The preparation and coordination chemistry of iPr2P(E)NHP(E′)iPr2 (E, E′=Se; E=Se, E′=S; E=S, E′=O; E,E′=O

Inorganica Chimica Acta, 1999
Reaction of i Pr 2 PCl with (Me 3 Si) 2 NH gives i Pr 2 PNH i PPr 2 (not isolated) which was oxidised with sulfur/selenium/oxygen to give i Pr 2 P(E)NHP(E′) i Pr 2 (E, E′=Se; E=Se, E′=S; E=S, E′=O; E,E′=O). These neutral LH molecules readily undergo deprotonation/complexation to form simple ML 2 species and demonstrative examples with Zn, Cd, Pd,

Positive affect facilitates creative problem solving.

Journal of Personality and Social Psychology, 1987
Four experiments indicated that positive affect, induced by means of seeing a few minutes of a comedy film or by means of receiving a small bag of candy, improved performance on two tasks that are generally regarded as requiring creative ingenuity ...

A gene encoding an antigen recognized by cytolytic T lymphocytes on a human melanoma.

Science, 1991
Many human melanoma tumors express antigens that are recognized in vitro by cytolytic T lymphocytes (CTLs) derived from the tumor-bearing patient. A gene was identified that directed the expression of antigen MZ2-E on a human melanoma cell line.

DEPOLARIZATION IN e+e- AND e-e- COLLISIONS

International Journal of Modern Physics A, 2000
I make some comments on the depolarization in beam–beam interactions at electron–electron and electron–positron colliders and present some results from a CAIN study of this effect.

Scaling Theory of Localization: Absence of Quantum Diffusion in Two Dimensions

, 1979
Arguments are presented that the $T=0$ conductance $G$ of a disordered electronic system depends on its length scale $L$ in a universal manner. Asymptotic forms are obtained for the scaling function $\ensuremath{\beta}(G)=\frac{d\mathrm{ln}G}{d\mathrm{ln}
