JDR Clin Trans Res . 2019 Apr; 4(1):58-67. PMID: 30931759
Introduction: Evidence from the adult population suggests that sleep-disordered breathing (SDB) (i.e., obstructive sleep apnea [OSA]) is negatively associated with bone mineral density. Whether a similar association exists in children...

Zhu Y, Hu J, Womack F, Graf D, Wang Y, Adams P, et al.
J Phys Condens Matter . 2019 Mar; 31(24):245703. PMID: 30861508
Topological materials which are also superconducting are of great current interest, since they may exhibit a non-trivial topologically-mediated superconducting phase. Although there have been many reports of pressure-tuned or chemical-doping-induced...

Zvyagin S, Graf D, Sakurai T, Kimura S, Nojiri H, Wosnitza J, et al.
Nat Commun . 2019 Mar; 10(1):1064. PMID: 30842420
Quantum triangular-lattice antiferromagnets are important prototype systems to investigate numerous phenomena of the geometrical frustration in condensed matter. Apart from highly unusual magnetic properties, they possess a rich phase diagram...

Wehinger B, Fiolka C, Lanza A, Scatena R, Kubus M, Grockowiak A, et al.
Phys Rev Lett . 2018 Sep; 121(11):117201. PMID: 30265101
We report an extraordinary pressure dependence of the magnetic interactions in the metal-organic system [CuF_{2}(H_{2}O)_{2}]_{2}pyrazine. At zero pressure, this material realizes a quasi-two-dimensional spin-1/2 square-lattice Heisenberg antiferromagnet. By high-pressure, high-field...

Phys Rev Lett . 2018 Jun; 120(20):206401. PMID: 29864304
We report a de Haas-van Alphen (dHvA) effect study on the Dirac type-II semimetallic candidates MAl_{3} (where, M=V, Nb and Ta). The angular dependence of their Fermi surface (FS) cross-sectional...

J Dent Res . 2018 Mar; 97(7):835-843. PMID: 29489425
Formation of highly organized dental hard tissues is a complex process involving sequential and ordered deposition of an extracellular scaffold, followed by its mineralization. Odontoblast and ameloblast differentiation involves reciprocal...

Nat Commun . 2017 Dec; 8(1):2044. PMID: 29229909
The properties of cuprate high-temperature superconductors are largely shaped by competing phases whose nature is often a mystery. Chiefly among them is the pseudogap phase, which sets in at a...
