rounded insertion technique for cochlear implantation surgery to treat cystic inner ear malformation
Laryngoscope, 2019Co-Authors: Haochun Hu, William Kuanhua Chen, Meijui Huang, Joshua Kuangchao ChenAbstract:OBJECTIVE: This article outlines the advantages and applicability of the rounded insertion technique of cochlear implants in patients with cystic inner ear malformation. This technique enables the insertion of the maximum number of electrodes and prevents the unwanted entry of electrodes into the internal auditory canal. METHODS: We conducted a retrospective chart review of consecutive patients with cochlear hypoplasia (CH) and/or common cavity (CC) who underwent CI (cochlear implantation) via rounded insertion technique. The position of the electrode array in each patient was confirmed postoperatively via X-ray, and the number of functional electrodes was confirmed during the Mapping Process. RESULTS: This study included five male and two female patients (median age: 3 years; age range: 2-7 years). Among the seven patients, four received a cochlear implant on the right side, one on the left side, and two bilaterally. Of the nine ears, six were cases of CH, and three were CC. All cochlear implant surgeries via rounded insertion technique were completed without complications. The maximum number of electrode contacts with fair function in the cystic cochlea was confirmed via postoperative X-ray and the subsequent Mapping Process. CONCLUSION: This consecutive series of patients demonstrated the safety and reliability of rounded insertion technique for CI in patients with CH and/or CC. LEVEL OF EVIDENCE: 4 Laryngoscope, 2019.

on chip power supply network optimization using multigrid based technique
Design Automation Conference, 2003Co-Authors: Kai Wang, Malgorzata MareksadowskaAbstract:In this paper, we present a novel multigrid-based technique for on-chip power supply network optimization. We reduce a large-scale network to a much coarser one which can be efficiently optimized. The solution for the original network is then quickly computed using a back-Mapping Process. We model the power grid by an RLC network and use time-varying current sources to capture the on-chip switching. Our technique is capable of optimizing power grid and decoupling capacitance simultaneously. Experimental results show that the proposed technique provides more robust and area-efficient solutions than those obtained by the earlier approaches. It also provides a significant speed-up and brings up a possibility of incorporating power supply network optimization into other physical design stages such as signal routing.

On-chip power-supply network optimization using multigrid-based technique
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2005Co-Authors: Kai Wang, M. Marek-sadowskaAbstract:In this paper, we present a novel multigrid-based technique for the problem of on-chip power-supply network optimization. The multigrid-based technique is applied to reduce a large-scale network to a much coarser one. The reduced network can be efficiently optimized. The solution for the original network is then quickly computed using a back-Mapping Process. Due to the adoption of an accurate resistance-inductance-capacitance power-supply network and time-varying switching-current model, our technique is capable of optimizing power grid and decoupling capacitance simultaneously. Experimental results show that large-scale power-supply networks with millions of nodes can be solved in a few minutes. The proposed technique not only speeds up significantly the optimization Process, without compromising the quality of solutions, but also brings up a possibility of incorporating the power-supply network optimization into other physical design stages such as signal routing.
