Optical traps or "tweezers" use high-power, near-infrared laser beams to manipulate and apply forces to biological systems, ranging from individual molecules to cells. Although previous studies have established that optical tweezers induce photodamage in live cells, the effects of trap irradiation have yet to be examined in vitro, at the single-molecule level. In this study, we investigate trap...

The L’Aquila earthquake of magnitude 5.8 occurred on April 6, 2009 in the central Abruzzo region of Italy, causing widespread damage. More than 300 people lost their lives and property worth more than 2,500 million dollars was damaged. We analyze the high-resolution Synthetic Radar Aperture (SAR) imageries from TerraSAR-X along with high-resolution QuickBird optical images for the building dama...

With the unceasing exploitation of gas fields, casing damage is an important element which restrict oil-gas throughput. In this paper we present an distributed optical fiber Bragg grating analysical method in the Real-time Casing Damage Monitoring Work which through the study of the main type and damage of casing damage, analysis and comparison of the casing damage monitoring method, responding...

OBJECTIVE To describe the features and incidence of epiretinal traction and related retinal damage in degenerative myopia. DESIGN Consecutive observational case series. METHODS We retrospectively reviewed medical records and optical coherence tomography findings of 218 eyes with high myopia of 121 consecutive patients to detect the incidence and features of epiretinal traction-related macul...

A nonlinear mathematical model was developed and experimentally validated to investigate the effects of changes in optical properties during interstitial laser photocoagulation (ILP). The effects of dynamic optical properties were calculated using the Arrhenius damage model, resulting in a nonlinear optothermal response. This response was experimentally validated by measuring the temperature ri...

While silicon has several properties making it an attractive material for structure-based laser-driven acceleration, its optical damage threshold, a key parameter for high-gradient acceleration, has been unknown. Here we present measurements of the optical damage threshold of crystalline silicon for ultrafast pulses in the mid-infrared. The wavelengths tested span a range from the telecommunica...
