An investigation is performed into the optical, electrical, and microstructural properties of Ti-Ga-doped ZnO films deposited on polyimide (PI) flexible substrates and then annealed at temperatures of 300 °C, 400 °C, and 450 °C, respectively. The X-ray diffraction (XRD) analysis results show that all of the films have a strong (002) Ga doped ZnO (GZO) preferential orientation. As the annealing ...

Treatment of boryllithium (THF)2Li[B(NDippCH)2] (Dipp = 2,6-diisopropylphenyl) with various amounts of AlMe3 or GaMe3 leads to the formation of inter group 13 compounds. Equimolar reactions result in ate complexes of the type (THF)nLi(Me3M)[B(NDippCH)2] (M = Al, Ga) with discrete (n = 2, 3) or eight-membered ring structures (n = 1). We reported previously that use of excessive amounts of group ...

Using only linear algebra over Zp, we de ne a discrete probability distribution on the set of isomorphism classes of short exact sequences of Zp-modules, and then conjecture that as E varies over elliptic curves over a xed global eld k, the distribution of 0→ E(k)⊗Qp/Zp → Selp∞ E →X[p∞]→ 0 is that one. This single conjecture would explain many of the known theorems and conjectures on ranks, Sel...

Large Hall resistance jumps are observed in microdevices patterned from epitaxial (Ga,Mn)As layers when subjected to a swept, in-plane magnetic field. This giant planar Hall effect is 4 orders of magnitude greater than previously observed in metallic ferromagnets. This enables extremely sensitive measurements of the angle-dependent magnetic properties of (Ga,Mn)As. The magnetic anisotropy field...

In preparation for effectiveness trials of candidate vaginal microbicides, scientists are debating trial design and implementation challenges, including choice of control arm(s), product-sharing across arms, and visit schedules. This study involved a survey of South African women participating in an expanded safety trial of the candidate microbicide Carraguard gel. The first 100 consenting wome...

In this paper it is shown that for every prime p > 5 the dimension of the p-torsion in the Tate-Shafarevich group of E/K can be arbitrarily large, where E is an elliptic curve defined over a number field K, with [K : Q] bounded by a constant depending only on p. From this we deduce that the dimension of the p-torsion in the Tate-Shafarevich group of A/Q can be arbitrarily large, where A is an a...

Let E be an elliptic curve over Q and p be a prime of good supersingular reduction for E. Although the Iwasawa theory of E over the cyclotomic Zp-extension of Q is well known to be fundamentally different from the case of good ordinary reduction at p, we are able to combine the method of our earlier paper with the theory of Kobayashi [5] and Pollack [8], to give an explicit upper bound for the ...
