PID‐Like Robust Control of Non‐Minimum Phase Robotic Manipulators
ABSTRACT This paper proposes an output‐feedback tracking controller for non‐minimum phase nonlinear systems with unknown uncertainties and external disturbances, where not all states are measurable, and the zero dynamics are unstable. The approach combines a backstepping‐based stabilizing state‐feedback law with a cascade extended high‐gain observer ...

A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats
ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...

The Chatter Vibration of Lathe Tool
The primary chatter and regenerative chatter of the turning tools are treated in this paper. I have obtained the stability condition of the reduced equation of motion of the turning tools. The regenerative chatter may be said to consist of the forced and the self-excited vibrations.

Host‐Specific Vocal Similarity in Fledgling Levaillant's Cuckoos and Babblers in West Africa
Young cuckoos can mimic host calls to gain care, but the extent of this similarity varies across hosts. Analysing fledgling begging calls across four host associations, we found that calls given during food transfer were broadly similar and did not match host calls, whereas cuckoos reared by their main West African host closely mimicked host begging ...

Reinventing henna: Enzyme‐catalysed colour release from stabilized Lawsonia inermis L. extracts
The instability and reduced dyeing performance of a cosmetic formulation containing 2‐hydroxy‐1,4‐naphthoquinone (lawsone), derived from Lawsonia inermis L., is demonstrated in comparison to a novel two‐component system. This system comprises one formulation with naturally occurring lawsone precursors and a second containing a specific hydrolase ...

Modelling and Simulation of a New Variable Stiffness Holder for Milling of Flexible Details
Modern industry expectations in terms of milling operations often demand the milling of the flexible details by using slender ball-end tools. This is a difficult task because of possible vibration occurrence. Due to existence of certain conditions (small

This study combines theoretical and experimental approaches to systematically link plasma dynamics with reaction engineering. A novel reactor design with laminar gas flow and magnetically induced nonthermal plasma rotation enables precise determination of residence times and effective plasma volumes.

Noise, Vibration, and Harshness (NVH) Challenges in Hydrogen Internal Combustion Engine Vehicles
ABSTRACT This paper presents a state‐of‐the‐art literature review on noise, vibration, and harshness (NVH) in hydrogen‐fuelled internal combustion engines. Studies published between 2011 and 2025 were screened, covering fundamental flame physics, test‐bench work, and recent prototype vehicles.

Design of Chatter-Resistant Damped Boring Bars Using a Receptance Coupling Approach
Deep hole boring using slender bars that have tuned mass dampers integrated within them make the boring process chatter vibration resistant. Dampers are usually designed using classical analytical solutions that presume the (un)damped boring bar which ...

Abstract This paper explores how ‘what matters’ can surface in multisensory arts‐informed projects as ways for young people to survive and stay with gender and sexuality troubles that are always more than theirs. Situated in an ex‐mining post‐industrial locale, we make an agential cut in a longitudinal research and engagement project called Unboxing ...
