从《一千零一夜》开始

当代文坛 2024年第1期 52-60页

1.《一千零一夜》,博尔赫斯认为,这是世界上最好的书名。“一千夜”就是“永远”,“一千零一夜”就是“比永远还要远”,就是“永恒”。所以,英文里表达“永恒”用的就是“forever and a day”(永远零一天)。在写作意义上,“一千零一夜”让整体变成个体,让模糊变得具体,让整体与个体相融,让模糊与具体交织。“一千零一夜”也让每一个夜晚变成“这一个”夜晚,让每一个故事变成“这一个”故事。

一前不久看一篇评论家综论,提及“70后”的创作,认为这一代作家执念于细节的营造,同时也因过于拘泥细节,而未获取足够开阔的视野,也未抵达更为幽深的人性观照。我读罢这一段,脑子迅速扫描我熟悉的一些“70后”作家及创作。作为一个群体,我们起初似乎都排斥“70后”这样笼统粗率的命名,但随着写作的推进,这一代人整体步入中年,“70后”的指称也一直未有更好的替代,慢慢我们开始接受、认领。毕竟我们不能否认,我们就是一代人。起初感觉这样的命名什么也没说,慢慢觉得它把什么都说了,甚至具有某种预言性质:你们只是整体清晰而个体贫弱的一代人。所以,“70后”老早又被冠名为“夹缝的一代”。相对于晚一点的“80后”,“70后”的个人面孔相对模糊,而“80后”个人仿佛自带一种横空出世的禀赋,比如早一点的韩寒,稍晚的双雪涛,近几年的班宇。

Anisotropy is a significant and prevalent characteristic of materials, conferring orientation-dependent properties, meaning that the creation of original symmetry enables key functionality that is not found in nature. Even with the advancements in atomic machining, synthesis of separated symmetry in different directions within a single structure remains an extraordinary challenge. Here, we successfully fabricate NiS ultrafine nanorods with separated symmetry along two directions. The atomic structure of the nanorod exhibits rotational symmetry in the radial direction, while its axial direction is characterized by divergent translational symmetry, surpassing the conventional crystalline structures known to date. It does not fit the traditional description of the space group and the point group in three dimensions, so we define it as a new structure in which translational symmetry and rotational symmetry are separated. Further corroborating the atomic symmetric separation in the electronic structure, we observed the combination of stripe and vortex magnetic domains in a single nanorod with different directions, in accordance with the atomic *** manipulation of nanostructure at the atomic level introduces a novel approach to regulate new properties finely, leading to the proposal of new nanotechnology mechanisms.

Cardiac rehabilitation, a comprehensive exercise-based lifestyle and medical management, is effective in decreasing morbidity and improving life quality in patients with coronary heart disease. Endothelial function, an irreplaceable indicator in coronary heart disease progression, is measured by various methods in traditional cardiac rehabilitation pathways, including medicinal treatment, aerobic training, and smoking cessation. Nevertheless, studies on the effect of some emerging cardiac rehabilitation programs on endothelial function are limited. This article briefly reviewed the endothelium-beneficial effects of different cardiac rehabilitation pathways, including exercise training, lifestyle modification and psychological intervention in patients with coronary heart disease, and related experimental models, and summarized both uncovered and potential cellular and molecular mechanisms of the beneficial roles of various cardiac rehabilitation pathways on endothelial function. In exercise training and some lifestyle interventions, the enhanced bioavailability of nitric oxide, increased circulating endothelial progenitor cells(EPCs), and decreased oxidative stress are major contributors to preventing endothelial dysfunction in coronary heart disease. Moreover, the preservation of endothelial-dependent hyperpolarizing factors and inflammatory suppression play roles. On the one hand, to develop more endothelium-protective rehabilitation methods in coronary heart disease, adequately designed and sized randomized multicenter clinical trials should be advanced using standardized cardiac rehabilitation programs and existing assessment methods. On the other hand, additional studies using suitable experimental models are warranted to elucidate the relationship between some new interventions and endothelial protection in both macro-and microvasculature.

东汉前期新设兰台,皇帝征召兰台之官。兰台文雄会聚,成为一个职能清晰的官方文艺机构。兰台文人用史、赋、颂、传记述东汉获得天命、功致太平的历程,由此形成一系列“文”的实践活动。班固等在兰台撰著《世祖本纪》,编织光武帝事迹,彰显其创业之功,确立开国史叙述;兰台文人撰著多篇“都赋”,以迁都洛阳隐喻东汉受命,批评西汉之承秦,凸显“汉历中绝”,建构“建武革命”的观念;文人创作《哀牢传》《神雀颂》等,染“万夷宾服”,暗喻东汉的统治区域达到前所未有之广阔。文人作“汉颂”,比拟《周颂》,传达古今同况、功成德洽之义。这一系列文章实践是明、章时代一场重要的政治文化工程,是东汉王朝重建合法性的自我表达。
