each other, and, finally, how such groups evolve. For a network application specified in NetSpec, a compiler is described to translate the specification into a program that will run over a network virtual machine. In the dissertation, we describe the instruction set to support the virtual machine that runs above a physical network. The instruction set is powerful enough to execute the upper layer NetSpec specification while it is simple enough to be efficiently implemented by network protocols running on the under layer physical network. To thread instructions in the instruction set into an execution of the NetSpec specification, we also describe how to implement a non-deterministic scheduler to address fairness, synchronization, group communication control, and concurrency control. Essentially, NetSpec specifies how groups of network nodes evolve. Looking from the angle of each individual node, such an evolution can be characterize as a thread of atomic transitions, each of which is local; e.g., involving two network nodes. Inspired by this view, in the last part of this dissertation, we propose a form of network processes and study, theoretically, its computability and realization on a physical network.
Dismantling Global Binaries of Gender and Sex: Peace Corps, lgbti volunteers, and the pursuit of inclusive development around the world
Creators: name: Leclair, Stephanie
Publisher: name: My University
Year: 2017

description: Around the world, many people experience discrimination and violence because of their real or perceived sexual orientation and/or gender identity. The global development community has recently made clear that the pursuit of inclusive development must be bolder in incorporating lgbti-related concerns. This research presents a case study of how one particular global development organization, Peace Corps, is navigating the complexities of sexual orientation, gender identity, and development in the context of international volunteer cooperation. Through a content analysis of select Peace Corps’ texts, this research seeks to better understand how staff and volunteers at the organization are overcoming the obstacles to queering development, while also navigating personal safety and security concerns. Results indicate that lgbti-inclusion is formally focused on diversity in recruitment and informally spearheaded by individual efforts of the selected Peace Corps volunteers. It has not yet been mainstreamed across broader programming objectives and activities. Nevertheless, the findings indicate that through these efforts, Peace Corps has established a solid foundation upon which to build greater inclusion of lgbti people more broadly in the pursuit of world peace, friendship, and improved cross-cultural understanding around the world.

description: We exhibit an explicit natural isomorphism between spaces of branched and geometric rough paths. This provides a multi-level generalisation of the isomorphism of Lejay-Victoir (2006) as well as a canonical version of the Itô-Stratonovich correction formula of Hairer-Kelly (2015). Our construction is elementary and uses the property that the Grossman-Larson algebra is isomorphic to a tensor algebra. We apply this isomorphism to study signatures of branched rough paths. Namely, we show that the signature of a branched rough path is trivial if and only if the path is tree-like, and construct a non-commutative Fourier transform for probability measures on signatures of branched rough paths. We use the latter to provide sufficient conditions for a random signature to be determined by its expected value, thus giving an answer to the uniqueness moment problem for branched rough paths.

Bulk Heating Effects as Tests for Collapse Models

Year: 2018

subject: FOS: Physical sciences

description: We discuss limits on the noise strength parameter in mass-proportional-coupled wave function collapse models implied by bulk heating effects, and examine the role of the noise power spectrum in comparing experiments of different types. This comparison utilizes a calculation of the rate of heating through phonon excitation implied by a general noise power spectrum $λ(ω)$. We find that in the standard heating formula, the reduction rate $λ$ is replaced by $λ_{\rm eff}=\frac{2}{3 π^{3/2}} \int d^3w e^{-\vec w^2} \vec w^2 λ(ω_L(\vec w/r_c))$, with $ω_L(\vec q)$ the longitudinal acoustic phonon frequency as a function of wave number $\vec q$, and with $r_C$ the noise correlation length. Hence if the noise power spectrum is cut off below $ω_L(|\vec q| \sim r_c^{-1})$, the bulk heating rate is sharply reduced, allowing compatibility of current experimental results. We suggest possible new bulk heating experiments that can be performed subject to limits placed by natural heating from radioactivity and cosmic rays. The proposed experiments exploit the vanishing of thermal transport in the low temperature limit.

Publisher: name: arXiv

description: We present three-dimensional, self-consistent radiative transfer solutions with a new Monte Carlo radiative equilibrium code. The code, RADISHE ($\bf{RAD}$iative transfer $\bf{I}$n $\bf{S}$moothed particle $\bf{H}$ydrodynamics and $\bf{E}$ulerian codes), can be applied to calculate the emergent spectral energy distributions (SEDs) and broadband images from optical to millimeter wavelengths of arbitrary density geometries with distributed sources of radiation. One of the primary uses of this code has been to interface with hydrodynamical codes to calculate emergent SEDs along a simulation time sequence. The primary methodological focus of this paper is on the radiative equilibrium temperature calculation. We find that an iterative calculation of the temperature, which takes as the Monte Carlo estimator for the mean free intensity the sum of photon flight paths, is significantly faster than relaxation temperature calculation methods, particularly when large numbers of grid cells are required, i.e., in modeling three-dimensional geometries such as the dust envelopes of turbulent massive protostellar cores or infrared bright galaxies. We present simulated color-color plots for infrared bright galaxies at a range of redshifts, and unfold these plots as color vs the fractional AGN luminosity, to demonstrate that $\it{Herschel}$ will be able to effectively discriminate between submillimeter galaxies where the energy source is dominated by AGN and those where star formation dominates.

description: We present a six-dimensional potential energy surface for the H2-H2 dimer based on ab initio electronic structure calculations. The surface is intended to describe accurately the bound and quasibound states of the dimers H2-H2, D2-D2, and H2-D2 that correlate with H2 or D2 monomers in the rovibrational levels (v, j) = (0, 0), (0, 2), (1, 0), and (1, 2). We use four experimentally measured transition energies for these dimers to make two empirical adjustments to the ab initio surface; the adjusted surface gives computed transition energies for 56 experimentally observed transitions that agree with experiment to within 0.036 cm^{-1}. For 29 of the 56 transitions, the agreement between the computed and measured transition energies is within the quoted experimental uncertainty. We use our potential energy surface to predict the energies of another 34 not-yet-observed infrared and Raman transitions for the three dimers.

description: In today's business and operational environments, multiple organizations routinely work collaboratively to acquire, develop, deploy, and maintain technical capabilities via a set of interdependent, networked systems. Measurement in these distributed management environments can be an extremely challenging problem. The CERT Program, part of Carnegie Mellon University's Software Engineering Institute (SEI), is developing the Integrated Measurement and Analysis Framework (IMAF) to enable effective measurement in distributed environments, including acquisition programs, supply chains, and systems of systems. The IMAF defines an approach that integrates subjective and objective data from multiple sources (targeted analysis, reports, and tactical measurement) and provides decision makers with a consolidated view of current conditions. This report is the first in a series that addresses how to measure software security in complex environments. It poses several research questions and hypotheses and presents a foundational set of measurement concepts. It also describes how meaningful measures provide the information that decision makers need when they need it and in the right form. Finally, this report provides a conceptual overview of the IMAF, describes methods for qualitatively and quantitatively collecting data to inform the framework, and suggests how to use the IMAF to derive meaningful measures for analyzing software security performance.

The Effect of Transportation Hubs in the Canadian Economic Context
Creators: name: Fournier, Elisabeth
Publisher: name: My University
Year: 2017

description: This paper analyzes the effect of transportation hubs on economic centrality and four economic and social welfare variables. To do so, we construct the economic centrality variable using a weighted-network approach. We then study its determinants, focusing on whether transportation hubs have an impact on the economic integration of a province. We infer that transportation hubs do have a positive effect on economic centrality. These determinants are then implemented in the analysis of gross domestic product (GDP) per capita, life expectancy, share of the labor force with a secondary education, and infant mortality rate. Our results show that life expectancy and share of the labor force with a secondary education are both positively affected by transportation hubs. On the other hand, we discover that not all methods of transportation have a positive impact on GDP per capita. Lastly, we find that some, but not all, of the determinants of economic centrality explain infant mortality rates.

description: The Lévy-stable distribution is the attractor of distributions which hold power laws with infinite variance. This distribution has been used in a variety of research areas, for example in economics it is used to model financial market fluctuations and in statistical mechanics as a numerical solution of fractional kinetic equations of anomalous transport. This function does not have an explicit expression and no uniform solution has been proposed yet. This paper presents a uniform analytical approximation for the Lévy-stable distribution based on matching power series expansions. For this solution, the trans-stable function is defined as an auxiliary function which removes the numerical issues of the calculations of the Lévy-stable. Then, the uniform solution is proposed as a result of an asymptotic matching between two types of approximations called "the inner solution" and "the outer solution". Finally, the results of analytical approximation are compared to the numerical results of the Lévy-stable distribution function, making this uniform solution valid to be applied as an analytical approximation.

description: Las vidas campesinas se han visto históricamente en desventaja en la comercialización de los alimentos que cultivan. Esto se ha suscitado a causa de la intermediación y las largas cadenas de comercialización como la forma predominante para la venta y abastecimiento de alimentos para las ciudades. Lo anterior ha sido motivación para que desde el Colectivo Puente de la Universidad Externado de Colombia y la Finca Agroecológica Santa Juana (FASJ) en Arcabuco-Boyacá se consoliden iniciativas en torno a los circuitos cortos agroalimentarios como El Convite Campesino que conecta directamente a los campesinos productores de alimentos orgánicos con consumidores en ciudades como Tunja y Bogotá. La presente investigación tiene como objetivo comprender a través de la descripción etnográfica, los elementos que configuran las resistencias a la mecanización de la vida desde el alimento, analizando la relación entre circuitos cortos agroalimentarios, economías solidarias campo – ciudad y la reproducción de la vida campesina. Finalmente, se proponen algunas recomendaciones para potenciar los alcances de los circuitos cortos agroalimentarios.

The objective of this research is to understand, through ethnographic description, the elements that make up the resistance to the mechanization of life from food, analysing the relationship between short agri-food circuits, rural-city solidarity economies and the reproduction of rural life. Finally, a few recommendations are proposed to enhance the scope of short agri-food circuits.

description: Market responses to unpredictable events such as preference change, food contamination, or changes in technology and information are not always known. Phase space reconstruction, a tool designed to analyze nonlinear time series, is investigated for use as an econometric tool to detect nonlinear dynamics economic time series. It is applied to examine consumer responses to unpredictable events, changes in dynamic livestock cycles, and nonlinear structure in regression residuals. The empirical application of phase space reconstruction analyzing economic behavior demonstrates an intuitive, appealing, and straightforward demonstration as to the use of this diagnostic tool. The first essay investigates how to reconstruct dynamic consumer reactions from market events using phase space reconstruction. This approach can provide important and unique empirical insights into consumer reactions to product recall or contaminant events. We apply phase space reconstruction analysis to U.S. meat demand, demonstrating distinct differences between intertemporal shorter run impacts from food safety incidents (e.g., E. Coli and BSE) relative to longer run health effects (e.g., cholesterol). Moreover, we show that consumers have reacted to food safety events differently depending on the particular food contaminate associated with that event. In the second essay, phase space reconstruction is investigated as a diagnostic tool for determining the structure of detected nonlinear processes in regression residuals. Empirical evidence supporting this approach is provided using simulations from an Ikeda mapping and the S&P 500. Results in the form of phase portraits (e.g., scatter plots of reconstructed dynamical systems) provide qualitative information to discern structural components from apparent randomness and provide insights categorizing structural components into functional classes to enhance econometric/time series modeling efforts. The third essay applies the technique of phase space reconstruction to investigate U.S. livestock cycles. Results are presented for both pork and cattle cycles, providing empirical evidence that the cycles themselves have slowly diminished. By comparing the two livestock cycles important insights can be made. The phase space analysis suggests that the biological constraint has become a less significant factor in livestock cycles while technology and information are relatively more significant.

description: Purpose: We introduce a new approach to developmental reflection in which the focus is on differences in how people reflect. When reflecting on challenging experiences, people achieve better development when they tend to look for causes of what happened within changeable personal characteristics and they subsequently focus on improvement of those personal characteristics. Design/Methodology/Approach: Supervisors and subordinates with leadership responsibilities in diverse jobs in varied industries provided survey data (444 individuals in a psychometric testing sample, and 419 paired subordinate/supervisor dyads in a model-testing sample). Findings: The reflection difference construct had the expected factor structure, reliability, and was distinguishable from eight conceptually related variables in the literature. Reflection differences were predicted by theoretically-relevant job, person, and situational variables and were associated with development and performance outcomes. Research limitations/implications: Practical implications: The reflection construct might be used for prediction to identify which individuals are likely to get the most from challenging experiences and improve. Further, by identifying predictors of reflection, ideas for enhancing reflection are provided. Also, by uncovering specific underlying dimensionality of reflection, this offers specific targets for interventions beyond generally encouraging people to reflect. Social implications: Originality/value: This study establishes support for: a) the new theoretical framing of reflection differences, b) a new preliminary model of antecedents and outcomes, and c) an initial scale for future research and practice that can be more explicit about understanding and addressing underlying differences in how people reflect.

description: Advances in construction technology increased the importance of sustainability and reinforce the use of biological admixtures. Using bio-based admixtures brings new horizons to the construction material science by improving concrete properties through a more environmentally friendly and cost-efficient approach. Generally, bio-based additives are used as viscosity modifyin agents (VMAs) in concrete mixes. Traditional bio-based VMAs are water-soluble bipolymers that can be produced from polysaccharide-based biopolymers obtained from cellulose, starch or bacterial fermentation. Through the literature, nopal mucilage, brown algae and bacterial cell walls were proposed as alternatives to these bio-based admixtures. However, these alternatives also require extra processing which results again with a higher unit cost compared to admixtures that could be directly obtained from nature, like the direct addition of cells. The aim of this study is to improve the rheology of cement paste by incorporating Peanibacillus polymxa (P.polymxa) cells and biofilm collected from Bacillus amyloliquefaciens (EPI 60) as viscosity modifying agents (VMAs). To achieve this goal, the bacterial cells and biofilms were directly incorporated into the mix water and influence of cells on viscosity and yield strength was evaluated by rheological tests. The impact of fly ash and superplasticizer on performance of cells were also investigated. Our results showed that the apparent viscosity and yield stress of the cement-paste mix were increased with the addition of the bio-based additives. Biofilm obtained from EPI 60 cells were found to be more efficient in terms of improving rheological parameters. Moreover, both biological VMAs was found to be compatible with the use of fly ash and superplasticizers.

description: The Acquisition Support Program at the Carnegie Mellon Software Engineering Institute assists organizations that develop Department of Defense hardware/software hybrid systems by participating in technical reviews and other validation activities. During recent customer engagements, it has been noted that some development teams do not demonstrate a consistent understanding of integrated diagnostic system needs. In particular, software engineers seem to lack the experience needed in this area. Since software engineers frequently derive the low-level requirements for developing diagnostic systems, a lack of knowledge about deployed testing environments can have significant impact. Failure to adequately address the integrated testing needs of a system profoundly impacts its supportability and, consequently, the cost of that system throughout its life cycle. This report attempts to fill in these gaps in knowledge and experience by presenting an overview of the operational diagnostic life cycle of a system. In addition, it outlines how a system's operational profile impacts diagnostic tradeoffs.

description: We study the correlation between the radio, mid-infrared and far-infrared properties for a sample of 28 blue compact dwarf (BCD) and low metallicity star-forming galaxies observed by Spitzer. We find that these sources extend the same far-infrared to radio correlation typical of star forming late type alaxies to lower luminosities. In BCDs, the 24um (or 22um) mid-infrared to radio correlation is similar to starburst galaxies, though there is somewhat larger dispersion in their q_24 parameter compared to their q_FIR. No strong correlations between the q parameter and galaxy metallicity or effective dust temperature have been detected, though there is a hint of decreasing q_24 at low metallicities. The two lowest metallicity dwarfs in our sample, IZw18 and SBS0335-052E, despite their similar chemical abundance, deviate from the average q$_{24}$ ratio in opposite manners, displaying an apparent radio excess and dust excess respectively.
