Vitamin D receptor gene polymorphisms as a risk factor for obesity in Saudi men
Electronic Physician, 2017 Background: The prevalence of obesity and vitamin D deficiency in Saudi Arabia has increased recently. Decreased physical activity might play a role in obesity.

Assessment of mechanical, thermal properties and crystal shapes of monoclinic tricalcium silicate from atomistic simulations [PDF]
Cement and Concrete Research. 140 (2021) 106269, 2020 The two most common polymorphs in industrial alite, $M_1$ and $M_3$, were characterized at the molecular scale. Different methods were employed and discussed to assess mechanical properties and specific heat of both polymorphs. The calculated homogenized elastic moduli and specific heat were found in good agreement with experimental measurements.

Physics-guided descriptors for prediction of structural polymorphs [PDF]
J. Phys. Chem. Lett. 2022, 13, 31, 7342, 2022 We develop a method combining machine learning (ML) and density functional theory (DFT) to predict low-energy polymorphs by introducing physics-guided descriptors based on structural distortion modes. We systematically generate crystal structures utilizing the distortion modes and compute their energies with single-point DFT calculations. We then train

Diffusion Monte Carlo Study on Relative Stabilities of Boron Nitride Polymorphs [PDF]
, 2021 Although Boron nitride (BN) is a well-known compound widely used for engineering and scientific purposes, the phase stability of its polymorphs, one of its most fundamental properties, is still under debate. The ab initio determination of the ground state of the BN polymorphs, such as hexagonal and zinc-blende, is difficult because of the elusive Van ...

Anharmonic electron-phonon coupling in ultrasoft and locally disordered perovskites [PDF]
npj Comput Mater 9, 153 (2023), 2023 Anharmonicity and local disorder (polymorphism) are ubiquitous in perovskite physics, inducing various phenomena observed in scattering and spectroscopy experiments. Several of these phenomena still lack interpretation from first-principles since, hitherto, no approach is available to account for anharmonicity and disorder in electron-phonon couplings.

Generating Code with Polymorphic let: A Ballad of Value Restriction, Copying and Sharing [PDF]
EPTCS 241, 2017, pp. 1-22, 2017 Getting polymorphism and effects such as mutation to live together in the same language is a tale worth telling, under the recurring refrain of copying vs. sharing. We add new stanzas to the tale, about the ordeal to generate code with polymorphism and effects, and be sure it type-checks.

The algebraic dichotomy conjecture for infinite domain Constraint Satisfaction Problems [PDF]
Logic in Computer Science, 2016 We prove that an ω-categorical core structure primitively positively interprets all finite structures with parameters if and only if some stabilizer of its polymorphism clone has a homomorphism to the clone of projections, and that this happens if and ...

Correlations between MDM2 gene SNP309 Polymorphism and Susceptibility to Leukemia
Medical Science Monitor, 2015 Background The objective of this study was to perform a systematic review of correlations between the single-nucleotide polymorphism at nucleotide 309 (single-nucleotide polymorphism, SNP309) in the murine double-minute 2 (MDM2) gene promoter and ...
