[目的]通过抑制肿瘤坏死因子相关受体2(TNFR2)后观察纳米二氧化硅粉尘对肺泡巨噬细胞的损伤程度,并进一步探索由TNFR2参与的肌醇酶1(IRE1)-C-Jun氨基端激酶(JNK)信号通路在介导肺泡巨噬细胞凋亡中的作用。[方法]将NR8383.1型大鼠肺泡巨噬细胞分为空白对照组、二氧化硅组(50 mg/m L)和抗TNFR2组(在二氧化硅组基础上添加10μg/m L anti-TNFR2抗体),同时每组设立3个平行样,培养24 h后,检测各组肺泡巨噬细胞凋亡水平,IRE1-JNK信号通路相关蛋白(TNFR2、凋亡信号调控激酶1、JNK、激活蛋白1、Caspase12)含量。[结果]空白对照组肺泡巨噬细胞凋亡水平,TNFR2、凋亡信号调控激酶1、JNK、激活蛋白1及Caspase12含量均低于二氧化硅组,抗TNFR2处理后上述指标均较二氧化硅组降低,但仍较空白对照组高。[结论]TNFR2可能在JNK-IRE1信号通路介导的肺泡巨噬细胞凋亡中发挥着重要作用。

The experimental realization of Rydberg dressing technology in ultracold atomic systems provides another superior platform for studying novel states of matter and macroscopic quantum *** this work,based on the mean-field theory,we have investigated the ground-state phases of a two-component Bose–Einstein condensate with Rydberg interaction and confined in a toroidal *** effects of the Rydberg interaction and external potential,especially the Rydberg blockade radius,on the ground-state structure of such a system have been investigated in full parameter *** results show that the Rydberg blockade radius,which can be regarded as another controllable parameter,can be used to obtain a variety of ground-state *** interestingly,it is found that for weak Rydberg interactions,the Rydberg blockade radius breaks the spontaneous rotational symmetry of the system,leading to the formation of a discrete unit cell *** strongly interacting cases,it can be used to realize different orders of discrete rotational symmetry breaking.

采用"铁钛平行分选"工艺对高压辊磨超细碎的-3.2 mm钒钛磁铁矿进行选别实验,研究了强磁选对钛铁矿的分选效果.当磨矿细度为-74μm粒级占80%时,辊压产品选钛给矿的单体解离度较颚破产品高0.58%,辊压产品-19μm+11μm粒级中铁氧化物的单体含量较颚破产品低1.38%.与颚破产品采用"阶段磨矿-阶段分选"工艺相比,"铁钛平行分选"得到的强磁精矿中Ti O2的回收率提高5.11%,-19μm粒级的含量降低2.62%.不同粒级钛铁矿在分选空间中的受力分析表明,当粒度降低时,钛铁矿所受的比阻力急剧增加,而比磁力却有所降低,这增加了钛铁矿颗粒被磁场捕获的难度."铁钛平行分选"能够降低选别过程中微细粒钛铁矿的新生成量,改善钛铁矿的强磁选别效果.

中国有过同性恋的非罪化吗?

1997年新刑法把流氓罪分解为几个罪名,这被认为是"中国同性恋的非罪化"。非罪化和"无受害人犯罪"是有紧密联系的。新刑法修订过程中关于非罪化争论的单向度理解,把非犯罪化主要理解为轻微违警罪的"非罪化"是大大忽视了"非罪化"更广泛的... 详细信息

1997年新刑法把流氓罪分解为几个罪名,这被认为是"中国同性恋的非罪化"。非罪化和"无受害人犯罪"是有紧密联系的。新刑法修订过程中关于非罪化争论的单向度理解,把非犯罪化主要理解为轻微违警罪的"非罪化"是大大忽视了"非罪化"更广泛的内涵。立法者并没有为同性恋正名的意图,同性恋权利的支持者却愿意那么去解读。同性恋社群中把流氓罪的消失看成是一个事件,是因为这个罪里边承载了太多的内容,正是因为有了身体的"感同身受"才有了对于刑法修改的过度诠释,才需要这样一个事件来为身体的后遗症进行治疗。"非罪化"的说法不过体现为同性恋者为了逃避流氓污名,对一些西方的象征性符号进行挪用,运用强势话语来论证同性恋权利的正当性。这是一种话语策略,这种策略可能遮蔽了中国对于同性性行为的"罪"和"非罪"并不敏感的事实,但是对于同性恋者所面临的实际问题来讲,也具有针对性。

Recent years have witnessed numerous technical breakthroughs in connected and autonomous vehicles (CAVs). On the one hand, these breakthroughs have significantly advanced the development of intelligent transportation systems (ITSs);on the other hand, these new traffic participants introduce more complex and uncertain elements to ITSs from the social space. Digital twins (DTs) provide real-time, data-driven, precise modeling for constructing the digital mapping of physical-world ITSs. Meanwhile, the metaverse integrates emerging technologies such as virtual reality/mixed reality, artificial intelligence, and DTs to model and explore how to realize improved sustainability, increased efficiency, and enhanced safety. More recently, as a leading effort toward general artificial intelligence, the concept of foundation model was proposed and has achieved significant success, showing great potential to lay the cornerstone for diverse artificial intelligence applications across different domains. In this article, we explore the big models embodied foundation intelligence for parallel driving in cyber-physical-social spaces, which integrate metaverse and DTs to construct a parallel training space for CAVs, and present a comprehensive elucidation of the crucial characteristics and operational mechanisms. Beyond providing the infrastructure and foundation intelligence of big models for parallel driving, this article also discusses future trends and potential research directions, and the ?S?goals of parallel driving.

We proposed and compared three methods(filter burnup,single energy burnup,and burnup extremum analysis)to build a high-resolution neutronics model for 238Pu production in high-flux *** filter burnup and single energy burnup methods have no theoretical approximation and can achieve a spectrum resolution of up to~1 eV,thereby constructing the importance curve and yield curve of the full energy *** burnup extreme analysis method combines the importance and yield curves to consider the influence of irradiation time on production efficiency,thereby constructing extreme *** three curves,which quantify the transmutation rate of the nuclei in each energy region,are of physical significance because they have similar distributions.A high-resolution neutronics model for ^(238)Pu production was established based on these three curves,and its universality and feasibility were *** neutronics model can guide the neutron spectrum optimization and improve the yield of ^(238)Pu by up to 18.81%.The neutronics model revealed the law of nuclei transmutation in all energy regions with high spectrum resolution,thus providing theoretical support for high-flux reactor design and irradiation production of ^(238)Pu.
