Trait evolution during a rapid global weed invasion despite little genetic differentiation. [PDF]

open access: yesEvol Appl, 2023
Abstract Invasive species often possess a great capacity to adapt to novel environments in the form of spatial trait variation, as a result of varying selection regimes, genetic drift, or plasticity. We explored the geographic differentiation in several phenotypic traits related to plant growth, reproduction, and defense in the highly invasive ...

From Cosmopolitan to Vernacular in the Language Sciences: A Global History Perspective

open access: yesBerichte zur Wissenschaftsgeschichte, Volume 46, Issue 1, Page 18-37, March 2023., 2023
Abstract Sheldon Pollock's justly famous work on cosmopolitan orders and processes of vernacularization in the worlds of Latinity and Sanskrit invites questions of a comparative and global‐historical character. I will raise such questions in the context of the Persianate cosmopolitan order, especially as exemplified by the early modern Ottoman Empire ...

Experimental admixture among geographically disjunct populations of an invasive plant yields a global mosaic of reproductive incompatibility and heterosis

open access: yesJournal of Ecology, Volume 109, Issue 5, Page 2152-2162, May 2021., 2021
Biogeographic patterns of variation in reproductive success in an invasive weed with allopatric distribution. Abstract Invasive species have the ability to rapidly adapt in the new regions where they are introduced. Classic evolutionary theory predicts that the accumulation of genetic differences over time in allopatric isolation may lead to ...

Nonrelativistic Arbitrary l‐States of Quarkonium through Asymptotic Iteration Method

open access: yesAdvances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
The energy eigenvalues with any l ≠ 0 states and mass of heavy quark‐antiquark system (quarkonium) are obtained by using Asymptotic Iteration Method in the view of nonrelativistic quantum chromodynamics, in which the quarks are considered as spinless for easiness and are bounded by Cornell potential.

Detection Efficiency of NaI(Tl) Detector in 511–1332 keV Energy Range

open access: yesScience and Technology of Nuclear Installations, Volume 2014, Issue 1, 2014., 2014
As it is important to obtain accurate analytical result in an experimental research, this required quality control of the experimental system. Gamma spectrometry system can be used in a variety of different fields such as radiation and medical physics. In this paper the absolute efficiency, peak to valley ratio, and energy resolution of a 3′′ × 3′′ NaI(

Natural Radioactivity Measurements and Radiation Dose Estimation in Some Sedimentary Rock Samples in Turkey

open access: yesScience and Technology of Nuclear Installations, Volume 2014, Issue 1, 2014., 2014
The natural radioactivity existed since creation of the universe due to the long life time of some radionuclides. This natural radioactivity is caused by γ‐radiation originating from the uranium and thorium series and 40K. In this study, the gamma radiation has been measured to determine natural radioactivity of 238U, 232Th, and 40K in collected ...

On the Existence of the Solutions for Some Nonlinear Volterra Integral Equations

open access: yesAbstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013
We present a theorem which gives sufficient conditions for existence of at least one solution for some nonlinear functional integral equations in the space of continuous functions on the interval [0,a]. To do this, we will use Darbo′s fixed‐point theorem associated with the measure of noncompactness. We give also an example satisfying the conditions of
