信用关联结构性存款的定价

为了分散信用风险,一些银行发行了收益与某一信用实体的信用事件挂钩的存款.对挂钩公司的破产,采用结构化方法中的首次通过模型,即在存款期限内,若信用实体资不抵债,就认为信用事件发生.在随机利率假定下,用偏微分方程的方法,给出信用关联存款的的定价公式,并讨论其金融意义.     

2017 年金融运行分析与2018 年展望

在金融去杠杆的政策影响下,2017年货币供应量与社会融资规模增速“一降、一升”,人民币存款与人民币贷款“一少、一增”,金融部门与实体经济杠杆率“一降、一稳”,各类利率水平有所抬升。2018年要紧紧围绕服务实体经济、防控金融风险、深化金融改革三项任务,创新和完善金融调控,积极应对发达国家货币政策正常化、国内融资难、融资贵问题抬头以及各类金融风险点进一步暴露等多重挑战。金融调控要做到“四个加强”：加强货币政策和宏观审慎政策的协调配合,维持经济和金融稳定;加强价格型调控,引导利率水平与人民币汇率平稳运行;加强结构性调控,提高金融服务实体经济效率;加强流动性精细化管理,保持银行体系流动性平稳。

美元做市商制度对人民币汇率形成机制的影响

随着中国银行间外汇市场美元做市商制度的推出，人民币汇率形成机制正在逐步完善。我国目前实行这一制度可能存在管理风险增加、市场监管加大等问题，这就需要采取发展外汇市场金融衍生产品、建立做市商的资信评估制度以逐步提高人民币汇率形成机制的市场化程度。     

分数布朗运动下的看跌期权定价

要对金融产品进行透彻的研究和管理,就必须正确的确定金融衍生物的价格问题,其中,期权定价的研究正是金融领域的重要研究部分。通过研究由分数布朗运动驱动的金融市场,考虑标的资产价格服从几何分数布朗运动,在假定无风险利率和红利发放率非随机的情况之下,将服从普通布朗运动的经典B-S期权定价模型推广至服从分数布朗运动,从而得到欧式看跌期权的定价公式。

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the     

An affordable accurate evaluation of the binding conformations predicted by molecular docking studies in bio-system

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of
