Development of regeneration standards for sustainable forest management
Creators: name: Farnden, Craig
Publisher: name: University of British Columbia
Year: 2010

description: Linking regeneration activities to desired future forest conditions is a critical component of sustainable forest management. In much of North America, regeneration standards are an important administrative tool for ensuring this goal, but the links to predicted future outcomes are often weak. There is a need for developing regeneration standards that are solidly based on defensible predictions of future stand attributes and are indicators of a wide range of forest values. This dissertation describes the application of an analysis framework wherein many variations of simulated juvenile stand stem maps are used as the basis for regeneration standards development. The simulated stem maps were generated at the scale of operational cutting units using newly developed software routines. Spatial variation was emphasized at the scale of 5 to 200 m, reflecting underlying terrain and ecosystem patterns. The simulated stands were projected into the future using existing growth models, and sampled using simulated regeneration surveys. Simplified models to mimic predictions of selected stand attributes from the growth models were developed using survey summary data as predictor variables. The analysis system was applied to test relationships between various measures of stocking and yield for conifer monocultures. For the predictive relationships, curve shape and dispersion were found to be highly variable based on various stocking measurement parameters. Stocking was found to imperfectly account for spatial variation in the regenerating stand, and stocking thresholds for achieving a specific relative yield were found to vary by species and the top height at which relative yield was assessed. A second analysis developed simplified models to evaluate the contribution of regenerated stands to landscape level species composition in a vertically stratified, spruce-aspen (Picea glauca and Populus tremuloides) forest type. Various field assessment methods and model formulations were contrasted. Site index was found to have a major impact on absolute yield and on the curve shape for relationships between stocking and species composition. This dissertation provides a greater understanding of how to develop, interpret and apply regeneration standards. Relating standards and assessment methods to forest-level management goals provides a key link that is often missing in stand-level regeneration assessments.
The Nature of the Catholic High School Principalship in Alberta: Principals' Experiences and Perceptions

description: This qualitative study explored the question, “What does leadership look like in Alberta’s Catholic high schools”. Through survey, focus groups, and interviews with Catholic principals across the province, data was generated. The voices of Alberta’s Catholic high school principals emerged in significant ways. With 38% of the province’s principals responding to the initial survey, 23% of them participating in focus group discussions and 9% of them providing in depth insights through one on one interviews, a broad, varied, and comprehensive picture evolved. Through the use of grounded theory methodology, six complex themes emerged from the data: 1) Called: the vocation of the principal; 2) Entrusted: the responsibilities of the Catholic principal; 3) Gathered: the principal in community; 4) Liberated: freedom to “be” in a Catholic school culture; 5) Challenged: Leading 21st Century Catholic School; and 6) Appointed: Leadership in a Catholic school. An exploration of these themes in relation to the literature on leadership and Catholic schools resulted in a proposed framework for Catholic school leadership. Viewed through the lens of a Catholic paradigm, Catholic culture and community become the essential context for the discussion. Key leadership characteristics included a vocational call, intrinsic motivation, a compelling vision, an abiding love of others, a strong sense of hope, the leader as witness and servant, and the capacity to sacrifice. Catholic high school principals in Alberta told their stories with a language steeped in faith and a perspective that reflected their Catholic understanding of the world and their work. Catholic school leadership is spiritual leadership. This study provides synthesis and clarity regarding Catholic leadership in Alberta’s high schools. As well, a deeper understanding of the expectations for the province’s Catholic principals was realized. Principals’ opportunity for personal reflection enhanced their own understanding of their lived experience. By bringing the principals own voices to the table this study contributes to and enhances the literature on Catholic school leadership. Recommendations for Catholic principals, Catholic school boards, ACSTA and the provincial government conclude the study.

description: Hidden symmetries in a covariant Hamiltonian formulation are investigated involving gauge covariant equations of motion. The special role of the Stackel-Killing tensors is pointed out. A reduction procedure is used to reduce the original phase space to another one in which the symmetries are divided out. The reverse of the reduction procedure is done by stages performing the unfolding of the gauge transformation followed by the Eisenhart lift in connection with scalar potentials.

description: Stellar streams provide unique probes of galactic potentials, with the longer streams normally providing the cleaner measurements. In this paper, we show an example of a short tidal stream that is particularly sensitive to the shape of the Milky Way's dark matter halo: the globular cluster tidal stream NGC 5466. This stream has an interesting deviation from a smooth orbit at its western edge. We show that such a deviation favours an underlying oblate or triaxial halo (irrespective of plausible variations in the Milky Way disc properties and the specific halo parametrisation chosen); spherical or prolate halo shapes can be excluded at a high confidence level. Therefore, more extensive data sets along the NGC 5466 tidal stream promise strong constraints on the Milky Way halo shape.

description: The materiality of these works is not confined specifically to a digital, sculptural, two dimensional, or mechanical representation of an idea, instead the ideas are explored with materials that best suit the intention of the works. The thesis work, Hypotyposis, is a sculptural model of various fictional worlds that continually appear as a topic in science fiction films. These topics are often a metaphor for an idea or a thing that challenges humanity and changes how we view the world we live in. Hypotyposis is presented to the viewer as a realistic interpretation of a space and its intentions are to suspend the viewer’s disbelief, if only for a moment. The intention of this work is also to explore the relationship between the world as we experience it and the world found in fiction.

description: We consider the class of protocols that can be implemented by local quantum operations and classical communication (LOCC) between two parties. In particular, we focus on the task of discriminating a known set of quantum states by LOCC. Building on the work in the paper "Quantum nonlocality without entanglement" [BDF+99], we provide a framework for bounding the amount of nonlocality in a given set of bipartite quantum states in terms of a lower bound on the probability of error in any LOCC discrimination protocol. We apply our framework to an orthonormal product basis known as the domino states and obtain an alternative and simplified proof that quantifies its nonlocality. We generalize this result for similar bases in larger dimensions, as well as the "rotated" domino states, resolving a long-standing open question [BDF+99].

description: Two-neutron densities obtained from microscopic wave functions of $^6$He and $^8$He are investigated to reveal di-neutron correlations. In particular, the comparison of the two-neutron density with the product of one-neutron densities is useful for a quantitative discussion of di-neutron correlations. The calculations show that the S=0 spatial two-neutron correlation increases at the surface of $^6$He$(0^+_1)$ and $^8$He$(0^+_2)$. The enhancement is remarkable in the $^6$He$(0^+_1)$ ground state but not as prominent in the $^8$He$(0^+_1)$ ground state. Configuration mixing of many Slater determinants is essential to describe the di-neutron correlations. Two-neutron densities in $^{12}$C wave functions with $α$-cluster structures are also studied.

description: Two-dimensional porous carbon nanomaterials are proven to be promising hydrogen storage substrates as they possess high surface area, large number of active sites, low molecular mass, and hydrogen molecules can be adsorbed on both sides of these materials. By performing first-principles density functional theory-based calculations, we report ultrahigh reversible hydrogen uptake in lithium decorated 2D carbon allotrope PAI-graphene, which is formed of a regular pattern of polymerized as-indacenes (PAI). We found that a single unit cell of PAI-graphene can be decorated by 8 Li atoms, in which each Li atom can reversibly adsorb 4 hydrogen molecules, leading to 15.7 % of H uptake, remarkably higher than the DOE demand of 6.5 %. Li atom donates its valence 2s-electron to PAI-graphene and gets ionized. The adsorption energies of the various H2 attached to Li-atom are found to be suitable for reversible use during practical applications. Hydrogen molecules get attached to the ionized metal atom by electrostatic interactions. An energy barrier of 1.48 eV is present for the diffusion of Li atoms between the two most stable adsorption sites which justifies the absence of the clustering of Li atoms.

HOOP D6.5 Report on the education and awareness raising & acceptance activities
Creators: name: Gkiourkas, Theodoros
name: Spyridakos, Stavros
Publisher: name: Zenodo
Year: 2023

description: With the goals of promoting acceptance and usage of bio-based products and of creating awareness for biowaste recycling, the HOOP project developed and carried out various citizen engagement activities in the 8 HOOP Lighthouses. These can be clustered in citizen science interventions for optimizing the separate collection of OFMSW in the Lighthouse Cities and Regions and innovative pilot actions. The deliverable at hand reports specifically on the various pilot actions carried out in the Lighthouses under task 6.4.
These cities are embarking on a journey to optimize separate waste collection, foster behavior change, and cultivate acceptance of biowaste-derived products. At the core of this transformative effort lies a selection of pilot actions designed to bridge the gap between current practices and best methodologies.
These pilot actions consist of two distinct but synergistic streams: one focusing on education and awareness raising, and the other centering on the embrace of bio-based products. The former stream involves a range of creative approaches, such as specialized training programs to enhance waste recycling awareness, workshops empowering educators to integrate biowaste recycling into curricula, and the development of interactive online teaching materials and tools. Additionally, neighborhood competitions and reward mechanisms infuse an element of excitement into the process. Meanwhile, the latter stream encourages citizen interaction and acceptance of bio-based products through immersive community events, exhibitions, and public spaces. These platforms allow citizens to explore new products, seek clarifications, and engage in design-thinking workshops to co-create localized solutions, like personalized bio-based plastics.
To develop fitting pilot actions for each HOOP Lighthouse, CluBE (supported by CSCP and SfC) consulted all the Lighthouses on how to select the actions that best fit their needs. Additionally, CluBE offered bilateral meetings and consultations before and during the implementation process of these pilot actions. Each Lighthouse even the most upgraded in terms of Citizens Engagement Actions must focus at least on one of two different pillars. The first one is the separate collection, based on awareness raising and education activities through school visits, training the trainers sessions, and games for children and the second is the acceptance of bioproducts by feel and touch actions with the bioproducts and exhibitions of these products in the general public.
Various pilot actions were carried out successfully in the Lighthouses Albano Laziale, Western Macedonia, Bergen, Murcia, Münster, and Porto.
The Western Macedonia Region for example concentrated on school visits and bioproducts exhibitions as well as the promotion of recycling, upcycling, and waste reduction by promoting games constructed by wastes. The Greater Porto concentrated on the bioproducts exhibition to promote the acceptance of these products.

description: While the paths humans take play out in social as well as physical space, measures to describe and compare their trajectories are carried out in abstract, typically Euclidean, space. When these measures are applied to trajectories of actual individuals in an application area, alterations that are inconsequential in abstract space may suddenly become problematic once overlaid with geographic reality. In this work, we present a different view on trajectory similarity by introducing a measure that utilizes logical entailment. This is an inferential perspective that considers facts as triple statements deduced from the social and environmental context in which the travel takes place, and their practical implications. We suggest a formalization of entailment-based trajectory similarity, measured as the overlapping proportion of facts, which are spatial relation statements in our case study. With the proposed measure, we evaluate LSTM-TrajGAN, a privacy-preserving trajectory-generation model. The entailment-based model evaluation reveals potential consequences of disregarding the rich structure of geographic space (e.g., miscalculated insurance risk due to regional shifts in our toy example). Our work highlights the advantage of applying logical entailment to trajectory-similarity reasoning for location-privacy protection and beyond.

description: Secured Position Location and Tracking (PL&T) scheme is developed for multiple malicious radios or nodes detection using integrated key based strict friendly scheme and position location and tracking by multi-sectored based multiple target's PL&T. The friendly and malicious nodes detection is based on the integrated key consisting of symmetric keys, geographic location and round trip response time. Two strictly friend references dynamically form the tracking zone over the detected multiple malicious nodes using the multi-sectored adaptive beam forming. This PL&T technique is robust, precise, scalable, and faster than using the single reference, two reference and three reference nodes based PL&T method in the battlefield oriented Mobile Ad hoc Networks. The simulation results show that the lower relative speed bound of any participating node increased the switching overhead, the decreasing received energy with increasing number of the multi-sectored beams reduced tracking accuracy and the strict friendly authentication overhead depends upon the time period between two latest periodic authentication failures.

description: In this paper I examine my two years of research culminating towards my thesis exhibition. The paper shows the development of my work within the framework of the portrait. I discuss my artistic production with analysis of concept, process and my relationship with the history of portraiture. Central to my thesis exhibition installation is the concept of performance and engagement in an experience. My work examines the role of the viewer and the function of perception through the visual theme of the ‘performative’. My installation pieces are intended to describe the sincerity of my relationship with my model and mediums as well as alter the gallery space into a stage with which the viewer participates. This suggests an encouragement of the viewer to participate in an interpretation and reaction.

description: Abstract The dissertation is a contribution to the field of ethics in philosophy. In particular it is a contribution to the topic of relational ethics. It is an examination and evaluation of the philosophy of Emmanuel Levinas, the feminist ethics of care and the philosophy of Paul Ricoeur. All three examinations are concerned with the significance of relationships in ethical theorizing. This is a significant advancement in the field because it is based on ethics as concerned with the concrete lived reality of human existence, rather than on a detached theoretical approach to moral philosophy.

description: This study explores the perspectives of six young women on their experiences of growing up in government care and of multiple admissions to secure care. A mixed methods approach was utilized to gather information about adverse childhood events, and the participants lived experiences. The young women interviewed reported experiencing a high level of adverse events during their childhood. Their interviews highlighted several issues growing up in care such as placement instability, quitting school early, a loss of family relationships, substance abuse, and justice system involvement. This study suggests that the significant needs that youth in care may present with might not be sufficiently met by the system of care that limits their stay in secure care to 30 days. As adults, these young women presented with limited insight, and their stories suggest that they continue to struggle with untreated trauma, poverty and instability in their lives.
Control of cardiomyocyte lipoprotein lipase secretion following diabetes
Creators: name: Kim, Min Suk
Publisher: name: University of British Columbia
Year: 2010

description: During diabetes, when cardiac glucose utilization is impaired, the heart switches to exclusively using fatty acid (FA) for energy supply. This metabolic switching could lead to cardiomyocyte cell death, and eventually to heart disease. One mechanism for providing the heart with FA is lipoprotein lipase (LPL). LPL, synthesized in cardiomyocytes, is transferred to the vascular lumen where it catalyzes the breakdown of lipoprotein-triglyceride (TG) to provide FA to the heart. Following diabetes, heparin-releasable LPL activity at the coronary lumen increases by mechanisms that have yet to completely elucidated. Using diazoxide (DZ), an agent that decreases insulin secretion and causes hyperglycemia, we induced a substantial increase in LPL activity at the vascular lumen. In these hyperglycemic animals, we demonstrate that phosphorylation of AMPK, p38 MAPK, and heat shock protein (Hsp)25 produced actin cytoskeleton rearrangement. This structural rearrangement facilitated LPL translocation to the myocyte cell surface and eventually, the vascular lumen. Parallel to this mechanism, the robust phosphorylation of Hsp25 allowed PKCdelta to activate protein kinase D (PKD), an important kinase that regulates fission of vesicles from Golgi membranes. Rottlerin, a PKCdelta inhibitor, prevented PKD phosphorylation and the subsequent increase in coronary LPL. In myocytes in which PKD was silenced or a mutant form of PKCdelta was expressed, these cells were incapable of increasing LPL. Results from these studies could help in restricting cardiac LPL translocation, lowering FA delivery to the heart, and strategies to overcome contractile dysfunction following diabetes. We also evaluated the process which restricts LPL at the vascular lumen, especially during severe diabetes with its associated increase in hepatic lipoprotein TG secretion and adipose tissue lipolysis. Following severe hypoinsulinemia and hyperlipidemia induced by streptozotocin, we reported that activation of caspase-3, together with loss of 14-3-3zeta, restricted LPL translocation to the vascular lumen. When caspase-3 was inhibited, this compensatory response was lost, leading to profound lipid accumulation in the heart through promotion of LPL activity. Thus, although caspase-3 inhibition has been suggested to attenuate cardiac dysfunction, its inhibition following severe diabetes may induce cardiac damage through striking TG accumulation in the heart.

description: We numerically study the effects of varying electric conductivity and magnetic permeability of the bounding wall on a kinematic dynamo in a sphere for parameters relevant to Madison plasma dynamo experiment (MPDX). The dynamo is excited by a laminar, axisymmetric flow of von Karman type. The flow is obtained as a solution to the Navier-Stokes equation for an isothermal fluid with a velocity profile specified at the sphere's boundary. The properties of the wall are taken into account as thin-wall boundary conditions imposed on the magnetic field. It is found that an increase in the permeability of the wall reduces the critical magnetic Reynolds number Rm_cr. An increase in the conductivity of the wall leaves Rm_cr unaffected, but reduces the dynamo growth rate.

description: The objective of this thesis was to provide insight into the hydrogeology and biogeochemistry of the heavily biodegraded bitumen reservoirs of the Athabasca oil sands region of Alberta, Canada, using applications of aqueous and stable isotope geochemistry. Published data were used to generate a regional map of total dissolved solids concentrations in McMurray Formation waters. To explain the regional salinity data, a revised hydrogeological model was developed that incorporates localized upward flow of formation waters from saline Devonian aquifers into the bitumen-bearing McMurray Formation via karst-derived conduits. Where McMurray Formation waters are uninfluenced by connectivity with Devonian aquifers, topographic recharge from meteoric water is the dominant hydrogeological process. A new method was developed to determine the stable isotope composition and salinity of McMurray Formation waters from porewater samples extracted from drilling fluid-contaminated core. Mixing relationships of δ2H and δ18O values in drilling fluid and formation water were used to calculate the original formation water stable isotope composition and salinity from porewater extracted directly from oil sands drill core. Both vertical and lateral heterogeneity were observed on a reservoir-scale, and topographically-derived groundwater recharge was determined to be the dominant hydrogeological process in Suncor-Firebag lease area. Biogeochemical aspects of oil sands systems were investigated in two studies. The first study examined the impact of variable aqueous geochemistry on oil sands biogeochemistry, specifically methanogenesis and bacterial sulfate reduction, in laboratory-scale microcosms. Changes in aqueous geochemistry induced changes in the total amount of methane generated, and in the stable isotope ratios of carbon and hydrogen of generated methane. The second experiment measured natural abundance radiocarbon in dissolved inorganic carbon in a coal-bed methane reservoir in the Powder River Basin, Montana, USA. All samples of dissolved inorganic carbon and methane contained no detectable radiocarbon, and thus the carbon flux from biodegradation of coal was much greater than the carbon flux from recent groundwater recharge into the coal-bed aquifer system. Improved understanding of hydrogeological processes, and better understanding of reservoir biogeochemistry will lead to better decision making by industry and regulators during the development of oil sands resources, while our society transitions away from fossil energy over the coming century.

description: The study investigates the approach to collaboration in Humanities, within the Italian context, to test the possibility of collaborative digital library for scholars. The research hypothesis is that collaboration can foster innovation and scientific development: therefore, within Humanities, digital libraries can be the collaborative laboratory for research. Thus, understanding perception of scholars towards collaboration, especially online, and comprehending if wiki systems could be the framework of collaboration were the objectives of the study. A qualitative approach has been adopted, using case study as research method: ﬁve in-depth, semi-structured interviews to Digital Humanities scholars provide data integrated with interviews with two key informants (one of which is prof. Umberto Eco). The results of the study show that Humanities, within Italian context, do appreciate collaboration and the concept of a collaboratory digital library, though several issues need to be solved. In fact, Humanities are still tied with individual work and collaboration is not easy to pursue, for cultural, technical and political reasons. Great eﬀort needs to be done at many different levels to eliminate obstacles and facilitate online collaboration for scholars. The study provides a draft model for a collaborative digital library arisen from gathered data.

description: Quantum dots (QDs) are one of the promising candidates of interconnection between electromagnetic field and electrons in solid-state devices. Dark states appear as a result of coherence between the electromagnetic fields and the discrete energy levels of the system. Here, we theoretically solve the steady-state solutions of the density matrix equations for a thee-level double QD system and investigate the condition of the appearance of a dark state. We also numerically show the appearance of the dark state by time-dependent current characteristics.

description: While the dynamically rich behaviour of fully turbulent wakes is very high dimensional, the most energetic, large scale coherent structures generated through instability processes are typically low dimensional and are thereby conducive to reduced order modeling procedures. These large scale eddies associated with the flow instability have the most anisotropic and geometry dependent topology and act as a source of kinetic energy in the cascade process, making them the most important to characterize. Dissipative small scale structure can then be modelled with reasonable accuracy by traditional means. The present study experimentally educes the coherent structures in the complex three-dimensional wake of a wall-mounted finite square-cross-section cylinder of aspect ratio h/d=4 and 8 immersed in boundary layers of thickness delta/d=0.72 and 2.6 at a Reynolds number of 12,000. Coherent structure eduction is carried out using phase averaging and a novel generalized phase averaging technique that incorporates proper orthogonal decomposition (POD) modes that are most important in the nonlinear instability saturation process. Global flow estimation and mode construction is undertaken using linear pressure-POD coefficient correlations, applicable to experimental investigations where practicality demands that subdomains of the global field are measured asynchronously. The large-scale coherent structures of the wakes investigated are analyzed in terms of their topology, their turbulent kinetic energy (amounting to roughly half the total fluctuation energy), and their influence on turbulence production. The educed coherent vortical structures are found to have either full-loop or half-loop topological structure depending on the boundary layer thickness, showing vortical connector strands connecting alternately shed vortices from either side of the obstacle. The structure provides an explanation of the dipole and quadrupole distributions of streamwise vorticity that have previously been observed in these types of three-dimensional wakes. The reduced order nonlinear Galerkin models derived for the dynamics of the coherent structures using the generalized phase average are shown to successfully account for the slow base flow transients, the instability saturation mechanism, and the excitation of the second harmonic modes.

description: From our theoretical studies of resonant Raman transitions in two-electron quantum dots (artificial helium atoms) we show that in this system, the singlet-triplet Raman transitions are allowed (in polarized configuration) only in the presence of spin-orbit interactions. With an increase of the applied magnetic field this transition dominates over the singlet-singlet and triplet-triplet transitions. This intriguing effect can therefore be utilized to tune Raman transitions as well as the spin-orbit coupling in few-electron quantum dots.

description: Emerging vehicle automation and communication systems (VACS) may contribute to the improvement of vehicle travel time and the mitigation of motorway traffic congestion on the basis of appropriate control strategies. This work considers the possibility that automated, or semi-automated, vehicles are equipped with devices that perform (or recommend) lane-changing tasks. The lane-changing strategy MOBIL (minimizing overall braking induced by lane changing) has been chosen for its simplicity and ductility, as well as for the reduced number of parameters that need to be specified (namely, politeness factor and threshold). A wide set of simulations, where MOBIL has been implemented within the microscopic traffic simulator Aimsun for a calibrated motorway network (representing a stretch of motorway A12 in the Netherlands), has been performed. Simulations revealed the impact that the choice of different parameters have on the travel time of different vehicles, allowing also to analyse their behaviour with respect to different traffic conditions (without or with traffic congestion).

The First Billion Years project - III: The impact of stellar radiation on the coevolution of Populations II and III

description: With the first metal enrichment by Population (Pop) III supernovae (SNe), the formation of the first metal-enriched, Pop II stars becomes possible. In turn, Pop III star formation and early metal enrichment are slowed by the high energy radiation emitted by Pop II stars. Thus, through the SNe and radiation they produce, Populations II and III coevolve in the early Universe, one regulated by the other. We present large (4 Mpc)^3, high resolution cosmological simulations in which we self-consistently model early metal enrichment and the stellar radiation responsible for the destruction of the coolants (H2 and HD) required for Pop III star formation. We find that the molecule-dissociating stellar radiation produced both locally and over cosmological distances reduces the Pop III star formation rate at z > 10 by up to an order of magnitude compared to the case in which this radiation is not included. However, we find that the effect of LW feedback is to enhance the amount of Pop II star formation. We attribute this to the reduced rate at which gas is blown out of dark matter haloes by SNe in the simulation with LW feedback, which results in larger reservoirs for metal-enriched star formation. Even accounting for metal enrichment, molecule-dissociating radiation and the strong suppression of low-mass galaxy formation due to reionization at z < 10, we find that Pop III stars are still formed at a rate of ~ 10^-5 M_sun yr^-1 Mpc^-3 down to z ~ 6. This suggests that the majority of primordial pair-instability SNe that may be uncovered in future surveys will be found at z < 10. We also find that the molecule-dissociating radiation emitted from Pop II stars may destroy H2 molecules at a high enough rate to suppress gas cooling and allow for the formation of supermassive primordial stars which collapse to form ~ 100,000 solar mass black holes.

description: In this work, we have studied the thermodynamic quantities like temperature of the universe, heat capacity and squared speed of sound in generalized gravity theories like Brans-Dicke, Ho$\check{\text r}$ava-Lifshitz and $f(R)$ gravities. We have considered the universe filled with dark matter and dark energy. Also we have considered the equation of state parameters for open, closed and flat models. We have observed that in all cases the equation of state behaves like quintessence. The temperature and heat capacity of the universe are found to decrease with the expansion of the universe in all cases. In Brans-Dicke and $f(R)$ gravity theories the squared speed of sound is found to exhibit increasing behavior for open, closed and flat models and in Ho$\check{\text r}$ava-Lifshitz gravity theory it is found to exhibit decreasing behavior for open and closed models with the evolution of the universe. However, for flat universe, the squared speed of sound remains constant in Ho$\check{\text r}$ava-Lifshitz gravity.

description: We propose a boundary action to complement the recently developed duality manifest actions in string and M-theory using generalized geometry. This boundary action combines the Gibbons-Hawking term with boundary pieces that were previously neglected in the construction of these actions. The combination may be written in terms of the metric of generalized geometry. The result is to produce an action that is duality invariant including boundary terms.
