This paper presents a novel method to construct a dynamic single assignment (DSA) form of array-intensive, pointer-free C programs (or in any other procedural language). A program in DSA form does not perform any destructive update of scalars and array elements, i.e., each element is written at most once. As DSA makes the dependencies between variable references explicit, it facilitates complex...

As we reach the limits of current patterning techniques led by 193nm immersion lithography, the focus is on next generation patterning techniques such as Extreme Ultra Violet Lithography (EUVL) and Directed Self Assembly (DSA) to enable 7nm and 5nm technology nodes. Though there have been great strides in materials development for DSA with high χ materials enabling up to 5 nm pitches, DSA still...

We provide an attack to (EC)DSA digital signature built upon Coppersmith’s method. We prove that, if a, k are the private and ephemeral key, respectively, of the (EC)DSA scheme and (k−1mod q)a < 0.262 · q, then we can efficiently find a.

BACKGROUND AND PURPOSE Our objective was to compare the reliability of CT venography with intraarterial digital subtraction angiography (DSA) in imaging cerebral venous anatomy and pathology. METHODS In 25 consecutive patients, 426 venous structures were determined as present, partially present, or absent by three observers evaluating CT multiplanar reformatted (MPR) and maximum intensity pro...

Today, cloud computing has provided a suitable platform to meet the needs of users. One most important challenges facing is Dynamic Resource Allocation (DSA), which in NP-Hard class. goals DSA utilization resources efficiently and maximize productivity. In this paper, an improved Firefly algorithm based on load balancing optimization introduced solve problem called IFA-DSA. addition workloads b...

Postoperative angiography for aneurysm surgery is essential in identifying those aneurysms that have been inadequately clipped, allowing for additional corrective surgery. The current standard of reference for the postoperative evaluation of clipped aneurysms is digital subtraction angiography (DSA). However, DSA is an invasive method requiring arterial puncture and intraarterial catheter manip...

OBJECTIVE This study compared data on the blood flow velocity in the internal carotid artery, which was obtained using the optical flow method (OFM) with digital subtraction angiography (DSA) and the time-of-flight (TOF) technique using magnetic resonance angiography (MRA). MATERIALS AND METHODS Images were obtained from 12 cerebrovascular patients who underwent both brain DSA and MRA imaging...

DSA images suffer from challenges like system X-ray noise and artifacts due to patient movement. In this paper, we present a two-step strategy to improve DSA image quality. First, a hierarchical deformable registration algorithm is used to register the mask frame and the bolus frame before subtraction. Second, the resulted DSA image is further enhanced by background diffusion and nonlinear norm...

PURPOSE to compare gadolinium-enhanced magnetic resonance angiography (Gd-MRA), digital subtraction angiography (DSA) and duplex of the iliac arteries with intra-arterial pressure gradient measurement as the reference method. MATERIALS AND METHODS Gd-MRA, DSA and duplex examinations of the iliac arteries were performed in 30 patients (60 arteries) with lower-limb arterial occlusive disease. I...
