A system which solves simple algebraic equations and classifies the types of simultaneous equations. Preprocesses questions and numerical values will be mapped to an equation and output the answer.

If your Word equation is not converting to professional format, you’re not alone. Some users have reported that equations typed in Microsoft Word on a Windows 11/10 PC fail to switch from linear text ...

The problem of determining whether a word equation admits a solution whose lengths belong to some semilinear set is fundamental to the theory of string-solving. Despite this and connections to Hilbert ...

If equations in Microsoft Word aren’t switching to the professional math layout, it’s usually a formatting mismatch or a temporary glitch. Follow these quick, safe steps in order, and stop when the ...

本研究揭示了活性氧物种(ROS)在美洲黑杨木质部发育中的关键作用。研究人员通过对比分析速生型(Wimco-109)和慢生型(Wimco-83)克隆株系发现，超氧阴离子(O2•?)促进生长而H2O2导致木质化增强。研究证实NADPH氧化酶(NOX)活性差异调控ROS平衡，为造纸工业选育低木质素 ...

为解决电化学发光(ECL)传感中H2O2与溶解氧(O2)的竞争反应难题，研究人员开发了氮掺杂分级多孔碳负载单原子钴位点(Co?NC SAs)作为共反应加速剂。该材料选择性激活H2O2产生活性氧，显著增强鲁米诺ECL信号，并构建三通道传感器阵列实现五种塑化剂的高灵敏度检测 ...
