description: We introduce interacting particle Markov chain Monte Carlo (iPMCMC), a PMCMC method based on an interacting pool of standard and conditional sequential Monte Carlo samplers. Like related methods, iPMCMC is a Markov chain Monte Carlo sampler on an extended space. We present empirical results that show significant improvements in mixing rates relative to both non-interacting PMCMC samplers, and a single PMCMC sampler with an equivalent memory and computational budget. An additional advantage of the iPMCMC method is that it is suitable for distributed and multi-core architectures.

description: This work is a systematic study of discrete Markov chains that are used to describe the evolution of a two-types population. Motivated by results valid for the well-known Moran (M) and Wright-Fisher (WF) processes, we define a general class of Markov chains models which we term the Kimura class. It comprises the majority of the models used in population genetics, and we show that many well-known results valid for M and WF processes are still valid in this class. In all Kimura processes, a mutant gene will either fixate or become extinct, and we present a necessary and sufficient condition for such processes to have the probability of fixation strictly increasing in the initial frequency of mutants. This condition implies that there are WF processes with decreasing fixation probability --- in contradistinction to M processes which always have strictly increasing fixation probability. As a by-product, we show that an increasing fixation probability defines uniquely an M or WF process which realises it, and that any fixation probability with no state having trivial fixation can be realised by at least some WF process. These results are extended to a subclass of processes that are suitable for describing time-inhomogeneous dynamics. We also discuss the traditional identification of frequency dependent fitnesses and pay-offs, extensively used in evolutionary game theory, the role of weak selection when the population is finite, and the relations between jumps in evolutionary processes and frequency dependent fitnesses.

description: Telescopes, designed with semi-conductor based photo sensors, have the potential to detect Cherenkov or fluorescence light emitted by cosmic-rays in the atmosphere. Such telescopes promise a high duty cycle and efficiency in remote harsh environments. Given the relatively low costs and robustness of these instruments, this technology could prove interesting especially if deployed in large numbers with existing and future extended cosmic-ray and gamma ray detectors, including the Pierre Auger observatory, HAWC, IceCube and CTA. They may have the potential to enhance the sensitivity of these instruments for the detection of high-energy gamma rays and cosmic-ray air showers. In addition, for neutrino telescopes such a technology could prove to be an efficient cosmic-ray veto on the surface. In this contribution the current motivation, design, and development of a prototype SiPM based air Cherenkov telescope is described. The results of initial sensitivity studies, and the readiness of the system for first tests, including those proposed for the South Pole are shown.

Using a general family of testing functions, we obtain new blowup conditions for the relativistic Euler-Poisson equations. We also show that the proposed blowup conditions are valid regardless of the speed requirement, which was one of the key constraints stated in "Y. Geng, Singularity Formation for Relativistic Euler and Euler-Poisson Equations with Repulsive Force, Commun. Pure Appl. Anal., 14 (2015), 549--564.".

description: Context. The properties of hydrogenated amorphous carbon (a-C:H) dust are known to evolve in response to the local conditions. Aims. We present an adaptable model for the determination of the optical properties of low-temperature, interstellar a-C:H grains that is based on the fundamental physics of their composition. Methods. The imaginary part of the refractive index, k, for a-C:H materials, from 50 eV to cm wavelengths, is derived and the real part, n, of the refractive index is then calculated using the Kramers-Kronig relations. Results. The formulated optEC(s) model allows a determination of the complex dielectric function, epsilon, and refractive index, m(n, k), for a-C:H materials as a continuous function the band gap, Eg , which is shown to lie in the range = -0.1 to 2.7 eV. We provide expressions that enable a determination of their optical constants and tabulate m(n, k, Eg ) for 14 different values of Eg . We explore the evolution of the likely extinction and emission behaviours of a-C:H grains and estimate the relevant transformation time-scales. Conclusions. With the optEC(s) model we are able to predict how the optical properties of an a-C:H dust component in the interstellar medium will evolve in response to, principally, the local interstellar radiation field. The evolution of a-C:H materials appears to be consistent with many dust extinction, absorption, scattering and emission properties, and also with H2 molecule, daughter PAH and hydrocarbon molecule formation resulting from its photo-driven decomposition.

description: The study of light-matter interaction has led to many fundamental discoveries as well as numerous important technologies. Over the last decades, great strides have been made in increasing the strength of this interaction at the single-photon level, leading to a continual exploration of new physics and applications. Recently, a major achievement has been the demonstration of the so-called strong coupling regime, a key advancement enabling great progress in quantum information science. Here, we demonstrate light-matter interaction over an order of magnitude stronger than previously reported, reaching the nonperturbative regime of ultrastrong coupling (USC). We achieve this using a superconducting artificial atom tunably coupled to the electromagnetic continuum of a one-dimensional waveguide. For the largest coupling, the spontaneous emission rate of the atom exceeds its transition frequency. In this USC regime, the description of atom and light as distinct entities breaks down, and a new description in terms of hybrid states is required. Our results open the door to a wealth of new physics and applications. Beyond light-matter interaction itself, the tunability of our system makes it a promising tool to study a number of important physical systems such as the well-known spin-boson and Kondo models.

description: We explore the link between soft vibrational modes and local relaxation events in polymer glasses during physical aging, active deformation at constant strain rate, and subsequent recovery. A softness field is constructed out of the superposition of the amplitudes of the lowest energy normal modes, and found to predict up to 70% of the rearrangements. Overlap between softness and rearrangements increases logarithmically during aging and recovery phases as energy barriers rise due to physical aging, while yielding rapidly rejuvenates the overlap to that of a freshly prepared glass. In the strain hardening regime, correlations rise for uniaxial tensile deformation but not for simple shear. These trends can be explained by considering the differing degrees of localization of the soft modes in the two deformation protocols.

description: There is no mind-matter problem in practice: we go with ease between the material world of things and the mental realm of ideas as we think about things and make things we think of (e.g., this abstract). Here we solve the attendant theoretical problem, i.e. we present a conceptual repertoire needed to develop a declarative understanding of conscious participation in the practice of everyday life. We begin with: res extensa vs. res cogitans, and the corresponding dual: change vs. unity. Next, we show how to objectify change, which accounts for the perceptual objectification of physical contrasts into people, things, and their peccadilloes populating our conscious experience. Change, in turn, is natural (or not-a-miracle), i.e., unity-respecting change. We find, in the light of our theory, that the effectiveness of mathematics---understood as the broad objective logic of qualities resulting from quantitative variations---in the natural sciences, which include social, psychological, biological, and physical, is reasonable. We conclude with an application of our theory: show how artificial intelligence (AI) can advance by bridging across the hitherto insurmountable schism: statistical vs. mathematical.

description: Fluctuation theorems have a very special place in the study of non equilibrium dynamics of physical systems. The form in which it is used most extensively is the Gallavoti-Cohen Fluctuation Theorem which is in terms of the distribution of the work $p(W)/p(-W)=\exp(αW)$. We derive the general form of the fluctuation theorems for an arbitrary Gaussian Markov process and find conditions when the parameter $α$ becomes a universal parameter $1/kT$. As an application we consider fluctuation theorems for classical cyclotron motion of an electron in a parabolic potential. The motion of the electron is described by four coupled Langevin equations and thus is non-trivial. The generalized theorems are equally valid for non-equilibrium steady states.

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Context. The properties of hydrogenated amorphous carbon (a-C:H) dust evolve in response to the local radiation field in the interstellar medium and the evolution of these properties is particularly dependent upon the particle size. Aims. A model for finite-sized, low-temperature amorphous hydrocarbon particles, based on the microphysical properties of random and defected networks of carbon and hydrogen atoms, with surfaces passivated by hydrogen atoms, has been developed. Methods. The eRCN/DG and the optEC(s) models have been combined, adapted and extended into a new optEC(s)(a) model that is used to calculate the optical properties of hydrocarbon grain materials down into the sub-nanometre size regime, where the particles contain only a few tens of carbon atoms. Results. The optEC(s)(a) model predicts a continuity in properties from large to small (sub-nm) carbonaceous grains. Tabulated data of the size-dependent optical constants (from EUV to cm wavelengths) for a-C:H (nano-)particles as a function of the bulk material band gap [Eg(bulk)], or equivalently the hydrogen content, are provided. The effective band gap [Eg(eff.)] is found to be significantly larger than Eg(bulk) for hydrogen-poor a-C(:H) nano-particles and their predicted long-wavelength (λ > 30μm) optical properties differ from those derived for interstellar polycyclic aromatic hydrocarbons (PAHs). Conclusions. The optEC(s)(a) model is used to investigate the size-dependent structural and spectral evolution of a-C(:H) materials under ISM conditions, including: the IR-FUV extinction, the 217 nm bump and the infrared emission bands. The model makes several predictions that can be tested against observations.

description: Thermal energy storage is one of the key challenges of the energy transition, since a large portion of the final energy consumption is used for heating purposes and industrial processes and heat is subject to large seasonal fluctuations in supply and demand. To overcome this seasonal mismatch, geothermal storage offers a large, mostly unexploited potential with capacities that are unequalled by other technologies. The technology of high-temperature thermal storage in aquifers has a crucial role to play, since it could serve the need for large storage capacities. We highlight two aquifer types to which we attach a high importance as future technology.

description: We study the geometry of infinite random Boltzmann planar maps with vertices of high degree. These correspond to the duals of the Boltzmann maps associated to a critical weight sequence $(q_{k})_{ k \geq 0}$ for the faces with polynomial decay $k^{-a}$ with $a \in ( 3/2, 5/2)$ which have been studied by Le Gall & Miermont as well as by Borot, Bouttier & Guitter. We show the existence of a phase transition for the geometry of these maps at $a = 2$. In the dilute phase corresponding to $a \in (2, 5/2)$ we prove that the volume of the ball of radius $r$ (for the graph distance) is of order $r^{\mathsf{d}}$ with $\mathsf{d}= (a-1/2)/(a-2)$, and we provide distributional scaling limits for the volume and perimeter process. In the dense phase corresponding to $a \in (3/2,2)$ the volume of the ball of radius $r$ is exponential in $r$. We also study the first-passage percolation (FPP) distance with exponential edge weights and show in particular that in the dense phase the FPP distance between the origin and infinity is finite. The latter implies in addition that the random lattices in the dense phase are transient. The proofs rely on the recent peeling process introduced in arXiv:1506.01590 and use ideas of arXiv:1412.5509 in the dilute phase.

En línea con ello, el presente deja caer su análisis sobre tres pilares: la primera, referida al ciclón de la ira despertado contra el pueblo judío y lo que posteriormente encausaría la creación del Estado de Israel en la tierra de la discordia (Jerusalén). El segundo punto, detiene un breve repaso en las últimas descargas perpetradas por Estados Unidos en la solución biestatal, a cuyo disparo directo llama Pacto del Siglo (2020); y, para ir cerrando, el tercer enclave, recorre de forma acelerada el reinicio de las acciones bélicas en 2021 entre el Estado de Israel y Palestina (Hamás) en el denominado territorio de la colosal cárcel a cielo abierto. Finalmente, en una situación desigual, atrapados en las garras del infierno, todo indica que el quiebre de un país mientras el otro recluta mayor peso harán difícil enfriar o congelar el hiper-conflicto, incluso, bajo la tormenta del COVID-19.

description: Metadynamics is a popular enhanced sampling scheme wherein by periodic application of a repulsive bias, one can surmount high free energy barriers and explore complex landscapes. Recently metadynamics was shown to be mathematically well founded, in the sense that the biasing procedure is guaranteed to converge to the true free energy surface in the long time limit irrespective of the precise choice of biasing parameters. A differential equation governing the post-transient convergence behavior of metadynamics was also derived. In this short communication, we revisit this differential equation, expressing it in a convenient and elegant Riccati-like form. A perturbative solution scheme is then developed for solving this differential equation, which is valid for any generic biasing kernel. The solution clearly demonstrates the robustness of metadynamics to choice of biasing parameters and gives further confidence in the widely used method.

description: TITLE: Attitudes of Health Professions Students in the Philippines Towards Interprofessional Collaboration Purpose: Determining attitudes of health professions students towards interprofessional collaboration (IPC) can help guide curriculum development in interprofessional education (IPE). Methods: The Interprofessional Attitudes Scale (IPAS) was administered to students in their final clinical year of medicine, nursing, pharmacy, medical technology, rehabilitative sciences, and dentistry programs at a private university in the Philippines. Overall and subscale IPAS scores were compared across programs using ANOVA. Results: Positive attitudes were demonstrated by mean scores > 4/5 (agree or strongly agree) for the total IPAS scale and all subscales except for interprofessional bias 3 to 4 (neutral to agree). Post-hoc tests identified that pharmacy and dentistry differed on the patient-centeredness subscale, mean (SD) of 4.57 (0.39) and 4.9 (0.21) respectively, p=.002; no other significant differences were found across professions. Prior work experience in the healthcare field and having a parent or guardian working/had worked in healthcare did not significantly impact scores. Conclusions: A pre-graduation IPAS can serve as a needs assessment and as one measure of the effectiveness of existing IPE efforts and culture. Positive attitudes suggest educators can focus additional IPE efforts on other goals such as attaining specific competencies and skills.

The relationship between grip strength, reaction time, and cerebral white matter integrity in the anterior internal capsule of healthy older adults
Creators: name: Gravitt, Karla
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This study investigated the relationship between grip strength, reaction time, and cerebral white matter integrity (CWMI) in the anterior internal capsule (AIC) of healthy older adults. Gender and hemispheric influences were also explored. Fifteen subjects (8 males, 7 females; 66.2 ± 5.8 years old) completed dynamic grip strength and reaction time testing (recognition and combined) on the dominant hand. Magnetic resonance imaging with diffusion tensor imaging determined CWMI in the AIC via computation of fractional anisotropy (FA) values. A simple regression revealed a positive correlation between grip strength and FA values in the left AIC (r = 0.577; r2 = 0.33, p = 0.039). A positive correlation between combined reaction time and FA values was found in the right AIC (r = 0.688; r2 = 0.47, p = 0.037). No significant gender relationships were noted. The potential hemispheric influence of fitness on CWMI should be further explored.

description: Mean field calculations, based on the D1S, D1N and D1M parametrizations of the Gogny energy density functional, have been carried out to obtain the potential energy surfaces relevant to fission in several Ra isotopes with the neutron number 144 $\le$ N $\le$ 176. Inner and outer barrier heights as well as first and second isomer excitation energies are given. The existence of a well developed third minimum along the fission paths of Ra nuclei, is analyzed in terms of the energetics of the "fragments" defining such elongated configuration. The masses and charges of the fission fragments are studied as functions of the neutron number in the parent Ra isotope. The comparison between fission and $α$-decay half-lives, reveals that the former becomes faster for increasing neutron numbers. Though there exists a strong variance of the results with respect to the parameters used in the computation of the spontaneous fission rate, a change in tendency is observed at N=164 with a steady increase that makes heavier neutron-rich Ra isotopes stable against fission, diminishing the importance of fission recycling in the r-process.

description: The binary system RW Aur consists of two classical T~Tauri stars (CTTSs). The primary recently underwent its second observed major dimming event ($ΔV\,\sim2\,$mag). We present new, resolved Chandra X-ray and UKIRT near-IR (NIR) data as well as unresolved optical photometry obtained in the dim state to study the gas and dust content of the absorber causing the dimming. The X-ray data show that the absorbing column density increased from $N_H<0.1\times10^{22}\,$cm$^{-2}$ during the bright state to $\approx2\times10^{22}\,$cm$^{-2}$ in the dim state. The brightness ratio between dim and bright state at optical to NIR wavelengths shows only a moderate wavelength dependence and the NIR color-color diagram suggests no substantial reddening. Taken together, this indicates gray absorption by large grains ($\gtrsim1\,μ$m) with a dust mass column density of $\gtrsim2\times10^{-4}\,$g$\,$cm$^{-2}$. Comparison with $N_H$ shows that an absorber responsible for the optical/NIR dimming and the X-ray absorption is compatible with the ISM's gas-to-dust ratio, i.e., that grains grow in the disk surface layers without largely altering the gas-to-dust ratio. Lastly, we discuss a scenario in which a common mechanism can explain the long-lasting dimming in RW Aur and recently in AA Tau.

Multiculturalism and expectations of inclusion among European Muslims
Creators: name: Yazdiha, Hajar
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Why do Muslim minorities perceive more societal hostility in European countries with greater multicultural commitments? This paper examines a unique cross-national survey of Muslims in four Western European countries and finds that personal experiences of discrimination and perceptions of societal hostility are more widespread in Britain and France than in Germany and Spain, notwithstanding more multicultural policies and public attitudes in Britain and France. The paper bridges several literatures on immigration and discrimination to account for this puzzle, including social identity theory, which focuses on individual experiences of discrimination; migration studies that focus on the uneven integration of immigrants; and citizenship studies that focus on regimes of incorporation. The paper combines all of these perspectives in proposing that multiculturalism generates expectations of inclusion that make immigrant communities more likely to identify and label discrimination and hostility.
Revolutionary Narrative, Revolutionary Defense: Reading Stalin's First Victim
Creators: name: Guadagnolo, Gary
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: This thesis traces a complex discourse of the self in the early Soviet era, navigating the identities both assumed by and ascribed to Mirsaid Sultan-Galiev (1892-1940), a Volga Tatar and at one time the highest-ranking Muslim in the Communist Party. After the Bolshevik Revolution, Sultan-Galiev balanced a number of influences, most particularly his Tatar nationality, his Muslim culture and faith, and his belief in the objectives of a socialist revolution. Sultan-Galiev strayed too far from ideological orthodoxy, though, which led to his 1923 arrest. Rather than trying to determine Sultan-Galiev's guilt, I assess his attempts to assert his innocence and the consequences of his failure to do so. Drawing on the field of Soviet subjectivities, I analyze the role of narrative in both the defense and vilification of Sultan-Galiev. This was more than just a conflict over policy; it delineated the power of a Soviet subject over his own story.

description: The prevalence of inappropriate prescribing and polypharmacy among the older adults are well documented and known to contribute to substantial proportions of adverse events, healthcare utilisation, poor quality of life and cost to the health system. Older adults with life-limiting illnesses and limited life expectancy are even more vulnerable to these outcomes because of the change in their body physiology due to both ageing and the disease. Hence, medicines which were once beneficial for disease prevention can become less relevant or incur more risk. But evidence suggest that they continue to receive such potentially inappropriate medicines, even at the end-of-life. Consequently, it would be more appropriate to withdraw such medicines under the supervision of health care professionals, a process called deprescribing. By contrast, scarce information is available about the impact of deprescribing of inappropriate medications on the wellbeing of people in the last year of life. In particular, deprescribing of dual-purpose medications i.e. used for prevention and treatment of chronic conditions, have not been widely reported for this specific vulnerable group of population. This review aims to fill this knowledge gap by synthesising information on effectiveness levels and benefits of randomised and non-randomised interventions.

description: It has been suggested that Type II supernovae with rapidly fading light curves (a.k.a. Type IIL supernovae) are explosions of progenitors with low-mass hydrogen-rich envelopes which are of the order of 1 Msun. We investigate light-curve properties of supernovae from such progenitors. We confirm that such progenitors lead to rapidly fading Type II supernovae. We find that the luminosity of supernovae from such progenitors with the canonical explosion energy of 1e51 erg and 56Ni mass of 0.05 Msun can increase temporarily shortly before all the hydrogen in the envelope recombines. As a result, a bump appears in their light curves. The bump appears because the heating from the nuclear decay of 56Ni can keep the bottom of hydrogen-rich layers in the ejecta ionized, and thus the photosphere can stay there for a while. We find that the light-curve bump becomes less significant when we make explosion energy larger (>~ 2e51 erg), 56Ni mass smaller (

Drawing as manual drafting in the interior design industry: A work-based study
Creators: name: Lomas (Student), Elena

description: Since the rise of computer-aided design (CAD) software in the past 20 years, there has been a noticeable decline in student manual drafting abilities. The pervasive use and value of CAD applications are not questioned in this research project because they are the norm in interior design and their contributions have been significant. However, due to the impact of digitalisation on modern interior design education, graduates and students of interior design have shown a limited capacity for producing simple floor plans, elevations, sections, and perspectives by hand.

It can therefore be argued there is a disconnect between professional practice and whether there is value in manual drawing in graduate education. By presenting the opinions of ten professional experts in interior design, this work-based research project explores whether the use of drawing as a manual drafting skill in professional practice is important. The study additionally looks at how experienced interior designers recognise their skills and question the value of drawing as a manual drafting technique.

To generate qualitative data, a series of semi-structured interviews were conducted. The findings from these interviews suggest, that interior designers still rely heavily on manual drafting and drawing as a component of their process for client briefs, concept generation, and communication. Despite ongoing digitalisation, this knowledge will assist students and newly graduated interior designers to use manual drafting to become better communicators, idea generators, and thus ultimately better designers.

The existing literature on this subject suggests that educators need to be aware of opportunities to create new techniques to enhance the delivery of manual drafting skills in tertiary education.
Trafficked women, the garbage can, and frustrated policy: EU failure to combat human trafficking
Creators: name: Carr, Zachary
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This thesis argues that the EU's anti-human trafficking policies have been a failure. The problem of human trafficking can only be effectively addressed at the supranational level. I demonstrate in this study that the garbage can model of institutional choice provides the best explanation for the failure of EU policy. This is demonstrated through a critical assessment EU decision making and policy formation in justice and home affairs, as well as an examination of the outcomes of anti-trafficking policy. The dominant normative approaches to human trafficking do not adequately describe the failure of EU policy. The garbage can model is explained as a result of conditions of organized anarchy within the EU in general and the third pillar in particular. The major finding of this thesis is that in order to combat human trafficking more effectively he EU must redesign its decision making style in justice and home affairs.

Non-Markovian magnetization dynamics for uniaxial nanomagnets

description: A stochastic approach for the description of the time evolution of the magnetization of nanomagnets is proposed, that interpolates between the Landau-Lifshitz-Gilbert and the Landau-Lifshitz-Bloch approximations, by varying the strength of the noise. Its finite autocorrelation time, i.e. when it may be described as colored, rather than white, is, also, taken into account and the consequences, on the scale of the response of the magnetization are investigated. It is shown that the hierarchy for the moments of the magnetization can be closed, by introducing a suitable truncation scheme, whose validity is tested by direct numerical solution of the moment equations and compared to the averages obtained from a numerical solution of the corresponding colored stochastic Langevin equation. This comparison is performed on magnetic systems subject to both an external uniform magnetic field and an internal one-site uniaxial anisotropy.

Reading the body in the narratives of Maria Luisa Bombal
Creators: name: Zink, Alison Kara
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: María Luisa Bombal (Viña del Mar, 1910-1980) was one of the few Latin Americanfemale writers of the 1930s and 1940s whose works received international acclaim. Herworks of fiction include House of Mist (1947), La Última Niebla (1935), El Árbol (1939), La Historia de María Griselda (1946), La Amortajada (1938), and Las Islas Nuevas (1939). Since literary production in Latin America in the first half of the twentieth century was decidedly headlined by male authors, readers were often limited by masculine portrayals of female characters. By focusing on Bombal's female characters this thesis helps to provide some insights into another way of portraying female literary constructions in the 1930s and 40s. Bombal manages to convey through her female characters' postures, actions, and expressions that which would not otherwise be visible or even allowed of these women who mirrored the set notion of women in her time. Their true thoughts, feelings, and emotions are relayed through Bombal's depiction of her protagonists' bodies in response to their surrounding circumstances, and it is to this aspect of characterization that I will devote my project.

description: Double-lobe radio galaxies in the local Universe have traditionally been found to be hosted in elliptical or lenticular galaxies. We report the discovery of four spiral-host double-lobe radio galaxies (J0836+0532, J1159+5820, J1352+3126 and J1649+2635) that are discovered by cross-matching a large sample of 187005 spiral galaxies from SDSS DR7 to the full catalogues of FIRST and NVSS. J0836+0532 is reported for the first time. The host galaxies are forming stars at an average rate of 1.7 $-$ 10 M$_{\odot}$ yr$^{-1}$ and possess Super Massive Black Holes (SMBHs) with masses of a few times 10$^{8}$ M$_{\odot}$. Their radio morphologies are similar to FR-II radio galaxies with total projected linear sizes ranging from 86 kpc to 420 kpc, but their total 1.4 GHz radio luminosities are only in the range 10$^{24}$ $-$ 10$^{25}$ W Hz$^{-1}$. We propose that the formation of spiral-host double-lobe radio galaxies can be attributed to more than one factor, such as the occurrence of strong interactions, mergers, and the presence of unusually massive SMBHs, such that the spiral structures are not destroyed. Only one of our sources (J1649+2635) is found in a cluster environment, indicating that processes other than accretion through cooling flows e.g., galaxy-galaxy mergers or interactions could be plausible scenarios for triggering radio-loud AGN activity in spiral galaxies.
