Junction‐Controlled Topological Polymerization
Angewandte Chemie International Edition, 2018AbstractMethodology that enables the controlled synthesis of linear and branched polymers from an identical monomer will be a novel pathway for polymer synthesis and processing. Herein we first describe the control of one or both of the C(3)‐C(3′) and C(6)‐C(6′) coupling reactions of carbazolyl. In a second approach, an identical monomer containing two

Controlled topology simplification
IEEE Transactions on Visualization and Computer Graphics, 1996We present a simple, robust, and practical method for object simplification for applications where gradual elimination of high frequency details is desired. This is accomplished by converting an object into multi resolution volume rasters using a controlled filtering and sampling technique.

Computer-Aided Design, 2006
Many applications require the extraction of isolines and isosurfaces from scalar functions defined on regular grids. These scalar functions may have many different origins: from MRI and CT scan data to terrain data or results of a simulation. As a result of noise and other artifacts, curves and surfaces obtained by standard extraction algorithms often ...

Topological Optics Controlling the topological properties of physical systems provides a platform for developing devices and technology that are robust to defects. Xia et al. present a photonic platform in which the underlying dynamics are driven and tuned by the interplay among topology, non-Hermiticity, and nonlinearity (see the Perspective by ...

Proceedings of the 7th ACM international symposium on Mobile ad hoc networking and computing, 2006
To date, topology control in wireless ad hoc and sensor networks--the study of how to compute from the given communication network a subgraph with certain beneficial properties .has been considered as a static problem only; the time required to actually schedule the links of a computed topology without message collision was generally ignored.

2004 IEEE Wireless Communications and Networking Conference (IEEE Cat. No.04TH8733), 2004
We deal with the problem of topology control for mobile ad hoc networks. Based on an asymptotic result on k-connectivity, a simple scheme for topology control is proposed. The scheme is used to generate several topologies under highly mobile conditions.

Topological analysis of metabolic control
Mathematical Biosciences, 1990A topological approach is presented for the analysis of control and regulation in metabolic pathways. In this approach, the control structure of a metabolic pathway is represented by a weighted directed graph. From an inspection of the topology of the graph, the control coefficients of the enzymes are evaluated in a heuristic manner in terms of the ...

Topologically Controlled Interpolyelectrolyte Complexes
Macromolecules, 2008The complexation of a cylindrical polyelectrolyte−brush−surfactant complex (PMMPSS−C12) and an oppositely, highly charged cylindrical polyelectrolyte−brush (PMMPEI−PEO) in dimethylformamide (DMF) l...

Topologized variables and controls
2001 European Control Conference (ECC), 2001Presented is a theoretical framework for variables and their control taking approximate behavior ("fuzziness") into account. In our definition of variables the domain of a variable is parameterized by control parameters, the theoretical concepts used are from classical topology.

Robust Topology Control Protocols
2005Topology control protocols attempt to reduce the energy consumption of nodes in an ad-hoc wireless network while maintaining sufficient network connectivity. Topology control protocols with various features have been proposed, but they all lack robustness and are extremely sensitive to faulty information from neighbors. For example, the XTC protocol (R.
