description: A generally accepted and widely used approach to solving the problem of analyzing a system of the "composition - property" type consists in identifying and selecting a set of factors that presumably affect the value of a certain response function. Such a function characterizes the efficiency of the system's functioning and is usually formalized in the form of a regression equation that is nonlinear in terms of factors, but linear in terms of parameters. Under the conditions of a large number of influencing factors, it is difficult to solve practical problems of this type due to insufficient experimental data. If by artificial orthogonalization of a passive experiment it is possible to solve the problem of independent estimation of the degree of influence of factors and their interactions, then there is no guarantee that the interaction of factors in the selected subdesign of the experiment design is orthogonal to the factors and to each other. The degree of preference for the subdesign will be the higher, the smaller the number of interactions of factors is not orthogonal to factors and to each other. In this regard, it is important to have a substantiated criterion for assessing the quality of a truncated orthogonal subdesign of the design of a full factorial experiment, which characterizes the level of mixing of the influences of factors and their interactions. It is this criterion that is introduced in this work. The proposed technology for the formation of a representative truncated orthogonal subdesign is described on a specific example of a full factorial experiment design N = 26 formed by artificial orthogonalization. As a result, it is shown that the degree of preference for the design is the higher, the higher the order of interaction of factors mixed with the main factors and the smaller the total number of pairs of non-orthogonal columns. The result of the work was the addition of the traditional set of criteria that are usually used when choosing one of the many possible truncated orthogonal subdesigns of the full factorial experiment design with one more criterion that significantly characterizes the quality of the truncated subdesign. The introduced criterion determines the level of mixing of the influences of factors and their interactions on the value of the response function.

description:  Research on body image among men who have sex with men (MSM) has predominantly been approached with the assumption that all MSM conform to a culturally preferred body, and have a high risk of body image concerns leading to risky behaviors and negative health outcomes. Scholars have called for a more nuanced understanding of how MSM engage with their body images. In response, we conducted 30 semi-structured interviews with Vietnamese MSM to explore their perceptions and feelings of their bodies, including their current body, idealized body, and sexually desired body. Inductive thematic analysis was utilized. The findings highlight the diversity and complexity in Vietnamese MSM’s perceptions and feelings about their bodies, which Western measurements of body image and body dissatisfaction might not fully capture. The participants also acknowledge the pressure of physical appearance; however, they do not always conform to the dominant body ideals and have a high risk of body dissatisfaction. We conclude with a call for reframing the approach to gay and bisexual men’s body image to understand better how they navigate complex pressures and make sense of their body image instead of assuming they are at risk of body dissatisfaction.
On a general definition of the squared Brunt-Väisälä Frequency associated with the specific moist entropy potential temperature

description: The squared Brunt-Väisälä Frequency (BVF) is computed in terms of the moist entropy potential temperature recently defined in Marquet (2011). Both homogeneously saturated and non-saturated versions of $N^2$ (the squared BVF) are derived. The method employed for computing these special homogeneous cases relies on the expression of density written as a function of pressure, total water content and specific moist entropy only. The associated conservative variable diagrams are discussed and compared with existing ones. Despite being obtained without any simplification, the formulations for $N^2$ remain nicely compact and are clearly linked with the squared BVF expressed in terms of the adiabatic non-saturated and saturated lapse rates. As in previous similar expressions, the extreme homogeneous solutions for $N^2$ are of course different, but they are not analytically discontinuous. This allows us to define a simple bridging expression for a single general shape of $N^2$, depending only on the basic mean atmospheric quantities and on a transition parameter, to be defined (or parameterized) in connection with the type of application sought. This integrated result remains a linear combination (with complex but purely local weights) of two terms only, namely the environmental gradient of the moist entropy potential temperature and the environmental gradient of the total water content. Simplified versions of the various equations are also proposed for the case in which the moist entropy potential temperature is approximated by a function of both so-called moist-conservative variables of Betts (1973).

description: We study some consequences of coupling supersymmetric theories to (super)gravity. To linear order, the couplings are determined by the energy-momentum supermultiplet. At higher orders, the couplings are determined by contact terms in correlation functions of the energy-momentum supermultiplet. We focus on the couplings of one particular field in the supergravity multiplet, the auxiliary field $M$. We discuss its linear and quadratic (seagull) couplings in various supersymmetric theories. In analogy to the local renormalization group formalism, we provide a prescription for how to fix the quadratic couplings. They generally arise at two-loops in perturbation theory. We check our prescription by explicitly computing these couplings in several examples such as mass-deformed ${\cal N}$ = 4 and in the Coulomb phase of some theories. These couplings affect the Lagrangians of rigid supersymmetric theories in curved space. In addition, our analysis leads to a transparent derivation of the phenomenon known as Anomaly Mediation. In contrast to previous approaches, we obtain both the gaugino and scalar masses of Anomaly Mediation by relying just on classical, minimal supergravity and a manifestly local and supersymmetric Wilsonian point of view. Our discussion naturally incorporates the connection between Anomaly Mediation and supersymmetric $AdS_4$ Lagrangians. This note can be read without prior familiarity with Anomaly Mediated Supersymmetry Breaking (AMSB).

description: An important open question in fundamental physics concerns the nature of spacetime at distance scales associated with the Planck length. The widespread belief that probing such distances necessitates Planck-energy particles has impeded phenomenological and experimental research in this context. However, it has been realized that various theoretical approaches to underlying physics can accommodate Planck-scale violations of spacetime symmetries. This talk surveys the motivations for spacetime-symmetry research, the SME test framework, and experimental efforts in this field.

description: We calculate the static longitudinal polarizability of single-wall carbon nanotubes in the long wavelength limit taking into account spin-orbit effects. We use a four-orbital orthogonal tight-binding formalism to describe the electronic states and the random phase approximation to calculate the dielectric function. We study the role of both the Rashba as well as the intrinsic spin-orbit interactions on the longitudinal dielectric response, i.e. when the probing electric field is parallel to the nanotube axis. The spin-orbit interaction modifies the nanotube electronic band dispersions, which may especially result in a small gap opening in otherwise metallic tubes. The bandgap size and state features, the result of competition between Rashba and intrinsic spin-orbit interactions, result in drastic changes in the longitudinal static polarizability of the system. We discuss results for different nanotube types, and the dependence on nanotube radius and spin-orbit couplings.

description: The current review presents the advantages and health benefits of the fast growing homogenization techniques for improving food processing using the high-speed homogenization (HSH) and the high-pressure homogenization (HPH) to overcome the main problems encountering food manufacturers, merchandizers and end consumers which are the short shelf-life or nonconformity of food products. HSH and HPH are considered as an efficient alternative tool to thermal processes that cause many undesirable effects such as nonenzymatic browning (NEB), off-flavor or degradation of bioactive components. HPH treatment contributes to microbial load reduction and enzyme inactivation with increase of functionality in terms of health effect by increasing bioavailability by favoring the release of bioactive compounds, modified structures of biopolymers with improvement of novel interactions within particles networking. Homogenizers vary according to the purpose needed to achieve. Laboratory Homogenizers provide research and development (R&D) scientists with more experimentation options and capabilities for emulsions, dispersions, cell rupture, and liposomes with the capability of innovations, improve existing products, and more efficient manufacturing. While the Pilot and Industrial Homogenizers offer unique flexibility to meet every customer’s particular requirements in reproducing the same product quality as developed in the laboratory with increasingly higher levels of plant integration with complete automation, controls and data acquisition. Many laboratory and industrial applications were cited here to highlight the significance of this powerful technology.

description: We present results from an extensive spectroscopic survey of field stars in the Small Magellanic Cloud (SMC). 3037 sources, predominantly first-ascent red giants, spread across roughly 37.5 sq. deg, are analysed. The line of sight velocity field is dominated by the projection of the orbital motion of the SMC around the LMC/Milky Way. The residuals are inconsistent with both a non-rotating spheroid and a nearly face on disk system. The current sample and previous stellar and HI kinematics can be reconciled by rotating disk models with line of nodes position angle, theta, ~ 120-130 deg., moderate inclination (i ~ 25-70 deg.), and rotation curves rising at 20-40 km/s/kpc. The metal-poor stars exhibit a lower velocity gradient and higher velocity dispersion than the metal-rich stars. If our interpretation of the velocity patterns as bulk rotation is appropriate, then some revision to simulations of the SMC orbit is required since these are generally tuned to the SMC disk line-of-nodes lying in a NE-SW direction. Residuals show strong spatial structure indicative of non-circular motions that increase in importance with increasing distance from the SMC centre. Kinematic substructure in the north-west part of our survey area is associated with the tidal tail or Counter-Bridge predicted by simulations. Lower line-of-sight velocities towards the Wing and the larger velocities just beyond the SW end of the SMC Bar are probably associated with stellar components of the Magellanic Bridge and Counter-Bridge, respectively. Our results reinforce the notion that the intermediate-age stellar population of the SMC is subject to substantial stripping by external forces.

description: We report the results of Gemini/GMOS long-slit spectroscopic observations along the major and minor axes of the central galaxies in two fossil groups, SDSS J073422.21+265133.9 and SDSS J075828.11+374711.8 (the NGC 2484 group). Spatially resolved kinematics and stellar population parameters (ages, metallicities and $α$-element abundance ratios) derived using ~20 Lick indices are presented. Despite remarkable similarities in their morphologies, photometric properties (luminosity and colour) and kinematics, the two galaxies exhibit significantly different stellar population parameters. SDSS J073422.21+265133.9 exhibits a strong metallicity gradient (Delta[Z/H]/Delta R ~ -0.4) all the way into the centre of the galaxy. It also exhibits an age profile that suggest a relatively recent, centrally concentrated burst of star formation superimposed on an older, more spatially extended population. NGC 2484, a well known X-ray AGN, exhibits a flat core-like structure in its metallicity gradient, but no detectable age gradient. The alpha-element abundance ratio ([E/Fe]) profiles of the two galaxies are also significantly different. SDSS J073422.21+265133.9 exhibits a slightly positive gradient (Delta [E/H]/Delta R ~ 0.1), perhaps again suggesting a more recent central burst of star formation, while NGC 2484 shows a negative gradient (Delta [E/H]/Delta R ~-0.1), indicating that star formation may have happened "inside out". Our analysis of these two galaxies of similar mass, morphology and kinematics therefore suggests two different mechanisms to have been in action during their formation. Consequently, we conclude that the central galaxies of fossil groups can not be considered a homogeneous group with regard to their formation processes or star formation histories.

Specific Heat and Sound Velocity Distinguish the Relevant Competing Phase in the Pseudogap Region of High Temperature Superconductors

description: A great step forward towards the understanding of high temperature superconductors are the variety of experimental results which have led to the wide-spread acceptance of the idea that a phase with a broken symmetry competes with superconductivity in the under-doped region, often called the pseudo-gap region. There are a plethora of suggested phases. The idea, that a broken symmetry phase competes with superconductivity makes thermodynamic sense only if the energy gained due to it is comparable to that gained through the superconducting transition in their co-existence region. Extraordinarily, however, no specific heat signature of a phase transition has been identified at the pseudo-gap temperature $T^*$. We use the recent highly accurate sound-velocity measurements and the best available specific heat measurements in YBa$_2$Cu$_3$O$_{6+δ}$ to show that phase transitions to the universality class of the loop-current ordered state with free-energy reduction similar to the measured superconducting condensation are consistent with the sound velocity and with lack of identifiable observation in the specific heat. We also compare the measured specific heat with some more usual transitions and show that transitions with such symmetry classes can easily be shown by existing specific heat measurements to have energy reduction due to them less than 1/20 the superconducting condensation energy.

description: Temperature dependent high pressure electrical resistivity studies has been carried out on Ba(Fe_{1-x}Ru_{x})_{2}As_{2} single crystals with x = 0.12, 0.26 and 0.35, which correspond to under doped, optimally doped and over doped composition regimes respectively. The evolution of structural/magnetic (T_{S-M}) and superconducting transition (T_(c)) temperatures, with pressure for various compositions have been obtained. The normal state resistivity has been analyzed in terms of a model that incorporates both spin fluctuations and the opening of the gap in the spin density wave (SDW)phase. It is shown that Tc scales with the strength of the spin fluctuation, B, and T_{S-M} scales with the SDW gap parameter, Δ. This provides a prescription for the unification of the composition and pressure induced superconductivity in BaFe2As2.

description: We propose a single-photon frequency converter via a one-dimensional waveguide coupled to a $V$-type atom. The on-demand classical field allows the atom to absorb a photon with a given frequency, then emit a photon with a carried frequency different from the absorbed one. The absorption and re-emission process is formulated as a two-channel scattering process. We study the single-photon frequency conversion mechanism in two kinds of realistic physical system: coupled resonator waveguide with cosine dispersion relation and an optical waveguide with linear dispersion relation respectively. We find that the driving field prefers weak in coupled resonator waveguide but arbitrarily strong in optical waveguide to achieve an optical transfer efficiency.

description: We measured by laser spectroscopy the isotope shifts between naturally-occurring even-isotopes of strontium ions for both the $5s\,\,^2S_{1/2}\to 5p\,\,^2P_{1/2}$ (violet) and the $4d\,\,^2D_{3/2}\to 5p\,\,^2P_{1/2}$ (infrared) dipole-allowed optical transitions. Fluorescence spectra were taken by simultaneous measurements on a two-component Coulomb crystal in a linear Paul trap containing $10^3$--$10^4$ laser-cooled Sr$^+$ ions. The isotope shifts are extracted from the experimental spectra by fitting the data with the analytical solution of the optical Bloch equations describing a three-level atom in interaction with two laser beams. This technique allowed us to increase the precision with respect to previously reported data obtained by optogalvanic spectroscopy or fast atomic-beam techniques. The results for the $5s\,\,^2S_{1/2}\to 5p\,\,^2P_{1/2}$ transition are $ν_{88}-ν_{84}=+378(4)$ MHz and $ν_{88}-ν_{86}=+170(3)$ MHz, in agreement with previously reported measurements. In the case of the previously unexplored $4d\,\,^2D_{3/2}\to 5p\,\,^2P_{1/2}$ transition we find $ν_{88}-ν_{84}=-828(4)$ MHz and $ν_{88}-ν_{86}=-402(2)$ MHz. These results provide more data for stringent tests of theoretical calculations of the isotope shifts of alkali-metal-like atoms. Moreover, they simplify the identification and the addressing of Sr$^+$ isotopes for ion frequency standards or quantum-information-processing applications in the case of multi-isotope ion strings.

description: We study, by means of the model proposed in Del Popolo (2009), the effect of baryon physics on the small scale problems of the CDM model. We show that, using this model, the cusp/core problem, the missing satellite problem (MSP), the Too Big to Fail (TBTF) problem, and the angular momentum catastrophe can be reconciled with observations. Concerning the cusp/core problem, the interaction among dark matter (DM) and baryonic clumps of 1% the mass of the halo, through dynamical friction (DF), is able to flatten the inner cusp of the density profiles. We moreover assume that haloes form primarily through quiescent accretion, in agreement with the spherical collapse model (SCM)-secondary infall model (SIM) prescriptions. The results of this paper follow from the two assumptions above. Concerning the MSP and TBTF problem, applying to the Via Lactea II (VL2) subhaloes a series of corrections similar to those of Brooks et al. (2013), namely applying a Zolotov et al. (2012)-like correction obtained with our model, and further correcting for the UV heating and tidal stripping, we obtain that the number of massive, luminous satellites is in agreement with the number observed in the MW. The model also produces an angular momentum distribution in agreement with observations, that is with the distribution of the angular spin parameter and angular momentum of the dwarfs studied by van den Bosch, Burkert, & Swaters (2001). In conclusion, the small scale problems of the CDM model can all be solved by introducing baryon physics.

description: We study the statics and dynamics of a binary dipolar Bose-Einstein condensate soliton for repulsive inter- and intraspecies contact interactions with the two components subject to different spatial symmetries $-$ distinct quasi-one-dimensional and quasi-two-dimensional shapes - using numerical solution and variational approximation of a three-dimensional mean-field model. The results are illustrated with realistic values of parameters in the binary 164Dy-168Er mixture. The possibility of forming robust dipolar solitons of very large number of atoms make them of great experimental interest. The existence of the solitons is illustrated in terms of stability phase diagrams. Exotic shapes of these solitons are illustrated in isodensity plots. The variational results for statics (size and chemical potential) and dynamics (small oscillation) of the binary soliton compare well with the numerical results. A way of preparing and studying these solitons in laboratory is suggested.

Here, we show, for the first time, that Rydberg atom electromagnetically induced transparency can be used to image microwave electric fields with unprecedented precision. The spatial resolution of the method is far into the sub-wavelength regime. The electric field resolutions are similar to those we have demonstrated in our prior experiments. Our experimental results agree with finite element calculations of test electric field patterns.

description: Has neoliberalism done its time? It’s around this multifaceted question that the collective research seminar (Un)ruling others and the self unfolds. It is an invitation to a crossover between the different disciplines of the social sciences stimulated by their respective and common methodologies. Through critical analysis of empirical data shared at the seminar, the objective is to target, connect and compare the normativity of global governance model resulting from neoliberal policies and practices and how they operate at different scales.This paper examines the conventional chronological divisions in history, such as ancient, medieval, modern, and contemporary periods, within the context of global history. It calls for a reassessment and continued exploration of these divisions. The paper engages in a historiographical perspective, particularly focusing on European history, to assess the evolution of academic periodisations and explore alternative proposals. Furthermore, it investigates the influence of cultural spheres on temporal categorisations, both in terms of national historiographies and the global, connected history approach. The discourse delves into the necessity and epistemology of periodisations, addressing their relevance and connection to broader temporal frameworks. The paper also extends its inquiry into the relationship between history, social sciences, and humanities, particularly in the context of shifting academic landscapes in the United States and France. It emphasises erudition, linguistic diversity, and their distinct roles in shaping historical study. The article concludes by highlighting the ontological subjectivity and epistemological objectivity inherent in discussions of temporal divisions, presenting a nuanced exploration of temporalities within a historical analysis. This study prompts critical reflection on the intersections of chronology, historiography, and cultural contexts, offering insights into the complexities of temporal frameworks in historical research.

description: The upcoming 5G and beyond wireless systems aim to support billions of devices and handle data traffic 1000 times greater than current 4G systems. Researchers are focusing on two main directions for achieving 6G goals: (1) targeting higher frequency bands to develop new, efficient physical layer techniques, and (2) deploying more active nodes (e.g., antennas, reflecting surfaces) in a given area. Physical layer advancements include shifting from millimeter waves to sub-Terahertz frequencies, utilizing ultra-massive MIMO beamforming for multiple parallel users, and designing new multi-carrier waveforms for better spectral efficiency and reliable wireless links. This thesis concentrates on the first direction, particularly channel modeling, beamforming, and parameter estimation for outdoor sub-THz mobile communication systems, addressing the ultra-reliable, high-mobility communication and high data traffic needs of beyond 5G networks.
3.5 keV X-ray Line Signal from Decay of Right-Handed Neutrino due to Transition Magnetic Moment

Year: 2014

description: We consider the dark matter model with radiative neutrino mass generation where the Standard Model is extended with three right-handed singlet neutrinos ($N_1$, $N_2$ and $N_3$) and one additional SU(2)$_L$ doublet scalar $η$. One of the right-handed neutrinos ($N_1$), being lightest among them, is a leptophilic fermionic dark matter candidate whose stability is ensured by the imposed $\mathbb{Z}_2$ symmetry on this model. The second lightest right-handed neutrino ($N_2$) is assumed to be nearly degenerated with the lightest one enhancing the co-annihilation between them. The effective interaction term among the lightest, second lightest right-handed neutrinos and photon containing transition magnetic moment is responsible for the decay of heavier right-handed neutrino to the lightest one and a photon ($N_2\to N_1 + γ$). This radiative decay of heavier right-handed neutrino %to the the lightest one with charged scalar and leptons in internal lines could explain the X-ray line signal $\sim$ $3.5$ keV recently claimed by XMM-Newton X-ray observatory from different galaxy clusters and Andromeda galaxy (M31). The value of the transition magnetic moment is computed and found to be several orders of magnitude below the current reach of various direct dark matter searches. The other parameter space in this framework in the light of the observed signal is further investigated.

description: One quarter of all nearby early-type galaxies (ETGs) outside Virgo host a disc/ring of HI with size from a few to tens of kpc and mass up to ~1e+9 solar masses. Here we investigate whether this HI is related to the presence of a stellar disc within the host making use of the classification of ETGs in fast and slow rotators (FR/SR). We find a large diversity of HI masses and morphologies within both families. Surprisingly, SRs are detected as often, host as much HI and have a similar rate of HI discs/rings as FRs. Accretion of HI is therefore not always linked to the growth of an inner stellar disc. The weak relation between HI and stellar disc is confirmed by their frequent kinematical misalignment in FRs, including cases of polar and counterrotating gas. In SRs the HI is usually polar. This complex picture highlights a diversity of ETG formation histories which may be lost in the relative simplicity of their inner structure and emerges when studying their outer regions. We find that LCDM hydrodynamical simulations have difficulties reproducing the HI properties of ETGs. The gas discs formed in simulations are either too massive or too small depending on the star formation feedback implementation. Kinematical misalignments match the observations only qualitatively. The main point of conflict is that nearly all simulated FRs and a large fraction of all simulated SRs host corotating HI. This establishes the HI properties of ETGs as a novel challenge to simulations.

description: The massive interacting close binary system V729 Cyg (OIa+O/WN9), plausibly progenitor of a Wolf-Rayet system, is studied using new observations gathered over 65 nights and earlier published data. Radial velocity and five colour light curves are analysed simultaneously. Estimated physical parameters of the components are $M_1 = 36\pm 3 M_{\odot}$, $M_2 = 10 \pm 1 M_{\odot}$, $R_1 = 27\pm 1 R_{\odot}$, $R_2 = 15 \pm 0.6 R_{\odot}$, $\log{(L_1/L_{\odot})} = 5.59\pm 0.06$, and $\log{(L_2/L_{\odot})} = 4.65\pm 0.07$. We give only the formal 1$σ$ scatter, but we believe systematic errors in the luminosities, of uncertain origin as discussed in the text, are likely to be much bigger. The distance of the Cygnus OB2 association is estimated as $967\pm 48$ pc by using our newly obtained parameters.

description: Two-dimensional transition-metal dichalcogenides (TMDs) are gaining increasing attention as alternative to graphene for their very high potential in optoelectronics applications. Here we consider two prototypical metallic 2D TMDs, NbSe$_2$ and TaS$_2$. Using a first-principles approach, we investigate the properties of the localised intraband $d$ plasmon that cannot be modelled on the basis of the homogeneous electron gas. Finally, we discuss the effects of the reduced dimensionality on the plasmon dispersion through the interplay between interband transitions and local-field effects. This result can be exploited to tune the plasmonic properties of these novel 2D materials.

description: We study Doppler velocity measurements at multiple heights in the solar atmosphere using a set of six filtergrams obtained by the Helioseismic magnetic Imager on board the Solar Dynamics Observatory. There are clear and significant phase differences between core and wing Dopplergrams in the frequency range above the photospheric acoustic cutoff frequency, which indicates that these are really "multi-height" datasets.

Joint probabilistic forecasting of wind speed and temperature using Bayesian model averaging

description: Ensembles of forecasts are typically employed to account for the forecast uncertainties inherent in predictions of future weather states. However, biases and dispersion errors often present in forecast ensembles require statistical post-processing. Univariate post-processing models such as Bayesian model averaging (BMA) have been successfully applied for various weather quantities. Nonetheless, BMA and many other standard post-processing procedures are designed for a single weather variable, thus ignoring possible dependencies among weather quantities. In line with recently upcoming research to develop multivariate post-processing procedures, e.g., BMA for bivariate wind vectors, or flexible procedures applicable for multiple weather quantities of different types, a bivariate BMA model for joint calibration of wind speed and temperature forecasts is proposed based on the bivariate truncated normal distribution. It extends the univariate truncated normal BMA model designed for post-processing ensemble forecast of wind speed by adding a normally distributed temperature component with a covariance structure representing the dependency among the two weather quantities. The method is applied to wind speed and temperature forecasts of the eight-member University of Washington mesoscale ensemble and of the eleven-member ALADIN-HUNEPS ensemble of the Hungarian Meteorological Service and its predictive performance is compared to that of the general Gaussian copula method. The results indicate improved calibration of probabilistic and accuracy of point forecasts in comparison to the raw ensemble and the overall performance of this model is able to keep up with that of the Gaussian copula method.

description: Phoretic self-propulsion is a unique example of force- and torque-free motion on small scales. The classical framework describing the flow field around a particle swimming by self-diffusiophoresis neglects the advection of the solute field by the flow and assumes that the chemical interaction layer is thin compared to the particle size. In this paper we quantify and characterize the effect of solute advection on the phoretic swimming of a sphere. We first rigorously derive the regime of validity of the thin-interaction layer assumption at finite values of the Péclet number (Pe). Within this assumption, we solve computationally the flow around Janus phoretic particles and examine the impact of solute advection on propulsion and the flow created by the particle. We demonstrate that although advection always leads to a decrease of the swimming speed and flow stresslet at high values of the Péclet number, an increase can be obtained at intermediate values of Pe. This possible enhancement of swimming depends critically on the nature of the chemical interactions between the solute and the surface. We then derive an asymptotic analysis of the problem at small Pe allowing to rationalize our computational results. Our computational and theoretical analysis is accompanied by a parallel study of the role of reactive effects at the surface of the particle on swimming (Damköhler number).

description: We found new signatures of the dynamical Casimir effect (DCE) in the context of superconducting circuits. We show that if the recent experiment made by Wilson {\it et al}, which brought the DCE into reality for the first time, is repeated with slight modifications (for instance, different values for the capacitance of the SQUID), three remarkable results will show up, namely: {\it (i)} a quite different spectral distribution for the created particles, deviating from the typical parabolic shape; {\it (ii)} an enhancement by a factor of approximately $5 \times 10^3 $ in the number of created particles with half driven frequency of the effective moving mirror and {\it (iii)} an enhancement by a factor of $3 \times 10^2$ in the particle creation rate. These results may guide the experimentalists in their search for alternative routes to observe the DCE in future experiments.

description: Abies-sukuun kuuluu noin 50 lajia ja luontaisesti ne kasvavat pohjoisen pallonpuoliskon viileällä ja lauhkealla ilmastoalueella (http://www.discoverlife.org). Ne ovat ekologisesti tärkeitä lajeja luontaisella levinnäisyysalueellaan. Niitä kasvatetaan myös luontaisen levinnäisyysalueensa ulkopuolella.  Kauneutensa takia pihdat ovat hyviä koristepuita. Kartiomaisen muotonsa, värinsä, tukevien oksiensa ja neulasten varisemattomuuden ansioista ne ovat oivallisia joulukuusia, joiksi niitä myös kasvatetaan. Euroopassa yleisin joulukuusena kasvatettu laji on kaukasianpihta (Abies nordmanniana) kun taas USAssa virginianpihta (A. fraseri) ja aitopihta (A. procera) ovat suosittuja.  Muita joulukuusiksi kasvatettuja pihtoja ovat palsamipihta (A. balsamea), jättipihta (A. grandis), koreanpihta (A.koreana), siperianpihta (A. sibirica), lännenpihta (A. lasiocarpa), turkinpihta (A. bornmuelleriana), ja harmaapihta (A. concolor). Aitopihta on myös erittäin suosittu laji kaupallisessa joulukuusituotannossa paitsi USAssa myös Euroopassa.
