A family of carboxylic acid group containing fluorene / fluorenon copolymers is disclosed as binders of silicon particles in the fabrication of negative electrodes for use with lithium ion batteries. These binders enable the use of silicon as an electrode material as they significantly improve the cycle-ability of silicon by preventing electrode degradation over time. In particular, these polymers, which become conductive on first charge, bind to the silicon particles of the electrode, are flexible so as to better accommodate the expansion and contraction of the electrode during charge / discharge, and being conductive promote the flow battery current.

A golf swing formation aid has a resilient cushion sandwiched between two additional resilient cushions, with sleeves to receive the arms of a golfer holding a golf club to provide between the arms a predetermined spacing during a swing of the golf club by the golfer. A differential in the resilience of the cushions allows for accommodation of the movement of the arms during the swing while maintaining the predetermined spacing. The cushions have different degrees of resilience.

The invention relates to a preparation method for a man-made lawn. The preparation method comprises the following steps: arranging warp yarns on a warp beam of a braiding machine, arranging weft yarns on the braiding machine in a direction perpendicular to the warp yarns, arranging man-made grass silk yarns on a yarn creel at the back part of the braiding machine, enabling the man-made grass silk yarns to participate in braiding of bottom cloth in a direction parallel to the warp yarns, and performing grass jacquard weaving treatment on the man-made grass silk yarns by utilizing jacquard equipment of the braiding machine; bypassing the bottom cloth for 2-10 circles by each man-made grass silk yarn to form a cluster of grass silk, setting the height of the grass silk cluster to be 10-70mm, and arranging 6-12 warp yarns between any two adjacent grass silk clusters; and arranging 3-8 weft yarns between any two adjacent grass silk clusters in the grass silk clusters arranged vertically. The preparation method is simple, easy to operate and convenient for industrial production, and pullout force of the grass silk can be increased; and the man-made lawn prepared with the method has the advantages of environmental protection, wide application range and high stability.

The invention relates to a steel bone concrete column, and particularly relates to an H-shaped steel bone-confined concrete column with round steel draw bars. The H-shaped steel bone-confined concrete column with the round steel draw bars comprises an H-shaped steel bone, the round steel draw bars, longitudinal reinforcement, a composite stirrup and concrete, wherein the round steel draw bars are connected with two flanges, at the outer sides of the flanges and near the free edges, of the H-shaped steel bone through bolts, so that the free extension length of each flange is effectively reduced, buckling deformation of the flanges is constrained, and meanwhile, the inspection capability of internal concrete of the steel bone is enhanced by existence of the round steel draw bars. The round steel draw bars are arranged at intervals, and the internal part of the steel bone is communicated with external concrete in series, so that the pouring quality of the concrete is ensured. Therefore, the concrete disclosed by the invention has the relatively high strength and the good elastic-plastic deformation capacity, and the formed steel bone concrete column has the relatively high bearing capacity, ductility and energy-dissipating capacity.

The invention discloses a training method of a deep convolutional neural network for face recognition. The method comprises the following steps: 1) preparing a face image data set, dividing the face image data set into a training set and a verification set, and selecting the type, the structure, the hyper-parameter and the magnitude of a deep convolutional neural network model according to the scale and the complexity of the training set and the performance index of face recognition which should be achieved; 2) extracting features of face pictures input by the training set by using the model,and taking the features as input in the step 3); 3) constructing a loss layer, and iteratively calculating a loss value for the training; 4) comparing the loss value calculated in the step 3) with a preset threshold value, judging whether training is stopped or the gradient is calculated, and updating model parameters; and 5) verifying the model performance, and determining whether to stop training. According to the method, the human face features can be constrained by using a multivariate acting force from two aspects of an Euclidean space and an angle space during training, so that the deepconvolutional neural network model can learn the human face features with higher discrimination and robustness.

Improved sucker rod joints for down hole petroleum pumping applications are provided within the form factor of standard API sucker rods, such that existing inventory in suitable condition is fully usable in more demanding applications. The pin ends are selected or processed such as to provide preselected axial distance between a flat pin end and at least one reference surface, such as a threaded region or reference shoulder or both. The coupler is dimensioned such that the pin ends are in abutment either with each other or with opposite sides of an intervening torque washer in the central region, when the connection is made to a selected level of thread engagement. Furthermore, the engagement is such as to put the pin ends in compression and the coextensive length of coupler in tension. This increases frictional restraints and locks the elements together to resist fatigue failure upon cycling and to insure together with an anaerobic adhesive sealant, against back threading. This arrangement enables standard quality sucker rods to be employed in a configuration which is mechanically secure and highly resistant to tensile, bending and torsional forces, thus assuring a greater strength at the joint than in the rod itself, and resisting the effects of material fatigue arising from long term and stressful cycling operations.
