Coded Caching based on Combinatorial Designs

, 2020
We consider the standard broadcast setup with a single server broadcasting information to a number of clients, each of which contains local storage (called \textit{cache}) of some size, which can store some parts of the available files at the server. The

Nontrivial t-Designs over Finite Fields Exist for All t

, 2013
A $t$-$(n,k,\lambda)$ design over $\F_q$ is a collection of $k$-dimensional subspaces of $\F_q^n$, called blocks, such that each $t$-dimensional subspace of $\F_q^n$ is contained in exactly $\lambda$ blocks.

Combinatorial assembly and design of enzymes

Science, 2022
The design of structurally diverse enzymes is constrained by long-range interactions that are necessary for accurate folding. We introduce an atomistic and machine learning strategy for the combinatorial assembly and design of enzymes (CADENZ) to design fragments that combine with one another to generate diverse, low-energy structures with stable ...

A Census Of Highly Symmetric Combinatorial Designs

, 2007
As a consequence of the classification of the finite simple groups, it has been possible in recent years to characterize Steiner t-designs, that is t-(v,k,1) designs, mainly for t = 2, admitting groups of automorphisms with sufficiently strong symmetry ...

Small examples of mosaics of combinatorial designs

Examples and Counterexamples
We give the first example of a mosaic of three combinatorial designs with distinct parameters 2-(13,3,1), 2-(13,4,2), and 2-(13,6,5). Furthermore, we give examples of mosaics of 2-(9,3,2) designs that are not resolvable, thereby answering a question ...

Modeling and Optimization for Connection Design of the Asymmetric-Paths Winding by Novel Combinatorial Approach

IEEE Access, 2019
This paper proposes a novel combinatorial approach for the optimization design of the asymmetric-paths winding, to solve the design contradiction between the asymmetric degree and the tidiness of end connections.

Entanglement and quantum combinatorial designs

, 2018
We introduce several classes of quantum combinatorial designs, namely quantum Latin squares, cubes, hypercubes and a notion of orthogonality between them. A further introduced notion, quantum orthogonal arrays, generalizes all previous classes of designs.

On quasi-orthogonal cocycles [PDF]

, 2017
We introduce the notion of quasi-orthogonal cocycle. This is motivated in part by the maximal determinant problem for square {±1}-matrices of size congruent to 2 modulo 4. Quasi-orthogonal cocycles are analogous to the orthogonal cocycles of algebraic

DeviceEditor visual biological CAD canvas

Journal of Biological Engineering, 2012
Background Biological Computer Aided Design (bioCAD) assists the de novo design and selection of existing genetic components to achieve a desired biological activity, as part of an integrated design-build-test cycle.

Methodology for Automated Design of Quantum-Dot Cellular Automata Circuits

IEEE Open Journal of Nanotechnology, 2023
Quantum-dot Cellular Automata (QCA) provide very high scale integration potential, very high switching frequency, and have extremely low power demands, which make the QCA technology quite attractive for the design and implementation of large-scale, high ...
