In euvolemic hyponatremia, endocrinopathies such as hypothyroidism and adrenal insufficiency are possible etiologies. Secondary (SAI) can cause hyponatremia due to impaired free water excretion. Panhypopituitarism is a etiology of gradual onset where gonadotropins (FSH, LH) lose production followed by TSH ACTH. We present case an ACTH stimulation test misled the diagnostic workup. A 69-year-old...

This article aims to investigate the character of transatlantic security relations in Africa: How can it be characterized? Have they become weaker or stronger over past decade? this development explained? As NATO has not yet been heavily engaged on African continent, is prudent study between EU and US. Africa concern (and its member states) for decades due geographical closeness historic bonds....

For encryption schemes, key dependent message (KDM) security requires that ciphertexts preserve secrecy even when the encrypt messages may depend on the secret keys. While KDM security has been extensively studied for public-key encryption (PKE), it receives much less attention in the setting of identity-based encryption (IBE). In this work, we focus on the KDM security for IBE. Our results are...

We submitted a public-key encryption scheme, EPOC, and digital signature scheme, TSH-ESIGN, to IEEE P1363a. The security of EPOC and TSH-ESIGN is based on the intractability of factoring n = pq, where p and q are primes. TSH-ESIGN is also based on the intractability of the approximate e-th root (AERP) assumption, which is the approximate version of the RSA assumption. This draft describes the l...

We outline the linguistic problem of word-sense ambiguity and demonstrate its relevance to current computer security applications in the context of Human Interactive Proofs (HIPs). Such proofs enable a machine to automatically determine whether it is interacting with another machine or a human. HIPs were recently proposed to fight abuse of web services, denial-of-service attacks and spam. We de...

Terror is a modern war strategy which uses violence as a means of communication in order to achieve political objectives. In today’s security environment narrowing the propaganda field of terrorist organization is the primary goal for the security forces. In this sense, providing and maintaining public support is the most necessary ability for security units. Rather than enemy and threat-orient...
