Homogeneous charge compression ignition (HCCI) is a potentially attractive operating mode for stationary natural gas engines. Increasing demand for efficient, clean burning engines for electrical power generation provides an opportunity to utilize HCCI combustion if several inherent difficulties can be overcome. Fuel composition, particularly the higher hydrocarbon content (ethane, propane, and bu

Cosmological investigations, using high-redshift quasi-stellar object (QSO) absorption spectra, of possible variations of the fine-structure constant (alpha) require very accurate laboratory wavelengths for a number of resonance transitions from several different species. A change in alpha could be detected as a shift in the wavelengths of atomic transitions in the QSO systems and to accurately de

A number of Extremely Large Telescopes for visual-infrared and adjacent wavelengths are in various degrees of progress. All have primary mirrors with equivalent diameters larger than 20 m and are intended for operation with adaptive optics systems. We discuss several ELT observing parameters as functions of wavelength. Stellar energy distributions and atomic line spectra are inspected as are the t

Övergången från den medeltida kyrkoårskalendariska dateringstypen till den nutida månadskalendariska kartläggs kvantitativt för danska och svenska i ett senmedeltida och 1500-tals-material. Också utvecklingen med hänsyn till de båda typernas struktur undersöks.

The high-resolution X-ray crystal structures of the carbohydrate recognition domain of human galectin-3 were solved in complex with N-acetyllactosamine (LacNAc) and the high-affinity inhibitor, methyl 2-acetamido-2-deoxy-4-O-(3-deoxy-3-[4-methoxy-2,3,5,6-tetrafluorobenzamido]--D-galactopyranose)--D-glucopyranoside, to gain insight into the basis for the affinity-enhancing effect of the 4-methoxy-2

We propose a simple architecture for implementing supervised neural network models optically with photorefractive technology. The architecture is very versatile: a wide range of supervised learning algorithms can be implemented including mean-field-theory, backpropagation, and Kanerva-style networks. Our architecture is based on a single crystal with spatial multiplexing rather than the more commo

This paper examines the influence of artificial intelligence (AI) on recent operatic practice, exploring its potential to affect the development of the genre from the artist’s perspective. While opera has historically evolved in tandem with technological advancements, the integration of AI raises important questions about its function within the operatic toolbox and its relation to the genre’s cor

Objective Ultrasound is a promising tool to foster much-needed improvement of skin assessment in systemic sclerosis (SSc). Our aim was to develop evidence and expert opinion-based recommendations to promote the standardisation and harmonisation of technical execution and reporting of skin ultrasound studies in SSc. Methods A multidisciplinary task force of 16 members from five European countries a

This chapter explores how algorithms produce aesthetic forms and dystopian configurations across Palestinian cyber and digital spaces. Through surveillance and erasure, algorithms operate as infrastructures of (in)visibility across social media and digital maps. While serving the Israeli system of control by making Palestinian users and contents hyper-visible to surveillance, algorithms ultimately

The remaining lifetime of concrete structures subjected to chloride-induced corrosion has been studied in many papers. However, few studies so far consider explicitly experiences from case studies, jointly several corrosion mechanisms and a system perspective. This paper introduces a methodology to evaluate the time-dependent system reliability for concrete bridges subjected to reinforcement corro

Within a UN Joint Programme titled “Enhancing the Capacity of Turkey to Adapt to Climate Change” a systems approach workshop was carried out in Adana, Turkey with broad stakeholder participation. The participants applied systems thinking approach, causal loop diagramming methodology and systems analysis to examine the potential impacts of projected climatic changes on natural ecosystems and socio-

Forskare vid Lunds universitet har upptäckt ett cellskelett som ger struktur åt mito-kondrierna, cellens energifabriker. Skelettet är nödvändigt för mitokondriernas funktion, men forskarna fann även att cancerceller trots defekter utnyttjar skelettet för att kunna bibehålla sin energiproduktion – och därigenom överleva. Cellskelettet i mitokondrierna fungerar ungefär som ett armeringsnät och hjälp
