Many application areas for embedded systems, such as DSP, media coding, and image processing, are based on stream processing. Stream programs in these areas are often naturally described as graphs, where nodes are computational kernels that send data over the edges. This structure also exhibits large amounts of concurrency, because the kernels can execute independently as long as there are data to

We implemented a functional neuronal network that was able to learn and discriminate haptic features from biomimetic tactile sensor inputs using a two-layer spiking neuron model and homeostatic synaptic learning mechanism. The first order neuron model was used to emulate biological tactile afferents and the second order neuron model was used to emulate biological cuneate neurons. We have evaluated

Human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) can be differentiated into many different cell types of the central nervous system. One challenge when using pluripotent stem cells is to develop robust and efficient differentiation protocols that result in homogenous cultures of the desired cell type. Here, we have utilized the SMAD-inhibitors SB431542 and Noggin in a

Specialized epitope tags are widely used for detecting, manipulating or purifying proteins, but often their versatility is limited. Here, we introduce the ALFA-tag, a rationally designed epitope tag that serves a remarkably broad spectrum of applications in life sciences while outperforming established tags like the HA-, FLAG®- or myc-tag. The ALFA-tag forms a small and stable α-helix that is func

Mistra Future Fashion Phase 2, IVL Swedish Environment Institute (IVL), PlanMiljø and the International Institute of Industrial Environmental Economics (IIIEE) at Lund University have investigated a selection of important aspects to consider when implementing an Extended Producer Responsibility (EPR) for textiles in Sweden. The focus of the work was to identify, analyse and promote aspects that co

The involvement of sodium/potassium-ATPase in regulating parathyroid hormone (PTH) secretion is inferred from in vitro studies. Recently, the α-klotho-dependent rapid recruitment of this ATPase to the parathyroid cell plasma membrane in response to low extracellular calcium ion was suggested to be linked to increased hormone secretion. In this study, we used an in vivo rat model to determine the i

Pax Syriana provides readers with a broad picture of what has changed, and what has failed to change, in the Lebanese political system after the end of the civil war.

The ability of men to remain fertile throughout their lives depends upon establishment of a spermatogonial stem cell (SSC) pool from gonocyte progenitors, and thereafter balancing SSC renewal vs terminal differentiation. Here, we report that precise regulation of the cell cycle is crucial for this balance. Whereas cyclin-dependent kinase 2 (Cdk2) is unnecessary for mouse viability or gametogenesis

The primary function of language is to communicate-that is, to make individuals reach a state of mutual understanding about a particular thought or idea. Accordingly, daily communication is truly a task of social coordination. Indeed, successful interactions require individuals to (1) track and adopt a partner's perspective and (2) continuously shift between the numerous elements relevant to the e

Currently, there is an intensive development of bio-based aromatic building blocks to replace fossil-based terephthalates used for poly(ethylene terephthalate) production. Indole is a ubiquitous aromatic unit in nature, which has great potential as a bio-based feedstock for polymers or plastics. In this study, we describe the synthesis and characterization of new indole-based dicarboxylate monomer

The first synthesis of a non-uniformly deuterium labelled 21mer RNA is reported using our ‘NMR-window’ concept, showing its unique application in the unambiguous NMR assignment of the non-exchangeable aromatic and sugar protons.

Background and study aims Endoscopic submucosal dissection (ESD) allows en bloc resection of large colorectal lesions but ESD experience is limited outside Asia. This study evaluated implementation of ESD in the treatment of colorectal neoplasia in a Western center. Patients and methods Three hundred and one cases of colorectal ESD (173 rectal and 128 colonic lesions) were retrospectively evaluate

Herein we describe the discovery of ACP-105 (1), a novel and potent nonsteroidal selective androgen receptor modulator (SARM) with partial agonist activity relative to the natural androgen testosterone. Compound 1 was developed from a series of compounds found in a HTS screen using the receptor selection and amplification technology (R-SAT). In vivo, 1 improved anabolic parameters in a 2-week chro

One of the most important trends in contemporary tourism is the increase in urban tourism, both in absolute and in relative terms. In some destinations, e.g. Barcelona, the pressure from tourism on local resources such as housing and urban space has reached a point where we begin to speak about overtourism. The development of overtourism is related to decreasing relative costs of travel, e.g. low-

Dietary components in early life play a role in both microbiota and intestinal immune system maturation in mammalian species. Adipokines, as endogenously produced hormones from breast milk, may have an impact on this process. The aim of the present study was to establish the influence of leptin and adiponectin supplementation during suckling on the intraepithelial lymphocyte composition, intestina
