Many real world systems are at risk of undergoing critical transitions, leading to sudden qualitative and sometimes irreversible regime shifts. The development of early warning signals is recognized as a major challenge. Recent progress builds on a mathematical framework in which a real-world system is described by a low-dimensional equation system with a small number of key variables, where th...

The majority of lumbar spine syndromes encountered in clinical practice result from mechanical – activity-related – disorders. They can be classified into dural, ligamentous and stenotic syndromes. Lumbar syndromes, however, can also stem from non-mechanical – non-activity-related – disorders affecting the spine. These are: inflammatory diseases, both septic and rheumatological; tumours and inf...

Seven names 1 condition! The definition of sleep apnoea can be confusing because it is described in research literature under many guises: Obstructive Sleep apnoea (OSA) Sleep Apnoea (SA) Obstructive Sleep Apnoea Syndrome (OSAS) Sleep Apnoea/Hypopnoea Syndrome (SAHS) Obstructive Sleep Apnoea/Hypopnoea Syndrome (OSA/H) and of late, a new condition has been introduced Upper Airway Resistance Synd...

Warning signs for tipping points (or critical transitions) have been very actively studied. Although the theory has applied successfully in models and experiments many complex systems such as climate systems, there are ongoing debates, when warning can be extracted from data. In this work, we shed light on debate by considering different types of underlying noise. Thereby, significantly advance...

The present study was aimed at investigating the awareness level about warning signs of cancer and its determinants in an Iranian general population. This cross-sectional interview-based survey investigated 2,500 people aged 18 years and over, as a representative sample of Tehran population. Latent class regression was applied for analyzing data. A small (18.8%) proportion of the respondents ha...
