Sensitively SMASHED! : effects of acute alcohol intoxication on a serious go/no-go inhibitory control task
Creators: name: Radke, SE
Publisher: name: University of Tasmania
Year: 2024

description: Inhibitory control is a key deficit of many individuals with a substance use disorder and has become a measure of interest for predicting treatment outcomes. However, traditional measures of inhibitory control have been deemed monotonous and unappealing. We have developed a brief computerised inhibitory control task - SMASHED! - using a serious game approach which could potentially be used as an engaging clinical assessment tool. It utilises the go/no-go paradigm with 'go'stimuli being healthy bottles and 'no-go' stimuli being alcoholic bottles. This within-subjects, single-blind, seven-day test-retest, double-dosing study was designed to validate SMASHED! and determine its sensitivity to acute alcohol intoxication (BrAC=.050%, .080%) using a healthy adult population (N=36; 61% female). SMASHED! demonstrated trivial to moderate magnitude correlations with a traditional inhibitory control task, possibly due to ceiling effects. Minimal learning effects were apparent on seven-day retest. SMASHED! demonstrated sensitivity to acute alcohol intoxication with significant, dose-dependent increases in participant reaction time. Gamified elements made SMASHED! engaging and enjoyable for participants but potentially contributed to participants altering their task approach. Further development of SMASHED! is necessary to ensure it is a valid and sensitive measure of inhibitory control and reduce ceiling effects.

Explicit construction of Hamiltonians with such property is presented in the framework of the interacting boson model (IBM), including higher order terms, and in its proton-neutron extension (IBM-2). The cases considered include a single prolate-deformed shape with solvable ground and $γ$ or $β$ bands, coexisting prolate-oblate shapes with solvable ground bands, and aligned axially-deformed proton-neutron shapes with solvable symmetric ground and $γ$ bands and mixed-symmetry scissors and $γ$ bands.

subject: FOS: Computer and information sciences

description: Synthetic indices are used in Economics to measure various aspects of monetary inequalities. These scalar indices take as input the distribution over a finite population, for example the population of a specific country. In this article we consider the case of the French 2004 Wealth survey. We have at hand a partial measurement on the distribution of interest consisting of bracketed and sometimes missing data, over a subsample of the population of interest. We present in this article the statistical methodology used to obtain point and interval estimates taking into account the various uncertainties. The inequality indices being nonlinear in the input distribution, we rely on a simulation based approach where the model for the wealth per household is multivariate. Using the survey data as well as matched auxiliary tax declarations data, we have at hand a quite intricate non-rectangle multidimensional censoring. For practical issues we use a Bayesian approach. Inference using Monte-Carlo approximations relies on a Monte-Carlo Markov chain algorithm namely the Gibbs sampler. The quantities interesting to the decision maker are taken to be the various inequality indices for the French population. Their distribution conditional on the data of the subsample are assumed to be normal centered on the design-based estimates with variance computed through linearization and taking into account the sample design and total nonresponse. Exogeneous selection of the subsample, in particular the nonresponse mechanism, is assumed and we condition on the adequate covariates.

description: A crucial ingredient in the recent discovery by Ablowitz, Halburd, Herbst and Korhonen \cite{AHH}, \cite {HK-2} that a connection exists between discrete Painlevé equations and (finite order) Nevanlinna theory is an estimate of the integrated average of $\log^+|f(z+1)/f(z)|$ on $|z|=r$. We obtained essentially the same estimate in our previous paper \cite{CF} independent of Halburd et al \cite{HK-1}. We continue our study in this paper by establishing complete asymptotic relations amongst the logarithmic differences, difference quotients and logarithmic derivatives for finite order meromorphic functions. In addition to the potential applications of our new estimates in integrable systems, they are also of independent interest. In particular, our findings show that there are marked differences between the growth of meromorphic functions with Nevanlinna order smaller and greater than one. We have established a "difference" analogue of the classical Wiman-Valiron type estimates for meromorphic functions with order less than one, which allow us to prove all entire solutions of linear difference equations (with polynomial coefficients) of order less than one must have positive rational order of growth. We have also established that any entire solution to a first order algebraic difference equation (with polynomial coefficients) must have a positive order of growth, which is a "difference" analogue of a classical result of Pólya.

description: Microscopic presolar grains extracted from primitive meteorites have extremely anomalous isotopic compositions revealing the stellar origin of these grains. The composition of presolar spinel grain OC2 is different from that of all other presolar spinel grains. Large excesses of the heavy Mg isotopes are present and thus an origin from an intermediate-mass (IM) asymptotic giant branch (AGB) star was previously proposed for this grain. We discuss the isotopic compositions of presolar spinel grain OC2 and compare them to theoretical predictions. We show that the isotopic composition of O, Mg and Al in OC2 could be the signature of an AGB star of IM and metallicity close to solar experiencing hot bottom burning, or of an AGB star of low mass (LM) and low metallicity suffering very efficient cool bottom processing. Large measurement uncertainty in the Fe isotopic composition prevents us from discriminating which model better represents the parent star of OC2. However, the Cr isotopic composition of the grain favors an origin in an IM-AGB star of metallicity close to solar. Our IM-AGB models produce a self-consistent solution to match the composition of OC2 within the uncertainties related to reaction rates. Within this solution we predict that the 16O(p,g)17F and the 17O(p,a)14N reaction rates should be close to their lower and upper limits, respectively. By finding more grains like OC2 and by precisely measuring their Fe and Cr isotopic compositions, it may be possible in the future to derive constraints on massive AGB models from the study of presolar grains.

description: Classical $(1+1)D$ cellular automata, as for instance Domany-Kinzel cellular automata, are paradigmatic systems for the study of non-equilibrium phenomena. Such systems evolve in discrete time-steps, and are thus free of time-discretisation errors. Moreover, information about critical phenomena can be obtained by simulating the evolution of an initial seed that, at any finite time, has support only on a finite light-cone. This allows for essentially numerically exact simulations, free of finite-size errors or boundary effects. Here, we show how similar advantages can be gained in the quantum regime: The many-body critical dynamics occurring in $(1+1)D$ quantum cellular automata with an absorbing state can be studied directly on an infinite lattice when starting from seed initial conditions. This can be achieved efficiently by simulating the dynamics of an associated one-dimensional, non-unitary quantum cellular automaton using tensor networks. We apply our method to a model introduced recently and find accurate values for universal exponents, suggesting that this approach can be a powerful tool for precisely classifying non-equilibrium universal physics in quantum systems.

description: A chiral bobber is a localized three-dimensional magnetization configuration, terminated by a singularity. Chiral bobbers coexist with magnetic skyrmions in chiral magnets, lending themselves to new types of skyrmion-complementary bits of information. However, the on-demand creation of bobbers, as well as their direct observation remained elusive. Here, we introduce a new mechanism for creating a stable chiral bobber lattice state via the proximity of two skyrmion species with comparable size. This effect is experimentally demonstrated in a Cu$_2$OSeO$_3$/[Ta/CoFeB/MgO]$_4$ heterostructure in which an exotic bobber lattice state emerges in the phase diagram of Cu$_2$OSeO$_3$. To unambiguously reveal the existence of the chiral bobber lattice state, we have developed a novel characterization technique, magnetic truncation rod analysis, which is based on resonant elastic x-ray scattering.

description: Prediction of stock prices has been an important area of research for a long time. While supporters of the efficient market hypothesis believe that it is impossible to predict stock prices accurately, there are formal propositions demonstrating that accurate modeling and designing of appropriate variables may lead to models using which stock prices and stock price movement patterns can be very accurately predicted. In this work, we propose an approach of hybrid modeling for stock price prediction building different machine learning and deep learning-based models. For the purpose of our study, we have used NIFTY 50 index values of the National Stock Exchange (NSE) of India, during the period December 29, 2014 till July 31, 2020. We have built eight regression models using the training data that consisted of NIFTY 50 index records during December 29, 2014 till December 28, 2018. Using these regression models, we predicted the open values of NIFTY 50 for the period December 31, 2018 till July 31, 2020. We, then, augment the predictive power of our forecasting framework by building four deep learning-based regression models using long-and short-term memory (LSTM) networks with a novel approach of walk-forward validation. We exploit the power of LSTM regression models in forecasting the future NIFTY 50 open values using four different models that differ in their architecture and in the structure of their input data. Extensive results are presented on various metrics for the all the regression models. The results clearly indicate that the LSTM-based univariate model that uses one-week prior data as input for predicting the next week open value of the NIFTY 50 time series is the most accurate model.

description: The purpose of this study is to determine whether a traditional school academic model and a non-traditional academic model are equally effective in leading students in a low income, urban high school to meet graduation requirements. The study used a causal-comparative design with a convenience sample to compare graduation rates of seniors who followed a traditional academic model and those who followed a non-traditional academic model. A chi-square test was used to compare the proportion of traditional and non-traditional students that met graduation requirements. The null hypothesis indicated that in a year in which some seniors participated in a traditional academic model and other seniors participated in a non-traditional academic model, there would be no significant difference in the proportion of students that graduated. The null hypothesis failed to be rejected. Research revealed that both traditional and non-traditional academic models provide a notable means of success for students.

For flat knots and links the two sides of the relation equation are put equal to unity and the algebra becomes the Weyl algebra. If this is perturbed and the two sides of the relation equation are put equal to a general element, $q$, of the ground ring, then the resulting module lays claim to be the correct generalization of the Alexander module. Many finite dimensional representations are given together with calculations.

description: Enhanced optical absorption in two-dimensional (2D) materials has recently moved into the focus of nanophotonics research. In this work, we present a gain-assisted method to achieve critical coupling and demonstrate the maximum absorption in undoped monolayer graphene in the near-infrared. In a two-port system composed of photonic crystal slab loaded with graphene, the gain medium is introduced to adjust the dissipative rate to match the radiation rate for the critical coupling, which is accessible without changing the original structural geometry. The appropriate tuning of the gain coefficient also enables the critical coupling absorption within a wide wavelength regime for different coupling configurations. This work provides a powerful guide to manipulate light-matter interaction in 2D materials and opens up a new path to design ultra-compact and high-performance 2D material optical devices.

description: The purpose of this study was to analyse contemporary performance data in elite and sub-elite Irish swimmers, to explore the number of days and races required for swimmers to achieve their fastest competitive performances and how this may be influenced by sex, stroke and race distance. The initial dataset consisted of n=3930 observations on n=56 swimmers, with n1=2709 (68.9%) long course (LC) observations and n2=1221 (31.1%) short course (SC) observations. The main findings indicated that, firstly, the swimmers (LC & SC) produced their fastest swim in their first race of the season, approximately 39% of the time. Secondly, there were no significant differences between male and female swimmers regarding the number of days and races required to achieve their fastest performances. The final key finding identified the number of days and races between first and fastest performance was influenced by (a) stroke, for example, LC and SC freestyle and individual medley swimmers required less races and shorter timeframes to fastest swim, with breaststroke requiring the greatest number of mean days in LC and SC formats and (b) race distance, for example, across LC and SC, 400 m swimmers required fewer races (n =1.83 & 1.64) and shorter time frame (n =24.83 & 21.26 days) to fastest swim than other distances. These findings are valuable to coaches and practitioners, as (a) they can provide guide-lines when designing competition programmes, and (b) support exploration of what a swimmer’s competition may look like in terms of volume and duration to support the fastest performance.

description: In many systems, the time scales of the microscopic dynamics and macroscopic dynamics of interest are separated by many orders of magnitude. Examples abound, for instance nucleation, protein folding, and chemical reactions. For these systems, direct simulation of phase space trajectories does not efficiently determine most physical quantities of interest. The last decade has seen the advent of methods circumventing brute force simulation. For most dynamical quantities, these methods all share the drawback of systematical errors. We present a novel method for generating ensembles of phase space trajectories. By sampling small pieces of these trajectories in different phase space domains and piecing them together in a smart way using equilibrium properties, we obtain physical quantities such as transition times. This method does not have any systematic error and is very efficient; the computational effort to calculate the first passage time across a free energy barrier does not increase with the height of the barrier. The strength of the method is shown in the Ising model. Accurate measurements of nucleation times span almost ten orders of magnitude and reveal corrections to classical nucleation theory.

description: For addressing optimisation tasks on finite dimensional quantum systems, we give a comprehensive account of the foundations of gradient flows on Riemannian manifolds including new developments: we extend former results from Lie groups such as the full unitary group to closed subgroups like partitionings by factorisation into tensor products, where the finest partitioning consists of purely local unitary operations. Moreover, the common framework is kept sufficiently general and allows for setting up gradient flows on (sub-)manifolds, Lie (sub-)groups, quotient groups, and reductive homogeneous spaces. Relevant convergence conditions are discussed meant to serve as justification for recent and new achievements, and as foundation for further research. Exploiting the differential geometry of quantum dynamics under different scenarios helps to provide highly useful algorithms: (a) On an abstract level, gradient flows may establish the exact upper bounds of pertinent quality functions, i.e. upper bounds reachable within the underlying manifold of the state space dynamics; (b) in a second stage referring to a concrete experimental setting, gradient flows on the manifold of piecewise constant control amplitudes $\R^m$ may be set up to provide (approximations to) optimal control of quantum devices under realistic conditions. Illustrative examples and new applications are given relating to distance measures of pure-state entanglement. We establish the correspondence to best rank-1 approximations of higher-order tensors.

Explaining Black-box Models for Biomedical Text Classification

Year: 2020
Subjects: subject: Artificial Intelligence (cs.AI)
subject: FOS: Computer and information sciences

description: In this paper, we propose a novel method named Biomedical Confident Itemsets Explanation (BioCIE), aiming at post-hoc explanation of black-box machine learning models for biomedical text classification. Using sources of domain knowledge and a confident itemset mining method, BioCIE discretizes the decision space of a black-box into smaller subspaces and extracts semantic relationships between the input text and class labels in different subspaces. Confident itemsets discover how biomedical concepts are related to class labels in the black-box's decision space. BioCIE uses the itemsets to approximate the black-box's behavior for individual predictions. Optimizing fidelity, interpretability, and coverage measures, BioCIE produces class-wise explanations that represent decision boundaries of the black-box. Results of evaluations on various biomedical text classification tasks and black-box models demonstrated that BioCIE can outperform perturbation-based and decision set methods in terms of producing concise, accurate, and interpretable explanations. BioCIE improved the fidelity of instance-wise and class-wise explanations by 11.6% and 7.5%, respectively. It also improved the interpretability of explanations by 8%. BioCIE can be effectively used to explain how a black-box biomedical text classification model semantically relates input texts to class labels.

Subjects: subject: LA-ICP-MS

subject: diffusion profiles

description: Materials based on polyimide show a wide range of use in electrical engineering, for example as isolation and protection medium. Nevertheless, ions can penetrate such layers, which leads to corrosion and to deterioration of the system. Consequently, it is important to understand the interaction between ions and polymer layers.In this project, polyimide layers were produced, and their thicknesses determined. Subsequently, these layers were integrated into a diffusion cell. In this cell, the polymer was used as a separator for two different concentrated salt solutions. The diffusion leaded to a reduction of potential difference, which can be measured. Furthermore, a Laser Ablation Induced Coupled Plasma Mass Spectrometer (LA ICP MS) was used to examine diffusion profiles and elemental distributions on the surface of these layers.During this project, a new method for determining layer thicknesses and for producing more homogeneous polyimide layers were implemented. Also, Nafion® membranes were used to examine the difference when switching from a ionic highly impervious barrier to a more permeable one and to identify the osmotic impact on layers. Using polyimide P84® layers, no reproducible diffusion trend curves were obtained, despite of several optimisations. Nevertheless, most of the sources of error could be located for further improvement measures. By using LA ICP MS, conclusions about diffusion and their inhomogeneous localities were evaluated.In conclusion, several statements and propositions about mechanics of ionic diffusion using Nafion® and polyimide layers were made. For higher quality, used polyimide layer should be produced industrially. Additionally, a new method should be implemented, to fix penetrated layers on a substrate for the ablation process. The obtained results can be used for comparison with diffusion simulations and further analyses for determining diffusion mechanics in polymers.

description: Die vierjährige
      Transformationsphase nach dem Sturz des ägyptischen
      Präsidenten Mubarak erlebte den schnellen Aufstieg und ebenso
      rasanten Fall der ägyptischen Muslimbruderschaft. Aus den
      ersten Ende 2011 abgehaltenen freien Parlamentswahlen ging
      die von ihr gegründete Freedom and Justice Party (FJP) mit
      37% der Stimmen als stärkste Kraft hervor. Auch die
      Senatswahlen im darauffolgenden Jahr konnte die FJP für sich
      entscheiden. Bei der Präsidentschaftswahl im Juni 2012
      erlangte mit Muhammed Mursi erstmals ein Muslimbruder in
      einem arabischen Land das höchste Staatsamt. Die 1928
      gegründete Muslimbruderschaft war stärker als jede andere
      Kraft in der ägyptischen Gesellschaft verwurzelt und verfügte
      über ein breites Netz sozialer Institutionen. Während andere
      Parteien überwiegend in den großen urbanen Zentren aktiv
      waren, waren die Muslimbrüder unter allen Schichten und in
      allen geographischen Regionen präsent.

description: Noble metal nanostructures are ubiquitous elements in nano-optics, supporting plasmon modes that can focus light down to length scales commensurate with nonlocal effects associated with quantum confinement and spatial dispersion in the underlying electron gas. Nonlocal effects are naturally more prominent for crystalline noble metals, which potentially offer lower intrinsic loss than their amorphous counterparts, and with particular crystal facets giving rise to distinct electronic surface states. Here, we employ a quantum-mechanical model to describe nonclassical effects impacting the optical response of crystalline noble-metal films and demonstrate that these can be well-captured using a set of surface-response functions known as Feibelman $d$-parameters. In particular, we characterize the $d$-parameters associated with the (111) and (100) crystal facets of gold, silver, and copper, emphasizing the importance of surface effects arising due to electron wave function spill-out and the surface-projected band gap emerging from atomic-layer corrugation. We then show that the extracted $d$-parameters can be straightforwardly applied to describe the optical response of various nanoscale metal morphologies of interest, including metallic ultra-thin films, graphene-metal heterostructures hosting extremely confined acoustic graphene plasmons, and crystallographic faceted metallic nanoparticles supporting localized surface plasmons. The tabulated $d$-parameters reported here can circumvent computationally expensive first-principles atomistic simulations to describe microscopic nonlocal effects in the optical response of mesoscopic crystalline metal surfaces, which are becoming widely available with increasing control over morphology down to atomic length scales for state-of-the-art experiments in nano-optics.

description: We consider asymptotically stable scalar-tensor dark energy (DE) models for which the equation of state parameter $w_{DE}$ tends to zero in the past. The viable models are of the phantom type today, however this phantomness is milder than in General Relativity if we take into account the varying gravitational constant when dealing with the SNIa data. We study further the growth of matter perturbations and we find a scaling behaviour on large redshifts which could provide an important constraint. In particular the growth of matter perturbations on large redshifts in our scalar-tensor models is close to the standard behaviour $δ_m \propto a$, while it is substantially different for the best-fit model in General Relativity for the same parametrization of the background expansion. As for the growth of matter perturbations on small redshifts, we show that in these models the parameter $γ'_0\equiv γ'(z=0)$ can take absolute values much larger than in models inside General Relativity. Assuming a constant $γ$ when $γ'_0$ is large would lead to a poor fit of the growth function $f$. This provides another characteristic discriminative signature for these models.

description: We tackle the problem of finding accurate and robust keypoint correspondences between images. We propose a learning-based approach to guide local feature matches via a learned approximate image matching. Our approach can boost the results of SIFT to a level similar to state-of-the-art deep descriptors, such as Superpoint, ContextDesc, or D2-Net and can improve performance for these descriptors. We introduce and study different levels of supervision to learn coarse correspondences. In particular, we show that weak supervision from epipolar geometry leads to performances higher than the stronger but more biased point level supervision and is a clear improvement over weak image level supervision. We demonstrate the benefits of our approach in a variety of conditions by evaluating our guided keypoint correspondences for localization of internet images on the YFCC100M dataset and indoor images on theSUN3D dataset, for robust localization on the Aachen day-night benchmark and for 3D reconstruction in challenging conditions using the LTLL historical image data.

Lateral wet oxidation of AIGaAs and its applications in high index contrast distributed feedback ridge waveguides
Creators: name: Chen, Peng
Publisher: name: University of British Columbia
Year: 2009

description: A high temperature wet oxidation technique has been developed to laterally oxidize high aluminum content Al[sub x]Ga[sub 1-x]As (x=98%) sandwiched between GaAs and low aluminum content Al[sub x]Ga[sub 1-x]As (x=70%). The oxides can be used to produce optical confinement and the current confinement in optoelectronic devices. To characterize the products of this high temperature oxidation, atomic force microscopy has been use to study the induced structure change. No significant vertical expansion has been detected demonstrating that this technique is particularly useful for distributed reflector devices. The composition of the oxidation product was also studied by x-ray photoelectron spectroscopy revealing that the high temperature oxidation produces arsenic poor A10[sub x]. We explained that the As is lost by thermal evaporation of AsH₃ during the high temperature oxidation process. By studying the binding energy of Al 2p core levels in the oxide, it has been found that the high aluminum content Al[sub x]Ga[sub 1-x]As (x=98%) oxidizes to an A10[sub x] while the low aluminum Al[sub x]Ga[sub 1-x]As (x=70%) produces Al₂O₃. To apply the lateral oxidation to distributed feedback waveguides, we used electron beam lithography and wet etching to fabricate test waveguides. By optimizing the process parameters, 100 nm linewidth gratings with spacing greater than 280nm have been achieved. A multipass writing technique was developed to attenuate the electron beam writing noise and achieve superior uniformity. The surface grating ridge waveguides have been fabricated on the laterally oxidized Al[sub x]Ga[sub 1-x] As layer successfully. Optical diffraction measurements have been conducted on second-order distributed-feedback waveguides containing a buried oxide with the grating pitch from 300 nm to 500 nm. The dispersion relationships of photon energy versus propagation constant have been determined for 440 nm and 460 nm grating waveguides. The experiments give the effective indices of the waveguides to be 1.7 for the both fundemental TE modes and fundemental TM modes, which show the guided modes were strongly modulated by the buried oxide.

description: Nach der Euphorie über den
      „Arabischen Frühling“ folgte schnell Ernüchterung. Betrachtet
      man die Situation in den Ländern der MENA-Region scheint
      allein Tunesien den Weg Richtung Demokratisierung zu gehen.
      Tunesien gilt als „Leuchtturm“– das Land, das erfolgreich aus
      den arabischen Umbrüchen hervorgehen konnte und nun zum
      letzten verbliebenen Hoffnungsträger geworden ist. Aus diesem
      Grund fokussiert sich nicht nur das mediale Interesse,
      sondern auch die Entwicklungshilfe westlicher Länder auf
      Tunesien. Zunehmende wirtschaftliche, kulturelle und
      Entwicklungszusammenarbeit in Form unzähliger Projekte sowie
      finanzieller Zuwendungen sollen helfen, das Land zu
      stabilisieren. Man fühlt sich Tunesien durch seine als
      säkular und frankophil perzipierte Kultur verbunden. Die
      Parlamentswahlen im Oktober 2014 sowie die
      Präsidentschaftswahlen im November 2014 gelten als große
      Erfolge für das Land. Doch wie erklärt sich in diesem Kontext
      der Zulauf zu jihadistischen Gruppen? Warum stellt das kleine
      Tunesien die größte Gruppe ausländischer Kämpfer in Syrien
      und im Irak? Und warum beteiligen sich immer mehr Tunesier an
      den Kämpfen im Nachbarland Libyen oder führen sogar Anschläge
      im eigenen Land durch?
The chemodynamics of prograde and retrograde Milky Way stars

description: Context: The accretion history of the Milky Way is still unknown, despite the recent discovery of stellar systems that stand out in terms of their energy-angular momentum space, such as Gaia-Enceladus-Sausage. In particular, it is still unclear how these groups are linked and to what extent they are well-mixed. Aims: We investigate the similarities and differences in the properties between the prograde and retrograde (counter-rotating) stars and set those results in context by using the properties of Gaia-Enceladus-Sausage, Thamnos/Sequoia, and other suggested accreted populations. Methods: We used the stellar metallicities of the major large spectroscopic surveys (APOGEE, Gaia-ESO, GALAH, LAMOST, RAVE, SEGUE) in combination with astrometric and photometric data from Gaia's second data-release. We investigated the presence of radial and vertical metallicity gradients as well as the possible correlations between the azimuthal velocity, $v_ϕ,$ and metallicity, [M/H], as qualitative indicators of the presence of mixed populations. Results: We find that a handful of super metal-rich stars exist on retrograde orbits at various distances from the Galactic center and the Galactic plane. We also find that the counter-rotating stars appear to be a well-mixed population, exhibiting radial and vertical metallicity gradients on the order of $\sim$ -0.04 dex/kpc and -0.06 dex/kpc, respectively, with little (if any) variation when different regions of the Galaxy are probed. The prograde stars show a $v_ϕ$-[M/H] relation that flattens -- and, perhaps, even reverses as a function of distance from the plane. Retrograde samples selected to roughly probe Thamnos and Gaia-Enceladus-Sausage appear to be different populations yet they also appear to be quite linked, as they follow the same trend in terms of the eccentricity versus metallicity space.
