A wideband high-isolation four-port MIMO antenna with orthogonal diversity and DGS for 5G sub-6 GHz applications

Abstract The 5G NR sub-6 GHz bands n77 (3.3–4.2 GHz) and n78 (3.3–3.8 GHz) are widely used for modern 5G communication systems due to their balanced coverage and capacity. This work presents a compact wideband four-port MIMO antenna employing orthogonal diversity and defected gro...

Elucidating the role of noble metals in Ag- and Pd-modified TiO2 visible-light photocatalysts: Theoretical validation of experimental evidence

A combined experimental–theoretical understanding of the noble metal-modified TiO 2 photocatalysis for environmental remediation remains relatively unexplored. This study investigates the influence of silver (Ag) and palladium (Pd) modifications on the visible-light photocatalyti...

AQbD Driven RP-HPLC method for estimating rizatriptan benzoate and meloxicam: integrating green and blue analytical approaches

The present study aimed to develop and validate a robust, stability-indicating RP-HPLC method for the simultaneous determination of Rizatriptan Benzoate and Meloxicam using an Analytical Quality by Design approach integrated with green analytical principles. A central composite d...

Four-port triple notched wide-band MIMO antenna and verification by theory of characteristics mode for multiple applications

Abstract This paper presents a compact four-port multiple-input-multiple-output (MIMO) antenna featuring a triple notched-band characteristic for wideband, multiple applications. The single-element antenna is systematically developed and analyzed using the Theory of Characteristi...

A bibliometric study of social isolation and biomarkers of ageing

Abstract Research on social isolation suggests that psychosocial factors are not only associated with adverse mental health conditions but also associated with various neurobiological and immunological processes. The physiological mechanisms underlying the health effects of socia...

Behavioural and cognitive determinants of financial loss and mental health deterioration following cybercrime victimisation

Abstract The rapid growth in the use of digital technologies has led to increased exposure to cybercrime, with significant financial and psychological consequences. This study examines the behavioural and cognitive factors that affect cybercrime victimisation and its outcomes. Dr...

Scalable and resilient optical network infrastructure with MAB-driven bandwidth management and DQAE-based anomaly detection

Abstract Recent studies show that global Passive Optical Network (PON) deployments will reach over 1.3 billion subscribers by 2030in Optical Network Unit (ONU) device integration. Despite this, legacy systems suffer from scalability bottlenecks and average latency increments of 1...
