The management of nutrients presents a significant challenge for farmers and is a matter of concern for environmentalists. The key issue doesn’t lie in innovation but in the diffusion of technology among agricultural practitioners. Developed by international fertilizer development corporations, Urea Deep Placement (UDP) technology represents an innovative approach to rice cultivation. Its primary objective is to address the issue of nitrogen loss and enhance the utilization efficiency of urea.

An optimized coupled enzyme assay for UDP‐glucose pyrophosphorylase (EC 2.7.7.9) using UDP‐glucose dehydrogenase (EC 1.1.1.22) is presented.

In addition the data provide a basis for the enzymatic synthesis of UDP‐glucuronic acid. The results demonstrate that the two binding sites of the dehydrogenase differ since a different modulation of the enzyme activity and stability is observed after preincubation with UDP‐glucose or NAD+ at various pH values.

Abstract:
With the development of aerospace technology, the flight control system is getting more and more important for a UAV (Unmanned Aerial Vehicle) flying safely and efficiently. For collecting the experimental data without delay, this paper briefly reviews the design of the communication scheme, and provides the implemented results. Through using the controller LPC1768 to expand the serial port, and the Ethernet controller DP83848 to complete the communication by UDP protocol, it turns out that this method is able to reach the real-time requirements of the UAV semi-physical simulation.

Abstract:
Vehicle pose detection plays a vital role in modern automotive technology, which can improve driving safety, enhance vehicle stability and provide important support for the development of autonomous driving technology. The current pose estimation methods have the problems of accumulation errors, large algorithm computing power, and expensive cost, so they cannot be widely used in intelligent connected vehicles. This paper proposes a vehicle pose detection method based on an RSU (Roadside Unit). First, the on-board GPS performs the positioning of the target vehicle and transmits the positioning

Abstract:
The implementation of highly sensitive and rapid mass spectrometric screening strategies for defining the glycosylation repertoires of organs in knockout mice is helping to reveal the roles that glycans play in health and disease. Thus novel glycosylation pathways have been uncovered in two such knockouts, namely α-mannosidase II null mice and UDP-N-acetylglucosamine:α6-d-mannosideϐ1,2-N-acetylglucosaminyltransferase II null mice. This chapter documents the glycosylation profiles of a wide range of organs from the normal mouse which should facilitate future glycomics studies of knockout mice.

As network technology continues to advance, network congestion has become an inevitable aspect of network communication. Considering the external interference, unmodeled uncertainty and the interaction between nodes, a multi-bottleneck TCP/AWM network model is established in this paper. A new fixed-time congestion controller was designed by combining a neural network and the backstepping technique. The neural network approximation property is used to eliminate the interference of unmodeled uncertainty and UDP flow in the system. The controller designed in this paper can ensure the stability of
