    Efficient Headroom Allocation with Two-level Flow Control for Lossless Datacenter Networks

    IEEE/ACM Transactions on Networking, September 2024 (under review)

    In datacenters, lossless network is very attractive as it can achieve ultra-low latency. To avoid buffer overflow, PFC-enabled switches need to reserve some buffer as headroom, which is for absorbing in-flight packets during the delay for backpressure messages to take effect. However, the current static and queue-independent headroom allocation scheme is inherently inefficient in solving this problem. In light of this, we propose Dynamic and Shared Headroom allocation scheme (DSH), which dynamically allocates headroom to congested queues and enables the allocated headroom to be shared among different queues.

    Hydrocephalus Diagnosis Support System Based on the UNet Model
    Chengzhen Liu, Boxuan Hu*, Lifan Gu
    Computer Software Copyright, June 2024

    The diagnosis of pediatric hydrocephalus traditionally relies on radiological examinations, with Evans' Index as a key severity indicator. To address the time-consuming and subjective nature of manual measurements, we propose an automated diagnostic approach using deep learning. Our enhanced U-Net model performs lateral ventricle segmentation and Evans' Index measurement from brain imaging, incorporating dense connectivity and attention mechanisms. Results demonstrate high segmentation accuracy and strong correlation with manual measurements, validated through clinical cross-validation. This automated solution offers efficient and objective diagnostic support, showing promise for broader medical imaging applications.
