description: Bestimmung des Energiespektrums ultra-hochenergetischer kosmischer Strahlung mit Daten des Pierre-Auger-Observatoriums
Das Thema dieser Arbeit ist die Bestimmung des Energiespektrums kosmischer Strahlung bei höchsten Energien unter Verwendung von Daten des Oberflächendetektors des Pierre-Auger-Observatoriums. Ein wichtiger Beitrag zu den Unsicherheiten der Messung der lateralen Verteilung von Teilchen mit dem Oberflächendetektor ist das fehlende Signal der dem Zentrum des Luftschauers am nächsten liegenden Station. Dieses Problem wird hervorgerufen durch die Sättigung der Auslese-Elektronik und den Übergang zu einem nichtlinearen Verhalten der Photovervielfacher-Antwort. Davon betroffen sind 50% der Ereignisse in dem untersuchten Energiebereich. Eine Methode zur Bestimmung dieses Signal wird entwickelt. Die Abschwächung des Signals in der Atmosphäre wird mittels der Annahme räumlich konstanten Intensität der Kosmischen Strahlung abgeleitet. Besonderer Wert wird auf die Energiekonvertierung vermittels Fluoreszenzdetektor gelegt. Dazu werden Luftschauern Daten verwendet, welche so wohl mit dem Fluoreszenz- als auch mit dem Oberflächen-Detektor gemessen wurden. Um den Effekt der Detektor-Auflösung auf den gemessenen Fluss abzuschätzen, werden realistische Simulationen der Detektorantwort durchgeführt. Die Akzeptanz des Oberflächedetektors ist nur aus Daten bestimmt und die systematischen Unsicherheiten sind mit Hilfe von Simulationen berechnet. Dies ermöglicht eine Erweiterung des Energiespektrums aus Oberflächendetektordaten zu niedrigeren Energien hin, außerhalb des Bereiches voller Trigger-Effizienz. Außer dem durch vertikale Ereignisse des Oberflächendetektors erhaltenen Energiespektrum können zwei weitere unabhängige Spektren bestimmt werden: Ein Hybridspektrum, basierend auf Luftschauern, die den Fluoreszenzdetektor und mindestenz eine Station des Oberflächendetektores getriggert haben, und ein Spektrum mit Oberflächendetektor-Ereignissen mit Zenitwinkeln größer als 60Grad. Diese Spektren werden in einem einzigen Spektrum kombiniert, das sich über den breitesten Energiebereich der aktuellen Daten des Pierre-Auger-Observatoriums erstreckt und dabei die kleinsten Unsicherheiten hat. Das daraus resultierende Spektrum wird in einen astrophysikalischen Kontext gesetzt. Die Fortsetzung des Spektrums oberhalb 40EeV als Potenzgesetz wird mit einer Signifikanz von 5.2σ verworfen. Die Anzahl der erwarteten Ereignisse für ein Potenzgesetz ist 167 ± 3 über 40EeV und 35 ± 1 über 100EeV, wobei die Daten nur je 64 Ereignisse beziehungsweise 1 Ereignis im jeweiligen Bereich enthalten.

description: This study is based on the hypothesis that electromagnetic energy is the actual driving force of the human body, and that what is recorded by brain mapping devices is only the observable part. It is proposed that electricity in the brain is not self-generated but results from the conversion of electromagnetic energy, similar to how photovoltaic cells operate. In this process, photon energy affects electrons within neural bonds, stimulating their movement, which produces measurable electrical current in amperes.

description: Einzelmolekülspektroskopie an Kohlenstoffnanoröhren und deren Herstellung mittels chemischer Gasphasenabscheidung
Im Rahmen dieser Arbeit wurde eine Apparatur zur chemischen Gasphasenabscheidung entwickelt, aufgebaut und dazu verwendet, vertikal und horizontal ausgerichtete Anordnungen aus Kohlenstoffnanoröhren wachsen zu lassen. So hergestellte, einzelne Nanoröhren wurden sowohl mittels eines Photolumineszenzmikroskops (PL Mikroskop), als auch mit Raman-, Rasterkraft- und Rasterelektronenmikroskopie untersucht. Für die Photolumineszenz-Anregungs-Spektroskopie (PLE Spektroskopie) an einwandigen Kohlenstoffnanoröhren (SWNTs) wurde ein PL Lasermikroskop konstruiert, das automatisierte Messungen in einem Anregungswellenlängenbereich von ~600 -1000nm (mittels 3 durchstimmbarer Laser) und die Aufnahme von PL Bildern mit einer räumlichen Auflösung von bis zu 400nm gestattete.
Die PL von direkt gewachsenen, frei hängenden SWNTs wurde mit der von SWNTs in D2O/Tensid Dispersionen und ebenso mit der von SWNTs in organischen Lösungsmitteln verglichen. Die beobachteten Verschiebungen der charakteristischen optischen E11 Emissions- und E22 Anregungsenergien kommen durch Veränderungen in der Umgebung der Nanoröhren zustande. Dadurch ergibt sich eine unterschiedliche dielektrische Abschirmung der elektronischen Anregungen (Exzitonen).
Ebenso wurde die PL von direkt gewachsenen SWNTs (frei hängend und auf der Oberfläche liegend) mit der von einzelnen, aus D2O/Tensid Dispersionen heraus auf einer Oberfläche abgeschiedenen SWNTs bei Temperaturen bis zu 4K verglichen. Nur letztere zeigen bei tiefen Temperaturen PL-Blinken und spektrale Diffusion.
PLE Spektren von frei hängenden SWNTs und von Dispersionen, in denen einzelne Chiralitäten angereichert waren, ermöglichten die erste direkte Beobachtung von zwei tiefliegenden Exzitonenzuständen unterhalb des tiefsten optisch erlaubten E11 Exzitons. Die energetische Position dieser Zustände, sowie deren Intensität im Vergleich zu der E11 Emissionslinie werden diskutiert.
Das PL Mikroskop war empfindlich genug, um die schwache PL von direkt gewachsenen SWNTs auf dielektrischen Oberflächen zu detektieren. Extrem lange, mittels CVD auf Si/SiO2 synthetisierte SWNTs konnten so abgebildet, ihre Chiralität bestimmt und die strukturelle Integrität entlang der Aufrollachse überprüft werden. Darüber hinaus wurden solche Nanoröhren mittels Rasterkraftmikroskopie manipuliert (verschoben, vebogen und zerrissen). Wir zeigen, dass PLE Mikroskopie eine leistungsstarke Methode ist, um noch vorhandene axiale uns torsionale Dehnung in SWNTs nachzuweisen. An gebrochenen Stellen wurde bei Nanoröhren ein auffälliges PL Verhalten gefunden. Schließlich wird ein neues Verfahren vorgestellt, mit dem relative Konzentrationen sowie Quantenausbeuten dispergierter, halbleitender SWNTs durch statistisches Zählen von PL Signalen bestimmt werden können.

description: Homogeneous abundances of light elements, alpha and Fe-group elements from high-resolution FLAMES spectra are presented for 76 red giant stars in M54, a massive globular cluster (GC) lying in the nucleus of the Sagittarius dwarf galaxy. We also derived detailed abundances for 27 red giants belonging to the Sgr nucleus. Our abundances assess the intrinsic metallicity dispersion (~0.19 dex, rms scatter) of M54, with the bulk of stars peaking at [Fe/H]~-1.6 and a long tail extending to higher metallicities, similar to omega Cen. The spread in these probable nuclear star clusters exceeds those of most GCs: these massive clusters are located in a region intermediate between normal GCs and dwarf galaxies. M54 shows the Na-O anticorrelation, typical signature of GCs, which is instead absent in the Sgr nucleus. The light elements (Mg, Al, Si) participating to the high temperature Mg-Al cycle show that the pattern of (anti)correlations produced by proton-capture reactions in H-burning is clearly different between the most metal-rich and most metal-poor components in the two most massive GCs in the Galaxy, confirming early result based on the Na-O anticorrelation. As in omega Cen, stars affected by most extreme processing, i.e. showing the signature of more massive polluters, are those of the metal-rich component. This can be understood if the burst of star formation giving birth to the metal-rich component was delayed by as much as 10-30 Myr with respect to the metal-poor one. The evolution of these massive GCs can be reconciled in the general scenario for the formation of GCs sketched in Carretta et al.(2010a) taking into account that omega Cen could have already incorporated the surrounding nucleus of its progenitor and lost the rest of the hosting galaxy while the two are still observable as distinct components in M54 and the surrounding field.

description: Kilometric-scale optical imagers seem feasible to realize by intensity interferometry, using telescopes primarily erected for measuring Cherenkov light induced by gamma rays. Planned arrays envision 50--100 telescopes, distributed over some 1--4 km$^2$. Although array layouts and telescope sizes will primarily be chosen for gamma-ray observations, also their interferometric performance may be optimized. Observations of stellar objects were numerically simulated for different array geometries, yielding signal-to-noise ratios for different Fourier components of the source images in the interferometric $(u,v)$-plane. Simulations were made for layouts actually proposed for future Cherenkov telescope arrays, and for subsets with only a fraction of the telescopes. All large arrays provide dense sampling of the $(u,v)$-plane due to the sheer number of telescopes, irrespective of their geographic orientation or stellar coordinates. However, for improved coverage of the $(u,v)$-plane and a wider variety of baselines (enabling better image reconstruction), an exact east-west grid should be avoided for the numerous smaller telescopes, and repetitive geometric patterns avoided for the few large ones. Sparse arrays become severely limited by a lack of short baselines, and to cover astrophysically relevant dimensions between 0.1--3 milliarcseconds in visible wavelengths, baselines between pairs of telescopes should cover the whole interval 30--2000 m.

description: To an outside observer, a black hole's event horizon appears to behave exactly like a dynamical fluid membrane. We extend this membrane paradigm to black holes in general $f(R)$ theories of gravity. We derive the stress tensor and various transport coefficients of the fluid and find that the membrane behaves as a non-Newtonian fluid except for the special case of Einstein gravity. Using Euclidean methods, we study the thermodynamics of the membrane. We speculate on what theories of gravity admit horizons with fluid properties.

The matter of experience : understanding good teaching in an international field placement
Creators: name: Riedel, Marian Ida
Publisher: name: University of British Columbia

description: Many teacher education programs, like those in BC, depict good teaching as an epistemological concern, one that can be addressed by acquiring propositional and procedural knowledge during on-campus teacher education courses and, in turn, applying this knowledge in field settings (e.g., the practicum). Such a perspective marginalizes the knowledge and insights gained from the direct experience of teaching and depicts good teaching as an application activity situated in a theory-into-practice paradigm. In an attempt to better understand the contribution of direct experience to good teaching, this study explores the international field placement component of a Bachelor of Education program for six pre-service teachers. Specifically, it examines how the pre-service teachers understand and act on their ideas about what it means to be a good teacher as a result of a four week placement in BC Offshore Schools in Asia. This hermeneutic qualitative study draws upon Hans-Georg Gadamer’s (2004) notion of Erfahrung – an experience that interrupts understandings. An analysis of the pre-service teachers’ experiences suggests that international field placements, such as those at BC Offshore Schools, can be a distinctive form of direct experience where the context provides both familiarity and strangeness – a relationship that both challenges and contributes to the participants’ thinking about the practice of good teaching in ways that may not be possible in regular BC field placements. Specifically, this study demonstrates that the pre-service teachers problematized three important dimensions of teaching: embedded Western values; universal applications of “good” pedagogy/“best practice”; and the pre-service teacher position within the field placement. These results have implications for the purpose and value of international field placement in teacher education.

description: We present the full numerical solution for the 15-dimensional space of linearized deformations of the Klebanov-Strassler background which preserve the SU(2) X SU(2) X Z_2 symmetries. We identify within this space the solution corresponding to anti-D3 branes, (modulo the presence of a certain subleading singularity in the infrared). All the 15 integration constants of this solution are fixed in terms of the number of anti-D3 branes, and the solution differs in the UV from the supersymmetric solution into which it is supposed to decay by a mode corresponding to a rescaling of the field theory coordinates. Deciding whether two solutions that differ in the UV by a rescaling mode are dual to the same theory is involved even for supersymmetric Klebanov-Strassler solutions, and we explain in detail some of the subtleties associated to this.

description: Background Disruption to everyday routine during the COVID-19 pandemic has resulted in considerable implications for global mental health. The inter- and intra-personal mechanisms by which disrupted routine can contribute to elevated depressive symptoms has not been well-explored. The present study aimed to examine how feelings of social (dis)connectedness and rumination, as a maladaptive coping strategy, could explain the association between disrupted well-being activities and depressive symptoms. Methods Participants (N = 496) ranging in age from 18 to 73 years (M = 28.73, SD = 10.93) completed an online survey within the first 3 months of the COVID-19 pandemic, which included measures of disruption to usual psychological and physical well-being activities, social connectedness, rumination, and depressive symptoms. Social connectedness and rumination were investigated as serial mediators of the association between disrupted well-being activities and depression using Hayes' PROCESS macro. Results 39.5% of the sample reported clinically significant levels of depression. Disruption to well-being activities predicted higher depressive symptoms, and this was partially explained by feelings of social disconnectedness and subsequent rumination. Rumination, alone, was not a significant mediator between disrupted routine and depressive symptoms. Limitations The cross-sectional survey design does not preclude the possibility of bidirectional effects. Conclusion The social distancing public health measures to combat COVID-19 have contributed to widespread disrupted routine, and in turn, elevated symptoms of depression. Social disconnectedness plays a particularly important role in this association. Intervention strategies should consider social factors as a ‘social cure’ for mass, positive mental health promotion during COVID-19.

description: We study the radial distribution of stars of different stellar generations in the globular cluster NGC 3201. From recently published multicolour photometry, a radial dependence of the location of stars on the giant branch was found. We coupled the photometric information to our sample of 100 red giants with Na, O abundances and known classification as first or second-generation stars. We find that giants stars of the second generation in NGC 3201 show a tendency to be more centrally concentrated than stars of the first generation, supporting less robust results from our spectroscopic analysis.

Effects of seaweed farming on tropical shallow coral ecosystems
Creators: name: Hehre, Edward James
Publisher: name: University of British Columbia
Year: 2016

description: Seascapes are being transformed by human activities through a variety of spatially extensive extractive uses. This industrialization has the potential to radically alter the ecology of our oceans. Through focused ecosystem-based management of already degraded systems, it may be possible to create novel ecosystems that maximize beneﬁts for humans, while increasing the diversity and abundance of dependent communities. In this thesis I examine seaweed farming on degraded coral reef ecosystems in order to examine 1) the relationship between seaweed farms and rabbitfish production globally, 2) the relationship between seaweed farms established on shallow coral reef ecosystems and ﬁsh assemblage composition, and 3) the diet composition of herbivorous ﬁsh in relation to the presence of seaweed farms. I found a correlation between seaweed farming and catches of rabbitfish (family Siganidae), implying farms may drive herbivorous ﬁsh catch in Southeast Asia. However, within regions, I found little evidence of increased abundance, biomass, and size of rabbitfish in areas with farms relative to those without. Therefore, the addition of farmed seaweeds was unlikely to subsidize rabbitfish diets, but replaced wild seaweeds removed by farmers. Investigation of seaweed farming activities on coral reef ﬁsh assemblages found farms negatively impacted diversity, abundance, and total biomass even in locations subject to blast ﬁshing. These results have signiﬁcant implications for the management of shallow coral ecosystems. Traditionally, areas of human use within seascapes are divided into distinct categories of use vs. wilderness. Increasingly seascapes have become patchworks of human use, and their impacts may result in diﬀerent ecological functions. The designation of an area for restoration, protection, or a particular use must be based on several factors including the potential for the activity to alter ecosystem function as well as its ecological context. A novel ecosystems approach to degraded shallow coral reef ecosystems would dictate further human activities within radically altered systems account for both the current ecological function and the entire range of options for further use rather than only focusing on use and impacts solely in terms of traditional restoration.

description: Let G be a compact Lie group. We build a tower of G-spectra over the suspension spectrum of the space of linear isometries from one G-representation to another. The stable cofibres of the maps running down the tower are certain interesting Thom spaces. We conjecture that this tower provides an equivariant extension of Miller's stable splitting of Stiefel manifolds. We provide a cohomological obstruction to the tower producing a splitting in most cases; however, this obstruction does not rule out a split tower in the case where the Miller splitting is possible. We claim that in this case we have a split tower which would then produce an equivariant version of the Miller splitting, we prove this claim in certain special cases though the general case remains a conjecture. To achieve these results we construct a variation of the functional calculus with useful homotopy-theoretic properties and explore the geometric links between certain equivariant Gysin maps and residue theory.

The minimal sense of humor and satire in storytelling of Wild Wise Weird are sure to bring readers smiles, better yet, moments of quiet reflection, a much under-appreciated remedy in the world driven almost insane with the abundance of information co-created with AI technologies. The book provides valuable life lessons and deep insights into Vietnamese village life, moral values, and social structures. The narrative not only entertains but also serves as a lively resource for cultural studies and analysis, bridging traditional storytelling with contemporary issues. This dual focus on technological introspection and cultural richness positions the work uniquely within current scholarly dialogues, making it particularly relevant to the readers who care about our quest to wisdom in the age of AI.

description: In order to promote the revitalization and development of rural areas and protect the property rights of farmers, it is necessary to explore the reasonable distribution ratio of land value-added income in collective operating construction land. Under the existing land value-added income distribution model, the land value-added income obtained by the government is much greater than that of village collectives, and it is difficult for village collectives and farmers to enjoy greater benefits. This distribution model is not conducive to protecting the property rights of farmers. The results show that there was a positive correlation between land value-added income and land level, that is, the higher the land level was, the higher the value-added income and its ratio to the market transaction price were. According to calculation, the reasonable distribution ratio of the value-added income of collective operating construction land entering the market among the government, village collectives and farmers was 28.6%, 51.1%, and 20.3% respectively. The actual land value-added income obtained by farmers was greatly improved compared with the current situation. In actual operation, this distribution mode has universal applicability. The reform of entering the market in the future also needs to raise the standards for entering the market, explore diversified interest protection channels, and strengthen the construction of rural collective management system.

In pursuit of some insight as to the most sensitive search channels, We assume that the leptoquark-lepton-quark coupling can be constructed from the known mass matrices. We estimate the rates for selected rare processes in three cases: leptoquarks carrying lepton and quark flavour, leptoquarks with quark flavour only, and unflavoured leptoquarks. We find that leptoquark decay to top quarks is an interesting search channel.

Structure-aware computational imaging
Creators: name: Heide, Felix
Publisher: name: University of British Columbia
Year: 2016

description: While traditional imaging systems directly measure scene properties, computational imaging systems add computation to the measurement process, allowing such systems to extract non-trivially encoded scene features. This dissertation demonstrates that exploiting structure in this process allows to even recover information that is usually considered to be completely lost. Relying on temporally and spatially convolutional structure, we extract two novel image modalities that were essentially “invisible” before: a new temporal dimension of light propagation, and a new per-pixel radial velocity dimension, both obtained using consumer Time-of-Flight cameras. These two novel types of images represent first steps toward the inversion of light transport. Specifically, we demonstrate that Non-Line-of-Sight imaging and imaging in scattering media can be made feasible with additional temporal information. Furthermore, structure-aware imaging also represents a completely new approach to traditional color image processing. We show that classical hand-crafted image processing pipelines can be replaced by a single optimization problem exploiting image structure. This approach does not only outperform the state-of-the-art for classical image processing problems, but enables completely new color camera designs. In particular, we demonstrate camera designs with radically simplified optical systems, as well as novel sensor designs. The computation for all imaging problems from this dissertation relies on Bayesian inference using large-scale proximal optimization methods. We present a mathematical framework and a corresponding domain-specific language to automate the development of efficient, structure-aware solvers, allowing to immediately apply the insights gained in this dissertation to new imaging problems.

description: Results are presented of searches for the production of supersymmetric particles decaying into final states with missing transverse momentum and exactly two isolated leptons in sqrt{s}=7 TeV proton-proton collisions at the Large Hadron Collider. Search strategies requiring lepton pairs with identical sign or opposite sign electric charges are described. In a data sample corresponding to an integrated luminosity of 35 pb-1 collected with the ATLAS detector, no significant excesses are observed. Based on specific benchmark models, limits are placed on the squark mass between 450 and 690 GeV for squarks approximately degenerate in mass with gluinos, depending on the supersymmetric mass hierarchy considered.

description: The performance of software components depends on several factors, including the execution platform on which the software components run. To simplify cross-platform performance prediction in relocation and sizing scenarios, a novel approach is introduced in this thesis which separates the application performance profile from the platform performance profile. The approach is evaluated using transparent instrumentation of Java applications and with automated benchmarks for Java Virtual Machines.
Orthogonal polynomials in the normal matrix model with a cubic potential

description: We consider the normal matrix model with a cubic potential. The model is ill-defined, and in order to reguralize it, Elbau and Felder introduced a model with a cut-off and corresponding system of orthogonal polynomials with respect to a varying exponential weight on the cut-off region on the complex plane. In the present paper we show how to define orthogonal polynomials on a specially chosen system of infinite contours on the complex plane, without any cut-off, which satisfy the same recurrence algebraic identity that is asymptotically valid for the orthogonal polynomials of Elbau and Felder. The main goal of this paper is to develop the Riemann-Hilbert (RH) approach to the orthogonal polynomials under consideration and to obtain their asymptotic behavior on the complex plane as the degree $n$ of the polynomial goes to infinity. As the first step in the RH approach, we introduce an auxiliary vector equilibrium problem for a pair of measures $(μ_1,μ_2)$ on the complex plane. We then formulate a $3\times 3$ matrix valued RH problem for the orthogonal polynomials in hand, and we apply the nonlinear steepest descent method of Deift-Zhou to the asymptotic analysis of the RH problem. The central steps in our study are a sequence of transformations of the RH problem, based on the equilibrium vector measure $(μ_1,μ_2)$, and the construction of a global parametrix. The main result of this paper is a derivation of the large $n$ asymptotics of the orthogonal polynomials on the whole complex plane. We prove that the distribution of zeros of the orthogonal polynomials converges to the measure $μ_1$, the first component of the equilibrium measure. We also obtain analytical results for the measure $μ_1$ relating it to the distribution of eigenvalues in the normal matrix model which is uniform in a domain bounded by a simple closed curve.

How can original swing music be composed so that it is suited to contemporary Australian swing dance?
Creators: name: Buckingham, Justin
Publisher: name: The Australian National University
Year: 2023

description: Swing music and swing dance comprise a shared artform that is often practiced separately in the present day. Swing musicians and swing dancers may have different understandings of this shared artform and the characteristics of swing music that make it suited to swing dance. Using practice-led methodology and critically reflective practice, a range of new swing music compositions were written that explored conventional understandings of the genre. These compositions also incorporated concepts unconventional to the genre to test the suitability of these concepts for swing dance. The compositions were performed at a swing dance social where data was gathered through video recording and a survey. Additionally, a focus group of expert dancers were invited to discuss the suitability of the compositions for swing dance shortly after the performance. Many conventional understandings of swing dance music were confirmed by the data. It was found that dancers and musicians had different conceptions of rhythmic energy. Unconventional concepts incorporated into the compositions were found to have mixed suitability, where some presented new and interesting challenges to swing dancers while others strayed too far from conventions of predictability and rhythm for dancers to find them suitable. This study offers insights into the differing understandings of the genre musicians and dancers may have and provides an exploration of contemporary Australian practice of swing dance music.

description: Condensates of microcavity exciton-polaritons have garnered much attention over the past decade for their potential to act as test beds for experiments with open dissipative bosonic condensates, and their capacity to host quantised vortices. A exciton-polariton is a bosonic quasiparticle consisting of an electron-hole bound pair (an exciton) strongly coupled to a photon typically confined by an optical microcavity. Polariton condensates can host vortices with quantised orbital angular momentum (OAM). The discrete, unbounded basis that these quantised OAM states comprise is attractive for storing or processing data with these systems, and thus methods for measuring and manipulating polariton vortex states are desirable. Fortunately, the state of a polariton condensate is easily accessible by measurement of its optical emission, unlocking the possibility to borrow OAM measurement techniques that are developed in the field of optics to be repurposed for use on polariton condensates. Currently, there is one method for performing these measurements that is universally used throughout the field. This is to produce an interferogram from the polariton emission, and infer the OAM and position of any quantised vortices present by an inspection of the fringe pattern. However, this method is limited in its ability to discern high-OAM states, and make quantitative measurements. In this thesis, I present an investigation into an alternative technique for measuring OAM that utilises a cylindrical lens. This technique is borrowed from applications in optics, and has not yet been applied to polariton emission. During this investigation, I found that the conventional technique that I employed to create stable polariton vortices was unexpectedly leading to an oscillatory switching between opposite OAM states. I propose a mechanism for this oscillation, and find that the predictions of this mechanism agree with the dynamics that were observed.
Measurement of the underground atmospheric muon charge ratio using the MINOS Near Detector

description: The magnetized MINOS Near Detector, at a depth of 225 meters of water equivalent (mwe), is used to measure the atmospheric muon charge ratio. The ratio of observed positive to negative atmospheric muon rates, using 301 days of data, is measured to be 1.266+/-0.001(stat.)+0.015/-0.014(syst.). This measurement is consistent with previous results from other shallow underground detectors, and is 0.108+/-0.019(stat. + syst.) lower than the measurement at the functionally identical MINOS Far Detector at a depth of 2070 mwe. This increase in charge ratio as a function of depth is consistent with an increase in the fraction of muons arising from kaon decay for increasing muon surface energies.
