description: Schrödinger cat states are useful for many applications, ranging from quantum information processing to high-precision measurements. In this paper we propose a conceptually new method for creating such cat states, based on photon-assisted Landau-Zener-Stückelberg interferometry in a hybrid system consisting of a qubit coupled to a photon cavity. We show that by initializing the qubit in one of its basis states, performing three consecutive sweeps of the qubit energy splitting across the 1-photon resonance, and finally projecting the qubit to the same basis state, the parity of the photon field can be purified to very high degree; when the initial photon state is a coherent state, the final state will then be very close to a Schrödinger cat state. We present numerical simulations that confirm that our protocol could work with high fidelity ($\sim 0.99$) for coherent states of reasonable size ($|α|^2 \sim 10$). Furthermore, we suggest that our protocol can also be used to transfer quantum information between the qubit and a superposition of orthogonal cat states in the cavity.

The role of ING homologs in the yeast Saccharomyces cerevisiae
Creators: name: Martin, David Greg Edward
Publisher: name: University of British Columbia
Year: 2010

description: The yeast inhibitor of growth (ING) homolog, Ynglp, was identified based on sequence similarity of its highly conserved plant homeodomain (PHD) finger with other ING family members. Ynglp has been shown to be a stable subunit of the NuA3 histone acetyltransferase (HAT) complex. While previous work has indicated the requirement of Ynglp for NuA3 function, little was known regarding its role within the NuA3 complex. The &4.SJ-dependent HAT NuA3 was characterized through in vitro studies as having specificity towards histone H3. Whether NuA3 acetylates histones in vivo or what factors influence the binding of NuA3 with the nucleosome was also unknown. Using a chromatin pull-down assay, in conjunction with genetic studies, we show that Ynglp is required by NuA3 for its interaction with the nucleosome, and this interaction occurs within the histone H3 tail. Additionally, we show that mutation of lysine 14, the preferred site of NuA3 acetylation in vitro, shows the same phenotype as a sas3A specific phenotype indicating that modification of this residue is important for NuA3 function. The interaction of NuA3 is dependent upon Setlp and Set2p methyltransferases, as well as their substrates, histone H3 lysine residues 4 and 36 respectively. These results indicate that NuA3 is functioning as a histone acetyltransferase in vivo, and that methylation serves as a mark for the recruitment of NuA3 to the nucleosome. Through the use of additional chromatin pull-down experiments, we extend our investigation to assess whether two other yeast TNG homologs, Yng2p and Pho23p, (found in the NuA4 HAT and Rpd3-Sin3 histone deacetylase complexes respectively) perform similar functions to Ynglp within their respective complexes. Finally, we show that over-expression of human ING2, like YNG1, is toxic within yeast. Having shown that Ynglp interacts with the nucleosome, we discuss the possibility of human ING proteins functioning in a similar manner.

description: The connection between contradictory public opinions, heterogeneous believes and the emergence of democratic or dictatorial extremism is studied extending our former two state dynamic opinion model. Agents are attached to a social-cultural class. At each step they are distributed randomly in different groups within their respective class to evolve locally by majority rule. In case of a tie the group adopts either one opinion with respective probabilities k and (1-k). The value of k accounts for the average of individual biases driven by the existence of heterogeneous believes within the corresponding class. It may vary from class to class. The process leads to extremism with a full polarization of each class along either one opinions. For homogeneous classes the extremism can be along the initial minority making it dictatorial. At contrast heterogeneous classes exhibit a more balanced dynamics which results in a democratic extremism. Segregation among subclasses may produce a coexistence of opinions at the class level thus averting global extremism. The existence of contradictory public opinions in similar social-cultural neighborhoods is given a new light.

description: Objectives. Upon immersion in water, a cascade of human physiological responses is evoked, which may result in drowning death. Although lifejackets are over 80% effective in preventing drowning, many people in lakeside fishing communities in Uganda shy away from wearing them because of active distrust in the quality of the lifejackets on the local market. No study has determined the veracity of these claims. This study determined the seaworthiness of lifejackets sold at landing sites of Lake Albert, Uganda. Methods. Using a within-person repeated assessment design, we tested 22 new lifejacket samples obtained from landing sites of Lake Albert, Uganda. We conducted water entry, righting, floatation stability and minimum buoyancy performance tests. Results. All the lifejacket samples failed the minimum buoyancy functional requirements test; the average buoyancy was 80 N (SD 13). Only 4% of the lifejackets passed the righting test within 5 s. For floatation stability, 45% of the lifejackets sank earlier than 48 h of placement in water and also failed water entry tests by getting dislodged from the wearer. Conclusion. The lifejackets sold at the landing sites of Lake Albert do not meet minimum seaworthiness functional requirements. The government should regulate the quality of lifejackets on the local market.

Gravitational Instability of the Vacuum and the Cosmological Constant Problem
Creators: name: Moffat, J. W.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A mechanism for suppressing the cosmological constant is described, using a superconducting analogy in which fermions coupled to gravitons are in an unstable false vauum. The coupling of the fermions to gravitons and a screened attractive interaction among pairs of fermions generates fermion condensates with zero momentum and a phase transition induces a non-perturbative transition to a true vacuum state. This produces a positive energy gap $Δ$ in the vacuum energy identified with $\sqrtΛ$, where $Λ$ is the cosmological constant. In the strong coupling limit, a large cosmological constant induces a period of inflation in the early universe, followed by a weak coupling limit in which $\sqrtΛ$ vanishes exponentially fast as the universe expands due to the dependence of the energy gap on the Fermi surface fermions, predicting a small cosmological constant in the early universe.

description: Quantum Zakharov equations are obtained to describe the nonlinear interaction between quantum Langmuir waves and quantum ion-acoustic waves. These quantum Zakharov equations are applied to two model cases, namely the four-wave interaction and the decay instability. In the case of the four-wave instability, sufficiently large quantum effects tend to suppress the instability. For the decay instability, the quantum Zakharov equations lead to results similar to those of the classical decay instability except for quantum correction terms in the dispersion relations. Some considerations regarding the nonlinear aspects of the quantum Zakharov equations are also offered.

The in efficiency have been expressed by the coefficients cost-absorption, productivity, and efficiency of grain production in Poland. The range covered a long period of time, i.e. 20 years. The survey was conducted from the perspective of the two sub-periods. First, the pre-accession took over the years 1994-2003, the second entered into in the years 2004-2013. This made it possible to give a comparative considerations. Based on the survey, it turned out that, despite the high degree of concentration and specialization of chicken farms in the market efficiency of production of poultry and eggs remained at a relatively low level. This confirms therefore that manufacturers operate in conditions so. „technological treadmill.”

description: What fiscal policies do or do not lend credence to the concept of sustainable development? Conceptually development labels often serve to define the socio-economic progress of a nation to further influence appropriate political policy. Policy making regarding sustainable development on a national and international level is inconsistent with the current standard of growth policies within India. Current growth policies represent a systematic strategy for growth that do not always incorporate sustainable development principles. An examination and study of the National Capital Territory of Delhi will be conducted to find evidentiary data of sustainable development potential. Investigating history following 1980 and analyzing current data will be used to identify the core issues within achieving sustainable development. To rectify the hindrances to Delhi-s sustainable development data analysis will support expanding better technology Waste-to-Energy incineration projects through calculating a subsidy financed by revenue from a developmental income tax.
A Faraday Rotation Template for the Galactic Sky

description: Using a set of compilations of measurements for extragalactic radio sources we construct all-sky maps of the Faraday Rotation produced by the Galactic magnetic field. In order to generate the maps we treat the radio source positions as a kind of "mask" and construct combinations of spherical harmonic modes that are orthogonal on the masked sky. As long as relatively small multipoles are used the resulting maps are quite stable to changes in selection criteria for the sources, and show clearly the structure of the local Galactic magnetic field. We also suggest the use of these maps as templates for CMB foreground analysis, illustrating the idea with a cross-correlation analysis between the Wilkinson Microwave Anisotropy Probe (WMAP) data and our maps. We find a significant cross-correlation, indicating the presence of significant residual contamination.

description: The research is an attempt of examination of the macroeconomic relation between prices, productivity and incomes in agriculture in Poland in the context of the changes of the CAP. The Authors explain this relation and confirm the existence of market failure in agriculture in Poland in macroeconomic approach. The developed model proves the existence of puzzling, exchangeable relationship between real productivity of production factors in agriculture and agricultural income (economic surplus) under adaptive expectations. It also stems from the dominant influence of sector price scissors, not productivity on incomes. The authors hypothesize that there is a need to correct market mechanism in agriculture, but subsidies do not fulfill the corrective role, capturing the effect of King.

description: The Galactic magnetic field plays an important role in the evolution of the Galaxy, but its small-scale behaviour is still poorly known. It is also unknown whether it permeates the halo of the Galaxy or not. By using observations of pulsars in the halo globular cluster 47 Tucanae, we probed the Galactic magnetic field at arcsecond scales for the first time and discovered an unexpected large gradient in the component of the magnetic field parallel to the line of sight. This gradient is aligned with a direction perpendicular to the Galactic disk and could be explained by magnetic fields amplified to some 60 μG within the globular cluster. This scenario supports the existence of a magnetized outflow that extends from the Galactic disk to the halo and interacts with the studied globular cluster.

description: LEGEND, the Large Enriched Germanium Experiment for Neutrinoless $ββ$ Decay, is a ton-scale experimental program to search for neutrinoless double beta ($0νββ$) decay in the isotope $^{76}$Ge with an unprecedented sensitivity. Building on the success of the low-background $^{76}$Ge-based GERDA and MAJORANA DEMONSTRATOR experiments, the LEGEND collaboration is targeting a signal discovery sensitivity beyond $10^{28}\,$yr on the decay half-life with approximately $10\,\text{t}\cdot\text{yr}$ of exposure. Signal readout electronics in close proximity to the detectors plays a major role in maximizing the experiment's discovery sensitivity by reducing electronic noise and improving pulse shape analysis capabilities for the rejection of backgrounds. However, the proximity also poses unique challenges for the radiopurity of the electronics. Application-specific integrated circuit (ASIC) technology allows the implementation of the entire charge sensitive amplifier (CSA) into a single low-mass chip while improving the electronic noise and reducing the power consumption. In this work, we investigated the properties and electronic performance of a commercially available ASIC CSA, the XGLab CUBE preamplifier, together with a p-type point contact high-purity germanium detector. We show that low noise levels and excellent energy resolutions can be obtained with this readout. Moreover, we demonstrate the viability of pulse shape discrimination techniques for reducing background events.

description: LaAgSb$_{2}$ is a rare material, which offers the opportunity to investigate the complex interplay between charge density wave (CDW) ordering and topology protected electronic band structure. As both of these phenomena are governed by the structural symmetries, a comprehensive study of the lattice dynamics is highly desirable. In this report, we present the results of temperature and pressure dependent Raman spectroscopy and x-ray diffraction in single crystalline LaAgSb$_{2}$. Our results confirm that Raman spectroscopy is a highly sensitive tool to probe CDW ordering phenomenon, particularly the low-temperature second CDW transition in LaAgSb$_{2}$, which appears as a very weak anomaly in most experiments. The crystal orientation-dependent measurements provide the evolution of Raman modes with crystallographic symmetries and can be further studied through group symmetry analysis. The low-temperature x-ray diffraction data show the emergence of structural modulations corresponding to the CDW instability. The combined high-pressure Raman spectroscopy and synchrotron x-ray diffraction reveal multiple structural phase transitions through lowering of crystalline symmetries, which are also expected to lead to electronic topological transitions.
Land use impacts on ground and surface water quality in the Bertrand Creek watershed (Township of Langley, B.C.)
Creators: name: Solano, Maria Gabriela
Publisher: name: University of British Columbia
Year: 2010

description: Bertrand Creek is a small transboundary watershed with mixed land use that provides a good case study to compare the impacts of urban and agricultural activities on water resources. Located in southeastern Langley, it encompasses the city of Aldergrove and an agricultural area that extends from south of Aldergrove to the Canada - US international border. The main goal of this study was to determine land use impacts on water quality. Water samples were analyzed for nutrients and dissolved elements and results were linked to land use through a GIS. Streambed sediments were analyzed for trace metals and bioavailability of metals was measured along Bertrand Creek using the diffusive gradients in thin films (DGT) technique. Land use didn't seem to be correlated to groundwater quality but results indicated that nitrate contamination in the Abbotsford aquifer is a concern. Well depth appeared to have a significant influence in the quality of groundwater and only wells <15 m deep exceeded the drinking water quality guidelines for NO₃ - N. Surface water analysis indicated high concentrations of nitrate and phosphorus, especially on Howes Creek. Correlation with land use data showed that high concentrations of manganese in surface water and concentrations of copper, lead and zinc in sediments were positively correlated to the extent of impervious surfaces. Nitrate - N concentrations were influenced by agricultural activities particularly during the wet season. It is therefore important that stormwater and agricultural best management practices be exercised, including the increase of riparian buffer areas, improved manure management and storage techniques and the construction of stormwater detention ponds, particularly at sites that receive direct runoff from heavily used roads. Despite the importance of the streams in this watershed to aquatic life there appears to be a significant lack of water quality studies and monitoring. The results of the present study warrant further research in the watershed to ensure a healthy habitat for aquatic life and to protect drinking water sources in rural areas.

Problem-orientable numerical algorithm for modelling multi-dimensional radiative MHD flows in astrophysics -- the hierarchical solution scenario
Creators: name: Hujeirat, A. A.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Mathematical Physics (math-ph)

description: We present a hierarchical approach for enhancing the robustness of numerical solvers for modelling radiative MHD flows in multi-dimensions. This approach is based on clustering the entries of the global Jacobian in a hierarchical manner that enables employing a variety of solution procedures ranging from a purely explicit time-stepping up to fully implicit schemes. A gradual coupling of the radiative MHD equation with the radiative transfer equation in higher dimensions is possible. Using this approach, it is possible to follow the evolution of strongly time-dependent flows with low/high accuracies and with efficiency comparable to explicit methods, as well as searching quasi-stationary solutions for highly viscous flows. In particular, it is shown that the hierarchical approach is capable of modelling the formation of jets in active galactic nuclei and reproduce the corresponding spectral energy distribution with a reasonable accuracy.

Um die optimale Fahrer- und Beifahrerhaltung zu finden, werden Simulationen für stationäre Kurvenfahrt auf der Ebene ohne Schräglage durchgeführt. Ein Weg um vereinfachte Modelle der Kutschen bezüglich ihrer Trägheitstensoren zu erstellen, sowie die Ergebnisse für eine Marathon- und eine Dressurkutsche werden vorgestellt. Weiters werden charakteristische Körperhaltungen von Fahrer und Beifahrer identifiziert und mittels des Hanavan-Modells mathematisch modelliert. Diese identifizierten Haltungen werden des weiteren bezüglich der Empfindlichkeit des Trägheitstensors und der Schwerpunktslage bezüglich kleiner Abweichungen der Haltung analysiert. Abschließend wird das erstellte dynamische Modell von Kutsche inklusive Fahrer und Beifahrer vorgestellt und für Simulationen angewandt, sowie die Ergebnisse für unterschiedliche Kombinationen von Fahrer und Beifahrerhaltung präsentiert. Auch einige Sonderfälle des dynamischen Verhaltens bei Kurvenfahrt, wie enge Kurven oder der Einfluss von Beschleunigung, werden untersucht.
description: This diploma thesis investigates the influence of human mass and posture on the rollover characteristics of carriages, especially concerning carriage racing. To find the optimal postures, simulations were performed for driving through a curve with steady velocity and a planar floor without tilt. In order to estimate the inertia-tensor, simplified models of the carriages are introduced. Examples of the results for a marathon and a dressage carriage are given. Also, characteristic postures of driver and groom are identified and modelled using the mathematical model of Hanavan [6]. These identified postures are further investigated concerning variations of their inertia tensors as well as their centre of gravity depending on posture. Finally, a dynamic model of the carriage including the humans is introduced and simulated. Results are given concerning various postures for driver and groom combinations. Special cases of dynamic behaviour like sharp cornering or the influence of acceleration are analysed as well.

description: We consider an arbitrary continuous-variable three-party Gaussian quantum state which is used to perform quantum teleportation of a pure Gaussian state between two of the parties (Alice and Bob). In turn, the third party (Charlie) can condition the process by means of local operations and classical communication. We find the best measurement that Charlie can implement on his own mode that preserves the Gaussian character of the three-mode state and optimizes the teleportation fidelity between Alice and Bob.

description: On the scale of galactic haloes, the distribution of matter in the cosmos is affected by energetic, non-gravitational processes; so-called baryonic feedback. A lack of knowledge about the details of how feedback processes redistribute matter is a source of uncertainty for weak-lensing surveys, which accurately probe the clustering of matter in the Universe over a wide range of scales. We develop a cosmology-dependent model for the matter distribution that simultaneously accounts for the clustering of dark matter, gas and stars. We inform our model by comparing it to power spectra measured from the BAHAMAS suite of hydrodynamical simulations. As well as considering matter power spectra, we also consider spectra involving the electron-pressure field, which directly relates to the thermal Sunyaev-Zel'dovich (tSZ) effect. We fit parameters in our model so that it can simultaneously model both matter and pressure data and such that the distribution of gas as inferred from tSZ has influence on the matter spectrum predicted by our model. We present two variants; one that matches the feedback-induced suppression seen in the matter-matter power spectrum at the per-cent level and a second that matches the matter-matter data slightly less well (~2 per cent), but that is able to simultaneously model the matter-electron pressure spectrum at the ~15 per-cent level. We envisage our models being used to simultaneously learn about cosmological parameters and the strength of baryonic feedback using a combination of tSZ and lensing auto- and cross-correlation data.

description: With the help of a Stueckelberg field we construct a regularized U(1) gauge invariant action through the introduction of cutoff functions. This action has the property that it converges formally to the unregularized action of QED when the ultraviolet cutoff goes to infinity. Integrating out exactly the Stueckelberg field we obtain a simple effective regularized action, which is fully gauge invariant and gives rise to the same prediction as QED at the tree level and to the one loop order.

description: We report on the first frequency ratio measurement of an $^{115}$In+ single ion clock and a $^{87}$Sr optical lattice clock. A hydrogen maser serves as a reference oscillator to measure the ratio by independent optical combs. Over more than 90 000 seconds of measurement time, the frequency ratio $f_{\rm{In^+}}/f_{\rm{Sr}}$ is determined to be 2.952 748 749 874 863 4(21) with relative uncertainty of $7.0 \times 10^{-16}$. The measurement creates a new connection in the network of frequency ratios of optical clocks.

description: Resolving low-energy features in the density of states (DOS) holds the key to understanding wide variety of rich novel phenomena in graphene based 2D heterostructures. Lifshitz transition in bilayer graphene (BLG) arising from trigonal warping has been established theoretically and experimentally. Nevertheless, the experimental realization of its effects on the transport properties has been challenging because of its relatively low energy scale ($\sim 1$ meV). In this work, we demonstrate that the thermoelectric power (TEP) can be used as an effective probe to investigate fine changes in the DOS of BLG. We observe additional entropy features in the vicinity of the charge neutrality point (CNP) in gapped BLG. This apparent violation of Mott formula can be explained quantitatively by considering the effects of trigonal warping, thereby serving as a possible evidence of a Lifshitz transition.
Evaluating Marxan as a terrestrial conservation planning tool

description: A variety of reserve design software programs are available to assist in the selection and spatial configuration of new protected areas. One such application, Marxan, produces spatially cohesive reserve configurations which meet representation targets efficiently. Conservation agencies worldwide are adopting Marxan as a conservation planning tool, however it is not currently used by Parks Canada when conducting feasibility studies for potential national park reserves. This thesis evaluates whether Marxan could be a useful decision-support tool for Parks Canada to use when selecting and designing potential park areas. The assessment is based on four usability criteria and three park selection criteria, developed in consultation with Parks Canada. Concurrent with this thesis, Parks Canada is conducting a feasibility study for a national park reserve in the South Okanagan-Lower Similkameen region of British Columbia, Canada. This region serves as a case study for the thesis. Marxan was used to create 36 unique reserve configuration options for the case study area and to help evaluate the performance of each reserve. Overall, Marxan fully satisfied three criteria, partially satisfied three, and failed to meet one. This study demonstrates that Marxan provides a useful means to design and explore a range of representative and scientifically defensible reserves. However, to use it effectively requires technical and ecological expertise, a comprehensive GIS infrastructure, good data and time. This analysis concludes that Marxan would be a very appropriate tool to assist Parks Canada in selecting and designing potential national park reserves. Marxan would be best used in conjunction with other decision-support tools, expert knowledge and public consultation.

description: The discovery of two-dimensional (2D) materials possessing switchable spontaneous polarization with atomic thickness opens up exciting opportunities to realize ultrathin, high-density electronic devices with potential applications ranging from memories and sensors to photocatalysis and solar cells. First-principles methods based on density functional theory (DFT) have facilitated the discovery and design of 2D ferroelectrics (FEs). However, DFT calculations employing local and semilocal exchange-correlation functionals failed to predict accurately the band gaps for this family of low-dimensional materials. Here, we present a DFT+$U$+$V$ study on 2D FEs represented by single-layer $α$-In$_2$Se$_3$ and its homologous III$_2$-VI$_3$ compounds with both out-of-plane and in-plane polarization, using Hubbard parameters computed from first-principles. We find that ACBN0, a pseudo-hybrid density functional that allows self-consistent determination of $U$ parameters, improves the prediction of band gaps for all investigated 2D FEs with a computational cost much lower than the hybrid density functional. The inter-site Coulomb interaction $V$ becomes critical for accurate descriptions of the electronic structures of van der Waals heterostructures such as bilayer In$_2$Se$_3$ and In$_2$Se$_3$/InTe. Pertinent to the study of FE-based catalysis, we find that the application of self-consistent $U$ corrections can strongly affect the adsorption energies of open-shell molecules on the polar surfaces of 2D FEs.

description: Recognizing raaga emotions from speech has gained immense attention recently. With the increasing demand for human computer interaction, it is necessary to understand the raaga emotional state of the singer. In this paper an attempt has been made to recognize and classify the raaga emotions from singers Database. Here the classification is mainly based on extracting several key features like Mel Frequency Cepstral Coefficients (MFCCs) from the speech signals of those persons by using the process of feature extraction. For training and testing of the method, data collection is carried out in Andhra Pradesh, India. It consisted of acted speeches of one short raaga, emotionally biased sentence repeated 5 times with different states by 52 melakartha raagas for training and another 20 melakartha raagas for testing. The experiments were performed pertaining to singer raagas. Using a statistical model like Gaussian Mixture Model classifier (GMM) and features extracted from these speech signals. We build a unique identity for each raaga emotion that enrolled for raaga emotion recognition. Expectation and Maximization (EM) algorithm, an elegant and powerful method is used with latent variables for finding the maximum likelihood solution, to test the other raaga emotions against the database of all melakartha raagas in the database.
