Level functions of quadratic differentials, signed measures, and the Strebel property [PDF]

arXiv, 2016
In this paper, motivated by the classical notion of a Strebel qua- dratic differential on a compact Riemann surface without boundary, we in- troduce several classes of quadratic differentials (called non-chaotic, gradient, and positive gradient) which possess some properties of Strebel differentials and appear in applications.

Alloying induced degradation of the absorption edge of InAs_{x}Sb_{1-x} [PDF]

arXiv, 2007
InAs_{x}Sb_{1-x} alloys show a strong bowing in the energy gap, the energy gap of the alloy can be less than the gap of the two parent compounds. We demonstrate that a consequence of this alloying is a systematic degradation in the sharpness of the absorption edge.

Exploring the brittle-to-ductile transition and microstructural responses of γ−TiAl alloy with a crystal plasticity model incorporating dislocation and twinning

Materials & Design
γ−TiAl alloy, with its high specific strength and creep resistance, is ideal for aerospace engines and gas turbines, but its brittleness poses significant manufacturing and processing challenges.

Composition dependence of magnetoresistance in Fe$_{1-x}$Ni$_{x}$ alloys [PDF]

arXiv, 2019
Resistance of Fe$_{1-x}$Ni$_x$(x=0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 and 0.9) has been measured using four probe method from 5K to 300K with and without a longitudinal magnetic field of 8T. The zero field resistivity of x=0.1 and 0.9 alloys, predominant contribution to resistivity above near room temperature is due to electron-phonon scattering, whereas ...
