Estimations of the weighted power mean by the Heron mean (Research on structure of operators using operator means and related topics)

open access: yesEstimations of the weighted power mean by the Heron mean (Research on structure of operators using operator means and related topics)
As the means generalizing the arithmetic and the geometric ones, the power mean and the Heron mean are known. For positive real numbers a and b, the weighted power mean P_{t, q}(a, b) and the weighted Heron mean K_{t, q}(a, b) for tin [0, 1] and qin mathbb{R} are defined by P_{t, q}(a, b)={(1-t)a^{q}+tb^{q}}^{frac{1}{q}} and K_{t, q}(a, b)= (1-q)a^{1-t}

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Norms and compactness of operators on absolute weighted mean summable

open access: yes, 2016
In a recent paper we characterized the classes of triangular matrix transformations mapping from the spaces vertical bar(N) over bar (p)vertical bar and vertical bar(N) over bar (theta)(p)vertical bar (k) into the spaces vertical bar(N) over bar (theta)(p)vertical bar (k) and vertical bar(N) over bar (q)vertical bar , respectively, where the spaces ...

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

open access: yesAdvanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.
