Advanced Materials, EarlyView.This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Unlocking Terahertz Steganography: Authentication of Hidden Images in Flexible Media
Advanced Materials Technologies, EarlyView.Hidden information in multilayered devices, such as steganographic portraits, is detected and authenticated using reflection‐mode terahertz time‐domain imaging. Image reconstruction relies on a dedicated figure‐of‐merit obtained by integrating the signal intensity over the time‐window associated with the reflection from the metallic mirror backing the ...

Some properties of the coupled Leonardo sequence
Hacettepe Journal of Mathematics and StatisticsIn this paper, we introduce a new Leonardo-type sequence, which we call the coupled Leonardo sequence. This sequence is defined by the non-homogeneous second-order recurrence $\mathcal{L}^{(k,t)}_{n+1} = k\mathcal{L}^{(k,t)}_{n} + t\mathcal{L}^{(k,t)}_{n-1} + Q(k,t)$, $n\ge 1$, with initial terms $\mathcal{L}^{(k,t)}_{0}=1$ and $\mathcal{L}^{(k,t)}_{1}=

A self-portrait of young Leonardo [PDF]
, 2011 One of the most famous drawings by Leonardo da Vinci is a self-portrait in red chalk, where he looks quite old. In fact, there is a sketch in one of his notebooks, partially covered by written notes, that can be a self-portrait of the artist when he was ...

Brain‐Computer Interface Training Fosters Perceptual Skills to Detect Errors
Advanced Science, EarlyView.Accurate perception of visuomotor errors underpins motor precision and learning, yet conventional behavioral training fails to improve sensitivity to subtle errors. Real‐time EEG‐based brain‐computer interface feedback targeting the error positivity component enhances perceptual learning of small errors.

On the structure and generalization of bihyperbolic Leonardo sequences
Boletim da Sociedade Paranaense de MatemáticaIn this paper, we give some properties of the bihyperbolic Leonardo numbers, among others the Binet formula, generating function formula and the general bilinear index-reduction formula which implies d'Ocagne, Vajda, Halton, Catalan, and Cassini identities.

Polymer‐Grafted Cu(II) Metal–Organic Polyhedra as Scalable, Melt‐Processable Porous Materials
Advanced Science, EarlyView.The use of a direct synthetic route to obtain polymer‐grafted Cu(II)‐based metal–organic polyhedra gives rise to a low‐cost and scalable cage. This material combines low‐temperature melting, achieving phase changes while preserving cage integrity, and high CO2 uptake exceeding 0.6 mmol g−1.
