neuroblastoma is a common tumor in pediatric cancer and which might present with usual or unusual clinical features. one of the rare clinical finding of neuroblastoma is paraneoplastic syndromes. we report a two year-old girl with presentation of bilateral ptosis and abdominal pain which was diagnosed as having neuroblastoma. our case is a very rare case of neuroblastoma accompanied by bilatera...

Security and privacy are very important challenges for outsourced private data over cloud storages. By taking Attribute-Based Encryption (ABE) for Access Control (AC) purpose we use fine-grained AC over cloud storage. In this paper, we extend previous Ciphertext Policy ABE (CP-ABE) schemes especially for mobile and resource-constrained devices in a cloud computing environment in two aspects, a ...

conclusions the current study showed that poorness and unreliability of “al-kafi” narratives is a vain thought. hence, it is recommended to perform clinical trial studies (at least) on accurate/authentic narratives, and also consider them as reputable and valid narratives, along with traditional medicine references. results from all narratives of the book “al-kafi” (pillars, furoo, and rouzat a...

Smart grid concept is introduced to modify the power grid by utilizing new information and communication technology. Smart grid needs live power consumption monitoring to provide required services and for this issue, bi-directional communication is essential. Security and privacy are the most important requirements that should be provided in the communication. Because of the complex design of s...

hip fractures are one of the most common injuries which present to an orthopaedic surgeon. most of these cases are unilateral .bilateral simultaneous femur neck fracture is a rare occurrence. we report a case of a bilateral neck femur fracture in a 30 year male following a generalized tonic clonic seizure in view of its rarity and also to increase the awareness of such rare injuries. the patien...

The security models for Authenticated Key Exchange do not consider leakages on pre–computed ephemeral data before their use in sessions. We investigate the consequences of such leakages and point out damaging consequences. As an illustration, we show the HMQV–C protocol vulnerable to a Bilateral Unknown Key Share (BUKS) and an Unilateral Unknown Key Share (UUKS) Attack, when precomputed ephemer...

Advanced metering infrastructure (AMI) is a key part of the smart grid; thus, one of the most important concerns is to offer a secure mutual authentication.  This study focuses on communication between a smart meter and a server on the utility side. Hence, a mutual authentication mechanism in AMI is presented based on the elliptic curve cryptography (ECC) and one time signature (OTS) consists o...
