The problem of synthesizing network-decentralized observers arises when several agents, corresponding to the nodes of a network, exchange information about local measurements to asymptotically estimate their own state. The network topology is unknown to the nodes, which can rely on information about their neighboring nodes only. For homogeneous systems, composed of identical agents, we show that a
A novel detection algorithm with an efficient VLSI architecture featuring efficient operation over infinite complex lattices is proposed. The proposed design results in the highest throughput, the lowest latency, and the lowest energy compared to the complex-domain VLSI implementations to date. The main innovations are a novel complex-domain means of expanding/visiting the intermediate nodes of th
In this paper, a novel hard-output detection algorithm for the complex multiple-input multiple-output (MIMO) detectors is proposed, which results in a significant throughput enhancement, a near-ML performance, and an SNR-independent fixed-throughput. Moreover, a high-throughput VLSI implementation is proposed, which is based on a novel method of the node generation and sorting scheme. The proposed
Background: Serial transverse enteroplasty facilitates weaning from parenteral support in selected patients with short bowel syndrome, although repeated procedure is frequently required. Our aim was to evaluate the outcome of a series of patients after serial transverse enteroplasty and define predictors of repeated serial transverse enteroplasty and weaning off parenteral support. Methods: All ch
This report outlines the potential for a more structured and strategic relationship between the European Union and the Islamic Republic of Iran following the Joint Comprehensive Plan of Action (JCPOA). To both address areas of disagreement and complaints, as well as pursue common interests and matters of mutual benefit, the EU needs to put in place an institutional framework that can withstand the
In most studies on technology change, the analysis of cost reductions of new energy technologies has been narrow and has often neglected essential processes related to the deployment of new technologies, such as photovoltaics (PV). However, in the case of distributed PV systems, other costs than for the PV modules – aka the deployment or balance-of-system costs – are significant. This review study
Background: This is an update of the Cochrane review published in 2002. Colorectal cancer (CRC) is a major cause of morbidity and mortality in industrialised countries. Experimental evidence has supported the hypothesis that dietary fibre may protect against the development of CRC, although epidemiologic data have been inconclusive. Objectives: To assess the effect of dietary fibre on the recurren
The concept of a bioeconomy can be understood as an economy where the basic building blocks for materials, chemicals, and energy are derived from renewable biological resources. Biorefineries are considered an integral part of the development toward a future sustainable bioeconomy. The purpose of this literature review is to synthesize current knowledge about how biorefinery technologies are being
Tumors are phenotypically heterogeneous and include subpopulations of cancer cells with stemlike properties. The natural product salinomycin, a K+-selective ionophore, was recently found to exert selectivity against such cancer stem cells. This selective effect is thought to be due to inhibition of the Wnt signaling pathway, but the mechanistic basis remains unclear. Here, we develop a functionall
Laminin α2 chain-deficient muscular dystrophy, or LAMA2-CMD, is a very severe disease caused by mutations in the LAMA2 gene. Skeletal muscle is the most affected tissue, with patients presenting symptoms such as hypotonia at birth, joint contractures and progressive muscle wasting. Changes in the central nervous system include white matter abnormalities, delayed motor milestones and compromised ac
Extracting microanatomical information beyond the image resolution of MRI would provide valuable tools for diagnostics and neuroscientific research. A number of mathematical models already suggest microstructural interpretations of diffusion MRI (dMRI) data. Examples of such microstructural features could be cell bodies and neurites, e.g. the axon's diameter or their orientational distribution for
The ATLAS luminosity monitor, LUCID (LUminosity Cherenkov Integrating Detector), had to be upgraded for the second run of the LHC accelerator that started in spring 2015. The increased energy of the proton beams and the higher luminosity required a redesign of LUCID to cope with the more demanding conditions. The novelty of the LUCID-2 detector is that it uses the thin quartz windows of photomulti
Given the growing importance of bike-sharing systems nowadays, in this paper we suggest an alternative approach to mitigate the most crucial problem related to them: the imbalance of bicycles between zones owing to one-way trips. In particular, we focus on the emerging free-floating systems, where bikes can be delivered or picked-up almost everywhere in the network and not just at dedicated dockin
Most microalgal species are geographically widespread, but little is known about how they are dispersed. One potential mechanism for long-distance dispersal is through birds, which may transport cells internally (endozoochory) and deposit them during, or in-between, their migratory stopovers. We hypothesize that dinoflagellates, in particular resting stages, can tolerate bird digestion; that bird
