Phyllotaxis: Leaf arrangement on a horizontal branch and crystallographic borders
Vestnik MGTUPhyllotaxis is an orderly arrangement of leaves on plant stems and branches. The natural reason of this arrangement is that each species based on the habitat conditions in the course of evolution in one way or another solved the problem of optimising the

Advanced Functional Materials, EarlyView.The study proposes a 1‐bit programmable metasurface based on flip‐disc display, named flip‐disc metasurface (FD‐MTS). This new design enables ultralow energy consumption while maintaining coding patterns. It also exhibits high scalability and multifunctional flexibility.

Evolution of horizontal branch stars with extension [PDF]
Astrophysics and Space Science, 1990 The details of the evolution of a low-mass horizontal branch star through the asymptotic giant phase with the assumption of first an extended atmosphere and second with extended and mass including atmosphere are given in comparison with the evolution of the same model without extension. © 1990 Kluwer Academic Publishers.

Horizontal Branch Stars and the Ultraviolet Universe [PDF]
, 2009 Extremely hot horizontal branch (HB) stars and their progeny are widely considered to be responsible for the "ultraviolet upturn" (or UVX) phenomenon observed in elliptical galaxies and the bulges of spirals. Yet, the precise evolutionary channels that lead to the production of these stars remain the source of much debate.

Advanced Healthcare Materials, EarlyView.A simplified, co‐culture‐free protocol for kidney organoids that generate segmented nephrons, including collecting ducts, has been developed. Early low‐dose RA with FGF9 induces balanced anterior–posterior IM patterning and dual UE/MM lineage commitment. BMP7 enhances nephron progenitor maturation.

The Spectral Evolution along the Z track of the Bright Neutron Star X-ray Binary GX 17+2
, 2011 Z sources are bright neutron-star X-ray binaries, accreting at around the Eddington limit. We analyze the 68 RXTE observations (270 ks) of Sco-like Z source GX 17+2 made between 1999 October 3-12, covering a complete Z track.

Advanced Healthcare Materials, EarlyView.This study introduces the first miniaturized, patient‐specific carotid artery model created via 3D printing using GelMA with embedded vascular cells. Combining CFD, PIV, and flow perfusion, the model replicates anatomically dependent hemodynamics and cellular responses.

Advanced Healthcare Materials, EarlyView.Injectable POEGMA‐DA hydrogels, dual‐crosslinked via dopamine self‐polymerization and dynamic hydrazone bonds, provide a safer alternative to invasive wound closure methods and toxic bioadhesives. Mimicking skin‐like mechanics, they achieve effective tissue adhesion for acute dermal wounds, supporting improved healing outcomes, including reducing ...
