description: We propose a scheme for classifying the entanglement of a tripartite pure qubit state. This classification scheme consists of an ordered list of seven elements. These elements are the Cayley hyper-determinant, and its six associated $2 \times 2$ subdeterminants. In particular we show that this classification provides a necessary and sufficient condition for separability.

description: In 2000 July/August a microlensing event occurred at a distance of 2.33 arcmin from the center of the globular cluster M22 (NGC6656), observed against the dense stellar field of the Milky Way bulge. We have used the adaptive optics system NACO at the ESO Very Large Telescope to resolve the two objects that participated in the event: the lens and the source. The position of the objects measured in 2011 July is in agreement with the observed relative proper motion of M22 with respect to the background bulge stars. Based on the brightness of the microlens components we find that the source is a solar-type star located at a distance of 6.0 +/-1.5 kpc in the bulge, while the lens is a 0.18 +/-0.01 Msun dwarf member of the globular cluster located at the known distance of 3.2 +/-0.2 kpc from the Sun.

description: Grazing Incidence Neutron Spin Echo Spectroscopy (GINSES) opens new possibilities for observing the thermally driven dynamics of macromolecules close to a rigid interface. The information about the dynamics can be retrieved as a function of scattering depth of the evanescent neutron wave, on the length scale in the range of some 10-100 nm. Using a classical neutron spin echo spectrometer with a laterally collimated beam, dynamics can be measured in grazing incidence geometry. We show examples of how the interface modifies the dynamics of microemulsions, membranes and microgels. Instrumental details and possible improvements for this technique will be presented. The key issue is the low intensity for dynamics measurements with an evanescent neutron wave. Conceptual questions how a specialised instrument could improve the experimental technique will be discussed.

description: A wireless sensor network has a wide application domain which is expanding everyday and they have been deployed pertaining to their application area. An application independent approach is yet to come to terms with the ongoing exploitation of the WSNs. In this paper we propose a decentralized lifetime maximizing tree for application independent data aggregation scheme using the clustering for data delivery in WSNs. The proposed tree will minimize the energy consumption which has been a resisting factor in the smooth working of WSNs as well as minimize the distance between the communicating nodes under the control of a sub-sink which further communicate and transfer data to the sink node.

description: Most of the existing DENV entry inhibitors were discovered through structure-based, high-throughput screening techniques and optimization approaches by aiming β-OG pocket. However, the class of precise chemical scaffolds with superior antiviral activity targeting the early stages of virus infection that is considered to be beneficial in therapeutics and is still in process. In this study, ligand-based pharmacophore modeling using existing DENV entry inhibitors provided two best models, AADRR-2 and AAADR-2 (A- accepter, D- donor, R-ring) to screen public and DrugBank datasets. Further, approximately 36000 molecules were filtered using Zinc13 by employing the ideal validated models. Additionally, using β-OG binding pocket as target site, molecular docking experiments including induced-fit studies were conducted that provided further structurally divergent ligands. Moreover, the refined list of preferential hits were filtered out based on the best fitness score, binding energy and interaction paradigm, among them fused pyrimidine, hydrazone and biphenyl core comprising scaffolds were identified possessing profound interaction profile with key amino acid residues, ALA-50, GLN-200, PHE-193 and PHE-279 in 100 ns MD simulations. Additionally, the search for similar chemical fingerprints from DrugBank library was also carried out and Eltrombopag (Promacta/Revolade® prescribed in thrombocytopenia) was identified as a preferential β-OG pocket binder. The identified pyrazole-based hydrazone class of drug, Eltrombopag is in phase II clinical trials employed to treat dengue-mediated thrombocytopenia. Communicated by Ramaswamy H. Sarma

A field investigation characterizing the hyporheic zone of a tidally-influenced river
Creators: name: Bianchin, Mario Sergio
Publisher: name: University of British Columbia
Year: 2010

description: This research investigated groundwater surface water interaction (GWSi) of the Fraser River, in the Lower Mainland of British Columbia. At the Braid Street site, GPR, seismic reflection surveys, bulk resistivity profiling, and sediment sampling were used to map the sediments of the riverbed and the area of contaminated groundwater discharge. Groundwater profiling revealed that three water types occur within the upper 2 m of the riverbed sediments a result of mixing of river water, contaminated (fresh) groundwater, and saline groundwater. The distribution of groundwater solutes indicate that during a single tidal cycle, river water penetrates the riverbed to a depth of approximately 15 cm but the long term effects of tidal pumping of river water into the riverbed is observed to a depth of approximately 1 meter below river bed (m.b.r.b.) Temperature measurements coupled with independent hydraulic head measurements within the riverbed confirmed that GWSi under tidal forcing produced a 1 m-deep hyporheic zone (HZ). Time-averaged riverbed temperature profiles displayed a distinct compressed convex-upward pattern, clear evidence of net groundwater discharge. However, the instantaneous time series data indicate that riverbed temperatures, to a depth of 1 m were affected by tidal-forcing. Heat transport modeling revealed that instantaneous velocities within the shallow sediments of the riverbed are rather high during either a flooding or ebbing tide. Further, the magnitude of the tidally-induced pressure gradient was found to be significantly greater than the pressure gradient attributable to flow across large river bottom bedforms, indicating that bedform-driven exchange is limited to within a few centimeters beneath the riverbed. At the Kidd2 site, where saline encroachment occurs up river, hyporheic and hypoaigic (recharge by saline water) processes occur. During low winter river flows saline encroachment up river occurs and hypoaigic exchange dominates. During low tide the saline water is pushed out of the river and hyporheic exchange dominates. Hyporheic exchange dominates exchange during freshet leading to deep freshening of the aquifer on the order of 2+ m.

description: Sympathetic cooling of trapped ions has become an indispensable tool for quantum information processing and precision spectroscopy. In the simplest situation a single Doppler-cooled ion sympathetically cools another ion which typically has a different mass. We analytically investigate the effect of the mass ratio of such an ion crystal on the achievable temperature limit in the presence of external heating. As an example, we show that cooling of a single Al+ with Be+, Mg+ and Ca+ ions provides similar results for heating rates typically observed in ion traps, whereas cooling ions with a larger mass perform worse. Furthermore, we present numerical simulation results of the rethermalisation dynamics after a background gas collision for the Al+/Ca+ crystal for different cooling laser configurations.

description: Understanding defect-phonon interactions in solid-state devices is crucial for improving our current knowledge of quantum platforms. In this work, we develop first-principles calculations for a defect composed of two spin-$1/2$ particles that interact with phonon modes in a one-dimensional lattice. We follow a bottom-up approach that begins with a dipolar magnetic interaction to ultimately derive the spectral density function and time-local master equation that describes the open dynamics of the defect. We provide theoretical and numerical analysis for the non-Markovian features of the defect-phonon dynamics induced by a pure dephasing channel acting on the Bell basis. Finally, we analyze two measures of non-Markovianity based on the canonical rates and Coherence, shedding more light on the role of the spectral density function and temperature; and envisioning experimental realizations.

description: We discuss the physics prospects of photon-induced measurements using the high-granularity FoCal detector to be installed at the ALICE experiment, covering the pseudorapidity interval $3.4 \leq η\leq 5.8$. This new detector, scheduled to be in operation from Run 4, will explore the small Bjorken-$x$ physics region in an unprecedented way. In this region the gluon saturation phenomenon is expected to be dominant. Combined with the rest of the ALICE subdetectors, including the zero degree calorimenters, FoCal will serve to reconstruct in a model-independent way the measured photoproduction cross sections for vectors mesons in a wide range of photon-target energies, down to $x$ values of about $7\times 10^{-6}$ and $2\times 10^{-6}$ in ultra-peripheral photon--proton and photon--lead collisions, respectively.

description: The octanol-water partition coefficient of 1,2-dipalmitoyl-sn-glycero-3-phosphatidylcholine (DPPC) was investigated using atomistic molecular dynamics simulations via thermodynamic integration and multistate Bennett acceptance ratio methods. The GAFF and CHARMM36 force fields were used with six water models widely used in molecular dynamics simulations. The OPC4 water model provided the best agreement with the experimental octanol-water partition coefficient of DPPC using the two force fields. However, there is still plenty of room for improvement in water models with correct estimation of surface tension that uses better and suitable non-bonded interaction parameters between water-water and water-DPPC. The Gibbs free energy of transferring DPPC from octanol to water phase was calculated to be 19.8 ± 0.3 and 20.2 ± 0.3 kcal mol−1, giving a partition coefficient of 14.5 ± 0.4 and 14.8 ± 0.3 for the GAFF and CHARMM36 force fields, respectively. This study reinforces the importance of developing new water models that reproduce experimental surface tensions to reconcile the water-water and water-DPPC non-bonded interactions and the existing discrepancy between experimental measurements of amphiphilic molecules that are important in many areas of scientific applications and industry such as biophysics, surfactant, colloids, membranes, medicine, nanotechnology, and food and pharmaceutical industries, and so on. It raises two important open questions: Is the experimental octanol-water partition coefficient of DPPC reliable? Or is its calculation accurate using the OPC4 water model? With respect to the experimental measurements, there may be non-treated aspects such as the formation of aggregates in aqueous phase and limit of detection of the applied method. And, in the calculation, some effects are not possible to be considered in a correct way or viable time such as calculating quantum effects, sampling all conformations, considering phase transitions, and correctly evaluating the intermolecular forces to estimate an accurate surface tension.

description: We present two-dimensional hydrodynamical simulations of the tidal interaction between a supermassive black hole binary with moderate mass ratio, and the fossil gas disc where it is embedded. Our study extends previous one-dimensional height-integrated disc models, which predicted that the density of the gas disc between the primary and the secondary black holes should rise significantly during the ultimate stages of the binary's hardening driven by the gravitational radiation torque. This snow-plough mechanism, as we call it, would lead to an increase in the bolometric luminosity of the system prior to the binary merger, which could be detected in conjunction with the gravitational wave signal. We argue here that the snow-plough mechanism is unlikely to occur. In two-dimensions, when the binary's hardening timescale driven by gravitational radiation becomes shorter than the disc's viscous drift timescale, fluid elements in the inner disc get funneled to the outer disc through horseshoe trajectories with respect to the secondary. Mass leakage across the secondary's gap is thus found to be effective and, as a result, the predicted accretion disc luminosity will remain at roughly the same level prior to merger.

description: In quantum computing, the quantum walk search algorithm is designed for locating fixed marked nodes within a graph. However, when multiple marked nodes exist, the conventional search algorithm lacks the capacity to simultaneously amplify the marked nodes as well as identify the correct chronological ordering between the marked nodes, if any. To address this limitation, we explore a potential extension of the algorithm by introducing additional quantum states to label the marked nodes. The labels resolve the ambiguity of simultaneous amplification of the marked nodes. Additionally, by associating the label states with a chronological ordering, we can extend the algorithm to track a moving particle on a two-dimensional surface. Our algorithm efficiently searches for the trajectory of the particle and is supported by a proposed quantum circuit. This concept holds promise for a range of applications, from real-time object tracking to network management and routing.

description: In the present paper, the effect of the Vadasz inertia term on the onset of convective motions for a Darcy-Brinkman model is investigated. It is proved that this term leads to the possibility for oscillatory convection to occur. Hence, convection can occur via either oscillatory or steady motions. It is proved analytically that the onset of steady convection is not affected by the Vadasz term, while oscillatory convection is favoured by it. Moreover, conditions to rule out the occurrence of oscillatory convection are determined numerically. The influence of rotation, interaction coefficient and mechanical and thermal anisotropies on the onset of instability is investigated, both analytically and numerically.

description: A \emph{hull} of $A \subset [0,1]$ is a set $H$ containing $A$ such that $λ^*(H)=λ^*(A)$. We investigate all four versions of the following problem. Does there exist a monotone (wrt. inclusion) map that assigns a Borel/$G_δ$ hull to every negligible/measurable subset of $[0,1]$? Three versions turn out to be independent of ZFC (the usual Zermelo-Fraenkel axioms with the Axiom of Choice), while in the fourth case we only prove that the nonexistence of a monotone $G_δ$ hull operation for all measurable sets is consistent. It remains open whether existence here is also consistent. We also answer a question of Z. Gyenes and D. Pálvölgyi which asks if monotone hulls can be defined for every chain (wrt. inclusion) of measurable sets. We also comment on the problem of hulls of all subsets of $[0,1]$.

description: The recent huge increase in processing power of mobile devices allows them to be used for applications previously limited to the class of personal computers. Due to the increased portability and the extended means of interaction, mobile devices open up new fields of applications, which are not fully explored yet.

This thesis examines the feasibility of implementing dynamic binaural synthesis on the Android platform - which at the moment is the most widespread platform for mobile devices. The implementations of a low-cost head-tracking system and an Android application are derived and explained.

On the basis of the implementations, platform-specific obstacles and particularities are investigated and evaluated. It is shown that dynamic binaural synthesis on Android is possible with good results, but that there are several machanisms that prevent the software to make full use of the present hardware and thus degrade performance to a level below hardware capabilities.

Die enorm gestiegene Rechenleistung mobiler Geräte ermöglicht es mehr und mehr, diese auch für anspruchsvolle Anwendungen einzusetzen, welche bis vor kurzem noch der Klasse der Personal Computer vorbehalten waren. In Verbindung mit ihrer erhöhten Portabilität und ihren erweiterten Interaktions- möglichkeiten ergeben sich neue und bisher nicht vollkommen erschlossene Anwendungsgebiete.

Die vorliegende Arbeit untersucht die Umsetzbarkeit der dynamischen Binauralsynthese auf der Android-Plattform - der zu diesem Zeitpunkt verbreitetsten Plattform für mobile Geräte. Dazu werden die Implementationen eines mobilen Low-Cost Head-Tracking-Systems und einer Android-Anwendung hergeleitet und vorgestellt.

Anhand der Implementationen werden plattformspezifische Hürden und Besonderheiten erforscht und ausgewertet. Es wird gezeigt, dass die dynamische Binauralsynthese auf Android mit guten Ergebnissen möglich ist, es jedoch bestimmte Mechanismen gibt, welche das Erreichen von sehr guten und mit der Hardware prinzipiell erreichbaren Ergebnissen verhindern.

description: A set of 220 inhibitors belonging to different structure classes and having HIV-1 integrase activity were collected along with their experimental pIC50 values. Geometries of all the inhibitors were fully optimized using B3LYP/6-31 + G(d) level of theory. These ligands were docked against 4 different HIV-1 integrase receptors (PDB IDs: 4LH5, 5KRS, 3ZSQ and 3ZSV). 30 docked poses were generated for all 220 inhibitors and ligand interaction of the first docked pose and the docked pose with the highest score were analysed. Residue GLU170 of 4LH5 receptor shows the highest number of interactions followed by ALA169, GLN168, HIS171 and ASP167 residues. Hydrogen bonding and stacking are mainly responsible for the interactions of these inhibitors with the receptor. We performed Molecular Dynamics (MD) simulation to observe the root-mean-square deviation (RMSD), for measure the average change of displacement between the atoms for a particular frame with respect to a reference and The Root Mean Square Fluctuation (RMSF) for characterization of local changes along the protein chain of the docked complexes. Analogue based models were generated to predict the pIC50 values for integrase inhibitors using various types of descriptors such as constitutional, geometrical, topological, quantum chemical and docking based descriptors. The best models were selected on the basis of statistical parameters and were validated by training and test set division. A few new inhibitors were designed on the basis of structure activity relationship and their pIC50 values were predicted using the generated models. All the designed new inhibitors a very high potential and may be used as potent inhibitors of HIV integrase. These models may be useful for further design and development of new and potent HIV integrase inhibitors. Communicated by Ramaswamy H. Sarma

description: Respiratory syncytial virus (RSV) is an infectious viral pathogen that causing serious respiratory infection in adults and neonates. The only approved therapies for RSV are the monoclonal antibodies palivizumab and its derivative motavizumab. Both treatments are expensive and require a hospital setting for administration. A vaccine represents a safe, effective and cheaper alternative for preventing RSV infection. In silico prediction methods have proven to be valuable in speeding up the process of vaccine design. In this study, reverse vaccinology methods were used to predict the cytotoxic T lymphocytes (CTL) epitopes from the entire proteome of RSV strain A. From amongst 3402 predicted binders to 12 high frequency alleles from the Immune Epitope Database (IEDB), 567 had positive processing scores while 327 epitopes were predicted to be immunogenic. A thorough examination of the 327 epitopes for possible antigenicity, allergenicity and toxicity resulted in 95 epitopes with desirable properties. A BLASTp analysis revealed 94 unique and non-homologous epitopes that were subjected to molecular docking across the 12 high frequency alleles. The final dataset of 70 epitopes contained 13 experimentally proven and 57 unique epitopes from a total of 11 RSV proteins. From our findings on selected T-cell-specific RSV antigen epitopes, notably the four epitopes confirmed to exhibit stable binding by molecular dynamics. The prediction pipeline used in this study represents an effective way to screen the immunogenic epitopes from other pathogens. Communicated by Ramaswamy H. Sarma

description: Women in the tech sector in Ecuador have made significant progress to create a more inclusive sector in recent years, contributing with collective efforts to the country's growing digital landscape: They created initiatives promoting gender diversity and inclusion and have provided opportunities for more women to be part of the industry. The aim of the multi-stakeholder dialogue was to achieve a shared understanding of the perspectives, opportunities, and challenges that marginalised communities encounter in this field. Furthermore, strategies and measures were developed to address these challenges and promote equality and equity in Ecuador's technology sector.

description: We compute the Next-to-Next-to-Leading Order (NNLO) QCD corrections to the partonic reaction that dominates top-pair production at the Tevatron. This is the first ever NNLO calculation of an observable with more than two colored partons, and/or massive fermions, at hadron colliders. Augmenting our fixed order calculation with soft-gluon resummation through Next-to-Next-to-Leading Logarithmic (NNLL) accuracy, we observe that the predicted total inclusive cross-section exhibits a very small perturbative uncertainty, estimated at +-2.7%. We expect that once all sub-dominant partonic reactions are accounted for, and work in this direction is ongoing, the perturbative theoretical uncertainty for this observable could drop below +-2%. Our calculation demonstrates the power of our computational approach and proves it can be successfully applied to all processes at hadron colliders for which high-precision analyses are needed.

description: Spintronic THz emitters (STE) are efficient THz sources constructed using thin heavy-metal (HM) and ferromagnetic-metal (FM) layers. To improve the performance of the STE, different structuring methods (trilayers, stacked bilayers) have been experimentally applied. A theoretical description of the overall THz emission process is necessary to optimize the efficiency of STE. In particular, geometry, composition, pump laser frequency, and spin diffusion will be significant in understanding the pathways for further research developments. This work will apply a generalized model based on a modified Transfer Matrix Method (TMM). We will consider the spin generation and diffusion in the FM and HM layers and explain the spintronic THz emission process. This model is suitable for calculating emitted THz signal as a function of FM and HM thicknesses for different geometrical configurations. We will investigate a bilayer geometry as a test case, but the extension to a multi-layer configuration is straightforward. We will show how the different configurations of the sample will influence the THz emission amplitude.

description: This edition of the Digest is the sixth report released to date; Addendum document contains updates to the 2007-2008 Canadian Gambling Digest (Canadian Partnership for Responsible Gambling, 2009).
description: The Digest is arranged by subject matter, starting with general industry data (venues, games, charitable gaming licences), followed by revenues, revenue distributions, gambling participation, problem gambling prevalence, and problem gambling assistance (helpline calls, clients, counsellors, on-site support centres). Data in each section is presented in tables and charts. Accompanying text describes the data and highlights some of its more salient features. While considerable effort was made to ensure that the information in a given table or chart is comparable across provinces, this was not always possible due to differences in record keeping and other factors. Unless stated otherwise, all data pertain to fiscal 2007-08 (April 1, 2007 to March 31, 2008).
A new method for diagnosing and distinguishing magma mixing and overpressure events using chemical variations in plagioclase
Creators: name: Wilson, Heather Anne
Publisher: name: University of British Columbia
Year: 2010

description: Striking textural and petrologic evidence for mixing of basalt into silicic melts occurs in volcanic arc settings worldwide. These textures (e.g. mingled/banded pumices, inclusions), along with chemical signatures of mixing (e.g. zoning in solid solution minerals) found in many eruption products, support a popular hypothesis that magma mixing can trigger explosive eruptions through a variety of possible mechanisms. However, rigorous observational constraints on the nature of the underlying thermal and mechanical processes remain elusive. A method is developed based on Nomarski differential interferometry to image and quantitatively characterise quasi-periodic zoning in plagioclase at very high spatial resolution. Applied to individual crystals, variations in zoning with crystallographic direction confirm experimental measurements of anisotropic diffusivities for Ca²⁺Al³⁺ and Na⁺Si⁴⁺. When applied to the AD 1315 Kaharoa eruption of Tarawera Volcano, Taupo Volcanic Zone, New Zealand, periodic zoning at scale lengths of 3.1–12.4 μm is consistent with quasi-periodic convective motions within the magma chamber acting on timescales of 39 days to 1.8 years prior to eruption. The structure of the zoning is inconsistent with a single large basalt injection causing eruption. Rather, this eruptive episode may have been preceded by several small volume basaltic inputs, consistent with observations from mafic-silicic layered intrusions.

description: A number of policies and initiatives made by the government of Tanzania is an effort to improve the livelihood of its citizens by making Tanzania a middle income country by 2025. The higher learning institutions have subsequently responded by re-dressing their vision and objectives to support the government move through training and research. One of the attributes of the University of Dar es Salaam vision 2061 is to focus more on research and postgraduate training in order to provide high caliber human resource for other higher learning institutions and the industry to address societal challenges required to achieve the goal of becoming a middle income country. One of the principle challenges to realize this vision of Tanzania is having reliable and affordable electrical power supply accessible to all for higher level of industrial investment and services. There are plans to (a) increase generation capacity to surpass demand (10 GW by 2025), and (b) to extend access to 60-70% in rural areas. However, the use traditional means to manage power network (i.e. monitoring and control) and its resources (only few intelligent meters and the SCADA system for the high voltage transmission network) makes delivery reliability poor. The expansion to the rural areas will pose an even greater challenge. Hence, the use of smart power grid is unavoidable. The iGRID research training programme intends to generate the necessary technical and scientific skills to ensure sustainable implementation of smart grid. iGRID plans to introduce taught PhD programmes focusing on society, innovation and entrepreneurship in iGRID aspects. The collaboration with the KTH ICT School will help to build capacity at the University of Dar es Salaam as detailed in the proposal. The iGRID project proposes to support 10 PhD students (8 taught PhD at UDSM and 2 sandwich), 4 staff for post doc training on PhD supervision and teaching PhD, 8 M.Sc. (taught M.Sc. at UDSM), remote training through video conferencing and emphasis on technology transfer from university to the society. The focus of the overall program is to integrate the knowledge triangle: education-research-innovation by the methodology and structures used in the proposal and interaction and integration to open innovation environments. Clearly sustainability after the project period can be achieved and institutional long term co-operation is enhanced via cotutelle agreement based double degree doctoral program.
