Attaching seaweed spores to used scallop shells could restore UK’s coastal kelp forests
Kelp seaweed spores are being grown on small rocks and waste scallop shells as part of a trial exploring how to regenerate the UK’s coastal kelp forests.

The p-cycle of Holonomic D-modules and Quantization of Exact Algebraic Lagrangians
Let $X=\mathbb{A}^{n}$ be complex affine space, and let $T^{*}X$ be its cotangent bundle. For any exact Lagrangian $L\subset T^{*}X$, we define a new invariant, A, living in $ \text{Div}_{\mathbb{Q}/\mathbb{Z}}(L)$. We call this invariant the monodromy divisor of $L$. We conjecture that the existence of a finite order character of $π_{1}(L$) whose monodromy is exactly A defines an obstruction to attaching a holonomic $\mathcal{D}_{X}$-module M associated to L - here, the association goes via p…

Tiny Models are the Computational Saver for Large Models
This paper introduces TinySaver, an early-exit-like dynamic model compression approach which employs tiny models to substitute large models adaptively. Distinct from traditional compression techniques, dynamic methods like TinySaver can leverage the difficulty differences to allow certain inputs to complete their inference processes early, thereby conserving computational resources. Most existing early exit designs are implemented by attaching additional network branches to the model's backbone…

Sandpile groups for cones over trees

Sandpile groups for cones over trees
Sandpile groups are a subtle graph isomorphism invariant, in the form of a finite abelian group, whose cardinality is the number of spanning trees in the graph. We study their group structure for graphs obtained by attaching a cone vertex to a tree. For example, it is shown that the number of generators of the sandpile group is at most one less than the number of leaves in the tree. For trees on a fixed number of vertices, the paths and stars are shown to provide extreme behavior, not only for …

A Shintani lift for rigid cocycles
We construct a Shintani lift for rigid analytic cocycles of higher weight, attaching modular forms of half-integral weight to such cocycles. The expression for the Fourier coefficients of the modular form $\mathcal{RS}(J)$ attached to a cocycle $J$ is given in terms of the residues of $J$, and shares a striking similarity with the expression for the coefficients of the classical Shintani lift $\mathcal{S}(f)$ of an integral weight modular form $f$. This work aligns with the ideas of the nascent…

Scientists Propose New Way To Prevent Spread of Flu

For example, viral particles can bind to these molecules, known as sialic acids,

Top cell attachment for a Poincare Duality complex

Top cell attachment for a Poincare Duality complex
Let M be a simply-connected closed Poincare Duality complex of dimension n. Then M is obtained by attaching a cell of highest dimension to its (n-1)-skeleton M'. Conditions are given for when the skeletal inclusion i:M' --> M has the property that the based loops on i has a right homotopy inverse. This is an integral version of the rational statement that such a right homotopy inverse always exists provided the rational cohomology of M is not generated by a single element. New methods are devel…

Detecting the Néel vector of altermagnet by attaching a topological insulator and crystalline valley-edge insulator
In order to detect the Néel vector of an altermagnet, we investigate topological phases in a bilayer system composed of an altermagnet and a two-dimensional topological insulator described by the Bernevig-Hughes-Zhang model. A topological phase transition occurs from a first-order topological insulator to a trivial insulator at a certain critical altermagnetization if the Néel vector of altermagnet is along the $x$ axis or the $y$ axis. It is intriguing that valley-protected edge states emerg…

Properties of the `friend of a friend' model for network generation
The way in which a social network is generated, in terms of how individuals attach to each other, determines the properties of the resulting network. Here we study an intuitively appealing `friend of a friend' model, where a network is formed by each newly added individual attaching first to a randomly chosen target and then to $n_q\geq 1$ randomly chosen friends of the target, each with probability $0

Optimal Reeb graphs on two- and three-connected planar polygon
To investigate the topological structure of planar polygon decomposition on trapezoids, which is formed by height functions. We use the oriented Reeb graph of the function with a marked vertex. We describe all possible optimal Reeb graphs in the case of polygon in general position with one local minimum and one local maximum. By optimal Reeb graph we mean Reeb graph, which cann't be obtaned from other Reeb graph by subdivision of an edge or a leaf attaching. In this case polygon is a triangle w…

Retrosynthesis Prediction via Search in (Hyper) Graph
Predicting reactants from a specified core product stands as a fundamental challenge within organic synthesis, termed retrosynthesis prediction. Recently, semi-template-based methods and graph-edits-based methods have achieved good performance in terms of both interpretability and accuracy. However, due to their mechanisms these methods cannot predict complex reactions, e.g., reactions with multiple reaction center or attaching the same leaving group to more than one atom. In this study we prop…

Morse theory for group presentations
We introduce a novel combinatorial method to study $Q^{**}$-transformations of group presentations or, equivalently, 3-deformations of CW-complexes of dimension 2. Our procedure is based on a refinement of discrete Morse theory that gives a Whitehead simple homotopy equivalence from a regular CW-complex to the simplified Morse CW-complex, with an explicit description of the attaching maps and bounds on the dimension of the complexes involved in the deformation. We apply this technique to show t…
