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

Reduction of Abeta amyloid pathology in APPPS1 transgenic mice in the absence of gut microbiota

Alzheimer's disease is the most common form of dementia in the western world, however there is no cure available for this devastating neurodegenerative disorder. Despite clinical and experimental evidence implicating the intestinal microbiota in a number of brain disorders, its impact on Alzheimer's disease is not known. To this end we sequenced bacterial 16S rRNA from fecal samples of Aβ precurso

Hybrid Nanowire Ion-to-Electron Transducers for Integrated Bioelectronic Circuitry

A key task in the emerging field of bioelectronics is the transduction between ionic/protonic and electronic signals at high fidelity. This is a considerable challenge since the two carrier types exhibit intrinsically different physics and are best supported by very different materials types - electronic signals in inorganic semiconductors and ionic/protonic signals in organic or bio-organic polym

Spin Orientation of Two-Dimensional Electrons Driven by Temperature-Tunable Competition of Spin-Orbit and Exchange-Magnetic Interactions

Finding ways to create and control the spin-dependent properties of two-dimensional electron states (2DESs) is a major challenge for the elaboration of novel spin-based devices. Spin-orbit and exchange-magnetic interactions (SOI and EMI) are two fundamental mechanisms that enable access to the tunability of spin-dependent properties of carriers. The silicon surface of HoRh2Si2 appears to be a uniq

Relating ICT to organizational change in research and practice

The topic of ICT-enabled organizational change has been a focus of attention in information systems (IS) research for decades. Besson and Rowe (J Strateg Inf Syst 21:103-124, 2012 [17]), however, have identified a lack of description and conceptualization of the transformation process in the main stream of IS research. This paper discusses key IS paradigms in some of the content of commonly and av

Disrupted vegetation as a response to Jurassic volcanism in southern Sweden

Central Skåne (Scania) in southern Sweden hosts evidence of extensive Jurassic volcanism in the form of mafic volcanic plugs and associated volcaniclastic deposits that entomb wellpreserved macro-plant and spore-pollen assemblages. Palynological assemblages recovered from the Höör Sandstone are of Hettangian-Pliensbachian age and those from the overlying lahar deposits are dated as Pliensbachian-e

Construals of meaning : The role of attention in robotic language production

In robotics research with language-based interaction, simplifications are made, such that a given event can be described in a unique manner, where there is a direct mapping between event representations and sentences that can describe these events. However, common experience tells us that the same physical event can be described in multiple ways, depending on the perspective of the speaker. The cu

Psychosocial aspects before and up to 2 years after heart or lung transplantation : Experience of patients and their next of kin

BACKGROUND: Psychosocial factors are important for patients undergoing heart (HTx) or lung (LTx) transplantation and for their next of kin (NoK).AIM: To describe health-related quality of life (HRQoL; patients only), anxiety, depression, stress, coping ability, and burden (NoK only) for patients and their NoK before and up to 2 years after HTx or LTx.DESIGN: Adult patients (28 hearts and 26 lungs)

Soil networks become more connected and take up more carbon as nature restoration progresses

Soil organisms have an important role in aboveground community dynamics and ecosystem functioning in terrestrial ecosystems. However, most studies have considered soil biota as a black box or focussed on specific groups, whereas little is known about entire soil networks. Here we show that during the course of nature restoration on abandoned arable land a compositional shift in soil biota, precede

Advances in heat transfer enhancement

This Brief addresses the phenomena of heat transfer enhancement. A companion edition in the SpringerBrief Subseries on Thermal Engineering and Applied Science to three other monographs including “Critical Heat Flux in Flow Boiling in Microchannels,” this volume is idea for professionals, researchers, and graduate students concerned with electronic cooling.

Cerebellar physiology : links between microcircuitry properties and sensorimotor functions

Existing knowledge of the cerebellar microcircuitry structure and physiology allows a rather detailed description of what it in itself can and cannot do. Combined with a known mapping of different cerebellar regions to afferent systems and motor output target structures, there are several constraints that can be used to describe how specific components of the cerebellar microcircuitry may work dur

A neutron-antineutron oscillation experiment at the European Spallation Source

Neutral particle oscillations have proven to be extremely valuable probes of fundamental physics. For instance, kaon oscillations provided us with our first insight into CP-violation, B oscillations form the most fertile ground for the continued study of CP-violation, and neutrino oscillations suggest the existence of a new, important energy scale well below the GUT scale. Neutrons oscillating int

Particle filtering based identification for autonomous nonlinear ODE models

This paper presents a new black-box algorithm for identification of a nonlinear autonomous system in stable periodic motion. The particle filtering based algorithm models the signal as the output of a continuous-time second order ordinary differential equation (ODE). The model is selected based on previous work which proves that a second order ODE is sufficient to model a wide class of nonlinear s

It can't happen, it's a bad idea, it won't last : U.S. economists on the EMU and the euro, 1989-2002

On the whole, the euro has, thus far, gone much better than many U.S. economists had predicted. We survey how U.S. economists viewed European monetary unification from the publication of the Delors Report in 1989 to the introduction of euro notes and coins in January 2002. U.S. academic economists concentrated on whether a single currency was a good or bad thing, usually using the theory of optimu

ISL1 is a major susceptibility gene for classic bladder exstrophy and a regulator of urinary tract development

Previously genome-wide association methods in patients with classic bladder exstrophy (CBE) found association with ISL1, a master control gene expressed in pericloacal mesenchyme. This study sought to further explore the genetics in a larger set of patients following-up on the most promising genomic regions previously reported. Genotypes of 12 markers obtained from 268 CBE patients of Australian,

The great financial crisis in Finland and Sweden : The nordic experience of financial liberalization

The book compares and contrasts the experiences of Finland and Sweden, then adopts an international perspective, encompassing the experiences of Asia, Latin America, Denmark and Norway. Lessons from the 1990s crisis are drawn, and possible solutions prescribed. The conclusion is that long-term effects of financial crises – financial liberalization and integration – are not as dramatic as the short

Experimental and theoretical oscillator strengths of Mg i for accurate abundance analysis

Context. With the aid of stellar abundance analysis, it is possible to study the galactic formation and evolution. Magnesium is an important element to trace the α-element evolution in our Galaxy. For chemical abundance analysis, such as magnesium abundance, accurate and complete atomic data are essential. Inaccurate atomic data lead to uncertain abundances and prevent discrimination between diffe
