Effi cient Nanosecond Pulse Amplifi cation Using Transverse-Flow Carbon Dioxide Lasers

Effi cient Estimation using the Characteristic Function∗

The method of moments proposed by Carrasco and Florens (2000) permits to fully exploit the information contained in the characteristic function and yields an estimator which is asymptotically as effi cient as the maximum likelihood estimator. However, this estimation procedure depends on a regularization or tuning parameter α that needs to be selected. The aim of the present paper is to provide...

Aesthetic Depigmentation of Gingival Smoker's Melanosis Using Carbon Dioxide Lasers

Melanic pigmentation results from melanin produced by the melanocytes present in the basal layer of the oral epithelium. One of the most common causes of oral pigmentation is smoker melanosis, a condition associated with the melanocyte stimulation caused by cigarette smoke. This paper aims to illustrate the use of a carbon dioxide laser in the removal of the gingival melanic pigmentation for ae...

Will Sub-Nanosecond Lasers Replace Nanosecond Lasers for Tattoo Removal?

With their short nanosecond pulse durations, Qswitched lasers have revolutionized the treatment of tattoos [1-3]. Nevertheless, the mechanisms for clinically observed tattoo clearance are still not well understood. Two mechanisms have been proposed: a) a thermal effect where tattoo particles are heated to sufficiently high temperatures to cause chemical changes within the particles and the surr...

Effi cient High - Dimensional , Edge - Aware Filtering

Surplus Division and Effi cient Matching

We study a two-sided matching model with a finite number of agents and with transferable utility: agents on both sides of the market are privately informed about multi-dimensional attributes that determine the match value of each pair. Utility functions are assumed to be quasi-linear, and monetary transfers among agents are feasible. We ask the following question: what divisions of surplus amon...
