Classification and a toolbox for orientifold models

, 2005
We provide the general tadpole conditions for a class of supersymmetric orientifold models by studing the general properties of the elements included in the orientifold group.

Morphometrics and ratio of body proportionality of tadpoles of Rhinella icterica (Anura, Bufonidae) at different developmental stages

Brazilian Journal of Biology
The plasticity of the anurans' development is probably related to their great ecological and geographic diversity. Therefore, the understanding of environmental occupation by tadpoles is related to their morphological peculiarities.

Resummed one-loop gluonic contributions to the color superconducting color charge density vanish

, 2005
It is shown that gluonic corrections to the tadpole diagrams vanish in the 2SC and CFL phases at the order where one might have expected NLO corrections.

Large $N$ limit of irreducible tensor models: $O(N)$ rank-$3$ tensors with mixed permutation symmetry

, 2018
It has recently been proven that in rank three tensor models, the anti-symmetric and symmetric traceless sectors both support a large $N$ expansion dominated by melon diagrams [arXiv:1712.00249 [hep-th]].

Three-loop Correction to the Instanton Density. I. The Quartic Double Well Potential

, 2015
This paper deals with quantum fluctuations near the classical instanton configuration. Feynman diagrams in the instanton background are used for the calculation of the tunneling amplitude (the instanton density) in the three-loop order for quartic double-

Living near humans: new diet items for the Big-headed Treefrog Polypedates megacephalus (Amphibia: Anura: Rhacophoridae) and its tadpoles in Vietnam

Natural History Sciences
The predation by the Big-headed Treefrog Polypedates megacephalus on the Common House Gecko Hemidactylus frenatus and a failed predation attempt on the Tokay Gecko Gekko gecko are reported.

Testing differences in thermal tolerance between two amphibians with contrasting invasion abilities

Frontiers in Ecology and Evolution
Physiological traits may influence the establishment success of non-native species, yet empirical links between physiology and invasiveness remain limited. The American bullfrog (L. catesbeianus) and the green frog (L.

The Composition and Function of Intestinal Microbiota Were Altered in Farmed Bullfrog Tadpoles (Aquarana catesbeiana) during Metamorphosis

Microorganisms
The bullfrog Aquarana catesbeiana is one of the main farmed frog species in China, with a low overall survival of farmed bullfrogs from hatching to harvest since bullfrog tadpoles are fragile during the metamorphosis period.

Bioaccumulation, Ecotoxicity, and Microbial Responses in Hoplobatrachus rugulosus Tadpoles Following Co-Exposure to Imidacloprid and Microplastics

Animals
Agricultural organic pollutants have been identified as a key factor contributing to amphibian population decline, particularly during early developmental stages when tadpoles are frequently exposed to neonicotinoids (NEOs) and microplastics (MPs).
