Mobile device transactions have become commonplace today.Quick-response (QR) codes and near-field communication (NFC) are popular cashless and contactless payment methods.These two payments have their characteristics.NFC payments use secure elements that encrypt credential data to ensure safe transactions.In contrast, QR code payments transmit data
To give full play to the advantages of pure electric drive, and aimed at the transmission system of electric loader, the low efficiency hydraulic torque converter and reverse direction clutch of traditional models are cancelled.By analyzing the shift law of the pure electric drive system, the Wrap electro-hydraulic shift control system is used to c
Although studies have revealed the significant impact of dietary fiber on growth performance and nutrient digestibility, the specific characteristics of the intestinal microbiota and gene regulation in pigs capable of digesting high-fiber diets remained unclear.To investigate the traits associated with roughage tolerance in the Chinese indigenous p
Abstract High-dimensional linear regression model is the Wrap most popular statistical model for high-dimensional data, but it is quite a challenging task to achieve a sparse set of regression coefficients.In this paper, we propose a simple heuristic algorithm to construct sparse high-dimensional linear regression models, which is adapted from the
