Steady-state and time-resolved fluorescence studies were performed on aqueous solutions of poly(acrylic acid) hydrophobically modified with two very different levels of naphthalene (Np). It is demonstrated that unique information on association phenomena involving hydrophobe-modifed polymers can be obtained from an extended fluorescence study by using data for a less-modified polymer as a referenc

A bolaform surfactant, 1,12-diascorbyl dodecanedioate (BOLA12), with ascorbic acid units as the polar headgroups was synthesized for the first time. Once dispersed in water above 0.5% w/w, BOLA12 forms hollow nanotubes as revealed by cryo-TEM experiments. These nanostructures transform into clear micellar solutions on heating. X-ray diffraction and SAXS experiments were performed both on the pure

We performed high-resolution simulations of two stellar collisions relevant for stars in globular clusters. We considered one head-on collision and one off-axis collision between two 0.6-Msolar main-sequence stars. We show that a resolution of about 100000 particles is sufficient for most studies of the structure and evolution of blue stragglers. We demonstrate conclusively that collision products

A quarter of DA white dwarfs are metal polluted, yet elements heavier than helium sink down through the stellar atmosphere on time-scales of days. Hence, these white dwarfs must be the currently accreting material containing heavy elements. Here we consider whether the scattering of comets or asteroids from an outer planetary system, following stellar mass-loss on the asymptotic giant branch, can

Individuals with autism spectrum disorder (ASD) experience high levels of anxiety symptomatology with an estimated prevalence rate of anxiety disorders as high as 40 %. It is likely that anxiety is prominent in individuals with ASD throughout the life-span and that factors such as age, IQ, and ASD symptoms may influence the rates, symptoms, or anxiety subtypes. The high comorbidity rate of anxiety

This paper addresses the design of self-timed energy minimum circuits, operating in the sub-VT domain. The paper presents a generic implementation template using bundled-data circuitry and current sensing completion detection. To support this, a fully-decoupled latch controller has been developed, which integrates the current sensing circuitry. The paper outlines a corresponding design flow, which

The multihadron production in the reaction e(+)e(-) -> e(+)e(-) + hadrons has been studied for the first time at LEP2 energies with both scattered e(+) and e(-) detected at very low Q(2), measured by the DELPHI VSAT. A reasonable agreement between data and full simulation is demonstrated and the total gamma gamma hadronic cross-section is estimated for the gamma gamma center of mass energy up to 1

This study presents evidence from event-related potentials for the use of both right- and left-edge boundary tones as cues for syntactic structure during online speech processing. A temporal model for the neurophysiological processing of prosodic features is outlined.

‘Transition’ was a concept used to denote that the former communist states in Europe were on the track towards establishment of a market economy in the wake of the collapsed planned economy. Another connotation of the concept was democracy – or democratisation – and a third, which was introduced when it became obvious that institutions were important for the transition to succeed, the Rechtsstaat,

An improved conventional-to-micro/minichannel threshold was proposed as Bo = 4 and BoRe(1)(0.5) = 200, where Bo is the Bond number and Re-1 is the liquid Reynolds number. The region Bo < 4 and BoRe(1)(0.5) < 200 is termed as micro/minichannel because bubbles tend to be confined and elongated in the channel and the conventional two-phase flow theory loses its applicability. Flow-pattern based heat

This essay deals with mythologizing as an inherent part of historiography, and as a way to imbue the past with meaningfulness, with focus on the commemoration of the Holocaust, the Nazi genocide on European Jewry.

This paper shows a novel methodology to reduce the complexity in unrolled CORDIC architectures. The methodology is based on eliminating the CORDIC stages starting from the first stage. As an example, a six stage CORDIC is used but the methodology is applicable on CORDICs with an arbitrary number of stages. The paper shows that the complexity can be reduced by 25%.

Probiotics, especially in combination with non-digestible oligosaccharides, may balance the gut microflora while multistrain preparations may express an improved functionality over single strain cultures. In vitro gastrointestinal models enable to test survival and growth dynamics of mixed strain probiotics in a controlled, replicable manner.

BACKGROUND Tasquinimod (ABR-215050) is an orally active quinoline-3-carboxamide analog that has completed phase II clinical trial in patients with castration resistant prostate cancer, showing promising inhibiting effects on the occurrence of metastasis and delayed disease progression. Its mechanism of action is not fully elucidated, but previous studies show anti-angiogenic effects and strong int

The aqueous self-assembly behavior of the dyes Quinaldine red acetate and Pyronin Y in a wide range of concentrations is reported here for the first time. 1H NMR spectroscopy, polarized-light optical microscopy, and small and wide X-ray scattering were used to get insight into molecular interactions, phase boundaries and aggregate structure. Quinaldine red acetate and Pyronin Y self-organize into
