Gate-controlled optical bistability via tunable self-action feedback in a semiconductor quantum dot–graphene nanodisk hybrid

We theoretically examine how electrostatic gating can tune the steady-state response of a semiconductor quantum dot (SQD)-graphene nanodisk hybrid between monostable and bistable regimes. The model combines the optical Bloch dynamics of a driven two-level SQD with a gate-dependen...

Packing Chromatic Number of Graph Families Constructed from the Fan Graph

Packing coloring is particularly sensitive to graph distances, since even a simple structural modification may change whether a color can be reused. This paper investigates the packing chromatic number of several constructions derived from the fan graph, namely the subdivision fa...

Sources, classification, analytical detection, and mitigation strategies for palm oil contaminants

An overview of contaminant fingerprinting and traceability of crude palm oil products is introduced. The review focuses on process contaminants, mineral oil hydrocarbons, environmental contaminants, agricultural residues, and packaging/contact migrants. The formation mechanisms o...

Computationally guided multi-epitope vaccine design targeting oncoprotein BZLF1, EBNA1, LMP1, and LMP2 for of EBV associated gastric cancer

Abstract Background Epstein–Barr virus (EBV)–associated gastric cancer (EBVaGC) is distinct molecular subtype of gastric cancer for which effective preventive and targeted therapeutic strategies remain limited. This study aimed to design and evaluate multiepitope vaccine candidat...

Remodeling and Application of Stock Option Price Based on Skewed Laplace Distribution Approach

This paper proposed a new model to price a stock option based on the Skewed Laplace distribution approach (SLOP). The approach was considered to provide a better option price than Black Scholes Option Price (BSOP) because Skewed Laplace distribution (SL) has a shape parameter tha...

Spatio-Temporal Forecasting and Continuous Spatial Reconstruction of Fire Radiative Power Using Sequential GSTARX-IDW and Ordinary Kriging

This study presents a sequential hybrid spatio-temporal forecasting framework combining the Generalized Space-Time Autoregressive with Exogenous Variables (GSTARX-IDW) model and Ordinary Kriging (OK) to model and map weekly Fire Radiative Power (FRP) dynamics in West Kalimantan f...

Profiling Undergraduate EFL Learners’ Use of AI Tools: A Person-Centered Analysis of TAM and SRL

The effectiveness of AI tools in EFL learning depends not only on technology acceptance but also on learners’ self-regulated learning (SRL). However, prior research often treats learners as homogeneous and overlooks distinct user profiles. This study integrates the Technology Acc...

Global research landscape of transformative learning in pre-service teacher education: A Scopus-based bibliometric and science-mapping analysis

<ns5:p>Background Transformative learning explains changes in pre-service teachers’ frames of reference, yet previous mapping studies have examined the theory broadly, within higher education, or in specific domains such as sustainability. This study maps the development, contrib...

Decentralised Community-Based Hub-Intermediary-Spoke Model for Rapid Cardiac Ultrasound Triage for Early Heart Failure Detection: Findings From the Heart2Miss Initiative

Abstract Aims To evaluate the feasibility and system-level performance of Heart2Miss, a decentralised community-based triage model deploying AI-powered point-of-care ultrasound (AI-POCUS) via a hub-intermediary-spoke approach in diabetes primary care for early heart-failure (HF)...
