In-water lidar simulations: the ALADIN ADM-Aeolus backscattered signal at 355 nm.

The Lidar Ocean Color (LiOC) Monte Carlo code has been developed to simulate the in-water propagation of the lidar beam emitted by the ALADIN ADM-Aeolus instrument in the ultraviolet (UV) spectral region (∼ 355 nm). To this end, LiOC accounts for reflection/transmission processes at the sea surface, absorption and multiple scattering in the water volume, and reflection from the sea bottom. The water volume components included in the model are pure seawater, Chlorophyll-a concentration (Chl-a), Colored Dissolved Organic Matter (CDOM), and/or a generic absorbing species.

Radiative transfer simulations of water-leaving radiance from the Skylight-Blocked Approach.

Radiative transfer simulations of measurements performed with the Skylight-Blocked Approach (SBA) for water exhibiting diverse optical properties confirmed the non-negligible impact of the depth z of the radiometer shield in the determination of the water-leaving radiance L. In particular, results showed that the shield-shaded water volume lowers the measured L value by a few up to tens of percent as a function of the depth z, water attenuation, and wavelength. The study also confirmed the potential applicability of an analytical correction scheme based on the sole water absorption and backscattering coefficients to support operational SBA measurements, still at the expense of decreased accuracy with increasing depth z and water turbidity.

Successful surgical treatment for primary cardiac angiosarcoma: a case report.

Background: Primary cardiac angiosarcomas are extremely rare and their prognosis is poor. Surgical resection is the first-line treatment; however, no clear standard of care has been clearly established because of the rarity of these tumors.

Case Presentation: A 61-year-old man who had presented with dyspnea on exertion was referred to our hospital.
