Not all Temperature Shocks are Alike: Disentangling Heat and High Temperature Shocks and Their Effects on Inflation in Australia

Economic Record, EarlyView.
We study the effects of heat and high temperature shocks on inflation in Australia using monthly, state‐level temperature anomaly data via two stages. In the first stage, we decompose temperature anomalies into orthogonal components using a structural vector autoregression with long‐run restrictions.

Permutation-Based Hash Chains with Application to Password Hashing

IACR Transactions on Symmetric Cryptology
Hash 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.

From politics to economics: The investigation of the determinants of local administrative hierarchy in the Tang–Song transition

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.

Double-sided: tight proofs for guessing games in the quantum random oracle model

Cybersecurity
The semi-classical One-Way to Hiding (SC-O2H) lemma given by Ambainis et al. (CRYPTO 2019) is a crucial technique to solve the reprogramming problem in the quantum random oracle model (QROM), which can lead to quadratically better bounds for many cases ...

Multi-User Security Bound for Mixed Filter Permutators in the Random Oracle Model

IACR Transactions on Symmetric Cryptology
At Eurocrypt’16, Méaux et al. designed a construction for symmetric ciphers that can be efficiently evaluated with Fully Homomorphic Encryption, dubbed Filter Permutator. They also specify FLIP, a family of Filter Permutators.

Voice of Asia: Provision of Patient‐Centered Care in Oral Cavity Cancer: A Qualitative Study With Patients, Caregivers, and Healthcare Professionals in Five Asia‐Pacific Regions

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.

Robo‐Saber: Generating and Simulating Virtual Reality Players

Computer Graphics Forum, EarlyView.
Abstract We present the first motion generation system for playtesting virtual reality (VR) games. Our player model generates VR headset and handheld controller movements from in‐game object arrangements, guided by style reference gameplay examples. We train on the large BOXRR‐23 dataset and apply our framework on the popular VR game Beat Saber.

OUGS: Active View Selection via Object‐aware Uncertainty Estimation in 3DGS

Computer Graphics Forum, EarlyView.
Abstract Recent advances in 3D Gaussian Splatting (3DGS) have achieved state‐of‐the‐art results for novel view synthesis. However, efficiently capturing high‐fidelity reconstructions of specific objects within complex scenes remains a significant challenge.

Unclonable Encryption in the Haar Random Oracle Model

CoRR
We construct unclonable encryption (UE) in the Haar random oracle model, where all parties have query access to $U,U^\dagger,U^*,U^T$ for a Haar random unitary $U$. Our scheme satisfies the standard notion of unclonable indistinguishability security, supports reuse of the secret key, and can encrypt arbitrary-length messages. That is, we give the first
