AFDGCF: Adaptive Feature De-correlation Graph Collaborative Filtering for Recommendations
Collaborative filtering methods based on graph neural networks (GNNs) have witnessed significant success in recommender systems (RS), capitalizing on their ability to capture collaborative signals within intricate user-item relationships via message-passing mechanisms. However, these GNN-based RS inadvertently introduce excess linear correlation between user and item embeddings, contradicting the goal of providing personalized recommendations. While existing research predominantly ascribes this…

Net-zero vertical farm aims to solve a growing berry problem
Canadian researchers have embarked on a mission to produce year-round berry crops pretty much anywhere. The Agrotunnel vertical farm provides optimum growing conditions monitored by AI, and meets electricity needs with proprietary solar panels.

Trustless Audits without Revealing Data or Models
There is an increasing conflict between business incentives to hide models and data as trade secrets, and the societal need for algorithmic transparency. For example, a rightsholder wishing to know whether their copyrighted works have been used during training must convince the model provider to allow a third party to audit the model and data. Finding a mutually agreeable third party is difficult, and the associated costs often make this approach impractical. In this work, we show that it is …

Thermal Conductivity of Double Polymorph Ga2O3 Structures
Recently discovered double gamma/beta (γ/\b{eta}) polymorph Ga2O3 structures constitute a class of novel materials providing an option to modulate functional properties across interfaces without changing chemical compositions of materials, in contrast to that in conventional heterostructures. In this work, for the first time, we investigate thermal transport in such homo-interface structures as an example of their physical properties. Specifically, the cross-plane thermal conductivity (k) was …

A robust and tunable Luttinger liquid in correlated edge of transition-metal second-order topological insulator Ta$_2$Pd$_3$Te$_5$
The interplay between topology and interaction always plays an important role in condensed matter physics and induces many exotic quantum phases, while rare transition metal layered material (TMLM) has been proved to possess both. Here we report a TMLM Ta$_2$Pd$_3$Te$_5$ has the two-dimensional second-order topology (also a quadrupole topological insulator) with correlated edge states - Luttinger liquid. It is ascribed to the unconventional nature of the mismatch between charge- and atomic- cen…

On systems of fractional nonlinear partial differential equations
The work considers a system of fractional order partial differential equations. The existence and uniqueness theorems for the classical solution of initial-boundary value problems are proved in two cases: 1) the right-hand side of the equation does not depend on the solution of the problem and 2) it depends on the solution, but at the same time satisfies the classical Lipschitz condition with respect to this variable and an additional condition which guarantees a global existence of the solutio…

An extension operator for manifold-valued Sobolev maps on perforated domains
Motivated by manifold-constrained homogenization problems, we construct a scale-independent extension operator for Sobolev functions defined on a perforated domain and taking values in a compact connected Riemannian manifold without boundary. The proof carefully combines the prominent extension result by Acerbi et al., with a retraction argument which heavily relies on the topological structure of the manifold itself. With the aim of providing necessary conditions for the extendability of Sobol…
