This means that anyone can implement an XMPP service. More recently it has been standardized by the Internet Engineering Task Force (IETF), and it has become a popular choice for messaging apps. Today it is used by the likes of WhatsApp and Converse. A notable characteristic of XMPP is ...
As an event-driven technology, WebSocket allows data to be transferred without the client requesting it. This characteristic is desirable in scenarios where the client needs to react quickly to an event (especially ones it cannot predict, such as a fraud alert). WebSocket disadvantages WebSocket ...
The most common mistake associated with calling either getsockopt() or setsockopt() is attempting to obtain socket information for a socket whose underlying protocol doesn't possess that particular characteristic. For example, a socket of type SOCK_STREAM is not capable of broadcasting data;...

Mining the key genes involved in the balance of rice salt tolerance is extremely important for developing salt-tolerant rice varieties. A library of japonica mutants was screened under salinity conditions to identify putative salt stress-responsive genes. We identified a highly salt-sensitive mutant ss...
3. UDP-GlcNAc Participates in Many Forms of Glycosylation 3.1. UDP-GlcNAc Is Produced by the HBP and Can Be Converted into UDP-GalNAc and CMP-NeuAc UDP-GlcNAc is the end-product of the HBP (Figure 3), and is the second most abundant nucleotide-based structure in the cell after ATP. ...
