description: Metal-organic macrocycles have received increasing attention not only due to their versatile applications such as molecular recognition, compounds encapsulation, anti-bacteria and others, but also for their important role in the study of structure-property relationship at nano scale. However, most of the constructions utilize benzene ring as the backbone, which restricts the ligand arm angle in the range of 60, 120 and 180 degrees. Thus, the topologies of most metallo-macrocycles are limited as triangles and hexagons, and explorations of using other backbones with large angles and the construction of metallo-macrocycles with more than six edges are very rare.

In this study, we present a novel strategy for self-assembly two giant heptagonal metallo-macrocycles with an inner diameter of 5 nm, by embedding metal nodes into the ligand backbone and regulating the ligand arm angle. By complexing with metal ions, the angle between two arms at the 4,4” position of the central terpyridine (tpy) was extended, resulting in ring expansion of the metallo-macrocycle. This approach enabled the construction of giant and more complex metallo- macrocycles that could not be achieved with traditional benzene ring backbones. The characterization of complex molecules often requires the use of multiple techniques, such as multi-dimensional and multinuclear NMR and multidimensional mass spectrometry analysis. Here, we also utilized transmission electron microscopy (TEM) and ultra-high vacuum (∼E-10 torr) low-temperature (∼77 K) scanning tunneling microscopy (UHV-LT-STM) to characterize complex supramolecules. The resulting metallo-macrocycles formed hierarchical self-assembled nanotube structures at larger densities, which is observed by TEM, while UHV-LT-STM was used for direct visualization of individual complex supramolecules deposited on an Au(111) substrate. Our findings indicate that UHV-LT-STM is an effective methodology for characterizing supramolecules at a single molecule level, providing more details of the molecular structure that is difficult to resolve by the resolution of TEM.
title: The otic region of the skull of neognathous birds: on the homology and comparative morphology of some neurovascular and muscular foramina and other external skeletal structures
Creators: name: Mayr, Gerald
Publisher: name: Senckenberg Gesellschaft für Naturforschung
Year: 2019

description: Even though detailed anatomical studies of the otic region exist for some avian species, there are few comparative data for most extant higher-level clades. In the present study, the external osteology of the otic region of birds is studied in a broad taxonomic context and a focus has been put on the homology of neurovascular and muscular foramina in taxa of the Neognathae. It is detailed that this part of the skull offers significant structural variation, which is of potential phylogenetic and physiological significance. The otic region of many taxa is for the first time illustrated and some osteological features are highlighted that are not or only rarely commented on in existing accounts of the otic region. These include the foramina and osseous guiding structures for the occipital ramus of arteria ophthalmica externa, as well as the skeletal correlates of ramus palatinus and ramus hyomandibularis of nervus facialis, and the foramen for musculus columellae. In addition, different conformations of the pila otica are described and some structures of unknown significance are highlighted, which require further research.
Eco-cultural Management Implications of California Hazelnut Treatment with Wild and Prescribed Fire: A Case Study in Northern California

description: The tribal nations of northwest California are restoring their practice of cultural prescribed burning to facilitate the regeneration of basket-making materials, medicines, and food. Among the cultural foods are California hazelnut nuts (corylus cornuta var. californica). California hazelnut nut production was hypothesized to improve through the application of fire at certain points in the development of hazelnut stands and the biological communities surrounding them. In order to investigate the effect of fire on California hazelnut nut productivity, multiple 100 m2 sampling plots were created within areas where wildfires or prescribed burns had occurred, and areas where they have not occurred in >13 years. In those plots, precipitation, nuts per shrub, solar access of individual shrubs, stem diameter, number of stems, among other relevant factors in nut production were measured.  Time since last fire (TSLF) was later calculated based upon CalFire fire perimeter maps. Monitoring areas were identified through the local knowledge of Tribal and United States Forest Service staff. Generalized linear mixed models (GLMMs) indicate that the number of nuts produced by individual hazelnuts varied based on interactions between solar access and TSLF. Based on the results of this study, there are multiple ways to manage hazelnut shrubs in order to optimize nut production for cultural food usage. Future studies need to focus on the correlation between fire regime factors and the prevalence of other cultural resources in order to determine the most economically efficient way of applying fire to tribal and public lands.
Search for the standard model Higgs boson in $\bm{\ellν}$+jets final states in 9.7~fb$\bm{^{-1}}$ of $\bm{p\bar{p}}$ collisions with the D0 detector

description: We present, in detail, a search for the standard model Higgs boson, $H$, in final states with a charged lepton (electron or muon), missing energy, and two or more jets in data corresponding to 9.7 fb$^{-1}$ of integrated luminosity collected at a center of mass energy of $\sqrt{s}$ = 1.96 TeV with the D0 detector at the Fermilab Tevatron $p\bar{p}$ Collider. The search uses $b$-jet identification to categorize events for improved signal versus background separation and is sensitive to associated production of the $H$ with a $W$ boson, $WH\to\ellνb\bar{b}$; gluon fusion with the Higgs decaying to $W$ boson pairs, $H\to WW\to\ellνjj$; and associated production with a vector boson where the Higgs decays to $W$ boson pairs, $VH\to VWW \to \ellνjjjj$ production (where $V = W$ or $Z$). We observe good agreement between data and expected background. We test our method by measuring $WZ$ and $ZZ$ production with $Z\to b\bar{b}$ and find production rates consistent with the standard model prediction. For a Higgs boson mass of 125 GeV, we set a 95%\ C.L. upper limit on the production of a standard model Higgs boson of \obslimA$\timesσ_{\rm SM}$, where $σ_{\rm SM}$ is the standard model Higgs boson production cross section, while the expected limit is \explimA$\timesσ_{\rm SM}$. We also interpret the data considering models with fourth generation fermions, or a fermiophobic Higgs boson.

Learning Object-Centric Visual Representations for Common Sense Reasoning

Subjects: Machine learning

description: People understand the world as a sum of its parts. Our effortless mental ability to simulate and imagine what will happen crucially depends on a scene representation that is compositional with respect to objects and the interactions between them. Similarly, learning representations with an emphasis on the perception and understanding of objects plays a key role in building human-like AI capable of supporting higher-level cognitive abilities such as common sense reasoning, causal reasoning, and goal-oriented planning. Many current methods in machine learning focus on learning structured representations in which objects are only implicitly represented, which poses a threat to model interpretability. Motivated by these observations, this work aims to develop algorithms for learning object-centric representations in which objects are explicitly represented. Given the importance of objects in human cognition, we draw inspiration from cognitive science to motivate and provide theoretical underpinnings. Specifically, we take a rationalist approach in augmenting deep neural network architectures to exhibit object-centric representations, and demonstrate empirically how these representations can be efficieintly leveraged for downstream tasks such as controllable image synthesis.

description: In a critical content analysis of 27 Caldecott Medal books from two decades, I examine the ways in which American children’s literature reflects and promotes norms established during socialization and how these representations have changed over time. I analyze the relationship between the cultural and symbolic capital possessed by characters; I implement the terms racial diversity, shallow diversity (i.e., inclusion of nondominant cultural capital), and deep diversity (i.e., inclusion of nondominant cultural capital with prestige or authority) to establish a more nuanced understanding of diversity. I found that racial diversity in Caldecott literature has increased over time, yet not for books recognized as the overall winner of their year. My sample indicates most books displaying shallow diversity also display deep diversity; however, for books without deep diversity, more work is needed by leaders in the field to ensure that children’s literature during this critical period of socialization promotes inclusive norms.

description: Natural kamacite samples (Fe92.5Ni7.5) from a fragment of the Gibeon meteorite were studied as a proxy for terrestrial core material to examine phase transition kinetics under shock compression for a range of different pressures up to 140 GPa. In situ time- resolved x-ray diffraction (XRD) data were collected from a body-centered cubic (bcc) kamacite section that transforms to the high-pressure hexagonal close-packed (hcp) phase with sub-nanosecond temporal resolution. The starting coarse-grained kamacite crystals rapidly transformed to highly oriented crystallites of the hcp phase at maximum compression. The hcp phase persisted for as long as 9.5 ns following shock release. Comparing the c/a ratio with previous static and dynamic work on Fe and Fe-rich Fe-Ni alloys, it was found that some shots exhibit a larger than ideal c/a ratio, up to nearly 1.65. This work represents the first time-resolved laser shock compression structural study of a natural iron meteorite, relevant for understanding the dynamic material properties in metallic planetary bodies during impact events and the evolution of the elastic behavior of the Earth’s core.

description: We present the discovery of eight new radio pulsars located in the Large Magellanic Cloud (LMC). Five of these pulsars were found from reprocessing the Parkes Multibeam Survey of the Magellanic Clouds, while the remaining three were from an ongoing new survey at Parkes with a high resolution data acquisition system. It is possible that these pulsars were missed in the earlier processing due to radio frequency interference, visual judgment, or the large number of candidates that must be analysed. One of these new pulsars has a dispersion measure of 273 pc cm$^{-3}$, almost twice the highest previously known value, making it possibly the most distant LMC pulsar. In addition, we present the null result of a radio pulse search of an X-ray point source located in SNR J0047.2$-$7308 in the Small Magellanic Cloud (SMC). Although no millisecond pulsars have been found, these discoveries have increased the known rotation powered pulsar population in the LMC by more than 50%. Using the current sample of LMC pulsars, we used a Bayesian analysis to constrain the number of potentially observable pulsars in the LMC to within a 95% credible interval of 57000$^{+70000}_{-30000}$. The new survey at Parkes is $\sim$20% complete and it is expected to yield at most six millisecond pulsars in the LMC and SMC. Although it is very sensitive to short period pulsars, this new survey provides only a marginal increase in sensitivity to long periods. The limiting luminosity for this survey is 125 mJy kpc$^2$ for the LMC which covers the upper 10% of all known radio pulsars. The luminosity function for normal pulsars in the LMC is consistent with their counterparts in the Galactic disk. The maximum 1400 MHz radio luminosity for LMC pulsars is $\sim 1000$ mJy kpc$^2$.

Rather than a uniform approach to Putin, Alexander-Greene finds significant variation not only in how Putin is represented but also the works' origins, perspectives, and literary approaches. Together, they underscore the paradox between the fantasy of control, tied to the figure of the Russian leader, and the more chaotic reality. (Master's thesis)

description: Since the People’s Republic of China opened for international adoption in the early 1990s, a great deal of scholarship has been produced regarding the One-Child Policy and overseas Chinese adoptees. Rather than looking at the contemporary world, this project is concerned with the topics of adoption and child abandonment in premodern Chinese culture and society. It asks: what did it mean to be an adoptee or “rejected” child in “traditional” China? To understand the realities of these two distinct (though at times overlapping) groups, I examine how obtaining and dismissing descendants functioned as a custom intended to protect the family as a unit. Further, the conceptual, ethical, gendered, and symbolic dimensions of these practices are explored: male adoptees occupied an ambiguous and tenuous position in their families, society, and Confucian orthodoxy, while stories of abandoned children were utilized as cultural tropes and for moral instruction. This sociocultural and historical study is also accompanied by an analysis of the development of welfare institutions and programs for needy populations during Ming-Qing China. Created in response to heightened attention on infanticide (particularly female infanticide) as well as specific crises, child relief efforts changed adoption procedures, gave rise to novel "adoptive" relationships, and presented opportunities for domestic and foreign benefactors to impose their own values onto family-less Chinese children.

description: We study the competition between domain coarsening in a symmetric binary mixtures below the critical temperature and turbulent fluctuations. We find that the coarsening process is arrested in presence of turbulence. The physics of the process shares remarkable similarities with the behaviour of diluted turbulent emulsions and the arrest length scale can be estimated with an argument similar to the one proposed by Kolmogorov and Hinze for the maximal stability diameter of droplets in turbulence. Although in the absence of flow the microscopic diffusion constant is negative, turbulence does effectively arrest the inverse cascade of concentration fluctuations by making the low wavelength diffusion constant positive for scales above the Hinze length.
title: A variational approach to brittle fracture and cohesive delamination:modelling and technological applications
Creators: name: Carollo, Valerio
Publisher: name: IMT Alti Studi Lucca
Year: 2018

description: A new computational model is used for the study of fracture phenomena in homogeneous and composite materials. The computational model is based on the coupling between the phase field model and the cohesive zone model within the framework of the finite element method. This model is adopted from literature and consistently extended. The enhancements enclose the combination of the model with plasticity and its extension to the 3D finite elasticity framework. This extension is formulated in a consistent way by means of the variational approach. The model is validated through numerical examples mostly based on experimental results. The experiments are designed and performed by means of experimental facilities suitable for micro testing. The numerical simulations comprehend problems at different scales of homogeneous and composite materials in the bi-dimensional and three-dimensional space. The model results particularly appropriate for many technological applications. Among the different applications, the following cases are analysed: the competition between crack propagation and plasticity; the adhesive wear phenomenon considering the fracture of the micro asperities of two surfaces in contact; the mechanical behaviour of a nanolaminate and a microlaminate; the interaction between crack propagation and delamination. In the latter application is where the model shows its strength. The competition between crack propagation and delamination in composite materials is simulated without the necessity of remeshing or crack tracking algorithms. The model is particularly suitable for the exploitation in many engineering industrial fields.
title: Equivalences in differential and algebraic systems: theoretical and practical aspects
Creators: name: Tognazzi, Stefano
Publisher: name: IMT Alti Studi Lucca
Year: 2019

description: Systems of ordinary differential equations (ODEs) are a widespread model to describe a variety of dynamical systems. When the size of these systems becomes large to find a numerical solution, model reduction is needed. Although many state aggregation notions have been developed in the literature in this dissertation we focus on backward differential equivalence (BDE) that identifies variables of ODE systems that have identical solutions whenever starting from the same initial conditions. This notion has been used effectively as a technique of reduction for chemical reaction networks. In this dissertation we aim at extending the capabilities of backward differential equivalence. We explore the following directions of research: first, we investigate the relationship between BDE and the notions of centrality on networks. Centrality measures address the task of assigning a measure of importance to each node in a network, a possible example being PageRank. Then, we study differential algebraic equations (DAEs), a widespread dynamical model that describes continuosly evolving quantities defined with differential equations, subject to constraints expressed through algebraic relationships. We investigate how we can extend the line of research on backward differential equivalence on ODEs to a notion of equivalence that relates DAEs variables that have equal solutions at all time points. Ultimately, we extend the practical capabilities of BDE on CRNs. Discovering relations between CRNs is a relevant problem in computational system biology. In this dissertation we investigate how we can combine BDE with an heuristic technique to construct a state-of-the-art algorithm to find relationships between CRNs.

description: A systematic coarse graining of microscopic atomic displacements generates a local elastic deformation tensor ${\mathsf D}$ as well as a positive definite scalar $χ$ measuring non-affinity, i.e. the extent to which the displacements are not representable as affine deformations of a reference crystal. We perform an exact calculation of the statistics of $χ$ and ${\mathsf D}$ and their spatial correlations for solids at low temperatures, within a harmonic approximation and in one and two dimensions. We obtain the joint distribution $P(χ, {\mathsf D})$ and the two point spatial correlation functions for $χ$ and ${\mathsf D}$. We show that non-affine and affine deformations are coupled even in a harmonic solid, with a strength that depends on the size of the coarse graining volume $Ω$ and dimensionality. As a corollary to our work, we identify the field, $h_χ$, conjugate to $χ$ and show that this field may be tuned to produce a transition to a state where the ensemble average, $$, and the correlation length of $χ$ diverge. Our work should be useful as a template for understanding non-affine displacements in realistic systems with or without disorder and as a means for developing computational tools for studying the effects of non-affine displacements in melting, plastic flow and the glass transition.

description: This paper examines the evolution of the public and private sphere in North Korea before and after the paradigmatic social change caused by the famine of 1994-1998, also known as the Arduous March.  Of particular interest is how depiction of the public and private spheres in state-produced films has adapted to respond to this social shift.  Analysis draws upon six post-famine films with female leads: “A Mother’s Happiness” (2003),  “A Schoolgirl’s Diary” (2006), “Kites Flying in the Sky” (2008), “A Flower in the Snow” (2011), “Comrade Kim Goes Flying” (2012), and “ The Story of Our Home” (2016).  Compared with prior films, depictions of the public and private sphere appear to be intentionally blurred through two common narrative devices: the reframing of private aspirations as public affairs and the portrayal of motherhood and reproductive labor as service to the state.  Two of the six films include the famine in their narratives, offering a revisionist interpretation of the famine that implies the markets were not necessary for survival.  Taken together, these six films represent a propaganda campaign targeting the agents of the private sphere - North Korea’s housewives - with the end goal of convincing women to forego private market activity and dedicate their labor to serving the needs of the state.

Pyongyang in Ink and Concrete: North Korean Urban Modernism in Kim Il Sung Period Fiction, 1967-1994

description: This research fills a lacuna in the research on North Korean official culture by elucidating North Korean urban modernism of the Kim Il Sung period (1967-1994), a period which has been framed in extant research as a move away from, rather than toward modernity. I explore the urban modernism of capital construction fiction, that is, North Korean fiction which portrays the construction of the North Korean capital Pyongyang from the perspectives of manual labourers, architects, urban planners, managers, party functionaries and the Leader (Kim Il Sung/Kim Jong Il). Capital construction fiction first emerged as a genre during this period and is intimately connected with both the personality cult of the Leaders, and a unique vision of urban modernism. This research explores Ch’oe Haksu’s Pyongyang Time (1976), the seminal work of capital construction fiction and one of the most important novels in the canon of Juche literature, and two other examples of capital construction fiction. I analyze the way in which this body of literature presents its own version of the city strolling flâneur, how it prizes urban planning, and how it frames its own picture of urban modernism in contradistinction to the capitalist city. The picture of North Korean urbanism that emerges is one that is decisively modernist: North Korean flânerie is in evidence and calls on characters to participate in construction. Urban planning allows for the compression of time, enabling Pyongyang to speed its way into new stages of teleological development as part of an ever-accruing schema of progress. Marked differences to capitalist urban modernism result from it being a form of Asian, anti-Western alternative modernity in its self-conception, with grounding in “ethnic form”—but this is not traditionalism. If modernism is defined according to belief in progress, North Korean urban modernism may even be hypermodernist.

description: Associated production of the Higgs boson with a top-antitop pair is a key channel to gather further information on the nature of the newly discovered boson at the LHC. Experimentally, however, its observation is very challenging due to the combination of small rates, difficult multi-jet final states and overwhelming backgrounds. In the Standard Model the largest number of events is expected when h->bb, giving rise to a WWbbbb signature, deluged in tt+jets. A promising strategy to improve the sensitivity is to maximally exploit the theoretical information on the signal and background processes by means of the matrix element method. We show how, despite the complexity of the final state, the method can be efficiently applied to discriminate the signal against combinatorial and tt+jets backgrounds. Remarkably, we find that a moderate integrated luminosity in the next LHC run will be enough to make the signature involving both W's decaying leptonically as sensitive as the single-lepton one.

description: How flexible are children’s semantic representations? It is unknown whether they understand
that others may have semantic boundaries that are different from their own. Adults update their
expectations about how a speaker uses quantifiers after exposure to the speaker (Yildirim,
Degen, Tanenhaus, & Jaeger, 2016). Here, we explore whether this ability is present in
preschool-aged children. In Experiment 1, we show that preschoolers have adult-like
expectations about how a generic speaker would use the quantifiers some and many. They prefer
some for proportions less than 50% and many for proportions above 50%. In Experiment 2, forty
4 and 5-year-olds (mean = 4.6) were exposed to a speaker who was biased to either prefer using
some or many in a situation when describing a proportion of 50%. After exposure, participants
updated their expectations about the use of some and many, such that they aligned better with the
exposure speaker’s usage, suggesting that preschoolers are able to engage in semantic adaptation.
Experiment 3 replicates the results of Experiment 2 with sixty participants (mean = 4.8) while
reducing potential confounds. Experiment 4 investigates whether preschoolers can adapt to two
different speakers, one who is biased to use some and one who is biased to use many, at the same
time. We find that they do update their expectations about both speakers but that this is not a
long-lasting effect. Taken together, these results suggest that preschoolers engage in
speaker-specific adaptation and that they can use their prior exposure to a speaker’s utterances in
order to predict their future speech patterns, which demonstrates that children are attentive to
their conversational partners even at a very subtle level.

Chapter 2 focuses on the interconnectedness between labour market division, economic rents concentration, political extremism, and ethnic conflict. A natural experiment of history that occurred in the late 1960s in South Tyrol, a northernmost and predominantly German-speaking region of Italy, is exploited to investigate whether frictions in the labour market may induce a move in the voting preferences of a privileged minority group towards a more extremist political party. Chapter 3 builds on propositions from Latane’s Dynamic Social Impact Theory ´ (Latane, 1981, 1996) to analyse the evolution and diffusion ´ of anti-immigrant attitudes across European NUTS2 regions between 2002 and 2014. The identification of a spatially dependent diffusion and clustering process of anti-immigrant attitudes has a significant bearing for the understanding of the rise and fall of populist movements across Europe and changing electoral support for xenophobic parties across European regions over time. The last chapter explores the extent to which scientific migration and mobility barriers shape processes of scientific knowledge production and dissemination

description: We study the impacts of hydrogen (H2) infrastructure build-out to support the heavy-duty trucking industry in California as the state strives to reach zero-emission vehicle policy targets for emission reductions. We first review the current H2 production, transportation, refueling station, and vehicle technologies used today to foster a hydrogen economy and the technologies in the research and development phase that can accelerate the transition in the future. We then determine the energy and infrastructure impacts of a complete switch of heavy-duty duty vehicles (HDVs) (greater than 8,500 lbs) in California to fuel cell electric (FCEV) from gasoline and diesel fuel sources. Results show that about a 23% increase in natural gas consumption in the state would be required to transition HDVs in the state to FCEVs with steam methane reforming with carbon capture (SMR-CCS) hydrogen production. Alternatively, if the H2 is produced through electrolysis, a 50% increase in electricity generation for the state would be required. If the electricity input for electrolysis is only from installed solar photovoltaic, over four times more capacity than what is currently installed in-state would need to be dedicated to hydrogen production. Also, over two times as much hydrogen storage volume would be needed at H2 refueling stations in comparison to typical gasoline or diesel storage tanks at current gas stations. We next assess the optimal placement of hydrogen production facilities throughout the state to minimize the cost of H2 infrastructure to support HDVs. Qualitative results show that placing SMR-CCS production facilities in Northern California and electrolysis production facilities in Southern California is optimal. Through technoeconomic modeling efforts, we find that lower energy input costs, and larger production facility size yield most cost-effective hydrogen production, distribution, and dispensing costs with SMR-CCS being about $5/kg H2 less than electrolysis hydrogen production in Sacramento, California. Our future work will expand the technoeconomic model to include production costs in each county of California and will account for technology cost reductions as the hydrogen economy grows and technologies mature.
Modified Gradient Boosting in High-dimensional Nonlinear Regression

description: Herein we develop a modification of Freund and Schapire's (1997) AdaBoost algorithm for classification trees and Friedman's (2001) gradient boosting generalization. Not only does this modification address long-standing unresolved problems concerning convergence and when to terminate the iterative algorithms, but it is also shown to have optimality properties via attainment of the convergence rates of oracle benchmarks that are computationally infeasible. Simulation studies are presented to illustrate the key ideas underlying modified gradient boosting and how it works.

description: This study aims to assess the feasibility of building a smart cost-effective traffic management system using commercially available components. The benefits of these systems are not limited to traffic congestion reduction but also the employment of economic incentives that may change commuters’ patterns and behaviors. Based on the literature, the existing traffic management systems require costly roadside infrastructure changes. Therefore, a need has surfaced to create a cost-effective solution based on the intersection between technical feasibility, business viability, and public policy initiatives. The current study presents a prototype testing of the proposed system applied in Stanford Campus. These smart traffic demand management (TDM) systems can be applied in both private and public sectors through policy changes that foster efficient use of the existing infrastructure while creating an opportunity for revenue stream. The use of bidding and tradable token systems will allow ride-sharing, shipping companies, and individuals to access certain roads during times with high traffic demands. Finally, the study lists a set of recommendations, best practices, and a novel passenger routing scheme to adopt for the Los Angeles City council in order to address the anticipated traffic congestion associated with AVs when hosting the summer Olympic games in 2028.

subject: Food insecurity

description: Adequate food and nutrition are vital components of human wellbeing, which are compromised by food insecurity in many low-income populations, especially during the COVID- 19 pandemic. Measuring the impact of the pandemic on the overall health and wellbeing of food insecure older adults is crucial to lower the burden of food insecurity and further senior wellbeing during this challenging time. The primary aims of this research study are to assess the impact of food insecurity on physical health, mental health, and social wellbeing among low-income participants during the COVID-19 pandemic, comparing 2 study groups among the study sample. The study consists of a survey with 4 sections related to COVID-19, mental health, physical health, and emotional wellbeing during the pandemic, as well as an optional follow-up interview to further discuss personal experiences related to food insecurity and/or health. SPSS software was used for data analysis. Overall, Plaza Tower residents experienced a greater decline in all health and wellbeing measures compared to Heritage residents. Heritage residents had significantly lower scores for “health status in terms of diet and nutrition” and “social network” compared to Plaza Tower residents. Heritage residents also reported “unintentional weight loss” and “trouble staying full between meals” more often than the Plaza Tower group. The number of individuals living in the household of residents was significantly associated with “feeling lonely and isolated from others”.

description: The SmartCHP system combines a FPBO fuelled engine and flue gas boiler to produce electricity and heat at a high efficiency over the whole load range. A burner-boiler system is being developed which can be operated with pure FPBO or a mixture with up to 20% ethanol and flue gas from the engine with an oxygen content between 5 – 18%. The combustion of FPBO in flue gas has been extensively studied. A 17 kW and 100 kW burner were developed and experimentally investigated under different boundary conditions in water-cooled combustion chamber (boiler). The combustion of FPBO in flue gas and the quick start of the burner even at low flue gas temperatures down to a certain O2-limit (15% O2 at low flue gas temperatures) works very well. The flame speed decreases sharply with decreasing O2 contents. Low flame speeds make it difficult to stabilize the flame in the burner. The flue gas temperatures of up to 732 K limit the flame speed drop and will help to stabilize the flame at lower oxygen contents. Based on the requirements of the system, a boiler concept was developed, and the appropriate components were acquired.
