Ensuring that the appropriate level of security is available in wireless networks is absolutely essential. To aid in the defense and detection of potential threats, WLANs should employ security solutions that include an anomaly-based intrusion detection system (ADS) that identify wireless network intrusions by gathering and analyzing the data that is available on the system. This paper is to pr...

We use the entropy function formalism to study the effect of the Gauss-Bonnet term on the entropy of spherically symmetric extremal black holes in heterotic string theory in four dimensions. Surprisingly the resulting entropy and the near horizon metric, gauge field strengths and the axion-dilaton field are identical to those obtained by Cardoso et. al. for a supersymmetric version of the theor...

Taking into account the stringent limits from helioseismology observations on possible matter density uctuations described by magnetohydrodynamics theory, we nd the corresponding time variations of solar neutrino survival probability due to the resonant spinavor precession phenomenon with amplitude of order O(10%). We discuss the physics potential of high statistics real time experiments, like ...

In this paper we consider gauge invariant nonminimal couplings of the vector and axial vector components of the torsion tensor to the Standard model fermions and abelian gauge fields. We then determine the constraints on the unknown parameters of the torsion action from its contribution to the muon anomaly. The bounds on the torsion mass and coupling obtained from muon anomaly are finally compa...

In this paper we consider orbifold compactifications of M-theory on S/Z2×T /Z2. We discuss solutions of the local anomaly matching conditions by twisted vector, tensor and hypermultiplets confined on the local orbifold six-planes. In addition we consider phase-transitions among different solutions which are mediated by Mtheory fivebranes which touch the local orbifold planes and are converted t...

A summary is given of the present status of the theory and experiment of the anomalous magnetic moment of the muon. A difference between predicted and measured values is an indication of physics beyond the Standard Model. A new experimental measurement has produced a value which differs from a recent Standard Model prediction by 2.6 standard deviations. The experimental number differs from othe...

We discuss the recently observed excess of high Q2 neutral current deep inelastic scattering events at HERA in the light of supersymmetry with broken R-parity. We find more than one possible solution. We consider the possibilities for testing these hypotheses at HERA, the TEVATRON and at LEP. One lepton-number violating operator can account for both the HERA data and the four-jet anomaly seen b...

We analyze the status of the exotic solutions to the solar neutrino problem, i.e., those solutions based on new phenomena which are not the usual neutrino oscillations induced by masses and mixing. These solutions are based on di erent assumptions: a) resonant spinavor precession induced by non-vanishing neutrino magnetic moment, b) the existence of non-standard avor-changing and non-universal ...

We review the subject of Kähler anomalies in gauged supergravity, emphasizing that field equations are inconsistent when the Kähler potential is non-invariant under gauge transformations or when there are elementary Fayet-Iliopoulos couplings. Flux vacua solutions of string theory with gauged U(1) shift symmetries appear to avoid this problem. The major new result is that the Kähler anomaly inv...
