Abstract: A method for detecting a QRS complex of an electrocardiogram signal, an apparatus therefor, a device and a medium are provided. A QRS complex of an electrocardiogram signal is detected by a detection model including a DenseNet and a dual-channel Long Short-Term Memory (LSTM). Spatial feature information of the QRS complex in the electrocardiogram signal is learned through the DenseNet, and then the spatial feature learned by the DenseNet and the time sequence data are input into respective channels of the dual-channel LSTM, so that the dual-channel LSTM can fuse the spatial information and the time sequence information of the QRS complex in the electrocardiogram signal, thereby improving a segmentation effect of the model on features, and finally improving accuracy of detecting the QRS complex.

Abstract: A BIOS backup/recovery system includes a chassis housing a BIOS backup/recovery subsystem coupled to a primary and a secondary BIOS storage system. The BIOS backup/recovery subsystem begins initialization operations and determines whether the primary BIOS storage system includes customized MAC addresses. If so, the BIOS backup/recovery subsystem determines whether MAC addresses in the secondary BIOS storage system match the customized MAC addresses in the primary BIOS storage system and, if not, performs a BIOS backup operation that includes copying the customized MAC addresses in the primary BIOS storage system to the secondary BIOS storage system. If not, the BIOS backup/recovery subsystem determines whether MAC addresses in the secondary BIOS storage system match default MAC addresses in the primary BIOS storage system and, if not, performs a BIOS recovery operation that includes copying customized MAC addresses in the secondary BIOS storage system to the primary BIOS storage system.

Abstract: The present invention relates to an in vitro immune synapse system and a method of in vitro evaluating immune response using the same. The in vitro immune synapse system includes antigen-presenting cells (APCs) and at least one cell type of several specific T cell subtypes isolated from peripheral blood mononuclear cells (PBMCs), all of which is from a same individual of pigs. When a test sample is co-cultured in the in vitro immune synapse system for a given period, it can be determined that the test sample is immunogenic, immunostimulatory or not according to the immunization-related changes of these cells, thereby potentially replacing some kinds of animal experimentation.

Abstract: An assembly table includes a table plate, a table leg unit, a first connecting unit, a first mounting unit and a fastening unit. The table leg unit includes a first leg, a second leg and a third leg that are inclined with respect to the table plate, that intersect one another, and that are detachably mounted to a bottom surface of the table plate. The first connecting unit is detachably connected between the first leg and the second leg. The first mounting unit is detachably connected between the first leg and the third leg. The fastening unit includes a through hole formed through the third leg, and a penetrating fastener removably inserted through the through hole to fix the third leg to the second leg.

Abstract: A network communication method used in a network communication apparatus is provided that includes the steps outlined below. An external network communication apparatus is electrically coupled through a communication path. A communication capability packet is transmitted to the external network communication apparatus. Whether an acknowledgement packet from the external network communication apparatus is received through the communication path is determined. When the acknowledgement packet is not received, a single direction communication is performed within any single time period by using a time division communication mechanism such that an auto negotiation process is performed by exchanging the communication capability packet and the acknowledgement packet of both of the network communication apparatus and the external network communication apparatus.

Abstract: A 3D printing technology-based processing apparatus and method includes a frame, an injection unit, and a molding unit. A melted polymer filler can be filled into a blind hole or a passageway of a 3D printed product to improve overall strength of the product. A 3D printed product having a mortise and tenon shaped mechanical engagement structure is disclosed. The printed product having the mortise and tenon shaped structure has higher tensile strength and shear strength. The present apparatus effectively resolves a problem of warped and deformed products due to an excessive temperature difference between the product and an environment during printing. The method uses an optimized printing process to reduce the fabrication processes of a support structure, reduce consumables required for building the structure, and improve the printed surface quality of the printed product.

Abstract: A device and a method for analyzing an analyte in a liquid sample are provided. The device comprises a detecting chamber included in a detection device for containing a detecting element; a liquid sample transferring chamber; and a film with small pores disposed between the detecting chamber and liquid sample transferring chamber. When the detection device is inserted into a liquid sample collecting chamber, the liquid sample in the collecting chamber enters the liquid sample transferring chamber but cannot enter the detecting chamber via the film with small pores. When a piston is inserted into the liquid sample transferring chamber, the piston forces a part of liquid sample in the liquid sample transferring chamber to enter the detecting chamber via the film with small pores. Using the device and the method can determine an analyte in a sample quantitatively and can complete the detection in one step.
