description: Three populations of Arctic char (Salvelinus alpinus [Linnaeus]) in the Babbage River system, Yukon Territory, had meristic characters that corresponded to those of the Western Arctic-Bering Sea form of the Arctic char. These populations consisted of: 1. Self-perpetuating non-anadromous Arctic char isolated in the spring-fed headwaters of the Babbage River; 2. non-anadromous Arctic char below a waterfall on the Babbage River which are derived from the isolated population; 3. a dimorphic population (anadromous males and females and mature non-anadromous males) utilizing Fish Hole Creek, a spring-fed tributary to the Babbage River . Three life-history patterns occur among these populations: anadromy , self- perpetuating non-anadromy, and non-anadromy in which only mature males are present. The non-anadromous Arctic char are characterized by small size (maximum 395 mm), low growth rates and low fecundities (maximum 653 eggs). Mature fish were darkly pigmented and parr marks and spawning colouration were retained throughout life . The spawning season appears to be in the fall (mid-September to mid- October) with the possibility of earlier spawning (August) occurring in the spring channels in the upper Babbage River. The non-anadromous populations (including the mature nonnnadromous males in Fish Hole Creek) demonstrate inherent differences in growth rates, age at maturity, longevity, peak spawning activity and meristic characters. There are substantial differences between the anadromous and nonanadromous populations in growth rate, age at maturity, fecundity and food habits. The former are characterized by large size (maximum 629 mm), relatively fast growth rate, high fecundity (maximum 5151 eggs) and repeat spawning after maturity. Post-spawning mortality is not indicated and spawning colouration is seasonal. The spawning season appeared to be sometime between mid- September and late October, when the eggs of mature females averaged 4.4 mm in diameter. Some meristic characters (first arch gillraker and vertebral counts) varied significantly between the anadromous ATctic char and the self-perpetuating non-anadromous Arctic char in the upper and lower Babbage River. The available meristic and life-history data suggest that the non-anadromous Arctic char populations do not differ appreciably from other populations of Western Arctic char and do not warrant classification as a distinct species.

description: The last twenty has seen our reliance on digital technology for the practice of art history grow alongside the emergence of what is called the digital humanities. Yet the discourse around digital humanities has thus far failed to articulate, explicitly or consistently, the true stakes of technologies’ influence on the humanities, much less art history. This article therefore seeks to reframe the debate. It argues that we should focus not on the digital or the computer, but instead on the but instead on the dynamic interrelationship between the institutions and domains responsible for the management of art historical information and those of the production of art historical knowledge. More specifically, it examines how recent technological developments are shifting priorities and processes within such institutions and thus shaping and reshaping art-historical practice.

description: Facial Expression Classification is an interesting research problem in recent years. There are a lot of methods to solve this problem. In this research, we propose a novel approach using Canny, Principal Component Analysis (PCA) and Artificial Neural Network. Firstly, in preprocessing phase, we use Canny for local region detection of facial images. Then each of local region's features will be presented based on Principal Component Analysis (PCA). Finally, using Artificial Neural Network (ANN)applies for Facial Expression Classification. We apply our proposal method (Canny_PCA_ANN) for recognition of six basic facial expressions on JAFFE database consisting 213 images posed by 10 Japanese female models. The experimental result shows the feasibility of our proposal method.

description: A preliminary investigation of the ecology of three subalpine streams, Twin Creek, Cabin Creek and Middle Fork Creek, situated on the eastern slopes of the Rocky Mountains, Alberta was carried out during the period June 1974-March 1976. · The annual (1975) average number of invertebrates per square metre was 3,003 and 1,459 in Twin Creek and Cabin Creek respectively . The annual (1975) average standing crop (wet weight) of invertebrates was 9.17 g m- 2 and 3.01 g m-2 in Twin Creek and Cabin Creek respectively. There was a greater diversity (H') of invertebrates in Twin Creek than in Cabin Creek. Oreogeton sp. (Diptera: Empididae) was the most abundant organism in Cabin Creek, whereas Nemoura columbiana (Plecoptera: Filipalpia) was the most abundant invertebrate in Twin Creek. Harvesting of 50% of the for est in Cabin Creek watershed in September 1974 had no obvious effect on the benthic invertebrate community of Cabin Creek. In 1975 adults of 24 species of Plecoptera, 15 species of Trichoptera and 6 species of Ephemeroptera were coll ected within the Ma n~ot Basin watershed. The Plecoptera exhibited a di stinct seasonal succession of emergence from February to October, the Trichoptera were found flying from May to October, while the Ephemeroptera emerged during the months July to October . During the fall and winter of 1975, the breakdown of willow leaves (Salix gZauca x myrtiZZifoZia) in Twin Creek and Cabin Creek was investigated. The fall/winter decay coefficient (k/day-1 ) was 0.0216 and 0.0036 in Twin Creek and Cabin Creek respectively. Both microbial decomposition and invertebrate feeding on the leaves was significantly greater in Twin Creek than in Cabin Creek. It was estimated that invertebrate feeding accounted for 45% of the dry weight lost from the leaves in Twin Creek and nymphs of the stonefly Nemoura coZumbiana played a major role in the breakdown of leaf material in this creek. The low concentration of dissolved orthophosphate may be a factor limiting the decomposition process in Cabin Creek. From August 1975 to October 1976 the periphyton biomass in Twin Creek, Middle Fork Creek and Cabin Creek was determined using the chlorophyll 'a' technique. The mean annual biomass of chlorophyll 'a' was 0.033 g ~-2 ,o~023 g m:2 and 0.007gm-2 in Twin Creek, Middle Fork Creek and Cabin Creek respectively. In Twin Creek and Middle Fork Creek the biomass of chlorophyll 'a' exhibited distinct maxima in June and November/December. Experiments indicated that the calcareous substrate of Cabin Creek may , in part, be responsible for the low p 0 - i phyton biomass in this creek.

To this end, the coupled channel form of the integral relations derived from the Kohn variational principle is used. The construction of degenerate bound-state-like wave functions belonging to the continuum spectrum of the Hamiltonian is discussed. Examples are shown using realistic nucleon-nucleon forces.

description: GRB 170817A, the first short gamma-ray burst (sGRB) to be detected in coincidence with a gravitational wave signal, demonstrated that merging binary neutron star (BNS) systems can power collimated ultra-relativistic jets and, in turn, produce sGRBs. Moreover, it revealed that sGRB jets possess an intrinsic angular structure that is imprinted in the observable prompt and afterglow emission. Advanced numerical simulations represent the leading approach to investigate the physical processes underlying the evolution of sGRB jets breaking out of post-merger environments, and thus connect the final angular structure and energetics with specific jet launching conditions. In a previous paper, we carried out the first three-dimensional (3D) special-relativistic hydrodynamic simulations of incipient (top-hat) sGRB jets propagating across the realistic environment resulting from a general-relativistic (GR) hydrodynamic BNS merger simulation. While the above work marked an important step toward a consistent end-to-end description of sGRB jets from BNS mergers, those simulations did not account for the presence of magnetic fields, which are expected to play a key role. Here, we overcome this limitation, reporting the first 3D special-relativistic magnetohydrodynamic (MHD) simulation of a magnetized (structured and rotating) sGRB jet piercing through a realistic magnetized post-merger environment, wherein the initial conditions of the latter are directly imported from the outcome of a previous GRMHD BNS merger simulation.

description: In preparation for the HERMES chemical tagging survey of about a million Galactic FGK stars, we estimate the number of independent dimensions of the space defined by the stellar chemical element abundances [X/Fe]. [...] We explore abundances in several environments, including solar neighbourhood thin/thick disk stars, halo metal-poor stars, globular clusters, open clusters, the Large Magellanic Cloud and the Fornax dwarf spheroidal galaxy. [...] We find that, especially at low metallicity, the production of r-process elements is likely to be associated with the production of alpha-elements. This may support the core-collapse supernovae as the r-process site. We also verify the over-abundances of light s-process elements at low metallicity, and find that the relative contribution decreases at higher metallicity, which suggests that this lighter elements primary process may be associated with massive stars. [...] Our analysis reveals two types of core-collapse supernovae: one produces mainly alpha-elements, the other produces both alpha-elements and Fe-peak elements with a large enhancement of heavy Fe-peak elements which may be the contribution from hypernovae. [...] The extra contribution from low mass AGB stars at high metallicity compensates the dimension loss due to the homogenization of the core-collapse supernovae ejecta. [...] the number of independent dimensions of the [X/Fe]+[Fe/H] chemical space in the solar neighbourhood for HERMES is about 8 to 9. Comparing fainter galaxies and the solar neighbourhood, we find that the chemical space for fainter galaxies such as Fornax and the Large Magellanic Cloud has a higher dimensionality. This is consistent with the slower star formation history of fainter galaxies. [...]

description: We show that the Wilsonian formulation of the renormalization group (RG) defines a quantum channel acting on the momentum-space density matrices of a quantum field theory. This information theoretical property of the RG allows us to derive a remarkable consequence for the vacuum of theories at a fixed point: they have no entanglement between momentum scales. Our result can be understood as deriving from the scale symmetry of such theories and leads to constraints on the form of the ground state and on expectation values of momentum space operators.

description: Different numerical approaches for the stray-field calculation in the context of micromagnetic simulations are investigated. We compare finite difference based fast Fourier transform methods, tensor grid methods and the finite-element method with shell transformation in terms of computational complexity, storage requirements and accuracy tested on several benchmark problems. These methods can be subdivided into integral methods (fast Fourier transform methods, tensor-grid method) which solve the stray field directly and in differential equation methods (finite-element method), which compute the stray field as the solution of a partial differential equation. It turns out that for cuboid structures the integral methods, which work on cuboid grids (fast Fourier transform methods and tensor grid methods) outperform the finite-element method in terms of the ratio of computational effort to accuracy. Among these three methods the tensor grid method is the fastest. However, the use of the tensor grid method in the context of full micromagnetic codes is not well investigated yet. The finite-element method performs best for computations on curved structures.

description: We introduce a method for global optimization of the structure of atomic systems that uses additional atoms with fractional existence. The method allows for movement of atoms over long distances bypassing energy barriers encountered in the conventional position space. The method is based on Gaussian processes, where the extrapolation to fractional existence is performed with a vectorial fingerprint. The method is applied to clusters and two-dimensional systems, where the fractional existence variables are optimized while keeping the atomic positions fixed on a lattice. Simultaneous optimization of atomic coordinates and existence variables is demonstrated on copper clusters of varying size. The existence variables are shown to speed up the global optimization of large and particularly difficult-to-optimize clusters.

description: Integral field spectroscopic studies of galaxies in dense environments, such as clusters and groups of galaxies, have provided new insights for understanding how star formation proceeds, and quenches. I present the spatially resolved view of the star formation activity and its link with the multiphase gas in cluster galaxies based on MUSE and multi-wavelength data of the GASP survey. I discuss the link among the different scales (i.e. the link between the spatially resolved and the global star formation rate-stellar mass relation), the spatially resolved signatures and the quenching histories of jellyfish (progenitors) and post-starburst (descendants) galaxies in clusters. Finally, I discuss the multi-wavelength view of star-forming clumps both in galaxy disks and in the tails of stripped gas.

description: The ecology of mountain whitefish (Prosopium williamsoni) in the Sheep River, Alberta, was studied to determine its life history which was used as a basis for management recommendations. The study has elucidated the complex movements undertaken by the mountain whitefish, characterized by spring feeding, summer feeding, prespawning, spawning and post-spawning (overwintering) movements. A definite downstream prespawning and spawning movement has been shown with some fish moving in excess of 60 km in a two-week period . The spring feeding, summer feeding and post-spawning movements were identified but not quantified. There were indications that segments of the population of mountain whitefish in the Sheep River were non-migrant and do not undertake any movements in their adult lives. Some adults tagged in a particular location were repeatedly captured in exactly the same location over a period up to one year later. However, the majority of mountain whitefish appeared to be migratory and they moved downstream out of the upper Sheep River in September and October during prespawning, spawning and post-spawning movements. This resulted in an almost complete depopulation of the mountain whitefish population by adults in the upper Sheep River. They moved back into the upper Sheep River around the first of July. A movement to the upper Sheep River by non-adult mountain whitefish in October after the adults had moved downstream was indicated but not quantified. Recruitment to the population in the upper Sheep River took place at 2+ and 3+ years of age. It is possible that recruitment could take place at l+ or even O+ years of age, except a weir across the Sheep River at Turner Valley prevented these two year classes from moving upstream in September and October. A need to provide a fish passage facility at the weir was indicated. The diets of mountain whitefish consisted primarily of dipterans, ephemeropterans, trichopterans and terrestrial invertebrates. Growth is rapid except in the older age classes of 7+ and 8+. No mountain whitefish older than 8+ were collected in the Sheep River. The male mountain whitefish first matured at 3+ years of age while the females first matured at 4+ years of age. In the upper Sheep River, spawning took place in shallow, fast, midstream areas. The number of spawning fish on each spawning site was small (two to 20 fish per site). Spawning started in late September and continued to late October. The majority of spawning occurred between October 4 to October 10, 1973. The spawning substrate in the upper Sheep River was rock and rubble. Spawning took place in the lower Sheep River but the spawning sites ~re not identified. There were indications, however, that the number of spawning fish on probable spawning sites in the lower Shee~ River was large (approximately 500 fish).

description: Large projects often late or over budget, and while there are many reasons, power is one. This thesis argues that those in power can make poor decisions and set up structures to influence the behaviour of project managers charged with implementing those decisions. Some project managers are inclined to comply despite feeling uncomfortable with those poor decisions, so establishing social norms that puts pressure on others who would resist. Resistance is vital if poor decision making by those in power is to be contained, and project performance improved as a result.

description: Recently, ATLAS and CMS experiments at the LHC put on light the relevant results in the measurement precision of the Higgs and BSM. In such a report, where the resonance direct search was made in the $γZ$ channel, a mass adjustment distribution for the reconstructed $Z$ boson and photon was established. Thus, simultaneously with the signal-from-background separation, the number of events has been perfectly described, and an excess signal approximately twice that expected by the Standard Model (SM) has been noticed, which is equivalent to a significance of 2.2 standard deviations. In this study, we examine how any possible new physics models can explain this excess, such as the CP-conserving Two-Higgs doublet model (2HDMs), the Inert doublet model (IDM), and the Higgs triplet model (HTM). While considering the available theoretical and most recent experimental constraints, the phenomenological implications of existing extensions beyond the SM are discussed, and prospects for precision studies of these processes are described. We have found that the excess could be explained in the BSM framework studied, depending on the charged and double-charged Higgs boson masses.

description: We have mapped at small spatial scales the temperature and the velocity field in the protocluster associated with IRAS 05345+3157, which contains both intermediate-/high-mass protostellar candidates and starless condensations, and is thus an excellent location to investigate the role of massive protostars on protocluster evolution. We observed the ammonia (1,1) and (2,2) inversion transitions with the VLA. Ammonia is the best thermometer for dense and cold gas, and the observed transitions have critical densities able to trace the kinematics of the intracluster gaseous medium. The ammonia emission is extended and distributed in two filamentary structures. The starless condensations are colder than the star-forming cores, but the gas temperature across the whole protocluster is higher (by a factor of ~1.3-1.5) than that measured typically in both infrared dark clouds and low-mass protoclusters. The non-thermal contribution to the observed line broadening is at least a factor of 2 larger than the expected thermal broadening even in starless condensations, contrary to the close-to-thermal line widths measured in low-mass quiescent dense cores. The NH3-to-N2H+ abundance ratio is greatly enhanced (a factor of 10) in the pre--stellar core candidates, probably due to freeze-out of most molecular species heavier than He. The more massive and evolved objects likely play a dominant role in the physical properties and kinematics of the protocluster. The high level of turbulence and the fact that the measured core masses are larger than the expected thermal Jeans masses indicate that turbulence likely was an important factor in the initial fragmentation of the parental clump.

Super-Dispersive Demultiplexer Design Using Positive-Negative Refraction Boundary and Hetero-Photonic Crystals

description: In this paper, a systematic approach is employed to design a photonic crystal with a boundary between positive and negative refraction to boost the refractive properties of the crystal. Mathematical techniques are employed to turn the process of EFC engineering into a nearly mechanical process free of trial-and-error steps. The designed demultiplexers operational characteristics are then further improved by adding a second photonic crystal with an oblique boundary. The refracted beams in the first crystal impinge on an oblique interface of the second photonic crystal to experience a change in Bloch wavenumbers and even greater refraction angles so that a novel super-dispersive two-step optical demultiplexer is made. A beam divergence of 161 degrees is obtained for an input spectrum of λ= [1474nm, 1550nm].

description: We state and prove a generalization of Kingman's ergodic theorem on a measure-preserving dynamical system $(X,\mathcal{F},μ,T)$ where the $μ$-almost sure subadditivity condition $f_{n+m} \leq f_n + f_m \circ T^{n}$ is relaxed to a $μ$-almost sure, "gapped", almost subadditivity condition of the form $f_{n+σ_m+m} \leq f_n +ρ_n + f_m \circ T^{n+σ_n}$ for some nonnegative $ρ_n \in L^1(\mathrm{d}μ)$ and $σ_n \in \mathbf{N} \cup \{0\}$ that are suitably sublinear in $n$. This generalization has a first application to the existence of specific relative entropies for suitably decoupled measures on one-sided shifts.
An Almost-FLRW Universe as the Averaged Geometry in Macroscopic Gravity

description: It is well-known that spacetime averaging is an operation that does not commute with building the Einstein tensor. In the framework of Macroscopic gravity (MG), a covariant averaging procedure, this non-commutativity gives averaged field equations with an additional correction term known as back-reaction. It is important to explore whether such a term, even if known to be small, may or may not cause any systematic effect for precision cosmology. In this work, we explore the application of the MG formalism to an almost Friedmann-Lemaître-Robertson-Walker (FLRW) model. Namely, we find solutions to the field equations of MG taking the averaged universe to be almost-FLRW modelled using a linearly perturbed FLRW metric. We study several solutions with different functional forms of the metric perturbations including plane waves ansatzes. We find that back-reaction terms are present not only at the background level but also at perturbed level, reflecting the non-linear nature of the averaging process. Thus, the averaging effect can extend to both the expansion and the growth of structure in the universe.

description: We present a modified complex-valued Shimizu -- Morioka system with uniformly hyperbolic attractor. The numerically observed attractor in Poincaré cross-section is topologically close to Smale -- Williams solenoid. The arguments of the complex variables undergo Bernoulli-type map, essential for Smale -- Williams attractor, due to the geometrical arrangement of the phase space and an additional perturbation term. The transformation of the phase space near the saddle equilibrium "scatters" trajectories to new angles, then trajectories run from the saddle and return to it for the next "scatter". We provide the results of numerical simulations of the model and demonstrate typical features of the appearing hyperbolic attractor of Smale -- Williams type. Importantly, we show in numerical tests the transversality of tangent subspaces -- a pivotal property of uniformly hyperbolic attractor.

description: Let $S(ρ)$ be the von Neumann entropy of a density matrix $ρ$. Weak monotonicity asserts that $S(ρ_{AB}) - S(ρ_A) + S(ρ_{BC}) - S(ρ_C)\geq 0$ for any tripartite density matrix $ρ_{ABC}$, a fact that is equivalent to the strong subadditivity of entropy. We prove an operator inequality, which, upon taking an expectation value with respect to the state $ρ_{ABC}$, reduces to the weak monotonicity inequality. Generalizations of this inequality to the one involving two independent density matrices, as well as their Rényi-generalizations, are also presented.

description: A corpus-based academic grammar of German is an enormous undertaking, especially if it aims at using state-of-the-art methodology while ensuring that its study results are verifiable. The Bausteine-series, which is being developed at the Leibniz Institute for the German Language (IDS), presents individual “building blocks” for such a grammar. In addition to the peer-reviewed texts, the series publishes the results of statistical analyses and, for selected topics, the underlying data sets.

description: Drug discovery is the process of identifying compounds which have potentially meaningful biological activity. A major challenge that arises is that the number of compounds to search over can be quite large, sometimes numbering in the millions, making experimental testing intractable. For this reason computational methods are employed to filter out those compounds which do not exhibit strong biological activity. This filtering step, also called virtual screening reduces the search space, allowing for the remaining compounds to be experimentally tested. In this paper we propose several novel approaches to the problem of virtual screening based on Canonical Correlation Analysis (CCA) and on a kernel-based extension. Spectral learning ideas motivate our proposed new method called Indefinite Kernel CCA (IKCCA). We show the strong performance of this approach both for a toy problem as well as using real world data with dramatic improvements in predictive accuracy of virtual screening over an existing methodology.

Survival from disaster : interdependencies management in critical infrastructure networks
Creators: name: Mao, DeTao
Publisher: name: University of British Columbia
Year: 2009

description: Today's critical infrastructure networks are becoming increasingly interdependent. The complexity of these interdependencies has created a new dimension of vulnerability, making the whole system very fragile under unexpected events. To make the whole system more resilient during disasters, the Joint Infrastructure Interdependencies Research Program (JIIRP), aimed at developing methods for reducing its vulnerabilities. As part of the research work in JIIRP, this thesis mainly consists of three sections: (I) Interdependencies Control Strategy (ICS): Since to prevent all vulnerabilities would be intractable, an interdependencies control strategy, which can help to maintain the survival of the critical service(s) is proposed in Chapter 2. A generalized adjacency matrix (GAM) is proposed to represent the physical interdependencies among infrastructure networks. By computation of GAM, decision making for ICS can be made more effective. Moreover, measures for improving survivability of the system are proposed. ICS application to a case study at the UBC campus is detailed in Chapter 3, its effectiveness during the response stage and the recovery stage of the emergency management cycle are demonstrated. (II) Identification of Cascading Pathways for Mitigating Snow-Caused Power Outages: Since most of the present de-icing and anti-icing methods are not fully developed for industrial applications, building a power network that can tolerate any snow storm would be infeasible. In Chapter 4, based on investigation of Vancouver's power outage in November 2006, a dependency network has been built to represent how the cascading pathways unfolded during this disaster. The effects of a changed climate, the causalities and their consequences are illustrated by this model. Through analyses of the dependency network, we propose a systematic strategy to mitigate the impacts of a snow storm to power systems. (III) Contributions to I2Sim: I2Sim is a simulator which was developed to simulate disasters and to develop strategies for dealing with emergencies (Appendix A). The author's contributions to I2Sim are: (a) the modeling and implementation of methods to represent complex cells with multi-input and multi-output (Appendix B); (b)integration of the cluster demon into one single machine; (c) development of a library of functions on GAM operations(Appendix C).

description: A quite unusual diffuse scattering phenomenology was observed in the single-crystal X-ray diffraction pattern of cubic perovskite BMT ($\mathrm{BaMg}_{1/3}\mathrm{Ta}_{2/3}\mathrm{O}_3$). The intensity of the scattering is parametrized as a set of cube-like objects located at the centers of reciprocal space unit cells, resembling very broad and cubic-shaped (1/2,1/2,1/2)-satellites. BMT belongs to perovskites of formula AB$'_{1/3}$B$"_{2/3}$O$_{3}$ (A=Mg, B$'=$Ta, B$"=$Mg). The cubes of the intensity can be attributed to the partial correlations of the occupancies of the B site. The pair correlation function is the Fourier transform of the diffuse scattering intensity and the latter's idealized form yields the unusual property of a power-law correlation decay with distance. Up to now this is observed only in a few exotic instances of magnetic order or nematic crystals. Therefore it cannot be classified as a short-range order phenomenon, as in most situations originating diffuse scattering. A Monte-Carlo search in configuration space yielded solutions that reproduce faithfully the observed diffuse scattering. Analysis of the results in terms of the electrostatic energy and the entropy point to this phase of BMT as a metastable state, kinetically locked, which could be the equilibrium state just below the melting point.

description: Several physically inspired problems have been proven undecidable; examples are the spectral gap problem and the membership problem for quantum correlations. Most of these results rely on reductions from a handful of undecidable problems, such as the halting problem, the tiling problem, the Post correspondence problem or the matrix mortality problem. All these problems have a common property: they have an NP-hard bounded version. This work establishes a relation between undecidable unbounded problems and their bounded NP-hard versions. Specifically, we show that NP-hardness of a bounded version follows easily from the reduction of the unbounded problems. This leads to new and simpler proofs of the NP-hardness of bounded version of the Post correspondence problem, the matrix mortality problem, the positivity of matrix product operators, the reachability problem, the tiling problem, and the ground state energy problem. This work sheds light on the intractability of problems in theoretical physics and on the computational consequences of bounding a parameter.

description: Here we use the Horizon-AGN simulation to test whether the spins of SMBHs in merger-free galaxies are higher. We select samples using an observationally motivated bulge-to-total mass ratio of < 0.1, along with two simulation motivated thresholds selecting galaxies which have not undergone a galaxy merger since z = 2, and those SMBHs with < 10% of their mass due to SMBH mergers. We find higher spins (> 5σ ) in all three samples compared to the rest of the population. In addition, we find that SMBHs with their growth dominated by BH mergers following galaxy mergers, are less likely to be aligned with their galaxy spin than those that have grown through accretion in the absence of galaxy mergers (3.4σ ). We discuss the implications this has for the impact of active galactic nuclei (AGN) feedback, finding that merger-free SMBHs spend on average 91% of their lifetimes since z = 2 in a radio mode of feedback (88% for merger-dominated galaxies). Given that previous observational and theoretical works have concluded that merger-free processes dominate SMBH-galaxy co-evolution, our results suggest that this co-evolution could be regulated by radio mode AGN feedback.

description: In this work we obtain the exact analytical scattering solutions of a particle (electron or hole) in a semiconductor double heterojunction - potential well / barrier - where the effective mass of the particle varies with position inside the heterojunctions. It is observed that the spatial dependence of mass within the well / barrier introduces a nonlinear component in the plane wave solutions of the continuum states. Additionally, the transmission coefficient is found to increase with increasing energy, finally approaching unity, whereas the reflection coefficient follows the reverse trend and goes to zero.
