In this paper,we employ the first-principle total energy method to investigate the effect of P impurity on mechanical properties of NiA1 grain boundary(GB).According to"energy",the segregation of P atom in NiA1E5 GB reduces the cleavage energy and embrittlement potential,demonstrating that P impurity embrittles NiA1E5 *** first-principle computational tensile test is conducted to determine the theoretical tensile strength of NiA1E5 *** is demonstrated that the maximum idea/tensile strength of NiA1E5 GB with P atom segregation is 144.5 GPa,which is lower than that of the pure NiA1E5 GB(164.7 GPa).It is indicated that the segregation of P weakens the theoretical strength of NiA1E5 *** analysis of atomic configuration shows that the GB fracture is caused by the interfacial bond ***,P is identified to weaken the interactions between A1-A1 bonds and enhance Ni-Ni bonds.

The self-assembly of sphere-forming triblock copolymers confined between two thin homogeneous surfaces is investigated based on mean-field dynamic density functional theory. The morphologies deviating from the bulk sphere-forming phase are revealed, including cylinders oriented perpendicular to the surface, cylinders oriented parallel to the surface, perforated lamellae and lamellae by varying film thickness and surface field strength. The phase diagram of surface reconstruction is also constructed. By comparing the present phase diagram with the other relevant phase diagram for the cylinder-forming triblock copolymer film, the difference between the sphere-forming and the cylinder-forming triblock copolymer thin film is discussed.

Objective: To investigate the alteration of bcl-2 and bax genes expression in the ischemic myocaradium andthe influence of taurine. Methods: Myocardial ischemia model of rats was induced by ligation of the anterior branchof the left coronary for 4h. All animals were divided into three groups: Sham-operation group. Occlusion group andtaurine group (200mg·kg). The level of myocardial mitochondria Malondialdenyde(MDA)、Superoxide dis-mutase (SOD) and Ca-ATPase activities were determined. The myocardial expression of Bcl-2 and Bax proteinswas detected by immunohistochemistry. Results: Coronary Occlusion of the rats led to significant MDA Content in-

目的研究血管生长因子C(VEGF-C)、血管内皮生长因子受体3(VEGFR-3)水平表达、淋巴管生成与周围型肺腺癌CT表现的相关性。方法选取本院2017年2月至2019年4月收治的52例周围型肺腺癌患者作为研究对象,观察肿瘤病灶大小、形态、有无淋巴结转移等征象,分析周围型肺腺癌的CT征象与VEGF-C、VEGFR-3、淋巴管密度(LMVD)关系。结果周围型肺腺癌VEGF-C阳性表达者,肺门、纵隔淋巴结以增大为主、肿瘤多可见“分叶”征和血管“集束”征,淋巴结多发生转移,有肺门、纵隔淋巴结以增大、“分叶”征、血管“集束”征及淋巴结转移者LMVD值更高;VEGFR-3阳性表达者CT征象与VEGF-C阳性表达者相似,但其血管“集束”征以VEGFR-3阴性表达者较多见,“棘突”征以VEGFR-3阳性表达者多见。结论CT检查可有效显示周围型肺腺癌的影像学征象,其CT征象与血清VEGF-C、VEGFR-3水平表达,淋巴管生成具有一定相关性,可有效预测肺癌转移与侵袭。

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

The dominant annual cycle of sea surface temperature(SST)in the tropical Pacific exhibits an antisymmetric mode,which explains 83.4%total variance,and serves as a background of El Niño-Southern Oscillation(ENSO).However,there is no consensus yet on its anomalous impacts on the phase and amplitude of *** on data during 1982-2022,results show that anomalies of the antisymmetric mode can affect the evolution of ENSO on the interannual scale via Bjerknes feedback,in which the positive(negative)phase of the antisymmetric mode can strengthen El Niño(La Niña)in boreal winter via an earlier(delayed)seasonal cycle transition and larger(smaller)annual *** magnitude of the SST anomalies in the equatorial eastern Pacific can reach more than±0.3◦C,regulated by the changes in the antisymmetric mode based on random sensitivity *** reveal the spatial pattern of the annual cycle associated with the seasonal phase-locking of ENSO evolution and provide new insight into the impact of the annual cycle of background SST on ENSO,which possibly carries important implications for forecasting ENSO.

The underlying physics of QCD phase transition in the early Universe remains largely unknown due to its strong-coupling nature during the quark-gluon plasma/hadron gas transition, yet a holographic model has been proposed to quantitatively fit the lattice QCD data while with its duration of the first-order phase transition(FoPT) left undetermined. At specific baryon chemical potential, the first-order QCD phase transition agrees with the observational constraint of baryon asymmetry. It, therefore, provides a scenario for phase transition gravitational waves(GWs) within the standard model of particle physics. If these background GWs could contribute dominantly to the recently claimed common-spectrum red noise from pulsar timing array(PTA) observations, the duration of this FoPT can be well constrained, and the associated primordial black holes are still allowed by current observations.
