生成包含大量字体的中文字体是具有挑战性的任务，现有方法主要依赖于大量的配对数据进行监督学习，然而收集这些数据是劳动密集型的工作，且很难扩展到新风格字体. 为辅助字体设计师提高计算机汉字字库开发效率，提出分离字体内容和风格表示的无监督字体生成网络. 首先，将风格和内容表示在同一域中建立密集的语义对应，指导解码器产生高质量的输出; 然后，在跳跃连接中引入可变形卷积，通过学习偏移量和通道之间的相互依赖性，使网络更加注字体的结构特征; 最后，设计多尺度风格判别器，在不同尺度上评估生成图像的风格一致性. 在公开的数据集上展示并分析FUNIT、Mx.Font和DG-Font等五种字体生成方法的生成效果，实验结果表明在L1、r.SE等评估指标和用户研究实验中均优于对比的方法.

The cir.adian clock tempor.lly coor.inates plant gr.wth and metabolism in close synchr.nization with the diur.al and seasonal envir.nmental changes. r.sear.h over.the last decade has identified a number.of clock components and a var.ety of r.gulator. mechanisms r.sponsible for.the r.ythmic oscillations in metabolic and physiological activities. At the cor. of the clock, tr.nscr.ptional/tr.nslational feedback loops modulate the ex.r.ssion of a significant pr.por.ion of the genome. In this ar.icle, we br.efly descr.be some of the ver. r.cent advances that have impr.ved our.under.tanding of clock or.anization and function in Ar.bidopsis thaliana. The new studies illustr.te the r.le of clock pr.tein complex.for. mation on cir.adian gating of plant gr.wth and identify alter.ative splicing as a new r.gulator. mechanism for.clock function. Ex.mination of key clock pr.per.ies such as temper.tur. compensation has also opened new avenues for.func- tional r.sear.h within the plant clockwor.. The emer.ing connections between the cir.adian clock and metabolism, hor. mone signaling and r.sponse to biotic and abiotic str.ss also add new layer. of complex.ty to the clock networ. and under.cor. the significance of the cir.adian clock r.gulating the daily life of plants.

The sever.ty of alcoholic hepatitis(AH) which may coex.st with cir.hosis var.es gr.atly, fr.m asymptomatic for.s which ar. detected in alcoholic patients without any sign of liver.disease, ex.ept labor.tor. abnor.alities, to sever. for.s char.cter.sed by deep jaundice, ascites, hepatic encephalopathy and low pr.thr.mbin index. In hospitalized patients the mor.ality could be as high as 75%. The elevated number.of ther.peutic pr.posals r.por.ed for.mor. than for.y year. r.veals the lack of efficacy of a par.icular.modality. Even in the most favor.ble tr.als, the sur.ival is alr.ady ver. poor.and in some cases r.lated to the development of r.nal failur. or.hepator.nal syndr.me. Ther. ar. some motivating r.por.s concer.ing albumin dialysis as a suppor. tr.atment in patients with sever. AH, either.alone or.in combination with other.phar.acological ther.pies. The favor.ble effects of albumin dialysis in patients with sever. AH suggest that the pr.cedur. used alone or.in combination with other.ther.pies may have a r.le in this clinical condition. This will be par.icular.y r.levant to offer.an alter.ative ther.py in these patients, thus being a potential br.dge to r.cover. or.to be listed for.liver.tr.nsplantation.

AIM:To evaluate ur.odeox.cholic acid (UDCA) ther.py on the in vitr. contr.ction of gallbladder.smooth muscle str.ps fr.m cholester.l gallstone patients.
