Deep reinforcement learning for multi‐restart metaheuristics: an environment design for a hybrid of unbiased exploratory search and covariance matrix adaptation evolution strategy

International Transactions in Operational Research, EarlyView.
Abstract Multi‐restart metaheuristics can be highly effective for complex optimization problems, yet their performance depends critically on how restarts and algorithmic parameters are selected. This paper introduces a reinforcement learning approach for managing restart‐level decisions and parameter configurations in the UES–CMA‐ES hybrid ...

Bimekizumab efficacy using IHS4 outcomes in hidradenitis suppurativa: Results from BE HEARD I and II

Journal of the European Academy of Dermatology and Venereology, EarlyView.
The majority of bimekizumab‐treated patients shifted from severe to mild and moderate IHS4 stages, and nearly 25% achieved an IHS4 of 0 by Week 48. Bimekizumab led to clinically meaningful improvements across IHS4 outcome measures. These data highlight an opportunity to address the need for effective treatments against draining tunnels.

Shark preferences: Only subtle effects of electromagnetic field exposure and substrate type on small‐spotted catshark (Scyliorhinus canicula) behaviour

Journal of Fish Biology, EarlyView.
Abstract Offshore wind energy plays a crucial role in the transition to low‐carbon power generation. The expansion of offshore wind farms (OWFs) introduces anthropogenic electromagnetic fields (EMFs) from subsea power cables. Elasmobranchs, including sharks and rays, are sensitive to natural electric and magnetic fields used for navigation and prey ...

The expected inflation risk premium in the U.S. stock market

Journal of Financial Research, EarlyView.
Abstract This article studies how expected inflation risk affects asset prices. We propose an ex‐ante, tradable proxy for this risk, derived from the term spread of gold futures prices. Using cross‐sectional and time series asset pricing tests, we show how an increase in expected inflation risk lowers contemporaneous prices and raises equity returns ...

Interest Rate Pegs and the Reversal Puzzle: On the Role of Anticipation

Journal of Money, Credit and Banking, EarlyView.
Abstract We revisit the reversal puzzle: a counterintuitive contraction of inflation in response to an interest rate peg. We show that its occurrence is intimately related to the degree of agents' anticipation. If agents perfectly anticipate the peg, reversals occur depending on the duration of the peg.

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.

Countercyclical Return Expectations: Evidence from the Livingston Survey

Journal of Money, Credit and Banking, EarlyView.
Abstract This paper shows that forecasts from professional economists in the Livingston survey imply countercyclical variation in expected excess returns on U.S. stocks. These expectations are approximately rational and strongly positively correlated with expected excess returns from the log‐utility investor of Martin (2017), the habit model of ...

Networked Regional Resilience: Diffusion of Risk and Adaptation Across Interconnected Regions

Journal of Regional Science, EarlyView.
ABSTRACT Regions face not only direct exposure to economic and physical shocks but also indirect consequences of actions in interconnected regions. This paper examines how socio‐spatial networks shape regional resilience to contagious shocks through dynamic feedback between risk diffusion and adaptation diffusion.
