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

open access: yesPhysics 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 ...

Case Report: An Unusual Case of Fasciculoventricular Pathway

open access: yesFrontiers in Cardiovascular Medicine, 2022
A 30-year-old man with an ECG demonstrating ventricular preexcitation with a normal PR interval and a QR pattern in lead V1 was evaluated. Electrophysiology studies showed a normal AH interval and a shortened HV interval at sinus rhythm; while the degree

Transient complete heart block following catheter ablation of a left lateral accessory pathway. [PDF]

open access: yes, 2019
A 16-year-old female with symptomatic Wolff-Parkinson-White (WPW) syndrome underwent catheter ablation of a left-sided lateral accessory pathway. The accessory pathway was eliminated with the first ablation lesion; however, the patient immediately ...

Contact force sensing in ablation of ventricular arrhythmias using a 56-hole open-irrigation catheter: a propensity-matched analysis. [PDF]

open access: yes, 2021
PURPOSE: The effect of adding contact force (CF) sensing to 56-hole tip irrigation in ventricular arrhythmia (VA) ablation has not been previously studied.

Osteopontin ablation ameliorates muscular dystrophy by shifting macrophages to a pro-regenerative phenotype. [PDF]

open access: yes, 2016
In the degenerative disease Duchenne muscular dystrophy, inflammatory cells enter muscles in response to repetitive muscle damage. Immune factors are required for muscle regeneration, but chronic inflammation creates a profibrotic milieu that exacerbates

"Properties of lightweight, ablation and thermal insulation materials

open access: yesHecheng xiangjiao gongye, 2022
Methyl vinyl silicone rubber and methyl vinyl phenyl silicone rubber were used as the matrix, silica and boron phenolic resin (BF) were added for mixing, a light ablative heat insulation material was prepared. The density of the heat insulation material,

Radiofrequency Ablation for Post Infarction Ventricular Tachycardia [PDF]

open access: yes, 2004
Radiofrequency ablation has an important role in the management of post infarction ventricular tachycardia. The mapping and ablation of ventricular tachycardia (VT) is complex and technically challenging.

Controlled Irradiative Formation of Penitentes

open access: yes, 2006
Spike-shaped structures are produced by light-driven ablation in very different contexts. Penitentes 1-4 m high are common on Andean glaciers, where their formation changes glacier dynamics and hydrology.

Sub-debris melt rates on southern Inylchek Glacier, central Tian Shan [PDF]

open access: yes, 2008
Melt rates of glacier surfaces are strongly influenced by the existence of a debris cover. Dependent on thickness and other physical parameters the debris layer can enhance or reduce ablation as compared to bare ice conditions.

Long-Term Follow-Up of Cardioneuroablation to Treat Second-Degree Block After Slow Pathway Ablation

open access: yesJACC: Case Reports, 2020
We present the long-term follow-up of a 31-year-old woman who underwent cardioneuroablation (for atrioventricular (AV) block. Slow pathway ablation was performed in September 2017 with normal follow-up until April 2018, when the patient started noticing ...
