  • S3 Dorsal Root Ganglion/Nerve Root Stimulation for Refractory Postsurgical Perineal Pain: Technical Aspects of Anchorless Sacral Transforaminal Lead Placement
    Case reports in neurological medicine, 2016
    Co-Authors: Xander Zuidema, Jennifer Breel, F. Wille
    Abstract:

    Chronic perineal pain limits patients in physical and sexual activities, leading to social and psychological distress. In most cases, this pain develops after surgery in the urogenital area or as a consequence of trauma. Neuromodulation is one of the options in chronic postsurgical perineal pain treatment. We present a case of refractory perineal pain after right sided surgical resection of a Bartholin's cyst which was treated with third sacral nerve root/dorsal root ganglion stimulation using the transforaminal approach. We describe a new anchorless lead Placement Technique using a unique curved lead delivery sheath. We postulate that this new posterior foraminal Technique of lead Placement is simple, safe, and reversible and may lower the occurrence of lead related complications.

  • influence of Placement Techniques on vickers and knoop hardness of class ii composite resin restorations
    Dental Materials, 2004
    Co-Authors: Laiza Tatiana Poskus, Eliane Placido, Paulo Eduardo Capel Cardoso
    Abstract:

    Abstract Objectives. To analyze the influence of two Placement Techniques on Knoop and Vickers hardness of class II cavities restored using packable (A.L.E.R.T., Solitaire 2, SureFil) and conventional microfilled and hybrid (Filtek A110 and Z250, respectively) resin composites. Methods. Fifty standardized class II cavities (5×3×1.5 mm3) were prepared in human premolars. They were divided into ten groups (n=5) and restored according to each resin composite material (A.L.E.R.T., Solitaire 2, SureFil, Filtek A110 and Z250) and Placement Technique (incremental or bulk). After storage in distilled water at 37 °C for 24 h, they were thermal cycled (700 cycles/5–55 °C, 1 min dwell time) and sectioned longitudinally. One section from each specimen was embedded and polished for Knoop and Vickers hardness measurements. Sixteen indentations were performed for each restoration, eight on the occlusal and eight on the cervical surfaces. Results. Results were submitted to ANOVA and demonstrated that all materials presented lower hardness values at the cervical surfaces when the bulk Placement Technique was employed, when compared to the occlusal surfaces (p Significance. The use of bulk Placement Technique resulted in lower values of hardness at the cervical surfaces of class II restorations. Values obtained using Knoop hardness test showed a high correlation with Vickers hardness measurements.

  • impact of graph partitioning on snn Placement for a multi core neuromorphic architecture work in progress
    Compilers Architecture and Synthesis for Embedded Systems, 2018
    Co-Authors: Francesco Barchi, Gianvito Urgese, Enrico Macii, Andrea Acquaviva
    Abstract:

    In this paper, we evaluate a partitioning and Placement Technique for mapping concurrent applications over a globally asynchronous locally synchronous (GALS) multi-core architecture designed for simulating a spiking neural network (SNN) in real-time. We designed a task Placement pipeline capable of analysing the network of neurons and producing a Placement configuration that enables a reduction of communication between computational nodes. The neuron-to-core mapping problem has been formalised as a two phases problem: Partitioning and Placement. The Partitioning phase aims at grouping together the most connected network components, maximising the amount of self-connections within each identified group. For this purpose we used a multilevel k-way graph partitioning strategy capable of generating network-partitions. The Placement phase aims at placing groups of neurons over the chip mesh minimising the communication between computational nodes. For implementing this step, we designed and evaluate the performances of three Placement variants. In the results, we point out the importance of using a partitioning algorithm for the SNN graph. We were able to achieve an increase in self-connections of 19% and an improvement of the final overall post-Placement synaptic elongation of 29% using the simulated annealing Placement Technique, compared to 22% obtained without partitioning.
