In this paper methodology of conceptual design of airborne radar with synthetic aperture antenna (SAR) in the framework of mathematical technology paradigm is under investigation, moreover main attention is paid to physical but not phenomenological models. Performance criterions of design for SAR as a whole system and for its subsystems have been introduced. Approximation of specific effective dispersion section matrix on remote sensing data by means of two-dimensional atomic interpolants, two-dimensional atomic Kravchenko wavelets and two-dimensional generalized Kotelnikov theorem with vector-parametric atomic functions is considered. On the basis of the theory of growing interfaces and the classical problem on diffraction of plane electromagnetic wave by wedge exactly solved models of electrodynamic properties of surfaces in cold regions of the Earth are constructed.

AIVBVI semiconductors, particularly lead chalcogenides, remain key materials for mid-wave infrared (MWIR) photodetection due to their narrow bandgap and exceptional carrier transport properties. However, the realization of high-quality p-type PbTe thin films, suitable for p–n junction devices, remains a technological challenge. In this work, we report the fabrication of high-mobility p-type PbTe thin films grown on ...

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 ...

Pyramidal solitons (solitons with more than two inflection points) of the generalized Korteweg–de Vries (KdV) equation are investigated. Necessary and sufficient conditions for the existence of such structures are presented. Within the framework of the generalized Gardner equation — the simplest model that admits pyramidal solitons as solutions — it is shown that these solutions ...

Reaching lasing in electrically pumped microdevices based on solution-processed
semiconductors poses a substantial scientific and technological challenge. Halide
perovskites offer a promising platform for electrical injection1, as their optically
excited single-crystal cavities2–4 and predesigned5,6 or postprocessed microstructures7,8
have exhibited low lasing threshold. Indirect electrical pumping of a dual-cavity
perovskite laser was recently obtained9, using a well-established technological
concept of embedding a ...

Open access to images creates opportunities for violation of the authors' rights. Digital watermarks can be used to securely publish images online. They are invisibly added into the images before publication and can be extracted at any time to verify ownership. However, achieving a balance between embedding imperceptibility and robustness to image processing operations is ...

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 ...

The electric double layer (EDL) at a single-crystal metal surface is controlled not only by the electrolyte composition and the electrode potential, but also by the atomic structure of the surface itself. This makes the Ag(hkl)/NaF interface a stringent test for continuum theories of the EDL. In the third part of our series, we examine ...

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 ...
