The greedy basis equals the theta basis

open access: yes, 2015
We prove the equality of two canonical bases of a rank 2 cluster algebra, the greedy basis of Lee-Li-Zelevinsky and the theta basis of Gross-Hacking-Keel-Kontsevich.Comment: 17 ...

Genetic variation of keel and long bone skeletal properties for 5 lines of laying hens

open access: yesJournal of Applied Poultry Research, 2020
Summary: Fractures to the keel bone is one of the greatest problems facing the laying hen industry. With most severe effects observed in non-cage housing, frequencies are expected to dramatically increase as the industry continues transitioning away from

Bridging Nature and Technology: A Perspective on Role of Machine Learning in Bioinspired Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Machine learning (ML) is revolutionizing the development of bioinspired ceramics. This article investigates how ML can be used to design new ceramic materials with exceptional performance, inspired by the structures found in nature. The research highlights how ML can predict material properties, optimize designs, and create advanced models to unlock a ...

Early Onset of Laying and Bumblefoot Favor Keel Bone Fractures

open access: yesAnimals, 2015
Numerous studies have demonstrated influences of hybrid, feed, and housing on prevalence of keel bone fractures, but influences of behavior and production on an individual level are less known.

Dislocation‐Mediated Thermoelectric Performance and Mechanical Behavior

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations can scatter phonons to reduce thermal conductivity, thereby enhance thermoelectric performance. However, dislocations also impact mechanical properties, leading to increased brittleness and altered plasticity. It is essential to clarify the complex relationship between dislocations, thermal transport, and mechanical stability to achieve a ...

A risk assessment of health, production, and resource occupancy for 4 laying hen strains across the lay cycle in a commercial-style aviary system

open access: yesPoultry Science, 2020
Different strains of commercial laying hens have been molded by varying selection pressures, impacting their production, health, and behavior. Therefore, assumptions that all laying hen strains use the given resources within aviary systems similarly and ...

Keele Cataclysmic Commentary [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
What kind of person is invited to make Conference summaries? For conference introductions it’s easy — you just invite some past, long-retired Directorsaurus Rex to make a few deathbed corrections to his memories of how he founded the field and anticipated all future developments.

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow

open access: yesAdvanced Functional Materials, EarlyView.
Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.
