Surface smoothness is one of the properties determining the performance of stents. Therefore, surface polishing shows its importance in the exploitation and production of stents. The present study explores electrochemical polishing of 316L stainless steel slotted tube coronary stents produced by laser cutting. Acid pickling was also studied as a pre-treatment of electrochemical polishing of the...

In this paper, a new approach for estimating the number of wideband sources is proposed which is based on RSS or ISM algorithms. Numerical results show that the MDL-based and EIT-based proposed algorithm havea much better detection performance than that in EGM and AIC cases for small differences between the incident angles of sources. In addition, for similar conditions, RSS algorithm offers hi...

Extensive research on the nutritional and medical application of selenium nanoparticles (SeNPs) was performed in past decades. Besides nutritional values, new characteristics such as antibacterial and anticancer properties depict a bright future for high Selenium (Se) consumption in the coming years. Se is essential for the proper functioning of most of the m...

Endothelial cells play remarkable roles in regulating vascular function in health and disease. Meanwhile, shear stress, which is created due to the friction of the flowing blood on the endothelium of the arterial wall, is critical for vascular homeostasis. Here, the shear stress patterns and its effect on gene expression and vascular function are reviewed.

Recently, entanglement-assisted quantum error correcting codes (EAQECCs) have been constructed by cyclic codes and negacyclic codes. In this paper, by analyzing the cyclotomic cosets in the defining set of constacyclic codes, we constructed three classes of new EAQECCs which satisfy the entanglement-assisted quantum Singleton bound. Besides, three classes of EAQECCs with maximal entanglement fr...

-More embedded microprocessors are emerging and more multithreaded tasks need to be executed simultaneously on embedded device. This paper proposes a multithreaded architecture for embedded processor. It improves the system performance in a large degree meanwhile considering reducing energy dissipation and improving the cache utilization in limited size. Key-Words: multithreading technology, th...

An offi cial committee now ponders the question of whether human impacts have derailed the Earth system suffi ciently to declare the beginning of a new geological epoch, the Anthropocene. Meanwhile, researchers have updated and improved two infl uential assessments of our global status, namely the ‘planetary boundaries’ and the ‘great acceleration’ graphs. Michael Gross reports. Assessing human...

Radiation-induced gliomas are uncommon and therapeutic options are limited due to prior exposure to radiotherapy. Meanwhile, the chemotherapeutic response of anaplastic ependymoma, another rare entity in adults, is often disappointing. We report on the first recorded case of radiation-induced anaplastic ependymoma, in which an excellent clinical response to temozolomide was demonstrated.

This demo showcase the Community Extraction Cloud (CEC) system. The key idea is to drop weak-tie nodes by efficiently extracting core nodes based on the novel concept of asymptotically equivalent structures (AES) and parallel AES mining algorithm. Meanwhile, to facilitate storing and processing of massive networks, several cloud computing technologies including HDFS, Katta, and Hama are seamles...

Introduction A patient with familial Mediterranean fever (FMF) in addition to undiagnosed Anklosing Spondylitis (AS) and also having cutaneous leukocytoclastic vasculitis (LV) is presented. Coexistence of FMF with inflammatory disorders including spondyloarthritis and various systemic vasculitides has been reported before. Meanwhile this is the first reported case of FMF, AS, and LV present tog...
