Inconel 718 is considered difficult to machine because of its ability maintain properties at high temperatures. The low thermal conductivity the alloy causes accelerated tool deterioration when machining. Selective laser melting (SLM) additive manufacturing introduces a possibility eliminating these difficulties, and producing complex shapes with this difficult-to-machine material. However, sur...

A recently developed model, which is very successful in explaining pulse duration and spot size dependences of Ž . Ž . Ž . w nanosecond laser ablation rates of polyimide PI and poly methyl methacrylate PMMA H. Schmidt, J. Ihlemann, B. Ž . x Wolff-Rottke, K. Luther, J. Troe, J. Appl. Phys., 83 1998 5458. , is applied to calculate the temporal behavior of position and temperature of the moving in...

BACKGROUND A robotic catheter navigation system has been developed that provides a significant degree of freedom of catheter movement. This study examines the feasibility of synchronizing this robotic navigation system with electroanatomic mapping and 3-dimensional computed tomography imaging to perform view-synchronized left atrial (LA) ablation. METHODS AND RESULTS This study consisted of a...

The surface and basal boundary conditions exert an important control on the thermodynamic state of the Greenland Ice Sheet, but their representation in numerical ice sheet models is poorly constrained due to the lack of observations. Here we investigate a land-terminating sector of western Greenland and (1) quantify differences between new observations and commonly used boundary condition data ...

Background: Irreversible electroporation (IRE) is a novel tumor ablation technique. IRE is associated with high electrical fields and is often reported in conjunction with thermal damage caused by Joule heating. For good response to surgery it is crucial to produce minimum thermal damage in both tumoral and healthy tissues named Non-Thermal Irreversible Electroporation(NTIRE). Non-thermal irrev...
