description: We study the superradiant emission of an inverted spin ensemble strongly coupled to a superconducting cavity. After fast inversion, we detune the spins from the cavity and store the inversion for tens of milliseconds, during which the remaining transverse spin components disappear. Switching back on resonance enables us to study the onset of superradiance. A weak trigger pulse of a few hundred photons shifts the superradiant burst to earlier times and imprints its phase onto the emitted radiation. For long hold times, the inversion decreases below the threshold for spontaneous superradiance. There, the energy stored in the ensemble can be used to amplify microwave pulses passing through the cavity.

description: We examine the X-ray spectra of VII Zw 403, a nearby low-metallicity blue compact dwarf (BCD) galaxy. The galaxy has been observed to contain an X-ray source, likely a high mass X-ray binary (HMXB), with a luminosity of 1.3-23x10^38 erg s^-1 in the 0.3-8 keV energy range. A new Suzaku observation shows a transition to a luminosity of 1.7x10^40 erg s^-1 [0.3-8 keV], higher by a factor of 7-130. The spectra from the high flux state are hard, best described by a disk plus Comptonization model, and exhibit curvature at energies above 5 keV. This is consistent with many high-quality ultraluminous X-ray source spectra which have been interpreted as stellar mass black holes (StMBH) accreting at super-Eddington rates. However, this lies in contrast to another HMXB in a low-metallicity BCD, I Zw 18, that exhibits a soft spectrum at high flux, similar to Galactic black hole binaries and has been interpreted as a possible intermediate mass black hole. Determining the spectral properties of HMXBs in BCDs has important implications for models of the Epoch of Reionization. It is thought that the main component of X-ray heating in the early universe was dominated by HMXBs within the first galaxies. Early galaxies were small, metal-deficient, star forming galaxies with large H I mass fractions --- properties shared by local BCDs we see today. Understanding the spectral evolution of HMXBs in early universe analogue galaxies, such as BCDs, is an important step in estimating their contribution to the heating of the intergalactic medium during the Epoch of Reionization. The strong contrast between the properties of the only two spectroscopically studied HMXBs within BCDs motivates further study on larger samples of HMXBs in low metallicity environments in order to properly estimate the X-ray heating in the early universe.

description: Urban affordable housing planning and development is a challenging enterprise. Practitioners, which range from small neighborhood community development corporations to county-level agencies to nonprofit developers operating at the regional level, routinely solve problems involving multiple stakeholders, competing objectives, funding sources, production processes, strategies and outcome measures. Academic research addressing the design and evaluation of policies that address community concerns and generate significant social impacts is limited.

Using surveys and in-depth interviews with affordable housing providers in the Pittsburgh metropolitan area, we describe current practices and organizational values and test hypotheses that address the relationships between organizational characteristics, neighborhood characteristics and residential real estate development choices and methods. These findings are used to formulate quantitative planning models that address two problems faced by providers: choice of parcels to develop in order to maximize the social benefit associated with low-income housing search, and choice of parcels to develop to maximize neighborhood-level benefits.
We find substantial support for structured, prescriptive policy modeling that is evidence-based, value-focused and methodologically appropriate.

description: Public-sector policy design is inherently complex: there are multiple stakeholders, multiple objectives, and ambiguous or unknown evidence regarding effective policy interventions. One response to this problem is the design of decision support systems (DSS) to help ordinary citizens as well as policymakers make choices that enrich their daily lives and participate in policy and planning processes. DSS typically combine information technology tools for data storage, analysis, and visualization with decision models that help users formulate and solve problems that might otherwise appear impossible to formulate clearly or are computationally intractable. This paper proposes a framework for developing DSS for public sector policy making that reflects a number of key principles. First, DSS should be values-based—reflective of ethical and moral considerations that motivate users to address problems of public interest. Second, it should be evidence-based—containing data and functional relationships that represent best knowledge and practices. Third, it should be model-based—containing representations of real-world systems that generate actionable recommendations based on multiple choice alternatives. Last, it should facilitate creativity and negotiation—enabling multiple stakeholders to collaborate and explore “what-if” questions easily and identify “best-compromise” solutions quickly. Evidence to support this theory of public DSS comes from current projects on increasing citizen participation in initiatives to reduce energy use, policy design for senior services provision, and choosing new neighborhoods for use of tenant-based housing subsidies.

description: Behavioral scientists have classically documented aversion to algorithmic decision aids, from simple linear models to AI. Sentiment, however, is changing and possibly accelerating AI helper usage. AI assistance is, arguably, most valuable when humans must make complex choices. We argue that classic experimental methods used to study heuristics and biases are insufficient for studying complex choices made with AI helpers. We adapted an experimental paradigm designed for studying complex choices in such contexts. We show that framing and anchoring effects impact how people work with an AI helper and are predictive of choice outcomes. The evidence suggests that some participants, particularly those in a loss frame, put too much faith in the AI helper and experienced worse choice outcomes by doing so. The paradigm also generates computational modeling-friendly data allowing future studies of human-AI decision making.

description: Advanced ceramic materials, known for their unique thermal and mechanical properties, are increasingly utilized in high-performance applications, including heat exchangers, filtration systems, and chemical reactors. Understanding the flow resistance characteristics of these materials is critical for optimizing their use in industrial systems. This paper focuses on the determination of flow resistance coefficients for various types of advanced ceramics using both experimental and theoretical methods. By analyzing flow behavior through porous structures, we provide insights into the relationship between porosity, material composition, and flow resistance, which are essential for designing efficient industrial processes. The results indicate that material porosity and surface roughness significantly influence the flow resistance coefficient, offering a guide for material selection and system optimization.

description: In a recent paper, Robert Putnam presents findings that racial and ethnic diversity erodes trust among neighbors. Given trends in global immigration, coupled with the centrality of trust to social capital, these findings are par ticularly disturbing. However, there may be reason to believe that Putnamfis new findings are a false alarm; that individuals and families base their choice of residence in part on the racial and ethnic composition of cities and neigh borhoods. If this is the case, then many agents will naturally prefer to live near members of their own race - a group with which they are likely to have a high level of trust. While such endogenous sorting into racially homogeneous neighborhoods may affect the formation of social capital, it does not imply that the objectives of diversity and social capital are mutually exclusive. This paper presents evidence that this type of sorting does indeed oc cur, creating the appearance of a negative effect of diversity on trust between neighbors. Before presenting this evidence, this paper gives a brief overview of the the oretical impacts of social capital formation, discuss the mutual relationships between diversity, racial attitudes and social capital, and present an anal ysis of the relationship between social capital, diversity and the residential location decisions of families and individuals.

description: Current watershed-scale, nonpoint source (NPS) pollution models do not represent the processes and impacts of agricultural best management practices (BMP) on water quality with sufficient detail. To begin addressing this gap, a novel process-based, watershed-scale, water quality model (WEPP-WQ) was developed based on the Water Erosion Prediction Project (WEPP) and the Soil and Water Assessment Tool (SWAT) models. The proposed model was validated at both hillslope and watershed scales for runoff, sediment, and both soluble and particulate forms of nitrogen and phosphorus. WEPP-WQ is now one of only two models which simulates BMP impacts on water quality in ‘high’ detail, and it is the only one not based on USLE sediment predictions. Model validations indicated that particulate nutrient predictions were better than soluble nutrient predictions for both nitrogen and phosphorus. Predictions of uniform conditions outperformed nonuniform conditions, and calibrated model simulations performed better than uncalibrated model simulations. Applications of these kinds of models in real-world, historical simulations are often limited by a lack of field-scale agricultural management inputs. Therefore, a prototype tool was developed to derive management inputs for hydrologic models from remotely sensed imagery at field-scale resolution. At present, only predictions of crop, cover crop, and tillage practice inference are supported and were validated at annual and average annual time intervals based on data availability for the various management endpoints. Extraction model training and validation were substantially limited by relatively small field areas in the observed management dataset. Both of these efforts contribute to computational modeling research and applications pertaining to agricultural systems and their impacts on the environment.

description: Healthcare is primarily delivered in the ambulatory care setting. The high variability in service delivery encountered in this environment negatively impacts efficiency, quality of care, costs, patient satisfaction and safety. Care coordination, a process to manage dependencies between clinicians who provide care to a patient, has been proposed as a critical and challenging step in improving care delivery and health outcomes. In this study, we develop optimal care coordination models and policies for the ambulatory care delivery environment that optimize important service delivery metrics using a novel data collection strategy that employs RFID technology. Time and location stamped data is collected using RTLS-based Gen2IR/RFID-enabled badges worn by patients, clinicians, and staff as they complete each clinic visit. This data is mapped to facility and personnel resources and specific tasks associated with each visit to track patient flow. We analyze process variability using discrete event simulation and sequential pattern analysis, and formulate a Markov decision process model to identify best practice plans that improve care coordination. 389 office visit records associated with 327 unique patients and 12 clinicians and staff, collected over a 2-month period, are used to instantiate our models and identify optimal policies. The results also highlight the value of RTLS solutions and the challenges in deploying them to understand variability in patient care and opportunities to re-engineer services to improve service delivery in the ambulatory care environment. These methods and approaches are generalizeable to other care delivery settings and have the potential to improve healthcare services significantly.

description: An implicit expectation of asking users to rate agents, such as an AI decision-aid, is that they will use only relevant information -- ask them about an agent's benevolence, and they should consider whether or not it was kind. Behavioral science, however, suggests that people sometimes use irrelevant information. We identify an instance of this phenomenon, where users who experience better outcomes in a human-agent interaction systematically rated the agent as having better abilities, being more benevolent, and exhibiting greater integrity in a post hoc assessment than users who experienced worse outcome -- which were the result of their own behavior -- with the same agent. Our analyses suggest the need for augmentation of models so that they account for such biased perceptions as well as mechanisms so that agents can detect and even actively work to correct this and similar biases of users.

title: Beam profile measurements using the straw tracking detectors at the Fermilab muon g − 2 experiment, and a study of their sensitivity to a muon electric dipole moment
Creators: name: Charity, S
Publisher: name: University of Liverpool Repository
Year: 2019

description: The Fermilab muon g-2 experiment aims to measure the anomalous magnetic dipole moment of the muon, aμ , to a precision of 140 ppb. The current value of aμ was measured at the Brookhaven g − 2 experiment, whose final result was published in 2006 with an uncertainty of 0.54 ppm [1]. The deviated from the Standard Model (SM) prediction by up to 3.6 σ, causing international intrigue that motivated the repetition of the experiment with increased statistics. The experiment’s storage ring (SR) magnet was transported to Fermilab in 2013 to make use of its high-intensity muon beam. This will facilitate a 21-fold increase in statistics that will contribute most of the improved precision in the aμ measurement. In addition, improvements to the experimental hardware are intended to reduce the systematic uncertainty. A major improvement is a new straw tracking detector system, which will measure the beam profile continuously throughout the experiment, in order to mitigate sources of systematic error associated with the beam position and motion. The straw trackers will also be used to perform a muon electric dipole moment (EDM) search. The current world’s best limit on the muon EDM was placed by the Brookhaven g − 2 experiment [2]. The signal for a muon EDM in the g − 2 experiment can be directly measured with the straw tracking detectors, so the upgraded tracking system is expected to enable a reduction in the current limit by a factor of 100. This thesis will describe the design and construction of the straw tracking detectors that took place at the University of Liverpool. The development and optimisation of a track extrapolation algorithm for propagating the track parameters of the decay positrons back to the muon decay position will be presented. The use of this algorithm in measuring the beam profile during the commissioning phase of the experiment will be discussed, and finally, the development of a muon EDM simulation and a preliminary sensitivity study using the track extrapolation algorithm will be presented.

A Quantum Monte Carlo study of the structural, energetic, and magnetic properties of two-dimensional (2D) H and T phase VSe$_2$

description: Previous works have controversially claimed near-room temperature ferromagnetism in two-dimensional (2D) VSe$_2$, with conflicting results throughout the literature. These discrepancies in magnetic properties between both phases (T and H phase) of 2D VSe$_2$ are most likely due to the structural parameters being coupled to the magnetic properties. Specifically, both phases have a close lattice match and similar total energies, which makes it difficult to determine which phase is being observed experimentally. In this study, we used a combination of density functional theory (DFT), highly accurate diffusion Monte Carlo (DMC) and a surrogate Hessian line-search optimization technique to resolve the previously reported discrepancy in structural parameters and relative phase stability. With DMC accuracy, we determined the freestanding geometry of both phases and constructed a phase diagram. Our findings demonstrate the successes of the DMC method coupled with the surrogate Hessian structural optimization technique when applied to a 2D magnetic system.
Spatio-Temporal Forecasting of Crime: Application of Classical and Neural Network Methods

description: This paper introduces a new spatio-temporal forecasting methodology that combines artificial neural networks and cellular automata with GIS-based data. The technique, which we refer to as chaotic cellular forecasting (CCF) is similar to spatial adaptive filtering due to Foster and Gorr (1986) and weighted spatial adaptive filtering due to Gorr and Olligschlaeger (1994) in that it uses contiguity relationships and the geographer’s assumption that influence between data points decays with distance. As with spatial adaptive filtering the methodology uses an iterative process to arrive at a solution. Unlike spatial adaptive filtering, however, chaotic forecasting uses a gradient descent method rather than a grid search to find the optimal set of parameters (or, in the case of artificial neural networks, weights). In addition, and most importantly, CCF has the nonlinear and multi-model functional form commonly used in neural net modeling, allowing for increased pattern recognition and accommodation of spatio-temporal heterogeneity. The result is a robust spatio-temporal forecasting method that requires very little model specification, is self - adaptive and performs very well on data sets that exhibit non-traditional statistical behavior.

description: We perform an exhaustive follow-up analysis of a subsolar-mass (SSM) gravitational wave (GW) candidate reported by Phukon et al. from the second observing run of Advanced LIGO. This candidate has a reported signal-to-noise ratio (SNR) of $8.6$ and false alarm rate of $0.41$ yr which are too low to claim a clear gravitational-wave origin. When improving on the search by using more accurate waveforms, extending the frequency range from 45 Hz down to 20 Hz, and removing a prominent blip glitch, we find that the posterior distribution of the network SNR lies mostly below the search value, with the $90\%$ confidence interval being $7.94^{+0.70}_{-1.05}$. Assuming that the origin of the signal is a compact binary coalescence (CBC), the secondary component is $m_2 = \text{$0.76^{+0.50}_{-0.14}$} M_\odot$, with $m_2 < 1 M_\odot$ at $84\%$ confidence level, suggesting an unexpectedly light neutron star or a black hole of primordial or exotic origin. The primary mass would be $m_1 = \text{$4.71^{+1.57}_{-2.18}$} M_\odot$, likely in the hypothesized lower mass gap and the luminosity distance is measured to be $D_{\rm L}=124^{+82}_{-48}$Mpc. We then probe the CBC origin hypothesis by performing the signal coherence tests, obtaining a log Bayes factor of $4.96 \pm 0.13$ for the coherent vs. incoherent hypothesis. We demonstrate the capability of performing a parameter estimation follow-up on real data for an SSM candidate with moderate SNR. The improved sensitivity of O4 and subsequent LIGO-Virgo-KAGRA observing runs could make it possible to observe similar signals, if present, with a higher SNR and a more precise measurement of the parameters of the binary.

These trajectories are studied here for relativistic spin-one-half particles.Based in explicit numerical calculations for the case of a massless particle in dimension three space-time, it is shown that if the wave function is an eigenfunction of the total angular momentum, the trajectories begin as circles of slowly increasing radius until a transition time at which they tend to follow straight lines. Arrival times at some detector, as well as their probability distribution are calculated, too. The chosen energy and momentum parameters are of the orders of magnitude met in graphene's physics.

description: The self-assembly of anisotropic patchy particles with triangular shape was studied by experiments and computer simulations. The colloidal particles were synthesized in a two-step seeded emulsion polymerization process, and consist of a central smooth lobe connected to two rough lobes at an angle of $\sim$90$^{\circ}$, resembling the shape of a "Mickey Mouse" head. Due to the difference in overlap volume, adding an appropriate depletant induces an attractive interaction between the smooth lobes of the colloids only, while the two rough lobes act as steric constraints. The essentially planar geometry of the "Mickey Mouse" particles is a first geometric deviation of dumbbell shaped patchy particles. This new geometry is expected to form one-dimensional tube-like structures rather than spherical, essentially zero-dimensional micelles. At sufficiently strong attractions, we indeed find tube-like structures with the sticky lobes at the core and the non-sticky lobes pointing out as steric constraints that limit the growth to one direction, providing the tubes with a well-defined diameter but variable length both in experiments and simulations. In the simulations, we found that the internal structure of the tubular fragments could either be straight or twisted into so-called Bernal spirals.
The Law of One Price? The Impact of IT-Enabled Markets on Consumer Search and Retailer Pricing

description: Recent IT research has analyzed how the performance of IT-enabled markets may differ from
conventional markets. This literature has made two unexpected empirical findings. First, ITenabled
markets for commodity goods exhibit significant price dispersion. Second, well-known
retailers in these markets appear to cooperate to set high prices.

This paper presents an analytic model, and confirmatory empirical evidence, that explains this
behavior as a response to the unique characteristics of consumer search in electronic markets. In
conventional markets, consumer search costs are primarily a function of the consumer’s physical
proximity to retailer outlets — and physical proximity is distributed relatively equally across
retailers. In electronic markets, consumer search costs are primarily a function of the consumer’s
mental awareness of different retailers — and this awareness is likely to be concentrated in the
hands of a few retailers.

Based on this model of consumer search, IT-enabled markets for commodity goods exhibit high
price dispersion in equilibrium and a few well-known retailers are able to cooperate to set high
prices. The predictions of the model are shown to be consistent with empirical data for 23,744
books collected from 24 Internet retailers in late 1999. Viewing consumer search in this manner
provides a useful starting point for understanding the likely development of IT-enabled markets,
and for understanding the importance of advertising and first-mover advantage for electronic
market participants.

Platooning which is defined as controlling a group of autonomous vehicles (multiple followers and one leader) to have a desired distance between them while following a desired trajectory has caught on recently in the control engineering discipline. Platooning brings along promising advantages, namely, increasing highway capacity and safety, and reducing fuel consumption. In this paper, using linearized longitudinal dynamic models for each vehicle, we investigate the control problem of vehicular platooning to have all vehicles followed the leader under a constant spacing policy. Under decentralized linear feedback controllers and taking account of heterogeneity in the dynamic models and feedback information to the vehicles, a general dynamic representation for the platoon is obtained. Having this and the proposed controller, stability analysis is developed for any information flow topology (IFT) between vehicles and any number of vehicles. As a case study, a platoon with one leader and two followers is investigated through the proposed strategy, and its stability conditions are provided. Numerical simulations are provided in which the stability range of control gains and the effect of different IFTs on the performance of the platoon are discussed.

description: Diagnostic information helps agents to make more accurate decisions. One such decision
is about investing in projects with uncertain outcomes. The value of diagnostic
information is the difference in expected payoffs with and without it, and we show that
such a value is non-monotonic in the ex-ante expected value of the project to be
undertaken. We analyze optimal pricing schemes for selling information to buyers with
unknown ex ante value. With a monopolist information seller, a striking result is that the
optimal menu of contracts is remarkably simple. A pure royalty is offered to buyers
whose projects have low ex-ante expected value and a pure fixed fee is offered to buyers
whose projects have high ex-ante expected value. This result is robust to the presence of
different types of information and to the introduction of competition in the market for
diagnostic information.

description: The XGain project develops a Knowledge Facilitation Tool (KFT) to help rural stakeholders select ICT infrastructures for digital services. One focus is on a Catalonian use case, exploring a drone center for agriculture. The drone service setup uses a private 5G network and edge computing to support real-time video transmission and processing, which are key for drone services.

title: Inverse Vulcanised Sulfur Polymers for Heavy Metal Remediation
Creators: name: Parker, Douglas
Publisher: name: University of Liverpool Repository
Year: 2020

description: This thesis describes the work undertaken between two interlinked fields of chemical research; the synthesis of novel sustainable inverse vulcanised sulfur polymers and their applications for the remediation of heavy metals. Chapter 1 includes an introduction to sulfur and its chemistry, inverse vulcanisation and its processes and a discussion of previously reported work in the field. The potential applications for inverse vulcanised sulfur polymers and background information relating to heavy metals, their toxicity and environmental contamination are also contained in this chapter. Research into new crosslinkers and the route to establishing an adaptable synthetic method suitable for the inverse vulcanisation of multiple different sustainable crosslinking agents is presented in Chapters 2 and 3. These chapters cover early initial reactions, background information on potential new crosslinkers and the synthesis and analysis of nine new polymeric materials. Chapter 4 discusses the potential application for these polymers as sorbents for heavy metal remediation. This chapter discusses routes to enhancing the surface area of these novel polymeric materials, followed by the results from in situ testing of these materials against a range of inorganic and organometallic heavy metal compounds. Detailed experimental methods and heavy metal testing protocols, information relating to the instrumentation used to generate the data presented in this thesis and the relevant analytical theory behind these techniques, is to be found in Chapter 5. Chapter 6 covers the main conclusions drawn from this research and suggests how this project could be continued in the future.
Standards Competition in the Presence of Digital Conversion Technology: An Empirical Analysis of the Flash Memory Card Market

description: Theoretical and empirical evidence suggest that in many markets with standards competition, network
effects make the strong grow stronger and can “tip” the market toward a single, winner-take-all standard.
We hypothesize, however, that this sort of standards-induced market dominance may be less common in
the context of digital systems, where the presence of low cost conversion technologies may facilitate easy
compatibility across competing standards. We empirically test our hypotheses in the context of the digital
flash memory card market.

We first test for the presence of network effects in this market, and find that network effects strongly
influence competition between flash memory standards. We then analyze whether these network effects
are moderated by the adoption of digital converters, and find that the availability of digital converters
provides a measurable reduction in the price premium of the leading flash card formats relative to that of
formats with lower market shares. These market dynamics imply that producers of non-dominant digital
goods standards are better off with the provision of conversion technology, as this technology tends to
neutralize the impact of network effects. In addition, further analysis shows that market concentration in
the flash memory market decreases as converters become more widely available.
Galaxy Zoo: the dependence of the star formation-stellar mass relation on spiral disk morphology

description: We measure the stellar mass-star formation rate relation in star-forming disk galaxies at z<0.085, using Galaxy~Zoo morphologies to examine different populations of spirals as classified by their kiloparsec-scale structure. We examine the number of spiral arms, their relative pitch angle, and the presence of a galactic bar in the disk, and show that both the slope and dispersion of the M-SFR relation is constant when varying all the above parameters. We also show that mergers (both major and minor), which represent the strongest conditions for increases in star formation at a constant mass, only boost the SFR above the main relation by ~0.3 dex; this is significantly smaller than the increase seen in merging systems at z>1. Of the galaxies lying significantly above the M-SFR relation in the local Universe, more than 50% are mergers. We interpret this as evidence that the spiral arms, which are imperfect reflections of the galaxy's current gravitational potential, are either fully independent of the various quenching mechanisms or are completely overwhelmed by the combination of outflows and feedback. The arrangement of the star formation can be changed, but the system as a whole regulates itself even in the presence of strong dynamical forcing.

Testing for Discrimination: Evidence from the Game Show Street Smarts

description: This paper conducts two alternative tests of discrimination in the game show Street Smarts, which both exploit the unique setup of the game to determine why discrimination occurs. The results indicate non-black contestants have a lower prior perception of the skill level of blacks relative to non-blacks in answering the average question in the game. When results are stratified by question category, one finds that non-black contestants perceive blacks and non-blacks to have equal ability in answering general knowledge questions. However, they perceive blacks to have a lower ability in answering miscellaneous, entertainment, and slang/common saying questions.
Vieira e a possibilidade de um Mundo Novo: percursos, projectos, utopias, sucessos e fracassos de um pregador barroco
Creators: name: Abreu, Luís Machado De
Publisher: name: Revista Lusófona de Ciência das Religiões
Year: 2013

description: Esboça-se, neste pequeno ensaio, o perfil do Padre António Vieira, seleccionando e carregando alguns traços da sua fisionomia histórica e cultural. Como marcas dominantes realçam-se as seguintes: jesuíta, pregador e mestre da língua, diplomata da Restauração, amigo de judeus e cristãos novos, missionário e defensor dos índios, profeta do Quinto Império, vítima do Santo Ofício. Em qualquer destes aspectos, a memória de Vieira é a rememoração de um excesso de ousadia e grandeza, que continua a desafiar as normalidades do tempo secularizado em que lhe sobrevivemos.

O Regresso do Religioso – afirmação, crítica, subversão e profecia
Creators: name: Pinto, Henrique
Publisher: name: Revista Lusófona de Ciência das Religiões
Year: 2013

description: Em sintonia com o espírito do sapere aude kantiano (ouse ou atreva-se a saber), mas tendo em Nietzsche e Heidegger a ausência de um centro absoluto ou o lieu vide que o iluminismo foi incapaz de domesticar, reconhecer e incarnar, este breve texto procura explicar o regresso do religioso, o seu significado e algumas das suas mais imediatas implicações políticas, sócio-económicas e teológicas, depois que este começou a ser debatido há cerca de duas décadas em Capri (Itália), e com uma constante referência ao pensamento de Michel Foucault, Jacques Derrida, e a alguns dos seus mais importante intérpretes, nestas áreas, como John D. Caputo, Jeremy Carrette e outros. Sem poder negar ou afirmar a possibilidade de Deus, o artigo sugere uma nova forma de conceber e de corporizar uma relação pós-moderna entre o humano e o divino, livre de qualquer dualismo, e manifesta numa constante afirmação e subversão de nós mesmos, pela prática do diálogo livre e aberto com o tout autre em cada rosto.

Wick polynomials and time-evolution of cumulants

description: We show how Wick polynomials of random variables can be defined combinatorially as the unique choice which removes all "internal contractions" from the related cumulant expansions, also in a non-Gaussian case. We discuss how an expansion in terms of the Wick polynomials can be used for derivation of a hierarchy of equations for the time-evolution of cumulants. These methods are then applied to simplify the formal derivation of the Boltzmann-Peierls equation in the kinetic scaling limit of the discrete nonlinear Schrödinger equation (DNLS) with suitable random initial data. We also present a reformulation of the standard perturbation expansion using cumulants which could simplify the problem of a rigorous derivation of the Boltzmann-Peierls equation by separating the analysis of the solutions to the Boltzmann-Peierls equation from the analysis of the corrections. This latter scheme is general and not tied to the DNLS evolution equations.
