description: We present the morphological analysis based on HST-NIC2 (0.075 arcsec/pixel) images in the F160W filter of a sample of 9 massive field (> 10^{11} M_\odot) galaxies spectroscopically classified as early-types at 1.2 within R_e of our galaxies and we compared them with those of early-types at lower redshifts. We find that the surface brightness of our galaxies should get fainter by 2.5 mag from z~1.5 to z~0 to match the surface brightness of the local ellipticals with comparable R_e, i.e. the local Kormendy relation. Luminosity evolution without morphological changes can only explain half of this effect, as the maximum dimming expected for an elliptical galaxy is ~1.6 mag in this redshift range. Thus, other parameters, possibly structural, may undergo evolution and play an important role in reconciling models and observations. Hypothesizing an evolution of the effective radius of galaxies we find that R_e should increase by a factor 1.5 from z~1.5 to z~0.

description: The purpose of this communication is to discuss the simulation of a free surface compressible flow between two fluids, typically air and water. We use a two fluid model with the same velocity, pressure and temperature for both phases. In such a numerical model, the free surface becomes a thin three dimensional zone. The present method has at least three advantages: (i) the free-surface treatment is completely implicit; (ii) it can naturally handle wave breaking and other topological changes in the flow; (iii) one can easily vary the Equation of States (EOS) of each fluid (in principle, one can even consider tabulated EOS). Moreover, our model is unconditionally hyperbolic for reasonable EOS.

description: We present the first evaluation of a recently developed silicon-strip detector for photon-counting dual-energy breast tomosynthesis. The detector is well suited for tomosynthesis with high dose efficiency and intrinsic scatter rejection. A method was developed for measuring the spatial resolution of a system based on the detector in terms of the three-dimensional modulation transfer function (MTF). The measurements agreed well with theoretical expectations, and it was seen that depth resolution was won at the cost of a slightly decreased lateral resolution. This may be a justifiable trade-off as clinical images acquired with the system indicate improved conspicuity of breast lesions. The photon-counting detector enables dual-energy subtraction imaging with electronic spectrumsplitting. This improved the detectability of iodine in phantom measurements, and the detector was found to be stable over typical clinical acquisition times. A model of the energy resolution showed that further improvements are within reach by optimization of the detector.
Extragalactic Globular Clusters and Galaxy Formation

description: Globular cluster (GC) systems have now been studied in galaxies ranging from dwarfs to giants and spanning the full Hubble sequence of morphological types. Imaging and spectroscopy with the Hubble Space Telescope and large ground-based telescopes have together established that most galaxies have bimodal color distributions that reflect two subpopulations of old GCs: metal-poor and metal-rich. The characteristics of both subpopulations are correlated with those of their parent galaxies. We argue that metal-poor GCs formed in low-mass dark matter halos in the early universe and that their properties reflect biased galaxy assembly. The metal-rich GCs were born in the subsequent dissipational buildup of their parent galaxies and their ages and abundances indicate that most massive early-type galaxies formed the bulk of their stars at early times. Detailed studies of both subpopulations offer some of the strongest constraints on hierarchical galaxy formation that can be obtained in the near-field.

he role of lipoprotein-X in the development of glomerulosclerosis in familial LCAT deficienty
Creators: name: Lynn, Edward G.
Publisher: name: University of British Columbia
Year: 2009

description: Progressive glomerulosclerosis is a major complication in patients with familial lecithin:cholesterol acyltransferase (LCAT) deficiency. The absence of active LCAT in the plasma of these patients leads to the formation of an abnormal plasma lipoprotein, lipoprotein-X (Lp-X). Renal biopsies of these patients have revealed lipid deposition, macrophage infiltration, the presence of foam cells, and mesangial cell proliferation in affected glomeruli. The objective of this project was to examine the role of Lp-X in the development of glomerulosclerosis. Our results have demonstrated that Lp-X is taken up by cultured rat mesangial cells and that the lipid component of Lp-X is metabolized intracellularly. We have also investigated the role of apolipoproteins in the uptake of Lp-X. Both apo C-l and 0-1II inhibited Lp-X uptake while C-ll (1.5 fold) and E (4 fold), as well as all four apolipoproteins combined (1.5 fold), stimulated this process. We have also observed that cell surface proteoglycans are involved in modulating the uptake of this abnormal lipoprotein. Lp-X, either alone or combined with rat peritoneal macrophages, has no effect of the proliferation of mesangial cells.

description: It is a conventional wisdom that the helical edge states of quantum spin Hall (QSH) insulator are particularly stable due to the topological protection of time-reversal symmetry. Here, we report the first experimental observation of an edge-dependent quantum (pseudo-)spin Hall effect by employing two Kekule electric circuits with molecule-zigzag and partially-bearded edges, where the chirality of the circulating current in the unit cell mimics the electron spin. We observe a helicity flipping of the topological in-gap modes emerging in opposite parameter regions for the two edge geometries. Experimental findings are interpreted in terms of the mirror winding number defined in the unit cell, the choice of which exclusively depends on the edge shape. Our work offers a deeper understanding of the boundary effect on the QSH phase, and pave the way for studying the spin-dependent topological physics in electric circuits.

Evaluation of the ET2000 Guardrail End Treatment

Subjects: subject: Transportation Engineering

description: The objective of this study was to report the results of the monitoring of the performance of the ET2000 guardrail end treatment in traffic crashes. This end treatment has an energy absorbing design in which a vehicle will push a guardrail extruder back as posts designed to breakaway are broken. The W-beam guardrail is flattened as it goes through the extruder and exits a slot away from traffic.  Data for a total of 135 collisions involving the ET 2000 were identified. A crash report was obtained in the majority of crashes and the damaged guardrail was inspected in almost all cases. The involved vehicle was inspected when available. Proper or improper performance of end treatments in the collisions were judged, when a police report was available, based on whether it performed as designed.  Field performance of the ET2000, as documented in traffic crashes, shows that, considering all the impacts, this end treatment has performed properly. In some instances the end treatment bent, rather than being pushed straight back, during the collision. This could typically be related to the angle at which the impact occurred.  Results warrant continued use of this type of end treatment. However, its cost compared to other end treatments would not justify a widespread use on all types of highways.

description: In this paper, we propose a mild condition, named Condition $(**)$, for collections of sequence of integers and show that for any measure preserving system the Pinsker $σ$-algebra is a characteristic $σ$-algebra for the averages along a collection satisfying Condition $(**)$. We introduce the notion of $Δ$-weakly mixing subsets along a collection of sequences of integers and show that positive topological entropy implies the existence of $Δ$-weakly mixing subsets along a collection of "good" sequences. As a consequence, we show that positive topological entropy implies multi-variant Li-Yorke chaos along polynomial times of the shift prime numbers.
Evaluation of Kentucky’s “Buckle Up Kentucky: It’s the Law and It’s Enforced” 2004 Campaign

description: The objective of this report was to document the results of the “Buckle Up Kentucky: It’s the Law & It’s Enforced” 2004 campaign in Kentucky. The campaign involved a combination of earned media, paid media, and enforcement. The earned media started two weeks prior to Memorial Day 2004 and continued through the enforcement period. The paid media started one week prior to Memorial Day. The enforcement period was a two-week period including the week before and the week of Memorial Day.  The evaluation of the campaign included documenting the activities associated with the program (publicity and enforcement) and evaluating the results. The evaluation involved conducting observations of seat belt usage at a sample of locations across the state, documenting the enforcement activities, and comparing the number of fatal and injury crashes during the enforcement period with previous years.  Seat belt usage at a mini-sample set of 21 locations across the state (compared to 200 sites for a full statewide survey) found that usage increased from a baseline level of 64.5 percent to a high of 70.5 percent during the enforcement phase of the campaign. No substantial difference in usage rates could be associated with only the media portion of the campaign with usage rates of 64.5 and 65.4 percent during the earned and paid media, respectively.  Enforcement was conducted by both state and local police through saturated enforcement and checkpoints. A total of 6,587 seat belt citations and 429 child restraint citations were given during the two-week enforcement period.  The numbers of injury crashes and injuries during the two-week enforcement period of the campaign were lower than in any of the previous three years. The number of injuries during this period was 235 less than the average of the previous three years.  A review of the data results in the opinion that the current law in Kentucky must be changed from secondary to primary enforcement to obtain a long-term high seat belt use percentage. There must also be an awareness by the public that the law is being enforced.

description: We report on the detection in Sloan Digital Sky Survey data of a 45 degree tidal stream of stars, extending from Bootes to Ursa Major, which we associate with the halo globular cluster NGC 5466. Using an optimal contrast, matched filter technique, we find a long, almost linear stellar stream with an average width of 1.4 degrees. The stream is an order of magnitude more tenuous than the stream associated with Palomar 5. The stream's orientation on the sky is consistent to a greater or lesser extent with existing proper motion measurements for the cluster.

title: Contemporary Chilean Cinema: Film Practices and Narratives of National Cinema within the Chilean ‘Film Community’
Creators: name: Peirano, María Paz
Publisher: name: University of Kent
Year: 2015

description: This thesis presents an anthropological perspective on the film production practices and narratives underlying the construction of contemporary Chilean national cinema. Based on a multi-sited ‘travelling’ ethnography, it reflects on small, peripheral film production in a transnational neoliberal context, where ‘local’ and ‘global’ trends converge, and focuses on the case of Chilean cinema, which has expanded its production, global circulation and exhibition. The research is grounded in the film experiences of the Chilean film community, a network of film professionals (filmmakers, critics, exhibitors and other film agents) involved in the construction of national cinema. The thesis provides a contextually-based perspective on national film, which is uncommon in both Anthropology and Film Studies, seeking to expand the still emerging field of anthropology of cinema. More than as a group of ‘national’ films, Chilean cinema is understood as both an art world and a field of cultural production, arguing that ‘national cinema’ is both a cultural artifact and a social practice, which is constructed in permanent negotiations between Chilean professionals and other agents in the field. The thesis claims that the film experience of Chilean professionals is part of a broader experience of globalisation, and discusses the formation of artistic, professional and national subjectivities in the neoliberal context, where the identity of Chilean ‘national’ cinema is often contested. It then deconstructs the idea of national cinema as a bounded cultural product, highlighting the overlapping social and cultural traits that affect Chileans’ creative processes. The thesis examines the ways in which Chilean professionals have made sense of this transnational context, reshaping both their social performances and their cinematographic imagination. By referring to the case of Chilean cinema, the thesis shows the complexities of building a contemporary peripheral film industry. It discusses the construction of national communities, cultural commodification, precarious global labour conditions, and the role of national and international social networks in media production. It argues that Chilean cinema practices, particularly at international film festivals, evince overlapping narratives of art and business as well as localism and cosmopolitanism, revealing some of the cultural paradoxes of local film production.

description: We consider some aspects of counting BPS operators which are annihilated by two supercharges, in superconformal field theories. For non-zero coupling, the corresponding multi-variable partition functions can be written in terms of generating functions for vector partitions or their weighted generalisations. We derive asymptotics for the density of states for a wide class of such multi-variable partition functions. We also point out a particular factorisation property of the finite N partition functions. Finally, we discuss the concept of a limit curve arising from the large N partition functions, which is related to the notion of a typical state and discuss some implications for the holographic duals.

description: The La-based '214' cuprates host several symmetry breaking phases including superconductivity, charge and spin order in the form of stripes, and a structural othorhombic-to-tetragonal phase transition. Therefore, these materials are an ideal system to study the effects of uniaxial stress onto the various correlations that pervade the cuprate phase diagram. We report resonant x-ray scattering experiments on $\textrm{La}_{1.475}\textrm{Nd}_{0.4}\textrm{Sr}_{0.125}\textrm{Cu}\textrm{O}_{4}$ (LNSCO-125) that reveal a significant response of charge stripes to uniaxial tensile-stress of $\sim$ 0.1 GPa. These effects include a reduction of the onset temperature of stripes by $\sim$ 50 K, a 29 K reduction of the low-temperature orthorhombic-to-tetragonal transition, competition between charge order and superconductivity, and a preference for stripes to form along the direction of applied stress. Altogether, we observe a dramatic response of the electronic properties of LNSCO-125 to a modest amount of uniaxial stress.

2004 Safety Belt Usage Survey in Kentucky

Year: 2004
Subjects: subject: Transportation Engineering

description: The objective of this study was to establish 2004 safety belt and child safety seat usage rates in Kentucky. The 2004 survey continues to document the results after enactment of a statewide mandatory safety belt law in 1994 and safety belt enforcement campaign. Data were collected at 200 randomly selected sites spread across Kentucky. Data from the individual sites were combined into a statewide percentage considering roadway functional classification, geographic region, and vehicle miles traveled.  The data show that the usage rate in 2004 (66.0 percent) was slightly higher than that in 2003 (65.5 percent). This compared to 62.0 percent in 2002, 61.9 percent in 2001, 60 percent in 2000, 59 percent in 1999, 54 percent in 1998, 1997 and 1995, 55 percent in 1996, and 58 percent in 1994. The current usage is substantially above the 1993 level, prior to enactment of the statewide law, of 42 percent.  The 2004 statewide usage rate for children under the age of four was determined to be 96.0 percent. This continues the high rate found for this age category and compares to the previous high of 94.8 percent in 2003.  The statewide law, except for children, involves secondary enforcement. The very high usage rate for children can be related to primary enforcement and education. To obtain the maximum possible increase in usage for all vehicle occupants, the current law should be modified to allow primary, rather than secondary, enforcement for all vehicle occupants. The potential increase which can result from an emphasis on enforcement was shown by the results obtained during the enforcement period of this year’s “Buckle Up Kentucky: It’s the Law & It’s Enforced” campaign. As a minimum, primary enforcement should apply to drivers while they are in the permit and intermediate phase of the graduated license program.

This cooling mechanism can lead to very large heat fluxes per channel up to 10^4 times greater than currently achieved with superconducting tunnel junctions. This efficacy and its availability in a two-dimensional electron system make this method of particular relevance for the implementation of quantum nanostructures operating at cryogenic temperatures.

description: This paper describes the consonant inventory and syllable structure in Angaité, a member of the Enlhet-Enenlhet family. Angaité utilizes 14 consonants which are described in this paper: five voiceless stops, three nasals, three fricatives, and three approximants. Two possible analyses of syllable structure are discussed, each of which results in slightly different restrictions on the distribution of glides within syllables as well as the relative frequency of different syllable structures. This paper also briefly sketches what is known of the vowel system in Angaité and how it relates to other suprasegmental features. Finally, this paper situates Angaité in the context of the language family and the broader Chaco region in which it is spoken, and it outlines key areas for future research in Angaité phonology.

description: The Heavy Quark Effective Theory provides a systematic method to estimate a mixing angle of hadron states in a heavy quark, such as the charm quark (c) and the bottom quark (b). By using this method, the mixing angle of the baryons $\varXi_Q-\varXi_Q'$ can be estimated. It is found that the mixing angle between $\varXi_Q$ and $\varXi_Q'$ is given by $θ_b = 4.51^{\circ} \pm 0.79 ^{\circ}$ for $Q = b$ case and $θ_c = 8.12^{\circ} \pm 0.80 ^{\circ}$ for $Q = c$ case.

description: As proved by Hedden and Ording, there exist knots for which the Ozsvath-Szabo and Rasmussen smooth concordance invariants, tau and s, differ. The Hedden-Ording examples have nontrivial Alexander polynomials and are not topologically slice. It is shown in this note that a simple manipulation of the Hedden-Ording examples yields a topologically slice Alexander polynomial one knot for which tau and s differ. Manolescu and Owens have previously found a concordance invariant that is independent of both tau and s on knots of polynomial one, and as a consequence have shown that the smooth concordance group of topologically slice knots contains a summand isomorphic to a free abelian group on two generators. It thus follows quickly from the observation in this note that this concordance group contains a subgroup isomorphic to a free abelian group on three generators.
description: In the first version of this note, the main result was applied to show that the smooth concordance group of topologically slice knots contains a summand isomorphic to a free abelian group on two generators. The author has learned that Manolescu and Owens previously found a knot invariant, based on the Heegaard-Floer Homology of the 2-fold branched cover of the knot, that they used to detect such a summand (see math.GT/0508065). Thus, a consequence of this note is that the work of Hedden-Ording and Manolescu-Owens combines to give a summand that is free on three generators
Photon-counting CT with silicon detectors: feasibility for pediatric imaging

description: X-ray detectors made of crystalline silicon have several advantages including low dark currents, fast charge collection and high energy resolution. For high-energy x-rays, however, silicon suffers from its low atomic number, which might result in low detection efficiency, as well as low energy and spatial resolution due to Compton scattering. We have used a monte-carlo model to investigate the feasibility of a detector for pediatric CT with 30 to 40 mm of silicon using x-ray spectra ranging from 80 to 140 kVp. A detection efficiency of 0.74 was found at 80 kVp, provided the noise threshold could be set low. Scattered photons were efficiently blocked by a thin metal shielding between the detector units, and Compton scattering in the detector could be well separated from photo absorption at 80 kVp. Hence, the detector is feasible at low acceleration voltages, which is also suitable for pediatric imaging. We conclude that silicon detectors may be an alternative to other designs for this special case.

description: In this report I review some aspects of the algebraic structure of QFT related with the doubling of the degrees of freedom of the system under study. I show how such a doubling is related to the characterizing feature of QFT consisting in the existence of infinitely many unitarily inequivalent representations of the canonical (anti-)commutation relations and how this is described by the q-deformed Hopf algebra. I consider several examples, such as the damped harmonic oscillator, the quantum Brownian motion, thermal field theories, squeezed states, classical-to-quantum relation, and show the analogies, or links, among them arising from the common algebraic structure of the q-deformed Hopf algebra.

description: Deep inelastic scattering and its diffractive component, $ep \to e^{\prime}γ^* p \to e^{\prime}XN$, have been studied at HERA with the ZEUS detector using an integrated luminosity of 52.4 pb$^{-1}$. The $M_X$ method has been used to extract the diffractive contribution. A wide range in the centre-of-mass energy $W$ (37 -- 245 GeV), photon virtuality $Q^2$ (20 -- 450 GeV$^2$) and mass $M_X$ (0.28 -- 35 GeV) is covered. The diffractive cross section for $2 < M_X < 15$ GeV rises strongly with $W$, the rise becoming steeper as $Q^2$ increases. The data are also presented in terms of the diffractive structure function, $F^{\rm D(3)}_2$, of the proton. For fixed $Q^2$ and fixed $M_X$, $\xpom F^{\rm D(3)}_2$ shows a strong rise as $\xpom \to 0$, where $\xpom$ is the fraction of the proton momentum carried by the Pomeron. For Bjorken-$x < 1 \cdot 10^{-3}$, $\xpom F^{\rm D(3)}_2$ shows positive $\log Q^2$ scaling violations, while for $x \ge 5 \cdot 10^{-3}$ negative scaling violations are observed. The diffractive structure function is compatible with being leading twist. The data show that Regge factorisation is broken.

Evaluating observing strategies for the Bam cosmic microwave background anisotropy experiment

Publisher: name: University of British Columbia

description: An observing strategy for the Balloon-Borne Anisotropy Measurement (BAM) is chosen by performing simulations on a computer. Several strategies are modeled and the performance is graded by its ability to constrain a parameterized description of the Cosmic Microwave Background (CMB) angular power spectrum. We have chosen a model that is described by a normalization and slope in the area of the power spectrum BAM is sensitive too. We argue that during the next flight of BAM from Palestine Texas, a 20° azimuthal scan centered on the meridian at a declination of 70°, will in six hours of data collection verify anisotropy at scales of a few degrees, and determine whether or not the power spectrum is rising towards an expected Doppler peak at scales of ~ 1°. All of the steps necessary to conduct such an investigation are described in detail. Particular attention is given to developing efficient analysis techniques that make manipulation of the large data sets feasible. This is necessary to conduct Monte-Carlo studies of the instruments' ability to constrain the model parameters. Based on these results, we formulate an objective for the next flight of BAM that includes a detailed measurement of its beam size and shape; these details are necessary to avoid biasing the maximum likelihood fits of the model parameters. Although BAM is chosen as a particular example, the techniques are general enough to be applied to any similar experiment that studies CMB temperature anisotropies.

description: The scale invariant feature transform (SIFT) algorithm is considered a classical feature extraction algorithm within the field of computer vision. SIFT keypoint descriptor matching is a computationally intensive process due to the amount of data consumed. In this work, we designed a novel fully pipelined hardware accelerator architecture for SIFT keypoint descriptor matching. The accelerator core was implemented and tested on a field programmable gate array (FPGA). The proposed hardware architecture is able to properly handle the memory bandwidth necessary for a fully-pipelined implementation and hits the roofline performance model, achieving the potential maximum throughput. The fully pipelined matching architecture was designed based on the consine angle distance method. Our architecture was optimized for 16-bit fixed-point operations and implemented on hardware using a Xilinx Zynq-based FPGA development board. Our proposed architecture shows a noticeable reduction of area resources compared with its counterparts in literature, while maintaining high throughput by alleviating memory bandwidth restrictions. The results show a reduction in consumed device resources of up to 91 percent in LUTs and 79 percent of BRAMs. Our hardware implementation is 15.7 times faster than the comparable software approach.
Association of the B cell antigen receptor with protein chaperones
Creators: name: Foy, Shaun Patrick
Publisher: name: University of British Columbia
Year: 2009

description: The multimeric B cell antigen receptor (BCR) consists of four different receptor subunits: immunoglobulin heavy chain (Igu), light chain (X), Iga and Igp. These four chains must assemble correctly in the endoplasmic reticulum (ER) before the receptor can be transported to the cell surface. Recent evidence in lymphoid cells suggests that during receptor assembly the mlgM part (Igu. + light chain) of the BCR interacts with chaperone proteins in the ER. In this study we have examined the proteimprotein interactions between three chaperones, GRP78 (BiP), GRP94 and calnexin with the wildtype BCR and with a BCR containing an altered u heavy chain. By generating cell lines that express various intermediate assembled forms of the BCR (Igu+A,+Iga+Ig(3, Igu+Ji+Iga, Igu+k, Igu, X, Iga, or Igp), we have been able to identify the protein chaperones associated with each receptor subunit. Our data showed that, when expressed by itself in non-lymphoid cells, Iga associated with GRP94 and that the level of association increased dramatically when other BCR chains were co-expressed. Iga was found associated with BiP and calnexin in lymphoid cells, however we believe these interactions were likely mediated through other BCR chains present. We could find no evidence of Igp interactions with any of the other chaperone proteins tested. Interestingly, our results also showed that, when expressed alone, X light chain associated with calnexin. Consistent with the literature, u heavy chain was found associated with all three protein chaperones tested. Our results are consistent with the model suggesting an ordered and sequential interaction between assembling BCR components and the GRP78 and GRP94 protein chaperones during early stages during receptor assembly. Recent evidence suggesting the membrane spanning region of Igu is particularly important for interacting with protein chaperones led us to examine an altered form of u heavy chain that escapes ER retention in lymphoid cells. We found that this mutant did not escape ER retention in non-lymphoid cells nor did it bind chaperones differently from wildtype. This observations suggests that the presence of B cell specific proteins may mediate the transport of the mutant protein to the cell surface in lymphoid cells.

This metal-poor sample underlies the recently-discovered extended rotating component, and has no detected metallicity gradient. This discovery uses a large sample of 9861 radial velocities of Red Giant Branch (RGB) stars obtained with the Keck-II telescope and DEIMOS spectrograph, with 827 stars with robust radial velocity measurements isolated kinematically to lie in the halo component primarily by windowing out the extended rotating component which dominates the photometric profile of Andromeda out to $

description: In this work, a numerical modal decomposition approach is applied to model the optical field of laser light after propagating through a highly multi-mode fiber. The algorithm for the decomposition is based on the reconstruction of measured intensity profiles along the laser beam caustic with consideration of intermodal degrees of coherence derived from spectral analysis. To enhance the accuracy of the model, different approaches and strategies are applied and discussed. The presented decomposition into a set of LP modes enables both the wave-optical simulation of radiation transport by highly multi-mode fibers and, additionally, the analysis of free-space propagation with arbitrarily modified complex amplitude distributions.

description: Bonazzola, Gourgoulhon, Grandclément, and Novak [Phys. Rev. D {\bf 70}, 104007 (2004)] proposed a new formulation for 3+1 numerical relativity. Einstein equations result, according to that formalism, in a coupled elliptic-hyperbolic system. We have carried out a preliminary analysis of the mathematical structure of that system, in particular focusing on the equations governing the evolution for the deviation of a conformal metric from a flat fiducial one. The choice of a Dirac's gauge for the spatial coordinates guarantees the mathematical characterization of that system as a (strongly) hyperbolic system of conservation laws. In the presence of boundaries, this characterization also depends on the boundary conditions for the shift vector in the elliptic subsystem. This interplay between the hyperbolic and elliptic parts of the complete evolution system is used to assess the prescription of inner boundary conditions for the hyperbolic part when using an excision approach to black hole spacetime evolutions.

description: Spectral imaging is a method in medical x-ray imaging to extract information about the object constituents by the material-specific energy dependence of x-ray attenuation. Contrast-enhanced spectral imaging has been thoroughly investigated, but unenhanced imaging may be more useful because it comes as a bonus to the conventional non-energy-resolved absorption image at screening; there is no additional radiation dose and no need for contrast medium. We have used a previously developed theoretical framework and system model that include quantum and anatomical noise to characterize the performance of a photon-counting spectral mammography system with two energy bins for unenhanced imaging. The theoretical framework was validated with synthesized images. Optimal combination of the energy-resolved images for detecting large unenhanced tumors corresponded closely, but not exactly, to minimization of the anatomical noise, which is commonly referred to as energy subtraction. In that case, an ideal-observer detectability index could be improved close to 50% compared to absorption imaging. Optimization with respect to the signal-to-quantum-noise ratio, commonly referred to as energy weighting, deteriorated detectability. For small microcalcifications or tumors on uniform backgrounds, however, energy subtraction was suboptimal whereas energy weighting provided a minute improvement. The performance was largely independent of beam quality, detector energy resolution, and bin count fraction. It is clear that inclusion of anatomical noise and imaging task in spectral optimization may yield completely different results than an analysis based solely on quantum noise.
