This is Part I of a two-part series regarding Ramsey properties of Fraisse structures satisfying a property called SDAP+, which strengthens the Disjoint Amalgamation Property. We prove that every Fraisse structure in a finite relational language with...
Fifty five planetary nebulae containing micro-structures of low-ionization (LIS) are analyzed in this review in terms of LIS morphology, kinematics, and physical and excitation properties. We attempt to address the issue of their origin through the...
Oct 2, 2025 · Learn the different types of structures in civil engineering, from buildings and bridges to dams and towers, with examples and design insights.
The project database of Structurae currently contains structures on every continent of the world – including Antarctica – and which can also be found via geographic browsing.
Nov 14, 2025 · The types of structures used in construction vary widely depending on the building’s function, expected load, site conditions, materials, and architectural requirements.
Structures aims to publish internationally-leading research across the full breadth of structural engineering.
Let’s make a list of all the structures we should recognize- H3PO4, imine, enamine, tosylate, dopamine, vitamin A, etc!...
Bilayer graphene nanoribbon with zigzag edge is investigated with the tight binding model. Two stacking structures, alpha and beta, are considered. The band splitting is seen in the alpha structure, while the splitting in the wave number direction is...
Syntactic Structures is a seminal work in linguistics by American linguist Noam Chomsky, originally published in 1957. A short monograph of about a hundred
Asking for someone that wants to do structures with no experience, what kind of things no one really talks about or understands? How much stuff that can go wrong actually goes wrong ? ...
We introduce BV-algebra structures on the homology of the space of framed long knots in $\mathbb{R}^n$ in two ways. The first one is given in a similar fashion to Chas-Sullivan's string topology. The second one is defined on the Hochschild homology a...
In this article, we study model structures on the category of finite graphs with $\times$-homotopy equivalences as the weak equivalences. We show that there does not exist an analogue of Strøm-Hurewicz model structure on this category of graphs. Mor...
Suffix trees and suffix arrays are two of the most widely used data structures for text indexing. Each uses linear space and can be constructed in linear time for polynomially sized alphabets. However, when it comes to answering queries with worst-ca...
Contains all data structure implemented using linked list such as ,queues ,stack ,priority queues , binary ,tees, heap etc (⭐ 0)
This paper applies Algorithmic Information Theory to simple examples of replication processes to illustrate how replicating structures can generate and maintain order in a non equilibrium system. Variation in replicating structures enhances the sys...
We present a detailed study of elliptic fibrations on Fourier-Mukai partners of K3 surfaces, which we call derived elliptic structures. We fully classify derived elliptic structures in terms of Hodge-theoretic data, similar to the Derived Torelli The...
Title: From favorable atomic configurations to supershell structures: a new interpretation of conductance histograms Authors: A. Hasmy (IVIC), E. Medina (IVIC), P.A. Serena (CSIC,IVIC) Comments: 7 pages, 3 figures, cond-mat.anwar.10825 Subj-class:...
The sequential semantics of many concurrent data structures, such as stacks and queues, inevitably lead to memory contention in parallel environments, thus limiting scalability. Semantic relaxation has the potential to address this issue, increasing...
Accurate prediction of protein-ligand binding structures, a task known as molecular docking is crucial for drug design but remains challenging. While deep learning has shown promise, existing methods often depend on holo-protein structures (docked, a...
In this paper we introduce the Ladder Algorithm; a novel recurrent algorithm to detect repetitive structures in natural images with high accuracy using little training data. We then demonstrate the algorithm on the task of extracting vertebrae from...
