description: Feedback from AGN is thought to be key in shaping the life cycle of their host galaxies by regulating star-formation activity. Therefore, to understand the impact of AGN on star formation, it is essential to trace the molecular gas out of which stars form. In this paper we present the first systematic study of the CO properties of AGN hosts at z~2 for a sample of 27 X-ray selected AGN spanning two orders of magnitude in AGN bolometric luminosity (Lbol= 10^44.7-10^46.9 erg/s) by using ALMA Band 3 observations of the CO(3-2) transition (~1" angular resolution). To search for evidence of AGN feedback on the CO properties of the host galaxies, we compared our AGN with a sample of inactive (i.e., non-AGN) galaxies from the PHIBSS survey with similar redshift, stellar masses, and SFRs. We used the same CO transition as a consistent proxy for the gas mass for the two samples in order to avoid systematics involved when assuming conversion factors. By adopting a Bayesian approach to take upper limits into account, we analyzed CO luminosities as a function of stellar masses and SFRs, as well as the ratio LCO(3-2)/M* (proxy for the gas fraction). The two samples show statistically consistent trends in the LCO(3-2)-Lfir and LCO(3-2)-M* planes. However, there are indications that AGN feature lower CO(3-2) luminosities (0.4-0.7 dex) than inactive galaxies at the 2-3sigma level when we focus on the subset of parameters where the results are better constrained and on the distribution of the mean LCO(3-2)/M*. Therefore, even by conservatively assuming the same excitation factor r31, we would find lower molecular gas masses in AGN, and assuming higher r31 would exacerbate this difference. We interpret our result as a hint of the potential effect of AGN activity (e.g., radiation and outflows), which may be able to heat, excite, dissociate, and/or deplete the gas reservoir of the host galaxies.

description: The ongoing archaeological research at the ancient site of Gadara, Jordan, conducted jointly with the Department of Antiquities of Jordan has set its ­focus in the last years to the hilltop, the area of the upper village of Umm Qays, called Hara Foqa. The report presents an overview on the activities done in the last years with focus on a building-complex, probably destroyed by the earthquake in 749 CE. Its embedding into a broader context gives a first insight into the ­settlement history and development at the highest point of the ancient town. It shows the potential of an area that was left in Umayyad times and resettled more than thousand years later, when families started building their houses there again.
Thermal nature of de Sitter spacetime and spontaneous excitation of atoms

description: We consider, in de Sitter spacetime, both freely falling and static two-level atoms in interaction with a conformally coupled massless scalar field in the de Sitter-invariant vacuum, and separately calculate the contributions of vacuum fluctuations and radiation reaction to the atom's spontaneous excitation rate. We find that spontaneous excitations occur even for the freely falling atom as if there is a thermal bath of radiation at the Gibbons-Hawking temperature and we thus recover, in a different physical context, the results of Gibbons and Hawking that reveals the thermal nature of de Sitter spacetime. Similarly, for the case of the static atom, our results show that the atom also perceives a thermal bath which now arises as a result of the intrinsic thermal nature of de Sitter spacetime and the Unruh effect associated with the inherent acceleration of the atom.

description: We evaluate the exact dipole coupling strength between a single emitter and the radiation field within an optical cavity, taking into account the effects of multilayer dielectric mirrors. Our model allows one to freely vary the resonance frequency of the cavity, the frequency of light or atomic transition addressing it and the design wavelength of the dielectric mirror. The coupling strength is derived for an open system with unbound frequency modes. For very short cavities, the effective length used to determine their mode volume and the lengths defining their resonances are different, and also found to diverge appreciably from their geometric length, with the radiation field being strongest within the dielectric mirror itself. Only for cavities much longer than their resonant wavelength does the mode volume asymptotically approach that normally assumed from their geometric length.

description: Using a chiral random matrix theory we can now derive the low energy partition functions and Dirac eigenvalue correlations of QCD with different chemical potentials for the dynamical and valence quarks. The results can also be extended to complex (and purely imaginary) chemical potential. We also discuss possible applications such as fitting to low energy constants and understanding the phase diagrams of the full and partially quenched theories.

description: We present the analysis of the diffuse, low column density HI environment of 18 MHONGOOSE galaxies. We obtained deep observations with the Robert C. Byrd Green Bank Telescope, and reached down to a 3sigma column density detection limit of NHI=6.3x10^{17} cm^{-2} over a 20 km/s linewidth. We analyze the environment around these galaxies, with a focus on HI gas that reaches column densities below NHI=10^{19} cm^{-2}. We calculate the total amount of HI gas in and around the galaxies revealing that nearly all of these galaxies contained excess HI outside of their disks. We quantify the amount of diffuse gas in the maps of each galaxy, defined by HI gas with column densities below 10^{19} cm^{-2}, and find a large spread in percentages of diffuse gas. However, by binning the percentage of diffuse HI into quarters, we find that the bin with the largest number of galaxies is the lowest quartile (0-25\% diffuse HI). We identified several galaxies which may be undergoing gas accretion onto the galaxy disk using multiple methods of analysis, including azimuthally averaging column densities beyond the disk, and identifying structure within our integrated intensity (Moment 0) maps. We measured HI mass outside the disks of most of our galaxies, with rising cumulative flux even at large radii. We also find a strong correlation between the fraction of diffuse gas in a galaxy and its baryonic mass, and test this correlation using both Spearman and Pearson correlation coefficients. We see evidence of a dark matter halo mass threshold of M_{halo}~10^{11.1} \msun{} in which galaxies with high fractions of diffuse HI all reside below. It is in this regime in which cold-mode accretion should dominate. Finally, we suggest a rotation velocity of v_{rot}~80 km\s as an upper threshold to find diffuse gas-dominated galaxies.

description: Using the twistor correspondence, this article gives a one-to-one correspondence between germs of toric anti-self-dual conformal classes and certain holomorphic data determined by the induced action on twistor space. Recovering the metric from the holomorphic data leads to the classical problem of prescribing the Cech coboundary of 0-cochains on an elliptic curve covered by two annuli. The classes admitting Kahler representatives are described; each such class contains a circle of Kahler metrics. This gives new local examples of scalar-flat Kahler surfaces and generalises work of Joyce who considered the case where the distribution orthogonal to the torus action is integrable.

description: Malleable food preferences of the tobacco hornworm (larval Manduca sexta) have been the focus of decades of investigation.  These previous studies have described the behavioral changes as an induction of oligophagy or as an induction of preference, both of which predict diet-induced changes in food selection but differ in the scope and mechanism associated with those changes.  This project attempts to apply novel bioassays and comparisons to a seasoned topic, and in doing so add to our understanding regarding diet experience and food palatability in M. sexta. Larvae tested using a no-choice disc or no-choice emigration assay displayed an inherently high acceptability for solanaceous plants.  These larvae also displayed varied, diet-dependent acceptabilities for non-solanaceous foods.  Evidence for inductions of preference and inductions of specificity were observed in non-solanaceous-reared larvae.  Similar changes in preference were also described for solanaceous-reared larvae tested in 2-choice and 3-choice assays.  The data discussed supports both diet-induced changes in the palability of a rearing plant, as well as related plants, but does not support induced oligophagy.  Suggestions regarding future studies and terminology included.

description: The Palatine in Rome has a very long and well-documented history of ­research. However, there is no systematic compilation of the images produced during its exploration. With the help of a research grant (Santoro), ­extensive materials were collected for its exploration in the 19th century. The images researched in the process are available for inclusion in a geoinformation system on the Palatine (»PalatinGIS«). The GIS serves as a working tool for a study on the visualisation history of the Palatine (Sielhorst). In this ­article, the role of five images of the Palatine is explained in more detail by briefly describing them and placing them in their context in terms of the ­history of media and ideas.

description: We develop an approach to calculate the admittance of effectively one-dimensional open quantum systems in random phase approximation. The stationary, unperturbed system is described within the Landauer-Büttiker formalism taking into account the Coulomb interaction in the Hartree approximation. The dynamic changes in the effective potential are calculated microscopically from the charge-charge correlation function resulting from the stationary scattering states. We provide explicit RPA-expressions for the quantum admittance. As a first example the case of a quantum capacitor is considered where we can derive a small-frequency expansion for the admittance which lends itself to an experimental testing of the theory. A comparison of the low-frequency expansion with the complete RPA-expression shows that for a quantum capacitor a simple classical equivalent circuit with frequency-independent elements does not describe satisfactorily the quantum-admittance with increasing the frequency.

Context Awareness

description: Smart phones and other mobile devices have a simple notion of context largely restricted to temporal and spatial coordinates. Service providers and enterprise administrators can deploy systems incorporating activity and relations context to enhance the user experience, but this raises considerable collaboration, trust and privacy issues between different service providers. Our work is an initial step toward enabling devices themselves to represent, acquire and use a richer notion of context that includes functional and social aspects such as co-located social organizations, nearby devices and people, typical and inferred activities, and the roles people fill in them. We describe a system that learns to recognize richer contexts using sensor data from a person's Android phone along with annotations on her calendar and general background knowledge. Classifier models predict the individual users' context with respect to a mid-level detailed activity he is performing like `Listening a Talk', `Walking', `Sleeping', etc. We report on an evaluation of the individual and generic models in the University setting for predicting context.

description: We formulate the ten-dimensional super-Yang-Mills theory in a twisted superspace with 8+1 supercharges. Its constraints do not imply the equations of motion and we solve them. As a preliminary step for a complete formulation in a twisted superspace, we give a superspace path-integral formulation of the N=2, d=4 super-Yang-Mills theory without matter. The action is the sum of a Chern--Simons term depending on a super-connection plus a BF-like term. The integration over the superfield B implements the twisted superspace constraints on the super-gauge field, and the Chern-Simons action reduces to the known action in components.

description: The last few years has seen an enormous growth in the usage of smart phones. This trend is expected to continue in the near future as well with the availability of more processing power and larger form factors. This explosive growth has contributed to an unprecedented adoption of mobile data services which results in severe network congestion during peak hours due to limited availability of cellular capacity and the prohibitive cost of installing new infrastructure.  Even the recent adoption of Long Term Evolution (LTE) by carriers has not kept pace with increasing data needs and the networks continue to be under stress. However, it is of utmost importance for the provider to maintain superior Quality of Experience (QoE) and Quality of Service (QoS) even under constrained network capacity. One possible approach for achieving high QoE is through the use of context information from smart phones that allow the network to take pro-active decisions for content delivery.  Key players within the telecommunication industry seem to be unanimous in foreseeing, for the next few years that the Machine-to-Machine (M2M) traffic trends will grow rapidly. The Applications on mobiles, serving content, can be considered the present manifestation of the growing trend. Understanding the potential impact of M2M traffic on current network dimensioning and architectures is of paramount importance for the success and sustainability of these novel services in future wireless mobile networks. This thesis presents a tool ""Melange"" which can be used to measure and demonstrate the benefits of using context awareness for content delivery. Using the tool, the user can remotely control a number of mobile handsets by deploying different types of synthetic and natural workloads, emulating the traffic, to evaluate the impact on battery consumption and user perception of context-aware content pre-fetching.

description: У контексті європейської інтеграції та виконання Угоди про асоціацію між Україною та ЄС, одним з найбільш актуальних питань українського суспільства є правове регулювання процедурних відносин між органами виконавчої влади та органами місцевого самоврядування з фізичними та юридичними особами. Адміністративні послуги представляють собою систему взаємовідносин між державою (включаючи органи влади, державні установи, організації, підприємства) та суспільством, в межах яких держава задовольняє потреби громадян через виконання своїх завдань і реалізацію функцій. Світова практика регулювання системи адміністративних послуг, що охоплює їх формування та вдосконалення, базується на розробці відповідної законодавчої бази. Первинність правотворчих процедур гарантує визначення загальних принципів діяльності органів виконавчої влади у наданні послуг населенню, включаючи стандарти якості їх надання. Чітке і зрозуміле законодавче визначення порядку надання адміністративних послуг є одним з ключових принципів ефективного функціонування адміністративного управління, який визнаний у міжнародній практиці, вимагає аналізу нормативного забезпечення системи адміністративних послуг в Україні, оскільки підвищення ефективності адміністративного управління в Україні можливе через вдосконалення механізмів надання адміністративних послуг. Метою дослідження є виявлення особливостей нормативно-правового забезпечення надання адміністративних послуг в Україні. Для цього необхідно проаналізувати існуючу нормативну базу та визначити потенційні шляхи удосконалення законодавства у сфері надання адміністративних послуг. Стаття містить результати дослідження нормативно-правових механізмів, що спрямовані на регулювання діяльності органів виконавчої влади та органів місцевого самоврядування на регіональному рівні у системі надання адміністративних послуг. Досліджено основну проблематику правового регулювання процесів надання адміністративних послуг, визначено певні недоліки та розроблено пропозиції щодо шляхів їх вирішення.

description: Several exclusive $B_s^0$ decays are studied using a 1.86 fb-1 data sample collected at the Y(5S) resonance with the Belle detector at the KEKB asymmetric energy e^+ e^- collider. In the $B_s^0 \to D_s^- π^+$ decay mode we find 10 $B_s^0$ candidates and measure the corresponding branching fraction. Combining the B_s^0 -> D_s^{(*)-} π^+, B_s^0 -> D_s^{(*)-} ρ^+, B_s^0 -> J/ψϕand B_s^0 -> J/ψηdecay modes, a significant $B_s^0$ signal is observed. The ratio σ(e^+ e^- -> B_s^* \bar{B}_s^*) / σ(e^+ e^- -> B_s^{(*)} \bar{B}_s^{(*)}) = (93^{+7}_{-9} \pm 1)% is obtained at the Y(5S) energy, indicating that $B_s^0$ meson production proceeds predominantly through the creation of $B^*_s \bar{B}^*_s$ pairs. The $B_s^0$ and $B_s^*$ meson masses are measured to be M(B_s^0)=(5370 \pm 1 \pm 3)MeV/c^2 and M(B_s^*)=(5418 \pm 1 \pm 3)MeV/c^2. Upper limits on the B_s^0 -> γγ, B_s^0 -> ϕγ, B_s^0 -> K^+ K^- and B_s^0 -> D_s^{(*)+} D_s^{(*)-} branching fractions are also reported.

description: BaFe$_2$S$_3$ is a quasi-one-dimensional antiferromagnetic insulator that becomes superconducting under hydrostatic pressure. The magnetic ordering temperature, $T_N$, as well as the presence of superconductivity have been found to be sample dependent. It has been argued that the Fe content may play a decisive role, with the use of 5%mol excess Fe being reportedly required during the synthesis to optimize the magnetic ordering temperature and the superconducting properties. However, it is yet unclear whether an Fe off-stoichiometry is actually present in the samples, and how it affects the structural, magnetic and transport properties. Here, we present a systematic study of compositional, structural and physical properties of BaFe$_{2+δ}$S$_3$ as a function of the nominal Fe excess $δ$. As $δ$ increases, we observe the presence of an increasing fraction of secondary phases but no systematic change in the composition or crystal structure of the main phase. Magnetic susceptibility curves are influenced by the presence of magnetic secondary phases. The previously reported maximum of $T_N$ at $δ$=0.1 was not confirmed. Samples with nominal $δ$=0 present the lowest $T_N$ and the resistivity anomaly at the highest temperature $T^*$ while, for $δ\geq 0.05$, both quantities and the transport gap are seemingly $δ$-independent. Finally, we show that crystals free of ferromagnetic spurious phases can be obtained by remelting samples with nominal $δ$=0.05 in a Bridgman process.

description: The small Hellenistic sanctuary at Vau i Dejës (Northern Albania) was discovered in only 2015. The small village is located in the northeast of the Zadrima plain which extends between the modern cities of Shkodra and Lezha, formerly the ancient poleis of Skodra and Lissos. The site which is situated on a hill is marked by a rugged rock surface. The remarkably rich finds consist chiefly of sherds from fine Hellenistic ceramics and further of terracotta fragments from a female deity as well as Hellenistic coins and metal objects. In addition, there were some vessel fragments and coins from the period of Late Antiquity. Not one single object could be attributed to the Roman Period (1st–3rd centuries AD).

description: We use the formulation of the quantum mechanics of first quantized Klein-Gordon fields given in the first of this series of papers to study relativistic coherent states. In particular, we offer an explicit construction of coherent states for both charged and neutral (real) free Klein-Gordon fields as well as for charged fields interacting with a constant magnetic field. Our construction is free from the problems associated with charge-superselection rule that complicated the previous studies. We compute various physical quantities associated with our coherent states and present a detailed investigation of their classical (nonquantum) and nonrelativistic limits.

description: We describe a QCD based model which incorporates the main properties of the inclusive particle distributions expected for diffractive processes, including the diffractive dissociation at high energies. We study, in turn, the total cross section, $σ_{tot}$, the differential elastic, $dσ_{el}/dt$, cross section, the dependence of the single proton dissociation cross section, $ξd^{SD}/dξ$, on the momentum fraction, $ξ= 1-x_L$, lost by the leading proton, the multiplicity distributions in inelastic (non-diffractive) collisions and in the processes of dissociation. Besides this we calculate the mean transverse momenta of the `wee partons' (secondaries) produced in the case of dissociation (that is in the processes with a large rapidity gap) and compare it with that in inelastic interactions.

description: During a six-month DAI research grant from the Istanbul Department, the documentary material of the old excavations at Musalla Mezarlığı in ­ancient Pergamon, located in the Pergamon Archives, was newly recorded and examined with regard to its scientific informative value. From records already inserted into the iDAI.field database, an attempt was also made to obtain a quantitative overview of the excavations' excavated find material. The project served as preparation for a larger study possibly a ­dissertation, on the settlement and research history of the Musalla Mezarlığı and its find material. Due to the global pandemic, the project was worked on from home office.
The grandmother stories : oral tradition and the transmission of culture
Creators: name: Sterling, Shirley
Publisher: name: University of British Columbia
Year: 2009

description: The grandmother stories explore the meaningfulness of two Nlakapamux oral traditions, speta'kl (creation stories) and spilaxem (personal narratives), which are both study subject and study method and the methodology which drives the research. Each of a series of linked critical essays begins with a grandmother story and then provides an analysis of what the story explicates in terms of personal meaningfulness and contemporary educational theory and practice. The purpose is to examine how oral traditions have survived among the Nlakapamux of the Interior Salish of British Columbia and through transmission provide pedagogies, philosophies, histories and healing. Oral traditions are one of the most lasting methods of Nlakapamux education, and they can inform educators and restore cultural relevance to what and how we teach Nlakapamux children and other learners in the classroom today.

description: We implement a photon-counting Optical Time Domain Reflectometer (OTDR) at 1.55um which exhibits a high 2-point resolution and a high accuracy. It is based on a low temporal-jitter photon-counting module at 1.55um. This detector is composed of a periodically poled Lithium niobate (PPLN) waveguide, which provides a wavelength conversion from near infrared to visible light, and a low jitter silicon photon-counting detector. With this apparatus, we obtain centimetre resolution over a measurement range of tens of kilometres.

description: The current Internet was originally designed to provide ``best- effort'' data transport over a wired infrastructure with end hosts utilizing a layered network stack to provide reliability, quality of service, security etc. for user applications. However, the proliferation of inelastic applications, coupled with wide spread migration towards hybrid networks utilizing wired and wireless links and the plethora of end host variants ranging from cell phones to enterprise servers necessitates the migration of more and more services away from the edges and into the network. This dissertation presents a generic and flexible framework that will enable the incremental deployment of intelligent services into the network with the aim of optimizing the end-user experience for networked applications. Our framework relies on using semantic tags embedded in the data stream that describe the type of content carried in stream and levels of service desired. The nodes in the network utilize this semantic markup to reason over the stream to identify the set of actions that need to be performed based on the policies specified. We present the results of employing our framework to various scenarios including cross layer optimization for Ultra wideband PANs, use of semantic tags to differentiate traffic into service classes and utilizing the framework to allow BGP to employ security and trust relationships in the route decision process. In addition to the development of the framework, we have also developed a network ontology that can be used to both model traffic flows and their service needs along with network topology and state. The framework employs multi-level reasoning that utilizes the meta-data carried in the streams coupled with external contextual information to determine the set of actions that need to be performed to the datastream in-transit. This reasoning is done using network policies specified by network administrators using our rule language that is easy to use, human readable and machine understandable, non-network protocol specific, and can be formally verified for consistency.

description: The $k$-essence modified $f(R)$ gravity model, i.e., $f(R,ϕ,X)$ theory is studied. The question of violation of causality, in the framework of Gödel-type universes, is investigated in this gravitational model. Causal and non-causal solutions are allowed. A critical radius for non-causal solution is calculated. It is shown that the violation of causality depends on the content of matter.

description: Constrained by the low energy density of Lithium-ion batteries with all-electric aircraft propulsion, hybrid-electric aircraft propulsion drive becomes one of the most promising technologies in aviation electrification, especially for wide-body airplanes. In this thesis, a three-port triple active bridge (TAB) DC-DC converter is developed to manage the power flow between the turbo generator, battery, and the propulsion motor. The TAB converter is modeled based on the emerging Silicon Carbide (SiC) Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) modules operating at high switching frequency, so the size of the magnetic transformer can be significantly reduced. Different operation modes of this hybrid-electric propulsion drive based on the SiC TAB converter are modeled and simulated to replicate the takeoff mode, cruising mode, and regenerative charging mode of a typical flight profile. Additionally, soft switching is investigated for the TAB converter to further improve the efficiency and power density of the converter, and zero voltage switching is achieved at heavy load operating conditions. The results show that the proposed TAB converter is capable of achieving high efficiency during all stages of the flight profile.

description: (ABRIDGED) The Gamma-ray Large Area Space Telescope (GLAST) will measure the spectra of distant extragalactic sources of high energy gamma-rays. GLAST can look for energy dependent propagation effects from such sources as a signal of Lorentz invariance violation (LIV). Such sources should also exhibit high energy spectral cutoffs from pair production interactions with low energy photons. The properties of such cutoffs can also be used to test LIV. Detectors to measure gamma-ray polarization can look for the depolarizing effect of space-time birefingence predicted by loop quantum gravity. A spaceborne detector array looking down on Earth to study extensive air showers produced by ultrahigh energy cosmic rays can study their spectral properties and look for a possible deviation from the predicted GZK effect as another signal of LIV.

description: To support corporate business' competition on speed to market for product and service development, generically modeled data structures have been used in the development of vertical application software systems, and in storing XML and RDF data for its flexibility, adaptability, and agility. However, generic data models require multiple self-joins on a single table with a large volume of data, causing slow performance for business intelligence (BI) applications. Conversely, traditional specific data models have faster performance but are not flexible, adaptive, or agile for speed to market. A generic data model named the Class Object Value Element Relationship (COVER) model was developed for storing node-oriented tree data information, and is suitable for automated pivot index generation and distributed data processing. This approach utilizes pivot view with appropriate metadata constructs to expose the search predicate fields for indexing, leading to performance gains in data retrieval for queries on branches or leaves across multiple trees. It is beneficial for production support or data retrieval to feed business intelligence and data mining.  A distributed COVER model with two different physical implementation variations was also developed for implementation on the distributed and parallel cloud computing platforms to take the scalability and performance advantages of the technology.  Benchmark experiments for comparing the query performance on the COVER model against self-join and XPath/XQuery approaches using RDBMS were executed and proved that the COVER model outperforms the other two on the same sets of test data queries. Furthermore, benchmark experiments on distributed cloud computing environment were conducted using Hadoop HBase for comparing the RDBMS COVER and distributed COVER models. The results have shown that the distributed COVER models outperformed the RDBMS and demonstrated that the distributed COVER model is a viable data storage approach for flexible, adaptable, agile, and scalable   systems.

description: Results of a study of the $K^+ \rightarrow π^{0} e^{+} νγ$ decay at OKA setup are presented. More than 32000 events of this decay are observed. The differential spectra over the photon energy and the photon-electron opening angle in kaon rest frame are presented. The branching ratios, normalized to that of $K_{e3}$ decay are calculated for different cuts in $E^*_γ$ and $cosΘ^{*}_{eγ}$. In particular, the branching ratio for $E^{*}_γ>30$ MeV and $Θ^{*}_{e γ}>20^{\circ}$ is measured R = $\frac{Br(K^+ \rightarrow π^{0} e^{+} ν_{e} γ) } {Br(K^+ \rightarrow π^{0} e^{+} ν_{e})} $ = =(0.587$\pm$0.010($stat.$)$\pm$0.015($syst.$))$\times10^{-2}$, which is in a good agreement with ChPT $O(p^{4})$ calculations.
