ACM Transactions on Database Systems, 1994
Long-lived transactions (LLTs) hold on to database resources for relatively long periods of time, significantly delaying the completion of shorter and more common transactions. To alleviate this problem we propose an extension to two-phase locking, called altruistic locking, whereby LLTs can release their locks early.

Lock Detection in Phase-Locked Loops
SIAM Journal on Applied Mathematics, 1992The phase quadrature lock detector is used extensively to detect phase lock in phase-locked loops (PLLs). However, this lock detector's relationship to PLL closed-loop dynamics has never been established. A new theory is presented, which accomplishes this for a specified class of PLLs.

A lock-in amplifier measures a signal amplitude hidden in a noisy environment. An AC modulation is used to measure the signal in a very narrow frequency range. Using the lock-in technique the noise can be even much larger than the signal which can nevertheless be measured precisely.
