In recent years, several protocols for password-based authenticated key exchange have been proposed. These protocols aim to be secure even though the sample space of passwords may be small enough to be enumerated by an off-line adversary. In Eurocrypt 2000, Bellare, Pointcheval and Rogaway (BPR) presented a model and security definition for authenticated(More)
(experimental details are presented elsewhere 9,10). Figure 1a shows the energy–momentum (dispersion) curves of the LSCO system with various dopings (0<xአ0.3), measured along the (0,0)–(Ț,Ț) direction in the Brillouin zone in reciprocal space. This diagonal direction is special in these superconductors because the anisotropic superconducting gap 11 , as(More)
— 1 This paper studies the security requirements for remote authentication and communication in smart grid systems. Though smart card based authentication techniques have been a successful solution for addressing key management challenges in several cryptographic authentication systems, they may not be applicable to smart grid systems. For example, in order(More)
China is one of the richest countries in the world for the diversity of its biological resources. However, China has suffered serious losses of biological resources in recent years, due to the burgeoning growth of economic globalization, international trade, and technology exchange. This comment analyzes data from ports of Entry–Exit Inspection and(More)
BACKGROUND The clonal spread of Acinetobacter baumannii is a global problem, and carbapenems, such as imipenem, remain the first-choice agent against A. baumannii. Using synergy to enhance the antibiotic activity of carbapenems could be useful. Here, amlodipine (AML) was tested alone and with imipenem against A. baumannii isolates. METHODS Forty-two(More)
The (π, π) shadow band (SB) in La-based cuprate family (La214) was studied by angle-resolved photoemission spectroscopy (ARPES) over a wide doping range from x = 0.01 to x = 0.25. Unlike the well-studied case of the Bi-based cuprate family, an overall strong, monotonic doping dependence of the SB intensity at the Fermi level (E F) was observed. In contrast(More)
Ten cases of syringomyelia confirmed by magnetic resonance imaging (MRI) were presented. The cavities in the spinal cord were of low signal on T1 weighted image (T1WI) and high signal on T2 weighted image (T2WI). The segments of the spinal cord with involved lesion resembled "bamboo joints" or were of "beaded" shape on sagittal section image and of(More)
