Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

Advanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Speeding up tensor based recommenders with clustered tag space and improving quality of recommendations with Non-negative tensor factorization [PDF]

, 2011
Social tagging facilitates users to annotate and categorizeitems (Web links, pictures, movies, etc.).Assigned tags express the user preferences. Socialtagging systems (STS) have become popular hencevarious tag based recommenders have been developed.The ...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

AI-Assisted Multiview Cartoon Character Modeling: Physics-Consistent Inverse Rendering for Dynamic-Backlight Light-Field 3D Display

Photonics
Three-dimensional display is fundamentally a problem of reconstructing view-dependent optical rays rather than presenting planar images. Multilayer light field display provides an effective panel-based route for 3D scene reconstruction, but it remains ...

On Ambisonic Source Separation With Spatially Informed Non-Negative Tensor Factorization

IEEE/ACM Transactions on Audio, Speech, and Language Processing
This article presents a Non-negative Tensor Factorization based method for sound source separation from Ambisonic microphone signals. The proposed method enables the use of prior knowledge about the Directions-of-Arrival (DOAs) of the sources, incorporated through a constraint on the Spatial Covariance Matrix (SCM) within a Maximum a Posteriori (MAP ...

Nonnegative factorization and the maximum edge biclique problem [PDF]

Nonnegative matrix factorization (NMF) is a data analysis technique based on the approximation of a nonnegative matrix with a product of two nonnegative factors, which allows compression and interpretation of nonnegative data. In this paper, we study the

Nanoconfinement‐Induced Second‐Harmonic Circular Dichroism via Chirality–Ferroelectric Coupling

Advanced Functional Materials, EarlyView.
Nanoconfinement of a ferroelectric nematic liquid crystal within a chiral nanoporous sponge yields an enhanced second‐harmonic generation circular dichroism (|gSHG–CD| ≈ 1.1). Polarization‐resolved analysis suggests an additional magnetic‐dipole‐associated nonlinear contribution under nanoconfinement, highlighting chirality–ferroelectric coupling as a ...

Bayesian multi-tensor factorization [PDF]

, 2016
We introduce Bayesian multi-tensor factorization, a model that is the first Bayesian formulation for joint factorization of multiple matrices and tensors. The research problem generalizes the joint matrix-tensor factorization problem to arbitrary sets of
