Abstract: An efficient tool to remove amplifier glow from low-light and long-exposure digital images, without sacrificing the useful signal contained in these images. This is particularly useful in deep space imagery, where long exposure times are common, and wherein the darkness of the capture images further highlights the effects of amplifier glow.

Abstract: A method for in-situ joint nanoscale three-dimensional imaging and chemical analysis of a sample. A single charged particle beam device is used for generating a sequence of two-dimensional nanoscale images of the sample, and for sputtering secondary ions from the sample. which are analysed using a secondary ion mass spectrometry device. The two-dimensional images are combined into a three-dimensional volume representation of the sample, the data of which is combined with the results of the chemical analysis.

Abstract: The invention relates to a three-dimensional in vitro alveolar lung model comprising essentially the four cells types as follows: alveolar type II epithelial cells able to secrete (lung laying) surfactant, endothelial cells which forms the inner lining of capillaries providing a permeable barrier, dendritic-like cells, such as non-differentiated THP-1, linking innate and adaptive immunity and macrophage-like cells, able to participate to defense mechanisms by ingesting foreign materials by phagocytosis.
The invention also relates to a process for preparing said model, and its use for assessing the irritation potential or toxicity of inhalable products such as particles or molecules on the alveolar barrier of lungs, and also for determining and/or predicting the sensitizing effects of inhalable products such as particles or molecules on the alveolar barrier of lungs.

Abstract: An aspect of the present invention pertains to a method for determining the volumetric flow rate of a compressible fluid flow flowing through a volume flowmeter having a flow inlet, a wheel downstream of the flow inlet and a constriction downstream of the flow inlet and upstream of the wheel, the compressible fluid flowing through the flow inlet and actuating the wheel. The method comprises measuring the rotational speed of the wheel and determining the permanent pressure loss across the wheel based on the measured rotational speed. The method further comprises measuring the fluid pressure of the compressible fluid flow at the flow inlet and determining whether the compressible fluid flow in the volume flowmeter is in the subsonic or in the supersonic regime based on the determined permanent pressure loss and the measured fluid pressure. The method also comprises measuring the fluid temperature of the compressible fluid flow at the flow inlet and determining the volumetric flow rate of the compressible fluid flow based on the determined permanent pressure loss, the measured fluid pressure, the regime of the compressible fluid flow and the measured fluid temperature. Other aspects of the present invention pertain to volume flowmeter for determining the volumetric flow rate of a compressible fluid flow, a data processing device for controlling a volume flowmeter, a computer program for the controller and a computer-readable medium having stored thereon the computer program.

Abstract: The present invention provides a method for mapping the wireless network environment as observed from a computing device having at least one network interface for accessing said environment. The mapping method requires limited storage space and processing power, so that it may be executed on said computing devices without requiring further network services. Structured mapped data generated from gathered network discovery traces enables a plurality of location-based, mobility or network routing services.

Abstract: A method for manufacturing a negatively charged supported lipid bilayer. The method comprises the steps of preparing a formulation comprising at least three lipids (1,2-dioleoyl-sn-glycero-3-phospho-L-serine (DOPS), cholesterol and at least one lipid different from DOPS and cholesterol) dissolved in a first solvent, of evaporating the first solvent, of adding an aqueous formulation of mesoporous silica nanoparticles, of performing an ultra-sonication and of performing a centrifugation. The method is remarkable in that the number of equivalents of cholesterol relative to one equivalent of DOPS is comprised between 2.30 and 2.70. Additionally, negatively charged supported lipid bilayer on a mesoporous silica nanoparticle comprising cholesterol, 1,2-dioleoyl-sn-glycero-3-phospho-L-serine (DOPS) and at least one lipid different from DOPS and cholesterol.

Abstract: The invention provides a method that allows to counter tracking mechanisms to which user terminals are exposed when they communicate data on the Internet. This is achieved by a proxy 5 system, which conceals the activity of user terminals from such tracking mechanisms. At the same time, the proxy system builds an enriched and detailed activity and user profile, to which third parties may be granted conditional access.

Abstract: A fluidized bed reactor designed for in situ gas phase impregnation. The reactor comprises a tube with an upstream zone and a downstream zone, the upstream zone and the downstream zone being separated by a separation filter. A method for a controlled-deposition of a sublimated precursor onto a fluidized solid support. The method is remarkable in that it is carried out in situ within the tube of the fluidized bed reactor in accordance with the fluidized bed reactor.

Abstract: The present invention provides a method for determining the relative proximity of wireless network devices. The method may advantageously be executed locally on a computing device, so that it provides enhanced reliability, responsiveness, security and privacy as compared to known methods requiring Internet access and/or satellite positioning signals. The determination of the proximity of networked devices allows for efficient implementation of several social network services, such as shared mobility services or location-based services, wherein the proximity of users/devices is a key 10 incentive for the service's usage.
