Addition of sodium salicylate to human serum at concentrations often obtained during aspirin therapy causes 100-200% increases in free triiodothyronine (T(3)) and free thyroxine (T(4)) as estimated by ultrafiltration. The increase in free T(3) was unexpected since previous data had suggested that salicylate inhibits binding of T(4) only to thyroxine-binding prealbumin (TBPA) and that T(3) is no...

OBJECTIVES The aim of the study was to determine the evolution of thyroid tests throughout pregnancy and postpartum in healthy women with and without iodine supplementation. METHODS This was a prospective, randomized, interventional study of iodine supplementation (150 μg/day) from the first trimester until 3 months postpartum versus controls. 111 pregnant women with normal initial thyroid te...

When two periodic two-dimensional structures are superposed, any mismatch rotation angle between the layers generates a Moiré pattern superlattice, whose size depends on twisting θ. If composed by different materials, this effect is also dependent lattice parameters of each layer. superlattices commonly observed in bilayer graphene, where can be produced growing twisted graphene (TBG) samples C...

We derive the exact insulator ground states of projected Hamiltonian magic-angle twisted bilayer graphene (TBG) flat bands with Coulomb interactions in various limits, and study perturbations away from these limits. define (first) chiral limit where AA stacking hopping is zero, a exactly bands. In chiral-flat limit, TBG has U(4)$\times$U(4) symmetry, we find that at integer filling $-4\le \nu\l...

The electronic wave functions in moir\'e materials are highly sensitive to the details of local atomic configuration enabling Bloch band geometry and topology be controlled by stacking strain. Here, we predict that large injection currents (under circularly polarized irradiation) can develop strained twisted bilayer graphene (TBG) heterostructures with broken sublattice symmetry; such bulk phot...

We show that for the magic-angle twisted bilayer graphene (TBG) away from charge neutrality point, although quantum Monte Carlo (QMC) simulations suffer sign problem, computational complexity is at most polynomial integer fillings of flat-band limit. For even-integer fillings, survives even if an extra intervalley attractive interaction introduced. This observation allows us to simulate TBG and...

Strongly interacting electrons in solid-state systems often display tendency towards multiple broken symmetries the ground state. The complex interplay between different order parameters can give rise to a rich phase diagram. Here, we report on identification of intertwined phases with rotational symmetry magic-angle twisted bilayer graphene (TBG). Using transverse resistance measurements, find...
