Twisted speckle entities inside wavefront reversal mirrors

open access: yes, 2009
The previously unknown property of the optical speckle pattern reported. The interference of a speckle with an oppositely moving phase-conjugated speckle wave produces a randomly distributed ensemble of a twisted entities (ropes) surrounding optical ...

Numerical Prediction of Non-Cavitating and Cavitating Vortex Rope in a Francis Turbine Draft Tube

open access: yesStrojniški vestnik – Journal of Mechanical Engineering, 2011
The paper presents a prediction of vortex rope in a draft tube obtained by the numerical flow analysis. The main goal of the research was to numerically predict pressure pulsation amplitude versus different guide vanes openings and compare the results with experimental ones. Three turbulent models (SAS-SST, ω-RSM and LES) were used.

Antimicrobial Residues in a Key Cerrado River: Distribution, Persistence, and Effects on Zebrafish Embryo‐Larval Development

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The current study aimed to quantify the antimicrobials amoxicillin (AMX), cefazolin (CFZ), chloramphenicol (CHL), metronidazole (MTZ), and sulfamethoxazole (SX) in effluents and surface water of an important Cerrado river, calculate their half‐lives, and analyze their ecotoxicity following single and combined exposures.

Immune escape mechanisms revealed by multifunctional nanoprobes targeting PD‐L1 in hepatic cancer progression

open access: yesVIEW, EarlyView.
The ICGB@Apt nanoprobes are designed to specifically recognize immune checkpoint molecules such as PD‐L1, thereby enabling precise monitoring of the progression from liver cirrhosis to HC. By binding to PD‐L1 on tumor cells, ICGB@Apt visualizes immune escape events and tumor metastasis while simultaneously reflecting the dynamic interaction between ...

125 years of exploration and research at Gough's Cave (Somerset, UK) 125 ans d'exploration et de recherches à Gough's Cave (Somerset, Royaume‐Uni)

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

‘I, Me, Myself’: Selfhood and Melancholy in the Journals of Gertrude Savile (1697–1758)

open access: yesJournal for Eighteenth-Century Studies, EarlyView.
Abstract This article examines the journals of Gertrude Savile from 1727 in light of recent scholarship on early modern and eighteenth‐century melancholy. The concept had myriad associations with medicine, physiology, the imagination, and feeling, but questions remain about how melancholy during this period was considered by those outside the narrow ...

In situ aerial bioacoustic monitoring from extremely noisy drone recordings

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Aerial bioacoustic monitoring has the potential to transform biodiversity surveys by enabling rapid acoustic sampling across large and inaccessible habitats. However, its application from unmanned aerial vehicles (UAVs) has remained limited because strong rotor self‐noise overwhelms target sounds such as bird vocalisations, compromising the ...
