Shared storage file systems consist of multiple storage devices connected by dedicated data-only network and workstations that can directly access the storage devices. In this shared-storage environment, data consistency is maintained by lock servers which use separate control network to transfer the lock information. Furthermore, lease mechanism is applied to cope with control network failures...

We investigated the noise levels in cell-attached patch capacitance recordings with a lock-in amplifier. The capacitance noise level decreases with increasing sine wave frequency up to 20-40 kHz. With a 20-mV rms sine wave the rms noise level above 8 kHz is <50 aF. With increasing sine wave amplitudes a further reduction down to 14 aF could be achieved. Capacitance measurements with a lock-in a...

This study examines the attitude of teachers toward e-learning as new learning modality and possible development general anxiety disorder among amidst COVID-19 pandemic. A sample 116 were taken before start school year another 75 after one semester executing served this study. Data collected through a self-administered survey questionnaire sent google form to comply with existing lockdown polic...

A race condition is a situation where two threads manipulate a data structure simultaneously, without synchronization. Race conditions are common errors in multithreaded programming. They often lead to unintended nondeterminism and wrong results. Moreover, they are notoriously hard to diagnose, and attempts to eliminate them can introduce deadlocks. In practice, race conditions and deadlocks ar...

Time-dependent coupled mode theory is used to investigate the stability of phase-locked semiconductor laser arrays. The output of individual array elements is dynamically unstable and exhibits large amplitude chaotic pulsations. The total output initially exhibits damped relaxation oscillations and then settles down. to a quasi-steady state characterized by small amplitude fluctuations. The the...
