To investigate unsaturated soil-water interaction at micro-scale, this study extends the numerical manifold method (NMM) by incorporating a coupling model considering specific capillary water distribution and force calculation. The soil skeleton is constructed generation algorithm with random polygons. more realistically capture between grains water, mechanics-based geometric proposed to iterat...

Sr2RuO4 and Fe-pnictide superconductors belong to the same point group symmetry D4h. Many experimental data confirm odd pairs in even Fe-pnictides, but opposite conclusions also exist. Recent NMR results of Pustogow et al., which revealed Cooper Sr2RuO4, require reconsideration treatment its SOP (superconducting order parameter). In present work making use Mackey–Bradley theorem on symmetrized ...

Three-dimensional geological modeling is an important means to transparently study the three-dimensional spatial structure and change trend of major complex rock mass projects, plays a very role in decision-making mining projects. Today’s methods rely too much on required data, process cumbersome time relatively long. Therefore, based above discussion, this article uses complete open source cod...

Hourglass dispersion is generally believed to be solely protected by nonsymmorphic symmetries, because these symmetries can introduce high-dimensional projective representations. Here, based on symmetry arguments, we propose that the hourglass jointly symmorphic and instead of only conventional symmetry. Moreover, using first-principles calculations, realize our proposal in phonon spectra reali...

Energy storage devices are collocated with conventional solar photovoltaic (PV) systems to tackle the intermittency of irradiance and maintain power quality supplied energy. The energy system usually has its own conversion that may incur an extra capital cost installation. This paper proposes integrated cost-effective photovoltaic-supercapacitor (PVSC) in which functionality supercapacitor (SC)...

The aim of this study is to the effect aging in different media (deionized water and artificial saliva) on force/torque generation by thermoplastic orthodontic aligners. Ten thermoformed aligners, made Essix ACE® sheets, were aged deionized saliva over two weeks at 37 °C, five each medium. generated upper second premolar (Tooth 25) a resin model was measured day 0 (before aging), 2, 4, 6, 10, 1...

We study lanthanum mononitride LaN by first-principles calculations. The commonly reported rock-salt structure of $Fm\bar{3}m$ symmetry for rare-earth monopnictides is found dynamically unstable at zero temperature. Using density functional theory and evolutionary crystal prediction, we discover a new, stable with $P1$ 0 K. This $P1$-LaN exhibits spontaneous electric polarization. Our ab initio...

The actual grip force provided by a hand prosthesis is an important parameter to evaluate its efficiency. To this end, split cylindrical handlebar embedding single-axis load cell was designed, 3D printed and assembled. Various measurements were made the performances of “Federica” hand, simple low-cost prosthesis. placed at different angular positions with respect palm, experimental data process...

An estimated 4–8% of all women, and 16–25% women with migraine, have menstrual migraine (MM), which causes considerable disability, but is underdiagnosed undertreated. We investigated the burden disease, health-care seeking behavior, treatment practices among MM, using social media. In 12 days, 6246 answered an online survey, allowing for diagnosis MM by International Classification Headache Di...
