Based on the author's previous argument of the constant existence of the subject of quantum measurement in the framework of the classicalized holographic tensor network, for two quantum measuring systems $M_1$ and $M_2$ in the bulk spacetime, we calculate the result of the processes $(((M_1)_{\rm I}-M_1)_{\rm II}+M_2)_{\rm III}$ as the subject of quantum measurement. This process is obtained from the process $(((M_1)_{\rm I}+M_2)_{\rm II}-M_1)_{\rm III}$ by swapping processes II and III. The latter process is within the Lorentzian regime of spacetime and results in the quantum measuring system $M_2$. Therefore, we conclude that the objective result is also $M_2$.

In this article, we approach the structure of the quantum measuring system in the Euclidean regime of the classicalized holographic tensor network from the perspective of integrated information theory. As a result, we obtain the following picture of the Euclidean regime. First, there are complexes, which are independently accompanied by the level and structure of experiences, determined from the full transition probability matrix of the whole particle system. Second, the cause-effect structures of independent complexes would be directly entangled by the physical information propagation in the whole particle system. Finally, distinct full transition probability matrices of the whole particle system that exhibit the maximum cause-effect power may coexist.

It is a sort of ultimate question to examine the continuity of a quantum measurement subject theoretically and has not yet been resolved within a scientific framework.In this article, we approach this question and argue that the continuity of a quantum measurement subject follows as a fundamental consequence of the holographic principle after the classicalization of the quantum state of the bulk space.

In quantum mechanics without application of any superselection rule to the set of the observables, a closed quantum system temporally evolves unitarily, and this Lorentzian regime is characterized by von Neumann entropy of exactly zero. In the holographic theory in the classicalized ground state, we argue that the unitary real-time evolution of a non-relativistic free particle with complex-valued quantum probability amplitude in this Lorentzian regime can be temporally analytically continued to an imaginary-time classical stochastic process with real-valued conditional probability density in the Euclidean regime, where the von Neumann entropy of the classicalized hologram and the information of a particle trajectory acquired by the classicalized hologram are positive valued. This argument could shed light on the Euclidean regime of the holographic Universe.

This paper aims to produce freshwater from saline water with the help of solar still. Different solar Wick materials still absorb the sunlight and convert the heat energy, such as black sheer mesh fabric, light black cotton fabric, light jute fabric, black velvet fabric, and 4 mm thick sponge sheet. The Wick materials sheets were wholly immersed in the saline water covering the total still basin area. The net basin horizontal active area of the solar still is 0. 48 m² , and the glass cover’ s tilted angle was fixed at 36º . From this arrangement, it has been found that by the use of various Wick materials, the productivity rate differs from each other, and among these Wick materials, light black cotton is the most effective Wick material for solar still productivity increment. The pH value measures the final quality of the freshwater.

For desalinating seawater and brackish water, a basic and inexpensive device known as a solar still is used. The limited amount of freshwater output that can be obtained from a solar still is its primary flaw, which limits its global use and applicability. The improvement of a solar still's freshwater output is the main goal of this research. Two identical single slope solar stills are created for this purpose, and one of them is changed by adding rectangular aluminium fins and a bamboo cotton Wick to the still basin. This modified still is called. The other still that hasn't been altered is known as a standard still. In this experimental study, Kurukshetra, India (29.96°N, 76.87°E) weather conditions are used to evaluate both stills. At varying water depths of 1 cm, 2 cm, and 3 cm, the performance of the modified still and the conventional still are concurrently compared. According to experimentation's findings, 1 cm of water depth is where both stills' daily productivity and optimum water temperature are attained. The daily productivity of the solar still improved by about 19% when bamboo cotton Wick was spread over the rectangular fins in the still basin.
