Also called magnetic core. Base The root or stem of a word or a derivative. Core The central portion of the earth below the mantle, beginning at a depth of about 2,900 kilometers (1,800 miles) and probably consisting of iron and nickel. It is made up of a liquid outer core and a...
BSS may also be produced by collision in the dense core of GCs. In that case, there should not be large chemical anomalies (Lombardi et al.1995). However, the majority of BSS in both globular and open clusters are likely the aftermath of the evolution of primordial binaries (see, e.g....
EF Core supports queries that include historical data through several new query operators:TemporalAsOf: Returns rows that were active (current) at the given UTC time. This is a single row from the current table or history table for a given primary key. TemporalAll: Returns all rows in the ...

Scaling quantum hardware: Although powerful, qubits are also quite error-prone, requiring large cooling systems capable of creating temperatures lower than outer space. Researchers are currently developing ways to scale qubits, electronics, infrastructure and software to reduce footprint, cost and energy...
IP header. The data packet is then forwarded based on the new IP header. When the data packet is received by another device, the device removes the outer IP header and tunnel header to obtain the original data packet. In this process, the overlay network is unaware of the underlay network...
A label stack contains an ordered set of labels.Figure 1-7shows a label stack. The label close to the Layer 2 header is called the stack top label or outer label. The label close to the Layer 3 header is called stack bottom label or inner label. Theoretically, the number of MPLS labe...
If the principal's primary key is generated by the database, then the value to set for the foreign key in the dependent is not known until the principal has been inserted. EF Core generates two roundtrips for this--one to insert the principal and get back the new primary key, and a ...
