Effect of Stress-Induced Grain Growth During Room Temperature Tensile Deformation on Ductility in Nanocrystalline Metals

open access: yes, 2010
In the present study defect-free nanocrystalline (nc) Ni-Co alloys with the Co content ranging from 2.4-59.3% (wt.%) were prepared by pulse electrodeposition. X-ray diffraction analysis shows that only a single face-centred cubic solid solution is formed

Repetitive Transcranial Magnetic Stimulation of Dorsolateral Prefrontal Cortex Affects Performance of the Wisconsin Card Sorting Task during Provision of Feedback

open access: yesInternational Journal of Biomedical Imaging, 2008
Early functional neuroimaging studies of tasks evaluating executive processes, such as the Wisconsin card sorting task (WCST), only assessed trials in blocks that may contain a large amount of different cognitive processes. More recently, we showed using

MEMÓRIA DA IMAGINAÇÃO - REFLEXOS DA PQ 2019

open access: yesCena, 2020
O rosto da Quadrienal de Praga (PQ) tem mudado lentamente de um estilo de apresentação tradicional, com competições nacionais expostas em uma galeria, para um evento experimental imersivo, um festival. Mas a questão-chave e a principal missão da PQ ainda

Exploring the mismatch between the theory and application of photosynthetic quotients in aquatic ecosystems

open access: yesLimnology and Oceanography Letters, 2023
Estimates of primary productivity in aquatic ecosystems are commonly based on variation in O2, rather than CO2. The photosynthetic quotient (PQ) is used to convert primary production estimates from units of O2 to C.

Breakpoint Distance and PQ-Trees [PDF]

open access: yes, 2010
The PQ-tree is a fundamental data structure that can encode large sets of permutations. It has recently been used in comparative genomics to model ancestral genomes with some uncertainty: given a phylogeny for some species, extant genomes are represented by permutations on the leaves of the tree, and each internal node in the phylogenetic tree ...

Physics Informed Generative Surrogate Learning for Full Wave Validated Real Time Beamforming in Programmable Metasurfaces

open access: yesAdvanced Electronic Materials, EarlyView.
A physics‐guided generative surrogate framework is developed for programmable metasurface beamforming. Mode‐conditioned binary state generation, aperture‐physics prediction, routed residual correction, NSGA‐II optimization, and CST validation are combined to support fast candidate screening and full‐wave beam refinement across single‐beam, dual‐beam ...

Post-combustion CO2 capture retrofit from diesel-powered Arctic mines – Techno-economic and environmental assessment

open access: yesCarbon Capture Science & Technology
This study evaluates the economic feasibility and environmental impacts of retrofitting a diesel-based powerhouse in the Canadian Arctic with a post-combustion carbon capture process at an active gold mining site isolated from cheaper or cleaner ...

Structure de l’écoulement et de mélange dans un éjecteur supersonique gaz-gaz installé dans un système frigorifique d’une capacité de 10TR

open access: yesJournal of Materials and Engineering Structures, 2022
La complexité de l’écoulement dans un éjecteur nécessite une visualisation très poussée afin de décrire le comportement de l’éjecteur. Cet article repose sur une simulation de l’écoulement de R245fa dans l’éjecteur supersonique gaz-gaz installé dans un ...

‘CAPTCHA’ dissolves the night: Considerations on the poetics of intimate homelessness of Tarso de Melo

open access: yesTexto Poético, 2020
This article proposes a reading of the poem CAPTCHA by Tarso de Melo, poet from São Paulo, published in Alguns Rastros. Stunned by the need to prove that he is a human being, selecting images on the computer screen, the poet ends up being led to a ...
