This paper presents a new and practical approach to lock-free locks based on helping, which allows the user to write code using fine-grained locks, but run it in a lock-free manner. Although lock-free locks have been suggested in the past, they are widely viewed as impractical, have some key limitations, and, as far as we know, have never been ...

Giant injection-locking bandwidth of a self-pulsing limit-cycle in an optomechanical cavity
Locking of oscillators to ultra-stable external sources is of paramount importance for improving close-to-carrier phase noise in free running oscillators.

Lock-Free Hopscotch Hashing [PDF]
In this paper we present a lock-free version of Hopscotch Hashing. Hopscotch Hashing is an open addressing algorithm originally proposed by Herlihy, Shavit, and Tzafrir, which is known for fast performance and excellent cache locality. The algorithm allows users of the table to skip or jump over irrelevant entries, allowing quick search, insertion, and

Optimality analysis of train platforming and routing with different interlocking modes
The train platforming and routing (TPR) problem is to decide train operations within stations after the network-wise train schedules are determined. A feasible TPR plan requires both platform and route conflict-free, where the avoidance of route conflict

Lock-free parallel dynamic programming [PDF]
We show a method for parallelizing top down dynamic programs in a straightforward way by a careful choice of a lock-free shared hash table implementation and randomization of the order in which the dynamic program computes its subproblems. This generic approach is applied to dynamic programs for knapsack, shortest paths, and RNA structure alignment, as

Mechanisms of dual-wavelength dissipative soliton mode-locking in net-normal dispersion fiber lasers
Dual-wavelength mode-locked fiber lasers have attracted great attention due to their enormous potential in facilitating dual-comb spectroscopy. However, mechanism for dual-wavelength dissipative soliton mode-locking and the intracavity dynamics are still

On-Demand Q-Switching Regime in Optically Injected Dual-Section Quantum-Dot Laser
Pure Q-switching (self-pulsating) behaviour is shown for the first time in an optically injected two-section quantum-dot laser. Upon CW optical injection, it was possible to switch the operation regime from free-running mode-locking to locked Q-switching.

Injection locking and noise reduction of resonant tunneling diode terahertz oscillator
We studied the injection-locking properties of a resonant-tunneling-diode terahertz oscillator in the small-signal injection regime with a frequency-stabilized continuous THz wave.

2:1 Injection-Locked Frequency Dividers Using Multi-Resonance Spiral-Inductor Resonator
This article describes two low-power and wide locking range capacitive cross-coupled divideby-2 injection-locked frequency dividers (ILFDs) implemented in TSMC standard 0.18 μm processes.

Background Restoration with locking-taper implants is a widely used methodology. However, conical connection systems such as locking-taper implant systems have rarely been examined. This study provides a retrospective investigation of locking-taper fixed
