Analysis of Uncertainty in Procedural Maps in Slay the Spire
Creators: name: Bazzaz, Mahsa
name: Cooper, Seth
Publisher: name: arXiv
Year: 2025
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: This work investigates the role of uncertainty in Slay the Spire using an information-theoretic framework. Focusing on the entropy of game paths (which are based on procedurally-generated maps) we analyze how randomness influences player decision-making and success. By examining a dataset of 20,000 game runs, we quantify the entropy of paths taken by players and relate it with their outcomes and skill levels. The results show that victorious runs are associated with higher normalized entropy, suggesting more risk-taking. Additionally, higher-skill players tend to exhibit distinct patterns of risk-taking behavior in later game stages.

Essays on Information, Cognition and Consumption
Creators: Zorrilla, Oskar A.
Publisher: name: Columbia University
Year: 2019
Subjects: Economics
Consumption (Economics)
Decision making
Macroeconomics
Information behavior

description: This dissertation examines how agents process information and update their beliefs in two different contexts. In the first two chapters we consider dynamic decision problems under perfect information. In the last chapter we consider static, strategic interactions with common knowledge but imperfect information. To tackle our first set of questions we design an experiment analogous to the dynamic consumption problem with stochastic income that households solve in standard macroeconomic models. In the first chapter we show that our subjects condition on past actions in the absence of informational frictions or switching costs. We argue that subjects do so to economize on scarce cognitive resources and develop a model of inattentive reconsideration that fits our data. An implication of our model is that inertia is state- dependent. In the second chapter we revisit the longstanding problem in empirical macroeconomics of excess sensitivity of consumption to income in our experimental data. We find that excess sensitivity arises from two distinct channels. The first channel is an overreaction of households to the arrival of income that is independent of their wealth level. The second is increased excess smoothness with respect to wealth when households receive news about future income. The third chapter examines the scope for persuasion in global games. We consider a central bank with a commitment technology that chooses a robustly optimal persuasion strategy. We show that such a policy can reduce and even eliminate multiple equilibria in such games because it updates agents beliefs so that coordination motives become irrelevant. This suggests that central bankers are better served from influencing the markets through announcements rather than direct intervention.

description: Moore’s Law is running out. Instead of making powerful computer by increasing number of transistor now we are moving towardParallelism. Beowulf cluster means cluster of any Commodity hardware. Our Cluster works exactly similar to current day’ssupercomputers. The motivation is to create a small sized, cheap device on which students and researchers can get hands on experience.There is a master node, which interacts with user and all other nodes are slave nodes. Load is equally divided among all nodes and theysend their results to master. Master combines those results and show the final output to the user. For communication between nodes we havecreated a network over Ethernet. We are using MPI4py, which a Python based implantation of Message Passing Interface (MPI) andMPICH which also an open source implementation of MPI and allows us to code in C, C++ and Fortran. MPI is a standard for writing codesfor such clusters. We have written parallel programs of Monte Carlo’s Simulation for finding value of pi and prime number generator inPython and C++ making use of MPI4py and MPICH respectively. We have also written sequential programs applying same algorithms inPython. Then we compared the time it takes to run them on cluster in parallel and in sequential on a computer having 6500 core i7 Intelprocessor. It is found that making use of parallelism, we were able to outperform an expensive computer which costs much more than ourcluster.

description: Dynamic functional connectivity is an effective measure for the brain's responses to continuous stimuli. We propose an inferential method to detect the dynamic changes of brain networks based on time-varying graphical models. Whereas most existing methods focus on testing the existence of change points, the dynamics in the brain network offer more signals in many neuroscience studies. We propose a novel method to conduct hypothesis testing on changes in dynamic brain networks. We introduce a bootstrap statistic to approximate the supreme of the high-dimensional empirical processes over dynamically changing edges. Our simulations show that this framework can capture the change points with changed connectivity. Finally, we apply our method to a brain imaging dataset under a natural audio-video stimulus and illustrate that we are able to detect temporal changes in brain networks. The functions of the identified regions are consistent with specific emotional annotations, which are closely associated with changes inferred by our method.

description: A timely combination of new theoretical ideas and observational discoveries has brought about significant advances in our understanding of cosmic evolution. Computer simulations have played a key role in these developments by providing the means to interpret astronomical data in the context of physical and cosmological theory. In the current paradigm, our Universe has a flat geometry, is undergoing accelerated expansion and is gravitationaly dominated by elementary particles that make up cold dark matter. Within this framework, it is possible to simulate in a computer the emergence of galaxies and other structures from small quantum fluctuations imprinted during an epoch of inflationary expansion shortly after the Big Bang. The simulations must take into account the evolution of the dark matter as well as the gaseous processes involved in the formation of stars and other visible components. Although many unresolved questions remain, a coherent picture for the formation of cosmic structure in now beginning to emerge. In this paper, I review a selection of recent results obtained from simulations of the cosmic large-scale structure and galaxy formation and compare them with observational data, including results from the ``2dF Galaxy Redshift Survey.''

Publisher: name: Freie Universität Berlin
Year: 2013
Subjects: subject: 500 Naturwissenschaften und Mathematik::530 Physik

description: We calculate fluctuation corrections to the longitudinal conductivity of disordered superconductors subject to an external magnetic field. We derive analytic expressions that are valid in the entire metallic part of the temperature–magnetic field phase diagram as long as the effect of the magnetic field on the spin degrees of freedom of the electrons may be neglected. Our calculations are based on a kinetic equation approach. For the special case of superconducting films and wires in parallel magnetic fields, we perform a detailed comparison with results that were previously obtained with diagrammatic perturbation theory in the imaginary-time formalism. As an application, we study the fluctuation conductivity of films in tilted magnetic fields with a special focus on the low-temperature regime. We present a detailed discussion of the phenomenon of the nonmonotonic magnetoresistance and find that it displays a pronounced dependence on the tilting angle.

description: Elements of the quantization in field theory based on the covariant polymomentum Hamiltonian formalism (the De Donder-Weyl theory), a possibility of which was originally discussed in 1934 by Born and Weyl, are developed. The approach is based on a recently proposed graded Poisson bracket on differential forms in field theory (see e.g. hep-th/9709229). A covariant analogue of the Schrödinger equation for a hypercomplex wave function on the space of field and space-time variables is put forward. It is shown to lead to the De Donder-Weyl Hamilton-Jacobi equations in quasiclassical limit. A possible relation to the functional Schrödinger picture in quantum field theory is outlined.

Year: 2021

description: Misunderstanding of fundamental concepts is believed to be a major factor obstructing students from having a complete understanding of genetics. Similar misconceptions for the same basic concepts of genetics have been reported worldwide, and across all levels of education. This study combined information on the most common misconceptions in genetics in order to develop educational resources specifically designed to challenge university students’ misunderstanding of the key concepts. Three targeted educational resources were developed on the topics of meiosis, Mendelian inheritance, and the concept of the gene. The resources were designed using three different formats: video, card activity, and information booklet, respectively. The choice of media format was determined by the particular common misconceptions targeted. The resource development was conducted in a four stage action research approach of design, create, evaluate and reflect a modification of the traditional four stage approach of action research. The effectiveness of the resources in challenging students’ misconceptions was evaluated based on any subsequent students’ concept changes, how these resources had influenced these changes, and the students’ learning experiences. Two university student cohorts took part in this study, Biology Education students from Universitas Tanjungpur a in Indonesia and Biology and Biomedical undergraduate students from the University of Leicester in the United Kingdom. Research data were collected by means of tests observation and interview and were analysed and triangulated using qualitative approaches. The study showed that all three educational resources effectively promoted change s to students’ misconceptions. The effectiveness of the resources was dependent on their content presentation that challenged students’ misconceptions. The engagement of both Indonesia n and UK students was based on their perceived benefit of the resources rather than their enjoyment of the activity. This study also showed that it is possible to use a modified action research approach informed by published common misconceptions to create effective educational resources.

description: Parkinson’s disease (PD) is the second most common neurodegenerative disease, affecting over five million patients worldwide. Like Alzheimer’s disease (AD), it mostly affects the elderly and causes considerable disability and suffering. Unfortunately, the molecular mechanism of PD is still poorly understood, and there are no drugs available to treat the disease. Our overall aim was to identify natural products to probe PD by phenotypic assay using human olfactory neurosphere-derived (hONS) cells from PD patients. The research presented in this thesis exemplifies the importance of natural products as chemical probes for further investigation of PD as well as lead compounds for future PD-drug development. The thesis begins with an introduction of PD and the chemotherapeutics for PD. It also covers a review on the natural origin anti-PD compounds and the analysis of their physicochemical properties using Lipinski’s rule of five. As part of a research program aiming to identify anti-PD chemical probes, a high throughput screening assay was developed to screen 4224 fractions. Twenty fractions were confirmed to display neuroprotective effects of the PD cells against rotenone. Seven prioritized fractions, representing one Australian marine sponge Jaspis splendens (subject 1) and two Australian terrestrial plants Gloriosa superba (subject 2) and Alangium villosum (subject 3), were selected for large scale extraction and isolation. The results were presented in Chapter 2 to 5.

description: Nanomaterials have gained much attention for their use and benefit in several fields. Iron Oxide Nanoparticles (IONPs) have been used in Biomedicine as contrast agents for imaging cancer cells. However, several studies reported the potential toxicity of those nanoparticles in different models, especially in cells. Therefore, in our present study, we investigated the effects of IONPs on the SH-SY5Y neuroblastoma cell line. We carried out cytotoxic and genotoxic studies to evaluate the phenotypic effects, and proteomic investigation to evaluate the molecular effects and the mechanisms by which this kind of NPs could induce toxicity. Our results showed that the use of three different sizes of IONPs (14, 22 and 30 nm) induced cell detachment, cell morphological changes, size, and concentration-dependent IONP internalization and cell mortality. IONPs induced slight genotoxic damage assayed by modified comet assay without affecting cell cycle, mitochondrial function, membrane integrity, intracellular calcium level, and without inducing ROS generation. All the studies were performed to compare also the effects of IONPs to the ferric iron by incubating cells with equivalent concentration of FeCl3. In all tests, the NPs exhibited more toxicity than the ferric iron. The proteomic analysis followed by gene ontology and pathway analysis evidenced the effects of IONPs on cytoskeleton, cell apoptosis, and cancer development. Our findings provided more information about IONP effects on human cells and especially on cancer cell line.

description: Lie symmetry group theory is one of the most important methods in analysis of differential equations. Such Lie groups are invertible point transformations which result in the movement of dependent and independent variables of the differential equations. Constructing the solutions of nonlinear PDEs, mapping them to another solution by linear transformations, symmetry reductions and conservation laws are several principal applications of this theory.
Essays on Infrastructure and Development

Publisher: name: Columbia University

description: Spending on infrastructure accounts for several percentage points of global world product, reflecting its perceived importance to growth and development.  Previous literature has made limited progress in providing unbiased estimates of its impacts, or causal evidence about policy changes that can alter this impact.  Primarily, this is because of the selection problem: locations in which infrastructure is built differ from those in which it is not built.  This dissertation provides evidence towards three important questions related to infrastructure and development.  First, what role does manmade transport infrastructure play in determining and maintaining patterns of economic geography?  Second, to what degree does the relocation of economic activity in response to changes in the transport infrastructure network affect estimates of the economic impact of those changes?  Third, what is the effect of involving beneficiary communities in decision-making on projects to improve local infrastructure?  To address the selection problem, Chapters 2 and 3 exploit quasi-experimental variation in distance to a land transport route created by the opening and location of bridges over major rivers in the historical United States, using a new dataset containing every bridge built over the Mississippi and Ohio rivers.  Chapter 4 presents evidence from a randomized experiment in Bangladesh.

description: We investigate the tight monogamy and polygamy relations of multiparty entanglement for arbitrary quantum states. By using the power of the bipartite measure of entanglement, we establish a class of tight monogamy relations of multiparty entanglement with larger lower bounds than the existing monogamy relations. We also give a class of tight polygamy relations of multiparty entanglement with smaller upper bounds than the existing polygamy relations, by using the power of the entanglement of assistance. It is shown that these new monogamy and polygamy relations are tighter than the former results.

HYDRATE PLUGGING POTENTIAL IN UNDERINHIBITED SYSTEMS
Creators: name: Hemmingsen, Pål V.
name: Li, Xiaoyun
name: Kinnari, Keijo
Publisher: name: The University of British Columbia
Year: 2016

description: An underinhibited system is defined as a system where an insufficient amount of thermodynamic inhibitor is present to prevent hydrate formation. Underinhibition might occur due to malfunctioning of equipment, temporary limitations in the inhibitor supplies or operational limitations or errors. Understanding the plugging risk of such systems is important in order to take the correct precautions to avoid blocked flowlines. In this paper we summarize the experimental efforts for the last decade within StatoilHydro on the hydrate plugging risk in underinhibited systems. The flow simulator has been used as the main experimental equipment. The overall results for systems underinhibited with ethylene glycol or methanol show that the plugging potential increases up to a maximum at concentrations around 10-15 wt%. At higher concentrations the plugging potential reduces compared to the uninhibited system. The results can be explained as follows: As water is converted to hydrates in a system containing a thermodynamic inhibitor, the inhibitor concentration will increase until the remaining aqueous phase is inhibited. This self-inhibited aqueous phase will wet the hydrate particles, giving raise to the characteristic term of “sticky” hydrate particles. The aqueous layer surrounding the hydrate particles will form liquid bridges, by capillary attractive forces, upon contact with other hydrate particles or the pipe wall. During the hydrate formation period, there is also a possibility that some of the liquid bridges are converted to solid ones, strengthening the agglomerates. Depending on the oil-water interfacial tension, the phase ratio between the aqueous phase and the solid hydrates and the conversion of liquid bridges to solid ones, this leads to increased plugging risk at lower concentrations of inhibitor (< 20 wt%) and reduced risk at higher concentrations as compared to the uninhibited system.

description: Excitation of surface waves on conducting materials provides a near resistance-free interface capable of a material glissade either by plasmon forces or optical beam tractors. Analogous to an ice hockey rink, as proof of principle plasmon assisted optical traction, or hoovering, of water drops on a gold surface is demonstrated. Variability in thresholds and movement is observed and can be explained by the presence of significant roughness, measured by SEM. The demonstration opens a path to directly integrate various optical and plasmonic glissade technologies. Ways of improving transport and potential applications spanning configurable microfluidics, antennas, diagnostics,sensing and active devices are discussed.

Under the ridge covering mode, the main distribution area of the underground roots of Jinhong apple trees was moved down to 15-55 cm, the temperature of soil 20 cm beneath the surface of the ridges increased by 1.3-1.5℃, the temperature of soil 40 cm beneath the surface of the ridges rose by 0.9-1.0℃, and the water content of soil 20-40 cm from the ground was maintained around 5%. Under the ridge covering mode, the Jinhong apple trees grew robustly, began to fruit 3 years later and yielded highly 5 years later. In addition, the ridge covering model also has illumination-enhancing, pest-controlling and tillage-free characteristics.

description: This dissertation focuses on the economics of infrastructure development and public finance. The dissertation is composed of three papers: The first paper analyzes the optimal solutions for supplying electricity to national economies from both domestic as well as distant energy resources using transmission systems that can connect the huge renewable energy resources of Africa. The results point to options for achieving substantial increases in the sustainable energy supply and for improving access to energy across the continent. The second paper models a comparative local and national electricity distribution planning in Senegal by examining the trade-off between access and costs. The third paper uses exogenous variations in rainfall across municipalities in Mali to estimate the causal effect of household income shocks on municipal-level tax revenues. It also exploits a national tax collection incentive policy to measure the impacts of rainfall variation on intergovernmental transfers.

description: The inhibitor and steam injection methods have been examined using a laboratory-prepared methane hydrate bearing sediment. New experimental apparatuses have been designed and constructed. In the case of inhibitor injection, the measurement of gas production vs. time suggested that the inhibitor increased dissociation rate. Core temperature decreased upon the inhibitor injection, in contrast to that in the case of pure water injection. The observed pressure differentials between the inlet and outlet of the core sample suggest that the inhibitor effectively prevented the hydrate reformation within the dissociating core sample. In the case of steam injection coupled with depressurization, it can be seen that the effect of steam (or hot water) injection was clear in the later stage of dissociation, compared with that in the case of depressurization alone. The inner (core) temperature change indicates that the coupling of depressurization and steam injection induces MH dissociation from upstream and downstream to the center of the sample. However, it starts from an upstream region and continues downstream steadily in the case of steam (hot water) injection alone.

description: Intrinsic alignments of galaxies can mimic to an extent the effects of shear caused by weak gravitational lensing. Previous studies have shown that for shallow surveys with median redshifts z_m = 0.1, the intrinsic alignment dominates the lensing signal. For deep surveys with z_m = 1, intrinsic alignments are believed to be a significant contaminant of the lensing signal, preventing high-precision measurements of the matter power spectrum. In this paper we show how distance information, either spectroscopic or photometric redshifts, can be used to down-weight nearby pairs in an optimised way, to reduce the errors in the shear signal arising from intrinsic alignments. Provided a conservatively large intrinsic alignment is assumed, the optimised weights will essentially remove all traces of contamination. For the Sloan spectroscopic galaxy sample, residual shot noise continues to render it unsuitable for weak lensing studies. However, a dramatic improvement for the slightly deeper Sloan photometric survey is found, whereby the intrinsic contribution, at angular scales greater than 1 arcminute, is reduced from about 80 times the lensing signal to a 10% effect. For deeper surveys such as the COMBO-17 survey with z_m = 0.6, the optimisation reduces the error from a largely systematic 220% error at small angular scales to a much smaller and largely statistical error of only 17% of the expected lensing signal. We therefore propose that future weak lensing surveys be accompanied by the acquisition of photometric redshifts, in order to remove fully the unknown intrinsic alignment errors from weak lensing detections.

description: We present the construction of the ground state of the Gross-Pitaevskii-Poisson equations using genetic algorithms. By employing numerical solutions, we develop an empirical formula for the density that works within the considered parameter space. Through the analysis of both numerical and empirical solutions, we investigate the stability of these ground state solutions. Our findings reveal that while the numerical solution outperforms the empirical formula, both solutions lead to similar oscillation modes. We observe that the stability of the solutions depends on specific values of the central density and the nonlinear self-interaction term, and establish an empirical criterion delineating the conditions under which the solutions exhibit stability or instability.

description: Using supersymmetric quantum mechanics we develop a new method for constructing quasi-exactly solvable (QES) potentials with two known eigenstates. This method is extended for constructing conditionally-exactly solvable potentials (CES). The considered QES potentials at certain values of parameters become exactly solvable and can be treated as CES ones.

description: In this paper, we study three-dimensional Kudryashov-Sinelshchikov (K-S) equation, which describes long nonlinear pressure waves in a liquid containing gas bubbles. Firstly, We find the symmetry groups of the K-S equation. Secondly, using the symmetry groups, exact solutions which are invariant under a threedimensional subalgebra of the symmetry Lie algebra are derived. Finally, by adding Bluman-Anco homotopy formula to the direct method local conservation laws of the K-S equation are obtained.

description: As an important platform for the combination of theory and practice, college students' innovative and entrepreneurial training program has an important impact on improving the comprehensive ability of undergraduates. The major of aquatic animal medicine is a new sea-related major. The continuous development and transformation and upgrading of aquaculture in the new period have put forward newer and higher requirements for the innovative and practical ability and comprehensive quality of aquatic animal medicine graduates. Taking the innovation and entrepreneurship program of college students majoring in aquatic animal medicine as an example, this paper analyzes the significance of the innovation training program for college students, the cultivation of students' scientific research ability, and the problems existing in the application and operation of the program, in order to provide a reference for the innovative education and talent training for students majoring in aquatic animal medicine.
Criteria to detect genuine multipartite entanglement using spin measurements

Year: 2019
Subjects: subject: Quantum Physics (quant-ph)

description: We derive conditions in the form of inequalities to detect the genuine $N$-partite entanglement of $N$ systems. The inequalities are expressed in terms of variances of spin operators, and can be tested by local spin measurements performed on the individual systems. Violation of the inequalities is sufficient (but not necessary) to certify the multipartite entanglement, and occurs when a type of spin squeezing is created. The inequalities are similar to those derived for continuous-variable systems, but instead are based on the Heisenberg spin-uncertainty relation $ΔJ_{x}ΔJ_{y}\geq|\langle J_{z}\rangle|/2$. We also extend previous work to derive spin-variance inequalities that certify the full tripartite inseparability or genuine multi-partite entanglement among systems with fixed spin $J$, as in Greenberger-Horne-Zeilinger (GHZ) states and W states where $J=1/2$. These inequalities are derived from the planar spin-uncertainty relation $(ΔJ_{x})^{2}+(ΔJ_{y})^{2}\geq C_{J}$ where $C_{J}$ is a constant for each $J$. Finally, it is shown how the inequalities detect multipartite entanglement based on Stokes operators. We illustrate with experiments that create entanglement shared among separated atomic ensembles, polarization-entangled optical modes, and the clouds of atoms of an expanding spin-squeezed Bose-Einstein condensate. For each example, we give a criterion to certify the mutual entanglement.

description: This research project will examine whether the cultural training that news editors receive in their organisations affects their international news selection, and whether this ultimately affects international news reportage in Australia. The study is based on previous research focusing on three main areas of scholarship, drawn from a wider range of international theatres. These three bodies of work focus on: (1) factors affecting the selection, construction and presentation of international news; (2) how news editors and news directors function as gatekeepers of international news within newsrooms, and how they prioritise international news; and (3) whether cultural training occurs in Australian newsrooms, and if so, how it influences the gatekeeper’s news selection process, and through it, world news coverage in the Australian news media. This study partially replicated research completed by Australian media scholar Peter Putnis in 1996 (Putnis 1996), and extended it to three Brisbane news bulletins: a commercial television bulletin, a public radio news bulletin, and a commercial online portal. The data obtained from the news bulletins were gathered during a constructed week to analyse whether the selection and framing around the presentation of international news in Australia had changed since Putnis’ seminal work. In addition to the aforementioned qualitative analysis of media content, a number of news editors and media experts across Australia were interviewed to determine their self-perception of gatekeeping responsibilities; and assess their degree of agency as gatekeepers in conjunction with institutional news priorities and directions. Within this framework, the gatekeepers were asked how important cultural training was for them and how they believed such training changed the reporting outcomes. These interviews were then used to develop a radio documentary that was broadcast on the national community radio network. Using these interviews as both data for qualitative research and source content for a media production demonstrates how such information-gathering methodologies are shared and used in both journalism studies research and journalism production. The argument proposed in this study is that international news is not prioritised in Australian journalism; and that a lack of world news coverage persists because Australian news editors believe international news is not important to their audiences —even though Australia is a multicultural country. It then argues, based on interviews with news editors and news directors, that cultural training is needed to create awareness about events happening outside Australia. These research aims are demonstrated through both the series of radio documentaries, and the exegetical component of this work.

description: Il 13 maggio 2020, l’allora Ministra dell’Agricoltura Teresa Bellanova, nel corso della conferenza stampa volta ad illustrare i contenuti del cosiddetto “Decreto Rilancio”, annunciava un provvedimento di regolarizzazione rivolto ai lavoratori stranieri, il primo da otto anni. La sanatoria era una misura fortemente attesa, tanto dai cittadini/e stranieri/e, che dai datori e dalle datrici di lavoro, così come dalle organizzazioni della società civile impegnate nel campo dei diritti dei migranti. Già dalle prime letture sono però emersi numerosi rilievi critici sulla prevista efficacia del provvedimento con riferimento alle finalità dichiarate, che oggi si ripropongono con rinnovata urgenza.
