AI领域发展迅速，今天看似先进的大模型，几年后可能会被视为落后的小模型。然而，无论技术如何演化，基于第一性原则的结论却能长久有效。在这个报告中，我们将研究如何利用神经网络进行一阶法加速和求解混合整数优化问题，并通过数学推导得到神经网络所必须具备的结构，从而起到简化训练并提升稳定性的作用。
朱卫国教授团队在《Nature Structural & Molecular Biology》发文揭示DNA损伤修复起始阶段染色质乙酰化的调控新机制（图）

2023/10/23
DNA损伤应答与修复经历“进入-修复-恢复” (Access-Repair-Restore，ARR）三个生物学过程。核小体稳态对于DNA损伤应答及信号解除、基因转录瞬时激活与抑制至关重要。单就组蛋白赖氨酸乙酰化来说，乙酰化介导染色质松弛以便DNA修复推进或促进基因转录；去乙酰化则造成致密染色质结构以保护遗传物质不受损失或抑制基因转录，因此染色质松散被认为是DNA双链断裂修复（DSBs）的先决条件。...
