Dobrindt argumentiert die Entscheidung des Gerichts, die Zurückweisung an der Grenze sei illegal gewesen, sei eine Einzelfall­entscheidung und daher nicht generell anwendbar.
Nehmen wir diesen Einwand mal kurz ernst. Einzelfall bedeutet: es gab besondere Umstände. Nun, diese können im vorliegenden Fall kaum extern sein, die aktuelle Bedrohungslage hat sich nicht für diese Menschen spontan geändert, Sonnenstand, aktuelle Stimmungslage der Union etc dürfen keinen Einfluß haben, d.h. der …

Enantioselective radical reactions can be induced by electron spin polarization: A quantum mechanism for Nature's emergent homochirality?
Biomolecules that constitute life on Earth are chiral, but the precise mechanism by which homochirality emerged remains a mystery. In this work it is demonstrated that reactions of radical pairs, where one of the radical electron spins is polarised, can be enantioselective. This phenomenon arises from transient coherent quantum dynamics of the radical pair electron spins, which is known to occur even in warm and noisy condensed phase environments, where energetic perturbations much smaller than…

High-definition 3D suspended Archimedean spiral with broadband, spatially extended, and single-handed optical chirality enhancement in Vis-NIR range
3D plasmonic structures can provide giant optical chirality (C) in the near field, enabling strong interactions with enantiomers for chiral sensing applications. However, these structures face several limitations, including narrow operational bandwidth constrained by resonance, flipping handedness of C around the resonant frequency, spatially confined distribution of C, and difficulty in trapping enantiomers. Our numerical predictions reveal that a 3D plasmonic Archimedean spiral (AS) exhibits …

Velocity rotation curves in the gravimagnetic dipole spacetime
The gravimagnetic dipole spacetime consists of two counter-rotating black holes of equal mass connected by a Misner string. For a particular distance in between them, the string is tensionless with the black holes at equilibrium with each other. The geodesics of relativistic massive, or massless particles are considered, leading to the identification of circular rotation trajectories. The velocities of these trajectories are computed.

Unobtrusive Reflectance Photoplethysmography for Detecting and Severity Grading of Sleep Apnea via Oxygen Desaturation Index
Sleep apnea is a common chronic sleep-related disorder which is known to be a comorbidity for cerebro- and cardio-vascular disease. Diagnosis of sleep apnea usually requires an overnight polysomnography at the sleep laboratory. In this paper, we used a wearable device which measures reflectance photoplethysmography (PPG) at the wrist and upper arm to estimate continuous SpO2 levels during sleep and subsequently derive an oxygen desaturation index (ODI) for each patient. On a cohort of 170 patie…

Development of a laser stabilized on an ultra-stable silicon cryogenic Fabry-Perot cavity for dark matter detection
Astrophysical observations suggest the existence of an unknown kind of matter in the Universe, in the frame of the $Λ$CDM model. The research field of dark matter covers an energy scale going from massive objects to ultra-light scalar fields, which are the focus of the present work. It is supposed that ultra-light scalar fields affect the length of objects, whereas the speed of light stays unchanged. It follows that Fabry-Perot cavities are ideal tools for ultra-light dark matter detection sin…

For more than a century, putrid fumes emanated from
the “sewer of the Ruhr”,
creating a pungent whiff that assaulted towns throughout Germany’s industrial heartland.
But today, the Emscher bears little resemblance to Europe’s dirtiest river.
Water that used to be fouled by factory waste and human excrement have been free from effluent since 2021.
The river system, the main part of which was once considered biologically dead, is witnessing the return of an abun…
