Bioinspired Adaptive Leg‐Claw Enables Robust Perching and Grasping for UAVs

open access: yesAdvanced Science, EarlyView.
Inspired by owl limb morphology and bat roosting behavior, this study presents a bioinspired adaptive leg‐claw mechanism that enables UAVs to perform robust and versatile perching and grasping. The design integrates a four‐link tibial structure, tension‐driven deformable feet, and active control, enabling stable perching on various branches and ...

Genetic editing for improvement of fruit and small fruit crops

open access: yesHorticulture and viticulture, 2019
Today the range of crops, which are studied and improved with the help of genetic editing technologies, in particular with CRISPR/Cas system, is actively expanding. High accuracy, ease of editing tools application and relative cheapness allow the use of this method in research in various fi elds of biology.

SUPERMARKETS AND CONSUMERS IN AFRICA: THE CASE OF NAIROBI, KENYA [PDF]

open access: yes
Supermarkets are rapidly penetrating urban food retail in Kenya and spreading well beyond their initial tiny market niche into the food markets of lower-income groups. Having penetrated processed and staple food markets much earlier and faster than fresh

MS imaging of small metabolites in fruits [PDF]

open access: yes, 2012
MS Imaging of large molecules, e.g. proteins and lipids, have been reported with MALDI. On the other hand, few works have been done on mapping the small molecules by MALDI imaging.

Tetrahedral DNA Nanostructure‐Based Biomimetic Nanovesicles Attenuate Sepsis‐Associated ARDS by Suppressing Glycolysis via the BMAL1/PFKFB3 Axis

open access: yesAdvanced Science, EarlyView.
Upon inhalation, RM@TNT could persist long‐term in the diseased lungs, while undergoing disintegration to release TNT specifically within the ROS‐rich pathological microenvironments of SA‐ARDS. The released TNT was then precisely delivered to AMs via Tuftsin, where it released Nob intracellularly to activate BMAL1 expression, thus inhibiting AM ...

Critical Thickness Ratio for Buckled and Wrinkled Fruits and Vegetables

open access: yes, 2013
Fruits and vegetables are usually composed of exocarp and sarcocarp and they take a variety of shapes when they are ripe. Buckled and wrinkled fruits and vegetables are often observed. This work aims at establishing the geometrical constraint for buckled

3D‐Printed Metal‐Supported MOF‐Heteropoly Acid Nanozyme for High‐Performance Peroxidase‐Mimic Activity and Ultra‐Sensitive Glucose Detection

open access: yesAdvanced Science, EarlyView.
A hierarchically structured Fe‐BTC‐PMA immobilized 3D‐printed platform is engineered as a robust artificial enzyme for colorimetric glucose sensing. The hybrid architecture efficiently activates H2O2 to drive TMB oxidation. This integrated system enables sensitive, reusable, and scalable detection with enhanced catalytic stability and analytical ...

Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System

open access: yesAdvanced Science, EarlyView.
Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

Export Market Linkage via Gentleman's Agreement: Evidence from French Bean Marketing in Kenya [PDF]

open access: yes
"Gentleman's agreements" involving handshakes or promissory market access possibilities through brokers and middlemen have enabled most small farmers in Kenya to export an extensive array of fruits and vegetables.
