In the present work, a treatment technique for trigeminal neuralgia (Tn) using LInAC radiosurgery is shown. The technique is based on the optimization of ten static arcs in such a way as to minimize the overlapping of the treatment fields with the brainstem. We will call this technique brainstem-optimized (BO). The results are compared with another technique described in the literature known as a virtual cone (VC). The comparison of dosimetry results that have been carried out essentially shows that the doses in the brainstem V12Gy-brainstem, D0.5cm3-brainstem and D0.035 cm3-brainstem are lower in the BO versus VC technique, and with the parameters V50% (whole brain) and V12Gy-cerebrum higher in BO versus VC. Our goal is to keep the dose to the brainstem as low as possible and, if possible, at most between 12 Gy and 15 Gy. The BO technique meets our purposes and is considered clinically acceptable at our institution.

开发还原二氧化碳生成燃料和有价值化学品的低成本、非金属半导体光催化剂,是减少二氧化碳浓度的一种有效方案.本工作通过简单的静电吸附方法成功地将黑磷量子点(BPQDs)分散在石墨相氮化碳(g-C_3n_4)载体上,成功制备了BP@g-C_3n_4复合材料,并对其在紫外-可见光激发下光催化还原CO_2的性能进行了研究.电化学表征,瞬态吸收光谱和荧光光谱数据表明BPQDs的负载提高了g-C_3n_4的载流子分离效率.在氙灯的照射下,与g-C_3n_4(CO的生成速率为2.1μmol g^(-1)h^(-1))相比,BP@g-C_3n_4复合材料光催化还原CO_2活性显著提高(当BPQDs的负载量为1 wt%时,CO的生成速率为6.54μmol g^(-1)h^(-1)).本工作发展了一种新型的可还原CO_2的非金属基光催化剂.

构造了具有良好解析性和幺正性的共振态X(3872)衰变谱,能够定义衰变反应X(3872)→D*0D0+c.c.的分支比,而只需要多研究另外一个衰变,比如说X(3872)→π+π-J/ψ(1 S)衰变,这表明构造谱是筛选共振态X(3872)模型的有效工具.之后讨论了共振态X(3872)是粲偶素c珋c=χ0c1(2P)的情形,此时它处在D*D0的阈上.根据由粲偶素χc1(2P)的质量的势能模型的预言解释了共振态X(3872)的质量偏移.这个势能模型是依据衰变产物D*D+c.c.的中间态计入共振态X(3872)的质量的贡献而构造的.这使得我们能够研究共振态X(3872)和衰变道D*0D0的耦合常数,X(3872)*→D 0D0+c.c.的衰变分支比以及共振态X(3872)衰变到所有不含D*0D0+c.c.的过程的分支比.预言了一个共振态X(3872)通过双胶子衰变的重要常数.
