Our observations indicate that IO schedulers for ULL storage either do not help or significantly increase request latencies while also negatively impacting throughput and energy efficiency. Although we recognize the value of IO schedulers for slower devices or for other metrics such as fairness and QoS, we believe that IO schedulers have become …

This phenomenon is now called the Josephson effect. The SQUID consists of a superconducting current loop containing two Josephson junctions, as shown in Figure 9.7.3 9.7. 3. When the loop is placed in even a very weak magnetic field, there is an interference effect that depends on the strength of the magnetic field.
In order to demonstrate Superconductor Magnetic Energy Storage (SMES) is the classroom we can take a Quantum Levitator and induce currents in it. These currents persist as long as it remains cold. We can use a regular compass to verify their existence. Alternatively we can map these currents by measuring the local magnetic field …
Superconductivity: the search and the scandal. By Kit Chapman 15 April 2024. Recent high profile controversies haven''t deterred scientists from searching for one of research''s ultimate prizes: room temperature superconductors. Kit Chapman reports on the claims. In July 2023, the world became obsessed with superconductivity.

The superconductivity phenomenon was still quite mysterious as to its microscopic origin until 1957. In that year, the trio John Bardeen, Leon N. Cooper and John Robert Schrieffer of the United States developed the first fully quantum theory, BCS theory, which successfully explains the microscopic behavior of superconductivity in metals …
We might expect then that in these materials, the interaction is so weak that Cooper pairs cannot be formed, and superconductivity is therefore precluded.
