ORIX: Orchestration of RIS with xApps for Smart Wireless Factory Environments
Announce Type: replace-cross Abstract: The vision of a smart wireless factory (SWF) demands highly flexible, low-latency, and reliable connectivity that goes beyond conventional wireless solutions. Reconfigurable intelligent surface (RIS)-empowered communications, when integrated with the open radio access network (O-RAN) architectures, have emerged as a promising enabler to meet these challenging requirements. This article introduces the methodology for the orchestration of RIS with xApps...
Deconstructing the Composite Channel for Beyond Diagonal RIS: Channel Estimation and Beamforming Design
arXiv:2606.01564v1 Announce Type: cross Abstract: As beyond-diagonal reconfigurable intelligent surfaces (BD-RISs) gain increasing attention in high-frequency wireless communications, accurate and scalable channel-estimation methods become essential. This paper develops a parametric channel-estimation and beamforming framework that deconstructs the composite BD-RIS channel into its generating directional factors, revealing the tensor structure induced jointly by propagation geometry and...
Encoded Jamming Secure Communication for RIS-Assisted Systems
Announce Type: replace Abstract: This paper investigates a cooperative jamming (CJ)-aided secure wireless communication system. Conventional CJ schemes transmit Gaussian noise (GN) to improve security, which inherently degrades the legitimate receiver's performance. While encoded jamming (EJ) mitigates this interference, its superiority over GN is highly channel-dependent.
Mutual Information Optimization via K-Recursion and Automatic Differentiation for Linear Gaussian Wireless Networks
new Abstract: We present a differentiable framework for end-to-end mutual information (MI) optimization over linear Gaussian directed acyclic graphs (DAGs). The framework targets network-wide design under global constraints, such as a total transmit power budget, and covers MIMO precoding, amplify-and-forward relays, RIS-aided channels, and branching/merging topologies within a common linear Gaussian model. Its core ingredient is a \emph{K-recursion} that analytically propagates all...
Microwave Linear Analog Computer (MiLAC) for Simultaneous Active and Passive Beamforming
arXiv:2605.31549v1 Announce Type: new Abstract: Microwave linear analog computers (MiLACs) have recently emerged to enable high-performance and efficient beamforming in the analog domain. In this paper, we introduce a dual-functionality framework for MiLAC-aided transceivers. Beyond analog-domain precoding/combining (active beamforming), a MiLAC and its antenna array can simultaneously act as a reconfigurable intelligent surface (RIS) (passive beamforming).
Weighted Sum-Rate Enhancement for Flexible Intelligent Metasurface-Assisted Multicell Systems
arXiv:2606.06845v1 Announce Type: new Abstract: Flexible intelligent metasurface (FIM) technology has emerged as a promising technology for enhancing wireless communication performance by dynamically reshaping the propagation environment. Compared with conventional rigid reconfigurable intelligent surfaces (RIS), an FIM is composed of multiple electromagnetic (EM) scattering units, each of which can flexibly modify its displacement in the direction normal to the surface, thereby...
The Dark Regulome: Disentangling Predictability from Regulation in Genomic Foundation Models
Announce Type: new Abstract: High-grade gliomas integrate into neural circuits through functional synapses with neurons, raising the question of which noncoding elements shape synaptogenic gene expression in tumor cells. The regulatory program written across the dark genome, what we call the $\textit{dark regulome}$, is the natural substrate to probe, and sequence foundation models offer a zero-shot route through in-silico mutagenesis (ISM); yet likelihood-based scoring is tautologically...
UK's GSK to acquire U.S. drugmaker Nuvalent for $10.6 billion as pharma giants race to expand pipelines
U.K. pharmaceutical group GSK has entered an agreement to acquire U.S.-based drugmaker Nuvalent for $10.6 billion to bolster its lung cancer pipeline, in what would be the British drugmaker's largest acquisition in more than a decade. The all-cash deal values Nuvalent at about $124 per share, according to a GSK filing on Tuesday, representing a 40% premium to its last closing price. The Financial Times had reported the transaction earlier on Tuesday.
