A Case for Partitioned Bloom Filters [PDF]
, 2020 In a partitioned Bloom Filter the $m$ bit vector is split into $k$ disjoint $m/k$ sized parts, one per hash function. Contrary to hardware designs, where they prevail, software implementations mostly adopt standard Bloom filters, considering partitioned filters slightly worse, due to the slightly larger false positive rate (FPR).

Attacks on double block length hash functions [PDF]
, 1994 Attacks on double block length hash functions using a block cipher are considered in this paper. We present a general free-start attack, in which the attacker is free to choose the initial value, and a real attack on a large class of hash functions. Recent results on the complexities of attacks on double block hash functions are summarized.

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 ...

Trading Determinism for Time in Space Bounded Computations [PDF]
, 2016 Savitch showed in $1970$ that nondeterministic logspace (NL) is contained in deterministic $\mathcal{O}(\log^2 n)$ space but his algorithm requires quasipolynomial time.

Key Considerations on CITE‐Seq for Single‐Cell Multiomics
PROTEOMICS, EarlyView.ABSTRACT CITE‐Seq (Cellular Indexing of Transcriptomes and Epitopes by Sequencing) is an advanced single‐cell sequencing method to profile both gene expression and protein abundance simultaneously in individual cells using single‐cell mRNA sequencing techniques alongside antibody‐derived tags (ADTs), for protein detection.

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.

Leveraging Blockchain and Smart Contracts to Combat Greenwashing in Sustainable Development
Sustainable Development, EarlyView.ABSTRACT Blockchain technology, when combined with smart contracts, enables buyers to distinguish between greenwashed and genuinely eco‐friendly products. The presence of counterfeit items can severely impact supply chains by diminishing brand value, eroding consumer confidence, and undermining market trust.
