ABSTRACT Analysing learners' facial expressions during learning and exploring their learning processes and emotional changes are of great significance for assisting teachers' teaching and promoting smart education. In co...

Los bosques tropicales almacenan grandes cantidades de carbono en su biomasa, y por ello juegan un papel determinante en el ciclo global de este elemento. Las variables biofísicas determinan la capacidad de almacenamien...

Holograms which reconstruct the transverse profile of light with complex-amplitude information have demonstrated more excellent performances with an improved signal-to-noise ratio compared with those containing amplitude...

IntroductionWeather classification plays a crucial role in applications such as environmental monitoring, disaster management, and smart city infrastructure. Accurate and efficient classification of weather conditions fr...

This paper expounds an exploratory study on the connections between Amartya Sen's capability approach and epistemic proceduralism focused on the measurement of poverty. The study describes the general features of Sen's a...

With high hardness, high thermal and chemical stability and excellent optical performance, hard materials exhibit great potential applications in various fields, especially in harsh conditions. Femtosecond laser ablation...

This paper presents a dual-polarization multiplexed optical phased array (OPA) implemented on a 220 nm silicon-on-insulator (SOI) platform, enabling continuous beam steering across TE and TM modes. While effectively gu...

Abstract Background Adequate housing is a basic human right. The many millions of people experiencing homelessness (PEH) have a lower life expectancy and more physical and mental health problems. Practical and effective ...

Internal auditing is increasingly recognized as a vital mechanism for fostering transparency and accountability within the public sector, particularly in emerging economies like Vietnam. However, the rapid onset of digit...

The purpose of this work is, first, to present a fast and accurate technique to compute Boltzmann-averaged values of the quantum-chemical 13C chemical shifts for each amino acid in oligopeptides, demonstrated here by an ...

"Several works have addressed the issue of obtaining a six degree of freedom (6DOF) capable multirotor. However, the capability of keeping full control in the case of a total failure in one of the rotors has not yet been...

Abstract Conventional manipulators with rigid structures and stiffness actuators have poor flexibility, limited obstacle avoidance capability, and constrained workspace. Some developed flexible or soft manipulators in re...

We demonstrate a versatile heterogeneous integration platform unifying III–V gain with thin-film lithium niobate (TFLN) photonic circuits to create high-performance lasers with integrated functionality. This breakthrou...

To meet the growing demand for photonic integration and device miniaturization, planar diffractive Fresnel zone plates (FZPs) are widely applied in integrated optical systems. However, challenges remain in fabricating FZ...

We report a coherent layer-by-layer build-up of high-order harmonic generation (HHG) in artificially stacked transition metal dichalcogenides (TMDC) crystals in their various stacking configurations. In the experiments, ...

A parabolic potential that confines charge carriers along the growth direction of quantum wells semiconductor systems is characterized by a single resonance frequency, associated to intersubband transitions. Motivated by...

Organometallic perovskite single crystals have been considered one of the most promising candidates for photodetection applications, owing to their grain-boundary-free structure and improved optoelectronic properties. Ho...
