Recently, Baghery et al. [1, 2] presented some attacks on two RFID protocols, namely Yoon and Jung et al. protocols, and proposed the improved version of them. However, in this note, we show that the improved version of the Jung et al. protocol suffers from desynchronization attack and the improved version of the Yoon's protocol suffers from secret disclosure attack. The succe...

The private information retrieval (PIR) primitive has received a significant amount of attention from the scientific community since it was first proposed by Chor et al. with other cryptographic primitives [6, 12] and improved upper bounds [3, 16] have been obtained. In this paper, we continue along this path and give an improved upper bound for information theoretic PIR. Our protocol and proof...

ν = q · P M = E − E is the lepton’s energy loss in the nucleon rest frame (in earlier literature sometimes ν = q · P ). Here, E and E′ are the initial and final lepton energies in the nucleon rest frame. Q = −q2 = 2(EE′−−→k · −→k )−ml −ml′ where ml(ml′) is the initial (final) lepton mass. If EE′ sin(θ/2) ≫ m2l , m2l′ , then ≈ 4EE′ sin(θ/2), where θ is the lepton’s scattering angle with respect ...

This lagrangian is, of course, invariant under SO(N), rotations of φ in the N dimensional internal space. φj(x) → Ojkφk(x), with O an orthogonal matrix, which leaves ∑ φ invariant. Notice that the mass term has the wrong sign. Had that sign been minus, with a + in the potential energy, the potential’s absolute minimum would have been at ~ φ = 0, the classical vacuum would be at ~ φ = 0, and the...

The aim of this article is to review current knowledge related to the synthesis and characterization of sol gel-derived SBA-16 mesoporous silicas, as well as a review of the state of the art in this issue, to take stock of knowledge about current and future applications. The ease of the method of preparation, the orderly structure, size and shape of their pores and control, all these achievable...

As per the present available information, there is a discrepancy regarding the total number of exons present in MUC16 genomic DNA. This discrepancy is due to the absence/presence of some of the genomic sequences (particularly for the repeat regions) in the available genomic databases. The terminal nine exons on both 5' and 3' ends code for the aminoand carboxyterminal domains of MUC16, respecti...
