The average bit error rate (BER) for binary phase-shift keying (BPSK) modulation in free-space optical (FSO) links over turbulence atmosphere modeled by the exponentiated Weibull (EW) distribution is investigated in detail.

Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Chemical Switching: A Concept Inspired by Strategies from Biocatalysis and Organocatalysis. [PDF]
Chemical Switching is introduced as a novel technology that exploits the promiscuity of enzymatic transformations by applying small molecule organocatalytic switches (ORCAs) or gain‐of‐function protein variants. The modulation of underlying chemical principles thereby amplifies low‐rate or installs otherwise absent enzymatic activities to dominate ...

Mitochondria‐Nuclear Crosstalk: Orchestrating mtDNA Maintenance
ABSTRACT The mitochondria (mt) and nucleus engage in a dynamic bidirectional communication to maintain cellular homeostasis, regulating energy production, stress response, and cell fate. Anterograde signaling directs mt function, while retrograde signaling conveys metabolic and stress‐related changes from mt to the nucleus. Central to this crosstalk is
