Proposed mathematical equation for evaluating the residual punching shear capacity of high-performance concrete slabs after being subjected to impact loading Al-Zahid, Ali Adnan The research investigates the validity of high-performance concrete slabs under punching shear after they are exposed to impact load. The importance of this study lies in opening new avenues for researchers regarding slabs subjected to impact loading, specifically addressing whether they can be repaired and strengthened or are more likely to require reconstruction. The experimental program consists of eight slabs with different parameters tested under the same impact loading, and then the punching shear capacity is evaluated. One of these slabs was reinforced by traditional reinforcement, while the other specimens discussed different techniques designed to find alternative modified methods to resist punching shear. Finally, the suggested empirical formula predicts the value of punching shear for high-performance concrete slabs that suffer from impact load. The accuracy of the suggested equation reached 90.5% from experimental results.

Weaker forms of open sets in Pythagorean Fuzzy nano topological spaces and its application using entropy measure Deivanayagi, P.; Tamilselvan, S.; Vadivel, Appachi In this paper, we introduce a Pythagorean Fuzzy nano M-open set which is the union of Pythagorean Fuzzy nano δP-open sets and Pythagorean Fuzzy nano θS-open sets in Pythagorean Fuzzy nano topological spaces. Also, we discuss about near open sets, their properties and examples of a Pythagorean Fuzzy nano M-open set. Moreover, we investigate some of their basic properties and examples of Pythagorean Fuzzy nano M-interior and M-closure in a Pythagorean Fuzzy nano topological spaces. One real life applications, one on better way of shopping, based on this proposed entropy measure are also illustrated.

q*-Rung orthopair neutrosophic subspaces and nodec spaces Shyamaladevi, Vaiyanan; Revathi, Govindasamy Krishnamoorthy The study explores the concept of q*-rung orthopair neutrosophic topological spaces, beginning with foundational results on q*-rung orthopair neutrosophic sets. It defines subspace topology within these spaces and analyzes various properties, particularly q*-rung orthopair neutrosophic nodec spaces. These are examined under the condition that every q*-rung orthopair neutrosophic nowhere dense subset is q*-rung orthopair neutrosophic closed. Additionally, as specific examples of nodec spaces, the study investigates submaximal spaces and q*-rung orthopair neutrosophic doors. Relevant characteristics and behaviors are methodically examined. Interestingly, it shows that a q*-rung orthopair neutrosophic nodec space can be obtained by combining two discontinuous q*-rung orthopair neutrosophic closed and q*-rung orthopair neutrosophic dense (or open) spaces. Furthermore, the way these nodec spaces behave under different operations is examined.

Fractional-order modeling of Zika virus transmission: analysis and numerical simulations Shah, Kunjankumar N.; Parmar, Jayashree; Patel, Jaydev S.; Patel, Himanshu C. This study presents a novel mathematical framework for modeling Zika virüs transmission dynamics within human populations and between humans and mosquitoes, utilizing a fractional-order Caputo derivative. The study establishes the system’s feasibility region, determines equilibrium points, and analyzes their stability. The existence and uniqueness of the solution are proven using fixed-point theory, and solutions are approximated via the fractional natural decomposition method. A key novelty of this study lies in the comparative analysis of fractional-order and integer-order models, highlighting how fractional derivatives provide greater modeling flexibility and better capture memory effects in disease progression. The numerical simulations demonstrate the significant influence of fractional derivatives on system behavior, illustrating differences in the rate of infection spread and disease persistence compared to integer-order models. This fractional calculus approach offers valuable insights into the complex dynamics of Zika virus transmission. Importantly, this study explores how fractional-order modeling can enhance existing control strategies against Zika virus outbreaks, providing a more refined framework for evaluating intervention measures and improving public health decisionmaking.
