description: We investigate the binding energy per nucleon and hadron properties in infinite and homogeneous nuclear matter within the framework of the in-medium modified Skyrme model. We first consider the medium modifications of the single hadron properties by introducing the optical potential for pion fields into the original Lagrangian of the Skyrme model. The parameters of the optical potential are well fitted to the low-energy phenomenology of pion-nucleus scattering. Furthermore, the Skyrme term is also modified in such a way that the model reproduces bulk properties of nuclear matter, in particular, the binding energy per nucleon. The present approach is self-consistent: the single hadron properties in a nuclear medium, their effective in-medium interactions, and the bulk matter properties are treated on the same footing.

On the theory of polarization radiation generated in the media with sharp boundaries

description: Polarization radiation arising when a charged particle moves uniformly in vacuum nearby the media possessing a finite permittivity $ε(ω) = ε^{\prime} + i ε^{\prime \prime}$ and sharp boundaries is considered. The method is developed in which polarization radiation is represented as a field of the current density induced in matter by the field of the moving charge. Solution is found for a problem of radiation arising when the particle moves along the axis of the cylindrical channel inside a thin screen of a finite radius and a finite permittivity. Depending on parameters of the problem, the solution obtained describes different types of polarization radiation: Cherenkov, transition, and diffraction radiations. In particular, when the channel radius approaches zero and external radius of the screen tends to infinity the expression found for radiated energy coincides with Pafomov solution for transition radiation in a slab. In another special case of ideal conductivity, the result obtained coincides with the one for diffraction radiation generated by the particle in the round hole in the thin screen. Solution is found for a problem of radiation generated when the charge moves nearby a rectangular screen possessing a finite permittivity. The expression derived describes diffraction and Cherenkov mechanisms of radiation and takes into account the multiple reflections of radiation inside the screen. Solution is also found for a problem of radiation generated when the particle moves nearby a thin grating consisting of a finite number of rectangular strips possessing a finite permittivity and separated with vacuum gaps (Smith-Purcell radiation). In the special case of an ideally conducting grating, the formula derived for radiated energy coincides with the one of the well-known surface current model.

description: We present an updated extraction of the proton electromagnetic form factor ratio, mu_p G_E/G_M, at low Q^2. The form factors are sensitive to the spatial distribution of the proton, and precise measurements can be used to constrain models of the proton. An improved selection of the elastic events and reduced background contributions yielded a small systematic reduction in the ratio mu_p G_E/G_M compared to the original analysis.

On the vacuum fluctuations, Pioneer Anomaly and Modified Newtonian Dynamics

description: We argue that the so-called "Pioneer Anomaly" is related to the quantum vacuum fluctuations. Our approach is based on the hypothesis of the gravitational repulsion between matter and antimatter, what allows considering, the virtual particle-antiparticle pairs in the physical vacuum, as gravitational dipoles. Our simplified calculations indicate that the anomalous deceleration of the Pioneer spacecrafts could be a consequence of the vacuum polarization in the gravitational field of the Sun. At the large distances, the vacuum polarization by baryonic matter could mimic dark matter what opens possibility that dark matter do not exist, as advocated by the Modified Newtonian Dynamics (MOND).

description: We investigate the stability of growing vesicles using the formalism of nonequilibrium thermodynamics. The vesicles are growing due to the accretion of lipids to the bilayer which forms the vesicle membrane. The thermodynamic description is based on the hydrodynamics of a water{/}lipid mixture together with a model of the vesicle as a discontinuous system in the sense of linear nonequilibrium thermodynamics. This formulation allows the forces and fluxes relevant to the dynamic stability of the vesicle to be identified. The method is used to analyze the stability of a spherical vesicle against arbitrary axisymmetric perturbations. It is found that there are generically two critical radii at which changes of stability occur. In the case where the perturbation takes the form of a single zonal harmonic, only one of these radii is physical and is given by the ratio $2 L_p / L_γ$, where $L_p$ is the hydraulic conductivity and $L_γ$ is the Onsager coefficient related to changes in membrane area due to lipid accretion. The stability of such perturbations is related to the value of $l$ corresponding to the particular zonal harmonic: those with lower $l$ are more unstable than those with higher $l$. Possible extensions of the current work and the need for experimental input are discussed.

description: The EDELWEISS-II collaboration has completed a direct search for WIMP dark matter with an array of ten 400-g cryogenic germanium detectors in operation at the Laboratoire Souterrain de Modane. The combined use of thermal phonon sensors and charge collection electrodes with an interleaved geometry enables the efficient rejection of gamma-induced radioactivity as well as near-surface interactions. A total effective exposure of 384 kg.d has been achieved, mostly coming from fourteen months of continuous operation. Five nuclear recoil candidates are observed above 20 keV, while the estimated background is 3.0 events. The result is interpreted in terms of limits on the cross-section of spin-independent interactions of WIMPs and nucleons. A cross-section of 4.4x10^-8 pb is excluded at 90%CL for a WIMP mass of 85 GeV. New constraints are also set on models where the WIMP-nucleon scattering is inelastic.

description: We study the observational constraints on the Phantom Crossing DGP model. We demonstrate that the crossing of the phantom divide does not occur within the framework of the original Dvali-Gabadadze-Porrati (DGP) model or the DGP model developed by Dvali and Turner. By extending their model in the framework of an extra dimension scenario, we study a model that realizes crossing of the phantom divide. We investigate the cosmological constraints obtained from the recent observational data of Type Ia Supernovae, Cosmic Microwave Background anisotropies, and Baryon Acoustic Oscillations. The best fit values of the parameters with 1$σ$ (68%) errors for the Phantom Crossing DGP model are $Ω_{m,0}=0.27^{+0.02}_{-0.02}$, $β=0.54^{+0.24}_{-0.30}$. We find that the Phantom Crossing DGP model is more compatible with the observations than the original DGP model or the DGP model developed by Dvali and Turner. Our model can realize late-time acceleration of the universe, similar to that of $Λ$CDM model, without dark energy due to the effect of DGP gravity. In our model, crossing of the phantom divide occurs at a redshift of $z \sim 0.2$.

description: We study nonequilibrium work relations for a space-dependent field with stochastic dynamics (Model A). Jarzynski's equality is obtained through symmetries of the dynamical action in the path integral representation. We derive a set of exact identities that generalize the fluctuation-dissipation relations to non-stationary and far-from-equilibrium situations. These identities are prone to experimental verification. Furthermore, we show that a well-studied invariance of the Langevin equation under supersymmetry, which is known to be broken when the external potential is time-dependent, can be partially restored by adding to the action a term which is precisely Jarzynski's work. The work identities can then be retrieved as consequences of the associated Ward-Takahashi identities.

description: We present an efficient method for subrecoil cooling of neutral atoms by applying Raman cooling in 2D to a four-level tripod-system. The atoms can be cooled simultaneously in two directions using only three laser beams. We describe the cooling process with a simple model showing that the momentum distribution can be rapidly narrowed to velocity spread down to $0.1v_\text{rec}$, corresponding to effective temperature equal to $0.01T_\text{rec}$. This method opens new possibilities for cooling of neutral atoms.

description: The experimental investigation of spontaneously created vortices is of utmost importance for the understanding of quantum phase transitions towards a superfluid phase, especially for two dimensional systems that are expected to be governed by the Berezinski-Kosterlitz-Thouless physics. By means of time resolved near-field interferometry we track the path of such vortices, created at random locations in an exciton-polariton condensate under pulsed non-resonant excitation, to their final pinning positions imposed by the stationary disorder. We formulate a theoretical model that successfully reproduces the experimental observations.

description: We discuss various aspects of excited state TBA equations describing the energy spectrum of the AdS_5 \times S^5 strings and, via the AdS/CFT correspondence, the spectrum of scaling dimensions of N = 4 SYM local operators. We observe that auxiliary roots which are used to partially enumerate solutions of the Bethe-Yang equations do not play any role in engineering excited state TBA equations via the contour deformation trick. We further argue that the TBA equations are in fact written not for a particular string state but for the whole superconformal multiplet, and, therefore, the psu(2,2|4) invariance is built in into the TBA construction.

Surface Conditioning Effects on Horizontal Gene Transfer

Publisher: name: Zenodo

description: Biofilms have been suggested as hotspots for horizontal gene transfer (HGT), in which antibiotic resistance genes can be disseminated to potential foodborne pathogens via direct cell-to-cell contact (conjugation). They facilitate the exchange of nucleic acids because of the proximity and long retention time of cells within the matrix. Bacterial adhesion and subsequent biofilm formation begin with surface conditioning by components of the culture medium or cell-derived compounds originating from cell lysis. The general question we were trying to answer was whether surface conditioning with cellular extracts affects HGT and potentially the consequent spread of antimicrobial resistance in food environments.
Total cell extract (TCE), cytoplasm with cellular debris (CCDE), and periplasmic extract (PE) were the three types of cellular extracts tested as surface conditioning agents. Escherichia coli and Pseudomonas putida carrying the conjugative IncP-1 plasmid pKJK5 were used as donor strains in dual-species biofilms and three biofilm platforms – 96-well polystyrene microplate (MP), 24-well MP with stainless steel (SST) coupons and drip flow reactor (DFR) – were tested, which differed in the substratum (polystyrene or SST) and hydrodynamic conditions (static or flow). The bacterial population and plasmid transfer frequencies were assessed using flow cytometry.
For the two static platforms, the amount of biofilm formed on SST coupons placed in 24-well MPs was not affected by surface conditioning, in contrast to what was observed in 96-well MPs. Preconditioning the polystyrene wells with cell extracts did not affect pKJK5 transfer compared with unconditioned polystyrene, regardless of the donor strain. Nonetheless, cell extracts reduced about 2-fold the transconjugant/donor ratio within E. coli biofilms formed on SST. Under dynamic conditions, the impact of surface conditioning was more evident, namely in single- and dual-species biofilms of E. coli, in which TCE and CCDE reduced the number of adhered bacteria by up to 82%. It was also observed that the transconjugant/donor ratio was higher under flow than under static conditions. However, no transfer of the pKJK5 plasmid was detected in the drip flow system when P. putida was used as the donor strain.
This study highlights the importance of considering surface conditioning and its influence on biofilm bacterial dynamics, and consequently, on plasmid transfer.

description: By means of lattice-based Monte Carlo simulations, we address properties of two-component lipid membranes on the experimentally relevant spatial scales of order of a micrometer and time intervals of order of a second, using DMPC/DSPC lipid mixtures as a model system. Our large-scale simulations allowed us to obtain important results previously not reported in simulation studies of lipid membranes. We find that, within a certain range of lipid compositions, the phase transition from the fluid phase to the fluid-gel phase coexistence proceeds via near-critical fluctuations, while for other lipid compositions this phase transition has a quasi-abrupt character. In the presence of near-critical fluctuations, transient subdiffusion of lipid molecules is observed. These features of the system are stable with respect to perturbations in lipid interaction parameters used in our simulations. The line tension characterizing lipid domains in the fluid-gel coexistence region is found to be in the pN range. When approaching the critical point, the line tension, the inverse correlation length of fluid-gel spatial fluctuations, and the corresponding inverse order parameter susceptibility of the membrane vanish. All these results are in agreement with recent experimental findings for model lipid membranes. Our analysis of the domain coarsening dynamics after an abrupt quench of the membrane to the fluid-gel coexistence region reveals that lateral diffusion of lipids plays an important role in the fluid-gel phase separation process.

Innovation in hybrid mass timber high-rise construction : a case study of UBC’s Brock Commons project
Creators: name: Fallahi, Azadeh
Publisher: name: University of British Columbia
Year: 2017

description: With the advocacy for sustainable construction on the rise, use of timber as the main building material is being championed in large-scale construction projects. While the advancement of engineered timber products is addressing some issues that previously limited the use of wood in high-rise construction, there are still challenges such as fire and weather safety, code compliance and negative public perceptions. One main gap in the available resources is the lack of a comprehensive and detailed case study of a high-rise project with wood as the main construction material to capture constraints and innovations necessary in creating success, which has formed the direction of this research. This thesis is focused on documenting a case study of the Brock Commons project, an 18 storey, hybrid timber-concrete residential high-rise located at the University of British Columbia, Vancouver campus, which is the tallest hybrid timber building in the world. The overall research objective was to identify and document the delivery of this innovative project, with a specific emphasis on the innovations necessary to make timber high-rise construction successful and the use of VDC tools in the design and pre-construction process. The case study documents the project context, the design process, the business and industry drivers, and the motivation for construction. Moreover, it investigates the motivations for all stakeholders, identifies the challenges and constraints, and captures the innovative solutions that were utilized to ensure project success. The case study also documents the innovative use of VDC to support prefabrication and overall project coordination. Specifically, it investigates the role of the VDC integrators in the project, the paths of communications with the different project team members, and the inputs and outputs of each phase of design and construction. This research identified lessons learned that can be applied to other construction projects where timber is the main structural component and a heavy use of VDC and pre-fabrication is required. Use of timber and innovative methods in construction have been consistently rising in the past decade, and this research aims to provide a starting point for future efforts in mass timber high-rise construction.

description: The anti--de Sitter/conformal field theory (AdS/CFT) correspondence is a powerful tool that promises to provide new insights toward a full understanding of field theories under extreme conditions, including but not limited to quark-gluon plasma, Fermi liquid and superconductor. In many such applications, one typically models the field theory with asymptotically AdS black holes. These black holes are subjected to stringy effects that might render them unstable. Hořava-Lifshitz gravity, in which space and time undergo different transformations, has attracted attentions due to its power-counting renormalizability. In terms of AdS/CFT correspondence, Hořava-Lifshitz black holes might be useful to model holographic superconductors with Lifshitz scaling symmetry. It is thus interesting to study the stringy stability of Hořava-Lifshitz black holes in the context of AdS/CFT. We find that uncharged topological black holes in $λ=1$ Hořava-Lifshitz theory are nonperturbatively stable, unlike their counterparts in Einstein gravity, with the possible exceptions of negatively curved black holes with detailed balance parameter $ε$ close to unity. Sufficiently charged flat black holes for $ε$ close to unity, and sufficiently charged positively curved black holes with $ε$ close to zero, are also unstable. The implication to the Hořava-Lifshitz holographic superconductor is discussed.

description: The tensor and spin-orbit forces contribute essentially to the formation of the spin mean field, and give rise to the same dynamical effect, namely spin polarization. In this paper, based on time-dependent density functional calculations, we show that the tensor force, which usually acts like a small correction to the spin-orbit force, becomes more important in heavy-ion reactions and the effect increases with the mass of the system.

The introduction of invasive species is a significant driving force of global change.

Weed scientists, resource managers, conservation and restoration biologists have

focused their attention on the control of invasive species trying to understand,

mitigate and prevent impacts of biological invasions. Biological control, the control of

invading organisms by means of their natural enemy, is one way to prevent impacts of

biological invasions. Mathematical models are a useful tool for the design of biological

control strategies. These models allow for the analysis of population growth and

spread, and for determination of aspects of the life cycle of the organisms which can

be manipulated to control populations. In this dissertation I use matrix models to

study the life history of invading organisms. First, a new method for the calculation of

an analytical net reproductive rate formula is derived. I show with examples how this

formula can be applied to study the control of invading organisms, particularly weeds.

I extend these results, to calculate a mean and variance of the generation time. Later

in the thesis, I use coupled map lattice models, a time and space discrete formalism,

to calculate rate of spread for scalar and matrix population models. I derive formulae

for the wave speed for constant and stochastic environments for coupled map lattices.

I then apply these to scentless chamomile, an invasive weed distributed all across

North America. The methods for calculation of net reproductive rate and generation

time, and formulae for rate of spread in coupled map lattices, are new to biological

invasions and biological control.

description: A homogeneous polarized dipolar Bose-Einstein condensate is considered in the presence of weak quenched disorder within mean-field theory at zero temperature. By first solving perturbatively the underlying Gross-Pitaevskii equation and then performing disorder ensemble averages for physical observables, it is shown that the anisotropy of the two-particle interaction is passed on to both the superfluid density and the sound velocity.

description: Nowadays, due to globally increasing building densities in cities, demolition works are an inherent part of construction. And they are focal activities related to life-cycle-oriented management of construction materials, which aims at drastically reduce the deployment and consumption of primary non-renewable construction materials. To give an overview on related worldwide existing activities, the state of the art of demolition and of reuse and recycling of construction materials is summarized in a report of selected countries based on reports of these countries. Within this report, first typical structures of the demolition and recycling industry in different countries, typical phases of demolition and recycling processes and involved stakeholders with their characteristic competencies are described. Secondly, leading companies, associations and research institutions in selected countries are outlined. Leading processes are identified by distinguishing between design processes for deconstruction, deconstruction processes on-site and innovative on-site and off-site recycling processes. Thirdly, challenges related to demolition and reuse and recycling of construction materials are identified and analysed in terms of technical, economic, ecologic, organizational and educational and political/legal challenges. Finally, single, country specific, already existing approaches to meet these challenges are identified.

description: In this paper we study the spin transport in frustrated antiferromagnetic FCC films by Monte Carlo simulation. In the case of Ising spin model, we show that the spin resistivity versus temperature exhibits a discontinuity at the phase transition temperature: an upward jump or a downward fall, depending on how many parallel and antiparallel localized spins interacting with a given itinerant spin. The surface effects as well as the difference of two degenerate states on the resistivity are analyzed. Comparison with non frustrated antiferromagnets is shown to highlight the frustration effect. We also show and discuss the results of the Heisenberg spin model on the same lattice.

description: A cold relic axion condensate resulting from vacuum misalignment in the early universe oscillates with a frequency m, where m is the axion mass. We determine the properties of photons propagating in a simplified version of such a background where the sinusoidal variation is replaced by a square wave profile. We prove that previous results that indicated that charged particles moving fast in such a background radiate, originally derived assuming that all momenta involved were much larger than m, hold for long wavelengths too. We also analyze in detail how the introduction of a magnetic field changes the properties of photon propagation in such a medium. We briefly comment on possible astrophysical implications of these results.

description: We perform a systematic study of incoherent transport in the high temperature crossover region of the half-filled one-band Hubbard model. We demonstrate that the family of resistivity curves displays characteristic quantum critical scaling of the form $ρ(δU,T)=ρ_{c}(T)f(T/T_{o}(δU))$, with $T_{o}(δU)\simδU^{zν}$, and $ρ_{c}(T)\sim T$. The corresponding $β$-function displays a "strong coupling" form $β\sim\ln(ρ_{c}/ρ)$, reflecting the peculiar mirror symmetry of the scaling curves. This behavior, which is surprisingly similar to some experimental findings, indicates that Mott quantum criticality may be acting as the fundamental mechanism behind the unusual transport phenomena in many systems near the metal-insulator transition.

description: In this work we present 3-algebraic constructions and representations for three-dimensional N = 5 supersymmetric Chern-Simons theories, and show how they relate to theories with additional supersymmetries. The N = 5 structure constants give theories with Sp(2N) \times SO(M) gauge symmetry, as well as more exotic symmetries known from gauged supergravity. We find explicit lifts from N = 6 to 8, and N = 5 to 6 and 8, for appropriate gauge groups.

Berlin’s Manifold Strategies Towards Commercial and Industrial Spaces: The Different Cases of Zukunftsorte

description: Despite being the third largest industrial agglomeration in the world before World War II, Berlin was faced with an economic void after the partition and reunification of the city with many abandoned and alienated commercial and industrial spaces in a compact urban fabric. What has happened with this commercial and industrial heritage over the last 30 years? The main rationale behind this article is to show how Berlin planned and developed some of these spaces through the Zukunftsorte strategy by preserving its historical sites and modernizing its commercial and industrial base. As part of this undertaking, the article combines insights from urban planning and regional innovation studies. Methodologically, a two-step approach is applied: First, the article conducts an analysis of fundamental planning frameworks and technology/innovation policy trajectories with regard to commercial and industrial spaces; second, a multiple-case study analysis of selected Zukunftsorte (Adlershof, Marzahn, Schöneberg, Siemensstadt) is carried out to test whether and to what extent those spaces are supported by planning frameworks and exhibit components of what we coined territorial ecosystem models. The data compiled stems from 15 years of work engaging in various planning and policy steering committees, individual or joint research projects, personal interviews with relevant stakeholders, and regular field observations. The findings suggest that Berlin’s strategies towards commercial and industrial spaces need to integrate highly contextual approaches since size, progress, operation, means, and timelines of Zukunftsorte vary substantially. Whereas Adlershof is a well-functioning network of business, academia, planners, and policymakers with preliminary attempts to embed those stakeholders in residential neighborhoods and the European Energy Forum in Schöneberg—which can be described as a miniature living lab of Adlershof—the other investigated Zukunftsorte do not yet deserve to carry this name.

An Iterative Joint Linear-Programming Decoding of LDPC Codes and Finite-State Channels
Creators: name: Kim, Byung-Hak
name: Pfister, Henry D.
Publisher: name: arXiv
Year: 2010
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: In this paper, we introduce an efficient iterative solver for the joint linear-programming (LP) decoding of low-density parity-check (LDPC) codes and finite-state channels (FSCs). In particular, we extend the approach of iterative approximate LP decoding, proposed by Vontobel and Koetter and explored by Burshtein, to this problem. By taking advantage of the dual-domain structure of the joint decoding LP, we obtain a convergent iterative algorithm for joint LP decoding whose structure is similar to BCJR-based turbo equalization (TE). The result is a joint iterative decoder whose complexity is similar to TE but whose performance is similar to joint LP decoding. The main advantage of this decoder is that it appears to provide the predictability of joint LP decoding and superior performance with the computational complexity of TE.

Decoherent Histories Quantum Mechanics with One 'Real' Fine-Grained History

description: Decoherent histories quantum theory is reformulated with the assumption that there is one "real" fine-grained history, specified in a preferred complete set of sum-over-histories variables. This real history is described by embedding it in an ensemble of comparable imagined fine-grained histories, not unlike the familiar ensemble of statistical mechanics. These histories are assigned extended probabilities, which can sometimes be negative or greater than one. As we will show, this construction implies that the real history is not completely accessible to experimental or other observational discovery. However, sufficiently and appropriately coarse-grained sets of alternative histories have standard probabilities providing information about the real fine-grained history that can be compared with observation. We recover the probabilities of decoherent histories quantum mechanics for sets of histories that are recorded and therefore decohere. Quantum mechanics can be viewed as a classical stochastic theory of histories with extended probabilities and a well-defined notion of reality common to all decoherent sets of alternative coarse-grained histories.
