Исследование устаревания настройки RIS в сценариях с мобильными устройствами
Информационные процессы. 2024. Т. 24. № 3. С. 300–311.
Reconfigurable Intelligent Surface (RIS) is a promising technology that can improve the throughput and coverage of wireless networks. The effectiveness of RIS depends on its configuration, which is adjusted taking into account the position of transmitting and receiving devices in space. Over time, the RIS configuration becomes outdated due to changing environmental conditions caused by the movement of devices and other objects. This paper examines the aging of the RIS configuration obtained by focusing or redirecting the reflected beam in a system with mobile devices. The paper shows that the difference in the required reconfiguration time to compensate for aging can reach hundreds of milliseconds for redirection and focusing. The limitations of existing analytical expressions for the required reconfiguration time are demonstrated.

Acute ischemic stroke (AIS) analysis from two-dimensional (2D) clinical imaging is hindered by uncontrolled slice tilt and geometric inconsistencies that violate the assumptions of pose-agnostic deep learning (DL) models. This paper proposes a unified geometry-aware, frequency-domain framework for tilted slice localization and ischemic stroke segmentation that explicitly decouples pose estimation from lesion analysis. The method ...

The cardinality-constrained Markowitz problem is NP-hard and traditionally solved with commercial MIQP solvers. Following the 2022 export restrictions that rendered both commercial MIQP software and cloud quantum platforms (IBM Quantum, D-Wave Leap) inaccessible from the Russian Federation, practitioners require open-source alternatives. This paper systematically compares three solver families for the discrete mean-variance problem: two open-source ...

Background/Objectives: Synolitic graphs (SGs) were developed for task-based fMRI, where
edge weights encode the discriminative power of pairwise regional features; whether similar
information can be recovered from resting-state data was untested. We benchmarked
SGs for autism spectrum disorder (ASD) classification using the multisite ABIDE-I dataset
(871 subjects: 403 subjects with ASD, 468 typical controls; 17 sites; CC200 atlas). Methods:
Using ...

Electronic health records (EHRs) contain vast volumes of clinical information that encode complex relationships between diseases. Traditional approaches to the analysis of interrelated or co-occurring diseases have focused on pairwise associations between diagnoses, missing the higher-order structures that characterise multimorbid patients. The present paper offers a narrative review of existing statistical, machine-learning, and artificial intelligence ...

Psychological characteristic estimation from multimodal in-the-wild behavior is usually studied using separate corpora, each annotated for a single target task. Such annotation fragmentation limits cross-task learning and cross-domain generalization across affective, dispositional, and interactional phenomena. To address this problem, we use emotion, apparent personality trait, and ambivalence recognition as representative tasks and introduce MM-PSYCHE, a ...

Hypergraphs provide a natural framework for representing neurophysiological interactions distributed across sets of sensors. A key methodological question is how hyperedges should be defined from frequency-resolved electroencephalography/magnetoencephalography (EEG/MEG) data. We demonstrate a construction strategy in which hyperedges are obtained from canonical coherence (caCOH), an extension of coherence that estimates coupling between multidimensional signal spaces. To ...

Identification of coherent states of spiking neural networks is a fundamental problem of
synchronization theory but conventional methods are computationally expensive. We apply
the crystallographic ideas of processing periodic structures to the analysis of various
states of spiking neuronal networks. In particular, the introduced approach is based on
the application of two-dimensional Fourier transform to rasterplots. By the position ...

The integration of data-driven and knowledge-driven approaches in generative geospatial modelling (GGM) is often hindered by their mathematical incompatibilities. Here, we propose a geometric algebra (GA)-based framework that employs a unified multi-vector representation to fuse heterogeneous data and diverse knowledge. The framework facilitates structured reasoning and hypothesis generation through a task-adaptable, five-stage cycle: representation, reasoning, ...

EEG recordings are often affected by the loss or corruption of individual channels due to electrode detachment, poor scalp contact, or external interference. Such channels must be accurately reconstructed before further analysis. In this study, we investigate Next-Generation Reservoir Computing (NG-RC) as a data-driven approach for reconstructing corrupted EEG channels and compare its performance with ...

Реконфигурируемая интеллектуальная поверхность (РИП) представляет собой одну из перспективных технологий для повышения пропускной способности и расширения покрытия существующих и будущих беспроводных сетей. Предполагается, что РИП будет активно применяться в сценариях вне помещений, где она будет подвержена влиянию погодных условий, таких как дождь. Дождь, в свою очередь, повлияет на амплитудно- и фазо-частотные характеристики элементарных ячеек (ЭЯ), ...

Реконфигурируемые интеллектуальные поверхности (англ.: Reconfigurable Intelligent Surface, RIS) обладают значительным потенциалом для повышения эффективности беспроводных сетей. Несмотря на их значительную привлекательность в исследовательской сфере, существует заметный пробел: отсутствие адаптируемой модели канала, которая облегчает изучение производительности систем беспроводной связи с использованием однобитных RIS в сложных сценариях. В работе исследуется производительность системы с RIS при использовании модели ...
