The Many Dimensions of a Crisis

The many dimensions of a crisis:A crisis is an event that can have very negative consequences, which can sometimes be long term or even permanent. In the media, there are regular references to a “climate crisis”, “refugee crisis” or “health crisis”. But, what does the term “crisis” actually mean? And can a deepened understanding of crises contribute to future humanitarian initiatives?

Krisens många dimensioner

Krisens många dimensioner:En kris är en händelse som kan få väldigt negativa konsekvenser – som ibland kan bli långvariga eller till och med permanenta. I dagens mediedebatt talas det regelbundet om ”klimatkris”, ”flyktningkris” och ”hälsokris”. Men vad betyder egentligen begreppet kris? Och kan en fördjupad förståelse av krisens bidra till framtida humanitärt arbete?

IEEE Std. P1687.1 for Access Control of Reconfigurable Scan Networks

We address access control of reconfigurable scan networks, like IEEE Std. 1687 networks. We propose an on- chip test block to perform: (1) test for faulty scan-chains, (2) localization of faulty scan-chains and (3) repair by excluding faulty scan-chains, and an access control block to (1) control so scan- chains (instruments) are only accessed in allowed combinations, (2) detection of access attem

Role of Thermal Equilibrium Dynamics in Atomic Motion during Nonthermal Laser-Induced Melting

This study shows that initial atomic velocities as given by thermodynamics play an important role in the dynamics of phase transitions. We tracked the atomic motion during nonthermal laser-induced melting of InSb at different initial temperatures. The ultrafast atomic motion following bond breaking can in general be governed by two mechanisms: the random velocity of each atom at the time of bond b

Structure of two-dimensional Fe3O4

We have investigated the structure of an ultrathin iron oxide phase grown on Ag(100) using surface X-ray diffraction in combination with Hubbard-corrected density functional theory (DFT+U) calculations. The film exhibits a novel structure composed of one close-packed layer of octahedrally coordinated Fe2+ sandwiched between two close-packed layers of tetrahedrally coordinated Fe3+ and an overall s
