Exact Methods for the Split Delivery Vehicle Routing Problem With Two‐Dimensional Loading Constraints

Networks, EarlyView.
ABSTRACT The Split Delivery Vehicle Routing Problem with Two‐dimensional Loading Constraints (2L‐SDVRP) integrates vehicle routing, split delivery, and two‐dimensional packing constraints. In the 2L‐SDVRP, customers can be served by multiple vehicles, and their demands consist of different two‐dimensional rectangular items that must be packed in the ...

Fast Structural Alignment of Biomolecules Using a Hash Table, N-Grams and String Descriptors

Algorithms, 2009
This work presents a generalized approach for the fast structural alignment of thousands of macromolecular structures. The method uses string representations of a macromolecular structure and a hash table that stores n-grams of a certain size for ...

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.

Fast Locality-Sensitive Hashing Frameworks for Approximate Near Neighbor Search

, 2018
The Indyk-Motwani Locality-Sensitive Hashing (LSH) framework (STOC 1998) is a general technique for constructing a data structure to answer approximate near neighbor queries by using a distribution $\mathcal{H}$ over locality-sensitive hash functions ...

SiO2@Benzothiazole‐Cl@Fc as an Efficient Heterogeneous Catalyst for the Synthesis of 1,3,5‐Trisubstituted Pyrazoles by A3 Coupling

ChemistryOpen, EarlyView.
This research introduces the preparation and analysis of a newly heterogeneous catalyst developed silica nanospheres supporting a ferrocene‐containing ionic liquid (SiO2@Benzothiazole‐Cl@Fc) for the A3 coupling reaction. The catalyst facilitates the efficient synthesis of 1,3,5‐trisubstituted pyrazoles from aromatic hydrazides, aldehydes, and aromatic ...

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

Arbuscular mycorrhizal fungi increase aleurone layer zinc concentration but reduce overall zinc bioavailability in rice grain

PLANTS, PEOPLE, PLANET, EarlyView.
Rice is a critical crop for the delivery of calories and essential micronutrients to the human diet. Biofortification of rice with zinc (Zn) and iron (Fe) aims to combat the health issues associated with “hidden hunger”. Arbuscular mycorrhizal (AM) fungi have been explored for their potential to enhance Zn and Fe uptake in rice products.

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 ...
