Tradeoff Between Speed and Memory Requirements for Decoding of Prefix-Free Codes
AlgorithmsFor the decoding of prefix-free codes such as Huffman code, we present a tradeoff between the decoding speed and memory requirements that results in an adapted decoding algorithm.

Parallel Multi‐Operand Addition Using CPA‐Trees and Carry‐Select Adders
International Journal of Circuit Theory and Applications, EarlyView.A balanced parallel CPA‐tree architecture with CSLA reduces the critical‐path delay of multi‐operand addition while preserving structural regularity. ASIC results demonstrate delay reductions of up to 34% with low area overhead, providing an efficient and scalable solution for high‐performance arithmetic.

‘biomod2' – extending presence–absence species distribution models to multiple data types
Ecography, EarlyView.The R package ‘biomod2' is one of the most widely used and versatile tools for species distribution modelling (SDM), enabling ecologists to calibrate, evaluate, and project species–environment relationships across space and time using multiple modelling algorithms and ensemble forecasting.

The Unintended Consequences of Sugar‐Sweetened Beverage Taxes on Sales and Prices of Beer Beverages
Health Economics, EarlyView.ABSTRACT This paper estimates the causal effect of Berkeley's sugar‐sweetened beverage (SSB) tax on beer purchases and prices using retail scanner data from 2014 to 2015. Applying both synthetic control and difference‐in‐differences (DID) approaches, we find that the tax reduced beer purchases within Berkeley by 8.9%, while having a negligible effect ...

International Journal of Cancer, EarlyView.Patients with metastatic colorectal cancer who are ineligible for upfront metastasectomy may still become candidates for secondary metastasectomy with curative intent following response to primary chemotherapy. However, most studies dichotomize metastatic colorectal cancer into resectable and unresectable disease.

Other-Cell Interference Reducing Resource Allocation in OFDM-Based Asynchronous Cellular Systems
EURASIP Journal on Wireless Communications and Networking, 2007 Orthogonal frequency division multiplexing (OFDM) is considered as one of the most promising techniques for next-generation wireless access systems. However, it may suffer from the so-called other-cell interference (OCI) in cellular environments.

International Journal of Gynecology &Obstetrics, EarlyView.Abstract Background Prior cesarean delivery (CD) is a leading indication for repeat CD and a key driver of rising cesarean rates in Sub‐Saharan Africa. Evidence on associations between prior CD and adverse outcomes in low‐resource settings remains limited.
