Democratising Multi‐Projector Displays
Computer Graphics Forum, EarlyView.Spatially augmented reality (SAR) transforms large, surround, collaborative experiences out of VR/AR headsets to the real world by merging content from projectors with the physical environment. This detailed state‐of‐the‐art survey reports on the advancements in multi‐projector aggregation and hardware technologies used to achieve SAR and build ...

The effect of fast and regeneration in light versus dark on regulation in the hydra-algal symbiosis [PDF]
Green hydra are able to regenerate tentacles after fast durations which cause brown, i.e., asymbiotic, hydra to fail completely, but the presence of endosymbiotic algae does not always enhance regeneration in fasted hydra.

COMMITMENT DURING NEMATOCYTE DIFFERENTIATION IN HYDRA [PDF]
, 1981 Nematocytes in Hydra differentiate from interstitial stem cells. Desmonemes differentiate mainly in the distal half of the body column while stenoteles differentiate predominantly in the proximal half.

The Russian Review, EarlyView.Abstract This article examines the assassination of Duma representative Mikhail Gertsenshtein in July 1906 as the pivotal moment for the emergence of the concept of “right‐wing terrorism” (pravyi terrorizm) in the Russian Empire. Drawing on court documents, police files, and censorship reports, this article argues that the significance of the ...

Hydra tropomyosin TROP1 is expressed in head-specific epithelial cells and is a major component of the cytoskeletal structure that anchors nematocytes [PDF]
, 1994 A cDNA clone encoding a 253 amino acid tropomyosin was isolated from Hydra in a differential screen for headspecific genes. The Hydra tropomyosin gene, designated trop1, is a single copy gene, lacks introns and is strongly expressed in tentacle-specific ...

The Biological Bulletin, 1997 Embryogenesis in hydra includes a variable period of dormancy; and this period, as well as subsequent stages through hatching, takes place within a thick cuticle that hinders observation. Thus, although the early stages of development have been well-characterized qualitatively, the middle and later stages are only poorly understood.

Zoologica Scripta, EarlyView.ABSTRACT Hadal environments (> 6000 m ocean depths) are often viewed as isolated locations with high species endemism due to limited dispersal. However, molecular studies continue to reveal greater complexity that questions historical perceptions. Recent population genetic studies focused on scavenging amphipods have identified broadly distributed ...

, 1986 The proliferative capacity of gland cells in Hydra attenuata was investigated. The results indicate that both gland cell proliferation and interstitial cell differentiation to gland cells contribute to the maintenance of the whole population.

Biophysical Journal, 2016 Sheets of epithelial cells allow animal tissues to define inside and outside, and as such are arguably the fundamental building block of metazoan life. Because of this topological role, the folding, stretching, and on occasion disruption of epithelial sheets is a central feature of both embryonic development and tissue regeneration.

Heterokairic Genes and the Eco‐Evo‐Devo of Timing
Evolution &Development, Volume 28, Issue 2, June 2026.Heterokairic genes as the bridge (Heterokairic Pathways?): Heterokairic genes are heterochronic regulators whose activity is modulated by environmental conditions. External cues (e.g., temperature, nutrition, oxygen, density: yellow box) are sensed (yellow arrows) and converted into endocrine and metabolic signals (purple box and arrow into fish's ...
