Signal‐to‐noise and spatial resolution in in‐line imaging. 3. Optimization using a simple model
Journal of Synchrotron Radiation, EarlyView.Geometrical magnification and X‐ray energy are optimized with respect to spatial resolution, contrast, noise, radiation dose and other image quality characteristics. The optimization is performed using a simple theoretical model of a homogeneous edge feature embedded in a bulk uniform sample, and the resulting generic analytical expressions for image ...

Medical and Veterinary Entomology, EarlyView.A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

Order-disorder phase change in embedded Si nano-particles
, 2011 We investigated the relative stability of the amorphous vs crystalline nanoparticles of size ranging between 0.8 and 1.8 nm. We found that, at variance from bulk systems, at low T small nanoparticles are amorphous and they undergo to an amorphous-to ...

Low Parsons–Zobel slope of metal–solution interfaces: A theoretical comparison of three causes
AIChE Journal, Volume 72, Issue 2, February 2026.Abstract Rational design of electrochemical energy conversion and storage devices hinges on a fundamental understanding of the electrical double layer (EDL) at the electrode–electrolyte interface. The classical Gouy–Chapman–Stern model of EDL predicts a unity Parsons–Zobel (PZ) slope, which is derived from the relation between inverse measured ...

Time-Response Functions of Mechanical Networks with Inerters and Causality
, 2017 This paper derives the causal time-response functions of three-parameter mechanical networks that have been reported in the literature and involve the inerter-a two-node element in which the force-output is proportional to the relative acceleration of ...

Seamless Short‐ to Mid‐Term Probabilistic Wind Power Forecasting
Wind Energy, Volume 29, Issue 2, February 2026.ABSTRACT This paper brings a new understanding to the relative importance of different uncertainty sources across forecast horizons up to 7 days ahead. It presents a method for probabilistic wind power forecasting that quantifies uncertainty from weather forecasts and weather‐to‐power conversion separately.

Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Intermittent flow is a widely recognized phenomenon across various fields, characterized by the spatial‐temporal fluctuations of the two‐phase topology. However, its implications for solute dispersion and mixing remain insufficiently understood.

Mathematical Modeling of Measured Recalescence Velocities
Mathematical Methods in the Applied Sciences, Volume 49, Issue 2, Page 977-988, 30 January 2026.ABSTRACT A moving‐boundary problem of synchronous directional and volumetric solidification in undercooled liquid drops is formulated and solved. Directional solidification is caused by the temperature gradient along the spatial direction, whereas volumetric growth of new phase elements is caused by the melt undercooling ahead of the phase transition ...
