Aromatic Polyimine‐Derived Carbon Membranes for Efficient Hydrogen Separation
Small, EarlyView.A polyimine with free‐volume‐introducing kinked structures was used as a precursor for high‐performance carbon membranes. Changing the pyrolysis protocol affects the carbon structure, yielding membranes with high permeance and enhanced selectivity for key industrial gas pairs (H2/N2, H2/CH4), offering a practical route toward efficient and reliable ...

Nocturnal Behavior of Wintering Common Cranes (Grus grus) Under Varying Environmental Conditions
Integrative Zoology, EarlyView.For diurnal species, nighttime represents a critical ecological boundary. Understanding the ecological determinants of nocturnal activity in taxa traditionally regarded as inactive after dusk is essential for elucidating the adaptive significance of nighttime behavior. We examined how night phase, nocturnal brightness (moon illumination and cloud cover)

Kant on Rational Reference: Theology as transcendental philosophy
European Journal of Philosophy, EarlyView.Abstract The Critical Kant famously held that our cognition requires intuition, or essentially singular representation. Kant is also often understood as taking a dismissive attitude toward his rationalist predecessors' accounts of how we cognize singulars or individuals.

Post-translational modification of PII signal transduction proteins
Frontiers in Microbiology, 2015 The PII proteins constitute one of the most widely distributed families of signal transduction proteins in nature. They are pivotal players in the control of nitrogen metabolism in bacteria and archaea, and are also found in the plastids of plants. Quite

Fractional-Order PII1/2DD1/2 Control: Theoretical Aspects and Application to a Mechatronic Axis
Applied Sciences, 2021 Fractional Calculus is usually applied to control systems by means of the well-known PIλDμ scheme, which adopts integral and derivative components of non-integer orders λ and µ. An alternative approach is to add equally distributed fractional-order terms

The FEBS Journal, EarlyView.We present the first crystal structures of human NIF3, revealing a dynamic, hexameric ring with a central cavity regulated by flexible insertion domains. Crucially, human NIF3 features a mononuclear zinc‐binding site, marking a distinct evolutionary departure from the dinuclear centers of bacterial homologs.
