title: The Identification of Key Economic and Property Variables that Impact on Prime Office Rents: a Study of Seven European Cities
Creators: name: O'Reilly, Aoife
Publisher: name: Technological University Dublin
Year: 2014

description: The aim of this dissertation is to identify and assess the impact of macroeconomic and property variables on prime office rental levels. Data from seven diverse European cities was gathered from 2000 to 2014 and statistical analysis using econometric modelling was undertaken. The results unveil a number of relationships between the explanatory variables and prime office rents. In particular, the results highlight movements in the office vacancy rate and GDP as important variables impacting change in prime office rental levels while employment, interest rates and inflation play a less significant role. Results indicate that econometric modelling has a role to play in investment decision making and transnational studies such as this may prove useful for investment portfolio diversification. Like many social science econometric studies, a number of limitations are encountered such as the use of headline rents where effective rents would provide a more accurate reflection of the office market. This limitation is common to the majority of the studies in this area due to restrictions on data availability in the industry. The findings of the study should add to the existing body of knowledge on the subject area and prove useful to investors operating increasingly globalised portfolio strategies.

description: While the formal valence and charge state concepts have been tremendously important in materials physics and chemistry, their very loose connection to actual charge leads to uncertainties in modeling behavior and interpreting data. We point out, taking several transition metal oxides (La$_2$VCuO$_6$, YNiO$_3$, CaFeO$_3$, AgNiO$_2$, V$_4$O$_7$) as examples, that while dividing the crystal charge into atomic contributions is an ill-posed activity, the 3d occupation of a cation (and more particularly, differences) is readily available in first principles calculations. We discuss these examples, which include distinct charge states and charge-order (or disproportionation) systems, where different "charge states" of cations have identical 3d orbital occupation. Implications for theoretical modeling of such charge states and charge-ordering mechanisms are discussed.

description: Multi-task model training has been adopted to enable a single deep neural network model (often a large language model) to handle multiple tasks (e.g., question answering and text summarization). Multi-task training commonly receives input sequences of highly different lengths due to the diverse contexts of different tasks. Padding (to the same sequence length) or packing (short examples into long sequences of the same length) is usually adopted to prepare input samples for model training, which is nonetheless not space or computation efficient. This paper proposes a dynamic micro-batching approach to tackle sequence length variation and enable efficient multi-task model training. We advocate pipeline-parallel training of the large model with variable-length micro-batches, each of which potentially comprises a different number of samples. We optimize micro-batch construction using a dynamic programming-based approach, and handle micro-batch execution time variation through dynamic pipeline and communication scheduling, enabling highly efficient pipeline training. Extensive evaluation on the FLANv2 dataset demonstrates up to 4.39x higher training throughput when training T5, and 3.25x when training GPT, as compared with packing-based baselines. DynaPipe's source code is publicly available at https://github.com/awslabs/optimizing-multitask-training-through-dynamic-pipelines.

description: Recent investigations suggest that both spin-orbit coupling and electron correlation play very crucial roles in the $5d$ transition metal oxides. By using the generalized Gutzwiller variational method and dynamical mean-field theory with the hybridization expansion continuous time quantum Monte Carlo as impurity solver, the three-band Hubbard model with full Hund's rule coupling and spin-orbit interaction terms, which contains the essential physics of partially filled $t_{2g}$ sub-shell of $5d$ materials, is studied systematically. The calculated phase diagram of this model exhibits three distinct phase regions, including metal, band insulator and Mott insulator respectively. We find that the spin-orbit coupling term intends to greatly enhance the tendency of the Mott insulator phase. Furthermore, the influence of the electron-electron interaction on the effective strength of spin-orbit coupling in the metallic phase is studied in detail. We conclude that the electron correlation effect on the effective spin-orbit coupling is far beyond the mean-field treatment even in the intermediate coupling region.

description: The recent preliminary findings of this year’s census have thrown up some curious housing results. A little numbercrunching shows that we’ve not been adding as many houses each year as headline figures would suggest. Official completion numbers tell us that between 2011 and 2016, just 18,981 additional houses—or 0.94%—were added to the state’s overall housing stock, or an average of 3,796 a year. For comparison, at the 2006 census we had added 21%, and in 2011 it was 13%. We have effectively not increased our national housing stock in the past six years.

description: In the early days of the web, giving the same web page to different browsers could provide very different results. As the rendering engine behind each browser would differ, some elements of a page could break or be positioned in the wrong location. At that time, the User Agent (UA) string was introduced for content negotiation. By knowing the browser used to connect to the server, a developer could provide a web page that was tailored for that specific browser to remove any usability problems. Over the past three decades, the UA string remained exposed by browsers, but its current usefulness is being debated. Browsers now adopt the exact same standards and use the same languages to display the same content to users, bringing the question if the content of the UA string is still relevant today, or if it is a relic of the past. Moreover, the diversity of means to browse the web has become so large that the UA string is one of the top contributors to tracking users in the field of browser fingerprinting, bringing a sense of urgency to deprecate it. In this paper, our goal is to understand the impact of the UA on the web and if this legacy string is still actively used to adapt the content served to users. We introduce UA-Radar, a web page similarity measurement tool that compares in-depth two web pages from the code to their actual rendering, and highlights the similarities it finds. We crawled 270, 048 web pages from 11, 252 domains using 3 different browsers and 2 different UA strings to observe that 100% of the web pages were similar before any JavaScript was executed, demonstrating the absence of differential serving. Our experiments also show that only a very small number of websites are affected by the lack of UA information, which can be fixed in most cases by updating code to become browser-agnostic. Our study brings some proof that it may be time to turn the page on the UA string and retire it from current web browsers.

description: Resumen abstracto:

En este trabajo se presenta la Teoría Integrada del Objeto Primordial de Anticurvatura y el Origen del Universo (OPA), una propuesta cosmológica que replantea el mecanismo detrás del Big Bang. La teoría postula la existencia de un objeto primordial masivo con propiedades intrínsecas de antigravedad o anticurvatura, denominado "objeto negro." (Por el momento) A diferencia de la materia convencional que curva el espacio-tiempo atrayéndolo, este objeto ejerce una fuerza repulsiva que podría estar relacionada con la energía oscura y la aceleración de la expansión del universo.

 

Se propone que antes del Big Bang, el universo estaba en un estado de contracción extrema, gobernado por la gravedad convencional. Sin embargo, al alcanzar un umbral crítico de densidad y bajo la influencia de intensas fluctuaciones cuánticas, el objeto primordial activó su potencial repulsivo, desencadenando la expansión del espacio-tiempo. Esta activación no implica una explosión convencional, sino una transición de contracción a expansión impulsada por la anticurvatura.

 

La teoría explica fenómenos cosmológicos como la expansión acelerada actual y la distribución heterogénea de la materia, atribuyéndolos a la influencia residual de este objeto primordial combinado con interacciones gravitacionales convencionales. Además, se discute cómo la antigravedad podría vincularse con conceptos como la energía negativa y la materia exótica.

 

Esta hipótesis invita a replantear el origen del universo desde una perspectiva que integra elementos de la relatividad general y la mecánica cuántica, sugiriendo nuevas vías para investigar el papel de la energía oscura y la estructura a gran escala del cosmos.

description: Annealing has proven highly successful in finding minima in a cost landscape. Yet, depending on the landscape, systems often converge towards local minima rather than global ones. In this Letter, we analyse the conditions for which annealing is approximately successful in finite time. We connect annealing to stochastic thermodynamics to derive a general bound on the distance between the system state at the end of the annealing and the ground state of the landscape. This distance depends on the amount of state updates of the system and the accumulation of non-equilibrium energy, two protocol and energy landscape dependent quantities which we show are in a trade-off relation. We describe how to bound the two quantities both analytically and physically. This offers a general approach to assess the performance of annealing from accessible parameters, both for simulated and physical implementations.

By using variational methods, we prove the existence of infinitely many solutions. Our argument relies on the application of a generalized variant fountain theorem for strongly indefinite functionals. Previous results in the topic are improved.

description: Stress is a common trigger of seizures in people with epilepsy (PWE) and can lead to neuroendocrine impairments. The stress-response system can be affected by seizures and epilepsy. PWE frequently experience depression and are treated with antidepressants. However, antidepressants may increase the risk of development of epilepsy and affect epilepsy outcomes. I showed that epilepsy does not impair the stress-response system, although disturbances related to depression were found. Moreover, I showed that acute stress exerted antiseizure effects in some individuals. Finally, I provided evidence that antidepressants do not increase incidence of epilepsy and do not worse behavioural outcomes of epilepsy.

description: Housing is a many-headed beast with elements of technology, planning, finance, sociology and of course, politics. At its core, however, it is a simple thing: buildings for people and this is why it’s crucial to keep an eye on our population statistics. Preliminary results fromthe recent census are throwing up some interesting figures, all of which have implications for where we should be focusing our efforts to build housing. The location of our empty houses should have told us by nowthat there’s little point in building homes where there’s no demand for them.

description: Annealing is the process of gradually lowering the temperature of a system to guide it towards its lowest energy states. In an accompanying paper [Luo et al. Phys. Rev. E 108, L052105 (2023)], we derived a general bound on annealing performance by connecting annealing with stochastic thermodynamics tools, including a speed-limit on state transformation from entropy production. We here describe the derivation of the general bound in detail. In addition, we analyze the case of simulated annealing with Glauber dynamics in depth. We show how to bound the two case-specific quantities appearing in the bound, namely the activity, a measure of the number of microstate jumps, and the change in relative entropy between the state and the instantaneous thermal state, which is due to temperature variation. We exemplify the arguments by numerical simulations on the SK model of spin-glasses.

description: The landslide flow, introduced in [5], is a smoother analog of the earthquake flow on Teichmüller space which shares some of its key properties. We show here that further properties of earthquakes apply to landslides. The landslide flow is the Hamiltonian flow of a convex function. The smooth grafting map $sgr$ taking values in Teichmüller space, which is to landslides as grafting is to earthquakes, is proper and surjective with respect to either of its variables. The smooth grafting map $SGr$ taking values in the space of complex projective structures is symplectic (up to a multiplicative constant). The composition of two landslides has a fixed point on Teichmüller space. As a consequence we obtain new results on constant Gauss curvature surfaces in 3-dimensional hyperbolic or AdS manifolds. We also show that the landslide flow has a satisfactory extension to the boundary of Teichmüller space.

In accordance with our numerical predictions, the transport directions of the enantiomers depend very sensitively on the orientation of the lattice relatively to the fluid flow.

description: Contextuality is a foundational phenomenon underlying key differences between quantum theory and classical realistic descriptions of the world. Here we propose an experimental test which is capable of revealing contextuality in all qutrit systems, except the completely mixed state, provided we choose the measurement basis appropriately. The 3-level system is furnished by the polarization and spatial degrees of freedom of a single photon, which encompass three orthogonal modes. Projective measurements along rays in the 3-dimensional Hilbert space are made by linear optical elements and detectors which are sensitive to a single mode. We also discuss the impact of detector inefficiency and losses and review the theoretical foundations of this test.

We then define a type reconstruction algorithm that issound and terminating. This yields a system in which unannotated functions are given polymorphic types(thanks to Hindley-Milner) that can express the overloaded behavior of the functions they type (thanks tothe intersection introduction rule) and that are deduced by applying advanced techniques of type narrowing(thanks to the union elimination rule). This makes the system a prime candidate to type dynamic languages.

The authors start from renormalized second-order perturbation theory in the Coulomb repulsion in the particle-hole symmetric impurity Anderson model. The reported lesser self-energy is compared with the correct one, and with an analytic result valid for small frequency and applied voltage. As a consequence of the mistakes, the conservation of the current is not established and the results are unreliable.

description: We derive criteria for whether two cosmological events can have a shared causal past or a shared causal future, assuming a Friedmann-Lemaitre-Robertson-Walker universe with best-fit ΛCDM cosmological parameters from the Planck satellite. We further derive criteria for whether either cosmic event could have been in past causal contact with our own worldline since the time of the hot "big bang", which we take to be the end of early-universe inflation. We find that pairs of objects such as quasars on opposite sides of the sky with redshifts z >= 3.65 have no shared causal past with each other or with our past worldline. More complicated constraints apply if the objects are at different redshifts from each other or appear at some relative angle less than 180 degrees, as seen from Earth. We present examples of observed quasar pairs that satisfy all, some, or none of the criteria for past causal independence. Given dark energy and the recent accelerated expansion, our observable universe has a finite conformal lifetime, and hence a cosmic event horizon at current redshift z = 1.87. We thus constrain whether pairs of cosmic events can signal each other's worldlines before the end of time. Lastly, we generalize the criteria for shared past and future causal domains for FLRW universes with nonzero spatial curvature.

Ultra-quantum coherent states in a single finite quantum system

Year: 2023
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A set of $n$ coherent states is introduced in a quantum system with $d$-dimensional Hilbert space $H(d)$. It is shown that they resolve the identity, and also have a discrete isotropy property. A finite cyclic group acts on the set of these coherent states, and partitions it into orbits. A $n$-tuple representation of arbitrary states in $H(d)$, analogous to the Bargmann representation, is defined. There are two other important properties of these coherent states which make them `ultra-quantum'. The first property is related to the Grothendieck formalism which studies the `edge' of the Hilbert space and quantum formalisms. Roughly speaking the Grothendieck theorem considers a `classical' quadratic form ${\mathfrak C}$ that uses complex numbers in the unit disc, and a `quantum' quadratic form ${\mathfrak Q}$ that uses vectors in the unit ball of the Hilbert space. It shows that if ${\mathfrak C}\le 1$, the corresponding ${\mathfrak Q}$ might take values greater than $1$, up to the complex Grothendieck constant $k_G$. ${\mathfrak Q}$ related to these coherent states is shown to take values in the `Grothendieck region' $(1,k_G)$, which is classically forbidden in the sense that ${\mathfrak C}$ does not take values in it. The second property complements this, showing that these coherent states violate logical Bell-like inequalities (which for a single quantum system are quantum versions of the Frechet probabilistic inequalities). In this sense also, our coherent states are deep into the quantum region.

title: Predicting cyanobacteria blooms in 50 lakes of Northwest Washington
Creators: name: Llewellyn, Chandra Terezina
Publisher: name: Western Washington University
Year: 2010

description:
Eutrophication is one of the foremost problems affecting our freshwater resources. Excessive nutrient loading impacts freshwater lakes by altering ecosystem processes and degrading water quality, often resulting in human-induced eutrophication. Worldwide, cyanobacteria blooms occur in many anthropogenically eutrophic lakes. Such blooms are of increasing concern in the Pacific Northwest because they negatively affect lake system and function. A major concern is their unpredictable production of toxins, which can be deadly to animals, including humans. Therefore, an improved understanding of the incidence and persistence of cyanobacteria blooms is a critical aspect of protecting our water supply. The goal of this thesis was to attempt to create a predictive model based on simple water quality characteristics that would classify lakes according to bloom status using a multivariate statistical approach. Additional possible bloom contributors such as, light availability, landscape properties, N:P ratios or other interactive effects were not investigated in this study. During 2007-2009, 50 lakes in Northwest Washington were sampled to measure standard water quality (water chemistry) parameters as part of the Institute of Watershed Studies' (IWS) small lakes monitoring project. In addition, algal samples were collected during 2007-2009. The IWS study created a water quality baseline for many previously unmonitored lakes and revealed that a number of lakes experienced cyanobacteria blooms. Previous studies have used high phosphorus as an indicator of cyanobacteria blooms. I tested phosphorus, as well as chlorophyll, as possible indicators of cyanobacteria blooms. Based on hierarchical, Kmeans and non-metric clustering, the lakes sampled by IWS can be clustered into two groups based on differences in conductivity, alkalinity, total phosphorus and turbidity. However, chlorophyll and phosphorus concentrations did not predict lakes that were dominated by cyanobacteria blooms. High phosphorus levels were usually associated with high chlorophyll levels, but high chlorophyll levels were not always associated with cyanobacteria dominance. Using the water chemistry, data high phosphorus was a good indicator of algal blooms, but could not be used as an exclusive predictor of cyanobacteria blooms. Linear discriminants analysis was used to build a predictive model based on the 2007-2008 water quality data to try to classify the 2009 samples by cyanobacteria dominance. The model was unsuccessful (30% success rate) in predicting cyanobacteria blooms within the 2009 data. Despite the fact that algal blooms are fairly predictable using water chemistry data, this study highlights the complexity of predicting harmful cyanobacteria blooms in the Pacific Northwest.

description: We present a study of the evolution of several classes of MgII absorbers, and their corresponding FeII absorption, over a large fraction of cosmic history: 2.3 to 8.7 Gyrs from the Big Bang. Our sample consists of 87 strong (Wr(MgII)>0.3 A) MgII absorbers, with redshifts 0.21 A) with small ratios of equivalent widths of FeII to MgII. At high z, very strong MgII absorbers with both small and large Wr(FeII)/Wr(MgII) values are present. We compare our findings to a sample of 100 weak MgII absorbers (Wr(MgII)<0.3 A) found in the same quasar spectra by Narayanan et al. (2007). The main effect driving the evolution of very strong MgII systems is the difference between the kinematic profiles at low and high redshifts. At high z, we observe that, among the very strong MgII absorbers, all of the systems with small ratios of Wr(FeII)/Wr(MgII) have relatively large velocity spreads, resulting in less saturated profiles. At low z, such kinematically spread systems are absent, and both FeII and MgII are saturated, leading to Wr(FeII)/Wr(MgII) values that are all close to 1. The high redshift, small Wr(FeII)/Wr(MgII) systems could correspond to sub-DLA systems, many of which have large velocity spreads and are possibly linked to superwinds in star forming galaxies. In addition to the change in saturation due to kinematic evolution, the smaller Wr(FeII)/Wr(MgII) values could be due to a lower abundance of Fe at high z, which would indicate relatively early stages of star formation in those environments.

description: Fungicide mixtures produced by the agrochemical industry often contain low-risk fungicides, to which fungal pathogens are fully sensitive, together with high-risk fungicides known to be prone to fungicide resistance. Can these mixtures provide adequate disease control while minimizing the risk for the development of resistance? We present a population dynamics model to address this question. We found that the fitness cost of resistance is a crucial parameter to determine the outcome of competition between the sensitive and resistant pathogen strains and to assess the usefulness of a mixture. If fitness costs are absent, then the use of the high-risk fungicide in a mixture selects for resistance and the fungicide eventually becomes nonfunctional. If there is a cost of resistance, then an optimal ratio of fungicides in the mixture can be found, at which selection for resistance is expected to vanish and the level of disease control can be optimized.

description: We present a sound and complete focusing calculus for the core of the logic behind the proof assistant Beluga as well as an overview of its implementation as a tactic in Beluga's interactive proof environment Harpoon. The focusing calculus is designed to construct uniform proofs over contextual LF and its meta-logic in Beluga: a dependently-typed first-order logic with recursive definitions. The implemented tactic is intended to complete straightforward sub-cases in proofs allowing users to focus only on the interesting aspects of their proofs, leaving tedious simple cases to Beluga's theorem prover. We demonstrate the effectiveness of our work by using the tactic to simplify proving weak-head normalization for the simply-typed lambda-calculus.

title: Optimization of solid oxide fuel cell interconnect design
Creators: name: Pulagam, Krishna C.

description: Performance of solid oxide fuel cells (SOFC) is dependent of a set of complex physical and chemical processes occurring simultaneously. Interconnect for SOFC is important as it provides electrical connection between anode of one individual cell to the cathode of neighboring one. It also acts as a physical barrier to protect the air electrode material from the reducing environment of the fuel on the fuel electrode side, and it equally prevents the fuel electrode material from contacting with oxidizing atmosphere of the oxidant electrode side. A three-dimensional numerical model has been developed to evaluate the SOFC including the current collector, rectangular duct gas flow channels, gas diffusion electrodes and electrolyte layer. This model takes into account the hydrodynamic multi-component fluid flow and heat transfer analysis. Numerical results from the developed model using finite element method (COMSOLÂ®) show that the predicted polarization curve is in very good agreement with the published data. Simulations were also performed for different interconnect design cases obtained by varying electrode/interconnect contact area using finite volume method (FluentÂ®) to investigate the thermal and hydrodynamic behavior and finite element method (COMSOLÂ®) to investigate the electrical performance. The optimization is carried out by considering 25% interconnect contact area as the design criteria for maximum temperature gradient limitation. The best interconnect design with 60% interconnect contact area has been chosen which shows good thermal behavior with considerable power output among the different design cases. Simulations show a decreasing power density and reduction of temperature gradient for an increasing contact area. Parametric studies of the fuel cell for different mass flows, hydraulic diameters and interconnect material properties for optimized design have also been performed. Results reveal that the flow rate will have minor impact on the electrical performance compared to the effect of material properties. Strontium doped LaCrO 3 has shown better performance than calcium or magnesium doped LaCrO 3 . Decreasing the hydraulic diameter improves the mass transport situation along the length of the flow channel.

title: Analysis of flaked stone lithics from Virgin Anasazi sites near Mt. Trumbull, Arizona Strip
Creators: name: Martin, Cheryl Marie
Publisher: name: University of Nevada, Las Vegas
Year: 2009

description: This thesis examines flaked stone tools that were used by the Virgin Anasazi and the debitage resulting from their manufacture at six sites in the Mt. Trumbull region in order to infer past human behavior. The behaviors being examined include activities carried out at sites, the processing and use of raw stone materials, and patterns of regional exchange. I have applied obsidian sourcing technology and an analysis of flaked stone attributes. The research indicates a range of activities occurred at habitation sites at Mt. Trumbull, and toolmakers did not need to expend large amounts of time and energy on acquiring their lithic resources. Obsidian, although rare, was not so difficult to obtain or especially valued that it was highly conserved. The inhabitants of Mt. Trumbull obtained their obsidian through a dynamic system of interaction, but from different groups than those from which they acquired pottery, shell, and turquoise.

description: Saliency detection has been an intuitive way to provide useful cues for object detection and segmentation, as desired for many vision and graphics applications. In this paper, we provided a robust method for salient object detection and segmentation. Other than using various pixel-level contrast definitions, we exploited global image structures and proposed a new geodesic method dedicated for salient object detection. In the proposed approach, a new geodesic scheme, namely geodesic tunneling is proposed to tackle with textures and local chaotic structures. With our new geodesic approach, a geodesic saliency map is estimated in correspondence to spatial structures in an image. Experimental evaluation on a salient object benchmark dataset validated that our algorithm consistently outperformed a number of the state-of-art saliency methods, yielding higher precision and better recall rates. With the robust saliency estimation, we also present an unsupervised hierarchical salient object cut scheme simply using adaptive saliency thresholding, which attained the highest score in our F-measure test. We also applied our geodesic cut scheme to a number of image editing tasks as demonstrated in additional experiments.
