description: We study a graph partitioning problem motivated by the simulation of the physical movement of multi-body systems on an atomistic level, where the forces are calculated from a quantum mechanical description of the electrons. Several advanced algorithms have been published in the literature for such simulations that are based on evaluations of matrix polynomials. We aim at efficiently parallelizing these computations by using a special type of graph partitioning. For this, we represent the zero-nonzero structure of a thresholded matrix as a graph and partition that graph into several components. The matrix polynomial is then evaluated for each separate submatrix corresponding to the subgraphs and the evaluated submatrix polynomials are used to assemble the final result for the full matrix polynomial. The paper provides a rigorous definition as well as a mathematical justification of this partitioning problem. We use several algorithms to compute graph partitions and experimentally evaluate their performance with respect to the quality of the partition obtained with each method and the time needed to produce it.

description:  Abstract: An innovative adaptive line enhancer (ALE) structure is presented in this work. The adaptive filter's autoregressive-moving average (ARMA) structure is based on traditional Laguerre orthogonal func­tions. The orthogonal set's poles' frequencies and radii allow for tuning. Higher-order statistics are used to tune these terms in this contribution. Fourth-order cumulants' qualities are used to help with harmonic retrieval of the sinusoids embedded in the input signal. Since the feed-forward filter parameters are linearly connected to the filter output, further adaption of them is simple. Stability, brevity, and robustness in the presence of noise are expected benefits. Results from simulations are presented to demonstrate typical performance.
Culinary Professions in Early Modern Italian Comedy

description: This dissertation explores representations of the cook and the deliveryman – il cuoco e lo zanaiuolo – in Renaissance Italian comedy (1509-1560). The figure of the cook is well established in ancient comedy and in Athenaeus’s Deipnosophistae (The Learned Banqueters), and centuries later several playwrights, including Ludovico Ariosto, Agnolo Firenzuola, Alessandro Piccolomini, Giovan Battista Gelli, and Giovanni Maria Cecchi, feature cooks and novel food purveyors in their comedies. In a rapidly changing Early Modern society, culinary professionals provide crucial insight into the sustenance of households in urban centers, mediating how communities interact with their foods. As members of the working class, cooks and deliverymen offer a unique perspective on social dynamics of the period, different from that offered by political and religious courts. Comedies that include these professionals rely, in part, on previous canons to characterize the figures, yet they do so in conversation with contemporary settings and everyday realities of Early Modern Italy. As cooks reappear on the stage throughout the sixteenth century, typified roles establish them as a Renaissance version of the classical stock character. The development of the novel deliveryman as a member of the cast, instead, suggests an increasingly diverse number of professions in Italian city centers and a consequential push towards innovative representations of a more inclusive world in Early Modern theater.

description: Visual place recognition (VPR) is a robot's ability to determine whether a place was visited before using visual data. While conventional hand-crafted methods for VPR fail under extreme environmental appearance changes, those based on convolutional neural networks (CNNs) achieve state-of-the-art performance but result in heavy runtime processes and model sizes that demand a large amount of memory. Hence, CNN-based approaches are unsuitable for resource-constrained platforms, such as small robots and drones. In this paper, we take a multi-step approach of decreasing the precision of model parameters, combining it with network depth reduction and fewer neurons in the classifier stage to propose a new class of highly compact models that drastically reduces the memory requirements and computational effort while maintaining state-of-the-art VPR performance. To the best of our knowledge, this is the first attempt to propose binary neural networks for solving the visual place recognition problem effectively under changing conditions and with significantly reduced resource requirements. Our best-performing binary neural network, dubbed FloppyNet, achieves comparable VPR performance when considered against its full-precision and deeper counterparts while consuming 99% less memory and increasing the inference speed seven times.
An Evolutionary Strategy based on Partial Imitation for Solving Optimization Problems

description: In this work we introduce an evolutionary strategy to solve combinatorial optimization tasks, i.e. problems characterized by a discrete search space. In particular, we focus on the Traveling Salesman Problem (TSP), i.e. a famous problem whose search space grows exponentially, increasing the number of cities, up to becoming NP-hard. The solutions of the TSP can be codified by arrays of cities, and can be evaluated by fitness, computed according to a cost function (e.g. the length of a path). Our method is based on the evolution of an agent population by means of an imitative mechanism, we define `partial imitation'. In particular, agents receive a random solution and then, interacting among themselves, may imitate the solutions of agents with a higher fitness. Since the imitation mechanism is only partial, agents copy only one entry (randomly chosen) of another array (i.e. solution). In doing so, the population converges towards a shared solution, behaving like a spin system undergoing a cooling process, i.e. driven towards an ordered phase. We highlight that the adopted `partial imitation' mechanism allows the population to generate solutions over time, before reaching the final equilibrium. Results of numerical simulations show that our method is able to find, in a finite time, both optimal and suboptimal solutions, depending on the size of the considered search space.

The chromatic number of dense random graphs

Publisher: name: arXiv
Year: 2016
Subjects: subject: Combinatorics (math.CO)

subject: 05C15, 05C80

description: The chromatic number $χ(G)$ of a graph $G$ is defined as the minimum number of colours required for a vertex colouring where no two adjacent vertices are coloured the same. The chromatic number of the dense random graph $G \sim G(n,p)$ where $p \in (0,1)$ is constant has been intensively studied since the 1970s, and a landmark result by Bollobás in 1987 first established the asymptotic value of $χ(G)$. Despite several improvements of this result, the exact value of $χ(G)$ remains open. In this paper, new upper and lower bounds for $χ(G)$ are established. These bounds are the first ones that match each other up to a term of size $o(1)$ in the denominator: they narrow down the colouring rate $n/χ(G)$ of $G \sim G(n,p)$ to an explicit interval of length $o(1)$, answering a question of Kang and McDiarmid.

description: We investigate the parity of the coefficients of certain eta-quotients, extensively examining the case of $m$-regular partitions. Our theorems concern the density of their odd values, in particular establishing lacunarity modulo 2 for specified coefficients; self-similarities modulo 2; and infinite families of congruences in arithmetic progressions. For all $m \leq 28$, we either establish new results of these types where none were known, extend previous ones, or conjecture that such results are impossible. All of our work is consistent with a new, overarching conjecture that we present for arbitrary eta-quotients, greatly extending Parkin-Shanks' classical conjecture for the partition function. We pose several other open questions throughout the paper, and conclude by suggesting a list of specific research directions for future investigations in this area.

Expectation values of minimum-length Ricci scalar

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this paper, we consider a specific model, implementing the existence of a fundamental limit distance $L_0$ between (space or time separated) points in spacetime, which in the recent past has exhibited the intriguing feature of having a minimum-length Ricci scalar $R_{(q)}$ that does not approach the ordinary Ricci scalar $R$ in the limit of vanishing $L_0$. $R_{(q)}$ at a point has been found to depend on the direction along which the existence of minimum distance is implemented. Here, we point out that the convergence $R_{(q)}\to R$ in the $L_0\to 0$ limit is anyway recovered in a relaxed or generalized sense, which is when we average over directions, this suggesting we might be taking the expectation value of $R_{(q)}$ promoted to be a quantum variable. It remains as intriguing as before the fact that we cannot identify (meaning this is much more than simply equating in the generalised sense above) $R_{(q)}$ with $R$ in the $L_0\to 0$ limit, namely when we get ordinary spacetime. Thing is like if, even when $L_0$ (read here the Planck length) is far too small to have any direct detection of it feasible, the intrinsic quantum nature of spacetime might anyway be experimentally at reach, witnessed by the mentioned special feature of Ricci, not fading away with $L_0$ (i.e. persisting when taking the $\hbar \to 0$ limit).

Annotating Adverse Outcome Pathways to Organize Toxicological Information for Risk Assessment
Creators: name: Ives, Cataia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The Adverse Outcome Pathway (AOP) framework connects molecular perturbations with organism and population level endpoints used for regulatory decision-making by providing a conceptual construct of the mechanistic basis for toxicity. Development of an AOP typically begins with the adverse outcome, and intermediate effects connect the outcome with a molecular initiating event amenable to high-throughput toxicity testing (HTT). Publicly available controlled vocabularies were used to provide terminology supporting AOP’s at all levels of biological organization. The resulting data model contains terms from 22 ontologies and controlled vocabularies annotating currently existing AOP’s. The model provides the ability to attach evidence in support of the AOP, supports data aggregation, and promotes the development of AOP networks. Long term, this structured description of the AOP will enable logical reasoning for hazard identification and for dose-response assessment. Case studies showcase how the model informs AOP development in the context of chemical risk assessment.

description: Exciton-polaritons constitute a unique realization of a quantum fluid interacting with its environment. Using Selenide based microcavities, we exploit this feature to warm up a polariton condensate in a controlled way and monitor its spatial coherence. We determine directly the amount of heat picked up by the condensate by measuring the phonon-polariton scattering rate and comparing it with the loss rate. We find that upon increasing the heating rate, the spatial coherence length decreases markedly, while localized phase structures vanish, in good agreement with a stochastic mean field theory. From the thermodynamical point-of-view, this regime is unique as it involves a nonequilibrium quantum fluid with no well-defined temperature, but which is nevertheless able to pick up heat with dramatic effects on the order parameter.

description: Effective, robust, and automatic tools for brain tumor segmentation are needed for the extraction of information useful in treatment planning from magnetic resonance (MR) images. Context-aware artificial intelligence is an emerging concept for the development of deep learning applications for computer-aided medical image analysis. In this work, it is investigated whether the addition of contextual information from the brain anatomy in the form of white matter, gray matter, and cerebrospinal fluid masks and probability maps improves U-Net-based brain tumor segmentation. The BraTS2020 dataset was used to train and test two standard 3D U-Net models that, in addition to the conventional MR image modalities, used the anatomical contextual information as extra channels in the form of binary masks (CIM) or probability maps (CIP). A baseline model (BLM) that only used the conventional MR image modalities was also trained. The impact of adding contextual information was investigated in terms of overall segmentation accuracy, model training time, domain generalization, and compensation for fewer MR modalities available for each subject. Results show that there is no statistically significant difference when comparing Dice scores between the baseline model and the contextual information models, even when comparing performances for high- and low-grade tumors independently. Only in the case of compensation for fewer MR modalities available for each subject did the addition of anatomical contextual information significantly improve the segmentation of the whole tumor. Overall, there is no overall significant improvement in segmentation performance when using anatomical contextual information in the form of either binary masks or probability maps as extra channels.

A priori bounds for rough differential equations with a non-linear damping term

description: We consider a rough differential equation with a non-linear damping drift term: \begin{align*} dY(t) = - |Y|^{m-1} Y(t) dt + σ(Y(t)) dX(t), \end{align*} where $X$ is a branched rough path of arbitrary regularity $α>0$, $m>1$ and where $σ$ is smooth and satisfies an $m$ and $α$-dependent growth property. We show a strong a priori bound for $Y$, which includes the "coming down from infinity" property, i.e. the bound on $Y(t)$ for a fixed $t>0$ holds uniformly over all choices of initial datum $Y(0)$. The method of proof builds on recent work by Chandra, Moinat and Weber on a priori bounds for the $ϕ^4$ SPDE in arbitrary subcritical dimension. A key new ingredient is an extension of the algebraic framework which permits to derive an estimate on higher order conditions of a coherent controlled rough path in terms of the regularity condition at lowest level.

PREDATOR-PREY RELATIONSHIPS BETWEEN CRASSOSTREA VIRGINICA AND SEVERAL SPECIES OF CRAB AFFECT OYSTER REEF FUNCTION
Creators: name: Dodd, Luke

Subjects: subject: Ecology
subject: FOS: Biological sciences

description: Direct and indirect effects resulting from predator-prey interactions can affect ecosystem function. Understanding these relationships has been a central focus of community ecology for more than 50 years. However, human impacts on ecosystems during this period may have altered these relationships. Here I assess important impacts of ocean acidification, ocean warming, and land-use change on the predator-prey relationships between the oyster, Crassostrea virginica, and several species of crab. Calcifying marine taxa have been shown to respond differently to ocean acidification. Bivalves typically show more severe reductions in net calcification than the decapods that prey on them. This study found C. virginica and the crab, Panopeus herbstii, had generally reduced net calcification with decreasing calcite saturation states. However, both species maintained positive net calcification in undersaturated calcite conditions. In experiments, acidification significantly reduced the consumption rate of C. virginica by P. herbstii. Differences in net calcification did not explain consumption rates, rather behavioral change, manifest as reduced prey handling and persistence of the predator, were the likely cause. Ocean warming is driving pole-ward shifts in the ranges of numerous species, leading to the formation of novel communities. The stone crab, Menippe mercenaria, is one such species, but little is known about its ecology and thus its like impact on ecosystems in its new range. My data suggest that crabs between 70 and 90 mm are likely to have the largest effect on intertidal oyster reefs due to higher consumption rates and an ability to consume all sizes of oyster. Smaller crabs are limited by the size of oyster they can consume and larger crabs demonstrated less interest in oyster as a prey item. Land-use change and accompanying habitat loss has driven increased interest in estuarine ecosystem services and functions. C. virginica relies on filtration to provide its outsized contribution to estuarine ecosystem function and services. Other species of bivalves reduce their filtration rates to reduce their predation exposure. However, C. virginica showed no such behavior in the presence of two common crab predators. This research highlights the dynamism of predator-prey relationships and their important role in current and future ecosystem function.

description: We prove that the Gibbs measures $ρ$ for a class of Hamiltonian equations written $\partial_t u = J (-\triangle u + V'(|u|^2)u)$ on the real line are invariant under the flow of this equation in the sense that there exist random variables $X(t)$ whose laws are $ρ$ (thus independent from $t$) and such that $t\mapsto X(t)$ is a solution to the above equation. Besides, for all $t$, $X(t)$ is almost surely not in $L^2$ which provides as a direct consequence the existence of weak solutions for initial data not in $L^2$. The proof uses Prokhorov's theorem, Skorohod's theorem, as in the strategy in \cite{burqtzv} and Feynman-Kac's integrals.

description: Spin-dependent fifth-forces are associated with particles beyond the standard model. In particular, light pseudo-scalar bosons mediate long-range forces, allowing mass to interact with spins. The search of these interactions can be performed by periodically varying the distance between a source mass and a spin ensemble, in order to modulate the force intensity and detect it with precision magnetometry techniques. In our setup the force arises from room temperature lead masses and is detected in a paramagnetic crystal at 4.2\,K, whose magnetisation is monitored by a SQUID-based magnetometer with the sensitivity of $53\,\mathrm{aT/\sqrt{Hz}}$. Our measurement places the most stringent constraints on a spin-mass interaction in the ranges 1\,cm to 10\,m and 10\,km to 300\,km, improving existing limits up to more than two orders of magnitude. We show that this experimental technique may be further leveraged to explore a vast region of the fifth force's parameter space, with an interaction range longer than a few centimetres.

description: We investigate Friedl-Lück's universal $L^2$-torsion for descending HNN extensions of finitely generated free groups, and so in particular for $F_n$-by-$\mathbb{Z}$ groups. This invariant induces a semi-norm on the first cohomology of the group which is an analogue of the Thurston norm for $3$-manifold groups. We prove that this Thurston semi-norm is an upper bound for the Alexander semi-norm defined by McMullen, as well as for the higher Alexander semi-norms defined by Harvey. The same inequalities are known to hold for $3$-manifold groups. We also prove that the Newton polytopes of the universal $L^2$-torsion of a descending HNN extension of $F_2$ locally determine the Bieri-Neumann-Strebel invariant of the group. We give an explicit means of computing the BNS invariant for such groups. As a corollary, we prove that the Bieri-Neumann-Strebel invariant of a descending HNN extension of $F_2$ has finitely many connected components. When the HNN extension is taken over $F_n$ along a polynomially growing automorphism with unipotent image in $GL(n, \mathbb{Z})$, we show that the Newton polytope of the universal $L^2$-torsion and the BNS invariant completely determine one another. We also show that in this case the Alexander norm, its higher incarnations, and the Thurston norm all coincide.

description: Regular physical activity has significant benefits for health, including improviment in muscular and cardiorespiratory fitness, bone and functional health, and reduce the risk of comorbities. On the other hand, insufficient physical activity level is one of the leading risk factors for global mortality. Digital health interventions are a very promising option to help adults to overcome geographic and physical barriers to increase physical activity levels. Thus, the aim of this study is to evaluate the effectiveness of digital health interventions to improve physical activity levels in adults.

Semiparametric two-component mixture models under linear constraints

Year: 2016
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: We propose a structure of a semiparametric two-component mixture model when one component is parametric and the other is defined through linear constraints on its distribution function. Estimation of a two-component mixture model with an unknown component is very difficult when no particular assumption is made on the structure of the unknown component. A symmetry assumption was used in the literature to simplify the estimation. Such method has the advantage of producing consistent and asymptotically normal estimators, and identifiability of the semiparametric mixture model becomes tractable. Still, existing methods which estimate a semiparametric mixture model have their limits when the parametric component has unknown parameters or the proportion of the parametric part is either very high or very low. We propose in this paper a method to incorporate a prior linear information about the distribution of the unknown component in order to better estimate the model when existing estimation methods fail. The new method is based on $φ-$divergences and has an original form since the minimization is carried over both arguments of the divergence. The resulting estimators are proved to be consistent and asymptotically normal under standard assumptions. We show that using the Pearson's $χ^2$ divergence our algorithm has a linear complexity when the constraints are moment-type. Simulations on univariate and multivariate mixtures demonstrate the viability and the interest of our novel approach.

description: We describe the construction of traversable wormholes with multiple mouths in four spacetime dimensions and discuss associated quantum entanglement. Our wormholes may be traversed between any pair of mouths. In particular, in the three-mouth case they have fundamental group $F_2$ (the free group on two generators). By contrast, connecting three regions $A,B,C$ in pairs ($AB$, $BC$, and $AC$) using three separate wormholes would give fundamental group $F_3$. Our solutions are asymptotically flat up to the presence of possible magnetic fluxes or cosmic strings that extend to infinity. The construction begins with a two-mouth traversable wormhole supported by backreaction from quantum fields. Inserting a sufficiently small black hole into its throat preserves traversability between the original two mouths. This black hole is taken to be the mouth of another wormhole connecting the original throat to a new distant region of spacetime. Making the new wormhole traversable in a manner similar to the original two-mouth wormhole provides the desired causal connections. From a dual field theory point of view, when AdS asymptotics are added to our construction, multiparty entanglement may play an important role in the traversability of the resulting wormhole.

Recovery of Infraspinatus Cross Sectional Area, Echo Intensity, and Glenohumeral Range of Motion Following Bouts of Overhand Pitching
Creators: name: Pexa, Brett
Publisher: name: University of North Carolina at Chapel Hill Graduate School

Subjects: Medical sciences

description: Previous work demonstrates that eccentric load associated with baseball pitching results in swelling of the infraspinatus, with accompanying changes in glenohumeral flexibility. Infraspinatus swelling and flexibility measurements provide markers for both trauma that results from pitching and a means to monitor recovery following pitching. The purpose of this study was to longitudinally track changes in measures of infraspinatus swelling (cross-sectional area and echo intensity) and humeral rotation flexibility daily, up to 7 days following a bout of pitching. Ten Division 1 baseball pitchers volunteered as participants. One general linear model was run to analyze change in scores per dependent variable per limb (twelve in total). Infraspinatus cross-sectional area increased one day following pitching and internal rotation decreased for three days after pitching. Baseball pitchers cause damage that can last up to 3 days. Recovery must occur to pitch on subsequent days so arms may return to baseline before reapplying stress.
Several realizations of Fock modules for quantum toroidal algebras of sl(n)
Creators: name: Tsymbaliuk, Alexander
Publisher: name: arXiv
Year: 2016
Subjects: subject: Representation Theory (math.RT)
subject: FOS: Mathematics

description: In this paper, we relate the well-known Fock representations of the quantum toroidal algebra of sl(n) to the vertex, shuffle, and L-operator representations of the same algebra. These identifications generalize those for the quantum toroidal algebra of gl(1), which were recently established by Feigin-Jimbo-Miwa-Mukhin.

Experimental measurement of the collectibility of two-qubit states

description: We present a proof-of-principle experiment demonstrating measurement of the collectibility, a nonlinear entanglement witness proposed by Rudnicki et al. [Phys. Rev. Lett. 107, 150502 (2011)]. This entanglement witness works for both mixed and pure two-qubit states. In the later case it can be used to measure entanglement in terms of the negativity. We measured the collectibility for three distinct classes of photonic polarization-encoded two-qubit states, i.e., maximally entangled, separable and maximally mixed states. We demonstrate that the measurement procedure is feasible and robust against typical experimental shortcomings such as imperfect two-photon indistinguishability.

The Creation of Shared Memory: The Theater Reliefs from Hierapolis

History

description: The theater reliefs from the site of Hierapolis were first published in 1898 by Carl Humann and since then have been discussed by multiple scholars. However, rarely are all of the reliefs from the theater discussed in the same work. More often than not, scholars either choose to focus on the podium reliefs or on the reliefs from the porta regia and leave only a few cursory lines to deal with the rest of the sculpted reliefs from the theater, if they are mentioned at all. This paper seeks to look at the entire sculpted relief program from the theater at Hierapolis and not only analyze how the iconographic program of the theater fits together, but also the message that is being broadcast to the citizens of Hierapolis.
Perceptions of bias in a changing media environment: the hostile media effect for objective and ideological media
Creators: name: Dunn, Scott Wilson
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: This dissertation broadens scholarly understanding of perceptions of media bias by examining the hostile media effect in the context of explicitly ideological media. The hostile media effect states that people who have strong attitudes on a given issue will perceive media coverage of that issue as hostile to their attitudes, even while people with the opposing attitude may see the same coverage as biased in the other direction. However, most previous research on the hostile media effect has been based on stimuli that ostensibly come from traditional mainstream media sources that profess to uphold a standard of objectivity. This study incorporated stimulus articles said to come from media sources with explicit conservative or liberal biases. The study found that, for an article about abortion, participants tended to base their perceptions of bias on the media outlet's explicit ideology. However, for an article about the economy, participants who supported government intervention to solve economic problems perceived the article as biased regardless of the media outlet's stated ideology, lending partial support to the traditional hostile media effect. In addition to testing the differences in perceived bias for ideological and neutral media, this study also tested a number of antecedents and consequences that have been identified in previous research on the hostile media effect. For both articles, perceptions of general media bias predicted perceptions that the articles and their media outlet were biased. Group identification, attitude extremity, connection between attitudes and moral conviction, media cynicism, and political tolerance did not predict perceptions of bias. For the abortion article, perceived bias predicted perceptions of how credible and informative the media outlet was and perceptions of public opinion about abortion, but not how interesting the media outlet was or levels of general media indignation. For the economy article, perceived bias predicted all perceptions of how credible, informative, and interesting the media outlet was, but not media indignation or perceived public opinion. Implications of these findings and suggestions for future research are discussed.
"EXCUSE ME, MR. . . ., I'M SPEAKING." FINDING THE BLACK TEACHER VOICE AND POWER IN EDUCATOR TEAMS

description: The focus of this study was to support teachers of color improve their perceptions of the power, voice, and respect they possess in educator teams. The literature suggested that Black teachers were subjected to discriminatory racial encounters that results in racial battle fatigue. I examined this research from multiple theoretical lenses. I paired critical race theory with phenomenological variant of ecological systems theory (PVEST) and racial encounter coping appraisal and socialization theory (RECAST) to help deconstruct a part of the problem with regards to race. I also considered collective teacher efficacy theory and community of practice theory to explain team dynamics. I delineated professional learning communities (PLCs) and other educator teams in schools. Additionally, I examined the organizational hierarchy of Eurocentric norms that eroded team cultures in schools. This study required a phenomenological approach through a dissertation in practice with three change theories: (a) developing a uniformed response to micro-aggression, (b) racializing PLCs, and (c) vetting teacher contracts for race-neutral language with regards to teams. There were five participants, who identified as Black. I used observations, interview questions and surveys as tools to measure the progress of the study. A primary focus also included improving the participants’ racial literacy as a way to respond to micro-aggression. As a result of the study, I observed the many ways in which Black teachers were silenced at our site. I communicated the distinctions between performative and coconspirator allyship. I developed two emerging theoretical constructs: racial silencing in teams theory (RSTT) and parallel racial strife theory (PRST) to contribute to the existing literature.

description: We provide a proof that every Schubert variety of a semi-infinite flag variety is projectively normal. This gives us an interpretation of a Demazure module of a global Weyl module of a current Lie algebra as the (dual) space of the space of global sections of a semi-infinite Schubert variety. Moreover, we give geometric realizations of Feigin-Makedonskyi's generalized Weyl modules, and the $t = \infty$ specialization of non-symmetric Macdonald polynomials.
