This paper presents a non-watermarking algorithm based on the most significant bits to construct the key. Firstly, the binary watermarking image is scrambled and extended to the size of the main image. Then the value of every pixel of the watermarking image is compared with that of the corresponding MSB of the main image. When the compared value is true, the location of the main image is marked by a zero matrix, and the marked zero matrix is a key that can be used to detect the watermarking image later.

本文提出一种基于最高有效位构造密钥的零水印算法，先将二值水印图像置乱并拓展为载体图像的大小，再将其像素值与载体像素的MSB进行对应比较，当比较结果为真时，用一个零矩阵来标记载体像素的位置，被标记过的零矩阵作为密钥来检测水印。

Methods 1038 eyes of 606 consecutive myopic patiences who had bilateral Custom Vue LASIK between March 2006 and August 2006 were involved in the study. Wavefront measurement and iris registration were performed in the upright position with Wavescan aberrometer, then more over iris registrations were performed in the supine positon during the operation with VISX Star S4 IR.

The Trojans led by him and by Iamenus, Orestes, Adamas the son of Asius, Thoon and Oenomaus, raised a loud cry of battle and made straight for the wall, holding their shields of dry ox-hide above their heads; for a while the two defenders remained inside and cheered the Achaeans on to stand firm in the defence of their ships; when, however, they saw that the Trojans were attacking the wall, while the Danaans were crying out for help and being routed, they rushed outside and fought in front of the gates like two wild boars upon the mountains that abide the attack of men and dogs, and charging on either side break down the wood all round them tearing it up by the roots, and one can hear the clattering of their tusks, till some one hits them and makes an end of them- even so did the gleaming bronze rattle about their breasts, as the weapons fell upon them; for they fought with great fury, trusting to their own prowess and to those who were on the wall above them.

就像这样，二位凭待自己的勇力和强健的臂膀，站候着高大的、正向他们迎面扑来的阿西俄斯，毫不退让。特洛伊人直冲而上，对着修筑坚固的护墙，高举着生牛皮做就的战盾，裂开嗓门呼喊，围拥在首领阿西俄斯身边，围拥在亚墨诺斯、俄瑞斯忒斯和阿西俄斯之子阿达马斯，以及俄伊诺毛斯和索昂的身旁。其时，墙内的拉丕赛人正极力催促胫甲坚固的阿开亚人保卫海船，但是，当他们看到特洛伊人正冲向护墙，而达奈人则惊叫着溃跑时，二位冲将出去，拼杀在门前，像两头野猪，在山上站等一群步步进逼的对手，骚嚷的狗和猎人，横冲直撞，连根掀倒一棵棵大树，撕甩出一块块碎片，使劲磨咬着牙齿，发出吱吱嘎嘎的声响，直到被人投枪击中，夺走它们的生命――就像这样，挡护他们胸肩的捏亮的铜甲承受着枪械的重击，发出铿锵的震响。

objective to evaluate the role of mr perfusion weighted imaging in preoperation diagnosis of meningiomas.methods mr perfusion weighted images was performed in 47 patients with meningiomas followed by conventional imaging.results the mean rcbv values of angioblastic was the highest in the parenchyma of tumor.the mean rcbv values of malignant group was the lowest.the biggest mean rcbv values among different type meningiomas was statistically significant.the biggest mean rcbv values between benign and malignant group meningiomas was statistically significant,but not in the peri-tumor edema.conclusion the rcbv values were useful in the preoperative differentiation diagnosis of different types of meningiomas.those in the peri-tumor edema were useless in the preoperative differentiation diagnosis of different types of meningiomas.

目的 探讨磁共振灌注成像技术对脑膜瘤术前分型及良恶性鉴别的临床应用价值。方法对47例脑膜瘤病人行mr灌注成像检查，对5种亚型的良性脑膜瘤的mr灌注成像进行分析，并与非典型性及恶性脑膜瘤进行比较。结果血管瘤型脑膜瘤实质部分的rcbv值均数最高，恶性组脑膜瘤的rcbv值均数最低。各亚型间瘤体实质最大rcbv值均数间差异有统计学意义(p＜0.05)，良恶性脑膜瘤实质部分最大rcbv值均数间差异有统计学意义(p＜0.05)。瘤周水肿区的rcbv值均数间差异无统计学意义(p＞0.05)。结论 rcbv值对脑膜瘤术前分型及良恶性鉴别有所帮助，而瘤周水肿区的rcbv值对脑膜瘤分型及良恶性鉴别未显示临床实用价值。

They suffer from some quantisation noise at smaller pixel sizes but this is fixed by pixel binning to create virtual larger pixels when you need the really high ISOs.

他们遭受一些量化的噪音较小的像素大小，但是这是固定的像素binning创建虚拟较大像素当您需要真正的团结。

Materials and Methods: Six patients with left frontal lobe tumors (4 gliomas, 1 germinoma, 1 intra-axial cavernoma) close to Brocca and Wernicke language areas were studied. BOLD and DTI were performed on a 3.0T magnet GE Signa Excite~(? HD_X, BOLD using the word association paradigm developed in Part I and DTT technique developed in PartII. Language activation maps and fiber tracts were superimposed upon high resolution T1 weighted anatomic images of the brain for displaying the relationship between tumor, language functional areas and white matter tracts.
