, 2003 We study the properties and phenomenology of particle-like states originating from D-branes whose spatial dimensions are all compactified. They are non-perturbative states in string theory and we refer to them as D-matter.

Study on Drill String Stick-slip Vibration Pattern Under Bit-Rock Interaction
Shiyou jixie, 2023 Stick-slip vibration leads to high-frequency shear stress on drill string and premature fatigue of drill string.Therefor,the torsional vibration model of drill string system considering bit-rock interaction was built by coupling the bit-rock interaction ...

Numerical study of critical properties and hidden orders in dimerized spin ladders [PDF]
, 2011 Dimerized antiferromagnetic spin-1/2 ladders are known to exhibit a quantum critical phase transition in the ground state, the existence or absence of which is dependent on the dimerization pattern of the ladder. The gapped phases cannot be distinguished

String patterns in the doped Hubbard model [PDF]
Science, 2019 Looking for patterns in an optical lattice One of the simplest models of interacting fermions on a two-dimensional (2D) lattice—the Hubbard model—becomes too tricky to simulate on classical computers as the density of empty lattice sites (holes) increases. Chiu et al.

BIOS, 2020 String matching is an algorithm for matching a text to another text or also known as a text search. There are several algorithms that can be used for string matching, including the Boyer-Moore algorithm and the Brute Force algorithm.

MODEL OF CHARACTER STRING IN PATTERN RECOGNITION BASED ON STRUCTURAL METHODS
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019 The proposed model of the character string allows to determine its degree of compliance of the formal grammar. The model can be used for pattern recognition and image processing based on syntactic techniques when the character string is not derived by ...

String-Inspired Triplet See-Saw from Diagonal Embedding of SU(2)_L in SU(2)_A x SU(2)_B
, 2005 Motivated by string constructions, we consider a variant on the Type II see-saw mechanism involving the exchange of triplet representations of SU(2)_L in which this group arises from a diagonal embedding into SU(2)_A x SU(2)_B.

A Comparative Study of Sparse Associative Memories
, 2016 We study various models of associative memories with sparse information, i.e. a pattern to be stored is a random string of $0$s and $1$s with about $\log N$ $1$s, only. We compare different synaptic weights, architectures and retrieval mechanisms to shed
