SC‐550: A Sintered Calcite Reference Material for In Situ U‐Pb Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points New calcite reference material (SC‐550) produced by high‐temperature and high‐pressure sintering of nano‐particulate powder from a microbial limestone. Homogeneous U content (2.3 ± 0.4 μg g‐1) and U‐Pb isotope ratios (< 0.6% RSD for 207Pb/206Pb; < 3% RSD for 238U/206Pb).

Ibis, EarlyView.Hatching failure represents a significant and growing barrier to reproductive success in threatened birds and yet is often poorly understood. Populations of the Eurasian Curlew Numenius arquata in the United Kingdom and Republic of Ireland have experienced significant declines over recent decades, and low breeding productivity is a major barrier to ...

Journal of Intellectual Disability Research, EarlyView.ABSTRACT Background Adults with intellectual disability experience significant health issues that increase with age. Longitudinal analyses offer important evidence on how the trajectories of these conditions' develop and change. Methods Data were drawn from five waves of IDS‐TILDA, with a nationally representative sample of over 700 adults with ...

Mixing It Up: Inflation at Risk
Journal of Money, Credit and Banking, EarlyView.Abstract Understanding how risk factors shape the economic outlook is essential for guiding policy decisions. This paper develops a flexible framework that decomposes distributional risk forecasts of macro‐economic variables into underlying contributions and supports the construction of interpretable risk measures.

Accessible range of motion characterisation of the OpenFlexure microscope
Journal of Microscopy, EarlyView.Abstract For any hardware to remain accessible, calibration techniques which rely on low‐cost and obtainable materials such as easily manufactured test slides are necessary. We present a method of measuring the range of motion of the OpenFlexure Microscope using minimal equipment and a computationally light algorithm suitable for running on embedded ...

The Evolution of Interest‐Rate Models: From the Yield Curve to the Swaption Cube
Journal of Economic Surveys, EarlyView.ABSTRACT Interest‐rate modelling is often taught as a catalogue of competing stochastic equations, obscuring why models were created and why modern sell‐side desks use several simultaneously. This survey reorganises the field around five layers of a pricing architecture: curve construction; arbitrage‐free dynamics; volatility‐smile representation ...

Dynamic capital allocation in general insurance
Journal of Risk and Insurance, EarlyView.Abstract This paper provides a model for allocating capital to different insurance lines with varying development periods for a value‐maximizing insurance company. In our model, the company makes capitalization and exposure decisions considering its capital level and its relevant loss history.
