Advantages of the e-e- option at linear colliders for the study of supersymmetry are highlighted. The fermion number violating process [Formula: see text] provides unique opportunities for studies of slepton masses and flavor mixings. In particular, slepton mass measurements at the 100 MeV level through threshold scans of scalar pair production may be possible. Such measurements are over an order of magnitude better than those possible in e+e- mode, require far less integrated luminosity, and may lead to precise, model-independent measurements of tan β. Implications for studying gauginos and the importance of accurate beam polarimetry are also discussed.

The hemocyanins of molluscs are aggregates of a cylindrical decameric subparticle that assembles into di-, tri-, tetra-, penta-, and larger multi-decameric particles with masses that are multiples of the 4.4 Md decamer. Electron micrographs of these hemocyanins typically show the particles with two profiles: circular representing the cylinder viewed from the end and rectangular representing the side-view of the hollow cylinder.The model proposed by Mellema and Klug from image analysis of a didecameric hemocyanin with the two decamers facing one another with collar (closed) ends outward fits the appearance of side-views of the negatively-stained cylinders. These authors also suggested that there might be caps at the ends. In one of a series of transmission electron microscopic studies of molluscan hemocyanins, Siezen and Van Bruggen supported the Mellema-Klug model, but stated that they had never observed a cap component. With STEM we have tested the end cap hypothesis by direct mass measurements across the end-views of unstained particles.

Since the 1990s, a new type of Holocaust story has been emerging in Israeli children's literature. This new narrative is directed towards very young children, from preschool to the first years of elementary school, and its official goal is to instil in them an authentic ‘first Holocaust memory’. This essay presents the literary characteristics of this new Holocaust narrative for children and its master narrative. It brings into light a new profile of both writers and readers. The writers were young children during the Holocaust, and first chose to tell their stories from the safe distance of three generations. The readers are their grand-children and their grand-children's peers, who are assigned an essential role as listeners. These generational roles – the roles of a First Generation of writers and of a Third Generation of readers – are intrinsically familial ones. As such, they mark a significant change in the profile of yet another important figure in the Israeli intergenerational Holocaust discourse, the agent of the Holocaust story for children. Due to the new literary initiatives, the task of providing young children with a ‘first Holocaust memory’ is transferred from the educational authority, where it used to reside, to the domestic sphere.
