UFOs in the LHC: Observations, studies and extrapolations
Unidentified falling objects (UFOs) are potentially a major luminosity limitation for nominal LHC operation. They are presumably micrometer sized dust particles which lead to fast beam losses when they interact with the beam. With large-scale increases and optimizations of the beam loss monitor (BLM) thresholds, their impact on LHC availability was mitigated from mid 2011 onwards. For higher beam energy and lower magnet quench limits, the problem is expected to be considerably worse, though. In 2011/12, the diagnostics for UFO events were significantly improved: dedicated experiments and measurements in the LHC and in the laboratory were made and complemented by FLUKA simulations and theore…
Are gut hormones responsible for the decrease of appetitive behaviour for sweet and fatty foods after gastric bypass surgery?
WOS: 000321389200211; International audience; Introduction: Gastric bypass surgery (RYGB) decreases preference for sweet and fatty foods, but the underlying mechanism is not known. This study aimed to investigate the role of the exaggerated satiety gut hormone release on appetitive reward of sweet and fatty taste after RYGB. Method: 13 patients that have undergone previous RYGB surgery (>6 months) and 13 normal weight controls participated in a double-blind placebo-controlled trial comparing the effect of subcutaneous injections of somatostatin analogue (octreotide) which blocks satiety gut hormone responses, and saline (control) on the appetitive reward value of sweet-fat candies. Appetiti…
