Cross-chain payment protocols with success guarantees

In this paper, we consider the problem of cross-chain payment whereby customers of different escrows-implemented by a bank or a blockchain smart contract-successfully transfer digital assets without trusting each other. Prior to this work, cross-chain paym ...

Cavity-assisted preparation and detection of a unitary Fermi gas

Jean-Philippe Brantut, Victor Youri Helson, Kevin Etienne Robert Roux, Hideki Konishi

We report on the fast production and weakly destructive detection of a Fermi gas with tunable interactions in a high finesse cavity. The cavity is used both with far off-resonant light to create a deep optical dipole trap, and with near-resonant light to r ...

Simulation of Instability in Time-Sensitive Networks with Regulators and Imperfect Clocks

Guillermo Aguirre Rodrigo

Regulators are used in time-sensitive networks in order to reshape traffic reducing the burstiness generated by the aggregation systems within the network. Regulators, in terms of the IEEE TSN group are defined as Asynchronous Traffic Shaping or what in th ...

The design of Wren, a Fast and Scalable Transactional Causally Consistent Geo-Replicated Key-Value Store

Willy Zwaenepoel, Diego Didona, Kristina Spirovska

This paper presents the design of Wren, a new geo-replicated key-value store that achieves Transactional Causal Consistency. Wren leverages two design choices to achieve higher performance and better scalability than existing systems. First, Wren uses hybr ...

8.4 A 2.5ps 0.8-to-3.2GHz bang-bang phase- and frequency-detector-based all-digital PLL with noise self-adjustment

Kyojin Choo

Digital PLLs are popular for on-chip clock generation due to their small size and technology portability. Variability tolerance is a key design challenge when designing such PLLs in an advanced CMOS technology. Environmental variations, such as mismatch, p ...

Drift Reduction for Inertial Sensor Based Orientation and Position Estimation in the Presence of High Dynamic Variability During Competitive Skiing and Daily-Life Walking

Benedikt Fasel

Nowadays inertial sensors are extensively used for gait analysis. They can be used to perform temporal event detection (i.e. step detection) and to estimate the orientation of the feet and other body segments to determine walking speed and distance. Usuall ...

GentleRain: Cheap and Scalable Causal Consistency with Physical Clocks

Willy Zwaenepoel, Calin Iorgulescu, Jiaqing Du, Amitabha Roy

GentleRain is a new causally consistent geo-replicated data store that provides throughput comparable to eventual consistency and superior to current implementations of causal consistency. GentleRain uses a periodic aggregation protocol to deter- mine whet ...

Consistency Models in Distributed Systems with Physical Clocks

Jiaqing Du

Most existing distributed systems use logical clocks to order events in the implementation of various consistency models. Although logical clocks are straightforward to implement and maintain, they may affect the scalability, availability, and latency of t ...

Robust synchronization of coupled circadian and cell cycle oscillators in single mammalian cells

Felix Naef, Cédric Gobet, Kyle Gustafson, Jonathan Bieler, Rosamaria Cannavo

Circadian cycles and cell cycles are two fundamental periodic processes with a period in the range of 1 day. Consequently, coupling between such cycles can lead to synchronization. Here, we estimated the mutual interactions between the two oscillators by t ...
