Design and Implementation of Network Monitoring System based on Rule Database [PDF]
, 1900 随着互联网技术的不断发展，网络安全问题在现代社会中不断凸显，从最初的简单口令猜测等到现在的漏洞扫描、缓冲区溢出等，到后来的通过伪造IP截取网络包等，网络攻击也处在不断发展的进程中。现如今，网络安全问题是不容忽视的，个人的财产或国家的经济发展、安全保障都可能因为网络中的不安全因素而受到巨大的影响，所以网络安全问题是互联网发展中不可回避、不可小觑的问题。 本文从网络监控中比较完善的入侵检测系统入手，分析其原理和体系结构，实现一个Linux下网络监控系统。在具体实现方面，主要采用对网络中的数据进行协议分析 ...

Anomaly detection model based on multi-grained cascade isolation forest algorithm [PDF]
, 2019 The isolation-based anomaly detector,isolation forest has two weaknesses,its inability to detect anomalies that were masked by axis-parallel clusters,and anomalies in high-dimensional data.An isolation mechanism based on random hyperplane and a multi ...

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
International Journal of Applied Linguistics, EarlyView.ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, EarlyView.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis
Veterinary Dermatology, EarlyView.ABSTRACT Background Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears.

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Metal oxide semiconductor‐supported noble metal nanoparticles are common sensing materials for gas sensors. However, the large size and their tendency to migrate at high temperatures often lead to inferior sensing sensitivity and stability. Herein, a salt‐assistant strategy is developed to prepare fully‐exposed Ir clusters on SnO2 nanorods ...
