Preferences for Domestic Action Over International Transfers in Global Climate Policy [PDF]

open access: yes, 2018
Cost-effective and equitable climate change mitigation requires the transfer of resources from developed to developing countries. In two behavioral experiments, we demonstrate that American subjects act according to a strong home preference, by making ...

Combining Ability and Heterosis for Market Yield in Green Asparagus

open access: yesHorticulturae, 2022
In asparagus, current cultivars are mostly hybrids (known as clonal hybrids) derived from crosses between two parents, female and male, with good combining ability.

Performance of maize single-crosses developed from populations improved by a modified reciprocal recurrent selection Performance de híbridos simples de milho desenvolvidos de populações melhoradas por seleção recorrente recíproca modificada

open access: yesScientia Agricola, 2010
Maize (Zea mays L.) elite inbred lines developed from pedigree programs tend to be genetically related. Therefore, it is necessary to incorporate unrelated inbreds to those programs to allow the continued release of outstanding single-crosses.

Experimental Simulation of Retrodirective Cross-Eye Jamming [PDF]

open access: yesIEEE Transactions on Aerospace and Electronic Systems, 2011
Experimental measurements that accurately simulate the effect of a retrodirective cross-eye jammer on a monopulse radar are described. The accuracy of a recently published extended analysis of retrodirective cross-eye jamming and the limitations of the conventional phase-front analysis of cross-eye jamming are illustrated by the experiments.

Kinship and altruism: A cross‐cultural experimental study [PDF]

open access: yesBritish Journal of Psychology, 2007
Humans are characterized by an unusual level of prosociality. Despite this, considerable indirect evidence suggests that biological kinship plays an important role in altruistic behaviour. All previous reports of the influence of kin selection on human altruism have, however, used correlational (rather than experimental) designs, or imposed only a ...

One Genome, Multiple Phenotypes: Would Rhodnius milesi Carcavallo, Rocha, Galvão & Jurberg, 2001 (Hemiptera, Triatominae) Be a Valid Species or a Phenotypic Polymorphism of R. neglectus Lent, 1954?

open access: yesDiversity
Species of the Rhodnius genus have a complex taxonomy because the events of phenotypic plasticity and cryptic speciation make it difficult to correctly classify these vectors. During the taxonomic history of the genus, five synonymization events occurred.

The Dynamics of Non-Crystalline Silica: Insight from Molecular Dynamics Computer Simulations [PDF]

open access: yes, 1998
Using a large scale molecular dynamics computer simulation we investigate the dynamics of a supercooled melt of SiO_2. We find that with increasing temperature the temperature dependence of the diffusion constants crosses over from an Arrhenius-law, with

DCN V2: Improved Deep & Cross Network and Practical Lessons for Web-scale Learning to Rank Systems [PDF]

open access: yesThe Web Conference, 2020
Learning effective feature crosses is the key behind building recommender systems. However, the sparse and large feature space requires exhaustive search to identify effective crosses.

Flory-Huggins theory for the solubility of heterogeneously-modified polymers

open access: yes, 2007
Many water soluble polymers are chemically modified versions of insoluble base materials such as cellulose. A Flory-Huggins model is solved to determine the effects of heterogeneity in modification on the solubility of such polymers.
