Identifying New Classes of Financial Price Jumps with Wavelets

Research Report on Identifying New Classes of Financial Price Jumps Using Wavelets Academic Background Price jumps in financial markets refer to significant price fluctuations occurring within an extremely short period, typically caused by exogenous factors (such as sudden news) or endogenous factors (internal market feedback mechanisms). Distingui...

Out-of-Distribution Generalization via Composition: A Lens Through Induction Heads in Transformers

Study on Out-of-Distribution Generalization and Composition Mechanisms in Large Language Models Paper Background In recent years, large language models (LLMs) such as GPT-4 have demonstrated remarkable creativity in handling novel tasks, often solving problems with just a few examples. These tasks require models to generalize on distributions diffe...

Adaptive Quantized Control for a Class of Hysteresis Nonlinear System with Irregular Constraints and Its Application to Piezoelectric Positioning Stage

Adaptive Quantized Control Research for Hysteresis Nonlinear Systems in Piezoelectric Positioning Stages Background Introduction In modern high-precision positioning systems, smart materials (such as piezoelectric ceramics) are widely used in micro/nano manufacturing and soft robotics due to their excellent performance. However, the inherent hyster...

Exoskeleton-Assisted Stance and Kneeling Balance and Work Task Evaluation in Construction

Balance and Task Evaluation of Construction Workers Assisted by Knee Exoskeletons Background Introduction Construction workers face serious safety and health risks in hazardous working environments, especially when working at heights. Prolonged standing and kneeling postures can lead to knee injuries, musculoskeletal disorders, and visual disturban...

Automated Strategy for Tissue Analysis in Anatomic Pathology: Fiducial Marker Integration and Multisurface Tissue Comparison

Automated Strategy for Tissue Analysis in Anatomic Pathology: Fiducial Marker Integration and Multisurface Tissue Comparison Background Introduction In anatomic pathology laboratories, many processes still rely on manual operations, especially in the preparation and processing of paraffin-embedded tissue blocks (PETBs). Manual operations not only l...
