BACKGROUND Hip fractures are associated with increased mortality and are a known adverse effect of androgen deprivation therapy (ADT) for prostate cancer (PCa). It was our aim to evaluate how mortality after hip fracture is modified by PCa and ADT. METHODS PCa dataBase Sweden (PCBaSe 2.0) is based on the National PCa Register and also contains age and county-matched PCa-free men. We selected ...

چکیده: اجرای احکام کیفری از دیرباز و همواره به دلیل ارتباط تنگاتنگ آن با ( محکوم، بزه دیده و جامعه ) از اهمیت خاصی برخوردار بوده. از همین رو، با توجه به معضلات و مشکلات به وجود آمده در این زمینه، قانون گذار کیفری بر آن شد تا با عنایت به پیشرفت های حاصله در زمینه اجرای احکام جزایی در کشور های مترقی و پیشگام و با نگرشی ویژه به مقام دادرس اجرای کیفر در کشور فرانسه، سرانجام در قوانین جزایی اخیرالت...

Since it is not possible to compute E-scores for 10-mers from PBM data, we used 10-mer pseudo-intensities to perform an analysis similar to the one described in the main text for 8-mer E-scores. We estimated the 10-mers intensities from the 7-mer and 8-mer median intensities. Let X = X1X2 . . . Xk be a DNA site of length k, with Ik(X) it’s median intensity, and Ek(X) it’s energy. Then the inten...

1 Intro The theme of these two lectures is that for L2 methods we need not work in infinite dimensional spaces. In particular, we can unadaptively find and work in a low dimensional space and achieve about as good results. These results question the need for explicitly working in infinite (or high) dimensional spaces for L2 methods. In contrast, for sparsity based methods (including L1 regulari...

In this project we investigate two machine learning methods, one supervised and one unsupervised, that will allow the information content of Yelp data to be efficiently conveyed to the users. The first is matrix completion via the novel ”max-norm” constraint which out results show to be more powerful than the traditional nuclear norm minimization. The second is text summary via sparse PCA which...

Principal component analysis or PCA has been traditionally used as one of the feature extraction techniques in face recognition systems yielding high accuracy when requiring a small number of features. However, the covariance matrix and eigenvalue decomposition stages cause high computational complexity, especially for a large database. Thus, this research presents an alternative approach utili...

Principal Component Analysis (PCA) is one of the feature extraction techniques, commonly used in human facial recognition systems. PCA yields high accuracy rates when requiring lower dimensional vectors; however, the computation during covariance matrix and Eigenvalue Decomposition (EVD) stages leads to a high degree of complexity that corresponds to the increase of datasets. Thus, this researc...

The network traffic data used to build an intrusion detection system is frequently enormous and redundant with important useless information which decreases IDS efficiency. In order to overcome this problem, we have to reduce as much as possible this meaningless information from the original high dimensional data. To do this, we have compared the performance of two features reduction techniques...

Glomerular fibrin deposition and augmentation of procoagulant activity (PCA) are dependent on glomerular macrophage infiltration in anti-glomerular basement membrane antibody-induced glomerulonephritis (anti-GBM GN) in rabbits. Expression of PCA on the surface of glomerular macrophages and/or augmentation of intrinsic glomerular cell PCA by macrophage cytokines (such as IL 1) are potential mech...

Arginase 2, inducible- and endothelial-nitric-oxide synthase (iNOS and eNOS), indoleamine 2,3-dioxygenase (IDO) and TGF-beta, might impair immune functions in prostate cancer (PCA) patients. However, their expression was not comparatively analysed in PCA and benign prostatic hyperplasia (BPH). We evaluated the expression of these genes in PCA and BPH tissues. Seventy-six patients (42 BPH, 34 PC...
