Palaeozoic 'conodont pearls' and other phosphatic micro-spherules

Sub-millimetre-sized phosphatic spherules are often found in acetic acid-insoluble residues produced for microfossil extraction. As they are typically associated with conodont elements and have a similar chemical composition, they are informally known as 'conodont pearls'. Still, the origin of these micro-spherules has been controversial, and authors have disagreed regarding their mode of formatio

Metropolis-hastings improved particle smoother and marginalized models

This paper combines the Metropolis-Hastings Improved Particle Smoother (MHIPS) with marginalized models. It demonstrates the effectiveness of the combination by looking at two examples; a degenerate model of a double integrator and a fifth order mixed linear/nonlinear Gaussian (MLNLG) model. For the MLNLG model two different methods are compared with the non-marginalized case; the first marginaliz

Control considerations of the low cost prosthetic Touch Hand

The control of the Touch Hand: a low-cost electrically powered prosthetic hand is explored in this paper. A novel Haptic User Interface is proposed and tested as a supplement for amputee-prosthetic EMG control. The performance of the prosthetic hand is tested through gripping tests. The hand is capable of performing a lateral grip of 3.7 N, a power grip of 19.5 N and to passively hold a weight of

Living the neurochemical self? : Experiences after the success of the SSRIs

This is an exploration, in dialogue with Nikolas Rose’sconceptualization of the neurochemical self, of how people takingantidepressants through in-depth interviews make sense of theirexperiences of using selective serotonin reuptake inhibitors.

Automatic hand phantom map detection methods

Many amputees have maps of referred sensation from their missing hand on their residual limb (phantom maps). This skin area can serve as a target for providing amputees with tactile sensory feedback. Providing tactile feedback on the phantom map can improve the object manipulation ability, enhance embodiment of myoelectric prostheses users and help reduce phantom limb pain. The distribution of the

A 2.7-GHz multi-level PWM carrier-bursting RF transmitter

Carrier-bursting is an attractive RF transmitter concept to achieve high efficiency. The power amplifier (PA) itself either operates at its peak efficiency or is turned off. Another efficiency-enhancing approach is the Doherty concept, where the main PA reaches its peak efficiency already in back-off and the peak PA contributes at high input levels to reach the desired output power. In this work,

Multiple cryptic species of sympatric generalists within the avian blood parasite Haemoproteus majoris

The avian haemosporidian parasite Haemoproteus majoris has been reported to infect a wide range of passerine birds throughout the Holarctic ecozone. Five cytochrome b (cyt b) lineages have been described as belonging to the morphological species H. majoris, and these form a tight phylogenetic cluster together with 13 undescribed lineages that differ from each other by < 1.2% in sequence divergence

Melissa Aronczyk, Branding the Nation: The Global Business of National Identity

Melissa Aronczyk’s Branding the Nation is a watershed moment for the field of nation brands research. Published by the highly respected Oxford University Press, it is the first critical monograph on the topic to achieve mainstream recognition, as evidenced by a review in the Times Higher Education supplement. Drawing on over a decade of research and advertising industry experience, 100 interviews

The Future of U.S. Public Diplomacy: An Uncertain Fate, Kathy R. Fitzpatrick

‘The Future of U.S. Public Diplomacy’ is a welcome addition to critical studies within the field of public diplomacy (PD) by public relations (PR) scholar Kathy Fitzpatrick. The monograph aims to untangle many of PD’s historical misconceptions and contribute to the development of its conceptual foundations through an examination of the U.S. experience. In truth, the interaction between the discuss

Introduction

This volume originated out of a discussion with the British Council a few years ago. In light of changes to their grant-in-aid in 2010, nearly two thirds of their governmental funding is now comprised of Official Development Assistance (oda). I asked what difference there was between the work that was conducted as cultural relations and the work that was budgeted as aid. The answer was that the sa

Subjective rhythmization : A replication and an assessment of two theoretical explanations

Subjective rhythmization is that phenomenon whereby, when one is listening to a monotone metronome sequence, some sounds are experienced as accented. These subjectively accented sounds group the sequence similarly to how the metrical structure of a piece of music groups the beats. Subjective rhythmization was first investigated by Bolton (1894); the present study aims at replicating and extending

GRP75 upregulates clathrin-independent endocytosis through actin cytoskeleton reorganization mediated by the concurrent activation of Cdc42 and RhoA

Therapeutic macromolecules are internalized into the cell by either clathrin-mediated endocytosis (CME) or clathrin-independent endocytosis (CIE). Although some chaperone proteins play an essential role in CME (e.g. Hsc70 in clathrin uncoating), relatively few of these proteins are functionally involved in CIE. We previously revealed a role for the mitochondrial chaperone protein GRP75 in heparan

Accented cinema and beyond : Latin American minor cinemas in Sweden, 1970 - 1990

The aim of this article is to map and present professional and non-professional Latin American film-making that took place in Sweden from the early 1970s to the early 1990s. Most of the films from this period have been excluded from the established, canonical film history, both nationally and internationally. Another aim of the article is to argue for the importance of the concept of ‘minor cinema

Dietary and environmental implications of Early Cretaceous predatory dinosaur coprolites from Teruel, Spain

Coprolites from the Early Cretaceous vertebrate bone-bed at Ariño in Teruel, Spain, were analyzed geochemically and palynologically. They contain various inclusions, such as small bone fragments, abundant plant remains, pollen, and spores. We attribute the coprolites to carnivorous dinosaurs based partly on their morphology together with the presence of bone fragments, and a high content of calciu

The mouthparts enriched odorant binding protein 11 of the Alfalfa Plant Bug Adelphocoris lineolatus displays a preferential binding behavior to host plant secondary metabolites

Odorant binding proteins (OBPs) are proposed to be directly required for odorant discrimination and represent potential interesting targets for pest control. In the notoriously agricultural pest Adelphocoris lineolatus, our previous functional investigation of highly expressed antennal OBPs clearly supported this viewpoint, whereas the findings of the current study by characterizing of AlinOBP11 r

Robust Feedback Stability of Negative Imaginary Systems: An Integral Quadratic Constraint Approach

Sufficient conditions for stability of feedback interconnections of negative imaginary systems are derived via an integral quadratic constraint (IQC) approach. These extend existing results in the literature by exploiting the flexibility present at the static and infinite frequencies to reduce conservatism. Negative imaginary transfer functions with poles on the imaginary axis are accommodated usi

Assimilation of satellite observations for the estimation of Savanna gross primary production

Monitoring vegetation gross primary production (GPP) is required for both carbon balance studies and early warning systems aiming to detect unfavorable crop and pasture conditions. This manuscript describes the assimilation of MODIS observations by a simple process model, fed by meteorological data (temperature, incident radiation and rainfall) and linked with a canopy reflectance model, to estima

Scanning electron microscopy analysis of the antennal sensilla in therare saproxylic beetle Elater ferrugineus (Coleoptera: Elateridae)

This work provides the first morphological analysis (both at gross and fine level) of the antennal structures in the genusElater (Coleoptera, Elateridae). The typology, number and distribution patterns of the antennal sensilla in the rare saproxylicElater ferrugineus (both male and female) were studied using scanning electron microscopy (SEM). The serrate antennae ofE. ferrugineus consisted of a s
