Sliding Mode Control and Observation for Upper Limb Robotics Rehabilitation

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Stroke is a leading cause of upper limb motor impairments, which often require rehabilitation. General purpose robotic manipulators enable effective therapy through exercises such as Center Out Point‐to‐Point (CO‐PTP) and Teach‐and‐Track (TT), which respectively demand accurate estimation and rejection of the interaction force exerted by the ...

Formation Control With Obstacle Avoidance of Underwater Swarms Based on Relative Visual Feedback

Journal of Field Robotics, EarlyView.
ABSTRACT Underwater multi‐robot and swarm systems require advanced methodologies for controlling collective behavior. Conventional single‐robot techniques, such as tethering, sonar imaging, and acoustic localization, are not scalable or effective for swarm applications.

Integrated assessment of meteorological drought impacts on terrestrial water storage and vegetation dynamics in East Africa

River, EarlyView.
Abstract Water is essential for life, and effective hydrological management is crucial for economic stability and quality of life. Poor water resource governance can lead to scarcity, displacement, or even fatal consequences. Hydrological conditions in East Africa are influenced by drivers such as demographic expansion, industrialization, droughts, and

The influence of secondary reinforcement on a strut‐and‐tie model for the design of reinforced concrete corbels

Structural Concrete, EarlyView.
Abstract In precast concrete structures, optimizing the design of corbels by considering the contributions of secondary reinforcement elements can significantly improve construction economy, especially when corbels are repeated multiple times. This paper proposes a strut‐and‐tie model for reinforced concrete corbels subjected to vertical and/or ...

Closed‐form solutions for dynamic punching shear assessment in flat slabs subjected to sudden column removal

Structural Concrete, EarlyView.
Abstract Simplified closed‐form equations are commonly used in structural design to prevent punching shear failures of concrete flat slabs supported on columns in permanent and transient situations, whereas more advanced methods are generally used in verifications at accidental design situations due to the lack of suitable equivalent approaches ...

Repeat SPAC Sponsors

European Financial Management, EarlyView.
ABSTRACT Sponsors are the key value‐generating resource for special purpose acquisition companies (SPACs). We identify a subgroup of sponsors—repeat sponsors—who have formed and managed multiple SPACs. Repeat sponsors identify target companies faster, and their SPACs merge with private companies of higher quality. However, these benefits are attenuated

Combining eDNA metabarcoding and stable isotope analysis advances diet studies in a colonial, non‐regurgitating seabird

Ibis, EarlyView.
Understanding seabird diet is fundamental to assessing trophic interactions and predicting responses to environmental change. However, seabird diet studies are often constrained by low taxonomic resolution, invasive sampling methods or reliance on opportunistically collected samples, leaving the diet of important populations such as Common Guillemots ...

Sorption Isotherm Curves in Dry Extruded Pet Foods: Evaluation and Comparison With the Drying Curve

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Sorption isotherms evaluate water exchange between food and environments with different water activities (aw), providing valuable information on physical changes and susceptibility of deterioration due to lipid oxidation and microbial growth.

Reading Dürer in Late Sixteenth‐Century Padua: Matteo Macigni (ca. 1510–1582), His Library and the Annotated Institutionum geometricarum (Paris, 1535)

Renaissance Studies, EarlyView.
ABSTRACT This article contributes to the history of material culture and intellectual biography by definitively identifying the Paduan scholar Matteo Macigni (ca. 1510–1582) as the author of the annotations found in a 1535 copy of Albrecht Dürer’s Institutionum geometricarum currently preserved in Vicenza.

Adenine nucleotide translocator and ATP synthase cooperate in mediating the mitochondrial permeability transition

The Journal of Physiology, EarlyView.
Abstract figure legend Both ATP synthase and adenine nucleotide translocator (ANT) play key roles in mediating the permeability transition. The contribution of ANT becomes evident in the presence of atractylate (ATR) at pH 6.5, a condition that prevents ATP synthase channel activity. At pH 7.4, this effect is minimal, suggesting a critical role for ATP
