description: Combining different observational probes, such as galaxy clustering and weak lensing, is a promising technique for unveiling the physics of the Universe with upcoming dark energy experiments. The galaxy redshift sample from the Dark Energy Spectroscopic Instrument (DESI) will have a significant overlap with major ongoing imaging surveys specifically designed for weak lensing measurements: the Kilo-Degree Survey (KiDS), the Dark Energy Survey (DES) and the Hyper Suprime-Cam (HSC) survey. In this work we analyse simulated redshift and lensing catalogues to establish a new strategy for combining high-quality cosmological imaging and spectroscopic data, in view of the first-year data assembly analysis of DESI. In a test case fitting for a reduced parameter set, we employ an optimal data compression scheme able to identify those aspects of the data that are most sensitive to the cosmological information, and amplify them with respect to other aspects of the data. We find this optimal compression approach is able to preserve all the information related to the growth of structure; we also extend this scheme to derive weights to be applied to individual galaxies, and show that these produce near-optimal results.

description: This paper investigates the relationship between the income growth and the trend in industrial wastewater discharge in China during the period 1981-2007. For the data encompassing all the provinces over the entire period considered, both an inverted U-shaped EKC and an N-shaped EKC are statistically significant. An analysis dividing provinces into rich and poor groups reveals that the EKC relations are mainly governed by the rich province group. The EKC relations for the poor province group are either not found or are statistically weak. A further analysis based on dividing the data into before and after the year 2000 is in favour of the quadratic EKC model. The results of this study show that the relationships between a given pollutant and income are temporal and spatial specific depending on the driving forces behind. This implies that results derived from one study for certain regions/countries and for a specific time period may not be generalized for other regions/countries and extrapolated to other periods.

description: Architecture has to contribute to climate change recovering, by designing in a more responsible way respecting nature, local climatic, cultural, social and economic conditions, using the inexhaustible energy of the sun, wind, earth and water as Renewable energy Resources and existing local materials and resources as well. Making buildings more sustainable to time and space means that we also have to respect cultural heritage, the past, the present and the future. Architecture has also to ensure thermal comfort and healthy indoor environment during the whole year, while diminish conventional fuels consumption on the base of bioclimatic, energy efficient approach. Buildings in use or in course of erection account for over 50% of total greenhouse gas emissions. Consequently, upgrading old inefficient buildings so as to meet principles of bioclimatic design is an effective way to reduce energy use in industrialized countries. (Smith, 2005) However, refurbishment schemes should include both environmental design and conservation of architectural, historical and social values of old existing stock.

This paper consists of two parts. At first there is a review of the objectives, targets and studies regarding the old existing UK housing stock, in order to highlight the principles and advantages of bioclimatic design and energy efficient improvements to listed buildings’ fabric and services. The second part contains an evaluation of performance of the recently refurbished 17 St Augustine’s road Victorian House in London. Critical assessment of its current performance has been carried out according to winter and summer on site measurements, simulations and calculations in TAS and SAP softwares. This study will be focuses more on winter performance and annual heating fuel demands. Occupants’ behaviour and its impact on Low Energy Victorian Dwelling’s (LEVH) performance has also been investigated through a questionnaire survey, while the cost of refurbishment scheme is evaluated in terms of positive effectiveness to annual savings.

description: Dismantling allows for the removal of elements of a set, or in our case lattice, without disturbing the remaining structure. In this paper we have extended the notion of dismantling by single elements to the dismantling by intervals in a lattice. We utilize theory from Formal Concept Analysis (FCA) to show that lattices dismantled by intervals correspond to closed subrelations in the respective formal context, and that there exists a unique kernel with respect to dismantling by intervals. Furthermore, we show that dismantling intervals can be identified directly in the formal context utilizing a characterization via arrow relations and provide an algorithm to compute all dismantling intervals.

description: We study the ring of Weyl invariant $E_8$ weak Jacobi forms. Wang recently proved that the ring is not a polynomial algebra. We consider a polynomial algebra which contains the ring as a subset and clarify the necessary and sufficient condition for an element of the polynomial algebra to be a Weyl invariant $E_8$ weak Jacobi form. This serves as a new algorithm for constructing all the Jacobi forms of given weight and index. The algorithm is purely algebraic and does not require Fourier expansion. Using this algorithm we determine the generators of the free module of Weyl invariant $E_8$ weak Jacobi forms of given index $m$ for $m\le 20$. We also determine the lowest weight generators of the free module of index $m$ for $m\le 28$. Our results support the lower bound conjecture of Sun and Wang and prove explicitly that there exist generators of the ring of Weyl invariant $E_8$ weak Jacobi forms of weight $-4m$ and index $m$ for all $12\le m \le 28$.

description: Psychogeriatric patients are required by Dutch law to be supervised by a healthcare professional at all times during daycare. We investigated how technology can support healthcare professionals during these supervisory tasks. Our research shows that sensors and associated digital processing intelligence cannot be employed effective and efficient yet in these settings. The knowledge and the insights of the healthcare professional are of utmost importance to perform the supervision. Through repeated experimental research with a variety of sensors we found that the best sensor solution in this care context is a combination of two cameras and a microphone.

description: Quantum walks on graphs can model physical processes and serve as efficient tools in quantum information theory. Once we admit random variations in the connectivity of the underlying graph, we arrive at the problem of percolation, where the long-time behaviour appears untreatable with direct numerical methods. We develop novel analytic methods based on the theory of random unitary operations which help us to determine explicitly the asymptotic dynamics of quantum walks on 2D finite integer lattices with percolation. Based on this theory we find new unexpected features of percolated walks like asymptotic position inhomogeneity or special directional symmetry breaking.

description: The early and complete temporal characterization of optical, fast, transient sources requires continuous and multiband observations over different timescales (hours to months). For time-domain astronomy, using several telescopes to analyze single objects is the usual method, allowing the acquisition of highly sampled light curves. Taking a series of images each night helps to construct an uninterrupted chain of observations with a high cadence and low duty cycle. Speed is paramount, especially at early times, in order to capture early features in the light curve that help determine the nature of the observed transients and assess their astrophysical properties. However, the problem of rapidly extracting source properties (temporal and color evolution) with a heterogeneous data set remains. Consequently, we present Muphoten, a general and fast-computation photometric pipeline able to address these constraints. It is suitable for extracting transient brightness over multi-telescope and multiband networks to create a single homogeneous photometric time series. We show the performance of Muphoten with observations of the optical transient SN 2018cow (from 2018 June to 2018 July), monitored by the GRANDMA network and with the publicly available data of the Liverpool Telescope.

description: Estimating the likelihood, timing, and nature of events is a major goal of modeling stochastic dynamical systems. When the event is rare in comparison with the timescales of simulation and/or measurement needed to resolve the elemental dynamics, accurate prediction from direct observations becomes challenging. In such cases a more effective approach is to cast statistics of interest as solutions to Feynman-Kac equations (partial differential equations). Here, we develop an approach to solve Feynman-Kac equations by training neural networks on short-trajectory data. Our approach is based on a Markov approximation but otherwise avoids assumptions about the underlying model and dynamics. This makes it applicable to treating complex computational models and observational data. We illustrate the advantages of our method using a low-dimensional model that facilitates visualization, and this analysis motivates an adaptive sampling strategy that allows on-the-fly identification of and addition of data to regions important for predicting the statistics of interest. Finally, we demonstrate that we can compute accurate statistics for a 75-dimensional model of sudden stratospheric warming. This system provides a stringent test bed for our method.

description: This study uses an econometric approach to evaluate whether structural reforms in Latin America contributed to poverty and income inequality over the period from 1985 to 2000. Data on structural reforms is employed from the Inter-American Development Bank‟s Structural Policy Index, and poverty and income inequality data is obtained from the World Bank‟s PovcalNet database. Using a panel data analysis with controls for GDP per-capita and political institutions, the overall openness level is found to be significantly positively related to the percent of the population living under the poverty line, the poverty gap, the Gini coefficient, the income ratio of the richest to poorest deciles of the population, and the mean log deviation. Specific reforms that are significantly positively related to poverty and/or inequality include privatizations and financial deregulation. Trade liberalization, average income, and democratic institutions demonstrate a negative, albeit weak, relationship to poverty and inequality.

description: Magic-angle twisted bilayer graphene (MATBG) hosts a number of correlated states of matter that can be tuned by electrostatic doping. Superconductivity has drawn considerable attention and the mechanism behind it is a topic of active discussion. MATBG has been experimentally characterized by numerous transport and scanning-probe experiments. The material has also emerged as a versatile platform for superconducting electronics, as proven by the realization of monolithic Josephson junctions. However, even though phase-coherent phenomena have been measured, no control of the superconducting phase has been demonstrated so far. Here, we present a Superconducting Quantum Interference Device (SQUID) in MATBG, where the superconducting phase difference is controlled through the magnetic field. We observe magneto-oscillations of the critical current, demonstrating long-range coherence agreeing with an effective charge of 2e for the superconducting charge carriers. We tune to both asymmetric and symmetric SQUID configurations by electrostatically controlling the critical currents through the junctions. With this tunability, we study the inductances in the device, finding values of up to 2μH. Furthermore, we directly observe the current-phase relation of one of the Josephson junctions of the device. Our results show that superconducting devices in MATBG can be scaled up and used to reveal properties of the material. We expect this to foster a more systematic realization of devices of this type, increasing the accuracy with which microscopic characteristics of the material are extracted. We also envision more complex devices to emerge, such as phase-slip junctions or high kinetic inductance detectors.

description: Meat cutting has since long shown high frequencies of work-related disorders and injuries. The meat cutting industry initiated an interactive research project to assist the companies in creating a better work environment considering also the profitability. After an initial diagnosis, a broad strategy was formed and four mixed groups focusing personal development, technological developments, work organization and work environment started working. The results from these further initiated focused studies that were performed in close interaction with the industry. During the four year project a continuous reduction of musculoskeletal disorder problems in the industry and other substantial effects were observed.
Revisiting Stokes’ Theory of Slums : Towards Decolonised Housing Concepts from the Global South

description: Recently, large-scale housing programmes have experienced a revival in many countries of the Global South. They are criticised for their top-down, standard-ised, and supply-driven nature, which hardly meets people’s demands. At the heart of the problem lies the concept of “material decency”—a normative and shelter-centric notion of housing, inspired by colonial planning and developmentalist thought. Many African housing programmes confuse “material decency” with the demand-driven, bottom-up concept, of adequate housing. Following this, the stigmatisation of auto-constructed neighbourhoods prevails and housing is primarily reduced to a question of material shelter. Adding to significant contributions about the need for southern perspectives on urban planning, this chapter offers an alternative entry point by revis-iting Stokes’ A Theory of Slums published in 1962. Interestingly, Stokes’ theory did not deal with housing directly but focused on “slum” dwellers’ socioeconomic inte-gration and structural factors of exclusion. I argue to re-interpret Stokes’ notion of barriers to social escalation as a structural discrimination of “slum” dwellers. Such stigmatisation may be read as a major reason behind the proliferation of so-called slums. Based on the author’s fieldwork in Morocco and additional literature, the aim is to deconstruct the role of “material decency” and to offer pathways towards decolonised housing concepts from the Global South. For this purpose, the chapter suggests five cornerstones of adequate housing, namely subjectivity, non-materiality, flexibility, contextuality, and choice.

Topics in the theory of enriched accessible categories
Creators: name: Tendas, Giacomo
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: The aim of this thesis is to further develop the theory of accessible categories in the enriched context. We study and compare the two notions of accessible and conically accessible 𝒱-categories, both arising as free cocompletions of small 𝒱-categories: the former under flat-weighted colimits and the latter under filtered colimits. These two notions are not the same in general, however we show that they coincide for many significant bases of enrichment such as Cat and SSet, and differ just by Cauchy completeness for many algebraic examples including Ab, R-Mod and GAb. We then provide new characterization theorems for these by considering some notions of virtual orthogonality and virtual reflectivity which generalize the usual reflectivity and orthogonality conditions for locally presentable categories. The word virtual refers to the fact that the reflectivity and orthogonality conditions are given in the free completion of the 𝒱-category involved under small limits, instead of the 𝒱-category itself. We then prove that the 2-category of accessible 𝒱-categories, accessible 𝒱-functors, and 𝒱-natural transformations has all flexible limits. In the final chapters we study, characterize, and provide duality theorems in the setting of accessible 𝒱-categories with limits of a specified class Ψ; in this context, instead of the free completion under small limits, we consider “free completions” under a specific type of colimits ℭ for which, in particular, ℭ-colimits commute in 𝒱 with Ψ-limits. This allows us to capture the theories of weakly locally presentable, locally multipresentable, locally polypresentable, and accessible categories as instances of the same general framework.

description: We excite YbF molecules to low-lying vibrational levels of the $A^2Π_{1/2}$ state, and of the nearby perturber state sometimes called [18.6]0.5. By dispersing the fluorescence, we measure branching ratios for the radiative decay to vibrational levels of the $X^2Σ^+$ state. These ratios help to determine the optimum laser cooling scheme for the molecule. Our results establish the practicality of a scheme that was previously suggested [Tarbutt et al., New J. Phys. 15 (2013) 053034] and show how the scheme can be modified to provide a stronger radiative cooling force.

description: Emphasising implicit assumptions behind our ways of seeing ‘slums’, this essay calls for a radical understanding of ‘ordinary neighbourhoods’. Borrowing from Robinson’s ‘ordinary cities’ concept, it conceptualises ‘ordinariness’ as a way of rejecting the ‘absolute otherness’ of slums, stressing heterogeneity within and between neighbourhoods as well as the significance of comparative empirical research. Beyond the need for alternative, less stigmatised terms, the article urges for a new territorial ethics, a radical deconstruction and de-mystification of the ‘slum’. Such conceptualisation should make aware of the term ‘slum’ as a non-physical, spatially detached social construct that discredits marginalised people and diverts attention away from precarious living conditions and possible ways of improving them.

description: In this work, we introduce a stochastic maximum principle (SMP) approach for solving the reinforcement learning problem with the assumption that the unknowns in the environment can be parameterized based on physics knowledge. For the development of numerical algorithms, we shall apply an effective online parameter estimation method as our exploration technique to estimate the environment parameter during the training procedure, and the exploitation for the optimal policy will be achieved by an efficient backward action learning method for policy improvement under the SMP framework. Numerical experiments will be presented to demonstrate that our SMP approach for reinforcement learning can produce reliable control policy, and the gradient descent type optimization in the SMP solver requires less training episodes compared with the standard dynamic programming principle based methods.

description: The idea of indigenous populations around the world as “noble savages” dominated literature for much of the 20th century.  Further research into different tribes’ environmental practices as well as their integration into the market economy has begun to change this view.  In Ecuadorian Amazon, the Huaorani are the most recently assimilated group, with some sub-groups still resisting contact with the outside.  With vast reserves of oil present under Huaorani land, this indigenous group has quickly become integrated into national and international markets.  The focus of this study is on one Huaorani community, Gareno, which is located along an oil road within the Amazon.  Community members were interviewed in order to better understand why they lived along the oil road and how they felt it impacted their daily lives.  Responses showed that the residents have chosen to live and stay in Gareno because of the health and education opportunities and ease of transport, but also because this area is ancestral territory.  In addition, they left former villages, which were deep inside the forest, due to social conflict. It is notable that these push and pull factors complicate the notion of “noble savages” (who either continue to be isolated from the market or are unable to cope with it) and highlight indigenous agency and decision-making during a period of rapid cultural, economic, and ecological change.  As the people of Gareno look to further improve their quality of life through development, it is important to foster more nuanced views of indigenous peoples to not only devise appropriate conservation and development policies but also to prevent a backlash when they do not conform to idealized Western images.

description: We apply ultrafast X-ray diffraction with femtosecond temporal resolution to monitor the lattice dynamics in a thin film of multiferroic BiFeO$_3$ after above-bandgap photoexcitation. The sound-velocity limited evolution of the observed lattice strains indicates a quasi-instantaneous photoinduced stress which decays on a nanosecond time scale. This stress exhibits an inhomogeneous spatial profile evidenced by the broadening of the Bragg peak. These new data require substantial modification of existing models of photogenerated stresses in BiFeO$_3$: the relevant excited charge carriers must remain localized to be consistent with the data.

Unlike classi cation, in clustering one has to rst decide the optimum number of clusters and then assign the objects into different clusters. Solution of such problems for a large number of high dimensional data points is quite complicated and most of the existing algorithms will not perform properly. In the present work a new clustering technique applicable to large data set has been used to cluster the spectra of 702248 galaxies and quasars having 1540 points in wavelength range imposed by the instrument. The proposed technique has successfully discovered ve clusters from this 702248X1540 data matrix.

Required toroidal confinement for fusion and omnigeneity

description: Deuterium-tritium (DT) burning requires a long energy confinement times compared to collision times, so the particle distribution functions must approximate local-Maxwellians. Non-equilibrium thermodynamics is applicable, which gives relations among transport, entropy production, the collision frequency, and the deviation from a Maxwellian. The distribution functions are given by the Fokker-Planck equation, which is an advection-diffusion equation. A large hyperbolic operator, the Vlasov operator with the particle trajectories as its characteristics, equals a small diffusive operator, the collision operator. The collisionless particle trajectories would be chaotic in stellarators without careful optimization. This would lead to rapid entropy production and transport -- far beyond what is consistent with a self-sustaining DT burn. Omnigeneity is the weakest general condition that is consistent with a sufficiently small entropy production associated with the thermal particle trajectories. Omnigeneity requires that the contours of constant magnetic field strength be unbounded in at least one of the two angular coordinates in magnetic surfaces and that there be a symmetry in the field-strength wells along the field lines. Even in omnigenous plasmas, fluctuations due to microturbulence can produce chaotic particle trajectories and the gyro-Bohm transport seen in many stellarator and tokamak experiments. The higher the plasma temperature above 10~keV, the smaller the transport must be compared to gyro-Bohm for a self-sustaining DT burn. The hot alphas of DT fusion heat the electrons. When the ion-electron equilibration time is long compared to the ion energy confinement time, a self-sustaining DT burn is not possible, which sets a limit on the electron temperature.

An often-unnoticed face of HIV in Tanzania is distinctly agrarian. For farming communities in the Arusha area of Tanzania, the connection between food security and HIV is hard to ignore.

About 8 out of 100 people in Tanzania are living with the virus. Livelihoods claimed by the HIV epidemic are increasingly young men and women whose families depend on their labor on family-run gardens and farms. A trend toward young people migrating from their rural communities for life in urban centers has been well documented in the last ten years. This trend, combined with HIV infection rates among the young, have a crippling effect on food security in the isolated hills outside Arusha. Whole communities struggle with drops in local food production, loss of market opportunities, and high imported food costs.

Women comprise the majority of Tanzanian food producers in rural settings – roughly 90% of women in Arusha district engage in subsistence farming and market activities every day. As the HIV epidemic reaches more and more rural areas, women bear newer roles as farmers, breadwinners, and caretakers to those family or community members with HIV.

Global Service Corps (GSC) is a San Francisco-based non-profit that facilitates HIV education workshops and bio-intensive agriculture trainings for people in the Arusha area, making the critical connection between HIV prevention and sustainable farming. Trainings stress a multi-generational, family-centered approach to HIV prevention, and include discussions around sexual decision-making, negotiation, and condom use. Most recently, GSC has launched HIV-prevention day camps for secondary school students to help them stay HIV-free.

Bio-intensive agriculture (BIA) trainings instruct on sack-gardening, crop rotation, companion planting, and other labor-saving farming techniques. These trainings also emphasize family nutrition and sustained crop yield.

Numbers of people in the Arusha community receiving both BIA and HIV trainings are on the rise. Embracing an ecological perspective in the fight against HIV and food insecurity, Global Service Corps’ operations set a sustainable example for integrating disciplines on the ground for improved quality of life.
Dark Matter and Neutrino Masses in a Portalino-like Model

description: We explore a Portalino-like model of dark matter and neutrino masses in which right-handed neutrino fields connect gauge neutral operators from the Standard Model and Hidden Sector. Neutrino masses are generated via a seesaw-like mechanism that can explain the light active neutrino masses. The model includes a ``Portalino'' state that connects the two sectors via the neutrino portal. Dark Matter in this model consists of a hidden sector Dirac fermion that dominantly freezes-out via resonant annihilations into other hidden sector states, which ultimately results in a population of Portalinos. Due to small mixing in the extended neutrino sector these Portalinos tend to be cosmologically long lived, decaying into Standard Model particles leading to constraints on the model from Big Bang Nucleosynthesis and measurements of the Cosmic Microwave Background radiation. Combining these limits with direct constraints on the size of the Portalino-neutrino mixing and the assumptions of the model the viable mass ranges for the Portalino states are found to be 0.02 eV $\lesssim m_n \lesssim$ 6.4 eV or 489 MeV $\lesssim m_n \lesssim$ TeV. Indirect dark matter signals in the form of highly boosted, mono-energetic Portalinos produced in Dark Matter annihilations provide a target for neutrino telescopes.
description: 36 pages, 6 figures. Improved analysis in Section 5.1 (Heavy Portalino Case) to include numerical treatment of decay width/decoupling temperature relation, results included in an updated version of figure 5. Expanded discussion of the model's indirect signals added. Matches published version
Metrics for Evaluating Social Conformity of Crowd Navigation Algorithms

description: Recent protocols and metrics for training and evaluating autonomous robot navigation through crowds are inconsistent due to diversified definitions of "social behavior". This makes it difficult, if not impossible, to effectively compare published navigation algorithms. Furthermore, with the lack of a good evaluation protocol, resulting algorithms may fail to generalize, due to lack of diversity in training. To address these gaps, this paper facilitates a more comprehensive evaluation and objective comparison of crowd navigation algorithms by proposing a consistent set of metrics that accounts for both efficiency and social conformity, and a systematic protocol comprising multiple crowd navigation scenarios of varying complexity for evaluation. We tested four state-of-the-art algorithms under this protocol. Results revealed that some state-of-the-art algorithms have much challenge in generalizing, and using our protocol for training, we were able to improve the algorithm's performance. We demonstrate that the set of proposed metrics provides more insight and effectively differentiates the performance of these algorithms with respect to efficiency and social conformity.
Working environment committees – stretched between strategy and participation

description: In Denmark, the Working Environment Act was revised in 2010. The intention was that increased flexibility in the structure and operations of the legally required safety and working environment committees would enable a more systematic approach and lead to integration of working environment issues in strategic decisions in companies. In this paper we discuss the development by presenting four case studies from a larger case sample drawn from two research projects. We discuss whether this change towards flexibility, systematization, and strategy is conducive or prohibitive in relation to ambitions of making the working environment organization better at dealing with psychosocial working environment problems, and maintaining a high level of employee participation, and proximity between committees and local workplaces.

These photographs come from a long-term and ongoing project concerned with how we perceive and are affected by changes in the places we inhabit. New Orleans finds itself in a precarious position relative to the “natural” demands of its geographic location. Eighty percent of the city was flooded in 2005; as many of us now realize, most of the city is located below the level of the water that borders it. Due to where it is physically located, in 50 years New Orleans will most likely look nothing like it does today.Coincident to or perhaps because of its location, New Orleans has developed an identity that represents a diversion from the cultural norms associated with mainstream America. Known as the Big Easy for the ease with which musicians could find work, it displays front and center its difference from the rest of America during its celebration of Mardi Gras. What should be an obvious truth, that a place’s physical location and features have a profound affect on the lives and outlooks of its inhabitants, is often overlooked. Saying we live “in” a place, rather than “on” or “with” it, concedes how entirely a place encompasses us physically. It acknowledges the pervasive affect the place’s external imperatives have upon our psyches, our perceptions of self and others, and the desires we pursue.Now that popular consensus is embracing the fact that our world is growing warmer, the uncertain futures this city faces today may well be a harbinger of change facing the places we all live in. Has a sequence of events already been set in motion that will irrevocably alter how and where all of us will be able to live? And if so, how will this fact affect how we relate to each other and to the places we inhabit?These photographs describe relationships between elements in the landscape that are specific to a particular day, hour, and fraction of a second. What is important to keep in mind is that each triptych presented here comprises a series of individual and distinct photographs. Each individual “frame” within the triptych is its own point in time and each corresponds to a distinct piece of film that I exposed. Taking in the scene presented by the triptych is analogous to how each of us encounters a prospect. By pausing slightly and regularly we set into motion a mental “imagining” in order to see things more completely. I hope each piece’s particularity, its reference to a specific location in time as well as space, stimulates speculation about how different that place appears at this very moment, were you able to behold it for yourself. And more exciting is to ponder what it might look like tomorrow, next month, and 50 years hence.
