Stimulation of tyrosine phosphorylation by platelet-derived growth factor
Nature of relaxation processes revealed by the action signals of intensity-modulated light fields
We present a generalized theory and experimental results of the action signals induced by the absorption of two photons from two phase-modulated laser beams. In our experiment, the phases of the laser beams are modulated at the frequencies φ1 and φ2, respectively. Their collinear combination leads to the modulation of the total intensity at the frequency φ=φ2-φ1. The action signals, such as photol

Interfacial Structures of Trihexyltetradecylphosphonium-bis(mandelato)borate Ionic Liquid Confined between Gold Electrodes
Atomistic molecular dynamics simulations have been performed to study microscopic the interfacial ionic structures, molecular arrangements, and orientational preferences of trihexyltetradecylphosphonium-bis(mandelato)borate ([P6,6,6,14][BMB]) ionic liquid confined between neutral and charged gold electrodes. It was found that both [P6,6,6,14] cations and [BMB] anions are coabsorbed onto neutral el

A thermodynamically consistent finite strain micro-sphere framework for phase-transformations
We extend a thermodynamically consistent finite strain micro-sphere framework elaborated by Carol et al. towards the modelling of phase-transformations to allow for the simulation of polycrystalline solids such as, e.g., shape memory alloys and shape memory polymers undergoing large deformations. The considered phase-transformation mechanism is based on statistical physics and allows the considera
Effects of CRF2R agonist on tumor growth and cachexia in mice implanted with Lewis lung carcinoma cells
Previous studies have demonstrated an effect of corticotropin-releasing factor 2 receptor (CRF2R) agonists in the maintenance of skeletal muscle mass. The aim of this study was to evaluate the effects of a CRF2R agonist in preserving skeletal muscle in a mouse cachexia model. Implantation of a fast-growing tumor to mice (Lewis lung carcinoma) resulted in a clear cachectic state characterized by a
M2-like macrophages induce colon cancer cell invasion via matrix metalloproteinases
The inflammatory milieu plays an important role in colon cancer development and progression. Previously, we have shown that tumor-associated macrophages (TAMs), an important component of the tumor microenvironment, are enriched in tumors compared with normal tissue and confer a poorer prognosis. In the present study, we found that matrix metallopeptidase-9 (MMP-9), which degrades extracellular mat

TRIM28 Controls a Gene Regulatory Network Based on Endogenous Retroviruses in Human Neural Progenitor Cells
Endogenous retroviruses (ERVs), which make up 8% of the human genome, have been proposed to participate in the control of gene regulatory networks. In this study, we find a region- and developmental stage-specific expression pattern of ERVs in the developing human brain, which is linked to a transcriptional network based on ERVs. We demonstrate that almost 10,000, primarily primate-specific, ERVs

The large influence of climate model bias on terrestrial carbon cycle simulations
Global vegetation models and terrestrial carbon cycle models are widely used for projecting the carbon balance of terrestrial ecosystems. Ensembles of such models show a large spread in carbon balance predictions, ranging from a large uptake to a release of carbon by the terrestrial biosphere, constituting a large uncertainty in the associated feedback to atmospheric CO 2 concentrations under glob
High-average power high-harmonic and attosecond sources : Status and prospects
Experiments employing extreme ultraviolet sources based on high harmonic generation often suffer from photon flux limitations. We discuss current status and prospects for scaling such sources to higher repetition rate, pulse energy and average power.
Towards brand ecology : An analytical semiotic framework for interpreting the emergence of place brands
Brand-management philosophy has recently expanded to include public and spatial contexts producing a cacophony of logos, slogans and events all aimed at promoting and marketing places. Yet, there is still a lack of understanding about how the brand-management philosophy changes when moving into and across places and in which way places change when affected by this way of thinking. Through a multi-

Retrofitting Electrically Heated Single-Family Houses to Net-Zero Energy
Only in Sweden, single-family houses account for approximately 30% of energy use in all buildings and a large part uses only electricity for heating. The potential for improvements on energy efficiency in these houses is large. This study theoretically investigates retrofitting of electrically heated Swedish single-family houses by using an air-source heat pump for both space heating and domestic
A partial plesiosaurian braincase from the Upper Cretaceous of Sweden
A partial exoccipital-opisthotic from the uppermost lower Campanian (Upper Cretaceous) of the Åsen locality, Kristianstad Basin, southernmost Sweden, is described and illustrated. The fossil represents the first braincase element of a plesiosaur found in Sweden. It includes the chamber for the ampulla and utriculus, openings for the caudal vertical and horizontal semicircular canals, and four fora
Manipulating charge transfer excited state relaxation and spin crossover in iron coordination complexes with ligand substitution
Developing light-harvesting and photocatalytic molecules made with iron could provide a cost effective, scalable, and environmentally benign path for solar energy conversion. To date these developments have been limited by the sub-picosecond metal-to-ligand charge transfer (MLCT) electronic excited state lifetime of iron based complexes due to spin crossover-the extremely fast intersystem crossing
