Experiments using the Surface Force Apparatus (SFA) have found anomalously long-ranged charge–charge underscreening in concentrated salt solutions. Meanwhile, theory and simulations have suggested ion clustering to be a possible origin of this behavior. The popular Restricted Primitive Model of electrolyte solutions, in which the solvent is represented by a uniform relative dielectric constant, εr

Protein transport across the cytoplasmic membrane of bacterial cells is mediated by either the general secretion (Sec) system or the twin-arginine translocase (Tat). The Tat machinery exports folded and cofactor-containing proteins from the cytoplasm to the periplasm by using the transmembrane proton motive force as a source of energy. The Tat apparatus apparently senses the folded state of its pr

We present a micro-Raman study of InP/InGaP tandem junction photovoltaic nanowires. These nanowires render possible InGaP compositions that cannot be made in thin films due to strain. The micro-Raman spectra acquired along the nanowires reveal the existence of compositional changes in the InGaP alloy associated with the doping sequence. The heavily Zn-doped InxGa1-xP (x is the In molar fraction) s

Renal hyperparathyroidism (rHPT) is a complex and challenging disorder. It develops early in renal failure, mainly as a consequence of reduced levels of vitamin D, hypocalcemia, diminished excretion of phosphate, and inability to activate vitamin D. RHPT is associated with increased risk of fractures, cardiovascular disease and death. The diagnosis of rHPT rests on demonstrating elevated levels of

Multiconfigurational pair-density functional theory (MC-PDFT) offers a promising solution to the challenges faced by traditional density functional theory (DFT) in addressing molecular systems containing transition metals, open-shells, or strong correlations in general. By utilizing both the density and on-top pair-density, MC-PDFT can make use of a more flexible multiconfigurational wave function

The Båstad tennis protest of 1968: Left-wing activism and right-wing counter-mobilisationIn the spring of 1968, Sweden was supposed to play a Davis Cup tennis match against Rhodesia, a quasi-apartheid state in southern Africa. The game was scheduled to be played on 3 May in the small town of Båstad in southern Sweden. However, hundreds of anti-racist activists gathered and stopped the game from st

Within the lichen family Teloschistaceae, a high number of genera are restricted to the extreme southern part of the Southern Hemisphere. The taxonomy and phylogeny of the southern genus Gondwania have been analyzed based upon fieldwork in Antarctica, Patagonia, New Zealand and Tasmania and subsequent studies including molecular methods. Five species are accepted in the genus Gondwanea including G

Objective: Serum is usually added to growth media when mammalian cells are cultured in vitro to supply the cells with growth factors, hormones, nutrients and trace elements. Defined proteins and metal ions, such as insulin, growth factors, transferrin and sodium selenite, are sometimes also included and can in some cases substitute serum components. How adaptation to serum free media influences ce

The generalized asymmetric Laplace (GAL) distributions, also known as the variance/mean-gamma models, constitute a popular flexible class of distributions that can account for peakedness, skewness, and heavier-than-normal tails, often observed in financial or other empirical data. We consider extensions of the GAL distribution to the matrix variate case, which arise as covariance mixtures of matri
