description: We perform non-perturbative calculation of the π^0 to γγ transition form factor and the associated decay width using lattice QCD. The amplitude for two-photon final state, which is not an eigenstate of QCD, is extracted through an Euclidean time integral of the relevant three-point function. We utilize the all-to-all quark propagator technique to carry out this integral as well as to include the disconnected quark diagram contributions. The overlap fermion formulation is employed on the lattice to ensure exact chiral symmetry on the lattice. After examining various sources of systematic effects except for possible discretization effect, we obtain Γ=7.83(31)(49) eV for the pion decay width, where the first error is statistical and the second is our estimate of the systematic error.

description: Geographische Verbreitungsmuster von Pflanzenarten wurden in der Vergangenheit oftmals hauptsächlich auf klimatische Toleranzen der Arten zurückgeführt. Jedoch ist anzunehmen. dass das Klima meist nur eine indirekte Rolle spielt und andere Einflussfaktoren, wie biotische Interaktion oder Land-Nutzung ebenfalls bedeutend sind. Zur Überprüfung dieser Hypothese wurden verschiedene Freilandexperimente verteilt über Deutschland durchgeführt, in denen Pflanzenarten aus unterschiedlichen Herkunftsgebieten (Arealtypen) für sie jeweils günstigen und ungünstigen Klimabedingungen, biotischen Interaktionen und verschiedenen Formen der Grünlandbewirtschaftung ausgesetzt wurden. Unter Konkurrenz und Schneckenfraß zeigten die Arten kontinentaler Herkunft stärkere Einschränkungen der Wuchsleistung als Arten ozeanischer Herkunft. Verschiedene Bewirtschaftungsformen wirkten sich ebenfalls unterschiedlich aus, während klimatische Präferenzen der verschieden verbreiteten Arten nicht festgestellt werden konnten. Der Ansatz, Arten verschiedener Arealtypen zu verwenden, zeigte Erfolg und sollte auch in weiterführenden Studien stärker zur Anwendung kommen.
description: In the past, geographical distribution patterns of plant species were often mainly attributed to climatic tolerances of the species. However, it can be assumed that climate usually plays only an indirect role and that other influencing factors, such as biotic interaction or land use, are also significant. To test this hypothesis, across Germany various field experiments were carried out, in which plant species from different geographic origin (range types) were exposed to respectively favourable and unfavourable climatic conditions, biotic interactions and different forms of grassland management. Under competition and mollusk herbivory, the species of the continental range type showed stronger restrictions in growth performance than species of the oceanic range type. Different forms of management also had different effects, whereas climatic preferences of the species of different distribution could not be determined. The approach of using species of different range types was successful and should be applied more in further studies.

description: Information about the strength of gas sources in buildings has a number of applications in the area of building automation and control, including temperature and ventilation control, fire detection and security systems. Here, we consider the problem of estimating the strength of a gas source in an enclosure when some of the parameters of the gas transport process are unknown. Traditionally, these problems are either solved by the Maximum-Likelihood (ML) method which is accurate but computationally intense, or by Recursive Least Squares (RLS, also Kalman) filtering which is simpler but less accurate. In this paper, we suggest a different statistical estimation procedure based on the concept of Method of Moments. We outline techniques that make this procedure computationally efficient and amenable for recursive implementation. We provide a comparative analysis of our proposed method based on experimental results as well as Monte-Carlo simulations. When used with the building control systems, these algorithms can estimate the gaseous strength in a room both quickly and accurately, and can potentially provide improved indoor air quality in an efficient manner.

Hairpin Telomere Resolvases

Publisher: name: American Society for Microbiology

description: Covalently closed hairpin ends, also known as hairpin telomeres, provide an unusual solution to the end replication problem. The hairpin telomeres are generated from replication intermediates by a process known as telomere resolution. This is a DNA breakage and reunion reaction promoted by hairpin telomere resolvases (also referred to as protelomerases) found in a limited number of phage and bacteria. The reaction promoted by these enzymes is a chemically isoenergetic two-step transesterification without a requirement for divalent metal ions or high-energy cofactors and uses an active site and mechanism similar to that for type IB topoisomerases and tyrosine recombinases. The small number of unrelated telomere resolvases characterized to date all contain a central, catalytic core domain with the active site, but in addition carry variable C- and N-terminal domains with different functions. Similarities and differences in the structure and function of the telomere resolvases are discussed. Of particular interest are the properties of the Borrelia telomere resolvases, which have been studied most extensively at the biochemical level and appear to play a role in shaping the unusual segmented genomes in these organisms and, perhaps, to play a role in recombinational events.

description: A comprehensive overview of kaon decays is presented. The Standard Model predictions are discussed in detail, covering both the underlying short-distance electroweak dynamics and the important interplay of QCD at long distances. Chiral perturbation theory provides a universal framework for treating leptonic, semileptonic and nonleptonic decays including rare and radiative modes. All allowed decay modes with branching ratios of at least 10^(-11) are analyzed. Some decays with even smaller rates are also included. Decays that are strictly forbidden in the Standard Model are not considered in this review. The present experimental status and the prospects for future improvements are reviewed.

description: Zemente auf Kalziumsulfoaluminatbasis (CSA) wurden als Alternative zur Verringerung der CO2-Emissionen im Zementsektor genannt. In dieser Arbeit wurden Bauxitabbaurückstände für die Herstellung von CSA getestet. Diese Rückstände sind Belterra-Tone, welche die Bauxite im Amazonasgebiet bedecken, und Tone aus der Aufbereitung der Bauxitwäsche. Die Rohmehle, die aus Kalzit, Gips und Tonen bestehen, wurden mit Hilfe von Versuchsplanung und Stöchiometrie modelliert. Bis zu 38% der Tone konnten durch brennen bei 1250 °C verwertet werden. Die Klinker enthielten bis zu 45% Ye'elimit und große Mengen Belit, außerdem Brownmillerit und Fe-Perowskit. Im Vergleich zu Portlandzementen (PZ) wurde beim Klinkerprozess mindestens 30% weniger CO2 ausgestoßen. Die Haupthydrate waren Ettringit und Monosulfoaluminat. Die hergestellten Mörtel entwickelten eine ähnliche oder sogar höhere Druckfestigkeit als PZ. Beide Tonabfälle sind für die Herstellung von Ökozementen auf CSA-Basis geeignet.
description: Calcium sulfoaluminate based cements (CSA) have been quoted as an alternative to reduce CO2 emissions from the cement sector. In this work, residues of bauxite mining were tested as alumina source to produce CSA. These residues are the Belterra Clays that cover the bauxites in the Amazon and the clay from the bauxite washing beneficiation. Raw meals composed of calcite, gypsum and the clays were modelled using design of experiments and stoichiometry. Up to 38% of the clays could be used by clinkering at 1250°C. The clinkers had up to 45% of ye'elimite and high amounts of belite, besides brownmillerite and Fe-perovskite forming a discontinuous solid solution. At least 30% less CO2 was generated in the clinkering process compared to ordinary Portland cements (OPC). The main hydrates were ettringite and monosulfoaluminate. The produced mortars developed similar and higher compressive strength than an OPC. Both clay residues are suitable to produce CSA-based eco-cements.

description: An Kontaktflächen von Metalloxiden mit Metallen oder Silizium in der Silizium-Photovoltaik kann es während der Prozessierung zu Materialumverteilungen und Festkörperreaktionen kommen. Oft sind die dabei entstehenden parasitären Oxide mit erhöhten elektrischen Kontaktwiderständen verbunden, die ab initio nicht durch Eigenschaften des entsprechenden Volumenmaterials oder aktuelle theoretische Modelle vorhergesagt werden können. Im Rahmen dieser Arbeit konnten solche Schichten an der vergrabenen ITO/a-Si-Grenzfläche in SHJ-Solarzellen sowie dem NiOx/poly-Si(p+)-Übergang für Perowskit/TOPCon-Tandems erstmals nachgewiesen und Informationen über ihre Dicke und Kristallinität gewonnen werden. Es zeigte sich, dass sie stets amorph und nur 1-10 nm dick sind. Mit hochauflösenden XPS-, ToF-SIMS- und (S)TEM-EDX/EELS-Untersuchungen konnten chemische Gradienten und lokale Unterschiede in der Bandlücke der parasitären Oxide abgeschätzt und mit dem makroskopischen Kontaktwiderstand korreliert werden.
description: Material redistributions and solid-state reactions can occur at contact interfaces of metal oxides with metals or silicon in silicon photovoltaics during processing. Often, the resulting parasitic oxides are associated with increased electrical contact resistances, which cannot be predicted ab initio by properties of the corresponding bulk material or current theoretical models. In this work, such layers were detected for the first time at the buried ITO/a-Si interface in SHJ solar cells and the NiOx/poly-Si(p+) junction for perovskite/TOPCon tandems, and information on their thickness and crystallinity was obtained. They were found to be always amorphous and only 1-10 nm thick. High-resolution XPS, ToF-SIMS, and (S)TEM-EDX/EELS studies were used to estimate chemical gradients and local differences in the band gap of the parasitic oxides. Furthermore, nanoscopic data was correlated with macroscopic contact resistances to understand contact formation in those material systems.

description: We investigate the constraints on neutron star mass and radius in GS 1826-24 from models of lightcurves and spectral evolution of type I X-ray bursts. This source shows remarkable agreement with theoretical calculations of burst energies, recurrence times, and lightcurves. We first exploit this agreement to set the overall luminosity scale of the observed bursts. When combined with a measured blackbody normalization, this leads to a distance and anisotropy independent measurement of the ratio between the redshift 1+z and color correction factor f_c. We find 1+z=1.19-1.28 for f_c=1.4-1.5. We then compare the evolution of the blackbody normalization with flux in the cooling tail of bursts with predictions from spectral models of Suleimanov et al. (2011b). The observations are well described by the models at luminosities greater than about one third of the peak luminosity, with deviations emerging at luminosities below that. We show that this comparison leads to distance independent upper limits on R_\infty and neutron star mass of R_\infty\lesssim 9.0-13.2 km and M<1.2-1.7 M_\odot, respectively, for solar abundance of hydrogen at the photosphere and a range of metallicity and surface gravity. The radius limits are low in comparison to previous measurements. This may be indicative of a subsolar hydrogen fraction in the GS 1826-24 photosphere, or of larger color corrections than that predicted by spetral models. Our analysis also gives an upper limit on the distance to GS 1826-24 of d<4.0-5.5 kpc ξ_b^{-1/2}, where ξ_b is the degree of anisotropy of the burst emission.

description: Lyme borreliosis, also known as Lyme disease, is now the most common vector transmitted disease in the northern hemisphere. It is caused by the spirochete Borrelia burgdorferi and related species. In addition to their clinical importance, these organisms are fascinating to study because of the wide variety of unusual features they possess. Ongoing work in the laboratory in several areas will be described. (1) The segmented genomes contain up to two dozen genetic elements, the majority of which are linear with covalently closed hairpin ends. These linear DNAs also display a very high degree of ongoing genetic rearrangement. Mechanisms for these processes will be described. (2) Persistent infection by Borrelia species requires antigenic variation through a complex DNA rearrangement process at the vlsE locus on the linear plasmid lp28-1. Novel features of this recombination process will be presented. (3) Evidence for a new global regulatory pathway of B. burgdorferi gene expression that is required for pathogenicity will be described. The DEAH box RNA helicase HrpA is involved in this pathway, which may be relevant in other bacteria. (4) The mechanism of B. burgdorferi to effectively disseminate throughout its host is being studied in real time by high resolution intravital imaging in live mice. Recent work will be presented.
From campus to classroom : a study of elementary teacher candidates’ pedagogical content knowledge

description: In this study, I explored a cohort of elementary teacher candidates’ Pedagogical Content Knowledge (PCK) and how it was influenced before, during, and after participation in a science methods course and extended practicum experience in a 12-month teacher education programme at a University in Western Canada. I adopted a case study approach that employed a mixed methods perspective to investigate the effect of the science teaching methods course and extended practicum on the participants’ PCK. I administered a non-disguised, self-enumerated, online questionnaire to assess and interpret the candidates’ PCK. I also elicited and interpreted their views on their experiences through semi-structured interviews using phenomenographic methods. My findings indicate the students who entered the program and participated in the online questionnaire had a PCK level of 7 out a maximum of 11 (M=7.1431, SD=1.07794). The teacher candidates I interviewed believed they possessed awareness of PCK from prior experiences including being science students at both elementary and secondary levels and during volunteer experiences. At the end of their science teaching methods course, teacher candidates participating in the on-line questionnaire scored a PCK level of 8 out of a maximum of 11 (M=8.0719, SD=1.03280); those interviewed attributed their increased PCK level to working with their science methods instructor in the Teacher Education Programme. At the end of the extended practicum, the same teacher candidates were again surveyed by completing the same online questionnaire. Analysis and interpretation of their responses indicated their PCK level as having dropped to 7 out of a maximum of 11 (M=7.0783, SD=0.72437). My analysis of the follow-up interviews with the teacher candidates showed that their relationship with the school advisor and the real world teaching experience of the practicum influenced the drop in PCK. My research provides insight into teacher candidates’ PCK as they progress through a 12-Month Teacher Education Programme. It illustrates that experiences including time spent as science learners in elementary and secondary classrooms, during volunteer experiences, gaining admission into a teacher education programme, interacting with experts in teaching methods, and immersion in the real-world teaching context of the classroom are powerful factors in teacher candidates’ PCK.

An investigation of sustainability-oriented courses : student views and experiences

Year: 2012

description: With an increased awareness of climate change and environmental concerns, and a worldwide call for the integration of sustainability into the curriculum, universities are looked upon as agents of change to incorporate and integrate sustainability into their operations, research, teaching and learning. To address this call for leadership, institutions of higher education are incorporating a focus on sustainability into their mission statements, policies, practices and courses. In 1997, the University of British Columbia (UBC), Vancouver, was the first Canadian university to adopt a sustainable development policy, and today, UBC continues the pursuit of sustainability education leadership by preparing its students to be global citizens. This study investigated students’ learning experiences in UBC courses that teach about sustainability, as well as students’ perceptions and views towards what is valued for their understanding of sustainability concepts and pedagogies. The study examined students’ understanding and awareness of sustainability and their views on their own learning through an in-depth qualitative analysis approach that involved focus groups, one-on-one interviews, classroom observations, and document analysis. Findings indicate two factors play a role in students’ understanding and integration of knowledge of sustainability concepts and their motivation to engage in sustainability-related activities: 1) multi-disciplinary environments and peer interactions that involved project-based group work and 2) philosophical and holistic discussions of sustainability-related issues. Data analysis also indicated that while participating in sustainability-oriented courses increased students’ interest in sustainability, students felt restricted in their exploration of the issues due to the strict degree and program requirements imposed by the university departments. Findings from this study inform future course design and the development of a comprehensive and cohesive sustainability curricula at UBC and other institutions of higher education.

description: In bilayer graphene, the phase diagram in the plane of a strain-induced bare nematic term, ${\cal N}_{0}$, and a top-bottom gates voltage imbalance, $U_{0}$, is obtained by solving the gap equation in the random-phase approximation. At nonzero ${\cal N}_0$ and $U_0$, the phase diagram consists of two hybrid spin-valley symmetry-broken phases with both nontrivial nematic and mass-type order parameters. The corresponding phases are separated by a critical line of first- and second-order phase transitions at small and large values of ${\cal N}_0$, respectively. The existence of a critical end point, where the line of first-order phase transitions terminates, is predicted. For ${\cal N}_0=0$, a pure gapped state with a broken spin-valley symmetry is the ground state of the system. As ${\cal N}_{0}$ increases, the nematic order parameter increases, and the gap weakens in the hybrid state. For $U_{0}=0$, a quantum second-order phase transition from the hybrid state into a pure gapless nematic state occurs when the strain reaches a critical value. A nonzero $U_{0}$ suppresses the critical value of the strain. The relevance of these results to recent experiments is briefly discussed.

In dieser Dissertation wird der prototypische OQC im Ba-Ti-O-System mit einer erstmalig beschriebenen Approximantenstruktur nicht bekannter Komplexität im Sr-Ti-O-System verglichen. Neben den strukturellen Eigenschaften wird besonderer Fokus auf die nahezu unerforschten elektronischen Merkmale der Strukturen gelegt. Die Topografie wird mithilfe der Rastertunnelmikroskopie bei ultratiefen Temperaturen untersucht und das atomare Muster mithilfe eines computergestützten Algorithmus statistisch analysiert. Die Bestimmung elektronischer Eigenschaften erfolgt durch Rastertunnelspektroskopie. Insbesondere werden Unterschiede der elektronischen Eigenschaften durch Aufnahme lokaler Punktspektren sowie Leitfähigkeitskarten identifiziert und interpretiert.
description: The discovery of a two-dimensional oxide quasicrystal (OQC) in 2013 expanded the research field of quasicrystals. The OQC originates from a BaTiO3-based layer and exhibits a 12-fold symmetry. This thesis compares the prototypical OQC in the Ba-Ti-O system with a newly described approximant structure of unknown complexity in the Sr-Ti-O system. In addition to the structural properties, particular emphasis is placed on the virtually unexplored electronic characteristics of the structures. The topography is examined using scanning tunneling microscopy at ultra-low temperatures and the atomic pattern is statistically analyzed using a computer-assisted algorithm. The determination of electronic properties is carried out through scanning tunneling spectroscopy. In particular, differences in electronic properties are identified and interpreted through the acquisition of local point spectra and conductivity maps.

description: Wir stellen unsere computergestützte Bildtypenanalyse mittels CLIP am Beispiel einer Analyse visueller Social Media-Inhalte vor und evaluieren diese. Dabei betrachten wir 2208 Instagram Stories aus dem Bundestagswahlkampf 2021, die in den letzten zwei Wochen des Wahlkampfs auf den Kanälen von acht Parteien und 14 Spitzenkandidierenden veröffentlicht wurden. Durch die Bildtypenanalyse konnten wir feststellen, dass der Großteil der Stories Wahlkampfveranstaltungen dokumentiert und in einem kleineren Teil Inhalte anderer Plattformen und Formate geteilt werden. Bei ca. einem Fünftel der Stories stehen sachpolitische Themen im Mittelpunkt. Die automatisierte Klassifikation hat insgesamt mittelmäßig funktioniert, ein Teil der Bildtypen konnte aber mit guter Performance klassifiziert werden. Deshalb sehen wir den Bedarf für systematisches Prompt Engineering und schlagen eine Few-Shot / Ensemble Klassifikation in zukünftigen Vorhaben zu testen, um die Performance über alle Bildtypen zu erhöhen.

description: The specifications of file and directory paths in forensic artifacts of Windows 1x systems are not uniform. A correlation of paths is needed to prove the hypothesis that two paths in different artifacts describe the same file. During runtime of Windows, this correlation is managed inside the NT Object Manager [Al22]. The available information of the NT Object Manager is lost when Windows is shut down, so an analyst with the appropriate knowledge and experience must perform the correlation of paths manually. A mapping of the NT Object Manager is required to develop forensic tools that allow an automated correlation of paths. The mapping was used to develop a reconstruction approach based on an empirical study of differently configured Windows 1x systems. This allows for post-mortem path correlation using non-volatile data.

description: We present an overview of inflationary models derived from string theory focusing mostly on closed string moduli as inflatons. After a detailed discussion of the eta-problem and different approaches to address it, we describe possible ways to obtain a de Sitter vacuum with all closed string moduli stabilised. We then look for inflationary directions and present some of the most promising scenarios where the inflatons are either the real or the imaginary part of Kaehler moduli. We pay particular attention on extracting potential observable implications, showing how most of the scenarios predict negligible gravitational waves and could therefore be ruled out by the Planck satellite. We conclude by briefly mentioning some open challenges in string cosmology beyond deriving just inflation.

Soft physics: healing the mind/body split in physics education
Creators: name: Pfeiffer, Benoite Jeanne Françoise
Publisher: name: University of British Columbia
Year: 2012

description: Physics education is facing a crisis of meaning: students can “plug” numbers into formulas, but research shows they do not give much meaning to physical concepts. This thesis explores how the cultural context of physics education, in particular the mind/body cartesian split, contributes to a loss of meaning. Drawing from sensory scholarship, cognitive linguistics, feminist critiques of science, her own teaching experience and education research on student misconceptions and intuitive knowledge, the author challenges the mind/body dichotomy by exploring how the body can make sense of the physical world through the senses. Physical concepts can be more-than-representational, exist beyond mathematical symbols and signifiers, but nevertheless be perceived through touch. In her quest for a mind/body truce, the author has created provocative stories for the physics classroom that welcome the body and its physic-al knowledge, and that reconcile intuition and Newtonian physics. This subtle change of perspective leads her to replace the alleged mind/body war with a respectful quest for compromise and fine tuning, and to analyze the dominant patriarchal narratives of the physics community. The author advocates for an intuition-based, sensory, student-centred pedagogy that redefines traditional power relationships in the physics classroom and challenges indoctrinating scientific discourses, hoping it will contribute to improving the inclusiveness of the physics community. Such a paradigm shift requires a re-storying of collective narratives. Physics is not about dominating nature but about learning from nature; it is time to abandon the myth of the detached observer and study nature from inside, at the confluence of everything that make us humans.

description: On February 23, 2010, in New York City, the National Center for Disaster Preparedness at Columbia University Mailman School of Public Health (NCDP) convened a unique roundtable of experts to discuss the impacts on a major U.S. city and the surrounding region, of the detonation by terrorists of a 10-kiloton improvised nuclear device. Aware of the immediate impact of such a major catastrophic event, participants were nonetheless asked to focus on potential conditions and challenges in the affected region three days following the attack. The goal of the roundtable was to understand the nature and scope of these challenges and to frame questions considered essential for appropriate planning. Day Three was premised on the notions that (a) while nuclear terrorism is a low probability event, it is by no means far-fetched; (b) consequences would be devastating and (c) emergency response planning to date falls far short in terms of assuring regional readiness at an appropriate scale. A summary of the proceedings of this "not for attribution" conference comprises the body of this report.

description: Recent cuts in the federal budget have serious implications for the country's preparedness and response standing. In mid-May, federal agencies released their final FY11 budgets. Much of the country's funding for homeland security and public health preparedness resides in the Department of Health and Human Services (DHHS) and Department of Homeland Security (DHS) budgets. Preparedness and response funding within DHHS and DHS dropped by nearly $900 million, from $5.3 billion in FY10 to $4.4 billion in FY11, a 17% overall reduction.
