Abstract The masses of pion and sigma meson modes, along with their dissociation in the quark medium, provide detailed spectral structures of the chiral partners. One has seen collectivity in pA and pp systems both at LHC and RHIC. In this article, we study the restoration of chiral symmetry by investigating the finite size effect on the detailed structure of the chiral partners in the framework of the Nambu-Jona-Lasinio model. Their diffusions and conductions have been studied through this dissociation mechanism. It is found that the masses, widths, diffusion coefficients, conductivities of chiral partners merge at different temperatures in the restoration phase of chiral symmetry. However, merging points are shifted to lower temperatures when one introduces the finite size effect into the picture. The strengths of diffusions and conductions are also reduced once the finite size is introduced in the calculations.

The article focuses on the types of masses and their symbols according to Elias Canetti, which he presents in his large-scale work Masses and Power. The main forms of the masses are classified, according to their functional characteristics. Various natural phenomena and clusters are natural combinations of symbolic significance, carried away from ancient times to the present day through myths, traditions, dreams, speech. Analogies are examined between the natural symbols of masses, which are absorbed and carried by man as attributes of the masses in the social reality.

With the rapid development of society and economy, grassroots organizations in rural pastoral areas are an important part of party building, shouldering the mission of implementing party policies, and playing an important role in leading herdsmen to fight poverty and realize basic modernization in rural areas. The mission and responsibilities of grassroots party organizations in rural and pastoral areas are undergoing profound changes. Strengthening the construction of grassroots party organizations in rural and pastoral areas will help promote the relationship between the party and the masses, cadres and the masses in rural and pastoral areas, and promote the establishment of party organizations in rural and pastoral areas. At present, grassroots party building in rural pastoral areas is facing new challenges, such as insufficient party organization building, and unclear power boundaries between party organizations and villagers’ autonomous organizations. Only by accelerating the construction of infrastructure and public services in rural pastoral areas and doing a good job in the construction of rural grassroots party organizations can improve the level of party building in rural pastoral areas and promote the basic modernization of rural areas.

The article analyzes the totalitarian communist anti-religious and anti-clerical rhetoric developed în the context of the utopian project of atheism of the Soviet people. It is shown that the process of asserting atheism in the Soviet space was a component of the monoideologized cultural policy subordinated to the program of training the new man. Along with the analysis of some official reference documents regarding the development of the activity of atheist education of the masses, the work of several researchers from the national space is elucidated who have become remarkable through their approaches to this subject: A.Babii, D.Tabacaru, M.Goldenberg etc.

Abstract Dynamical studies of dense structures within molecular clouds often conclude that the most massive clumps contain too little kinetic energy for virial equilibrium, unless they are magnetized to an unexpected degree. This raises questions about how such a state might arise, and how it might persist long enough to represent the population of massive clumps. In an effort to reexamine the origins of this conclusion, we use ammonia line data from the Green Bank Ammonia Survey and Planck-calibrated dust emission data from Herschel to estimate the masses and kinetic and gravitational energies for dense clumps in the Gould Belt clouds. We show that several types of systematic error can enhance the appearance of low kinetic-to-gravitational energy ratios: insufficient removal of foreground and background material; ignoring the kinetic energy associated with velocity differences across a resolved cloud; and overcorrecting for stratification when evaluating the gravitational energy. Using an analysis designed to avoid these errors, we find that the most massive Gould Belt clumps harbor virial motions, rather than subvirial ones. As a by-product, we present a catalog of masses, energies, and virial energy ratios for 85 Gould Belt clumps.

AbstractWe study the masses and lifetimes of doubly charmed pentaquark $$P_{cc{\bar{q}}qq}(q=u,d,s)$$ P c c q ¯ q q ( q = u , d , s ) primarily. The operation of masses carried out by the doubly heavy triquark-diquark model, whose results suggests the existence of stable states $$cc{\bar{s}} ud$$ c c s ¯ u d with the parity $$J^P=\frac{1}{2}^-$$ J P = 1 2 - . The roughly calculation about lifetimes show the short magnitudes, $$(4.65^{+0.71}_{-0.55})\times 10^{-13}s $$ ( 4 . 65 - 0.55 + 0.71 ) × 10 - 13 s for the parity $$J^P=\frac{1}{2}^-$$ J P = 1 2 - and $$(0.93^{+0.14}_{-0.11})\times 10^{-12} s $$ ( 0 . 93 - 0.11 + 0.14 ) × 10 - 12 s for $$J^P=\frac{3}{2}^-$$ J P = 3 2 - . Since the pentaquark $$cc{\bar{s}} ud$$ c c s ¯ u d is interpreted as the stable bound states against strong decays, then we will focus on the production and possible decay channels of the pentaquark in the next step, the study would be fairly valuable supports for future experiments. For completeness, we systematically studied the production from $$\Omega _{ccc}$$ Ω ccc and the decay modes in the framework SU(3) flavor symmetry, including the processes of semi-leptonic and two body non-leptonic decays. Synthetically, we make a collection of the golden channels.
