Abstract: A method is provided for detecting a fluorescent species that is reversibly photoswitchable at high frequency, and more precisely to a method for detecting at least one reversibly photoswitchable fluorescent species, including a step consisting in illuminating a sample containing a reversibly photoswitchable fluorescent species with a first illuminating light beam, of wavelength ?1, and periodically modulated at an angular frequency ?, and with a second illuminating light beam of wavelength ?2 different from ?1, which is periodically modulated at the angular frequency ?, the second illuminating light beam being modulated in antiphase with respect to the first illuminating light beam.

Abstract: A dispenser for dispensing sheet products includes a plurality of walls connected to each other, defining an interior volume, and a stack of sheet products received in the interior volume. A removable panel is provided at a top wall of the plurality of walls. The dispenser is configured so that, upon removal of the removable panel, an opening in the top wall for removing sheet products is revealed. The dispenser has a firmness in the range of 20 to 140, in particular, 70 to 90.

Abstract: Method of sequestration of carbon dioxide characterized in that it comprises: a step of production of at least one macrophyte plant species floating on an expanse of fresh water in order to form a raft of plant biomass; a step of transportation of said raft of plant biomass from said expanse of fresh water to a sea; a step of dispersal and decomposition of said raft of plant biomass on an expanse of said sea; at least one of said step of production, said step of transportation and said step of dispersal and decomposition being carried out with human assistance.

Abstract: A method for detection of at least one reversibly photo-convertible fluorescent species, comprises the following steps: a) illumination of a sample comprising said or at least one of the reversibly photo-convertible fluorescent species by a periodically modulated illuminating light; and b) detection of fluorescent emission emitted by the sample thus illuminated; wherein the method further comprises the following step: c) extraction of the amplitude of the intensity component of the fluorescent emission exhibiting the same periodicity as the periodically modulated illuminating light and a phase quadrature with respect to the same; and wherein the mean intensity of the illuminating light and the modulation frequency of the same are chosen to maximize the amplitude of the intensity component of the fluorescent emission.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for providing content management features in a messaging service. A messaging client receives a reference to a content item stored on a content management system and receives, from the content management system, a set of sharing options for the content item. The set of sharing options is presented to the user via the messaging client and a user selection of sharing options is received. The messaging client sends the user selection of sharing options to the content management system, wherein the content management system is configured to apply the user selection of sharing options to the content item.

Abstract: A method and system are provided for acquiring and combining images captured by a microscope. The method comprises: capturing a new image from the microscope using an imaging device; comparing the new image against a previous image to provide an estimated position of the new image; identifying neighboring key frames of a scan stored in memory based on the estimated position of the new image; comparing the new image to the identified key frames to determine a relative displacement of the new image from the neighboring key frames; and determining a position of the new image based on the relative displacement of the new image. The system includes: a microscope; a camera coupled to the microscope for capturing images through the microscope; and a computing device coupled to the camera, the computing device comprising: a memory; and a processor configured and adapted to perform a method as described herein.

Abstract: Method for detection of at least one reversibly photo-convertible fluorescent species (P), comprising the following steps: a) illumination of a sample comprising said or at least one of said reversibly photo-convertible fluorescent species by a periodically modulated illuminating light (FEX); and b) detection of fluorescent emission (FLU) emitted by the sample thus illuminated; characterized in that the method further comprises the following step: c) extraction of the amplitude (IFOUt) of the intensity component of said fluorescent emission exhibiting the same periodicity as said periodically modulated illuminating light and a phase quadrature with respect to the same; and in that the mean intensity of said illuminating light and the modulation frequency of the same are chosen in such a way as to maximise said amplitude of the intensity component of said fluorescent emission.

Abstract: Provided herein is an anesthesia station for at least one laboratory animal, including an anesthesia area connected to at least one peripheral receiving the laboratory animal. The anesthesia area is able to supply the peripheral with, halogenated anesthetic gases. The station further includes a system for aspirating the halogenated gases from the peripheral and at least one filter having a determined organohalogen concentration retention capacity. The filter is arranged in such a way as to be crossed by the halogenated anesthetic gases from the peripheral during operation of the aspiration system. The station also includes a system for the automatic determination in real-time of the organohalogen saturation rate of the filter.

Abstract: An absorbent sheet products strip, the strip including a continuous succession of individual absorbent sheets separated from each other by tear lines. The absorbent sheets are made of at least two plies bonded together by bonding points or lines or curves forming pattern units. Multiple pattern units are distributed all over a surface of the individual absorbent sheets such that the pattern units of one individual absorbent sheet does not superpose with other pattern units of a determined number of successive individual absorbent sheets in the strip when said successive individual absorbent sheets are disposed on each other.
