Improving lattice perturbation theory [PDF]

, 1995
Lepage and Mackenzie have shown that tadpole renormalization and systematic improvement of lattice perturbation theory can lead to much improved numerical results in lattice gauge theory.

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

Environmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Tadpole Domination in Graphs

مجلة بغداد للعلوم, 2018
A new type of the connected domination parameters called tadpole domination number of a graph is introduced. Tadpole domination number for some standard graphs is determined, and some bounds for this number are obtained. Additionally, a new graph, finite,

Ranid Herpesvirus 3 Infection in Common Frog Rana temporaria Tadpoles

Emerging Infectious Diseases, 2023
Ranid herpesvirus 3 (RaHV3) is a recently discovered virus associated with skin disease in frogs. We detected RaHV3 DNA in free-ranging common frog (Rana temporaria) tadpoles, consistent with premetamorphic infection.

A calculation of the Lepage-Mackenzie scale for the lattice axial and vector currents

, 1998
We calculate the perturbative scales (q*) for the axial and vector currents for the Wilson action, with and without tadpole improvement, using Lepage and Mackenzie's formalism.

Gauge-independent $\overline{MS}$ renormalization in the 2HDM [PDF]

, 2012
We present a consistent renormalization scheme for the CP-conserving Two-Higgs-Doublet Model based on $\overline{MS}$ renormalization of the mixing angles and the soft-$Z_2$-symmetry-breaking scale $M_{sb}$ in the Higgs sector.

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Constraints on Low-Dimensional String Compactifications [PDF]

, 1996
We study the restrictions imposed by cancellation of the tadpoles for two, three, and four-form gauge fields in string theory, M-theory and F-theory compactified to two, three and four dimensions, respectively.

Health Biomarkers of Pesticide Exposure in Rural Populations of Santa Fe, Argentina: Oxidative Stress and Genotoxicity

Journal of Applied Toxicology, EarlyView.
ABSTRACT The present study aimed to quantify pesticide residues in environmental matrices and plasma and to evaluate their potential effects on oxidative stress and DNA damage in rural populations of Santa Fe province. Soil and rainwater samples were collected, and biological samples and semistructured surveys were obtained from volunteers in three ...

Numbers, neighbors, and hungry predators: What makes chemically defended aposematic prey susceptible to predation?

Ecology and Evolution, 2020
Many chemically defended aposematic species are characterized by relatively low toxin levels, which enables predators to include them in their diets under certain circumstances.
