Adhesive category theory for graph rewriting in Rocq
We design a Rocq library about adhesive categories, using Hierarchy Builder (HB). It is built around two hierarchies. The first is for categories, with usual categories at the bottom and adhesive categories at the top, with weaker variants of adhesive categories in between. The second is for morphisms (notably isomorphisms, monomorphisms and regular monomorphisms). Each level of these hierarchies is equipped with several interfaces to define instances. We cover basic categorical concepts such a…

Prefetching in Deep Memory Hierarchies with NVRAM as Main Memory
Emerging applications, such as big data analytics and machine learning, require increasingly large amounts of main memory, often exceeding the capacity of current commodity processors built on DRAM technology. To address this, recent research has focused on off-chip memory controllers that facilitate access to diverse memory media, each with unique density and latency characteristics. While these solutions improve memory system performance, they also exacerbate the already significant memory la…

I refuse to replace capitalist hierarchies with red-tinted authoritarianism, because in the end, I want liberation, not another power structure draped in red with the hammer and sickle.

Quantumness and its hierarchies in PT-symmetric down-conversion models
We investigate the hierarchy of quantum correlations in a quadratic bosonic parity-time-symmetric system (PTSS) featuring distinct dissipation and amplification channels. The hierarchy includes global nonclassicality, entanglement, asymmetric quantum steering, and Bell nonlocality. We elucidate the interplay between the system physical nonlinearity -- which serves as a source of quantumness -- and the specific dynamics of bosonic PTSSs, which are qualitatively influenced by their damping and am…

A Semantics-Aware Hierarchical Self-Supervised Approach to Classification of Remote Sensing Images
Deep learning has become increasingly important in remote sensing image classification due to its ability to extract semantic information from complex data. Classification tasks often include predefined label hierarchies that represent the semantic relationships among classes. However, these hierarchies are frequently overlooked, and most approaches focus only on fine-grained classification schemes. In this paper, we present a novel Semantics-Aware Hierarchical Consensus (SAHC) method for learn…

The loser's brain: How neuroscience controls social behavior
Social hierarchies are everywhere—think of high school dramas, where the athletes are portrayed as the most popular, or large companies, where the CEO makes the important decisions. Such hierarchies aren't just limited to humans, but span the animal kingdom, with dominant individuals getting faster food access, higher mating priority, and bigger or better territories. While it's long been thought that winning or losing can influence the position of an individual within a social hierarchy, the…

Hierarchies 😩... One of the biggest recurring time-consuming issues I sometimes encounter is making decisions about _where_ to put some (new or exisiting) code/feature, i.e. in which package, new or existing, considering: functional fit (topic), structural fit (pre-existing data format conventions with the rest of a package), and if possible, not introducing new dependencies as a result of new feature... Sometimes these three aspects are mutually blocking each other and it's so time cons…

Complexity hierarchies in Euclidean stars

Complexity hierarchies in Euclidean stars
We establish a hierarchy of Euclidean stars according to their degree of complexity, as measured by the complexity factor and the complexity of the pattern of evolution. We consider both, nondissipative and dissipative systems. Solutions are ranged from the simplest one, in order of increasing complexity. Some specific models are found and analyzed in detail.

A Triad of Networks and a Triad of Fusions for the Other Climate Crisis
Shaw and Stevens call for a new paradigm in climate science criticizes Large Scale Determinism in favor of (i) embracing discrepancies, (ii) embracing hierarchies, and (iii) create disruption while keeping interpretability. The last 20 years have seen a plethora of contributions relating complex networks with climate data and climate models. We provide a view of climate networks through a triad of frameworks and associated paradigms: (a) networks of data, where both (geographical) nodes and the…

Flavour, Accidentally
We propose a new class of flavour models in which the spurion which breaks Standard Model flavour symmetries transforms in a non-minimal representation. Hierarchies in fermion masses, which arise from multiple insertions of this spurion, may be generated in a technically natural, accidental manner, from a handful of untuned $\mathcal{O}(1)$ elements in the UV. This relies explicitly on the non-Abelian nature of the symmetry, distinguishing it from standard Froggatt-Nielsen-like scenarios. The p…

On a matrix constrained CKP hierarchy
The algebraic structures of integrable hierarchies play an important role in the study of soliton equations. In this paper, we use splitting theory to give a matrix representation of a constrained CKP hierarchy, which can be considered as a generalization of the $\hat{A}_{2n}^{(2)}$-KdV hierarchy and the constrained KP hierarchy. An equivalent construction in terms of the pseudo-differential operator is discussed. Darboux transformations, scaling transformation and tau functions $\ln τ_f$ for …

If you love Marshal Kim Jong Un, the so-called "beloved" dictator of North Korea, where people are forced to bow down not out of respect but because the regime literally outlaws standing upright for more than three seconds to prevent neck strain then I see you as enforcers of authoritarian misery not my comrade.
Real solidarity means rejecting all hierarchies and authoritarian rule, dismantling the capitalist states that oppress workers under the pretense of loyalty, and buil…

Algebra of operators for Q-Schur polynomials
We consider algebras acting on Schur and Q-Schur polynomials, corresponding to Kadomtsev-Petviashvili (KP) and BKP hierarchies. We present them in the spirit of affine Yangians, paying special attention to commutative subalgebras, box additivity property of eigenvalues and single hook expansion of operators.

Generalized discrete integrable operator and integrable hierarchy

Abstract: We introduce and systematically develop two classes of discrete integrable operators: those with $2\times 2$ matrix kernels and those possessing general differential kernels, thereby generalizing the discrete analogue previously studied. A central finding is their inherent connection to higher-order pole solutions of integrable hierarchies, contrasting sharply with standard operators linked to simple poles. This work not only provides explicit resolvent formulas for matrix kernels and differential operator analogues but also offers discrete integrable structures that encode higher-order behaviour.

Asymmetric rational reductions of 2D-Toda hierarchy and a generalized Frobenius manifold
We study the local bihamiltonian structures of the asymmetric rational reductions of the 2D-Toda hierarchy (RR2T) of types $(2,1)$ and $(1,2)$ at the full-dispersive level, and construct a three-dimensional generalized Frobenius manifold with non-flat unity associated with the $(2,1)$-type. Furthermore, we explicitly relate the $(2,1)$-type RR2T to the bi-graded Toda and constrained KP hierarchies via linear reciprocal and Miura-type transformations.
