Dog Breed Classification Using Part Localization [PDF]

, 2012
We propose a novel approach to fine-grained image classification in which instances from different classes share common parts but have wide variation in shape and appearance. We use dog breed identification as a test case to show that extracting corresponding parts improves classification performance.

Stoma‐Shell Nanoarchitecture for Enhanced Plasma Confinement Catalysis in Synthesis of Ethanol from CO2

Advanced Functional Materials, EarlyView.
High‐energy electron impact in plasma catalysis often causes excessive dissociation of active intermediates, limiting C2+ product selectivity. To address this challenge, a bio‐inspired stoma‐shell nanoarchitecture is designed to decouple electron impact from catalytic reaction zones.

Testicular growth and comb and wattles development in three Italian chicken genotypes reared under free range conditions [PDF]

, 2015
Male chickens belonging to three Italian purebreds \u2013 Ermellinata di Rovigo (ER), Robusta lionata (RL) and Robusta maculata (RM) \u2013 were studied. All the birds were reared under the same rearing conditions (from May until autumn).

Shaping of Biohybrid Functional Living Materials

Advanced Functional Materials, EarlyView.
This work demonstrates a strategy for shaping living mycelium into functional materials by directing its natural growth. Nanoparticles armor hyphae, micron‐scale particles entangle within the network, and printed hydrogel architectures steer expansion, creating defined geometries.

Bioactive Conductive Ti3C2Tx‐Ce Hydrogel Facilitates Spinal Cord Injury Repair Through ROS Scavenging and Mitochondrial Regulation

Advanced Functional Materials, EarlyView.
Bioactive conductive Ti3C2Tx‐Ce hydrogels with with scavenging ROS and alleviating neuronal mitochondrial dysfunction are exploited for SCI treatment. This functionality is attributed to interfacial activation modification of Ti3C2Tx with Ce3+ ions to in‐situ form Ce(OH)x‐mediated protective layer, which is beneficial to enabling stable intracellular ...

Characterization of an Injectable Poly(vinyl alcohol)‐gelatin Hydrogel for Growth Factor Delivery in an Orthopedic Application

Advanced Healthcare Materials, EarlyView.
This work introduces photo‐crosslinkable tyraminated poly(vinyl alcohol)‐gelatin (PVA‐GT) hydrogels as tunable injectable platforms for tissue engineering and growth factor delivery applications. This schematic illustrates the two developed hydrogel formulations and the experimental workflow used to evaluate their physico‐chemical properties in vitro ...

Morphological characterization and breeding system identification of local sheep breeds in Niger [PDF]

Advances in Animal Biosciences, 2010
In Niger, livestock breeding is the second rural population activity, contributing 12% to the national GDP and 40% to agricultural production. The national livestock include a large range of domestic animal species among which ovine species, which represent 20% of this livestock.

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement

Advanced Materials Interfaces, EarlyView.
ABSTRACT Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination
