We conducted organic geochemical analyses on the largest suite of oils and source-rock extracts from Tarim basin, northwest China, currently available. Statistical cluster analysis entire distinguishes at least seven genetic groups oils. The group was collected Tazhong Tabei uplifts originated marine Middle-Upper Ordovician anoxic marls that mark slope facies margins structural uplifts. Two other most likely source rocks, but distinct facies, with one an oxic shale-rich west Bachu uplift...
We study symmetric and asymmetric optical multi-peak solitons on a continuous wave background in the femtosecond regime of single-mode fiber. Key characteristics such solitons, as formation mechanism, propagation stability, shape-changing collisions, are revealed detail. Our results show that this (symmetric or asymmetric) mode could be regarded single pulse formed by nonlinear superposition periodic single-peak (W-shaped antidark) soliton. In particular, phase diagram for different types...
We study the correspondence between modulational instability and types of fundamental nonlinear excitation in a fiber with both third-order fourth-order effects. Some soliton excitations are obtained regime which have not been found fibers second-order effects Explicit analysis suggests that existence solitons is related to modulation stability circle regime, they just exist outside circle. It should be emphasized only two special profiles on continuous-wave background at certain frequency....
This study proposes the use of active lateral secondary suspension (ALS) to address low-frequency carbody swaying in high-speed rail vehicles under low wheel-rail conicity conditions. Field experiments reveal acceleration exceeding 0.10 g at a dominant frequency 1.4 Hz, with Sperling index 3.0 during occurs. By integrating field-measured wheel/rail profiles and yaw damper parameters into multibody dynamics model vehicle system, coupling between bogie hunting upper-center roll modes is...

We study the effect of relative phase on characteristics rogue waves and solitons described by rational solutions in nonlinear Schrödinger Maxwell–Bloch system. derived wave soliton with adjustable present parameter range different types solitons. Our findings show that can alter distribution even change type solitons, leading to a rich array adjusting phase. However, does not affect structure wave, because changes during evolution. In particular, we confirm varying phases at corresponding...
We study the excitation conditions of antidark solitons and nonrational W-shaped in a nonlinear fiber with both third-order fourth-order effects. show that relative phase can be used to distinguish solitons. The these well-known fundamental waves (on continuous-wave background) clarified clearly by three previously reported parameters (background frequency, perturbation energy). Moreover, numerical simulations from nonideal initial states also support theoretical results. These results...
We study rogue wave excitation dynamics on a double-plane background through deriving solution the background. The results indicate that still can be excited successfully from resonant perturbations with two plane backgrounds. obtained vector decomposed to waves located backgrounds separately. This enables us investigate superpositions of three well-known fundamental patterns, mainly including eye-shaped, anti-eye-shaped, and four-petaled one. explicit conditions for different possible are...
We study localized waves on continuous wave background in an exponential dispersion decreasing fiber with two orthogonal polarization states. demonstrate that asymmetric W-shaped and M-shaped soliton pulse can be generated from a weak modulation background. The numerical simulation results indicate the pulses are robust against small noise or perturbation. In particular, degree of effectively controlled by changing relative frequency components. This character used to generate other...
