In fact, this is the sign of true faith, for when its cheerfulness enters and mixes in the hearts completely, nobody will be displeased with it. I asked you whether he had ever broken his promise. You replied in the negative. And such are the apostles; they never break their promises.

Indeed, such are the apostles; they are put to trials and the final victory is always theirs. Then I asked you what he ordered you. You replied that he ordered you to worship Allah alone and not to worship others along with Him, to leave all that your fore-fathers used to worship, to offer prayers, to speak the truth, to be chaste, to keep promises, and to return what is entrusted to you. These are really the qualities of a prophet who, I knew would appear, but I did not know that he would be from amongst you.

Methods A retrospective analysis was performed for images of CT,MRI and DSA of 12 patients with intracranial venous angiomas.In all cases,7 cases male,5 cases female,age ranged from 8 years old to 72 years old.All patients underwent the examinations of CT,MRI and/or DSA.Results All 12 patients had single lesion.In these cases,there were 6 cases （50%） located in cerebella,6 cases （50%） located in cerebra including 3 cases （25%） in lobus frontalis and 3 cases （25%） in lobus parietalis.Most patients had slight clinical symptoms and were detected the lesions accidentally when they were examined for other diseases.Compared the imaging features of CT,MRI and DSA,conventional CT scan was negative,but there were characteristic images which was "dendritic" sign in contrast-enhanced CT and MRI,and typical findings of "caput medusae"sign in venous phase of DSA.

结果 颅内静脉血管瘤均为单发；6例（50%）位於幕下小脑实质内，6例（50%）位於幕上额叶（3例25%）、顶叶（3例25%）脑实质内；患者临床症状轻微，多为合并其他病变检查时偶然发现；CT、MRI及DSA的影像比较，CT平扫为阴性，CT增强扫描与MRI平扫呈特征性表现，即树枝征，DSA静脉期可见典型表现蛇头征。

For the image with random field feature, the description language is probability distribution model, and the description length equals the negative base-two logarithm of the probability of the image data; For the region homogeneity properties of active contour, the description language is chosen as a sign gradient map, and the description length is the summation of sign gradient inside the active contour; For the active contour regularity, the description language is smoothness, and the corresponding description length is the length of active contour curve.

随机场图像的描述语言采用概率分布模型，描述长度是围道内外区域中图像数据概率的以2为底对数的负数；活动围道区域一致性的描述语言为有符号的梯度图，描述长度是围道内区域有符号梯度的总和；围道形态的描述语言采用平滑性，描述长度正比于围道的长度。

When only one operand is negative, the sign and value of the result for the modulus operator can follow either the sign of the numerator or of the denominator.

当只有一个操作数为负数时，求模操作结果值的符号可依据分子或分母的符号而定。

All aforementioned cases entierely were proved pathological diagnosis using operation or lung centesis. Results: On the CT manifestation, lobulation sign and spiculation sign mostly appeared in the malignant nodules. The accurate rate of diagnosis was 75.6; sensitivity were 76.3%; specificity were 74.1%; positive predictive value were 86.5%; negative predictive value were 58.8%.

结果：86例SPN的Cr征象中，分叶征和棘突或毛刺征多出现于恶性结节，与病理和随访结果对比，螺旋CT薄层扫描并MPVR重建判断肺小结节良恶性的准确率、灵敏度、特异性、阳性预测值和阴性预测值分别为75.6%、76.3%、74.1%、86.5%、58.8%。

Neutral differential equations with variable sign coefficients are separated into neutral differential equations with positive and negative coefficients by transformation. According to the characteristic of these equations, a real number set with supremum is constructed, and sufficient conditions for oscillation of all solutions to neutral equations with variable sign coefficients are obtained.

通过变换将具有变号系数的中立型微分方程分解为具有正负系数的中立型微分方程；分析具有正负系数中立型微分方程的特征，构造存在上确界的实数集；并对中立型微分方程的解作细致分析，得到了具有变号系数中立型微分方程所有解振动的充分条件。

Using panel data of listed companies, this paper analyzes it with a quantile regression approach, then draws a conclusion: the share structure and the capability of emerging interior resources effect the capital structure changeably with the different quantiles respectively. That is, for those conditions with low asset-liability ratio, the sign is positive, on the contrary, the sign is negative.

为此本文尝试着将分位数回归理论引入到回归模型中，通过对我国上市公司的相关数据进行分位数回归分析后发现，不同资产负债率水平下，企业股权结构、企业产生内部资源的能力对资本结构的影响效果不同：低负债率水平下，两者均与债务水平正相关；而高负债率水平下，又均与债务水平负相关。

However after we partition the sample into deciles based on the degree of conservatism, we find that the higher the degree of conservatism, the more significant the coefficients on the two variables and the sign of the coefficients are positive as we expect. Furthermore, we find the sign of the coefficients is negative when the assets are overstated (that is, accounting is aggressive instead of conservative).

但将所有观察值以会计保守程度分组进行分析时，则发现营业资产变动和现金投资额变动对股票报酬率均有正向影响，而且随著保守程度的增加，其影响程度也随著增加；另外，本研究发现当资产帐面价值高估时，对股票报酬呈负影响。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
