Understanding and monitoring oil migration in multiphase chocolate products
Creators: name: Waxman, Sarah
Publisher: name: No Publisher Supplied
Year: 2023

description: Multiphasic chocolate products are subject to the inevitable phenomenon of oil migration, which is the predominant mode for loss of quality due to consequent undesirable changes in texture and fat bloom formation. Numerous studies aim to study oil migration utilizing model systems whereby the chocolate and model fat phases are in close contact; however, few studies utilize commercially available products due to their complexity. Although chocolate is predominately composed of cocoa butter, measurements relying on ideal systems do not account for significant contribution of the minor components to the structure of a chocolate system. The objective of this work was to visualize and quantify oil migration as a function of time in complex chocolate systems using Nile Red (NR) as a fluorescent probe and fluorescence confocal laser scanning microscopy (CLSM), to image the spatial distribution of migrated stained fat. It was found that by applying Fick's 2nd law to characterize the mass transfer of the oil phase into the chocolate system, relative comparisons about the affinity of a system to uptake oil can be made between systems with varying experimental conditions including storage temperature, source of migrating oil phase, and thermal abusive and/or mitigating conditions. The relative affinity of a system to undergo oil migration after being exposed to thermally abusive conditions was able to be further understood by assessing crystallization and melt properties of associated samples via the use of DSC. DSC studies revealed that the presence of oil in chocolate, resulting from migration, leads to a decrease in the crystallization and melt temperature of the chocolate. NR and CLSM were found to enable an effective method to characterize oil migration in multiphase chocolate products to understand the factors that influence the relative extent of oil migration, and thus, the stability of a multiphase chocolate product.

description: A non-parametric conditional density estimation algorithm for nonlinear stochastic dynamic systems is proposed. The contributions are a novel sup- port vector regression for estimating conditional den- sities, modeled by Gaussian mixture densities, and an algorithm based on cross-validation for automatically determining hyper-parameters for the regression. The conditional densities are employed with a modi?ed axis- aligned Gaussian mixture filter. The experimental va- lidation shows the high quality of the conditional densi- ties and good accuracy of the proposed filter.

description: Effects of non-magnetic randomness on the critical temperature T_c and diamagnetism are studied in a class of quasi-one dimensional superconductors. The energy of Josephson-coupling between wires is considered to be random, which is typical for dirty organic superconductors. We show that this randomness destroys phase coherence between the wires and T_c vanishes discontinuously when the randomness reaches a critical value. The parallel and transverse components of the penetration depth are found to diverge at different critical temperatures T_c^{(1)} and T_c, which correspond to pair-breaking and phase-coherence breaking. The interplay between disorder and quantum phase fluctuations results in quantum critical behavior at T=0, manifesting itself as a superconducting-normal metal phase transition of first-order at a critical disorder strength.

Bounding Linearization Errors with Sets of Densities in Approximate Kalman Filtering

Publisher: name: Karlsruhe
Year: 2010

description: Applying the Kalman filtering scheme to linearized system dynamics and observation models does in general not yield optimal state estimates. More precisely, inconsistent state estimates and covariance matrices are caused by neglected linearization errors. This paper introduces a concept for systematically predicting and updating bounds for the linearization errors within the Kalman filtering framework. To achieve this, an uncertain quantity is not characterized by a single probability density anymore, but rather by a set of densities and accordingly, the linear estimation framework is generalized in order to process sets of probability densities. By means of this generalization, the Kalman filter may then not only be applied to stochastic quantities, but also to unknown but bounded quantities. In order to improve the reliability of Kalman filtering results, the last-mentioned quantities are utilized to bound the typically neglected nonlinear parts of a linearized mapping.

The emergence of probabilities in anhomomorphic logic

description: Anhomomorphic logic is a new interpretation of Quantum Theory (due to R. Sorkin). It is a histories formulation (c.f. consistent histories, quantum measure theory). In this approach, reality is a co-event, which is essentially an assignment of a truth value {True, False} to each question. The way this assignment is done mimics classical physics in as much as possible allowing however for sufficient flexibility to accommodate quantum 'paradoxes', as is shown by the analysis of Kochen-Specker theorem. In this contribution, after briefly reviewing the approach, we will examine how probabilistic predictions can arise. The Cournot principle and the use of approximate preclusions will play a crucial role. Facing similar problems in interpreting probability as in classical probability theory, we will resort to the weak form of Cournot principle, where possible realities will be preclusive co-events and the quantum measure is used to obtain predictions. Examples considered, includes the fair coin and the double slit pattern arguably one of the most important paradigms for quantum theory.

Το δείγμα καλύπτει την περίοδο 2010-2019 και περιλαμβάνει εισηγμένες εταιρείες από τις χρηματαγορές της Αμερικής. Τα αποτελέσματα της μελέτης καταδεικνύουν πως το ROE και το ROA επηρεάζεται θετικά από το γενικό ESG score καθώς και από την περιβαλλοντική και διακυβερνητική απόδοση ενώ στον αντίποδα δεν προέκυψε στατιστικά σημαντική σχέση μεταξύ οικονομικής και κοινωνικής απόδοσης. Επίσης καταλήξαμε σε μη στατιστικά σημαντική σχέση χρησιμοποιώντας τον Tobin’ s Q ως δείκτη μέτρησης της απόδοσης της αγοράς. Συνεπώς, βάσει αποτελεσμάτων, η θετική συσχέτιση της βαθμολογίας ESG και της οικονομικής απόδοσης ενισχύει την θεωρία των ενδιαφερομένων (stakeholder theory) ενώ αντιθέτως, δεν προέκυψαν επαρκή στοιχεία που να ενισχύουν την θεωρία των μετόχων (share holder theory) βάσει της οποίας η εταιρική κοινωνική ευθύνη είναι ένα περιττό κόστος για μια εταιρεία. Σε αυτή την περίπτωση θα αναμέναμε μια ξεκάθαρη αρνητική σχέση η οποία δεν προέκυψε από την έρευνα μας.

A Log-Ratio Information Measure for Stochastic Sensor Management

Publisher: name: Karlsruhe
Year: 2010

description: In distributed sensor networks, computational and energy resources are in general limited. Therefore, an intelligent selection of sensors for measurements is of great importance to ensure both high estimation quality and an extended lifetime of the network. Methods from the theory of model predictive control together with information theoretic measures have been employed to pick sensors yielding measurements with high information value. We present a novel information measure that originates from a scalar product on a class of continuous probability densities and apply it to the field of sensor management. Aside from its mathematical justifications for quantifying the information content of probability densities, the most remarkable property of the measure, an analogon of the triangle inequality under Bayesian information fusion, is deduced. This allows for deriving computationally cheap upper bounds for the model predictive sensor selection algorithm and for comparing the performance of planning over different lengths of time horizons.
A study of artificial destratification of fresh water lakes
Creators: name: Ritchie, John Clarke Weldon
Publisher: name: University of British Columbia
Year: 2011

description: The water quality characteristics of various lake classifications are discussed and are related to the natural physical and biological development of lakes. The impact of human activity on this natural trend is considered. The results of an extensive literature search are presented, discussing seasonal variations in water quality in fresh water lakes. Methods of altering water quality are outlined, with particular emphasis on the artificial elimination of summer thermal stratification. Results of observations made of Osoyoos Lake during the summers of 1969 and 1970 are presented. Tests of an aeration installation in the lake are reported and discussed. Laboratory investigations into the mechanisms of destratification are described. Simulation of thermal stratification was achieved through the use of a fresh water-salt water system. Three destratification devices were tested under various stratification conditions and their energy requirements are compared. Discussion of the results includes some comments on the reliability of stability and energy criteria for the evaluation of such devices.
Why Concerts are Chimerical: The Structural Failure of Concert Systems
Creators: name: Björnsson, Ólafur
Publisher: name: University of Chicago
Year: 2023

description: Do Concerts enable great powers to ameliorate security competition, or are they forums for security competition where each great power tries to abuse the Concert for their own advantage? The return of great power politics in the 21st century, evinced by the rise of China and a resurgent Russia, has incentivized scholars of International Relations to examine great power Concerts and their potential impact on security competition. While some scholars argue that Concerts can be a benevolent platform that mitigates security competition between great powers, I argue the opposite, namely that the great powers that comprise a Concert have a structural incentive to abuse the Concert to gain relative power and security competition will therefore persist. By carefully analyzing the historical evidence of the only case of an attempted Concert, the Concert of Europe, I demonstrate that Austria successfully abused the Concert to advance her interests to the detriment of the other great powers. This abuse was most evident when the gaze of Europe turned to Italy in the wake of the Neapolitan Revolution, and the European great powers assembled at Troppau and Laibach to address the revolution. During these great power conferences, Metternich, the Austrian Foreign Minister, successfully turned the Concert into a tool of Austrian statecraft, heralding the end of the Concert of Europe in its original form.

description: We simulate numerically the full dynamics of Faraday waves in three dimensions for two incompressible and immiscible viscous fluids. The Navier-Stokes equations are solved using a finite-difference projection method coupled with a front-tracking method for the interface between the two fluids. The domain of calculation is periodic in the horizontal directions and bounded in the vertical direction by two rigid horizontal plates. The critical accelerations and wavenumbers, as well as the temporal behaviour at onset are compared with the results of the linear Floquet analysis of Kumar and Tuckerman [J. Fluid Mech. 279, 49-68 (1994)]. The finite amplitude results are compared with the experiments of Kityk et al. [Phys. Rev. E 72, 036209 (2005)]. In particular we reproduce the detailed spatiotemporal spectrum of both square and hexagonal patterns within experimental uncertainty.

description: With the development of technology and e-commerce, consumers’ online shopping behavior is a popular field being explored by many researchers, especially regarding its factors involving social environments, features of products, merchants activities and customers’ own characteristics. As the outbreak of COVID-19 pandemic, the online grocery sales shows an increasing trend. Regarding the driving force of the increase, how have different consumer groups’ online grocery shopping behavior been affected by the pandemic differently? The paper investigates the question using the first-hand data obtained from a survey with 905 responses via Amazon Mechanical Turk platform. The survey is designed concerning customers’ demographic features including age, gender, education and income, and also shopping behavior including shopping frequency, spending and choice of channel. The analysis relies on methods including descriptive statistics, Spearman Correlation Coefficient, McNemar test, Logistic regression and OLS regression. Results suggest that customers’ age, gender and household plays a role in the heterogeneity in the influence of the pandemic on online grocery shopping.
Time delay for dispersive systems in quantum scattering theory

description: We consider time delay and symmetrised time delay (defined in terms of sojourn times) for quantum scattering pairs $\{H_0=h(P),H\}$, where $h(P)$ a dispersive operator of hypoelliptic-type. For instance $h(P)$ can be one of the usual elliptic operators such as the Schrödinger operator $h(P)=P^2$ or the square-root Klein-Gordon operator $h(P)=\sqrt{1+P^2}$. We show under general conditions that the symmetrised time delay exists for all smooth even localization functions. It is equal to the Eisenbud-Wigner time delay plus a contribution due to the non-radial component of the localization function. If the scattering operator $S$ commutes with some function of the velocity operator $\nabla h(P)$, then the time delay also exists and is equal to the symmetrised time delay. As an illustration of our results we consider the case of a one-dimensionnal Friedrichs Hamiltonian perturbed by a finite rank potential. Our study put into evidence an integral formula relating the operator of differentiation with respect to the kinetic energy $h(P)$ to the time evolution of localization operators.

Optimal Dirac Approximation by Exploiting Independencies
Creators: name: Eberhardt, Henning

Publisher: name: Karlsruhe
Year: 2010

description: The sample-based recursive prediction of discrete-time nonlinear stochastic dynamic systems requires a regular reapproximation of the Dirac mixture densities characterizing the state estimate with an exponentially increasing number of components. For that purpose, a systematic approximation method is proposed that is deterministic and guaranteed to minimize a new type distance measure, the so called modified Cram\'{e}r-von Mises distance. A huge increase in approximation performance is achieved by exploiting structural independencies usually occurring between the random variables used as input to the system. The corresponding prediction step achieves optimal performance when no further assumptions can be made about the system function. In addition, the proposed approach shows a much better convergence compared to the prediction step of the particle filter and by far fewer Dirac components are required for achieving a given approximation quality. As a result, the new approximation method opens the way for the development of new fully deterministic and optimal stochastic state estimators for nonlinear dynamic systems.

description: The structure of the superconducting gap provides important clues on the symmetry of the order parameter and the pairing mechanism. The presence of nodes in the gap function imposed by symmetry implies an unconventional order parameter, other than s-wave. Here we show how measurements of the thermal conductivity at very low temperature can be used to determine whether such nodes are present in a particular superconductor, and shed light on their nature and location. We focus on the residual linear term at T goes to 0. A finite value in zero magnetic field is strong evidence for symmetry-imposed nodes, and the dependence on impurity scattering can distinguish between a line of nodes or point nodes. Application of a magnetic field probes the low-energy quasiparticle excitations, whether associated with nodes or with a small value of the gap on some part of the Fermi surface, as in a multi-band superconductor. We frame our discussion around archetypal materials: Nb for s-wave, Tl2Ba2CuO(6+δ) for d-wave, Sr2RuO4 for p-wave, and NbSe2 for multi-band superconductivity. In that framework, we discuss three heavy-fermion superconductors: CeIrIn5, CeCoIn5 and UPt3.

description: We examine the problem of determining whether a multiqubit two-local Hamiltonian can be made stoquastic by single-qubit unitary transformations. We prove that when such a Hamiltonian contains one-local terms, then this task can be NP-hard. This is shown by constructing a class of Hamiltonians for which performing this task is equivalent to deciding 3-SAT. In contrast, we show that when such a Hamiltonian contains no one-local terms then this task is easy; namely, we present an algorithm which decides, in a number of arithmetic operations over $\mathbb{R}$ which is polynomial in the number of qubits, whether the sign problem of the Hamiltonian can be cured by single-qubit rotations.

Explosive percolation in scale-free networks

description: We study scale-free networks constructed via a cooperative Achlioptas growth process. Links between nodes are introduced in the network in order to produce a scale-free graph with given exponent lambda for the degree distribution, but the choice of each new link depends on the mass of the clusters that this link will merge. Networks constructed via this biased procedure show a percolation transition which strongly differs from the one observed in standard percolation, where links are introduced just randomly. The different growth process leads to a phase transition with a non-vanishing percolation threshold already for lambda > lambda_c ~ 2.2. More interestingly, the transition is continuous when lambda <= 3 but becomes discontinuous when lambda > 3. This may have important consequences both for the structure of networks and for the dynamics of processes taking place on them.

description: Aims: Heart failure (HF) is frequent in patients with acute ischaemic stroke (AIS) and associated with higher morbidity and mortality. Assessment of cardiac function in AIS patients using cardiovascular MRI (CMR) may help to detect HF. We report the rate of systolic and diastolic dysfunction in a cohort of patients with AIS using CMR and compare cine real-time (CRT) sequences with the reference of segmented cine steady-state free precession sequences. Methods and results: Patients with AIS without known atrial fibrillation were prospectively enrolled in the HEart and BRain Interfaces in Acute Ischemic Stroke (HEBRAS) study (NCT 02142413) and underwent CMR at 3 Tesla within 7 days after AIS. Validity of CRT sequences was determined in 50 patients. A total of 229 patients were included in the analysis (mean age 66 years; 35% women; HF 2%). Evaluation of cardiac function was successful in 172 (75%) patients. Median time from stroke onset to CMR was 82 h (interquartile range 56-111) and 54 h (interquartile range 31-78) from cerebral MRI to CMR. Systolic dysfunction was observed in 43 (25%) and diastolic dysfunction in 102 (59%) patients. Diagnostic yield was similar using CRT or segmented cine imaging (no significant difference in left ventricular ejection fraction, myocardial mass, time to peak filling rate, and peak filling rate ratio E/A). lntraobserver and interobserver agreement was high (kappa = 0.78-1.0 for all modalities). Conclusions: Cardiovascular MRI at 3 Tesla is an appropriate method for the evaluation of cardiac function in a selected cohort of patients with AIS. Systolic and diastolic dysfunction is frequent in these patients. CRT imaging allows reliable assessment of systolic and diastolic function.
Uncovering the Outflow Driven by the Brown Dwarf LS-RCr A1: H-alpha as a Tracer of Outflow Activity in Brown Dwarfs

description: It is now apparent that classical T Tauri-like outflows commonly accompany the formation of young brown dwarfs. To date two optical outflows have been discovered and results presented in this paper increase this number to three. Using spectro-astrometry the origin of the LS-RCrA 1 forbidden emission lines in a blue-shifted outflow is confirmed. The non-detection of the red-shifted component of the outflow in forbidden lines, along with evidence for some separation between low and high velocity outflow components, do not support the hypothesis that LS-RCrA 1 has an edge-on accretion disk. The key result of this analysis is the discovery of an outflow component to the H-alpha line. The H-alpha line profile has blue and red-shifted features in the wings which spectro-astrometry reveals to also originate in the outflow. The discovery that H-alpha emission in BDs can have a significant contribution from an outflow suggests the use of H-alpha line widths as a proxy of mass accretion in BDs is not clear-cut. This method assumes that any contribution to the H-alpha line flux from a possible outflow is negligible. Finally the fact that the H-alpha line traces both lobes of the outflow while only the blue-shifted lobe is seen in forbidden emission points to the presence of a dust hole in the accretion disk of LS-RCrA 1. This is commonly seen in CTTSs and is assumed to signal the onset of planet formation.

description: The paper suggests a possible interpretation of Stultitia, one of Giotto’s Vices in the Scrovegni chapel, in relationship to the medical definitions belonging to Aristotelic tradition, and in connection with the alienationes mentis, to which also melancholy belongs. And this feeling – perhaps again on the basis of the medicine usage, and of a first in nuce definition of the scholar’s iconography – can have a role in the facing Virtue, Prudentia.

description: An accurate calculation of the properties of quantum many-body systems is one of the most important yet intricate challenges of modern physics and computer science. In recent years, the tensor network ansatz has established itself as one of the most promising approaches enabling striking efficiency of simulating static properties of one-dimensional systems and abounding numerical applications in condensed matter theory. In higher dimensions, however, a connection to the field of computational complexity theory has shown that the accurate normalization of the two-dimensional tensor networks called projected entangled pair states (PEPS) is #P-complete. Therefore an efficient algorithm for PEPS contraction would allow solving exceedingly difficult combinatorial counting problems, which is considered highly unlikely. Due to the importance of understanding two- and three-dimensional systems the question currently remains: Are the known constructions typical of states relevant for quantum many-body systems? In this work, we show that an accurate evaluation of normalization or expectation values of PEPS is as hard to compute for typical instances as for special configurations of highest computational hardness. We discuss the structural property of average-case hardness in relation to the current research on efficient algorithms attempting tensor network contraction, hinting at a wealth of possible further insights into the average-case hardness of important problems in quantum many-body theory.
Parameter Learning for Hybrid Bayesian Networks With Gaussian Mixture and Dirac Mixture Conditional Densities

name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2010

description: In this paper, the first algorithm for learning hybrid Bayesian Networks with Gaussian mixture and Dirac mixture conditional densities from data given their structure is presented. The mixture densities to be learned allow for nonlinear dependencies between the variables and exact closedform inference. For learning the network's parameters, an incremental gradient ascent algorithm is derived. Analytic expressions for the partial derivatives and their combination with messages are presented. This hybrid approach subsumes the existing approach for purely discrete-valued networks and is applicable to partially observable networks, too. Its practicability is demonstrated by a reference example.

description: In this contribution, we propose a new framework to evaluate pedestrian simulations by using Extended Range Telepresence. Telepresence is used as a virtual reality walking simulator, which provides the user with a realistic impression of being present and walking in a virtual environment that is much larger than the real physical environment, in which the user actually walks. The validation of the simulation is performed by comparing motion data of the telepresent user with simulated data at some points of the simulation. The use of haptic feedback from the simulation makes the framework suitable for training in emergency situations.
Structural dynamic properties from ambient vibrations
Creators: name: Topf, Ulf Andreas
Publisher: name: University of British Columbia
Year: 2011

description: Ambient vibrations of a reinforced concrete tower structure were recordedand analyzed to obtain the natural frequencies, the associated mode shapes and an estimate of the equivalent viscous damping. The structure investigated consists of four concrete wall panels,rigidly connected at various levels and contains a light precast concrete stairwell. It is similar to typical components of larger structures,such as stairwells and elevator shafts or cores. The given information should be useful in offering details of the dynamic behaviour of this type of structural elements. The experimental results are compared with the theoretical results obtained from two- and three-dimensional dynamic analyses using matrix methods applied to linear elastic systems with lumped masses. An efficient computer program to find the eigenvalues and eigenvectors for this type of mathematical model is described.
