Spaces of multiplier $ \sigma $-convergent vector valued sequences and uniform $ \sigma $-summability

open access: yesAIMS Mathematics
This study focuses on the development of novel vector-valued sequence spaces whose elements are characterized by constructing (weakly) multiplier $ \sigma $-convergent series. To achieve this, the concept of invariant means is rigorously examined and utilized as a foundational tool.

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

open access: yesAdvanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

Embedded Direct Ink Writing of Thermoset and Elastomeric Polymers via Frontal Polymerization

open access: yesAdvanced Functional Materials, EarlyView.
Embedded frontal polymerization direct ink writing (FP‐DIW) combines frontal ring‐opening metathesis polymerization with embedded 3D printing to decouple deposition from curing. A yield‐stress support bath stabilizes low‐viscosity inks, while on‐demand thermal initiation enables controlled front propagation. This approach expands the accessible feature

STUDY OF MACROECONOMIC INDICATORS DEVELOPMENT TRENGS OF THE KYRGYZ REGIONS USING BETA AND SIGMA CONVERGENCE

open access: yesVeredas do Direito
The purpose of this paper is to study the convergence of regions in the Kyrgyz Republic based on wages and gross regional income per capita to calculate regional inequality dynamics and forecast the period of regional development convergence. Two main approaches are used in economics to study regional development trends: beta and sigma convergence ...

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

open access: yesAdvanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Structure‐Guided Balancing of Ambipolar Transport Enables Symmetric Switching in Heterojunction Bilayer Organic Transistor Inverters

open access: yesAdvanced Functional Materials, EarlyView.
Balancing the spatially separated p‐ and n‐type transport pathways in heterojunction‐bilayer OTFTs enables symmetric inverter switching (VM ≈ 0.5VDD), whereas discrete integration of unipolar OTFTs gives polarity‐dependent and resistive responses. ABSTRACT High inverter performance in ambipolar organic electronics requires balanced channel strengths ...
