Hydra groups [PDF]

, 2010
We give examples of CAT(0), biautomatic, free-by-cyclic, one-relator groups which have finite-rank free subgroups of huge (Ackermannian) distortion. This leads to elementary examples of groups whose Dehn functions are similarly extravagant.

The Effects of Different Light Spectra, UV and Extreme Temperature on the Physiology of Endosymbiotic Jellyfish Cassiopea andromeda

Marine Ecology, Volume 47, Issue 2, March/April 2026.
ABSTRACT The endosymbiotic jellyfish Cassiopea andromeda represents a yet untapped marine species that could be targeted as a new source for bioproducts, including food and feed. Also, the potential use of contained valuable ingredients, such as carotenoids and other antioxidants, under controlled aquaculture conditions might be a particularly ...

Slow-cycling stem cells in hydra contribute to head regeneration

Biology Open, 2014
Adult stem cells face the challenge of maintaining tissue homeostasis by self-renewal while maintaining their proliferation potential over the lifetime of an organism.

Towards the standardization of Hydra vulgaris bioassay for toxicity assessments of liquid samples

Ecotoxicology and Environmental Safety
The Hydra vulgaris bioassay is recognized as sensitive invertebrate test species for toxicity assessment of real-life environmental mixtures for enforcement and monitoring investigations. The purpose of this study was to characterize the intra-laboratory

Linalool acts as a fast and reversible anesthetic in Hydra.

PLoS ONE, 2019
The ability to make transgenic Hydra lines has allowed for quantitative in vivo studies of Hydra regeneration and physiology. These studies commonly include excision, grafting and transplantation experiments along with high-resolution imaging of live ...

Genetic interference with HvNotch provides new insights into the role of the Notch-signalling pathway for developmental pattern formation in Hydra

Scientific Reports
The Notch-signalling pathway plays an important role in pattern formation in Hydra. Using pharmacological Notch inhibitors (DAPT and SAHM1), it has been demonstrated that HvNotch is required for head regeneration and tentacle patterning in Hydra. HvNotch

A MiSeq-HyDRA platform for enhanced HIV drug resistance genotyping and surveillance

Scientific Reports, 2019
Conventional HIV drug resistance (HIVDR) genotyping utilizes Sanger sequencing (SS) methods, which are limited by low data throughput and the inability of detecting low abundant drug resistant variants (LADRVs).

Hydra groups

Commentarii Mathematici Helvetici, 2013
We give examples of CAT(0), biautomatic, free-by-cyclic, one-relator groups which have finite-rank free subgroups of huge (Ackermannian) distortion. This leads to elementary examples of groups whose Dehn functions are similarly extravagant. This behaviour originates in manifestations of Hercules-versus-the-hydra
