Infection of Mammary Glands of Small Mammals in Eastern North America by Helminths

open access: yesAnimals, 2021
To determine whether small mammals living in natural settings harbor helminth infections in their mammary glands, we conducted a survey of helminths infecting rodents and soricimorphs in three widespread locations in the eastern United States: states of ...

Giant magnetic field from moiré induced Berry phase in homobilayer semiconductors [PDF]

open access: yesNational Science Review, 2019
When quasiparticles move in condensed matters, the texture of their internal quantum structure as a function of position and momentum can give rise to Berry phases that have profound effects on the material’s properties.

Berry phase in superconducting multiterminal quantum dots [PDF]

open access: yes, 2020
We report on the study of the non-trivial Berry phase in superconducting multiterminal quantum dots biased at commensurate voltages. Starting with the time-periodic Bogoliubov-de Gennes equations, we obtain a tight binding model in the Floquet space, and

1-[2,6-Dimethyl-4-(pent-4-yn-1-yloxy)phenyl]-4-phenyl-1,2,4-triazolidine-3,5-dione

open access: yesMolbank, 2023
Urazolyl radicals are a class of persistent nitrogen-centered radicals. In a previous work, we successfully formed self-assembled monolayers of substituted urazolyl radicals on gold surfaces. To extend the scope of these investigations, we sought to form

Reinvestigation of the Room Temperature Photochemical Reaction between N-Methyl-1,2,4-triazoline-3,5-dione (MeTAD) and Benzene

open access: yesOrganics, 2023
The photochemical reaction of N-methyl-1,2,4-triazoline-3,5-dione (MeTAD) with benzene is known to lead to a Diels–Alder cycloaddition product when conducted at low temperatures (i.e.,

Large anomalous Hall effect driven by a nonvanishing Berry curvature in the noncolinear antiferromagnet Mn3Ge [PDF]

open access: yesScience Advances, 2015
A large anomalous Hall effect is observed in the triangular antiferromagnet Mn3Ge arising from an intrinsic electronic Berry phase. It is well established that the anomalous Hall effect displayed by a ferromagnet scales with its magnetization. Therefore,

Topological quantum phase transition and the Berry phase near the Fermi surface in hole-doped quantum wells [PDF]

open access: yes, 2007
We propose a topological quantum phase transition for quantum states with different Berry phases in hole-doped III-V semiconductor quantum wells with bulk and structure inversion asymmetry.

Plasma cell-free DNA 5-hydroxymethylcytosine and whole-genome sequencing signatures for early detection of esophageal cancer

open access: yesCell Death and Disease, 2023
Esophageal cancer is a highly incidence and deadly disease with a poor prognosis, especially in developing countries. Owing to the lack of specific symptoms and early diagnostic biomarkers, most patients are diagnosed with advanced disease, leading to a ...

Strain Engineering of the Berry Curvature Dipole and Valley Magnetization in Monolayer MoS_{2}. [PDF]

open access: yesPhysical Review Letters, 2019
The Berry curvature dipole is a physical quantity that is expected to allow various quantum geometrical phenomena in a range of solid-state systems. Monolayer transition metal dichalcogenides provide an exceptional platform to modulate and investigate ...
