Adaptive mixing formation control of multiquadrotor unmanned aerial vehicle systems
Abstract This paper presents a distributed adaptive mixing control (AMC) design for formation maintenance of systems of multiquadrotor UAVs (q‐UAVs) during commanded path‐tracking maneuvers. The proposed formation control scheme has a two‐level structure. The high level defines the desired trajectories for rigid and persistent formation acquisition and

Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine
Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

Paphiopedilum purpuratum Mediates Adaptation via a Dual‐Fungal Strategy: Confronting a physiological trade‐off (↑seed set vs. ↓photosynthesis), Paphiopedilum purpuratum restructures its root microbiome. Mycorrhizal fungi stabilize into a resilient core network, whereas non‐mycorrhizal fungi shift to a dynamic beneficial periphery.

ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

Too Hot to Profit? Climatic Stress and Farm‐Level Performance in Italian Viticulture
ABSTRACT This paper investigates the economic impact of long‐run climatic conditions on Italian wine farms by applying a Ricardian framework to 1431 firms from the 2022 RICA‐FADN survey. We combine farm‐level revenues with viticulture‐specific agroclimatic indicators to assess how climate stress shapes profitability across 77 Italian NUTS3 provinces ...

ABSTRACT Background There is an increasing interest in healthier, nutrient‐rich foods so alternative grains produced in smaller quantities—including spelt wheat (Triticum spelta L.)—have once again become the focus of consumers. At the same time, the scientific proof of these claims is incomplete.
