We theoretically investigate the phase locking phenomena between the spectral components of Kerr optical frequency combs in the dynamical regime of Turing patterns. We show that these Turing patterns display a particularly strong and robust phase locking, originating from a cascade of phase locked triplets which asymptotically lead to a global phase locking between the modes. The local and glob...

The locking bandwidth of an actively mode-locked semiconductor laser is a measure of its tolerance to variations in the input drive frequency. At frequencies outside the locking bandwidth, the output pulses from the laser exhibit large amplitude fluctuations and timing jitter. This paper investigates the locking bandwidths of fundamentally driven and harmonically driven high-repetition-rate act...

In this paper we discuss locking and robustness of the nite element method for a model circular arch problem. It is shown that in the primal variable (i.e., the standard displacement formulation), the p-version is free from locking and uniformly robust with order p ?k and hence exhibits optimal rate of convergence. On the other hand, the h-version shows locking of order h ?2 , and is uniformly ...

Advanced multi-threaded programs apply concurrency concepts in sophisticated ways. For instance, they use fine-grained locking to increase parallelism and change locking orders dynamically when data structures are being reorganized. This paper presents a sound and modular verification methodology that can handle advanced concurrency patterns in multi-threaded, object-based programs. The methodo...

The repair of large distal femoral tumor defects can be challenging for orthopedic surgeons. The combination of a double-barrel free vascularized fibular graft (DFVFG) with a locking plate is a viable option. However, the biomechanical influence of the fibular bone length on the locking plate attachment is unclear. We aimed to evaluate the stability of the distal femoral defect after reconstruc...

Over the past several decades, much research has been done in the area of modeling, simulating, and measuring the performance of locking primitives under conditions of low and high contention and with attention to memory locality of the locking data structures. Most of the existing locking primitives are not fair with respect to lock grants and can cause lock starvation among CPUs during high c...

In real-time systems, cache memory poses challenge to improve both predictability and performance because of its adaptive and dynamic behavior. Recent studies indicate that for application-specific embedded systems, static cache-locking helps determining the worst case execution time (WCET) and cache-related preemption delay. In this work, we propose a static instruction cachelocking algorithm ...

By utilizing a racetrack resonator topography, an on-chip mode locked silicon evanescent laser (ML-SEL) is realized that is independent of facet polishing. This enables integration with other devices on silicon and precise control of the ML-SEL's repetition rate through lithographic definition of the cavity length. Both passive and hybrid mode-locking have been achieved with transform limited, ...

Phase-locking behaviors in sinoatrial node (SAN) are closely related to cardiac arrhythmias. An ionic model considering structural heterogeneity of SAN is numerically investigated. The bifurcations between phase-locking zones are interpreted by the map derived from the phase resetting curve. Furthermore, the validity of the circle map in describing phase locking of the actual SAN system is eval...
