Exploiting the lock: leveraging MiG-V's logic locking for secret-data extraction.

The MiG-V was designed for high-security applications and is the first commercially available logic-locked RISC-V processor on the market. In this context, logic locking was used to protect the RISC-V processor design during the untrusted manufacturing process by using key-driven logic gates to obfuscate the original design. Although this method defends against malicious modifications, such as hardware Trojans, logic locking's impact on the RISC-V processor's data confidentiality during runtime has not been thoroughly examined.

NMR studies of phenylbenzohydroxamic acid and kinetics of complex formation with nickel(II).

The behavior of N-phenylbenzohydroxamic acid (PBHA) in organic solvents has been investigated by (1)H and (13)C NMR spectroscopy. Measurements in acetone at different temperatures and concentrations enable one to individualized two signals, in a 20/80 area ratio, which were ascribed to partition of PBHA between two isomers, HZ (cis) and HE (trans). The dependence of the low-intensity peak on concentration and temperature strongly suggests dimer formation.
