Terra incognita? Sport antyczny w historiografii polskiej (początki)

open access: yesSport i Turystyka, 2019
Współczesna polska historiografia sportu wyraźnie koncentruje swoją uwagę na dziejach rodzimego sportu począwszy od końca XIX w. Wydaje się to zupełnie naturalne, ale warto pamiętać, że w polskim piśmiennictwie epoki wczesnonowożytnej już w XVI w ...

Observing the signatures of AGB s-process nucleosynthesis in planetary nebulae: An origins story

open access: yesFrontiers in Astronomy and Space Sciences, 2022
I relate an anecdotal history of the beginnings of a new initiative in studies of the chemical composition of planetary nebulae: namely, investigating abundances of elements beyond the iron-peak through infrared spectroscopy.

Collecting Telecom Photons From Circular Bragg Gratings Using Optical Fibers and 3D Printed Micro‐Lenses

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 11, November 2025.
Coupling quantum light into optical single‐mode fibers is a strict requirement for quantum technological implementations. This work experimentally quantifies coupling efficiency of telecom single‐photons from circular Bragg grating cavities into silica fibers even equipped with 3D‐printed micro‐lenses.

A new find from the northern border of the Tatra Mountains

open access: yesActa Archaeologica Carpathica, 2022
Despite over a hundred years of various archaeological works, including the latest in Hučiva Cave, considering the presence of Stone age peoples, Tatra Mountains remain an archaeological terra ...

Evidence for structural crossover in the supercritical state

open access: yes, 2013
The state of matter above the critical point is terra incognita, and is loosely discussed as a physically homogeneous flowing state where no differences can be made between a liquid and a gas and where properties undergo no marked or distinct changes ...

Mitochondrial Microproteins: Emerging Regulators in Neurodevelopment and Neurodegeneration

open access: yesBioEssays, Volume 47, Issue 10, October 2025.
Mitochondrial microproteins have emerged as critical regulators of mitochondrial function. Neurons are highly dependent on mitochondria to sustain their function. Mitochondrial microproteins can be deregulated and can contribute to the pathogenesis of neurodegenerative disorders. Mitochondrial microproteins are involved in neuronal development. However,

Zwischen Herrschertypus und Epochenbegriff. Eine begriffsgeschichtliche und wissenschaftsgeschichtliche Archäologie des Burckhardtschen Pseudoneologismus ‚Soldatenkaiser‘.

open access: yesHistory of Classical Scholarship, 2022
Es gibt Begriffe, die scheinen selbsterklärend zu sein. ‚Soldatenkaiser‘ ist solch ein Fall. Seit nunmehr über einhundert Jahren insbesondere in der deutschen althistorischen Forschung zum dritten nachchristlichen Jahrhundert präsent, hat er ...

First record of terrestrial Enchytraeidae (Annelida: Clitellata) in Versailles palace's park, France [PDF]

open access: yes, 2017
France can be qualified as terra incognita regarding terrestrial enchytraeids because very little data has been recorded so far in this country. In spring and autumn 2016, enchytraeid communities were investigated in a loamy soil in a meadow located in ...

Lactobacillus reuteri‐mediated dietary xylooligosaccharides enhance jejunal cell survival via suppression of oxygen‐dependent apoptotic processes in a pig model

open access: yesiMeta, Volume 4, Issue 5, October 2025.
Interactions between functional oligosaccharides and small intestinal cells are increasingly recognized as critical for maintaining intestinal health. Using xylooligosaccharides (XOS) as a model, we demonstrate that XOS promote growth in piglets primarily by enhancing nutrient transport and increasing villus height in the jejunum.

Viajando pelo campo e pelas coleções: aspectos de uma controvérsia paleontológica Fieldtrips and collections: aspects of a Paleontology controversy

open access: yesHistória, Ciências, Saúde: Manguinhos, 2001
O campo, os museus, as coleções e os catálogos entrelaçam-se nas redes de relações estabelecidas entre os naturalistas que desenvolveram suas carreiras na construção das ciências paleontológicas no Brasil e na Argentina, na transição para o século XX ...
