Robust Mean–Variance Portfolio Optimization: Mean–Variance–Variance Criterion Versus Mean–Variance–Standard Deviation Criterion

Mathematical Finance, EarlyView.
ABSTRACT We study a dynamic portfolio optimization problem under the mean–variance–variance (M‐V‐V) criterion proposed by Maccheroni et al. It is an analogue of the Arrow–Pratt approximation to the well‐known smooth ambiguity model. Under the standard Black–Scholes framework, we derive fully explicit equilibrium investment strategies in which a DM's ...

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

On the dissipation layer of radial bearings

International Journal of Mathematics and Mathematical Sciences, 1988
The dissipation boundary layer of certain radial bearings is identified. It is shown that, under certain conditions, the temperature outside this layer is constant.

Outcomes in Recurrent Focal Segmental Glomerulosclerosis Post‐Kidney Transplantation Treated With Therapeutic Plasma Exchange: A Retrospective Cohort Study

Journal of Clinical Apheresis, Volume 41, Issue 4, August 2026.
ABSTRACT Recurrence of focal segmental glomerulosclerosis (FSGS) following kidney transplantation remains a significant cause of allograft loss. Much remains unknown about the efficacy of apheresis treatments and the factors that determine favorable treatment outcomes.

Ultrafast opto-magnetic effects in the extreme ultraviolet spectral range

Communications Physics
Coherent light-matter interactions mediated by opto-magnetic phenomena like the inverse Faraday effect (IFE) are expected to provide a non-thermal pathway for ultrafast manipulation of magnetism on timescales as short as the excitation pulse itself.
