Datacollection in Event-Driven Wireless Sensor Networks with Mobile Sinks

International Journal of Distributed Sensor Networks, 2010
We present a two-tier distributed hash table-based scheme for data-collection in event-driven wireless sensor networks. The proposed method leverages mobile sinks to significantly extend the lifetime of the sensor network. We propose localized algorithms

Better GPU Hash Tables

, 2021
We revisit the problem of building static hash tables on the GPU and design and build three bucketed hash tables that use different probing schemes. Our implementations are lock-free and offer efficient memory access patterns; thus, only the probing scheme is the factor affecting the performance of the hash table's different operations.

The Measurement of Evidence‐Based Healthcare Competence of Nurses and Associated Background Factors: A Scoping Review

Research in Nursing &Health, EarlyView.
ABSTRACT Advancing evidence‐based practice requires nurses to have competence in the spectrum of evidence‐translation process known as evidence‐based healthcare. A scoping review was conducted to identify the instruments used to measure nurses evidence‐based healthcare competence and map the associated background factors.

Hash in a Flash: Hash Tables for Solid State Devices

, 2012
In recent years, information retrieval algorithms have taken center stage for extracting important data in ever larger datasets. Advances in hardware technology have lead to the increasingly wide spread use of flash storage devices. Such devices have clear benefits over traditional hard drives in terms of latency of access, bandwidth and random access ...

Integrating target capture with whole genome sequencing of recent and natural history collections to explain the phylogeography of wild‐growing and cultivated cannabis

PLANTS, PEOPLE, PLANET, EarlyView.
Cannabis has been used by humans for millennia, resulting in diverse landraces and uses. Its complex legal status and economic importance make sampling wild‐growing populations difficult, limiting past studies to modern cultivars with low genetic diversity. Our research provides crucial insights into the genetic diversity of wild‐growing and cultivated

Laser Synthesis in Liquid Induced Lattice Distortion in PtFeSn/Activated Carbon for Enhanced Methylcyclohexane Dehydrogenation

Small Methods, EarlyView.
A Pt‐Fe‐Sn alloy catalyst supported on activated carbon is synthesized via laser synthesis in liquid, introducing lattice distortions that enhance active site exposure and toluene desorption. The catalyst achieves a hydrogen evolution rate of 2625 mmol gPt⁻¹ min⁻¹ with 99.96% selectivity and excellent stability, offering a promising strategy for ...
