Abstract Elucidating highly reactive intermediates in catalytic reactions relies heavily on cryogenic trapping techniques, where intermediates observed in solution are generally assumed to remain unchanged upon flash-freezing at 77 K. Herein, we demonstrate a striking exception t...

Arnold Böcklin's Self-Portrait with Death Playing the Fiddle (1872) is usually interpreted as a modern memento mori: the artist pauses at his work while Death plays a fiddle immediately behind him. Yet a closer anatomical inspection reveals another striking feature. Böcklin's own...

Beyond body mass index: A contemporary review of obesity and female infertility
Obesity is increasingly understood as a reproductive-metabolic condition that can affect female fertility across the continuum from natural conception to assisted reproductive technology (ART). Excess adiposity may disrupt hypothalamic-pituitary-ovarian regulation, insulin signal...

Background/Objectives: Older patients make up a growing share of the lung-resection workload, and C-reactive protein measured in the first days after operation is used to judge recovery. Whether the same concentration means the same thing in older men and older women is not estab...

Abstract. We investigate exact semidefinite programming (SDP) relaxations for the problem of minimizing a nonconvex quadratic objective function over a feasible region defined by both finitely and infinitely many nonconvex quadratic inequality constraints (semi-infinite QCQPs). S...

North Atlantic chlorophyll blooms modulate European hydroclimate and terrestrial productivity
Marine and terrestrial ecosystems are usually treated as separate components of the global carbon cycle, and whether variability in ocean biology reaches plant growth on land has remained unclear. Here we show that phytoplankton blooms in the high-latitude North Atlantic are link...

Nickel-Catalyzed Reductive Alkylation of Aldimines with Unactivated Alkyl Iodides
Abstract A nickel-catalyzed reductive alkylation of directing-group-free N-sulfonyl and N-aryl aldimines is reported. The reaction proceeds at ambient temperature and accommodates unactivated primary, secondary, and tertiary alkyl iodides as well as selected activated alkyl bromi...
