Typhoon Jongdari (2018) took an unusual track along the circumference of upper-tropospheric cold low (UTCL) before making landfall in Japan on 29 July. To investigate effects atmosphere–ocean interactions and between UTCL storm's track, numerical simulations were conducted with a 3-km-mesh nonhydrostatic atmosphere model atmosphere–wave–ocean coupled model, using different initial conditions cr...

in this work, different types of chaotic 1-manifolds which lie on the chaotic spheres or on a torus are introduced. some types of retractions of the chaotic spheres affect on the 1-chaotic systems, and other types of retractions occur to the geometric manifold but make the 1-chaotic manifold invariant. the existed retractions are discussed through new proved theorems. also we construct diffe...

Abstract Protein folding has attracted considerable research effort in biochemistry recent decades. In this work, we explore the potential of quantum computing to solve a simplified version protein folding. More precisely, numerically investigate performance Quantum Approximate Optimization Algorithm (QAOA) sampling low-energy conformations short peptides. We start by benchmarking algorithm on ...

Recently, protein-folding models have advanced to the point where folding simulations of protein-like chains of reasonable length (up to 125 amino acids) are feasible, and the major physical features of folding proteins, such as cooperativity in thermodynamics and nucleation mechanisms in kinetics, can be reproduced. This has allowed deep insight into the physical mechanism of folding, includin...

Simulations with the Weather Research and Forecasting (WRF) cloud-resolving model of deep moist convective events reveal net cooling near the tropopause ( 15–18 km above ground), caused by a combination of large-scale ascent and small-scale cooling by the irreversible mixing of turbulent eddies overshooting their level of neutral buoyancy. The turbulent cooling occurred at all CAPE values inves...

The retrieval of the tropospheric ozone column from satellite data is very important for the characterization of tropospheric chemical and physical properties. However, the task of retrieving tropospheric ozone from space has to face with one fundamental difficulty: the contribution of the tropospheric ozone to the measured radiances is overwhelmed by a much stronger stratospheric signal, which...

-An improved genetic algorithm applies the optimization procedures of protein folding through defining a new move set in lattice model. The new move set including rotation and mirror reflection is suitable for use in protein folding simulation. Through folding simulation on a simple lattice model it is found that the new move set is dramatically superior to that of the commonly used move set.
