Quantum Error Correction on Superconducting Processors: A Short Communication
We benchmark surface code and repetition code implementations on 5 commercial superconducting quantum processors. Logical error rates per cycle range…
Observation of Non-Hermitian Skin Effect in Acoustic Metamaterials
We experimentally realize the non-Hermitian skin effect in a 1D acoustic metamaterial with engineered gain and loss. The bulk-boundary correspondence…
Topological Superconductivity in Hybrid Semiconductor-Superconductor Nanowires
We report experimental evidence of topological superconductivity in InAs/Al hybrid nanowires with epitaxial interfaces. Tunneling conductance spectroscopy reveals zero-bias peaks…

An evaluation of Welsh-medium digital immersion programs targeting adult heritage speakers (N=1,200) over three years. Participants showed statistically significant gains…
L2 Acquisition of Tonal Contrasts: A Longitudinal Study of Mandarin Learners
A two-year longitudinal study of 68 English-speaking learners of Mandarin tracks tonal accuracy development using acoustic measurements and perceptual judgments.…
Code-Switching Patterns in Multilingual Social Media: A Corpus Study
We analyze a 4.2-million-token corpus of multilingual Twitter data to characterize intra-sentential code-switching across English-Spanish, English-Arabic, and English-Mandarin pairs. Matrix…
Monetary Policy Transmission in Post-Pandemic Economies: Evidence from 40 Countries
This review synthesizes empirical evidence on monetary policy transmission across 40 economies from 2020 to 2024, characterized by historically high…
Trade War Spillovers: The Effect of US-China Tariffs on ASEAN Export Patterns
Difference-in-differences analysis of HS6-digit trade flows shows that US-China tariff escalation from 2018-2020 generated significant trade diversion to ASEAN economies.…
Digital Currency Adoption and Financial Inclusion in Sub-Saharan Africa
Using household survey data from 14 Sub-Saharan African countries (N=87,420), we examine determinants of mobile money and CBDC adoption. Instrumental…
