Distributed Quantum Machine Learning

Quantum computers can solve specific complex tasks for which no reasonable-time classical algorithm is known. Quantum computers do however also offer inherent security of data, as measurements destroy quantum states. Using shared entangled states, multiple parties can collaborate and securely compute quantum algorithms. In this paper we propose...

Vector Commitments over Rings and Compressed Σ -Protocols

Compressed Sigma -Protocol Theory (CRYPTO 2020) presents an “alternative” to Bulletproofs that achieves the same communication complexity while adhering more elegantly to existing Sigma -protocol theory, which enables their techniques to be directly applicable to other widely used settings in the context of “plug & play” algorithmics....

Using statistical and interval-based approaches to propagate snow measurement uncertainty to structural reliability

Observations are inevitably contaminated with measurement uncertainty, which is a predominant source of uncertainty in some cases. In present practice probabilistic models are typically fitted to measurements without proper consideration of this uncertainty. Hence, this study explores the effect of this simplification on structural reliability...

Retention of intermediate polarization states in ferroelectric materials enabling memories for multi-bit data storage

A homogeneous ferroelectric single crystal exhibits only two remanent polarization states that are stable over time, whereas intermediate, or unsaturated, polarization states are thermodynamically instable. Commonly used ferroelectric materials however, are inhomogeneous polycrystalline thin films or ceramics. To investigate the stability of...

Occupational exposure during application and removal of antifouling paints

Exposure data on biocides are relatively rare in published literature, especially for secondary exposure. This is also the case for antifouling exposure. Therefore, a field study was carried out measuring exposure to antifouling paints. Both primary exposure (rolling and spraying) and secondary exposure (during sand blasting) were studied....

School-age outcomes in children who were extremely low birth weight from four international population-based cohorts

Objective. The aim of this study was to determine whether leaming and school problems in extremely low birth weight (ELBW) and reference children differ between cohorts in different countries. Methods. Participants were 4 international population-based cohorts of ELBW survivors who were 500 to 1000 g birth weight from New Jersey, central-west...
