HF Heating Effects as Seen From Below and Above: First Results of Joint SURA–Ionosfera‐M Experiment

Abstract This paper presents the first results of a coordinated experiment on the ionospheric plasma response to high‐frequency (HF) overdense heating, conducted using the SURA heating facility and the Ionosfera‐M satellite. The experiment combined ground‐based observations with...

Negative Spectrum of Non-local Operators with Periodic Potential

The paper deals with spectral analysis of non-local operators arising in population dynamics models. We consider negative periodic perturbations of non-local operators of the convolution type. Such operators describe evolutions of the first correlation function in the stochastic...

Earliest simultaneous multi-color optical observations of GRB 230328B: from 41 seconds to the host-galaxy identification

Abstract We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt γ-ray observations with exceptionally early simultaneous optical photometry and extensive X-ray, radio, and host-galaxy follow-up. NUTTELA-TAO began simultaneous g′r′i′...

Founder Narcissistic Admiration and Young Firm Performance: The Mediating Role of Innovative Ambidexterity

Abstract Personality characteristics of entrepreneurial leaders appear to play an important role in facilitating the kinds of innovative activities that enhance young firm performance. Scholars have highlighted the need for these firms to demonstrate innovative ambidexterity, or...

Peptide language pragmatic analysis and two-stage hierarchical learning framework for therapeutic peptide prediction

Therapeutic peptides exert pivotal effects in diverse biological processes, and have attracted significant interest in the field of biomedicine in recent years. However, most existing methods often fail to adequately capture the intricate interactions among amino acid residues an...

Generative geospatial modelling with geometric algebra

Abstract 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...

Fiscal and Structural Drivers of Regional Investments Divergence: Evidence from Kazakhstan and European Benchmark Economies

This study investigates whether the interaction between structural characteristics and fiscal mechanisms determines regional investment allocation and contributes to regional divergence in Kazakhstan. To achieve this aim, panel regression with interaction effects and cross-countr...

Correlated insulator Moiré bolometer

Light incident on an insulator is generally not expected to turn it into a metal without invoking intense ultrafast excitation that leads to transient structural transitions. Here we show that magic-angle twisted bilayer graphene tuned to half filling of the moiré band provides a...

From stigma to substitution: a qualitative study on consumer reevaluation of the “Made in China” label in a disrupted automobile market

Purpose This study aims to explore how consumers reevaluate deeply integrated country-of-origin (COO) stigmas in the context of market disruption. The authors aim to examine consumers’ perceptions of “Made in China” and highlight the legitimation mechanisms they use to navigate t...

Insulin-Like Growth Factor 2 Modulates Macrophage Polarization: the Role of the IGF2–IGFBP6 Axis

Triple-negative breast cancer (TNBC) is characterized by an aggressive clinical course and extremely limited targeted therapy options. One of the key drivers of immunosuppression in the tumor microenvironment is the polarization of tumor-associated macrophages (TAMs) towards the...
