This research presents a novel numerical method for solving a class of complex optimal control problems that feature distributed-order derivatives. The approach leverages the advanced mathematical properties of fractional-order Laguerre wavelets to transform the original continuous-time control problem into a more manageable discrete set of algebraic equations. This transformation is accomplished by utilizing Reimann-Liouville distributed-order operational matrices, which serve as the foundat...
An important therapeutic approach for the treatment of amyloidosis is the rational design of sequence-oriented short peptides, which can prevent the highly ordered cross-β-sheet aggregates formed by misfolded amyloidogenic proteins. In this chapter, we have emphasized human insulin that is a much-studied model protein for amyloidogenesis, because of its well-studied fibrillation pathways. We were able to examine the three delineated aggregation-prone regions (APRs) for targeting insulin aggre...
Drilling is one of the most used machining processes for creating holes in composite materials. However, unlike conventional materials, drilling fiber-reinforced polymer (FRP) composites poses greater challenges due to their heterogeneous and anisotropic nature. In this study, flax-epoxy composites with and without steel wire mesh reinforcement are fabricated and tested using a Taguchi L9 orthogonal array. The effects of spindle speed, feed rate and drill diameter on thrust force, torque and ...
The fundamental vibration frequency of columns decreases with increasing axial compressive load. 1. This paper carries out the free vibration analysis of a beam using the finite element method. The frequencies and mode shapes are determined. The vibration behavior of the beam under axial load is investigated analytically and using the finite element method. The results show that the square of the frequency reduces linearly with an increase in axial load. At the critical buckling load, this fr...

It is based on the Resource Orchestration Theory (ROT) and examines digital financial literacy (DFL) as a mediating variable and digital technology adoption (DTA) as a moderating variabl...
Martian dust storms are one of the most dynamic phenomena on the planet. The dust storms considerably alter several atmospheric characteristics. In this study, the changes in the near-surface atmospheric parameters are observed for two dust storms that occurred during the Martian Year (MY) 36 using the data from the Rover Environmental Monitoring Station (REMS) onboard the Curiosity rover. REMS observations revealed a decline in maximum temperature and an increase in minimum temperature, indi...
Despite offering superior mechanical performance and excellent chemical resistance, thermoset-based fibrous composites come along with a few drawbacks, such as brittle failure, non-biodegradability, difficulty in recycling, and difficulty in joining. These challenges can be addressed by a novel polymer matrix, Liquid Thermoplastic Resin (LTR). Unlike other thermoplastic polymers, LTR offers recyclability, weldability, and easy processing to fabricate composites through Vacuum Assisted Resin T...
Sustainable recycling and reuse of recycled glass fibers are essential for minimizing environmental impact and promoting resource efficiency. This study aims to recycle and reuse the recycled short glass fibers (RSGFs) by chopping and incorporating them in virgin glass fiber-reinforced epoxy composites (VGFECs) at varying concentrations (i.e., 0.1%, 0.3%, 0.5%, and 0.7%) with respect to the weight of epoxy for enhancing the mechanical performance. The flexural performance of RSGFs incorporate...
Silicon holds critical importance as both a technological and structural material. In this study, the melting mechanism of silicon is systematically investigated using molecular dynamics (MD) simulations with the Stillinger–Weber1 (SW) potential, emphasizing free energy analysis. A first-order solid–liquid phase transition is proposed to elucidate silicon’s anomalous behavior. Unlike conventional substances, silicon exhibits a density anomaly: a sharp density drop during quenching and an abru...
Abalone nacre, also known as mother-of-pearl, is a natural composite known for its exceptional combination of strength, toughness, and resistance to impact. This remarkable performance is attributed to its hierarchical ‘brick-and-mortar’ architecture, consisting of hard aragonite (CaCO₃) platelets embedded in a thin biopolymer matrix. Drawing inspiration from this structural motif, the present study focuses on the fabrication and mechanical property evaluation of nacre-mimetic alumina/epoxy c...
This study examines how return migrants’ resort to masstige consumption for the construction of hybrid identities upon returning from metropolitan cities to their Tier 2 and Tier 3 hometowns. While research to date has primarily focused on economic and structural considerations in migration, the symbolic and psychosocial processes of return migration remain an underexplored field. This study, through the branded consumption of masstige products, a rare combination of aspirational appeal with ...
Invisible In-store Technologies (IIST) profoundly influences the purchasing process by creating a seamless, data-driven retail experience that stimulates customers' decision-making at every phase. Interestingly, this transformation of the purchase journey takes place without customers' awareness or explicit consent at the point of action; thus, satisfaction may increase due to convenience or decrease because of unauthorised data access. The study utilised a multi-method qualitative approach t...
The healthcare sector, committed to enhancing public health, paradoxically significantly contributes to environmental degradation through elevated energy consumption, extensive supply chains, and waste production. Healthcare operations worldwide contribute 4–5% of greenhouse gas emissions, positioning them as a primary focus for climate change mitigation efforts. India's rapidly expanding healthcare infrastructure and increasing patient demand present the dual challenge of providing quality c...
Monsoon depressions (MDs) are the significant synoptic systems over the Indian monsoon region, accounting for a substantial fraction (two-thirds) of the seasonal rainfall and associated hazards. Despite their importance, systematic evaluations of MD structure in high-resolution NWP models remain limited. Here, we simulated ten MD cases using an ARW-WRF model (resolution d01 : 13.5, d02 : 4.5 km nested domains) and evaluated storm-centric composites against ERA5 reanalysis and GPM across 24–60...

This paper offers a comprehensive reading of Anuradha Roy’s fiction through the lens of feminist memory studies to trace how memory undergoes an act of counter-history or reclamation of women’s silenced lives. It examines three novels—An Atlas of Impossible Longing (2008), Sleeping on Jupiter (2015), and All the Lives We Never Lived (2018), emphasising that memory is not a recollection of static experiences, but rather it is an affective practice that is always situated in spaces, objects, an...
