Bose–Einstein condensation of photons in an erbium–ytterbium co-doped fiber cavity
Nature Communications, 2019 Bose–Einstein condensates were demonstrated at low temperatures, mostly with ultracold bosonic atoms. Here, the authors demonstrate BEC of photons in a standard 1D erbium–ytterbium co-doped fiber cavity at, below and above room temperature.

ERNA and Friedman's Reverse Mathematics [PDF]
The Journal of Symbolic Logic, 2011 AbstractElementary Recursive Nonstandard Analysis, in short ERNA, is a constructive system of nonstandard analysis with a PRA consistency proof, proposed around 1995 by Patrick Suppes and Richard Sommer. Recently, the author showed the consistency of ERNA with several transfer principles and proved results of nonstandard analysis in the resulting ...

Diversity and Emerging Roles of Enhancer RNA in Regulation of Gene Expression and Cell Fate
Frontiers in Cell and Developmental Biology, 2020 Enhancers are cis-regulatory elements in the genome that cooperate with promoters to control target gene transcription. Unlike promoters, enhancers are not necessarily adjacent to target genes and can exert their functions regardless of enhancer ...

Environmental RNA as a Tool for Marine Community Biodiversity Assessments
Scientific Reports, 2022 Microscopic organisms are often overlooked in traditional diversity assessments due to the difficulty of identifying them based on morphology. Metabarcoding is a method for rapidly identifying organisms where Environmental DNA (eDNA) is used as a ...

Metabarcoding monitoring analysis: the pros and cons of using co-extracted environmental DNA and RNA data to assess offshore oil production impacts on benthic communities [PDF]
PeerJ, 2017 Sequencing environmental DNA (eDNA) is increasingly being used as an alternative to traditional morphological-based identification to characterize biological assemblages and monitor anthropogenic impacts in marine environments.

A role for p53 in telomere protection
Molecular & Cellular Oncology, 2017 Telomeres cap the ends of chromosomes and are crucial for genome stability. The p53 protein (TP53) is a vital tumor suppressor, activating the transcription of numerous genes in response to cell stress.

Wanted dead or alive? Using metabarcoding of environmental DNA and RNA to distinguish living assemblages for biosecurity applications. [PDF]
PLoS ONE, 2017 High-throughput sequencing metabarcoding studies in marine biosecurity have largely focused on targeting environmental DNA (eDNA). DNA can persist extracellularly in the environment, making discrimination of living organisms difficult.

Tunable degree of polarization in a figure-8 fiber laser
AIP Advances, 2022 We experimentally study a fiber loop laser in a figure-8 configuration and explore the dependency of the degree of polarization on controlled parameters. To account for the experimental observations, a mapping is derived to evaluate the polarization time
