Appraisals as causes of emotions
Creators: name: Sharma, Shwetal Deepak
Publisher: name: No Publisher Supplied
Year: 2021

description: There is some disagreement among emotion researchers about what appraisals cause what emotions. To contribute to the literature, in this study, we tested hypotheses from a prominent appraisal theory of emotions (Roseman, 2011) to investigate the emotions of frustration, disgust, anger, contempt, guilt, and shame. We also compared Roseman’s appraisal (2011) hypotheses to Tracy and Robins’ appraisal (2006) hypotheses for guilt and shame.We manipulated the appraisals of agency and problem type (Roseman, 2011) to create vignettes and therefore obtain causal data. Participants were asked to compare emotions, rate emotions individually, and rate different appraisals based on the vignettes. We also investigated whether the problem type appraisal differentiates frustration from disgust, anger from contempt, and guilt from shame.We found causal evidence that problem type contributes to differentiating frustration vs. disgust (in both samples), and guilt vs. shame (in one sample). Anger (in both samples) and contempt (in one sample) were found to be caused by other person agency, and guilt and shame by self agency (in both samples). The combinations of the agency and problem type appraisals caused the predicted emotions for anger, guilt, and shame in both samples and for frustration, disgust, and contempt in one sample. We also found significant results for guilt and shame differing on problem type (Roseman, 2011) but not in controllability (Tracy & Robins, 2006).Overall, we found some support for the emotion system model (Roseman, 2011) and also compared two theories of appraisals for guilt and shame. These findings contribute to the better understanding of appraisals as causes of emotions. Problem type as being a determinant for guilt vs. shame also has implications for psychopathology, such as depression, as shame is more dysfunctional than guilt.

description: We prove a conformally invariant estimate for the index of Schrödinger operators acting on vector bundles over four-manifolds, related to the classical Cwikel-Lieb-Rozenblum estimate. Applied to Yang-Mills connections we obtain a bound for the index in terms of its energy which is conformally invariant, and captures the sharp growth rate. Furthermore we derive an index estimate for Einstein metrics in terms of the topology and the Einstein-Hilbert energy. Lastly we derive conformally invariant estimates for the Betti numbers of an oriented four-manifold with positive scalar curvature.

description: Slides from Kirstie's talk at Coding in the Open hosted by EdinbR and PyData Edinburgh on 14 June 2021 Abstract: Although reproducible research is necessary to ensure that scientific work can be trusted, it requires skills in data management, library sciences, software development, and data ethics considerations: skills that are not widely taught or expected of academic researchers. Beyond these skills lie the structural and incentive barriers to working open. The Turing Way aims to provide a safe space for data scientists in academia, industry, government and the third sector to practice these skills and build open source materials covering version control, analysis testing, collaborating in distributed groups, open and transparent communication skills, and effective management of diverse research projects. All attendees will leave Kirstie's presentation understanding the many dimensions of openness and how they can participate in an inclusive, supportive, kind and inspiring open source ecosystem as they seek to improve research culture, making it "open for all". Bio: Kirstie Whitaker leads the Tools, Practices and Systems Research Programme at The Alan Turing Institute (London, UK). The TPS community's mission is to invest in the people who sustain the open infrastructure ecosystem for data science. Kirstie is the lead developer of The Turing Way, an openly developed educational resource inspire, train and enable researchers and citizen scientists across government, industry, academia and third sector organisations to apply open source practices to their work. Kirstie is a passionate advocate for making science "open for all" by promoting equity and inclusion for people from diverse backgrounds, and by changing the academic incentive structure to reward collaborative working. She is the chair of the Turing Institute's Ethics Advisory Group, a Fulbright scholarship alumna and was a 2016/17 Mozilla Fellow for Science.

Optimal Spectral Initialization for Signal Recovery with Applications to Phase Retrieval

Publisher: name: arXiv
Year: 2018
Subjects: subject: Information Theory (cs.IT)

description: We present the optimal design of a spectral method widely used to initialize nonconvex optimization algorithms for solving phase retrieval and other signal recovery problems. Our work leverages recent results that provide an exact characterization of the performance of the spectral method in the high-dimensional limit. This characterization allows us to map the task of optimal design to a constrained optimization problem in a weighted $L^2$ function space. The latter has a closed-form solution. Interestingly, under a mild technical condition, our results show that there exists a fixed design that is uniformly optimal over all sampling ratios. Numerical simulations demonstrate the performance improvement brought by the proposed optimal design over existing constructions in the literature. In a recent work, Mondelli and Montanari have shown the existence of a weak reconstruction threshold below which the spectral method cannot provide useful estimates. Our results serve to complement that work by deriving the fundamental limit of the spectral method beyond the aforementioned threshold.

description: An attempt is made here to extend to the microscopic domain the scale invariant character of gravitation - which amounts to consider expansion as applying to any physical scale. Surprisingly, this hypothesis does not prevent the redshift from being obtained. It leads to strong restrictions concerning the choice between the presently available cosmological models and to new considerations about the notion of time. Moreover, there is no horizon problem and resorting to inflation is not necessary.

description: In-water ships’ hull cleaning enables significant fuel savings through removal of marine fouling from surfaces. However, cleaning may also shorten the lifetime of hull coatings, with a subsequent increase in the colonization and growth rate of fouling organisms. Deleterious effects of cleaning would be minimized by matching cleaning forces to the adhesion strength of the early stages of fouling, or microfouling. Calibrated waterjets are routinely used to compare different coatings in terms of the adhesion strength of microfouling. However, an absolute scale is lacking for translating such results into cleaning forces, which are of interest for the design and operation of hull cleaning devices. This paper discusses how such forces can be determined using computational fluid dynamics. Semi-empirical formulae are derived for forces under immersed waterjets, where the normal and tangential components of wall forces are given as functions of different flow parameters. Nozzle translation speed is identified as a parameter for future research, as this may affect cleaning efficacy.

description: The avian EB66® cell line, derived from duck embryonic stem cells, has been widely used for producing human and animal therapeutic proteins and vaccines. In current study we evaluated the potential use of EB66® cell line in a cell culture-derived duck Tembusu virus (DTMUV) vaccine development. After optimizing the growth conditions of DTMUV HB strain in EB66® cells, we successfully generated three batches of viruses with ELD50 titres of 105.9/0.1 ml, 105.3/0.1 ml and 105.5/0.1 ml, respectively, for using in the preparation of inactivated vaccines. The immunogenicity and protective efficacy of these EB66® cells-derived inactivated vaccines were examined in ducks. Results indicated that all three batches of vaccines induced haemagglutination-inhibition (HI) antibody response in immunized birds at 2 weeks after a single immunization. Immunized ducks and ducklings were protected against a virulent challenge at 4 weeks after a booster immunization. The duration of immunity was for 3–4 months after a booster immunization. These results demonstrated the feasibility of using EB66® cell line to grow up DTMUV for vaccine preparation.

description: On 30 Nov 2018, the ERAC received a mandate from the Council of the EU to produce options for a new narrative/paradigm on the future of the ERA, and to elaborate possible future ERA objectives and priorities. [1] In this context an ad-hoc ERAC working group has
 produced a first draft of “Options for a new ERA narrative” and the ERIC Forum has been consulted within the ERA Stakeholders platform. On 29th July 2019, members of the ERIC Forum attended the stakeholder consultation meeting organised by the ERAC working group on the first draft narrative. At that occasion, the ERIC Forum was invited to provide a written answer to the key questions related to the draft narrative, and to provide a broad commentary to the document. This written contribution is a response to the above invitation, based on a consultation of the ERIC Forum. Given the limited time available for this consultation, we have captured the broad consensus of the ERIC Forum, but individual ERICs may have slightly differing priorities and additional inputs to make. The ERIC Forum will further discuss on the documents proposed by the ERAC, being one of the main ERA Stakeholders.

description: We use 156 044 white dwarf candidates with $\geq5σ$ significant parallax measurements from the Gaia mission to measure the velocity dispersion of the Galactic disc; $(σ_U,σ_V,σ_W) = (30.8, 23.9, 20.0)$ km s$^{-1}$. We identify 142 objects that are inconsistent with disc membership at the $>5σ$ level. This is the largest sample of field halo white dwarfs identified to date. We perform a detailed model atmosphere analysis using optical and near-infrared photometry and parallaxes to constrain the mass and cooling age of each white dwarf. The white dwarf cooling ages of our targets range from 7 Myr for J1657+2056 to 10.3 Gyr for J1049-7400. The latter provides a firm lower limit of 10.3 Gyr for the age of the inner halo based on the well-understood physics of white dwarfs. Including the pre-white dwarf evolutionary lifetimes, and limiting our sample to the recently formed white dwarfs with cooling ages of $<500$ Myr, we estimate an age of $10.9 \pm 0.4$ Gyr (internal errors only) for the Galactic inner halo. The coolest white dwarfs in our sample also give similar results. For example, J1049-7400 has a total age of 10.9-11.1 Gyr. Our age measurements are consistent with other measurements of the age of the inner halo, including the white dwarf based measurements of the globular clusters M4, NGC 6397, and 47 Tuc.

Evaluating probabilistic programming languages for simulating quantum correlations

Year: 2018
Subjects: subject: Quantum Physics (quant-ph)

description: This article explores how probabilistic programming can be used to simulate quantum correlations in an EPR experimental setting. Probabilistic programs are based on standard probability which cannot produce quantum correlations. In order to address this limitation, a hypergraph formalism was programmed which both expresses the measurement contexts of the EPR experimental design as well as associated constraints. Four contemporary open source probabilistic programming frameworks were used to simulate an EPR experiment in order to shed light on their relative effectiveness from both qualitative and quantitative dimensions. We found that all four probabilistic languages successfully simulated quantum correlations. Detailed analysis revealed that no language was clearly superior across all dimensions, however, the comparison does highlight aspects that can be considered when using probabilistic programs to simulate experiments in quantum physics.

description: This project introduces Echoform, a multi-volume emotional architecture system designed for high-resolution self-regulation, ethical cognition, and immersive survival structuring. Developed through real-time affective immersion and iterative structural design, Echoform translates internal emotional sequences into scalable, replicable design protocols. The system spans lexicon creation, emotion-structured identity design, case-based recovery models, and a forward-facing ethical framework for resonance-based affective technology. It does not theorize emotion — it operationalizes it. This is not a therapeutic tool. It is an existential infrastructure. Echoform proposes a new blueprint for emotional cognition at the intersection of design, AI alignment, and post-traumatic self-engineering.

description: The observed absence of gravitational aberration requires that ``Newtonian'' gravity propagate at a speed $c_g>2\times10^{10}c$. By evaluating the gravitational effect of an accelerating mass, I show that aberration in general relativity is almost exactly canceled by velocity-dependent interactions, permitting $c_g=c$. This cancellation is dictated by conservation laws and the quadrupole nature of gravitational radiation.

description: Abstract

A standard cosmological model naturally describes a feature of our universe mathematically. Inflationary illustration is now an important part of the typical cosmological model as it describes the early stage of the universe. Also, scalar tensor theories of gravity play an important role in constructing a competent cosmological model naturally assumes a late-time rapid expansion. In this study, we introduced the characteristics of inflationary models, Einstein equation solutions for a conformally coupled scalar field, and the new idea of a cosmological model with a non-vanishing cosmological constant.

description: We study the stability of three-dimensional numerical evolutions of the Einstein equations, comparing the standard ADM formulation to variations on a family of formulations that separate out the conformal and traceless parts of the system. We develop an implementation of the conformal-traceless (CT) approach that has improved stability properties in evolving weak and strong gravitational fields, and for both vacuum and spacetimes with active coupling to matter sources. Cases studied include weak and strong gravitational wave packets, black holes, boson stars and neutron stars. We show under what conditions the CT approach gives better results in 3D numerical evolutions compared to the ADM formulation. In particular, we show that our implementation of the CT approach gives more long term stable evolutions than ADM in all the cases studied, but is less accurate in the short term for the range of resolutions used in our 3D simulations.

description: Phonon heat transport in mesoscopic systems is investigated using methods analogous to the Landauer description of electrical conductance. A "universal heat conductance" expression that depends on the properties of the conducting pathway only through the mode cutoff frequencies is derived. Corrections due to reflections at the junction between the thermal body and the conducting bridge are found to be small except at very low temperatures where only the lowest few bridge modes are excited. Various non-equilibrium phonon distributions are studied: a narrow band distribution leads to clear steps in the cooling curve, analogous to the quantized resistance values in narrow wires, but a thermal distribution is too broad to show such features.

description: Herein we firstly introduce a straightforward, scalable and technologically relevant strategy to manufacture charged porous polymer membranes (CPMs) in a controllable manner. The pore sizes and porous architectures of CPMs are well-controlled by rational choice of anions in poly(ionic liquid)s (PILs). Continuously, heteroatom-doped hierarchically porous carbon membrane (HCMs) can be readily fabricated via morphology-maintaining carbonization of as-prepared CPMs. These HCMs being as photothermal membranes exhibited excellent performance for solar seawater desalination, representing a promising strategy to construct advanced functional nanomaterials for portable water production technologies.

description: We calculate the charge susceptibility and the linear and differential conductances of a double quantum dot coupled to two metallic reservoirs both at equilibrium and when the system is driven away from equilibrium. This work is motivated by recent progress in the realization of solid state spin qubits. The calculations are performed by using the Keldysh nonequilibrium Green function technique. In the noninteracting case, we give the analytical expression for the electrical current and deduce from there the linear conductance as a function of the gate voltages applied to the dots, leading to a characteristic charge stability diagram. We determine the charge susceptibility which also exhibits peaks as a function of gate voltages. We show how the study can be extended to the case of an interacting quantum dot.

description: We present Monte Carlo simulations of semidilute solutions of long self-attracting chain polymers near their Ising type critical point. The polymers are modeled as monodisperse self-avoiding walks on the simple cubic lattice with attraction between non-bonded nearest neighbors. Chain lengths are up to N=2048, system sizes are up to $2^{21}$ lattice sites and $2.8\times 10^5$ monomers. These simulations used the recently introduced pruned-enriched Rosenbluth method which proved extremely efficient, together with a histogram method for estimating finite size corrections. Our most clear result is that chains at the critical point are Gaussian for large $N$, having end-to-end distances $R\sim\sqrt{N}$. Also the distance $T_Θ-T_c(N)$ (where $T_Θ= \lim_{N\to\infty} T_c(N)$) scales with the mean field exponent, $T_Θ-T_c(N)\sim 1/\sqrt{N}$. The critical density seems to scale with a non-trivial exponent similar to that observed in experiments. But we argue that this is due to large logarithmic corrections. These corrections are similar to the very large corrections to scaling seen in recent analyses of $Θ$-polymers, and qualitatively predicted by the field theoretic renormalization group. The only serious deviation from this simple global picture concerns the N-dependence of the order parameter amplitudes which disagrees with a minimalistic ansatz of de Gennes. But this might be due to problems with finite size scaling. We find that the finite size dependence of the density of states $P(E,n)$ (where $E$ is the total energy and $n$ is the number of chains) is slightly but significantly different from that proposed recently by several authors.

description: We study the dynamics of a generalized version of the famous Kuramoto-Sakaguchi coupled oscillator model. In the classic version of this system, all oscillators are governed by the same ODE, which depends on the order parameter of the oscillator configuration. The order parameter is the arithmetic mean of the configuration of complex oscillator phases, multiplied by some constant complex coupling factor. In the generalized model we consider, the order parameter is allowed to be any complex linear combination of the complex oscillator phases, so the oscillators are no longer necessarily weighted identically in the order parameter. This asymmetric version of the K-S model exhibits a much richer variety of steady-state dynamical behavior than the classic symmetric version; in addition to stable synchronized states, the system may possess multiple stable (N-1,1) states, in which all but one of the oscillators are in sync, as well as multiple families of neutrally stable asynchronous states or closed orbits, in which no two oscillators are in sync. We present an exhaustive description of the possible steady state dynamical behaviors; our classification depends on the complex coefficients that determine the order parameter. We use techniques from group theory and hyperbolic geometry to reduce the dynamic analysis to a 2D flow on the unit disc, which has geometric significance relative to the hyperbolic metric. The geometric-analytic techniques we develop can in turn be applied to study even more general versions of Kuramoto oscillator networks.

description: This paper presents a new algorithm for the fast, shared memory, multi-core computation of augmented contour trees on triangulations. In contrast to most existing parallel algorithms our technique computes augmented trees, enabling the full extent of contour tree based applications including data segmentation. Our approach completely revisits the traditional, sequential contour tree algorithm to re-formulate all the steps of the computation as a set of independent local tasks. This includes a new computation procedure based on Fibonacci heaps for the join and split trees, two intermediate data structures used to compute the contour tree, whose constructions are efficiently carried out concurrently thanks to the dynamic scheduling of task parallelism. We also introduce a new parallel algorithm for the combination of these two trees into the output global contour tree. Overall, this results in superior time performance in practice, both in sequential and in parallel thanks to the OpenMP task runtime. We report performance numbers that compare our approach to reference sequential and multi-threaded implementations for the computation of augmented merge and contour trees. These experiments demonstrate the run-time efficiency of our approach and its scalability on common workstations. We demonstrate the utility of our approach in data segmentation applications.

description: Το δώμα είναι το νέο έδαφος προς οικειοποίηση, όχι απαραίτητα όμως υπό τη μορφή προσθήκης κι’ άλλων ορόφων, αλλά με την έννοια της δημιουργίας καταστάσεων και ανθρωπίνων δραστηριοτήτων. Σύμφωνα με τον Π. Τουρνικιώτη η σημασία του δώματος περιλαμβάνει αυτό που καλούμε ανάταση, άνοιγμα, ανάδυση, περιλαμβάνει οτιδήποτε βρίσκεται ανάμεσα στη γη και στον ουρανό. Το κυρίαρχο θέμα της ερευνητικής διαδικασίας αφορά στη πόλη της Αθήνας, η οποία κατά τη διάρκεια του περασμένου αιώνα μετατράπηκε σε σύνολα πολυκατοικιών, στα οποία συγκεντρώνεται ο μισός πληθυσμός της χώρας. Ο τύπος της πολυκατοικίας έχει απορροφήσει όλο το δημόσιο χώρο της πόλης και τον έχει κατακερματίσει σε χιλιάδες μικροιδιοκτησίες. Από τα παραπάνω οδηγούμαστε στο εξής ερώτημα: πως γίνεται ενώ δεν υπάρχουν επαρκείς ελεύθεροι χώροι, μια μεγάλη επιφάνεια του δομημένου περιβάλλοντος να παραμένει ανεκμετάλλευτη! Και φυσικά μιλάμε για τα δώματα των πολυκατοικιών. Στο κείμενο της διάλεξης γίνετε ανάλυση των βασικών χαρακτηριστικών που συνθέτουν την εικόνα της Αθήνας με στόχο να απαντηθούν κάποια από τα παραπάνω ερωτήματα. Χαρακτηριστικά όπως το ‘συνεχές χαλί’ που σχηματίζουν τα δώματα των πολυκατοικιών, η μικρή κλίμακα των οικοδομικών τετραγώνων, ο συνεχής και ζωντανός δημόσιος χώρος μέσα και έξω από την Πολυκατοικία, η θέα πάνω από το αστικό τοπίο η άναρχη δόμηση κ.α.
description: Rooftop is a new ground for appropriation, not necessarily by the addition of new storeys, but by the creation of situations and human activities. According to P. Tournikiotis, the meaning of the rooftop consists of what is called anatasis , emergence, and generally whatever lays between earth and sky. The dominant issues of the researching procedure concerns the city of Athens, which during the previous century was transformed into a group of blocks of flats (polykatoikia) where half of the population of the country was accumulated. The type of the block has absorbed the public space of the city and has fragmented it into thousands of properties. Taking everything into consideration we are driven to the following question: despite the absence of sufficient free spaces, why does a big surface of the built environment remain unused? Of course it is the rooftops of the blocks that we are talking about. In the text discussed the basic characteristics that compose the picture of Athens, in order to find an answer for some of the aforementioned questions. Characteristics such as the “continuous carpet” that is composed by the rooftops of the blocks of flats, the small scale of the blocks, the continuous public space both inside and outside of the Block of flats, the view over the urban landscape, the anarchy etc.

description: Nonlinear optical responses to external electromagnetic field, characterized by second and higher order susceptibilities, play crucial roles in nonlinear optical devices and novel optoelectronics. Herein we present a quantum nonlinear ferroic optical Hall effect (QNFOHE) in multiferroics - a Hall-like direct photocurrent originated from the second order current response to intense electromagnetic field whose direction can be controlled by both internal ferroic orders and external light polarization. QNFOHE consists of two types of nonlinear photocurrent responses - shift current and circular photocurrent under linearly and circularly polarized light irradiation dominated by topological shift vector and Berry curvature, respectively. We elucidate the microscopic mechanism of QNFOHE in a representative class of 2D multiferroic materials using group theoretical analyses and first-principles electronic structure theory. The complex interplay of crystalline, permutation, gauge, and time reversal symmetries as well as inherent causality governs the symmetry properties of shift current and circular photocurrent. QNFOHE combined with rich ferroic degrees of freedom in multiferroic materials will open up a variety of new avenues for realizing tunable and configurable nonlinear optoelectronics etc.

description: The recently introduced Spatial Spectral Compressive Spectral Imager (SSCSI) has been proposed as an alternative to carry out spatial and spectral coding using a binary on-off coded aperture. In SSCSI, the pixel pitch size of the coded aperture, as well as its location with respect to the detector array, play a critical role in the quality of image reconstruction. In this paper, a rigorous discretization model for this architecture is developed, based on a light propagation analysis across the imager. The attainable spatial and spectral resolution, and the various parameters affecting them, is derived through this process. Much like the displacement of zoom lens components leads to higher spatial resolution of a scene, a shift of the coded aperture in the SSCSI in reference to the detector leads to higher spectral resolution. This allows the recovery of spectrally detailed datacubes by physically displacing the mask towards the spectral plane. To prove the underlying concepts, computer simulations and experimental data are presented in this paper.
