Hardware- and User-Induced Micromobility Effects in In-Door Radio Access at 140 GHz
St. Petersburg Polytechnical University Journal: Physics and Mathematics. 2023. Vol. 16. No. 3.2. P. 411–416.
Sub-terahertz frequency band is beneficial for radio access networks of the sixth generation. Due to rather limited power capacity, there appears a necessity to equip transmitters and receivers in sub-terahertz wireless channels with high directivity antennas. This, however, leads to a potential connection failure in response to even a minor linear or angular displacement of a user equipment. This article is focused on a hardware- and user-induced micromobility effects for different scenarios of in-door radio access at carrier frequency of 140 GHz. The developed measurement setup enables fast simultaneous logging of linear and angular displacements of a user equipment with respect to radio access point and the corresponding received signal strength. Experimental data is processed by Allan variance analysis, statistics is acquired for a large number of samples. We believe that our findings should be of use in the development of beam steering solutions for reliable sub-terahertz wireless communications.

Large language models (LLMs) show promise for clinical decision support, but privacy constraints and unreliable free-text decisions limit deployment. We present Medotor, a locally deployed system for screening patients with chronic rhinosinusitis with nasal polyps (CRSwNP) for biologic therapy, and evaluate prompt design on 163 retrospective cases (132 eligible and 31 ineligible). Five models were ...

Equilibration is often assumed rather than tested in molecular dynamics studies of confined liquid–liquid interfaces, even though different physical properties may relax on different time scales. In this work, equilibration is examined using an automated truncation method based on the marginal standard error rule. Interfacial geometry, wetting behaviour, and density-related properties are analysed for liquid–liquid ...

Previously, it has been effectively shown that nuclear quantum effects (NQE) considerably influence the prediction of the warm dense hydrogen phase diagram. Here, we study the influence of NQE on the parameters of the conducting state formation in warm dense hydrogen using path integral molecular dynamics (PIMD) within the framework of the finite temperature density ...

Abstract
Automated interpretation of magnetic flux leakage (MFL) data is central to condition assessment of long-distance oil and gas pipelines. Yet, full-resolution panoramas are difficult to process without either suppressing small anomalies through resizing or fragmenting elongated objects at sliding-window boundaries. We propose MFL-ScrollNet, a recurrent sliding-window detector that formulates panoramic analysis as an ordered sequence ...

The key principle of the operation of an unmanned aerial vehicle is the
continuous collection and processing of data from on-board sensors, controlled by a
real-time operating system (RTOS). For multicopters, where the minimum delay in
the system’s response to changes in flight is critically important, the main factor is the
performance of the flight controller’s computing core. Historically, ...

Efficient management of the Key-Value (KV) cache is essential for deploying large language models (LLMs) in long-context scenarios, where memory requirements often exceed the capacity of resource-constrained hardware. Many existing training-free compression algorithms typically rely on attention-driven heuristics, but exhibit two key limitations. First, they require explicit attention score computation, which is difficult to reconcile ...
