This specification defines a new EAP method, EAP-AKA’, a small revision of the EAP-AKA method. The change is a new key derivation function that binds the name of the access network to the keys derived within the method. The new key derivation mechanism has been defined in 3GPP. This specification allows its use in EAP in an interoperable manner. In addition, EAP-AKA’ employs a new hash function...

BACKGROUND AND PURPOSE Our purpose was to evaluate the visualization of the artery of Adamkiewicz (AKA) and the anterior spinal artery (ASA) by using multi-detector row CT. Preoperative detection of the AKA and ASA is important for prevention of ischemic complications of thoracoabdominal aortic surgery. METHODS Data from contrast-enhanced CT of the abdomen of 19 consecutive patients with know...

Key agreement (KA) allows two or more users to negotiate a secret session key among them over an open network. Authenticated key agreement (AKA) is a KA protocol enhanced to prevent active attacks. AKA can be achieved using a public key infrastructure (PKI) or identity-based cryptography. However, the former suffers from a heavy certificate management burden while the latter is subject to the s...

OBJECTIVES To assess the clinical value of several serological markers in Lithuanian patients with rheumatoid arthritis (RA) compared with control patients with rheumatic disease and age matched healthy controls. METHODS Serum samples from 96 patients with RA of approximately 8 years' duration, 90 rheumatic disease controls, and 37 healthy subjects were tested. Antikeratin antibody (AKA), ant...

Alcoholic Ketoacidosis (AKA) is an acute metabolic acidosis that typically occurs in people who chronically abuse alcohol and have a recent history of binge drinking, little or no food intake and persistent vomiting [1]. AKA is a result of starvation with glycogen depletion and counter-regulatory hormone production, an increased ratio of Nicotinamide Adenine Dinucleotide (NADH) to Nicotinamide ...

Few systematic studies exist on the sexual behavior of hunter-gatherers and rural central Africans. This study examines the reasons for having sex, the frequency of sex (coitus) per night, sexual practices during the post-partum sex taboo, and beliefs and practices regarding homosexuality, masturbation, the use of sexual stimulants and a variety of other sexual behaviors. Thirty-fi ve Aka and t...

The so-called antikeratin antibodies (AKA) and the antiperinuclear factor (APF) are the most specific serological markers of RA. Using indirect immunofluorescence, AKA label the stratum corneum of various cornified epithelia and APF the keratohyalin granules of human buccal mucosa epithelium. We recently demonstrated that AKA recognize human epidermal filaggrin. Here, we report the identificati...
