A Mechanical Planar Chiral Rotaxane Induces Single‐Handed Helicity in a Twisted Perylene Diimide

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
A mechanical planar chiral rotaxane (Rmp) is used to induce single‐handed helical chirality (M) in a perylene diimide chromophore, resulting in persistent circular dichroism (CD) and circularly polarised luminescence (CPL). ABSTRACT The twisting of chromophores such as perylene diimides (PDIs) into helical structures affords chiroptical properties from

Light Chain Monoclonal Gammopathy of Undetermined Significance: Diagnosis, Biology, and Clinical Management

European Journal of Haematology, EarlyView.
ABSTRACT Light chain monoclonal gammopathy of undetermined significance (LC‐MGUS) is defined by an abnormal serum free light chain ratio and elevated involved light chain in the absence of a detectable immunoglobulin heavy chain on immunofixation and of end‐organ damage attributable to a plasma cell disorder.

Marine heatwaves shape size‐dependent thermal exposure, habitat use and marine residency in Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Marine heatwaves (MHWs) are increasing in high‐latitude oceans, yet behavioural responses of anadromous fishes to these potential stressors during short marine feeding seasons remain poorly understood. We combined acoustic telemetry (internal temperature and depth) with satellite‐derived sea surface temperature data to quantify Arctic char ...

Performance Evaluation of LTE/LTE-A DRX: A Markovian Approach

IEEE Internet of Things Journal, 2016
Long-term evolution (LTE)/long-term evolution advanced (LTE-A) are emerging communication technologies on the way toward 5G telecommunication systems. Ubiquitous adoption of connectivity in between different kinds of sensors, wearable devices, and other low-power equipment raises an importance of the energy-efficient wireless communications. In LTE/LTE-

Atlantic salmon (Salmo salar) aquaculture in a changing climate: Quantitative insights from industry records and climate projections

Journal of Fish Biology, EarlyView.
Abstract Predicting and understanding the implications of climate change on Atlantic salmon (Salmo salar) aquaculture is a fundamental step to understanding risk and mitigating potential impacts. Here, we statistically downscale established climate models using satellite‐based sea surface temperature data and in situ industry measurements to inform ...
