Welcome to My Academic Blog

Introduction

Welcome to my academic blog! I’m Wenjie Xu, currently a Ph.D. candidate at the Institutes of Science and Development, Chinese Academy of Sciences.

About My Research

My research primarily focuses on the following areas:

1. Critical Infrastructure Risk Management - Studying risk propagation mechanisms in energy and transportation networks
2. System Resilience Assessment - Developing data-driven resilience evaluation methods
3. Emergency Decision Optimization - Optimal recovery strategies under resource constraints

Mathematical Formula Example

This blog supports KaTeX mathematical formula rendering. For example, Bayes’ theorem can be expressed as:

$$P(A|B) = \frac{P(B|A) \cdot P(A)}{P(B)}$$

Inline formulas are also supported, such as $E = mc^2$.

Code Example

import numpy as np
import networkx as nx

def calculate_resilience(G: nx.Graph, failure_nodes: list) -> float:
    """Calculate network resilience after node failures"""
    G_copy = G.copy()
    G_copy.remove_nodes_from(failure_nodes)

    if len(G_copy) == 0:
        return 0.0

    largest_cc = max(nx.connected_components(G_copy), key=len)
    return len(largest_cc) / len(G)

Future Plans

In this blog, I will share:

• Academic research progress and paper reviews
• Technical tutorials and tool recommendations
• Thoughts on complex systems and risk management
• Personal reflections

Looking forward to connecting with you!
