description: The dynamics of molecular motors which occasionally detach from a heterogeneous track like DNA or RNA is considered. Motivated by recent single molecule experiments, we study a simple model for a motor moving along a disordered track using chemical energy while an external force opposes its motion. The motors also have finite processivity, i.e., they can leave the track with a position dependent rate. We show that the response of the system to disorder in the hopping off rate depends on the value of the external force. For most values of the external force, strong disorder causes the motors which survive for long times on the track to be localized at preferred positions. However, near the stall force, localization occurs for any amount of disorder. Existence of localized states near the top of the band implies a stretched exponential contribution to the decay of the survival probability. To obtain these results, we study the complex eigenvalue spectrum of the time evolution operator. A similar spectral analysis also provides a very efficient method for studying the dynamics of motors with infinite processivity.

description: Understanding and controlling the hydrolysis and condensation of trialkoxy and tetraalkoxy silanes in acidic medium (Figure A) has not been fully realised. In this research study, both the understanding and control has been achieved using methods developed from the VitolaneTM process invented by TWI Ltd1 our industrial collaborators. The VitolaneTM process involves the synthesis of 3-methacryloxypropylsilsesquioxane resin from the hydrolytic condensation of 3-methacryloxy-propyltrimethoxysilane (MPTMS) in the presence of methanol, water and an acid catalyst (A-system). The reaction was repeated with two starting materials; 3-methacryloxy-propyltrimethoxysilane (MPTMS) and n-propyltrimethoxysilane (nPTMS) to form the AZ-system. It was found that with certain compositions, the reaction quickly reaches a pseudo equilibrium hence the hydrolysis rate constant could be determined. The instrumental analysis using Maldi-ToF-MS, HPLC, GPC, TGA, GCMS, DLS, DSC, FTIR and CHN analysis of both types of resins gave results that suggested the organic-inorganic hybrid silsesquioxanes obtained had the expected chemical composition and unique physical properties. This study was further extended to Stöber sphere silica nanoparticles aimed at extending our understanding from the above hydrolysis and condensation mechanistic study to the synthesis of Stöber silica nanoparticles 2 of various sizes (Figure B). The synthesis follows a similar pattern as the VitolaneTM process but using TEOS as starting material and ammonium hydroxide base instead of acid as in the original VitolaneTM process. Figure A Figure B The Stöber spheres study was carried out so we could add them to Vitolane in order to give rough (on the nanoscale) surfaces that would be superhydrophobic. The Stöber spheres were characterized using transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and dynamic light scattering (DLS) to investigate the particle size formation. The Stöber spheres obtained were of varied sizes depending upon the way they were prepared (Figure B).

description: Two-dimensional transition metal dichalcogenides (TMDs) usually exist in two or more structural phases with different physical properties, and can be repeatedly switched between these phases via different stimuli, making them potentially useful for memory devices. An understanding of the physics of interfaces between the TMDs and conventional semiconductors, or other 2D-crystals forming heterogenous or homogeneous assemblies is central to their successful application in technologies. However, to date, most theoretical works have explored phase-change properties of isolated TMD monolayers in vacuum. Using \textit{ab-initio} calculations, we show how interfacial effects modify the thermodynamics and kinetics of the phase transition by studying hydrogen-induced transitions in monolayers and bilayers of MoTe$_{2}$. The phase-change properties of MoTe$_{2}$ show substantial thickness-dependence, with the timescale for a transition in the hydrogenated bilayer being about $10^7$-times longer than that in a monolayer at room temperature. Our study highlights the importance of taking effects of immediate environment into account when predicting properties of 2D crystals.

description: In this study an attempt is made to investigate the cooling impact of a nocturnal radiator system for a building in the urban environment of Athens, Greece. The dynamic thermal performance of the system is calculated using an accurate mathematical model, based on the heat transferred from the air circulating inside the radiator to the ambient air. The system’s main function is to cool the ambient air below its designed initial temperature. The cooler air is directed and eventually mixed with the indoor air of the building to provide primarily instantaneous thermal comfort during the night and secondly to cool the interior of the building by convection, thus creating a cold storage for the following day. The energy consumption and the cooling-heating loads are calculated for a typical single story building during the summer period with the aid of the EnergyPlus simulation programme. The validation process was extended for three radiator’s air flow values in order to investigate the impact of different air flows on the system’s efficiency. Moreover, the more effective air flow value of the radiator was used to provide space cooling or pre-cooling for the building. Indoor air temperature values of the thermal zone connected with the radiator were compared with those of the same zone without any cooling system and the results demonstrated a remarkable effectiveness of the system.

description: We present a new method for matching the two twin-processes gb->H+/-t and gg->H+/-tb in Monte Carlo event generators. The matching is done by defining a double-counting term, which is used to generate events that are subtracted from the sum of these two twin-processes. In this way we get a smooth transition between the collinear region of phase space, which is best described by gb->H+/-t, and the hard region, which requires the use of the gg->H+/-tb process. The resulting differential distributions show large differences compared to both the gb-> H+/-t and gg->H+/-tb processes illustrating the necessity to use matching when tagging the accompanying b-jet.

description: The green marketing strategies attempt to assign greater value to products highlighting their aspects related to preservation of the environment and sustainability. The present study sought to verify whether the application of the green marketing strategies in the marketing of organic products aggregates, in consumer perception, greater value to food products. The study was conducted in three stages with distinct methodological nature and character, in which it sought to identify the provision of consumers to pay more for organic products, understand the reasons why there is or is not available and discuss the strategies used in the marketing of these products. The results demonstrated that the green marketing strategies applied on the marketing of organic products really created greater value in the design of a good part of the consumers, and that a considerable portion of them, demonstrates willingness to pay an additional amount to consume such products. However, many of these consumers don’t have a real concept of what is an organic product, what are the benefits, and in these cases, more effective strategies for communicating value are required.

description: We compare the primordial scalar power spectra in the loop cosmological models using the effective dynamics of the hybrid approach to cosmological perturbations in which the background is loop quantized but the perturbations are Fock quantized. The three loop cosmological models under consideration are the standard LQC, the modified LQC-I (mLQC-I) and the modified LQC-II (mLQC-II) in the spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) universe with a Starobinsky potential. These models arise from different regularizations of the classical Hamiltonian constraint in the symmetry reduced spacetimes and aim to capture certain features of quantization in loop quantum gravity. When applying the techniques in the hybrid approach to mLQC-I/II, we find the effective Mukhanov-Sasaki equations take the same form as in LQC. The difference among the three models is encoded in the unique expressions of the effective masses in each model. We find that the relative difference in the amplitude of power spectrum between LQC and mLQC-II is approximately $50\%$ in the infrared and the oscillatory regimes, whereas this difference can be as large as $100\%$ between mLQC-I and LQC/mLQC-II. Interestingly, in the infrared and the oscillatory regimes of mLQC-I, we obtain a suppressed power spectrum from the hybrid approach which is far below the Planck scale. This result is in a striking contrast to the one obtained from dressed metric approach to perturbations where the corresponding amplitude in this regime is extremely large. Our analysis shows that while the phenomenological predictions are in agreement between two approaches for LQC and mLQC-II, for mLQC-I the differences between dressed and hybrid approaches can be quite significant. Our result provides the first robust evidence of difference in predictions between dressed and hybrid approaches due to respective underlying constructions.

description: The replacement of the existing endcap calorimeter in the Compact Muon Solenoid (CMS) detector for the high-luminosity LHC (HL-LHC), scheduled for 2027, will be a high granularity calorimeter. It will provide detailed position, energy, and timing information on electromagnetic and hadronic showers in the immense pileup of the HL-LHC. The High Granularity Calorimeter (HGCAL) will use 120-, 200-, and 300-$μ\textrm{m}$ thick silicon (Si) pad sensors as the main active material and will sustain 1-MeV neutron equivalent fluences up to about $10^{16}~\textrm{n}_\textrm{eq}\textrm{cm}^{-2}$. In order to address the performance degradation of the Si detectors caused by the intense radiation environment, irradiation campaigns of test diode samples from 8-inch and 6-inch wafers were performed in two reactors. Characterization of the electrical and charge collection properties after irradiation involved both bulk polarities for the three sensor thicknesses. Since the Si sensors will be operated at -30 $^\circ$C to reduce increasing bulk leakage current with fluence, the charge collection investigation of 30 irradiated samples was carried out with the infrared-TCT setup at -30 $^\circ$C. TCAD simulation results at the lower fluences are in close agreement with the experimental results and provide predictions of sensor performance for the lower fluence regions not covered by the experimental study. All investigated sensors display 60$\%$ or higher charge collection efficiency at their respective highest lifetime fluences when operated at 800 V, and display above 90$\%$ at the lowest fluence, at 600 V. The collected charge close to the fluence of $10^{16}~\textrm{n}_\textrm{eq}\textrm{cm}^{-2}$ exceeds 1 fC at voltages beyond 800 V.

Based on a two-fluid model, we calculate the compliance and discuss it for two cases. We first assume that the elastic and fluid component exhibit both stick boundary conditions at the particle surface. Then, the compliance fulfills a generalized Stokes law with a complex shear modulus whose validity is only limited by inertial effects, in contrast to translational motion. Secondly, we find that the validity of the Stokes regime is reduced when the elastic network is not coupled to the particle

Resistive Accretion Flows around a Kerr Black Hole

description: In this paper, we present the stationary axisymmetric configuration of a resistive magnetised thick accretion disc in the vicinity of external gravity and intrinsic dipolar magnetic field of a slowly rotating black hole. The plasma is described by the equations of fully general relativistic magnetohydrodynamics (MHD) along with the Ohm's law and in the absence of the effects of radiation fields. We try to solve these two-dimensional MHD equations analytically as much as possible. However, we sometimes inevitably refer to numerical methods as well. To fully understand the relativistic geometrically thick accretion disc structure, we consider all three components of the fluid velocity to be non-zero. This implies that the magnetofluid can flow in all three directions surrounding the central black hole. As we get radially closer to the hole, the fluid flows faster in all those directions. However, as we move towards the equator along the meridional direction, the radial inflow becomes stronger from both the speed and the mass accretion rate points of view. Nonetheless, the vertical (meridional) speed and the rotation of the plasma disc become slower in that direction. Due to the presence of pressure gradient forces, a sub-Keplerian angular momentum distribution throughout the thick disc is expected as well. To get a concise analytical form of the rate of accretion, we assume that the radial dependency of radial and meridional fluid velocities is the same. This simplifying assumption leads to radial independency of mass accretion rate. The motion of the accreting plasma produces an azimuthal current whose strength is specified based on the strength of the external dipolar magnetic field. This current generates a poloidal magnetic field in the disc which is continuous across the disc boundary surface due to the presence of the finite resistivity for the plasma.

description: Black holes found in binaries move at very high velocities relative to our own reference frame and can accelerate due to the emission of gravitational radiation. Here, we investigate the numerical stability and late-time behavior of linear scalar perturbations in accelerating black holes described by the $C-$metric. We identify a family of quasinormal modes associated with the photon surface and a brand new family of purely imaginary modes associated with the boost parameter of the accelerating black hole spacetime. When the accelerating black hole is charged, we find a third family of modes which dominates the ringdown waveform near extremality. Our frequency and time domain analysis indicate that such spacetimes are stable under scalar fluctuations, while the late-time behavior follows an exponential decay law, dominated by quasinormal modes. This result is in contrast with the common belief that such perturbations, for black holes without a cosmological constant, always have a power-law cutoff. In this sense, our results suggest that the asymptotic structure of black hole backgrounds does not always dictate how radiative fields behave at late times.

Effects of serotonin on the excitability and mechanical thresholds of masticatory muscle afferent fibre
Creators: name: Sung, David
Publisher: name: University of British Columbia
Year: 2010

description: Recent human clinical evidence suggests a relationship between intramuscular (IM) serotonin (5-HT) levels and chronic masticatory muscle pain associated with temporomandibular disorders (TMDs) and fibromyalgia (FM). Further, human experimental pain studies have demonstrated that injection of 5-HT into masticatory muscle causes modest, short-lived pain and a longer-lasting mechanical sensitization that appear to be mediated by activation of peripheral 5-HT3 receptors. However, it has not yet been clearly delineated what 5-HT₃ receptor types are expressed by sensory (afferent) fibres that innervate masticatory muscle. Also, it is not known what types of muscle afferent fibres 5-HT excites or sensitizes. In this study, immunohistochemistry techniques were used to determine the frequencies of expression of the 5-HT₁, 5-HT₂, and 5-HT₃ receptors by rat masticatory muscle ganglion cells. Electrophysiology experiments were carried out to determine the effects of repeated IM injection of 5-HT (0.1, 1, or 10 mM) on the excitability and mechanical thresholds of rat masticatory muscle afferent fibres. An electronic Von Frey Hair was used to measure afferent fibre mechanical thresholds before the initial and 10 min after the second IM injection. Our immunohistochemistry results suggest that 5-HT₁B[subscript] and especially 5-HT₁A[subscript] receptors, owing to their low frequencies of expression, may play minor roles in peripheral nociceptive transduction in uninflamed muscle tissue. In contrast, 5-HT₃ receptors, which are relatively highly expressed, likely play a more prominent role in peripheral nociception. Our electrophysiology results demonstrate that IM injection of 5-HT evokes rapid, relatively reproducible and concentration-dependent increases in afferent fibre excitability that are mediated, at least in part, by a peripheral receptor mechanism involving the 5-HT₃ receptor. However, IM injection of 5-HT did not significantly sensitize putative muscle afferent fibres to mechanical stimuli. We unexpectedly found that IM injection of 5-HT resulted in a marked decrease in blood pressure, a phenomenon that has yet to be explained. These findings indicate that 5-HT excites putative nociceptive afferent fibres that innervate masticatory muscle through activation of peripheral 5-HT₃ receptors, which suggests that the peripheral 5-HT₃ receptor may be an important target for future analgesic drugs.

description: Bevölkerungswachstum, gesellschaftliche Wandlungsprozesse und steigende Urbanisierung sind eine der wichtigsten Anforderungen an die Architektur und Stadtplanung der Zukunft. Die Herausforderung ist es, nicht nur neuen Wohnraum zu produzieren, sondern auch auf die ständig wechselnden Bedürfnisse der Bewohner einzugehen. Neue Organisationsformen der Arbeit, diskontinuierliche Lebensformen und die wandelnde Alltagskultur wirken sich auf den individuellen und kollektiven Raumbedarf aus. Welchen Einfluss haben diese Veränderungen und die Vielfalt der Lebensentwürfe auf den gebauten Raum und wie kann dieser den Wünschen der zukünftigen Generationen gerecht bleiben? Das brachliegende Areal in St. Marx, das zunächst als Standort für die ORF Zentrale angedacht war, wird zum Arbeits- und Wohnquartier für Familien, Alleinerziehende, Singles, Studenten und andere neue Lebensformen. Ein Campus, für die sich in Wien zurzeit Rasch entwickelnde Start-Up Community und das so gennante 'besondere Wohnen' wird als Antwort auf die Bedürfnisse der Gesellschaft angeboten und bildet ein urbanes Areal, welches sich in das entwickelnde 'Neu Marx' Stadtteil einfügen soll.
description: Population growth, social changes and increasing urbanization are one of the most important requirements for future architecture and urban planning. The challenge is to not only produce new living space, but also to respond to the constantly changing needs of the residents. New organizational forms of work, discontinuous lifestyles and the changing everyday culture have an impact on individual and collective space requirements. What influences do these changes and the diversity of life plans have on the built space and how can it meet the wishes of the future generations? The fallow area in St. Marx, which was initially planned as a site for the ORF headquarters, becomes a working and living quarter for families, single parents, singles, students and other new lifestyles. A campus for the fast developing start-up community in Vienna and the so called 'special living' is offered in response to the needs of a new society and forms a new urban area that will be integrated into the developing -Neu Marx- district.

description: Using nonlinear, fully relativistic, simulations we investigate the dynamics and gravitational-wave signature associated with instabilities in neutron star postmerger remnants. For simplified models of the remnant we establish the presence of an instability in stars with moderate $T/|W|$, the ratio between the kinetic and the gravitational potential energies. Detailed analysis of the density oscillation pattern reveals a \emph{local} instability in the inner region of the more realistic differential rotation profile. We apply Rayleigh's inflection theorem and Fjørtoft's theorem to analyze the stability criteria concluding that this \emph{inner local} instability originates from a shear instability close to the peak of the angular velocity profile, and that it later evolves into a fast-rotating m=2 oscillation pattern. We discuss the importance of the presence of a corotation point in the fluid, its connection with the shear instability, and comparisons to the Rossby wave and Papaloizou Pringle instabilities considered in the wider literature.

Modeling of Cosmic-Ray Production and Transport and Estimation of Gamma-Ray and Neutrino Emissions in Starburst Galaxies

description: Starburst galaxies (SBGs) with copious massive stars and supernova (SN) explosions are the sites of active cosmic-ray production. Based on the predictions of nonlinear diffusive shock acceleration theory, we model the cosmic-ray proton (CRP) production by both pre-SN stellar winds (SWs) and supernova remnants (SNRs) from core-collapse SNe inside the starburst nucleus. Adopting different models for the transport of CRPs, we estimate the $γ$-ray and neutrino emissions due to $pp$ collisions from nearby SBGs such as M82, NGC253, and Arp220. We find that with the current $γ$-rays observations by Fermi-LAT, Veritas, and H.E.S.S., it would be difficult to constrain CRP production and transport models. Yet, the observations are better reproduced with (1) the combination of the single power-law (PL) momentum distribution for SNR-produced CRPs and the diffusion model in which the CRP diffusion is mediated by the strong Kolmogorov-type turbulence of $δB/B\sim1$, and (2) the combination of the double PL model for SNR-produced CRPs and the diffusion model in which the scattering of CRPs is controlled mostly by self-excited waves rather than the pre-existing turbulence. The contribution of SW-produced CRPs could be substantial in Arp220, where the star formation rate is higher and the slope of the initial mass function would be flatter. We suggest that M82 and NGC253 might be detectable as point sources of high-energy neutrinos in the upcoming KM3NET and IceCube-Gen2, when optimistic models are applied. Future observations of neutrinos as well as $γ$-rays would provide constraints for the production and diffusion of CRPs in SBGs.

On the formulation of D=11 supergravity and the composite nature of its three-from field

description: The underlying gauge group structure of the D=11 Cremmer-Julia-Scherk supergravity becomes manifest when its three-form field A_3 is expressed through a set of one-form gauge fields. These are associated with the generators of the elements of a family of enlarged supersymmetry algebras $\tilde{\mathfrak{E}}^{(528|32+32)}(s)$ parametrized by a real number s. We study in detail the composite structure of A_3 extending previous results by D'Auria and Fré, stress the equivalence of the above problem to the trivialization of a standard supersymmetry algebra ${\mathfrak{E}}^{(11|32)}$ cohomology four-cocycle on the enlarged ${\tilde {\mathfrak{E}}}^{(528|32+32)}(s)$ superalgebras, and discuss its possible dynamical consequences. To this aim we consider the properties of the first order supergravity action with a composite A_3 field and find the set of extra gauge symmetries that guarantee that the field theoretical degrees of freedom of the theory remain the same as with a fundamental A_3. The extra gauge symmetries are also present in the so-called rheonomic treatment of the first order D=11 supergravity action when A_3 is composite. Our considerations on the composite structure of A_3 provide one more application of the idea that there exists an extended superspace coordinates/fields correspondence. They also suggest that there is a possible embedding of D=11 supergravity into a theory defined on the enlarged superspace ${\tildeΣ}^{(528|32+32)}(s)$.

description: Resonant inelastic x-ray scattering (RIXS) provides remarkable opportunities to interrogate ultrafast dynamics in liquids. Here we use RIXS to study the fundamentally and practically important hydroxyl radical in liquid water, OH(aq). Impulsive ionization of pure liquid water produced a short-lived population of OH(aq), which was probed using femtosecond x-rays from an x-ray free-electron laser. We find that RIXS reveals localized electronic transitions that are masked in the ultraviolet absorption spectrum by strong charge-transfer transitions -- thus providing a means to investigate the evolving electronic structure and reactivity of the hydroxyl radical in aqueous and heterogeneous environments. First-principles calculations provide interpretation of the main spectral features.

description: In this paper, we explore the link between globalization of the retail sector and the export activity of firms from their origin country. In a previous paper (Cheptea, Emlinger and Latouche, forthcoming), we showed that exporting firm from countries with internationalized retail companies benefit more from this process than firms from other countries. The underlying assumption of this paper is that the main benefits are grasped by the retailers’ domestic suppliers. In other words, firms that sell their products under retailers’ brands benefit more from the overseas expansion of retailers than other firms. We employ French firm-level data to evaluate the effect for the two types of firms. We identify retailers’ suppliers using the certification of French agri-food firms with the private IFS standard, granting them the right to sell their products under a retailer’s brand. Our empirical objective is to estimate whether firms with IFS certification have better export performance on markets where French retail companies have established outlets. We find that certified French firms export more than non-certified firms to markets where IFS retailers established outlets (mainly outside Europe). The difference is statistically significant and robust to the use of firm- and country-specific fixed effects. Results are similar for the extensive and the intensive margin of exports.
Connecting active and passive $\mathcal{PT}$-symmetric Floquet modulation models

description: Open systems with gain, loss, or both, described by non-Hermitian Hamiltonians, have been a research frontier for the past decade. In particular, such Hamiltonians which possess parity-time ($\mathcal{PT}$) symmetry feature dynamically stable regimes of unbroken symmetry with completely real eigenspectra that are rendered into complex conjugate pairs as the strength of the non-Hermiticity increases. By subjecting a $\mathcal{PT}$-symmetric system to a periodic (Floquet) driving, the regime of dynamical stability can be dramatically affected, leading to a frequency-dependent threshold for the $\mathcal{PT}$-symmetry breaking transition. We present a simple model of a time-dependent $\mathcal{PT}$-symmetric Hamiltonian which smoothly connects the static case, a $\mathcal{PT}$-symmetric Floquet case, and a neutral-$\mathcal{PT}$-symmetric case. We analytically and numerically analyze the $\mathcal{PT}$ phase diagrams in each case, and show that slivers of $\mathcal{PT}$-broken ($\mathcal{PT}$-symmetric) phase extend deep into the nominally low (high) non-Hermiticity region.
