Presentations of Cluster Modular Groups and Generation by Cluster Dehn Twists [PDF]

open access: yes, 2020
We give a method to compute presentations of saturated cluster modular groups. Using this, we obtain finite presentations of the saturated cluster modular groups of finite mutation type $X_6$ and $X_7$. We verify that the cluster modular groups of finite

Modular Lightning Protection for Wind Turbines

open access: yesWind, 2023
Wind energy holds a leading position among other renewable energy sources in electricity production. The competitive advantage of wind turbines to be connected to every electrical grid around the world and the 2030 targets of the EU have led to their ...

Reconfiguration of a Bus Chassis Module Using the Digital Expression for Connectivity between Module Interfaces

open access: yesApplied Sciences, 2022
Modular design for a bus chassis is a practical solution to address different bus types and their differing powertrains. Physics interfaces are used to connect interacting subsystems in bus chassis modules.

Vector valued hermitian and quaternionic modular forms [PDF]

open access: yes, 2014
Extending the method of the paper [FS3] we prove three structure theorems for vector valued modular forms, where two correspond to 4-dimensional cases (two hermitian modular groups, one belonging to the field of Eisenstein numbers, the other to the field

Force-controlled pose optimization and trajectory planning for chained Stewart platforms

open access: yesFrontiers in Mechanical Engineering, 2023
Introduction: We study optimization methods for poses and movements of chained Stewart platforms (SPs) that we call an “Assembler” Robot. These chained SPs are parallel mechanisms that are stronger, stiffer, and more precise, on average, than their ...

Mycobacterium tuberculosis strains from ancient and modern lineages induce distinct patterns of immune responses

open access: yesJournal of Infection in Developing Countries, 2018
Introduction: It is possible that the difference in virulence and prevalence of different strains of Mycobacterium tuberculosis is related to the diverse immune response they evoke in the host.

Dual Modular Soft Robot with Multi-Terrain Movement Ability

open access: yesShanghai Jiaotong Daxue xuebao, 2022
Aimed at the problems of limited application range, single movement scene, inability of climbing, and limited space movement of the multi-terrain movement robot, a novel dual module soft robot with the multi-terrain movement ability is proposed.

Battling adhesions: from understanding to prevention

open access: yesBMC Biomedical Engineering, 2019
Adhesions represent a major burden in clinical practice, particularly following abdominal, intrauterine, pericardial and tendon surgical procedures. Adhesions are initiated by a disruption in the epithelial or mesothelial layer of tissue, which leads to ...

Modular Curves, Modular Surfaces and Modular Fourfolds [PDF]

open access: yes, 2007
This article surveys some recent work of the author on Hilbert modular fourfolds X. After some preliminaries on the cohomology and special, codimension 2 cycles Z on X of Hirzebruch-Zagier type, a proof of the Tate conjecture for X over abelian fields is exposed. It is followed by a description of a method to construct classes in the Bloch's Chow group

2-Modular Matrices

open access: yesSIAM Journal on Discrete Mathematics, 2022
A rank-$r$ integer matrix $A$ is $Δ$-modular if the determinant of each $r \times r$ submatrix has absolute value at most $Δ$. The class of $1$-modular, or unimodular, matrices is of fundamental significance in both integer programming theory and matroid theory.
