Dissolved oxygen (DO) in the culture water is an important environmental factor in fish farming. This study tested whether genetically improved farmed tilapia (GIFT, Oreochromis niloticus) challenged with a hypoxic episode would show inhibited growth, increased metabolic stress and a reduced immune response. GIFT subjected to 72 hr of semi‐lethal hypoxia (determined by linear regression as DO = 0...
In most of the existing compressed sensing based Massive MIMO channel state information acquisition schemes, the huge overhead introduced by reconstruction and measurement of channel cannot afford by power-limited users. Combining channel estimation and feedback together, a Two-dimensional compressed sensing schemes is proposed for Massive MIMO channel state information. Instead of reconstruct the...
With the gradual formation of China's socialist market economic system, research on the government procurement market under an open economy will become an inevitable choice. Under the backdrop of the country's accession to WTO, the impact of Government Procurement Agreement (GPA) on the economy is increasingly evident, and China's accession to the agreement is not only the government's commitment,...
On December 28, 2007, China formally started accession negotiations on GPA, and the work is more urgent. To join the GPA, it not only means Chinese enterprises have entered the international government procurement markets, but also takes certain risks to the Chinese government and enterprises. This paper analyzes the current situation of China's government procurement, explores the domestic risks...
In this article, from the beginning, we interpreted the concept of the talented people. And then, we further analyzed the important role which the textile talents played in the development of the textile industry. Then we discussed the factors that affected the demand for textile talents, and built the prediction model. This model was used to predict the demand quantity and structure for textile talents.
In high-speed transmission circuits, signal integrity is an inevitable problem, a major factor caused PCB board signal integrity problems is impedance mismatch. This paper based on the theory of transmission lines, according to the coplanar waveguide (CPW) structure, designed a high-speed differential connector which was separated by air. And use 2D simulation software to analyse the differential...
In high-speed transmission circuits, signal integrity is an inevitable problem. This paper describes the air-isolated PCB connector design used in the aerospace electronic equipment. First based on the small size and light weight of aerospace electronic equipment and the combination of high-speed connector design method we proposed the concept of air-isolated. We study the factor impacting the high-speed...
A logistics cost model based on demand forecasting is proposed for a two-echelon distribution system with a central warehouse and multiple retailers in this paper. The retailers and the central warehouse all use periodic control policy to review their inventory level. First, we attempt to develop a fuzzy system-forecasting model capable of learning the IF-THEN rules obtained from demand data and experience...
