The Effects of Temperature and Impact Velocity on the Shock Wave Response of Pore-Embedded Metallic Glasses by Indrajit Patra, Ahmed M. Abdulhadi, Fatima Safaa Fahim, Bashar S. Bashar, Taif Alawsi, Mohammad Salmani

“…In this work, the shock wave response of a pore-embedded CuZr metallic glass (PEMG) under different impact velocities (0.5–1.5 km/s) and initial temperatures (300–600 K) was evaluated through the molecular dynamics (MD) simulation. The results indicated that the nucleation and growth of nanoscale shear events around the pore were the dominant mechanisms for plastic deformation under the shock wave. …”

The impact of coarse aggregate mineral compositions on skid resistance performance of asphalt pavement: A comprehensive study. by Chen Zhang, Lihao Zeng, Huimin Wang, Xin Qu

“…Additionally, macroscopic adhesive friction coefficients between polished surfaces of three types of rock slabs (basalt, limestone, granite) and rubber were determined using a pendulum friction tester. Molecular dynamics simulations were employed to model the main aggregate minerals and rubber, and a "sandwich" type constrained shear model was constructed to evaluate micro-scale adhesive friction coefficients. …”

Structure Identification and Risk Assurance of Unknown Impurities in Pramipexole Oral Drug Formulation by Raymond R. Tjandrawinata, Antonius H. Cahyana, Ajeng O. Nugroho, Indra K. Adi, Joseph S. R. Talpaneni

“…Furthermore, observation of the binding affinity potential risk of these impurities to the pramipexole receptor has also been demonstrated through molecular docking and molecular dynamics simulation study. The binding energy result showed that pramipexole interaction with dopamine receptors D2 and D3 was higher than pramipexole mannose adduct and pramipexole ribose adduct.…”

Transport of Alzheimer's associated amyloid-β catalyzed by P-glycoprotein. by James W McCormick, Lauren McCormick, Gang Chen, Pia D Vogel, John G Wise

“…However, previous studies on the ability of P-gp to directly transport the Alzheimer's associated amyloid-β (Aβ) protein have produced contradictory results. Here we use molecular dynamics (MD) simulations, transport substrate accumulation studies in cell culture, and biochemical activity assays to show that P-gp actively transports Aβ. …”

Heat Transport Hysteresis Generated Through Frequency Switching of a Time-Dependent Temperature Gradient by Renai Chen, Galen T. Craven

“…Analytical expressions are derived for the energy fluxes in/out of the system and the baths, with excellent agreement observed between the analytical expressions and the results from nonequilibrium molecular dynamics simulations. We find that the shape of the heat transport hysteresis curves can be significantly altered by shifting the frequency between fast and slow oscillation regimes. …”

Wavelet Analysis of Shower Track Distribution in High-Energy Nucleus-Nucleus Collisions by Provash Mali, Soumya Sarkar, Amitabha Mukhopadhyay, Gurmukh Singh

“…For the first time, the wavelet results are compared with a model prediction based on the ultrarelativistic quantum molecular dynamics (UrQMD), where we adopt a charge reassignment algorithm to modify the UrQMD events to mimic the Bose-Einstein type of correlation among identical mesons—a feature known to be the most dominating factor responsible for local cluster formation. …”

Comparing Standard Distribution and Its Tsallis Form of Transverse Momenta in High Energy Collisions by Rui-Fang Si, Hui-Ling Li, Fu-Hu Liu

“…The experimental (simulated) transverse momentum spectra of negatively charged pions produced at midrapidity in central nucleus-nucleus collisions at the Heavy-Ion Synchrotron (SIS), Relativistic Heavy-Ion Collider (RHIC), and Large Hadron Collider (LHC) energies obtained by different collaborations are selected by us to investigate, where a few simulated data are taken from the results of FOPI Collaboration which uses the IQMD transport code based on Quantum Molecular Dynamics. A two-component standard distribution and the Tsallis form of standard distribution are used to fit these data in the framework of a multisource thermal model. …”
