To modify the shape difference between the spherical vacancy and the realistic vacancy, a shape factor is introduced into brooks' vacancy model. It is shown that the modified model is more efficient in predicting the vacancy volume of metals than the original one, and the calculated vacancy volumes of 17 metals by the modified model agree with the values reported in literatures. Furthermore, the present results show that the vacancy shape may contribute 2%-9% to the whole vacancy volume.

Mulliken, NPA, MK and CHelpG population analyses have been accomplished at the level of MP2/6-31G（d,p） for the title system. The variations of four kinds of charges on NH3 with intermolecular distance infer that electron transfers from NH3 to H2O. MK and CHelpG population analyses indicate more electron transfer than Mulliken and NPA ones. The atomic charges resulted from MK and CHelpG schemes infer that electron transfers from N in NH3 to H in H2O, which confirms that this bimolecular complex possesses linear structure as H3N…HOH.

The ultra-high-energy（UHE） gamma-ray source 1LHAASO J0007+7303u is positionally associated with the composite SNR CTA1 that is located at high Galactic Latitude b ≈ 10.5°. This provides a rare opportunity to spatially resolve the component of the pulsar wind nebula（PWN） and supernova remnant（SNR） at UHE. This paper conducted a dedicated data analysis of 1LHAASO J0007+7303u using the data collected from December 2019 to July 2023. This source is well detected with significances of 21σ and 17σ at 8-100 TeV and >100 TeV, respectively. The corresponding extensions are determined to be 0.23°±0.03°and 0.17°±0.03°. The emission is proposed to originate from the relativistic electrons accelerated within the PWN of PSR J0007+7303. The energy spectrum is well described by a power-law with an exponential cutoff function dN/dE =（42.4 ± 4.1）(E/（20 TeV）)-2.31±0.11exp(-E/（110±25 TeV）) TeV-1cm-2s-1in the energy range from 8 to 300 TeV, implying a steady-state parent electron spectrum dNe/dEe∝(Ee/（100 TeV）)-3.13±0.16exp[(-Ee/（373±70 TeV）)2] at energies above ≈ 50 TeV. The cutoff energy of the electron spectrum is roughly equal to the expected current maximum energy of particles accelerated at the PWN terminal shock. Combining the X-ray and gamma-ray emission, the current space-averaged magnetic field can be limited to≈ 4.5 μG. To satisfy the multi-wavelength spectrum and the γ-ray extensions, the transport of relativistic particles within the PWN is likely dominated by the advection process under the free-expansion phase assumption.

以g-C_(3)N_(5)、bi(NO_(3))_(3)•5H_(2)O和草酸钠(Na_(2)C_(2)O_(4))为原料,通过水热和煅烧方法制备了g-C_(3)N_(5)/β-bi_(2)O_(3)(CN/bO)复合材料,利用XRD、SEM、TEM、UV-Vis DRS、PL和EIS对CN/bO进行了表征。在模拟自然光条件下,测试了CN/bO对水中盐酸四环素(TC)的光催化降解性能,考察了影响TC降解率的因素及CN/bO的底物普适性和循环使用性能,并对CN/bO光催化降解TC的机理进行了推测。结果表明,CN/bO光催化活性优于单一材料。50CN/bO(即g-C_(3)N_(5)质量为复合材料质量的50%)具有最佳光催化活性,在30 mL TC初始质量浓度为20 mg/L、50CN/bO加入量为20 mg、模拟光光照时间90 min时,TC降解率为94.1%,总有机碳(TOC)去除率为72.5%;光照60 min,其对罗丹明b、孔雀石绿等6种常见水污染物的降解率在81.0%~99.8%之间;溶液中CO_(3)^(2−)可降低TC的降解率,而S_(2)O_(8)^(2−)则可提高TC的降解率;pH=6~12时,50CN/bO光催化性能基本不变;50CN/bO重复使用5次仍保持较高的催化活性;超氧自由基和空穴是CN/bO光催化降解TC反应的主要活性物种。β-bi_(2)O_(3)与g-C_(3)N_(5)之间形成的S型异质结提高了电荷分离和转移能力,增加了CN/bO参与光降解反应的活性基团数目。

When CTLs co-cultured with the UM cells, most UM cells could be eliminated. Survival UM cells grew slowly and were considered to be survival variants and examined by a microarray analysis. These differential genes were analyzed further with Venn Diagrams and functions related to immune escape. We additionally examined transcriptional changes of manually selected survival variants of UM cells and of clinical UM samples by quantitative real-time polymerase chain reaction （qRT-PCR）, and analyzed the correlation of these expressions and patients’ ***： Gene expression analyses revealed a marked up-regulation of SLAMF7 and CCL22 and a significant down-regulation of KRT10, FXYD3 and AbCC2. The expression of these genes in the relapsed UM was significantly greater than those in primary UM. UM patients with overexpression of these genes had a shorter survival period as compared with those of their ***： Gene expression, in particular of SLAMF7, CCL22, KRT10, FXYD3 and AbCC2, differed between primary UM cells and survival variants of UM cells.

The class Pezizomycetes is monophyletic within the subdivision Pezizomycotina. The main distinguishing character of thisclass is operculate asci, although in some taxa this character has been lost. The circumscription of the families and genericlevel delimitation in Pezizomycetes is still controversial, although several molecular phylogenetic studies have beenpublished on this group. This paper reviews 21 families of Pezizomycetes including five new families, which are introduced here, viz. Kallistoskyphaceae, Pseudombrophilaceae, Pulvinulaceae, Strobiloscyphaceae and Tarzettaceae. Moreover, this study provides a modified backbone tree based on phylogenetic analysis of five combined loci. Descriptions andillustrations of representative taxa for the families are provided from collections made in China, Thailand and the UK,herbarium material from international herbaria (FH, FLAS, H, HKAS and MA) and the literature. Pezizales separates intosix major clades. Clade 1 of Pezizales includes the families Ascobolaceae and Pezizaceae. Clade 2 is the new familyKallistoskyphaceae. Clade 3 comprises the families Caloscyphaceae, Karstenellaceae and Rhizinaceae. Clade 4 representsthe families Discinaceae, Helvellaceae, Morchellaceae, Tuberaceae and Underwoodia columnaris lineage. Clade 5includes Chorioactidaceae, Sarcoscyphaceae and Sarcosomataceae and Clade 6 comprises Ascodesmidaceae, Glaziellaceae, Otideaceae, Pseudombrophilaceae, Pulvinulaceae, Pyronemataceae, Strobiloscyphaceae and Tarzettaceae. Newsequence data belonging to ITS, LSU, SSU, TEF, RPb2 gene regions from 40 pezizalian species are provided here. Thepaper provides a working document for apothecial Pezizomycetes which can be modified as new data comes to light. It ishoped that by illustrating taxa we provide stimulation and interest in the operculate discomycetes, so that further research iscarried out on this remarkable, but poorly studied group of fungi.
