The gap parameter of the standard BCS model is replaced by the order parameter of the modified Ginzburg–Landau theory. Using this new form of the BCS model, the energy, entropy, and heat capacity of ^(93,94,95)Mo nuclei are calculated. The results are compared with the experimental data and standard BCS results. Since the order parameter does not drop to zero at a critical temperature, our results for thermal properties are free of singularities. We have shown that the heat capacity as a function of temperature behaves smoothly and it is highly in agreement with the experimental heat capacity, while heat capacity behaves singularly and discontinuously in the standard BCS model.A smooth peak in the heat capacity is observed which is interpreted as a signature of the transition from the superfluid to the normal phase.

Optical coherence tomography (OCT) is a relatively new imaging technology which can produce high resolution images of three-dimensional structures. OCT has been mainly used for medical applications such as for ophthalmology and dermatology. In this study we demonstrate its capability in providing much more reliable biometry identification of fingerprints than conventional methods. We prove that OCT can serve secure control of genuine fingerprints as it can detect if extra layers are placed above the finger. This can prevent with a high probability, intruders to a secure area trying to foul standard systems based on imaging the finger surface. En-Face OCT method is employed and recommended for its capability of providing not only the axial succession of layers in depth, but the en-face image that allows the traditional pattern identification. Another reason for using such OCT technology is that it is compatible with dynamic focus and therefore can provide enhanced transversal resolution and sensitivity. Two En-Face OCT systems are used to evaluate the need for high resolution and conclusions are drawn in terms of the most potential commercial route to ex- ploitation.

Virus-induced gene silencing （VIGS） offers a powerful approach for functional analysis of individual genes by knocking down their expression. We have adopted this approach to dissect gene functions in cotton resistant to Verticfllium wilt, one of the most devastating diseases worldwide. We showed here that highly efficient VIGS was obtained in a cotton breeding line （CA4002） with partial resistance to Verticillium wilt, and ghMKK2 and gh Ve I are required for its resistance to Verticillium wilt. Arabidopsis AtBAK1/SERK3, a central regulator in plant disease resistance, belongs to a subfamily of somatic embryogenesis receptor kinases （SERKs） with five members, AtSERK1 to AtSERK5. Two BAK1 orthologs and one SERK1 ortholog were identified in the cotton genome. Importantly, ghBAK1 is required for CA4002 resistance to Verticillium wilt. Surprisingly, silencing of ghBAK1 is sufficient to trigger cell death accompanied with production of reactive oxygen species in cotton. This result is distinct from Arabidopsis in which AtBAK1 and AtSERK4 play redundant functions in cell death control. Apparently, cotton has only evolved SERK1 and BAK1 whereas AtSERK4/5 are newly evolved genes in Arabidopsis. Our studies indicate the functional importance of BAK1 in Verticillium wilt resistance and suggest the dynamic evolution of SERK family members in different plant species.

【目的】通过研究来自极端嗜热厌氧菌Caldicellulosiruptor sp.F32中3个可降解β-1,3-1,4葡聚糖(β-葡聚糖)的糖苷水解酶,解析其在降解β-葡聚糖过程中协同作用,以及异源表达的糖基化修饰对β-葡聚糖酶F32EG5热稳定性的影响,为该系列水解酶的应用提供考据。【方法】通过大肠杆菌异源表达β-葡聚糖酶F32EG5和Lam16A-gh,以及β-葡萄糖苷酶BlgA,利用DNS、TLC等方法检测其在β-葡聚糖降解过程中的协同性及底物耐受能力。随后,利用毕赤酵母对F32EG5进行异源表达,以及对糖基化修饰的p-F32EG5进行酶学对比。【结果】β-葡聚糖酶F32EG5和Lam16A-gh单独作用于底物时,水解产物不同。但混合使用时,低聚合度寡糖的比例增加。β-葡萄糖苷酶BlgA分别与F32EG5和Lam16A-gh复配时,均展示出良好的协同效应和底物耐受能力。此外,利用毕赤酵母异源表达的p-F32EG5,没有明显改变其最适pH和最适温度,但在超高温下(80–90°C)的热稳定性和催化效率相对于未被糖基化的F32EG5提高2倍以上。【结论】葡萄糖糖苷水解酶BlgA分别与β-葡聚糖酶F32EG5、Lam16A-gh复配,在水解β-葡聚糖过程中表现出良好的协同性和底物耐受能力,同时毕赤酵母异源表达的糖基化修饰能提高在超高温环境下的热稳定性能,有利于酶制剂生产造粒过程中的酶活保留,从而使F32EG5具备应用化潜力。
