his article presents a comprehensive analysis of the thermal effects in advanced high-performance interconnect systems arising due to self-heating under various circuit conditions, including electrostatic discharge (ESD). Technology (Cu, low-k, etc.) and scaling effects on the thermal characteristics of the interconnects, and on their electromigration (EM) reliability, have been analyzed simult...

Infrared, visible, and near-UV reflectivity measurements are used to obtain conductivity as a function of temperature and frequency in YbInCu4, which exhibits an isostructural phase-transition into a mixed-valent phase below Tv.42 K. In addition to a gradual loss of spectral weight with decreasing temperature extending up to 1.5 eV, a sharp resonance appears at 0.25 eV in the mixed-valent phase...

 Polycrystalline samples of Nd1-xCaxBa2-xLaxCu3O7-δ (with 0.0 ≤ x ≤ 0.15) were prepared by the standard solid state method. The transport and superconducting properties have been studied by the resistivity and thermoelectric power measurements as a function of temperature and doping concentration. With increasing doping concentration, the resistivity was increased and thermoelectric power was c...

saltwater intrusion into freshwater in coastal areas has been a serious concern for many countries. providing fresh water in some regions is very crucial. in fact, the areas that  are prone to encountering salt water zones should be checked meticulously. the preferred method for such investigation is a precise 3-d model of distribution of fresh and salt water in order to reach such a model, rel...

On the basis of field studies, mafic-intermediate bodies of Kashmar are subdivided into the old series (often stocks of gabbro, diorite, quartz diorite/monzodiorite) and the new series (quartz monzodiorite swarm dykes). In terms of crosscutting relationships, old series has the age between oldest volcanic units (57 Ma) and Eocene granitoids (40 Ma), but the swarm dykes are attributed to the pos...

This article examines Pornoterrorismo (2011), written by Spanish transfeminist poet and performer Diana J. Torres. In this book, the author mixes autobiographical details with personal reflections that have motivated her work includes a selection of pornoterrorista poetry. Through close reading narrative poetic voice, essay shows how constructs discourse radical negativity based on discursive f...

We studied resistivity, magnetoresistivity, and Hall resistivity for a few percolating granular NiFe-SiO2 films upon thermal annealing. It was found that both the resistivity and the Hall resistivity decrease by two orders of magnitude upon annealing at 520 °C, accompanied by a crossover from an approximately 2lnT dependence of resistivity to a metallic behavior. On the other hand, transmission...
