A common approach to the modeling of very thin adhesive films is their replacement \nwith an equivalent contact law, prescribing the jumps in the displacement and \ntraction vector fields at the limit interface as the film thickness goes to zero. From \nthe geometrical point of view, the adhesive film is eliminated, a…

For small organic conjugated molecules the exciton binding energy can be calculated treating molecules as conductor, and is given by a simple relation BE \approx e2/(4πε0εR), where ε is the dielectric constant and R is the equivalent radius of the molecule. However, if the molecule deviates from spherical shape, a min…
We use the t-J model and Mori projection operator formalism for calculating the magnetic susceptibility of p-type cuprates in the superconducting and pseudogap phases. The lack of extended tails in the peaks of the hole spectral function was shown to provide an incommensurate low-frequency response with hole dispersio…

In the continuing search for cheaper, more efficient catalysts for cleansing diesel engine exhaust, researchers report a new class of mixed-phase oxides that under laboratory conditions exceed the performance of expensive commercial platinum-based catalysts (Science, DOI: 10.1126/science.1225091). A team of scientists…
When most graduate students speak about their doctoral research at scientific gatherings, the response is usually polite applause and some probing questions from faculty. But when Christopher E. Wilmer spoke about his graduate work as part of a presentation at the Rice Business Plan Competition in Houston this April,…
The Group III metabotropic glutamate receptors (mGluR) are located presynaptically on axon terminals and act as autoreceptors and heteroreceptors by inhibiting neurotransmitter release. Much has been learned about these receptors through exogenous application of L-serine-O-phosphate (L-SOP), an endogenous amino acid d…

Topological superconductors are gapped superconductors with protected Majorana surface/edge states on the boundary. In this paper, we study the Josephson coupling between time-reversal invariant topological superconductors and s-wave superconductors. The Majorana edge/surface states of time-reversal invariant topologi…

Three dimensional (3D) cell culture is becoming mainstream as it is recognized that many animal cell types require the biophysical and biochemical cues within the extracellular matrix (ECM) to perform truly physiologically realistic functions. However, tools for characterizing cellular mechanical environment are large…

Imaging techniques provide a method for non-invasive longitudinal monitoring of cancer therapies, but common metrics such as tumour size are late markers and do not indicate heterogeneity of response. Apoptotic cell death is an earlier marker of tumour response and produces molecular and cellular-level changes (macrom…
Strict criteria determine the siting of a high-level radioactive waste (HLW) geological repository, but after 20 years of survey and investigation, China has selected a potential candidate area. Bolstered by a US$16bn (£10bn) investment commitment, opportunities exist for commercial and technological cooperation.
Silk fibroin and hydroxyapatite nanocomposites (SF/HA) with various SF content were prepared. Effect of Silk fibroin content on the bionic mineralization and cellular compatibility in vitro of HA nanocrystals (n-HA) was investigated. The results show that SF content has an obvious effect on the nucleation and growth o…
This Paper proposes the high-power non-linear loads and high-power adjustable-speed motor drives, such as mainly used in electric novel ships, the shunt active power filter is proposed here to reduce the harmonic contents in source voltage and source currents of harmonic polluted three phase system supplying a Non-lin…
