An understanding of how helper T cells are activated to drive blood group immune responses will help to explain the immunogenicity of antigens such as HPA-1a. In this issue of Blood, Anani Sarab and colleagues identify the naturally processed HPA1a peptides recognized by T cells and set the stage for peptide-based therapies in NAIT.(1).
BACKGROUND: Transfusion-related immunomodulation (TRIM) has been correlated with the presence of white cells (WBCs) in blood transfusions, but the role of components such as platelets (PLTs) in mediating TRIM has not been extensively examined. We designed a murine PLT transfusion model to study whether leukoreduced PLTs mediate TRIM effects.STUDY DESIGN AND METHODS: CBA recipient mice were adminis
PURPOSE: Autologous platelet gels can be prepared using the patient's own platelet-rich plasma and thrombin produced by the Thrombin Processing Device (Thermogenesis Corp, Rancho Cordova, CA). As the Thrombin Processing Device thrombin contains a residual amount of ethanol, the purpose of this study was to investigate the effect of the Thrombin Processing Device thrombin on growth factor release f
We perform fully bipolar Monte Carlo simulations of electrons and holes in III-Nitride multi-quantum well light-emitting diodes (LEDs) to investigate the effects of hot carriers. Our results show how accounting for hot carriers affects the current-voltage characteristics and device efficiency. We also discuss the effects of bandstructure details on the simulation results. Further simulations with
Diffusion-driven current transport (DDCT) has recently been proposed as a new way to organize the current injection in nanoscale optoelectronic devices. The very recent first proof-of-principle experiments have also shown that DDCT works as predicted theoretically. In this work we perform simulations on DDCT-based III-Nitride devices and demonstrate how the optimization of DDCT differs significant
In this paper a multichannel subspace detector is proposed based on a separable spatio-temporal linear model. The generalized likelihood ratio test (GLRT) for this model is derived for the case of coloured Gaussian noise and known temporal and covariance matrices. Simulation results support the theory and illustrate the benefits of the spatio-temporal detector versus channel-by-channel detectors f
Negotiation can be seen as a dynamic social process. Perspectives emphasizing the social context and dynamics of negotiations have been largely neglected in the negotiation literature. This article addresses the question of why social relations have received such scant attention, reviews the existing literature on negotiation as a social process, and spells out some ingredients of a social context
Industrial robotics is a complex domain, not easily amenable to formalization using semantic technologies. It involves such disparate aspects of the real world as geometry, dynamics, constraint-satisfaction, planning and scheduling, real-time control, robot-robot and human-robot communication and, finally, intentions of the robot user. To represent so different kinds of knowledge is a challenge an
The aim for this article is to outline a typology of iconicity in verse, ranging from Form miming form to Meaning miming form/meaning. Verse here means the occurrence of rhythmical devices, such as meter, and the division into lines and stanzas. As a starting point, the different possible appearances of 'representamens' in mainly twentieth-century poetry will be discussed, following Elleström's (2
A sub-area of business analytics increasingly growing in prominence is social media analytics (SMA), which is not surprising given the large volume of data and content generated daily in social media. Despite the growing interest, given the vastness of the area, there is little understanding of the topics and issues with respect to SMA that should be investigated by IS researchers. In an effort to
We present an overview of the options for diffraction implemented in the general-purpose event generator PYTHIA8. We review the existing model for low- and high-mass soft diffraction and present a new model for hard diffraction in pp and pp¯ collisions. Both models use the Pomeron approach pioneered by Ingelman and Schlein, factorising the single diffractive cross section into a Pomeron flux and a
The generation of new mobile devices and the need to make decisions 'on the move' led to a new technology coined as mobile business intelligence (m-BI). M-BI is different from traditional BI in terms of user profiles, level of analytics and functionalities. Although there is a growing interest from both practitioners and academics, very little is known about m-BI in general and even less on its us
A study of tonality and modality in contemporary dance music and the thoughts on aural training related to said genre.
Background Environmental barriers increase risk for mobility difficulties in old age. Mobility difficulty is preceded by a phase where people try to postpone a difficulty through mobility modification. We studied whether perceived environmental mobility barriers outdoors correlate with mobility modification and mobility difficulty, predict development of mobility difficulty over a two-year follow-
