    “…A series of reliability tests were conducted on the phosphor films and bare phosphors: high-temperature and high-humidity (HT) tests, thermal-cycling (TC) tests, and xenon lamp aging (XLG) tests. Then, the crystal phase, surface morphology, photoluminescence (PL), afterglow decay, and temperature-dependent PL were analyzed. …”

    “…At a pyrite dosage of 0.1 g L(−1), CA concentration of 0.6 mM and an initial pH of 6.0, the degradation efficiency of APAP (30 μM) was 99.1% within 30 min under the irradiation of xenon lamp (70 W, λ ≥ 350 nm). Almost the same high efficiency of APAP degradation (93.9%) in the system was achieved under natural sunlight irradiation (ca. 650 W m(−2)). …”

    “…Ghost charge results measured via the BGI technique are reported, including the first such measurements made with the VELO subdetector in its open position and with the first xenon beams circulating in the LHC. The utility of the LHCb measurement as a cross-check on measurements from LHC instrumentation is demonstrated and a novel timing technique making use of the LHCb Outer Tracker is set out. …”

    “…In this narrative review, we draw the picture of the current state of knowledge in anesthesia-induced unconsciousness, from insights gathered on propofol, halogenated vapors, ketamine, dexmedetomidine, benzodiazepines and xenon. We also describe how anesthesia can help understanding consciousness, we develop the above-mentioned unresolved questions, and propose tracks for future research.…”

    “…In our study cohort, we noted no intraoperative issues and deterioration in clinical status following the use of volatile anesthetic agents, opioids, dexmedetomidine, and propofol for general anesthesia (GA) or sedation. As ketamine, xenon, and N(2)O mediate their anesthetic effects, primarily, through antagonism of NMDA receptors, theoretical concerns suggest that they should be avoided.…”

    “…Two-point thresholds were determined by measuring the minimum distance between two points of broadband xenon light. RESULTS: The photochromic contact lens produced smaller halo diameters than the control contact lens, both activated (41% on average) and inactivated (21% on average), and age strata was a significant factor (P<0.001) with the older group showing a greater reduction. …”

    “…This light can be generated by mercury-vapour, light-emitting diode (LED), pulsed-xenon, or excimer lamps. Multiple factors are detrimental to disinfection performance such as shadowing, a rough surface topography, a high level of contamination, repair mechanisms, and the lack of standardization. …”
