Abstract: The invention is a device for sampling fluids under pressure from a well which comprises a chamber for retaining the fluid within a sample chamber (01). The chambers includes a first piston which allows or prevents fluid inflow into the lower part of the chamber. The first piston is displaced by means comprising an elastic element (20) disposed in a chamber filled with oil and connected to the piston by a rod (04). Sampled fluid transfer means allows control of the descent of a second piston (02) from the upper part to the lower part of the chamber so that the fluid remains at constant pressure in chamber during the transfer.

Abstract: An information exchange platform referred to as a Trading Grid (TG) may perform relationship-based data processing utilizing a trading partner (TP) graph that describes relationships amongst operating units (OUs) on the TG. When the TG receives a request from an OU to exchange data with a TP, the TG accesses the TP graph and determines a relationship between the OU and their TP as reflected in the TP graph. The TP graph is maintained and controlled by the system independently of the OU and the TP. The TG may route the data based on instructions associated with the relationship that is reflected in the TP graph. The instructions associated with the relationship may specify network based services provided by the TG. An orchestration component may operate to orchestrate the performance of the network based services. The TG then communicates the processed and/or produced data to the TP.

Abstract: Examples methods, apparatus/systems and articles of manufacture for auditing point-of-sale images are disclosed herein. Example methods disclosed herein include comparing a region of interest of an image displayed via a user interface with a plurality of reference product images stored in a database to identify a plurality of candidate product images from the plurality of reference product images as potential matches to a first product depicted in the image. For example, the candidate product images are associated with respective confidence levels indicating respective likelihoods of matching the first product. Disclosed example methods also include displaying, via the user interface, the candidate product images simultaneously with the image in a manner based on the respective confidence levels, and automatically selecting a first one of the candidate product images as matching the first product based on the respective confidence levels.

Abstract: An extension to the enhanced serial generalized bit-flipping decoding algorithm (ES-GBFDA) of non-binary LDPC codes by introducing soft information in the check node operation. The application not only considers the most reliable symbol in the syndrome computation, but also takes at least the second most reliable symbol of each incoming message into account. An extended information set is available for the parity-check node update and this allows introducing the concept of weak and strong votes performed by the check node unit. Each variable node can receive two kinds of votes, whose amplitudes can be tuned to the reliability of the syndrome that produces the vote.

Abstract: The present invention is based on the surprising discovery that the overexpression of the SCL gene, of nucleotide sequence SEQ ID NO: 1, increases the production of megakaryocytes and platelets from stem cells. Likewise, it has been proven that this increase also occurs using PSCs which, unlike CD34+ HSC cells which have a limited expansion capacity, are characterized by an unlimited growth capacity, and can result in the unlimited production of platelets for the use thereof in clinics.
