Population and species neighbor identity impact trait–trait relationships and plant performance

open access: yesPopulation Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...

Management of triplet excitons transition: fine regulation of Förster and dexter energy transfer simultaneously

open access: yesLight: Science & Applications
Understanding and management of triplet excitons transition in the same molecule remain a great challenge. Hence, for the first time, by host engineering, manageable transitions of triplet excitons in a naphthalimide derivative NDOH were achieved, and ...

Recent Progress in Fluorinated Dielectric‐Based Organic Field‐Effect Transistors and Applications

open access: yesAdvanced Sensor Research, 2023
Fluorinated dielectric‐based organic field effect transistors (OFETs) have garnered lots of attention due to some visible superiorities of the incorporation of fluorine functional groups into dielectrics, such as the hydrophobicity, chemical inertness ...

Failed Growth at the Bouncing Barrier in Planetesimal Formation [PDF]

open access: yes, 2016
In laboratory experiments, we studied collisions of ensembles of compact (filling factor 0.33) millimeter dust aggregates composed of micrometer quartz grains. We used cylindrical aggregates, triangular aggregates, square aggregates, and rectangular aggregates. Ensembles of equal size aggregates as well as ensembles with embedded larger aggregates were

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

open access: yesPopulation Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Just-in-Time Aggregation for Federated Learning [PDF]

open access: yesarXiv, 2022
The increasing number and scale of federated learning (FL) jobs necessitates resource efficient scheduling and management of aggregation to make the economics of cloud-hosted aggregation work. Existing FL research has focused on the design of FL algorithms and optimization, and less on the efficacy of aggregation.

Preassociative aggregation functions [PDF]

open access: yes, 2014
The classical property of associativity is very often considered in aggregation function theory and fuzzy logic. In this paper we provide axiomatizations of various classes of preassociative functions, where preassociativity is a generalization of ...

AGGREGATION AND LINEARITY IN THE PROVISION OF INTERTEMPORAL INCENTIVES

open access: yes, 1987
The authors develop two themes in the theory of incentive schemes. First, one need not always use all of the information available in an optimal incentive contract. Accounting information, which aggregates performance over time, is sufficient for optimal

Local Aggregation for Unsupervised Learning of Visual Embeddings [PDF]

open access: yesIEEE International Conference on Computer Vision, 2019
Unsupervised approaches to learning in neural networks are of substantial interest for furthering artificial intelligence, both because they would enable the training of networks without the need for large numbers of expensive annotations, and because ...

Dendritic cells steering antigen and leukocyte traffic in lymph nodes

open access: yesFEBS Letters, EarlyView.
Dendritic cells are key players in the activation of T cells and their commitment to effector function. In this In a Nutshell Review, we will discuss how dendritic cells guide the trafficking of antigen and leukocytes in the lymph node, thus influencing T‐cell activation processes. Dendritic cells (DCs) play a central role in initiating and shaping the
