Computing semiparametric bounds on the expected payments of insurance instruments via column generation

, 2016
It has been recently shown that numerical semiparametric bounds on the expected payoff of fi- nancial or actuarial instruments can be computed using semidefinite programming. However, this approach has practical limitations. Here we use column generation,

The SPoRC Stock Assessment Package: A Generalized Next‐Generation Platform to Assess Spatial, Age and Sex‐Structured Populations

Fish and Fisheries, Volume 27, Issue 3, Page 754-770, May 2026.
ABSTRACT Fisheries managers increasingly rely on stock assessment models to provide sustainable management advice, which must balance complex and competing objectives. Although assessment models necessitate simplifying assumptions, there is increasing recognition to improve the integration of realistic biological and fishery dynamics. While ongoing and

Ambiguity Aversion, Portfolio Choice, and Life Expectancy

International Economic Review, Volume 67, Issue 2, Page 633-655, May 2026.
ABSTRACT This paper studies how wealth and aging affect portfolio choices in a life‐cycle model with ambiguity aversion. Ambiguity aversion implies wealthier and older agents are endogenously more optimistic about risky asset returns, relative to poorer/younger agents. As life expectancy grows, old agents become even more optimistic, while young agents

Evaluating Bayesian Morphological Clocks for Estimating a Dated Phylogeny in a Relict and Fossil‐Rich Family of Wasps (Hymenoptera, Chrysidoidea)

Zoologica Scripta, Volume 55, Issue 3, Page 448-463, May 2026.
ABSTRACT In recent years, a wide array of tools originally developed for molecular dating analyses has been adapted for use within a morphological clock perspective. This is of paramount relevance for taxonomic groups that cannot be sampled in forms suitable for DNA extraction.

Laboratory Experiments on Savannah and European Boreal Forest Fire Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Landscape fire is among the largest sources of aerosols and trace gases globally. However, the emissions are highly variable and strongly affected by the type of biomass and combustion characteristics. We investigated the effect of combustion characteristics on the burning emissions from three biomass types: woody plants and grasses from ...

Improved Dust Microphysical Retrieval From LiDAR by Introducing a Priori Constraints From In Situ and Laboratory Measurements

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The accuracy of height‐resolved dust microphysical retrieval from LiDARs has been greatly improved by the recently developed BOREAL (Basic algOrithm for REtrieval of Aerosol with LiDAR) algorithm which describes non‐spherical dust particles with the Irregular‐Hexahedral (IH) model and inverts 3β (backscattering at 355, 532, and 1,064 nm) + 2α (
