Quasar Populations in a Cosmological Constant Dominated Flat Universe

Publisher: name: arXiv
Year: 1994
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Most physical properties derived for quasars, as single entities or as a population, depend upon the cosmology assumed. In this paper, we calculate the quasar luminosity function and some related quantities for a flat universe dominated by a cosmological constant $Λ$ ($Λ=0.9, Ω=0.1$) and compare them with those deduced for a flat universe with zero cosmological constant ($Λ=0,Ω=1$). We use the AAT quasar survey data (Boyle et al. 1990) as input in both cases. The data are fit well by a pure luminosity evolution model for both the cosmologies, but with different evolutionary parameters. From the luminosity function, we predict (extrapolate) a greater number of quasars at faint apparent magnitudes (twice the number at B=24, $z < 2.2$) for the $Λ$ dominated universe. This population of faint quasars at high redshift would result in a higher incidence of gravitational lensing. The total luminosity of the quasar population and the total mass tied up in black hole remnants of quasars is not sensitive to the cosmology. However, for a $Λ$ cosmology this mass is tied up in fewer but more massive black holes.

Why do we want to defer actions on climate change? A psychological perspective

description: A 2007 U.N. survey found that 54% of Americans advocate ―wait-and-see‖ behavior on policies that mitigate climate change, i.e., they infer that climate mitigation actions can be deferred until there are clear signs of danger. By evaluating different cognitive factors that influence human behavior, this thesis builds a framework that provides answers to an important question: why do people advocate wait-and-see behavior on climate change? One cognitive factor is misperceptions of feedback (i.e., ignorance of large feedback delays between CO2 emission decisions and the corresponding changes in CO2 concentration). Results reveal that the use of simulation tools, that provide repeated feedback about decision actions and corresponding consequences, is likely to enable people to overcome these misperceptions. A second factor is people‘s reliance on correlational or linear thinking (that the shape of CO2 emissions and CO2 concentration should look alike). Results reveal that the use of a physical representation (i.e., a picture of a problem in the form of a metaphor), simulation tools, and presenting problems such people‘s reliance on heuristics and biases enables them to make ecofriendly decisions is likely to enable people to overcome their correlational thinking. Other cognitive factors that affect people‘s wait-and-see behavior include people‘s risk and time preferences about future climate consequences when these consequences are either described or experienced. Results reveal that descriptive methods (e.g., books, newspapers, and reports) are likely to produce more wait-and-see behavior due to a high probability, small cost, and late timing of future consequences; whereas, experiential methods (e.g., movies, imagery, and games) are likely to produce more wait-and-see behavior due to a low probability, large cost, and early timing of future consequences. Policy implications suggest a careful design of descriptive and experiential climate risk communication methods, and the use of above described manipulations to improve people‘s decision making on climate change.

subject: RFM

description: Customer churn, or customer attrition, is a major concern for many companies because acquiring new customers is much more expensive than retaining existing ones. Customers may stop purchasing for diverse reasons: financial problems, switch to competitors, dissatisfaction of the products, etc. Getting insights on these reasons may help companies to adapt their business strategy. Therefore, an accurate identification of churned and churning customers is desirable. In this master thesis, we develop a method to detect such behaviors for Siemens customers. Most of the methods found in the literature are supervised which means that the data sets on which they are applied have already labels "churned" and "not churned". This is the case for the contract-based businesses in the domain of telecommunications. In non-contractual business, like Siemens, defining if a customer is churned or not is more challenging. Siemens customers also exhibit very different behaviors such as non-constant purchase frequencies over time that results in making state-of-the-art methods like the RFM (Recency-Frequency-Monetary) fail. Wavelets and their associated scaleograms identify purchase decreases across a range of frequencies predefined from past customer purchase behavior. Wavelets allow the estimation of thresholds to identify churned customers. The wavelet-based method developed in this thesis can be applied to other kinds of data sets especially on non-stationary signals of a high frequency variability over time.

description: We propose a method for entangling two non-interacting qubits by measuring their parity indirectly through an intermediate mesoscopic system. The protocol is designed to require only global control and course-grained collective measurement of the mesoscopic system along with local interactions between the target qubits and mesoscopic system. A generalization of the method measures the hamming weight of the qubits' state and probabilistically produces an entangled state by post-selecting on hamming weight one. Our technique provides a new design element that can be integrated into quantum processor architectures and quantum measurement devices.

TAILORING THE OPTICAL PROPERTIES OF ALTERNATIVE NANOMATERIALS

description: Having precise knowledge about the dielectric function of materials is of high importance for the successful development of high-performance plasmonic-based nanophotonic devices. While this essential function is in general constant and well-established for bulk materials, as we approach the ultrathin regime their optical behavior starts to differ from the bulk due to multiple reasons, including grain scattering, crystallinity, surface roughness or quantum effects amongst others. Such differences can be regarded as an experimental problem, but are in fact a source of new opportunities to access exciting ultrathin nanomaterials with tailorable optical properties, which could potentially serve as building blocks for novel nanophotonic devices.

In this work, we present Bismuth (Bi) and Antimony (Sb) ultra thin films prepared by pulsed laser deposition as alternative materials  for nanophotonics, in particular for non-diffractive structural color generation built directly on technologically important substrates, such as Si or Steel.

Publisher: name: Carnegie Mellon University
Year: 2015
Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: This research is an investigation of heat transfer from a flat plate using water spray cooling at system pressures that are below standard atmospheric pressure. The focus is on those system pressures below the triple point of water. At the triple point of water, the three phases are in equilibrium: liquid, vapor and solid, at 0.01°C and 612 Pa (4.6 Torr). There are many possible applications of this research, including in space and on earth. In addition to spacecraft applications, this research may apply to vacuum seawater desalination, preservation of biologically active samples, water purification, food storage, and electronics cooling. Experiments were performed to quantify the heat transfer and provide evidence to support the heat transfer mechanism and model. For sprays or any droplet deposition system that can generate discrete small droplets on a surface, this research provides a predictive model to estimate the heat transfer, and experimental data to support the model.

description: We study geometrically thick and non-self gravitating equilibrium tori orbiting a static spherically symmetric dyonic black hole with quasi-topological electromagnetism. Our results show that the electric and magnetic charges together with the coupling parameter in the quasi-topological electromagnetism lead to a much richer class of equilibrium tori. There are a range of parameters which allow for the existence of double tori. The properties of double equilibrium tori become far richer. There exist transitions between single torus and double tori solutions as we change the specific angular momentum of the fluid. These properties of equilibrium tori could help to understand the dyonic black hole and its thick accretion disk.

Weak Non Self-Averaging Behaviour for Diffusion in a Trapping Environment

description: The statistics of equally weighted random paths (ideal polymer) is studied in $2$ and $3$ dimensional percolating clusters. This is equivalent to diffusion in the presence of a trapping environment. The number of $N$ step walks follows a log-normal distribution with a variance growing asymptotically faster than the mean which leads to a weak non self-averaging behaviour. Critical exponents associated with the scaling of the two-points correlation function do not obey standard scaling laws.

Data-Driven Distributionally Robust Optimal Power Flow for Distribution Systems

Publisher: name: arXiv
Year: 2018
Subjects: subject: Optimization and Control (math.OC)

description: Increasing penetration of distributed energy resources complicate operations of electric power distribution systems by amplifying volatility of nodal power injections. On the other hand, these resources can provide additional control means to the distribution system operator (DSO). This paper takes the DSO perspective and leverages a data-driven distributionally robust decision-making framework to overcome the uncertainty of these injections and its impact on the distribution system operations. We develop an AC OPF formulation for radial distribution systems based on the LinDistFlow AC power flow approximation and exploit distributionally robust optimization to immunize the optimized decisions against uncertainty in the probabilistic models of forecast errors obtained from the available observations. The model is reformulated to be computationally tractable and tested on multiple IEEE distribution test systems. We also release the code supplement that implements the proposed model in Julia and can be used to reproduce our numerical results.

description: The recent framework of compressive statistical learning aims at designing tractable learning algorithms that use only a heavily compressed representation-or sketch-of massive datasets. Compressive K-Means (CKM) is such a method: it estimates the centroids of data clusters from pooled, non-linear, random signatures of the learning examples. While this approach significantly reduces computational time on very large datasets, its digital implementation wastes acquisition resources because the learning examples are compressed only after the sensing stage. The present work generalizes the sketching procedure initially defined in Compressive K-Means to a large class of periodic nonlinearities including hardware-friendly implementations that compressively acquire entire datasets. This idea is exemplified in a Quantized Compressive K-Means procedure, a variant of CKM that leverages 1-bit universal quantization (i.e. retaining the least significant bit of a standard uniform quantizer) as the periodic sketch nonlinearity. Trading for this resource-efficient signature (standard in most acquisition schemes) has almost no impact on the clustering performances, as illustrated by numerical experiments.

description: Il settore occidentale dell'area metropolitana finlandese viene attualmente definito come la più vasta concentrazione di high-tech e di know-how della Fennoscandia. Il nucleo trainante del sistema è costituito dal comune di Espoo e dalla sua frazione di Tapiola. Nel presente lavoro si intende riflettere sulla evoluzione territoriale in atto in tale area, mettendo in special modo in evidenza i cambiamenti intervenuti nella piccola cittadina di Tapiola. Questa, infatti, era stata pianificata e realizzata come città-giardino nella previsione di un sufficiente grado di autonomia (capace cioè di non far dipendere totalmente il centro dalla vicinissima Helsinki); attualmente, invece, Tapiola è divenuta un centro locale dell'area metropolitana, contraddistinto da intensi scambi bidirezionali con la capitale. All'interno di questo percorso si porranno in luce non soltanto le varie fasi storiche del processo ma, soprattutto, quegli elementi territoriali specifici che hanno generato ed orientato tale evoluzione. Tra questi si metterà in rilievo l'importanza dell'essenza stessa della città-giardino, nella creazione di un milieu a servizio dell'high-tech e del know-how ed il ruolo giocato dall'istituzione universitaria nella formazione di un sistema spaziale innovativo.

description: Local (first order) sentences, introduced by Ressayre, enjoy very nice decidability properties, following from some stretching theorems stating some remarkable links between the finite and the infinite model theory of these sentences. We prove here several additional results on local sentences. The first one is a new decidability result in the case of local sentences whose function symbols are at most unary: one can decide, for every regular cardinal k whether a local sentence phi has a model of order type k. Secondly we show that this result can not be extended to the general case. Assuming the consistency of an inaccessible cardinal we prove that the set of local sentences having a model of order type omega_2 is not determined by the axiomatic system ZFC + GCH, where GCH is the generalized continuum hypothesis

description: The growing family of two-dimensional (2D) materials that are now available can be used to assemble van der Waals heterostructures with a wide range of properties. Of particular interest are tunnelling heterostructures, which have been used to study the electronic states both in the tunnelling barrier and in the emitter and collector contacts. Recently, 2D ferromagnets have been studied theoretically and experimentally. Here we investigate electron tunnelling through a thin (2-6 layers) ferromagnetic CrBr3 barrier. For devices with non-magnetic barriers, conservation of momentum can be relaxed by phonon-assisted tunnelling or by tunnelling through localised states. In the case of our ferromagnetic barrier the dominant tunnelling mechanisms are the emission of magnons at low temperatures or scattering of electrons on localised magnetic excitations above the Curie temperature. Tunnelling with magnon emission offers the possibility of injecting spin into the collector electrode.
Noncommutative 3-colour scalar quantum field theory model in 2D

description: We introduce the 3-colour noncommutative quantum field theory model in two dimensions. For this model we prove a generalised Ward-Takahashi identity, which is special to coloured noncommutative QFT models and has no underlying continuous symmetry. It reduces to the usual Ward-Takahashi identity in a particular case. The Ward-Takahashi identity is used to simplify the Schwinger-Dyson equations for the 2-point function and the N-point function. The absence of any renormalisation conditions in the large $(\mathcal{N},V)$-limit in 2D leads to a recursive integral equation for the 2-point function, which we solve perturbatively to sixth order in the coupling constant.

description: If finite but tiny masses of the three active neutrinos are generated via the canonical seesaw mechanism with three heavy sterile neutrinos, the 3\times 3 Pontecorvo-Maki-Nakagawa-Sakata neutrino mixing matrix V will not be exactly unitary. This kind of indirect unitarity violation can be probed in a precision reactor antineutrino oscillation experiment, but it may be entangled with terrestrial matter effects as both of them are very small. We calculate the probability of \overlineν_e \to \overlineν_e oscillations in a good analytical approximation, and find that, besides the zero-distance effect, the effect of unitarity violation is always smaller than matter effects, and their entanglement does not appear until the next-to-leading-order oscillating terms are taken into account. Given a 20-kiloton JUNO-like liquid scintillator detector, we reaffirm that terrestrial matter effects should not be neglected but indirect unitarity violation makes no difference, and demonstrate that the experimental sensitivities to the neutrino mass ordering and a precision measurement of θ_{12} and Δ_{21} \equiv m^2_2 - m^2_1 are robust.

description: The comprehensive, understandable and effective formal specification of
 complex systems is often difficult, especially for reactive and interactive
 systems like web services or embedded system components.
 In this paper, we propose \emph{contract automata}, a new specification
 formalism for describing the expected behaviour of stateful systems. Contract
 automata combine two established concepts for formal system specification:
 contract-based specification and nondeterministic finite state automata.
 Contract automata restrict the effects that the operations of the specified
 system may have using input-output-contracts. The automaton structure of a
 contract automaton describes when contracts are applicable.
 Contract automata support the refinement and composition of reactive systems,
 enabling modular verification of systems assembled of multiple subsystems.
 In this paper, we formally define the semantics of contract automata based on
 a two-party game between the system under test and its environment.
 We define the proof obligations and present techniques to prove a refinement
 relationship between contract automata, the validity of system compositions, and
 the compliance of source code against a contract automaton.
 We provide a tool for the generation of the proof obligation that can be
 discharged with model-checkers or static program analyses.
 We exemplify the use of contract automata by presenting the specification and
 verification of an emergency brake assistant.

description: The interaction between two-level systems (TLS) and strain fields in a solid is contained in the diagonal matrix element of the interaction hamiltonian, $δ$, which, in general, has the expression $δ=2[γ]:[S]$, with the tensor $[γ]$ describing the TLS ``deformability'' and $[S]$ being the symmetric strain tensor. We construct $[γ]$ on very general grounds, by associating to the TLS two objects: a direction, $\hat\bt$, and a forth rank tensor of coupling constants, $[[R]]$. Based on the method of construction and on the invariance of the expression of $δ$ with respect to the symmetry transformation of the solid, we conclude that $[[R]]$ has the same structure as the tensor of stiffness constants, $[[c]]$, from elasticity theory. In particular, if the solid is isotropic, $[[R]]$ has only two independent parameters, which are the equivalent of the Lamé constants. Employing this model we calculate the absorption and emission rates of phonons on TLSs and show that in isotropic solids, on average, the longitudinal phonons interact stronger with the TLSs than the transversal ones, as it is observed in experiments. We also show that in isotropic solids, a transversal wave leaves unperturbed all the TLSs with the direction contained in one of the two planes that are perpendicular either to the wave propagation direction or to the polarization direction and that a longitudinal strain applied to the solid polarises the TLS ensemble.

description: We calculate the electromagnetic multipole moments of the $P_c^+(4380)$ pentaquark by modeling it as the diquark-diquark-antiquark and $\bar D^*Σ_c$ molecular state with quantum numbers $J^P = \frac{3}{2}^-$. In particular, the magnetic dipole, electric quadrupole and magnetic octupole moments of this particle are extracted in the framework of light-cone QCD sum rule. The values of the electromagnetic multipole moments obtained via two pictures differ substantially from each other, which can be used to pin down the underlying structure of $P_c^+(4380)$. The comparison of any future experimental data on the electromagnetic multipole moments of the $P_c^+(4380)$ pentaquark with the results of the present work can shed light on the nature and inner quark organization of this state.

description: There is an increasing demand for next-generation flexible electronics in emerging low-cost applications such as smart packaging and smart bandages, where conventional silicon electronics cannot enter due to cost and form factor. In these domains, ultra-low-cost, high flexibility, and customizability are required. In this regard, printed electronics emerge as a complementary solution offering the aforementioned properties. To respect the constraints in those application scenarios and equip printed devices with the fundamental capability to process information, analog printed neuromorphic circuits offer multiple advantages, including strong expressiveness, streamlined circuit primitives, and a highly efficient machine learning-based design process. In this work, we focus on designing low-power printed neuromorphic circuits at the algorithmic level. By developing accurate power models for the circuit primitives, the power consumption can be considered into the design process. Subsequently, Pareto analysis is employed to examine the relationship between accuracy and power consumption. Experimental results reveal that, with the proposed approach, 2× reduction of the power consumption can be realized while maintaining 95% of classification accuracy. This approach has significant implications for the future development of energy-efficient printed neuromorphic circuits and their potential applications in IoT and AI intersections.

description: La tematica turistica, e in particolar modo quella della "seconda casa", hanno visto fiorire in questi ultimi anni un'ampia letteratura. Paradigmi sistemici e modelli generali di organizzazione dello spazio turistico sono stati alla base di studi e di valutazioni, che hanno riconosciuto al turismo un ruolo di attività motrice nelle trasformazioni economiche e territoriali. Sempre più si va delineando uno scenario nuovo, ricco di relazioni e di interdipendenze culturali, sociali e di costume, coniugate a iniziative imprenditoriali in grado di favorire l'ingresso e l'affermazione di variegate forme turistiche. Infatti, la necessità, da parte del mercato, di un continuo e costante aggiornamento del prodotto, diversificando e variegando l'offerta, in seguito ad una domanda crescente di alloggi per vacanze, si è recentemente concretizzata nella realizzazione di nuove "strutture di accoglienza" ad uso turistico-residenziale. Proprio in tale ambito si colloca quest'indagine volta ad esaminare una particolare forma di "occupazione" turistica del suolo: la multiproprietà.

description: In this article we consider a bosonic Josephson junction, a model system composed by two coupled nonlinear quantum oscillators which can be implemented in various physical contexts, initially prepared in a product of weakly populated coherent states. We quantify the maximum achievable entanglement between the modes of the junction and then use shortcuts to adiabaticity, a method developed to speed up adiabatic quantum dynamics, as well as numerical optimization, to find time-dependent controls (the nonlinearity and the coupling of the junction) which bring the system to a maximally entangled state.

description: Machine learning models are routinely integrated into process mining pipelines to carry out tasks like data transformation, noise reduction, anomaly detection, classification, and prediction. Often, the design of such models is based on some ad-hoc assumptions about the corresponding data distributions, which are not necessarily in accordance with the non-parametric distributions typically observed with process data. Moreover, the learning procedure they follow ignores the constraints concurrency imposes to process data. Data encoding is a key element to smooth the mismatch between these assumptions but its potential is poorly exploited. In this paper, we argue that a deeper insight into the issues raised by training machine learning models with process data is crucial to ground a sound integration of process mining and machine learning. Our analysis of such issues is aimed at laying the foundation for a methodology aimed at correctly aligning machine learning with process mining requirements and stimulating the research to elaborate in this direction.

Rigorous Hamiltonian and Lagrangian analysis of classical and quantum theories with minimal length

description: GUP is a phenomenological model aimed for a description of a minimal length in quantum and classical systems. However, the analysis of problems in classical physics is usually approached preferring a different formalism than the one used for quantum systems, and vice versa. Potentially, the two approaches can result in inconsistencies. Here, we eliminate such inconsistencies proposing particular meanings and relations between the variables used to describe physical systems, resulting in a precise form of the Legendre transformation. Furthermore, we introduce two different sets of canonical variables and the relative map between them. These two sets allow for a complete and unambiguous description of classical and quantum systems.

description: Spin-glasses constitute a well-grounded framework for evolutionary models. Of particular interest for (some of) these models is the lack of self-averaging of their order parameters (e.g. the Hamming distance between the genomes of two individuals), even in asymptotic limits, much as like the behavior of the overlap between the configurations of two replica in mean-field spin-glasses. In the latter, this lack of self-averaging is related to peculiar fluctuations of the overlap, known as Ghirlanda-Guerra identities and Aizenman-Contucci polynomials, that cover a pivotal role in describing the ultrametric structure of the spin-glass landscape. As for evolutionary models, such identities may therefore be related to a taxonomic classification of individuals, yet a full investigation on their validity is missing. In this paper, we study ultrametric identities in simple cases where solely random mutations take place, while selective pressure is absent, namely in {\em flat landscape} models. In particular, we study three paradigmatic models in this setting: the {\em one parent model} (which, by construction, is ultrametric at the level of single individuals), the {\em homogeneous population model} (which is replica symmetric), and the {\em species formation model} (where a broken-replica scenario emerges at the level of species). We find analytical and numerical evidence that in the first and in the third model nor the Ghirlanda-Guerra neither the Aizenman-Contucci constraints hold, rather a new class of ultrametric identities is satisfied; in the second model all these constraints hold trivially. Very preliminary results on a real biological human genome derived by {\em The 1000 Genome Project Consortium} and on two artificial human genomes (generated by two different types neural networks) seem in better agreement with these new identities rather than the classic ones.

description: Learning from rewards (i.e., reinforcement learning or RL) and learning to imitate a teacher (i.e., teacher-student learning) are two established approaches for solving sequential decision-making problems. To combine the benefits of these different forms of learning, it is common to train a policy to maximize a combination of reinforcement and teacher-student learning objectives. However, without a principled method to balance these objectives, prior work used heuristics and problem-specific hyperparameter searches to balance the two objectives. We present a $\textit{principled}$ approach, along with an approximate implementation for $\textit{dynamically}$ and $\textit{automatically}$ balancing when to follow the teacher and when to use rewards. The main idea is to adjust the importance of teacher supervision by comparing the agent's performance to the counterfactual scenario of the agent learning without teacher supervision and only from rewards. If using teacher supervision improves performance, the importance of teacher supervision is increased and otherwise it is decreased. Our method, $\textit{Teacher Guided Reinforcement Learning}$ (TGRL), outperforms strong baselines across diverse domains without hyper-parameter tuning.
