A novel generalized spatial mark‐resight model that accounts for group associations
Methods in Ecology and Evolution, EarlyView.Abstract The number and distribution of animals in space form the basis of many wildlife studies. Yet, reliable estimation of population abundance remains challenging. Generalized spatial mark‐resight (gSMR) models are widely applicable abundance estimators that do not require all individuals be uniquely identifiable.

Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 39-78, March 2025.Abstract This study collects original data to examine the determinants of classification criteria of county hierarchy and its rank variations during the Tang–Song period. The results reveal that the county hierarchy was affected by both economic and political situations, with more emphasis on politics in Tang and economics in Song.

Asia-Pacific Journal of Clinical Oncology, EarlyView.The study identified key barriers to optimal patient‐centered care, including delayed diagnosis due to awareness and stigma‐related barriers among patients and caregivers, and opportunities to enhance multidisciplinary coordination. Resource limitations impacted nursing and psychosocial support, while access to support care varied across regions.

Miners' Reward Elasticity and Stability of Competing Proof‐of‐Work Cryptocurrencies
International Economic Review, EarlyView.ABSTRACT Proof‐of‐Work cryptocurrencies employ miners to sustain the system through algorithmic reward adjustments. We develop a stochastic model of the multicurrency mining and identify conditions for stable transaction speeds. Bitcoin's algorithm requires hash supply elasticity <$<$1 for stability, while ASERT remains stable for any elasticity and ...

Instantiating Random Oracles via UCEs [PDF]
, 2013 This paper provides a (standard-model) notion of security for (keyed) hash functions, called UCE, that we show enables instantiation of random oracles (ROs) in a fairly broad and systematic way. Goals and schemes we consider include deterministic PKE; message-locked encryption; hardcore functions; point-function obfuscation; OAEP; encryption secure for

Permutation-Based Hash Chains with Application to Password Hashing
IACR Transactions on Symmetric CryptologyHash chain based password systems are a useful way to guarantee authentication with one-time passwords. The core idea dates back to Lamport, and is specified in RFC 1760 as S/Key. At CCS 2017, Kogan et al.
