Model Ambiguity versus Model Misspecification in Dynamic Portfolio Choice
The Journal of Finance, Volume 81, Issue 3, Page 1741-1795, June 2026.ABSTRACT We study aversion to model ambiguity and misspecification in dynamic portfolio choice. Risk‐averse investors (relative risk aversion γ>1$\gamma > 1$) fear return persistence, while risk‐tolerant investors (0<γ<1$0<\gamma <1$) fear mean reversion, when confronting model misspecification concerns of identically and independently distributed (IID)

Validation of machine learning based scenario generators
Journal of Risk and Insurance, Volume 93, Issue 2, Page 508-533, June 2026.Abstract Machine learning (ML) methods are becoming increasingly important for designing economic scenario generators for internal models. Validating data‐driven models requires different methods than validating classical, theory‐based models. We discuss two novel aspects of such validation: first, checking the multivariate distribution of risk factors,

Sleep Deprivation in Mice: Looking Beyond the Slow Wave Rebound
Journal of Sleep Research, Volume 35, Issue 3, June 2026.ABSTRACT Sleep is a fundamental process supporting the dynamic regulation of neural function. Emerging methods have proposed that the aperiodic components of brain signals (such as the spectral slope, spectral intercept, and spectral knee), in addition to entropy‐based measures, offer robust empirical markers of neural states.

Evolutionary and environmental drivers of dry‐season deciduousness in a legume genus
New Phytologist, Volume 250, Issue 6, Page 3631-3645, June 2026.Summary Leaf deciduousness is a key drought‐avoidance strategy in tropical flora, reducing water loss during seasonal dry periods. While winter‐deciduousness in temperate regions is well‐understood, the evolutionary and environmental drivers of dry‐season deciduousness remain poorly explored.

New Phytologist, Volume 250, Issue 6, Page 3716-3731, June 2026.Summary Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (gmin), which is highly relevant since it informs on the water depletion dynamics under stress.

Summary The evolution of C4 photosynthesis requires biochemical innovations to be coordinated with anatomical modifications.
