A real-number to molecular structure mapping is a topological index. It is a graph invariant method for describing physico-chemical properties of molecular structures specific substances. In that article, We examined pentacene’s chemical composition. The research on the subsequent indices is reflected in our paper, we conducted an analysis of several indices including general randic connectivity index, first general zagreb index, general sum-connectivity index, atomic bond connectivity index, geometric-arithmetic index, fifth class of geometric-arithmetic indices, hyper-zagreb index, first and second multiple zagreb indices for a four para-lines graphs of linear [n]-pentacene and multi-pentacene.

The aim of this paper is to concentrate on the domain of L_{∞}, L_{p}, and L₁ norms of inequalities and their applications for some special weight functions. For different weights some previous results are recaptured. Applications are also discussed.

<abstract><p>This manuscript involves the new exact solitary wave solutions of fractional reaction-diffusion model using the exp $ \mathrm{(-\ }\varphi \left(\eta \right) \mathrm{)} $-expansion method. The spatial model of fractional form is applied in modeling super-diffusive systems in the field of engineering, biology, physics (neutron diffusion theory), ecology, finance, and chemistry. The findings of miscellaneous studies showed that presented method is efficient for exploring new exact solutions to solve the complexities arising in mathematical physics and applied sciences. The new solutions which are obtained in the form of the rational, exponential, hyperbolic and trigonometric functions have a wide range in physics and engineering fields. Several results would be obtained under various parameters which shows good agreement with the previous published results of different papers. The proposed method can be extended to solve further problems arising in the engineering fields. My main contribution is programming and comparisons.</p></abstract>

During this pandemic, the spreading of hoaxes related to COVID-19 with provocative titles is out of control. Youth organizations as a forum for youth to develop themselves, grow awareness and social responsibility from, for, and by youths were expected to overcome social problems faced by taking an active role in increasing public awareness and vigilance, primarily related to the COVID-19 hoax. Therefore, through this empowerment activity, Desa Bunga-Bunga youth organizations as active internet consumers were expected to increase their ability to think critically in filtering and interpreting information received from the internet and educate others to minimize the existence of hoax-related to COVID-19 in the community. The method of this activity was lecture and discussion of effective communication, hoax, and COVID-19. The participants’ knowledge was assessed by pre-test and post-test. The participants’ understanding of hoax and COVID-19 increased while the communication topic decreased. In conclusion, the participants could sort out hoaxes related to COVID-19.
