Tuning Third-Order Nonlinear Optical Properties in Heterocycle-Dependent Hydrazono-1,3-Diketone Chromophores

Abstract Organic π-conjugated chromophores with tunable electronic structures are promising candidates for nonlinear optical (NLO) and optical limiting (OL) applications. Herein, we report a series of arylhydrazono-1,3-diketones incorporating pyrrole, N-methylpyrrole, thiophene,...

Performance and Environmental Implications of CO2-Cured Nanoengineered Recycled-Aggregate Concrete with Treated Aggregates

Abstract The large-scale use of recycled aggregate (RA) in concrete is hindered by its high porosity and water absorption, which degrade mechanical and durability performance. This study introduces a novel approach that integrates nanocomposite modification and CO 2 curing to unl...

Beyond Linear Paths: Configurations of Networks, Knowledge, and Dynamic Capabilities for Sustainable MSMEs

ABSTRACT Despite extensive research on entrepreneurial business networks (EBNs), knowledge management (KM), and dynamic capabilities (DC), three questions remain theoretically underdeveloped and empirically unexplored in resource‐constrained MSMEs. These concern the integrative m...

A Unified Hybrid Framework for Full-Reference and No-Reference Quality Assessment

Practical deployment of Image Quality Assessment (IQA) systems increasingly demands models that handle both full-reference (FR) and no-reference (NR) scenarios within a single deployable architecture, without compromising accuracy in either mode. Existing frameworks such as DisQU...

Role of continuous wave vs pulse wave and color doppler in identifying arterial perforators of lower limb

Background Accurate identification of arterial perforators is essential for perforator flap surgery. While colour and pulsed wave Doppler provide anatomical and hemodynamic information, continuous wave Doppler is commonly used intra-operatively but lacks validation. Aim To compar...

Thermal and Acoustic Properties of Flax and Hemp Epoxy Bio-Composites Fabricated Using Vacuum-Assisted Resin Infusion Moulding

Synthetic fibre composites deliver high mechanical performance at a substantial energy and carbon cost, motivating a shift to renewable reinforcements. Flax and hemp are credible candidates, but their uptake is constrained by thermal stability and inherent combustibility, and the...

Dynamic responses of rubble mound breakwaters reinforced with geogrid-wrapped slopes and sheet piles under sequential earthquake loading

Rubble mound (RM) breakwaters are widely used to protect coastlines from sea wave actions; however, past seismic events have exposed their vulnerability to catastrophic failure, most often driven by foundation soil instability. Despite the critical importance of this problem, exp...

The Twin Pillars of Financial Stability: Navigating Convergence, Disruption, And Sustainability in Banking and Insurance

Abstract The global financial services sector is in the middle of a fundamental transformation. Banking and insurance—long seen as the twin pillars holding up financial stability—are no longer operating in separate silos. Instead, they are converging into a tightly integrated, te...

The Twin Pillars of Financial Stability: Navigating Convergence, Disruption, And Sustainability in Banking and Insurance

Abstract The global financial services sector is in the middle of a fundamental transformation. Banking and insurance—long seen as the twin pillars holding up financial stability—are no longer operating in separate silos. Instead, they are converging into a tightly integrated, te...

Modeling Nonstationary Extreme Rainfall for Updating Intensity–Duration–Frequency Curves across Indian Cities under Changing Climate

Abstract Nonstationarity in extreme rainfall, driven by an intensifying hydrological cycle under a changing climate, challenges the reliability of conventional stationary intensity–duration–frequency (IDF) curves used in hydrologic design. Analyzing annual and seasonal timeframes...

Preparation of sulphonic acid-functionalized heterogeneous catalyst from cashew nut shell liquid and its application for biomass value addition

Abstract Although cashew nut shell liquid (CNSL) is a well-known biofuel, feedstock for sustainable chemicals and phenolic resins, its use for preparing heterogeneous catalysts by suitable structural modifications remains virtually unexplored. This work reports the preparation of...
