In a framework of a multi-phase transport model with both partonic and hadronic interactions, azimuthal correlations between trigger particles and associated scattering particles (3 < p T < 6 GeV/c and 0.15 < p T < 3 GeV/c (soft), or 2.5 < p trig T < 4 GeV/c and 1 < p assoc T < 2.5 GeV/c (hard)) in Au + Au collisions at √ sNN = 200 GeV have been studied by the mixing-event technique, and Mach-l...

We have previously reported the detection of two unusual nucleotides, pdJ and pdV, in the DNA of Trypanosoma brucei (Gommers-Ampt et al., 1991). pdJ was found to be a novel nucleotide and is possibly involved in the regulation of variant specific surface antigen gene expression in trypanosomes. Recent evidence suggests that V could be a precursor of J, making V a key compound in the study of th...

The azimuthal correlations between local flow planes at different (pseudo)rapidities ($\ensuremath{\eta}$) may reveal important details of the initial nuclear matter density distributions in heavy-ion collisions. Extensive experimental measurements a factorization ratio (${r}_{2}$) and its derivative (${F}_{2}$) have shown evidence longitudinal flow-plane decorrelation. However, nonflow effects...

For the concerns of investigating viscoelastic properties recycled asphalt mixtures incorporating high content reclaimed styrene-butadiene-styrene (SBS) modified pavement (RAP-SBS), mixture performance tester (AMPT) was applied to analyze dynamic modulus and phase angle by influence RAP-SBS content, temperature, loading frequency, long-term aging (LOTA), incorporation a rejuvenating agent. Mast...

$\ensuremath{\alpha}$-clustering structure is a significant topic in light nuclei. A Bayesian convolutional neural network (BCNN) applied to classify initial nonclustered and clustered configurations, namely Woods-Saxon distribution three-$\ensuremath{\alpha}$ triangular (four-$\ensuremath{\alpha}$ tetrahedral) for $^{12}\mathrm{C}$ $(^{16}\mathrm{O})$, from heavy-ion collision events generated...

Correlations between moments of different flow coefficients are measured in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV recorded with the ALICE detector. These new measurements based on multiparticle mixed harmonic cumulants calculated using charged particles pseudorapidity region $|\eta|<0.8$ transverse momentum range $0.2 < p_{\rm T} 5.0$ GeV/$c$. The centrality dependence correlations...

The global polarization of ? hyperons along the total orbital angular momentum a relativistic heavy-ion collision is presented based on high statistics data samples collected in Au+Au collisions at sNN=2.4 GeV and Ag+Ag 2.55 with High-Acceptance Di-Electron Spectrometer (HADES) GSI, Darmstadt. This first measurement below strangeness production threshold nucleon-nucleon collisions. Results are ...

The process of infiltration is one of the most important components of the hydrological cycle. On the other hand, the direct measurement of infiltration process is difficult, time spending and expensive. Infiltration models play a main role in managing water resources. Therefore, different types of models with various degrees of complexity were developed to reach this aim.  So, this research ca...

Anisotropic flow is accredited to have effects from the initial state geometry and fluctuations in nuclear overlap region. The elliptic (${v}_{2}$) triangular (${v}_{3}$) coefficients of final particles are expected influenced by eccentricity (${ϵ}_{2}$) triangularity (${ϵ}_{3}$) participants, respectively. In this work, we study ${v}_{2}$, ${v}_{3}$, ${ϵ}_{2}$, ${ϵ}_{3}$, correlations among th...
