Chemistry – A European Journal, EarlyView.Membrane‐forming phospholipids are produced in cells via enzymatic diacylation. Here, we show that direct aminolysis of acyl thioesters with diamino acids in aqueous environments enables the synthesis of diacylated amino acids (DAAAs), which spontaneously self‐assemble into robust phospholipid‐like vesicles across a broad range of pH and temperature ...

Chemistry – A European Journal, EarlyView.The power of catalytic promiscuity: The enantioselective conjugate hydrocyanation of enals remains a long‐standing challenge for biocatalysis. Here, we report the redesign of 2‐deoxy‐D‐ribose‐5‐phosphate aldolase for the asymmetric conjugate hydrocyanation of aromatic enals, expanding the reaction scope of iminium‐based enzyme catalysis to include an ...

Two particles with zero-range interaction in a magnetic field
Physics Letters B, 2021 Energy levels are investigated for two charged particles possessing an attractive, momentum-independent, zero-range interaction in a uniform magnetic field.

European Journal of Organic Chemistry, EarlyView.The transfer semihydrogenation of long‐chain alkynyl alcohols catalyzed by Pd–imidazo[1,5‐a]pyridine carbene (IPC) PEPPSI‐type complexes, along with the subsequent derivatization of the resulting alkenyl alcohols into the corresponding fatty acids, was investigated.

P-Adic Transcendental Numbers [PDF]
Proceedings of the American Mathematical Society, 1990 Explicit sets of cardinality 2'o of p-adic numbers which are algebraically independent over Qp are constructed. Let Qp be the p-adic completion of Q for a prime p. Let Qp be the algebraic closure of Qp, and Cp be its p-adic completion which is an algebraically closed field of cardinality 2"O .

Food Bioengineering, EarlyView.ABSTRACT Artificial intelligence (AI) has emerged as a paradigm‐shifting force in enzyme engineering, enabling data‐driven prediction of catalytic activity, stability, and substrate specificity. By integrating large‐scale datasets from structured databases (e.g., PDB, BRENDA) and high‐throughput experimentation (e.g., deep mutational scanning ...

Multiplicative processes as a source of fat-tail distributions
Heliyon, 2020 Many works in the literature are in favour of the universality of power-laws. However, more recently, a significant amount of research has exposed more subtle details about this subject.

Transcendentalism of curves and of numbers [PDF]
, 2021 Lindemann's proof that the number e can not be the root of an algebraic equation with algebraic coefficients and algebraic exponents furnishes us with an example of a curve, namely y-e[superscirpt x] which has only one algebraic point, that is, only one point each of those coordinates is algebraic.

Health Economics, EarlyView.ABSTRACT Primary medical care has traditionally been provided by small organisations. Recent policy developments in many countries have encouraged larger practices in the hope of benefiting from increasing returns to scale, but there is little research evidence to support this.

Terahertz All‐Dielectric Maxwell Fisheye Lens Waveguide Crossings via Transformation Optics
Laser &Photonics Reviews, EarlyView.All‐silicon terahertz waveguide crossings based on Maxwell fisheye lenses are reshaped using transformation optics to interface with planar waveguides while reducing mode mismatch. Realized via subwavelength perforations in a single etching step, 2 × 2 and 3 × 3 crossings achieve broadband transmission with low loss and ultralow crosstalk across 220 ...
