Ablation thresholds and ash thickness

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

Comparison of holmium:YAG and thulium fiber laser lithotripsy: ablation thresholds, ablation rates, and retropulsion effects.

The holmium:YAG (Ho:YAG) laser lithotriptor is capable of operating at high pulse energies, but efficient operation is limited to low pulse rates (∼10 Hz) during lithotripsy. On the contrary, the thulium fiber laser (TFL) is limited to low pulse energies, but can operate efficiently at high pulse rates (up to 1000 Hz). This study compares stone ablation threshold, ablation rate, and retropulsio...

Epicardial Adipose Tissue Thickness and Ablation Outcome of Atrial Fibrillation

OBJECTIVES Epicardial fat was closely related to atrial fibrillation (AF). Transthoracic echocardiography (TTE) has been proposed to be a convenient imaging tool in assessing epicardial adipose tissue (EAT). The goal of the present study was to investigate whether the EAT thickness measured on TTE was a useful parameter in predicting procedural outcomes of AF ablations. METHODS AND RESULTS A ...

Oligopoly with Capacity Constraints and Thresholds

    Abstract   Extended Oligopoly models will be introduced and examined in which the firms might face capacity limits, thresholds for minimal and maximal moves, and antitrust thresholds in the case of partial cooperation. Similar situation occurs when there is an additional cost of output adjustment, which is discontinuous at zero due to set-up costs. In these cases the payoff functions of the...

Thresholds and Expectation Thresholds

(See e.g. [2], [6] or [18]. Of course p0(n) is not quite unique, but following common practice we will often say “the” threshold when we should really say “a.”) It follows from [8] that every {Fn} has a threshold, and that in fact (see e.g. [18, Proposition 1.23 and Theorem 1.24]) p0(n) := pc(Fn) is a threshold for {Fn}. So the quantity pc conveniently captures threshold behavior, in particular...
