Revised Age Estimates for Northern Resident Killer Whales (Orcinus orca) Based on Observed Life‐History Events and Demographic Discounting

open access: yesEcology and Evolution, Volume 15, Issue 3, March 2025.
Even some long‐term studies must rely on estimated ages when particularly long‐lived species are involved. Using empirical probabilities of life‐history event timing, we update age estimates for Northern Resident killer whales that were born before the start of observation, five decades ago.

Local solutions with infinite energy of the Maxwell-Chern-Simons-Higgs system in Lorenz gauge [PDF]

open access: yesarXiv, 2014
We consider the Maxwell-Chern-Simons-Higgs system in Lorenz gauge and use a null condition to show local well-psoedness for low regularity data. This improves a recent result of J. Yuan.

Congruency between word position and meaning is caused by task Induced spatial attention

open access: yesFrontiers in Psychology, 2010
We report an experiment that compared two explanations for the effect of congruency between a word’s on screen spatial position and its meaning.

Low regularity solutions for Chern-Simons-Dirac systems in the temporal and Coulomb gauge [PDF]

open access: yesElectr. J. Diff. Equ. 2016(2016), No. 174, 1-16, 2015
We prove low regularity local well-posedness results in Bourgain-Klainerman-Machedon spaces for the Chern-Simons-Dirac system in the temporal gauge and the Coulomb gauge. Under slightly stronger assumptions on the data we also obtain "unconditional" uniqueness in the natural solution spaces.

Helicenes: The Photochemical Ring-Closure of Polymer-Supported 1,2-Diarylethylenes: Hexahelicene- and benzo[c]phenanthrene-2-carbaldehyde

open access: yesCHIMIA, 1975
Photolysis of a suspension (C6H6;I2) of 1-(4-formylphenyl)-2-(2-benzo[c]phenanthryl)ethylene and 1-(4-formylphenyl)-2-(2-naphthyl)ethylene anchored on a styrene-divinylbenzene copolymer (1a and 1b), followed by hydrolysis, yielded hexahelicene-2 ...

Discourse comprehension and simulation of positive emotions [PDF]

open access: yes, 2014
Recent research has suggested that emotional sentences are understood by constructing an emotion simulation of the events being described. The present study aims to investigate whether emotion simulation is also involved in online and offline ...

Service selection and switching decisions: user behavior in high-interoperability environments

open access: yesHumanities & Social Sciences Communications
Current legislation and market dynamics require and encourage systems to become more open and interoperable. Given this shift, the challenge arises as to how service providers can navigate such environments and whether and how known platform economics ...

Determination of Novel Highly Effective Necrostatin Nec-1s in Rat Plasma by High Performance Liquid Chromatography Hyphenated with Quadrupole-Time-of-Flight Mass Spectrometry

open access: yesMolecules, 2018
Necrostatins have been shown to retard necroptosis, a programmed necrotic-like cell death, which has been shown to underlie pathophysiology of various diseases.

Global well-posedness below energy space for the 1D Zakharov system [PDF]

open access: yesarXiv, 2000
The Cauchy problem for the 1-dimensional Zakharov system is shown to be globally well-posed for large data which not necessarily have finite energy. The proof combines the local well-posedness result of Ginibre, Tsutsumi, Velo and a general method introduced by Bourgain to prove a similar result for nonlinear Schr\"odinger equations.

Large data pointwise decay for defocusing semilinear wave equations

open access: yes, 2010
We generalize the pointwise decay estimates for large data solutions of the defocusing semilinear wave equations which we obtained earlier under restriction to spherical symmetry.
