Kant's Solution to the Trilemma of Concept Formation

European Journal of Philosophy, EarlyView.
Abstract According to a widespread assumption, Kant's logical account of concept formation starts with comparison, where the latter involves concepts. On this assumption, the formation of a concept presupposes other concepts, so that the argument is threatened either by circularity, regress, or break‐off.

Application of Noise2Inverse and adaptation (Noise2Phase) to single‐mask x‐ray phase contrast micro‐computed tomography

Journal of Microscopy, EarlyView.
Abstract X‐ray phase contrast imaging (XPCI), when implemented in micro‐computed tomography (micro‐CT) mode, offers high‐contrast 3D imaging of weakly‐attenuating material samples. In the so‐called single‐mask edge illumination approach, a mask with periodically spaced transmitting apertures is used to split the x‐ray beam into narrow beamlets; when ...

Advances in high‐resolution cryo‐volume electron microscopy (cvEM) imaging for unicellular and multicellular organisms

Journal of Microscopy, EarlyView.
Abstract Cryo‐Focused Ion Beam Scanning Electron Microscopy (cryoFIB‐SEM) using samples fixed by high‐pressure freezing uniquely enables high‐resolution cryo‐volume Electron Microscope (cvEM) images of cell ultrastructure to be obtained from whole cells and complex tissues in their near native state. As the freezing process also preserves fluorescence,

Sleep and cardiac autonomic modulation in older adults: Insights from an at‐home study with auditory deep sleep stimulation

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it
