The Holy Grail of condensed matter physics is the ability to solve the 78 year old Schrödinger equation for “real-life” systems. The great difficulty is that the motions of the electrons in molecules and crystals are correlated because of the strong repulsion between their negative charges. The solution of the manyelectron Schrödinger equation (the wavefunction) is therefore a complicated funct...

The X-ray constrained wavefunction (XC-WF) method proposed by Jayatilaka [Jayatilaka & Grimwood (2001) ▸, Acta Cryst. A57, 76-86] has attracted much attention because it represents a possible third way of theoretically studying the electronic structure of atoms and molecules, combining features of the more popular wavefunction- and DFT-based approaches. In its original formulation, the XC-WF te...

Some shallow water benthic foraminifera are able to retain functional chloroplasts (kleptoplasts) from their food source, i.e. diatoms. Here we assessed the functionality of the kleptoplast xanthophyll cycle (XC, i.e. the main diatom short-term photo-regulation mechanism) and we surveyed Haynesina germanica kleptoplast pigment composition over time and at different light regimes. Six common dia...

Malignant gliomas have been shown to release glutamate, which kills surrounding brain cells, creating room for tumor expansion. This glutamate release occurs primarily via system xC , a Na-independent cystine-glutamate exchanger. We show here, in addition, that the released glutamate acts as an essential autocrine/paracrine signal that promotes cell invasion. Specifically, chemotactic invasion ...

The role of partially fluorinated carbon (CFx) supported platinum nanoparticles as proton exchange membrane fuel cell (PEMFC) electrodes in a hydrogen is investigated. CFx employed catalyst support via impregnation for oxygen reduction reaction (ORR) at various loadings to determine the optimal loading ORR and compared widely used (non-fluorinated) Vulcan Carbon (XC-72R). In half-cell testing, ...

We study fragments of a μ-calculus over data words whose primary modalities are ‘go to next position’ (Xg), ‘go to previous position’ (Yg), ‘go to next position with the same data value’ (Xc), ‘go to previous position with the same data value (Yc)’. Our focus is on two fragments that are called the bounded mode alternation fragment (BMA) and the bounded reversal fragment (BR). BMA is the fragme...

Multichain amide-bonded anionic amphiphilic oligomers consisting of dodecyl acrylamide and sodium acrylate (i.e., xC₁₂AAm-yAA, where x and y represent the number of dodecyl acrylamide (C₁₂AAm) and sodium acrylate (AA) units, respectively) were synthesized via the radical oligomerization of two monomers in the presence of 2-aminoethanethiol hydrochloride. Equilibrium and dynamic surface tension,...

INTRODUCTION Despite expanding use of bio-impedance (BI), little is known about its pathophysiologic significance and biological correlates OBJECTIVE: Determine correlations of BI parameters with anthropometry and biomarkers of electrolyte homeostasis, inflammation and liver function in children with severe acute malnutrition (SAM). METHODS We studied Ethiopian children with SAM (mid-arm circ...
