Ablation of solids by femtosecond lasers: ablation mechanism and ablation thresholds for metals and dielectrics [PDF]

Physics of Plasmas, 2001
The mechanism of ablation of solids by intense femtosecond laser pulses is described in an explicit analytical form. It is shown that at high intensities when the ionization of the target material is complete before the end of the pulse, the ablation ...

Volumetric Quantitative Ablation Margins for Assessment of Ablation Completeness in Thermal Ablation of Liver Tumors [PDF]

Frontiers in Oncology, 2021
BackgroundIn thermal ablation of liver tumors, complete coverage of the tumor volume by the ablation volume with a sufficient ablation margin is the most important factor for treatment success. Evaluation of ablation completeness is commonly performed by visual inspection in 2D and is prone to inter-reader variability.

Ablation technologies

Surgery Open Science, 2022
Ablative therapies have recently emerged as an alternate to the gold-standard liver resection in treatment of malignant liver tumors. These modalities include radiofrequency ablation and microwave ablation which utilize thermocoagulative energy and microwave energy, respectively, to create a complete necrosis zone encircling the lesion. In this review,

Non-Equilibrium Ablation of Phenolic Impregnated Carbon Ablator [PDF]

48th AIAA Aerospace Sciences Meeting Including the New Horizons Forum and Aerospace Exposition, 2010
In previous work, an equilibrium ablation and thermal response model for Phenolic Impregnated Carbon Ablator was developed. In general, over a wide range of test conditions, model predictions compared well with arcjet data for surface recession, surface temperature, in-depth temperature at multiple thermocouples, and char depth.

Early Repolarization Syndrome: Diagnostic and Therapeutic Approach

Frontiers in Cardiovascular Medicine, 2018
An early repolarization pattern can be observed in 1% up to 13% of the overall population. Whereas, this pattern was associated with a benign outcome for many years, several more recent studies demonstrated an association between early repolarization and

Recurrence and additional treatment of cystic thyroid nodules after ethanol ablation: validation of three proposed criteria [PDF]

Ultrasonography, 2021
Purpose We evaluated the use of three criteria to determine the need for additional treatment of cystic thyroid nodules after their recurrence following ethanol ablation (EA).

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]

, 2012
Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.

To ablate or not to ablate? HSCs in the T cell driver’s seat [PDF]

Journal of Clinical Investigation, 2007
The combination of the induction of lymphopenia and vaccination and/or T cell transfer is garnering much attention for cancer treatment. Preclinical studies have shown that the induction of lymphopenia by chemotherapy or radiation can enhance the antitumor efficacy of several distinct, cell-based immunotherapeutic approaches.

Characterization of Atrial Septal Defect Occluders by right and left atrial pull-out forces

Current Directions in Biomedical Engineering, 2019
Occluders made of the shape memory alloy Nitinol are commonly used to close Atrial Septal Defects (ASD). Until now, standard parameters are missing defining the mechanical properties of these implants.

Ultrasound-guided ethanol ablation for cystic thyroid nodules: effectiveness of small amounts of ethanol in a single session [PDF]

Ultrasonography, 2021
Purpose The aim of this study was to evaluate the efficacy of ethanol ablation (EA) in the treatment of cystic thyroid nodules using low-dose ethanol regardless of the initial volume of the nodule or properties of the aspirate.
