description: The strongly coupled heterotic M-theory vacuum for both the observable and hidden sectors of the $B-L$ MSSM theory is reviewed, including a discussion of the "bundle" constraints that both the observable sector $SU(4)$ vector bundle and the a hidden sector bundle induced from a line bundle must satisfy. Gaugino condensation is then introduced within this context, and the hidden sector bundles that exhibit gaugino condensation are presented. The condensation scale is computed, singling out one line bundle whose associated condensation scale is low enough to be compatible with the energy scales available at the LHC. The corresponding region of Kähler moduli space where all bundle constraints are satisfied is presented. The generic form of the moduli dependent $F$-terms due to a gaugino superpotential - which spontaneously break $N=1$ supersymmetry in this sector - is presented and then given explicitly for the unique line bundle associated with the low condensation scale. The moduli dependent coefficients for each of the gaugino and scalar field soft supersymmetry breaking terms are computed leading to a low-energy effective Lagrangian for the observable sector matter fields. We then show that at a large number of points in Kähler moduli space that satisfy all "bundle" constraints, these coefficients are initial conditions for the renormalization group equations which, at low energy, lead to completely realistic physics satisfying all phenomenological constraints. Finally, we show that a substantial number of these initial points also satisfy a final constraint arising from the quadratic Higgs-Higgs conjugate soft supersymmetry breaking term.

description: We study strongly-coupled, approximately scale-invariant gauge theories, which develop a mass gap in the infrared. We argue that a large number of fermion flavours is most suitable to provide an ultraviolet completion for the composite Higgs scenario. The holographic approach allows to describe the qualitative features of the non-perturbative dynamics in the Veneziano limit. We introduce new bottom-up holographic models, which incorporate the backreaction of flavour on the geometry, and show that this can correlate the mass gap to the scale of flavour-symmetry breaking. We compute the mass spectrum for the various composite bosonic states, and study its dependence on the scaling dimension of the symmetry-breaking operators, as well as on the number of flavours. The different regions with a light dilaton are critically surveyed. We carefully assess the domain of validity of the holographic approach, and compare it with lattice simulations and the Nambu--Jona-Lasinio model.

The Socioeconomic Impact of the Mountain Parkway and KY 15

Subjects: subject: Transportation Engineering

description: A study of socioeconomic variables in a nine-county region in Eastern Kentucky was undertaken to determine whether significant growth had occurred since the opening of the Mountain Parkway and reconstruction of KY 15. It was hypothesized that these roads have acted as catalysts with available resources to promote a better quality of life.  Study revealed that, while income levels and business sales have enjoyed substantial increases, overall quality of life is still poor. Educational facilities are inadequate; economic diversification in business types is limited; coal is still the main stimulant for income and employment. However, outmigration of persons from the area has been reversed simply because economic conditions are better due to the reemergence of coal.  Since the return of coal as a more important energy resource for the nation has only occurred recently, the full impact of the energy crisis and better highways has yet to be seen in regard to socio-economic stimulation of this traditionally depressed region.

description: Flag verification techniques are useful in quantum error correction for detecting critical faults. Here we present an application of flag verification techniques to improving post-selected performance of near-term algorithms. We extend the definition of what constitutes a flag by creating error-detection gadgets based on known transformations of unitary operators. In the case of Clifford or near-Clifford circuits, these unitary operators can be chosen to be controlled Pauli gates, leading to gadgets which require only a small number of additional Clifford gates. We show that such flags can improve circuit fidelities by up to a factor of 2 after post selection, and demonstrate their effectiveness over error models featuring single-qubit depolarizing noise, crosstalk, and two-qubit coherent overrotation.

A Dynamical Model for the Extra-planar Gas in Spiral Galaxies

Year: 2005

subject: FOS: Physical sciences

description: Recent HI observations reveal that the discs of spiral galaxies are surrounded by extended gaseous haloes. This extra-planar gas reaches large distances (several kpc) from the disc and shows peculiar kinematics (low rotation and inflow). We have modelled the extra-planar gas as a continuous flow of material from the disc of a spiral galaxy into its halo region. The output of our models are pseudo-data cubes that can be directly compared to the HI data. We have applied these models to two spiral galaxies (NGC891 and NGC2403) known to have a substantial amount of extra-planar gas. Our models are able to reproduce accurately the vertical distribution of extra-planar gas for an energy input corresponding to a small fraction (<4%) of the energy released by supernovae. However they fail in two important aspects: 1) they do not reproduce the right gradient in rotation velocity; 2) they predict a general outflow of the extra-planar gas, contrary to what is observed. We show that neither of these difficulties can be removed if clouds are ionized and invisible at 21cm as they leave the disc but become visible at some point on their orbits. We speculate that these failures indicate the need for accreted material from the IGM that could provide the low angular momentum and inflow required.

Subjects: subject: Transportation Engineering

description: Controlled-gradient (CG), constant-rate-of-strain (CRS), and conventional incremental-loading (STD) consolidation testing are compared and evaluated. Undisturbed samples representing three soils common to Kentucky were used in the testing program. Settlements estimated by each testing technique were compared with settlement records from one of the sites. Results of 15 CG, 14 CRS, and 32 STD consolidation tests are shown. No significant differences were noted in values obtained from the three types of consolidation tests. Feasibility of the new test methods for routine testing is briefly discussed and recommendations were made for refinements in testing procedures.

description: Charge quantization, or the absence thereof, is a central theme in quantum circuit theory, with dramatic consequences for the predicted circuit dynamics. Very recently, the question of whether or not charge should actually be described as quantized has enjoyed renewed widespread interest, with however seemingly contradictory propositions. Here, we intend to reconcile these different approaches, by arguing that ultimately, charge quantization is not an intrinsic system property, but instead depends on the spatial resolution of the charge detector. We show that the latter can be directly probed by unique geometric signatures in the correlations of the supercurrent. We illustrate these findings at the example Josephson junction arrays in the superinductor regime, where the transported charge appears to be continuous. Finally, we comment on potential consequences of charge quantization beyond superconducting circuits.

Effect of Pavement Texture on Traffic Noise

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1976
Subjects: subject: Transportation Engineering

description: Noise from highway vehicles emanates primarily from engine exhausts, tire-pavement interaction) gears, and rattles. Studies have shown that at high speeds tires become the dominant generators of noise. Measurements on different road surfaces have produced different noise-versus-speed relationships (1). This led to the road surface adjustment used in the noise prediction procedure developed in NCHRP Report 117 (2). This adjustment called for a 5 dBA reduction for smooth surfaces (very smooth, seal-coated asphalt pavement) and a 5 dBA increase for rough surfaces (rough asphalt pavement with voids 1/2 inch (12 mm) or larger in diameter and grooved concrete). There was no adjustment for normal surfaces (moderately rough asphalt and concrete pavements).  The surface descriptions are vague, and it is left to the discretion of the user to apply adjustments where applicable. Consideration was given initially in this report to ''rough" surfaces, but the term was abandoned because it seemed vague and maybe misleading. Also, various degrees of roughness gave a wide range of noise levels. In fact, it appears that the terms "smooth", "normal", and "rough" address only that portion of tire noise generated by drumming or percussion of the tire against knobs in the pavement surface. "Smooth" does not distinguish "smooth and dense" from "smooth and porous". It has been argued that the -5 dBA adjustment should not be used since some truck tires become excessively noisy on very smooth surfaces and inasmuch as such surfaces are presumed to be ready for renewal because of their inherent low friction characteristics (3). Minimum noise is believed to be associated with smoothness and an optimum porosity. In this report, surfaces are identified according to Kentucky specifications.  Noise data were taken on all major types of surfaces presently used in Kentucky. A reference automobile was used to determine any difference in noise. Strip-chart records were made to evaluate the effect road surface type had on the noise of the entire traffic stream.

description: We present a detailed spectral analysis of Chandra/ACIS-S CC mode observations of the massive X-ray binary system SMC X-1. The system was observed during both the high and low X-ray states of the roughly 60-day superorbital period. The continuum spectra during both states are well represented by a power law with photon index $α$=0.9 and a blackbody of kT = 0.15keV. The high state spectra are dominated by the continuum and independent of orbital phase whereas the low state spectra show a strong orbital dependence as well as line emission from O, Ne, Mg, Fe, and Si. This is consistent with the states attributed to disk precession: during the high state X-ray emission is dominated by the compact source which is abrubtly eclipsed and during the low state the compact object is hidden by the disk and a larger, less luminous scattering region is responsible for the X-ray emission. A prominent Ne IX feature places a stringent limit (Log $ξ$ = 2.0-2.5) on the ionization parameter which constrains the wind dynamics of the system. The Fe line fluxes are related linearly to the blackbody fluxes indicating that both originate in the same region or are excited by the same mechanism. There is evidence for structure in the Fe-line that cannot be fully resolved by the current observations. The pulse period measured during our observations, 0.7057147$\pm$0.00000027s shows that the uninterrupted spin-up trend of SMC X-1 continues. We discuss the implications of our results for models of SMC X-1.

Transferable development rights : a policy analysis of a planning instrument and its application in Vancouver
Creators: name: Goelman, Ari
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis I examine the planning tool most commonly known as the transfer of development rights (TDR) and discuss its application in Vancouver. Before addressing Vancouver's use of TDR, I establish the context of TDR use in North America, suggest appropriate policy objectives and constraints for TDR programs, and outline a series of operational decisions made in designing any TDR program. I proceed to evaluate Vancouver's TDR program in light of these discussions. I found that TDR programs can be effective tools for redistributing the costs and benefits of certain types of land use restrictions. However, TDR programs vary widely in their effects. Depending on the specific design of a given program, it can have very different implications. In Vancouver, the TDR program is a relatively minor adjunct to the process of heritage preservation. Like any planning tool, Vancouver's TDR program strikes a balance between various objectives. However, it can be generally stated that fairness or distributional concerns are prevalent in Vancouver's program. Specifically, the protection of property rights is one of the defining elements of the program. Vancouver's program has been marked by a strong discretionary component, which has tended to create high transactions costs. In recent years, though, transaction costs in Vancouver have gone down significantly. As transaction costs have decreased and the program has grown more fluid, the take-up rate of transferable density in Vancouver has increased. These trends are widely expected to continue, as Vancouver's transfer of density program further matures.

description: We consider the communication of time-sensitive information in NextG spectrum sharing where a deep learning-based classifier is used to identify transmission attempts. While the transmitter seeks for opportunities to use the spectrum without causing interference to an incumbent user, an adversary uses another deep learning classifier to detect and jam the signals, subject to an average power budget. We consider timeliness objectives of NextG communications and study the Age of Information (AoI) under different scenarios of spectrum sharing and jamming, analyzing the effect of transmit control, transmit probability, and channel utilization subject to wireless channel and jamming effects. The resulting signal-to-noise-plus-interference (SINR) determines the success of spectrum sharing, but also affects the accuracy of the adversary's detection, making it more likely for the jammer to successfully identify and jam the communication. Our results illustrate the benefits of spectrum sharing for anti-jamming by exemplifying how a limited-power adversary is motivated to decrease its jamming power as the channel occupancy rises in NextG spectrum sharing with timeliness objectives.

description: By means of what competences educators can build up (and maintain) dissemination and awareness raising context to support care leavers ageing out of care? Notwithstanding the care leavers’ support is a central issue of family education, the training offered by academic and professional channels is still rather limited. Filling this gap and drawing on a recent national experience of training of trainers as transformative learning, this contribution analyzes educators’ competences required by the literature, comparing them with what emerged in the fieldwork. Particularly, the paper focuses on the competences of reading the context as a field, of recognizing their own theories and implicit premises and on the competence of building contexts of participation for care leavers and their families. In the discussion, these competences are analyzed by means of epistemological clues and are proposed as criteria for self-evaluation. In the Conclusions, several practical implications are proposed to build up and legitimize a community of practices that focuses on the capacity of educators to support different transitions, “germinating” reflections, tools, and innovative transformative solutions.

Within the cosmic screening approach, we develop the theory of scalar and vector perturbations. None of the energy density contrasts associated with the distinct components is treated as small. Consequently, the derived equations are valid at both sub- and super-horizon scales and enable simulations for a variety of cosmological models.

We suggest that a new round of fifth-force experiments is called for, in each of which three or more different pairs of samples are compared.

description: We study an interacting quantum dot in contact with a superconducting island described by the Richardson model with a Coulomb repulsion term controlling the number of electrons on the island. This Hamiltonian admits a compact matrix-product-operator representation and can be efficiently and accurately solved using the density-matrix renormalization group. We systematically explore the effects of the charging energy $E_c$. For $E_c$ comparable to the superconducting gap $Δ$, the subgap states are stabilized by the combination of Kondo exchange coupling and charge redistribution driven by the Coulomb interaction. The subgap states exist for both even and odd superconductor ground-state occupancy, but with very distinctive excitation spectra in each case. The spectral peaks are not symmetric with respect to the chemical potential and may undergo discontinuous changes as a function of gate voltages.

On the Economics of Drought Reserves

Subjects: Crop Production/Industries

description: In this article a new approach to one aspect of the economics of drought reserves will be discussed. In particular attention will be directed to the uncertainty of drought feed requirements. If future feed requirements were known with certainty then drought would lose many of its terrors, adequate reserves could be accumulated In time to meet a dry spell and unnecessary reserves could be dispensed with. The main worries associated with drought are the uncertainty as to when a drought will begin and how long it will last. Essentially in this article the aim will be to develop one new approach to the problems of risk and uncertainty raised by drought. The example used could have been more detailed and more realistic (for instance, the possibility of selling sheep, or buying grain and lucerne hay, rather than wheaten hay, could have been considered). Similarly, the problems of fodder deterioration and possible income tax effects have been ignored. This extra detail has not been included, because though it might have made the article more realistic for some readers, particular assumptions would have made it less realistic for others. In any case there would have been a tendency for the main principles of the argument to be lost in a mass of special assumptions.

description: A thickening at the outer edge of the accretion disk is usually invoked to explain the dips in the light curves of cataclysmic variables with stationary disks at phases ~0.7. The non-collisional interaction between the stream and the disk in the stationary solution raises the question of why matter appears at a considerable height above the accretion disk in such systems. Our three-dimensional numerical modeling demonstrates that a thickening of the halo above the disk can appear even in the absence of a direct collision between the stream and the disk. In the gas-dynamical flow pattern described with the "hot-line" model, a considerable fraction of the matter is accelerated in the vertical direction during the flow's interaction with the circumdisk halo. The vertical motion of the gas due to the presence of the z component of the velocity leads to a gradual thickening of the circumdisk halo. The computations reveal the strongest thickening of the halo above the outer edge of the disk at phases ~0.7, in agreement with observations for stationary-disk cataclysmic variables. This supports the hot-line model suggested earlier as a description of the pattern of the matter flows in semi-detached binaries, and presents new possibilities for interpreting the light curves of such systems.

Limits on mass outflow from optical tidal disruption events

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The discovery of optical/UV tidal disruption events (TDEs) was surprising. The expectation was that, upon returning to the pericenter, the stellar-debris stream will form a compact disk that will emit soft X-rays. Indeed the first TDEs were discovered in this energy band. A common explanation for the optical/UV events is that surrounding optically-thick matter reprocesses the disk's X-ray emission and emits it from a large photosphere. If accretion follows the super-Eddington mass infall rate it would inevitably result in an energetic outflow, providing naturally the reprocessing matter. We describe here a new method to estimate, using the observed luminosity and temperature, the mass and energy of outflows from optical transients. When applying this method to a sample of supernovae our estimates are consistent with a more detailed hydrodynamic modeling. For the current sample of a few dozen optical TDEs the observed luminosity and temperature imply outflows that are significantly more massive than typical stellar masses, posing a problem to this common reprocessing picture.

The effect of phytic acid removal on the acceptability of canola and rapeseed feedstuffs as partial and complete replacements for fish meal in salmonid diets
Creators: name: Prendergast, Angela Fay
Publisher: name: University of British Columbia
Year: 2009

description: Two experiments were conducted with juvenile rainbow trout (Oncorhynchus mykiss) (< 5g) in ambient well water, to investigate the influence of phytic acid removal on the feeding value of rapeseed and canola protein feedstuffs used as substitutes for fish meal and other animal protein in the diets. The first investigation examined whether phytic acid removal by commercial pretreatment of rapeseed protein concentrate (RPC) with microbial phytase, with /without essential amino acid supplementation or cation-anion balancing to mimic the chemical profile of a control diet based on fish meal (which provided 59% of the dietary protein), could improve the nutritional value of RPC for trout sufficiently to allow it to replace all of the fish meal without compromising performance. Results indicated that commercial dephytinization significantly enhanced the nutritional value of RPC to the extent that, with the addition of FINNSTIM™ (1.5 % DMB; palatability enhancer), it could replace all of the fish meal without compromising performance. Essential amino acid supplementation and cation-anion balancing provided no additional nutritional benefit. The second investigation, examined whether commercial dephytinization or dephytinization by oral administration of a low dose (1,000 PU/ g dry diet) or high dose (4,000 PU/g dry diet) of microbial phytase to diets in which fish meal provided 70% of the protein and canola meal (CM) provided 20%, or animal protein-free diets in which RPC provided 95% of the protein, could enhance the nutritional value of the diets for trout. Also, the effect of fibre reduction of CM with or without the addition of a high dose of phytase was examined. Findings indicated that in diets containing 1.5% FINNSTIM™ , commercial dephytinization as well as direct application of either dose of phytase significantly improved the nutritional value of CM for trout. By contrast, direct application of either dose of phytase did not improve the nutritional value of RPC for trout. Although commercial dephytinization did improve RPC nutritional value, the enhancement was not sufficient to make the diets nutritionally equal to the control fish meal diet. Fibre reduction with or without direct phytase addition did not nutritionally improve the CM diets to levels comparable to the control diets.

description: The essay aims to contribute to the reflection on the relational competences of educators and pedagogists engaged in the intervention of support to the parental competences in the negligent family contexts. In particular, we deepen the emotional-affective dynamics that affect parent-child relationship, in its problematic and suffering aspects, but also in the dimensions of recovery and promotion of a new family climate, inspired by trust, and generativity. In this direction, the task of the pedagogical operators consists in the reconstruction of a family story, which cannot be understood according to causal determinism, but which requires systemic attention to multiple conditions that can restore trust to the parental couple and hope, to the children victims of a negative heritage.

description: We study an attractive version of the East model using the real-space renormalization group (RG) introduced by Stella et al. The former is a kinetically constrained model with an Ising-like interaction between excitations, and shows striking agreement with the phenomonology of attractive colloidal systems. We find that the RG predicts two nonuniversal dynamic exponents, which suggests that in the out-of-equilibrium regime the model coarsens via a two-stage mechanism. We explain this mechanism physically, and verify this prediction numerically. In addition, we find that the characteristic relaxation time of the model is a non-monotonic function of attraction strength, again in agreement with numerical results.

description: This paper offers a frame to teaching reflexivity in Residential Child Care (RCC), a workplace featuring increasing yet recent professionalization, daily relationships and constant interaction with different agencies and professionals involved in the child protection system. Education in RCC takes place within an institutional, organizational and relational context with explicit and implicit presuppositions, dilemmas, and power dynamics. Thus, we identify systemic reflexivity as a required competence to cope with this complexity and act in a transformative way: an integrated, collective, and operational way of thinking, apt to support change and empower educators’ professional identity. The international literature review highlights the features of systemic reflexivity as a multi-layered process involving the individual professional, the working team, the dominant epistemology, and the power of good narratives. These are the ingredients of a training practice, here presented, designed to promote these competences in settings of both higher and workplace education.

description: The critical behavior of the Widom-Rowlinson mixture [J. Chem. Phys. 52, 1670 (1970)] is studied in d=3 dimensions by means of grand canonical Monte Carlo simulations. The finite size scaling approach of Kim, Fisher, and Luijten [Phys. Rev. Lett. 91, 065701 (2003)] is used to extract the order parameter and the coexistence diameter. It is demonstrated that the critical behavior of the diameter is dominated by a singular term proportional to t^(1-alpha), with t the relative distance from the critical point, and alpha the critical exponent of the specific heat. No sign of a term proportional to t^(2beta) could be detected, with beta the critical exponent of the order parameter, indicating that pressure-mixing in this model is small. The critical density is measured to be rho*sigma^3 = 0.7486 +/- 0.0002, with sigma the particle diameter. The critical exponents alpha and beta, as well as the correlation length exponent nu, are also measured and shown to comply with d=3 Ising criticality.

description: Looking at key theoretical and methodological aspects of the training targeting territorial service professionals involved in the “RdC03” research (Citizens’ income 0-3: interrelationships between income, parenting and development of children aged 0-3 years), the article focuses on a specific observation tool and the methodological and training proposal for its use. By contextualizing the educational observation and its three related dimensions (of everyday life, dialogical and relational), the paper opens up a reflection upon relational and communicative competences which, despite having their own specificity in the role embodied by educators, can become a shared operational tool that all educational, social and socio-health professionals employ in their practices with families and children towards social inclusion.

description: The contribution is focused on educational goals of L-19-Degree courses that the education professional must acquire in terms of relational and communicative knowledge and skills according to the learning outcomes. A second object is the historical pedagogical reconstruction on which the current conceptions of the educational relationship and the epistemological foundations of relational and communicative knowledge and skills are based on the training of trainers. The most significant moments of the pedagogical foundation of the student-educator relationship, and of a pedagogical reflection closely linked to philosophical reflexivity, are central elements of the core curriculum of L-19-Degree courses. In this regard, the fundamental theoretical issues are the studies that have highlighted the ideological character of education and the conformative nature of the student-educator relationship. The abovementioned studies, also read through the transformations of Pedagogy from unitary knowledge to plural knowledge, allow us to highlight, in a third moment, the tension towards the need for the relationship between the Pedagogical sciences and the other Sciences, even those with a character experimental empirical. The educational report is in fact one of the themes of knotting multiple researches on knowledge, not only of the humanities, but also and above all of the scientific ones. It is in this scenario that the contribution seeks to bring out the sense of the educational relationship in the direction of the formation of a subject who lives in an era characterized by the rarefaction of human relationships and the strong affirmation of technologies.

description: Educating means to accomplish a challenge that puts at the same time different degrees of complexity and difficulty. Evidently, the competences and professionalism of educators who operates in the contemporary socio-cultural complexity must have characteristics of a specialization to permit to put the emergency “in system” in any way, not being it an occasional event to manage but a condition of the work context. Starting from these premises, the paper aims to highlight the centrality that the educators’ professional training assumes in constructing transversal skills, in the proposal of a phenomenological perspective of education focused on the subjective value of experience and sense making.

Aspects of the dyonic Kerr-Sen-AdS$_4$ black hole and its ultraspinning version

description: We explore some (especially, thermodynamical) properties of the dyonic Kerr-Sen-AdS$_4$ black hole and its ultraspinning counterpart, and check whether or not both black holes satisfy the first law and Bekenstein-Smarr mass formulas. To this end, new Christodoulou-Ruffini-like squared-mass formulae for the usual dyonic Kerr-Sen-AdS$_4$ solution and its ultraspinning cousin are deduced. Similar to the ultraspinning Kerr-Sen-AdS$_4$ black hole case, we demonstrate that the ultraspinning dyonic Kerr-Sen-AdS$_4$ black hole does not always violate the reverse isoperimetric inequality (RII) since the value of the isoperimetric ratio can either be larger/smaller than, or equal to unity, depending upon the range of the solution parameters, as is the case only with an electric charge. This property is apparently distinct from that of the superentropic dyonic Kerr-Newman-AdS$_4$ black hole, which always strictly violates the RII, although both of them have some similar properties in other aspects, such as the horizon geometry and conformal boundary.

description: Starting from the reflection on the role of university education for professionals’ educational and training preparation, the paper proposes an exercise in re-reading the core competences, through the declination of the learning outcomes, coming out of the University study Course in Education and Training Science, L-19. In particular, relational-communicative competences are deepened, as the basis of the profession of educator and trainer, within the TECO-D/Pedagogy matrix, which represents a research tool on the core competencies of the L-19 itself. Relational-communicative competence is analyzed, deepened and defined using Dublin Descriptors, demonstrating the stringent link between training offer, skills and the construction of the professional family.

Galaxy Collisions - Dawn of a New Era

description: The study of colliding galaxies has progressed rapidly in the last few years, driven by observations with powerful new ground and space-based instruments. These instruments have used for detailed studies of specific nearby systems, statistical studies of large samples of relatively nearby systems, and increasingly large samples of high redshift systems. Following a brief summary of the historical context, this review attempts to integrate these studies to address the following key issues. What role do collisions play in galaxy evolution, and how can recently discovered processes like downsizing resolve some apparently contradictory results of high redshift studies? What is the role of environment in galaxy collisions? How is star formation and nuclear activity orchestrated by the large scale dynamics, before and during merger? Are novel modes of star formation involved? What are we to make of the association of ultraluminous X-ray sources with colliding galaxies? To what do degree do mergers and feedback trigger long-term secular effects? How far can we push the archaeology of individual systems to determine the nature of precursor systems and the precise effect of the interaction? Tentative answers to many of these questions have been suggested, and the prospects for answering most of them in the next few decades are good.
