基于贝叶斯方法的多Agent强化学习

在多agentss强化学习（MARL）的研究中，很多都是强调MARL算法收敛于期望平衡解。然而，对于标准的强化学习，该过程需要对策略空间的充分探测，而且探测还经常受到惩罚或错失了良机。在多agents系统中，由于agents之间的协作使该问题更加复杂。为此，提出了在MARL用贝叶斯模型来进行最优探测，该模型与标准的RL模型不同，它将对agent的动作是如何影响其它agents的行为进行推理。同时，还给出了如何对最优贝叶斯探测进行处理以获得理想的结果，并通过与其它算法的比较来说明用贝叶斯方法的可行性.

Deoxyribozymes: useful DNA catalysts in vitro and in vivo

Deoxyribozymes (DNA enzymes; DNAzymes) are catalytic DNA sequences. Using the technique of in vitro selection, individual deoxyribozymes have been identified that catalyze RNA cleavage, RNA ligation, and a growing range of other chemical reactions. DNA enzymes have been used in vitro for applications such as biochemical RNA manipulation and analytical assays for metal ions, small organic compounds, oligonucleotides, and proteins. Deoxyribozymes have also been utilized as in vivo therapeutic agents to destroy specific mRNA targets. Although many conceptual and practical challenges remain to be addressed, deoxyribozymes have substantial promise to contribute meaningfully for applications both in vitro and in vivo.

Voltammetric studies on free radicals of lower fatty alcohols

In this work, both generation and reduction processes of the a -radicals of lower fatty alcohols were studied by voltammetry in lower fatty alcohols/peroxydisul- fate/phosphate buffer system. Experimental results showed that such three reactions were successively completed at negative potential on mercury electrode surface: (ⅰ) sulfate radical anion SO₄^.- was generated electrochemically from one-electron reduction of peroxydisulfate ion S₂O₆^2-, (ⅱ) the SO₄^.-oxidized lower fatty alcohols to the corresponding a -radicals and (ⅲ) the a -radicals were reduced in one-electron and one-proton addition to produce their own reduction waves. The apparent free energy ΔrGm of the a -radicals of lower straight-chain fatty alcohols such as methanol, ethanol, propanol, butanol and pentanol obtained were 107.09, 116.74, 122.53, 126.39 and 129.28 kJ·mol/L, respectively. The proposed method is more simple and convenient than the current approaches based on the radical-chain reaction for studying alcohol oxidation.
