We consider the effect of the finite size in the ab plane on the surface density of states (DOS) in clean d-wave superconductors. We demonstrate that the angle-resolved DOS consists of energy bands that are formed similarly to the Kronig-Penney model. In contrast to the gapless DOS on a surface of a bulk sample, finiteness of the superconductor in one dimension provides the energy gap for all d...

In this Letter we discuss various properties of the local density of states (DOS) for a superconductor-ferromagnet hybrid system. The DOS is modified at small energies on both sides of the interface. Due to the interplay of superconductivity and ferromagnetism, the local DOS depends on the spin direction. The spin polarization effects extend over a long distance from the interface both in the s...

We measured the phonon density of states (DOS) of nanocrystalline Fe by resonant inelastic nuclear g-ray scattering. The nanophase material shows large distortions in its phonon DOS. We attribute the high energy distortion to lifetime broadening. A damped harmonic oscillator model for the phonons provides a low quality factor, Qu, averaging about 5, but the longitudinal modes may have been broa...

Denial of Service(DoS) attacks pose a big threat to any electronic society. DoS and DDoS attacks are catastrophic particularly when applied to highly sensitive targets like Critical Information Infrastructure. While research literature has focussed on using various fundamental classifier models for detecting attacks, the common trend observed in literature is to classify DoS attacks into the br...

DoS attacks (Denial of Service) are one of the main problems on computer security field. Usually these attacks result in the loss of network connectivity due to excessive bandwidth-consuming and resource bottlenecks of the system attacked. DoS attacks can occur in various ways; however all of them have in common the use of IP protocol. This work presents the effects on network elements and secu...

Eletrodo de diamante foi usado para avaliar a interação dos nucleotídeos guanosina monofosfato (GMP) e adenosina monofosfato (AMP) com os pesticidas clorpirifós, metamidofós e monocrotofós. Observaram-se alterações nas correntes e potenciais de picos dos voltamogramas dos nucleotídeos na presença dos pesticidas dependendo da concentração de pesticida (de 5,0 × 10 a 5,0 × 10 mol L) e do tempo de...

Article history: Received 15 February 2015 Received in revised form 2 December 2015 Accepted 3 December 2015 Available online 23 March 2016 The modeling of the transient subgap density of states (DOS) for the investigation of trap densities in the oxidebased thin-film transistors is proposed. The study is based on both transient measurements and physical modeling. In history, the subgap DOS mod...
