A Comparative Forecasting Framework for Weekly VIX Prediction Based on Statistical and Machine Learning Models with Bayesian Optimization

Accurate forecasting of the CBOE Volatility Index (VIX) is an important problem in financial risk modeling and time-series prediction due to its role as a widely used indicator of market uncertainty. This study proposes a comparative forecasting framework for weekly VIX predictio...

Computational Prediction of Pressure-Responsive Luminescence of a D-π-A Compound with Boron–Nitrogen Motifs

Abstract Under pressure, organic luminescent materials typically display peculiar and fascinating photoluminescence behaviors. Elucidating the luminescence mechanism under pressure is the key to the rational design of piezochromic materials. Here, we carried out an in-depth theor...

Therapeutic Cancer Vaccines: Classification, Mechanisms, Challenges and Future Perspectives

BACKGROUND: With the rapid advancements in oncology, immunology, and molecular biology, immunotherapy has emerged as a cornerstone of anti-tumor treatment, complementing traditional modalities such as surgery, radiotherapy, and chemotherapy. Therapeutic cancer vaccines are a prom...

Templated growth of phase-pure two-dimensional perovskite for durable solar cells

Abstract The impure phase in typical solution-processed two-dimensional/three-dimensional (2D/3D) perovskite heterostructures limit the performance and stability of perovskite solar cells. We overcome this limitation through a templated growth strategy utilizing excess lead iodid...

Cow Behavior Recognition Method Based on Multi-Source Perceptual Information Fusion

This study proposes a multi-source perceptual information fusion method to improve the accuracy and stability of dairy cow behavior monitoring. Existing machine vision approaches are often affected by lighting conditions, occlusion, and complex cowshed environments, while single...

Utilization of traditional medicine for childhood illness and its associated factors among parents of children under five years in Karat Zuria Woreda, Konso, South Ethiopia, 2024: an explanatory sequential design

Traditional medicine remains a primary source of healthcare in many developing countries. In Ethiopia, more than 80% of parents report using traditional remedies for their children. While these practices are culturally embedded, improper use can worsen childhood illnesses and cau...

Culture Shapes the Neural Functional Alteration and Its Development in Children With Dyslexia: A Cross‐Linguistic Meta‐Analysis

How culture shapes brain functional alteration and its development remains poorly understood in dyslexia (DD). Hereby, we conducted a meta-analysis comparing brain activation in children across Chinese (logographic), English (deep alphabetic), and German (shallow alphabetic) writ...

Exploring the Mediation of EFL Learners' Perceptions of Teacher Fairness on the Association Between Learning Climate and Self‐Efficacy

ABSTRACT Self‐efficacy refers to the learners' beliefs in their abilities to adjust their learning, which can lead to learners' educational success and motivation, and thus, is important within the learning procedure. The learning climate has a vital effect on the educational per...
