A Transmon Quantum Annealer: Decomposing Many-Body Ising Constraints Into Pair Interactions [article]

Martin Leib, Peter Zoller, Wolfgang Lechner
2016 arXiv   pre-print
Adiabatic quantum computing is an analog quantum computing scheme with various applications in solving optimization problems. In the parity picture of quantum optimization, the problem is encoded in local fields that act on qubits which are connected via local 4-body terms. We present an implementation of a parity annealer with Transmon qubits with a specifically tailored Ising interaction from Josephson ring modulators.

Lifestyle factors and high-risk atherosclerosis: Pathways and mechanisms beyond traditional risk factors

Katharina Lechner, Clemens von Schacky, Amy L McKenzie, Nicolai Worm, Uwe Nixdorff, Benjamin Lechner, Nicolle Kränkel, Martin Halle, Ronald M Krauss, Johannes Scherr
2019 European Journal of Preventive Cardiology  
Despite major efforts to reduce atherosclerotic cardiovascular disease (ASCVD) burden with conventional risk factor control, significant residual risk remains. Recent evidence on non-traditional determinants of cardiometabolic health has advanced our understanding of lifestyle–disease interactions. Chronic exposure to environmental stressors like poor diet quality, sedentarism, ambient air pollution and noise, sleep deprivation and psychosocial stress affect numerous traditional and

These include body composition, cardiorespiratory fitness, muscle strength and functionality and the intestinal microbiome, which are increasingly recognized as major determinants of cardiovascular health. Evidence points to partially overlapping mechanisms, including effects on inflammatory and nutrient sensing pathways, endocrine signalling, autonomic function and autophagy. Of particular relevance is the potential of low-risk lifestyle factors to impact on plaque vulnerability through altered adipose tissue and skeletal muscle phenotype and secretome. Collectively, low-risk lifestyle factors cause a set of phenotypic adaptations shifting tissue cross-talk from a proinflammatory milieu conducive for high-risk atherosclerosis to an anti-atherogenic milieu. The ketone body ß-hydroxybutyrate, through inhibition of the NLRP-3 inflammasome, is likely to be an intermediary for many of these observed benefits. Adhering to low-risk lifestyle factors adds to the prognostic value of optimal risk factor management, and benefit occurs even when the impact on conventional risk markers is discouragingly minimal or not present. The aims of this review are (a) to discuss novel lifestyle risk factors and their underlying biochemical principles and (b) to provide new perspectives on potentially more feasible recommendations to improve long-term adherence to low-risk lifestyle factors.

Blackthorn: Latency Estimation Framework for CNNs on Embedded Nvidia Platforms

Martin Lechner, Axel Jantsch
2021 IEEE Access  
With more powerful yet efficient embedded devices and accelerators being available for Deep Neural Networks (DNN), machine learning is becoming an integral part of edge computing. As the number of such devices increases, finding the best platform for a specific application has become more challenging. A common question for application developers is to find the most cost-effective combination of a DNN and a device while still meeting latency and accuracy requirements. In this work, we propose
more » ... ckthorn, a layerwise latency estimation framework for embedded Nvidia GPUs based on analytical models. We provide accurate predictions for each layer, helping developers to find bottlenecks and optimize the architecture of a DNN to fit target platforms. Our framework can quickly evaluate and compare large amounts of network optimizations without needing to build time-consuming execution engines. Our experimental results on Jetson TX2 and Jetson Nano devices show a per-layer estimation error of 6.104% Root-Mean-Square-Percentage-Error (RMSPE) and 5.888% RMSPE, which significantly outperforms current state-of-the-art methods. At network level, the average latency error is below 3% for the tested DNNs.

Amino Terminal pro B-Type Natriuretic Peptide Levels Are Elevated in the Cord Blood of Neonates With Congenital Heart Defect

2009 Pediatric Research  
This prospective study investigates whether amino terminal proB-type natriuretic peptide (NT-proBNP) levels are elevated in neonates with congenital heart defect (CHD). NT-proBNP levels in the umbilical cord blood of 60 neonates with prenatally diagnosed CHD, in the cord blood of 200 control subjects, and in the plasma of the respective mothers were analyzed using an automated enzyme immunoassay. NT-proBNP concentrations in the cord blood of the CHD group were significantly elevated compared

The NT-proBNP concentrations of the newborns and their mothers did correlate neither in the CHD nor in the control group. In 54 patients with CHD, NT-proBNP levels were measured on the median 5th day of life. They showed a significant increase (median 1665 pg/mL and 19222 pg/mL; p Ͻ 0.001). NT-proBNP levels in the cord blood of neonates with CHD are significantly elevated and show a marked increase in the first week of life. Furthermore, this study confirms previously published reference intervals of NT-proBNP in the cord blood of healthy neonates as well as the finding that there is no exchange of NT-proBNP across the placenta.
