RDHNet: Reversible Data Hiding Method for Securing Colour Images Using AlexNet and Watershed Transform in a Fusion Domain

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Medical images play a crucial role in diagnosis, treatment procedures and overall healthcare. Nevertheless, they also pose substantial risks to patient confidentiality and safety. Safeguarding the confidentiality of patients' data has become an urgent and practical concern.

Machine Learning Enables Alignment‐Free Distance Calculation and Phylogenetic Placement Using k‐Mer Frequencies

Molecular Ecology Resources, EarlyView.
ABSTRACT A key application of phylogenetics in ecological studies is identifying unknown sequences with respect to known ones. This goal can be formalised as assigning taxonomic labels or inserting sequences into a reference phylogenetic tree (phylogenetic placement). Much attention has been paid to the phylogenetic placement of short fragments used in

Cache-Oblivious Peeling of Random Hypergraphs

, 2013
The computation of a peeling order in a randomly generated hypergraph is the most time-consuming step in a number of constructions, such as perfect hashing schemes, random $r$-SAT solvers, error-correcting codes, and approximate set encodings.

Blockchain technology disruptions: Exploring accounting and auditing academics and practitioners' perception

Accounting &Finance, EarlyView.
Abstract This study explores the practical impact of blockchain technology (BCT), which contrasts strongly with literature that has predominantly hypothesised BCT's potential to disrupt accounting practice. We interviewed 44 practitioners and academics with knowledge of BCT across 13 countries and industries.

The Usefulness of Multilevel Hash Tables with Multiple Hash Functions in Large Databases [PDF]

, 2009
In this work, attempt is made to select three good hash functions which uniformly distribute hash values that permute their internal states and allow the input bits to generate different output bits.

Development, external validation and integration into clinical workflow of machine learning models to support pre‐operative assessment in the UK

Anaesthesia, EarlyView.
Summary Introduction Demand for surgical treatment is growing and patient complexity is increasing. The NHS England standard contract now requires that pre‐operative services risk stratify and optimise patients awaiting surgery. However, current pre‐operative workflows (whether electronic or paper‐based) remain based primarily on resource‐intensive ...

Implicit Promises and the Timing of Defined‐Benefit Pension Plan Freezes

Financial Management, EarlyView.
ABSTRACT Firms time defined‐benefit (DB) plan freezes after CEO turnovers to protect CEO retirement benefits from cost cuts affecting the wider workforce. We document a significant increase in voluntary CEO turnovers just before the freeze, without notable post‐freeze changes.

Finding succinct ordered minimal perfect hashing functions [PDF]

, 1992
An ordered minimal perfect hash table is one in which no collisions occur among a predefined set of keys, no space is unused, and the data are placed in the table in order. A new method for creating ordered minimal perfect hashing functions is presented.
