Evolution of a random network: Evolution of a random network is a dynamical process, usually leading to emergence of giant component accompanied with striking consequences on the network topology.  To quantify this process, there is a need of inspection on how the size of the largest connected cluster within the network, formula_1, varies with formula_2.  Networks change their topology as they evolve, undergoing phase transitions.  Phase transitions are generally known from physics, where it occurs as matter changes state according to its thermal energy level, or when ferromagnetic properties emerge in some materials as they are cooling down.  Such phase transitions take place in matter because it is a network of particles, and as such, rules of network phase transition directly apply to it.  Phase transitions in networks happen as links are added to a network, meaning that having N nodes, in each time increment, a link is placed between a randomly chosen pair of them.  The transformation from a set of disconnected nodes to a fully connected network is called the evolution of a network.

Taeko Kono: Taeko Kōno (河野 多惠子 , Kōno Taeko , February 24, 1926 – January 29, 2015) is one of the most important Japanese women writers of the second half of the twentieth century, someone whose influence on contemporary Japanese women writers is acknowledged to be immeasurable.  Kōno is one of a generation of remarkable women writers who made an appearance in Japan in the 1960s and 1970s and who include Kurahashi Yumiko, Mori Mari, Setouchi Harumi, and Takahashi Takako (Japanese name order).  She also established a reputation for herself as an acerbic essayist, a playwright and a literary critic.  By the end of her life she was a leading presence in Japan's literary establishment, one of the first women writers to serve on the Akutagawa Literary Prize committee.  Oe Kenzaburo, Japan's Nobel Laureate, described her as the most "lucidly intelligent" woman writers writing in Japan, and the US critic and academic Masao Miyoshi identified her as among the most "critically alert and historically intelligent."  US critic and academic Davinder Bhowmik assesses her as “…one of the truly original voices of the twentieth century, beyond questions of gender or even nationality.”  A writer who deals with some quite dark themes, Kōno is known to readers in English through the collection of short stories "Toddler-Hunting and Other Stories" (New Directions, 1996), which draws together her best writing from the 1960s.

Nanaerobe: Nanaerobes are organisms that cannot grow in the presence of micromolar concentrations of oxygen, but can grow with and benefit from the presence of nanomolar concentrations of oxygen (e.g. "Bacteroides fragilis").  Like other anaerobes, these organisms do not require oxygen for growth.  This growth benefit requires the expression of an oxygen respiratory chain that is typically associated with microaerophilic respiration.  Recent studies suggest that respiration in low concentrations of oxygen is an ancient process which predates the emergence of oxygenic photosynthesis.

Pre-Madonna: Pre-Madonna is a collection of demos by American singer Madonna.
