NowPrecip 2: Precipitation nowcasting in the complex terrain of Switzerland. Part I: Methods
Quarterly Journal of the Royal Meteorological Society, EarlyView.In this work we present the methods of the areal precipitation nowcasting system NowPrecip version 2. In this version a new methodology is introduced, which, although it shares philosophy and techniques with the original methodology of NowPrecip version 1, can be considered as distinct from that.

High Voltage, EarlyView.ABSTRACT Diagnosing high‐impedance ground faults (HIGFs) in distribution networks is extremely challenging because high transition resistance significantly reduces electrical signal strength and unpredictable initial fault phase angles coupled with asymmetric voltage disturbances often lead to misclassification.

On Pricing of Discrete Asian and Lookback Options under the Heston Model
, 2022 We propose a new, data-driven approach for efficient pricing of - fixed- and float-strike - discrete arithmetic Asian and Lookback options when the underlying process is driven by the Heston model dynamics. The method proposed in this article constitutes

Demographic buffering in natural populations: A multi‐level perspective
Journal of Animal Ecology, EarlyView.We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Dutch disease, unemployment and structural change
Economic Inquiry, EarlyView.Abstract We find that Dutch disease effects on unemployment are small even in a commodity‐rich economy like Australia. Using an estimated open‐economy model with frictional unemployment, we quantify how business‐cycle shocks and structural changes shape aggregate unemployment.

The big impact of small change: Fresh estimates of English wheat market integration, 1693–1893
The Economic History Review, EarlyView.Abstract Using existing and new price data sets, we provide the first estimates of market integration across England over the entire 200 years of the industrial revolution. We document a significant, though not huge, integration improvement for markets furthest from London. Full integration was achieved by the 1830s. Our price data sets vary in quality

, 2016 We derive efficient and accurate analytical pricing bounds and approximations for discrete arithmetic Asian options under time-changed Lévy processes. By extending the conditioning variable approach, we derive the lower bound on the Asian option price ...

Towards high performance stochastic arithmetic
, 2014 International audienceBecause of the finite representation of floating-point numbers in computers, the results of arithmetic operations need to be rounded.

Geostandards and Geoanalytical Research, EarlyView.Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...
