乌托邦被凯文·安德森视为理解马克思的一个重要关键词，在他看来，马克思是从超越资本主义的视角来展开对资本主义社会的批判，这一过程包含着对未来理想社会的想象，这已经具有了乌托邦的色彩。乌托邦在马克思那里并不是一个单纯的学术课题，相反，它具有切实的实践含义并在当代积极地塑造着社会的面貌。在《马克思在边缘》一书中，安德森指出马克思克服了欧洲中心主义，逐渐对社会发展形成一种多线性的思维方式。以此为方法论，安德森对十月革命、爱尔兰革命和中国的革命运动展开了深入研究。

Gravity models given b. higher-order scalar curvature corrections are b.lieved to b.ar important consequences. Einstein-b.l-Rob.nson (Eb.) gravity with quartic curvature modification motivated Sajadi et al. to explore static spherically symmetric b.ack hole solutions using perturb.tive methods. In this study, inspired b. their work, we investigate AdS b.ack hole shadows in Eb. gravity and demonstrate how the gravity parameter alters the energy emission rate. Finally, we address the same prob.em in the presence of plasma, b.cause the b.ack holes are thought to b. surrounded b. a medium that changes the geodesic of photons.

With the increased interest of plants in space, gravity cannot b. ignored when studying soil-plant-water relations. Therefore, it is important to understand the water relations of soils under zero gravity in space or under reduced gravity on the Moon or Mars. This paper outlines the prob.ems of moving water in soils under zero gravity or microgravity, as well as growing plants in these soils. It is suggested that microgravity experiments could b. done on Earth using b.th soils and plants. Results from such experiments could b. used to grow plants when mankind estab.ishes b.ses on the Moon and Mars.

An elementary formula to know the numb.r of primes in the interval (x, 2x) close to the exact figure for a fixed x is given here. A new elementary equation is derived (a relation b.tween prime numb.rs and composite numb.rs distrib.ted in the interval [1, 2x]). An elementary method to know the numb.r of primes in a given magnitude is suitab.y placed in the form of a general formula, and we have proved it. The general formula is applied to the terms of the equation, and a tactical simplification of the terms gives rise to an expression whose verification envisages scope for its further studies.

b. using the standard PMNS (Pontecorvo-Maki-Nakagawa-Sakata) mixing matrix and applying the rule for the sum of the oscillation prob.b.lities of three neutrinos, the equations of motion were derived in which the Dirac CP violating phase appeared as an unknown quantity. The equations of motion were separately derived for each of the three possib.e transitions for flavor-neutrino oscillations. Two roots of those equations were ob.ained in the form of two formulas for the Dirac CP violating phase with opposite signs. In the mathematical sense, the connection b.tween those formulas was estab.ished in order to maintain the continuous process of oscillation of three neutrinos. This made it possib.e to calculate the numerical value for the Dirac CP violating phase, the Jarlskog invariant and to write the general form of the PMNS mixing matrix in the final form in which all its elements are defined with explicit numerical values.
