Advantage of Binary Stochastic synapses for hardware Spiking Neural Networks with realistic memristors
Hardware implementing spiking neural networks (SNNs) has the potential to provide transformative gains in energy efficiency and throughput for energy-restricted machine-learning tasks. This is enabled by large arrays of memristive synapse devices that can be realized by various emerging memory technologies. But in practice, the performance of such hardware is limited by non-ideal features of the me
EAT-Lancetkosten undersökt i svensk studie
Bloggpost på nutritionsfakta.se.EAT-Lancetkommissionen lanserade 2019 sin ”the great food transformation”, en modell för hälsosamma matvanor för en växande global befolkning som skulle hålla livsmedelssystemet inom planetens gränser.En uppföljande svensk studie har tagit fram ett eget index för att mäta följsamheten till EAT-Lancetkosten, med en poängsättning som gör det möjligt att se hur väl en
Counterintuitive Electrostatics upon Metal Ion Coordination to a Receptor with Two Homotopic Binding Sites
The consecutive binding of two potassium ions to a bis(18-crown-6) analogue of Tröger’s base (BCETB) in water was studied by isothermal titration calorimetry using four different salts, KCl, KI, KSCN, and K2SO4. A counterintuitive result was observed: the enthalpy change associated with the binding of the second ion is more negative than that of the first (ΔH°bind,2 < ΔH°bind,1). This remarkable f
Knowledge discoveryweb service for spatial data infrastructures
The size, volume, variety, and velocity of geospatial data collected by geo-sensors, people, and organizations are increasing rapidly. Spatial Data Infrastructures (SDIs) are ongoing to facilitate the sharing of stored data in a distributed and homogeneous environment. Extracting high-level information and knowledge from such datasets to support decision making undoubtedly requires a relatively so
Voluntary Global Business Initiatives and the International Climate Negotiations : A Case Study of the Greenhouse Gas Protocol
The past few years have witnessed the emergence of a plethora of transnational climate governance experiments. They have been developed by a broad range of actors, such as cities, non-profit organizations, and private corporations. Several scholars have lately devoted particular attention to voluntary global business initiatives in the policy domain of climate change. Their studies have provided c
The 6G Computing Continuum (6GCC): Meeting the 6G computing challenges
6G systems, such as Large Intelligent Surfaces, will require distributed, complex, and coordinated decisions throughout a very heterogeneous and cell free infrastructure. This will require a fundamentally redesigned software infrastructure accompanied by massively distributed and heterogeneous computing resources, vastly different from current wireless networks.To address these challenges, in this6G systems, such as Large Intelligent Surfaces, will require distributed, complex, and coordinated decisions throughout a very heterogeneous and cell free infrastructure.

Exceptional points in anisotropic planar microcavities
Planar microcavities allow the control and manipulation of spin polarization, manifested in phenomena like the optical spin Hall effect due to the intrinsic polarization mode splitting. Here, we study a transparent microcavity with broken rotational symmetry, realized by aligning the optic axis of a uniaxial cavity material in the cavity plane, giving rise to exceptional points in the dispersion r
Disturbance-based management of ecosystem services and disservices in partial nitritation-anammox biofilms
The resistance and resilience provided by functional redundancy, a common feature of microbial communities, is not always advantageous. An example is nitrite oxidation in partial nitritation-anammox (PNA) reactors designed for nitrogen removal in wastewater treatment, where suppression of nitrite oxidizers like Nitrospira is sought. In these ecosystems, biofilms provide microhabitats with oxygen g
Prediction of Postoperative Delirium After Cardiac Surgery with A Quick Test of Cognitive Speed, Mini-Mental State Examination and Hospital Anxiety and Depression Scale
Purpose: To evaluate if preoperative assessment with A Quick Test of Cognitive Speed (AQT) could increase the accuracy of predicting delirium after cardiac surgery compared to Mini-Mental State Examination (MMSE), and examine if a composite of variables, including cognitive function and depressive symptoms, could be useful to predict delirium. Patients and Methods: Cardiac surgery was performed in
On the Universality of Spatially Coupled LDPC Codes over Intersymbol Interference Channels
In this paper, we derive the exact input/output transfer functions of the optimal a-posteriori probability channel detector for a general ISI channel with erasures. Considering three channel impulse responses of different memory as an example, we compute the BP and MAP thresholds for regular spatially coupled LDPC codes with joint iterative detection and decoding. When we compare the results with
Setting Up a Big Data Project : Challenges, Opportunities, Technologies and Optimization
In the first part of this chapter we illustrate how a big data project can be set up and optimized. We explain the general value of big data analytics for the enterprise and how value can be derived by analyzing big data. We go on to introduce the characteristics of big data projects and how such projects can be set up, optimized and managed. Two exemplary real word use cases of big data projects

A secondary aim was to estimate the same-sex sexuality attributable fractions.DesignA population-based cross-sectional survey.SettingSouthern Sweden.Participants2968 respondents out of 7000 youth and young adults between
Personalized Dietary Recommendations Based on Lipid-Related Genetic Variants : A Systematic Review
Background: Obesity and dyslipidemias are risk factors for developing cardiovascular diseases, the leading causes of morbidity and mortality worldwide. The pathogenesis of these diseases involves environmental factors, such as nutrition, but other aspects like genetic polymorphisms confer susceptibility to developing obesity and dyslipidemias. In this sense, nutrigenetics is being used to study th
Editorial: developments at the Annals of regional science 2020–2021
The editors-in-chief of the Annals of Regional Science offer an overview and analysis of recent developments at the journal from January 2020 through December 2021, a time period hampered by the COVID-19 pandemic. Annal’s Impact Factor increased substantially to 2.646 in 2020. Moreover, submissions increased from pre-COVID times. A new development is the shifting of source regions for articles acc
Prospective association between dietary pesticide exposure profiles and type 2 diabetes risk in the NutriNet-Santé cohort
BackgroundStudies focusing on dietary pesticides in population-based samples are scarce and little is known about potential mixture effects. We aimed to assess associations between dietary pesticide exposure profiles and Type 2 Diabetes (T2D) among NutriNet-Santé cohort participants.MethodsParticipants completed a Food Frequency Questionnaire at baseline, assessing conventional and organic food co
Cardiac Long-Axis Function. Experimental and Clinical Aspects.
This thesis includes both experimental and clinical projects. The experimental studies investigate pathophysiological aspects of ventricular longitudinal function and therapeutic hypothermia during acute myocardial infarction (AMI). The clinical projects investigate the ability of ventricular longitudinal function variables to predict mortality and morbidity in patients with heart failure and redu
The influence of hydrodynamic damping on the motion of an immersed elastic cantilever
A fluid–structure interaction (FSI) technique is applied to study the influence of hydrodynamic damping on the motion of a cantilever in a still tank. The FSI is performed by a partitioned technique, using the deal.II and OpenFOAM open-source packages. An incompressible flow solver is applied for the fluid and a compressible solver for the structure. The motion of the structure is generated by app
Inner-Shell-Ionization-Induced Femtosecond Structural Dynamics of Water Molecules Imaged at an X-Ray Free-Electron Laser
The ultrafast structural dynamics of water following inner-shell ionization is a crucial issue in high-energy radiation chemistry. We have exposed isolated water molecules to a short X-ray pulse from a free-electron laser and detected momenta of all produced ions in coincidence. By combining experimental results and theoretical modeling, we can image dissociation dynamics of individual molecules i
