The use of proxy signature has attracted considerable attention and has been deployed in many applications. Unfortunately, most of the proxy signature schemes, which have been proposed up to now, are not based on standard signature such as Digital Signature Algorithm (DSA). Consequently, those proposals have inevitably been considered infeasible because of obvious security weaknesses so they su...
AIM An image fusion of 3-dimensional (D) digital subtraction angiography (DSA) and magnetic resonance (MR) images, DSA-MR fusion, can simultaneously visualize both information of the vasculature provided by 3D DSA and of the soft tissues provided by MR images. The authors assessed the usefulness of DSA-MR fusion images concerning the pretreatment evaluation for cerebral arteriovenous malformati...
BACKGROUND At our institution, until April 2013, patients who showed early donor specific anti-HLA antibodies (DSA) after lung transplantation were preemptively treated with therapeutic plasma exchange (tPE) and a single dose of Rituximab. In April 2013, we moved to a therapy based on IgM-enriched human immunoglobulins (IVIG), repeated every 4 weeks, and a single dose of Rituximab. METHODS Th...
BACKGROUND Apheresis-based desensitization allows for successful transplantation across major immunological barriers. For donor-specific antibody (DSA)- and/or crossmatch-positive transplantation, however, it has been shown that even intense immunomodulation may not completely prevent antibody-mediated rejection (ABMR). METHODS In this study, we evaluated transplant outcomes in 101 DSA+ decea...
In recent years, directed self-assembly (DSA) has demonstrated tremendous potential to reduce cost for multiple patterning with fewer masks, especially for via patterning. DSA is considered as one of the next generation lithography candidates or complementary lithography techniques to extend 193i lithography further for the sub7 nm nodes. In this work, we focus on the simultaneous DSA guiding t...
Dynamic Spectrum Allocation (DSA) has been viewed as a promising approach to improving spectrum efficiency. With DSA, Wireless Service Providers (WSPs) that operate in fixed spectrum bands allocated through static allocation can solve their short-term spectrum shortage problems resulting from the bursty nature of wireless traffic. Such DSA mechanisms should be coupled with dynamic pricing schem...
Conventional digital subtraction angiography (DSA) identified a right carotid-cavernous fistula (CCF). Three-dimensional DSA (3D-DSA) was used to evaluate the CCF before treatment. The 3D-DSA images showed the anatomical relationship of the parent artery and the veins, which was difficult to understand on conventional DSA. The endoscopic image revealed the fistula and cavernous sinus. The direc...
Ubiquitous wireless networking calls for efficient dynamic spectrum allocation (DSA) among heterogeneous users with diverse transmission types and bandwidth demands. To meet user-specific quality-of-service (QoS) requirements, the power and spectrum allocated to each user should lie inside a bounded region in order to be meaningful for the intended application. Most existing DSA methods aim at ...
Hyperacute kidney rejection is unusual in crossmatch positive recipients of simultaneous liver-kidney transplants (SLKT). However, recent data suggest that these patients remain at risk for antibody-mediated kidney rejection. To further investigate the risk associated with donor-specific alloantibodies (DSA) in SLKT, we studied 86 consecutive SLKT patients with an available pre-SLKT serum sampl...
PURPOSE Preformed circulating donor-specific antibodies (DSAs) immunologically challenge vascular endothelium and the bile duct. However, the liver is an immune-tolerant organ and can avoid immunological challenges. This study was undertaken to analyze the effects of DSAs after adult living donor liver transplantation (LDLT). METHODS We retrospectively reviewed 219 LDLT patients' records trea...
