Hoop-shaped ?-conjugated macrocycles constitute a new family of systems displaying unique properties induced by their radially directed ?-orbitals.
In this paper, the dynamics of an interface under the influence of surface tension is studied numerically for flow in the Hele-Shaw cell, where the interface separates an expanding bubble of inviscid fluid from a displaced viscous fluid. Of special interest is the long-time behavior of the so-called q-pole initial data, whose motion is explicitly known and globally smooth for the zero surface t...
We give general sufficient conditions for the existence of trapped surfaces due to concentration of matter in spherically symmetric initial data sets satisfying the dominant energy condition. These results are novel in that they apply and are meaningful for arbitrary spacelike slices, that is, they do not require any auxiliary assumptions such as maximality, time symmetry, or special extrinsic ...
Saeki, Yasutake, Satoshi Kurihara, Kimiaki Komukai, Tetsuya Ishikawa, and Kiyohiro Takigiku. Dynamic relations among length, tension, and intracellular Ca21 in activated ferret papillary muscles. Am. J. Physiol. 275 (Heart Circ. Physiol. 44): H1957–H1962, 1998.—To study the effects of mechanical constraints on the Ca21 affinity of cardiac troponin C, we analyzed the tension and aequorin light (...
Three related efforts underway at Caltech are discussed: experimental studies of spheromak formation, experimental simulation of solar prominences, and Alfvén wave instability of current sheets. Spheromak formation has been studied by using a coaxial magnetized plasma gun to inject helicity-bearing plasma into a very large vacuum chamber. The spheromak is formed without a flux conserver and int...
The difference in delamination onset predictions based on the type and location of the assumed initial damage are compared in a specimen consisting of a tapered flange laminate bonded to a skin laminate. From previous experimental work, the damage was identified to consist of a matrix crack in the top skin layer followed by a delamination between the top and second skin layer (+45o/-45o interfa...
We report an in situ transmission electron microscopy study of the electrochemical behavior of few-layer graphene nanoribbons (GNRs) synthesized by longitudinal splitting the multi-walled carbon nanotubes (MWCNTs). Upon lithiation, the GNRs were covered by a nanocrystalline lithium oxide layer attached to the surfaces and edges of the GNRs, most of which were removed upon delithiation, indicati...
