description: We consider the singular behaviour of QCD scattering amplitudes in kinematical configurations where two or more momenta of the external partons become collinear. At the tree level, this behaviour is known to be controlled by factorization formulae in which the singular collinear factor is universal (process independent). We show that this strict (process-independent) factorization is not valid at one-loop and higher-loop orders in the case of the collinear limit in space-like regions (e.g., collinear radiation from initial-state partons). We introduce a generalized version of all-order collinear factorization, in which the space-like singular factors retain some dependence on the momentum and colour charge of the non-collinear partons. We present explicit results on one-loop and two-loop amplitudes for both the two-parton and multiparton collinear limits. At the level of square amplitudes and, more generally, cross sections in hadron--hadron collisions, the violation of strict collinear factorization has implications on the non-abelian structure of logarithmically-enhanced terms in perturbative calculations (starting from the next-to-next-to-leading order) and on various factorization issues of mass singularities (starting from the next-to-next-to-next-to-leading order).

description: Metaplastic breast cancer (MpBC) is a heterogeneous subtype of invasive mammary carcinoma associated with epithelial-mesenchymal transition (EMT) and cancer stem cell characteristics. Data regarding prognostic markers and potentially actionable targets for therapy are still limited. The present study aimed to characterize the immunohistochemical landscape of this rare malignancy and to identify potential prognostic factors and targets for therapy. A total of 75 patients diagnosed with MpBC over a 15-year period were included in the study. We performed immunohistochemical analyses for Ki-67 (MIB-1), epidermal growth factor receptor (EGFR), cytokeratin 5/6, vimentin, CD44, and androgen receptor (AR) and correlated their expression with clinicopathologic features and clinical outcomes. The p-values for survival analyses were corrected for multiple testing (threshold 0.01). Most tumors expressed CK5/6 (73%), EGFR (59%), CD44 (81%), and vimentin (87%). Eighty-nine percent had a high Ki-67 index. Eighty-four percent were classified as basal-like (CK 5/6 or EGFR positive). AR was expressed in 21% of the tumors. The basal-like phenotype was significantly (p = 0.009) associated with inferior disease-free (DFS) and breast-cancer-specific overall survival (BCOS) with borderline significance (p = 0.01). In addition, a low Ki-67 index was associated with improved DFS (p = 0.033) and BCOS (p = 0.03). Most MpBCs express basal markers (CK5/6, EGFR), epithelial-mesenchymal transition marker vimentin, and the stem cell marker CD44. Expression of basal-like markers was significantly related to inferior DFS. All the 11 patients with a lack of expression of basal markers survived without relapse.

description: Abstract:  Social media misinformation has become a serious societal problem, and recent research has focused on developing effective ways to counter its harmful impacts. This work investigates user-level countermeasures, or how individuals who see the misinformation respond to it directly, possibly to help stop its spread in their online communities. We designed a survey asking social media-using American adults which platforms they see the most misinformation on, how they respond, and how they would respond depending on their relationship with the person who posted that misinformation. We also ask if they have ever posted something inaccurate and what, if anything, they did when they realized this. Understanding current behavioral patterns and public opinion can inform the implementation and communication of platform- and user-level policies. Researching how to counter misinformation effectively will inform the mitigation of the harmful effects of misinformation on our online and offline discourse.
The distribution of the logarithm in an orthogonal and a symplectic family of $L$-functions
Creators: name: Hough, Bob
Publisher: name: arXiv
Year: 2011
Subjects: subject: Number Theory (math.NT)

description: We consider the logarithm of the central value $\log L(1/2)$ in the orthogonal family ${L(s,f)}_{f \in H_k}$ where $H_k$ is the set of weight $k$ Hecke-eigen cusp form for $SL_2(\mathbb{Z})$, and in the symplectic family ${L(s,χ_{8d})}_{d \asymp D}$ where $χ_{8d}$ is the real character associated to fundamental discriminant $8d$. Unconditionally, we prove that the two distributions are asymptotically bounded above by Gaussian distributions, in the first case of mean $-\frac{1}{2} \log \log k$ and variance $\log \log k$, and in the second case of mean $\frac{1}{2}\log \log D$ and variance $\log \log D$. Assuming both the Riemann and Zero Density Hypotheses in these families we obtain the full normal law in both families, confirming a conjecture of Keating and Snaith.

description: A coherent x-ray or gamma ray can be created from a dense electron beam propagating through an intense laser undulator. It is analyzed by using the Landau damping theory which suits better than the conventional linear analysis for the free electron laser, as the electron beam energy spread is high. The analysis suggests that the currently available physical parameters would enable the generation of the coherent gamma ray of up to 100 keV. The electron quantum diffraction suppresses the FEL action, by which the maximum radiation energy to be generated is limited.

Explicit lower and upper bounds on the entangled value of multiplayer XOR games

description: XOR games are the simplest model in which the nonlocal properties of entanglement manifest themselves. When there are two players, it is well known that the bias --- the maximum advantage over random play --- of entangled players can be at most a constant times greater than that of classical players. Recently, Pérez-García et al. [Comm. Math. Phys. 279 (2), 2008] showed that no such bound holds when there are three or more players: the advantage of entangled players over classical players can become unbounded, and scale with the number of questions in the game. Their proof relies on non-trivial results from operator space theory, and gives a non-explicit existence proof, leading to a game with a very large number of questions and only a loose control over the local dimension of the players' shared entanglement. We give a new, simple and explicit (though still probabilistic) construction of a family of three-player XOR games which achieve a large quantum-classical gap (QC-gap). This QC-gap is exponentially larger than the one given by Pérez-García et. al. in terms of the size of the game, achieving a QC-gap of order $\sqrt{N}$ with $N^2$ questions per player. In terms of the dimension of the entangled state required, we achieve the same (optimal) QC-gap of $\sqrt{N}$ for a state of local dimension $N$ per player. Moreover, the optimal entangled strategy is very simple, involving observables defined by tensor products of the Pauli matrices. Additionally, we give the first upper bound on the maximal QC-gap in terms of the number of questions per player, showing that our construction is only quadratically off in that respect. Our results rely on probabilistic estimates on the norm of random matrices and higher-order tensors which may be of independent interest.

Calciumoxalate auf Oberflächen von Natursteinen und Putzen

Subjects: Conservation Restoration

description: Calciumoxalate sind oft ein Bestandteil von Patina-Schichten auf Naturstein und Putzen. Als schwerlösliche Salze der Oxalsäure stellen Calciumoxalate in Patinas eine weitgehend beständige Schicht gegen saure Lösungen dar und bilden damit einen Schutz für das Substrat gegen umweltbedingte Schadensmechanismen. Basierend auf dieser Erkenntnis wurde vom opificio delle pietre dure in Florenz eine Methode zur künstlichen "Oxalatierung" entwickelt. Mit einer wässrigen Lösung von Ammoniumoxalat kann auf kalzitischen Materialien wie Kalkstein, Marmor oder Kalkputz eine ca. 10 μm dicke Schicht Calciumoxalat erzeugt werden. Diese künstliche Schicht Calciumoxalat wirkt nachweislich als Schutzschicht gegen Säuren und stellt damit ein präventives Konservierungsverfahren für kalzitische Substrate gegen umweltbedingte Schäden dar.

description: Die Ursprünge und technischen Grundlagen der Verkleidung von Architekturen mit glänzenden Oberflächen liegen im Alten Ägypten. Die griechisch-römische Antike übernahm die ägyptischen Methoden zum grossen Teil und führt sie in der römischen Antike zusammen mit Neuentwicklungen zu hoher technischer Vollendung. Die besondere Wertschätzung von glänzenden Oberflächen als wesentlicher Teil der römischen Materialästhetik ging im Mittelalter zum grossen Teil verloren und wurde erst wieder von der italienischen Renaissance aufgenommen. In der Folge entwickelten sich Glanztechniken auf Basis von antiken Techniken und italienischen Neuentwicklungen zu einem bestimmenden stilistischen Element der repräsentativen Architektur der Neuzeit mit Höhepunkten im Barock des 17. und 18. Jahrhunderts und im Historismus der zweiten Hälfte des 19. Jahrhunderts.
The salmon louse Lepeophtheirus salmonis (Caligidae) as a vector of Aeromonas salmonicida
Creators: name: Novak, Colin William
Publisher: name: University of British Columbia
Year: 2013

description: The sea louse, Lepeophtheirus salmonis, has been hypothesized to be a vector of fish pathogens and previous studies have isolated viral and bacterial pathogens from L. salmonis parasitizing farmed salmon. To examine the potential transmission of A. salmonicida by preadult and adult L. salmonis via parasitism of Atlantic salmon (Salmo salar), an in vivo bacteria-parasite challenge model was tested. Two pathogen challenge trials were performed, in which sea lice from donor (Aeromonas salmonicida-injected) fish were allocated among recipient fish for 14 days. Three hypotheses were examined: (i.) L. salmonis can acquire A. salmonicida from donor fish via parasitism; (ii.) A. salmonicida-exposed sea lice can transmit the pathogen to recipient Atlantic salmon via parasitism and (iii.) L. salmonis and A. salmonicida infections can cause synergistic effects on host fish. Sea lice acquired A. salmonicida externally (Trial 1 and 2, 100%) and internally (Trial 1, 100%) from parasitizing donor fish. Trial 1 (~44g fish) demonstrated a successful transfer of bacteria from lice to salmon (mucus, 100%; kidney, 77.3%), with a decrease (t = 5.29, df = 6, p = 0.00186) in mean fish condition factor and 59.1% cumulative fish mortality. Conversely, there was no evidence of bacteria transfer, no fish mortality and no decrease in mean fish condition factor in Trial 2 (~155g fish). In addition, histological examination revealed widespread inflammatory responses in small salmon (~46 g) infected with A. salmonicida and sea lice. Thus, preadult and adult L. salmonis can acquire and transmit A. salmonicida to recipient fish via parasitism under experimental conditions. However, the following conditions of pathogen, environment and host are required: (i.) a large inoculum of A. salmonicida (10⁶ - 10⁷ colony forming units (CFU) mL-¹), (ii.) internal acquisition of bacteria by sea lice and, (iii.) young Atlantic salmon post-smolts (~44g) as hosts.

description: I study dephasing of an underdamped nanomechanical resonator subject to random mass loading of small particles. I present a frequency noise model which describes dephasing due to attachment and detachment of particles at random points and particle diffusion along the resonator. This situation is commonly encountered in current mass measurement experiments using NEM resonators. I discuss the conditions which can lead to inhomogeneous broadening and fine structure in the modes absorption spectra. I also show that the spectra of the higher order cumulants of the (complex) vibrational mode amplitude are sensitive to the parameters characterizing the frequency noise process. Hence, measurement of these cumulants can provide information not only about the mass but also about other parameters of the particles (diffusion coefficient and attachment-detachment rates.)

description: A kind of motivic stable homotopy theory of algebras is developed. Explicit fibrant replacements for the $S^1$-spectrum and $(S^1,\mathbb G)$-bispectrum of an algebra are constructed. As an application, unstable, Morita stable and stable universal bivariant theories are recovered. These are shown to be embedded by means of contravariant equivalences as full triangulated subcategories of compact generators of some compactly generated triangulated categories. Another application is the introduction and study of the symmetric monoidal compactly generated triangulated category of $K$-motives. It is established that the triangulated category $kk$ of Cortiñas--Thom can be identified with the $K$-motives of algebras. It is proved that the triangulated category of $K$-motives is a localization of the triangulated category of $(S^1,\mathbb G)$-bispectra. Also, explicit fibrant $(S^1,\mathbb G)$-bispectra representing stable algebraic Kasparov $K$-theory and algebraic homotopy $K$-theory are constructed.

Pilot scale application of microwave technology for dairy manure treatment and nutrient recovery through struvite crystallization
Creators: name: Zhang, Hui
Publisher: name: University of British Columbia
Year: 2013

description: Excessive use of nutrients in agriculture has been significant surface and groundwater pollution sources. A pilot scale treatment process was developed for the purposes of phosphorus and ammonia recovery from dairy manure slurry. A novel advanced oxidation process combining hydrogen peroxide, microwave, and sulphuric acid was studied for its abilities to solubilise nutrients and metals in manure. The treated manure was then used for struvite crystallization to recover phosphates and ammonia in a commercially viable fertilizer form. Using dairy manure, as a phosphate source for struvite crystallization, had some foreseeable challenges. The majority of phosphorus in dairy manure slurry was insoluble, thus unsuitable for struvite crystallization. A synergistic nutrient solubilisation effect was found when manure was treated. As high as 101.7 ± 4.3% of total phosphorus was solubilised as phosphate, and 94.9 ± 4.7% of total nitrogen was solubilised as ammonia. High suspended solids concentration in manure slurry, thought to impede struvite crystallization, was also overcome through microwave treatment to destabilise manure solids from suspension. As high as 2.00 Log reduction in total suspended solids was achieved by gravity clarification. Manure contains high levels of calcium that would compete against struvite for phosphate precipitation. Oxalic acid was tested as a potential reagent to use for calcium removal from dairy manure. Up to 97.2% soluble Ca removal, by calcium oxalate precipitation was observed. The treated dairy manure was then used as influent material for struvite crystallization. Under various reaction conditions, it was found that phosphorus reduction between 69% and 99% was achievable. Roughly 25% nitrogen removal was observed under all reactor conditions. An interesting observation from the crystallization experiments was that pellet morphologies and compositions varied with reaction conditions. The potassium containing mineral hazenite was found to coexist in the struvite pellets. The ability to extract potassium from dairy manure was not only beneficial to the dairy industry, but may also create a fertilizer of higher economical and nutritional value, than struvite alone.

Our method covers toric, affine, and projective hypersurfaces and also can be used to compute the L-function of an exponential sum.

description: We consider the dynamical properties of dissipative continuous-time quantum walks on directed graphs. Using a large-deviation approach we construct a thermodynamic formalism allowing us to define a dynamical order parameter, and to identify transitions between dynamical regimes. For a particular class of dissipative quantum walks we propose a quantum generalization of the the classical PageRank vector, used to rank the importance of nodes in a directed graph. We also provide an example where one can characterize the dynamical transition from an effective classical random walk to a dissipative quantum walk as a thermodynamic crossover between distinct dynamical regimes.

description: Bei dem in dieser Facharbeit behandeltem Objekt handelt es sich um eine archäologische Blockbergung aus dem sächsischen Gräberfeld in Immenbeck, bei Buxtehude. Der Block war Bestandteil eines ca. 1500 Jahre alten Frauengrabes und wurde im Jahr 2003 von der Denkmalpflege Buxtehude geborgen. Bis zu seiner
Bearbeitung lagerte der Block mit der Fundnummer 4068 im Niedersächsischen Landesamt für Denkmalpflege in Hannover. Der Grabungsbericht und die Röntgenfotos versprachen reiche und materialvielfältige Beigaben, weshalb dieser Block für diese Bachelorthesis und eine laufende Doktorarbeit ausgewählt worden ist.
Nach der Öffnung und der schrittweisen Freilegung offenbarten sich eine Vielzahl an Glas- und Bernsteinperlen, ein graziler Silberhalsreif, zwei stark fragmentierte Scheibenfibeln, zwei Bronzeringe und eine Bügelfibel. Alle
Schmuckstücke, vor allem die eindrucksvollen Perlenreihen, schienen sich noch in ihrer „in situ“ Position zu befinden. Zusammen bildet das beeindruckende Ensemble ein markantes Beispiel für die Beigaben der sächsischen Frauengräber. Leider befanden sich die Funde durch die ungünstige Bodenlagerung und Austrocknung im Depot in einem bedauernswerten Zustand. Umso wichtiger war es, alle Befunde umfassend zu dokumentieren, analysieren, konservieren und zu restaurieren. Eben diese Maßnahmen sind Inhalt der Arbeit und bieten Einblicke in die unterschiedlichen Korrosionsprozesse und zeigen Mittel und Wege der
Schadensbegrenzung. Die gemachten Beobachtungen führen fernerhin zu einer Interpretation und
Rekonstruktion des Fundzusammenhangs. Der Restaurator begibt sich nicht nur in die Dienste des Objektes, sondern auch in die Dienste der Wissenschaft und geht so auf Spurensuche.

Zuletzt wurden die konservatorischen Maßnahmen beschrieben und dokumentiert und auf zukünftige konservatorische Schritte hingewiesen.
Die Figur wurde von Schmutz, Mikroorganismen und vom verunstaltenden Anstrich befreit. Gefährdete Schollen sind durch eine individuell hergestellte Kittmasse gesichert und Ausbruchskanten angeböscht worden. Abgebrochene Teile wurden wieder angesetzt und die sandenden und abschollenden Partien sind mit Kieselsäureester gefestigt worden.
Der Bestand wurde konservatorisch gesichert.
Applications of the gauge/gravity duality
Creators: name: Whyte, Kevin Robert Leslie
Publisher: name: University of British Columbia
Year: 2013

description: While varied applications of gauge/gravity duality have arisen in literature from studies of condensed matter systems including superconductivity to studies of quenched Quantum Chromodynamics (QCD), this thesis focuses on applications of the duality to holographic QCD-like ﬁeld theories and to inflationary model that uses a QCD-like ﬁeld theory. In particular the first half of the thesis examines a holographic QCD-like ﬁeld theory with scalar quarks closely related to the Sakai-Sugimoto model of holographic QCD. The behaviour of baryons and mesons in the model is examined to find a continuous mass spectrum for the mesons, and a baryon that can identified with a topological charge. It then slightly modifies the theory to further study the behaviour of holographic ﬁeld theories. The second half of the thesis presents a novel model for early Universe inflation, using an SU(N) gauge ﬁeld theory as the inflaton. The inflation model is studied at both weak coupling and strong coupling using the gauge/gravity duality. The robustness of model’s predictions to exciting multiple inflationary fields beyond the single ﬁeld of its original proposal, and its possible role in breaking the supersymmetry of the Minimal Supersymmetric Standard Model is also explored.

Snow Interception Relationships with Meteorology and Canopy Structure in a Subalpine Forest

description: Snow accumulation models differ in how snow interception and ablation processes are represented and thus their application to diverse climates and forest types is uncertain. Existing parameterizations of initial snow interception before unloading include inherently coupled canopy snow accumulation and ablation processes. This leads to difficulty in diagnosing processes and adding possible errors to simulations when incorporated as canopy interception routines in models that already account for canopy snow ablation. This study evaluates the theory underpinning these parameterizations using high-temporal resolution and fine-scale measurements of throughfall for events with minimal snow ablation and redistribution in both the canopy and on the ground. The relationship between these throughfall measurements, event meteorology, and a novel lidar-based measurement of canopy structure are assessed in two subalpine forest plots in the Canadian Rockies. Contrary to existing theories, no association of canopy snow load or air temperature with interception efficiency was observed. Instead, canopy structure emerged as the primary factor governing snow accumulation. A wind-driven snowfall event demonstrated that non-vertical hydrometeor trajectories can significantly increase snow-leaf contact area, thereby enhancing initial interception before ablation. Prediction of interception efficiency for this event improved dramatically when adjusted for hydrometeor trajectory angle based on a wind speed at one-third of the canopy height. Snow-leaf contact area showed a high sensitivity to wind speed, increasing by up to 95% with a 1 m s-1 wind speed. The study proposes a new parameterization that calculates throughfall, independent of processes that ablate snow from the canopy, as a function of snow-leaf contact area adjusted for hydrometeor trajectory angle. This new parameterization successfully estimated subcanopy snow accumulation for a snowfall event at two forest plots measured using lidar and snow surveys. By separating canopy snow ablation from snow interception processes, this new model offers potentially improved prediction of subcanopy snow accumulation when combined with canopy snow ablation parameterizations.

Untersuchung zur Reinigung ungefärbter Seide mit Laser

description: Untersucht wurde die Auswirkung von Laser auf ungefärbte Seidengewebe. Als Proben dienten: neue,
saubere Seide, neue Seide, welche mit Kohlenstaub künstlich verschmutzt wurde und natürlich gealterte Seide unbekannter Herkunft.

Sie wurden mit einem computergesteuerten Nd:YAG, Q-switched-Laser in 12 unterschiedlichen Kombinationen von Energiedichte und Pulsanzahl behandelt: bei 0.5, 1.0, 1.5 und 4.2 J/cm2 und mit 4, 16 und 64 Pulsen. Ein zusätzliches Probeset der künstlich verschmutzten Seide wurde mit 0.025, 0.05, 0.1, 0.2, 0.3 J/cm2 hergestellt. Das Resultat der Reinigungsproben wurde visuell und analytisch auf Veränderungen in der Seide untersucht.

Die visuelle Begutachtung erfolgte mit und ohne Mikroskop, unter VIS- sowie UV-Licht; die analytischen Untersuchungen mit Colorimetrie, focused ion beam scanning electron microscopy (FIB-SIMS), Viskosimetrie und Fourrier-Transform-Infrarot-Spektroskopie (FTIR) mit und ohne Polarisation. Beobachtet wurden Veränderungen der morphologischen Faseroberfläche, der Licht-Absorption, der Ionisierbarkeit, des Polymerisationsgrades sowie der Gesamtkristallinität und der Ausrichtung der Kristallite in der Faser.
Während unter dem Mikroskop sichtbare pyhsikalische Veränderungen erst (weit) über den hier getesteten Energiedichte-Pulszahlkombinationen erfolgen, führt die Laserbehandlung bereits ab einer Energiedichte von 0.2 J/cm2 zu einer chemischen Veränderung der Seide. Dies entspricht der minimalen Energiedichte, welche zur Entfernung der Kohlenstaubverschmutzung notwendig ist. Die Veränderung äussert sich bei kleinen Energiedichten und Pulszahlen in einer Vergilbung, bei höheren in einem Ausblassen der Seide. Gleichzeitig finden mindestens zwei verschiedene chemische Reaktionen statt, wobei bei niedrigen Energiedichten und Pulszahlen Prozesse dominant sind, welche zu polaren Gruppen führen, bei höheren Energiedichten und/oder Pulszahlen solche, die zu konjugierten Systemen führen.

Da mindestens zwei Prozesse gleichzeitig ablaufen, kann nicht automatisch das Entstehen polarer Gruppen mit Kettenbrüchen und dasjenige konjugierter Systeme mit Vernetzung gleichgesetzt werden.
Die drei Probesets erfuhren durch die Laserbehandlung verschiedene Veränderungen in unterschiedlichem Ausmass. Dies bestätigt, dass bereits vorhandene Schädigung und/oder Verschmutzung einen wesentlichen Einfluss auf die Interaktion zwischen Laser und Seide ausüben.

Insgesamt weisen die vorliegenden Ergebnisse darauf hin, dass die Laserreinigung für die chemische Struktur ungefärbter, unerschwerter Seide bereits bei niedriger Energiedichte und Pulszahl ein signifikantes Risiko darstellt, welches bei handgesteuerten Lasergeräten eher grösser sein dürfte.

description: The NJL-jet model provides a framework for calculating fragmentation functions without the introduction of ad hoc parameters. We develop the NJL-jet model to investigate dihadron fragmentation functions (DFFs) of the form $D^{h_1 h_2}_q(z_1,z_2)$. Here we studied DFFs for $q \to \{π^+ π^-\}$, $\{π^+ K^-\}$, and $\{K^+ K^-\}$,with $q = u, d, s$. The driving terms, which represent the probability of one of the hadrons being emitted in the first emission step of the quark-jet hadronization picture, dominate the solutions of the DFFs where either $z_1$ or $z_2$ is large, and $z_1$ ($z_2$) is the light-cone momentum fraction of the emitted hadron, $h_1$ ($h_2$). The higher order terms, which represent the probability of neither of the hadrons being emitted in the first emission step of the quark-jet, become more significant as $z_1$ ($z_2$) is lowered. Finally, we present a sample result for QCD evolution of DFFs, that significantly modify the model solutions when evolved to typical hadronic scale of $4 \mathrm{GeV}^2$.

description: The purpose of the study was to find out the effect of assisted sprint training on selected strength parameters among athletes. To achieve the purpose of the present study, thirty athletes from Montfort school, Yercaud, Salem District, Tamilnadu were selected as subjects at random and their ages ranged from 14 to 17 years. The subjects were divided into two equal groups at random. The subjects were divided into two equal groups of fifteen subjects each. Group I acted as Experimental Group (Assisted sprint training) and Group II acted as Control Group. Analysis of covariance was computed. It was observed that the twelve weeks of experimental group have significantly improved the selected strength parameters of athletes.
Rosafarbene Bakterien auf Wandflächen. Untersuchungen zu den Wachstumsbedingungen

description: Das Phänomen der mikrobiell induzierten rosafarbenen Verfärbungen auf Wandflächen ist bereits seit den 1960er Jahren bekannt. Von Anfang an bereitete die Kultivierung der hierfür verantwortlichen Bakterien Schwierigkeiten. Bei der Erforschung der Eigenschaften der rot pigmentierten Mikroorganismen waren bislang nur molekularbiologische Methoden erfolgreich.
Um einen Teil der grundlegenden Wachstumsbedingungen zu klären, wurden in dieser Arbeit klimatische Bedingungen, Salzbelastung und Zusammensetzung der Architekturoberflächen an zwölf betroffenen Objekten erfasst und miteinander verglichen. Die Auswertung erfolgte anhand früherer Untersuchungen sowie eigener Analysen. An allen zwölf Objekten gab es über einen längeren Zeitraum Probleme mit hoher Luftfeuchtigkeit und durchfeuchteten Wänden. Überall lag zusätzlich eine starke Belastung mit bauschädlichen Salzen vor. Die durchgeführten Analysen zeigten, dass sich in den rosabefallenen
Bereichen vor allem Natriumcarbonate konzentrierten. Die pH-Werte der Oberflächen lagen dementsprechend im alkalischen Bereich. Zu den Untergründen ließ sich feststellen, dass die rosafarbenen Bakterien immer auf Kalktünchen mit einer vermuteten organischen Beimengung beobachtet wurden. Nähere Erkenntnisse über die Art dieser Beimengungen konnten nicht erzielt werden.
Zusammenfassend lässt sich sagen, dass es in dieser Arbeit gelungen ist einen Teil der maßgeblichen Bedingungen zu erfassen, die zu dem Phänomen der rosafarbenen Bakterien auf Wandflächen führen.
A New Strategy For Solving Two Cosmological Problems in Hadron Physics

description: A new approach to solving two of the cosmological problems (CCPs) is proposed by introducing the Abbott-Deser (AD) method for defining Killing charges in asymptotic de Sitter space as the only consistent means for defining the ground-state vacuum for the CCP. That granted, Einstein gravity will also need to be modified at short-distance nuclear scales, using instead a nonminimally coupled scalar-tensor theory of gravitation that provides for the existence of QCD's two-phase vacuum having two different zero-point energy states as a function of temperature. Einstein gravity alone cannot accomplish this. The scalar field will be taken from bag theory in hadron physics, and the origin of the bag constant B is accounted for by gravity's cosmological constant - noting that the Higgs mechanism does not account for either the curved-space origin of lambda or the mass of composite hadrons. A small Hubble-scale graviton mass naturally appears external to the hadron bag, induced by lambda. This mass is unobservable and gravitationally gauge-dependent. It is shown to be related to the cosmological event horizon in asmyptotic de Sitter space.

description: We study electronic transport across a helical edge state exposed to a uniform magnetic ({$\vec B$}) field over a finite length. We show that this system exhibits Fabry-Pérot type resonances in electronic transport. The intrinsic spin anisotropy of the helical edge states allows us to tune these resonances by changing the direction of the {$\vec B$} field while keeping its magnitude constant. This is in sharp contrast to the case of non-helical one dimensional electron gases with a parabolic dispersion, where similar resonances do appear in individual spin channels ($\uparrow$ and $\downarrow$) separately which, however, cannot be tuned by merely changing the direction of the {$\vec B$} field. These resonances provide a unique way to probe the helical nature of the theory.
