description: Motivated by the goal for high accuracy modeling of gravitational radiation emitted by isolated systems, recently, there has been renewed interest in the numerical solution of the hyperboloidal initial value problem for Einstein's field equations in which the outer boundary of the numerical grid is placed at null infinity. In this article, we numerically implement the tetrad-based approach presented in [J.M. Bardeen, O. Sarbach, and L.T. Buchman, Phys. Rev. D 83, 104045 (2011)] for a spherically symmetric, minimally coupled, self-gravitating scalar field. When this field is massless, the evolution system reduces to a regular, first-order symmetric hyperbolic system of equations for the conformally rescaled scalar field which is coupled to a set of singular elliptic constraints for the metric coefficients. We show how to solve this system based on a numerical finite-difference approximation, obtaining stable numerical evolutions for initial black hole configurations which are surrounded by a spherical shell of scalar field, part of which disperses to infinity and part of which is accreted by the black hole. As a non-trivial test, we study the tail decay of the scalar field along different curves, including one along the marginally trapped tube, one describing the world line of a timelike observer at a finite radius outside the horizon, and one corresponding to a generator of null infinity. Our results are in perfect agreement with the usual power-law decay discussed in previous work. This article also contains a detailed analysis for the asymptotic behavior and regularity of the lapse, conformal factor, extrinsic curvature and the Misner-Sharp mass function along constant mean curvature slices.

description: The minimum weight perfect matching (MWPM) decoder is the standard decoding strategy for quantum surface codes. However, it suffers a harsh decrease in performance when subjected to biased or non-identical quantum noise. In this work, we modify the conventional MWPM decoder so that it considers the biases, the non-uniformities and the relationship between $X$, $Y$ and $Z$ errors of the constituent qubits of a given surface code. Our modified approach, which we refer to as the recursive MWPM decoder, obtains an $18\%$ improvement in the probability threshold $p_{th}$ under depolarizing noise. We also obtain significant performance improvements when considering biased noise and independent non-identically distributed (i.ni.d.) error models derived from measurements performed on state-of-the-art quantum processors. In fact, when subjected to i.ni.d. noise, the recursive MWPM decoder yields a performance improvement of $105.5\%$ over the conventional MWPM strategy and, in some cases, it even surpasses the performance obtained over the well-known depolarizing channel.

description: The primary objective of this article is to study the energy condition bounds for spherical and hyperbolic wormholes in well-known $f(R,T)$ theory of gravity. For this purpose, we formulate the field equations for spherically and pseudospherically geometries using anisotropic matter and linear form of generic function $f(R,T)$. By imposing different conditions on radial and tangential pressures or by adopting some known choices for red shift and shape functions, we present the graphical analysis of energy conditions for both spherically and pseudospherically symmetric wormholes. It is seen that energy density for spherically symmetric wormhole is always positive for $λ>-4π$ and $λ<-8π$, while the energy conditions for radial pressure are negative at throat. Likewise, in case of pseudospherically symmetric wormhole, it is observed that energy density is always positive for negative $λ$, however conditions based on radial pressure may be positive or negative for the considered different cases.

description: High-harmonic generation is typically thought of as a sub-laser-cycle process, with the electron's excursion in the continuum lasting a fraction of the optical cycle. However, it was recently suggested that long-lived Rydberg states can play a particularly important role in atoms driven by the combination of the counter-rotating circularly polarized fundamental light field and its second harmonic. Here we report direct experimental evidence of long and stable Rydberg trajectories contributing to high-harmonic generation. We confirm their effect on the harmonic emission via Time-Dependent Schr{ö}dinger Equation simulations and track their dynamics inside the laser pulse using the spin-orbit evolution in the ionic core, utilizing the spin-orbit Larmor clock. Our observations contrast sharply with the general view that long-lived Rydberg orbits should generate negligible contribution to the macroscopic far-field high harmonic response of the medium. Indeed, we show how and why radiation from such states can lead to well collimated macroscopic signal in the far field.

description: The presented first-of-its-kind study effectively identifies and visualizes the second-by-second pattern differences in the physiological arousal of preschool-age children who do stutter (CWS) and who do not stutter (CWNS) while speaking perceptually fluently in two challenging conditions i.e speaking in stressful situations and narration. The first condition may affect children's speech due to high arousal; the latter introduces linguistic, cognitive, and communicative demands on speakers. We collected physiological parameters data from 70 children in the two target conditions. First, we adopt a novel modality-wise multiple-instance-learning (MI-MIL) approach to classify CWS vs. CWNS in different conditions effectively. The evaluation of this classifier addresses four critical research questions that align with state-of-the-art speech science studies' interests. Later, we leverage SHAP classifier interpretations to visualize the salient, fine-grain, and temporal physiological parameters unique to CWS at the population/group-level and personalized-level. While group-level identification of distinct patterns would enhance our understanding of stuttering etiology and development, the personalized-level identification would enable remote, continuous, and real-time assessment of stuttering children's physiological arousal, which may lead to personalized, just-in-time interventions, resulting in an improvement in speech fluency. The presented MI-MIL approach is novel, generalizable to different domains, and real-time executable. Finally, comprehensive evaluations are done on multiple datasets, presented framework, and several baselines that identified notable insights on CWSs' physiological arousal during speech production.

description: We study the localization and topological transitions of the generalized non-Hermitian SSH models, where the non-Hermiticities are introduced by the complex quasiperiodic hopping and the nonreciprocal hopping. We elucidate the universality of the models and how many models can be mapped to them. Under the open boundary condition, two delocalization transitions are found due to the competition between the Anderson localization and the boundary localization from the nontrivial edge states and the non-Hermitian skin effect. Under the periodic boundary condition, only one delocalization transition is found due to the disappearance of the non-Hermitian skin effect. The winding numbers of energy and the Lyapunov exponents in analytical form are obtained to exactly characterize the two deloaclizateon transitions. It finds that the delocalization transitions don't accompany the topological transition. Furthermore, the large on-site non-Hermiticity and the large nonreciprocal hopping are all detrimental to the topological transitions. However, the large nonreciprocal hopping enhances the Anderson localizations. The above analyses are verified by calculating the energy gap and the inverse of the participation ratio numerically.

First measurement of the inclusive Φ meson production cross-section in pp collisions at √s = 7 TeV and search for CP violation in the Bs→φφ decay at LHCb

description: Several studies towards the measurement of CP violation in the Bs0→ΦΦ decay channel with the LHCb experiment at the Large Hadron Collider at CERN are presented in this thesis. An important input to this analysis is precise knowledge of the detector performance and the Φ meson production in proton-proton collisions. As a study targeting both goals, the first measurement of the inclusive Φ meson production cross-section in pp collisions at a center-of-mass energy of √s = 7 TeV is carried out. The CP violating phase in the Bs0→ΦΦ decay is predicted to vanish in the Standard Model of particle physics, but it could adopt finite values in some models beyond the Standard Model. Hereby this phase can distinguish different models and be a direct hint of “New Physics” in the case that a non-vanishing phase is measured. The first step to an analysis of the Bs0→ΦΦ decay is the implementation of a signal pre-selection. The experimental techniques to extract the CP violating phase in this decay channel are developed and tested on samples simulated by event generators. Furthermore, the projective performance of the LHCb detector is determined from simulated samples and the signal and background yield expectation is extrapolated from data. Based on these analyses, the statistical uncertainty on the CP violating phase is predicted as 0.23 ± 0.04 for one nominal year (2 fb-1) of LHCb data taking. As premise for CP violation studies, the detector performance needs to be understood. Further, since simulated samples are part of the analysis process, good agreement between the predictions and the real data is necessary. The Φ meson production in pp collision is governed by the non-perturbative QCD regime, which event generators describe by phenomenological models that need to be tuned to data. The measurement of the inclusive Φ meson production cross-section is an important probe of strangeness production in the context of this tuning effort. The differential Φ meson production cross-section is determined as a function of the Φ transverse momentum pT and rapidity y in the region 0.6 < pT < 5.0 GeV/c and 2.44 < y < 4.06. The total Φ meson production cross-section in this range is σ(pp→ΦX) = 1758 ± 19(stat) +43/-14 (syst) ±182(syst) µb, where the first systematic uncertainty depends on the pT and y region and the second is related to the overall scale. Predictions based on the P YTHIA 6.4 generator underestimate the cross-section.
title: Making “heartware”: Statecraft and hegemony in Singapore’s welfare regime
Creators: name: Yeo, Yak
Publisher: name: University of Liverpool Repository
Year: 2027

description: This project presents a case study of state power and ideology as a cultural force in a neoliberal welfare regime. Utilising a cultural political economy (CPE) approach, I argue that sense-making processes of the welfare apparatus seek to constitute the dominant economic imaginary to produce subjects and sensibilities aligned to sustain capitalist social forms. I illuminate welfare sites as spaces through which capitalist logics are mediated, naturalised and embedded into everyday Singaporean life. Through an analysis of historical contingencies, material policy regulations and government communications, I interrogate state-led processes in the articulation of accumulation strategies and logics to implicate state power in the reproduction of capitalism.

Within Singapore, the semiosis and structuration of welfare depoliticises what are in reality highly political welfare relations for the reproduction of Singaporean life. The welfare regime veils the working of state power to legitimise deeply unequal social relations by naturalising racial relations, activating labour market relations and the embedding of the nuclear family. State-led depoliticisation constructs an ideological environment that presents the pursuance of capitalist ideals as a form of Singaporean subjectivity, restricting imaginings of alternative possibilities as the current accumulation regime is presented as good, natural and inevitable. I argue that this results in a post-political condition, where politics to contest the current regime is foreclosed. 

The welfare apparatus represents state bias and tendencies in their structuring and privileging of certain social processes and relations. Through mapping the dominant economic imaginary, which I describe as the heartware of Singapore, I identify three social forms that seek to organise welfare resources and regulate economic lives. Firstly, a racialised model of citizenship draws boundaries between deserving and underserving subjects across ethnicity and citizenship. Secondly, a commodified model of welfare structures economic productivity and pro-work values into Singaporean lives. Thirdly, the exaltation of the nuclear family privileges heteronormative relations while restricting alternative forms of solidarities to encourage specific forms of social reproduction. Each of these social forms highlight the state’s crisis tendency to secure economic growth while displacing contradictions of development onto staged problematisations. In mapping the dominant economic imaginary through an interrogation of Singaporean social policy, I critique state power in the privileging of certain social identities, practices and relations in the reproduction of capitalism. In applying CPE to Singapore, this thesis hopes to contribute towards a more critically minded social policy analysis within this specific locality.

description: This paper addresses the localization problem. The extended Kalman filter (EKF) is employed to localize a unicycle-like mobile robot equipped with a laser range finder (LRF) sensor and an omni-directional camera. The LRF is used to scan the environment which is described with line segments. The segments are extracted by a modified least square quadratic method in which a dynamic threshold is injected. The camera is employed to determine the robot's orientation. The prediction step of the EKF is performed by extracting parameters from the kinematic model and input signal of the robot. The correction step is conducted with the implementation of a line matching algorithm and the comparison between line's parameters of the local and global maps. In the line matching algorithm, a conversion matrix is introduced to reduce the computation cost. Experiments have been carried out in a real mobile robot system and the results prove the applicability of the method for the purpose of localization.

description: An aspirational goal for virtual reality (VR) is to bring in a rich diversity of real world objects losslessly. Existing VR applications often convert objects into explicit 3D models with meshes or point clouds, which allow fast interactive rendering but also severely limit its quality and the types of supported objects, fundamentally upper-bounding the "realism" of VR. Inspired by the classic "billboards" technique in gaming, we develop Deep Billboards that model 3D objects implicitly using neural networks, where only 2D image is rendered at a time based on the user's viewing direction. Our system, connecting a commercial VR headset with a server running neural rendering, allows real-time high-resolution simulation of detailed rigid objects, hairy objects, actuated dynamic objects and more in an interactive VR world, drastically narrowing the existing real-to-simulation (real2sim) gap. Additionally, we augment Deep Billboards with physical interaction capability, adapting classic billboards from screen-based games to immersive VR. At our pavilion, the visitors can use our off-the-shelf setup for quickly capturing their favorite objects, and within minutes, experience them in an immersive and interactive VR world with minimal loss of reality.

Year: 2019

description: Banking is one of the service sectors where competition is stiff to attract new or retain the existing customers among commercial banks. Customer relationship marketing is one of the strategies whereby banks are using to be competitive in financial sector. Customer relationship marketing helps banks to retain customers as the practice of CRM pays attention to the need of individual customers and eventually contributes a lot to customer loyalty. The objective of this study was to examine the effect of customer relationship marketing on customer loyalty in CBE in the case of Burayu branches. The researcher used the behavioral components of CRM i.e. Trust, customer perceived value, Commitment, conflict handling and empathy as independent variables to examine its effect on loyalty. The researcher used descriptive and explanatory research design to meet the research objectives. The researcher used convenient sampling method to get representative sample from the populations. The researcher collected data from two branches of CBE through structured questionnaire to assess customers' level of agreement regarding Customer relationship marketing practice in their respective banks. A total of 384 questionnaires were distributed to collect data and out of the total 320 questionnaires were returned. The collected data was analyzed using statistical package for social science (SPSS) version 20.The descriptive statistics (mean, standard deviation) and inferential statistics (correlation and regression) were used to described demographic facts, to test hypothesis and to answer research questions. The statistical result showed that Customer relationship marketing which is represented by five behavioral components has a positive and significant influence on customer loyalty. The researcher suggested that CBE has to pay attention to Customer perceived value dimension as it has highest influence on customer loyalty.

description: Resolutions of certain toroidal orbifolds, like T6/Z2xZ2, are far from unique, due to triangulation dependence of their resolved local singularities. This leads to an explosion of the number of topologically distinct smooth geometries associated to a single orbifold. By introducing a parameterisation to keep track of the triangulations used at all resolved singularities simultaneously, (self-)intersection numbers and integrated Chern classes can be determined for any triangulation configuration. Using this method the consistency conditions of line bundle models and the resulting chiral spectra can be worked out for any choice of triangulation. Moreover, by superimposing the Bianchi identities for all triangulation options much simpler though stronger conditions are uncovered. When these are satisfied, flop--transitions between all different triangulations are admissible. Various methods are exemplified by a number of concrete models on resolutions of the T6/Z2xZ2 orbifold.

description: Medulloblastomas (MB) are malignant embryonic neuroepithelial tumors of the cerebellum, accounting Medulloblastomas, predominant childhood tumors, account for a substantial portion of Central Nervous System neoplasms in the first decade of life. Originating from embryonic and undifferentiated neuroepithelial cells within the cerebellum, particularly the cerebellar vermis, these tumors are intricately linked to the external granular layers of the cerebellar hemispheres (Millard and De Braganca, 2016; Valtz et al., 1991). This research aims to elucidate the unique manifestation of medulloblastoma in the cerebellopontine angle (CPA), an uncommon occurrence with sparse documentation in the literature, primarily observed in the adult population.

The embryological association of medulloblastomas with the external granular layers of the cerebellum and germinal cell remnants in the posterior medullary velum provides a foundation for understanding their prevalence in pediatric cases (Millard and De Braganca, 2016; Valtz et al., 1991). Proper classification of these tumors stems from their origin in embryonic and undifferentiated neuroepithelial cells, accentuating their affiliation with the cerebellar vermis (Rutka and Hoffman, 1991; Jakacki, 2005; Gajjar et al., 2004).

In contrast, medulloblastoma occurrences in the cerebellopontine angle are infrequent, with limited documented cases primarily observed in the adult demographic, constituting up to 75% of cases within this age group (Noiphithak et al., 2016; Faried et al., 2016). Notably, adult medulloblastomas in the CPA display distinctive characteristics, predominantly lateral localization in the cerebellar hemispheres, axial positioning, cystic formations, and ill-defined margins, often extending to the fourth ventricular foramen (Taylor et al., 2012; Helseth et al., 1999; Savardekar et al., 2012).

This research endeavors to contribute to the limited body of knowledge on medulloblastomas in the cerebellopontine angle, providing insights into the unique features and challenges associated with this rare manifestation in the adult population.

description: Many complex molecular systems owe their properties to local dynamic rearrangements or fluctuations that, despite the rise of machine learning (ML) and sophisticated structural descriptors, remain often difficult to detect. Here we show an ML framework based on a new descriptor, named Local Environments and Neighbors Shuffling (LENS), which allows identifying dynamic domains and detecting local fluctuations in a variety of systems via tracking how much the surrounding of each molecular unit changes over time in terms of neighbor individuals. Statistical analysis of the LENS time-series data allows to blindly detect different dynamic domains within various types of molecular systems with, e.g., liquid-like, solid-like, or diverse dynamics, and to track local fluctuations emerging within them in an efficient way. The approach is found robust, versatile, and, given the abstract definition of the LENS descriptor, capable of shedding light on the dynamic complexity of a variety of (not necessarily molecular) systems.

description: We consider spatially localized spiking activity patterns, so-called bumps, in ensembles of bistable spiking oscillators. The bistability consists in the coexistence of self-sustained spiking dynamics and quiescent steady-state regime. We show numerically that the processes of growth or contraction of such patterns can be controlled by varying the intensity of multiplicative noise. In particular, the effect of the noise is monotonic in an ensemble of the coupled Hindmarsh-Rose oscillators. On the other hand, in another model proposed by V. Semenov et al. in 2016 (see Ref. [V. Semenov et al., Phys. Rev. E 93, 052210 (2016)]), a resonant noise effect is observed. In that model, stabilization of the activity bump expansion is achieved at an appropriate noise level, and the noise effect reverses with a further increase in noise intensity. Moreover, we show the constructive role of nonlocal coupling which allows to save domains and fronts being totally destroyed due to the action of noise in the case of local coupling.

description: With the unprecedented success of transformer networks in natural language processing (NLP), recently, they have been successfully adapted to areas like computer vision, generative adversarial networks (GAN), and reinforcement learning. Classifying electroencephalogram (EEG) data has been challenging and researchers have been overly dependent on pre-processing and hand-crafted feature extraction. Despite having achieved automated feature extraction in several other domains, deep learning has not yet been accomplished for EEG. In this paper, the efficacy of the transformer network for the classification of raw EEG data (cleaned and pre-processed) is explored. The performance of transformer networks was evaluated on a local (age and gender data) and a public dataset (STEW). First, a classifier using a transformer network is built to classify the age and gender of a person with raw resting-state EEG data. Second, the classifier is tuned for mental workload classification with open access raw multi-tasking mental workload EEG data (STEW). The network achieves an accuracy comparable to state-of-the-art accuracy on both the local (Age and Gender dataset; 94.53% (gender) and 87.79% (age)) and the public (STEW dataset; 95.28% (two workload levels) and 88.72% (three workload levels)) dataset. The accuracy values have been achieved using raw EEG data without feature extraction. Results indicate that the transformer-based deep learning models can successfully abate the need for heavy feature-extraction of EEG data for successful classification.

description: The classical derivation of the well-known Vasicek model for interest rates is reformulated in terms of the associated pricing kernel. An advantage of the pricing kernel method is that it allows one to generalize the construction to the Lévy-Vasicek case, avoiding issues of market incompleteness. In the Lévy-Vasicek model the short rate is taken in the real-world measure to be a mean-reverting process with a general one-dimensional Lévy driver admitting exponential moments. Expressions are obtained for the Lévy-Vasicek bond prices and interest rates, along with a formula for the return on a unit investment in the long bond, defined by $L_t = \lim_{T \rightarrow \infty} P_{tT} / P_{0T}$, where $P_{tT}$ is the price at time $t$ of a $T$-maturity discount bond. We show that the pricing kernel of a Lévy-Vasicek model is uniformly integrable if and only if the long rate of interest is strictly positive.

description: Depending on deformed canonical anti-commutation relations, massless neutrino oscillation based on Lorentz invariance violation in non-commutative field theory is discussed. It is found that the previous studies about massless neutrino oscillation within deformed canonical anti-commutation relations should satisfy the condition of new Moyal product and new non standard commutation relations. Furthermore, comparing the Lorentz Invariant Violation parameters $\mathit{A}$ in the previous studies with new Moyal product and new non standard commutation relations, we find that the orders of magnitude of non-commutative parameters (Lorentz invariant Violation parameters $\mathit{A}$) is not self-consistent. This inconsistency means that the previous studies of Lorentz invariance violation in non-commutative field theory may not naturally explain massless neutrino oscillation. In other words, it should be impossible to explain neutrino oscillation by Lorentz invariance violation in non-commutative field theory. This conclusion is supported by the latest atmospheric neutrinos experimental results from the Super-Kamiokande Collaboration, which show that no evidence of Lorentz invariance violation on atmospheric neutrinos was observed.

description: Variational algorithms have received significant attention in recent years due to their potential to solve practical problems using noisy intermediate-scale quantum (NISQ) devices. A fundamental step of these algorithms is the evaluation of the expected value of Hamiltonians, and hence efficient schemes to perform this task are required. The standard approach employs local measurements of Pauli operators and requires a large number of circuits. An alternative is to make use of entangled measurements, which might introduce additional gates between physically disconnected qubits that harm the performance. As a solution to this problem, we propose hardware-efficient entangled measurements (HEEM), that is, measurements that permit only entanglement between physically connected qubits. We show that this strategy enhances the evaluation of molecular Hamiltonians in NISQ devices by reducing the number of circuits required without increasing their depth. We provide quantitative metrics of how this approach offers better results than local measurements and arbitrarily entangled measurements. We estimate the ground-state energy of the H$_2$O molecule with classical simulators and quantum hardware using the variational quantum eigensolver with HEEM.

description: The geometrical structure and photoexcitation properties of Zn27-nCdnO27C42 complexes are investigated by density functional theory (DFT) and time-dependent DFT calculations at the PBE0/6-31G*/SDD level of theory. The cohesive energy and frequency analysis indicate that the hybrid materials are energetically stable. In presence of Cd substituting atoms, energy gap of the ZnO nanodots surrounded by carbon moiety is shown to decrease, as compared to Cd-free complex. In-depth excited state analysis including charge density difference (CDD) mapping and absorption spectrum decomposition is performed to reveal the nature of the dominant excited states and to comprehend the Cd-to-Zn substitution effect on the photoexcitation properties of Zn27-nCdnO27C42. A principal possibility to enhance intramolecular charge transfer through incorporation of certain number of Cd atoms into the ZnO nanodots is shown. Such Cd-induced modifications in optical properties of semi-spherical Zn27-nCdnO27C42 complexes could potentially enable use of this hybrid material in optoelectronic and photocatalytic applications.

description: The aim of this thesis is to assess the Leadership Career Aspiration among Female Postgraduate students in the case of Addis Ababa University. The study adopting quantitative research techniques answers two basic research questions, first how does self-esteem of females related to their leadership aspiration. Second, Does Organization identification of females" shape their career development .The Study was conducted with female graduate students of Addis Ababa University registered during the 2018/19 academic year in the regular program. Results of this study provided support for the reliability and validity of the Leadership Career Aspiration with postgraduate women. The results from confirmatory factor analyses indicated that the three-factor solution had good model fit, thus supporting a revised measure with three subscales assessing, Organization Identification, Self-esteem and leadership aspirations. To test this factor structure, a confirmatory factor analysis was conducted. The research also hypothesized that score on the Career Aspiration subscales would correlate positively with and self-esteem negatively with willingness to compromise career for Leadership. The target population comprised 367 and 338 samples collected. The study used questionnaires as a tool for data collection. In order to test the reliability of the instrument, the Crobanch alpha test was used. Pearson correlation and multiple linear regression analysis were Leadership aspiration to estimate the causal relationships between Organization Identification and Self-esteem. Finally, the presented results depict an important step toward understanding how organizational identification and self-esteem interact and how they interact with women"s leadership aspiration. The study recommends that Formal institutional change is important to counter gendered social norms and whether building their self-esteem and confidence or reframing their body image, recognize the social messages and cultural norms you are contesting.

description: The generalized $H(n)$ Hirsch index of order $n$ has been recently introduced and shown to interpolate between the degree and the $K$-core centrality in networks. We provide a detailed analytical characterization of the properties of sets of nodes having the same $H(n)$, within the annealed network approximation. The connection between the Hirsch indices and the degree is highlighted. Numerical tests in synthetic uncorrelated networks and real-world correlated ones validate the findings. We also test the use of the Hirsch index for the identification of influential spreaders in networks, finding that it is in general outperformed by the recently introduced Non-Backtracking centrality.

description: Interaction effects capture the impact of one explanatory variable x1 on the marginal effect of another explanatory variable x2. To explore interaction effects, socalled interaction terms x1x2 are typically included in estimation specifications. While in linear models the effect of a marginal change in the interaction term is equal to the interaction effect, this equality generally does not hold in non-linear specifications (AI,NORTON, 2003). This paper provides for a general derivation of interaction effects in both linear and non-linear models and calculates the formulae of the interaction effects resulting from HECKMAN’s sample selection model as well as the Two-Part Model, two regression models commonly applied to data with a large fraction of either missing or zero values in the dependent variable, respectively. Drawing on a survey of automobile use from Germany, we argue that while it is important to test for the significance of interaction effects, their size conveys limited substantive content. More meaningful, and also more easy to grasp, are the conditional marginal effects pertaining to two variables that are assumed to interact.

description: Resolving a problem of Conlon, Fox, and Rödl, we construct a family of hypergraphs with arbitrarily large tower height separation between their $2$-colour and $q$-colour Ramsey numbers. The main lemma underlying this construction is a new variant of the Erdős--Hajnal stepping-up lemma for a generalized Ramsey number $r_k(t;q,p)$, which we define as the smallest integer $n$ such that every $q$-colouring of the $k$-sets on $n$ vertices contains a set of $t$ vertices spanning fewer than $p$ colours. Our results provide the first tower-type lower bounds on these numbers.

description: Coherence, discord and geometric measure of entanglement are important tools for measuring physical resources. We compute them at every steps of the Grover's algorithm. We summarize these resources's patterns of change. These resources are getting smaller at the step oracle and are getting bigger or invariant at the step diffuser. This result is similar to the entanglement's pattern of change in Grover's algorithm. Furthermore, we compute GM at every steps of the Harrow-Hassidim-Lloyd algorithm.
