Operational Technology (OT) is experiencing one of the most remarkable shifts in its history as increased OT and Information Technology (IT) systems converge to form unified, intelligent systems. The aim of this review article is to look at the most important technology trends that are currently changing the OT landscape and consider the impact of these on architecture, operation, and security fo…

6G paradigm enables massive network slicing for pervasive digitization across vertical industries, demanding scalable,sustainable, AI-driven zero-touch automation, particularly under non-IID conditions in live networks. This work introducesa cloud-native service-level agreement (SLA)-driven stochastic policy to guarantee a scalable and fast operation of constrainedfederated learning (FL)-based an…

With the increasing deployment of Reinforcement Learning (RL) for network optimization at the edge of wirelessnetworks, the RL workload emerges as a significant challenge. While the placement of general Machine Learning workloadsacross the cloud–edge continuum has been widely studied, existing solutions typically exclude RL techniques due to theirdistinct structure and operational requirements. I…

Sixth-generation (6G) wireless networks are expected to meet all the demands of the next decade, a feasibility that is onlypossible with advances in network design and management. This paper first proposes a unified resource management framework for a 6G-based network architecture that includes an Open Radio Access Network (O-RAN) deployment and then defines a hierarchical network energy control …

We analyze the linearized dynamics of the validated late-time coherence-field kernel of Radial Coherential Dynamics (RCD), the bistable Allen–Cahn / Wright–Fisher reaction–diffusion equation whose coarsening behavior in expanding Friedmann–Robertson–Walker (FRW) backgrounds was established in prior work [1]. Computing the principal symbol of the operator governing small perturbations δC about a h…

This technical note is Part I-2 of the AIKernel / AIOS Phase-1 specification series. It defines the VFS Architecture and Semantic Storage Model as the storage boundary governance layer for deterministic AI systems. The paper introduces capability-based VFS sessions, non-routable transition semantics, bounded storage topology, and deterministic read-only projection for replay. It formalizes storag…

Age of Information (AoI) is a widely used metric to quantify the freshness of updates in communication systems. Existing AoI analyses implicitly assume a shared or synchronized notion of time between transmitter and receiver, thereby neglecting distortions arising from relative motion and gravitational effects. In this paper, we investigate the impact of relativistic time dilation on information …

This paper is the STC “product-integral” layer: we define and analyze the σ-chronological exponential (time-ordered exponential) for BV clocks σ with atoms and flats, in a form that respects the frozen STC semantics. In the kernel regime dσ = w(t) dt + P k αkδtk with locally finite atoms, we build a propagator by interleaving (i) the continuous ordered exponential driven by w(t) dt and (ii) expli…

Service virtualization (SV) enables testing teams to simulate unavailable or unstable dependencies, but enterprise deployments suffer from linear scaling costs, metadata fragmentation in siloed binary artifacts, and high tooling friction. This paper presents a longitudinal industrial case study of a Unified SV Control Plane deployed since 2017 at a large financial services organization. The archi…
