This study assessed the incidence of mild, moderate and severe adverse events (AEs) and examined their association with age, sex, body region examined, time to event and duration of the AE(s) in a large cohort of patients who underwent contrast-enhanced ultrasound (CEUS) with Lumason/SonoVue. In this retrospective observational study, 49,100 patients who underwent CEUS were analyzed. Forty-three (0.088%) patients experienced AEs, with 23 (0.047%) patients experiencing mild AEs, 13 (0.026%) experiencing moderate AEs and 7 (0.014%) experiencing severe AEs. No fatal event occurred. There was no age- or sex-related difference in the incidence of the AE(s) (p = 0.158 and p = 0.474). Inpatients (0.17%) more often experienced AEs than outpatients (0.06%, p = 0.003). The mean time to event for mild and moderate AEs was 14.50 ± 6.96 and 15.75 ± 10.40 min, respectively, whereas that for severe AEs was 1.89 ± 1.21 min after the injection. The remission time for mild and moderate AEs was approximately 30-40 min, and all patients with severe AEs recovered within 12 h. Twenty-one (48.8%) patients received medical treatment. In summary, Lumason/SonoVue has a good safety profile with a low incidence of AEs, most of which are mild with a short time to event and duration.

A photovoltaic photodetector based on a hybrid dimensional WSe2/WS2/p-Si dual-vdW heterojunction is constructed, which can realize the coupling of the photovoltaic effect and photogating effect.

Device structure, photoresponsivity, diverse modes regulated photoresponse and high-resolution imaging based on van der Waals semimetal PtTe2/semiconductor MoTe2 junctions.

High-performance visible and near-infrared photodetection and single-pixel imaging can be achieved by our γ-InSe/Ge photodiode at zero bias. Meanwhile, a maximum polarization sensitivity of 3.01 is obtained under 635 nm among the broadband spectrum.

The band structure of a heterojunction significantly affects its photocharge separation efficiency.

A device with a gate length less than 3 nm has a low subthreshold swing, fast switching speeds, and low switching energies, and the related parameters can simultaneously satisfy the ITRS in 2028.

In this paper, we design a metasurface terahertz perfect absorber with multi-frequency selectivity and good incident angle compatibility using a double-squared open ring structure. Simulations reveal five selective absorption peaks located at 0-1.2 THz with absorption 94.50% at 0.366 THz, 99.99% at 0.507 THz, 95.65% at 0.836 THz, 98.80% at 0.996 THz, and 86.70% at 1.101 THz, caused by two resonant absorptions within the fundamental unit (fundamental mode of resonance absorption, FRA) and its adjacent unit (supermodel of resonance absorption, SRA) in the structure, respectively, when the electric field of the electromagnetic wave is incident perpendicular to the opening. The strong frequency selectivity at 0.836 THz with a
