A 60-year-old woman, free of other disease, with severe clinical hyperthyroidism had normal total serum T4 with elevated free T4 concentration and T3 resin uptake characteristic of hyperthyroidism, with thyroid binding globulin (TBG) deficiency. However, serum TBG concentration as determined by immunoassay was normal, suggesting that the biochemical defect affecting the T4 binding sites did not...

The mechanism of charge carrier interaction in twisted bilayer graphene (TBG) remains an unresolved problem, where some researchers proposed the dominance electron–phonon interaction, while others showed evidence for electron–electron or electron–magnon interactions. Here we propose to resolve this problem by generalizing Bloch–Grüneisen equation and using it analysis temperature dependent resi...

The structural and electronic properties of twisted bilayer graphene (TBG) on SiC(000) grown by Si flux-assisted molecular beam epitaxy were investigated using scanning tunneling microscopy (STM) and angle-resolved photoelectron spectroscopy with nanometric spatial resolution. STM images revealed a wide distribution of twist angles between the two graphene layers. The electronic structure recor...

We demonstrate a time-domain distributed temperature sensing based on birefringence effect on transient Brillouin grating (TBG) in a polarization-maintaining photonic crystal fiber (PM-PCF), which uses two short pump pulses (2 ns) to excite a TBG and a long probe pulse (6 ns) to map the transient Brillouin grating spectrum (TBGS) associated with the birefringence. The 2 ns pump pulses defines a...

We construct a heavy fermion representation for twisted bilayer graphene (TBG) systems. Two local orbitals (per spin/valley) are analytically found, which exactly the maximally localized zero modes of continuum Hamiltonian near AA-stacking center. They have similar properties to Wannier functions found in recent study, but also clear interpretation as zeroth pseudo Landau levels (ZLL) Dirac fer...

Electronic properties of quantum dots (QDs) depend sensitively on their parent materials. Therefore, confined electronic states in graphene QDs (GQDs) monolayer and Bernal-stacked bilayer are quite different. Twisted (TBG) is distinct from because the new degree freedom: twist angle. In past few years, numerous efforts have been made to realize GQDs achieved great success. Thus far, however, st...

Hemicastration of males increases weight of remaining testis when conducted before Sertoli cells cease to proliferate. The current studies re-examined responses to hemicastration in one-quarter Meishan crossbred boars that differed for two alleles of thyroid-binding globulin (TBG). In the first experiment, boars at 25 days of age with either allele did not differ in degree of testicular develop...

Twisted bilayer graphene (TBG) provides an example of a system in which the interplay interlayer interactions and superlattice structure impacts electron transport variety non-trivial ways gives rise to plethora interesting effects. Understanding mechanisms scattering TBG has, however, proven challenging, raising many questions about origins resistivity this system. Here we show that exhibits h...

BACKGROUND Several ubiquitous polyhalogenated compounds (PHCs) have been shown to alter thyroid function in animal and in vitro studies. So far, epidemiologic studies have focused on the potential effect of a small number of them, namely, polychlorinated biphenyls (PCBs) and some organochlorines (OCs), without paying attention to other important PHCs. OBJECTIVES We investigated the relationsh...
